Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a single-roller large block crusher for the compound fertilizer industry. Background Technology

[0002] The crushing section of a single-roll crusher typically consists of a toothed roller and a fixed grate plate housed within the crushing chamber. The roller's shaft is driven by a geared motor. During operation, large pieces of material enter the crushing chamber through the feed inlet. The high-speed rotating crushing teeth impact and split the material, while the roller teeth and the fixed grate plate exert pressure, crushing the material to the required particle size and discharging it through the grate plate gaps. In compound fertilizer production, it is used for coarse or medium crushing of lumpy compound fertilizer raw materials, providing materials of suitable particle size for subsequent granulation and mixing processes.

[0003] The crushing teeth on the existing single-roll crusher are relatively short and fixed. After a period of use, the crushing teeth are prone to wear. To prevent the crushing effect from being affected, they need to be disassembled and replaced. However, the disassembly and replacement process is time-consuming and labor-intensive, which prolongs the downtime of the crusher, thereby affecting work efficiency and increasing production costs. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a single-roller large-piece crusher for the compound fertilizer industry, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a single-roller large-piece crusher for the compound fertilizer industry, comprising:

[0006] A crushing assembly, comprising a crushing hopper, a receiving plate, a shaft, a receiving disc, and a metal rod, wherein the receiving plate is fixedly connected to both sides of the inner wall of the crushing hopper, the shaft is movably connected in the crushing hopper, the receiving disc is fixedly connected to the outer side of the shaft, and the metal rod is fixedly connected to the outer side of the receiving disc;

[0007] A compensation and adjustment assembly includes a rectangular groove and a crushing rod. The rectangular groove is formed on the metal rod, and the crushing rod is movably connected in the rectangular groove.

[0008] Furthermore, the compensation adjustment assembly also includes a rectangular block, a circular groove, a hydraulic cylinder, and a hydraulic actuator. The rectangular block is movably connected to the side of the crushing rod, and the rectangular block is movably connected to the rectangular groove. One end of the hydraulic cylinder is fixedly connected to the side of the rectangular block. A circular groove is formed through the metal rod, and the hydraulic cylinder is inserted into the circular groove. The hydraulic actuator is fixedly connected to the side of the metal rod, and the other end of the hydraulic cylinder is fixedly connected to the middle of the hydraulic actuator.

[0009] Furthermore, the circular groove is connected to the rectangular groove.

[0010] Furthermore, the compensation adjustment component also includes a guide groove and a guide block. The rectangular groove has guide grooves at both the upper and lower ends, the rectangular block is fixedly connected to the guide block at both the upper and lower ends, and the guide block is movably connected to the guide groove.

[0011] Furthermore, it also includes an auxiliary breaking component, which includes a conical block. The front end of the breaking rod is fixedly connected to the conical block, and the conical block is located on one side of the rectangular block.

[0012] Furthermore, the auxiliary breaking component also includes a receiving groove, a rotating rod, and a motor. The receiving groove is formed through the rectangular block. The rotating rod is fixedly connected to the side of the breaking rod. The rotating rod is movably connected in the receiving groove. The output end of the motor is connected to the side of the rotating rod.

[0013] Furthermore, the auxiliary damage component also includes an L-shaped rod, with the rectangular block fixedly connected to one end of the L-shaped rod and the other end of the L-shaped rod fixedly connected to a motor.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, when the crushing rod wears out, the hydraulic actuator is opened, which drives the hydraulic cylinder to extend, thereby pushing the rectangular block and the crushing rod to move. This allows the moved-out crushing rod portion to compensate for the worn crushing rod portion, thus ensuring the crushing effect. The above process can be achieved without disassembling or replacing the crushing rod, thereby avoiding the downtime of the crusher due to crushing rod wear, thus ensuring overall production efficiency and indirectly saving production costs.

[0016] Based on the above-mentioned beneficial effects, by turning on the motor, the crushing rod can drive the cone block to rotate. When in contact with the material, the rotation generates tangential force, forming a "impact + shearing + grinding" compound effect. Moreover, the rotating cone block can form multiple cracks on the material surface through multi-angle impact, reducing the critical stress required for crushing. This makes it suitable for crushing materials with high hardness, while also accelerating the crushing rate. Attached Figure Description
