[0020] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] As Figures 1 to 3 shown, a crushing bin 2 is provided inside the equipment housing 1. An outlet 4 is provided at the bottom of the crushing bin 2. Two symmetrically distributed crushing rollers 5 are rotatably installed inside the crushing bin 2. Crushing cutters 6 are fixedly installed on the outer sides of the two crushing rollers 5. The crushing cutters 6 on the outer sides of the two crushing rollers 5 are distributed at intervals. A plurality of buffer rods 7 are slidably inserted into the inner wall of the crushing bin 2. A positioning spring 8 is fixed between one end of the buffer rod 7 and the equipment housing 1. The other end of the buffer rod 7 is inserted between two adjacent crushing cutters 6 on the outer side of the same crushing roller 5, and the end face of the buffer rod 7 is in contact with the outer surface of the crushing roller 5. Cleaning brush plates 9 are provided on both sides of the end of the buffer rod 7 located between two adjacent crushing cutters 6. The cleaning brush plates 9 are in contact with the crushing cutters 6. By using the cleaning brush plates 9 that are in contact with the sides of the crushing cutters 6, the crushing cutters 6 are cleaned when the crushing cutters 6 rotate with the crushing rollers 5, preventing the crushed feed from adhering and solidifying on the sides of the crushing cutters 6, which may cause a reduction in the crushing efficiency of the crushing cutters 6.

[0022] In this embodiment, a pressing plate 11 is fixed to the side of the cleaning brush plate 9 facing the buffer rod 7. The pressing plate 11 is slidably inserted on the side of the buffer rod 7. A plurality of pressing springs 10 are fixedly installed between the pressing plate 11 and the buffer rod 7. The pressing springs 10 are in a compressed state. The pressing springs 10 in the compressed state press the pressing plate 11 and the cleaning brush plate 9 towards the crushing cutter 6 direction, increasing the contact surface and friction force between the cleaning brush plate 9 and the crushing cutter 6, and better cleaning the crushing cutter 6.

[0023] As a preferred technical solution of this embodiment, as Figure 4 shown, a crushing main shaft 15 is fixedly inserted through the middle of the two crushing rollers 5. Both ends of the crushing main shaft 15 are inserted into the inside of the equipment housing 1 and are rotatably connected to the equipment housing 1. A detachable end plate 3 is detachably installed at one end of the equipment housing 1. A crushing motor 12 is fixed inside the end of the equipment housing 1 where the detachable end plate 3 is installed. A crushing gear 13 is fixed to the output shaft end of the crushing motor 12. Transmission gears 14 are fixedly installed on the outer sides of the two ends of the two crushing main shafts 15 close to the crushing motor 12. The two transmission gears 14 are meshed with each other. The crushing gear 13 is meshed with one of the transmission gears 14. By driving the crushing gear 13 to rotate through the crushing motor 12, the two meshed transmission gears 14 rotate towards each other, so that the two crushing rollers 5 drive the crushing cutters 6 to rotate towards each other, and the feed raw materials entering the crushing bin 2 are crushed.

[0024] Working principle: First, turn on the power supply of the device. After the power supply is turned on, the crushing motor 12 is energized and starts to drive the crushing gear 13 to rotate. The crushing gear 13 drives the transmission gear 14 that meshes directly with it to rotate, causing this transmission gear 14 to drive another transmission gear 14 to rotate. At this time, the two transmission gears 14 rotate towards each other. The two crushing rollers 5 rotate towards each other simultaneously driven by the two transmission gears 14. Then, the feed raw material to be crushed is added to the crushing chamber 2 from the top of the crushing chamber 2. The feed will gather between the two crushing rollers 5 due to the two crushing rollers 5 rotating towards each other. The rotating crushing rollers 5 use the crushing cutters 6 to crush the feed raw material. The crushed feed raw material leaves the crushing chamber 2 from the discharge port 4. During the process of the crushing cutters 6 crushing the feed, the compression spring 10 always applies a pressure to the pressure plate 11 and the cleaning brush plate 9 towards the side of the crushing cutters 6, causing the cleaning brush plate 9 to fit against the side of the rotating crushing cutters 6. When the feed attached to the outer surface of the crushing cutters 6 passes through the cleaning brush plate 9 during rotation, it falls off from the outer surface of the crushing cutters 6, realizing the cleaning of the feed attached to the outer surface of the crushing cutters 6 and avoiding the crushed feed from adhering and solidifying on the side of the crushing cutters 6, resulting in a reduction in the crushing efficiency of the crushing cutters 6.

[0025] The above has described the embodiments of the present utility model in detail in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
