Description

[0001] This application is a divisional application of the patent application filed on May 24, 2024, with application number 202421152171.1 and patent title "A clearing blade, a seeding leg anti-congestion device and a triangular seeding no-till planter". Technical Field

[0002] This utility model relates to the field of agricultural machinery technology, specifically to a seeding leg anti-congestion device and a triangular seeding no-till seeder. Background Technology

[0003] 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. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model 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.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution: a clearing knife, characterized in that: it includes a knife body, the knife body has a flat plate structure, and after a cutting process, a shaft hole, a keyway and a blade are formed on the knife body. There are at least two blades, which are evenly distributed around the shaft hole. A wing plate is welded to the end of the blade. The two ends of the wing plate extend to one or both sides of the arc-shaped blade, and the plane formed by the wing plate is perpendicular to the plane formed by the knife body. When the wing plate is at the lowest end of the knife body, the wing plate has a horizontal included angle.

[0006] Furthermore, the blade has an arc-shaped structure, and the bending direction of the arc-shaped blades is consistent.

[0007] Furthermore, the blade tip is provided with a recess for placing the wing plate.

[0008] To solve the above-mentioned technical problems, another technical solution provided by this utility model is: a seeding leg anti-clog device, including a transmission mechanism and a clearing blade, wherein the clearing blade is a rotary tiller blade or a clearing blade as described above, characterized in that: the two ends of the transmission mechanism are respectively linked to a power source and the clearing blade, used to transmit the power from the power source to the clearing blade for rotation.

[0009] The transmission mechanism includes a driving rotating shaft, a chain box, and a driven rotating shaft. The driving rotating shaft and the driven rotating shaft are linked by the chain box. The driving rotating shaft is hinged to the frame through a bearing seat. The clearing blade is disposed at one or both ends of the driven rotating shaft. The axis of the clearing blade is parallel and / or perpendicular to the forward direction of the sowing leg.

[0010] Furthermore, the chain box is provided with a telescopic rod on the side near the clearing blade for adjusting the height of the clearing blade, so that the clearing blade just touches or does not touch the ground when rotating. One end of the telescopic rod is hinged to the chain box, and the other end of the telescopic rod is hinged to the mounting base on the frame.

[0011] To solve the above-mentioned technical problems, another technical solution provided by this utility model is: a triangular seedling fixed no-till seeder, including a seeder body and an anti-congestion device. The seeder body includes a frame, a fertilization mechanism and a sowing mechanism. The anti-congestion device is a sowing leg anti-congestion device as described above. The anti-congestion device is located on the frame between the fertilization mechanism and the sowing mechanism and is corresponding to the front and rear of the sowing mechanism.

[0012] The power source and mounting base of the anti-congestion device are mounted on the frame.

[0013] 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.

[0014] Furthermore, the mounting base is disposed on the connecting bracket.

[0015] 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.

[0016] 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.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This application uses a clearing blade to drive the wing plate to rotate, which clears large debris accumulated at the two sowing legs in the same sowing mechanism and breaks up larger clods of soil. The axis of the clearing blade is parallel or perpendicular to the forward direction of the sowing leg. One blade clears debris after it has accumulated, while the other clears debris before it has accumulated. Both blades can be deployed simultaneously to ensure effective debris clearing, thereby solving the problem of obstacles accumulating at the sowing leg and affecting the sowing effect during sowing operations.

[0019] 2. The rotation of the wing plate in this application increases the obstacle clearing effect. The wing plate is placed in the recessed platform on the blade, increasing the connection area between the wing plate and the blade and ensuring the connection strength between the two. The keyway prevents the blade body from sliding between the driven shaft and the blade body. After the cutting process, the blade body forms a shaft hole, keyway and arc-shaped blade. The integrated structure is easy to manufacture and can be directly cut. The curvature of the arc-shaped blade is in line with the rotation direction of the blade body. By rotating the outer curvature of the blade, loose debris can be pressed onto the ground, and then the wing plate can push the debris away. At the same time, the two ends of the wing plate extend to the sides of the arc-shaped blade, and the plane formed by the wing plate is perpendicular to the plane formed by the blade body, increasing the pushing area of ​​the arc-shaped blade. This makes it easier to push debris away and break up large clods of soil. In addition, the seed metering device is raised, with a large ground clearance and good passability.

[0020] 3. In this application, the telescopic rod can adjust the height of the clearing blade according to different sowing depths, so that the wing plate just touches the ground or does not touch the ground when rotating. This ensures that debris on the ground is thrown out and cleared, especially large debris, while minimizing damage to the soil layer. Since the fertilization, anti-clogging device and sowing are on the same axis, it prevents the wing plate from forming grooves on the ground, digging out fertilizer and affecting subsequent sowing and covering.

[0021] 4. In this application, two debris removal blades are set on both sides of the chain box to increase the debris removal effect. When the axis of the two debris removal blades on both sides of the chain box 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 debris removal blade 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.

[0022] 5. 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 embodiments of the present invention will now be described in detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0041] like Figure 1 As shown, a clearing knife is provided, including a knife body C1. The knife body C1 has a flat plate structure, and after a cutting process, a shaft hole C8, a keyway C9, and arc-shaped blades C2 are formed on the knife body C1. There are at least two (preferably three, four, or five) arc-shaped blades C2, which are evenly distributed around the shaft hole C8, and the bending direction of the arc-shaped blades C2 is consistent. A wing plate C6 is welded to the end of the arc-shaped blade C2. Both ends of the wing plate C6 extend to the sides of the arc-shaped blade C2, or one end of the wing plate C6 extends to one side of the arc-shaped blade C2. The plane formed by the wing plate C6 is perpendicular to the plane formed by the knife body C1. When the wing plate C6 is at the lowest end of the knife body C1, the wing plate C6 has a horizontal angle, which can be 0° or 30°-150°, specifically 45°, 60°, 90°, 120°, and 125°.

[0042] This application uses a clearing blade C to drive a rotating wing plate C6 (the wing plate C6 can be polygonal, preferably rectangular or hexagonal, wherein the length of the rectangle is three times the thickness of the curved blade C2, the width is twice the thickness of the curved blade C2, and the thickness is the same as the thickness of the curved blade C2). The wing plate C6 clears large debris accumulated at the two sowing legs F1 in the same sowing mechanism F. The keyway C9 prevents slippage between the blade body C1 and the driven drive shaft A3. After a cutting process, the blade body C1 has a shaft hole C8, a keyway C9, and a curved blade C2. The integrated structure is easy to manufacture; it can be directly cut and manufactured. The curved blade C2 has an arc... The rotation direction of the blade C1 is aligned with that of the rotating blade C2. The outer arc of the rotating blade C2 can press loose debris onto the ground, and then the wing plate C6 will push the debris away. At the same time, the two ends of the wing plate C6 extend to the sides of the curved blade C2, and the plane formed by the wing plate C6 is perpendicular to the plane formed by the blade C1, increasing the pushing area of ​​the curved blade C2. This makes it easier to push away debris and break up large clods of soil. In addition, the seed metering device F2 is designed with a large ground clearance and good passability. By changing the horizontal angle of the wing plate C6 when it is at the lowest point of the blade C1, it is easier to push away debris, and the wind force generated by the wing plate C6 during rotation can also be adjusted to promote the movement of debris. Example 2

[0043] like Figure 1 As shown, this embodiment is obtained by adding technical features such as the recessed platform C7 on the basis of embodiment one. The remaining 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 the end of the arc-shaped blade C2 is provided with a recessed platform C7 for placing the wing plate C6.

[0044] In this embodiment, the wing plate C6 is placed inside the recessed platform C7 on the blade, increasing the connection area between the wing plate C6 and the blade and ensuring the connection strength between the two.

[0045] The technical solution formed by the above embodiments, in combination with the transmission mechanism, forms another technical solution disclosed in this application. The technical solution is: a seeding leg anti-congestion device, including a transmission mechanism and a clearing blade C. The clearing blade C is a rotary tillage blade or one of the above-mentioned clearing blades C. The two ends of the transmission mechanism are respectively linked to the power source and the clearing blade C, and are used to transmit the power of the power source to the clearing blade C for rotation.

[0046] The transmission mechanism includes a driving shaft A2, a chain box A4, and a driven shaft A3. The driving shaft and the driven shaft A3 are linked by the chain box A4. The driving shaft A2 is hinged to the frame D through a bearing seat. The cleaning blade C is sleeved on one or both ends of the driven shaft A3. After the key is placed in the keyway C9, the fixing nut is tightened on the driven shaft A3, completing the connection between the cleaning blade C and the driven shaft A3. The axis C3 of the cleaning blade C is parallel and / or perpendicular to the forward direction of the sowing leg F1. Two cleaning blades C are set on both sides of the chain box A4 to increase the debris removal effect. When the axis C3 of the two cleaning blades C on both sides of the chain box A4 is parallel to the forward direction of the sowing leg F1, the debris is thrown to the left and right sides of the sowing leg F1. When the axis C3 of the cleaning blade C is perpendicular to the forward direction of the sowing leg F1, the debris is thrown to the rear of the sowing leg F1 to prevent debris from accumulating at the sowing leg F1.

[0047] When the clearing blade C is a rotary tillage blade, multiple rotary tillage blades are connected to the driven rotating shaft A3 through the rotary tillage blade holder, or directly welded to the driven rotating shaft A3 (this connection method is the same as the connection method of the rotary tillage blades in the rotary tiller, and will not be described in detail here, nor is it shown in the attached diagram).

[0048] The chain box A4 is equipped with a telescopic rod C4 on the side near the clearing blade C, which is used to adjust the height of the clearing blade C so that the clearing blade C just touches or does not touch the ground when rotating. One end of the telescopic rod C4 is hinged to the chain box A4, and the other end of the telescopic rod C4 is hinged to the mounting seat C5 on the frame D. The telescopic rod C4 can adjust the height of the clearing blade C according to different sowing depths, so that the wing plate C6 just touches or does not touch the ground when rotating. This ensures that while removing debris from the ground, especially larger debris, it minimizes damage to the soil layer. Since the fertilization, anti-clogging device and sowing are on the same axis C3, it prevents the wing plate C6 from forming trenches on the ground, which would not only dig up fertilizer but also affect subsequent sowing and covering.

[0049] To better solve the aforementioned technical problems, the above-mentioned anti-congestion device for the seeding leg is combined with the existing triangular seedling fixing and no-till seeder body with fertilization function, forming another technical solution of this application. This technical solution is as follows: Figures 1-8 A triangular seedling fixed no-till seeder includes a seeder body and an anti-congestion device. The seeder 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 drive shaft A2 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 driven shaft A3 and the clearing blade C to rotate through the drive shaft A2 and the chain box A3 (at this time, the axis C3 of the clearing blade C is perpendicular to the forward direction of the sowing leg F1. When it is necessary to make the axis C3 of the clearing blade C parallel to the forward direction of the sowing leg F1, it is only necessary to add a commutator between the clearing blade C and the chain box A3). At the same time, when the height of the clearing blade C is adjusted, the chain box A3 can rotate around the 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] 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.

[0053] 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 clearing blade C 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 clearing blade C and the ground is relatively stable, ensuring the stability of clearing debris and preventing the clearing blade C from contacting the soil too much and damaging the soil.

[0054] When the axis C3 of the clearing blade C is perpendicular to the forward direction of the sowing leg F1, the rotation path of the wing plate C6 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 clearing blade C to throw away the debris, with good passability.

[0055] 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.

[0056] 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 clearing blade C 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.

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.
