Further, when the cleaning piece is limited in the tail bin and does not need cleaning, the cleaning moving block moves downwards through the downward rotation of the first cleaning connecting rod, so that one end of the second cleaning connecting rod, which is horizontally connected with the cleaning block mounting rod, moves horizontally towards the direction close to the rotating shaft, and the cleaning block is folded. When the cleaning piece extends into the minced steak bin and needs to clean the minced steak bin, the first cleaning connecting rod rotates upwards, and the cleaning moving block moves upwards, so that one end, connected with the cleaning block mounting rod, of the second cleaning connecting rod horizontally translates towards the direction of a position far away from the rotating shaft, and the cleaning block is unfolded until the cleaning block is contacted with the inner side wall of the minced steak bin. Therefore, the cleaning block can be flexibly adjusted to be folded or unfolded according to the actual use of the cleaning piece, and the cleaning block is prevented from being folded or unfolded in a fixed connection mode, for example, the cleaning block mounting rod is directly welded on the rotating shaft through the welding rod, so that the cleaning block is always stretched to occupy the space position of the tail bin in a non-use state, and the tail bin needs a larger inner diameter size; the foldable or unfoldable cleaning block can be folded at a position close to the rotating shaft when extending into the meat grinding bin and is not cleaned, and can be specifically hidden below the base, so that the probability of fluid sprayed from the upper part polluting the upper part is reduced.

Further, the blade sets up on the sleeve, and the sleeve cover is established in the outside of axis of rotation and with axis of rotation sliding fit, still includes reset spring, presses the cover, presses cover and axis of rotation screw-thread fit, twists down and to press the cover and can drive the sleeve and move down to reset spring tensile deformation. Two ends of the reset spring can be respectively connected with the sleeve and the rotating shaft. So, when needs discharge the minced meat mud of mincing in the minced meat storehouse, can upwards twist earlier and press the cover, cause the sleeve to upwards shift out the minced meat storehouse in advance under the effort that reset spring resets, make things convenient for the staff to pass through the manual removal of discharge gate with the minced meat mud of mincing in the minced meat storehouse safely.

Namely, when meat is minced, the blade 132 is limited in the minced steak bin 122, and the cleaning piece 15 and other cleaning devices such as a spray head for spraying clear water or cleaning liquid do not interfere with the minced steak bin 122, so that the minced steak function of the minced steak bin 122 is fully met, and the minced steak process is fully carried out; in the cleaning stage, residual materials (meat mud) on the inner wall of the minced steak bin 122 are scraped out by utilizing the acting force between the ascending motion of the integral structure and the inner wall of the minced steak bin 122, so that the initial cleaning of the inner wall of the minced steak bin 122 is realized while the ascending motion of the integral structure is realized, when the first movable disc 134 and the second movable disc 135 are respectively opposite to the first notch 1211 and the second notch 1212, the cleaning point positions of the first movable disc 134, the second movable disc 135 and the blade 132 are limited in the cleaning bin 121, and the sequential realization of cleaning after the residual materials on the inner wall of the minced steak bin 122 are scraped out is realized; and after blade 132 left minced steak storehouse 122, preceding hidden cleaning piece 15 in tail storehouse 123 stretched into minced steak storehouse 122, and the rotation of reuse axis of rotation 131 washs the oil stain etc. on the inner wall in minced steak storehouse 122, reaches the clean effect of secondary, greatly guarantees the clean degree in minced steak storehouse 122 and has improved the integrated compactness of device. As one of the core technical features of the present invention, the base 133, the first movable plate 134, and the second movable plate 135 are spliced into an integral structure, which eliminates the manner of fixing the chassis in the prior art, and the height adjustment device 14 is used to drive the integral structure to move up and down, and the first movable plate 134 and the second movable plate 135 are horizontally movably spliced to realize the vertical movement and the horizontal separation and combination movement of the first movable plate 134 and the second movable plate 135, and the vertical movement is used to realize the effect of scraping, and the horizontal separation movement is used to perform the scraping blanking and provide a space gap for the fluid blanking generated in the flushing stage, so that the process of scraping the residual material on the inner wall of the minced steak bin 122 and then cleaning is ensured. Because the cleaning limit of the blade 132, the first movable disc 134 and the second movable disc 135 is arranged in the cleaning bin 121, the cleaning bin 121 does not perform the material twisting function, the technical problem that the inherent sticky material exists on the inner wall of the meat mincing bin 122 does not exist on the inner wall of the cleaning bin, the cleaning of the blade 132 can be realized by spraying clean water or cleaning liquid to the blade 132 through the cleaning port 1213, the problem of inner wall spraying is not required to be considered, and the pertinence of the washing is ensured. By adopting the shell 12 with the space structure, the cleaning bin 121, the minced steak bin 122 and the tail bin 123 are distributed from top to bottom, so that the blanking can be conveniently realized and the functions of material pocket and translation blanking of the first movable disc 134 and the second movable disc 135 can be ensured during the actual operation.
