Description

The invention relates to the mechanization of labor-intensive processes in animal husbandry, in particular to units for harvesting feed residues.

A device for cleaning and washing feeders [SU 1178369 A, A01K 5/00, 09/15/1985], which consists of a main brush, a drive and a washing device with a nozzle for supplying washing liquid, a planetary mechanism. The feeders are mounted on an endless conveyor.

The disadvantages of this design are: the bulkiness of the structure, high noise during operation and, most importantly, a large specific water consumption per unit of cleaned area, leading to a significant increase in the volume of effluents.

Known feeder [SU 1657134 A1, A01K 5/00, 06/23/1991], which consists of a fixed and rotary sections of the gutter mounted on the frame, scraper mechanism, gear motor, hydraulic cylinder.

The disadvantages of the feeder are: high metal consumption of the structure, as well as during the feeding process, the probability of spillage of food between the fixed and rotary sections of the trough.

The closest analogue is the unit for distributing feed and harvesting their residues [SU 1402311 A1, A01K 5/02, 06/15/1988]. The unit for distributing feed and harvesting its residues contains a feeder and a suction head for harvesting feed residues, as well as a fan.

The disadvantage of this unit is the pollution of the room with the exhaust gases of the tractor, low efficiency of the fan.

The objective of the invention is to increase the productivity and quality of cleaning feeders, a more thorough removal of the remnants of undernourished food and preventing its acidification and drying on the walls of the feeder.

The essence of the invention lies in the fact that for the implementation of this task, the proposed device for cleaning the feeders is made of a frame, chassis, gear motor, belt drive, hydraulic system, hopper for residual feed, boom, cleaning drum, feeders.

This is achieved by the fact that a cleaning drum is provided in the device for cleaning the feeders to remove residual feed from the middle of the feeder and along its edges. An arrow is mounted in the middle of the cleaning drum. To raise and lower the boom with a cleaning drum, power hydraulic cylinders are provided, which are installed in the middle of the cleaning drum.

In the cleaning drum, one support is stationary, it is welded to the boom. An external bearing is mounted on the support, on which the housing is fixed. Brushes are installed on the body. Bearings are installed inside the support, a shaft is installed in the bearings. A cover is mounted on the shaft that connects the shaft to the housing. The shaft is mounted with the possibility of rotation of the pulley. The pulley is mounted on the shaft using a spline connection. The pulley is designed to drive the cleaning drum into rotation. A cotter pin is installed to prevent axial displacement of the shafts and pulley. To prevent axial displacement of the bearings, snap rings are installed.

One fixed support has a ring profile and is welded to the boom. Another fixed support also has a ring profile, but is welded to the boom through an L-shaped mount. L-shaped mounting is necessary to ensure rotation of the driven pulley. The trunnions are welded to the shafts. Slots are provided on the trunnions. The boom is mounted in the center of the cleaning drum. A belt drive is installed on the boom. Brushes are installed around the perimeter of the cleaning drum and are designed to remove residual feed from the feeder. For a more thorough removal of food residues from the sides of the feeders, the brushes are made protruding to the sides of the cleaning drum.

A device for cleaning feeders will be clear from the following description and the accompanying drawings.

Figure 1 shows a General view of a device for cleaning feeders, Figure 2 shows a cleaning drum, Figure 3 shows a view G, a section of a bearing assembly of a cleaning drum, Figure 4 shows a view D, a section of a bearing assembly of a cleaning drum and a driven pulley , Fig. 5 shows a section EE of the spline connection, the pulley is mounted on a pin.

Figure 1 shows a device for cleaning feeders, which consists of a running gear 1, which is designed to move from boxing to boxing, a hopper 2 for collecting residual feed, cleaning drum 3, boom 4, which is attached to the cleaning drum. To prevent spraying of residual feed during harvesting, a casing is installed on the cleaning drum 3. Power cylinders 6 are designed to raise and lower the boom 4 with the cleaning drum 3 into the feeder 7. A gear motor 9 with a belt drive 10 is installed on the frame 8. 9 and the belt drive 10 are designed to rotate the cleaning drum 3.

The cleaning drum (figure 2) consists of a fixed support 11 (figure 2, 3), it is welded to the boom 4. The support 11 is made with a profile in the form of a ring. An external bearing 12 (FIG. 3) is mounted on the support, on which the housing 13 is worn. Brushes 14 are installed on the housing 13 (FIG. 2). Bearings 15, 16 are installed inside the stationary support 11 (Fig. 3). A shaft 17 is installed inside the bearings 15, a cover 18 is installed on the shaft (Fig. 2), which connects the shaft 17 to the housing 13. The circlip 19 (Fig. 3) is intended to ensure the immobility of the bearing 15 in the axial direction.

On the shaft 20 using a spline connection (figure 2, 4) installed pulley 21 (figure 2, 4).

The pulley 21 (figure 4) is designed to drive the rotation of the cleaning drum 3 (figure 2). The support 22 (figure 2, 4) is made with a profile in the form of a ring and is fixedly attached to the boom 4 with the help of a L-shaped rack. The L-shaped stand is designed to allow the rotation of the pulley 21. The pin 23 (Fig. 4) is welded to the shaft 17. The pin 24 is welded to the shaft 20. The sleeve 25 (Fig. 3) is designed to fix the bearing 16 in the axial direction. The pin 26 (figure 4) is designed to fix in the assembled position of the pins 23, 24 and the pulley 21. The retaining ring 27 (figure 3) is designed to prevent axial movement of the housing 13 with brushes 14 and bearing 12.

A device for cleaning feeders works as follows. After stopping opposite the feeder 7 of the device for cleaning the feeders (Fig. 1), using the power cylinders 6, lower the boom 4 with the cleaning drum 3 until the brushes 14 (Fig. 2) come in contact with the feeder 7 (Fig. 1). Then, the gear motor 9 is turned on. Through the belt drive 10, the torque is transmitted to the pulley 21. The torque from the pulley 21 (Fig. 2) is transmitted via spline connection (Fig. 5) to the axles 23, 24 of the shafts 17 and 20. Respectively the moment is transferred to the lid 18 (FIG. 2), to the housing 13 and to the brushes 14. The remains of feed in the feeder 7 (FIG. 1), when interacting with the rotating cleaning drum 3, fall into the hopper for residual feed 2. When collecting residual feed from the feeder 7 the device for cleaning the feeders is moved using the chassis 1. In the cleaning process, The device for cleaning the feeders is stopped at the beginning of the feeder 7 and with the help of the hydraulic cylinders 6 the cleaning drum is lowered so that the brushes are pressed snugly against its sidewall. The device for cleaning the feeders is also stopped at the end of the feeder so that the cleaning drum 3 is lifted out of the feeder without damaging the feeder and the cleaning drum. When the cleaning drum 3 rotates, the feed particles fall on the protective casing 5 and do not fly away indoors.

Such a device for cleaning feeders provides an increase in the productivity and quality of cleaning feeders, a more thorough removal of the remnants of undernourished food and the prevention of its acidification and drying on the walls of the feeder.
