Description

Fruit tree swiftly draws a device

Technical Field

The patent of the utility model relates to a fruit tree integer technical field especially relates to fruit tree draws branch integer device.

Background

In the growth and breeding of fruit trees such as apples, walnuts, cherries, pears, peaches, Chinese chestnuts, plums, persimmons and the like, in order to increase the light receiving and ventilating areas of branches and leaves and improve the yield, new branches growing every year need to be shaped by branch pulling, branch pressing, pruning and the like. The branch pulling is a common mode for shaping fruit trees, and the traditional branch pulling method is that most parts of a wooden wedge are forcibly wedged into the ground, the part on the ground is tied by a thread rope, and the other end of the wooden wedge is tied on a branch needing to be pulled. The problems of high labor intensity, low working efficiency, high consumption of wood wedges, incapability of recycling and the like exist in the work process. And the tree climbing is needed for branches at high positions, and the climbing is unsafe when the branches are climbed. The development of an efficient and safe branch pulling device is urgently needed.

Disclosure of Invention

The utility model aims at providing a fruit tree branch pulling device, the device have adopted the claw of scissors shape to replace the rope to tie a knot in the aspect of the branch is binded, have avoided because the rope reinitiates the current situation of branch. The claw is matched with a special telescopic supporting rod, the claw can be placed in the middle upper section of the branch through the telescopic rod under the condition of not climbing, and the rope connected with the claw is pulled down to enable the claw to firmly sleeve the branch to play a role in binding the branch. The underground fixing part combines the earth drill principle with the cutter eccentric rotation principle, and can quickly drive the earth into the ground through an electric drill and rotate the blade to cut the earth so as to offset the pulling force caused by branches. Solves a series of problems of unsafe climbing, poor working efficiency, high labor intensity and the like. The cost is moderate and the recycling can be realized.
