[0010] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0011] Figure 1 It is a structural schematic diagram of the utility model;

[0012] Among them: 1. working teeth, 2. working shaft, 3. support sleeve, 4. bearing, 5. connecting sleeve, 6. accumulator, 7. protective cover, 8. hydraulic motor, 9. reversing valve, 10. fixing ring, 11. beating rod. DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The embodiments in the basic utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] like Figure 1 As shown, the figure includes a working shaft 2, on which working teeth 1 are sleeved, one end of the working shaft 2 is connected to a support sleeve 3, and the other end of the working shaft 2 is connected to a hydraulic motor 8 through a bearing 4 and a connecting sleeve 5. A reversing valve 9 is fixedly connected to the hydraulic motor 8, and an accumulator 6 is connected to the reversing valve 9. One end of the working shaft 2 is connected to the hydraulic motor 8, the reversing valve 9, and the accumulator 6 to form a driving force, and the working teeth 1 are driven to swing forward and backward through the working shaft 2, slapping the nuts on the tree to make them fall down, thereby realizing the harvesting operation.

[0015] The working tooth 1 includes a fixed ring 10 sleeved on the working shaft 2, and two beating rods 11 connected to the fixed ring 10. The two beating rods 11 are arranged opposite to each other so that the two beating rods 11 are located on a line. The two beating rods 11 on the working tooth 1 realize forward and reverse motion under the drive of the reversing valve 9 and the hydraulic motor 8, thereby beating the nuts on the tree and causing the nuts to fall off; since one circle of the working tooth 1 is composed of one beating rod 11, a tooth structure with gaps is formed, which will not damage the tree.

[0016] The support sleeve 3 includes a sleeve sleeved on the working shaft 2, and also includes a side plate fixed on one side of the sleeve, and the side plate is connected to the shield 7. The hydraulic motor 8 is connected to one end of the working shaft 2 and is located in the sleeve of the support sleeve 3.

[0017] The working teeth 1 are arranged in a staggered manner, so that the working teeth 1 form a tooth-like structure on the working shaft 2. Each working tooth 1 includes a fixing ring 10 and two beating rods 11, and the two beating rods 11 are in a line. After each working tooth 1 is staggered and regularly arranged, the whole is formed into a tooth shape, which is more conducive to beating nuts on the tree and completing the work with high efficiency.

[0018] Working principle: The main engine supplies oil to the reversing valve 9, and the electromagnets on both sides of the reversing valve 9 are frequently and alternately energized to realize the frequent alternating forward and reverse rotation of the hydraulic motor 8, thereby driving the working teeth 1 to swing forward and backward through the working shaft 2, hitting the nuts on the tree to make them fall down, thereby realizing the harvesting operation.

[0019] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
