Description

FIELD OF THE INVENTION The invention relates to working bodies of feed choppers used in agricultural production.

Known working body loader-grinder feed, including a cutter-drum, placed in the casing with a longitudinal cut on its front part 1.

The specified working body does not provide high quality grinding of feed due to the fact that it does not provide compression and grinding of feed particles directly in front of the cutter drum.

Also known working body loader-grinder feed, including a cutter-drum, placed in the casing with a longitudinal cut on its front part, above which is mounted with the possibility of rotation relative to the axis of the cutter-drum shield 2.

The disadvantage of this working body is that, like the first one, it does not ensure the forced retention of feed particles in a compressed form before grinding them with a milling drum. In addition, the milling drum is inserted into the monolith along the entire length, which increases the energy intensity of the process.

loading and reduces the quality of grinding feed.

The aim of the invention is to improve the process of separating the layer of feed from the monolith and improving the quality of their grinding. This is achieved by the fact that the working body is equipped with shafts fixed on the lower edges of the casing and shield with a set of vertical cutting discs and flat knives horizontally spaced between them, having oblique needle hooks and mounted on the shafts with the possibility of reciprocating movement in horizontal and vertical planes, while the rear parts of flat knives are placed directly at the edges of the cutter-drums.

In addition, the rear parts of the flat knives are attached hinged respectively to the casing and shield, with the upper flat knives springing relative to the shield.

Claims (2)

The working body is also provided with additional cutting discs located outside the casing at the ends of the shafts. The upper part of the casing is provided with a truncated cone-shaped nozzle with a rotary deflector attached to its smaller base. FIG. 1 schematically shows the working body of the loader-grinder of feed, top view; FIG. 2 is a view A of FIG. one; in fig. 3 - section bb FIG. 1. The working body includes a cutter-drum 1 with L-shaped knives, placed in the casing 2 with a longitudinal notch 3 on its front part, over which it is rotatably mounted by means of a hydraulic cylinder 4 relative to the axis of the cutter-drum 1 shield 5. On the lower edges the casing 2 and the flap 5 are shafts 6 with a set of vertical cutting discs 7, between which horizontally flat knives 8 are located, equipped with oblique needle hooks 9 and mounted on shafts 6 by means of Krivoshchips 10, sub-supports 11 and holders 12 with reciprocating movement in the horizontal and vertical planes. The rear parts of the knives 8 are placed directly at the blades of the cutter-drum knives and represent the contradictions connected by means of the hinges 13 respectively to the casing 2 and the shield 5, while the upper knives are connected to the shield using spring-absorbers 14. Outside the casing at the ends of the shaft 6 additional cutting discs 15 of increased size, preventing jamming of the working body in the monolith during operation. The milling drum 1 is driven from the hydraulic motor 16, and the shaft 6 is driven by chain drives 17 from the shaft of the milling drum. The upper part of the casing 2 is provided with a truncated cone-shaped nozzle 18 with a deflector 20 rotatable from the hydraulic cylinder 19. The loading and grinding of the feed by the working body is carried out as follows. The hydraulic cylinder 4 sets the required length of the longitudinal cut 3 on the front part of the casing 2 by turning the flap 5. Then, the tool is inserted into the monolith, while it is cut by the oscillating knives 8 to release a layer from it that is hooked to the cutting disks 7, cutting this layer on the feed bars. After that, the bars in a compressed form are fed to the cutter-drum 1. Under such conditions, the grinding of the mass of the cutter-drum occurs much more efficiently, more qualitatively and with less power consumption. Separated from the monolith and the ground mass is discharged through the deflector 20 into the vehicle. Claim 1. Worker body of a loader-crushed fodder, including a cutter-drum, placed in a casing with a longitudinal cut on its front part, above which a shield is installed with the possibility of rotation relative to the axis of the cutter-drum, in order to improve the separation process layer of feed from the monolith and increase the quality of their grinding, it is equipped with shafts fixed on the lower edges of the casing and shield with a set of vertical cutting discs and flat knives horizontally spaced between them, having oblique needle hooks and mounted on the shafts with the possibility of reciprocating movement in the horizontal and vertical planes, while the rear parts of the flat knives are placed directly at the edges of the cutter drum. 2. The body according to claim 1, characterized in that the rear parts of the flat knives are hinged respectively to the case and the shield. 3. The body according to claim 1, characterized in that the upper flat knives are spring-loaded relative to the shield. 4. The body according to claim 1., characterized in that it is provided with additional cutting disks located outside the casing at the ends of the shafts. 5. The body according to claim 1, characterized in that the upper part of the casing is provided with a truncated cone-shaped nozzle with a rotary deflector attached to the upper part of the casing provided with a truncated cone-shaped nozzle with a rotary deflector attached to its smaller base.
