DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] See attached Figure 1 To Attachment Figure 4 As shown, this embodiment provides a kudzu root crushing device, which includes a cylindrical shell 10, a hopper 20, a driving unit, a supply screw 30, a crushing assembly 40, a rotating cutting blade assembly 50 and a fixed cutting blade assembly 60.

[0024] The hopper 20 is fixedly mounted on the upper end of the housing 10, and the bottom end of the hopper 20 is connected to the inner cavity of the housing 10. The supply screw 30 is rotatably mounted in the inner cavity of the housing 10. The function of the supply screw 30 is to transport the kudzu root entering the hopper 20 to the front bolt. Figure 2 and attached Figure 4 As shown, in order to prevent the kudzu root from being entangled on the supply screw 30 during the forward conveying process through the supply screw 30, a plurality of supply protrusions 31 protruding outwards and arranged at intervals along the spiral direction are formed on the outer surface of the supply screw 30 in this embodiment, and an inclined surface 32 is formed on one side of the supply protrusion 31, so that after the kudzu root enters the supply screw 30, the kudzu root rotates with the supply screw 30 and is conveyed forward. At the same time, the crushing assembly 40 is formed on the inner wall of the housing 10, and the kudzu root is pressed and contacted with the crushing assembly 40 during the process of entering the next supply protrusion 31 from one supply protrusion 31 of the supply screw 30, and the crushing assembly 40 squeezes and preliminarily divides and shreds the kudzu root.

[0025] Combined with reference to Figure 5 and attached Figure 6As shown, in this embodiment, the crushing assembly 40 includes a plurality of crushing protrusions arranged on the inner wall of the housing 10 and extending radially, and the plurality of crushing protrusions are arranged at intervals along the circumferential direction of the inner wall of the housing 10, and each crushing protrusion extends from one end to the other end of the axial direction of the housing 10. When the kudzu root is conveyed forward with the feeding screw 30 rotating forward, the plurality of crushing protrusions sequentially contact the kudzu root and cut and crush the kudzu root for multiple times.

[0026] See attached Figure 2 and attached Figure 5 As shown, when the kudzu root is transported from one end of the inner cavity of the shell 10 to the other end by the supply screw 30, the rotating cutting blade assembly 50 and the fixed cutting blade assembly 60 installed at the other end of the supply screw 30 re-cut the kudzu root in the preliminary crushed state, and a discharge port 11 is formed at the bottom end of the shell 10, so that the kudzu root after re-cutting can be discharged through the discharge port 11.

[0027] See attached Figure 2 and attached Figure 3 As shown, the rotary cutting blade assembly 50 is fixedly mounted on the supply screw 30 at one end of the discharge port 11. The rotary cutting blade assembly 50 includes a plurality of rotary cutting blades. The plurality of rotary cutting blades are fixedly mounted on the supply screw 30 at uniform intervals along the circumferential direction. The rotary cutting blades rotate synchronously with the supply screw 30. The fixed cutting blade assembly 60 is mounted on the supply screw 30 at one end of the discharge port 11 through a bearing provided therein. The fixed cutting blade assembly 60 is fixedly mounted on the outer shell of the bearing through a locking bolt, and the fixed cutting blade assembly 60 is fixedly mounted adjacent to the outer side of the rotary cutting blade assembly 50. Similarly, the fixed cutting blade assembly 60 includes a plurality of fixed cutting blades 61 arranged at uniform intervals along the circumferential direction. The rotary cutting blade assembly 50 cooperates with the fixed cutting blade assembly 60 to cut and crush the kudzu root. That is, when cutting the kudzu root, the rotary cutting blade rotates with the supply screw 30, and the rotary cutting blade in a rotating state cooperates with the fixed cutting blade 61 in a fixed state to cut and crush the kudzu root. Refer to the attached Figure 7 As described above, in order to effectively prevent the fixed cutting blade 61 from shaking radially when cutting kudzu root, limiting bolts 70 are respectively installed at the left and right outer edges of the top of the fixed cutting blade 61. The pair of limiting bolts 70 are respectively in close contact with the left and right outer edges of the fixed cutting blade 61 to prevent the fixed cutting blade 61 from shaking.

[0028] See attached Figure 3As shown, in the axial direction, a blade fixing portion 90 is installed at the outer side of the fixed cutting blade assembly 60, and the blade fixing portion 90 is tightly fitted with the left outer edge of the fixed cutting blade assembly 60 to prevent the fixed cutting blade assembly 60 from moving outward. At the same time, a circular blade fixing part 80 is provided at the outer edge of the blade fixing portion 90, and the blade fixing part 80 is fixedly installed on the left end face of the shell 10 by bolts to press the blade fixing portion 90.

[0029] In order to better understand the kudzu root crushing device in this embodiment, the working principle thereof is briefly described below:

[0030] The driving unit provides power to the supply screw 30, and the supply screw 30 rotates at a specified speed. When the supply screw 30 rotates, the kudzu root in the hopper 20 is transported downward and enters the supply screw 30 without cutting off the kudzu root. At this time, while the supply screw 30 rotates, the supply protrusion 31 and the inclined surface 32 bite the kudzu root and enter, thereby realizing the supply. When the kudzu root is filled and supplied between the supply screw 30 and the inner wall of the shell 10, the crushing assembly 40 formed on the inner wall of the shell 10 is crushed multiple times and supplied to the inside through the supply screw 30. The kudzu root crushed in the inner cavity of the shell 10 while being transferred by the supply screw 30 is rotated by the rotating cutting blade rotating together with the supply screw 30, and the upper part of the fixed cutting blade 61 is stuck on the limit bolts 70 on both sides to maintain a fixed state. The supply screw 30 and the rotary cutting blade rotate in the same direction, so the discharged crushed kudzu root is cut by the rotation of the rotary cutting blade and discharged through the discharge port 11 below. The discharged kudzu root crushed material can be subsequently used to extract kudzu root juice using tools such as extractors and presses.

[0031] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
