Abstract
The article includes an analysis of the state of production of crop production in Ukraine and a description of the shortcomings in the work of cultivators.It was proposed to modernize the construction of cultivators with the help of polymer composite materials. We recommend the introduction of a polymer composite CCPA-6-30 in the construction of cultivators, it has high tribotechnical characteristics
Highlights
Ukraine is one of the largest agrarian countries
We suggest placing them in bushings made of polymer composite materials that will have good physicomechanical and tribological properties
Based on the conducted studies, we can conclude that a promising direction in improving the design of the parallelogram mechanism is the introduction into the design of parts made of polymer composite materials (PCM)
Summary
Ukraine is one of the largest agrarian countries. The area of arable land in Ukraine is about 32,5 million hectares. It is concluded that the main agricultural enterprises in Ukraine are farms with an area of more than 3000 hectares It occupy 39.1% of the total acreage, their number at the same time is only 3.2% of the total number of farms. To improve the technical level of machines and agricultural machinery use structural and antifriction plastics. For this purpose: polyamides, polyethylene with various dispersed and fibrous fillers are often used [58]. Application of polymeric composite materials in engineering and agriculture occupies an important place This applies to soil-cultivating machinery, which is improved for agronomic requirements [4, 9]
