DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the invention more clearly understood, the invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figures 1 to 10 As shown, the present invention provides a meat mincing device, including a meat mincing box 1, in which a driving device is arranged, a conical feed port 2 is arranged on the top of the meat mincing box 1, a slicing assembly 3 and a mincing assembly 5 are arranged in the meat mincing box 1, the slicing assembly 3 is arranged just below the conical feed port 2, the mincing assembly 5 is arranged below the slicing assembly 3, and the meat falls into the mincing assembly 5 after being chopped by the slicing assembly 3, the mincing assembly 5 includes a mincing box 501 fixed in the meat mincing box 1 and a spiral meat mincing rod 502 installed in the mincing box 501, the spiral meat mincing rod 502 is provided with a spiral cutter 503, the distance between two adjacent spiral cutters 503 decreases from the inside to the outside, one end of the spiral meat mincing rod 502 extends out of the meat mincing box 1, a detachable discharge barrel 6 is arranged outside the meat mincing box 1, the protruding part of the spiral meat mincing rod 502 is arranged in the discharge barrel 6, a detachable discharge plate 7 is fixed to the outer end of the discharge barrel 6, and a discharge hole 8 is opened on the discharge plate 7.

[0030] The conical feed port 2 increases the feed diameter, which is convenient for quick feeding. The meat is put into the meat grinder 1 from the conical feed port 2 and falls on the cutting assembly 3. The cutting assembly 3 is first used for cutting, and the large-volume meat or frozen meat is quickly cut into pieces. Then, the meat is gradually transported outward through the spiral meat grinder rod 502. During the transportation process, the meat is further ground from coarse to fine by the multi-stage spiral cutter 503. Under the push of the spiral meat grinder rod 502, the meat is finally squeezed out from the discharge hole 8. The detachable discharge barrel 6 is easy to clean, and the discharge plate 7 is detachable. The discharge plate 7 with different apertures can be replaced according to needs to adapt to different meat particle requirements.

[0031] As a preferred solution, the spacing between the spiral cutters 503 is divided into three gradients, and the spacing decreases from the inside to the outside to meet the mincing requirements.

[0032] like Figure 3 and Figure 4 As shown, the cutting assembly 3 includes a cutting box 301, a first cutting roller 302 and a second cutting roller 303. The cutting box 301 is fixed on the meat grinder 1. The first cutting roller 302 and the second cutting roller 303 are rotatably arranged in parallel on the cutting box 301 and the rotation directions of the two are opposite. The first cutting roller 302 includes a first rotating shaft 3021 and a plurality of first annular cutters 3022 fixed on the first rotating shaft 3021, and the plurality of first annular cutters 3022 are equidistantly arranged on the first rotating shaft 3021.

The second annular cutters 3032 are arranged between the two first annular cutters 3022, and the first annular cutter 3022 is arranged between the two second annular cutters 3032.

[0033] The cutting box 301 and the mincing box 501 are sealed up and down to prevent the meat from splashing out. The large pieces of meat are cross-cut by the first annular cutter 3022 and the second annular cutter 3032 to quickly form small pieces of meat or strips, which are convenient for the next step of mincing.

[0034] like Figure 6 As shown, the outer periphery of the first annular cutter 3022 is circular, and the outer periphery of the second annular cutter 3032 is provided with a sawtooth structure 3033.

The lower part of the scraper plate 402 is provided with equidistantly spaced long strip holes 403, and the two scraper plates 402 are symmetrically inclined inwardly, and the long strip holes 403 are penetrated by the first annular cutter 3022 or the second annular cutter 3032.

[0036] Since the meat material has a certain viscosity, the meat material may remain on the cutting assembly 3 when it is cut by the cutting assembly 3, blocking the gap between the cutting knives and affecting the cutting of the meat material behind. The scraper plate 402 is set between the first annular cutting knife 3022 and the second annular cutting knife 3032. When the cutting assembly 3 rotates, the meat material remaining in the gap between the annular cutting knives can be scraped off, so that the cutting assembly 3 can continue to work effectively. At the same time, the two scraper plates 402 are symmetrically inclined inward, which can guide the meat material to enter the cutting assembly 3 from the position between the two scraper plates 402, and the meat material that does not smoothly enter the cutting assembly 3 will rebound to between the two annular cutting knives after colliding with the scraper plates 402. Therefore, under the action of the two scraper plates 402, all the meat material entering from the conical feed port 2 will be cut by the cutting assembly 3.

[0037] As an implementation method, refer to Figure 4 The two ends of the scraper rod 401 are fixed on the cutting box 301.
