Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, specifically relating to a seeder adaptable to various terrains. Background Technology

[0002] In agricultural production, seeders are essential equipment for achieving efficient sowing. With the development of agricultural modernization, seeders need to adapt to different terrain conditions for sowing operations. In multi-terrain environments, especially in hilly and mountainous areas with sloping ground, seeders not only need good maneuverability to smoothly overcome obstacles such as bumps and depressions in the ground, but also need to ensure the accuracy of sowing.

[0003] However, in existing technologies, to improve the seeder's maneuverability in complex terrain, the feed pipe is usually positioned high above the ground to avoid collisions with ground obstacles. But when sowing on slopes, this configuration causes seeds, after being discharged from the feed pipe, to deviate from their intended trajectory due to gravity and the slope's surface. They may not fall accurately into the pre-dug trenches, instead landing outside the trenches, thus reducing sowing quality and affecting crop germination rates and subsequent growth. Therefore, how to flexibly adjust the feed pipe height while ensuring good seeder maneuverability, allowing seeds to accurately fall into the trenches, has become a pressing technical problem. Utility Model Content

[0004] The purpose of this invention is to provide a seeder that is adaptable to various terrains, aiming to solve the problem that in the prior art, when the seeder is used to sow on a slope, the seeds tend to fall outside the soil furrows, resulting in low sowing quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seeder adaptable to various terrains, including a frame and a handrail at the rear of the frame. Side frames are provided at the bottom of both sides of the frame, and a roller is rotatably connected to one side of the side frame. A fixed frame is provided on the frame, and multiple seeding components are provided on the fixed frame. A feed pipe is provided below the seeding components, and a sleeve is movably sleeved on the outside of the feed pipe. A drive component for vertically raising and lowering the sleeve is provided on the frame.

[0006] By adopting the above-mentioned design and mounting the rollers on the side frames of the machine frame, the height of the chassis in the middle of the frame can be effectively increased. This design allows the seeder to adapt to soil ridging at different heights and provides good maneuverability. During sowing operations, the height of the sleeve can be flexibly adjusted via the drive assembly to maintain an appropriate distance from the ground soil. Especially when sowing on sloping terrain, the longer sleeve can guide the direction of seed descent, ensuring that the seeds accurately fall into the pre-dug soil trenches and guaranteeing sowing quality.

[0007] As a preferred embodiment of this invention, the plurality of seeding components can be adjusted at equal intervals to adapt to different soil trench spacings.

[0008] By adopting the above solution, multiple seeding components can be adjusted at equal intervals, enabling the seeder to quickly adapt to different planting needs without frequent equipment changes, thus greatly improving the seeder's operational flexibility in different planting scenarios.

[0009] In a preferred embodiment of the present invention, the drive assembly includes a connecting block and a movable frame. The connecting block is fixedly connected to one side of the sleeve, the movable frame slides vertically on the frame and passes through the frame, a horizontal plate is fixedly connected to the bottom of the movable frame, a connector connected to the sleeve is fixedly connected to the horizontal plate, and a compression spring that can elastically support the frame upward is provided between the movable frame and the frame.

[0010] By employing the above scheme, when the movable frame is pressed by hand, the compression spring is compressed, causing the movable frame to move the horizontal plate downwards simultaneously. This, in turn, causes the connecting piece to move downwards, thus reducing the height of the sleeve on the connecting piece. After the movable frame is released, the compression spring returns to its original deformation, generating force to push the sleeve back to its original position. By controlling the pressure applied to the movable frame, the sleeve height can be flexibly adjusted. This operation method is simple and convenient, facilitating rapid adjustments in actual operations.

[0011] In a preferred embodiment of this invention, the connector is a crossbar structure, and the connecting block is slidably sleeved on the connector.

[0012] By adopting the above solution, the distance between the seeding components can be adjusted according to usage requirements without affecting the vertical movement of the sleeve.

[0013] In a preferred embodiment of this utility model, the fixing frame is provided with a crossbeam, and multiple mounting blocks are slidably sleeved on the crossbeam. The number of mounting blocks matches the number of sowing components. A column is provided on one side of each mounting block. Sliding grooves are provided on both sides of the fixing frame. A lifting plate is provided on one side of the fixing frame. Multiple guide grooves adapted to the column are provided on the lifting plate. A screw is rotatably connected to one side of the lifting plate. A turntable is fixedly connected to the end of the screw. A support plate is fixedly connected to the top of the fixing frame. The screw is threadedly connected to the support plate.

[0014] By adopting the above scheme, the turntable drives the screw to rotate, which in turn drives the lifting plate to move up or down. During this process, the guide groove guides the column to move, causing the distance between the installation blocks to change, thereby achieving equal spacing adjustment of the seeding components.

[0015] As a preferred embodiment of this utility model, two symmetrically distributed support rods are provided at the bottom of the frame near the handrail, and the bottom ends of the support rods are fixedly connected to a base.

[0016] By adopting the above scheme, the two-wheel design allows the seeder to maintain good flexibility, and when the handle is released, the base at the bottom of the support rod will contact the ground, providing support for the seeder and making it more stable, which is conducive to adding seeds into the seeding unit.

[0017] As a preferred embodiment of this invention, a diagonal brace is provided between the support rod and the frame.

[0018] By adopting the above scheme, a triangular support structure is formed between the diagonal rod, the strut, and the frame, which can improve the structural stability of the strut and prevent it from deforming.

[0019] In a preferred embodiment of this utility model, there are two crossbeams, which are arranged parallel to each other in the vertical direction.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. By adjusting the vertical height of the seed canopy using the drive assembly, the canopy can be lowered to a predetermined height when operating on slopes, directly guiding the seeds to accurately fall into the soil furrows. This effectively overcomes the deviation in landing point caused by gravity offset or slope bounce, significantly improving sowing accuracy. Simultaneously, the rollers are mounted on the side frame, increasing the chassis's ground clearance and preventing the seed canopy from colliding with obstacles on rough terrain. This balances the needs for both passability and sowing precision, improving sowing quality and ensuring the later growth of crops.

[0022] 2. By setting up seeding components with adjustable spacing, it can quickly adapt to the soil furrow spacing requirements of different crops and different planting areas, eliminating the need for frequent equipment changes. This improves the operational flexibility of the seeder in diverse planting scenarios, allowing one machine to meet multiple planting tasks and increase equipment utilization.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figures 1-4 A seeder adaptable to various terrains includes a frame 1 and a handrail 11 located at the rear of the frame 1. Side frames 12 are fixedly welded to the bottom of both sides of the frame 1. One side of each side frame 12 is rotatably connected to a roller 13 via a bearing. This structure effectively raises the chassis height in the middle of the frame 1, allowing the seeder to adapt to different soil ridging heights and providing good maneuverability in complex terrains such as hills and mountains. A fixed frame 2 is fixedly installed on the frame 1, and multiple seeding components 3 are mounted on the fixed frame 2. A feed pipe 4 is located below the seeding components 3, and a sleeve 41 is movably fitted onto the outer side of the feed pipe 4. The inner diameter of the sleeve 41 is slightly larger than the outer diameter of the feed pipe 4 to ensure smooth up-and-down movement of the sleeve 4 along the feed pipe 4. A drive assembly on the frame 1 is used to drive the sleeve 41 vertically up and down. Specifically, the drive assembly includes a connecting block 42 and a movable frame 45. The connecting block 42 is fixedly connected to one side of the sleeve 41 by welding. A horizontal plate 44 is fixedly connected to the bottom of the movable frame 45 by welding. Connecting parts 43, matching the number of sleeves 41, are welded onto the horizontal plate 44. The connecting parts 43 are fixedly connected to the connecting block 42. A compression spring 46 is provided between the movable frame 45 and the frame 1. In this embodiment, the sowing assembly 3 is a commonly used structure in this technical field, including conventional components such as a seed storage bin and a seed metering device, which will not be described in detail here.

[0032] In actual operation, on flat or downhill roads, workers can hold the handle 11 with one hand and press the movable frame 45 with the other while observing the height of the sleeve 41 to carry out sowing. On uneven or uphill roads, the seeder is more difficult to control. In this case, workers hold the handle 11 with both hands to keep the seeder stable, while another worker presses the movable frame 45 for assistance. When the movable frame 45 is pressed down, the compression spring 46 is compressed, and the movable frame 45 moves the horizontal plate 44 down, which in turn causes the connecting piece 43 to move the connecting block 42 and the sleeve 41 down, thereby lowering the height of the sleeve 41. After releasing the movable frame 45, the sleeve 41 returns to its original position under the force generated by the recovery deformation of the compression spring 46. By controlling the pressure of pressing the movable frame 45, the height of the sleeve 41 can be flexibly adjusted. When sowing on sloping ground, the sleeve 41 can be lowered to a predetermined height so that the seeds fall accurately into the pre-dug soil trench.

[0033] Furthermore, two symmetrically distributed support rods 5 are provided at the bottom of the side of the frame 1 near the handrail 11, and the bottom end of the support rods 5 is fixedly connected to the base 51.

[0034] The two-wheel design allows the seeder to maintain good flexibility, and when the handle 11 is released, the base 51 at the bottom of the support 5 will contact the ground, providing support for the seeder and making it more stable, which is conducive to adding seeds into the seeding assembly 3.

[0035] Furthermore, a diagonal brace 52 is provided between the strut 5 and the frame 1.

[0036] The diagonal brace 52, the strut 5, and the frame 1 can form a triangular support structure, which can improve the structural stability of the strut 5 and prevent it from deforming.

[0037] Example 2

[0038] Please see Figure 1 and Figure 4This embodiment includes the above-described embodiment, and further includes: multiple seeding components 3 can be adjusted at equal intervals; the connecting member 43 is a horizontal bar structure; the connecting block 42 is slidably sleeved on the connecting member 43; and the distance between the seeding components 3 can be adjusted according to usage requirements without affecting the up-and-down movement of the sleeve 41. The specific adjustment structure is as follows: two horizontal beams 21 are provided on the fixed frame 2, which are arranged parallel to each other in the vertical direction. Multiple mounting blocks 22 are slidably sleeved on the horizontal beams 21, and the number of mounting blocks 22 matches the number of seeding components 3. A column 221 is fixedly connected to one side of the mounting block 22; sliding grooves 24 are provided on both sides of the fixed frame 2, and a lifting plate 23 is vertically slidably arranged on the fixed frame 2 through the sliding grooves 24. Multiple inclined guide grooves 231 adapted to the column 221 are provided on the lifting plate 23. The guide groove 231 is a strip-shaped hole, and it is radially distributed with the lifting plate 23 as the center of symmetry. Each hole extends radially. The angle of the guide groove 231 is set so that when the lifting plate 23 is raised or lowered, the multiple mounting blocks 22 are adjusted at equal intervals on the crossbeam 21. This structure is existing technology and will not be described in detail here. A screw 25 is rotatably connected to one side of the lifting plate 23. A turntable 251 is fixed to the end of the screw 25. A support plate 26 is fixedly connected to the top of the fixing frame 2. The screw 25 and the support plate 26 are connected by threads.

[0039] By setting two crossbeams 21, the stability of the connection of the mounting blocks 22 can be improved, making the movement of the mounting blocks 22 smoother. When it is necessary to adjust the spacing of the seeding components 3, the turntable 251 is rotated, which drives the screw 25 to rotate. Since the screw 25 is threadedly connected to the support plate 26, the screw 25 can drive the lifting plate 23 to move up or down along the sliding grooves 24 on both sides of the fixed frame 2. During the movement of the lifting plate 23, the guide groove 231 moves through the guide column 221, causing the distance between the mounting blocks 22 to change, thereby realizing the equal spacing adjustment of the seeding components 3 to adapt to different soil trench spacings.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
