Description

Technical Field

[0001] This utility model relates to the field of cleaning and anti-clogging technology for coal chutes, specifically an automatic cleaning and anti-clogging device for coal chutes. Background Technology

[0002] The automatic coal chute cleaning and anti-clogging device is a piece of equipment used in coal chute systems. It is mainly used to solve the problem of coal clogging in coal chute systems, to clear coal accumulation and blockages in the pipe, and to ensure that coal can be transported smoothly in the coal chute system, thereby improving the working efficiency of the coal conveying system.

[0003] The prior art discloses an automatic cleaning and anti-clogging device for coal chutes, application number 202011157152.4, comprising a fixed base, a main cover, a rotating disk, a fixed pipe, and a drive motor. The main cover is fixed to the top of the fixed base. The fixed pipe is located at the top of the inner cavity of the main cover, and the rotating disk is located at the bottom of the inner cavity of the main cover. A gear groove is located at the center of the side of the rotating disk. Ball bearings are located on the inner side of the main cover and are rotatably connected to the upper and lower sides of the gear groove of the rotating disk. The fixed pipe is circular, and a scraper is fixed to its inner wall near the bottom. The bottom end of the scraper extends into the interior of the rotating disk. The drive motor is fixed to the fixed base, and a gear disk is mounted on the output shaft of the drive motor, meshing with the gear groove. A material detection module, including a sensor and a signal transceiver, is located on the inner wall of the fixed pipe. A drive motor controller, connected to the drive motor via wires, is located inside the fixed base. This invention automatically scrapes away blocked coal chutes, achieving good cleaning results and being energy-efficient.

[0004] The aforementioned device works by using a movable scraper to remove blockages in the coal feed. However, during use, the scraper moves internally and mechanically compresses the feed pipe when it becomes blocked, causing it to deform under pressure. This results in poor performance and requires improvement. Utility Model Content

The sliding shell 201 is slidably connected to the inside of the groove 104. The first telescopic rod 202 is movably connected to the top of the sliding shell 201, with one end connected to the inside of the groove 104, allowing the sliding shell 201 to be in a movable state to prevent blockage. Simultaneously, vibration can dislodge any blocked material. The spring sleeve 203 is located on the surface of the first telescopic rod 202. The discharge port 204 is located at the bottom of the sliding shell 201. The inner groove 205 is located inside the sliding shell 201 and serves as the primary discharge mechanism. A flow rate sensor is installed inside the inner groove 205, electrically connected to the control component 211 for detection. It identifies the internal flow rate to determine if blockage has occurred. The anti-blockage unit consists of the control component 211, a first vibration motor 212, a second vibration motor 213, a cylinder 214, and a... The system consists of two telescopic rods 215 and a connecting plate 216. A control component 211 is located on the side of the sliding shell 201.
