Study of the possibility of increasing the duration of the working process of a feed pusher robot with an active working organ

Abstract

Background. Feed-pushing robots with an active working organ used on farms show low efficiency – they have fewer trips per day compared to other types of robots due to the high energy costs for self-movement, mixing, pushing feed and adding concentrate at the same time with a larger capacity of batteries. At the same time, according to zootechnical requirements in farms, the number of visits should be ten or more times a day. However, in the conditions of ordinary operation, it does not even reach the values stated by the manufacturers themselves. Aim. To study the possibility of increasing the duration of the working process of a feed pusher robot with an active working organ by increasing the number of its passes in ordinary operation. Materials and methods. The research was carried out on two robotic farms, where three feed pusher robots with an active working organ work. The robot's current consumers are analyzed, an analytical technique based on timekeeping works is presented. Results. The obtained analytical expression for determining the number of trips per day of the psut, as well as timing works, show the convergence of the results and are determined in the conditions of ordinary operation of a feed pusher robot with an active working organ of the nday = 7. It has been established that in order to increase the number of trips, a feed pusher robot with an active working body needs to realize the maximum possible operating speed (timely maintenance and ensure the necessary roughness of the floor of the feed passage), or install powerful batteries and replace or upgrade charging stations. At the same time, it is possible to achieve the result of nday= 10 in ordinary operation conditions at lr = 100m, and at lr = 300m it is necessary to install two robots working synchronously in one aisle. The absence or presence of an additional option in the form of a concentrate dispenser does not affect the nday parameter. Conclusions. The study of the working process of the feed pusher robot with an active working organ shows that the number of its trips per day claimed by the manufacturer does not correspond to the values in the conditions of ordinary operation on the farm. Experimental studies show that nday = 7, and it is possible to achieve the nday = 10 declared by the manufacturer only on farms with lr = 100m, and with lr = 300m it is necessary to install two robots working synchronously in one aisle. To increase the nday indicator, timely maintenance is necessary to maintain the maximum possible operating speed, as well as the installation of even more powerful batteries and replacement or modernization of charging stations.
