Abstract

The invention relates to the mechanization of labor-intensive processes in animal husbandry and improves the uniformity of dosing of feed while simplifying its design and operation. The feeder feed dispenser contains placed in the bunker 1 feed conveyor 2 and feed separator 3 in the form of two beaters. The feed conveyor has a stowage mechanism for automatically controlling its speed with a regulating member 4 in the form of, for example, a casing, which is connected with a pin drum 5 by means of a lever-kuslichnogo transmission unit. In the process of dosing feed, the drum, lying freely on the surface of the feed monolith near the feed chopper, is raised or lowered in accordance with its unevenness, copying them. In this case, the movement of the drum through the elements of the transfer unit is transmitted to the regulator, which opens or closes a certain number of captured teeth of the ratchet wheel 16, thereby adjusting the speed of the feeding conveyor. Turning the levers 6 to the maximum angle up corresponds to stopping the feeding conveyor to select the feed box from the feed monolith protruding towards it by the feed separator.3 CW f-ly, 4 ill.

1 The invention relates to the mechanization of labor-intensive processes in animal production, in particular to feeders m-dispensers, poorly flowing feed.

The purpose of the invention is to improve the uniformity of feed metering while simplifying the design and operation of the feeder.

FIG. 1 shows a schematic of a feed feeder, an axonometric projection J in FIG. 2, a node I in FIG. ; in fig. 3 - node II in FIG. 11 in FIG. 4 - feeder-dispenser

Feed: spruce batcher contains 1 feed conveyor 2 and feed separator 3 in the bunker 3 in the form of two pin beaters. The feed conveyor has a ratchet mechanism to automatically adjust its speed. The ratchet regulator 4, which can be made in the form of a casing or some other one, is kinematically connected with the sensor interacting with the feed monolith through a transfer unit. The sensor is designed as a non-driving pin drum 5 freely supported on the surface of the monolith, which is pivotally mounted on the pivot levers 6 attached to the upper part of the bunker walls in front of the feed stub; the levers have stops 7 that limit their movement upwards; which are installed with the possibility of rearrangement at the upper end of the bunker walls in the notches 8 to change their angle of rotation in the vertical plane. Maximum angle of rotation

levers are selected from a ratio (fig. 4).

The transfer unit consists of a hinged link, with an axis of the drum of adjustable thrust. 9, the opposite end of which is pivotally connected to the lever 10, pivotally fixed ria to the wall of the bunker. The lever 10. Through the rocker mechanism 11 is connected to an intermediate lever 12, which is connected with the regulating body 4 of the ratchet mechanism, while 12 is installed with the possibility of rotation relative to the regulator and changing the length due to the longitudinal notch 13 under the fastening element 14, which is regulator and equipped with a nut 15, made integral with the handle, cooperating with the ratchet wheel 16, the dog 17 is connected by means of the connecting rod 18 to the crank 19, which is connected to the kinematic chain of the drive of the fodder.

The dosing feeder works as follows.

First, using the stops 7 set the maximum angle et. rotation of the levers 6, depending on the physicomechanical properties of the feed, determined by the angle Cf of the repose of the feed in the bunker. Then turn on the drive units and mechanisms. Feed conveyor 2 is supplied to feed separator 3, which, with its synchronously pinning, beaters, separates the feed particles from the monolith and directs them to the feed line (to the discharge conveyor 3 rter, stationary feed dispenser, etc.).

The drum 5, loosely lying on the stern near the feed stub, rises or falls (depending on the surface irregularities of the feed loaded in the bunker 1). The movement of the drum through the elements of the transfer unit is transmitted to the regulator 4, which opens or covers a certain number of captured teeth of the ratchet wheel 16,

thereby adjusting the speed of movement of the feeding conveyor in accordance with the volume of feed in. currently in the feed area-. lit. When the drum rises as far as possible, determined by stops, the feed conveyor stops completely, since in this case the transfer unit rotates the regulation of the organ by an angle ensuring complete overlapping of the teeth of the ratchet wheel. When the drum is fully lowered to the contact of its axis with the upper edge of the hopper, the ratchet mechanism is turned on for the maximum specified feed. In this case, if the feed separator fails to cope with the approaching mass of feed, then a protrusion forms under the drum, which causes its lifting with a corresponding installation of the mechanism in the specified middle position.

The rate of issue is set by changing the working length of the lever 12, at 25 this simultaneously changes the angle position of the lever relative to the regulator 4 and by means of the longitudinal notch 13.

When loading the bunker above the established schedule (Fig. 4), the drum 5 performs the functions of a mechanical stabilizer, constantly working at its top position. Having reached, with stops 7, the drum takes up a rigid position and keeps the feed from further progress. At the same time, the feed is not able to spontaneously be fed to the fodder, since Q is located in relation to the upper feeder of the fodder at an angle of repose. In addition, through the transfer unit, the movement of the feeding conveyor 2 is completely stopped. 45 A working feeder chooses feed from the lower zone of the mound, which, if not moving forward, settles under its own weight. Together with it, the drum 5 is lowered, transmitting a corrective action to the feeding conveyor, after which the latter performs a feeding pulse, and the drum goes back to the uppermost one. . position and continues to hold the ledge from rsshan. The operation of the drum as a stabilizer continues until the entire mound is selected from the lower zone.
