[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] See also Figure 1-5: In this embodiment, a flat wheel that is easy to install includes a straight rod 1 and a bracket 4. The front of the outer wall of the straight rod 1 is rotatably connected to the inner wall of the bracket 4. The straight rod 1 is subjected to force and rotates through the bearing on the inner wall of the bracket 4. A flat wheel 5 is fixedly connected to the rear of the outer wall of the straight rod 1. The upper and lower side grooves of the bracket 4 are respectively connected to the mounting structure 2. The front of the flat wheel 5 is connected to the supporting structure 3. The left side of the supporting structure 3 is fixedly connected to the right side of the bracket 4. A rice transplanter bracket 7 is inserted into the outer wall of the bracket 4, and the outer wall of the rice transplanter bracket 7 is inserted into the outer side of the mounting structure 2.

[0022] The mounting structure 2 comprises a bent plate 201 and a vertical rod 202. The outer walls of the two bent plates 201 are respectively fitted with the notches on the upper and lower sides of the bracket 4. The bent plate 201 is subjected to force and moves up and down through the inner walls of the notches on the upper and lower sides of the bracket 4. The inner side of the bent plate 201 is fixedly connected to the outer side of the vertical rod 202. The outer wall of the vertical rod 202 is sleeved with a spring 203. The two ends of the spring 203 are respectively fixedly connected to the outer wall notches of the bracket 4 and the inner side of the bent plate 201. After the bent plate 201 is forced to move inward, it rebounds through the elastic force of the spring 203. The outer side of the bent plate 201 is plugged into the outer wall of the transplanter bracket 7. The outer ends of the two bent plates 201 are respectively fixedly connected with curved blocks, which are rubber blocks that protect the hands that install the bent plates 201.

[0023] By using the installation structure 2 to squeeze the bent plates 201 on the upper and lower sides of the bracket 4 inward, the bent plates 201 move inward with the vertical rods 202, and at the same time the bent plates 201 squeeze the springs 203 until the outer side of the bent plates 201 is flush with the outer wall of the bracket 4, and then the bracket 4 is plugged into the inner wall of the rice transplanter bracket 7, and then the bent plates 201 are released, the springs 203 lose pressure and provide a rebound force, so that the bent plates 201 move outward, and the inner wall of the bent plates 201 is plugged into the rice transplanter bracket 7, completing the installation of the leveling wheel, facilitating the installation of the leveling wheel and the rice transplanter, and improving the installation efficiency of the leveling wheel.

[0024] The supporting structure 3 includes a circular frame 301 and a cylinder 302. The rear end face of the circular frame 301 is fixedly connected to the front face of the leveling wheel 5. The inner wall of the circular frame 301 fits with the outer wall of the cylinder 302. The inner wall of the cylinder 302 is rotatably connected to a bent rod 303. The cylinder 302 is rotated by the outer wall bearing of the bent plate 303. The left end of the bent rod 303 is fixedly connected to the right side of the bracket 4.

[0025] Working principle:

[0026] Flat wheel installation:

[0027] The bent plates 201 on the upper and lower sides of the bracket 4 are squeezed inward. At this time, the bent plates 201 move inward with the vertical rods 202. At the same time, the bent plates 201 squeeze the springs 203 until the outer side of the bent plates 201 is flush with the outer wall of the bracket 4. Then the bracket 4 is plugged into the inner wall of the transplanter bracket 7. Then the bent plates 201 are released. The springs 203 lose pressure and provide a rebound force, causing the bent plates 201 to move outward. The inner wall of the bent plates 201 is plugged into the transplanter bracket 7 to complete the installation of the leveling wheels.

[0028] Flat wheel reinforcement support:

[0029] During the rotation of the flat wheel 5, the round frame 301 on the front side of the flat wheel 5 will rotate on the outer wall of the cylinder 302. The cylinder 302 is connected to the outer wall of the curved rod 303 in rotation, and no friction is generated between the cylinder 302 and the round frame 301. The curved rod 303 cooperates with the cylinder 302 to support the round frame 301. In addition, the round frame 301 is integrated with the flat wheel 5 to support the flat wheel 5.

[0030] Embodiment 2:

[0031] See also Figure 1-5 In the present embodiment, a flat wheel that is easy to install further includes a top plate 6, and the inner sides of the two top plates 6 are fixedly connected to the upper left and right sides of the bracket 4 respectively.

[0032] Working principle:

[0033] The support of the bracket 4 can be achieved by placing the hand on the bottom of the top plate 6 or holding the top plate 6 , so that the position of the bracket 4 can be adjusted when the leveling wheel 5 is installed.

[0034] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
