Abstract

Vaulting when setting up dosing organs worsens the quality of the feed dispenser, especially when issuing small doses. The use of a mobile electrohydromechanical platform as part of the feed dispenser allows you to reduce the cost of materials in the feed distribution line and expand the functionality of the feeding equipment. The amount of feed mixture dispensed to the feeder by such feed dispensers can be changed by controlling the speed of movement of the electrohydromechanical platform along a continuous row of feeders, which makes it possible to neutralize the violation of the performance of dosing organs when issuing small doses of feed. The analytical dependence of determining the effect on the norm of the feed delivery rate on the performance of the dosing organ and the parameters of the electrohydromechanical mobile platform (the performance of the dosing device, the parameters of the chassis and a number of others) was obtained. The pneumatic tire of the electrohydromechanical mobile platform is subject to deformation. The rolling radius of the pneumatic wheel must be taken into account when determining the actual speed of movement of the mobile electrohydromechanical platform. The changing mass of feed in the feed dispenser during distribution changes the rolling radius of the wheel, as well as the amount of feed dispensed into a group or continuous feeder. A methodology and experimental setup for studying the change in the rolling radius of a wheel from a vertical load consisting of an electrohydromechanical platform supported by a wheel on a lever connected to a weighing device have been developed. The levels of variation and factors (pressure in the pneumatic tire and the amount of vertical load), as well as the evaluation criterion (the amount of deformation of the pneumatic tire, determined by the rolling radius of the pneumatic tire) are given. The experimental dependences obtained are nonlinear in nature. Studies have shown that when the pressure in the tire of the wheel is more than 1.5 MPa, with an increase in the vertical load of more than 150 kg per wheel, the change in the translational speed of the feed dispenser and the rolling radius of the wheel are within the permissible repartitions and do not exceed 5%.
