Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, machines for the preparation of animal feed.

The purpose of the invention is to improve the quality of the feed and the performance of the mixer of the steamer.

FIG. 1 shows the mixer-steamer, general view; figure 2 - the shaft of the agitator with ctpyftHbn m pumps.

The mixer-steamer consists of the case I, which is a tank for preparing feed, an agitator consisting of hollow shafts 2 with blades 3 fixed to them. The mixers are equipped with hollow stands 4 on which the jet pumps 5 are fixed. The mixer case has an unloading screw 6 and a water, steam and active medium supply system consisting of a pump 7 with an engine 8, switching valves 9-12, a mixing valve 13 with a filter 14, connected via pipelines 15 with a hollow shaft 2 agitators.

The shaft of the agitator consists of a pipe 16, the ends of which are pressed into spikes 17 and 18. A cushion 19 is attached to the shaft pipe, on which the housing 20 is installed; 4 jet pumps, consisting of active 21 and passive 22 nozzles connected by means of nozzle 23 and nuts 24 with a hollow sleeve 25. Between the shaft and the nozzle 23 is installed gasket 26.

A drive sleeve 27 is attached to the movable sleeve, which receives rotation through the shaft 28, which is fastened with a screw on the drive sleeve, from the output gear shaft 29 of a bevel gearbox placed inside the pipe. A thrust cushion 31 is attached to the gearbox housing 30, and through the input gear shaft 32 of all gearboxes installed inside the pipe, there passes a square axis 33, one end of which (cylindrical) enters the right spike 17. At the other end of the axis 33 a figure washer is fixed 34, which is pressed between the sleeve 35 and the pipe 36. The sleeve 35 is connected via a sleeve 37 to a tee 38, to which a pipe 39 for supplying water or a mixture and a pipe 40 for supplying steam are connected. The conduit 36 is rigidly connected with the cup 41 to the steamer-mixer body, and the end of the conduit enters the left axis,

which, to reduce friction, is mounted the bearing sleeve 42. A seal sleeve 43 is mounted on the pipe 36, which is pressed by the end face

by means of a spring 44 to the end of the left spike 18, with the disks 45 and 46 attached to the ends of the seal bushing and the axis, and a gasket 47 (48) is located between the end of the bush 43 and spike 18. Mating density pipeline - bushing seal is provided with rubber rings 49. I

Mixer steamer works as follows.

In the feed steaming mode, the tank is filled with the initial components, while the level of the components must be Bbmie

jet pump. The drive of the mechanical agitator is turned on after the mixer body has been filled with at least one third of its volume. After filling the tank, the steam supply valve 10 is fully opened, and the valves 9, P and 12 are closed. Steam through pipe 36 is fed into the inside of pipe 16 and then to the active nozzles of the jet pump 5. From the active nozzles of the 21 pumps, the medium exits at a faster rate, which creates a vacuum in the passive nozzle. The vacuum entrains the mixture and containers into the chamber between the nozzles, where steam and the mixture are mixed and out of the jet pump into the container. When the agitator shaft rotates, the jet pump rotates around the axis of the stand, intensifying mixing. Forced rotation

through a roller 28, which receives the drive from the gear 29 of the bevel gear. The meternum 32 is still in a fixed state.

In the mixture circulation mode, valves 10 and 9 are closed, and valves 12 and P are open. The mixture through the filter 14 enters the mixing inlet 13 and enters the pump 7, which pumps the mixture into the active medium supply system. Further movement of the mixture is similar to the movement of steam.

In the wash-off mode, valves 12 and 10 are closed and valves 9 and II are open. In the suction cavity of the pump 7 enters the water, which the pump pumps into the system of the active medium. Water flows out of the active nozzle and hits the wall of the housing. For better washing, you can turn on the mechanical stirrer drive.

The mixture transfer system is as follows: valves 10 and 11 are closed, and valves 9 and 12 are open. The water enters the mixing intake and then through the filter into the body of the steam tank.
