[0002] The flat wheels drive the entire equipment to move along the field and align the position where rice seedlings need to be planted, so that the rice seedling planting operation can be carried out quickly and efficiently.

[0003] For example, a rice transplanter flat wheel transmission mechanism with the authorization announcement number "CN214902110U" has the other end of the flat wheel driving shaft connected to one end of the transition connecting shaft, the transition connecting shaft is assembled and installed at the bottom of the rear axle through a bearing seat, and the other end of the transition connecting shaft is connected to the flat wheel device through a spiral output shaft. The utility model incorporates the driving system of the flat wheel into the fertilization transmission system, eliminating a transmission gearbox, reducing costs, and reducing the load of the entire machine. The power of the flat wheel is directly transmitted from the gearbox through the transmission box, and the transmission efficiency is high, which reduces other influencing factors during the operation process. However, when the rice transplanter is in use, the flat wheel can only level the route after passing through, and cannot level the route in advance. Therefore, the flat wheel will contact the uneven mud surface during driving, which will increase the bumps of the rice transplanter and make the rice transplanter have an uneven body position, reduce the stability of the flat wheel walking, and affect the transplanting effect of the rice transplanter. Utility Model Content

[0011] Preferably, the inner walls of the first square plate and the second square plate are both processed with threaded openings.

[0012] The utility model provides a liftable leveling wheel, which has the beneficial effect of holding a handle in the lifting structure and rotating it, so that the handle rotates the circular plate, thereby causing the bottom screw to rotate downward through the top plate, and the rotating screw drives the push plate to move downward, so that the position of the push plate and the mud surface are inserted deeper, and the screw can be rotated in the opposite direction to move the push plate upward, thereby realizing the lifting and lowering of the push plate of the leveling wheel.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] See also Figure 1-6 : In this embodiment, a liftable flat wheel includes a horizontal plate 1 and a round rod 4. The inner walls of the two horizontal plates 1 are rotatably connected to the outer walls of the round rod 4 on both sides. The round rod 4 is rotated by the force through the bearings on the inner walls of the horizontal plates 1. The outer wall of the round rod 4 is fixedly connected to the flat wheel 5. The left end of the inner top of the horizontal plate 1 is connected to the lifting structure 2. The outer sides of the two horizontal plates 1 are respectively connected to the reinforcement structures 3. The right sides of the two horizontal plates 1 are fixedly connected to the second square plate 6. The outer wall of the lifting structure 2 is in contact with the inner wall of the horizontal plate 1.

[0023] The lifting structure 2 includes a top plate 201 and a screw rod 202. The front and rear ends of the top plate 201 are respectively fixed to the inner top left end of the horizontal plate 1. The inner wall of the top plate 201 is threadedly connected to the outer wall of the screw rod 202. The screw rod 202 is subjected to force to rotate up and down through the inner wall of the top plate 201. The outer wall of the screw rod 202 is rotatably connected to a push plate 203 at the bottom. A circular plate 205 is fixed to the top of the screw rod 202. The circular plate 205 can make the screw rod 202 rotate. The front and rear sides of the top of the push plate 203 are respectively fixed to vertical plates 204. The outer wall of the vertical plate 204 fits the inner wall of the horizontal plate 1. The vertical plate 204 is subjected to force to move up and down through the inner wall of the horizontal plate 1. A handle 206 is fixed to the left side of the top of the circular plate 205. The handle 206 is convenient for driving the circular plate 205 to rotate.

[0024] By holding the handle 206 in the lifting structure 2 and rotating it, the handle 206 rotates the circular plate 205, so that the bottom screw 202 rotates downward through the top plate 201, and the rotating screw 202 moves the push plate 203 downward, so that the position of the push plate 203 and the mud surface are inserted deeper, and the screw 202 is rotated in the opposite direction to move the push plate 203 upward, thereby realizing the lifting and lowering of the push plate 203 of the flat wheel 5. During the lifting process of the push plate 203, the vertical plate 204 moves up and down on the inner wall of the horizontal plate 1 with the push plate 203, and the vertical plate 204 limits the push plate 203, thereby improving the walking stability of the flat wheel and ensuring the transplanting effect of the rice transplanter.

[0025] The reinforcement structure 3 includes a slot plate 301 and a bent rod 302. The outer wall of the slot plate 301 is fixedly connected to the outer wall slot of the cross plate 1. The inner ends of the bent rod 302 of the slot plate 301 are plugged in. The bent rod 302 can move left and right on the inner wall of the slot plate 301 under force, and can rotate at an angle on the inner wall of the slot plate 301. The top of the outer wall of the bent rod 302 is rotatably connected to the first square plate 303. The first square plate 303 is rotated by the pin at the top of the outer wall of the bent rod 302 under force. The inner walls of the first square plate 303 and the second square plate 6 are both processed with threaded openings.

[0026] Working principle:

[0027] Flat wheel installation:

[0028] Make the second square plate 6 on the right side of the horizontal plate 1 fit with the connection of the rice transplanter, then the bolt is threaded through the second square plate 6 from left to right to connect with the rice transplanter, then the inner end of the bent rod 302 slides left and right on the inner wall of the groove plate 301, and at the same time the bent rod 303 rotates up and down at an angle, and the second square plate 303 rotates at an angle at the top of the outer wall of the bent rod 302, so that the right side of the first square plate 303 can fit with the connection of the rice transplanter, and then the bolt is threaded through the first square plate 303 from left to right to fix it to the rice transplanter.

[0029] Flat wheel use:

[0030] After the flat wheel 5 is installed, the rice transplanter works to make the flat wheel cooperate with the round rod 4 to rotate on the inner wall of the horizontal plate 1, and the rotating flat wheel 5 realizes position movement, and the round rod 4 moves with the horizontal plate 1, and the horizontal plate 1 moves with the lifting structure 2. At this time, the push plate 203 in the lifting structure 2 will push the mud surface passed by, so that the uneven mud surface can be leveled, and the mud surface can be leveled before the flat wheel 5 passes. Hold the handle 206 and rotate it. The handle 206 rotates the circular plate 205, so that the bottom screw 202 rotates downward through the top plate 201, and the rotating screw 202 moves the push plate 203 downward, so that the position of the push plate 203 and the mud surface are inserted deeper, and the screw 202 is rotated in the opposite direction to make the push plate 203 move upward, so that the push plate 203 of the flat wheel 5 can be lifted and lowered. During the lifting process of the push plate 203, the vertical plate 204 moves up and down on the inner wall of the horizontal plate 1, and the vertical plate 204 restricts the push plate 203.

[0031] Embodiment 2:

[0032] See also Figure 1-6 : In this embodiment, a liftable flat wheel also includes a gear 7, and the rear end surface of the gear 7 is fixedly connected to the front surface of the round rod 4.

[0033] Working principle:

[0034] The outer wall of the gear 7 can be meshed and connected with the transmission gear on the rice transplanter, and the transmission gear drives the gear 7 to rotate the round rod 4, and the round rod 4 drives the flat wheel 5 to rotate, thereby improving the rotation strength of the flat wheel 5.
