Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeder travel wheel technology, and in particular to seeder travel wheel structure suitable for different terrains. Background Technology
[0002] Seeders are key equipment for achieving precise seed sowing in agricultural production. Their wheels, as core components, not only support the weight of the machine but also drive it to move stably on different types of land (such as arable land, wasteland, muddy land, hard soil, etc.), directly affecting the efficiency and quality of sowing operations.
[0003] Traditional seeder wheels have a relatively simple structure. To adapt to the needs of walking on different terrains, some wheels are equipped with external walking plates to enhance traction. However, these walking plates are mostly designed to be directly welded to the wheel hub or integrally formed with the wheel hub, resulting in a fixed position and extension length. In actual operation, the softness of different soils varies significantly (e.g., loose sandy soil, heavy clay soil, and muddy soil are prone to sinking). The fixed structure of the walking plates cannot adjust the contact area and traction according to soil characteristics. When walking on hard ground, the excessive resistance can affect efficiency, while when walking on soft or muddy ground, the insufficient traction can cause the wheels to sink into the soil, making it difficult to adapt to diverse terrains. To solve the above problems, this utility model proposes a seeder wheel structure suitable for different terrains. Utility Model Content
[0004] The main purpose of this invention is to provide a seeder wheel structure suitable for different terrains, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A seeder traveling wheel structure suitable for different terrains includes an inner wheel ring. A first wheel hub is mounted on the side wall of the inner wheel ring via multiple spokes. Multiple mounting frames are fixedly connected to the side wall of the first wheel hub. A first support mechanism for supporting the traveling wheel is provided in the mounting frame. The first support mechanism includes a first ground plate slidably connected in the mounting frame. Two first bolts are fixedly connected to the side wall of the first ground plate. Two through slots are opened in the side wall of the mounting frame. A first nut is provided on the first bolt. A second support mechanism for supporting the traveling wheel is provided in the side wall of the mounting frame.
[0007] Preferably, the second support mechanism includes a second ground plate disposed on the side wall of the mounting frame, a fixing block fixedly connected to the inner wall of the second ground plate, and two second bolts passing through the side wall of the fixing block, with a second nut on the second bolt.
[0008] Preferably, the inner wall of the first wheel hub is provided with a plurality of mounting rods, the side wall of the spoke rod is fixedly connected to a mounting block, the side wall of the mounting block is fixedly connected to a third bolt, a second wheel hub is fixedly connected to the plurality of mounting rods, the side wall of the second wheel hub is provided with a tire, and a third nut is provided on the third bolt.
[0009] Preferably, the third bolt is provided with a second washer, and the first bolt sidewall is provided with a first washer.
[0010] Preferably, a limiting block is fixedly connected to the side wall of the spoke rod, and the side wall of the limiting block is provided with an arc surface.
[0011] Preferably, the tire sidewall has multiple grooves, and the multiple grooves are arranged at equal intervals.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. This device is equipped with a first support mechanism. The first ground-walking piece and the mounting frame adopt a sliding connection design. During operation, the contact area between the piece and the ground can be changed according to the softness of the soil (e.g., reduce the extension when walking on hard soil and increase the extension when walking on soft soil). This ensures low resistance when walking on hard ground and enhances the grip when walking on soft ground, thereby improving the adaptability to different soil hardness.
[0014] 2. This device is equipped with a second support mechanism. The second ground plate adopts a detachable design and can be flexibly added or removed as needed. After being added, it can significantly increase the contact area with the ground, reduce the pressure per unit area, effectively prevent the wheels from sinking into the mud, and improve the passability of extreme terrain.
[0015] 3. This device is equipped with a second wheel hub and tires. The second wheel hub can be installed on the side wall of the first wheel hub, so that the walking wheels can adapt to hard ground (such as roads and hardened field ridges) for operation. The tires can buffer the vibration when walking on hard ground, reduce the impact on the machine body, and at the same time avoid the wear caused by the walking plates directly contacting the hard ground, thus extending the service life of the equipment.

Detailed Implementation
[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] like Figure 1-7 As shown, the seeder's traveling wheel structure, suitable for different terrains, includes an inner wheel ring 1. A first wheel hub 3 is mounted on the side wall of the inner wheel ring 1 via multiple spokes 2. Multiple mounting frames 4 are fixedly connected to the side wall of the first wheel hub 3. A first support mechanism for supporting the traveling wheel is provided in the mounting frame 4. The first support mechanism includes a first ground-walking piece 5 slidably connected in the mounting frame 4. Two first bolts 9 are fixedly connected to the side wall of the first ground-walking piece 5. Two through slots 7 are opened in the side wall of the mounting frame 4. A first nut 8 is provided on the first bolt 9.
[0026] The side wall of the mounting frame 4 is provided with a second support mechanism for supporting the walking wheels. The second support mechanism includes a second ground plate 6 set on the side wall of the mounting frame 4. A fixing block 12 is fixedly connected to the inner wall of the second ground plate 6. Two second bolts 14 are provided through the side wall of the fixing block 12. A second nut 13 is provided on the second bolt 14. The second bolt 14 is fixedly connected to the mounting frame 4.
[0027] In this utility model, the inner wall of the first hub 3 is provided with multiple mounting rods 11, the side wall of the spoke rod 2 is fixedly connected with a mounting block 19, the side wall of the mounting block 19 is fixedly connected with a third bolt 18, the multiple mounting rods 11 are jointly fixedly connected with a second hub 15, the side wall of the second hub 15 is provided with a tire 16, and the third bolt 18 is provided with a third nut 17, so that the walking wheel can walk on hard ground.
[0028] In this utility model, a second washer 20 is provided on the third bolt 18, and a first washer 10 is provided on the side wall of the first bolt 9. The arrangement of the first washer 10 and the second washer 20 can increase the contact area between the bolts (first bolt 9, third bolt 18) and the connecting parts (mounting frame 4, mounting block 19), disperse the pressure during tightening, avoid deformation of the connecting parts due to excessive local stress, and enhance the stability of the bolt connection to prevent loosening caused by vibration during operation.
[0029] In this utility model, a limiting block 21 is fixedly connected to the side wall of the spoke rod 2. The side wall of the limiting block 21 is provided with an arc surface. The limiting block 21 can play a positioning role for the mounting rod 11, and quickly align the installation position when installing the second wheel hub 15, thereby improving assembly efficiency. The arc surface design can reduce friction and collision when the mounting rod 11 contacts the limiting block 21, avoid component wear, and protect the structural integrity.
[0030] In this utility model, the tire 16 has multiple grooves on its sidewall. The multiple grooves are evenly spaced, which can enhance the friction with hard ground. Especially when working on wet and slippery hard ground (such as roads after rain), it can effectively prevent slipping and improve walking stability. The evenly spaced design ensures that the tire 16 is evenly stressed, avoids excessive local wear, and extends the service life of the tire 16.
[0031] In the initial state, the inner rim 1 has a hole on its side wall (after the inner rim 1 is inserted into the axle and bearing, the hole is used to screw in bolts to fix the axle), the second ground plate 6 is removed from the mounting frame 4, and the second hub 15 is separated from the first hub 3.
[0032] When in use, the first walking piece 5 is slidably connected to the mounting frame 4. Loosen the first nut 8, adjust the extension length through the through groove 7, and then fix it by the first bolt 9 and the first nut 8. When walking on conventional farmland or soil with different hardness, the extension amount can be adjusted according to the soil characteristics (less extension for hard soil, more extension for soft soil). Then tighten the first nut 8 to ensure the balance between grip and resistance and achieve stable walking.
[0033] The second ground-walking plate 6 can adapt to muddy terrain: When encountering muddy ground, the second ground-walking plate 6 is installed on the side wall of the mounting frame 4 by means of the fixing block 12, the second bolt 14 and the second nut 13. The wide second ground-walking plate 6 can increase the contact area with the muddy ground, reduce the pressure, prevent the walking wheels from sinking into the mud, and ensure that the equipment passes through smoothly.
[0034] The second hub 15 and tire 16 can adapt to hard surfaces: when traveling on hard surfaces such as highways and hardened field ridges, the mounting rod 11 is attached to the side wall of the spoke rod 2, the third bolt 18 is passed through the hole on the mounting rod 11, and then the third nut 17 is screwed on to fix it. The elasticity of the tire 16 is used to buffer the impact of hard surfaces, and the grooves on the tire 16 are used to enhance the friction, avoid slipping and structural wear, and achieve stable travel.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
