Description

one

The invention relates to the field of engineering for livestock and fodder production, in particular, to devices for dispensing feed on farms and complexes.

The purpose of the invention is to increase the reliability in operation by preventing the feeds from hanging on the guide tray while simultaneously increasing the scientific research institute for the accuracy of their metering and simplifying the design of the device.

FIG. 1 shows a device for dispensing feed, in plan view; in fig. 2 is a view A of FIG. one.

The device for dispensing feed includes a hopper with a discharge screw 2, provided with an outlet end with a guide tray 3 and a drive mechanism. The latter is designed as mounted on the shaft of the unloading screw of the pneumatic turbine. 4 and the braking air assembly 5 interlocked by the pneumatic actuators 6. The guide pan is equipped with a scraping device in the form of a scraper 7 driven by the pneumatic cylinder 8 interlocked with the screw drive mechanism of the unloading screw by means of a pneumatic pipe 9 with a pneumatic distributor 10. The rod 1 of the pneumatic cylinder is spring-loaded with a spring 12 and a pneumatic conduit 9 with a pneumatic distributor 10. The rod 1 of the pneumatic cylinder is spring-loaded with a spring 12 and a pneumatic cylinder with a pneumatic distributor 10. return the scraper 7 to its original position. The pneumatic distributor 10 is controlled from the lugs 3 of the crush plates 14 mounted on the transporting body 15 with the ability to move relative to the bunker 1 and interacting with the crane 16 communicated with the pneumatic distributor pneumatic line 17. The output end of the guide chute is equipped with a funnel 18 placed directly above the feeders. A pneumatic line 19 is also connected to the pneumatic distributor, which, together with the valve 16 and the pneumatic line 17, communicates with the compressor. The pneumatic cylinder is made with a hole 20 in

5042

its casing designed for air discharge.

Device for dosed distribution of feed works as follows.

Compressed air from the compressor through the pneumatic line 19 through the pneumatic distributor 10 is supplied to the blades of the pneumatic turbine 4 and to the pneumatic node 5 of braking, disengaging the shaft of the unloading auger 2 and ensuring its rotation. As a result, the dose of feed is fed to the guide chute 3. At the same time, the transport body 15 is switched on, moving forwardly moving the feeders I4. As soon as the first stop 13 switches the tap 16,

air is opened to the pneumatic distributor. by the pneumatic line 17. In this case, the distributor intersects the pneumatic line 9 and at the same time the air is directed to

the pneumatic cylinder 8, as a result of which the screw shaft stops instantly due to the shutdown of the pneumatic turbine and actuation of the braking unit, for example, from the built-in

springs into it, and the piston rod 11 of the pneumatic cylinder begins to move. Simultaneously moving stock | the scraper 7 also moves, dropping a dose of feed through the hammer 18 into the first feeder. When the piston of the pneumatic cylinder progresses beyond the opening 20, the air in the pneumatic cylinder housing is vented to the atmosphere and

the spring 12 the scraper returns to its original position. With this, the interaction of the first stop 13 with the crane 16, .a is stopped. air entering through the air line 19 through

pneumatic distributor, again begins to flow to the drive mechanism of the discharge auger, drive it into rotation. The process of distribution of feed in subsequent feeders is similar.
