[0002] In fields such as grain processing and chemical raw material storage, the inner walls of raw material silos are prone to reduced effective volume and even blockage risks due to material adhesion and clumping. Traditional cleaning methods rely on manual high-altitude operations, which pose safety hazards and are inefficient. While existing automated cleaning robots can replace manual labor, they generally face the following technical challenges:

[0003] Cable management is difficult: When the robot moves, the cable is prone to friction or tangling with the edge of the compartment, which may cause the equipment to stop or the cable to break.

[0004] Insufficient positioning accuracy: The inner wall of the cone bucket is a conical curved surface, and the robot is prone to deviating from the cleaning path due to center of gravity shift or cable tension;

[0029] This utility model discloses a raw material silo cone cleaning robot.

[0030] According to the appendix Figure 1-4 As shown, the system includes a cleaning robot body 1 and a cable 2 connected to the cleaning robot body 1. The cable 2 enables the cleaning robot body 1 to move and clean the inner wall of the raw material silo cone. The cable 2 is connected to a positioning unit 3, which is installed at the top of the raw material silo cone and can move along the top opening of the raw material silo cone. The positioning unit 3 includes:

[0031] The fixing bar 31 is L-shaped, and its two ends are located at the top and inside of the raw material silo cone, respectively.

[0032] The movable bar 32 is connected to the end of the fixed bar 31 and is located on the outside of the raw material silo cone.

[0033] Two traveling wheels 33 are respectively installed at the ends of the fixed bar 31 and the moving bar 32, and the two traveling wheels 33 are respectively attached to the inner and outer walls of the raw material silo cone.

[0034] Linear bearing 35 is installed on the outside of fixed bar 31 and movable bar 32, and cable 2 is movably inserted into the inside of linear bearing 35.

[0035] The linear bearing 35 and the walking wheel 33 of the positioning unit 3 work together to achieve physical isolation between the cable 2 and the edge of the silo opening, preventing the cable 2 from getting tangled and worn. The L-shaped fixing strip 31 and moving strip 32 of the positioning unit 3 are installed across the silo opening, and the two walking wheels 33 are in contact with the top of the silo to ensure that the robot walks along the preset path.

[0036] Furthermore, the main body 1 of the cleaning robot includes a body 11, a moving wheel 12 and a cleaning brush 13. The cable 2 is fixedly connected to the end of the body 11, the moving wheel 12 is installed on the outside of the body 11, and the cleaning brush 13 is installed on the other end of the body 11.

[0037] Furthermore, the machine body 11 is equipped with a drive motor for rotating the cleaning brush 13.

[0038] The drive motor drives the cleaning brush 13 to rotate, and combined with the movement of the two walking wheels 33 in the positioning unit 3, it achieves full coverage cleaning of the inner wall of the cone bucket.

[0039] Furthermore, multiple linear bearings 35 are provided, with two linear bearings 35 respectively installed above the fixed bar 31 and above the movable bar 32, and another linear bearing 35 installed on the outside of the fixed bar 31.

[0040] Preferably, an adjustment component 34 is provided between the fixed bar 31 and the movable bar 32. The adjustment component 34 can adjust the relative distance between the fixed bar 31 and the movable bar 32. The adjustment component 34 includes:

[0041] The threaded rod 341 is threaded inside the fixed bar 31 and rotatably connected to the movable bar 32;

[0042] Knob 342, threaded rod 341 passes through moving bar 32 and is fixedly connected to knob 342.

The positioning roller 37 at the end of the bracket 36 contacts the top of the silo, thus completing the fixing of the positioning unit 3.

[0046] Cable 2 passes sequentially through the linear bearing 35 on the outside of the fixed bar 31, the linear bearing 35 above the moving bar 32, and the linear bearing 35 above the fixed bar 31, forming a triple guide channel. The drive motor drives the cleaning brush 13 to rotate, and the moving wheel 12 moves along the inner wall of the cone bucket. Cable 2 moves synchronously with the robot through the positioning unit 3. The moving wheel 33 of the positioning unit 3 rolls along the edge of the bin opening to ensure that cable 2 has no direct contact with the bin opening.

[0047] For different silos, the distance between the fixed bar 31 and the moving bar 32 is adjusted by the knob 342. The guide rod 344 slides in the guide ring 343 to keep the positioning unit 3 structurally stable. After cleaning, the robot returns to the silo opening, and the cable 2 is orderly recycled through the positioning unit 3 to avoid tangling.
