Description

The invention relates to batchers of stalk feeds used in livestock farms.

By main auto No. 701611 known silo dispenser-unloader, comprising a hopper, with shafts arranged in its lower part, equipped with staggered fingers, and an unloading screw mounted under the shafts, a grill interacting with the fingers installed in the bunker above the shafts, the shafts being attached to to the bunker by means of shock absorbers (1).

A disadvantage of the known dispenser-unloader is that it is not universal, since it is applicable only when dosing a single feed forks, namely silage.

The disadvantage is due to the fact that, taking into account the physicomechanical properties of the stalk feed, it becomes necessary to change the distance between the ends of the fingers of the shafts, which is not provided for in the known construction.

The aim of the invention is to ensure uniform unloading of stalk feed.

The goal is achieved by the fact that in the dispenser-unloader, the shafts with fingers are mounted on the frame with the possibility of moving in a horizontal plane, and the side walls of the hopper interacting with the shafts of the shafts are divided in height into three parts, the middle part of each side wall being pivotally connected and is provided with a link through which 1Q it is connected to the bottom of the side wall.

Figure 1 schematically shows the proposed dispenser-unloader of stalk feed; figure 2 is a view along arrow a in figure 1.

, The stern feed dispenser-unloader contains a hopper 1, in the lower part of which shafts 2 are installed with pyls 3 arranged in a checkerboard pattern, the shafts being arranged so that the shaft axis is in the same plane as the bunker wall located above it, and at the base of the latter, slots are made for the passage of the shaft __ fingers. In the hopper 1 above the shafts 2 there is a grid 4 interacting with the fingers 3, and the shafts are attached to the hopper by means of shock absorbers 5 having the form of springs, the rigidity of which is regulated by ^υ screws 6.

The side walls of the hopper are divided in height into three parts 7, 8 and 9. '

The upper part 7 of each wall is connected to the middle 8 by means of a hinge 10, and the lower part 9 of the wall overlaps the average height necessary for 5 so that when the shafts 2 are not moved, the wall is disconnected, and connected with it by the wings 11.

The lower part 9 of the wall is connected to the 'grill by means of a hinge 12'. On the 10 frame 13 in the places of attachment of the shock absorbers, slots 14 are made, which allow changing the distance between the shafts 2. The shafts 2 are moved together with the grill 4 and 15 by the lower part 9 of the side walls. Under the shafts 2 there is an unloading conveyor 15. The drive on the shafts 2 is carried out through a cardan drive.

The dispenser-unloader of stem stalks-2Q mov works as follows.

The feed loaded into the hopper 1 is fed from it to the unloading conveyor 15 using shafts 2 rotating towards each other, equipped with 25 fingers 3, freely passing through the grooves of the grate 4 and the slots in the side walls. Due to the presence of a grill 4 over the shafts 2, interacting with the fingers 3, __ feed winding on the shafts 2 is eliminated, as well as the influence of the weight of the feed monolith in the hopper on its quantity (fed to the unloading conveyor, which increases the uniformity of feed supply. Mounting the shafts 2 to the hopper 1 also contributes to increasing the uniformity of feed supply by means of spring shock absorbers 5, which provide a smoother grip of the feed by moving the shafts 2 40 in the vertical plane under the influence of the weight of the feed monolith.

Due to the fact that the axis of the shafts 2 are in the same plane as the wall of the hopper 45 located above it and in the latter, cuts are made for the fingers 3 to pass at the moment of their action on the feed, there is no tossing up and compaction of the feed in the vertical direction. In this case, dead zones at the side walls are eliminated and horizontal compression forces act on the feed “mass”, which improves the flowability of the feed mixture.

When dosing stems of various physical and mechanical properties, it is necessary to change the distance between the ends of the fingers 3 of the shafts 2. To do this, loosen the bolts 16 that fasten the shock absorbers 5 to the frame 13, and the bolts 17 in the wings 11 of the side walls. The shafts 9 with shock absorbers together with the lower part 9 of the side walls and the grill 4 move in the cuts, and thereby set the required distance.

The optimal distances between the ends of the fingers of the shafts when dispensing feed are

Silo, mm88

Haylage, mm38

Green mass, mm 30 Feed mixture, mm93

Uneven delivery,% b

The proposed dispenser-unloader of stalk feed allows you to evenly issue various types of stalk feed, i.e. It is more versatile than the well-known dispenser-unloader.

The side walls of the bunker are divided in height into three parts 7, 8 and 9. The upper part 7 of each wall is connected to the middle 8 by means of a clamp 10, and the lower part 9 of the wall overlaps the middle one by the height necessary so that during the movement of the shafts 2 there is no separation the walls, and is connected with it by the wings 11. The lower part 9 of the walls is connected with the grille by means of the hinge 12. On the frame 13, in the attachment points of the shock absorbers, slots 14 are made that allow the distance between the shafts 2 to vary. The shafts 2 move together with the grill 4 and the lower part 9 sidewalls. An unloading conveyor 15 is placed under the shafts 2. The drive to the shafts 2 is carried out via a cardan drive. The dispenser-unloader stalk feeds works as follows. The feed loaded into the bunker 1 is fed from it to the unloading conveyor 15 by means of rotating towards each other the shafts 2, provided with fingers 3, freely passing through the grooves of the grid 4 and slotted in the side walls. Due to the presence of the grids 4, which interact with the fingers 3, over the shafts 2, the winding of the feed on the shafts 2 is eliminated, as well as the effect of the weight of the monolith of the feed in the hopper on its quantity to the unloading conveyor, which increases the uniformity of the feed. The uniformity of the feed supply is also facilitated by fastening the shafts 2k to the hopper 1 by means of spring shock absorbers 5, which provide a smoother capture of the feed by moving the shafts 2 in the vertical plane under the weight of the monolith of the feed. Due to the fact that the axes of the shafts 2 are in the same plane as the wall of the bunker located above it and in the latter there are slots for the passage of the fingers 3; at the moment of their action on the feed, there is no throwing up and sealing of the feed in the vertical direction. This eliminates the dead zones at the side walls and the main effect on the feed mass is exerted by horizontal compressive forces, which improves the flowability of the feed mixture. When dosing different physico-mechanical properties of stalk feeds, it is necessary to change the distance between the ends of the fingers of the 3 shafts. 2. For this, bolts 16 securing the shock absorbers 5 to the frame 13 and bolts 17 in the wings 11 of the side walls are loosened. The shafts 9c with shock absorbers together with the lower part 9 of the side walls and the grill 4 move along the slots, and thus the required distance is established. The optimal distance between the ends of the shafts fingers when dispensing feeds is Silo, mm 88 Senazh, mm 38 Green mass, mm 30 Feed mixture, mm 93 Distribution unevenness,% b The proposed stem discharger dispenser allows you to evenly produce different types of stem feed, t . is more versatile than the known dispenser dispenser.
