DETAILED DESCRIPTION

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] like Figure 1-Figure 7 The riding high-speed rice transplanter shown in the figure comprises a vehicle body 1, the rear end of the vehicle body 1 is connected with a lifting platform 2 in a vertical sliding manner, a contact plate 20 is fixedly installed on the lower surface of the lifting platform 2, and an inclined guide surface 21 is provided at the front edge of the contact plate 20, the rear end of the vehicle body 1 is connected with a connecting plate 5 through a lifting mechanism, a lifting plate 6 is fixedly connected at the front end of the lower surface of the connecting plate 5, guide columns 9 are fixedly connected on both sides of the lower surface of the lifting plate 6, an anti-slip edge 10 is provided at the lower edge of the outer surface of the guide column 9, a guide cylinder 7 is slidingly sleeved on the outer surface of the anti-slip edge 10, the lower end of the guide cylinder 7 is fixedly connected to the upper surface of the lifting platform 2, an adjusting column 12 is penetrated by the inner side thread of the guide column 9, a lifting disk 11 is fixedly connected to the lower end of the adjusting column 12, a compression spring 8 is provided between the lower surface of the lifting disk 11 and the inner bottom surface of the guide cylinder 7, a synchronization mechanism is commonly provided at the upper ends of the two adjusting columns 12, and a rice transplanting mechanism is provided at the rear end of the upper surface of the lifting platform 2.

[0026] A sleeve plate 18 is fixedly installed at the rear end of the vehicle body 1, and a vertical guide plate 17 is slidably penetrated through the outer surface of the sleeve plate 18. The lower end of the vertical guide plate 17 is fixedly connected to the upper surface of the lifting platform 2. A reinforcing rib 19 is fixedly connected to the upper end of the rear surface of the vertical guide plate 17, and the lower end of the reinforcing rib 19 is fixedly connected to the upper surface of the lifting platform 2. When the lifting platform 2 moves up and down, the vertical guide plate 17 will slide up and down relative to the sleeve plate 18, and the reinforcing rib 19 plays a role in increasing the structural strength to prevent the vertical guide plate 17 from structural deformation.

[0027] The lifting mechanism includes a mounting seat 3 fixedly mounted at the rear end of the vehicle body 1, a telescopic cylinder 4 is fixedly mounted on the upper end of the mounting seat 3, and the telescopic end of the telescopic cylinder 4 is fixedly connected to the lower surface of the connecting plate 5. When the telescopic cylinder 4 is extended and retracted, the connecting plate 5 can be moved up and down.

[0028] The synchronization mechanism includes a top wheel 13 fixedly connected to the upper end of the distance adjusting column 12, and a transmission tooth 15 is provided on the outer surface of the top wheel 13. A synchronous belt 16 is sleeved on the surfaces of the two top wheels 13, and the synchronous belt 16 is meshed with the transmission tooth 15. When the top wheel 13 on one side rotates, the synchronous belt 16 drives the top wheel 13 on the other side to rotate at the same time, thereby making the distance adjusting columns 12 on both sides move up and down synchronously for adjustment, so as to prevent the compression springs 8 on both sides from being squeezed to different degrees during adjustment.

[0029] A polygonal groove 14 is formed on the upper surface of the top wheel 13 , and can be formed as a common hexagonal groove, so as to facilitate the use of a wrench to rotate the top wheel 13 .

[0030] The rice transplanting mechanism comprises a seedling placing box 36 fixedly mounted in the middle of the upper surface of the lifting platform 2, and a seedling pulling mechanism is arranged at the rear end of the upper surface of the lifting platform 2. The seedling placing box 36 is a common technology, which is used to place the rice seedlings, and a through opening is provided on the lower surface to facilitate the cooperation with the seedling pulling mechanism to pull out the rice seedlings.

[0031] The seedling-moving mechanism includes two side plates 27 fixedly mounted on the upper surface of the lifting platform 2, a connecting shaft 35 is fixedly inserted between the two side plates 27, a transmission shaft 29 is rotatably inserted at the front end between the two side plates 27, a transmission rod 30 is fixedly sleeved at both ends of the transmission shaft 29, an L-shaped rod 31 is rotatably connected to the lower end of the side surface of the transmission rod 30 through a second rotating shaft 34, a connecting rod 33 is rotatably connected to the lower end of the side surface of the connecting rod 33 and the side surface of the L-shaped rod 31 through a first rotating shaft 32, and a driving mechanism is provided on the surface of the transmission shaft 29. When the transmission shaft 29 rotates, the transmission rod 30 will rotate, thereby driving the L-shaped rod 31 and the connecting rod 33 to move. At the same time, due to the existence of the first rotating shaft 32 and the second rotating shaft 34, the L-shaped rod 31 has a grasping action, so that the lower end of the L-shaped rod 31 grasps the seedlings at the seedling box 36 and performs a downward insertion action.

[0032] The driving mechanism includes a support frame 22 fixedly mounted on the upper surface of the lifting platform 2, a rotating shaft 23 is rotatably penetrated through the side surface of the support frame 22, a transmission gear 25 is fixedly sleeved on the outer surface of the rotating shaft 23, one end of the rotating shaft 23 is fixedly connected to the output shaft of the motor 24, the motor 24 is fixedly mounted on the side surface of the support frame 22, a gear sleeve 28 is fixedly sleeved on the outer surface of the transmission shaft 29, and a transmission chain 26 is sleeved on the outer sides of the transmission gear 25 and the gear sleeve 28. When the motor 24 rotates, the rotating shaft 23 rotates, and the power is transmitted to the transmission shaft 29 under the cooperation of the transmission gear 25, the transmission chain 26 and the gear sleeve 28.

[0033] During use, the lower surface of the contact plate 20 is always in contact with the ground, which has a smoothing effect to ensure the stability of subsequent transplanting and prevent it from tilting. At the same time, due to the existence of the inclined guide surface 21, when it contacts a stone, the inclined guide surface 21 can move upward relatively, driving the lifting platform 2 to move upward, and the guide cylinder 7 can slide upward relative to the guide column 9, squeezing the compression spring 8, thereby preventing the lower surface of the lifting platform 2 from being hard-scratched with stones, effectively avoiding damage, and is suitable for use in complex field conditions.

[0034] By controlling the extension and retraction of the telescopic cylinder 4, the connecting plate 5 moves up and down, and then the lifting plate 6 moves up and down, driving the guide column 9, the guide cylinder 7 and the lifting platform 2 to move up and down, changing the distance between the lifting platform 2 and the ground, ensuring the appropriate depth when transplanting rice seedlings, and also ensuring that no scratches or damage will occur when traveling on land. The use and adjustment are flexible and convenient.

[0035] By turning one of the top wheels 13 with the help of a wrench, the top wheel 13 on the other side will also rotate with the cooperation of the synchronous belt 16, so that the distance adjustment column 12 moves up and down relative to the guide column 9 to change its position, thereby changing the height of the lifting plate 11 and the degree of compression of the compression spring 8. Therefore, it is possible to adjust the pushing force required for the contact plate 20 to move upward, thereby preventing the compression spring 8 from being squeezed too low to cause instability during movement of the lifting platform 2, and also preventing the compression spring 8 from being squeezed too high to cause difficulty in lifting when hit by hard objects on the ground.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
