[0038] Rear axle assembly of rice transplanter 100,

[0039] 10 mainframe racks;

[0040] Mounting bracket 20, first frame 210, second frame 220

[0041] Rear axle 30, intermediate housing 310, mounting hole 311, pivot shaft 312, side drive housing 320.

[0042] First elastic component 410, first elastic element 411, second elastic element 412, second elastic component 420, first spring 421, second spring 422.

[0043] Pivoting assembly 50,

[0044] Fastener 60, first fixing block 610, second fixing block 620, pivot hole 601, assembly hole 602. Detailed Implementation

[0045] To further illustrate the technical means and effects of this utility model in order to achieve its intended purpose, the present utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0046] As shown in Figures 1 and 2, the rear axle assembly 100 of the rice transplanter according to an embodiment of the present invention includes: a main frame 10, a mounting frame 20, and a rear axle 30.

[0047] Specifically, as shown in Figure 3, one end of the mounting bracket 20 is connected to the main frame 10 via the first elastic component 410, and the other end of the mounting bracket 20 is connected to the main frame 10 via the pivot component 50. The rear axle 30 is mounted on the mounting bracket 20.

[0048] It should be noted that the mounting frame 20 is connected to the main frame 10 through the first elastic component 410 and the pivot component 50 to form an elastic linkage mechanism. When the rice transplanter encounters a bumpy road surface during its movement, the rear wheel mounted on the rear axle 30 can drive the rear axle 30 to move up and down relative to the main frame 10, thereby enabling the rice transplanter to have a good vibration reduction effect in the vertical direction.

[0049] As shown in Figures 3 and 4, a second elastic component 420 is provided between the rear axle 30 and the mounting frame 20. The rear axle 30 can be tilted relative to the horizontal plane via this second elastic component 420. It should be noted that by setting the second elastic component 420, when the rice transplanter travels on roads of varying depths, the two rear wheels mounted on the rear axle 30 can tilt left and right, keeping the upper frame 20 and the transplanting platform upright. This ensures the transplanting platform remains at the same horizontal and vertical level with the ground, solving the problems of seedling drift and excessively deep planting affecting seedling survival rates caused by a tilted transplanting platform, thus improving transplanting efficiency. For example, if there is a depression at the left rear wheel during the transplanter's movement, the left rear wheel will press against the second elastic component 420, tilting downwards, resulting in a tilted state with the left wheel lower and the right wheel higher, improving the transplanter's adaptability to uneven terrain.

[0050] According to the embodiment of the present utility model, the rear axle assembly 100 of the rice transplanter can not only float up and down to reduce vertical vibration when traveling on uneven paddy field terrain, but also swing left and right to make the transplanting platform pass through uneven terrain smoothly, maintain the consistency of transplanting depth, effectively avoid the problems of floating seedlings and transplanting too deep, thereby effectively ensuring the efficiency of rice transplanting and the survival rate of seedlings.

[0051] According to some embodiments of this utility model, as shown in Figure 3, the mounting frame 20 includes a first frame 210 and a second frame 220 spaced apart along the height direction of the rice transplanter. One end of each of the first frame 210 and the second frame 220 is connected to the main frame 10 via a pivot assembly 50. Thus, a deformable quadrilateral linkage mechanism is formed between the first frame 210, the second frame 220, the first elastic assembly 410, and the main frame 10. This effectively improves the vibration reduction effect and stability of the rice transplanter.

[0052] In some embodiments of this utility model, as shown in Figures 4-6, the rear axle assembly 100 of the rice transplanter further includes: a fixing member 60, which is mounted on the mounting frame 20 and has a pivot hole 601; the rear axle 30 has a pivot shaft 312, and the rear axle 30 is rotatably engaged with the fixing member 60 via the pivot shaft 312 and the pivot hole 601. It can be understood that through the above arrangement, the rear axle 30 can rotate relative to the mounting frame 20, thereby causing the two rear wheels to form an inclination angle with the horizontal plane. This allows the rice transplanter to smoothly pass over undulating roads while the two rear wheels are in an inclination state.

[0053] According to some embodiments of the present invention, as shown in FIG5, the fixing member 60 includes: a first fixing block 610 and a second fixing block 620, wherein the first fixing block 610 and the second fixing block 620 are provided with opposing pivot holes 601. In some embodiments of the present invention, the first fixing block 610 and the second fixing block 620 are connected and have mounting holes 602 perpendicular to the direction of the pivot holes 601.

[0054] As shown in Figures 5 and 6, after the rear axle 30 is assembled with the fixing member 60, the pivot shaft 312 of the rear axle 30 is rotatably engaged with the pivot hole 601 of the fixing member 60, and the rear axle 30 extends out from the mounting holes 602 on both sides of the fixing member 60. The size of the mounting holes 602 can limit the rotation range of the rear axle 30, thereby effectively avoiding the problem of excessive rotation of the rear axle 30 causing interference with other structures or the risk of rollover.

[0055] In some other embodiments of this utility model, as shown in Figures 7-9, the first fixing block 610 and the second fixing block 620 are spaced apart along the traveling direction of the rice transplanter. This simplifies the structure of the fixing member 60 and facilitates its installation with the rear axle 30 and the mounting frame 20. As shown in Figure 9, the first fixing block 610 and the second fixing block 620 can be configured as a triangular structure with rounded corners, thereby improving structural strength and stability.

[0056] In some embodiments of this utility model, as shown in Figures 1 and 3, the first elastic component 410 includes a first elastic element 411 and a second elastic element 412 symmetrically arranged. The first ends of both the first elastic element 411 and the second elastic element 412 abut against the main frame 10, and the second ends of both the second elastic elements 412 abut against the mounting frame 20. It can be understood that by symmetrically arranging the first elastic element 411 and the second elastic element 412 in the left-right direction, the stability of the rice transplanter's movement can be further improved.

[0057] According to some embodiments of this utility model, as shown in Figures 3 and 4, the rear axle 30 has two symmetrically arranged mounting holes 311. The second elastic component 420 includes a first spring 421 and a second spring 422. The first ends of the first spring 421 and the second spring 422 are disposed in the corresponding mounting holes 311, and the second ends of the first spring 421 and the second spring 422 abut against the mounting bracket 20. It should be noted that, due to uneven ground, the left and right rear wheels may randomly experience ups and downs. Therefore, the first spring 421 and the second spring 422 are arranged on the left and right sides of the rear axle 30 to effectively cope with different terrain conditions. After passing over uneven ground, the first spring 421 or the second spring 422, under the action of elastic restoring force, restores the rear axle 30 to a horizontal state.

[0058] In some embodiments of this utility model, as shown in FIG4, the rear axle 30 includes: a middle housing 310 and two side transmission housings 320, mounting holes 311 are spaced apart along the length direction of the middle housing 310, and the two side transmission housings 320 are symmetrically connected to the two ends of the middle housing 310.

[0059] The rice transplanter according to an embodiment of the present utility model includes: a rear axle assembly, wherein the rear axle assembly adopts the rice transplanter rear axle assembly 100 as described above.

[0060] The rice transplanter according to the present invention has a rear axle assembly that can adapt well to uneven paddy field terrain, thereby maintaining a consistent transplanting depth and effectively ensuring transplanting efficiency and seedling survival rate.
