Description

Technical Field

[0001] The present invention relates to the technical field of grain crushers, and specifically to a new type of grain crusher for a silage machine. Background Art

[0002] The grain crusher of a silage machine is a device specifically designed for the processing of silage feed. It can effectively crush grains such as corn, wheat, and rice so as to better carry out silage fermentation.

[0003] In traditional grain crushers of silage machines, the transverse teeth on the surface of the wire rollers are usually horizontally distributed. During the crushing process, seeds may splash towards both ends of the crushing roller, thus hitting the outer shell frame and generating a large amount of noise.

[0004] Therefore, those skilled in the art have provided a new type of grain crusher for a silage machine to solve the problems raised in the above background art. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a new type of grain crusher for a silage machine. A main drive roller is rotatably arranged between a pair of first bearing seats, and a driving wire roller is installed at the outer end of the main drive roller. A secondary drive roller is rotatably arranged between a pair of second bearing seats, and a driven wire roller is installed at the outer end of the secondary drive roller. Transverse teeth are designed at the outer ends of both the driving wire roller and the driven wire roller. By designing the helical lines of the transverse teeth on the surfaces of the driving wire roller and the driven wire roller to be opposite to each other left and right, and the helical direction is towards the middle of the roller body. Therefore, when the driving wire roller and the driven wire roller cooperate to crush seeds, a force will be given to the seeds to move towards the middle of the roller body, thus avoiding the seeds from splashing towards both ends after being crushed and generating impact noise, and increasing the soft wire effect. This solves the problem that in traditional grain crushers of silage machines, the transverse teeth on the surface of the wire rollers are usually horizontally distributed, and during the crushing process, seeds may splash towards both ends of the crushing roller, thus hitting the outer shell frame and generating a large amount of noise.

A transmission belt is sleeved on the outer ends of the driving wheel, the first transmission wheel, the second transmission wheel, the third transmission wheel, and the fourth transmission wheel;

[0010] Through the above technical solution, when the driving wheel rotates clockwise, the first transmission wheel rotates clockwise through the transmission of the transmission belt, the second transmission wheel rotates counterclockwise, the third transmission wheel rotates clockwise, and the fourth transmission wheel rotates counterclockwise.

Both ends of the secondary drive roller are respectively designed in the middle of the two second bearings, which facilitates the rotation of the secondary drive roller.

[0013] Further, a discharge port is opened at the middle of the top of the outer shell frame, and a feed port is opened at the middle of the bottom of the outer shell frame;

[0014] Through the above technical solution, a discharge port is opened at the middle of the top of the outer shell frame, and a feed port is opened at the middle of the bottom of the outer shell frame, which facilitates the input and discharge of the seeds.

[0015] Furthermore, both the driving wire roller and the driven wire roller are made of steel alloy, and the surfaces of the driving wire roller and the driven wire roller are both coated with a supersonic tungsten carbide coating;
