Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery components technology, specifically to an adjustable press wheel. Background Technology

[0002] In the soil covering and compaction machinery of seeders, the existing soil covering and compaction wheels generally use two compaction wheels mounted on a wheel frame to compact the soil. However, the compaction wheels lack corresponding adjustment functions for different soil conditions, which has certain limitations. As a result, the soil covering and compaction effect is not ideal under unsuitable soil conditions. Therefore, a new compaction wheel structure is needed to address the problem of the difficulty in adjusting the existing compaction wheels. Utility Model Content

[0003] This invention proposes an adjustable compaction wheel, which solves the problem that the lack of adjustment function in existing compaction wheels leads to unsatisfactory compaction effects for different soil types.

[0004] The technical solution of this utility model is as follows:

[0005] An adjustable press wheel includes a wheel frame body, a bushing, a main shaft, and wheel bodies. The bushing is disposed at one end of the wheel frame body, and the other end of the wheel frame body is a hinged mounting end. The main shaft is inserted into the bushing, and both ends of the main shaft are inclined shafts. Two wheel bodies are respectively rotatably disposed at both ends of the main shaft. The press wheel also includes a wheel angle adjustment plate, a press frame, a press spring, and a press adjustment plate. One end of the wheel angle adjustment plate is connected to the main shaft, and the other end is selectively limited and locked to the wheel frame body. The press frame is sleeved on the bushing. One end of the press adjustment plate is connected to the press frame, and the other end of the press adjustment plate is selectively limited and locked to the wheel frame body. The press spring is disposed on one side of the press adjustment plate and has a hook mounting end.

[0006] The press wheel also includes an arc-shaped positioning plate, a positioning pin, and a positioning spring. Two arc-shaped positioning plates are disposed on the wheel frame body. Multiple positioning holes are spaced apart on the arc-shaped positioning plates. The positioning pin and the positioning spring are a set and are disposed in two sets. The wheel angle adjusting plate and the press adjusting plate are both provided with the positioning pin. The positioning spring is sleeved on the positioning pin and acts on the positioning pin to make the positioning pin insert into the positioning hole.

[0007] Two compression springs are provided and are parallel to each other.

[0008] The pressing sides of the two wheels are close to each other, and the angle between the wheels and the vertical direction is 30°.

[0009] The wheel frame body includes a first wheel frame plate, a second wheel frame plate, and a connecting plate. The first wheel frame plate and the second wheel frame plate are parallel to each other and spaced apart. The connecting plate is disposed between the first wheel frame plate and the second wheel frame plate.

[0010] The working principle and beneficial effects of this utility model are as follows:

[0011] This utility model discloses an adjustable pressing wheel. A bushing is installed at one end of the wheel frame body, and a main shaft is installed inside the bushing. The two ends of the main shaft are inclined to form an inclined shaft. After the wheel bodies are installed, the wheel bodies on both sides of the main shaft form an inclined angle installation configuration. When the two wheel bodies are inclined, they are at a minimum distance from each other. By installing a wheel angle adjustment plate connected to the main shaft, the swinging of the wheel angle adjustment plate causes the main shaft to swing within the bushing, thereby adjusting the two wheel bodies to contact the ground at different wheel angles, i.e., different wheel distances to achieve pressing. In addition, one end of the pressing frame is fitted onto the bushing, and a pressing adjustment plate is connected to the pressing frame. A [missing information - likely a design feature] is provided on one side of the pressing adjustment plate. The compression spring has a hook-mounted end for mounting on the main body. Simultaneously, the hinged mounting end of the wheel frame is also hinged to the main body. The spring's tension causes the wheel frame to press down towards the wheel's compression side around the hinged connection. The compression adjustment plate can be adjusted by swinging around the bushing of the compression frame, thereby adjusting the spring force of the compression spring and thus adjusting the pressure of the wheel contacting the soil. Both the compression adjustment plate and the wheel angle adjustment plate can be selectively locked to the wheel frame after being adjusted to different positions, resulting in different working states of the compression wheel. Different compression pressures and wheel spacings are used to achieve soil compression, adapting to different soil conditions and improving the compression effect. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1-3 As shown, this embodiment proposes an adjustable press wheel, which includes a wheel frame body 1, a bushing 2, a main shaft 3, and wheel bodies 4. The bushing 2 is disposed at one end of the wheel frame body 1, and the other end of the wheel frame body 1 is a hinged mounting end. The main shaft 3 is inserted into the bushing 2, and both ends of the main shaft 3 are inclined shafts. The two wheel bodies 4 are respectively rotatably disposed at both ends of the main shaft 3. The press wheel also includes a wheel angle adjustment plate 5, a press frame 6, a press spring 7, and a press adjustment plate 8. One end of the wheel angle adjustment plate 5 is connected to the main shaft 3, and the other end is selectively limited and locked to the wheel frame body 1. The press frame 6 is sleeved on the bushing 2. One end of the press adjustment plate 8 is connected to the press frame 6, and the other end of the press adjustment plate 8 is selectively limited and locked to the wheel frame body 1. The press spring 7 is disposed on one side of the press adjustment plate 8, and the press spring 7 has a hook mounting end.

[0019] In this embodiment, an adjustable pressing wheel is disclosed. A bushing 2 is installed on one end of the wheel frame body 1, and a main shaft 3 is installed inside the bushing 2. The two ends of the main shaft 3 are inclined to form an inclined shaft. After the wheel bodies 4 are installed, the wheel bodies 4 on both sides of the main shaft 3 form an inclined angle installation configuration. When the two wheel bodies 4 are inclined, they are close together with a minimum distance. By installing a wheel angle adjustment plate 5, which is connected to the main shaft 3, the swinging of the wheel angle adjustment plate 5 will cause the main shaft 3 to swing within the bushing 2, thereby adjusting the two wheel bodies 4 to contact the ground at different wheel angles, that is, to achieve pressing with different wheel distances. In addition, one end of the pressing frame 6 is sleeved on the bushing 2. A pressing adjustment plate 8 is connected to the frame 6. A pressing spring 7 is provided on one side of the pressing adjustment plate 8. The other end of the pressing spring 7 is hooked for mounting on the main body. At the same time, the hinged mounting end of the wheel frame body 1 is also hinged to the main body. The tension of the spring causes the wheel frame body 1 to press down in the direction of the pressing side of the wheel body 4 around the hinged connection. The pressing adjustment plate 8 can be adjusted by swinging around the bushing 2 with the pressing frame 6, thereby adjusting the elastic force of the pressing spring 7, so that the pressure of the wheel body 4 in contact with the soil can be adjusted. The pressing adjustment plate 8 and the wheel angle adjustment plate 5 can be selectively locked to the wheel frame body 1 after being adjusted to different positions, thereby producing different working states of the pressing wheel.

[0020] The press wheel also includes an arc-shaped positioning plate 9, a positioning pin 10, and a positioning spring 11. Two arc-shaped positioning plates 9 are disposed on the wheel frame body 1. Multiple positioning holes 12 are provided at intervals on the arc-shaped positioning plates 9. The positioning pin 10 and the positioning spring 11 are a group and are disposed in two groups. The wheel angle adjusting plate 5 and the press adjusting plate 8 are both provided with the positioning pin 10. The positioning spring 11 is sleeved on the positioning pin 10 and acts on the positioning pin 10 to insert the positioning pin 10 into the positioning hole 12.

[0021] In this embodiment, the locking structure between the wheel angle adjustment plate 5 and the positive pressure adjustment plate and the wheel frame body 1 is specifically as follows: two arc-shaped positioning plates 9 are provided on the wheel frame body 1, and multiple positioning holes 12 are provided on the arc-shaped positioning plates 9. Positioning pins 10 are provided on the wheel angle adjustment plate 5 and the positive pressure adjustment plate 8. Positioning springs 11 are fitted on the positioning pins 10. The positioning springs 11 act on the positioning pins 10, so that they can be stably inserted into the positioning holes 12 to achieve locking.

[0022] Two compression springs 7 are provided and are parallel to each other.

[0023] In this embodiment, two compression springs 7 are used. The two springs are parallel in arc shape to provide stronger and more stable compression pressure, resulting in smoother movement.

[0024] The pressing sides of the two wheels 4 are close to each other, and the angle between the wheels 4 and the vertical direction is 30°.

[0025] In this embodiment, the wheels 4 are close to each other on the pressing side to press the soil. The angle between the wheels 4 and the vertical direction is 30°, which better compresses the soil and makes the seeds in close contact with the soil, which is conducive to the seeds absorbing water and germinating.

[0026] The wheel frame body 1 includes a first wheel frame plate 13, a second wheel frame plate 14, and a connecting plate 15. The first wheel frame plate 13 and the second wheel frame plate 14 are parallel to each other and spaced apart. The connecting plate 15 is disposed between the first wheel frame plate 13 and the second wheel frame plate 14.

[0027] In this embodiment, the wheel frame body 1 adopts a first wheel frame plate 13 and a second wheel frame plate 14 arranged in parallel and connected in the middle by a connecting plate 15. The ends of the first wheel frame plate 13 and the second wheel frame plate 14 are connected to the bushing 2 to form a stable support structure.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
