[0014] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, the braking linkage mechanism of this high-speed rice transplanter for hilly terrain includes a brake pedal 1 and a brake mechanism 2, with the brake pedal 1 driving the brake mechanism 2. It should be noted that... Figure 1 Only a portion of the structure of brake mechanism 2 is shown in the image.

[0016] A driven pulley 8 is provided on the side of the hydraulic continuously variable transmission 15, and an HST transmission rocker arm 13 is provided on its top.

[0017] The braking mechanism 2 is connected to the tensioning rocker arm 4 via the first link 3. The tensioning rocker arm 4 has a tensioning wheel 5 at its end. The tensioning wheel 5 is linked to the driving pulley 6 and the driven pulley 8 via a V-belt 7. The tensioning rocker arm 4 has a second link 9 at its end. The top end of the second link 9 has a guide mechanism 10. The guide mechanism 10 has a gear shift lever 12. The gear shift lever 12 is connected to the HST gear shift rocker arm 13 of the hydraulic continuously variable transmission 15 via the third link 11 and the fourth link 14.

[0018] like Figure 2 As shown, the tensioning rocker arm 4 includes a rocker arm rod 41 and a rocker arm bend 42. The tensioning wheel 5 is disposed on the rocker arm bend 42, and the second connecting rod 9 is rotatably connected to the rocker arm bend 42.

[0019] In addition, the second link 9 is fixedly connected to the guide mechanism 10.

[0020] In addition, the first link 3, the second link 9, the third link 11 and the fourth link 14 are all adjustable length rods.

[0021] like Figures 3 to 5 As shown, the first connecting rod 3 is connected to the rocker arm 41 via the connecting buckle 16 and the connecting block 17.

[0022] The connecting buckle 16 includes a connecting spring 161, the head of which is provided with a sliding section 162. The connecting spring 161 is provided with a through rectangular sliding limiting slot 163. The connecting block 17 includes a block-shaped body 171. The end face of the body 171 is provided with a connecting through hole 173. The rocker arm 41 passes through the connecting through hole 173. The side wall of the body 171 is provided with a connecting protrusion 172, which cooperates with the sliding limiting slot 163.

[0023] It should be noted that the connecting block 17 is a rubber component.

[0024] The working principle of the brake linkage mechanism of this high-speed rice transplanter in hilly areas will be explained below.

[0025] When the user presses the brake pedal 1, the brake mechanism 2 activates, acting as a brake. Simultaneously, the brake mechanism 2 drives the first link 3, causing the tension rocker arm 4 to rotate around its axis. This causes the tension wheel 5 to rotate downwards, disengaging and disconnecting power. At the same time, the second link 9 drives the guide mechanism 10 to rotate. The guide mechanism 10, through the third link 11, returns the gear lever 12 to neutral. The guide mechanism 10, through the fourth link 14 and the HST gear rocker arm 13, returns the hydraulic continuously variable transmission 15 to neutral.

[0026] It should be noted that since the first connecting rod 3 is connected to the rocker arm 41 through the connecting buckle 16 and the connecting block 17, and the connecting block 17 itself is a rubber part, the jamming situation is avoided, and part of the load can be unloaded to prevent the connecting rod from deforming.

[0027] The brake linkage mechanism of this high-speed rice transplanter for hilly terrain forces the transmission system back to neutral while simultaneously disconnecting power. When the brake is applied, the tensioner disengages, the engine is unloaded, and this solves the problem of starting difficulties for low-power engines. At the same time, applying the brake disconnects power transmission and forces the transmission system back to neutral, improving driving safety, reducing wear on friction plates, and increasing service life.

[0028] The high-speed rice transplanter for hilly terrain features a compact braking linkage mechanism. By operating the brake pedal, the power can be simultaneously disconnected, the gear shift lever can be returned to neutral, and the hydraulic continuously variable transmission can be returned to neutral. This greatly facilitates the user's operation, avoids safety hazards, and improves the ease of use and safety of the rice transplanter.

[0029] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application.
