Description

Technical Field

[0001] The present application relates to the technical field of agricultural product processing, and in particular to a sweet corn threshing device. Background Art

[0002] Sweet corn is usually a kind of corn used for food production. Compared with ordinary corn, sweet corn tastes better and has higher nutritional value. Sweet corn usually has more moisture and softer kernels, while ordinary corn kernels are relatively hard. Therefore, when threshing sweet corn, traditional threshing devices may not be used, otherwise the corn kernels may be damaged.

[0003] Common corn threshing devices include manual corn planers, which are used to thresh corn by holding one hand.

[0004] Corn, and the other hand holds a manual corn planer from one end of the length of the corn to be threshed to the other end to scrape off the corn kernels to thresh the corn. However, manually holding the corn or the corn planer is not only labor-intensive but also the planer 23 is easy to accidentally injure the hands of the personnel. Therefore, there are also fixing devices for corn on the market, which do not require manual corn picking. For example, a fresh corn batch threshing device disclosed in the patent document with publication number CN208001573U can vertically place the corn in a cylinder, and the corn kernels are cut off by the downward movement of the annular blade above; for another example, a fresh corn threshing device disclosed in the patent document with publication number CN220733606U clamps the corn at both ends with fixed thorns, and then thres it through the threshing sheet at the bottom. However, the above two devices can only be adapted to corn ears with the same diameter at both ends when in use. Common corn ears generally have a smaller diameter at the end and a larger diameter at the tail. If the cutting device can only move in a straight line, the corn curve is not parallel to the planer movement trajectory, which may cause the corn kernels to be shredded or incomplete threshing. Utility Model Content

[0005] In order to avoid the problem that the corn curve is not parallel to the planer movement trajectory, which may cause the corn kernels to be planed or the threshing is incomplete, the present application provides a sweet corn threshing device.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A sweet corn threshing device comprises a receiving seat for placing corn to be threshed, one side of the receiving seat is rotatably connected to a rotating disk, the rotating disk is provided with a plurality of fixed cones equidistantly arranged around the central axis of the rotating disk, and the upper end of the receiving seat is provided with a telescopic member, the movable end of the telescopic member is provided with a mounting box, the interior of the mounting box is slidably connected to a mounting block, the bottom of the mounting block is provided with a planer for separating corn kernels from corn ears, and a spring is connected between the mounting block and the inner top wall of the mounting box, and the axial directions of the fixed cone and the telescopic member are parallel to the length extension direction of the receiving seat.

[0008] By adopting the technical solution, the planer can move up and down under the connecting action of the spring, so it is suitable for the situation where the diameters of corns are different.

[0009] Optionally, a limit rod is threadedly connected to the bottom of the installation box, and the limit rod is used to limit the descending position of the installation block.

[0010] By adopting the above technical solution, the planer is limited by the limiting rod, so that the blade of the planer can be adjusted to be aligned with the root of the corn kernel, which facilitates the threshing work.

[0011] Optionally, one end of the receiving seat away from the driving member is slidably connected to a support plate through a guide groove, and a clamping cone is provided on the support plate.

[0012] By adopting the above technical solution, the corn cob can be clamped conveniently through the cooperation of the clamping cone and the fixing cone, so that the threshing operation is more stable.

[0013] Optionally, the cone tips of the clamping cone and the fixing cone are arranged relative to each other, and the clamping cone is rotatably connected to the support plate.

[0014] By adopting the above technical solution, when the rotating disk drives the corn cob to rotate and change the granulating position, the clamping cone can rotate synchronously, which is smoother.

[0015] Optionally, a guide rod is provided on the movable end surface of the telescopic member, and the guide rod passes through the support plate and is slidably connected to the support plate.

[0016] By adopting the above technical solution, the telescopic member can be guided and supported, so that the telescopic member can drive the installation box to move linearly along the axial direction of the corn ear.

[0017] Optionally, a circular arc-shaped reserved groove is provided at the lower end of the planer, and the blade of the planer is serrated.

[0018] By adopting the above technical solution, the planer can fit on the surface of the corn cob through the reserved groove, and the serrated blade can reduce resistance, making it easier to cut corn kernels.

[0019] Optionally, a discharge trough extending to the outside of the receiving seat is opened inside the receiving seat, and the bottom inner wall of the discharge trough is inclined downward toward the output end of the discharge trough, and a leakage trough connected to the discharge trough is opened at the upper end of the receiving seat.

[0020] By adopting the above technical solution, the corn kernels that have been cut and dropped fall into the discharging trough for collection, and are discharged through the inclined surface at the bottom of the discharging trough, so as to facilitate collection and processing.

[0021] Optionally, a driving member is provided on the receiving seat, and an output end of the driving member is connected to the rotating disk.

[0022] By adopting the above technical solution, the driving member drives the rotating disk to rotate, so that the rotating disk drives the corn cob to rotate, so as to change the slicing position of the corn.

[0023] The spring enables the planer to move up and down inside the installation box. When the planer moves from the end with a smaller corn diameter to the end with a larger corn diameter, the planer can always contact the root of the corn kernel under the elastic force of the spring, thereby preventing the planer from moving in a single straight line, resulting in the corn kernels at the end with a smaller diameter not being threshed properly or the corn kernels at the end with a larger diameter being damaged during threshing, thus affecting the threshing effect.

[0024] By setting the fixed cone and the clamping cone, it is convenient to clamp the two ends of the corn, thereby improving the stability of the corn during threshing. At the same time, the driving part can rotate the rotating disk to drive the corn to rotate, so as to change the slicing position more conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] The embodiment of the present application discloses a sweet corn threshing device, comprising a receiving seat 1. When threshing corn, the corn is placed on the receiving seat 1 so that the axial direction of the corn is parallel to the length extension direction of the receiving seat 1. A rotating disk 11 is rotatably connected to one side of the receiving seat 1. The rotating disk 11 is provided with a plurality of fixed cones 12 equidistantly arranged around the central axis of the rotating disk 11, and the fixed cone 12 is inserted into the end of the corn with a larger diameter to fix the corn, so as to avoid the corn shaking during threshing and affect the threshing effect. A telescopic member 2 is provided at the upper end of the receiving seat 1, and a mounting box 21 is provided at the movable end of the telescopic member 2. A mounting block 22 is slidably connected to the inside of the mounting box 21. A planer 23 for separating corn kernels from corn ears is provided at the bottom of the mounting block 22, and a spring 24 is connected between the mounting block 22 and the inner top wall of the mounting box 21. The axial directions of the fixed cone 12 and the telescopic member 2 are parallel to the length extension direction of the receiving seat 1.

[0032] Specifically, when in use, first move the blade of the planer 23 to the end of the corn with a smaller diameter so that the blade is aligned with the root of the corn kernel. Then, the installation box 21 is driven to move by the telescopic member 2 to drive the planer 23 to move along the axis of the corn cob. As the diameter of the corn continues to increase, the planer 23 will continuously compress the spring 24 to move upward. Through the up and down elastic movement of the planer 23, the movement trajectory of the planer 23 is made parallel to the corn curve to achieve the removal of corn kernels. It is suitable for use with corn cobs of different diameters, wherein the telescopic member 2 can be a mechanism capable of linear motion, such as an electric telescopic rod.

[0033] Furthermore, a driving member 7 is provided on the receiving seat 1, and the output end of the driving member 7 is connected to the rotating disk 11. The driving member 7 can be a servo motor or other device that can drive the rotating disk 11 to rotate. When the telescopic member 2 drives the planer 23 to move from one end of the corn cob to the other end, the telescopic member 2 drives the planer 23 to reset. At this time, the telescopic member 2 completes a reciprocating stroke, and then the driving member 7 drives the turntable to rotate a certain angle to change the planing part of the corn cob, so that the blade of the planer 23 is aligned with the part of the corn cob where the particles have not been removed.

[0034] Furthermore, a circular arc-shaped reserved groove 5 is opened at the lower end of the planer 23, and the blade portion of the planer 23 is serrated, and the blade portion of the planer 23 is inclined, that is, there is a certain angle between the blade and the root of the corn kernel. The inclined blade can cut into the corn more effectively and improve the planing efficiency. The reserved groove 5 can make the planer 23 fit on the surface of the corn cob, and the serrated blade can reduce resistance and cut the corn kernels more easily.

[0035] Furthermore, the bottom of the mounting box 21 is threadedly connected to a limiting rod 3, which is used to limit the descending position of the mounting block 22. Before threshing, after aligning the blade of the planer 23 with the root of the corn kernel, the limiting rod 3 is rotated to make the top of the limiting rod 3 conflict with the mounting block 22, thereby conflicting with the lowest movement position of the mounting block 22, so that the mounting block 22 can only drive the planer 23 to compress the spring 24 and move upward, thereby cooperating with the planer 23 to move from the end with a smaller diameter of the corn cob to the end with a larger diameter, and when the planer 23 moves to the end with a smaller diameter of the corn cob again, due to the limiting effect of the limiting column, the planer 23 will not continue to move downward due to the elastic force of the spring 24, thereby aligning with the root of the corn kernel and waiting for the next cycle of threshing.

[0036] Furthermore, a discharge trough 6 extending to the outside of the receiving seat 1 is provided inside the receiving seat 1, and the bottom inner wall of the discharge trough 6 is inclined downward toward the output end of the discharge trough 6, and a leakage trough 61 connected to the discharge trough 6 is provided at the upper end of the receiving seat 1. The threshed corn particles fall into the discharge trough 6 through the leakage trough 61, and are discharged by the inclined bottom wall of the discharge trough 6, so as to facilitate the discharge of the threshed particles.

[0037] Furthermore, one end of the receiving seat 1 away from the driving member 7 is slidably connected to a support plate 41 through a guide slot 4, and a clamping cone 42 is provided on the support plate 41. The cone tips of the clamping cone 42 and the fixed cone 12 are arranged relatively to each other. After the end with a larger diameter of the corn cob is connected to the fixed cone 12, the clamping cone 42 is driven by the sliding support plate 41 to be inserted into the end with a smaller diameter of the corn cob, and the corn cob is clamped by cooperation with the fixed cone 12, thereby improving the stability of the corn during threshing and preventing the corn from falling off the receiving seat 1. In addition, corns of different lengths can be clamped by the position of the sliding support plate 41. There is a certain damping property between the support plate 41 and the guide slot 4. When the support plate 41 is slid, the force applied to the support plate 41 is greater than the friction between the support plate 41 and the guide slot 4, thereby preventing the support plate 41 from moving randomly.

[0038] Furthermore, the clamping cone 42 is rotatably connected to the support plate 41. When the rotating disk 11 drives the corn cob to rotate, the clamping cone 42 can be driven to move synchronously on the support plate 41, thereby preventing the clamping cone 42 from falling off from the end of the corn when the corn rotates.

[0039] Furthermore, a guide rod 43 is provided on the end face of the movable end of the telescopic member 2, and the guide rod 43 passes through the support plate 41 and is slidably connected to the support plate 41. The end of the telescopic member 2 can be supported and guided by the guide rod 43 to prevent the planer 23 from moving the movable end of the telescopic member 2 upward due to the upward force of the corn when the movable end of the telescopic member 2 is extended, thereby allowing the telescopic member 2 to maintain linear motion.

[0040] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
