Peanut harvesting is mainly done in two stages: first, peanut threshing machines are used to pull the peanuts from the ground, and they are dried for two to three days. Then, peanut pick-up harvesters are used to pick up, remove, and clean the peanuts. When the peanut pick-up harvester is in operation, the picking platform is prone to blockage, which reduces harvesting efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a harvester anti-clogging device and a harvester, which addresses the shortcomings of the existing technology.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A harvester anti-blocking device includes: a frame, an auger, an auger shaft, and a pick-up table reversing device. The auger shaft is rotatably mounted on the frame, the auger is mounted on the auger shaft, a cutter intermediate shaft is rotatably mounted on the frame, and the pick-up table reversing device is mounted on the cutter intermediate shaft. The auger shaft and the pick-up table reversing device are connected in a transmission connection.

[0005] The beneficial effects of adopting the technical solution of this utility model are: when the auger gets clogged, the auger shaft is reversed by the pick-up table reversing device, thereby reversing the auger and spitting out the blockage, solving the problem of pick-up table blockage and improving work efficiency.

[0006] Furthermore, the picking table reversing device includes: a forward rotating wheel, a reversing device, and a reverse rotating wheel. The forward rotating wheel and the reverse rotating wheel are both rotatably mounted on the intermediate shaft of the cutting table via bearings. The reversing device can slide along the axial direction of the intermediate shaft of the cutting table and is drively connected to the intermediate shaft of the cutting table. The reversing device is located between the forward rotating wheel and the reverse rotating wheel. The side of the forward rotating wheel near the reversing device, both sides of the reversing device, and the side of the reverse rotating wheel near the reversing device are all equipped with transmission teeth.

[0007] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the forward and reverse rotating wheels are connected to the intermediate shaft of the cutter head via bearings; the reversing device is connected to the intermediate shaft of the cutter head via a key and can slide left and right on the intermediate shaft. When the reversing device is connected to the forward rotating wheel via a jaw clutch structure, the forward rotation transmission system operates, and the auger rotates forward. When the reversing device is connected to the reverse rotating wheel via a jaw clutch structure, the reverse rotation transmission system operates, and the auger rotates in reverse.

[0008] Furthermore, the reversing device is a ring structure, and the inner ring of the reversing device is provided with a first sliding tooth parallel to the axis of the intermediate shaft of the cutting table. The intermediate shaft of the cutting table is provided with a second sliding tooth adapted to the first sliding tooth, and the first sliding tooth meshes with the second sliding tooth.

[0009] The beneficial effect of adopting the above-mentioned further technical solution is that the reversing device is connected to the intermediate shaft of the cutter table via a key and can slide left and right on the intermediate shaft. This facilitates sliding the reversing device as needed to achieve engagement between the reversing device and the forward or reverse rotating wheel, thereby realizing forward and reverse rotation.

[0010] Furthermore, the outer ring of the reversing device is connected to a housing via a bearing, and the housing is connected to a pair of slide rods, which are slidably mounted on the frame.

[0011] The beneficial effects of adopting the above-mentioned further technical solution are: the setting of a pair of sliding rods facilitates the smooth sliding of the reversing device along the axial direction of the cutter table's central axis, thereby improving stability and reliability.

[0012] Furthermore, a pair of slide rods are connected to a reversing support plate, the reversing support plate is connected to a push rod, a spring is respectively sleeved on the pair of slide rods, a support plate is installed on the frame, the pair of slide rods are slidably installed on the support plate, the support plate is located between the reversing support plate and the forward rotating wheel, and the spring abuts against the support plate.

[0013] The beneficial effects of adopting the above-mentioned further technical solution are as follows: When the auger becomes clogged, the peanut machine's picking table reversing device is pushed by a push rod to change direction by reversing the reversing plate. The forward rotating wheel disengages from the reversing device, and the forward rotation is disengaged. The reversing device continues to engage with the reverse rotating wheel, engaging in reverse rotation. Through the transmission structure, it drives the auger shaft and the auger to rotate in the opposite direction, expelling the blockage and resolving the picking table clogging problem. After resolving the picking table clogging problem, the push rod reverses direction, and under the action of the spring, it disengages from the forward rotation engagement, driving the auger shaft to start normal harvesting operations through the transmission structure.

[0014] Furthermore, both the forward-rotating wheel and the reverse-rotating wheel are sprockets. A first input wheel and a second input wheel are fixedly mounted on the auger shaft. Both the first input wheel and the second input wheel are sprockets. The forward-rotating wheel is connected to the first input wheel via a first chain, and the reverse-rotating wheel is connected to the second input wheel via a second chain.

[0015] The beneficial effects of adopting the above-mentioned further technical solution are: the transmission is achieved through sprockets and chains, which facilitates the synchronous rotation of each shaft, reduces transmission loss, and improves stability and reliability.

[0016] Furthermore, a pair of reversing auxiliary wheels are installed on the frame, the second input wheel is located between the pair of reversing auxiliary wheels, the second chain is respectively sleeved on the reverse wheel and the pair of reversing auxiliary wheels, and the second input wheel meshes with the outer side of the second chain; the first chain is respectively sleeved on the forward wheel and the first input wheel.

[0017] The beneficial effects of adopting the above-mentioned further technical solution are: the setting of a pair of reversing auxiliary wheels is used to realize the reversal of the second input wheel, the structure is simple, and it is easy to install and maintain.

[0018] Furthermore, a pickup is rotatably mounted on the frame, and a one-way clutch is mounted on the pickup. The auger shaft is connected to the one-way clutch for transmission.

[0019] The beneficial effects of adopting the above-mentioned further technical solution are: during forward rotation, the one-way clutch transmits power, driving the pickup to rotate forward. During reverse rotation, the one-way clutch cuts off the power, preventing the pickup from jamming.

[0020] Furthermore, the one-way clutch includes: an outer ring, multiple tongue pins, and an inner ring. The outer ring is rotatably sleeved on the outside of the inner ring. The multiple tongue pins are hinged to the outer wall of the inner ring. The outer ring is provided with one-way slots that are adapted to the multiple tongue pins. A third input wheel is mounted on the outer ring, and an output wheel is mounted on the auger shaft. Both the third input wheel and the output wheel are sprockets. The third input wheel and the output wheel are connected by a third chain drive. The inner ring is connected to the pickup.

[0021] The beneficial effects of adopting the above-mentioned further technical solution are as follows: When the pickup rotates forward, it works normally. The outer ring pushes the tongue pin, which drives the inner ring to rotate. The inner ring is connected to the pickup, causing the pickup to rotate forward. When rotating in reverse, the outer ring rotates in the opposite direction, the tongue pin cannot transmit power, and the one-way clutch cuts off the power, preventing the pickup from jamming.

[0038] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0043] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] like Figures 1 to 11 This utility model provides a harvester anti-clogging device, including: a frame, an auger 2, an auger shaft 5, and a pickup table reversing device 7. The auger shaft 5 is rotatably mounted on the frame, the auger 2 is mounted on the auger shaft 5, a cutting table intermediate shaft 13 is rotatably mounted on the frame, and the pickup table reversing device 7 is mounted on the cutting table intermediate shaft 13. The auger shaft 5 and the pickup table reversing device 7 are connected in a transmission manner.

[0045] The beneficial effects of adopting the technical solution of this utility model are: when the auger gets clogged, the auger shaft is reversed by the pick-up table reversing device, thereby reversing the auger and spitting out the blockage, solving the problem of pick-up table blockage and improving work efficiency.

[0046] The pickup platform may include: pickup device 1, auger 2, and bridge 3.

[0047] This utility model primarily addresses the problem of excessive peanut vine and pod feeding during peanut harvesting, leading to blockage of the picking platform and requiring the operator to dismount and clear the blockage, thus reducing work efficiency. It provides a method where the operator can reverse the picking platform from inside the cab, resolving the blockage issue.

[0048] During peanut harvesting, the picker 1 lifts the peanut vines and transports them backward to the auger (auger 2) on the picking platform. Auger 2 then transports the peanut vines from both sides towards the middle to the feeding inlet of bridge 3. If the peanut vines are wet and the feeding volume is too large, the auger (auger 2) may become clogged. In this case, the peanut harvester's picking platform reversing device (picking platform reversing device 7) is activated by push rod 6, disengaging the forward rotation from the reverse rotation. The transmission structure then drives auger 2 to rotate in the opposite direction, expelling the blockage. After resolving the blockage, push rod 6 reverses the rotation, disengaging the reverse rotation from the forward rotation, and normal harvesting begins. Picker 1 operates normally during forward rotation; during reverse rotation, one-way clutch 4 cuts off power to prevent picker 1 from jamming. The picking platform reversing device 7 is activated by the operating device to reverse the rotation, improving work efficiency.

[0049] like Figures 1 to 11Furthermore, the picking table reversing device 7 includes: a forward rotating wheel 9, a reversing device 10, and a reverse rotating wheel 11. The forward rotating wheel 9 and the reverse rotating wheel 11 are rotatably mounted on the intermediate shaft 13 of the cutting table via bearings. The reversing device 10 can slide along the axial direction of the intermediate shaft 13 of the cutting table and is connected to the intermediate shaft 13 of the cutting table in a transmission connection. The reversing device 10 is located between the forward rotating wheel 9 and the reverse rotating wheel 11. The side of the forward rotating wheel 9 near the reversing device 10, both sides of the reversing device 10, and the side of the reverse rotating wheel 11 near the reversing device 10 are all equipped with transmission teeth.

[0050] The beneficial effects of adopting the above-mentioned further technical solution are as follows: the forward and reverse rotating wheels are connected to the intermediate shaft of the cutter head via bearings; the reversing device is connected to the intermediate shaft of the cutter head via a key and can slide left and right on the intermediate shaft. When the reversing device is connected to the forward rotating wheel via a jaw clutch structure, the forward rotation transmission system operates, and the auger rotates forward. When the reversing device is connected to the reverse rotating wheel via a jaw clutch structure, the reverse rotation transmission system operates, and the auger rotates in reverse.

[0051] like Figures 1 to 11 Furthermore, the reversing device 10 is a ring structure, and the inner ring of the reversing device 10 is provided with a first sliding tooth parallel to the axis of the intermediate shaft 13 of the cutting table. The intermediate shaft 13 of the cutting table is provided with a second sliding tooth adapted to the first sliding tooth, and the first sliding tooth meshes with the second sliding tooth.

[0052] The beneficial effect of adopting the above-mentioned further technical solution is that the reversing device is connected to the intermediate shaft of the cutter table via a key and can slide left and right on the intermediate shaft. This facilitates sliding the reversing device as needed to achieve engagement between the reversing device and the forward or reverse rotating wheel, thereby realizing forward and reverse rotation.

[0053] like Figures 1 to 11 Furthermore, the outer ring of the reversing device 10 is connected to a housing 15 via a bearing, and the housing 15 is connected to a pair of slide rods 17, which are slidably mounted on the frame.

[0054] The beneficial effects of adopting the above-mentioned further technical solution are: the setting of a pair of sliding rods facilitates the smooth sliding of the reversing device along the axial direction of the cutter table's central axis, thereby improving stability and reliability.

[0055] like Figures 1 to 11 Furthermore, a pair of slide rods 17 are connected to a reversing support plate 8, the reversing support plate 8 is connected to a push rod 6, a spring 18 is respectively sleeved on the pair of slide rods 17, a support plate 26 is installed on the frame, the pair of slide rods 17 are slidably installed on the support plate 26, the support plate 26 is located between the reversing support plate 8 and the forward rotating wheel 9, and the spring 18 abuts against the support plate 26.

[0056] The beneficial effects of adopting the above-mentioned further technical solution are as follows: When the auger becomes clogged, the peanut machine's picking table reversing device is pushed by a push rod to change direction by reversing the reversing plate. The forward rotating wheel disengages from the reversing device, and the forward rotation is disengaged. The reversing device continues to engage with the reverse rotating wheel, engaging in reverse rotation. Through the transmission structure, it drives the auger shaft and the auger to rotate in the opposite direction, expelling the blockage and resolving the picking table clogging problem. After resolving the picking table clogging problem, the push rod reverses direction, and under the action of the spring, it disengages from the forward rotation engagement, driving the auger shaft to start normal harvesting operations through the transmission structure.

[0057] The spring 18 can be a compression spring, which is used to keep the reversing device 10 and the forward rotating wheel 9 always engaged. The user can connect the push rod 16 to the interior of the cab via a transmission mechanism or leave it exposed on the outside, depending on actual needs.

[0058] like Figures 1 to 11 Furthermore, both the forward rotating wheel 9 and the reverse rotating wheel 11 are sprockets. The auger shaft 5 is fixedly mounted with a first input wheel 19 and a second input wheel 20. Both the first input wheel 19 and the second input wheel 20 are sprockets. The forward rotating wheel 9 is connected to the first input wheel 19 via a first chain 21, and the reverse rotating wheel 11 is connected to the second input wheel 20 via a second chain 22.

[0059] The beneficial effects of adopting the above-mentioned further technical solution are: the transmission is achieved through sprockets and chains, which facilitates the synchronous rotation of each shaft, reduces transmission loss, and improves stability and reliability.

[0060] like Figures 1 to 11 Furthermore, a pair of reversing auxiliary wheels 23 are installed on the frame, the second input wheel 20 is located between the pair of reversing auxiliary wheels 23, the second chain 22 is respectively sleeved on the reversing wheel 11 and the pair of reversing auxiliary wheels 23, the second input wheel 20 meshes with the outer side of the second chain 22; the first chain 21 is respectively sleeved on the forward rotating wheel 9 and the first input wheel 19.

[0061] The beneficial effects of adopting the above-mentioned further technical solution are: the setting of a pair of reversing auxiliary wheels is used to realize the reversal of the second input wheel, the structure is simple, and it is easy to install and maintain.

[0062] Among them, the reversing auxiliary wheel can be a sprocket.

[0063] like Figures 1 to 11 Furthermore, a pickup 1 is rotatably mounted on the frame, and a one-way clutch 4 is mounted on the pickup 1. The auger shaft 5 is connected to the one-way clutch 4 in a transmission connection.

[0064] The beneficial effects of adopting the above-mentioned further technical solution are: during forward rotation, the one-way clutch transmits power, driving the pickup to rotate forward. During reverse rotation, the one-way clutch cuts off the power, preventing the pickup from jamming.

[0065] like Figures 1 to 11 Furthermore, the one-way clutch 4 includes: an outer ring 12, a plurality of tongue pins 14, and an inner ring 16. The outer ring 12 is rotatably sleeved on the outside of the inner ring 16. The plurality of tongue pins 14 are hinged to the outer wall of the inner ring 16. The outer ring 12 is provided with one-way slots that are adapted to the plurality of tongue pins 14. A third input wheel 24 is mounted on the outer ring 12, and an output wheel is mounted on the auger shaft 5. Both the third input wheel 24 and the output wheel are sprockets. The third input wheel 24 and the output wheel are connected by a third chain 25. The inner ring 16 is connected to the pickup 1.

[0066] The beneficial effects of adopting the above-mentioned further technical solution are as follows: When the pickup rotates forward, it works normally. The outer ring pushes the tongue pin, which drives the inner ring to rotate. The inner ring is connected to the pickup, causing the pickup to rotate forward. When rotating in reverse, the outer ring rotates in the opposite direction, the tongue pin cannot transmit power, and the one-way clutch cuts off the power, preventing the pickup from jamming.

[0067] The output wheel can be located between the first input wheel 19 and the second input wheel 20. The surfaces of the tongue pin 14 and the one-way slot can both have a rounded transition structure. The inner ring 12 can be rotatably fitted onto the outside of the inner ring 16 via a bearing. The principle of the one-way clutch 4 is similar to that of a bicycle hub.

[0068] like Figures 1 to 11 When the peanut harvester is operating, the picker 1 picks up the peanut vines and transports them backward to the pick-up platform to feed the auger (auger 2). Auger 2 transports the peanut vines on both sides to the middle to the feeding inlet of the bridge 3. During this process, if the peanut vines are wet and the feeding amount is too large, the feeding auger (auger 2) will become blocked. The peanut harvester's pick-up platform reversing device 7 is pushed by the push rod 6 to reverse the direction of the reversing support plate 8. The forward rotation wheel 9 is disengaged from the reversing device 10, and the forward rotation is disengaged. The reversing device 10 continues to engage with the reverse rotation wheel 11, and the reverse rotation is engaged. Through the transmission structure, the auger shaft 5 and the auger 2 are driven to rotate in the opposite direction, expelling the blockage. After the pick-up platform blockage problem is resolved, the push rod 6 is reversed and disengaged from the forward rotation under the action of the spring 18. Through the transmission structure, the auger shaft 5 is driven to start normal harvesting operation. When the pickup 1 rotates forward, it works normally. The outer ring 12 pushes the tongue pin 14, and the tongue pin 14 drives the inner ring 16 to rotate. The inner ring 16 is connected to the pickup 1 and drives the pickup 1 to rotate forward. When it rotates in reverse, the outer ring 12 rotates in the opposite direction, and the tongue pin 14 cannot transmit power. The one-way clutch 4 cuts off the power to prevent the pickup 1 from getting stuck.

[0069] The forward and reverse rotation systems are two separate transmission systems. The forward rotating wheel 9 and the reverse rotating wheel 11 are connected to the intermediate shaft 13 of the cutter table via bearings. The reversing device 10 is connected to the intermediate shaft 13 of the cutter table via a key and can slide left and right on the intermediate shaft 13 of the cutter table. When the reversing device 10 is connected to the forward rotating wheel 9 via a jaw clutch structure, the forward rotation transmission system is working and the auger (auger 2) is fed in and rotates in the forward direction. When the reversing device 10 is connected to the reverse rotating wheel 11 via a jaw clutch structure, the reverse rotation transmission system is working and the auger (auger 2) is fed in and rotates in the reverse direction.

[0072] The beneficial effects of adopting the technical solution of this utility model are: when the auger gets clogged, the auger shaft is reversed by the pick-up table reversing device, thereby reversing the auger and spitting out the blockage, solving the problem of pick-up table blockage and improving work efficiency.
