In the tedding operation, the second support wheel 306 contacts the ground and the blade 305 is mounted slightly above the ground. Wherein the blade 305 is arranged to kick the material off in front of the second support wheel 306 to prevent the second support wheel 306 from crushing the material. As shown in FIG. 11, blade 305 has a forward angled configuration that pulls the material apart to reduce drag when walking forward, and second support wheel 306 is disposed behind or within the angled configuration.

In the embodiment of this application, set up expanding spring 303 for shovel board 305 and second supporting wheel 306 can move according to ground undulation condition about elasticity, compression or extension spring have the shock attenuation effect, and expanding spring 303 is making shovel board 305 can go up and down according to ground undulation condition in addition, when reaching imitative ground's purpose, still can guarantee that shovel board 305 has certain pressure to ground and makes shovel board 305 not lifted by the material of tedding.

After the tedding is completed, the connecting bolt 304 can be detached so that the movable frame 302 is separated from the fixed frame 301, and then the separated part of the structure can be placed on the vehicle body. The shovel mounting frame can also be integrally detached from the vehicle body.

In one embodiment, the tedding vehicle is an unmanned vehicle. As shown in fig. 14, the unmanned vehicle further includes a housing frame 400 provided on the vehicle body 200 and a positioning navigation assembly 500. The receiving frame 400 may receive tools and the like, and the positioning and navigation assembly 500 is used for positioning and navigating the unmanned vehicle during operation to ensure traveling along a predetermined traveling path.

The unmanned vehicle is also provided with an RTK positioning module, a power module, a voice module, an image module, a light module and the like, and guarantees automatic operation. This section is not the focus of the present application and will not be described in detail.

The specific process of tedding the rice using the unmanned vehicle is described below.

The method comprises the steps of firstly obtaining position information, area size, shape and other information of an operation land, specifically obtaining a high-definition map in a set area range in a form of unmanned aerial vehicle surveying and mapping, or obtaining dense position coordinate information of the set area by handheld mobile surveying and mapping, obtaining the high-definition map, and then obtaining information of the operation land by terminal equipment (such as a mobile phone and a computer) according to the high-definition map, and making an operation path of the unmanned aerial vehicle.

The operator manoeuvres the unmanned vehicle to the work area, controls the tedder device 100 in the cell phone APP or remote control to descend to the ground, and controls the chains 21 in the two chain drive assemblies 2 to run towards each other (i.e. both towards the direction of the middle of the wheel) or away from each other (i.e. away from the direction of the middle of the wheel).

And clicking a starting operation button, and enabling the unmanned vehicle to travel according to an operation path. Wherein, in the walking process, the shovel board 305 of unmanned vehicle front end dials corn to wheel both sides, and the wheel can not roll corn, and the stirring part 25 on the chain drive assembly 2 of car rear end realizes the stirring to corn along with the in-process that the chain removed to reach the purpose of tedding. The unmanned vehicle can independently operate according to an operation path, meanwhile, an RTK module carried on the vehicle body can compare with a planned path according to an actual operation path, when deviation exceeds a set range, the speed difference of left and right driving wheels is maintained, the effect that the traveling tracks of all the vehicles are parallel is achieved, an image module uploads an operation process to an APP, an operator only needs to monitor whether abnormality exists indoors and temporarily handle the operation process outdoors when the abnormality exists, and labor intensity is reduced.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modifications, equivalents and the like that are within the spirit and principle of the present application should be included in the scope of the present application.
