Description

Technical Field

[0001] The utility model belongs to the technical field of forage crushing, in particular to a forage crushing device for dairy cow breeding. Background Art

[0002] Dairy cows are mainly black and white cows. This breed has strong adaptability, a wide distribution range, high milk production, and tolerance to roughage. Some grass is used in dairy cow breeding, and grass processing can improve palatability, reduce feed waste, and increase storage time. Some grass with high crude fiber content or hard texture is generally crushed, and a crushing device is generally used for grass crushing.

[0003] The existing forage crushing device for dairy cattle breeding still has large-sized forage that does not meet the standards after crushing the forage, which needs to be manually screened and crushed again, wasting manpower and reducing utilization efficiency.

[0004] For example, a forage crushing device for dairy cattle farming (authorization announcement number CN215683500U) has a second rotating shaft and a first crushing roller, and a third rotating shaft and a second crushing roller disposed inside a housing. A first motor drives the second rotating shaft to rotate, and a linkage device is used to drive the third rotating shaft to rotate, thereby rotating the first and second crushing rollers. This device can crush the forage twice, pulverizing it more thoroughly and increasing the crushing effect of the device. However, this device has the problem of being unable to screen out larger forage for secondary processing, reducing its efficiency. Utility Model Content

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] During use, the dairy grass crushing device is controlled by a linear motor provided on a vertical side of the mounting frame to move the slide plate linearly, pressing against the movable box so that the movable box is pushed out of the mounting frame and positioned above the bottom plate. Subsequently, the screw threaded pin provided in the fixing groove is screwed, and the movable block is driven by the third telescopic rod at the top of the protective frame to move downward, so that the screw threaded groove on the side of the movable block is aligned with the screw threaded pin for fixing.

[0016] The third telescopic rod then controls the moving block, driving the moving box to move upward synchronously, aligning the mounting plate with the lowest end of the groove. The second telescopic rod, positioned in the mounting groove, controls the movement of the filter screen, causing larger grass that has not been screened out to move upward. The first telescopic rod, positioned on the side of the moving box, then controls the displacement of the push plate, pushing the larger grass into the crushing box through the groove. This facilitates secondary crushing of the larger grass, saving manpower, eliminating the need for manual screening and input, and improving efficiency. This forage crushing device for dairy cattle farming facilitates secondary crushing of larger grass, saving manpower, eliminating the need for manual screening and input, and improving efficiency.

The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0032] How it works

[0033] The grass crushing device for dairy cattle breeding adds raw materials through the feed hopper 31 and chops them with the cutting roller 30. After the grass is crushed, the grass that meets the size standard falls off through the leakage groove, and the grass of larger size remains on the surface of the filter screen 28. The linear motor 12 on the vertical side of the mounting frame 1 controls the slide 11 to move linearly, pressing against the moving box 4, so that the moving box 4 is pushed out of the mounting frame 1 and is located on the bottom plate 3. Then, the threaded nail 26 set in the fixing groove 27 is screwed, and the moving block 20 is driven by the third telescopic rod 18 at the top of the protection frame 22 to move downward. The moving block 20 is moved so that the thread groove 17 on the side of the moving block 20 is aligned with the threaded nail 26 for fixation. Then the third telescopic rod 18 controls the moving block 20 to drive the moving box 4 to move upward synchronously so that the mounting plate 29 is aligned with the lowest end of the groove 25. The second telescopic rod 14 arranged in the mounting groove 21 controls the filter screen 28 to move so that the larger-sized grass that has not been screened out is moved upward. Then the first telescopic rod 13 arranged on the side of the moving box 4 controls the push plate 15 to move, and the larger-sized grass is pushed into the crushing box 19 through the groove 25 for secondary processing.
