Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to a multi-ridge furrow sowing and covering machine. Background Technology

[0002] The multi-row seeding and covering machine is a modern agricultural machine that integrates seeding, furrowing, and covering functions, suitable for planting various crops such as corn, soybeans, and vegetables. This machine can complete multiple rows in one operation. The matching furrowing device can form standard furrows as needed, while the covering component evenly covers the seeds, reducing manual intervention. The equipment is compatible with different tractors, increasing operating efficiency by 3-5 times compared to traditional methods. It also ensures high seeding consistency, promoting uniform crop emergence, and is widely used in large-scale planting bases, helping to improve the quality and efficiency of agricultural production.

[0003] Currently, multi-furrow seeding and covering machines have separate furrowing and covering components, with seeding occurring between them. After furrowing, soil fall back down significantly, with some soil entering the furrows. Seeds that were initially planted then fall onto this fallen soil, leading to shallow planting and insufficient subsequent covering, resulting in exposed seeds. Therefore, we propose a multi-furrow seeding and covering machine. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a multi-ridge furrow sowing and covering machine to solve the technical problems of serious soil fall-off after furrowing and poor sowing effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-row furrow sowing and covering machine, including a frame and a sowing mechanism and a furrowing and covering mechanism installed on the frame. The frame includes a beam frame, and a plurality of second mounting frames are equidistantly arranged on the beam frame. The sowing mechanism includes a sowing box located at the rear end of the second mounting frames. The sowing box is provided with a box cover. A baffle plate is provided inside the sowing box. A discharge pipe is provided at the lower end of the sowing box. A discharge pipe is provided at the lower end of the discharge pipe. A connecting rod is provided at the lower end of the second mounting frame. A third mounting frame is provided at the end of the connecting rod. The furrowing and covering mechanism includes a pressing wheel arranged between the third mounting frames and a furrowing and covering plate arranged at the lower end of the third mounting frame.

[0006] Preferably, a traction frame is installed at the middle position of the beam frame, and a first mounting frame is provided at both ends of the beam frame. A wheel axle is rotatably mounted on the first mounting frame, and a movable wheel is provided at the end of the wheel axle.

[0007] Preferably, a drive shaft is rotatably mounted between the first mounting brackets, the drive shaft passes through the discharge pipe, and a seeding wheel is mounted on the drive shaft inside the discharge pipe, the seeding wheel having a seed groove.

[0008] Preferably, a drive sprocket is mounted on the axle, a driven sprocket is mounted on the drive shaft, and a transmission chain is provided between the drive sprocket and the driven sprocket.

[0009] Preferably, the trenching and covering plate includes, from front to back, a trenching section, a trench widening section, an entry section, and a covering section. The trenching section is a sharp, plate-like structure. The trench widening section is a plate-like structure that opens outward and is symmetrically distributed. An installation section is provided at the upper end of the trench widening section. The installation section is connected to a third mounting frame by bolts. The front part of the entry section opens outward and bends into an arc shape. An entry port is provided at the front part of the entry section. The rear part of the entry section bends inward into an arc shape. The height of the covering section gradually decreases along its long axis. The covering section is arranged in an inverted U-shape.

[0010] Preferably, the third mounting bracket is provided with a guide pipe, the lower end of which is located between the widened grooves, and the end of the discharge pipe extends into the guide pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a trenching and covering plate structure. The trenching part of the trenching and covering plate first forms an initial furrow, and the widening part pushes the soil outward and maintains the shape of the furrow, effectively preventing soil from re-entering the furrow and ensuring that the seeds can be sown into the furrow at the preset depth. The seeds are accurately transported to the furrow between the widening parts through the guide pipe. Combined with the stability of the furrow maintained by the trenching and covering plate, the accuracy and consistency of the seed sowing position are guaranteed, avoiding sowing too shallow or seed exposure due to soil falling back, and significantly improving the sowing effect. The covering part is inverted U-shaped and gradually decreases in height, which can stably cover the seeds on both sides. Combined with the compaction effect of the subsequent rolling roller, the seeds are in close contact with the soil, providing a good environment for seed germination and solving the problem of serious soil falling back after trenching and poor sowing effect.

[0012] 2. This utility model also designs a seeding box structure. The seeding mechanism realizes the linkage between the drive shaft and the moving wheel through the chain drive. The seeding wheel rotates synchronously with the movement of the equipment. Its seed trough can carry seeds quantitatively and drop them accurately. With the guiding effect of the baffle plate, it ensures that the seeding amount per unit area is uniform and stable. The design of the feeding pipe and the guide pipe can directly transport the seeds to the center position of the furrow between the furrows, avoid seed deviation, and ensure that the seeding position of each ridge is consistent when multiple ridges are operated, laying the foundation for the uniformity of crop growth in the later stage.

Detailed Implementation

[0015] like Figures 1 to 6 As shown, this utility model relates to a multi-row sowing and covering machine, which includes a frame 100 and a sowing mechanism 200 and a furrowing and covering mechanism 300 installed on the frame 100. The frame 100 includes a beam frame 101, on which a plurality of second mounting frames 106 are equidistantly arranged. The sowing mechanism 200 includes a sowing box 201 located at the rear end of the second mounting frames 106. The sowing box 201 is provided with a box cover 202. A baffle plate 205 is provided inside the sowing box 201. A discharge pipe 203 is provided at the lower end of the sowing box 201. A feeding pipe 206 is provided at the lower end of the discharge pipe 203. A connecting rod 108 is provided at the lower end of the second mounting frames 106. A third mounting frame 109 is provided at the end of the connecting rod 108. The furrowing and covering mechanism 300 includes a pressing wheel 302 arranged between the third mounting frames 109 and a furrowing and covering plate 301 arranged at the lower end of the third mounting frames 109. This invention uses the widening section 3012 of the trenching and covering plate 301 to prevent soil from falling back after trenching, ensuring that the seeds are sown at the preset depth. The seeds are accurately placed into the trench through the guide pipe 207, and the covering section 3016 and the pressing wheel 302 work together to achieve uniform soil covering and compaction, solving the problems of shallow sowing and exposed seeds. In addition, the sowing wheel 204 sows in a quantitative manner, improving the sowing effect and consistency.

[0016] Specifically, a traction frame 107 is installed at the middle position of the beam frame 101, and a first mounting frame 102 is provided at both ends of the beam frame 101. A wheel axle 103 is rotatably mounted on the first mounting frame 102, and a movable wheel 104 is provided at the end of the wheel axle 103. When the seeding and covering machine is towed by an agricultural tractor, the rotation of the movable wheel 104 can cause the wheel axle 103 to rotate, thereby causing the drive sprocket 105 to rotate.

[0017] Furthermore, a drive shaft 208 is rotatably mounted between the first mounting brackets 102. The drive shaft 208 passes through the discharge pipe 203, and a seeding wheel 204 is mounted on the drive shaft 208 inside the discharge pipe 203. The seeding wheel 204 has a seed groove. When the drive shaft 208 rotates, it causes the seeding wheel 204 to rotate, and the seeds in the seed box 201 enter the seed groove from above the seeding wheel 204. When the seed groove of the seeding wheel 204 rotates to the lower position, the seeds in the seed groove fall out, thereby discharging the seeds from the discharge pipe 206.

[0018] It is worth noting that a drive sprocket 105 is mounted on the axle 103, and a driven sprocket 209 is mounted on the drive shaft 208. A transmission chain is provided between the drive sprocket 105 and the driven sprocket 209. When the drive sprocket 105 rotates, the driven sprocket 209 can rotate under the action of the transmission chain, thereby causing the drive shaft 208 to rotate.

[0019] It is worth mentioning that the trenching and covering plate 301 includes, from front to back, a trenching section 3011, a trench widening section 3012, an entry section 3014, and a covering section 3016. The trenching section 3011 is a sharp plate-like structure, the trench widening section 3012 is a plate-like structure that opens outward and is symmetrically distributed, and the upper end of the trench widening section 3012 is provided with an installation section 3013. The installation section 3013 is connected to the third mounting bracket 109 by bolts. The front part of the entry section 3014 opens outward and bends into an arc shape. The front part of the entry section 3014 has an entry port 3015. The rear part of the entry section 3014 bends inward into an arc shape. The height of the covering section 3016 gradually decreases along the long axis direction, and the covering section 3016 is arranged in an inverted U-shape. When the device is moved by a tractor, the furrowing and covering plate 301 is located in the soil. The furrowing part 3011 can open the soil. Under the action of the furrow widening part 3012, the furrowed soil can be pushed to both sides, which can widen the furrow and prevent soil from re-entering the furrow. At this time, the sowing mechanism 200 sows the seeds into the furrow. As the device continues to move, the soil on both sides will enter the space between the inlet 3014 from the inlet 3015. As the height of the covering part 3016 gradually decreases, the soil located in the furrowing and covering plate 301 can be re-filled into the furrow. The covering part 3016 can initially flatten the soil, and then the compaction wheel 302 can compact the soil again.

[0020] It is worth noting that a guide pipe 207 is provided on the third mounting frame 109. The lower end of the guide pipe 207 is located between the furrow widening sections 3012, and the end of the discharge pipe 206 extends into the guide pipe 207. When the equipment moves, the seeds sown by the seeding mechanism 200 are discharged from the discharge pipe 206 into the guide pipe 207. The seeds can enter the furrow widening sections 3012 of the furrow covering plate 301 through the guide pipe 207, thereby ensuring that the seeds are accurately placed into the furrows.

[0021] Working Principle: This embodiment provides a multi-ridge furrow sowing and soil covering integrated machine. Before operation, the cover 202 of the sowing box 201 needs to be opened, and the seeds to be sown are poured into the sowing box 201. The baffle 205 inside the sowing box 201 can block and guide the seeds to a certain extent, preventing excessive accumulation or random movement of the seeds in the box, and ensuring that the seeds can move orderly to the discharge pipe 203. During operation, the equipment is connected to an agricultural tractor through the traction frame 107 on the beam frame 101. The tractor pulls the equipment forward. At this time, the moving wheels 104 at both ends of the equipment are in contact with the ground and rotate with the movement of the equipment. The rotation of the moving wheels 104 drives the wheel axle 103 to rotate synchronously, and the drive sprocket 105 on the wheel axle 103 also rotates accordingly. Since the driving sprocket 105 and the driven sprocket 209 on the drive shaft 208 are connected by a transmission chain, the rotation of the driving sprocket 105 drives the driven sprocket 209 to rotate via the chain drive, which in turn causes the drive shaft 208 to rotate. The drive shaft 208 passes through the discharge pipe 203, and its rotation drives the sowing wheel 204 installed in the discharge pipe 203 to rotate synchronously. The seeds in the sowing box 201 move downward under the action of gravity and enter the seed groove on the sowing wheel 204. As the sowing wheel 204 continues to rotate, when the seed groove rotates to the bottom, the seeds in the groove will fall due to gravity and enter the discharge pipe 206 through the discharge pipe 203. The end of the discharge pipe 206 extends into the guide pipe 207, and the seeds are accurately placed through the guide pipe 207. The soil is conveyed into the furrows between the furrow widening sections 3012 of the furrowing and covering plate 301. During the equipment's forward movement, the furrowing and covering plate 301 remains in contact with and penetrates the soil. Its front furrowing section 3011, a sharp, plate-like structure, first cuts into the soil to create initial furrows. Next, the furrow widening section 3012 comes into play. This section, a symmetrically distributed, outward-opening plate-like structure, pushes the furrowed soil to both sides, widening the furrows and effectively preventing the pushed-out soil from falling back into the furrows, creating stable space for subsequent sowing. After the seeds are sown into the furrows, the equipment continues to move forward, and the entry section 3014 of the furrowing and covering plate 301 begins to work. The front of the entry section 3014 opens and bends outward. The inlet 3015, which is arc-shaped, guides the soil pushed aside on both sides into the space between the inlet sections 3014. The rear part of the inlet section 3014 curves inward in an arc shape, which can gather the soil into the furrow. Then, the covering section 3016 plays its role. Its height gradually decreases along the long axis and is set in an inverted U-shape. During the movement of the equipment, it will gradually cover the seeds with the gathered soil, completing the covering operation. Finally, the pressing wheel 302 between the third mounting frame 109 comes into contact with the soil after covering. As the equipment moves forward, the pressing wheel 302 rolls and presses the soil covering the seeds, so that the soil and seeds are in close contact, which is conducive to seed germination and growth, and also reduces soil moisture evaporation.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations.
