[0033] The knocking mechanism 7 includes a mounting seat 71, a knocking arm 75, a knocking hammer 76 and a knocking driving member 73. The knocking driving member 73 can drive the knocking arm 75 to swing, and the knocking hammer 76 arranged on the knocking arm 75 performs a knocking action accordingly.

[0034] In some embodiments, one end of the knocking arm 75 is hinged to the mounting seat 71 , and a knocking hammer 76 is provided at the other end. When the knocking arm 75 swings back and forth relative to the mounting seat 71 , the knocking action of the knocking hammer 76 is realized.

[0035] The striking hammer 76 may be made of metal or alloy, such as copper, and will not generate sparks when colliding with the silo, thereby avoiding combustion of the combustible materials inside the silo and having an explosion-proof effect.

[0036] The knocking mechanism 7 is arranged on the mobile vehicle 2, and the mobile vehicle 2 can move on the ground or other supporting basis to move around the silo to be cleaned, so that different positions of the silo can be knocked by the knocking mechanism 7, that is, the outer wall surface of the silo is knocked by the knocking hammer 76, so that the dust attached to the inner wall surface of the silo is detached, so as to avoid or alleviate the accumulation of dust on the silo.

[0037] The mobile vehicle 2 may be driven by electricity, fuel, or the like.

[0038] In this solution, the silo cleaning device can move around the silo and knock the silo through the knocking mechanism, thereby achieving a more comprehensive knocking treatment of the silo, improving the cleaning effect, and saving manpower.

[0039] In some embodiments, the knocking drive member 73 is a telescopic drive member whose two ends are respectively connected to the mounting seat 71 and the knocking arm 75. The telescopic drive member can move telescopically to drive the knocking arm 75 to swing relative to the mounting seat 71 to achieve the knocking action. The telescopic drive member can be an oil cylinder, an air cylinder, an electric cylinder, etc. In other embodiments, the knocking drive member 73 can also be an electric motor, a hydraulic motor, etc.

[0040] In addition, in some embodiments, the knocking mechanism 7 further includes a sliding member 72 linearly movably disposed on the mounting seat 71 , and the sliding member 72 is connected to the knocking driving member 73 to guide the knocking driving member 73 to extend and retract along a straight line.

[0041] In some embodiments, the knocking mechanism 7 further includes a rocker arm 74 whose two ends are respectively hinged to the knocking arm 75 and the sliding member 72, and the mounting seat 71, the knocking driving member 73, the sliding member 72, the rocker arm 74 and the knocking arm 75 form a deformable polygonal structure. Figure 3As shown, the knocking arm 75 is provided with a section A, and its two ends are respectively hinged to the rocking arm 74 and the mounting seat 71, and the extension direction and the telescopic direction of the knocking driving member 73 are the same as the sliding direction of the sliding member 72 on the mounting seat 71, and the sliding member 72 can guide the movement of the rocking arm 74. When the knocking driving member 73 is telescopic, the sliding member 72 can be driven to slide back and forth relative to the mounting seat 71, thereby driving the rocking arm 74 to swing, and accordingly, the knocking arm 75 also swings, thereby realizing the knocking action of the knocking hammer 76. It can be seen that the knocking driving member 73 and the knocking arm 75 (a part) are arranged in a polygon, and the swing of the knocking arm 75 can be realized by the telescopic movement of the knocking driving member 73.

The installation process of the knocking hammer 76 can be: insert the knocking hammer 76 into the recessed portion of the knocking arm 75, and then insert the fixing pin 77 into the knocking arm 75 and the knocking hammer 76 to prevent the knocking hammer 76 from being disengaged, wherein the extension direction of the fixing pin 77 can be perpendicular to the insertion direction of the knocking hammer 76. The fixing pin 77 can pass through the knocking arm 75 and the knocking hammer 76 and extend from the other side, and a stop pin can be inserted into the extended portion to prevent the fixing pin 77 from being disengaged from the knocking arm 75 and the knocking hammer 76. When the knocking hammer 76 needs to be disassembled, the fixing pin 77 can be pulled out.

[0045] In some embodiments, the knocking mechanism 7 includes two knocking hammers 76 and two knocking arms 75 that are mirror-symmetrical to each other. When in use, when the mobile vehicle 2 is set on a horizontal plane, the two knocking arms 75, especially the two knocking hammers 76, are arranged at intervals in the horizontal direction, and can knock the silo at different positions in the horizontal direction.

The knocking mechanism 7 is disposed on the moving arm 61, and the transmission mechanism 63 can drive the moving arm 61 to move relative to the support arm 62 along the length direction of the moving arm 61. The knocking mechanism 7 is disposed at one end of the moving arm 61. When the transmission mechanism 63 drives the moving arm 61 to move relative to the support arm 62, the knocking mechanism 7 can be driven to extend or retract relatively. In some embodiments, the transmission mechanism 63 can include a motor, a chain, and a sprocket. When the motor is running, the sprocket can be driven to rotate by the chain. The moving arm 61 is provided with a rack that meshes with the sprocket and extends in the same direction as the moving arm 61. The rotation of the sprocket can drive the rack and the moving arm 61 to move relative to the support arm 62 along the length direction of the moving arm 61. Of course, in other embodiments, the transmission mechanism 63 can also include an oil cylinder, an air cylinder, etc., whose two ends are respectively connected to the moving arm 61 and the support arm 62. The support arm 62 may be substantially formed into a sleeve shape, and the moving arm 61 is disposed through the support arm 62 .

The guide mechanism 64 includes a plurality of rotatable guide rollers disposed on the support arm 62 and surrounding the movable arm 61. The movable arm 61 is clamped between the plurality of guide rollers. The relative movement of the movable arm 61 on the support arm 62 can be guided by the guide rollers, and the friction between the movable arm 61 and the support arm 62 can be reduced. The guide mechanism 64 and the transmission mechanism 63 can be spaced apart in the length direction of the support arm 62 to support the movable arm 61 at two different positions. For example, the sprocket and the guide roller support the movable arm 61 at different positions in the length direction. In the case where the cross section of the movable arm 61 is rectangular, guide rollers can be respectively disposed on the upper, lower, left and right sides of the movable arm 61 to support and guide the movable arm 61.
