Description

Technical Field

[0001] This utility model relates to the field of rice transplanters, specifically a shock-absorbing mechanism for the soil-sealing wheel of a rice transplanter. Background Technology

[0002] The following defects may exist in existing products on the market:

[0003] 1. Inconvenient height adjustment:

[0004] The lack of a flexible height adjustment mechanism in existing rice transplanters makes them unable to adapt to soil conditions at different heights, affecting their versatility and flexibility.

[0005] The adjustment process is cumbersome and laborious, reducing operational efficiency.

[0006] 2. The spacing between the sealing wheels is limited:

[0007] The existing rice transplanter's soil-sealing wheel assembly cannot easily adjust the spacing, making it unable to adapt to the soil-sealing requirements of different crops.

[0008] An unreasonable design of the regulating mechanism can lead to difficulties or instability in regulation.

[0009] Therefore, we propose a shock-absorbing mechanism for the soil-sealing wheel of a rice transplanter to solve the above problems. Utility Model Content

[0010] To solve the above-mentioned technical problems, this utility model provides a shock-absorbing mechanism for the soil sealing wheel of a rice transplanter.

[0011] This utility model provides a soil-sealing wheel shock absorption mechanism for a rice transplanter, including a frame. Vertical sleeves are fixed at each of the four corners of the frame. A lead screw is rotatably connected to each vertical sleeve via bearings. Vertical connecting rods are slidably connected within each sleeve, and threaded holes are provided within each vertical connecting rod. The lead screw and threaded holes are connected by threads. Front wheels are installed at the front ends of the two vertical connecting rods on the front side of the frame, and rear wheels are installed at the bottom ends of the two vertical connecting rods on the rear side of the frame. Vertical poles are symmetrically fixed to the rear side of the frame, and connecting rods are hinged to the bottom ends of the vertical poles. Two connecting rods... A mounting rod is fixedly connected to the main structure. An ear plate is fixed to the connecting rod. A rotating rod is hinged to the ear plate via a pivot. A fixing rod is fixed to the main structure. One end of the fixing rod is integrally provided with a flat plate. The flat plate has a mounting hole. The end of the rotating rod away from the pivot passes through the mounting hole. The diameter of the rotating rod is larger than the diameter of the mounting hole. A compression spring is sleeved on the outside of the main structure. The two ends of the compression spring contact the flat plate and the end of the rotating rod, respectively. A pin hole is provided on the rotating rod. A retaining spring is engaged in the pin hole. Two sealing wheel assemblies are mounted on the mounting rod.

[0012] Because the soil height varies at different locations, the sealing wheel contacts the soil at different locations. Due to the presence of the compression spring and the upright, the connecting rod, mounting rod, and sealing wheel assembly swing up and down together along the bottom of the upright, making it suitable for soils of different heights.

[0013] A retaining ring is fitted on the outer side of the rotating rod. The two sides of the retaining ring contact the retaining spring and the plate respectively, so as to avoid direct friction between the retaining spring and the plate.

[0014] Preferably, the sealing wheel assembly includes two cooperating sealing wheels and a mounting frame for connecting the sealing wheels and the mounting rod. One end of the mounting frame is sleeved on the mounting rod, and the mounting frame is provided with screw holes. Screws for fixing the mounting rod and the mounting frame are installed in the screw holes, and the sealing wheels are rotatably connected to the other end of the mounting frame.

[0015] By adjusting and loosening the screws, moving the mounting bracket, and then retightening the screws, the distance between the two sealing wheels can be adjusted to suit the sealing of different crops.

[0016] An electric motor is installed on the vertical connecting rod at the front of the frame. The output shaft of the electric motor is fixedly connected to the front wheel. The electric motor drives the front wheel to rotate, thereby causing the rice transplanter to move forward.

[0017] A drive arm is fixed to the top of the lead screw, and the lever principle makes it easier to drive the lead screw.

[0018] The drive arm has a through hole for easy insertion of tools, which makes it easier to rotate the lead screw.

[0019] Compared with related technologies, the present invention provides the following beneficial effects:

[0020] 1. High adaptability:

[0021] By adjusting the threaded connection between the lead screw and the vertical connecting rod, the height of the frame and the entire rice transplanter can be easily adjusted, making it adaptable to soil environments of different heights and improving the versatility and flexibility of the rice transplanter.

[0022] The design of the sealing wheel assembly also allows for adjustment of the spacing between the sealing wheels by adjusting the position of the mounting bracket on the mounting rod, thus adapting to the sealing needs of different crops.

[0023] 2. Excellent shock absorption performance:

[0024] The compression spring effectively absorbs the vibration generated when the sealing wheel comes into contact with the soil, protecting other parts of the rice transplanter from damage and improving operator comfort.

[0025] The design of the connecting rod, mounting rod, and soil sealing wheel assembly swinging up and down along the bottom of the upright further enhances the shock absorption effect, enabling the rice transplanter to maintain stable operation even on uneven fields. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] Please refer to the following: Figures 1 to 4 A soil-sealing wheel shock-absorbing mechanism for a rice transplanter is disclosed, featuring an ingenious structural design designed to adapt to different soil heights and ensure effective soil sealing. The mechanism mainly comprises a frame 1, with vertical sleeves 2 securely fixed at each of its four corners. Inside these vertical sleeves 2, a lead screw 3 is cleverly connected via bearings, allowing for smooth rotation of the lead screw. Simultaneously, vertical connecting rods 4 are slidably connected within the sleeves 2. These connecting rods have specially designed threaded holes that tightly engage with the lead screw 3 via threads, allowing the height of the connecting rods to be adjusted by rotating the lead screw.

[0034] Front wheels 5 are cleverly installed at the front ends of the two vertical connecting rods 4 on the front side of the frame 1, providing forward power for the rice transplanter. Rear wheels 6 are installed at the bottom ends of the two vertical connecting rods 4 on the rear side of the frame, ensuring stable machine operation. Notably, uprights 7 are symmetrically fixedly connected to the rear side of the frame 1. The bottom ends of these uprights are hinged to connecting rods 8, and the two connecting rods together are fixedly connected to a mounting rod 9, which supports the soil-sealing wheel assembly.

[0035] A lug plate 10 is fixed to the connecting rod 8, and a rotating rod 11 is flexibly hinged to the lug plate via a pivot. Meanwhile, a fixing rod 12 is also fixed to the upright rod 7, one end of which extends integrally into a flat plate 13 with a mounting hole. The end of the rotating rod 11 furthest from the pivot passes cleverly through this mounting hole. Notably, the diameter of the rotating rod is slightly larger than the diameter of the mounting hole, ensuring a stable connection while allowing for a certain degree of sway. To enhance shock absorption, a compression spring 14 is fitted onto the outside of the upright rod 7, with its two ends in close contact with the ends of the flat plate 13 and the rotating rod 11, respectively, providing good cushioning.

[0036] To prevent direct friction between the retaining ring 15 and the plate 13, a retaining ring 16 is cleverly fitted onto the outer side of the rotating rod 11. The two sides of the retaining ring contact the retaining ring and the plate respectively, providing protection. In addition, the rotating rod 11 is also provided with a pin hole, in which the retaining ring 15 is engaged, ensuring the stable position of the rotating rod.

[0037] The sealing wheel assembly consists of two mating sealing wheels 17 and a mounting frame 18 for connecting the sealing wheels to the mounting rod 9. One end of the mounting frame 18 is flexibly fitted onto the mounting rod 9 and fixed by screws 19 in screw holes, allowing the mounting frame to slide along the mounting rod and be fixed in different positions, thereby adjusting the distance between the two sealing wheels according to crop requirements. The sealing wheels are rotatably connected to the other end of the mounting frame to ensure smooth sealing operations.

[0038] To provide forward propulsion, an electric motor 20 is installed on the vertical connecting rod 4 at the front of the frame 1. Its output shaft is fixedly connected to the front wheel 5. Driven by the electric motor, the rice transplanter can move forward easily. To facilitate the adjustment of the height of the lead screw 3, a drive arm 21 is fixed to the top of the lead screw, making adjustment easier by utilizing the lever principle. A through hole is also provided on the drive arm for easy insertion of tools, further simplifying the adjustment process and allowing the operator to more easily rotate the lead screw to adjust the height of the machine to adapt to different soil conditions.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
