Description

Technical Field

[0001] This utility model relates to the field of seeder technology, and in particular to a ridge correction and transfer device and a seeder for a self-propelled Chinese medicinal herb seeder. Background Technology

[0002] With the large-scale development of the Chinese medicinal herb planting industry, mechanized sowing technology has become a key means to improve operational efficiency and ensure planting quality. Self-propelled seeders are widely used in ridge sowing due to their flexibility and automation advantages. However, existing self-propelled Chinese medicinal herb seeders still face significant technical bottlenecks in actual operation:

[0003] Firstly, the ability to correct the trajectory on the ridges is insufficient: the sowing of some Chinese medicinal herbs requires high precision in row spacing and ridge height, but traditional seeders are prone to trajectory deviations during operation due to uneven ground and uneven soil resistance. Existing technologies mostly rely on manual intervention or mechanical guiding devices for correction. The former is inefficient and labor-intensive, while the latter has a complex structure and poor adaptability, making it difficult to achieve rapid and accurate path adjustment, which directly affects the uniformity of sowing and the germination rate.

[0004] Secondly, cross-row transport is inefficient: after completing a single row, the seeder needs to frequently cross the ridges to work in the next area or return for transport. Traditional solutions typically use a hydraulic lifting chassis or additional traction equipment, but hydraulic systems are expensive and complex to maintain, while traction transport requires additional power equipment, resulting in low equipment utilization and increased operating costs. In addition, conventional lifting mechanisms have low integration with the sowing function, are bulky, and are prone to crushing and damaging the seedbed during frequent lifting.

[0005] Third, functional expandability is limited: most existing seeders have a fixed structure and low degree of functional modularity.

[0006] Therefore, existing medicinal herb seeders still have many shortcomings and need further improvement. Utility Model Content

[0007] In view of this, the present invention provides a ridge correction and transfer device and a seeder for a self-propelled Chinese medicinal herb seeder, which can correct the seeding path of the self-propelled Chinese medicinal herb seeder and realize cross-ridge transfer.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A ridge-level correction and transfer device for a self-propelled Chinese medicinal herb seeder includes two correction and transfer units symmetrically arranged on the left and right sides of the seeder. Each correction and transfer unit includes a detachable connecting bracket, a traveling mechanism, and a lifting mechanism. The detachable connecting bracket is installed on the side of the seeder and is detachable. The lifting mechanism is installed on the detachable connecting bracket and can drive the traveling mechanism to lift or lower. When the seeder is sowing, the lifting mechanism drives the traveling mechanism to lift so that the traveling mechanism is above the bottom of the furrow. When the seeder's trajectory deviates, the lifting mechanism drives the traveling mechanism to lower to the bottom of the furrow, and the two traveling mechanisms move forward at different speeds to correct the seeder's trajectory. When the seeder crosses a ridge or changes work areas, the lifting mechanism drives the traveling mechanism to lower to the ground and lifts the seeder above the furrow, and the two traveling mechanisms move forward to transfer the seeder.

[0010] Furthermore, the traveling mechanism also includes a geared motor for driving the front wheels to rotate. The geared motor is connected to the front wheel drive and can drive the front wheels to rotate.

[0011] Furthermore, the lifting mechanism includes a lifting electric cylinder, which is inverted. The cylinder body of the lifting electric cylinder is fixed to a detachable connecting bracket. The lifting electric cylinder is equipped with an electric push rod that can move up and down, and the end of the electric push rod is connected to the connecting crossbeam.

[0012] Furthermore, the electric push rod is hinged to the connecting crossbeam.

[0013] Furthermore, the lifting mechanism also includes two sliding pairs, which are respectively disposed on the left and right sides of the lifting electric cylinder, and the connecting beam and the detachable connecting bracket are slidably connected via the two sliding pairs.

[0014] Furthermore, the sliding pair includes a longitudinal beam, a lower limiting plate, a limiting rod, a slide rail, and sliders. The lower limiting plate is installed at the bottom of the detachable connecting bracket, and the front end of the lower limiting plate is positioned above the connecting crossbeam. The front end of the lower limiting plate has a square hole, through which the lower end of the longitudinal beam passes and is fixedly connected to the connecting crossbeam. The upper end of the longitudinal beam extends upward, and the limiting rod is installed at the top of the longitudinal beam. Two sliders are provided, and these two sliders are installed on the limiting rod. The slide rail is fixedly installed on the detachable connecting bracket and is arranged parallel to the electric push rod. The two sliders are slidably connected to the slide rail.

[0015] Furthermore, the detachable connecting bracket includes a top plate, side plates, an L-shaped plate, a rear plate, and two triangular brackets. Two side plates are provided and arranged opposite each other. The four edges of each side plate are bent inwards, designated as the upper folded edge, lower folded edge, front folded edge, and rear folded edge. A triangular bracket is fixedly mounted on the inner side of each side plate. The transverse beam of this triangular bracket and the upper folded edge have slots. The left and right ends of the top plate are respectively inserted into two slots and fixedly connected to the transverse beam of the triangular bracket. The lifting electric cylinder is inverted and fixedly mounted on the underside of the top plate. The top plate; the vertical plate of the L-shaped plate is installed on the front folded edge of the two side plates, the horizontal plate of the L-shaped plate is installed on the lower folded edge of the two side plates, and the slide rail is installed on the front folded edge of the side plate; the rear plate is fixed to the rear folded edge of the two side plates, and the rear folded edge of the side plate has a first bolt hole along the length direction; the triangular bracket is welded from three square tubes, and the vertical beam of the triangular bracket has a second bolt hole corresponding to the first bolt hole; the side of the seeder is provided with a third threaded hole corresponding to the second bolt hole; the detachable connecting bracket is connected to the seeder by bolts.

[0016] Furthermore, the ridge-mounted correction and transfer device also includes a DC battery, which is mounted on a detachable connecting bracket and electrically connected to the lifting cylinder and the reduction motor respectively.

[0017] Another technical solution adopted by this utility model is:

[0018] A seeder includes a ridge-correcting and transporting device for a self-propelled Chinese medicinal herb seeder.

[0019] The beneficial effects of this utility model compared with the prior art are:

[0020] 1. The correction and transfer device of this utility model can correct the path of the seeder and transfer the seeder by lifting the electric cylinder and the front and rear wheels. It not only improves the accuracy of sowing and avoids damage to the seed bed, but also has a simple overall structure and is easy to operate.

[0021] 2. The correction and transfer device of this utility model is modularly designed and detachably connected to the seeder, eliminating the need for large-scale modifications to the existing seeder and offering strong versatility. When the correction and transfer device malfunctions, it can be removed from the seeder for repair without affecting the seeder's operation. Attached Figure Description

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Figure 1 and Figure 2 This diagram illustrates the structure of a ridge-correcting and transporting device for a self-propelled Chinese medicinal herb planter according to this embodiment. Figure 1 and Figure 2 The ridge correction and transfer device in this embodiment includes two correction and transfer units, which are symmetrically arranged on the left and right sides of the seeder 4 and are detachably connected to the seeder 4. Figure 2Each modified transfer unit includes a detachable connecting bracket 1, a traveling mechanism 2, and a lifting mechanism 3. The detachable connecting bracket 1 is installed on the side of the seeder 4 and is detachable; the lifting mechanism 3 is installed on the detachable connecting bracket 1 and can drive the traveling mechanism 2 to lift or lower.

[0036] The seeder 4 has three operating modes: normal sowing mode, path correction mode, and seeder transport mode. When the seeder 4 is in sowing mode, the two lifting mechanisms 3 drive the corresponding traveling mechanisms 2 upwards. At this time, the two traveling mechanisms 2 are above the bottom of the furrow. The seeder 4 relies on its own power system to travel along the furrow and sow seeds. The two traveling mechanisms 2 move forward with the seeder 4 without participating in power output, thus avoiding interference with the sowing depth and stability. When a deviation in the sowing trajectory is observed, the seeder 4's sowing mode is switched to path correction mode. Specifically, the two lifting mechanisms 3 drive the corresponding traveling mechanisms 2 downwards to the bottom of the furrow. At this time, the seeder 4's own power system stops operating, and the seeder 4 moves forward relying on the two traveling mechanisms 2. The two traveling mechanisms 2 move at different speeds and correct the attitude of the seeder 4, making the seeder 4's forward direction parallel to the furrow, thereby correcting the seeder 4's travel trajectory and improving sowing accuracy. When the seeder 4 needs to cross ridges or move to a different work area, the seeder 4's sowing mode is switched to the seeder 4 transfer mode. Specifically, the lifting mechanism 3 drives the traveling mechanism 2 to lower to the ground to the limit position, and lifts the seeder 4 to 20-30cm above the bottom of the furrow. The seeder 4's own power system stops running, and the seeder 4 relies on the two traveling mechanisms 2 to cross ridges or move to a different work area. Since the seeder 4 has left the furrow, it will not crush the furrow, thus achieving zero-crushing rapid transfer.

[0037] Therefore, it can be seen that the path correction of the seeder 4 and the transfer of the seeder can be realized through the lifting mechanism 3 and the traveling mechanism 2 in this embodiment. This not only improves the accuracy of sowing and avoids damage to the seed bed, but also has a simple overall structure and is easy to operate.

[0038] like Figure 2As shown, the traveling mechanism 2 in this embodiment includes a front wheel 21, a rear wheel 22, a connecting beam 23, and a reduction motor 24 for driving the front wheel 21 to rotate. The front wheel 21 is rotatably mounted on the front end of the connecting beam 23. The motor housing of the reduction motor 24 is fixedly mounted on the connecting beam 23. The motor shaft of the reduction motor 24 is fixedly connected to the front wheel 21 and can drive the front wheel 21 to rotate. Thus, the front wheel 21 is the driving wheel of the traveling mechanism 2. The rear wheel 22 is rotatably mounted on the rear end of the connecting beam 23, and the rear wheel 22 is the driven wheel of the traveling mechanism 2. The lifting mechanism 3 is drivenly connected to the connecting beam 23. When the seeder 4 switches from the sowing mode to the path correction mode or the transfer mode, the lifting mechanism 3 drives the connecting beam 23 to move downward, and the front wheel 21 and the rear wheel 22 touch the ground. The geared motor 24 is powered by a 48V DC battery and is electrically connected to the battery. When the geared motor 24 is energized, the front wheel 21 rotates along the motor shaft of the geared motor 24, driving the entire seeder 4 forward. The starting of the geared motor 24 and the rotation speed of both geared motors 24 can be controlled by a remote control to suit different modes. Compared to traditional manual correction, this method eliminates the need for frequent driver stops for adjustments, enabling continuous operation. In other words, this embodiment achieves "correction while operating" via wireless remote control, allowing operators to remotely monitor within a 100m range, greatly improving operational efficiency.

[0039] like Figure 2As shown, the lifting mechanism 3 in this embodiment includes a lifting cylinder 31 and two sliding pairs 32. The cylinder body of the lifting cylinder 31 is fixedly mounted on the detachable connecting bracket 1. The lifting cylinder 31 is provided with an electric push rod 311 that can move up and down. The end of the electric push rod 311 is hinged to the connecting beam 23. The two sliding pairs 32 are respectively arranged on the left and right sides of the lifting cylinder 31. The connecting beam 23 and the detachable connecting bracket 1 are slidably connected via the two sliding pairs 32. The lifting cylinder 31 is also powered by a DC battery and is electrically connected to the DC battery. When the lifting mechanism 3 drives the traveling mechanism 2 to lower, the lifting cylinder 31 is energized, the electric push rod 311 extends out of the lifting cylinder 31, and the electric push rod 311 drives the front wheel 21 and the rear wheel 22 to move down through the connecting beam 23, thereby achieving the contact of the front wheel 21 and the rear wheel 22 with the ground. When the lifting mechanism 3 drives the traveling mechanism 2 to lift, the lifting cylinder 31 is energized, and the electric push rod 311 retracts. The electric push rod 311 drives the front wheel 21 and rear wheel 22 to move upward through the connecting beam 23, thus making the front wheel 21 and rear wheel 22 higher than the furrow. Therefore, the design of the lifting cylinder 31 can achieve the lifting or lowering of the front wheel 21 and rear wheel 22. When the lifting cylinder 31 drives the connecting beam 23 to lift or lower, the gravity on both sides of the lifting cylinder 31 and the connecting beam 23 may be different, causing the connecting beam 23 to tilt. The sliding pair 32 has a guiding and limiting function, which ensures that the height on both sides of the connecting beam 23 is consistent, and the front wheel 21 and rear wheel 22 can touch the ground synchronously after lowering. Compared with the traditional hydraulic lifting scheme, this embodiment uses an electric push rod for direct lifting, eliminating complex components such as hydraulic pump stations and oil circuits, greatly reducing the overall weight, improving the lifting response speed, and reducing power consumption. Meanwhile, the four-wheel coordinated lifting mechanism can evenly distribute the load and avoid compaction of the seedbed caused by stress concentration at a single point.

[0040] like Figure 2 and Figure 5 As shown, a connecting sleeve 25 is fitted onto the connecting crossbeam 23. The top of the connecting sleeve 25 has a connecting seat 26 and a pin 27. The pin 27 is mounted on the connecting seat 26. A ball bearing 312 is located at the lower end of the electric push rod 311 and is fitted onto the pin 27. This achieves the connection between the electric push rod 311 and the connecting crossbeam 23. The design of the connecting sleeve 25 avoids drilling holes in the connecting crossbeam 23, ensuring the rigidity of the connecting crossbeam 23 and preventing bending deformation over long-term use. Simultaneously, during the lifting or lowering of the connecting crossbeam by the lifting cylinder, the hinged connection design prevents the electric push rod from bending due to torque or causing damage to the lifting cylinder.

[0041] The connecting sleeve 25 consists of an upper pressure plate 251, a lower pressure plate 252, and four connecting bolts 253. The upper pressure plate 251 and the lower pressure plate 252 are located on the upper and lower sides of the connecting beam 23, respectively. The four connecting bolts 253 are connected to the upper pressure plate 251 and the lower pressure plate 252, so that the upper pressure plate 251 and the lower pressure plate 252 clamp the connecting beam 23, thereby realizing the connection between the connecting sleeve 25 and the connecting beam 23.

[0042] like Figure 2 As shown, the sliding pair 32 in this embodiment includes a longitudinal beam 321, a lower limiting plate 324, a limiting rod 325, a slide rail 322, and a slider 323. The lower limiting plate 324 is installed at the bottom of the detachable connecting bracket 1, and the front end of the lower limiting plate 324 extends above the connecting crossbeam 23. The front end of the lower limiting plate 324 has a square hole. The lower end of the longitudinal beam 321 passes through the square hole and is fixedly connected to the connecting crossbeam 23. The upper end of the longitudinal beam 321 extends upward. The limiting rod 325 is installed at the top of the longitudinal beam 321. There are two sliders 323, which are installed on the limiting rod 325. The slide rail 322 is fixedly installed on the detachable connecting bracket 1 and is arranged parallel to the electric push rod 311. The two sliders 323 are slidably connected to the slide rail 322. When the lifting cylinder 31 drives the front wheel 21 and rear wheel 22 to lift or lower via the connecting beam 23, the slider 323 moves along the length of the slide rail 322. The slide rail 322 limits the connecting beam 23 through the slider 323 and the longitudinal beam 321, thereby preventing the connecting beam 23 from tilting. When the electric push rod 311 extends a certain length, the lower end of the limiting rod 325 abuts against the lower limiting plate 324. At this time, the electric push rod 311 cannot extend further. In other words, the cooperation between the lower limiting plate 324 and the limiting rod 325 can prevent the lifting cylinder 31 from exceeding its stroke, ensuring the service life of the lifting cylinder 31.

[0043] like Figure 2 , Figure 4 and Figure 6 As shown, the detachable connecting bracket 1 in this embodiment includes a top plate 11, side plates 12, an L-shaped plate 13, a rear plate 14, and two triangular brackets 15. Two side plates 12 are provided and arranged opposite each other. The four edges of each side plate 12 are bent inwards, designated as an upper folded edge 121, a lower folded edge 122, a front folded edge 123, and a rear folded edge 124. A triangular bracket 15 is fixedly mounted on the inner surface of each side plate 12. The transverse beam of the triangular bracket 15 and the upper folded edge 121 have slots, resulting in two slots on each of the two side plates 12. The left and right ends of the top plate 11 are respectively inserted into the two slots and fixedly connected to the transverse beam of the triangular bracket 15, thereby achieving a fixed connection between the top plate 11 and the two side plates 12. Figure 2It can be seen that the width of the top plate 11 is wider than the width of the side plate 12, so that the front end of the top plate 11 protrudes beyond the side plate 12. The lifting cylinder 31 is placed upside down on the underside of the top plate 11 and fixed to the front end of the top plate 11 with bolts.

[0044] like Figure 6 As shown, the vertical plate of the L-shaped plate 13 is mounted on the front folded edge 123 of the two side plates 12, serving as the front plate; the horizontal plate of the L-shaped plate 13 is mounted on the lower folded edge 122 of the two side plates 12, serving as the bottom plate. That is, the front plate and bottom plate of the detachable connecting bracket 1 are made as one piece, which increases the strength of the detachable connecting bracket 1. The slide rail 322 is mounted on the front folded edge 123 of the side plate 12. Figure 4 As shown, the rear plate 14 is fixed to the rear folded edge 124 of the two side plates 12. The rear folded edge 124 of the side plates 12 has first bolt holes along its length. The triangular bracket 15 is welded from three square tubes. The vertical beam of the triangular bracket 15 has second bolt holes corresponding to the first bolt holes. The side of the seeder 4 has third threaded holes corresponding to the second bolt holes. The detachable connecting bracket 1 and the seeder 4 are connected by bolts. This achieves a detachable connection between the detachable connecting bracket 1 and the seeder 4.

[0045] In this embodiment, the correction and transfer unit can be quickly assembled with the seeder via the detachable connecting bracket 1 without damaging the original seeder structure, reducing modification costs and increasing equipment reuse rate. When the correction and transfer unit malfunctions, it can be removed from the seeder for repair without affecting the seeder's operation.

[0046] Example 2:

[0047] See Figure 1 The seeder in this embodiment includes the ridge correction and transfer device as described above.

[0048] The following is combined with Figures 1 to 4 This invention provides a detailed description of the working principle and workflow of a ridge-correcting and transporting device for a self-propelled Chinese medicinal herb planter, as well as the planter itself.

[0049] When the seeder 4 is in sowing mode, both the front wheel 21 and the rear wheel 22 are higher than the furrow. The seeder 4 moves along the furrow and sows seeds using its own power system. The two traveling mechanisms 2 move with the seeder 4 but do not participate in power output to avoid interfering with the sowing depth and stability. When a deviation in the sowing trajectory is observed, the seeder 4's sowing mode is switched to path correction mode. The seeder 4's own power system stops operating, the two lifting cylinders 31 are energized, and the electric push rods 311 extend from the lifting cylinders 31. The electric push rods 311 drive the front wheel 21 and the rear wheel 22 to move down through the connecting beam 23 until the front wheel 21 and the rear wheel 22 touch the ground. The two reduction motors 24 are energized, and the front wheel 21 rotates with the motor shaft of the reduction motor 24, driving the entire seeder forward. The two front wheels 21 move at different speeds and correct the posture of the seeder body, making the forward direction of the seeder 4 parallel to the furrow, thereby correcting the travel trajectory of the seeder 4 and improving the sowing accuracy. When the travel trajectory of the seeder 4 is corrected, the lifting cylinder 31 is energized, the electric push rod 311 retracts the lifting cylinder 31, and the electric push rod 311 drives the front wheel 21 and the rear wheel 22 to move upward through the connecting beam 23, so that the front wheel 21 and the rear wheel 22 are higher than the furrow.

[0050] When the seeder 4 needs to cross ridges or move to a different work area, its seeding mode is switched to its transfer mode. The seeder 4's own power system stops operating, the two lifting cylinders 31 are energized, and the electric push rod 311 extends out of the lifting cylinders 31. The electric push rod 311 drives the front wheel 21 and rear wheel 22 to move down through the connecting beam 23. The front wheel 21 and rear wheel 22 touch the ground, raising the seeder 4 to 20-30cm above the furrow. The seeder 4's own power system stops operating. The two reduction motors 24 are energized, and the front wheel 21 rotates with the motor shaft of the reduction motor 24, driving the entire seeder 4 forward. The seeder 4 crosses ridges or moves to a different work area using the two front wheels 21 and the two rear wheels 22. Since the seeder has left the furrow, it will not compact the furrow, thus achieving rapid transfer with zero compaction.

[0051] As can be seen, this embodiment solves the technical pain points of traditional seeders, such as the lagging trajectory correction, reliance on auxiliary equipment for transportation, and poor compatibility of modification, through modular electromechanical design. While ensuring the original machine's operating performance, it significantly improves the accuracy, efficiency, and economy of seeding medicinal herbs, and has broad prospects for industrial application.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
