[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0025] As Figure 1 - Figure 2 shown, the present utility model provides a gear extrusion device for a meat grinder, including: a pre-cut orifice plate 2, a gear box 3, a driving gear 4, and a driven gear 5.

[0026] As Figure 1 shown, the pre-cut orifice plate 2 is installed in the reamer box 1 and is connected to the auger; the gear box 3 is connected to the pre-cut orifice plate 2, and the driving gear 4 is installed in the middle of the gear box 3; the driven gear 5 is located outside the driving gear 4 and meshes with the driving gear 4. The meat material of the present utility model is conveyed by the auger to the pre-cut orifice plate 2, and the meat material is crushed through the shearing action of the pre-cut orifice plate 2 and the gear. Moreover, the driving gear 4 drives the driven gear 5 to rotate. The closed volume of the gear on the side where the meshing is disengaged increases to form a feeding chamber, and the closed volume of the gear on the side where the meshing enters decreases to form a discharging chamber. The meat material is guided from the feeding chamber to the discharging chamber, and then the meat material is discharged from the side of the meat grinder to complete the processing of the meat material.

[0027] As Figure 2 shown, there are four driven gears 5, which are evenly distributed outside the driving gear 4. One driving gear 4 drives multiple driven gears 5 to rotate, greatly accelerating the working process and improving the shearing and extrusion efficiency of the meat material. Optionally, the module of the driving gear 4 and the driven gear 5 is 3 - 5, the pitch diameter of the driving gear 4 and the driven gear 5 is 70 mm - 80 mm, the addendum circle diameter of the driving gear 4 and the driven gear 5 is 75 mm - 90 mm, the base circle diameter of the driving gear 4 and the driven gear 5 is 75 mm - 80 mm, and the addendum circle pressure angle of the driving gear 4 and the driven gear 5 is 25 degrees - 45 degrees. Their appropriate sizes can fit perfectly, which is beneficial to the tooth-to-tooth meshing rotation and is convenient for maintaining the stable operation of the machine. In addition, the face contact ratio of the driving gear 4 and the driven gear 5 when meshing is 1.25 - 1.75, ensuring sufficient overlap between the driving gear 4 and the driven gear 5, maintaining their normal meshing, ensuring the normal operation of the driving gear 4 and the driven gear 5, and being beneficial to the normal operation of the meat grinding and meat material extrusion work.

[0028] The usage method of the present utility model is as follows:

[0029] 1. The auger conveys the meat to the pre-cut hole plate 2. At the same time, the auger generates pressure on the meat, so that the meat is discharged from the pre-cut hole plate 2 and conveyed to the driving gear 4 and the driven gear 5.

[0030] 2. When the driving gear 4 and the driven gear 5 rotate, the driving gear 4, the driven gear 5 and the holes on the pre-cut hole plate 2 produce a shearing effect, thereby chopping the meat into smaller pieces. At the same time, the meat enters along the side where the driving gear 4 and the driven gear 5 exit the meshing, and is discharged from the side where the driving gear 4 and the driven gear 5 enter the meshing, and then the meat is discharged from the side of the meat grinder, realizing the shearing and extrusion of the meat.

[0031] The utility model completes the chopping of meat material through the interaction between the pre-cut hole plate 2 and the gears, which is beneficial to the further processing of the meat material, and the meat material is guided from the side where the active gear 4 and the driven gear 5 exit the meshing to the side where the active gear 4 and the driven gear 5 enter the meshing, with multi-directional material discharge and complete material extrusion, and can realize both the meat grinding function and the meat material extrusion function through the gears in one step, avoiding the assembly of multiple parts, simplifying the operation process, simple and convenient installation, greatly speeding up the process of meat grinding, and being beneficial to saving resources and improving work efficiency.

[0032] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
