fig. 1 is a schematic perspective view of the present utility model.
FIG. 2 is a schematic diagram of an embodiment of the present utility model.
In the figure:
1. the device comprises a walking mechanism, 2, a frame, 3, a swing arm, 4, a connecting rod, 5, a platform, 6, a vertical rod, 7, a limiting piece, 71, a sleeve, 72, a connecting piece, 8, a supporting seat, 9, an electric push rod, 10, a connecting arm, 11, a positioning nut, 12 and a through hole.
The specific embodiment is as follows:
For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will now be described in further detail with reference to the accompanying drawings and the following examples, so that the public can better understand the method of practicing the present utility model, and the specific embodiments of the present utility model are as follows:
A mower lifting structure is characterized by comprising a travelling mechanism 1, wherein the travelling mechanism 1 is provided with a frame 2 in a fixed structure mode, the frame 2 is provided with swing arms 3 in a hinged structure mode, two swing arms 3 which are arranged in parallel are in a group, the two groups of swing arms 3 are respectively arranged on the left side and the right side of the frame 2, the frame 2 is provided with a power mechanism for driving the swing arms 3 to rotate around a hinged point with the frame 2, the lower part of the swing arms 3 is provided with a connecting rod 4 in a hinged structure mode, the connecting rod 4 is provided with a platform 5 in a hinged structure mode, the frame 2 is provided with a limiting piece 7 in a fixed structure mode, the limiting piece 7 is connected with a vertical rod 6 in a sliding structure mode, the lower part of the vertical rod 6 is connected with the platform 5 in a fixed structure mode, and the vertical rod 6 can play a guiding role in vertical lifting of the platform 5. Through the design of pole setting 6 and connecting rod 4, guarantee that swing arm 3 can be along vertical lift through connecting rod 4 drive platform 5, reduce front and back space occupation, and then reduce mower automobile body weight to power take off has been reduced, economic nature is improved.
Specifically, the running mechanism 1 is a crawler chassis or a wheeled chassis, in this embodiment, the crawler chassis, so as to meet the action capabilities of various complex terrains, and the mowing device is installed on the platform 5, which is not described in detail in the prior art.
It should be noted that, the power mechanism includes supporting seat 8, electric putter 9 and linking arm 10, and supporting seat 8 sets up in frame 2 up end with fixed knot structure mode, and supporting seat 8 links to each other with electric putter 9 with the hinge structure mode, and electric putter 9 other end links to each other with linking arm 10 with the hinge structure mode, and linking arm 10 links to each other with swing arm 3 with the hinge structure mode, utilizes electric putter 9 to promote linking arm 10 and removes, and then linking arm 10 promotes swing arm 3 around rotating with the hinge point of frame 2 to realize the lift of lower part.
