[0001] This utility model relates to the technical field of corn processing equipment, and in particular to a single-ear corn thresher. Background Technology

[0002] Maize is one of the most important food crops globally, especially in developing countries where it is a staple food for many people and has significant research value. After the corn cob matures, the kernels need to be removed for consumption, further processing, or research.

[0003] In related technologies, current single-ear threshers generally require users to hold the corn cob by hand to thresh the corn, which is physically demanding and can easily lead to hand injuries. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a single-ear corn thresher, which simplifies user operation and reduces the risk of hand injury.

[0005] According to an embodiment of the present invention, a single-ear corn thresher includes: a base; a clamping assembly including a reciprocating drive, a first clamp and a second clamp arranged left and right, wherein a clamping space for placing corn cobs is constructed between the first clamp and the second clamp, the first clamp and the base are slidably connected in the left and right direction, the reciprocating drive is connected to the base and is drively connected to the second clamp, the reciprocating drive is used to drive the second clamp to move left and right; and a threshing assembly including a rotating cylinder and a rotary drive, wherein the rotating cylinder is coaxially arranged with the first clamp and rotatably connected to the base, the rotary drive is connected to the rotating cylinder to drive the rotating cylinder to rotate, and the rotating cylinder has a plurality of threshing teeth arranged circumferentially near the inner circumference of the second clamp.

[0006] The single-ear corn thresher according to an embodiment of the present invention has at least the following beneficial effects: the clamping assembly includes a first clamp and a second clamp arranged left and right, wherein the first clamp is slidably connected to the base in the left and right direction, and the reciprocating drive is connected to the base and drivenly connected to the second clamp to drive the second clamp to move left and right, so that the second clamp moves closer to or further away from the first clamp. The user can control the first clamp to move further away from the second clamp, thereby increasing the clamping space between the first clamp and the second clamp. Then the user can place the corn cob in the clamping space, and the first clamp and the second clamp can respectively clamp the two ends of the corn cob along its length direction. The rotating cylinder is coaxially arranged with the first clamp and rotatably connected to the base. The reciprocating drive can drive the second clamp to move closer to the first clamp, so that the corn cob moves from right to left and can abut against the threshing teeth. At the same time, the rotary drive can drive the rotating cylinder to rotate. Through the rotation of the rotating cylinder, the corn cob can be threshed. This single-ear corn thresher can automatically clamp the corn cob to be threshed through the clamping component, so that the user does not need to hold the corn cob at all times. Through the cooperation of the reciprocating drive and the rotary drive, the corn cob can be threshed, which can effectively reduce the risk of hand injury to the user. This single-ear corn thresher can be used in laboratories.

[0007] According to some embodiments of the present invention, a pin is provided on the facing surfaces of the first clamp and the second clamp, and the axial direction of the pin is consistent with the axial direction of the first clamp or the second clamp.

[0008] Specifically, pins are provided on the facing surfaces of the first and second clamps, and the axial direction of the pins is consistent with the axial direction of the first or second clamp. When the corn cob is placed between the first and second clamps, pressure can be applied to the corn cob through the first and second clamps, so that the pins are inserted into the end of the corn cob. This helps to improve the stability of the clamping assembly in holding the corn cob and helps to avoid the problem of the corn cob falling off during the threshing process.

[0009] According to some embodiments of the present invention, multiple teeth are provided on the facing surfaces of the first clamp and the second clamp, and the multiple teeth are arranged around the ejector pin.

[0010] Specifically, the first and second clamps are provided with multiple teeth on their facing surfaces, and the teeth are arranged around the ejector pin. When the corn cob is placed between the first and second clamps, the first and second clamps can apply pressure to the corn cob through the teeth and the ejector pin, so that the ejector pin and teeth can be inserted into or abutted against the end of the corn cob. This helps to improve the stability of the clamping assembly in holding the corn cob and helps to prevent the corn cob from falling off during the threshing process.

[0011] According to some embodiments of the present invention, the single-ear corn thresher also includes a spring and a guide rod. The two ends of the spring are respectively connected to the first clamp and the base. One end of the guide rod is connected to the first clamp, and the other end extends out of the base.

[0012] Specifically, the two ends of the spring abut against the first clamp and the second clamp respectively. By compressing or relaxing the spring, the first clamp can be driven to slide left and right relative to the clamp, thereby increasing or decreasing the clamping space, or cooperating with the movement of the second clamp to realize the left and right sliding of the corn cob relative to the threshing assembly. One end of the guide rod is connected to the first clamp, and the other end is set through the base. The setting of the guide rod can guide the sliding of the first clamp, which helps to make the sliding of the first clamp more stable and can effectively limit the rotation of the first clamp.

[0013] According to some embodiments of the present invention, the single-ear corn thresher also includes a limiting block, the base is provided with multiple guide holes, multiple guide rods are provided, the multiple guide rods are parallel to each other, the guide rods pass through the guide holes, and one end of the multiple guide rods that passes through the base is connected to the limiting block.

[0014] Specifically, the single-ear corn thresher also includes a limiting block, a base with guide holes, multiple guide holes, and multiple matching guide rods. Each guide rod corresponds to a guide hole and passes through the guide hole. The sliding connection between the multiple guide rods and the guide holes helps to improve the sliding stability of the first clamp and restricts the rotation of the first clamp. Combined with the rotation of the rotating cylinder relative to the corn cob, the corn cob is threshed.

[0015] According to some embodiments of the present invention, the single-ear corn thresher also includes a cover plate, and the base is provided with an upward-facing cavity. The first clamp, the second clamp, and the rotating cylinder are all located in the cavity. The cover plate is movably connected to the base to open and close the cavity.

[0016] To facilitate the collection of corn kernels and prevent them from scattering, this single-ear corn thresher also includes a cover plate. The base has an upward-opening cavity, and the first clamp, the second clamp, and the rotating cylinder are all located inside the cavity. The cover plate is movably connected to the base. Users can open the cavity through the cover plate, place the corn cob into the cavity, and position the corn cob between the first and second clamps. After closing the cavity with the cover plate, the corn cob can be threshed, ensuring that the threshed corn kernels are collected inside the cavity.

[0017] According to some embodiments of the present invention, the single-ear corn thresher also includes a collection box, which is placed at the lower end of the base to receive the fallen corn kernels.

[0018] Specifically, the single-ear corn thresher also includes a collection box, which is placed at the lower end of the base. Under the constraint of the inner wall of the base, the threshed corn kernels gather downwards and are collected into the collection box, making it easier for users to collect the corn kernels and making the single-ear corn thresher simpler and more convenient to use.

[0019] According to some embodiments of the present invention, the single-ear corn thresher also includes a seat adjacent to the base, the seat being connected to the lower end of the base.

[0020] Specifically, the single-ear corn thresher is also equipped with a seat adjacent to the base. The seat allows the user to sit upright, so that the user can operate the clamping and threshing components in a seated position. The seat is connected to the lower end of the base, which helps to improve the connection stability between the seat and the base.

[0021] According to some embodiments of this utility model, the reciprocating drive is a cylinder.

[0022] Specifically, the reciprocating drive is a cylinder. By extending and retracting the cylinder, the second clamp can be driven to move closer to or further away from the first clamp, thereby clamping the corn cob and driving the corn cob closer to or further away from the threshing assembly.

[0023] According to some embodiments of this utility model, the rotary driver is an electric motor.

[0024] Specifically, the rotary actuator is a motor, which drives the rotating cylinder to rotate through a transmission connection between the motor and the rotating cylinder. Compared with the hand-cranked drive, this method helps reduce the user's labor intensity.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0041] Reference Figures 1 to 3 As shown, a single-ear corn thresher according to an embodiment of the present invention includes: a base 100, a clamping assembly 200, and a threshing assembly 300.

[0042] Reference Figure 1 , Figure 2 and Figure 3As shown, in order to facilitate the collection of corn kernels and avoid the problem of corn kernels scattering everywhere, the base 100 has an upward-facing cavity 110. The single-ear corn thresher also includes a cover plate 500, which is rotatably connected to the base 100. By rotating the cover plate 500 in the forward or reverse direction relative to the base 100, the cover plate 500 can be driven to open or close the cavity 110.

[0043] Reference Figure 1 , Figure 2 and Figure 3 As shown, the clamping assembly 200 includes a reciprocating driver 230, a first clamp 210 and a second clamp 220 arranged left and right, and the threshing assembly 300 includes a rotating cylinder 310 and a rotating driver 320. The first clamp 210, the second clamp 220 and the rotating cylinder 310 are all disposed in the cavity 110. The first clamp 210 is connected to the left wall of the cavity 110 and can be slidably connected to the base 100 in the left and right direction. The second clamp 220 is slidably connected to the right wall of the cavity 110. The reciprocating driver 230 is connected to the base 100, and the base 100 can provide support for the reciprocating driver 230. The reciprocating driver 230 is driven to the second clamp 220 to move the second clamp 220 closer to the first clamp 210, so that the second clamp 220 moves closer to or further away from the first clamp 210.

[0044] Reference Figure 1 , Figure 2 and Figure 3 As shown, the user can control the first clamp 210 to move away from the second clamp 220, thereby increasing the clamping space between the first clamp 210 and the second clamp 220. Then the user can place the corn cob in the clamping space, and the first clamp 210 and the second clamp 220 can respectively clamp the two ends of the corn cob along its length direction.

[0045] Reference Figure 1 , Figure 2 and Figure 3 As shown, the rotating cylinder 310 is coaxially arranged with the first clamp 210 and rotatably connected to the base 100. The rotating driver 320 is connected to the rotating cylinder 310 to drive the rotating cylinder 310 to rotate. The rotating cylinder 310 has a plurality of threshing teeth 311 arranged in a circle near the inner circumference of the second clamp 220.

[0046] Reference Figure 1 , Figure 2 and Figure 3As shown, the user can control the reciprocating drive 230 to move the second clamp 220 closer to the first clamp 210, causing the corn cob to move from right to left so that it can abut against the threshing teeth 311. At the same time, the rotary drive 320 can drive the rotating drum 310 to rotate. Through the rotation of the rotating drum 310, the corn cob can be threshed. This single-ear corn thresher can automatically clamp the corn cob to be threshed through the clamping component 200, eliminating the need for the user to hold the corn cob at all times. Through the cooperation of the reciprocating drive 230 and the rotary drive 320, the corn cob can be threshed, which can effectively reduce the risk of hand injury to the user. This single-ear corn thresher can be used in laboratories.

[0047] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, in order to ensure the smooth rotation of the rotating cylinder 310 and the base 100, the single-ear corn thresher also includes a rotating bearing. The inner circumference of the rotating bearing is connected to the outer circumference of the rotating cylinder 310, and the outer circumference of the rotating bearing is connected to the inner wall of the cavity 110. The rotating bearing connects the rotating cylinder 310 and the base 100 to improve the rotational stability of the rotating cylinder 310 relative to the base 100.

[0048] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the threshing teeth 311 are inclined relative to the axial direction of the rotating cylinder 310, and the threshing teeth 311 include a first end and a second end. The first end is fixedly connected to the rotating cylinder 310, and the second end extends toward the axis of the rotating cylinder 310. The width of the threshing teeth 311 gradually decreases from the first end to the second end. Under the premise of ensuring the connection stability between the threshing teeth 311 and the rotating cylinder 310, the threshing effect on corn cobs can be improved.

[0049] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that both the first clamp 210 and the second clamp 220 have a pin 221 on their facing surfaces. The axial direction of the pin 221 is consistent with the axial direction of the first clamp 210 or the second clamp 220, and is used to insert into the end of the corn cob.

[0050] Reference Figure 1 , Figure 2 and Figure 3 As shown, both the right end face of the first clamp 210 and the left end face of the second clamp 220 have ejector pins 221. The taper of the ejector pin 221 located in the first clamp 210 is set towards the second clamp 220, and the taper of the ejector pin 221 located in the second clamp 220 is set towards the first clamp 210. The axial direction of the ejector pin 221 is consistent with the axial direction of the first clamp 210 or the second clamp 220.

[0051] Reference Figure 1 , Figure 2 and Figure 3 As shown, when the corn cob is placed between the first clamp 210 and the second clamp 220, the user can apply pressure to the corn cob through the first clamp 210 and the second clamp 220, so that the ejector pin 221 is inserted into the end of the corn cob, which helps to improve the stability of the clamping assembly 200 in clamping the corn cob and helps to avoid the problem of the corn cob falling off during the threshing process.

[0052] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the first clamp 210 and the second clamp 220 are provided with a plurality of teeth 222 on their facing surfaces. The plurality of teeth 222 are arranged around the ejector pin 221 and are used to abut against the end of the corn cob.

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown, both the right end face of the first clamp 210 and the left end face of the second clamp 220 have multiple teeth 222. The tips of the teeth 222 located at the first clamp 210 are set towards the second clamp 220, and the tips of the teeth 222 located at the second clamp 220 are set towards the first clamp 210. The length of the teeth 222 is less than the length of the pin 221. The pin 221 can be inserted into the end of the corn cob, and the teeth 222 can abut against the end of the corn cob.

[0054] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the first clamp 210 and the second clamp 220 are provided with multiple teeth 222 on their facing surfaces, and the multiple teeth 222 are arranged around the ejector pin 221. That is, when the corn cob is placed between the first clamp 210 and the second clamp 220, the first clamp 210 and the second clamp 220 can apply pressure to the corn cob through the teeth 222 and the ejector pin 221, so that the ejector pin 221 and the teeth 222 are inserted into the end of the corn cob, which helps to improve the stability of the clamping assembly 200 in clamping the corn cob and helps to avoid the problem of the corn cob falling off during the threshing process.

[0055] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the single-ear corn thresher also includes a spring 420 and a guide rod 410. The two ends of the spring 420 are connected to the first clamp 210 and the base 100 respectively. One end of the guide rod 410 is connected to the first clamp 210, and the other end extends out of the base 100.

[0056] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the two ends of the spring 420 abut against the first clamp 210 and the second clamp 220 respectively. By compressing or relaxing the spring 420, the first clamp 210 can be driven to slide left and right relative to the clamp, thereby increasing or decreasing the clamping space, or cooperating with the movement of the second clamp 220, thereby realizing the left and right sliding of the corn cob relative to the threshing assembly 300. One end of the guide rod 410 is connected to the first clamp 210, and the other end is set through the base 100. The setting of the guide rod 410 can guide the sliding of the first clamp 210, which is conducive to making the sliding of the first clamp 210 more stable and can effectively limit the rotation of the first clamp 210.

[0057] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the single-ear corn thresher also includes a limiting block 430, the base 100 is provided with multiple guide holes, multiple guide rods 410 are provided, the multiple guide rods 410 are parallel to each other, the guide rods 410 pass through the guide holes, and one end of the multiple guide rods 410 that passes out of the base 100 is connected to the limiting block 430.

[0058] Reference Figure 1 , Figure 2 and Figure 3 As shown, multiple guide holes are provided, and multiple guide rods 410 are provided accordingly. Each guide rod 410 corresponds to one of the guide holes, and the guide rods 410 pass through the guide holes. The sliding connection between the multiple guide rods 410 and the guide holes helps to improve the sliding stability of the first clamp 210 and can limit the rotation of the first clamp 210. In conjunction with the rotation of the rotating cylinder 310 relative to the corn cob, the corn cob threshing function is realized.

[0059] Reference Figure 1 , Figure 2 and Figure 3As shown, when it is necessary to place the corn cob between the first clamp 210 and the second clamp 220, the user can hold the limiting block 430 and pull the limiting block 430 away from the base 100, so that the first clamp 210 moves to the left. The first clamp 210 compresses the spring 420, and the clamping space between the first clamp 210 and the second clamp 220 increases, making it easier to place the corn cob into the clamping space. After the corn cob is placed into the clamping space, the user can slowly release the pulling force on the limiting block 430. Under the elastic action of the spring 420, the first clamp 210 moves closer to the second clamp 220, and the first clamp 210 and the second clamp 220 can clamp the corn cob together. After the corn cob is detached, the user can hold the limiting block 430 and pull the limiting block 430 away from the base 100 so that the first clamp 210 moves to the left, the first clamp 210 compresses the spring 420, and the clamping space between the first clamp 210 and the second clamp 220 increases, thereby removing the threshed corn cob from the cavity 110.

[0060] Reference Figure 1 , Figure 2 and Figure 3 As shown, it is understandable that in order to further improve the clamping stability of the corn cob corresponding to the first clamp 210 and the second clamp 220, the end face of the first clamp 210 near the second clamp 220 can be concave arc-shaped, and the end face of the second clamp 220 near the first clamp 210 is also concave arc-shaped. By fitting the end face of the first clamp 210 and the end face of the second clamp 220 with the curvature of the end of the corn cob, it is beneficial to improve the clamping effect of the corn cob and to avoid the problem of the corn cob separating from the first clamp 210 or the second clamp 220 due to radial pressure.

[0061] Reference Figure 1 , Figure 2 and Figure 3 As shown, it is understood that, specifically, the single-ear corn thresher also includes a collection box 600, which is placed at the lower end of the base 100. Under the constraint of the inner wall of the base 100, the threshed corn kernels gather downwards and are collected into the collection box 600, which makes it easier for users to collect the corn kernels and makes the use of the single-ear corn thresher simpler and more convenient.

[0062] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the lower end of the cavity 110 is connected to an inlet, and the drawer box 600 can enter and exit the inlet. When the drawer box 600 passes through the inlet, the receiving groove of the drawer box 600 is opposite to the threshing component 300, thereby guiding the threshed corn kernels to fall into the receiving groove to complete the collection of corn kernels.

[0063] Reference Figure 1 , Figure 2 and Figure 3 As shown, it is understood that, specifically, the single-ear corn thresher is also provided with a seat adjacent to the base 100. The seat allows the user to sit upright, so that the user can operate the clamping component 200 and the threshing component 300 in a seated position. The seat is connected to the lower end of the base 100, which helps to improve the connection stability between the seat and the base 100.

[0064] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that the reciprocating drive 230 is a cylinder. By extending and retracting the cylinder, the second clamp 220 can be driven to move closer to or further away from the first clamp 210, so as to clamp the corn cob and drive the corn cob to move closer to or further away from the threshing assembly 300.

[0065] It should be understood that in some other embodiments, the reciprocating driver 230 may be a linear drive mechanism such as an electric push rod, a lead screw and slider mechanism, or a crank-connecting rod mechanism.

[0066] Reference Figure 1 , Figure 2 and Figure 3 As shown, it can be understood that in this embodiment, the rotary driver 320 is a motor, and a gear is fixedly connected to the output end of the motor. An external gear ring is provided on the outer periphery of the rotating cylinder 310, and the external gear ring is meshed with the gear. The motor can drive the gear to rotate. Through the meshing connection between the gear and the external gear ring, the rotating cylinder 310 is driven to rotate. Through the contact between the threshing teeth 311 and the corn cob, the rotating cylinder 310 is driven to rotate, thereby realizing the threshing of the corn cob.

[0067] It should be understood that in some other embodiments, the single-ear corn thresher also includes a rocker arm, one end of which is connected to the rotating drum 310, and the other end of which extends out of the base 100. The user can manually drive the rotating drum 310 to rotate by rotating the rocker arm.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
