[0030] In some embodiments, please refer to Figure 3 , Figure 4 , Figure 7The gear unit includes a driving gear 321 and a driven gear 322. The driving gear 321 is fixed on the output shaft of the motor 31. The driven gear 322 is rotatably mounted on the base 2. The peripheral teeth of the driving gear 321 mesh with the peripheral teeth of the driven gear 322, resulting in a more stable gear transmission connection.

[0031] The diameter of the driving gear 321 is smaller than that of the driven gear 322, which saves costs and reduces the space occupied.

[0032] Preferably, the driven gear 322 is configured as a ring structure, and the driven gear 322 has a mounting hole 3221 inside. One end of the cutter head is fixed in the mounting hole 3221 and is coaxially arranged with the driven gear 322, which makes reasonable use of space and reduces the size of the equipment.

[0033] For specific details and ease of installation, please refer to... Figure 3 , Figure 4 , Figure 5 , Figure 6 An annular locking cover 323 is provided on the upper surface of the driven gear 322. The locking cover 323 is screwed to the driven gear 322, and multiple mounting slots 3231 are provided on the inner side of the locking cover 323. The threshing disc 4 includes a blade body 41 and multiple mounting plates 42 connected to the periphery of the blade body 41. One end of the mounting plate 42 away from the blade body 41 is fixed in the mounting hole 3221, making installation and disassembly more convenient. Among them, four mounting plates 42 are provided, and the other end of the mounting plates 42 are inserted into the fixing slots reserved on the side of the blade body 41, which facilitates maintenance and replacement and saves costs.

[0034] In some embodiments, the threshing disc 4 further includes a protective sleeve 44 and a retaining ring 45. The protective sleeve 44 is configured as a cylindrical structure with open top and bottom. The end of the mounting plate 42 away from the locking cover 323 protrudes, and the retaining ring 45 is fitted onto the locking cover 323. The inner sidewall of the retaining ring 45 forms a groove with the protruding side of the mounting plate 42. One end of the protective sleeve 44 is engaged in multiple grooves, that is, the protective sleeve 44 is clamped by the retaining ring 45 and the protruding part of the mounting plate 42. The blade body 41 is located inside the protective sleeve 44, which facilitates installation and disassembly, and provides high assembly efficiency and safety.

[0035] Specifically, the retaining ring 45 is placed inside the first connecting plate 33, and the periphery of the retaining ring 45 is fitted and connected to the inner wall of the first connecting plate 33. Furthermore, the retaining ring 45 has two protruding lugs 451, and the first connecting plate 33 has two corresponding grooves, with the lugs 451 located within the grooves. The area of ​​the grooves is larger than the area of ​​the lugs 451, facilitating the installation and removal of the retaining ring 45 and making it more convenient to use.

[0036] For preferred options, please refer to [the provided text]. Figure 4 , Figure 5 , Figure 7 The drive assembly 3 also includes a first connecting plate 33, a second connecting plate 34, and multiple limiting gears 35. The first connecting plate 33 and the second connecting plate 34 are vertically spaced apart, and the gear seats of the multiple limiting gears 35 are all fixed between the first connecting plate 33 and the second connecting plate 34. Multiple limiting gears 35 are arranged around the driven gear 322 to fix the driven gear 322. The periphery of each limiting gear 35 is meshed with the driven gear 322. The multiple limiting gears 35 are used to limit the position of the driven gear 322, resulting in a more stable structure and higher installation accuracy.

[0037] Specifically, a limiting gear 35 is connected between the driving gear 321 and the driven gear 322, and the output shaft of the motor 31 is set vertically with a clearance setting, which makes better use of space.

[0038] Preferably, the gear seats of the multiple limiting gears 35 are connected to the first connecting plate 33 and the second connecting plate 34 by screws. The multiple limiting gears 35 clamp the driven gear 322 in the middle, reducing the number of mounting parts for the driven gear 322 and lowering the cost. The driven gear 322 is screwed to the locking member, facilitating the installation of the fixing ring 45 and the mounting plate 42. Thus, the multiple limiting gears 35, the driven gear 322, the locking member, and the driving gear 321 all rotate synchronously under the drive of the motor 31. Among them, the driving gear 321 has the same structure as the limiting gears 35, resulting in lower cost and more stable transmission.

[0039] In some embodiments, please refer to Figure 5 , Figure 6 , Figure 7 The threshing disc 4 is configured as a cylindrical structure with multiple blade teeth 43. The blade teeth 43 are spaced apart on the periphery of the blade body 41, and their thickness decreases along their axial direction. The outer surface of the blade teeth 43 is an inclined slope, and the inner surface of the blade teeth 43 is vertically oriented, thereby improving the threshing efficiency of corn.

[0040] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 The base 2 includes a protective frame 21, a support frame 22, and a base 23. The drive assembly 3 is disposed within the protective frame 21. Both the upper and lower surfaces of the protective frame 21 are provided with clearance holes for the threshing disc 4 to avoid obstruction. The side of the protective frame 21 away from the threshing disc 4 is connected to one end of the support frame 22, and the other end of the support frame 22 is fixedly connected to one side of the base 23. The motor 31 is located within the support frame 22. The structure is compact, lightweight, and highly stable.

[0041] Specifically, the first connecting plate 33 is screwed to the upper panel of the protective frame 21, and the second connecting plate 34 is screwed to the lower panel of the protective frame 21. The overall shape of the protective frame 21, the support frame 22, and the base 23 can be set as a U-shaped structure, which is more compact, reduces its own volume and weight, and saves costs.

[0042] During use, place the container for collecting corn kernels and corn cobs on the base 23 and align it with the discharge port for easy collection of threshed corn kernels. Manually place the corn on the blade of the threshing disc 4, start the motor 31, and the motor 31 drives the driven gear 322 and the threshing disc 4 to rotate via the drive gear 321 and the limit gear 35. While the threshing disc 4 is rotating, manually lower the corn onto the threshing disc 4 so that the blades 43 separate the corn kernels from the corn cobs. The threshed corn cobs fall out from the lower end of the blade body 41, and the corn kernels fall into the container through the gap between the protective sleeve 44 and the blade body 41, making it very convenient to use.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
