Reciprocating shearing type straw rubbing filament and kneading machine

Abstract

The invention relates to a processing mechanical device for longitudinal shearing, filament and kneading of coarse straight straw such as corn and pennisetum hydridum. The processing mechanical device is a reciprocating shearing type straw rubbing machine and includes a feeding swing mechanism, a shearing rubbing mechanism and a moving cutter driving mechanism. The feeding swing mechanism includes a skewing driving mechanism and a swinging trough, and the skewing driving mechanism drives the swinging trough to move; the shearing rubbing mechanism is composed of a moving cutter component and a fixed cutter component, the moving cutter component is driven by the moving cutter driving mechanism to do reciprocating motion and cooperate with the fixed cutter component and the swinging trough, straw materials are merged in a shearing zone to complete filament and kneading, the processed straw materials can form high-quality soft filaments, and the palatability of livestock straw feed is greatly improved.

Description

[0001] Technical field [0002] The invention belongs to the technical field of agricultural machinery, and relates to a feed processing mechanical device which longitudinally cuts thick and straight crop straws such as corn straws and emperor bamboo grass, and forms them into a flexible silk shape. Background technique [0003] The currently known straw kneading machine, such as the straw kneading machine (CN02281448), uses the hammer blade on the rotor assembly to cooperate with the fixed knife to cut the straw longitudinally; The cutting blade roller is used to cooperate with multiple fence components to cut the straw longitudinally. The structures of the two methods are that the hammers or blades are arranged at intervals along the axial direction of the rotor, and the shearing is carried out in cooperation with the fixed knife. The straw is input and sheared along the radial direction of the rotor, and the straw silk cannot be achieved at one time to achieve the desired ...

Problems solved by technology

[0005] The rotor assembly and the cutting blade roller of the above two shearing devices with similar structures adopt a single-direction 360-degree rotation mode, and the long and thick straw that cannot be cut off is driven by the hammer or the blade, and is wound around in the direction of rotation. On the rotor assembly and the cutting blade roller, the hammer blade or the blade is surrounded by straw and forms an integral body with the rotor and loses its effect; the rotor is locked due to the huge frictional resistance generated by the straw winding and accumulation to a certain extent with the fixed knife or rack on the inner wall of the working chamber. move, causing the machine to jam

[0006] The fence-type straw kneading machine solves the problem of straw winding around the cutting blade roller through the fence assembly with the function of fixed knife and combing function, but all the cut straw needs to be filtered out through the gap screen formed by the fence assembly. The melting and kneading effects are excellent, but the slender filaments formed in it will continue to hang on the edges of the fixed knives in the fence assembly. Since the cutting blade roller rotates and cuts in 360 degrees in one direction, the moving knife When passing through the gap, it cannot be cut or discharged, so that the gap is gradually narrowed due to the occupation of filaments, and the subsequent material continues to accumulate and cannot be removed in time. When the gap is completely blocked, the moving blade is unable to overcome its strong resistance to pass through, resulting in jamming. machine
