Description

Technical Field

[0001] This utility model relates to the field of belt conveyor hopper cleaning, and in particular to an automatic coal cleaning device for the head hopper of a belt conveyor. Background Technology

[0002] As a crucial piece of equipment for transferring bulk cargo materials at ports, belt conveyors operate for extended periods and have high material transfer efficiency. Their operational status is directly related to the efficiency of bulk cargo transfer. Due to the long operating hours and the variety of materials transported, belt conveyors are prone to accumulating large amounts of coal at the impact surface of the conveyor head hopper. On one hand, the coal accumulation at the impact surface of the head hopper alters the material's trajectory, causing the downstream belt to deviate, resulting in belt edge wear or even belt tearing. In severe cases, it can cause blockage of the conveyor head hopper, leading to equipment damage and impacting the entire production system, resulting in significant economic losses for the owner. On the other hand, cleaning the coal accumulation often requires manual cleaning after the machine has stopped, which is difficult and time-consuming, severely impacting production efficiency. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing an automatic coal cleaning device for the head hopper of a belt conveyor.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an automatic coal cleaning device for the head hopper of a belt conveyor, comprising a motor, a motor mounting base, coal cleaning scrapers, and a local operation box. The motor mounting base is installed on the outer wall of the side of the hopper to be cleaned, the motor is installed on the top of the motor mounting base and driven by the local operation box, the drive shaft of the motor passes into the hopper and is rotatably connected to the side of the hopper to be cleaned, and a pair of coal cleaning scrapers are symmetrically and detachably installed on the drive shaft and in contact with the inner wall of the side of the hopper to be cleaned, so as to realize the cleaning of accumulated coal.

[0005] Specifically, a pair of coal cleaning scrapers are fixedly connected to a spline sleeve at one end of the drive shaft. The drive shaft is provided with spline teeth that match the spline sleeve. The spline sleeve is fitted on the drive shaft and matches the spline teeth. A locking sleeve is threadedly connected to the end of the drive shaft away from the drive motor.

[0006] Specifically, a limiting ring is installed on the inner wall of the drive shaft near the side of the hopper where coal is to be cleared, and the spline sleeve is pressed onto the limiting ring by a locking sleeve.

[0007] In particular, the coal cleaning scraper has a detachable polyurethane scraper blade installed on the inner wall of the side wall near the coal to be cleaned.

[0008] Specifically, the polyurethane scraper blade is provided with a connecting protrusion, and the coal cleaning scraper blade is provided with a connecting groove corresponding to the connecting protrusion. The connecting protrusion is inserted into the connecting groove and fixed by bolts.

[0009] In particular, the coal cleaning scraper is equipped with several reinforcing ribs on both sides.

[0010] The beneficial effects of this utility model are: by setting up a motor, a coal cleaning scraper, and a local operation box, this utility model can effectively clean up accumulated coal through simple operation, and can clean up residual coal at any time, greatly improving coal cleaning efficiency, avoiding environmental pollution, and is simple to operate and can effectively ensure personnel safety.

[0016] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-4 As shown, an automatic coal cleaning device for a belt conveyor head hopper includes a motor 1, a motor mounting base 2, coal cleaning scrapers 3, and a local control box. The motor mounting base 2 is installed on the outer wall of the hopper 4 on the side to be cleaned. The motor 1 is mounted on top of the motor mounting base 2 and driven by the local control box. The drive shaft 5 of the motor 1 passes into the hopper 4 and is rotatably connected to the side to be cleaned. A pair of symmetrically detachable coal cleaning scrapers 3 are installed on the drive shaft 5 and contact the inner wall of the hopper 4 on the side to be cleaned to achieve coal cleaning. The device is controlled by a local control box, facilitating on-site debugging and maintenance. Different sizes of belt conveyor hoppers 4 can be adapted by selecting different sizes of motor 1 and coal cleaning scrapers 3.

[0019] A pair of coal cleaning scrapers 3 are fixedly connected to one end of the drive shaft 5 with a spline sleeve 6. The drive shaft 5 is provided with spline teeth that match the spline sleeve 6. The spline sleeve 6 is fitted on the drive shaft 5 and matches the spline teeth. The end of the drive shaft 5 away from the drive motor 1 is threadedly connected with a locking sleeve 7. A limiting ring 8 is clamped on the inner wall of the side of the drive shaft 5 near the coal to be cleaned in the funnel 4. The spline sleeve 6 is pressed onto the limiting ring 8 by the locking sleeve 7.

[0020] The spline sleeve 6 and spline teeth work together to ensure efficient torque transmission and prevent slippage. The locking sleeve 7 and the limiting ring 8 work together to prevent axial movement of the spline sleeve 6. Compared with traditional keyway connections, spline transmission has a stronger load-bearing capacity, better centering, and reduces the risk of uneven wear. The fixing method of the spline sleeve 6 and locking sleeve 7 does not require complicated tools. When disassembling, simply loosen the locking sleeve 7 to replace the coal cleaning scraper 3.

[0021] A polyurethane scraper blade 9 is detachably installed on the inner wall of the side wall of the coal cleaning scraper 3 near the coal to be cleaned. A connecting protrusion 10 is provided on the polyurethane scraper blade 9. A connecting groove corresponding to the connecting protrusion 10 is provided on the coal cleaning scraper 3. The connecting protrusion 10 is inserted into the connecting groove and fixed by bolts. Several reinforcing ribs 11 are provided on both sides of the coal cleaning scraper 3.

[0022] The polyurethane scraper blade 9 features high elasticity and wear resistance, effectively scraping away accumulated coal while minimizing damage to the inner wall of the funnel 4. Its detachable design allows for replacement after wear, reducing maintenance costs. The reinforcing ribs 11 enhance the rigidity of the coal cleaning scraper 3, preventing deformation and ensuring long-term stable contact with the funnel 4 wall.

[0023] In operation, this invention powers the motor 1 via a button on the local control box. The motor 1 drives the coal-cleaning scraper 3 to rotate at the impact surface of the head funnel, scraping away the accumulated coal and thus cleaning the coal. This invention effectively cleans accumulated coal through simple operation, allowing for the removal of residual coal at any time, greatly improving cleaning efficiency, avoiding environmental pollution, and ensuring personnel safety through its simple operation.
