Technical Field

[0001] This utility model relates to the field of agricultural production machinery, specifically to a roller wheelchair used for inter-row operations in traditional field planting. Background Technology

[0002] Strawberries are a fruit with high economic value and are widely grown in northern regions, mainly using greenhouse cultivation. Currently, the planting area is large in areas such as Beijing, Tianjin, and Hebei, but traditional ground cultivation is the main method. Traditional ground cultivation usually requires a lot of manpower from the strawberry planting period to the harvest period.

[0003] Traditional agricultural operations mainly involve manual bending over to manage plants. This method is not only labor-intensive and inefficient, but also easily leads to worker fatigue due to prolonged bending over, affecting production operations and speed. In addition, the narrow space between strawberry rows also brings inconvenience to management work. There is an urgent need to design a roller wheel for row operations in traditional ground planting to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a roller wheel for inter-row operations in traditional field planting, in order to overcome the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roller wheel for inter-row operation in traditional field planting methods includes a movable frame, with rollers rotatably fitted at both ends of the movable frame. A lead screw is threaded into the movable frame, and a support plate is rotatably fitted to the top of the lead screw. A support mechanism is provided between the movable frame and the support plate. A rotating column is rotatably fitted to the top of the support plate, and a cushioned seat is fixedly connected to the top of the rotating column. A backrest is rotatably fitted to one side of the cushioned seat, and a handle is installed on the other side. A braking mechanism corresponding to one of the rollers is provided inside the movable frame. A rotating rod is rotatably fitted inside the support plate, and a rotating groove is formed at the top of the support plate. A locking block is provided at one end of the rotating rod, and the locking block is located within the rotating groove. A locking groove corresponding to the rotating groove is formed at the bottom of the rotating column, and the locking block and the locking groove are engaged.

[0007] Furthermore, the support mechanism includes two support rods rotatably engaged on opposite outer sides of the support plate, and four support cylinders rotatably engaged on the top of the movable frame, with the four support rods slidably engaged within the four support cylinders.

[0008] Furthermore, the braking mechanism includes a brake lever rotatably engaged within the movable frame and a brake plate mounted on the brake lever, the brake plate corresponding to one of the rollers, and a pedal installed at one end of the brake lever that passes through the movable frame.

[0009] Furthermore, a pull rod is installed at one end of the rotating rod that passes through the support plate, a limiting ring is sleeved around the rotating rod, and a torsion spring is provided between one side of the limiting ring and one side of the support plate.

[0023] Reference Figure 2 The support mechanism 5 in this embodiment includes two support rods 15 rotatably engaged with the opposite outer sides of the support plate 4, and four support cylinders 16 rotatably engaged with the top of the movable frame 1. The four support rods 15 are slidably engaged within the four support cylinders 16. The support rods 15, slidably engaged within the support cylinders 16, allow the telescopic rods formed by the support rods 15 and support cylinders 16 to provide limiting support for the support plate 4. When the support plate 4 rises or falls, the support rods 15 slide within the support cylinders 16.

[0024] Reference Figure 2The braking mechanism 10 in this embodiment includes a brake rod 17 rotatably fitted within the movable frame 1 and a brake plate 18 mounted on the brake rod 17. The brake plate 18 corresponds to one of the rollers 2. A pedal 19 is installed at one end of the brake rod 17 that passes through the movable frame 1. By using the pedal 19, the operator can step on the pedal 19, causing the pedal 19 to rotate the brake rod 17. The rotation of the brake rod 17 will drive the brake plate 18, causing the brake plate 18 to come into contact with the roller 2, thereby braking and fixing the roller 2.

[0025] Reference Figure 3 In this embodiment, a pull rod 20 is installed at one end of the rotating rod 11 that passes through the support plate 4. A limiting ring 21 is sleeved around the rotating rod 11, and a torsion spring 22 is provided between one side of the limiting ring 21 and one side of the support plate 4. By pulling the pull rod 20, the rotating rod 11 can be rotated, causing the rotating rod 11 to move the locking block 13 out of the slot 14. At this time, the rotating column 6 can rotate. After the rotating column 6 rotates and resets, the slot 14 will correspond to the rotating groove 12. At this time, the torsion spring 22 will drive the rotating rod 11 to rotate through the limiting ring 21, causing the rotating rod 11 to drive the locking block 13 into the slot 14, automatically fixing the rotating column 6.

[0026] Reference Figure 3 In this embodiment, a fixing clip 23 is snapped onto the handle 9, and a storage box 24 is mounted on the top of the fixing clip 23. Through the fixing clip 23, the storage box 24 can be installed onto the handle 9, so that the storage box 24 can hold tools for use.

[0028] Working principle: In use, the height of the cushioned seat 7 can be adjusted by first rotating the lead screw 3. Rotating the lead screw 3 will cause it to rise or fall within the movable frame 1, thus driving the support plate 4. The support plate 4 is limited and supported by the support mechanism 5, causing the support plate 4 to rise or fall along with the lead screw 3. The movement of the support plate 4 will drive the cushioned seat 7 to rise or fall, adjusting the height of the cushioned seat 7. After adjusting it to a suitable height for the staff, the staff can sit on the cushioned seat 7. During this process, the backrest 8 can be rotated and adjusted. Then, the device can be moved, and the device will be moved via the rollers 2. The handle 9 allows for easy operation by staff, enabling the roller 2 to move back and forth along the narrow space between the strawberry rows. Once it reaches the desired left or right position, the braking mechanism 10 can be activated to fix one of the rollers 2, stopping the device from moving. Then, the rotating rod 11 can be rotated, causing the locking block 13 to move out of the slot 14, releasing the fixing of the rotating column 6. The cushioned seat 7 can then be rotated, causing the cushioned seat 7 to drive the rotating column 6 to rotate, allowing staff to rotate and adjust their orientation for work in the narrow space between the strawberry rows.

[0029] In another embodiment provided by this utility model, the following features are present:

[0030] The mobile frame 1 and rollers 2 are designed to be lightweight, reducing the physical exertion of operators and increasing work speed. The overall structure is compact and suitable for the narrow environment between strawberry rows. The rollers 2 are made of plastic, which can bear the weight while avoiding damage to the mulch film. The rollers 2 are also easy to clean after use. The design is durable and can adapt to the needs of multiple operations.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
