Abstract
The authors of the article propose the design of a row cultivator, equipped with combined working bodies, which makes it possible to carry out inter-row weed control in one pass with full cultivation of the protective zones of grown crops. The soil drop distance and the distance between the flat discs located in the adjacent gangs of the row cultivator for thorough covering weed plants with a layer of soilwithout damage to cultivated plants have been substantiated theoretically.
Highlights
In recent years, in world practice, there has been a distinctive trend towards an increase in the use of zero tillage and direct sowing
It is known that with this method of cultivating farm crops, the weed infestation of the fields rises, which requires the use of herbicides and other plant protection products, the cost of which significantly increases the cost of production
When the row cultivator is moving, the A blades 1 loosen the soil at the required depth and cut the weeds, and the flat discs 2 move the soil layer, coming from the wings of the A blades, towards the rows of plants, hill them and cover the weeds
Summary
In world practice, there has been a distinctive trend towards an increase in the use of zero tillage and direct sowing. It is known that with this method of cultivating farm crops, the weed infestation of the fields rises, which requires the use of herbicides and other plant protection products, the cost of which significantly increases the cost of production. In the cultivation of crops, great importance is attached to the development and implementation of soil-protective technologies and anti-erosion machine complexes and tools. In order to reduce operating costs, to increase mobility, and lead time for technological operations, farmers buy wide-span tillage and sowing equipment, in particular, combined machines and units. Ensuring energy and resource saving is a mandatory requirement that applies to technologies, and to soil-cultivating and sowing equipment. The use of herbicides, in addition to the positive side - the destruction of weeds by 70-80%, has a negative side-a decrease in the yield of the cultivated crop to 15%
