Model essay on mechanical design, manufacturing and automation 1: agricultural machinery automation construction
First, the development status of agricultural machinery automation in China
Definition of agricultural machinery automation: agricultural machinery or equipment can be independently completed without relying on manual operation or senses during its own operation or operation. Agricultural machinery automation can greatly reduce the production principal of agricultural and sideline products, reduce the fatigue caused by farmers' labor, improve the production efficiency of agricultural and sideline products, and also improve the quality and output of agricultural products as a whole. Therefore, the improvement of agricultural machinery should start with reducing production costs, improving production efficiency and quality, and constantly improve equipment to achieve high precision. With the gradual prosperity of China's agricultural economy, mechanical automation technology has played a certain role in promoting the development of modern agriculture. With the improvement of agricultural machinery automation level, the scope of agricultural machinery automation should be further developed and expanded to maintain the overall development trend of agricultural mechanization level. The continuous improvement of agricultural mechanism has enhanced the production capacity of agricultural production enterprises in China. With the continuous strengthening of agricultural machinery capacity, the fields involved are also expanding. The main markets are agricultural machinery sales, equipment maintenance and field work. With the continuous expansion of agricultural machinery automation market, international technical exchanges and cooperation have been promoted. Some large domestic enterprises use market exchange technology to learn foreign advanced technology and enterprise management experience, thus improving the quality and production efficiency of domestic agricultural machinery. However, due to various factors, compared with developed countries, the level of agricultural machinery automation in China needs to be improved, and there are also some problems in the process of agricultural machinery automation.
1. The manufacturing level of agricultural machinery is low.
Compared with developed countries, China's agricultural machinery manufacturing level is low, and more agricultural machinery products are imitated from developed countries. In agricultural machinery automation equipment, only some improvements or additional equipment are made to agricultural machinery to reduce the finished products of agricultural machinery equipment, which limits the application and promotion of products to a certain extent. Therefore, the development of agricultural machinery and equipment suitable for production should be the main development direction of agricultural machinery and equipment in China [1].
2. The development of agricultural machinery automation in China is unstable.
Due to the low development level of agricultural automation in China, it has not been well used in the related agricultural machinery science and technology which is beneficial to China's agricultural development, such as global positioning system, detection and monitoring system and dynamic control system, and can not meet the development needs of China's agricultural machinery automation level. The research and management of precision agriculture in China's relevant agricultural management departments are not strong enough, which leads to the immature and unstable agricultural development in China.
Second, China's agricultural machinery automation development model
Based on the actual problems faced by agricultural machinery automation in China at present, we want to improve the process of agricultural machinery automation in China mainly from the following aspects:
1. The government strengthens the guidance and support for agricultural machinery technology.
Our government can encourage farmers to buy agricultural machinery through a series of policies, and subsidize farmers who buy agricultural machinery, so that the application of agricultural machinery can be more widely popularized. Encourage enterprises and scientific research institutions that produce machinery through incentive policies such as scientific and technological innovation. The government should formulate corresponding policies according to the natural conditions of various regions in China, so as to better promote the development of agricultural machinery automation in China, strengthen the quality supervision and management of agricultural machinery in China, and promote the practical application of scientific research results of agricultural machinery in China. Relevant agricultural machinery enterprises also need to strengthen scientific research and technical input and actively participate in the competition of domestic agricultural machinery products [2].
2. Improve the automation control level of agricultural machinery in China.
In the development of agricultural machinery automation technology in China, it is worth noting that the reliability of agricultural machinery automation level in China needs to be improved. To improve the automation level of agricultural machinery in China, we must first improve the automation control technology of agricultural machinery. The main factors that enterprises should consider when producing agricultural machinery products are: farmers' current requirements for agricultural machinery products, farmers' ability to buy agricultural machinery products, agricultural machinery automation technology adopted, improvement of agricultural products quality, and farmers' convenience in maintaining agricultural machinery products [3].
3. How to promote the development of precision agriculture?
At present, the development process of precision agriculture in China is relatively unstable. Compared with some mature developed countries, the automation level of agricultural machinery in China is relatively low. Further improving the development process of precision agricultural machinery automation in China can not only promote the development and perfection of related technologies of agricultural machinery automation in China, but also show the improvement of agricultural science and technology in China, thus improving China's international status and voice in agricultural machinery automation technology. In recent years, the development of precision agriculture in the world mainly focuses on water and fertilizer saving and other related agricultural technologies. Precision agriculture technology can effectively save water and fertilizer, thus achieving the purpose of saving resources, which is the concrete embodiment of China's sustainable development strategy. While studying foreign advanced technology, relevant personnel in China should concentrate on scientific research and development knowledge, realize precision irrigation and precision fertilization technology, and promote the development of automation level of precision agricultural machinery in China. With the development and strengthening of international intelligence, agricultural robots and intelligent systems have been widely promoted in some developed countries. It can be seen that there is still a great distance between China and developed countries in agricultural machinery. Therefore, China should seize the opportunity of the new era, adhere to the spirit of Scientific Outlook on Development and independent research and development, and vigorously develop China's agricultural automation technology.
Third, summary.
At present, China's agriculture ranks second in the world and becomes a big agricultural country after the United States, but there is a big gap between China's agricultural mechanization equipment technology and other big agricultural countries. There is still a big gap between the spread of agricultural mechanization and the utilization rate of agricultural machinery and equipment compared with advanced countries such as the United States, but with the rapid development of China's economy, the pace of modern agriculture is also accelerating. At the same time, we should also speed up the innovation and management of science and technology in China, operate according to the market trend, seize the opportunity, realize the leap-forward progress of agricultural mechanization, and make contributions to the improvement of China's overall agricultural strength.
Mechanical Design, Manufacturing and Automation Graduation Thesis Mode 2: Research on Digital Design of Agricultural Machinery
First, the application status of digital design technology in agricultural machinery design
Traditional design technology simply meets the needs of users, while digital design technology uses computer technology to shorten the design cycle of products, reduce the design cost of products and carry out post-maintenance. For the design of agricultural machinery, it has a broad market and various designs, but the design of agricultural machinery generally does not use digital design technology, so the design level of agricultural machinery is relatively low for a long time. The application of digital design technology can make the design of agricultural machinery have a better development prospect and make the designed agricultural machinery more perfect. At present, the types of agricultural machinery are relatively fixed, with little change in functions and little innovation. For example, the design of seeder should be based on different sowing objects, that is, drill seeder and precision seeder, and should be designed according to different sowing conditions. In addition, according to the different working principles of seeders, mechanical and pneumatic seeders can be designed, and digital design technology can design these types differently. The application of digital design technology in the design process of agricultural machinery will enrich the types of agricultural machinery, make similar products have different functional distinctions, improve the shortcomings of current agricultural machinery design, and make agricultural machinery more widely and effectively used.
Second, the prospect of digital design technology applied to agricultural machinery design
Because the design level of agricultural machinery is relatively backward, digital design technology will have a broader application prospect in the design process of agricultural machinery. For example, virtual technology can be applied to the design of agricultural machinery, and the collaborative design of digital design technology and agricultural machinery design emphasizes the enhancement of innovation consciousness in agricultural machinery design. The application prospect of these digital design technologies in agricultural machinery design will be introduced in detail below.
2. 1 application of virtual technology in agricultural machinery design
Virtual technology is the use of computer technology to generate three-dimensional image design of products. Through virtual technology, designers can understand the shape of products more clearly. In addition, virtual technology can simulate mechanical movement, that is, it can simulate the function of the designed product, which is convenient for designers to improve the product and ensure the feasibility of product design to a greater extent. Virtual technology can also speed up product design and improve product quality.
2.2 Digital design technology and agricultural machinery design collaborative design and manufacturing
Using digital design technology in the manufacturing process of agricultural machinery can maximize the reliability of products and reduce the cost and design time in the product design process. Using this technology, the design scheme can be changed quickly and the waste of production cost caused by imperfect scheme can be avoided.
2.3 Digital design process of agricultural machinery pays more attention to innovative design.
At present, there is little difference in the types and styles of agricultural machinery, and there is no big improvement. The agricultural machinery produced can not fully meet the needs of farmers, and its function is single. If the design of agricultural machinery can be innovated, the types of agricultural products will be more perfect and agricultural productivity will be improved to a greater extent. Digital design technology can help researchers design different agricultural machinery quickly and reliably, which will be the inevitable development direction of agricultural machinery design in the future.
Three. abstract
China is a big agricultural country, and agricultural machinery plays a very important role in the agricultural development of China. The application of digital design technology will make the development of agricultural machinery in China more perfect and promote the rapid development of agriculture in China.
