Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and more particularly to the technical field of a bidirectional clamping and feeding type corn single ear thresher. Background Art

[0002] Corn is my country's largest crop, accounting for 40% of total grain output and a key component of food security. Given the relative scarcity of corn germplasm resources, corn breeding research is crucial for ensuring national food security.

[0003] During the corn breeding process, it is necessary to thresh the ears of corn parents of different varieties in order to prepare for subsequent planting and breeding research. Manual threshing is time-consuming, labor-intensive and costly, so mechanical threshing is imperative. Existing corn ear threshers mostly use a vertical threshing drum with an adjustable threshing chamber to perform threshing by kneading at low speed rotation, which has a better threshing effect on corn ears with regular ears and uniform size. However, the ears of corn parents of different varieties vary in size and shape, and the existing single-ear threshers for corn cannot effectively address this feature, resulting in a low threshing rate and the occurrence of impurities. In addition, for corn ears with different moisture contents, traditional threshers are prone to kernel damage, which will cause losses to some already scarce samples and affect breeding efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a bidirectional clamping and feeding corn single-ear thresher to address the technical problems of traditional corn single-ear threshers, which mostly use a vertical threshing drum and an adjustable chamber for low-speed kneading threshing, poor applicability for threshing parent corn ears, low threshing efficiency due to the different sizes and shapes of corn ears, and mechanical damage to the kernels. This invention achieves efficient separation of corn kernels from the core shaft, improves threshing efficiency, and minimizes mechanical damage to the kernels.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] The present invention provides a bidirectional clamping and feeding type corn single ear thresher, comprising a box body, a feed port arranged on the top of the box body, a discharge port arranged on one side of the box body, and a core discharge port arranged on the other side of the box body. The box body is divided into an upper cavity and a lower cavity by a workbench. Clamping threshing devices are symmetrically arranged on the left and right sides of the upper cavity. An ear placement device is arranged between the two clamping threshing devices.

[0007] The box body also includes a top plate with a feed port on the top, a left plate and a right plate arranged on the left and right sides of the top plate, and a screen plate responsible for screening corn kernels and corn cobs is arranged obliquely in the lower cavity;

[0008] The clamping threshing device includes a first slide rail arranged horizontally inside the upper cavity, a clamping threshing shell slidably connected to the first slide rail through a slide rail seat, a first linear drive mechanism that drives the clamping threshing shell to reciprocate along the first slide rail, a clamping threshing module arranged at one end of the clamping threshing shell close to the fruit ear placement device, and a composite drive mechanism arranged in the clamping threshing shell to drive the clamping threshing module to move and rotate.

[0009] In one embodiment, a binocular camera is provided at one end of the clamping threshing shell near the ear placement device, and the binocular camera uploads the photographed corn to a computer to determine the size and axis diameter of the corn and monitor the operation status in real time.

[0010] In one embodiment, the clamping threshing module includes a cylindrical clamp housing fixed to the front end of the clamping threshing shell, three clamp arms and three tool arms, the clamp housing is axially arranged horizontally, and six radial grooves are opened at one end of the clamp housing close to the ear placement device. The three clamp arms and the three tool arms are cross-distributed in the six radial grooves, and also includes a push rod assembly located in the clamp housing to drive the three clamp arms and the three tool arms to open and close;

[0011] A guide sleeve is provided at one end of the clamp housing away from the fruit cluster placement device; the push rod assembly includes a first push rod slidably sleeved in the guide sleeve and six second push rods hinged to the first push rod, the six second push rods are all located in the clamp housing, three of the second push rods are hinged to one end of the three clamp arms, and the other three second push rods are hinged to one end of the three tool arms, and the first push rod passes through the guide sleeve and is connected to the first linear drive mechanism;

[0012] Each clamp arm moves radially open and close along with the movement of the second push rod and the first push rod. A flexible clip is provided at the front end of each clamp arm, and a pressure sensor is embedded on each flexible clip. The flexible clip includes an internal steel plate and a rubber layer sleeved on the outside of the steel plate.

[0013] Each tool support arm performs radial opening and closing movement along with the movement of the second push rod and the first push rod; a threshing blade or a kneading threshing block is installed at the front end of each tool support arm, and an adaptive arc section is provided at the front end of each threshing blade.

[0014] Specifically, the first push rod cooperates with the guide sleeve of the fixture housing and is connected to the second push rod. The first push rod passes through the guide sleeve and is connected to the return servo electric cylinder through the shaft sleeve, which is responsible for transmitting motion.

[0015] The threshing blade is mounted at the front end of the tool arm. After radial movement to the desired position, it then moves axially with the forward movement of the clamping threshing shell to thresh the corn ears. The blade tip is curved and available in multiple sizes, allowing for replacement based on the moisture content of the corn. The kneading threshing block, mounted at the front end of the tool arm, represents the second threshing solution of this invention. After radial movement with the tool arm to the desired position, it is driven by a servo motor to perform rotary kneading threshing.

[0016] As the clamp tightens on the corn ear, it monitors the force applied. A pressure sensor sends a signal to the control box, ensuring the clamp is tight and the corn kernels are intact. A flexible clamp, mounted at the front of the clamp's arm, moves radially to clamp the corn ear. Its core is made of 45-gauge steel and is covered in a thick, flexible rubber.

[0017] In one embodiment, the first linear drive mechanism includes a cylinder mounting plate mounted on the end of the box body and a three-axis guide rod cylinder mounted on the cylinder mounting plate, and the piston push rod of the three-axis guide rod cylinder is connected to the clamping threshing shell.

[0018] In one embodiment, the compound drive mechanism includes a horizontally fixed reciprocating servo electric cylinder, a sleeve connecting the output end of the reciprocating servo electric cylinder and the first push rod, a driven gear sleeved on the guide sleeve, a servo motor fixed to the bottom of the clamping threshing shell, a driving gear arranged at the output end of the servo motor and meshing with the driven gear, and a bearing seat arranged in the clamping threshing shell for supporting the guide sleeve.

[0019] In one embodiment, the corn ear placement device includes an corn ear placement platform hinged on the rear side wall of the upper cavity for placing corn ears, a gravity sensor arranged at the bottom below the corn ear placement platform, and an angle adjustment device for driving the angle adjustment of the corn ear placement platform.

[0020] In one embodiment, the fruit cluster placement platform is a secondary bending platform, which includes an integrally formed first bending part and a second bending part, the angle between the first bending part and the second bending part is 120°-150°, and the free end of the first bending part is hinged to the rear side wall of the upper cavity through a hinge.

[0021] Specifically, the corn ear placement platform is used to place corn ears, and the angle between the first bending part and the second bending part is 120°-150°, which can ensure that the corn ears are placed firmly.

[0022] In one embodiment, the angle adjustment device is an electric push rod, one end of which is hinged to the rear side wall of the upper cavity, and the other end of which is hinged to the connection between the first bending member and the second bending member.

[0023] Specifically, the electric push rod provides power for the rotation and retraction of the corn ear placement table; the gravity sensor detects whether the corn ears are placed and sends a signal to start the machine.

[0024] In one embodiment, the box body also includes a top plate with the feed port arranged on the top, a left plate and a right plate arranged on the left and right sides of the top plate, and a screen plate responsible for screening corn kernels and corn cobs is obliquely arranged in the lower cavity, the screen plate is an inclined plate with the right side higher and the left side lower, the right side of the screen plate is connected to the bottom of the middle part of the workbench, the left side of the screen plate is connected to the left side wall of the lower cavity, the core outlet is located at the connection between the left side of the screen plate and the left side wall of the lower cavity, a mesh area is provided on the right side of the screen plate, and a grain guide plate is obliquely arranged at the bottom of the mesh area, the grain guide plate is an inclined plate with the right side lower and the left side higher, the left side of the grain guide plate is connected to the bottom edge of the mesh area, the right side of the grain guide plate is connected to the right side wall of the lower cavity, and the discharge port is located at the connection between the right side of the screen plate and the right side wall of the lower cavity.

[0025] In one embodiment, an operation control box responsible for controlling the entire machine is further included and located at the bottom of the lower cavity.

[0026] The workflow is as follows:

[0027] Operating Mode 1: When a corn ear is placed on the corn cob placement table, a gravity sensor senses the change in mass and sends a signal to the control box. A binocular camera captures images of the corn cob at both ends and transmits this information to the control box, which determines the physical characteristics of the corn cob. The clamping and threshing device on one side of the machine, driven by a three-axis guide cylinder, advances to the appropriate position. Based on the corn cob information, the reciprocating servo electric cylinder in the clamping and threshing device advances. This motion is transmitted through the first and second push rods in the clamping and threshing module, causing the clamp arms to radially retract and clamp the corn cob. The corn cob placement table is then retracted to its vertical position by the electric push rods. On the other side of the machine, the clamping threshing unit, controlled by the control box, advances a reciprocating servo electric cylinder. This motion is transmitted through the first and second push rods in the clamping threshing module, causing the tool arm to move radially. After the threshing blades have moved radially to the desired position (where the cob connects to the kernels), a three-axis guide cylinder advances the clamping threshing shell. The threshing blades thresh the corresponding row of corn cobs. After one feed is complete, the three-axis guide cylinder retracts the clamping threshing shell. The clamping threshing module, driven by the servo motor, rotates a certain angle and continues to thresh the remaining rows of corn cobs. This completes the threshing of half the kernels from the cob. Next, the reciprocating servo electric cylinder in the clamping threshing unit advances, transmitting this motion through the first and second push rods in the clamping threshing module, causing the clamp arm to radially retract and clamp the corn cob. The same process is then used to thresh the kernels from the other half of the cob. After threshing, the corn cobs are transported out of the machine by gravity through the screen. The removed corn kernels fall naturally under the action of gravity, pass through the sieve holes above the screen plate under the action of gravity and cross-flow fans, and are gathered by the kernel guide plates and transported out of the box for collection.

[0028] Mode 2: When a corn ear is placed on the corn cob placement platform, a gravity sensor senses the change in mass and sends a signal to the control box. A binocular camera captures images of the corn cob at both ends and transmits this information to the control box, which determines the physical characteristics of the corn cob. The clamping and threshing device on one side of the machine, driven by a three-axis guide cylinder, advances to the appropriate position. Based on the corn cob information, the reciprocating servo electric cylinder in the clamping and threshing device advances. This motion is transmitted through the first and second push rods in the clamping and threshing module, causing the clamp arms to radially retract and clamp the corn cob. The corn cob placement platform is then retracted to its vertical position by the electric push rods. The clamping threshing device on the other side of the machine is controlled by the control box. The reciprocating servo electric cylinder advances, and the motion is transmitted through the first and second push rods in the clamping threshing module, causing the tool arm to move radially. After the threshing block moves radially to the appropriate position (the position where initial pressure is applied to the corn kernels), the clamping threshing module rotates under the drive of the servo motor to thresh. The three-axis guide rod cylinder pushes the clamping threshing shell from the end of the corn cob to the middle and continuously feeds it. After half of the kernels in the corn cob are threshed, the three-axis guide rod cylinder retracts the clamping threshing shell. After that, the reciprocating servo electric cylinder in the clamping threshing device advances, and the motion is transmitted through the first and second push rods in the clamping threshing module, causing the clamp arm to radially contract and clamp the corn cob shaft. The same method is used to thresh the kernels in the other half of the corn cob. After threshing is completed, the corn cob shaft is transported out of the machine through the screen plate under the action of gravity. The removed corn kernels fall naturally under the action of gravity, pass through the sieve holes above the screen plate under the action of gravity and cross-flow fans, and are gathered by the kernel guide plates and transported out of the box for collection.

[0029] The beneficial effects of the present invention are as follows:

[0030] The present invention proposes a bidirectional clamping and feeding type corn single ear thresher. This technology uses a clamp to adaptively clamp the corn ears and uses an adaptive tool to perform feeding or rotary kneading threshing. It can solve the problem of low threshing rate caused by the different sizes and shapes of corn parent ears. There is no need to manually adjust the threshing chamber for different corn varieties, which improves work efficiency. And different types of tools can be replaced according to the moisture content of the corn kernels, or rotary kneading threshing can be selected to reduce the kernel damage rate. This technology significantly improves the threshing efficiency and threshing rate of corn breeding, reduces the kernel damage rate, has important application value, and can effectively promote the further development of the corn breeding industry.

[0100] In one embodiment, the box body 3 also includes a top plate 301 with the feed port set on the top, a left plate 305 and a right plate 306 set on the left and right sides of the top plate 301, and a screen plate 303 responsible for screening corn kernels and corn cobs is tilted in the lower cavity.

[0101] In one embodiment, an operation control box 307 is further included, which is located at the bottom of the lower cavity and is responsible for controlling the entire machine.

[0102] The workflow is as follows:

[0103] Mode 1: When a corn cob is placed on the corn cob placement platform 201, the gravity sensor 202 senses the change in mass and sends a signal to the control box 307. The binocular camera 108 captures images of the corn cobs at both ends and transmits this information to the control box 307. This information is then determined by the physical properties of the corn cobs. The clamping and threshing device 1 on one side of the machine is then advanced to the appropriate position by the three-axis guide cylinder 101. Based on the corn cob information, the reciprocating servo electric cylinder 103 in the clamping and threshing device 1 advances. This motion is transmitted through the first and second push rods 109.2 in the clamping and threshing module 109, causing the clamp arm 109.3 to radially contract and clamp the corn cob. The corn cob placement platform 201 is then retracted to its vertical position by the electric push rod 204. The clamping threshing device 1 on the other side of the machine is controlled by the control box 307. The return servo electric cylinder 103 feeds, and the movement is transmitted through the first push rod 109.8 and the second push rod 109.2 in the clamping threshing module 109, causing the tool support arm 109.4 to move radially. After the threshing blade 109.7 moves radially to the appropriate position (the connection between the core shaft and the grain), the three-axis guide rod cylinder 101 pushes the clamping threshing shell 111 to feed, and the threshing blade 109.7 thres the corresponding row of corn ears. After one feeding is completed, the three-axis guide rod cylinder 101 retracts the clamping threshing shell 111, and the clamping threshing module 109 rotates a certain angle under the drive of the servo motor 105, and continues to feed to thresh the remaining rows of corn ears. At this point, half of the kernels in the corn ear are completely threshed. Next, the reciprocating servo electric cylinder 103 in the clamping and threshing device 1 advances, and this motion is transmitted through the first push rod 109.8 and second push rod 109.2 in the clamping and threshing module 109, causing the clamp arm 109.3 to radially contract and clamp the corn cob. The remaining kernels from the corn cob are threshed in the same manner as described above. After threshing is complete, the corn cob is transported out of the machine through the screen plate 303 under the influence of gravity. The removed kernels naturally fall under the influence of gravity and the crossflow fan 304, passing through the sieve holes above the screen plate 303. They are then gathered by the kernel guide plate 308 and transported out of the box 3 for collection.

[0104] Mode 2: When a corn cob is placed on the corn cob placement platform 201, the gravity sensor 202 senses the change in mass and sends a signal to the control box 307. The binocular camera 108 captures images of the corn cob at both ends and transmits this information to the control box 307. This information is then determined by the physical properties of the corn cob. The clamping and threshing device 1 on one side of the machine is then advanced to the appropriate position by the three-axis guide cylinder 101. Based on the corn cob information, the reciprocating servo electric cylinder 103 in the clamping and threshing device 1 advances. This motion is transmitted through the first and second push rods 109.2 in the clamping and threshing module 109, causing the clamp arm 109.3 to radially contract and clamp the corn cob. The corn cob placement platform 201 is then retracted to its vertical position by the electric push rod 204. The clamping threshing device 1 on the other side of the machine is controlled by the control box 307, and the return servo electric cylinder 103 feeds. The movement is transmitted through the first push rod 109.8 and the second push rod 109.2 in the clamping threshing module 109 to make the tool support arm 109.4 move radially. After the rubbing threshing block 109.9 moves radially to the appropriate position (the position when the initial pressure is formed on the corn kernels), the clamping threshing module 109 rotates and threshes under the drive of the servo motor 105. The three-axis guide rod cylinder 101 pushes the clamping threshing shell 111 to continuously feed from the end of the corn cob to the middle until half of the kernels of the corn cob are threshed. The three-axis guide rod cylinder 101 retracts the clamping threshing shell 111. Next, the reciprocating servo electric cylinder 103 in the clamping and threshing device 1 advances, and this motion is transmitted through the first push rod 109.8 and second push rod 109.2 in the clamping and threshing module 109, causing the clamp arm 109.3 to radially contract and clamp the corn cob. The remaining kernels from the corn cob are threshed in the same manner as described above. After threshing is complete, the corn cob is transported out of the machine through the screen plate 303 under the influence of gravity. The removed kernels naturally fall under the influence of gravity and the crossflow fan 304, passing through the sieve holes above the screen plate 303. They are then gathered by the kernel guide plate 308 and transported out of the box 3 for collection.
