Description

Fruit tree branch pulling device

Technical Field

The utility model relates to a forestry and fruit industry instrument field especially relates to a fruit tree branch puller.

Background

In order to make the fruit tree grow well, the position of the branch on the fruit tree is usually required to be adjusted to adjust the tree body structure, improve the illumination condition, alleviate the tree vigor, promote the flower bud differentiation and fruit in advance.

However, part of branches are too high and are not easy to operate, so climbing operation is often performed by climbing a ladder or stepping on a stool, the working efficiency is low, the workload is increased, even accidents caused by falling injury due to climbing operation occur, and the safety is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fruit tree branch puller has the operation of ascending a height that need not operating personnel, improves operating personnel factor of safety's advantage.

In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a fruit tree branch pulling device, includes couple, extensible member, is used for injecing the mounting of extensible member length and is used for the connecting piece be connected with the fruit tree trunk, the couple sets up the one end at the extensible member, and the other end of extensible member passes through the rope and is connected with the connecting piece.

When the technical scheme is implemented, an operator firstly extends the telescopic piece, hooks the hook on a higher branch, then pulls the branch downwards and shortens the length of the telescopic piece, when the telescopic piece is shortened to a proper length, the operator fixes the length of the current telescopic piece by using the fixing piece, and then fixes the connecting piece on the trunk of the fruit tree; due to the arrangement of the telescopic piece, an operator can operate without climbing, the safety coefficient of the operator is improved, and the operator can adjust the length of the telescopic piece to determine the bending angle of the branch, so that the phenomenon that the branch is broken due to overlarge bending angle is prevented; when the angle of the branch is adjusted, an operator can gradually increase the bending angle of the branch according to a time period, only the length of the telescopic piece needs to be adjusted in the process, the position of the connecting piece on the trunk of the fruit tree does not need to be moved, and the operation of the operator is facilitated; the telescopic piece can move in multiple degrees of freedom due to the arrangement of the rope, so that the hook can hook branches in different directions, and the fruit tree branch puller is convenient to use.

Further, the extensible member includes that interior pole and slip cover establish the outer loop bar in interior pole, the one end of outer loop bar is sealed, and the blind end is connected with the rope, and the one end that interior pole kept away from the loop bar blind end is connected with the couple, be provided with the round flange on the inside wall that the blind end was kept away from to the outer loop bar, the one end that interior pole kept away from the couple is provided with the boss that is used for colliding with the flange mutually.

By implementing the technical scheme, the telescopic part is simple in structure and easy to operate, and one end of the outer loop bar is sealed, so that the phenomenon that the inner bar slides out of the outer loop bar is effectively prevented; the flange and the boss are arranged to effectively prevent the inner rod from being separated from the outer sleeved rod.

Further, the mounting sets up to the dead lever of L type, offers the opening that is used for supplying dead lever and interior pole butt on the overcoat pole, the overcoat pole is located open-ended both sides and is provided with the support, and the corner of dead lever is articulated with the support, the dead lever be used for with the terminal surface of the one end of interior pole butt set up to the cambered surface.

By implementing the technical scheme, the position between the inner rod and the outer sleeve rod is fixed by the friction force and the extrusion force between the fixed rod and the inner rod, the fixing process is simple and convenient, and the operation is easy.

Further, a rubber layer is bonded on the end face of the fixed rod, which is used for being abutted against the inner rod.

By implementing the technical scheme, the arrangement of the rubber layer increases the friction force between the fixed rod and the inner rod, so that the position relation between the inner rod and the outer sleeve rod is not easy to change after the inner rod and the outer sleeve rod are fixed, and meanwhile, the rubber layer has larger deformation capacity, so that the extrusion force applied when the inner rod is fixed by the fixed rod can be reasonably increased when the position of the fixed rod is arranged, and the inner rod is fixed more stably; the rubber layer reduces abrasion between the fixed rod and the inner rod, and the service life of the fruit tree branch puller is effectively prolonged.

Further, the connecting piece sets up to the clamp, it has the protective layer to bond on the clamp is close to the lateral wall of fruit tree.

Implement above-mentioned technical scheme, the phenomenon that the clamp setting destroyed the fruit tree bark on the fruit tree trunk has been reduced in the setting of protective layer and has taken place.

Further, the protective layer is made of cotton cloth.

Implement above-mentioned technical scheme, the cotton has better gas permeability, prevents that the bark of fruit tree trunk from taking place because of the not good phenomenon of rotting of gas permeability.

Compared with the prior art, the utility model has the advantages of:

the arrangement of the telescopic piece enables an operator to operate without climbing, and the safety factor of the operator is improved;

secondly, an operator can adjust the length of the telescopic piece to determine the bending angle of the branch, so that the phenomenon that the branch is broken due to overlarge bending angle is prevented;

thirdly, the telescopic piece can move in multiple degrees of freedom due to the arrangement of the rope, so that the hook can hook branches in different directions, and the fruit tree branch puller is convenient to use.
