Description

Technical Field

[0001] This utility model relates to the field of seeder technology, specifically to a seeder soil covering mechanism and a triangular seeder. Background Technology

[0002] When planting crops in dryland farming areas, the ground needs to be rotary tilled and fertilized, then covered with mulch to retain moisture and fertilizer. The mulch roll should be pressed down with soil before finally sowing in holes. This process aims to retain moisture and fertilizer for the seeds and reduce the impact of drought.

[0003] A mulching seeder is an agricultural machine that integrates multiple functions such as ditching, fertilizing, sowing, mulching, and soil covering. It is widely used in the planting of crops such as cotton, corn, millet, and rapeseed. For example, Chinese patent document CN103597936A discloses a multi-functional fertilizing, tape-laying, and mulching seeder, which includes a frame, a fertilizing device, a tape-laying device, a mulching device, and a sowing device. The fertilizing device's fertilizing box consists of a base fertilizer box and a top fertilizer box. The base fertilizer box is equipped with a deep fertilizer discharge device, which includes a discharge chamber and a mixer. The upper part of the discharge chamber is connected to the base fertilizer box, and the lower part of the discharge chamber is equipped with a discharge port and a fertilizer control plate.

[0004] Although the seeder has a large fertilizer discharge capacity and applies fertilizer evenly without causing blockages, it cannot adjust the amount of soil covering the edges of the laid mulch film, thus affecting the air permeability of the mulch film edges. Utility Model Content

[0005] The purpose of this utility model is to provide a soil covering mechanism for a seeder and a triangular seeder, which solves the problem in the prior art that the seeder cannot adjust the amount of soil covering the edge of the laid mulch film, thereby adjusting the air permeability of the mulch film edge.

[0006] To achieve the above objectives, this utility model provides a soil covering mechanism for a seeder, including at least one soil transport device. The soil transport device includes a soil transport box, which is provided with a soil inlet, a soil outlet, and a conveying component. The conveying component transports soil from the soil inlet to the soil outlet. The soil outlet is inclined towards the edge of the mulch film and is provided with a soil throwing plate. The soil transport box is provided with an adjusting device, which is connected to the soil throwing plate and adjusts the soil throwing angle of the soil throwing plate.

[0007] Furthermore, the adjusting device includes a drive rod and a transmission rod. One end of the transmission rod is rotatably connected to the end of the drive rod, and the other end of the transmission rod is fixedly connected to the soil-throwing plate. The transmission rod is rotatably connected to the soil-carrying box via a rotating pin, and the drive rod drives the transmission rod to rotate around the rotating pin.

[0008] Furthermore, the drive rod is threaded, passes through the soil transport box, and is threadedly connected to the soil transport box; the end of the drive rod is connected to the transmission rod through a bearing, and the end of the transmission rod connected to the soil throwing plate is connected to multiple support rods, which are connected to the bottom of the soil throwing plate and extend in the length or width direction of the soil throwing plate.

[0009] Furthermore, the soil transport box has a soil covering opening on the side facing the ground, and the projection of the soil covering opening on the mulch film is located between the two edges of the mulch film.

[0010] Furthermore, a film covering device is provided below the soil covering opening of the soil transport box. The film covering device includes a film covering shaft and a film pressing roller. The film covering shaft is used to install the rolled-up mulch film, and the film pressing roller is used to press the unfolded mulch film tightly.

[0011] Furthermore, the axial end of the pressure roller extends beyond the soil discharge port; the covering shaft is a split structure, including two covering half shafts, which are distributed on both sides of the soil transport box.

[0012] Furthermore, a soil-turning plate is installed near the soil inlet of the soil transport box, which turns the soil to the soil inlet.

[0013] Furthermore, the conveying assembly includes a driving sprocket, a driven sprocket, and a conveying chain, the conveying chain connecting the driving sprocket and the driven sprocket; a plurality of conveying baffles are connected to the side of the conveying chain that meshes with the driving sprocket.

[0014] This utility model also provides a triangular seeder, including a frame, on which ground wheels, the aforementioned soil covering mechanism and sowing mechanism are installed sequentially in front and behind along the direction of travel of the seeder. The ground wheels are connected to the soil covering mechanism through a transmission mechanism, driving the conveying component to operate.

[0015] Furthermore, the frame is connected to a ridging device, which is located in front of the mulching device.

[0016] Compared with existing known technologies, the technical solution provided by this utility model has the following beneficial effects:

[0017] This utility model discloses a soil-covering mechanism for a seeder. A soil-carrying box transports soil to a discharge port, which is angled towards the edge of the mulch film. This allows the soil to be discharged to the edge of the mulch film, covering it and maintaining its stability to prevent it from being blown away by the wind. Covering the edge of the mulch film with soil also seals the gaps between the mulch film and the soil, reducing moisture loss. The discharge port is equipped with a soil-throwing plate connected to an adjustment device. This device allows adjustment of the throwing angle of the soil-throwing plate. By changing the throwing angle, the landing point of the soil thrown from the discharge port can be changed. Based on the distance of the landing point from the edge of the mulch film, the amount of soil landing on the edge can be adjusted, thereby adjusting the soil's permeability to the mulch film edge and the pressure on the mulch film to maintain its stability.

[0018] It is obvious that the elements or features described in the above individual embodiments can be used alone or in combination in other embodiments. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0028] Reference Figures 1-5 This application provides a triangular seeder, including a frame 200. Along the seeder's travel direction, the frame 200 is sequentially equipped with a ground wheel 210, a soil covering mechanism, and a seeding mechanism 300. The ground wheel 210 is connected to the soil covering mechanism via a transmission mechanism, and its rolling motion drives the soil covering mechanism and the seeding mechanism 300. The operation of the ground wheel 210 and the transmission mechanism reduces the need for a separate power source, thus meeting the power requirements of the soil covering mechanism and the seeding mechanism 300. The seeding mechanism 300 uses commercially available, mature mechanical components, which will not be described in detail here.

[0029] Drip irrigation under mulch film is a water-saving and high-yield cultivation technology that is currently being vigorously promoted. Multiple operations, including ditching, fertilization, laying the mulch film, covering with mulch, sowing, covering with soil, and compaction, can all be performed on a single seeder. In practice, after laying the mulch film on the raised beds, it is usually necessary to cover it with some soil.

[0030] like Figure 2 and Figure 3As shown, in some embodiments, the soil covering mechanism includes two soil transport devices 100, which are spaced apart and positioned close to the ground wheels 210 on both sides. Specifically, each soil transport device 100 includes a soil transport box 110, which has an inlet 120, a outlet 130, and a conveying assembly 140. The conveying assembly 140 transports soil from the inlet 120 to the outlet 130. The soil transport box 110 is inclined, with one end of the inlet 120 close to the ground and the other end of the outlet 130 higher than the inlet 120. The outlet 130 is inclined towards the edge of the mulch film, allowing soil to be discharged to the edge of the mulch film, covering it, maintaining its stability, and preventing it from being blown away by the wind. Furthermore, covering the edge of the mulch film with soil seals the gaps between the mulch film and the soil, reducing moisture loss. The soil discharge port 130 is equipped with a soil throwing plate 131, and the soil transport box 110 is equipped with an adjustment device 150. The adjustment device 150 is connected to the soil throwing plate 131 and adjusts the soil throwing angle of the soil throwing plate 131. By changing the soil throwing angle of the soil throwing plate 131, the landing point of the soil thrown from the soil discharge port 130 can be changed. According to the position of the landing point from the edge of the mulch film, the amount of soil landing on the edge of the mulch film can be adjusted, thereby adjusting the soil's permeability to the edge of the mulch film and the pressure on the mulch film to maintain the stability of the mulch film.

[0031] It should be noted that the soil covering mechanism can also be equipped with a soil transport device 100. The soil transport device 100 can be equipped with a soil discharge port 130 at each of the two sides of the mulch film, so as to meet the requirement that the soil transport device 100 throws soil to both sides to cover the edges of the mulch film.

[0032] Furthermore, such as Figure 4 As shown, the adjusting device 150 includes a drive rod 151 and a transmission rod 152. One end of the transmission rod 152 is rotatably connected to the end of the drive rod 151, and the other end of the transmission rod 152 is fixedly connected to the soil-throwing plate 131. The transmission rod 152 is rotatably connected to the soil-carrying box 110 via a rotating pin 153. The drive rod 151 drives the transmission rod 152 to rotate around the rotating pin 153. When the transmission rod 152 rotates around the rotating pin 153, the soil-throwing plate 131 rotates with the transmission rod 152 around the rotating pin 153, thereby changing the angle of the soil-throwing plate 131 relative to the ground.

[0033] To ensure the limiting stability of the drive rod 151, in some embodiments, the drive rod 151 is threaded, passes through the soil transport box 110, and is threadedly connected to the soil transport box 110. A threaded seat 155 is fixedly installed on the inner wall of the soil transport box 110, and the drive rod 151 passes through the box wall of the soil transport box 110 and is threadedly connected to the threaded seat 155. This increases the connection tightness between the drive rod 151 and the threaded seat 155, improves the connection stability, and maintains good self-locking between the drive rod 151 and the soil transport box 110. The end of the drive rod 151 is connected to the transmission rod 152 through a bearing. When the drive rod 151 rotates, the drive rod 151 generates axial displacement due to the threaded structure, thereby pushing the transmission rod 152 to deflect around the rotating pin 153. The bearing structure ensures that the end of the drive rod 151 rotates relative to the transmission rod 152. Multiple support rods 154 are connected to one end of the transmission rod 152 that connects to the soil-throwing plate 131. The support rods 154 are connected to the bottom of the soil-throwing plate 131 and extend along the length or width of the soil-throwing plate 131. The support rods 154 can increase the connection area between the transmission rod 152 and the soil-throwing plate 131, thereby improving the connection stability with the soil-throwing plate 131.

[0034] When covering mulch film with soil, in addition to covering the edges of the film, sometimes it is also necessary to cover the area near the center with soil. In some embodiments, such as... Figure 3 As shown, the soil transport box 110 has a soil covering opening 111 on the side facing the ground. The projection of the soil covering opening 111 on the mulch film is located between the two edges of the mulch film. When the soil transport box 110 transports soil to the soil discharge opening 130, some soil can leak through the soil covering opening 111 to cover the middle part of the mulch film. The soil covering the middle part of the mulch film increases the stability of the mulch film and also allows some soil to be reserved for the sowing position, thereby improving the growth rate of the seeds.

[0035] It is understandable that the coating process is inseparable from related structures, such as in some embodiments. Figure 2 As shown, a film covering device 170 is provided below the soil covering opening 111 of the soil transport box 110. The film covering device 170 includes a film covering shaft 171 and a film pressing roller 172. The film covering shaft 171 is used to install the rolled mulch film, and the film pressing roller 172 is used to press the unfolded mulch film. The width of the mulch film is generally greater than the distance between the soil discharge openings 130 of the soil transport devices 100 on both sides, so that the soil can fall near the edge of the mulch film. The axial end of the film pressing roller 172 extends beyond the soil discharge opening 130, so that the film pressing roller 172 has sufficient length to press the mulch film with a certain width. The film covering shaft 171 is a split structure, including two film covering half shafts, which are distributed on both sides of the soil transport box 110. This split structure facilitates the installation of rolled mulch film.

[0036] To improve the soil transport efficiency of the soil transport device 100, such as Figure 2 As shown, a soil-turning plate 160 is installed near the soil inlet 120 of the soil transport box 110. The soil-turning plate 160 turns the soil to the soil inlet 120. The soil accumulates at the soil inlet 120, and the conveying assembly 140 transports the accumulated soil from the soil inlet 120 to the soil outlet 130. Specifically, when the ground wheel 210 rotates, it drives the conveying assembly 140 to operate, such as... Figure 5 As shown, the conveying assembly 140 includes a drive sprocket 141, a driven sprocket 142, and a conveying chain 143. The conveying chain 143 connects the drive sprocket 141 and the driven sprocket 142. The drive sprocket 141 receives power from the ground wheel 210 through a transmission assembly and transmits the power to the driven sprocket 142 through the conveying chain 143. The conveying chain 143 rotates around the drive sprocket 141 and the driven sprocket 142. Multiple conveying baffles 144 are connected to the side of the conveying chain 143 that meshes with the drive sprocket 141. The conveying baffles 144 rotate with the conveying chain 143. When the conveying baffles 144 pass the soil inlet 120, they scoop up the soil, which is then conveyed towards the soil outlet 130. When the conveying baffles 144 pass the soil outlet 130, the soil falls and slides onto the soil throwing plate 131, where it is thrown out.

[0037] It should be noted that the mulch film is usually applied to the ridges in the field. In some embodiments, such as... Figure 1 As shown, the frame 200 is connected to a ridging device 220, which is a disc-shaped structure and is connected to the frame 200 via a connecting rod. The ridging device 220 is in contact with the ground and turns the soil into ridges when the seeder is running. The ridging device 220 is located in front of the mulching device 170. Here, "front" refers to the front of the seeder in the direction of travel, which can produce the effect of ridging first and then mulching.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
