Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to a rice paddy green manure sowing device. Background Technology

[0002] Green manure sowing in paddy fields is an important agricultural technique. Leguminous green manure crops such as milkvetch, vetch, and arrowroot have nitrogen-fixing capabilities. Their decomposition releases large amounts of nitrogen, helping to maintain the nitrogen cycle in farmland. Green manure also increases soil organic matter, improves soil structure, and makes the soil looser. Long-term planting of green manure can increase soil organic carbon and total nitrogen content, with an average annual increase of 0.404 g / kg and 0.048 g / kg respectively compared to fallow fields. Moreover, returning green manure to the field can significantly reduce the use of chemical fertilizers.

[0003] In some areas where green manure is sown late, it is sown after the rice harvest. However, when rice is harvested, green manure is usually sown in the paddy fields before the rice is harvested. When rice straw is returned to the field to cover the surface, the green manure seeds, such as milkvetch, vetch, and arrowhead pea, will remain on the straw and cannot reach the ground, thus affecting the germination and emergence of the green manure seeds. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a rice paddy green manure sowing device that ensures the green manure seeds land on the ground, which is beneficial for seed germination, increases the seedling emergence rate, and guarantees the subsequent growth of the green manure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rice paddy green manure sowing device includes a vehicle body. A sowing mechanism is provided at one end of the vehicle body near the direction of travel. The sowing mechanism includes a fixed plate and a storage box. The fixed plate is fixedly connected to the vehicle body, and the storage box is fixedly mounted on the fixed plate. A cavity is provided inside the fixed plate, and a plurality of sowing cylinders are evenly spaced inside the cavity. A feed inlet is provided on the side wall of one end of each sowing cylinder, and the feed inlet is connected to the storage box so that seeds in the storage box can enter the sowing cylinder through the feed inlet. A discharge outlet is provided on the side wall of the other end of each sowing cylinder, and a discharge pipe is provided at the discharge outlet. A spiral feeding rod is rotatably provided inside the sowing cylinder. The spiral feeding rod is driven by a first motor so that the seeds in the sowing cylinder can be discharged through the discharge outlet.

[0007] The vehicle body is equipped with a grass-turning mechanism at the end away from the direction of travel. The grass-turning mechanism includes a grass-turning cylinder, and multiple grass-turning rods are provided on the outer wall of the grass-turning cylinder. The grass-turning cylinder is connected to the vehicle body through a frame, and the grass-turning cylinder is driven to rotate by a second motor.

[0008] Furthermore, a drive shaft is provided at one end of the seeding cylinder, the drive shaft passes through the seeding cylinder and is fixedly connected to the spiral feeding rod, and a first bevel gear is fixedly provided at the end of the drive shaft away from the spiral feeding rod.

[0009] A drive shaft is rotatably disposed within the cavity, and a second bevel gear that meshes with the first bevel gear is fixedly disposed on the drive shaft. The first motor is fixed in the cavity and is connected to the drive shaft for transmission.

[0010] Furthermore, the feed inlet is provided with a feed pipe, and the two ends of the feed pipe are respectively connected to the storage box and the seeding cylinder; the feed pipe is provided with an electromagnetic switch valve to control the opening and closing of the feed pipe.

[0011] Furthermore, the frame includes two arms, which are arranged opposite each other and connected by a connecting plate. A rotating shaft is fixedly installed at each end of the grass-turning cylinder, and the rotating shaft is rotatably connected to one end of the corresponding arm. One arm has a cavity, and the corresponding rotating shaft is embedded in the cavity and fixedly fitted with a first toothed disc. A second toothed disc is installed in the cavity and rotatably connected to the arm. The second toothed disc is driven by the first toothed disc via a chain. A second motor is fixedly connected to the outer wall of the arm, and the output shaft of the second motor is driven by the second toothed disc.

[0012] Furthermore, a protective cover is fixedly installed between the two arms, the protective cover being located at the end of the arm away from the vehicle body, and the protective cover covering the top of the grass-turning tube.

[0013] Furthermore, the end of the arm away from the grass-turning tube is rotatably connected to the vehicle body, and the connecting plate is provided with a hydraulic telescopic rod. One end of the hydraulic telescopic rod is rotatably connected to the connecting plate, and the other end is rotatably connected to the vehicle body to control the height of the grass-turning tube.

[0014] The beneficial effects of this utility model are:

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please also see Figures 1 to 5 The preferred embodiment of the rice paddy green manure sowing device of this utility model includes a vehicle body 1, which is driven by tracks 11.

[0027] A sowing mechanism is provided at one end of the vehicle body 1 near the direction of travel. The sowing mechanism includes a fixed plate 2 and a storage box 21. The fixed plate 2 is fixedly connected to the vehicle body 1. The storage box 21 is fixedly mounted on the fixed plate 2. A cavity 201 is provided inside the fixed plate 2. Several sowing cylinders 22 are evenly spaced inside the cavity 201. A feed inlet 221 is provided on the side wall of one end of the sowing cylinder 22. The feed inlet 221 is connected to the storage box 21 so that the seeds in the storage box 21 can enter the sowing cylinder 22 through the feed inlet 221. A discharge outlet 222 is provided on the side wall of the other end of the sowing cylinder 22. A discharge pipe 223 is provided on the discharge outlet 222. A spiral feeding rod 23 is rotatably provided inside the sowing cylinder 22. The spiral feeding rod 23 is driven by a first motor 231 so that the seeds in the sowing cylinder 22 can be discharged through the discharge outlet 222. In this embodiment, the end of the discharge pipe 223 away from the discharge port 222 extends out of the cavity 201, and the end of the storage box 21 away from the fixing plate 2 is provided with an opening for putting in green manure seeds. The end of the storage box 21 near the fixing plate 2 is provided with an inclined surface to guide the green manure seeds into the feed port 221.

[0028] The green manure seeds in the storage box 21 enter the seeding cylinder 22 through the feed inlet 221. Driven by the first motor 231, the screw feeder 23 rotates, allowing the green manure seeds in the seeding cylinder 22 to be discharged through the discharge outlet 222. At the same time, under the action of the vehicle body 1, the green manure seeds can be evenly scattered on the paddy field.

[0029] like Figure 2 and Figure 3 As shown, a drive shaft 224 is provided at one end of the seeding cylinder 22. The drive shaft 224 passes through the seeding cylinder 22 and is fixedly connected to the screw feeding rod 23. A first bevel gear 51 is fixedly provided at the end of the drive shaft 224 away from the screw feeding rod 23.

[0030] A drive shaft 5 is rotatably mounted inside the cavity 201. A second bevel gear 52, meshing with a first bevel gear 51, is fixedly mounted on the drive shaft 5. A first motor 231 is fixed in the cavity 201 and connected to the drive shaft 5 for transmission. Under the drive of the first motor 231, the drive shaft 5 rotates, driving the second bevel gear 52 to rotate. This causes the first bevel gear 51 to drive the screw feed rod 23 to rotate via the transmission shaft 224, thus uniformly discharging green manure seeds outside the sowing cylinder 22. By controlling the rotation of the first motor 231, the seed discharge speed can be adjusted, thereby controlling the growth density of the green manure. In this embodiment, the meshing of the first bevel gear 51 with the corresponding second bevel gear 52 on the drive shaft 5 allows for unified driving of all screw feed rods 23 by a single first motor 231, reducing costs. The first motor 231 is equipped with a first gear 531, and the drive shaft 5 is equipped with a second gear 532 meshing with the first gear 531, enabling the first motor 231 to drive the drive shaft 5.

[0031] like Figure 2 As shown, the feed inlet 221 is equipped with a feed pipe 225, with both ends of the feed pipe 225 being electrically connected to the storage box 21 and the seeding cylinder 22, respectively. The feed pipe 225 is equipped with an electromagnetic switch valve 226 to control the opening and closing of the feed pipe 225. Controlling the electromagnetic switch valve 226 to close the feed pipe 225 prevents green manure seeds from entering the seeding cylinder 22, thus allowing for control of the sowing spacing as needed.

[0032] like Figure 1 As shown, a straw-turning mechanism is provided at the end of the vehicle body 1 away from the direction of travel. The straw-turning mechanism includes a straw-turning cylinder 3, and multiple straw-turning rods 31 are provided on the outer wall of the straw-turning cylinder 3. The straw-turning cylinder 3 is connected to the vehicle body 1 through a frame 4, and the straw-turning cylinder 3 is driven to rotate by a second motor 32. In this embodiment, the straw-turning rods 31 are bent at the end away from the straw-turning cylinder 3, and the bending direction is towards the rotation direction of the straw-turning cylinder 3, so as to turn over the straw.

[0033] After the green manure seeds are evenly scattered on the paddy field, the seeding cylinder 22 at the rear of the vehicle body 1 rotates under the drive of the second motor 32, causing the straw-turning rod 31 to turn and throw the straw up, thereby shaking the green manure seeds onto the paddy field. This ensures that the green manure seeds land on the ground. At the same time, the straw covers the green manure seeds, which helps to protect them, keep them warm and moist, and promotes germination, thereby increasing the emergence rate of the green manure and ensuring its growth in the later stages.

[0034] like Figure 4 and Figure 5 As shown, the frame 4 includes two arms 41, which are arranged opposite each other and connected by a connecting plate 42. In this embodiment, there are two connecting plates 42, which are located in the middle of the arms 41.

[0035] The turning tube 3 has a rotating shaft 32 fixedly installed at both ends. The rotating shaft 32 is rotatably connected to one end of the corresponding arm body 41. One arm body 41 is provided with a cavity 411. The corresponding rotating shaft 32 is embedded in the cavity 411 and a first toothed disc 51 is fixedly installed. A second toothed disc 52 is provided in the cavity 411 and is rotatably connected to the arm body 41. The second toothed disc 52 is connected to the first toothed disc 51 through a chain 5. The second motor 32 is fixedly connected to the outer wall of the arm body 41, and the output shaft of the second motor 32 is connected to the second toothed disc 52.

[0036] Driven by the second motor 32, the second toothed disc 52 drives the first toothed disc 51 to rotate via the chain 5, causing the straw-turning cylinder 3 to rotate accordingly. During the movement of the vehicle body 1, the straw-turning rod 31 can flip and throw the straw.

[0037] like Figure 1 As shown, a protective cover 6 is fixedly installed between the two arm bodies 41. The protective cover 6 is located at the end of the arm body 41 away from the vehicle body 1, and it covers the top of the grass-turning cylinder 3. The protective cover 6 can shield the discarded grass clippings, preventing them from damaging the second motor 32. In this embodiment, the protective cover 6 has an arc-shaped structure with an angle of 110°-130°.

[0038] The end of the arm 41 furthest from the grass-turning cylinder 3 is rotatably connected to the vehicle body 1. A hydraulic telescopic rod 7 is provided on the connecting plate 42, with one end rotatably connected to the connecting plate 42 and the other end rotatably connected to the vehicle body 1 to control the height of the grass-turning cylinder 3. In this embodiment, the vehicle body 1 is provided with a support frame 12, with one end of the hydraulic telescopic rod 7 rotatably connected to the support frame 12 and the other end rotatably connected to the middle of the connecting plate 42.

[0039] By controlling the extension of the hydraulic telescopic rod 7, the straw-turning tube 3 can move closer to the ground, thereby enabling the straw-turning pole 31 to turn over the roots of the straw and flip and throw it up. By controlling the shortening of the hydraulic telescopic rod 7, the straw-turning tube 3 can move away from the ground, preventing the straw-turning pole 31 from hitting the road surface when the vehicle body 1 is driving normally.

[0040] In this embodiment, when the green manure sowing device for paddy fields is in operation, the green manure seeds in the storage box 21 enter the sowing cylinder 22 through the feed inlet 221. Driven by the first motor 231, the screw feeder 23 rotates, allowing the green manure seeds in the sowing cylinder 22 to be discharged through the discharge outlet 222. At the same time, under the action of the vehicle body 1, the green manure seeds can be evenly scattered on the paddy field. The sowing cylinder 22 behind the vehicle body 1 rotates under the drive of the second motor 32, causing the straw turning rod 31 to turn and throw the straw up, thereby shaking the green manure seeds onto the paddy field, ensuring that the green manure seeds land on the ground.
