Annotation

The paper considers the problem of reducing the drive power of the mechanism for separating stalk feed from trench storages by the batch method by developing and substantiating the parameters and operating modes of the hydraulic drive system. The structure and principle of construction of a system of hydraulic drives of the mechanism for separating a portion of stem feed are proposed. This will significantly reduce the power of the used hydraulic motors by simultaneously controlling the cutting speed of the monolith of stem feed and the feed of the cutting device.
The analysis of changes in the physical and mechanical properties of stalk forage (silage and haylage), depending on the height of occurrence in the trench storage, has been carried out.
The process of separation of the stalk feed from the feed monolith is considered. The complexity of the technological process of separating the portion of the stalk feed from the feed monolith due to the change in the physical and mechanical properties of the feed from the height in the trench storage and the lack of adaptation of the loader drive to such differences is indicated.
A basic hydraulic diagram of the loader drives is proposed, which is based on the dependence of the cutting force of the material on the parameters of cutting modes. The theoretical foundations of the calculation were formulated by I. Timme and later adapted to the peculiarities of the work of agricultural machinery by V.P. Garyachkin. This theory allows you to determine the cutting force on the working body of the cutter bar depending on the cutting speed, feed of the cutter bar and depth of cut.
An adaptive hydraulic drive of the mechanism for separating the stalk feed is proposed, which makes it possible to coordinate the operation of the cutter bar drive with its supply. The possibility of reducing the drive power of the mechanism for separating the stalk feed to 5-6 kW when using a system of hydraulic drives with a mechanism for adapting the working bodies to their working conditions has been confirmed.
The modes of operation and the possibilities of increasing energy efficiency, competitiveness of technological machines and aggregates of the agro-industrial complex, by developing and substantiating the parameters of the hydraulic drive system, are indicated.

Keywords: stalk feed, moisture, density, drive, cutting, blade, hydraulic motor, hydraulic cylinder, power.
