Two groups of folding brackets 4 are symmetrically installed on the base plate 3, and a mounting top plate 5 is installed on the head of the folding bracket 4. The mounting top plate 5 has the same structure as the base plate 3. When in use, the mounting top plate 5 is flipped over and arranged opposite to the base plate 3, and then the two are connected to each other through the folding bracket 4. The folding bracket 4 comprises a first bendable frame 41 and a second bendable frame 42, and the two ends of the first bendable frame 41 are rotatably connected to the base plate 3 and the mounting top plate 5 respectively, and the two ends of the second bendable frame 42 are slidably connected to the base plate 3 and the mounting top plate 5 respectively. The upper end face of the base plate 3 is fixedly mounted with a driving member 6 for adjusting the position of the lower end of the second bendable frame 42. By symmetrically installing motor wheels 2 on both sides of the wheel seat 1, it is convenient to use the motor wheels 2 at both ends as a driving mechanism to perform driving operations. At the same time, by fixing the machine base plate 3 on the upper end face of the wheel seat 1, and then symmetrically installing two sets of folding brackets 4 through the machine base plate 3, the folding brackets 4 can be used to stably support the installation of the top plate 5, ensuring that the installation of the top plate 5 can be used as a support for the rice transplanter equipment. During use, the height of the equipment can be changed by adjusting the height of the installation top plate 5, and the setting of the driving member 6 can ensure that the position of the second foldable frame 42 can be flexibly adjusted, ensuring that the driving installation top plate 5 can be raised and lowered by adjusting the angle between the first foldable frame 41 and the second foldable frame 42.

[0028] Reference Figure 1 and Figure 2 As shown, the wheel seat 1 includes a horizontal base plate 11 and side plates 12. The side plates 12 are mounted at both ends of the horizontal base plate 11 and are fixedly connected to the horizontal base plate 11. The structural arrangement of the wheel seat 1 ensures that the side plates 12 can be fixedly mounted on both sides of the horizontal base plate 11 during use, so that the motor wheel 2 can be installed through the side plates 12. Vertical tube seats 13 are fixedly mounted on the four corners of the upper end surface of the horizontal base plate 11. A bracket 131 supporting the machine base plate 3 is mounted on the vertical tube seat 13. The bracket 131 is slidably connected to the vertical tube seat 13, and a support spring 132 supporting the bracket 131 is installed in the vertical tube seat 13. The arrangement of the vertical tube seat 13 and the bracket 131 ensures stable support for the machine base plate 3, and the arrangement of the support spring 132 ensures that a certain buffering effect can be achieved during the process of supporting the machine base plate 3.

[0029] Reference Figure 1 and Figure 3As shown, the motor wheel 2 includes a brushless motor 21 and an external tire 22. The brushless motor 21 is fixedly mounted on the outer surface of the side plate 12, and the external tire 22 is sleeved and fixed on the brushless motor 21. By designing the motor wheel 2 as a structure in which the brushless motor 21 and the external tire 22 cooperate, the brushless motor 21 can be used to drive the external tire 22 to rotate, thereby achieving the purpose of driving the device to move.

[0030] Reference Figure 4 and Figure 5 As shown, the machine base plate 3 includes a main plate portion 31, a rotating seat 32 for rotatably mounting the first bendable frame 41, and a slide 33 for slidably mounting the second bendable frame 42. The rotating seat 32 and the slide 33 are each provided in two sets, and the two sets of rotating seats 32 and the two sets of slides 33 are fixedly mounted on both sides of the upper end surface of the main plate portion 31. By designing the machine base plate 3 into a structure in which the main plate portion 31, the rotating seat 32, and the slide 33 cooperate, the first bendable frame 41 and the second bendable frame 42 can be respectively mounted via the rotating seat 32 and the slide 33 on the main plate portion 31 when convenient to use. When adjustment is required, the position of the second bendable frame 42 on the slide 33 can be slid to change the flip angle of the first bendable frame 41, thereby changing the support height of the folding bracket 4. The second bendable frame 42 includes a first support plate 421, a second support plate 422, and a connector 423. One end of the first support plate 421 is rotatably connected to one end of the second support plate 422, and the connector 423 is rotatably mounted on the other ends of the first support plate 421 and the second support plate 422. By designing the second bendable frame 42 as a structure in which the first support plate 421, the second support plate 422, and two sets of connectors 423 cooperate, it is convenient for the middle portions of the first support plate 421 and the second support plate 422 to be rotatably connected to the first bendable frame 41 when needed. In this way, when the bending angle between the first support plate 421 and the second support plate 422 is adjusted via the connector 423, the first bendable frame 41 can be driven to adjust synchronously.

[0031] Reference Figure 1 and Figure 4 As shown, the driving member 6 includes a hydraulic cylinder 61 and a horizontal push frame 62, which are fixedly mounted on the upper end surface of the main plate portion 31. The middle portion of the horizontal push frame 62 is connected to the output end of the hydraulic cylinder 61, and the two ends of the horizontal push frame 62 are fixed to the connector 423. By designing the driving member 6 as a structure in which the hydraulic cylinder 61 and the horizontal push frame 62 cooperate, it is easy to use when the hydraulic cylinder 61 can push the horizontal push frame 62 to move, and the horizontal push frame 62 can then drive the connectors 423 at both ends to move synchronously.

[0032] In this embodiment, during actual use, the motor wheels at both ends of the wheel seat can be used as a driving structure to drive the transplanter to move stably. When the equipment height needs to be adjusted during the transplanting process, the operator can control the hydraulic cylinder to push the horizontal push frame to move, ensuring that the horizontal push frame drives the connecting heads at both ends to move on the slide, thereby realizing the folding bracket to be unfolded or folded for use. In this way, the support height of the folding bracket can be adjusted to achieve the purpose of changing the height of the installation top plate.

[0033] The above is a preferred embodiment of the present invention. Technicians in the field of the present invention can also change and modify the above embodiment. Therefore, the present invention is not limited to the above specific embodiment. Any obvious improvements, replacements or modifications made by technicians in this field on the basis of the present invention are within the scope of protection of the present invention.
