[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. The following description, with reference to the accompanying drawings, is provided to aid in understanding exemplary embodiments of the present invention as defined by the claims and their equivalents. It includes various specific details to aid understanding, but these are to be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, detailed descriptions of functions and structures well known in the art will be omitted to make the specification clearer and more concise. Example

[0018] like Figure 1-3 As shown, a hand-cranked corn thresher includes a corn kernel storage box 1, a fixing layer 2 on top of the corn kernel storage box 1, a top cover 3 on top of the fixing layer 2, a storage opening 11 on top of the corn kernel storage box 1, and a top cover inlet 31 in the middle of the top cover 3. A gear turntable 5 is located inside the fixing layer 2, with a through-hole 50 in the middle of the gear turntable 5. The top and bottom of the turntable hole 50 are respectively connected to the top cover inlet 31 and the storage opening 11. A rotating shaft 6, rotatable relative to the fixing layer 2, is also provided on the side wall of the fixing layer 2. One end of the rotating shaft 6 is provided with a drive gear 61, which meshes with a large gear ring 52 on the gear turntable 5. The other end of the rotating shaft 6 is connected to a drive handle 7 on the outside of the fixing layer 2. A planer blade 8, rotatable with the gear turntable 5, is also provided in the turntable hole 50.

[0019] The gear turntable 5 includes a turntable body 51 and a large gear ring 52 disposed on the lower outer side of the turntable body 51. The fixing layer 2 is provided with an upwardly protruding support ring 21. The bottom of the large gear ring 52 can be slidably supported on the support ring 21.

[0020] The bottom of the turntable body 51 is also provided with a limiting ring 53 that protrudes downward to the lower part of the large toothed ring 52, and the limiting ring 53 is located inside the supporting ring 21.

[0021] The turntable hole 50 is located in the middle of the turntable body 51. A plurality of turntable connecting parts 508 are provided on the side wall of the turntable hole 50. The planer 8 includes an annular planer part 81 for peeling corn kernels from the corn cob and a planer connecting part 82 located outside the planer part 81. The planer connecting part 82 is fixedly connected to the turntable connecting part 508.

[0022] The annular planer section 81 has a planer hole 80 in the middle for the corn cob to pass through.

[0023] The inner edge of the upper cover inlet 31 is provided with a guide ring 32 to guide the corn material into the turntable hole 50.

[0024] The fixing layer 2 is connected and fixed to the top of the corn kernel storage box 1 by a detachable snap-fit ​​structure.

[0025] The top cover 3 is fixed to the top of the fixing layer 2 by a detachable snap-fit ​​structure.

[0026] The corn kernel storage box 1 is a cup-shaped container made of a transparent and visible material.

[0027] The bottom of the corn kernel storage box 1 is provided with an anti-slip washer groove 10, and an anti-slip washer 4 is provided in the anti-slip washer groove 10.

[0028] According to this application, the hand-cranked corn thresher is used as follows: Align the corn kernels with the blade opening (i.e., the inlet 31 of the upper cover) and push them in. While holding the tail end of the corn and applying downward pressure, rotate the handle 7. During this process, the corn kernels detach from the cob and fall into the lower storage box 1. When the corn can no longer be threshed, remove the cob, turn the other end of the uncracked corn around, insert it into the blade opening, and repeat the above steps until the corn is threshed.

[0029] According to the hand-cranked corn thresher of this application, the blade 8 can be a simple cylindrical structure. When downward pressure is applied to the corn and the blade is rotated, the corn kernels are separated from the corn cob. Because cooked corn is relatively easy to peel, applying pressure is sufficient to remove it from the cob. The rotation of the blade allows it to perform axial scraping and axial cutting simultaneously, improving efficiency. Furthermore, it compensates for uneven pressure and local jamming that may occur when manually pressing the corn in, making the process of removing the corn kernels more even and smooth, further improving efficiency.

[0030] It should be noted that, on the one hand, the accompanying drawings of this application disclose a cylindrical planer blade. In practical applications, the structure of the planer blade can be further improved as needed. For example, a serrated structure can be added to the top of the planer blade, or the top of the planer blade can be designed with a zigzag structure to increase the cutting ability in the circumferential direction and reduce the downward pressure. On the other hand, the size of the planer blade can be changed as needed. For example, planers of different sizes can be designed to adapt to corn of different diameters. The connection structure of the planer blade can be designed to be detachable and allow for the replacement of planers of different diameters. Alternatively, different specifications of the complete machine can be designed to cope with usage scenarios with slightly larger workloads, avoiding frequent changes. Since there are no strict size requirements for obtaining corn kernels, a planer blade of a fixed size can also adapt to corn of a specific diameter. For example, corn with a diameter tolerance within ±3mm can be cut with the same planer blade, and the obtained corn kernels can all be used normally. As for the diameter difference between the head and tail of the corn itself, if more output is desired, the relatively smaller diameter head corn can be gradually cut by appropriate tilting when inserting the corn. If efficiency is desired, the corn kernels at the tip can be discarded.

[0031] According to the hand-cranked corn thresher of this application, the handle 7 can adopt a common rotating handle structure, as long as it can achieve the effect of rotating the shaft 6 by manual cranking. The specific structure can adopt the structure disclosed in the accompanying drawings of this application, or any other feasible structure that can achieve a similar effect. Alternatively, a structure in which the shaft 6 is driven by electricity or other means to drive the drive gear 61 to rotate can also be considered.

[0032] The hand-cranked corn kernel thresher of this application improves the efficiency of manually removing corn kernels and has a simple structure, making it suitable for use in homes or restaurants that consume small batches of corn kernels. Example

[0033] This embodiment, as another preferred embodiment, differs from Embodiment 1 only in that the blade of the planer 8 has a toothed portion 89 at its tip. The toothed portion 89 is used to cut the root of the corn kernel, making it easier to detach from the corn cob.

[0034] The present invention has been described in detail above. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.

[0035] Through the above description of the embodiments, those skilled in the art can clearly understand that this utility model is implementable. Of course, the situations listed above are merely examples, and this utility model is not limited thereto. Those skilled in the art should understand that other modifications or simplifications of the technical solutions of this utility model can be appropriately applied to this utility model and should be included within the scope of this utility model.
