Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garden machinery, and particularly relates to a novel wood shear clamp based on an excavator. Background Art
[0002] At present, in the process of garden pruning and wood processing, high-speed cutting tools such as chain saws or circular saws are generally used to prune thick branches and tree trunks. When these tools are used in places with sand and gravel, the sand and gravel will damage the cutting edges of the chain saw or circular saw in high-speed motion, making them blunt or even ineffective.
[0003] At the present stage, there is no special equipment for the rough decomposition of tree roots and tree stumps in the wood processing process. The rough decomposition of tree roots is very important for their crushing. If the tree roots are too large, the wood crushing and processing equipment is prone to material jamming or premature damage of tools, bearings, etc. Felling the entire tree root will carry a lot of soil, stones, etc. These soil and stones entering the wood processing equipment will accelerate the wear of the tools. It is necessary to shear and decompose the tree roots and other woods into small pieces, and at the same time remove the soil and stones carried by the tree roots, and better protect the wood crushing equipment. However, the current high-speed cutting tools such as chain saws or circular saws do not have the above functions.
[0004] Based on this, the present utility model provides a novel wood shear clamp based on an excavator to solve the problems occurring in the above working conditions. Content of the Utility Model
[0005] In order to solve the problems existing in the prior art, the present utility model provides a novel wood shear clamp based on an excavator. To achieve the above purpose, the present utility model adopts the following technical solutions:
[0006] A novel wood shear clamp based on an excavator includes a bracket and a pull head connected to the forearm of the excavator. A slewing bearing is arranged inside the bracket, and a slewing bearing dust-proof ring is arranged outside the slewing bearing; the pull head is arranged at the upper end of the bracket, a central swivel joint is arranged inside the pull head, and a slewing motor is arranged on one side of the central swivel joint inside the pull head; a shear blade is arranged at the lower end of the bracket.
[0007] Preferably, a first gear is arranged at the output end of the slewing motor, a second gear is arranged outside the slewing bearing, and the first gear meshes with the second gear.
[0008] Preferably, a central swivel joint mounting plate for fixation is arranged at the upper end of the central swivel joint.
[0009] Preferably, a first connection hole, a second connection hole, and a third connection hole are provided on the bracket. The first connection hole is provided at a position on the bracket close to the horse head, the third connection hole is provided at a position on the bracket far from the horse head, and the second connection hole is provided between the first connection hole and the third connection hole. A first pin shaft penetrates through the first connection hole and is connected to one end of the shear blade oil cylinder, and a second pin shaft penetrates through the second connection hole and is connected to the other end of the shear blade oil cylinder and one end of the shear blade.
[0010] Preferably, a third pin shaft penetrating through the third connection hole is connected to the other end of the shear blade.
[0011] Preferably, the first pin shaft is fixed by a first pressing plate, the second pin shaft is fixed by a second pressing plate, and the third pin shaft is fixed by a third pressing plate.
[0012] Preferably, a fixing plate is provided at one end of the shear blade and at the lower end of the bracket.
[0013] In summary, since the present utility model adopts the above technical solutions, the present utility model has the following technical effects:
[0014] 1. By installing the tree shear on the forearm of the excavator, the present utility model can adapt to different occasions for trimming and wood processing. Moreover, a swing bearing dust-proof ring is provided in the horse head of the tree shear to prevent dust or dirt from entering the meshing area of the swing motor and the swing bearing, reducing the wear risk in the operating area, so as to adapt to cutting in sandy and gravelly occasions.
[0015] 2. The new tree shear frame of the present utility model is of the shearing type and does not require high-speed moving parts. Using this new tree shear can avoid the problem of damage to the cutting edges of chain saws or circular saws during high-speed movement. The tree shear of the present utility model solves the problems of easy jamming of materials or premature damage of tools, bearings, etc. in wood crushing and processing equipment, and also solves the problems that the whole tree root will carry a lot of soil and stones, and these soil and stones entering the wood processing equipment will accelerate the wear of the tools. After the tree roots and other woods are sheared and decomposed into small pieces by the present utility model, the soil and stones carried by the tree roots can be removed, and at the same time, the wood crushing equipment can be better protected.
[0016] 3. The product of the present utility model is of the shearing type, can work under sandy and gravelly working conditions, can effectively process tree roots and wooden stakes, cooperate with wood processing equipment, and through cooperation with the hydraulic system of the excavator, and the cooperation between the swing bearing and the shear blade oil cylinder can enable the shear blade to perform shearing operations at different angles and positions, improving the speed and efficiency of shearing wood, reducing the operation time, improving the work efficiency, and reducing the risk of injury to the operator during the shearing process.
