[0021] In addition, the scraper 43 is tooth-shaped, that is, a groove is arranged between a plurality of teeth, by arranging the tooth-shaped scraper 43, the overall friction on the conveying roller 11 can be reduced, when the conveying roller 11 is entirely wrapped with ice or ice layer, the ice layer can be better broken through and the ice can be removed, the scraper 43 is arranged on the buffer plate 42 in a sliding manner, the buffer plate 42 is rotatably arranged with a rotating rod 45, the rotating rod 45 is provided with an annular reciprocating groove 451, the scraper 43 is provided with a guide column 431 extending into the annular reciprocating groove 451, the two sides of the rotating rod 45 are provided with a driven gear two 44, when the cleaning seat 41 is pressed by the movable rack two 33 and close to the conveying roller 11, the driven gear two 44 can be engaged with the driving gear 13, at this time, the rotating rod 45 rotates and cooperates with the annular reciprocating groove 451 and the guide column 431 arranged on the scraper 43, so as to make the scraper 43 reciprocate horizontally, further cooperating with the tooth-shaped scraper 43 to remove the ice or ice layer on the outer circumferential surface of the conveying roller 11.

[0022] Working principle: when working, the conveying roller 11 rotates to drive the conveying belt 12 to move, and then the agricultural products are conveyed to the freezing area for quick freezing. When the conveying roller 11 accumulates ice on the outer periphery, the force of the conveying roller 11 at different positions on the conveying belt 12 is unbalanced, which causes the conveying belt 12 to deviate, and the protective side plate 21 in the corresponding direction is pressed and the spring 24 is compressed. At this time, because the sliding plate 251 is arranged on the movable rack 25, the protective side plate 21 on the opposite side remains stationary, the leakage plate 23 arranged on the protective side plate 21 can cover the gap generated by the deviation of the conveying belt 12, preventing the agricultural products from falling into the conveying main body 1, and ensuring the stable work of the conveying main body 1. After the movable rack 25 moves, the driven gear 32 is driven to rotate, which drives the movable rack 33, and the two groups of cleaning seats 41 are pushed to move towards the conveying roller 11. The buffer plate 42 can reduce the extrusion force between the scraper 43 and the conveying roller 11. After the driven gear 44 moves with the cleaning seat 41, it is in contact with and engaged with the driving gear 13. At this time, the driven gear 44 drives the rotating rod 45 to rotate, and under the cooperation of the annular reciprocating groove 451 and the guide column 431, the scraper 43 is reciprocated in the direction of the cleaning seat 41 to clean the ice or ice layer on the outer periphery of the conveying roller 11, so as to solve the imbalance of the driving force of the conveying belt 12 at different positions of the conveying roller 11. Finally, because the conveying belt 12 has no additional force to drive it to extrude the protective side plate 21, the compressed spring 24 is reset and the conveying belt 12 is corrected, realizing the automatic cleaning and correction of the whole equipment.
