Description

Technical Field

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

[0002] In the coal mining and processing industry, coal gangue, as a major solid waste, needs to be crushed for resource utilization. Existing coal gangue crushing and feeding devices mostly adopt fixed feeding structures or simple conveyor belt designs. During the feeding process, coal gangue is prone to sliding or accumulating, resulting in intermittent feeding, low efficiency, and the connection between the feeding device and the crushing cylinder is not open, meaning the feeding device is directly facing the crushing cylinder's inlet. This leads to significant dust dispersion during crushing, worsening the working environment and posing safety hazards. Therefore, this application proposes a coal gangue crushing and feeding device to solve the above problems. Utility Model Content

[0012] (III) Beneficial Effects

[0013] The beneficial effects of this utility model are as follows:

[0014] This type of coal gangue crushing and feeding device, with its support rollers in the feeding box working in conjunction with the conveyor belt and pusher bar, can forcibly push the coal gangue upwards towards the crushing cylinder, effectively preventing material slippage or accumulation and ensuring continuous and stable feeding operations. The feeding box seals the conveyor belt, and a sealing shell is installed at the connection between the feeding box and the crushing cylinder to prevent dust from escaping during coal gangue conveying and crushing.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1-4As shown, this utility model provides a technical solution: a coal gangue crushing and feeding device, including a crushing cylinder 1, a crushing shaft 9 installed inside the crushing cylinder 1, and the crushing shaft 9 driven by a motor 11 at the bottom end. A discharge chute 10 is formed on the bottom outer wall of the crushing cylinder 1, and a liftable sealing plate is fitted on the bottom outer wall of the crushing cylinder 1 to seal the discharge chute 10. The bottom side of the crushing cylinder 1 is conical. After the coal gangue enters the crushing cylinder 1 through the sleeve 2, the motor 11 drives the crushing shaft 9 to rotate at high speed to crush the material. Guided by the conical structure at the bottom of the crushing cylinder 1, the material is discharged through a circular discharge chute 10. The opening and closing degree of the discharge chute 10 is adjusted by a lifting sealing plate to control the discharge speed and flow rate. Simultaneously, the lifting sealing plate can also seal the discharge chute 10 during the crushing process to prevent dust escape. During feeding and crushing, the sealing shell and bolt locking structure maintain the airtightness between the feeding box 3 and the crushing cylinder 1 to prevent dust escape. A sleeve 2 is connected to the top side of the crushing cylinder 1, and the sleeve 2 is connected to one end of the top side of the feeding box 3. The top of the feeding box 3 is connected to the sleeve 2. A sealing shell is provided at the connection position of the cylinder 2. The top connection between the sleeve 2 and the crushing cylinder 1 is locked with bolts. The feeding box 3 is inclinedly set on one side of the crushing cylinder 1. Multiple support rollers 4 are installed inside the feeding box 3, and the top support rollers 4 are driven by motor 5. The support rollers 4 are connected to the conveyor belt 6. The multiple support rollers 4 in the middle support the conveyor belt 6 to ensure the stable conveying of coal gangue by the conveyor belt 6. Several push bars 7 are installed on the outside of the conveyor belt 6. The height of the push bars 7 is not less than 2cm. The setting of the push bars 7 can... To effectively prevent material slippage or accumulation and ensure continuous and stable feeding operations, a feeding port is provided at the bottom upper side of the feeding box 3. A storage box 8 is installed at the feeding port at the bottom upper side of the feeding box 3. When coal gangue is put into the storage box 8, the motor 5 is started, which drives the top support roller 4 to drive the conveyor belt 6 to rotate. The push bar 7 on the conveyor belt 6 forcibly pushes the coal gangue upward along the inclined feeding box 3 and evenly conveys it to the inlet of the sleeve 2. The conveying speed of the conveyor belt 6 can be controlled by adjusting the speed of the motor 5, so as to achieve precise adjustment of the feeding amount.

[0022] The operational steps for this application are as follows:

[0023] Coal gangue is put into storage box 8, motor 5 is started, and the top side support roller 4 drives the conveyor belt 6 to rotate. The push bar 7 on the conveyor belt 6 forcibly pushes the coal gangue upward along the inclined feeding box 3 and evenly conveys it to the inlet of sleeve 2. The conveying speed of the conveyor belt 6 can be controlled by adjusting the speed of motor 5, so as to achieve precise adjustment of the feeding amount.

[0024] After the coal gangue enters the crushing cylinder 1 through the sleeve 2, the motor 21 drives the crushing shaft 9 to rotate at high speed to crush the material. The crushed material is guided by the conical structure at the bottom of the crushing cylinder 1 and discharged through a discharge chute 10. The opening and closing degree of the discharge chute 10 can be adjusted by the lifting sealing plate to control the discharge speed and flow rate. At the same time, the discharge chute 10 can also be sealed by the lifting sealing plate during the crushing process to prevent dust from escaping. During the feeding and crushing process, the sealing shell and bolt locking structure are used to maintain the airtightness of the feeding box 3 and the crushing cylinder 1 to prevent dust from escaping.
