[0020] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] The following will clearly and completely describe the technical solutions of the present utility model in combination with specific embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] See Figure 1 and Figure 2, the present utility model provides a horizontal single-shaft shredder, comprising:

[0023] a metal chain plate conveyor 1, a belt conveyor 2 and a shredding mechanism;

[0024] The shredding mechanism includes a shredding body, a front upper feeding roller 3, a rear upper feeding roller 4, a lower feeding roller 5 and a shredding machine knife roller 6. The lower feeding roller 5 and the shredding machine knife roller 6 are both rotatably installed on the shredding body.

[0025] It should be noted that the front upper feeding roller 3 and the rear upper feeding roller 4 are connected by sprockets and chains, and the rear upper feeding roller 4, the lower feeding roller 5 and the shredding machine knife roller 6 are all driven by a motor and a reducer in cooperation.

[0026] Specifically, a hydraulic cylinder is fixedly arranged on the shredding body, and an opening and closing housing 7 is fixedly arranged on the hydraulic rod of the hydraulic cylinder. The front upper feeding roller 3 and the rear upper feeding roller 4 are both rotatably installed on the opening and closing housing 7. It should be noted that by starting the hydraulic cylinder, the opening and closing housing 7 can be moved, and the opening and closing housing 7 drives the front upper feeding roller 3 and the rear upper feeding roller 4 to move, automatically adjusting the feeding height according to the cross-sectional size of the incoming material, ensuring the stability of the material during shredding and improving the shredding efficiency.

[0027] Specifically, the shredding body is installed between the metal chain plate conveyor 1 and the belt conveyor 2. It should be noted that the material is shredded.

[0028] Specifically, the circumference of the lower feeding roller 5 is serrated. It should be noted that this increases the contact area with the material and prevents slipping and idling.

[0029] The metal chain plate conveyor 1 is used for feeding, and the material is sent to the shredding machine knife roller 6 through the front upper feeding roller 3, the rear upper feeding roller 4 and the lower feeding roller 5. After shredding, the material falls onto the upper part of the belt conveyor 2 through a sieve, and the belt conveyor 2 sends the material to a specified height.
