DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1 , a forage crushing device for animal husbandry comprises a crushing box 1, a driving motor 2 and a supporting frame 3. The bottom end of the crushing box 1 is fixedly mounted on the supporting frame 3, a feeding port 4 is fixed at the bottom end of the crushing box 1, a processing box 6 is fixed on the top of the crushing box 1, and a feeding port 5 is fixed on the top of the processing box 6. A receiving roller 8 is symmetrically arranged on the top of the processing box 6, and rotating rods 9 are fixed at both ends of the receiving roller 8. The rotating rods 9 on both sides are rotatably connected to the side walls of the processing box 6 through bearings. Two rotating rods 9 on one side are both penetrated to the outside of the processing box 6 and a gear 12 is fixed thereto. The two gears 12 are meshed with each other. A driven wheel 10 is also fixed on the rotating rod 9 in one of the gears 12. Another driven wheel 10 is fixed on the output shaft of the driving motor 2. The two driven wheels 10 are connected by a transmission belt 11. A pre-processing structure is arranged at the bottom end of the receiving roller 8. The receiving roller 8 is used for extrusion and feeding, so as to avoid the problem of low crushing efficiency on each side caused by drying and swelling of the forage grass, and at the same time, the feeding speed of the crushing device is greatly improved.

[0022] Specifically, a guide plate 7 is fixed inside the processing box 6 above the two receiving rollers 8. The two guide plates 7 are arranged to be relatively open arcs. The opposite sides of the two guide plates 7 are located on the same vertical plane as the center of the receiving rollers 8. The guide plates 7 are used for guiding, so that the grass can slide between the two receiving rollers 8. The diameter of each receiving roller 8 is less than half of the internal length of the processing box 6. The length between the centers of the two receiving rollers 8 is greater than the diameter of the receiving rollers 8, so as to ensure that a gap is left between the two receiving rollers 8, so that the grass can move toward the cutting blade 16 under the drive of the receiving rollers 8, thereby facilitating the pre-cutting of the cutting blade 16.

[0023] As an optimization solution, Figure 3 and Figure 4As shown, the pre-processing structure includes a cutting plate 13, a rotating roller 15 and a cutting blade 16. The cutting plate 13 is fixed on the inner wall of the processing box 6 on one side of the bottom end of the receiving roller 8, and a rotating roller 15 is arranged inside the processing box 6 on the side of the cutting plate 13, and another rotating rod 9 is fixed at both ends of the rotating roller 15. The two other rotating rods 9 are rotatably connected to the side wall of the processing box 6 through bearings. One side of the other rotating rod 9 extends to the outside of the processing box 6 and is fixed with a gear 2 17, and the gear 2 17 is meshed with the gear 1 12. A number of cutting blades 16 are equidistantly fixed on the outer surface of the rotating roller 15. By pre-cutting with the cutting blade 16, longer forage grass can be cut into shorter ones, which is convenient for subsequent crushing and avoids the forage grass being entangled on the crushing roller during crushing.

[0024] Specifically, the diameter of the other rotating rod 9 is smaller than the outer ring diameter of the driven wheel 10, and the end of each rotating rod 9 extending to the outside of the processing box 6 is set to a horizontally placed "T" shape to prevent the other rotating rod 9 from affecting the normal transmission of the transmission belt 11; the top of the cutting plate 13 is set to an arc that matches the receiving roller 8, and the height of the cutting plate 13 is greater than the sum of the heights of the rotating roller 15 and the two cutting blades 16, which is convenient for the top of the cutting plate 13 to fit with the receiving roller 8, and convenient for the cutting blade 16 to rotate close to the cutting plate 13 to cut the forage pieces; a limiting plate 14 is fixed on the inner wall of the processing box 6 between the rotating roller 15 and the receiving roller 8, and the limiting plate 14 is set to an arc that matches the receiving roller 8 and the outer end of the cutting blade 16, and is guided by the limiting plate 14 to facilitate the movement of the forage between the cutting plate 13 and the cutting blade 16.

[0025] Working principle: when the forage grass needs to be crushed, the forage grass is put into the feed port 5, and the driving motor 2 is turned on, so that the driving motor 2 runs to drive the driven wheel 10 to rotate, and the driven wheel 10 on the receiving roller 8 can be driven to rotate through the transmission belt 11, and the driven wheel 10 drives the rotating rod 9 to rotate when the driven wheel 10 rotates, and the rotating rod 9 drives the two mutually meshing gears 12 to rotate when the rotating rod 9 rotates, and the two receiving rollers 8 can be driven to rotate relative to each other, so that the forage grass inside the feed port 5 is gathered and pulled into the feed port 5, and at the same time, the gear 12 drives the gear 2 17 to rotate, and the gear 2 17 drives the rotating roller 15 to rotate when the gear 2 17 rotates, and the rotating roller 15 drives the cutting blade 16 to rotate to cut the forage grass, and the divided forage grass falls into the crushing box 1 for crushing.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
