Електросапа – культиватор «Мрія»

Abstract

In this article, we propose the design of a universal electric hoe - a cultivator with a balancing drive wheel for inter-row cultivation of row crops. Currently, chemical methods and mechanical loosening are widespread in modern agriculture, but concerns about the use of herbicides, especially in "organic farming," leave no choice. We propose a machine that allows for inter-row cultivation of any row crops, even by a child. The proposed device is to be equipped with an electric motor with an electric battery, which will allow for greater mobility, low noise and vibration levels, as well as a set of tools to perform all technological operations when growing row crops. Ninety percent of manual labor in the cultivation of garden crops is spent on sowing and subsequent cultivation of row spacing. Therefore, the device must have a certain set of tools, such as a "hiller paw" for cutting furrows and hilling; a "one-sided paw" for removing weeds from the row spacing; a "lancet paw" for deep loosening and crust destruction. As can be seen from the above, manual weeding is the most effective method of weed control for working on a personal plot. However, due to the high labor intensity of the work, the task of creating a device for processing both inter-row and intra-row weeding is now being addressed. Field tests have shown that this device performs all the tasks in full, and the battery capacity, subject to continuous processing, is enough for 400 m2. The next step in improving the functional characteristics of the proposed design is to equip the electric chopper-cultivator with a device for inter-row cultivation. Inter-row cultivation is a method of weed control that involves removing weeds from the internal space between plants in one row. This process can be an important step in crop care and is aimed at reducing competition between weeds and crops. It is important to perform inter-row weeding in a timely manner, especially in the early stages of crop growth when weeds are just beginning to gain weight. It is economically feasible for the operator to control the machine manually. After a short practice, the control accuracy can reach several centimeters.
