Among them, the angle adjusting component 23 can adopt an existing angle adjusting mechanism.

[0023] Furthermore, please refer to Figures 1 to 4 , in the adaptive pitching device proposed in this embodiment, the angle sensor 21 includes a horizontal inclination switch 211. The platform assembly 10 includes a platform 11, and the platform 11 is arranged above the walking chassis 30. The horizontal inclination switch 211 is arranged on the platform 11. The angle adjusting component 23 includes a rotating member and an angle adjusting member. The rotating member is rotatably connected between the first end of the walking chassis 30 and the first end of the platform assembly 10, and the angle adjusting member is connected between the first end of the walking chassis 30 and the second end of the platform assembly 10. Specifically, the rotating member includes a first connecting plate 231, a first rotating shaft 232 and a second connecting plate 233. One end of the first connecting plate 231 is fixedly connected to the first end of the walking chassis 30, and the other end of the first connecting plate 231 is rotatably connected to the second connecting plate 233 through the first rotating shaft 232.

In this embodiment, the first connecting plate 231 and the second connecting plate 233 are connected by hinge. Specifically, the angle adjusting member includes a pitching electric cylinder 234, a third connecting plate 235 and a second rotating shaft 236.

One end of the platform assembly 10 is connected to the walking chassis 30 by a hinge connection method, and the other end is connected by the pitching electric cylinder 234; the pitching electric cylinder 234, the horizontal inclination switch 211 and the control system cooperate with each other to enable the platform assembly 10 to be in a horizontal state at all times.

[0024] As Figures 1 to 4 shown, the working principle of the adaptive pitching device provided in this embodiment is as follows:

[0025] This embodiment consists of three parts: a platform assembly 10, a horizontal tilt switch 211 and a walking chassis 30. The platform assembly 10 is arranged above the walking chassis 30, and the horizontal tilt switch 211 is arranged on the platform assembly 10. Figure 2 As shown, a limit block 237 is provided at the upper left of the walking chassis 30, and a first connecting plate 231 is provided at the upper right of the walking chassis 30; the second connecting plate 233 is connected to the first connecting plate 231 through the first rotating shaft 232 on the right side of the platform component 10, so that the platform component 10 rotates around the first connecting plate 231, and a third connecting plate 235 is provided on the lower left side of the platform component 10, and the third connecting plate 235 is hinged to one end of the pitch electric cylinder 234 through the second rotating shaft 236, and the other end of the pitch electric cylinder 234 is hinged to the walking chassis 30. Through this connection method, the platform component 10 and the walking chassis 30 are connected. When the pitch electric cylinder 234 is extended, it can drive the left side of the platform component 10 to rotate around the right side of the walking chassis 30, so that the platform 11 forms a certain angle with the horizontal plane. The angle between the platform 11 and the horizontal plane can be changed according to the change in the stroke size of the pitch electric cylinder 234; since the platform assembly 10 is provided with a horizontal tilt switch 211, the control system can know the angle between the platform 11 and the horizontal plane in real time. Since the stroke size of the pitch electric cylinder 234 is one-to-one corresponding to the angle between the platform 11 and the horizontal plane, when the controller in the control system knows the value of the horizontal tilt switch 211, it will automatically control the pitch electric cylinder 234 to extend or retract the corresponding stroke, thereby keeping the platform 11 in a horizontal state. The adaptive pitch device provided in this embodiment uses an electric cylinder to control the pitch angle of the platform. The electric cylinder control is more accurate and stable, and can more accurately control the angle of the platform.

[0026] Compared with the prior art, the adaptive pitch device provided in this embodiment adopts a platform component, a horizontal tilt adjustment mechanism and a walking chassis. The horizontal tilt adjustment mechanism and the platform component are respectively arranged above the walking chassis. The horizontal tilt adjustment mechanism includes an angle sensor, a control system and an angle adjustment component. The control system is connected to the angle sensor and the angle adjustment component respectively. The angle sensor is used to detect the angle information between the platform and the horizontal plane; the control system is used to control the angle adjustment component to adjust the angle according to the angle information between the platform and the horizontal plane detected by the angle sensor, so as to keep the platform in a horizontal state. The adaptive pitch device provided in this embodiment enables the working platform to always keep a horizontal state when the vehicle is driving on a rugged field, providing a stable working environment for the operators, with a high degree of intelligence, greatly improving the working efficiency of the operators.
