The dispenser contains a bunker 2 mounted on the trolley, across which in the casing 5 an unloading auger 6 is placed. When switching on its drive due to the interaction of the leash 16 with stationary pins 32 feeding troughs 29 of the feed are mixed to the unloading window 10 of the casing. At the same time, the feed mass due to the increased winding pitch at the exit section is accelerated and the additional winding 11 fixed on it is leveled and uniformly pressed to the blades of the impeller 12, which is mounted on the auger shaft with the possibility of sliding in the plane of the unloading window.

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 accuracy of feed metering.

FIG. 1 schematically shows a feed dispenser, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - feed dispenser, longitudinal section; in fig. 4 is a view B in FIG. 3; in fig. 5 - kinematic diagram of the unloading auger drive; in fig. b - scheme of placing the pins at the feeders; in fig. 7 - leash, general view.

The feed dispenser contains a hopper 2 mounted on the trolley 1 with mixing augers 3, a feeding screw 4 and a discharge screw 6 placed in the housing 5 across the hopper 6. The latter is driven from the cardan shaft 7 through the clutch electromagnetic clutch 8. The feed screw is located above the discharge screw and has counter-directed 20 windings, the ends of which are provided with blades 9 fixed to them fixed at an angle of 10-20 ° to the axis of the feed screw. The lower part of the intake area of the discharge auger is located in leather 15

the control 33 with movable deactivating pins 34 and 35. To set the rate of delivery of feed on the brackets, a ruler 36 is fixed, having a scale of feed to be dispensed. To prevent breakage of the casing of the discharge auger and of the leads when the dosing unit is brought into the livestock building along the side of the bunker 2, the fender bar 37 is fixed.

Feed dispenser works as follows.

Feed is loaded into the hopper 2 while simultaneously rotating the screws 3 and 4 to mix the feed components. The feed screw 4 of the feed moves to the discharge screw 6, but since it does not work during loading, the mass is formed over it and it rises with blades 9 to the mixing screws 3, is carried by them to the end walls of the hopper, falls into the feed screw, and the cycle is repeated is.

When feeding the dosing unit, the dosing unit moves along the aft passage along cortex 29, the leash 16 locates onto the fixed pin 32, deviates, overcoming the resistance of the spring 24, and turns the tongue 26 into the slot of the contactless switch 30

he, and its upper part is above the bottom of bun 27. The electromagnetic clutch 8 is turned on and the unloading screw 6 begins to rotate, yielding feed to the feed rack. Then the leash 16, jumping off the pin 32, returns to its original position under the action of the spring 24. During the issuance of feed feed screw 4 podpressovaya mass to the discharge auger, ensuring its complete filling. The unloading screw moves the mass to the unloading window 10, accelerates and loosens in the place of the schagary's increase, is also transported by additional winding 1I and more evenly compresses the blades of the impeller 12, which with their bevelled, curved and pointed inner ends cut off the incoming mass and dump it through the pitched tray of the discharge window into the feeder. The delivery of feed continues until the lead 18 finds on pin 35 and disengages clutch 8. At the same time, brake 15 is turned on and the unloading auger stops abruptly. When the auger stops, the curved ends of the impeller blades lock the mass in the auger, preventing it from emptying out arbitrarily. The visor 14 ensures that the mass erupts after the auger stops, always from two quarters of the impeller, in whatever position it stops.

 kerah. The unloading screw at the outlet section I is made with the step of winding increasing to the unloading window I 10, and is provided with additional winding 11 having a height increasing to the unloading window. The out-weighing auger is also equipped with a rotary-mounted four-blade j impeller 12 installed in the plane of placement of the discharge window; its inner ends are 13-fold and the mouths of which are bent in the direction of rotation, have cutting edges and are located. | us at obtuse angles to the longitudinal red | m blades. The end of the casing sidewall, opposed to the unloading auger at the unloading window, is provided with a visor 14. To prevent clogging, the upper part of the casing of the unloading auger at the outlet is raised and rectangular. Feed dosing is provided by controlling the electromagnetic clutch 8 of the clutch, equipped with a brake 15, from a sensor mounted on the bunker, consisting of leads 16-18. Each lead is made of sleeves 19, Installed by cable 20 with the help of spring 21 and slider 22 placed in cup 23. In the initial position, the lead is held (TF by spring 24 and can be rotated cn axis 25. To the bottom of the attachment lead-) Hook 26 that interacts with the contactless 1 | contact switch 27. The clutch, brake and control system have a self-propelled (5th generator. 28)

When the unloading auger stops, the feeding screw 4 continues to rotate and, in the case of a mass spiral, throws its shovels into the separation racks. 30 is fixed by 55 cams 9 to the stirring pins 3, which the transmitter, made in the form of brackets 31 with the fixed connecting pins 32 attached to them and then taken away to the end walls of the bunker. This prevents the compacting of the mass over the unloading cheek and securing

the control 33 with movable deactivating pins 34 and 35. To set the rate of delivery of feed on the brackets, a ruler 36 is fixed, having a scale of feed to be dispensed. To prevent breakage of the casing of the discharge auger and of the leads when the dosing unit is brought into the livestock building along the side of the bunker 2, the fender bar 37 is fixed.

Feed dispenser works as follows.

Feed is loaded into the hopper 2 while simultaneously rotating the screws 3 and 4 to mix the feed components. The feed screw 4 of the feed moves to the discharge screw 6, but since it does not work during loading, the mass is formed over it and it rises with blades 9 to the mixing screws 3, is carried by them to the end walls of the hopper, falls into the feed screw, and the cycle is repeated is.

When feeding the dosing unit, the dosing unit moves along the aft passage along the perturbation 29, the leash 16 finds it at the fixed pin 32, deflects, overcoming the resistance of the spring 24, and turns the tongue 26 into the slot of the contactless switch. When the unloading auger stops, the auger 4 continues to rotate and in the case of a spiral the masses throw it out with shovels 9 to the stirring jaws 3, which then carry it to the end walls of the bunker. This prevents the compacting of the mass over the discharge puff and ensures the reliability of the process and the uniformity of the feed.

Upon further movement of the dispenser, the cycle repeats, and the amount of feed dispensing is determined by the operation time of the unloading auger or the distance between the pins 32 and 35. The latter, fixed on the guide 33 with the possibility of mixing, are set to the discharge rate on a scale of 36 according to with animal productivity. For the purpose of dosing separately the root crops and concentrates or two different mixtures, an additional movable pins 34 are installed on the yushi line, 33, which interact with the lead 17. A special toggle switch is provided to switch the operation of the unloading auger from the upper 34 or 35 lower pins.

The springs 21 are tensioned so that when they meet the leads with the pins, they are bent back, retaining their linear shape, and when meeting with other obstacles (for example, gates), they, moreover, are bent at the ends of the sleeves 19 and do not go out therefore from the system.
