Description

Technical Field

[0001] This invention relates to the field of soybean and corn harvesting technology, specifically a harvesting device for soybean and corn strip intercropping. Background Technology

[0002] A patent application (CN118340024A) for a harvesting device for soybean and corn strip planting includes a drive frame, a swing adjustment cylinder, a harvester frame, a conveyor, a collection bin, a double-sliding mechanism, and a harvesting system. Its advantages are: by using two adjustment cylinders for the stroke and return strokes respectively, the harvester frame, conveyor, collection bin, double-sliding mechanism, and harvesting system as a whole can be tilted along the hinge point between the harvester frame and the extension end of the drive frame. This design changes the horizontal linear distance between the two harvesting systems, allowing them to adapt to the varying spacing between soybeans and corn in a soybean-corn strip planting area. Compared to conventional harvesting devices, this operation effectively achieves a simple structure, low cost, and rich functionality.

[0003] In the prior art, including the aforementioned patents, existing harvesting devices, when harvesting soybeans and corn, are prone to swaying from side to side when moving in the field due to the uneven terrain of farmland, which differs from flat roads. Furthermore, during the growth of soybeans and corn, their roots and stems maintain a vertically upward growth posture, causing the harvesting blades to deviate from the preset cutting trajectory due to the swaying of the device. On the one hand, the swaying harvesting blades may frequently touch the field, causing accelerated wear and even damage to the blades; on the other hand, the blades may accidentally touch the stalks or ears of soybeans or corn, damaging the crop and not only reducing harvesting quality but also causing yield loss. Summary of the Invention

[0004] The problem this invention aims to solve is: when the harvesting device moves left and right in the field and sways, the harvesting blades can still maintain a parallel state with the soybean or corn roots and stalks for harvesting.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a harvesting device for soybean-corn strip intercropping, comprising a harvester body, a harvesting device mounted on the harvester body, a lifting mechanism for adjusting the height of the harvesting device mounted on the harvester body, an adjustment component for monitoring the relative tilt of the harvester body mounted on the lifting mechanism, a balancing component for adjusting the harvesting device to maintain a relatively parallel state when cutting crop roots and stems, and a linkage component for driving the balancing components on both sides to move synchronously.

[0006] Preferably, the lifting mechanism includes a support plate, on which a lifting plate and a lifting assembly for driving the lifting plate to move up and down are provided. The lifting plate is provided with a first supporting rotating block, and the first supporting rotating block has a first fixing groove arranged in a circumferential array.

[0007] Preferably, the adjustment assembly includes a support housing, one side of which is rotatably connected to a first support rotating block. A first electric insertion rod is provided on the same side of the support housing, one end of which is inserted into a first fixed groove. The harvesting device is located on the side of the support housing away from the lifting mechanism.

[0008] Preferably, the adjustment assembly further includes a support rod disposed inside the support housing, an adjustment counterweight is disposed at the lower end of the support rod, and an electronic control button is disposed inside the support housing, with the support rod and the electronic control button being abutted together.

[0009] Preferably, the support housing is provided with a second support rotating block, and the second support rotating block has a second fixing groove arranged in a circumferential array.

[0010] Preferably, the balancing assembly includes a balancing housing, which is rotatably connected to a second support block. A second electric insertion rod is provided on the balancing housing and is inserted into a second fixed groove.

[0011] Preferably, the balancing assembly further includes a balancing motor, which is mounted on the balancing housing. The output end of the balancing motor is provided with a rotating rod, which is rotatably connected to the balancing housing. A take-up roller is provided on the rotating rod, and a traction rope is wound on the take-up roller.

[0012] Preferably, the balancing shell is provided with a movable roller, the movable roller is provided with a balancing counterweight, the balancing counterweight is provided with a connecting rod, and the end of the connecting rod away from the movable roller is connected to the traction rope.

[0013] Preferably, the linkage component includes a linkage rod, which is disposed on the balance housing. Linkage plates are provided at both ends of the linkage rod, and the linkage plates are in contact with the balance counterweight. A connecting collar is provided on the linkage plate, and the connecting collar is sleeved on the balance counterweight.

[0014] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0015] (1) The adjustment component detects the entire harvester body. When the harvester body tilts, the adjustment component is triggered. The adjustment component unlocks the lock between itself and the harvester body. Then, the center of gravity of the tilted adjustment component is adjusted by the balance component, so that the entire adjustment component is adjusted to a vertical state. The adjustment component adjusts the harvesting equipment to be parallel to the field, so that the harvesting equipment is harvested vertically when harvesting the roots and stems of crops, reducing the possibility of the harvesting equipment touching the field and soybean or corn products, and preventing damage to the harvesting equipment or soybean or corn products.

[0016] (2) When harvesting on different fields, the electric control button can be switched from controlling the first electric rod to the second electric rod. At this time, the harvester body is moved to the inclined field. The tilt of the body triggers the adjustment component. At this time, the adjustment component drives the second electric rod to unlock. The support shell and the lifting plate are still locked. At this time, the adjustment component and the balance component adjust the angle of the balance shell and adjust the balance shell to the vertical state. The balance shell and the support shell are locked. Then the electric control button is switched to controlling the first electric rod. At this time, the whole body and the harvesting equipment are in an inclined state. The balance component used to adjust the harvesting equipment is in a balanced state. When the harvester body is harvesting crops on the inclined field, the tilt of the body is used as the reference. The angle of the harvesting equipment is adjusted when there is shaking. In this way, the harvesting equipment can cut the inclined roots and stems on the inclined field in a vertical state. This way, even on the inclined field, the harvesting equipment can still harvest in a state parallel to the inclined field. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0035] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "comprising" or "including," and similar terms used in this disclosure, mean that an element or object preceding the term encompasses the elements or objects listed following the term and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but may also include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0036] like Figures 1 to 11 As shown, the present invention provides a harvesting device for soybean-corn strip intercropping, including a harvester body 1, a harvesting device 3 mounted on the harvester body 1, a lifting mechanism 2 for adjusting the height of the harvesting device 3 mounted on the harvester body 1, an adjustment component 4 for monitoring the relative tilt of the harvester body 2, a balancing component 5 for adjusting the harvesting device 3 to maintain a relatively parallel state with the cutting of crop roots and stems, and a linkage component 6 for driving the two balancing components 5 to move synchronously.

[0037] The working principle and usage process of this invention: The harvester body 1 harvests soybeans and corn in a strip-planted field. The lifting mechanism 2 adjusts the height of the harvesting device 3 according to whether soybeans or corn are being harvested. Then, the harvester body 1 moves forward, and the harvesting device 3 harvests either soybeans or corn. However, due to the uneven surface of the field, the harvester body 1 sways left and right during the forward movement, and the harvester body 1 also causes the harvesting device 3 to tilt. At this time, the adjustment component 4 monitors the tilt state of the vehicle body. When the vehicle body tilts, the adjustment component 4 is triggered, driving the balancing component 5 to work. The linkage component 6 keeps the balancing components 5 on both sides working synchronously. The balancing component 5 adjusts the height of the harvester body 1 according to the height of the field. The harvesting device 3 is tilted to adjust its position. The harvesting device 3 will rotate in the opposite direction according to the tilt of the harvester body 1 until it returns to its initial position (the initial position is the position where the harvesting device 3 is initially set to be parallel to the ground. If the field is level, the harvesting device 3 will return to the level position. If the field is tilted, the harvesting device 3 will return to the initial tilt position when the soybeans or corn roots are cut). This ensures that the harvesting device 3 will not touch the field when harvesting soybeans or corn, or touch soybeans or corn as the machine body tilts, causing damage to soybeans or corn. It keeps the harvesting device 3 parallel to the soybean roots when cutting.

[0038] Please refer to Figure 2 and Figure 10 The lifting mechanism 2 includes a support plate 21, a lifting plate 22 and a lifting assembly for driving the lifting plate 22 to move up and down. The lifting plate 22 is provided with a first support rotating block 23, and the first support rotating block 23 is provided with a first fixing groove 24 in a circular array.

[0039] The lifting assembly includes a lifting motor, a threaded rod, and a slide rail mounted on the support plate 21. The lifting plate 22 is threaded onto the threaded rod. By driving the lifting motor, the lifting motor drives the threaded rod to rotate, which in turn drives the lifting plate 22 to move up and down in coordination with the slide rail. The lifting plate 22 drives the first support rotating block 23 to move up and down, thereby driving the adjustment assembly 4 and the harvesting equipment 3 to move up and down.

[0040] Please refer to Figures 4-8 The adjustment component 4 includes a support housing 41, one side of which is rotatably connected to the first support rotating block 23. A first electric insertion rod 42 is provided on the same side of the support housing 41, one end of which is inserted into the first fixed groove 24. The harvesting device 3 is located on the side of the support housing 41 away from the lifting mechanism 2. The adjustment component 4 also includes a support rod 43, which is located inside the support housing 41. An adjustment counterweight 44 is provided at the lower end of the support rod 43. An electric control button 45 is provided inside the support housing 41, and the support rod 43 is in contact with the electric control button 45.

[0041] The support housing 41 is rotatably connected to the first support rotating block 23 via a rotating shaft. In the initial state, the first electric insert rods 42 on both sides extend and insert into the first fixed slots 24, locking the lifting plate 22 and the support housing 41 together. When the harvester body 1 moves in the field and tilts, the support housing 41 will also tilt. However, the adjusting counterweight 44 will maintain a vertical downward force. At this time, there is a relative displacement between the adjusting counterweight 44, the support rod 43, and the support housing 41 (the support rod 43 is hinged inside the support housing 41. When the adjusting counterweight 44 and the support housing 41 have a relative displacement, the gravity of the adjusting counterweight 44 pulls the hinge point of the support rod 43 to rotate relative to the support housing 41). At this time, the support rod 43 is no longer in a vertical state, and the support rod on one side... Pressing the electronic control button 45 causes button 43 to transmit an electrical signal to the first electric insert rod 42 and the balancing assembly 5, driving them to extend from the first fixed slot 24. The balancing assembly 5 adjusts the balance points on both sides of the fixed housing, causing it to move towards a state parallel to the road surface. When the fixed housing returns to a parallel state, the support rod 43 is perpendicular to the fixed housing, and button 45 is no longer pressed. The balancing assembly 5 then stops working, and the first electric insert rod 42 extends back into the first fixed slot 24 to lock the support housing 41 and the lifting plate 22. Button 45 will only trigger a signal when the support rod 43 deflects at an angle exceeding 3° due to vehicle tilt.

[0042] Please refer to Figures 4-11 The supporting housing 41 has a second supporting rotating block 46 inside, and the second supporting rotating block 46 has a second fixing groove 47 arranged in a circular array. The balancing assembly 5 includes a balancing housing 51, which is rotatably connected to the second supporting rotating block 46. The balancing housing 51 is provided with a second electric insertion rod 59, which is inserted into the second fixing groove 47. The balancing assembly 5 also includes a balancing motor 53, which is mounted on the balancing housing 51. The output end of the balancing motor 53 is provided with a rotating rod 54, which is rotatably connected to the balancing housing 51. The system includes a take-up roller 55 with a traction rope 56 wound on it, a moving roller 52 on the balance housing 51, a counterweight 58 on the moving roller 52, a connecting rod 57 on the counterweight 58, and a connecting rod 57 at the end of the connecting rod 57 away from the moving roller 52 connected to the traction rope 56. The linkage assembly 6 includes a linkage rod 61 on the balance housing 51, with linkage plates 62 at both ends of the linkage rod 61. The linkage plates 62 are in contact with the counterweight 58, and a connecting collar 63 is provided on the linkage plate 62, which is sleeved on the counterweight 58.

[0043] The balancing housing 51 is rotatably connected to the second support rotating block 46 via a rotating shaft, and the balancing housing 51 is locked to the support housing 41 by inserting the second electric insertion rod 59 into the second fixed groove 47. The second electric insertion rod 59 is also controlled by transmitting electrical signals through the electric control button 45, but the control panel on the harvester body 1 needs to switch the signals of the first electric insertion rod 42 and the second electric insertion rod 59. The electric control button 45 can only retract the first electric insertion rod 42 and the second electric insertion rod 59 at the same time. When the harvester needs to harvest soybeans or corn on sloping fields (here, sloping fields refer to fields where it has been determined that the sloping roots of soybeans or corn need to be cut, where soybeans and corn still grow vertically upwards, but the roots are sloping, this refers to harvesting such sloping roots), the control system is switched from the first electric insertion rod 42 to the second electric insertion rod 59. When button 45 is pressed, the second electric insert 59 is pulled out from the second fixed slot 47, and the first electric insert 42 will not be displaced. In this way, when the balancing component 5 is working, it adjusts the displacement of the balancing housing 51. The adjusting component 4 and the harvesting device 3 will not be driven to move by the balancing component 5 at this time. When the support housing 41 is in a vertical state, the electric control button 45 is no longer pressed down. At this time, the second electric insert 59 is reinserted into the second fixed slot 47 and locked. At this time, the control signal is switched from the second electric insert 59 back to the first electric insert 42. At this time, the harvesting device 3 is in a tilted state, and the balancing component 5 and the adjusting component 4 are based on this tilted state. When the tilted state is adjusted at an angle, the balancing component 5 and the adjusting component 4 will be triggered. The support housing 41 has a certain space inside for the balancing component 5 to adjust the angle. At the same time, the support housing 41 is also provided with an annular groove so that the balancing motor 53 can move along with it.

[0044] When the electronic control button 45 is pressed, both the left and right electronic control buttons 45 drive the balancing motor 53. However, the left electronic control button 45 drives the balancing motor 53 in reverse, while the right electronic control button 45 controls the balancing motor 53 to rotate forward. When the balancing motor 53 rotates, it drives the rotating rod 54 to rotate. The rotating rod 54 is equipped with two take-up rollers 55, and the traction rope 56 wound on the two take-up rollers 55 has opposite winding directions. When the rotating rod 54 rotates, it drives the two take-up rollers 55 to rotate. One of the two take-up rollers 55 must be winding up the traction rope 56, and the other must be unwinding the traction rope 56. The connecting rod 57 pulls the counterweight 58 along the moving roller 52 towards the center point of the balance housing 51. This counterweight 58, through the linkage rod 61, pushes the other counterweight 58 away from the center point of the balance housing 51. Since the traction rope 56 above the farther counterweight is constantly being released, the winding roller 55 wound around the two traction ropes 56 rotates at the same speed, ensuring that both traction ropes 56 remain taut. Regardless of which side's traction rope 56 is winding, it will pull the counterweight 58 immediately. The balance can be adjusted by changing the position of the two counterweights 58. The center of gravity on both sides of the balance housing 51, or support housing 41, is adjusted to adjust the center of gravity of the harvesting device 3. The entire balance assembly 5 is similar to a seesaw. The linkage rod 61 is slidably connected to the balance housing 51 and connected to the balance counterweights 58 on both sides through the connecting collar 63. The linkage rod 61 serves two purposes: it drives the balance counterweights 58 on both sides to move synchronously and it also maintains the stability of the balance counterweights 58, preventing the balance counterweights 58 from tilting when the traction rope 56 is pulled. (The sliding stroke of the linkage rod 61 on the balance housing 51 is adapted to the movement trajectory of the balance counterweights 58. Limiting blocks are provided at both ends of the linkage rod 61. When the balance counterweights 58 are pulled, the limiting blocks are adjusted accordingly.) When the device moves to the extreme position near or far from the center point of the balance housing 51, the limit block can prevent the linkage rod 61 from continuing to slide, preventing the balance counterweight 58 from disengaging from the moving roller 52 and avoiding failure of the balance component. The balance motor 53 is equipped with a speed adjustment module, which can adaptively adjust the speed according to the tilt signal intensity transmitted by the electronic control button 45 (such as the pressure value of the support rod 43 pressing the electronic control button 45). The greater the tilt of the vehicle body, the faster the motor speed, and the speed of the traction rope 56 is increased synchronously to ensure rapid correction of the angle of the harvesting equipment. When the harvesting equipment 3 is close to the balance state, the motor automatically reduces the speed to avoid overcorrection due to inertia.
