Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a seeding leg anti-congestion device and an anti-congestion no-till seeder. Background Technology

[0002] Because crop stubble, weeds and other obstacles are irregularly laid on the ground, especially large obstacles, when using a combined seeder for fertilization and sowing operations, these obstacles will accumulate at the sowing legs. This prevents the soil turned over by the sowing legs from effectively covering the fallen seeds, causing the seeds to be exposed on the ground surface and affecting the sowing effect. Therefore, a device is needed to clear the obstacles at the sowing legs. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a seeding leg anti-congestion device and an anti-congestion no-till seeder. By adding an anti-congestion device between the fertilization mechanism and the seeding mechanism, the accumulated debris at the seeding leg is cleared, thereby improving the seeding effect.

[0004] To solve the above-mentioned technical problems, the present invention provides a technical solution: a seeding leg anti-congestion device, comprising a transmission mechanism and a cleaning mechanism, wherein the two ends of the transmission mechanism are respectively linked to a power source and a cleaning mechanism, for transmitting power from the power source to the cleaning mechanism, characterized in that: the cleaning mechanism comprises a turntable and a chain, the turntable is disposed on one or both sides of one end of the transmission mechanism and is linked to the transmission mechanism, at least one chain is evenly connected on the turntable, the chain rotates around the axis of the turntable under the drive of the turntable, and the axis of the turntable is parallel and / or perpendicular to the forward direction of the seeding leg.

[0005] Furthermore, the transmission mechanism is provided with a telescopic rod on the side near the turntable for adjusting the height of the turntable, so that the chain just touches or does not touch the ground when rotating. One end of the telescopic rod is hinged to the transmission mechanism, and the other end of the telescopic rod is hinged to the mounting base.

[0006] Furthermore, the two turntables on both sides of the transmission mechanism rotate in the same or opposite directions.

[0007] Furthermore, the chain is hinged to the turntable via a fixing plate.

[0008] To solve the above-mentioned technical problems, the present invention provides a technical solution: an anti-congestion no-till seeder, comprising a seeder body and an anti-congestion device, wherein the seeder body comprises a frame, a fertilization mechanism and a sowing mechanism, and the anti-congestion device is a sowing leg anti-congestion device as described above, characterized in that: the anti-congestion device is disposed on the frame between the fertilization mechanism and the sowing mechanism, and corresponds to the front and rear of the sowing mechanism;

[0009] The power source and mounting base of the anti-congestion device are mounted on the frame.

[0010] Furthermore, a safety guard plate is installed on the frame on the upper side of the anti-congestion device.

[0011] Furthermore, the sowing mechanism includes a sowing leg, a seed metering device, a ground wheel, and a soil covering and pressing device. The sowing leg, seed metering device, and soil covering and pressing device are fixed sequentially on a connecting frame. The connecting frame is hinged to the machine frame via a four-bar linkage. The ground wheel drives the rotating drum to rotate via a gearbox and a transmission assembly. Two seed metering devices are located at both ends of the rotating drum, and the rotating shafts on the two seed metering devices are detachably and coaxially inserted into the multi-faceted holes at both ends of the rotating drum. There is a radial deflection angle between the multi-faceted holes at both ends of the rotating drum, so that the two seed metering devices can perform staggered seeding.

[0012] Furthermore, the mounting base is disposed on the connecting bracket.

[0013] Furthermore, the soil compaction device includes soil compaction wheels and a lifting frame. One end of the lifting frame is connected to the connecting frame. Two soil compaction wheels are arranged in a V-shape and rotate on both sides of the other end of the lifting frame. The lifting frame is provided with an arc-shaped limiting hole, and multiple limiting grooves distributed along the inner arc are provided in the arc-shaped limiting hole. An angle adjustment handle is connected to the rotating shaft of the soil compaction wheel. The angle adjustment handle is provided with a strip-shaped limiting hole. Limiting bolts pass through the strip-shaped limiting hole and the arc-shaped limiting hole. By embedding the limiting bolts into different limiting grooves, the two V-shaped soil compaction wheels can be rotated back and forth and limited as a whole.

[0014] Furthermore, a drip irrigation tape laying device corresponding to the sowing mechanism is provided at the rear of the seeder body for laying drip irrigation tape.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This application uses a turntable to drive a chain to rotate, thereby clearing away large debris accumulated at the sowing leg. The axis of the turntable is parallel or perpendicular to the forward direction of the sowing leg. One method clears debris after it has accumulated, while the other method clears debris before it has accumulated. Both methods can be used simultaneously to ensure effective debris clearing, thus solving the problem of obstacles accumulating at the sowing leg and affecting the sowing effect during sowing operations.

[0017] 2. In this application, the telescopic rod can adjust the height of the turntable according to different sowing depths, so that the chain just touches the ground or does not touch the ground when it rotates. This ensures that debris on the ground is thrown out and cleared, especially large debris, while minimizing damage to the soil layer and reducing dust. Since the fertilization, anti-clogging device and sowing are on the same axis, it prevents the chain from forming grooves on the ground that would dig up fertilizer and affect subsequent sowing and covering.

[0018] 3. In this application, there are two turntables on both sides of a transmission mechanism to increase the debris removal effect. The two turntables on both sides of the transmission mechanism rotate in the same or opposite directions. When the axis of the turntable is parallel to the forward direction of the seeding leg, the debris is thrown to the left and right sides of the seeding leg. When the axis of the turntable is perpendicular to the forward direction of the seeding leg, the debris is thrown to the rear side of the seeding leg to prevent debris from accumulating at the seeding leg.

[0019] 4. The chain described in this application is hinged to the turntable via a fixing plate, which facilitates chain replacement. The chain has flexible characteristics and will bounce away from hard objects such as stones and bricks when rotating to clean up debris, without causing damage to the turntable and transmission mechanism. The chain is also less likely to get tangled in grass, and the seed metering device has a raised design with a large ground clearance and good passability.

[0020] 5. In this application, a safety guard plate is installed on the frame above the turntable in the anti-congestion device to provide shielding and protection, preventing chain breakage or accidental splashing of debris from causing safety hazards.

[0021] 6. When used in conjunction with existing seeders and drip irrigation tape laying devices, this application can simultaneously perform fertilization, sowing, and drip irrigation tape laying operations, thereby improving farming efficiency.

[0038] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0039] Example 1

[0040] like Figures 1-5 As shown, a sowing leg anti-congestion device is provided, including a transmission mechanism A and a cleaning mechanism C. The two ends of the transmission mechanism A are respectively linked to a power source and the cleaning mechanism C, and are used to transmit power from the power source to the cleaning mechanism C. The cleaning mechanism C includes a turntable C1 and a chain C2. The turntable C1 is set on one or both sides of one end of the transmission mechanism A and is linked to the transmission mechanism A. At least one chain C2 is evenly connected on the turntable C1. The chain C2 rotates around the axis C3 of the turntable C1 under the drive of the turntable C1. The axis C3 of the turntable C1 is parallel and / or perpendicular to the forward direction of the sowing leg F1.

[0041] The power source transmits driving force to the turntable C1 through the transmission mechanism A. The turntable C1 drives the chain C2 to rotate, thereby clearing the debris accumulated at the sowing leg F1. There are two turntables C1 on both sides of the transmission mechanism A, which increases the debris removal effect. When the axis C3 of the turntable C1 is parallel to the forward direction of the sowing leg F1, it clears the debris after accumulation. When the axis C3 of the turntable C1 is perpendicular to the forward direction of the sowing leg F1, it clears the debris in front of the accumulation (in front of the sowing leg F1). At the same time, the two can be arranged simultaneously to ensure the debris removal effect, thereby solving the problem of obstacles accumulating at the sowing leg F1 and affecting the sowing effect during the sowing operation.

[0042] Example 2

[0043] like Figures 1-3 As shown, this embodiment is obtained by increasing the number of technical features such as telescopic rod C4 on the basis of embodiment one. The other technical features are the same as those in embodiment one, and the similarities will not be repeated here. The difference between this embodiment and embodiment one is that: a telescopic rod C4 for adjusting the height of turntable C1 is provided on the side of transmission mechanism A near turntable C1. One end of telescopic rod C4 is hinged to transmission mechanism A, and the other end of telescopic rod C4 is hinged to mounting base C5.

[0044] In this embodiment, the telescopic rod C4 is used to adjust the height of the turntable C1 according to different sowing depths, so that the chain C2 just touches or does not touch the ground when it rotates. This ensures that debris on the ground is thrown out and cleared, especially large debris that is easy to clog at the sowing leg, minimizing damage to the soil layer and reducing dust. Since the fertilization, anti-clogging device and sowing are on the same axis C3, it prevents the chain C2 from forming grooves on the ground that would dig up the fertilizer and affect subsequent sowing and covering.

[0045] Example 3

[0046] like Figure 3As shown, this embodiment is obtained by increasing the number of technical features such as the fixing plate C6 on the basis of embodiment two. The remaining technical features are the same as those in embodiment two, and the similarities will not be repeated here. The difference between this embodiment and embodiment two is that the rotation directions of the two turntables C1 on both sides of the transmission mechanism A are the same or opposite; the chain C2 is hinged to the turntable C1 through the fixing plate C6.

[0047] In this embodiment, the two turntables C1 on both sides of the transmission mechanism A rotate in the same or opposite directions. When the axis C3 of the turntable C1 is parallel to the forward direction of the sowing leg F1, the debris is thrown out to the left and right sides of the sowing leg F1. When the axis C3 of the turntable C1 is perpendicular to the forward direction of the sowing leg F1, the debris is thrown out to the rear side of the sowing leg F1 to prevent the debris from accumulating at the sowing leg F1.

[0048] Among them, the chain C2 is hinged to the turntable C1 through the fixing plate C6, which makes it easy to replace the chain C2. The chain C2 has flexible characteristics. When it encounters hard objects such as stones and bricks during rotation to clean up debris, it will bounce away and avoid them, so as not to damage the turntable C1 and the transmission mechanism A. The chain C2 is less likely to get tangled in grass, and the seed metering device F2 is designed with a higher ground clearance and good passability.

[0049] To better solve the aforementioned technical problems, the above-mentioned anti-congestion device for the seeding leg is combined with the existing seeder body with fertilization function to form another technical solution of this application. This technical solution is as follows: Figures 1-7 A congestion-resistant no-till planter includes a planter body and an anti-congestion device. The planter body includes a frame D, a fertilization mechanism E, and a sowing mechanism F. The anti-congestion device is a sowing leg anti-congestion device as described above. The anti-congestion device is installed on the frame D between the fertilization mechanism E and the sowing mechanism F, and is corresponding to the front and rear of the sowing mechanism F.

[0050] The power source and mounting base C5 in the anti-congestion device are set on the frame D. The power source is linked to the transmission mechanism A through the gearbox A1. The power source is an electric motor, a hydraulic motor, or the power output shaft of the tractor. Specifically, the gearbox A1 is linked to the power output shaft of the tractor. The gearbox A1 drives the turntable C1 to rotate through the anti-congestion drive shaft A2 and the anti-congestion chain box A3 (at this time, the axis of the turntable C1 is perpendicular to the forward direction of the sowing leg F1. When it is necessary to make the axis of the turntable C1 parallel to the forward direction of the sowing leg F1, it is only necessary to add a commutator between the turntable C1 and the anti-congestion chain box A3). At the same time, when the height of the turntable C1 is adjusted, the anti-congestion chain box A3 can rotate around the anti-congestion drive shaft A2.

[0051] The seeder body is equipped with a drip irrigation tape laying device (not shown in the figure, but a commonly used laying device in the prior art) at the rear of the seeder body. The anti-clogging device works in conjunction with the seeder and drip irrigation tape laying device with fertilization function in the prior art, and can perform fertilization, sowing and drip irrigation tape laying operations at the same time, thereby improving the efficiency of cultivation.

[0052] Among them, a safety guard plate (not shown in the figure) is installed on the frame D above the anti-congestion device. The safety guard plate does not affect the rotation of chain C2 and the passage of debris, and plays a role in shielding and protecting against chain C2 breakage or accidental splashing of debris, which may cause safety hazards.

[0053] The sowing mechanism F includes sowing legs F1, seed metering devices F2, ground wheels F3, and soil covering and compaction devices F4. The sowing legs F1, seed metering devices F2, and soil covering and compaction devices F4 are sequentially fixed on a connecting frame F5. The connecting frame F5 is hinged to the machine frame D via a four-bar linkage F6. The ground wheels F3 drive the rotating drum F9 to rotate via a gearbox F7 and a transmission assembly F8. Two seed metering devices F2 are located at both ends of the rotating drum F9, forming small double-row sowing. The rotating shafts on the two seed metering devices F2 are detachable and coaxially inserted into the multi-faceted holes at both ends of the rotating drum F9. A radial deflection angle exists between the multi-faceted holes at both ends of the rotating drum F9, allowing the two seed metering devices F2 to stagger the sowing process, with the seeds falling into the soil via the two sowing legs F1. The structure is simple and easy to disassemble. The radial deflection angle between the multi-faceted holes forms small double-row triangular sowing, eliminating the need to modify or adjust the seed metering devices F2.

[0054] Meanwhile, the mounting base C5 can be set on the connecting frame F5. During sowing, due to the hinge action of the four-link F6, the turntable C1 can float up and down with the connecting frame F5. Since the sowing depth is relatively fixed according to the flatness of the ground, the distance between the turntable C1 and the ground is relatively stable, ensuring the stability of removing debris and preventing the chain C2 from contacting the soil layer too much and damaging the soil layer.

[0055] When the axis C3 of the turntable C1 is perpendicular to the forward direction of the sowing leg F1, the rotation path of the chain C2 passes between the two sowing legs F1 of the small double-row sowing, which can remove the debris wrapped around the two adjacent sowing legs F1; the sowing leg F1 is higher than the sowing leg F1 commonly used in the prior art, 20-30cm higher, preferably 25cm, to realize the height setting of the seed metering device F2, solve the congestion caused by the seed metering device being too low, and also facilitate the chain C2 to throw away the debris, with good passability.

[0056] The soil compaction device F4 includes soil compaction wheels F41 and a lifting frame F42 (interlocking sleeves with through holes through which pins pass). One end of the lifting frame F42 is connected to the connecting frame F5. The two soil compaction wheels F41 are arranged in a V-shape on both sides of the other end of the lifting frame F42. The lifting frame F42 is provided with an arc-shaped limiting hole F43, and multiple limiting grooves F44 distributed along the inner arc are provided in the arc-shaped limiting hole F43. An angle adjustment handle F45 is also included. Connected to the shaft of the soil compaction wheel F41, the angle adjustment handle F45 is provided with a strip-shaped limiting hole F46. Limiting bolts pass through the strip-shaped limiting hole F46 and the arc-shaped limiting hole F43. By embedding the limiting bolts into different limiting grooves F44, the two V-shaped soil compaction wheels F41 can be rotated back and forth and limited. The opening size of the soil compaction wheel F41 can be adjusted by rotating the two soil compaction wheels F41 as a whole to adapt to different soil compaction requirements.

[0057] In use, the frame D is connected to the hydraulic lifting wall of the tractor, and the power output shaft of the tractor is connected to the gearbox A1. The height of the turntable C1 is adjusted according to the sowing depth via the telescopic rod C4. The rotation angle of the two soil covering and compaction wheels F41 is adjusted according to the soil covering and compaction requirements via the angle adjustment handle F45. After that, it can be used in accordance with the usage method of the seeder in the existing technology.

[0058] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
