Description

Technical Field

[0001] This utility model relates to the technical field of coal mine conveying equipment, specifically to an infrared-triggered self-cleaning anti-deviation device for chutes. Background Technology

[0002] In the material transfer stage of a coal mine washing and processing system, the belt conveyor, as the core conveying equipment, is crucial to the entire production process due to its stable operation. However, in actual production, as the coal flows down the chute wall, it is highly susceptible to uneven material loading due to various factors, including material characteristics (such as uneven particle size distribution and moisture variations), chute structural design defects (such as unreasonable angles and high inner wall roughness), and unreasonable guide chute structure. Uneven material loading leads to uneven belt tension, which in turn causes belt misalignment. This problem has many serious consequences:

[0003] High equipment maintenance costs: Frequent belt misalignment will aggravate the wear of belts and components such as idlers and rollers, leading to frequent failures such as belt tearing and idler damage. Regular maintenance and replacement of parts are required, which greatly increases the equipment maintenance costs.

[0004] High cost of manual adjustment: To ensure the normal operation of the belt, a large number of people need to be arranged to frequently adjust the belt position, which not only consumes a lot of time and energy, but also increases labor costs.

[0005] Significant safety hazards: Belt misalignment may cause material spillage, resulting in waste of coal resources. At the same time, spilled material accumulating around the equipment may cause equipment failure, and even pose a potential risk of fire and other safety accidents, seriously threatening the lives of personnel on the production site and the stable operation of the equipment.

[0006] Therefore, developing a device that can effectively clean the material adhering to the inner wall of the chute and prevent belt misalignment has become a key issue that the coal washing and beneficiation industry urgently needs to address. Utility Model Content

[0007] The purpose of this invention is to provide an infrared-triggered self-cleaning anti-deviation device for chutes. By accurately monitoring the material accumulation, it automatically and efficiently cleans the material adhering to the inner wall of the chute, fundamentally solving the problem of belt deviation, significantly reducing equipment maintenance and manual adjustment costs, and comprehensively improving the safety and economic benefits of coal mine washing and beneficiation production.

[0008] This utility model includes a scraper installed on the inner side of the chute wall. The scraper head is installed close to the side of the chute wall. The scraper is connected to the hydraulic rod of a hydraulic device. The hydraulic rod extends and retracts under hydraulic pressure, thereby driving the scraper to move up and down along the inner side of the chute wall to remove residual material on the chute wall.

[0009] Preferably, a scraper is installed at the blade head of the scraper, and the scraper is set close to the side wall of the chute.

[0010] Preferably, the cross-section of the scraper has an inverted triangular structure that is thicker at the top and narrower at the bottom.

[0011] Preferably, a cleaning strip is also fixed to the inner side of the chute wall, the cleaning strip extends along the width direction of the chute wall, and a gap is provided between the cleaning strip and the chute wall for the scraper to pass through.

[0012] Preferably, the inner side of the chute wall is also provided with a limiting plate, and the two limiting plates are distributed on the left and right sides of the scraper.

[0013] Preferably, the chute wall is provided with a vertical stroke groove, which is located at the connection between the scraper and the hydraulic rod.

[0014] Preferably, a laser beam switch is also provided on the inner side of the chute wall. The laser beam switch includes a transmitter and a receiver, and the transmitter and receiver are on the same horizontal plane.

[0015] Preferably, the scraper is made of polyurethane material.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] The orientations mentioned in this specification are based on the orientation of the infrared-triggered chute self-cleaning anti-deviation device of this utility model when it is working normally. They do not limit the orientation during storage and transportation, but only represent relative positional relationships, not absolute positional relationships.

[0026] like Figures 1 to 2 As shown, an infrared-triggered self-cleaning anti-deviation device for a chute includes a scraper 2 installed on the inner side of the chute wall 1. The scraper 2 has its blade head installed close to the side of the chute wall 1. The scraper 2 is connected to a hydraulic rod 4 of a hydraulic device 3. The hydraulic rod is made of high-strength alloy material, possessing high strength, high toughness, and good wear resistance. Through advanced hydraulic drive technology, it can provide stable and adjustable push-pull force. Under the action of hydraulic pressure, the hydraulic rod 4 extends and retracts up and down, thereby driving the scraper 2 to move up and down along the inner side of the chute wall 1, thus scraping off the residual material on the chute wall 1.

[0027] Furthermore, a scraper 5 is installed at the blade head of the scraper 2. The cross-section of the scraper 5 is an inverted triangular structure with a thicker upper end and a narrower lower end. The scraper 5 is set close to the side wall of the chute. The scraper 5 is made of polyurethane material, which has good flexibility and wear resistance. It can closely fit the complex uneven structure of the inner wall of the chute. Driven by the hydraulic rod 4, it can efficiently clean the material hanging on the inner wall of the chute.

[0028] Furthermore, a cleaning strip 6 is fixedly provided on the inner side of the chute wall 1. The cleaning strip 6 is made of polyurethane material and extends along the width direction of the chute wall 1. A gap is provided between the cleaning strip 6 and the chute wall 1 for the scraper 2 to pass through. When the scraper 2 moves up and down under the push of the hydraulic rod 4, the scraper 5 passes through the gap between the cleaning strip 6 and the chute wall 1, and the material attached to the scraper 5 is scraped off by the cleaning strip 6 to ensure the cleanliness of the scraper 5.

[0029] Furthermore, a limiting plate 7 is provided on the inner side of the chute wall 1. Two limiting plates 7 are distributed on the left and right sides of the scraper 2. The limiting plates 7 are used to limit the maximum stroke of the scraper 2 to prevent it from deviating from the predetermined track, making it safer to use.

[0030] Furthermore, the chute wall 1 is provided with a vertical stroke groove 8, which is located at the connection between the scraper 2 and the hydraulic rod 4. The surface of the stroke groove 8 is processed with high precision, and has extremely high flatness and smoothness, which provides stable and precise motion guidance for the hydraulic rod 4, ensuring that the hydraulic push rod moves without jamming or shaking, and ensuring that the scraper 2 can clean the material stably and efficiently along the predetermined trajectory.

[0031] Furthermore, a laser beam switch 9 is also provided on the inner side of the chute wall 1. The laser beam switch 9 includes a transmitter and a receiver, which are on the same horizontal plane. The laser beam switch 9 is installed at key monitoring positions on both sides of the chute wall 1 of the impact point liner 10. It adopts high-precision optical sensors and advanced signal processing technology, which can detect the material accumulation in real time and accurately. When the material accumulation blocks the infrared light path to a preset threshold, the signal is quickly transmitted to the control system, and the hydraulic rod 4 is automatically activated to clean the material, effectively avoiding the problem of belt misalignment caused by material accumulation.

[0032] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
