It is hinged；The hinge joint of 4th oil cylinder 26 and the first arm 23, the hinge joint of the first arm 23 and the second arm 24 and the 4th oil
Cylinder 26 and the line of the hinge joint of the second arm 24 are triangular in shape.The flexible of 4th oil cylinder 26 can drive the second arm 24 opposite
First arm 23 rotates, and realizes that grab bucket 3 moves up and down.
Upper cover 311 is hinged on second arm 24, the 5th oil cylinder 27 is also associated between the second arm 24 and upper cover 311,
5th oil cylinder 27 and the second arm 24 and upper cover 311 are hinged.The hinge joint of second arm 24 and the 5th oil cylinder 27, the 5th
The line of the hinge joint of 311 and second arm 24 of hinge joint and upper cover of oil cylinder 27 and upper cover 311 is triangular in shape.5th oil cylinder
27 stretch can be such that grab bucket 3 is rotated relative to the second arm 24, realize opposite 1 swings of bull-dozer body of grab bucket 3.
Bull-dozer in present embodiment can realize following functions：
First, roadblock is cleared up：Grab bucket 3 is controlled to move up and down respectively using the 4th oil cylinder 26 and the 5th oil cylinder 27, swing,
Can be easily in heaps by the sundries heap such as road surface branch, grab bucket 3 is recycled to be captured, swing span is controlled by the second oil cylinder 22
21 swing, and make grab bucket 3 that sundries is moved to both sides of the road.
2nd, trees are consigned：As shown in figure 3, grabbing folder wood by two bucket tooths 32, wood is pinned by other two bucket tooth 32
Head is fixed, and prevents wood from swinging up and down；Simultaneously during trees are shipped, when placement angle and the lorry of trees park angle
When spending different, bucket tooth 32 can be rotated relative to driving mechanism 2, and bucket tooth 32 drives trees to rotate, and angle is parked without adjust lorry
Degree, improves work efficiency, alleviates labor intensity, easy to operate, a people can complete the shipment of trees, save people
Work.
3rd, hook grabs tree root：As shown in figure 4, its excess-three bucket tooth 32 is opened, a bucket tooth 32 by the 5th oil cylinder 27 control
System can be deep into ground, and tree root is captured, can matching somebody with somebody by four bucket tooths 32 to the smaller trees of some diameters
Conjunction directly uproops trees, eliminates the process that perching knife is added to push over trees with a chainsaw, operating efficiency higher.
Note that it above are only presently preferred embodiments of the present invention.It will be appreciated by those skilled in the art that the invention is not restricted to here
Specific embodiment, can carry out for a person skilled in the art it is various it is apparent variation, readjust and substitute without
