ULTRA-LOW VOLUME SPRAYER'S PERFEC-TION FOR GARDENS AND VINEYARDS PRO-CESSING
05.20.00 Processes and machines of agroengineering systems
Description
The urgency of the task in creating a reliable plant protection system is the improvement and development of new technologies for spraying crops on the basis of fundamentally new agricultural requirements at a higher quality level, increasing productivity, reducing energy costs and greening protective measures. Pneumatic slotted sprayers have great design capabilities allowing obtaining operating parameters necessary for the specific task of the sprayer. In this regard, we have proposed a technological scheme of the sprayer in the garden-vineyard version. To do this, the sprayers are placed in pneumatic ducts of the fans mounted on the sprayers. It is possible to reduce energy and resource costs, to achieve high quality indicators of the process and to increase the level of environmental friendliness by developing technical means for ultra-low-volume spraying. The principal novelty in solving the problem of ultra-low volume spraying is the use of KubSAU design pneumatic sprayers on the sprayer, and the scheme of the technological process, allowing the reduction of the working fluid and pesticides doses rate, resulting in reduced operating costs to support operations: preparation of working fluids and filling the sprayers. To process two rows simultaneously, it is possible to use sprayers equipped with two centrifugal fans with the installation of pneumatic slit sprayers with fixation in the ducts that they overlap, forcing the air from the fan to pass through the atomizer body, mixing with drops of working fluid. In this case, the speed of the air-droplet jets increases and more efficient use of the air jet from the fan occur. Along with the use of sprayers, equipped with KubSAU design pneumatic sprayers, to combat pests and diseases, we propose to use a sprayer to combat weeds in the trunk area of perennial plantations. Thus we have a family of ultra-low volume sprayers with pneumatic slotted sprayers of the Kuban State Agrarian University design

PNEUMATIC SLIT SPRAYER PARAMETERS STUDY
05.20.00 Processes and machines of agroengineering systems
Description
As a result of scientific analysis of the effective plant protection by spraying them with protective-stimulating liquids, the most progressive pneumohydraulic processing method was chosen, enabling the use of a wide mode range. The proposed pneumatic sprayer design can be used to equip sprayers, pollinators and combined units to perform basic operations with the use of pesticides and fertilizers. Using liquid crushing through exposure to working fluid flowing from the feeding tubes of sprayers (jets) with a high-speed air jet, it was possible to carry out the spraying process in a low-volume and ultra-small-volume way in a highly dispersive airborne jets. To study the air-borne jet parameters, providing the working fluid spraying quality as a polydisperse system, we have used a probabilistic-statistical analysis method. It studies variation range of signs according to the classes. Theoretically, the air-borne jet forming process by a pneumatic slit sprayer was considered. Using the three-factor central composite rotatable uniform plan (CURUP), the influence of three factors (surge tank position in cm, air pressure MPa and the feeding tube inclination angle in degrees) on the sprayer performance and the surface response on the working fluid median-mass diameter was determined. It was found that the response surfaces have a form of a paraboloid, the extremum of which is observed at an air pressure of 0.15 MPa (the center of the plan) and the tube installation angle in the spray housing equal to 60 degrees with the middle surge tank position. The maximum coating density of the treated object was 95 pieces / cm2 at the same position of the surge tank and air pressure in the pneumatic line of 0.3 MPa. It was proved that ultra-low volume spraying can be carried out in wide ranges of initial data while observing spraying quality requirements according to the drop median-mass diameter, the average coating density and their distribution uniformity
