Development and justification of the application of the clamp of atomizer body clamp in strip differential spraying technology

The article presents a new technology of plant protection and care of vegetable crops in relation to the spraying system. As a result of the conducted work the analysis of the conducted research of methods of chemical plant protection is presented. The obtained comparative results showed that the proposed method of plant treatment with the use of the developed sprayer body clamp allows to significantly increasing the quality indicators of spraying and at the same time reduce economic costs.

Introduction. Soil The development of vegetable crops production is a significant direction in the agro-industrial complex of our country. Increase of yield depends on the applied technologies of cultivation of agricultural crops. At the same time, the main criteria of efficiency of the used technologies are energy and resource intensity of the applied agricultural machinery. Increasing the productivity of machines used in technologies, it is necessary to take into account agrotechnical requirements to the conducted production operations. Thus, in the system of protection of agricultural plants from diseases and pests a big role is given to the operation of spraying. Improvement of methods of protection of cultivated crops from diseases and pests is included in the application of advanced methods and preparations for spraying.

Object. The object of research are devices of fixation of nozzle bodies on sprayer booms.

Materials and methods. Band differentiated spraying is economically advantageous when applying liquid fertilizers with high concentration or specific composition, including microelements or specialized fertilizers for specific crops, as well as protection products. In order to increase the quality indicators of drug distribution when spraying plants, it is proposed to carry out this treatment with nozzles set at an angle of 45 in the vertical plane in the direction towards each other installed above the centers of row spacing of row crops. The use of this scheme of installation of atomizers on spraying allows forming a powerful stable flow when combining two directed towards each other. This method is achieved by using clamps of atomizer bodies, which have the ability to move operatively along the sprayer boom to set the required band of treatment of the plant in accordance with the growing season.

Results and conclusions. In the work the analysis of applied clamps of atomizer bodies for use in the technology of strip differentiated local application of working solution was carried out. Shortcomings in the use of used clamps were revealed and an improved design of the clamp was proposed, which provides practical and convenient use of the clamp and increases the speed of sprayer preparation for work. At the same time the increase of qualitative indicators with the reduction of economic costs of strip spraying is realized.
