Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1 like Figure 1 and Figure 5 As shown in the figure, this specific embodiment provides a weeding vehicle chassis, including a chassis body 1. The top of the chassis body 1 is provided with an upper guide rail 2, and a side guide rail 3 is provided on one side of the chassis body 1. The bottom of the chassis body 1 is provided with a mounting bracket 18 and a mounting bracket 2 19. The mounting bracket 18 is located at the front of the chassis body 1 and its length direction is parallel to the forward direction of the chassis body 1.

Due to the complex terrain, the chassis body 1 will vibrate during movement. To prevent the weeding component or spraying component 40 from moving or even falling off due to vibration, magnetic seats 9 are embedded in the upper guide rail 2 and the side guide rail 3. The adsorption surface of the magnetic seat 9 is set on the inner wall of the sliding groove 10 and is flush with the inner wall of the sliding groove 10. In this specific embodiment, the magnetic seat 9... Multiple magnetic seats 9 are arranged along the length of the upper guide rail 2 or the side guide rail 3, and all of them are located on the same side. The magnetic seats 9 on the two upper guide rails 2 are also arranged on the same side. The magnetic seats 9 are existing technology and will not be described in detail in this article. After the weeding component or spraying component 40 is installed along the slide groove 10, the knob on the magnetic seat 9 is rotated.

When using this weeding component 44, the size of the mounting seat 16 is smaller than that of the mounting seat 16 in other working conditions, and the magnetic seat... 9. The guide strip 34 on the mounting base 16 cannot be opened, so that the two mounting bases 16 can move on the upper guide rail 2 under the action of the drive component. Specifically, the drive component includes a lifting motor 37, which is set on the connecting base 2 45 and located on one side of the side guide rail 3. The motor shaft of the lifting motor 37 is set along the width direction of the chassis body 1.
