The spraying device 2 is arranged at the front end of the frame assembly 1. The power unit consists of an engine 3, a main power transmission box 4 and an intermediate gearbox 5. The engine 3 and the main power transmission box 4 are arranged above the front of the frame assembly 1. The intermediate gearbox 5 is arranged below the middle of the frame assembly 1. The power output shaft of the engine 3 is connected to the power input shaft of the main power transmission box 4. The power output of the main power transmission box 4 is connected to the power input shaft of the main power transmission box 4. The shaft is connected to the power input shaft of the intermediate gearbox 5, and the walking mechanism includes a front axle assembly 6, a rear axle assembly 7 and walking wheels. The intermediate gearbox 5 is connected to the power input end of the front axle assembly 6 through a front universal joint shaft 8, and the intermediate gearbox 5 is connected to the power input end of the rear axle assembly 7 through a rear universal joint shaft 9. The above structure is basically the same as the structure of the conventional high-ground clearance sprayer in the prior art. In order to realize the installation and power transmission of rear-mounted agricultural machinery, the present application makes structural improvements to the conventional high-ground clearance sprayer in the prior art.

[0018] See also Figure 1The rear end of the frame assembly 1 is mounted with a rear suspension lifting platform 11 via a rear suspension lifting device 10. A rear end of the rear suspension lifting platform 11 is provided with a suspension mounting point 13 for mounting a rear-mounted agricultural implement 12. A rear suspension gearbox 14 is also mounted on the rear suspension lifting platform 11. The intermediate gearbox 5 is further provided with a rear suspension output shaft 15. The rear suspension output shaft 15 is transmission-connected to the power input shaft of the rear suspension gearbox 14 via a rear suspension universal drive shaft 16. The rear suspension gearbox 14 is further provided with a rear suspension output shaft 15 for power connection to the rear-mounted agricultural implement 12. The suspension mounting point 13 is used for mounting the rear-mounted agricultural implement 12. The rear suspension gearbox 14 is used to draw power from the intermediate gearbox 5 and connect to the power output shaft of the rear-mounted agricultural implement 12 via the rear suspension output shaft 15, transmitting the power to the rear-mounted agricultural implement 12, thereby enabling powered operation of the rear-mounted agricultural implement 12. The rear suspension universal joint drive shaft 16 is used to adjust the lifting and lowering of the rear suspension gearbox 14 to ensure stable power transmission. It is not only rotatable but also retractable. This is a prior art and will not be described in detail here. The rear suspension lifting device 10 can adjust the depth of the rear-mounted agricultural implement 12 to meet the needs of different users and different regions.

[0019] The working principle of this embodiment is:

[0020] Before use, the rear-mounted agricultural implement 12 is installed through the suspension mounting point 13, and the power input shaft of the rear-mounted agricultural implement 12 is connected to the rear suspension output shaft 15, and then the lowering height of the rear-mounted agricultural implement 12 is adjusted by the rear suspension lifting device 10;

[0021] When in use, the power of the engine 3 is transmitted to the front axle assembly 6 and the rear axle assembly 7 through the main power transmission box 4, the intermediate gearbox 5, the front universal joint drive shaft 8, and the rear universal joint drive shaft 9 in sequence. At the same time, the power of the intermediate gearbox 5 can also be transmitted to the rear suspension gearbox 14 through the rear suspension output shaft 15 and the rear suspension universal joint drive shaft 16, and then transmitted to the rear-mounted agricultural machinery 12 through the rear suspension output shaft 15 to realize the operation of the agricultural machinery.

[0022] The rear-mounted agricultural implement 12 can be selected from commonly used agricultural implements in the prior art, such as a rotary tillage device, a furrowing device, a pressing device, etc., which belong to the prior art and will not be described in detail here.

[0023] The rear suspension lifting device 10 includes an outer lifting frame 10a, an inner lifting frame 10b, and a lifting cylinder 10c. The outer lifting frame 10a is fixed to the rear end of the frame assembly 1, and the inner lifting frame 10b slides vertically along the outer lifting frame 10a. The rear suspension lifting platform 11 is fixedly connected to the inner lifting frame 10b. One end of the lifting cylinder 10c is connected to the outer lifting frame 10a, and the other end of the lifting cylinder 10c is connected to the inner lifting frame 10b. When the lifting cylinder 10c is extended or retracted, the inner lifting frame 10b can slide and rise vertically along the outer lifting frame 10a, driving the rear suspension lifting platform 11, the rear suspension gearbox 14, and the rear-mounted agricultural implement 12 mounted thereon to rise and fall, adjusting the distance between the rear suspension lifting platform 11 and the ground.

[0024] The suspension mounting point 13 includes an upper suspension mounting point 13a and two lower suspension mounting points 13b. The two lower suspension mounting points 13b are located on both sides below the upper suspension mounting point 13a and are adapted to the three-point suspension on the rear-mounted agricultural machinery 12. The three-point suspension method is used for installation to ensure the stability of the connection and at the same time have versatility, ensuring that the rear-mounted agricultural machinery 12 in the existing technology can be adapted and installed.

[0025] The rear suspension output shaft 15 is spline-connected to the power input shaft of the rear-mounted agricultural implement 12 or connected via a universal joint. Power transmission can be achieved by inserting the spline into the spline groove, or by using a universal joint as needed, ensuring that power from the rear suspension gearbox 14 is transmitted to the rear-mounted agricultural implement 12 via the rear suspension output shaft 15.

[0026] The rear suspension gearbox 14 is fixed to the rear suspension lifting platform 11. It is equipped with multiple gear pairs, allowing for two or three gears as needed. A clutch lever and a shift lever are located outside the rear suspension gearbox 14. The clutch lever controls the clutch to disconnect power, disengaging the clutch in the non-operating state and engaging it in the operating state. The transmission lever is used to control gear shifting. The internal structure of the gearbox is well known in the industry and will not be described in detail here.

[0027] Example 2:

[0028] The structure of this embodiment is basically the same as that of the first embodiment, and the main difference is the structure of the rear suspension lifting device 10. Figure 2The rear suspension lifting device 10 includes a fixed rod 10d, a lifting rod 10e, an upper connecting rod 10f, a lower connecting rod 10g and a lifting cylinder 10c. The fixed rod 10d is fixed to the rear end of the frame assembly 1, and the rear suspension lifting platform 11 is fixedly connected to the lifting rod 10e. The two ends of the upper connecting rod 10f and the lower connecting rod 10g are respectively hinged to the fixed rod 10d and the lifting rod 10e. The fixed rod 10d, the lifting rod 10e, the upper connecting rod 10f and the lower connecting rod 10g constitute a parallel four-bar structure. One end of the lifting cylinder 10c is connected to the fixed rod 10d, and the other end of the lifting cylinder 10c is connected to the upper connecting rod 10f. When the lifting cylinder 10c is extended or retracted, the parallelepiped structure deforms to cause the lifting rod 10e to rise and fall, thereby driving the rear suspension lifting platform 11 and the rear suspension gearbox 14 and rear-mounted agricultural implement 12 mounted thereon to rise and fall, thereby adjusting the distance between them and the ground.
