Abstract

The invention relates to agriculture, in particular to devices for grinding and loading of coarse feed from coils on livestock farms. The purpose of the invention is to reduce energy consumption and improve the quality of grinding. Grinder-loader roughage contains a frame 1 with a hopper 2, chopping drums 11 with knives 12, feeding 9 and unloading 18 conveyors, drive. The feed conveyor 9 is equipped with a reverse mechanism and knives 12 placed on its outer surface. The grinding drums 11 are installed in parallel in a horizontal plane at the side walls of the hopper 2 and are equipped with a pressure regulator made in the form of a hingedly suspended and spring-loaded frame. The roll is placed on the feeding conveyor 9, which, moving, unwinds the roll and feeds the material to one of the chopping drums 11. The knives of the drums cut the material, and the conveyor 9 feeds it to the discharge conveyor 18. 1 Cp. .

ABOUT

This invention relates to agriculture, in particular to devices for shredding and loading roughage from coils on livestock farms.

The purpose of the invention is to reduce energy consumption and improve the quality of grinding.

The drawing shows a loader shredder for coarse feed.

Grinder-loader roughage consists of a frame 1 with a hopper 2, a vertical rack 3. The side walls of the bunker 2 are interconnected by sidewalls 4. On the side crossbars 5 of frame 1 and on the middle vertical rack 3 in bearings 6 shafts 7 are installed with asterisks 8. Grinding the working body is made up of two parts: the feed in the form of a chain-slatted conveyor 9 with plank-contradictions 10 and chopping drums 11 with knives 12. The drums 11 with the help of frames 13 are hingedly hung on the frame 1 with the possibility of turning surfaces of the chain-slat conveyor 9 and pressure control in the grinding zone of the material. To regulate the pressure, frame 13 is provided with a spring 14, which is mounted on a cable 15 with a stop 16. The outflow chambers 17 are located between the lower - descending branches of the chain-slat conveyor 9 and the hopper 2. Under the outflow chambers 17 there is a conveyor 18 for receiving the crushed mass and its transfer to the vehicle. Movement to the grinding tool and conveyors can be transmitted from an electric motor with a gearbox 19.

Grinder-loader works as follows.

A roll of hay with a pre-cut twine along a curvilinear section formed by the force of the roll weight on the upper branch of the chain-slat conveyor is carried upwards by the action of tangential forces from the conveyor slats. The roll, having made a reciprocating motion, unwinds, thereby releasing the tape of material. Depending on the initial position of the roll in the bunker, the tape of the hay-and-straw mass with the slat-contradictions 10 of the conveyor 9 can be brought to one of the drums 11 with knives 12. At the same time, the direction of rotation of the drive shaft the gearbox 19 must correspond to the feed of the tape material to the chopping drum. Reversal when changing the direction of rotation of the banks 11 and the drive shaft of the conveyor 9

can be carried out by any of the known methods depending on the type of energy source received. The amount of roll rolling depends on its radius, and the curvature

the curvilinear section is from the mass of the roll, therefore, with a decrease in its mass and radius, the stroke of the reciprocating movement increases, which contributes to a better formation of the tape. Tape

The hay-straw mass lying on the counter-strips 10 of the conveyor 9 and passing under the blades 12 of one of the drums 11 takes a position in which the blade of the knife cuts the ribbon between the strips-contradictions. The knives cut the tape layers in some arc with splitting and can take a position in which their blades come close to the striking strips. Quality

The cutting, as well as the resistance applied to the blade of the knife, depends on the forces of the tape spinning and the size of the installation gap between the blade of the knife and the stems through the thickness of the tape, are provided by adjusting the spring stiffness 14 and the stop 16 on the t 15. coordination of the drum and the slats of the conveyor belt. In cases of exclusion of crushing, the drums with knives must be turned so that the cut comes to the middle of the step between the laths.

When moving the crushed mass is its flow in the lower chamber 17,

and then to the conveyor 18. The latter carries out a continuous removal of the crushed mass into the vehicle. After shredding one roll, the loader-chopper is loaded into the hopper.

next roll.
