[0029] Example 1

[0030] Reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a crusher capable of allowing only coal particles that meet the desired requirements to pass through the crusher and enter the next process. The crusher comprises a plurality of evenly distributed engaging grooves 102a formed on both sides of the inner wall of a body 101. Transverse plates 102b are inserted into the engaging grooves 102a. The gaps between the transverse plates 102b correspond to the desired coal particle size. By increasing or decreasing the number or spacing of the transverse plates 102b, the space between the transverse plates 102b can be adjusted, thereby affecting the size of the coal particles.

[0031] Specifically, rectangular grooves 102c are provided at both ends of the horizontal plate 102b, and a reinforcing plate 103b is movably connected in the rectangular groove 102c. A concave groove 103a is provided at the bottom of the clamping groove 102a to match the lower end of the reinforcing plate 103b, and the reinforcing plate 103b is matched with the clamping groove 102a. When the reinforcing plate 103b is placed in the clamping groove 102a, the lower end of the reinforcing plate 103b is inserted into the rectangular groove 102c and the concave groove 103a in sequence. The surface of the reinforcing plate 103b is flush with the inner wall of the body 101, which improves the stability of the horizontal plate 102b. When the horizontal plate 102b is not needed in the clamping groove 102a, the reinforcing plate 103b can also be placed in the clamping groove 102a, which can prevent the slag from entering the clamping groove 102a when the raw coal is crushed, which increases the difficulty of cleaning the crusher in the later stage.

[0032] Furthermore, a circular hole 103c is provided on the surface where the horizontal plate 102b and the reinforcement plate 103b contact each other, and the circular fixing hole 103d is provided on the surface of the other side of the body 101. The fixing hole 103d passes through several clamping grooves 102a in sequence. The position of the fixing hole 103d is aligned with the position of the circular hole 103c after the horizontal plate 102b and the reinforcement plate 103b are inserted into the clamping groove 102a, and a fixing rod 103e is movably connected in the fixing hole 103d, which makes the fixing rod 103e pass through the fixing hole 103d and several circular holes 103c in sequence, and the horizontal plate 102b and the reinforcement plate 103b are firmly fixed in the body 101, ensuring that the structural connection between the horizontal plate 102b and the reinforcement plate 103b and the body 101 is firm and reliable.

[0035] Among them, the outside of the driving rod 202a is provided with several groups of plug-in slots 202b, and the disassembly slots are semicircular and evenly distributed on the outside of the driving rod 202a. The other end surface of the driving rod 202a is provided with a connecting hole 202c, which is connected to the several plug-in slots 202b in turn. A fixed block 203a and a crushing claw 203b are provided in the plug-in slot 202b. The crushing claw 203b is driven by the driving rod 202a to realize positive rotation and rotate in the gap between the horizontal plates 102b to squeeze and crush the raw coal that cannot pass through the gap between the horizontal plates 102b. In this way, the raw coal can adapt to the designed gap between the horizontal plates 102b, and then be crushed and squeezed. The fixed block 203a is used to adjust the use of the crushing claw 203b. The fixed block 203a and the crushing claw 203b can replace each other's positions, and the appropriate crushing claw 203b can be added or reduced according to the amount of the gap set between the horizontal plates 102b for crushing.

[0036] Furthermore, the surfaces of the fixing block 203a and the crushing claw 203b are both provided with a second circular hole 203c of the same diameter as and aligned with the connecting hole 202c, and the connecting rod 202d is movably connected in turn in the connecting hole 202c and the circular hole, so that the fixing block 203a and the crushing claw 203b can be firmly fixed in the driving rod 202a, ensuring that the structural connection between the fixing block 203a and the crushing claw 203b and the driving rod 202a is firm and reliable. The outer sides of the other ends of the two sets of fixing rods 103e are connected respectively by connecting The plate 104b is fixedly connected to the connecting rod 202d, and a fixing groove 104a adapted to the connecting plate 104b is opened on the other side surface of the body 101. When the fixing rod 103e and the connecting rod 202d are fully inserted into the fixing hole 103d and the connecting hole 202c respectively, the connecting plate 104b will be limited in the fixing groove 104a. By observing the position of the connecting plate 104b, it is shown that the fixing rod 103e and the connecting rod 202d have firmly fixed the horizontal plate 102b or the crushing claw 203b.
