[0017] Compared with the prior art, the utility model has the advantages of:

[0018] 1. The three-dimensional cleaning assembly of the cleaning mechanism is provided, which achieves efficient cleaning of the coal blocks adhered to the coal bin body in multiple dimensions. The rotating roller drives the brush rod to rotate and tightly adhere to the inner side wall, and the top end connecting rod tightly adheres to the inner top surface, so that the coal blocks on the side wall and the top surface can be synchronously removed. The bottom brush plate is connected with the rotating roller through the rotating plate and tightly adheres to the inner bottom surface when rotating with the rotating roller, forming a three-dimensional cleaning path of "top surface-side wall-bottom surface". This design of multiple components working together avoids the blind area of traditional single-path cleaning, achieves full inner wall cleaning without dead angles, and is especially suitable for complex scenarios where coal blocks are adhered due to moisture or static electricity.

The external PLC can control the motor speed to be periodically adjusted in the form of "fast-slow-fast-slow", which achieves dynamic optimization of cleaning efficiency and knocking effect. When rotating at high speed, the brush rod and the brush plate strip large-area adhered coal blocks at a high speed, improving the cleaning efficiency. When rotating at low speed, the line speed of the knocking block moving with the rotating roller is reduced, but the elastic connection of the spring generates a stronger impact force when contacting the side wall due to inertia, which is targeted to break the coal blocks adhered more firmly. This fast-slow alternating working mode ensures the cleaning speed and enhances the cleaning ability of stubbornly adhered objects, achieving the effect of energy saving and high efficiency.

[0020] 3. The elastic knocking structure of the spring and the knocking block is provided, which achieves flexible impact cleaning of the inner side wall of the coal bin. The fixed rod connects the knocking block through the spring. When the rotating roller rotates, the knocking block stretches the spring and hits the side wall under the action of centrifugal force. The elastic deformation of the spring can buffer the rigid impact and avoid damage to the bin body. At the same time, the reciprocating elastic force of the spring causes the knocking block to vibrate at a high frequency and a small amplitude, which continuously loosens the electrostatically adhered or caked coal blocks. This hard-soft combined knocking design is more protective than the traditional hard knocking, and can achieve uniform impact on the whole wall through the circumferential distribution of multiple knocking blocks, achieving the dual effects of efficient cleaning and equipment protection.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS
