A coal briquette machine

Abstract

The utility model discloses a coal briquette machine, including a feeding assembly, wherein the feeding assembly includes a feeding box, a driving motor, a feeding pipe, a conveyor belt, an active roller, a driven roller, a buffer plate, a limit plate, a damping rod, a tension spring and two mounting seats; the two ends of the active roller and the two ends of the driven roller are symmetrically rotatably connected to the inner front wall and the inner rear wall of the feeding box. The utility model can receive and convey coal balls through the conveyor belt. When the coal balls fall from the surface of the conveyor belt to the surface of the buffer plate, the tension spring and the damping rod can cooperate to play a buffering role, and then under the guidance of the buffer plate, the coal balls roll into the feeding pipe. Since the feeding pipe is arc-shaped, the coal balls can roll in the feeding pipe. The coal balls are received by the conveyor belt, which reduces the impact on the coal balls. The coal balls are guided and discharged through the feeding pipe, so that the coal balls can roll to the external conveying equipment, thereby reducing the damage to the coal balls.

It has the characteristics of simple structure, convenient operation and high efficiency, and is widely used in the coal industry. The main function of coal briquette machine is to reprocess coal powder into spherical particles and increase the density of coal for easy storage and transportation. In addition, coal briquette machine can also be used to press other granular materials.

[0003] After the existing coal briquette machine makes coal briquettes, the coal briquettes fall through the lower hopper of the briquette machine to the external conveying equipment. When falling, under the action of gravity, the coal briquettes will be subjected to a large impact force, thereby causing damage to the coal briquettes. In order to solve this problem, the design and operation of the coal briquette machine are often improved in the prior art, including the following solutions:

[0004] 1. Reduce the falling height: Try to shorten the height difference between the coal balls from the outlet of the briquette press and the conveyor belt to reduce the impact of the coal balls during the falling process.

[0005] 2. Add buffer devices: When the coal balls fall onto the conveyor belt, some buffer devices, such as cushions or shock absorbers, can be added to absorb the impact force when the coal balls fall.

[0006] 3. Control the quality of briquettes: Improve the pressing quality of briquettes to make them stronger and more durable and able to withstand greater impact.

[0007] 4. Optimize the conveyor belt material: Select a conveyor belt material with shock absorption, wear resistance and other properties to reduce damage to coal balls during transportation.
