The crushing roller 3 crushes the coal blocks. During the crushing process, the coal blocks will be collected by the conveyor belt 8 set on the side wall of the machine body 1, and then the conveyor belt 8 will be driven to rise by the belt shaft 23, which will drive the coal blocks to move to the top of the machine body 1. After reaching the top, the cleaning brush 25 will contact the coal blocks on the conveyor belt 8. At this time, the cleaning shaft 24 drives the cleaning brush 25 to reciprocate, and the cleaning brush 25 will be used to sweep the coal blocks on the conveyor belt 8, so that the coal blocks will be swept onto the crushing roller 3 again. That is, the crushing roller 3 is used for multiple crushing, and finally the coal blocks will fall onto the unloading plate 5 below the crushing roller 3, and the crushed coal blocks will pass through the unloading plate 5 The coal blocks fall to the bottom of the machine body 1 through the opening on the upper surface. During the falling process, the rotating shaft 6 drives the crushing blade 7 to rotate rapidly, and the fallen coal blocks are broken again into small pieces. Then the coal blocks fall to the discharge port 9 at the bottom of the machine body 1, and then fall from the discharge port 9 to the conveyor belt 18 below. The conveyor belt 18 transports the coal blocks to the boiler for combustion. The crushing rollers 3 and the crushing blades 7 in the machine body 1 can quickly crush the coal blocks, so that they can be burned more fully in the boiler, and the coal blocks that have not been cleaned by the cleaning brush 25 will fall to the crushing blades 7 along with the transmission of the conveyor belt 8, and will be crushed again by the crushing blades 7.

During operation, the coal blocks will fall onto the guide plates 21 after being crushed by the crushing rollers 3, and the guide coal blocks passing through the guide plates 21 will contact the crushing blades 7 and thus be crushed. During the crushing, the coal blocks will fly in the machine body 1. At this time, the coal blocks can be pushed through the cylinder and pushed to the discharge port 9 for discharge, so as to avoid the coal blocks remaining inside the machine body 1. The end of the guide plate 21 is arranged parallel to the discharge port 9, so as to prevent the coal blocks from falling directly into the discharge port 9 when they fall.

[0027] Further, such as Figure 1 As shown, a support column 13 is fixedly connected to the bottom of the machine body 1; one end of the support column 13 away from the machine body 1 is fixedly connected to the top of the conveying side plate 16.

When working, the discharge pipe 11 is fixedly connected to the bottom of the discharge port 9 to guide the coal blocks to prevent the coal blocks from splashing during the falling process. The discharge valve 12 can control the opening and closing of the discharge pipe 11. When the crushing blade 7 is working, the discharge valve 12 closes the discharge pipe 11 and the discharge port 9 is prohibited from discharging. After the crushing is completed, the discharge pipe 11 is opened and the coal blocks can be discharged from the discharge pipe 11.

At this time, the cleaning shaft 24 drives the cleaning brush 25 to reciprocate, and the cleaning brush 25 will be used to sweep the coal on the conveyor belt 8, so that the coal is swept back onto the crushing roller 3, that is, the crushing roller 3 is used for multiple crushing, and finally the coal is The coal blocks will fall onto the discharge plate 5 below the crushing roller 3, and the crushed coal blocks will fall to the bottom of the machine body 1 through the opening on the discharge plate 5. During the falling process, the rotating shaft 6 drives the crushing blade 7 to rotate rapidly to break the fallen coal blocks again into small pieces. Then the coal blocks fall to the discharge port 9 at the bottom of the machine body 1, and then fall from the discharge port 9 to the conveyor belt 18 below. The conveyor belt 18 transports the coal blocks to the boiler for combustion. The crushing roller 3 and the crushing blade 7 in the machine body 1 can quickly crush the coal blocks, so that they can burn more fully in the boiler, and the coal blocks that have not been cleaned by the cleaning brush 25 will fall to the crushing blade 7 along with the transmission of the conveyor belt 8, and will be crushed again by the crushing blade 7.
