[0003] For example, "An adjustable single-roll crusher" with Chinese patent publication number CN216826451U, the utility model discloses an adjustable single-roll crusher, which belongs to the technical field of single-roll crushers. The key points of its technical solution include a cylinder, the output ends of the two cylinders respectively penetrate the left and right sides of the box body and extend to the interior of the box body and are fixedly connected with a moving block, the other ends of the two moving blocks are fixedly connected with a moving rod, and an articulated seat is installed below the opposite ends of the two crushing plates, and the two moving rods are movably connected to the articulated seat through a movable shaft, and the cylinder pushes the moving block to move in the direction close to the crushing roller, and at the same time, the moving block is forced to push the moving rod to move, so that the moving rod pushes the crushing plate to swing in the direction close to the crushing roller until the distance between the crushing plate and the crushing roller reaches the required effect, and the cylinder can stop pushing, thereby realizing that the distance between the crushing plate and the crushing roller can be flexibly adjusted according to the particle size of the crushed material to be crushed, thereby improving the practicality of the device.

[0004] However, in actual use, when adjusting the distance between the two crushing plates and the crushing roller, two cylinders are needed to drive the two crushing plates. If the two cylinders cannot push synchronously, the distance between the two crushing plates and the crushing roller will not be consistent, which will affect the accuracy of the particle size of the material after crushing. It is not convenient to ensure the consistency of the distance between the two crushing plates and the crushing roller by moving the two crushing plates synchronously. Utility Model Content
