[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] 1. The structure and function of the traditional grass blender for breeding are relatively simple. It realizes the feeding step through a feeding hopper, but the feeding hopper on the device cannot control the speed of material feeding, which reduces the application scope of the equipment; if the device needs to crush crop raw materials such as rice straw, wheat straw, and reed grass into powder, the user can pass the raw materials into the mixing tank assembly through the feeding assembly. The user uses the first feeding box assembly, and the operator can drive the second motor forward or reverse. The second motor drives the long rotating rod and the gear to rotate forward or reverse. The gear will drive the sliding plate meshed on one side to slide horizontally left and right inside the feeding cavity box. At this time, the relative position of the through groove and the bottom opening of the feeding hopper changes. The purpose of this operation is to control the material speed of the feeding hopper feeding into the mixing tank assembly. The larger the exposed area of ​​the bottom opening of the feeding hopper, the faster the material feeding speed. If the exposed area of ​​the bottom opening of the feeding hopper is, the slower the material feeding speed is. This setting is convenient for users to control and adjust the speed of crop raw materials entering the device by setting the feeding box assembly on the top surface of the device;

[0018] 2. After the operator passes the raw materials into the inner cavity of the mixing tank assembly through the feed box assembly, the user can turn on the first motor, the first motor rotates to drive the long rod to rotate, the long rod drives the first bevel gear and the second bevel gear to rotate, and the second bevel gear drives the rotating rod, the screening plate, the connecting rod and the crushing plate to rotate. This setting integrates the crushing and mixing functions of the crop raw materials. This operation improves the working efficiency of the device, is fully automated, and saves manpower and material resources;

[0019] 3. The materials put into the mixing tank assembly are crushed by the high-speed rotating crushing disk in advance. The crushed materials will fall on the top surface of the screening disk. The leakage holes on the screening disk will screen the crushed materials. The materials screened by the screening disk will enter the bottom cavity of the mixing tank assembly. At this time, multiple groups of rotating stirring plates will evenly mix the crushed mixed materials until the materials are evenly mixed.

[0020] 4. The materials that have not passed through the screening plate in the device will continue to be crushed above the screening plate through the crushing plate until they pass through the screening plate and enter the mixing chamber after crushing, thus improving the uniformity of the food efficiency of the equipment;

[0021] 5. The device can avoid blockage due to excessive materials through the feeding component, thus improving the practicality of the device. Finally, the evenly mixed and crushed agricultural materials leave the mixing tank component through the discharge component and are provided to cattle for consumption. The crushing and stirring functions of agricultural raw materials are integrated. This operation improves the working efficiency of the device and is fully automated. The fully crushed and evenly crushed materials are conducive to livestock digestion and absorption, thus improving the practicality of the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Working principle: The utility model discloses a grass mixer for beef cattle breeding. The structure and function of the traditional grass mixer for breeding are relatively simple. The feeding step is realized by a feeding hopper. However, the feeding hopper on the device cannot control the speed of material feeding, which reduces the application scope of the equipment. If the device needs to grind crop raw materials such as rice straw, wheat straw, and reed grass into powder, the user can pass the raw materials into the mixing tank component 1 through the feeding component. The user uses the first feeding box component 2, and the operator can drive the second motor 23 in the forward or reverse direction. The second motor 23 drives the long rotating rod 24 and the gear 25 to rotate in the forward or reverse direction. The gear 25 will drive the sliding plate 27 meshing on one side thereof to move horizontally to the left inside the feeding chamber box 21. Slide right, the through slot 28 matches the size of the bottom opening of the feed hopper 22, and the top surface of the sliding plate 27 moves horizontally left and right close to the bottom opening of the feed hopper 22. At this time, the relative position of the through slot 28 and the bottom opening of the feed hopper 22 changes. The purpose of this operation is to control the material speed of the feed hopper 22 feeding into the mixing tank assembly 1. If the exposed area of ​​the bottom opening of the feed hopper 22 is larger, the material feeding speed is faster. If the exposed area of ​​the bottom opening of the feed hopper 22 is smaller, the material unloading speed is slower. This setting is convenient for users to control and adjust the speed of crop raw materials entering the device by arranging a feed box assembly on the top surface of the device, avoiding the situation where the feed port of the device is blocked due to excessive materials, thereby improving the practicality of the device;

[0039] After the operator passes the raw material into the inner cavity of the mixing tank assembly 1 through the feed box assembly, the user can turn on the first motor 13, the first motor 13 rotates to drive the long rod 19 to rotate, the long rod 19 drives the first bevel gear 191 and the second bevel gear 192 to rotate, the second bevel gear 192 drives the rotating rod 17, the screening plate 16, the connecting rod 15 and the crushing plate 14 to rotate, the material put into the mixing tank assembly 1 is crushed in advance by the high-speed rotating crushing plate 14, the crushed material will fall on the top surface of the screening plate 16, the leakage hole groove on the screening plate 16 will screen the crushed material, and the material screened by the screening plate 16 will enter the bottom of the mixing tank assembly 1 The material that has not passed through the screening plate 16 will continue to be crushed above the screening plate 16 and continuously crushed by the crushing plate 14 until it passes through the screening plate 16 and enters the mixing chamber after being crushed. Finally, the evenly mixed crop material leaves the mixing tank assembly 1 through the discharge assembly 5 and is provided to the cattle for consumption. This arrangement integrates the crushing and stirring functions of the crop raw materials. This operation improves the working efficiency of the device, is fully automated, saves manpower and material resources, and the fully crushed and evenly mixed materials are conducive to the digestion and absorption of livestock, thereby improving the practicality of the entire device.

[0042] Working principle: When the user uses the second feed box assembly 3, the user can turn on the automatic telescopic rod 33, and the automatic telescopic rod 33 moves to extend or retract. The automatic telescopic rod 33 drives the movable plate 32 inside the second feed box assembly 3 to slide horizontally left and right, and the limit block 35 slides on the periphery of the limit rod 34. At this time, the top surface of the movable plate 32 is close to the bottom opening surface of the feed hopper 31 and moves horizontally left and right.
