Abstract

This invention relates to agricultural machinery industry and provides enhanced functionality of a shredder by providing additional crushing of feed supplies. The shredder includes a body 2 with an unloading window 3 to which the feed is moved by a longitudinal conveyor 4, beaters having knives 6 and a cross conveyor 7. For additional grinding of feed, the cutting unit is mounted under the unloading edge of the transverse conveyor 10 knife drum 8. When distributing sufficiently crushed feed overlying the discharge window flap 11 leans back, and the drum 8 is turned off. When distributing long-length feeds in loose form or in bales and rolls, the shield first overlaps the discharge port, forming the wall of the receiving opening through which the feed is fed to the drum 8 for additional grinding. Thereafter, the feeds 9 are sent to the rear part of the body by means of firewood 9, when fully filled, the flap opens again, ensuring distribution of regrind feed to the feeders. 5 il.

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to feed dispensers, m.

The purpose of the invention is to enhance the functionality of the shredder-feed feeder by providing additional grinding of the distributed feeds.

In Fig.1 schematically shows a feed feeder-grinder, a general view; FIG. 2 is the same, section A-A in FIG. one; on fig.Z - the same, section B - B on figure 1; figure 4 - cutting apparatus with additional grinding of feed, cross section; Figure 5 - the same, in the off position.

The shredder includes a body 2 mounted on the undercarriage 1 with a discharge window 3, a longitudinal bottom conveyor 4, a rotary feed separator block, made in the form of a beater 5 having knives 6, and a cross conveyor 7. Under the discharge edge of the latter, there is a cutting device the drum 8. on the shaft of which the firewood 9 is fixed. The drum 8 and the joint 9 are installed in the casing 10 open at the top. In the zone of the discharge window there is a folding curtain shaped deflector 11 of the curtain. The drive of all working bodies is carried out from the tractor VOM through a cardan transmission of 12 s.

the ability to disable the cutting apparatus.

The firewood 9 is fitted with a feed pipe 13 fixedly mounted on the casing 10 and a distribution air pipe 14 with a hinge 15 hingedly fixed. There is a deflector 15 on each of these lines.

The flap 11 has two positions. In the first position (Fig. 4), the flap closes the discharge port 3, the abutment to the outer end of the casing 10 and, with its lower part, forms the wall of the receiving opening 18 for loading the cutting apparatus. In the second position (Fig. 5), the flap rises to the top or is retracted to the side, tilting the discharge port, as a result, the feed from the cross conveyor to the feeders 19 is unhindered.

Feed chopper works as follows.

When distributing sufficiently crushed feeds laid in layers in body 2, the cutter drum 8 of the cutting unit is turned off, and the flap 11 is set to the position corresponding to the open unloading window 3. The feed is fed by the longitudinal conveyor 4 to the beaters 5, which are thrown over the transverse conveyor 7, and then , mine the knife drum 8, through the discharge window enter the feeders 19 (figure 5).

When dispensing with large doses of long-stalked feed stacked in a body in loose form or in bales and rolls, the shield 11 initially covers the discharge window (figure 4), forming the wall of the receiving opening 18, through which the pre-crushed 6 tines 5 for particles long Approximately 150 mm of feed is fed to the cutter drum 8 of the cutting unit for additional grinding. In the process of additional grinding, the feed is moved in the axial direction to the firewood 9 and further along the pneumatic line 14 is sent to the rear part of the body, freed from the pre-loaded feed. When this valve 16 of the pneumatic line 13 is closed, and the valve 17 of the pneumatic line 14 is open. Additional grinding is carried out

until all feeds loaded into the body have been ground into smaller particles. After that, the grinding of the feed is distributed to the feeders, tilting the flap 11 and opening the discharge window

(figure 5).

When distributed in small doses of long-stemmed feeds laid in a body in a loose form, or in bales or rolls, the process of their grinding and distribution is carried out simultaneously. For this, flap 11 overlaps the discharge window (Fig. 4) and the necessary distribution rate is established, not exceeding the throughput capacity of the additional grinding stage. The valve 17 overlap the pneumatic pipe 14, and the valve 16 is opened, providing movement of the feed through the pneumatic line 13 (figure 2). When the feed dispenser is working, the chopper feeds during its movement, twice

crushing, firewood is fed through pneumatic line 13 immediately to feeders 19.

Claims (1)

Claims of the invention Feed chopper, containing longitudinal and transverse conveyors placed in the body with the discharge window, between which a block of rotary feeders fitted with knives is installed, and firewood with an air distribution pipe that differs from that. that, in order to expand its functionality by providing additional crushing of the distributed feed, it is provided with a cutting device located under the discharge edge of the cross conveyor, having a casing open at the top, and a folding curved shield covering the unloading window of the body, which is mounted with the possibility of joining the outer end of the casing with the formation of the wall of the receiving opening for loading the cutting apparatus.
