[0019] In the present case, the feed pipe 11 is arranged on the top surface of the processing box 1 and is communicated with the crushing box 2. By connecting an elevator to the outside of the processing box 1, the elevator belongs to the prior art and is not shown in the attached drawings. The livestock hay is introduced into the feed pipe 11 through the elevator. During the process of the livestock hay falling from the feed pipe 11, it can be cut by the cutting mechanism first to pre-treat the livestock hay. The livestock hay cut by the cutting mechanism will slide downward. At this time, the cut livestock hay is conveniently guided toward the crushing mechanism through the guiding mechanism. At this time, the crushing mechanisms are staggered with each other and equidistantly arranged along the inner edge of the crushing box 2. The livestock hay guided to the crushing mechanisms can be crushed by the crushing mechanism. The livestock hay crushed by the crushing mechanism will fall down and be guided to the powder.

A rotating connecting rod 32 is rotatably arranged on the inner wall of the rotating tube 3, and a power motor for driving the rotating connecting rod 32 to rotate is fixedly arranged at the bottom end of the inner wall of the rotating tube 3.

[0022] The cutting mechanism includes a third rotating rod 7, a fourth bevel gear 71, a sleeve rod 72 and a crushing knife 721. One end of the third rotating rod 7 is inserted into the rotating tube 3 and fixedly connected with the fourth bevel gear 71. The third rotating rod 7 is rotatably connected to the rotating tube 3. The fourth bevel gear 71 is meshed with the second bevel gear 321. The second bevel gear 321 is fixedly connected to the periphery of the rotating connecting rod 32. A limit block 722 is rotatably set at the other end of the third rotating rod 7. A slide rail 25 for the limit block 722 to rotate is fixedly set at the top of the inner wall of the crushing box 2. The periphery of the third rotating rod 7 is fixedly connected to the sleeve rod 72. The crushing knife 721 is fixedly set at the periphery of the sleeve rod 72. The crushing knife 721 is equidistantly set along the circumference of the sleeve rod 72.

[0023] The starting of the rotating motor 111 can drive the rotating tube 3 to rotate, and the rotating tube 3 drives the third rotating rod 7 to rotate along the inner wall of the crushing box 2, thereby driving the sleeve rod 72 and the crushing knife 721 to rotate, and then the starting of the power motor can drive the rotating connecting rod 32 to rotate, and the rotating connecting rod 32 drives the second bevel gear 321 to rotate, and the second bevel gear 321 is meshed and connected with the fourth bevel gear 71, so that the rotation of the second bevel gear 321 can drive the fourth bevel gear 71 to rotate, and the fourth bevel gear 71 drives the third rotating rod 7 to rotate by itself, and the third rotating rod 7 drives the sleeve rod 72 to rotate, and the sleeve rod 72 drives the crushing knife 721 to rotate. Through the rotation and self-rotation of the crushing knife 721, the livestock hay in the falling process can be effectively cut and crushed.

[0024] The crushing mechanism includes a first rotating rod 23, a first connecting rod 231, a first crushing cutter 232 and a circular gear 233. The circular gear 233 is rotatably arranged at the top end of the inner wall of the crushing box 2. There are multiple groups of circular gears 233, and the adjacent ones are meshed and connected. The inner wall of the crushing box 2 is located below the circular gear 233 and is fixedly connected with a baffle 24. The top end of the first rotating rod 23 passes through the baffle 24 and is fixedly connected to the circular gear 233. The baffle 24 is rotatably connected to the first rotating rod 23. The first crushing cutter 232 is spirally wound and fixedly arranged on the periphery of the first rotating rod 23. The first crushing cutters 232 are staggered between adjacent ones. The bottom end of the first rotating rod 23 passes through the crushing box 2 and is fixedly connected to the first connecting rod 231. A belt 311 is sleeved on the periphery of the first connecting rod 231 and the connecting guide rod 31.

[0025] The circular gears 233 are all rotatably arranged on the top of the inner wall of the crushing box 2, and there are multiple groups of them. The first rotating rod 23 is fixedly arranged at the bottom end of the circular gear 233, and the bottom end of the first rotating rod 23 is rotatably arranged at the bottom end of the inner wall of the crushing box 2. One group of the bottom ends of the first rotating rod 23 penetrates the crushing box 2 and is fixedly connected to the first connecting rod 231. By arranging a belt 311 between the first connecting rod 231 and the connecting guide rod 31, the synchronous rotation of the first connecting rod 231 and the connecting guide rod 31 can be achieved. The bottom end of the rotating tube 3 is fixedly connected to the connecting guide rod 31, so the rotation of the rotating tube 3 can drive the connecting guide rod 31 to rotate, and the connecting guide rod 31 drives the belt 311 to rotate, thereby driving the first connecting rod 231 to rotate, the first connecting rod 231 drives the first rotating rod 23 to rotate, and the first rotating rod 23 drives the circular gear 233 and the first crushing cutter 232 to rotate. The wheels 233 are meshed and connected with each other, so that multiple sets of circular gears 233 can rotate at the same time, thereby enabling the first crushing cutter 232 to rotate. The first crushing cutters 232 are staggered between each other, so that the first crushing cutters 232 surround the inner edge of the crushing box 2. The livestock hay will pass between the first crushing cutters 232 during the downward flow. At this time, the livestock hay can be effectively crushed by the first crushing cutter 232. The crushed livestock hay will move downward to the bottom of the inner wall of the crushing box 2. The first crushing cutters 232 are staggered and rotated between each other at the inner edge of the crushing box 2. Therefore, the livestock hay that has not passed between the first crushing cutters 232 will still pass between the first crushing cutters 232 and then be discharged from the discharge hole 21. Therefore, it can ensure that the livestock hay is crushed in all directions, and the livestock hay is crushed in a sliding state, thereby improving efficiency.

[0026] A fixing plate 22 sleeved on the outer periphery of the belt 311 is fixedly connected to the bottom end of the crushing box 2 , and the fixing plate 22 is rotatably connected to the connecting guide rod 31 .

[0027] The fixed plate 22 is provided to protect the belt 311 and prevent the hay from being attached to the belt 311 during the process of crushing the hay, so as to prevent the transmission efficiency of the belt 311 from being affected.
