Description

Mower Technical Field The application relates to the technical field of mowers, in particular to a mowing machine. Background Grass cutters are becoming increasingly popular with people because they can replace the manual work to cut and trim lawns in predetermined areas. In order to improve steering performance of a mower, a steering wheel is usually arranged in front of the mower, and in order to prevent the steering wheel from colliding with other objects during traveling, an anti-collision plate is usually arranged at the front end of the mower. However, after the anti-collision plate is arranged on the mower in the related art, the length of the vehicle body can be greatly increased, which is not beneficial to the miniaturization development of the mower. Disclosure of utility model The embodiment of the application provides a mower, which is compact in structure and flexible in steering. In order to achieve the above object, the embodiment of the present application provides the following technical solutions: The first aspect of the embodiment of the application provides a mower, which comprises a power device, a mower body, two steering wheels, a baffle plate and a baffle plate, wherein the mower body is connected with the power device, the two steering wheels are arranged at the front part of the mower body and are oppositely arranged at two sides of the mower body at intervals along the width direction of the mower, the baffle plate is arranged at the front end of the mower body, two ends of the baffle plate are positioned in the outer outline of the two steering wheels when seen in the length direction of the mower, the two ends of the baffle plate are respectively provided with an avoidance part in the width direction, the avoidance part is positioned at one end, close to the mower body, of the baffle plate, an avoidance space for the steering wheels to rotate is formed between the avoidance parts and the steering wheels, one plumb surface parallel to the length direction is defined as a first plane, one plumb surface parallel to the width direction is defined as a second plane, the projection of the steering wheels to the ground extends along the length direction when the steering wheels are positioned in the first state, the front projection of the steering wheels to the ground is at least partially overlapped with the front projection of the first plane, and the length of the steering wheels to the ground when the steering wheels are positioned in the second state, and the projection of the length of the steering wheels to the ground is at least 45 degrees is larger than the front projection of the second plane. According to the mower provided by the embodiment of the application, the baffle is arranged at the front end of the mower body and is arranged in the outer contours of the two steering wheels, so that the size of the mower along the width direction can not be increased under the condition of increasing the baffle, the miniaturization development of the mower is facilitated, the risk of collision in a narrow passage or when the mower is close to an obstacle can be reduced, and the operation safety is improved. Through set up the portion of dodging in the baffle one side towards the steering wheel, can provide more spaces for the steering wheel, thereby reduce the interference between steering wheel and the baffle, this helps improving the steering performance and the flexibility of lawn mower, especially under narrow space or the circumstances that needs big angle to turn to, set up the baffle and the automobile body and more compact in the ascending space of fore-and-aft direction, then be favorable to whole car compactness, but baffle and automobile body interfere easily, card earth or card grass easily between baffle and the automobile body, be unfavorable for the passing performance of lawn mower, but set up too loose between baffle and the automobile body, then whole car length is too big, be unfavorable for the steering flexibility of whole car. Therefore, when the steering angle of the steering wheel is larger than 45 degrees, the orthographic projection of the steering wheel and the avoiding part on the second plane is at least partially overlapped, the compactness of the mower in the length direction is ensured, and the grass clamping problem between the steering wheel and the mower main body is prevented. When the steering wheel is in the first state, the steering wheel and the avoiding part are at least partially overlapped when seen from the width direction, so that the avoiding part extends to a position between the two steering wheels towards one end of the vehicle body, that is, a part of structures of the baffle plate can share a part of space in the length direction with the steering wheels, and compared with the situation that the whole baffle plate is directly arranged in the front side space of the steering wheels, the compactness of the mower can be improved. In on
