As shown in fig. 5, 6, and 7, the grinding assembly 104 includes a dynamic grind 107, a static grind 108, and a shaft assembly 109. As shown in fig. 9A to 9E, the movable mill 107 includes a cylindrical movable mill body 70, a shaft coupling portion 74, a guide portion, and a crushing portion. In the embodiment shown in the figures, the material guiding portion and the pulverizing portion are integrated with the cylindrical movable grinding body 70. In the embodiment described later, it will be understood that all or part of the cylindrical movable grinding body 70, the shaft coupling portion 74, the guide portion, and the crushing portion may be separate pieces. The guiding part comprises two guiding blades 73 arranged on the inner wall of the cylindrical movable grinding body 70, wherein the guiding blades 73 can be spiral blades, and in another embodiment, the guiding blades can also be blades in other forms, and can play a role in axial flow pushing. The crushing portion includes a plurality of blades 71, 72 provided outside the cylindrical movable grinding body 70, both the blades 71 extending in the horizontal direction, and both the blades 81 being tilted in the horizontal direction. The inner wall of the cylindrical movable grinding body 70 is provided with movable grinding teeth 700 for grinding. The number of the blades 71, 72 may vary, for example, the crushing portion may include only two blades extending in the horizontal direction, or may be more than two blades.

At least one side of the blade has a cutting edge, only one side having a cutting edge is shown in fig. 9A-9E, and as shown in fig. 9D, the cutting edge 710 or 720 is oriented such that it facilitates pulling or pressing material downward and into the grinding assembly 104. The provision of upturned blades 72 also facilitates enhanced whipping efficiency. The main function of the blades 71, 72 is to pre-crush the material before it enters the grinding assembly 104, and the pre-crushed material re-enters the grinding assembly 104, which is beneficial to enhancing the anti-blocking function. As shown in fig. 9B, the flip angle a of blade 72 may be selected between 10 degrees and 25 degrees or between 0 degrees and 30 degrees. The edge of each blade may be blunt or sharp. In the embodiment with a preferable anti-blocking function, since the reversing operation is not required, the blade may be provided with the blade edge only on one rotation direction side. As can also be seen in fig. 9A-9E, the forward or reverse sides of the tips of each blade are rounded, and the edges or ridges on the blades are preferably rounded, which helps to maintain the flow pattern of the food material and reduces the resistance to entry into the grinding assembly.

The number of the two guide blades 73 of the guide portion may also be changed, and in order to increase the dynamic balance of the dynamic mill 107, the guide blades 73 are uniformly distributed or symmetrically distributed in the circumferential direction 360 degrees.

In a preferred embodiment, the connection between the upper and lower spiral surfaces of each spiral blade in the axial direction and the inner wall surface of the cylindrical movable grinding body 70 is provided with a transition fillet, so that the food can be extruded to the grinding area during feeding, the grinding speed of the food can be increased, meanwhile, accumulation is avoided, and the cleaning is convenient.

As shown in fig. 9F, the start end of each helical blade, that is, the upper helical surface of the portion protruding from the cylindrical movable grinding body 70 is provided as an arc surface 730, which also facilitates guiding the feed material. As shown in fig. 9C, a transition fillet 710 is also provided at the junction between the root of the blade 71 and the cylindrical movable grinding body 70, which also avoids accumulation of material and facilitates cleaning.

With continued reference to fig. 9A to 9F, the cylindrical movable grinding body 70 may be divided into an upper portion for providing the grinding teeth 700 and a lower portion serving as an annular support portion for the material guiding portion and the pulverizing portion, according to the functional area. In the embodiment shown in the drawings, the cylindrical movable grinding body 70 has a straight cylindrical upper portion and a tapered cylindrical lower portion. In one embodiment, the cylindrical movable grinding body 70 may be tapered or straight as a whole.

The flat hole 740 is penetrated by a flat head at the top end of the shaft 11 to realize molded surface connection, thereby the shaft 11 can drive the movable grinder 107, and the upper limit of the movable grinder 107 on the shaft 11 can be realized by the locking assembly 120 shown in fig. 6. The locking assembly may be a nut in one embodiment. The embodiment of the locking assembly as shown will be described in detail later. The lower limit of the movable mill 107 on the shaft 11 can be achieved by a shoulder on the shaft 11.

As shown in fig. 12 to 14, a locking assembly suitable for the foregoing embodiments and the embodiments described later includes a shaft 111 and a shaft end fixing assembly 30, where the shaft end fixing assembly 30 is mounted at the shaft end of the shaft 111. The shaft end fixing assembly 30 comprises a retaining ring 31 and a pressing sleeve, and the retaining ring 31 is elastically connected in the pressing sleeve. The upper part of the shaft 111 is provided with a fixing column 21, and the fixing column 21 adopts a thin cylinder with a diameter smaller than that of the transmission shaft. A ring-shaped convex step 22 is arranged on the outer wall surface of the fixed column 21, for example, the ring-shaped convex step 22 is arranged at the lower half section of the fixed column 21, and a retaining ring 31 is sleeved on the fixed column 21 and is buckled between the lower end surface of the step 22 and the outer wall surface of the fixed column 21. When the locking assembly is unlocked, the pressing sleeve is pressed downward, and the clasp 31 is spread apart, so that the clasp 31 is separated from the fixing post 21.

Preferably, the press kit includes a shaft end sleeve 32, an end cap 33, and a key 34. Fig. 6 is a perspective view of a shaft end sleeve of the locking assembly of the present invention.
