Further, the traveling system comprises four wheels, wherein the wheels are connected with a shaft seat through an axle, and the shaft seat is connected with the first frame through an axle; the axle seat is connected with the axle through an air suspension, and the axle is connected with the first frame through a second shock absorber; the wheels are divided into two front wheels and two rear wheels, a driving device is arranged on the rear wheels, and a steering mechanism is arranged on the front wheels.
Further, the first shock absorber and the second shock absorber are spring shock absorbers or rubber shock absorbers.
Further, a bearing bracket is arranged between adjacent axles.
Further, a boom mechanism on the sprayer body may be welded to the rear end of the second frame.
Compared with the prior art, the utility model has the following beneficial effects:
(1) According to the utility model, the two layers of frames are connected through the first shock absorber, the sprayer main body such as the cab, the medicine tank, the spray rod mechanism and the like are arranged on the second frame, and the swing of the wheels is transferred to the spray rod mechanism on the second frame through the action of the first shock absorber, so that the swing received by the spray rod mechanism from the wheels can be greatly reduced due to the action of the second shock absorber.
(2) The utility model also provides a second shock absorber between the first frame and the wheels, and the axle seat is connected with the axle through the air suspension, so that the swing from the wheels can be further reduced.
(3) The cab frame and the medicine box frame are arranged on the second frame and are sunken, so that the gravity centers of the cab and the medicine box can be lowered, and the overall stability of the sprayer is improved; in addition, the visual angle of the cab is reduced, and the running condition of the sprayer is observed during operation.

Detailed Description
The utility model will be further illustrated by the following description and examples, which include but are not limited to the following examples.
As shown in fig. 1, the utility model provides a self-propelled sprayer with a stable chassis, which comprises a sprayer body and a chassis for mounting the sprayer body, wherein the chassis comprises a frame-shaped first frame 1, and a traveling system for advancing or backing is mounted below the first frame 1. The traveling system comprises four wheels 6, each wheel 6 is provided with an axle 7, each wheel 6 is connected with an axle seat 8 through an axle 7, each axle seat 8 is connected with a vertical axle 9 through an air suspension 10, each axle 9 is fixedly connected below the first frame 1, steering mechanisms are arranged on two front wheels of the wheels 6 and drive devices for driving the sprayer to advance are arranged on two rear wheels, and the steering mechanisms and the drive devices are uniformly controlled by a control system on the sprayer body. Four first shock absorbers 2 are uniformly arranged on the first frame 1, a second frame 3 is fixedly arranged on the first shock absorber 2, a sinking cab bracket 4 and a medicine box frame 5 are arranged on the second bracket 3, and a spray rod mechanism on the sprayer main body can be welded at the rear end of the second frame 3. In this embodiment, by providing the first frame 1 and the second frame 3, and providing the first shock absorber 2 between the first frame 1 and the second frame 3, the swing of the wheel 6 is transferred to the first frame 1 first, and then transferred to the second frame 3 under the action of the first shock absorber 2, and at this time, the swing received by the second frame 3 will be greatly reduced, so the swing received by the sprayer main body mounted on the second frame 3 will also be greatly reduced.
In this embodiment, in order to further reduce the swing from the wheel 6, the second shock absorber 11 is disposed between the axle 9 and the first frame 1, so that the swing from the wheel 6 can be further reduced. Preferably, in the present embodiment, the first damper 2 and the second damper 11 are spring dampers or rubber dampers.
In the embodiment, the cab bracket 4 and the medicine box frame 5 are both arranged on the second frame 3 and do not contact with the first frame 1, and the cab bracket 4 and the medicine box frame 5 are sunken, so that the overall gravity center of the sprayer can be effectively reduced, and the stability of the chassis is improved; in addition, the cab bracket 4 is sunken, so that the visual field of a driver can be ensured to be in a lowered position, and the situation of the sprayer during operation can be better observed. Since the chassis of the boom sprayer is relatively high in order to meet the operation requirements of relatively high crops, the axle 9 is generally relatively long, so that the bearing bracket 12 is further arranged between the adjacent axles 9 in order to ensure the stability of the axles 9.
According to the utility model, the damping device, the sinking cab bracket 4 and the medicine box frame 5 are arranged, so that the gravity center of the boom sprayer is effectively lowered, the boom swing caused by wheel swing is effectively slowed down, and the stable operation of the boom sprayer can be ensured.
The above embodiment is only one of the preferred embodiments of the present utility model, and should not be used to limit the scope of the present utility model, but all the insubstantial modifications or color changes made in the main design concept and spirit of the present utility model are still consistent with the present utility model, and all the technical problems to be solved are included in the scope of the present utility model.
