Felling and holding device

Abstract

The invention discloses a felling and holding device. The device comprises two holding plates which are provided with cutting saws and are arranged in an arc shape, the upper ends of the two holding plates are rotationally connected, the inner sides of the two holding plates are fixedly connected with a holding belt, a plurality of rotating columns are rotationally connected to each clamping beltat equal intervals, the holding belt is filled with liquid, and each rotating column is divided into a plurality of cavities by a holding belt. According to the device, through the interaction of structures such as a cavity, a flow guide hole, a rotary column and the like, the internal liquid flows when the wood pile is extruded, the part which is extruded under the action of pressure can be flattened, the flattened part can be attached to the surface of the timber pile, the friction force is increased, at the same time, under the limit of the rotating column, the whole timber pile is fixed, the wood pile does not rotate under the action of gravity when lifted upwards, so that the wood piles are tightly held, cutting of the cutting saw is facilitated, the safety of the felling is improved,and the wood piles are prevented from loosening and falling.

Description

technical field [0001] The invention relates to the technical field of feller components, in particular to a feller holding device. Background technique [0002] At present, with the continuous increase of labor costs, the felling of large quantities of trees in forest farms, farms and municipalities can no longer rely solely on manpower. Special logging machines have been developed to replace manpower. An important component in a logging machine is the holding device. [0003] The current clamping device is only the cantilever to control the degree of clamping, but because the cross section of the stake is not a smooth circle, there will be a gap between the stake and the cantilever, and it will rotate under the action of gravity when it is hoisted , so that the trunk cannot be tightly occluded, and if the occlusion is not tight, the trunk will be deflected and fallen, which poses a greater safety hazard. Contents of the invention [0004] The purpose of the present inv...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, as: present holding device is only the degree of cantilever control holding tightly, but because the cross-section of wooden stake is not a smooth circle, between wooden stake and cantilever There will be gaps between them, and they will rotate under the action of gravity when hoisting, so that the trunk cannot be tightly occluded. If the occlusion is not tight, the trunk will be deflected and fallen, which poses a great safety hazard
