Description

This invention relates to the mechanization of labor-intensive processes in animal husbandry, in particular to feed dispensers.

The purpose of the invention is to improve the uniform distribution of feed across the width of the feeders.

Fig. 1 schematically shows a feed dispenser, an axonometric projection; figure 2 is the same, top view; on fig.Z - the same, cross section; Fig. A is a diagram of the distribution of feed across the width of the feeders; Fig. 5 is a diagram of the connection of hydraulic cylinders to a common hydraulic distributor.

The feeder contains a trolley 1, on the frame 2 of which the metering tanks 3 are installed on both sides, which are provided with loading means. The latter is made in the form of a bunker 4 having a chute 5 located on its periphery with a closed scraper conveyor 6 placed in it. The lower ends of the bunker walls are located relative to the bottom 7 of the chute with a gap 8, an adjustable gate 9 through which the ends of the scraper 10 are inserted into the bunker conveyor 6. The pitch of the scrapers 10 is equal to the pitch of the discharge windows 11, which are made at the bottom of the gutter, each of which communicates with the dosing capacity of each feeder 12 in each stall 13. Gates 14 are attached to the back plane of the scrapers, which are installed with the possibility of overlapping unloading windows.

The dosing tanks have openings above the feeders towards their front walls 15 by means of a drive hinged bottoms 16, which, in the open position, block access of animals to the feed. Dosing tanks are hinged on the frame and equipped with a drive turning in a vertical plane from the rear of the feed boxes to the front of them. Each dosing container is made telescopic from the upper cylinder 17 and coaxially with the lower cylinder 18 placed on it. The hinge 19 of the dosing container to the frame is located at the front edge of the upper cylinder. The rotation drive of the metering tanks is complete in the form of 2 hydraulic cylinders 20 hinged on the frame, each of the piston sticks 21 each

Replen to the interlocking upper cylinders 17 of the bar 22. The opening opening of the bottoms is made in the form of fixed on the lower cylinders

18 hydraulic cylinders 23, the stem 24 of each of which is harned

to one of the shoulders of the two shoulders arm 25, the other shoulder of which is attached to the bottom. The cylinders 20 and 23 are interlocked with each other by means of a hydraulic distributor 26, which is controlled by the operator, mounted with the tractor carriage 1.

For the drive of the conveyor 6, there is a drive sprocket 27, kinematically connected via a gearbox 28 and a drive shaft 29 to the tractor's power take-off shaft. The conveyor 6 is provided with a marker 30, when placed in which the scraper 10 of the shutter 14 completely overlaps the unloading window 11. The cart 1 is equipped with guides 31 for its wheels 32.

The lower cylinder 18 of each dosing tank is equipped with a cable-block drive 33 for moving it relative to the upper cylinder 17, the block

34 which is fixed coaxially to the hinge

19th fastening to the frame, and its cable

35 has a control lever 36 for setting doses. Elastic guides 37 are installed under the discharge ports 11, which enter into the metering tanks. The bottom of the last 16 spring springs 38.

The feeder works as follows.

The cart 1 moves along the guides 31 along the feeders 12 by means of a tractor, while the metering containers 3 are located above the feeders. When dispensing tanks are placed symmetrically with respect to feeders and stalls 13, the cart stops. At the beginning with the help of levers

The control units adjust the metering tanks to the specified volumetric delivery rates by moving their lower cylinders 18 along the upper cylinders 17, which correspond to the productivity of the animal in the stall, by fixed cables 35. Then, the metering tanks are filled with feed from the bunker 4 through the gap 8 with scrapers 10 of the moving conveyor 6, which pick up and evenly feed the feed into the discharge ports 11 of the bottom 7 of the chute 5 and further into the cylinders of the metering tanks. Thereafter, the conveyor stops at a position where one of its scrapers is located at the marker 30, and the shutters 14 close the discharge ports. The subsequent activation of the distributor distributor 26 simultaneously activates the hydraulic cylinders 20 and 23, as a result of which the metering containers rotate around the hinges 19 from the rear to the front walls 15 of the feeders and gradually open the bottoms 16 in the direction of rotation of the metering containers, ensuring uniform distribution of feed across the width feeders. At the same time, the animals are prevented from getting to the food due to the overlapping of the free space above the feeders by the bottoms of the dosing tanks. After unloading from the feed, the cylinders of the metering tanks and their bottoms return to their original position and the carriage moves to the next row of feeders. After adjusting the dosing tanks to the specified norms, the delivery to the feeders of the feed is carried out similarly.
