Description

Technical Field

[0001] This utility model relates to the field of coal gangue processing technology, specifically to a coal gangue crushing device. Background Technology

[0002] Coal gangue is a solid waste discharged during the coal mining and washing processes. It is a blackish-gray rock with a low carbon content and harder than coal that is associated with coal seams during the coal formation process. It includes gangue from tunneling, gangue extracted from the roof, floor and interlayers during mining, and gangue from coal washing.

[0003] In the process of recycling coal gangue, crushing devices are used to pulverize it. Currently, bulldozers are used to load the coal gangue piled on the ground into the crushing device, where the crushing rollers can pulverize the coal gangue. However, when blocky coal gangue is directly fed into the crushing device, the high-speed rotation of the crushing rollers can damage the blades on the rollers, thus affecting the service life of the crushing device. To address this issue, we propose a coal gangue crushing device. Utility Model Content

[0004] The purpose of this invention is to provide a coal gangue crushing device to solve the problems mentioned in the background art.

[0006] As a further preferred embodiment of this technical solution, the outer side of the buffer plate is attached to the inner wall of the limiting hole, and the buffer plate is inclinedly arranged inside the crushing box.

[0007] As a further preferred embodiment of this technical solution, the outer side of the shaft is attached to the inner wall of the waist-shaped hole, and the outer side of the side plate is attached to the outer side of the crushing box.

[0008] As a further preferred embodiment of this technical solution, the outer edge of the base plate is inclined, and the surfaces of the pad and the buffer plate are on the same horizontal plane.

[0009] As a further preferred embodiment of this technical solution, the bolt and the threaded hole are connected by a fine-tooth thread engagement, and the bolt is tightly attached to the outer side of the base plate.

[0010] As a further preferred embodiment of this technical solution, a partition plate is provided below the buffer plate, and a long rod is fixedly installed on the outer side of the partition plate. One end of the long rod passes through the crushing box and is connected to a square plate. The square plate is attached to the outer side of the crushing box, and a spring is sleeved on the outer side of the long rod. The two ends of the spring abut against the outer side of the partition plate and the inner wall of the crushing box, respectively.

[0011] As a further preferred embodiment of this technical solution, the long rods are fixedly arranged in three groups on the outside of the partition plate, and the long rods and the crushing box are slidably connected.

[0012] This utility model provides a coal gangue crushing device, which has the following beneficial effects: This invention utilizes a V-shaped buffer plate arrangement inside the crushing chamber. After a bulldozer dumps coal gangue into the crushing chamber, the gangue accumulates on the surface of the protective pads, with the gangue positioned at the center of the crushing chamber. Subsequently, driven by a servo motor, the side plate moves along the shaft driven by a screw, allowing the buffer plate to slide within the limiting hole. This enables the gangue to fall directly to the center of the crushing roller with less force, effectively reducing the impact force of the gangue on the blades of the crushing roller and thus improving the protection of the crushing roller.

[0013] This invention features a partition plate positioned below a buffer plate. As the buffer plates separate, the coal gangue falls directly into the crushing rollers and is crushed. During the crushing process, if the coal gangue breaks or large pieces fly off, the partition plate acts as a buffer. Furthermore, the long rod and spring work together to cushion the partition plate, effectively preventing the coal gangue from getting stuck between the crushing rollers and the crushing box.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides a technical solution as follows: Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, a coal gangue crushing device includes a crushing device, which includes a crushing box 1. Two limiting holes 2 are opened on the outer side of the crushing box 1. A buffer plate 3 is inserted into each of the two limiting holes 2. Two shafts 4 are fixedly installed on the outer side of the buffer plate 3. The other ends of the two shafts 4 pass through a waist-shaped hole and are fixedly connected to a side plate 5. The waist-shaped hole is opened on the outer side of the crushing box 1. A screw 6 is engaged with the side plate 5. One end of the screw 6 is rotatably connected to a fixed plate 7. The fixed plate 7 is fixedly disposed on the outer side of the crushing box 1. The other end of the screw 6... One end is fixedly connected to the shaft end of the servo motor 8, which is fixedly installed on the outside of the crushing box 1. The surface of the buffer plate 3 has a groove 9, and a base plate 10 is inserted into the groove 9. A protective gasket 11 is fixedly installed on the base plate 10. Bolts 12 are inserted into the base plate 10 and the protective gasket 11, and the bolts 12 engage with the threaded hole 13. The threaded hole 13 is opened on the buffer plate 3. The buffer plate 3 is V-shaped and installed inside the crushing box 1. After the bulldozer puts coal gangue into the crushing box 1, the coal gangue accumulates on the surface of the protective gasket 11, and the coal gangue is... At the center of the crushing chamber 1, driven by the servo motor 8, the side plate 5 moves along the screw 6 and shaft 4. This allows the buffer plate 3 to slide within the limiting hole 2, enabling the coal gangue to fall directly to the center of the crushing roller with less force. This effectively reduces the impact force of the coal gangue on the blades of the crushing roller, thus improving the protection of the crushing roller. The outer side of the buffer plate 3 is attached to the inner wall of the limiting hole 2. The buffer plate 3 is inclined inside the crushing chamber 1, effectively bearing and buffering the coal gangue. The outer side of the shaft 4 is attached to the waist-shaped hole. On the inner wall, the side plate 5 is attached to the outer side of the crushing box 1, so that the buffer plate 3 can slide stably inside the crushing box 1. The outer edge of the bottom plate 10 is set to be inclined. The surface of the protective pad 11 and the buffer plate 3 is on the same horizontal plane, so that when the protective pad 11 is replaced, the bottom plate 10 can be quickly inserted into the inside of the groove 9. The bolt 12 and the threaded hole 13 are connected by fine thread engagement. The bolt 12 is close to the outer side of the bottom plate 10. By using fine thread, it can have self-locking performance, thereby improving the stability of the connection.

[0018] like Figure 2 and Figure 4As shown, a partition plate 14 is provided below the buffer plate 3. A long rod 15 is fixedly installed on the outer side of the partition plate 14. One end of the long rod 15 passes through the crushing box 1 and is connected to a square plate 16. The square plate 16 is attached to the outer side of the crushing box 1. A spring 17 is sleeved on the outer side of the long rod 15. The two ends of the spring 17 respectively abut against the outer side of the partition plate 14 and the inner wall of the crushing box 1. The long rod 15 is fixedly arranged in three groups on the outer side of the partition plate 14. The 5 and the crushing box 1 are slidably connected. The partition plate 14 is located below the buffer plate 3. As the buffer plates 3 separate, the coal gangue can fall directly into the middle of the crushing roller to be crushed. During the process, when the coal gangue is broken or large pieces of coal gangue are flying, the partition plate 14 can play a role in resisting. The long rod 15 and the spring 17 are provided to buffer the partition plate 14, effectively preventing the coal gangue from getting stuck between the crushing roller and the crushing box 1.

[0019] This utility model provides a coal gangue crushing device, the specific working principle of which is as follows: During operation, as the coal gangue is poured into the crushing box 1, it falls directly onto the buffer plate 3 and accumulates on the surface of the protective pad 11, placing the coal gangue at the center of the crushing box 1 and shortening the distance between the coal gangue and the crushing roller. Then, driven by the servo motor 8, the side plate 5 moves along the screw 6 and shaft 4, allowing the buffer plate 3 to slide within the limiting hole 2. This allows the coal gangue to fall directly into the center of the crushing roller with less force. At this location, to effectively reduce the impact force of coal gangue on the crushing roller, a partition plate 14 is set below the buffer plate 3. As the buffer plates 3 separate, the coal gangue can fall directly into the middle of the crushing roller to be crushed. During the process, when the coal gangue breaks or large pieces of coal gangue are flying, the partition plate 14 can play a role in resisting. In addition, the long rod 15 and the spring 17 work together to buffer the partition plate 14, effectively preventing coal gangue from getting stuck between the crushing roller and the crushing box 1.
