Abstract

The invention relates to agricultural machinery and can be used for grinding vegetable feed in self-propelled combines and stationary plants. The purpose of the invention is to reduce the energy intensity of the grinding process and increase the convenience of adjusting the gap in the cutting pair. The shredder contains a drum grinder with knives 1, a triangular cross section element 2, mounted in submill 3, in the movable part 12 having a groove 6. The anti-cutting element 2 is equipped on both sides with clamps 7, on whose shoulders the adjusting screws 8 and 9 rotate the brackets 10 of the housing 11. The feed rollers 4 and 5 feed the mass onto the shear member 2, where it is cut by the knives 1. At the same time, an expanding gap is formed between the side edges of the shear member, the brass and the knives, which excludes dragging a mass and reduces the cutting resistance. The gap in the cutting pair is adjusted by screws 8 and 9, the shanks of which are moved to a convenient area for operation. 2 Il.

Description

; The invention relates to the sep- a: domestic mechanical engineering and can be used for grinding feeds in field and stationary conditions.

The purpose of the invention is to reduce the energy consumption of the process of grinding the plant mass and the laboriousness of adjusting the gap in the cutting pair.

FIG. 1 shows a grinding apparatus; in fig. 2 is a diagram of adjusting the gap in the cutting pair.

The proposed grinding apparatus contains a drum with cutting knives 1, a shear bar 2 mounted on a brackerel 3, and a lower 4 and upper 5 feed rollers feeding the grinded mass to the cutting zone. Along the length of the bushes 3, the groove 6 is made, and the beam 2 has the shape of an equilateral triangle in cross section, with one of the timber edges being installed in the slot; The ends of the shearing bar are equipped with clamps 7. Adjusting 1 bars 8 and 9 are supported on the shoulders of the clamps, the lower threaded ends of which are screwed into the threaded

The bushings of the arm 10 of the side body of the grinding apparatus 11, and the upper ends have shanks for rotating the rods.

The under-bristle consists of two parts fixed and mobile 12. The movable part 12 is made in the form of a cylindrical hinge and can be rotated relatively motionlessly on the side of the red cowling 3. The anti-cutting element of the triangular section is mounted with one edge in the groove 13 of the movable part 12.

The grinding apparatus operates as follows.

The ground mass is fed by the lower 4 and upper 5 feed rollers.

on the cutter bar 2 and is ground with the knives of the drum 1.

When installing or reinstalling. the bar that is necessary to rotate the shanks of the rods B and 9, brought outside to the area accessible for work, loosen the pressure of the rods on the clamps 7 of the beam 2 and remove the counter bar. The installation is performed in reverse order.

To adjust the gap, it is necessary to rotate the rods in opposite directions in the cutting pair. In order to reduce the gap between the bar 2 and the knife 1 from the value O to the value fi, the pressure of the rods 8 on the clamps 7 should be loosened and the clamps pressed by the rods 9. The bar 2 will turn in the groove 6 by the angle oi.

Dp increase the gap from the value of O to the value of Og should loosen the pressure of the rod 9 and tighten the rod 8.

When adjusting the gap, the movable part 12 of the pillow along with the beam 2 rotates relative to the stationary under-boring 3. This ensures a more even distribution of pressure on the under-boring, smaller deformations of the contacting surfaces and smooth movement of the beam.

Adjusting the clearance distance between the cutter bar 2 and bushel 3 facilitates access to the adjusting elements of the grinding apparatus, which are placed in the upper zone of the grinder, and provides the possibility of operative control over the clamping force of the beam.

The anti-cutting bar of a triangular cross section provides a constant gap D between the drum grinding unit and the lateral edges of the components of the cutting device, and this gap several times exceeds the working gap in the cutting pair 5, or H, which eliminates or significantly
