Description

Technical Field

[0001] This utility model relates to the field of corn ear threshing technology, and in particular to a micro corn single ear threshing machine for experimental use. Background Technology

[0002] The experimental miniature corn single-ear threshing machine is a miniaturized, high-precision threshing device designed specifically for laboratories or small-scale breeding scenarios. It is mainly used for threshing individual corn ears and can quickly separate the kernels from the cob of a single corn ear, replacing traditional manual threshing and greatly improving experimental efficiency.

[0003] Patent CN214508074U discloses a miniature corn single-ear threshing machine for experimental use, comprising a base, a support, and a shell. A fixing ring is fixedly connected to the inner side of the shell, and a threshing ring is located inside the fixing ring. The threshing ring and the fixing ring are coaxially arranged. Rollers are evenly distributed between the threshing ring and the fixing ring, with the outer sides of the rollers respectively fitting against the threshing ring and the fixing ring. Threshing teeth are fixedly connected at equal intervals to the inner side of the threshing ring. This threshing machine utilizes simple mechanical action to thresh single ears in the laboratory, solving the problem of mixing in corn experiments and breeding work. It threshes one ear at a time, is simple to use, and convenient. The threshing machine adopts a manual mechanical design, easily threshing corn kernels under the action of leverage. It is lightweight, weighing approximately 2 kg, and can be easily carried for immediate use. This threshing machine frees up manual labor for single-ear threshing, resulting in clean threshing.

[0004] In the above-mentioned patent, the inner diameter of the threshing ring is fixed during use, lacking an elastic adjustment structure, making it difficult to adapt to the differences in the size of individual corn ears, resulting in poor threshing adaptability. In addition, the feeding relies on manual pushing, requiring simultaneous control of two actions: "rotating the control lever" and "pushing the ear," which is difficult and can easily lead to fatigue during long-term operation, thus reducing threshing efficiency. Based on this, an experimental miniature corn single-ear threshing machine is proposed for improvement. Utility Model Content

[0005] In view of the fact that the above-mentioned devices are difficult to adapt to the differences in the size of individual ears of corn and that feeding relies on manual pushing, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a micro corn single ear thresher for experimental use, including a shell, a feeding port is provided on one side of the top of the shell, and a cavity is provided at one end of the interior of the shell. The shell includes a threshing mechanism for threshing and a feeding mechanism for feeding.

[0007] A first fixing plate is fixedly connected to the middle of the inner wall of the shell. A first toothed disc is rotatably connected to the inner wall of the first fixing plate. A first cone is fixedly sleeved inside the first toothed disc. A second fixing plate is provided on one side of the first fixing plate. A plurality of sliding grooves are opened inside the second fixing plate. Fixed teeth are slidably connected to the inner walls of the plurality of sliding grooves. A first spring is movably connected to the top of the fixed teeth. The top of the first spring is fixedly connected to the inner wall of the sliding groove. A third fixing plate is provided on one side of the second fixing plate. A second toothed disc is rotatably connected to the inner wall of the third fixing plate. A second cone is fixedly sleeved inside the second toothed disc. A plurality of threshing columns are provided on the inner walls of both the first and second cones. The inner diameter of the first cone is larger than the inner diameter of the second cone.

[0008] As a preferred embodiment, the housing is provided with a throttle at one end, a transmission rod is fixedly connected to one end of the throttle, a first gear is fixedly sleeved on the surface of the transmission rod, the surface of the first gear meshes with the surface of the second gear plate, and a second gear is also fixedly sleeved on the surface of the transmission rod, the surface of the second gear meshes with the surface of the first gear plate.

[0009] As a preferred embodiment, the inner wall of the feeding port is fixedly connected with several U-shaped rods, and the other end of the housing is provided with a pull plate.

[0010] As a preferred embodiment, a sliding rod is fixedly connected to one side of the pull plate, and auxiliary rods are symmetrically provided on one side of the pull plate. One end of the sliding rod and one end of the auxiliary rod are fixedly connected to the same push plate.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. This utility model, through the tapered gradient design of the first and second cones and the elastic adjustment of the fixing teeth, ensures that the corn cobs do not miss during threshing. On the one hand, it holds the corn cobs in place, preventing them from spinning freely as the first and second cones rotate. On the other hand, the relative movement between the fixing teeth and the threshing column creates a "scraping and squeezing" effect on the kernels on the surface of the corn cobs, thus achieving a matching clamping force and threshing force for corn cobs of different sizes during the threshing process. It can adapt to the size differences of corn cobs and achieve efficient threshing through gradual squeezing and friction, thus achieving adaptable operation.

[0016] 2. Through the design of the feeding mechanism, this utility model can complete the feeding preparation and pushing action simply by pulling and releasing the pull plate. It is easy to operate, reduces the errors that may occur when feeding manually, improves the efficiency and accuracy of threshing, and thus improves the overall reliability of the threshing machine.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-4The first embodiment of this utility model provides an experimental miniature corn single ear thresher, including a shell 1, a feeding port 11 is provided on one side of the top of the shell 1, and a cavity 12 is provided at one end of the interior of the shell 1. The shell 1 includes a threshing mechanism 2 for threshing and a feeding mechanism 3 for feeding.

[0025] A first fixing plate 21 is fixedly connected to the middle of the inner wall of the shell 1. A first toothed disc 22 is rotatably connected to the inner wall of the first fixing plate 21. A first cone 23 is fixedly sleeved inside the first toothed disc 22. A second fixing plate 24 is provided on one side of the first fixing plate 21. Several sliding grooves 25 are opened inside the second fixing plate 24. Fixed teeth 26 are slidably connected to the inner wall of the several sliding grooves 25. A first spring 27 is movably connected to the top of the fixed teeth 26. The top of the first spring 27 is fixedly connected to the inner wall of the sliding groove 25. A third fixing plate 28 is provided on one side of the second fixing plate 24. A second toothed disc 29 is rotatably connected to the inner wall of the third fixing plate 28. A second cone 210 is fixedly sleeved inside the second toothed disc 29. Several threshing columns are provided on the inner wall of the first cone 23 and the inner wall of the second cone 210. The inner diameter of the first cone 23 is larger than the inner diameter of the second cone 210.

[0026] One end of the housing 1 is provided with a throttle 211, and a transmission rod 212 is fixedly connected to one end of the throttle 211. A first gear 213 is fixedly sleeved on the surface of the transmission rod 212. The surface of the first gear 213 meshes with the surface of the second gear disk 29. A second gear 214 is also fixedly sleeved on the surface of the transmission rod 212. The surface of the second gear 214 meshes with the surface of the first gear disk 22.

[0027] During use, when it is necessary to thresh corn ears of different sizes, turn the handle 211. The handle 211 drives the transmission rod 212 to rotate synchronously. The transmission rod 212 drives the first gear 213 and the second gear 214 to rotate together. Since the inner diameter of the first cone 23 is larger than the inner diameter of the second cone 210, the corn ears will be gradually pushed to the direction with a smaller inner diameter by the feeding mechanism 3 in the conical space.

[0028] When the second gear 214 rotates, it drives the first gear disk 22 to rotate, which in turn causes the first cone 23 to rotate synchronously with the first gear disk 22. The rotation of the first gear 213 will drive the second gear disk 29 to rotate, which in turn causes the second cone 210 to rotate synchronously with the second gear disk 29. The first cone 23 and the second cone 210 drive several threshing columns to contact corn ears of different diameters, causing the kernels to fall off the cob.

[0029] As the corn cob moves toward the direction with a smaller inner diameter, it will compress the fixing teeth 26 inside the second fixing plate 24. After being compressed, the fixing teeth 26 will slide upward along the inner wall of the slide groove 25, while compressing the first spring 27. The reaction force of the first spring 27 keeps the fixing teeth 26 tightly attached to the surface of the corn cob. This, in conjunction with the threshing columns on the inner walls of the first cone 23 and the second cone 210, threshes the corn cob, further improving the threshing effect.

[0030] This design, through the tapered gradient design of the first cone 23 and the second cone 210, and the elastic adjustment of the fixed teeth 26, ensures that the corn cobs will not be missed during threshing. On the one hand, it can hold the corn cobs in place, preventing them from spinning freely as the first cone 23 and the second cone 210 rotate. On the other hand, the relative movement between the fixed teeth 26 and the threshing column can create a "scraping and squeezing" effect on the kernels on the surface of the corn cobs, thus achieving a matching clamping force and threshing force for corn cobs of different sizes during the threshing process. It can adapt to the size differences of corn cobs and achieve efficient threshing through gradual squeezing and friction, thus achieving adaptable operation.

[0031] Reference Figures 1-4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a number of U-shaped rods 31 are fixedly connected to the inner wall of the feeding port 11, and a pull plate 32 is provided at the other end of the housing 1;

[0032] A sliding rod 33 is fixedly connected to one side of the pull plate 32, and auxiliary rods 34 are symmetrically provided on one side of the pull plate 32. One end of the sliding rod 33 and one end of the auxiliary rod 34 are fixedly connected to the same push plate 35.

[0033] A sliding ring 36 is fixedly sleeved on the surface of the slide rod 33, and the sliding ring 36 is slidably connected to the inner wall of the cavity 12;

[0034] A second spring 37 is fitted on the surface of the slide rod 33, and the two ends of the second spring 37 are connected to one side of the slip ring 36 and the inner wall of the cavity 12, respectively.

[0035] During use, before the corn cob is put into the feeding port 11, the pull plate 32 is pulled first. The pull plate 32 will drive the slide rod 33 and the auxiliary rod 34 to move outward. At this time, the slip ring 36 on the surface of the slide rod 33 will slide synchronously along the inner wall of the cavity 12 and compress the second spring 37.

[0036] Next, corn cobs are placed into the feed inlet 11. Several U-shaped rods 31 will initially guide and limit the corn cobs. Then, the pull plate 32 is released, and the rebound force of the second spring 37 will push the slip ring 36 to reset. Then, the push plate 35 is moved towards the threshing area through the slide rod 33 and the auxiliary rod 34. After the push plate 35 contacts the corn cob, it pushes it into the threshing space between the first cone 23 and the second cone 210, thereby achieving the purpose of feeding.

[0037] This design, through the design of the feeding mechanism 3, allows the feeding preparation and pushing actions to be completed simply by pulling and releasing the pull plate 32. It is easy to operate, reduces the errors that may occur when feeding manually, improves the efficiency and accuracy of threshing, and thus enhances the overall reliability of the threshing machine.

[0038] Reference Figures 1-4 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a material collection tray 4 is slidably connected to the lower part of the inner wall of the shell 1, and the material collection tray 4 is located directly below the threshing mechanism 2.

[0039] During use, the corn kernels that fall after threshing will fall through the gaps between the first fixing plate 21, the second fixing plate 24 and the third fixing plate 28, and finally enter the collection tray 4 to complete the collection of corn kernels.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
