Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

Example 1

As shown in Figures 1 to 3, a shredder includes a motor 3, a hydraulic controller 4, an oil pump motor 5, a debugging platform 8, a box body 10, and a shredding space 11 arranged inside the box body. The shredding space 11 The casing 10 above is provided with a feed port 7, and the shredding space 11 is provided with a discharge port 9 below, and one side of the shredding space 11 is provided with a front push plate 101, and the front push plate 101 is connected with a first Oil cylinder 1, the first oil cylinder 1 includes a first cylinder body 102 and a first piston rod 103, the end of the first piston rod 10 is connected with the front push plate 101, and the other side of the shredding space is provided with Back push plate 61, described back push plate 61 is connected second oil cylinder 6, and described second oil cylinder 6 comprises second cylinder block 62 and second piston rod 63, and the end of described second piston rod 63 is connected with back push plate 61 connection, the shredding space 11 is provided with a cutter roller 2, and the cutter roller 2 is driven to rotate through the motor 3 to control the transmission mechanism, and the transmission mechanism includes a drive wheel 31 fixedly connected to the motor rotation shaft, and a connection The driven wheel 21 on the knife roller 2, the driving wheel 31 and the driven wheel 21 are connected by a conveyor belt 32, the hydraulic controller 4 is arranged at the bottom of the box body 10 and is adjacent to the motor 3, the hydraulic controller 4 4 is connected with the first oil cylinder 1 and the second oil cylinder 6 through a hydraulic pipe, one end of the hydraulic pipe is connected with the oil pump motor 6, and a debugging platform 8 is provided on one side of the box.

The blades 22 are arranged on the side of the knife roller 2, and the blades 22 are arranged in a spiral shape along the circumference of the knife roller 2. When the blades 22 are arranged in a spiral shape, the material is only at the same point every time the knife roller 2 rotates one week. Once cut by the blade 22, the force is relatively uniform when the material is shredded, which can ensure that the pulverized material has a uniform size after the material is crushed.

When the utility model shredder is in use, the material enters the shredding space from the feed port 7, and the material is bounced forward by the counterclockwise high-speed rotating knife roller 2 to push the space where the plate 101 is located, and the hydraulic controller 4 controls the oil pump motor 5 to work , the hydraulic oil is sent to the first oil cylinder 1 through the hydraulic pipe, so that the hydraulic pressure in the first oil cylinder 1 is increased, and the front push plate 101 is pushed forward, and the front push plate 101 pushes the material to the knife roller 2 from one side, and The material is clamped with the knife roller 2, so that the knife roller 2 can cut the material more efficiently.
