Two opposite inner walls of the movable groove 321 are respectively provided with a limit groove 323 extending along the vertical direction, and the upper side wall of the limit groove 323 is not communicated with the upper end surface of the movable rod 32. The lower ends of the two opposite side walls of the fixing rod 31 are respectively fixed with a limiting block 311, and the two limiting blocks 311 are respectively slidably disposed in the two limiting grooves 323. The stopper 311 and the stopper groove 323 play a role of guiding and limiting when the fixed lever 31 vertically moves, so that the fixed lever 31 is not completely separated from the movable lever 32.

As shown in fig. 1 and 3, the lifting member 4 includes a servo motor 41, a gear 42 fixedly connected to an output shaft of the servo motor 41, and a transmission gear 43 engaged with the gear 42, the transmission gear 43 is integrally formed on one side of the fixed rod 31 close to the gear 42 and extends along a length direction of the fixed rod 31, the movable rod 32 includes an abutting block 324 fixed on a side wall thereof, and the servo motor 41 is mounted on the abutting block 324. Can drive gear 42 when servo motor 41's output shaft rotates, and then drive driving gear 43 and dead lever 31 vertical movement for the whole length increase of landing leg 3 or reduce, the high emergence of feeding box 1 changes, and people can utilize earlier the lifting member 4 to reduce feeding box 1 before the material loading, thereby makes things convenient for the workman material loading of height.

As shown in fig. 1 and 3, two opposite side walls of the movable rod 32 are respectively provided with a fastening screw hole 325, the fastening screw hole 325 is located at the upper end of the movable rod 32 and is communicated with the movable groove 321, and a fastening bolt 326 is connected to the fastening screw hole 325 through an internal thread. After the fixing rod 31 is adjusted in place, the fastening bolt 326 is in threaded connection with the fastening screw hole 325 and then abuts against the fixing rod 31, so that the stability of the fixing rod 31 is further improved.

As shown in fig. 1, the pushing member 5 includes a connecting plate 51, a supporting base 52 located on one side of the connecting plate 51, and a pushing cylinder 53 mounted on the supporting base 52, the connecting plate 51 is fixed to two movable rods 32 far away from the cleaning machine body, and a piston rod of the pushing cylinder 53 is fixedly connected to the connecting plate 51. When the piston rod of the pushing cylinder 53 extends, the connecting plate 51 moves to one side close to the cleaning machine body, so that the end part of the inclined pipe 22 extends into the cleaning machine body, and nut blanking is facilitated.

The implementation principle of the embodiment is as follows: before the nut to be cleaned is poured into the feeding box 1, the piston rod of the driving cylinder 62 is extended, so that the baffle 61 rotates to one side far away from the mounting groove 222 and seals the opening of the guide pipe 2, and the pushing cylinder 53 is used for driving the connecting plate 51 to move to one side far away from the cleaning machine body, so that the guide pipe 2 is moved out of the cleaning machine body. Then, the output shaft of the servo motor 41 drives the gear 42 to rotate, and further drives the rack and the fixing rod 31 to move downwards, so that the length of the supporting leg 3 is reduced, and the height of the feeding box 1 is reduced. At this moment, the worker with a short height does not need to climb to a high position to pour materials by means of tools such as a crawling ladder, the operation is convenient, and the potential safety hazard is small. After the material is poured, firstly, the output shaft of the servo motor 41 rotates reversely and pushes the fixing rod 31 to move upwards, the length of the supporting leg 3 is increased, the feeding box 1 is lifted, then the pushing cylinder 53 is used for pushing the lower end of the inclined pipe 22 into the cleaning machine body, finally, the piston rod of the driving cylinder 62 is shortened, and the baffle 61 is rotated into the mounting groove 222 and the opening of the guide pipe 2 is opened.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
