Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, and specifically relates to a device for scallion seedling raising and sowing. Background Art

[0002] In modern agriculture, scallions, as an important cash crop, the efficiency and quality of the seedling raising and sowing process directly affect the growth and yield of the crops. However, there is still a lack of special equipment for scallion seedling raising and sowing in the current market, and most equipment still stays at the level of general sowers. These traditional equipment have multiple problems in design, which limit their application effects in the scallion seedling raising and sowing process.

[0003] Firstly, the design of existing equipment often has a low degree of integration. Most sowing equipment can only complete the functions of sowing or soil application separately, lacking the ability to integrate multiple steps such as sowing and soil application into one system. This separated functional design leads to a cumbersome operation process, low efficiency, requires multiple adjustments and manual intervention, increasing the labor intensity and operation difficulty.

[0004] Secondly, there is no effective linkage mechanism between the adjustment of the sowing speed and the traveling speed of the traditional sowing equipment. This design defect makes it difficult to ensure the uniformity of seed sowing during the operation of the equipment. The change in the traveling speed of the equipment directly affects the sowing speed and sowing density. However, existing equipment often does not have the function of automatically adjusting the sowing speed according to the traveling speed, resulting in uneven sowing and affecting the growth of scallions.

[0005] In addition, the traditional sowing equipment still sows seeds when performing a reverse operation, and this design defect causes the problem of repeated sowing of seeds. Repeated sowing not only leads to waste of seed resources, but also affects the normal growth of seeds and reduces the overall effect of seedling raising. This problem is particularly prominent in actual use, affecting the economy and operation convenience of the equipment. Content of the Utility Model

[0006] Aiming at the above deficiencies existing in the prior art, the purpose of the utility model is to provide a high-efficiency, precise and easy-to-operate scallion seedling raising and sowing device, which significantly improves the efficiency and quality of scallion seedling raising and has a wide application prospect.

[0009] It further includes a soil-opening shovel and a soil-covering shovel fixedly installed below the assembly frame. The soil-opening shovel and the soil-covering shovel are respectively arranged on the front and rear sides of the discharging connecting pipe.

[0010] It further includes a transmission mechanism assembled on the assembly frame. The transmission mechanism is in power connection with the connecting shaft and the cloth disk.

[0011] In some embodiments, to facilitate controlling the movement of the assembly frame between ridges and ensure the stable contact and operation of the rear wheels with the ground, a push handle is fixedly installed at the tail of the assembly frame.

[0012] In some embodiments, to ensure that the soil-opening shovel and the soil-covering shovel can be stably installed below the assembly frame and simultaneously realize the operations of slotting and soil covering, the following technical solutions are provided.

[0013] Both the soil-opening shovel and the soil-covering shovel are fixedly installed on an assembly plate. The assembly plate is fixedly installed at the bottom of the assembly frame. The soil-facing surface of the soil-opening shovel is set as a sharp-angle structure. The soil-facing surface of the soil-covering shovel is set as a wrapping structure. An arc-shaped groove is provided at the bottom of the soil-covering shovel.

[0014] In some embodiments, to ensure that the seed box can be stably installed on the assembly frame and the seed box is set higher than the seeding mechanism so that the green onion seeds stored in the seed box can be stably conveyed through the feeding connecting pipe, an assembly bracket is fixedly installed on the assembly frame. The seed box is fixedly installed on the assembly bracket. The feeding connecting pipe is arranged obliquely upward.

[0015] In some embodiments, to ensure that the transmission mechanism can be stably installed on the assembly frame and realize the stable transmission of the power of the rear wheels to the seeding mechanism, the following technical solutions are provided.

[0016] The transmission mechanism includes a transmission shaft, a rotating seat, and a ratchet mechanism. The transmission shaft and the rotating seat are both rotatably installed on the assembly frame and are coaxially arranged. The connecting shaft is in power connection with the transmission shaft. The cloth disk is in power connection with the rotating seat.

[0017] The ratchet mechanism includes an internal ratchet, a ratchet pawl, and a reed. The internal ratchet is arranged in the rotating seat. The ratchet pawl is rotatably mounted around the transmission shaft and remains engaged with the internal ratchet. The reed is assembled between the ratchet pawl and the transmission shaft.

[0018] In some of these embodiments, to ensure that the power of the rear wheel can be stably transmitted to the transmission shaft and the power of the rotating seat can be stably transmitted to the cloth disk, the following technical solutions are provided.

[0020] The beneficial effects of the present utility model are as follows:

[0021] 1. Highly integrated design: This solution realizes the integrated operation of the seedling raising and sowing process by integrating functions such as sowing, soil opening, and soil covering. Components such as a seed box, a sowing mechanism, a soil opening shovel, and a soil covering shovel are installed on the assembly frame. When traveling in the field, the sowing of scallion seeds and soil covering can be continuously completed, reducing the problems of multiple adjustments and manual intervention in traditional equipment, improving the operation efficiency, and reducing the labor intensity.

[0022] 2. Precise sowing control: This solution realizes the linkage adjustment of the sowing speed and the traveling speed of the equipment through the transmission mechanism. Specifically, components such as the ratchet mechanism and the chain drive device in the transmission mechanism ensure that the rotation speed of the cloth disk is synchronized with the traveling speed of the rear wheel, and the sowing speed can be dynamically adjusted according to the actual traveling speed, thereby ensuring the uniform distribution of scallion seeds in the grooves, avoiding the phenomenon of over-dense or over-sparse seed sowing, and improving the uniformity and quality of seedling raising.

[0023] 3. Avoid repeated sowing: The device is designed with a ratchet mechanism, so that when the equipment moves backward, the cloth disk stops rotating and the sowing mechanism no longer continues to sow seeds, thereby effectively avoiding the phenomenon of repeated sowing of seeds during backward movement. This design not only reduces the waste of seeds but also prevents the adverse effects of repeated sowing on crop growth, improving the sowing accuracy and resource utilization efficiency.

[0024] In summary, the present invention provides a highly efficient, precise, and easy-to-operate scallion seedling raising and sowing device, which significantly improves the efficiency and quality of scallion seedling raising and has broad application prospects.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-6 A device for raising and sowing green onion seedlings comprises an assembly frame 1, both sides of which are rotatably mounted with front wheels 11 and rear wheels 12, and the two sets of rear wheels 12 are fixedly connected by a connecting shaft 121.

[0034] It also includes a seed box 2 and a sowing mechanism 3. The seed box 2 is fixedly installed on the assembly frame 1. The sowing mechanism 3 includes a circular outer cover 31, a feeding disc 32, a feeding pipe 33, and a feeding pipe 34. The circular outer cover 31 is connected with the feeding pipe 33 and the feeding pipe 34. The feeding pipe 33 is connected with the bottom of the seed box 2, and the feeding pipe 34 extends to the bottom of the assembly frame 1. The feeding disc 32 is rotatably installed in the circular outer cover 31 and is tightly attached to the inner wall of the circular outer cover 31. The outer edge of the feeding disc 32 is evenly provided with storage grooves 321.

[0035] It also includes a soil-opening shovel 41 and a soil-covering shovel 42 fixedly installed below the assembly frame 1. The soil-opening shovel 41 and the soil-covering shovel 42 are respectively arranged on the front and rear sides of the blanking connecting pipe 34.

[0036] It also includes a transmission mechanism 5 assembled on the assembly frame 1. The transmission mechanism 5 is in power connection with the connecting shaft 121 and the cloth distributing plate 32.

[0037] Front wheels 11 and rear wheels 12 are installed on both sides of the assembly frame 1, which can stably support the assembly frame 1 and ensure that the assembly frame 1 travels stably between the ridges. During the travel of the assembly frame 1, the soil-opening shovel 41 installed at its bottom first acts on the ridge, opening a groove in the ridge, so that the sowing mechanism 3 evenly scatters the green onion seeds in the seed box 2 into the groove. Then, the soil-covering shovel 42 at the rear covers the groove with the green onion seeds, realizing the efficient seedling raising and sowing operation of green onions.

[0038] During the travel of the assembly frame 1, its rear wheels 12 and the connecting shaft 121 can drive the transmission mechanism 5 to operate, and then drive the cloth distributing plate 32 to rotate through the connecting shaft 121. Each storage groove 321 on the cloth distributing plate 32 can circulate between the feeding connecting pipe 33 and the blanking connecting pipe 34. When the storage groove 321 is at the feeding connecting pipe 33, the green onion seeds stored in the seed box 2 can fall into the storage groove 321 through the feeding connecting pipe. During the further rotation of the cloth distributing plate 32, the storage groove 321 filled with green onion seeds rotates to the position of the blanking connecting pipe 34 and falls from the blanking connecting pipe 34 into the excavated groove.

[0039] To facilitate the control of the movement of the assembly frame 1 between the ridges and ensure the stable contact and operation of the rear wheels 12 with the ground, a push handle 13 is fixedly installed at the tail of the assembly frame 1. When carrying out the seedling raising and sowing of green onions, by operating the push handle 13, the assembly frame 1 travels stably in the field and can make the rear wheels 12 stably contact the ground.

[0040] To ensure that the soil-opening shovel 41 and the soil-covering shovel 42 can be stably installed below the assembly frame 1 and at the same time realize the operations of grooving and soil covering, the following technical solutions are provided.

[0041] The soil-opening shovel 41 and the soil-covering shovel 42 are both fixedly installed on the assembly plate 43. The assembly plate 43 is fixedly installed at the bottom of the assembly frame 1. The soil-facing surface of the soil-opening shovel 41 is set as a sharp-angle structure 411, the soil-facing surface of the soil-covering shovel 42 is set as a wrapping structure 421, and an arc-shaped groove 422 is arranged at the bottom of the soil-covering shovel 42.

[0042] The soil-opening shovel 41 and the soil-covering shovel 42 are both welded to the assembly plate 43, and the assembly plate 43 can be installed at the bottom of the assembly frame 1 by means of bolt fixation, which is convenient for disassembly, assembly and replacement of soil-opening shovels 41 and soil-covering shovels 42 with different sizes and models.

[0043] When the pointed corner structure 411 on the front side of the soil-opening shovel 41 acts on the soil, it can separate the soil from both sides thereof to dig a trench for planting. The wrapping structure 421 on the front side of the soil-covering shovel 42 can push the soil on both sides of the trench back into the trench to bury the sown seeds, and the arc-shaped groove 422 at the bottom can shape the backfilled soil to make it present an arc-shaped protrusion.

[0044] The blanking connecting pipe 34 needs to be arranged through the assembly frame 1 and the assembly plate 43 to ensure that the green onion seeds in the blanking pipe can be effectively sown into the trench.

[0045] To ensure that the seed box 2 can be stably installed on the assembly frame 1 and the seed box 2 is arranged higher than the sowing mechanism 3 so that the green onion seeds stored in the seed box 2 can be stably conveyed through the feeding connecting pipe 33, an assembly bracket 21 is fixedly installed on the assembly frame 1, the seed box 2 is fixedly installed on the assembly bracket 21, and the feeding connecting pipe 33 is arranged obliquely upward.

[0046] The assembly bracket 21 is installed on the assembly frame 1 by means of bolt fixation, and the seed box 2 is assembled to the assembly frame 1 by means of welding, which can ensure that the seed box 2 is stably installed on the assembly frame 1 and ensure that the seed box 2 is arranged higher than the sowing mechanism 3.

[0047] To ensure that the transmission mechanism 5 can be stably installed on the assembly frame 1 and realize the stable transmission of the power of the rear wheel 12 to the sowing mechanism 3, the following technical solutions are provided.

[0048] The transmission mechanism 5 includes a transmission shaft 51, a rotating seat 52, and a ratchet mechanism. The transmission shaft 51 and the rotating seat 52 are both rotatably installed on the assembly frame 1 and are coaxially arranged. The connecting shaft 121 is in power connection with the transmission shaft 51, and the cloth distributing disc 32 is in power connection with the rotating seat 52.

[0049] The ratchet mechanism includes an inner ratchet 531, a pawl 532, and a reed 533. The inner ratchet 531 is arranged in the rotating seat 52. The pawl 532 is rotatably installed around the transmission shaft 51 and is in engagement with the inner ratchet 531. The reed 533 is assembled between the pawl 532 and the transmission shaft 51.

[0050] An installation frame is welded on the assembly frame 1 to stably install the transmission shaft 51 and the rotating seat 52 on the installation frame.

[0051] The reed 533 can ensure that the pawl 532 always has a tendency to open outward and is engaged with the inner ratchet 531. The power of the rear wheel 12 can be transmitted to the transmission shaft 51 and drive the pawl 532 thereon to operate. When the assembly frame 1 moves forward, the pawl 532 rotates forward and can drive the inner ratchet 531 and the rotating seat 52 to operate. The rotating seat 52 drives the cloth distributing disc 32 to operate to sow the green onion seeds.

[0052] When the excavated trench is unqualified and needs to be re-excavated, the assembly frame 1 retreats. At this time, the rear wheel 12 drives the transmission shaft 51 and the ratchet 532 thereon to rotate in the reverse direction. The ratchet 532 and the internal ratchet wheel 531 are in a slipping state, while the internal ratchet wheel 531, the rotating seat 52, and the cloth distributing disc 32 are all in a stationary state, and the scallion seeds stop being sown, avoiding repeated sowing of scallions in the trench.

[0053] To ensure that the power of the rear wheel 12 can be stably transmitted to the transmission shaft 51 through the connecting shaft 121, and to ensure that the power of the rotating seat 52 can be stably transmitted to the cloth distributing disc 32, the following technical solutions are provided.

[0054] A driving sprocket A122 is fixedly connected to the connecting shaft 121, a driving sprocket A511 is fixedly connected to the transmission shaft 51, and the driving sprocket A122 and the driving sprocket A511 are chain-driven through a chain. A driving sprocket B521 is fixedly connected to the rotating seat 52, and a driving sprocket B322 arranged outside the circular outer cover 31 is fixedly connected to the center of the cloth distributing disc 32. The driving sprocket B521 and the driving sprocket B322 are chain-driven through a chain.

[0055] The power of the rear wheel 12 can be transmitted to the driving sprocket A511 through the driving sprocket A122 and drive the transmission shaft 51 to rotate. After the power direction is screened by the ratchet assembly, when the rotating seat 52 rotates, the cloth distributing disc 32 can be driven to rotate stably through the driving sprocket B521 and the driving sprocket B322.
