The connecting mechanism connects the two split parts in the form of bolt connection, which is convenient for installation and later disassembly and maintenance. The graphite ring 202 is arranged between the cleaning cylinder 2 and the rotating ring 6 and is Fastened and clamped, no connecting mechanism is required. The graphite ring 202 provides a circumferential sliding medium for the rotation of the rotating ring 6, and the structure is simple and not easy to damage; The spacer 11 is installed at the same time, and a foreign object removal device is installed between two adjacent spacer bars 11. The support frame 1 of the foreign object removal device is provided with a controller 8 and a distance sensor is provided on the end faces of both sides. 9. The signal output end of the distance sensor 9 is connected to the signal input end of the controller 8, and the signal output end of the controller 8 is connected to the control end of the first motor 401. After installation, the end of the foreign object removal device that is not provided with a cutting mechanism is adjacent to the interval The board 11 is installed, and when it needs to be started, the operator sends a start signal to the controller 8 through the mobile terminal, and then the first motor 401 and the second motor 501 are started, and the foreign object removal device moves along the transmission line 3 to the adjacent spacer bar 11 , when the distance sensor 9 on the side of the forward direction on the support frame 1 senses the occurrence of an obstacle, that is, the spacer bar 11, the signal is sent to the controller 8, and the controller 8 controls the first motor 401 to run in reverse, and the foreign object removal device When the distance sensor 9 on the side of the retraction direction senses that there is an obstacle, that is, the spacer 11, the signal is sent to the controller 8, and the controller 8 controls the first motor 401 to run in reverse again, that is, the first motor 401 when it was just started. In the original running direction, the foreign object removal device moves back and forth according to the above process. When it needs to stop, the operator sends a stop signal to the controller through the mobile terminal, and the foreign object removal device stops at the original position. In order to avoid the collision caused by the distance sensor 9 failure or work error A group of springs 12 are installed on both sides of the support frame 1, and each side is uniformly distributed in a ring.

In addition, a lithium battery is installed in the device , when the solar panel 10 cannot supply power, the lithium battery is used for power supply. When the solar panel 10 can generate electricity, the lithium battery is charged first, so as to avoid the situation that the device cannot work due to the lack of power caused by a long cloudy day. The setting of the mode saves the connection and setting of the power line for the device, and the design of the foreign object removal device in the present invention is simple and energy-saving.

In the traveling mechanism, the output end of the first motor 401 is connected to the shaft of a traveling wheel 4 in the traveling mechanism, and the other traveling wheel 4 is a driven wheel; the output end of the second motor 501 is connected to a shaft roller 502 in the cleaning mechanism , the ends of the brushes 503 of adjacent brush rollers cross each other, when the second motor drives one shaft roller 502 to rotate, the other three shaft rollers are driven by the mutual drive of the brushes 503 to rotate, so as to scrape the transmission line 3 The role of foreign matter on the surface; the walking mechanism is two groups and is arranged near the middle of the cleaning cylinder 2, and the cleaning mechanism is two groups and is respectively located near the two ends of the cleaning cylinder 2. Such a setting makes the cleaning cylinder 2 advance or retreat. The power transmission line 3 first passes through the cleaning mechanism and then passes through the running mechanism, which avoids the foreign matter affecting the normal operation of the running mechanism, and also avoids the phenomenon that the foreign matter is difficult to remove caused by the rolling of the walking wheel without passing through the cleaning mechanism; two groups of cleaning The mechanism shares four shaft rollers 502, and each shaft roller 502 is provided with brushes 503 near both ends, and the end of one of the shaft rollers 502 is a worm 504, and the output end of the second motor 501 is provided with a worm gear meshed with the worm 504 for transmission 505; the driving mechanism of the rotating ring 6 includes a ring rack 602 arranged inside the rotating ring 6 and a gear 603 arranged at the output end of the second motor, the ring rack 602 meshes with the gear 603, and the rotation of the gear 603 drives the ring gear The strip 602 rotates.

The cutting surface can not only realize the cutting function, but also can realize the drilling function. For example, if there is a carton hanging on the transmission line 3, the cutting surface can not only cut while advancing, but also can divide the carton from the middle to the periphery. The effect of the drill is formed, which avoids the phenomenon that it is difficult to remove the hanging objects only by the cutting action of the cutting knife, and significantly improves the function of the device to remove foreign objects, and achieves the purpose that cannot be realized in the prior art; in addition, the cutting The setting shape of knife 7 has also formed the shearing action to air, is equivalent to the blowing effect of fan, and the wind force that all cutting knife 7 shears air and forms is blown in the cleaning cylinder 2, and this wind force can clean the formed after cleaning mechanism. The sundries are blown out of the cleaning cylinder 2, which avoids the residual debris after cleaning and accumulates in the cleaning cylinder, and can maintain the cleaning effectiveness of the cleaning mechanism for a long time. Abnormal operation of various rotating parts.
