Description

Technical Field

[0001] This utility model relates to the field of seeding machine technology, and in particular to a high-efficiency small-particle medicinal herb seeding machine. Background Technology

[0002] Seeders are indispensable and essential pieces of machinery in modern agriculture, greatly improving the efficiency and quality of crop cultivation. They are primarily used to precisely place seeds into the soil, ensuring crops grow at appropriate spacing and depth. Integrating advanced mechanical technology and intelligent control systems, they can adjust the seeding rate, spacing, and depth according to the farmer's needs, making the sowing process more precise and efficient. With continuous advancements and innovations in agricultural technology, the performance and quality of seeders are constantly improving. Various types of seeders are widely used in agricultural production, providing farmers with more efficient and convenient sowing methods. The working principle of a seeder is based on steps such as seed storage, conveying, soil preparation, sowing, and covering. Farmers simply place the seeds into the seeder's storage container, and through the combined action of mechanical force and power, the seeds are precisely placed into the soil. Seeders can also automatically adjust sowing parameters to adapt to the needs of different crops and land types. However, existing seeders have complex structures and are only suitable for large-scale planting; for small-area sowing needs, production costs are high.

[0003] A search of Chinese utility model patent (publication number CN222655732U) reveals a seeder, including a housing, a first discharge channel, a first clearance channel, a material tray, a discharge port, a baffle, a second discharge channel, a second clearance channel, a drive wheel assembly, a cam, a protrusion, and a push block. The protrusion collides with the push block, driving the push block forward, thereby making the second discharge channel on the baffle, the discharge port, and the first discharge channel in the same vertical extension direction. Seeds pass through the first discharge channel for sowing. The overall structure is simple and the operating cost is low.

[0004] However, practical application has revealed that this technical solution still has at least the following drawbacks: The protrusion collides with the pusher, driving the pusher forward. This causes the second discharge channel on the baffle to be aligned with the discharge port and the first discharge channel in the same vertical direction. When seeds pass through the first discharge channel for sowing, for small-particle medicinal seeds that are lightweight and highly mobile, when the first discharge channel forms a smooth vertical drop path, the seeds will exceed the proper seeding control threshold under the influence of gravity. This results in a large number of seeds falling continuously in a short period of time, making it difficult to control the seeding accuracy, causing seed waste and increasing the cost of subsequent seedling thinning. Utility Model Content

[0005] The present invention aims to provide a high-efficiency small-particle medicinal herb seeder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency small-particle medicinal herb seeder includes a housing, a push handle connected to the housing, two sets of rotating shafts rotatably connected to the housing, each set of rotating shafts connected to a drive wheel, a roller connected to any one of the rotating shafts, a soil-digging block connected to the roller, an operating opening in the housing, a drive shaft connected to the housing, a pulley assembly connected to the drive shaft and any one of the rotating shafts, a seeding opening in the housing, a seeding cylinder connected to the drive shaft, the seeding cylinder cooperating with the seeding opening, a flow guide baffle connected to the housing, the flow guide baffle cooperating with the seeding cylinder, a seeding groove in the seeding cylinder, and a soil leveling structure connected to the housing.

[0007] Preferably, the leveling structure includes leveling blocks, the box body is slidably connected to a connecting rod, the connecting rod is connected to a limit block, the end of the connecting rod away from the limit block is connected to the leveling block, and a spring is sleeved on the outside of the connecting rod, with both ends of the spring connected to the box body and the leveling block respectively.

[0008] Preferably, the flat soil block and the box are connected together by a protective cover, the spring is located inside the protective cover, and the protective cover is made of a flexible material.

[0009] Preferably, the flow guide baffle is connected to a protective strip, and the protective strip abuts against the seeding cylinder.

[0010] Preferably, the protective strip has a movable groove, and a ball bearing is movably connected to the inner wall of the movable groove, the ball bearing contacting the seeding cylinder.

[0011] Preferably, the housing is connected to a flow guide block.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows: (1) This technical solution combines a push handle with a drive wheel, facilitating manual operation or traction. The soil-digging blocks rotate with the shaft, allowing for simultaneous digging operations and reducing process connection time. The belt pulley assembly efficiently transmits the power from the shaft to the drive shaft, driving the seeding cylinder to rotate precisely. The seed slots systematically receive small seeds, enabling precision sowing and avoiding seed waste. The leveling structure immediately levels the soil after sowing, ensuring even seed coverage and a favorable germination environment. The entire device integrates digging, sowing, and covering processes, significantly improving sowing efficiency and quality while reducing labor and time costs.

[0013] (2) By setting springs, the leveling blocks can adapt to different terrain undulations and fit closely to the ground for leveling operations, avoiding uneven soil covering caused by uneven ground, and creating a stable germination environment for small-particle medicinal seed. The cooperation between the limiting block and the connecting rod can prevent the leveling blocks from excessively displacing and leaving the working range, and ensure that they can slide up and down under the action of the spring to achieve dynamic leveling.

[0014] (3) By setting up a protective cover, soil, sand and gravel can be blocked from entering the spring area, preventing the spring from failing due to jamming and wear, extending the service life of the spring and the stability of the leveling structure. In addition, the flexible protective cover can deform naturally with the movement of the leveling block, without affecting the elasticity of the spring and the normal displacement of the leveling block.

[0015] (4) By setting anti-slip strips, the gap between the guide baffle and the seeding cylinder can be filled, preventing seeds from getting stuck in the gap, ensuring that the seeding cylinder rotates at a uniform speed, reducing the risk of mechanical failure, extending the service life of the device, and reducing the frequency of maintenance.

[0016] (5) By setting up movable grooves and ball bearings, the sliding friction between the protective strip and the seeding cylinder can be converted into rolling friction, which reduces frictional resistance, makes the seeding cylinder rotate more smoothly, reduces component wear, and extends the service life of the device.

[0017] (6) By setting up guide blocks, a clear sliding path is provided for the soil that sticks to and falls off the excavation block, so that it can slide out of the box smoothly, avoiding the burden of equipment operation due to excessive soil accumulation, reducing the risk of bacteria growth and corrosion of the box due to soil residue, reducing equipment cleaning and maintenance costs, ensuring long-term stable operation of the seeder, and improving overall work efficiency and service life.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: like Figure 1-3The high-efficiency small-particle medicinal herb seeder includes a housing 1, with a push handle 2 connected to the side wall of the housing 1. Two sets of rotating shafts 6 are rotatably connected to the housing 1, and drive wheels 9 are connected to both ends of each set of rotating shafts 6. A roller 7 is connected to the middle of any rotating shaft 6, and two sets of centrally symmetrical digging blocks 5 are connected to the side wall of the roller 7. An operating opening 4 is provided on the bottom wall of the housing 1, and the roller 7 is located inside the operating opening 4, allowing the digging blocks 5 to contact the soil and dig. A guide block 8 is connected to the housing 1, located inside the housing 1 near the dead corner of the operating opening 4.

[0020] like Figure 1-3 As shown, the housing 1 is connected to a drive shaft 15, which, together with the rotating shaft 6 connected to the roller 7, is connected to a pulley assembly 22. A seeding port 17 is provided on the bottom wall of the housing 1, and a seeding cylinder 16 is connected to the drive shaft 15, which mates with the seeding port 17. A flow guide baffle 3 is connected to the inner wall of the housing 1, located on the left and right sides of the seeding cylinder 16, collecting seeds at the seeding cylinder 16. A protective strip 20 is connected to the flow guide baffle 3, and a movable groove 19 is provided on the side of the protective strip 20 closest to the seeding cylinder 16. A ball bearing 18 is movably connected to the inner wall of the movable groove 19, and the ball bearing 18 abuts against the seeding cylinder 16. The side wall of the protective strip 20 is infinitely close to the seeding cylinder 16. Two symmetrical sets of seeding slots 21 are provided on the side wall of the seeding cylinder 16, corresponding to two sets of excavated soil blocks 5.

[0021] like Figure 1 As shown, the box body 1 is connected to a leveling structure, which includes leveling blocks 10. Several sets of connecting rods 13 are slidably connected to the bottom wall of the box body 1. The top ends of the connecting rods 13 are located inside the box body 1 and connected to limit blocks 14. The end of the connecting rod 13 away from the limit blocks 14 is located outside the box body 1 and connected to the leveling blocks 10. A spring 11 is sleeved on the outside of the connecting rod 13, and both ends of the spring 11 are connected to the bottom wall of the box body 1 and the top wall of the leveling blocks 10, respectively. A protective cover 12 is connected to the top wall of the leveling blocks 10 and the bottom wall of the box body 1. The spring 11 is located inside the protective cover 12, which is made of flexible material.

[0022] The operator grips the push handle 2 to push the seeder, causing the drive wheels 9 at both ends of the two sets of rotating shafts 6 to roll on the ground, driving the shafts 6 to rotate. The roller 7 connected to one of the rotating shafts 6 rotates synchronously. As the roller 7 passes the operating opening 4, two sets of digging blocks 5, symmetrically positioned on its side wall, cut into the soil, turning it over to form a seeding pit. After digging, the digging blocks 5 leave the soil, awaiting the next cycle. During this process, any remaining soil on the digging blocks 5 falls off under gravity. Inside the housing 1, near the dead corner of the operating opening 4, the guide block 8, with its specific tilt angle and curved surface design, guides the soil along the guide path, preventing soil accumulation in the dead corner and ensuring smooth equipment operation. The rotating shaft 6 connecting the roller 7 transmits power to the drive shaft 15 via the pulley assembly 22, which drives the seeding cylinder 16 to rotate. The guide baffle 3 on the inner wall of the box 1 collects the seeds above the sowing cylinder 16. As the sowing cylinder 16 rotates, the seed slots 21 on the side wall pass through the seed collection area in sequence, scooping up a fixed amount of small medicinal herb seeds. On the protective strip 20 connected to the guide baffle 3, the ball bearings 18 in the movable groove 19 abut against the sowing cylinder 16 to prevent seeds from leaking out of the gaps or getting stuck in the gaps, ensuring that the seeds can only be discharged in an orderly manner through the seed slots 21. As the sowing cylinder 16 continues to rotate, the seed slots 21 carry the seeds to a position aligned with the sowing opening 17. Under the action of gravity, the seeds fall through the sowing opening 17 into the pit below, which is dug by the excavation block 5. After the seeds are sown, the leveling structure begins to work. Under the elastic support of the spring 11, the leveling block 10 always maintains a certain pressure with the ground, adaptively conforming to different terrain undulations. When the seeder moves forward, the leveling block 10 pushes back the excavated soil, covering the seeds to complete the covering operation.

[0023] The specific implementation process is as follows: In operation, the operator holds the push handle 2, places the seeder at the starting position of the plot, adjusts the direction to align the sowing path with the plan, and places an appropriate amount of seeds into the guide baffle 3 inside the housing 1. Pushing the seeder forward, the drive wheel 9 moves the equipment, the digging block 5 begins to dig the pit, and simultaneously the pulley assembly 22 transmits power, causing the sowing cylinder 16 to rotate and distribute the seeds into the pit. The seeder continues to move forward, and the leveling block 10 then completes the covering and leveling work. This cycle continues until the sowing operation for the entire plot is completed.

[0024] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
