Technical Field

[0001] The utility model belongs to the technical field of grass grabbers, in particular to a hydraulic grass grabber. Background Art

[0002] A grass grabber is an excavator with a bucket replaced with a gripper and supporting oil circuits. It can be used to grab grass. It has the advantages of fast operating speed, high efficiency, good maneuverability and easy operation. It is also a kind of agricultural machinery, mainly used for harvesting or cleaning grass. It sucks grass piles, dead leaves, and small branches on the lawn into the trash can through suction, which plays a good cleaning role. The gripper is an important part of the grass grabber. The quality of the gripper design directly affects the working efficiency of the grass grabber.

[0003] For example, the Chinese patent with publication number CN202500173U discloses a new grass grabber that can effectively solve the problems of material falling, limited loading capacity and inconvenient operation during the operation of the existing grass grabber. The technical solution is that the new type includes a bucket and a bracket, the rear part of the bucket is equipped with a bracket, the upper end of the bracket is equipped with a rotating grabbing tooth via a rotating shaft, the bracket is equipped with a hydraulic cylinder, and the upper end of the hydraulic cylinder is connected to the rear end of the grabbing tooth.

The user needs to operate it multiple times to grab the wood, which is time-consuming and laborious, increases the user's working time, and reduces work efficiency. In addition, the wood grabber in the document is not made of good material. Long-term use will cause the wood grabber to wear out, reduce the service life of the wood grabber, and increase the production cost of the wood grabber. In view of this, we propose a hydraulic grass grabber. Utility Model Content
