Description

Technical Field

[0001] This utility model relates to the field of crop cultivation, and in particular to a tobacco seedling transplanting vehicle. Background Technology

[0002] In the process of flue-cured tobacco cultivation, seedlings are first raised in a greenhouse. Once the seedlings have grown, ridges are prepared in the field, and the seedlings are then transplanted into these ridges outside the greenhouse. Transplanting seedlings requires frequent handling, resulting in high labor intensity and low efficiency. Because of the ridges, transport vehicles that normally travel on roads cannot move through the fields. While wheelbarrows can travel between ridges, they are particularly prone to tipping over and damaging the seedlings. Summary of the Invention

[0003] This invention solves the problem of low transplanting efficiency caused by relying solely on manual labor to transport tobacco seedlings when there is no suitable transplanting vehicle.

[0004] The tobacco seedling transplanter of this utility model includes a support frame for carrying tobacco seedling trays, two front support legs located at the front end of the support frame for supporting the front end of the support frame, and two rear support legs located at the rear end of the support frame for supporting the rear end of the support frame. The distance L1 between the two front support legs and the distance L2 between the two rear support legs are both 115cm-125cm. The two rear support legs are each equipped with a walking wheel that can walk on the ground. The tobacco seedling transplanter also includes a movable frame located at the front end of the support frame for pushing or pulling the transplanter.

[0020] Figure 1The image shows a tobacco seedling transplanter according to an embodiment of the present invention. It includes a support frame 1 for carrying a tobacco seedling tray (not shown), two front support legs 2 located at the front end of the support frame 1 to support the front end of the support frame 1, and two rear support legs 3 located at the rear end of the support frame 1 to support the rear end of the support frame 1. The distance L1 between the two front support legs 2 and the distance L2 between the two rear support legs 3 are both 115cm-125cm, such that the two front support legs 2 are exactly on both sides of the soil ridge, and the two rear support legs 3 are exactly on both sides of the soil ridge. In this embodiment, L1 = L2 = 120cm. The two rear support legs 3 are each equipped with a walking wheel 5 that can travel on the ground. The tobacco seedling transplanter also includes a movable frame 4 located at the front end of the support frame 1 for pushing or pulling the transplanter.

[0021] When using this utility model of a tobacco seedling transplanter, its two front support legs 2 are positioned on both sides of the ridge, and its two rear support legs 3 are positioned on both sides of the ridge. By lifting the moving frame 4 upwards and pushing or pulling the transplanter, the entire transplanter can be moved along the soil ridge. The carrier frame 1, which carries the tobacco seedling tray, passes over the soil ridge and the transplanted tobacco seedlings, thus conveniently and labor-savingly transporting the trays containing the tobacco seedlings. This improves the efficiency of transplanting and does not damage the shape of the soil ridge or the transplanted tobacco seedlings.

[0022] like Figure 1 As shown, the support frame 1 includes a rectangular frame 11, which is welded from metal tubes. The support frame 1 also includes a horizontal tube 12 extending laterally (left-right) within the frame 11. In this embodiment, the metal tube is a square tube. In this embodiment, the front support leg 2 and the rear support leg 3 are each composed of a square tube.

[0023] In another embodiment, such as Figure 2As shown, both the front support leg 2 and the rear support leg 3 include upper pipe sections 21 and 31 and lower pipe sections 22 and 32. The upper pipe sections 21 and 31 and the lower pipe sections 22 and 32 are all square tubes. The upper ends of the upper pipe sections 21 and 31 are fixedly connected to the support frame 1. The upper ends of the lower pipe sections 22 and 32 are inserted into the lower ends of the upper pipe sections 21 and 31. The upper pipe sections 21 and 31 can be inserted into the lower pipe sections 22 and 32, or the lower pipe sections 22 and 32 can be inserted into the upper pipe sections 21 and 31. The lower ends of the upper pipe sections 21 and 31 of the front support leg 2 and the rear support leg 3 are provided with multiple adjustment holes 211 and 311, and the upper ends of the lower pipe sections 22 and 32 of the front support leg 2 and the rear support leg 3 are provided with multiple adjustment holes 221 and 321. The axes of the adjustment holes 211, 311, 221 and 321 are perpendicular to the length direction of the upper and lower pipe sections. The front support leg 2 and the rear support leg 3 also include an adjustment bolt 23 that can pass through the adjustment holes 211 and 311 of the upper pipe section 21 and 31 and the adjustment holes 221 and 321 of the lower pipe section 22 and 32, and an adjustment nut (not shown in the figure) that mates with the end of the adjustment bolt 23 and the adjustment bolt 23. By changing the adjustment holes 211, 311, 221 and 321 through which the adjustment bolts 23 and 33 pass, the length of the front support leg 2 and the rear support leg 3 can be changed, thereby adapting to different soil ridge heights and tobacco seedling heights.

[0024] like Figure 1 As shown, the front end of the support frame 1 has connecting rods 13 extending forward on both sides. The movable frame 4 includes a horizontal bar 41 perpendicular to the front-rear direction of the support frame 1 and two vertical bars 42 located at both ends of the horizontal bar 41, perpendicular to and fixed to the horizontal bar 41. The two vertical bars 42 are fixedly connected to the two connecting rods 13 one-to-one. In this embodiment, the vertical bars 42 are fixed to the connecting rods 13 by welding. The vertical bars 42 can be perpendicular to the support frame 1 or inclined relative to the support frame 1.

[0025] In another embodiment (not shown in the figure), the connecting rod 13 and the vertical rod 42 are provided with mounting holes. The tobacco seedling transplanter also includes a connecting device, which includes a fastening bolt and a nut. One end of the fastening bolt passes through the mounting hole of the vertical rod 42 and the mounting hole of the connecting rod 13, and then cooperates with the nut to fix the connecting rod 13 and the vertical rod 42 together. With this structure, the angle of the vertical rod 42 relative to the connecting rod 13 can be adjusted. After adjusting the angle, tightening the fastening bolt and nut allows for adjustment of the height of the horizontal rod 41, accommodating people of different heights to move the tobacco seedling transplanter.

[0026] like Figure 1As shown, the tobacco seedling transplanter is also equipped with a reinforcing rod 6. One end of the reinforcing rod 6 is fixedly connected to the rear support leg 3, and the other end is fixedly connected to the bearing frame 1. The reinforcing rod 6 is inclined relative to the plane where the bearing frame 1 is located, which can strengthen the connection between the rear support leg 3 and the bearing frame 1, making its overall structure more stable.

[0027] The distance H1 between the lowest point of the front support leg 2 and the support frame 1 is 5cm-10cm smaller than the distance H2 between the lowest point of the walking wheel 5 and the support frame 1. When moving the tobacco seedling transplanter, the front support leg 2 needs to be lifted off the ground by the moving frame 4. The difference between H1 and H2 allows the front support leg 2 to move normally without being lifted very high, and also ensures that the support frame 1 does not tilt too much when the tobacco seedling transplanter is on the ground. In this embodiment, H1 is 5cm smaller than H2.

[0028] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art within the spirit and scope of this utility model also fall within the scope of protection of this utility model.
