Description

Technical Field

[0001] The utility model relates to the technical field of material discharge chutes, in particular to a material discharge chute anti-blocking device. Background Art

[0002] At present, the unloading chute of the automatic coal sampling machine has the problems of short pipe body and rapid diameter change. At a height of less than 500mm, the diameter of the collecting hopper is sharply reduced from a 500mm square mouth to a 150mm round mouth. Especially when the moisture content of the mined coal is high, the material is easily accumulated at the receiving port and causes blockage, affecting the smooth operation of the equipment.

[0003] To sum up: In order to prevent material blockage and improve the operating stability of the equipment, it is necessary to design a material chute anti-blocking device.

[0004] For example, a docking device suitable for a coal conveyor belt disclosed in the authorization announcement number CN208577095U includes a coal conveyor chute, a belt sealing plate, a rotary adjustment plate, an elliptical adjustment plate, and a chute fixing plate. The coal conveyor chute is installed on the chute fixing plate, the chute fixing plate is clamped in the mounting hole of the elliptical adjustment plate, the elliptical adjustment plate is slidably arranged on the rotary adjustment plate, an elliptical hole is opened on the rotary adjustment plate, so that the discharge port of the coal conveyor chute slides along the long axis direction of the elliptical hole, and the rotary adjustment plate is rotatably arranged on the belt sealing plate so that the discharge port of the coal conveyor chute can achieve 360° adjustment docking. The utility model realizes 360° arbitrary adjustment of the coal conveyor chute by adjusting the rotation of the rotary adjustment plate and the linear extension and contraction of the elliptical adjustment plate, adapting to a larger error range; the chute fixing plate can ensure that the coal conveyor chute can still complete docking when it is skewed at a certain angle, and the sealing effect is good; it makes coal conveying smoother, avoids leakage during coal conveying, and improves coal conveying efficiency. However, the utility model lacks anti-blocking and independent fixing measures, which is not convenient for ensuring the smoothness and convenience of the utility model during use. For this reason, we propose a material chute anti-blocking device, which solves the anti-blocking and independent fixing problems of the utility model, improves the practical effect of the device, and ensures the continuity of coal mine transportation operations.

[0015] 1. This device for preventing material from being blocked in a material discharge chute is equipped with a fixed pad, a reinforcing strap and an electric vibrator arranged on the main body. When the material discharge chute is in a material conveying operation, the vibration effect of the electric vibrator can be used to prevent the material from adhering to or blocking the material discharge chute, thereby improving the continuity of material transportation and ensuring operating efficiency.

[0016] 2. This device for preventing material blockage in a material discharge chute achieves independent fixing through fixed support plates and fixed blocks on both sides of the receiving funnel, preventing it from being attached to other equipment and adversely affecting the equipment when the vibrator vibrates, thereby improving the device's practicality.
