Abstract

The utility model relates to a fruit tree pruner. A pruning rod is fixed with a pruner, and a pruner handle is provided with a pulley wheel, wherein, the pruning rod is inserted into a pruning handle rod and fixed by screws, and a handle is arranged on the pruning handle rod; the pruner is connected with the handle by a steel wire. The handle is grasped or loosened to drive the pruner to expand or close. The length of the pruning rod can be adjusted according to the height requirements of fruit trees, and the operation of the pruner is carried out by holding the handle; moreover, the pruner can also be hidden between two protection plates. The utility model has the characteristics of wide adaptive aspects, convenient operation, and convenient carrying.

Description

Fruit trees pruner

The utility model provides and is applied to instrument---the Fruit trees pruner that agriculture fruit tree beta pruning is used.

Before the utility model proposes, carry out the fruit tree beta pruning and use fruittree shear usually.The structure of fruittree shear is similar substantially with cutting to daily life, and promptly by fixedly forming with cutting axle in the middle of upper and lower two scissors, different is to cut two return spring is installed between the handle.This cutting is suitable for the position that human arm can reach and carries out the fruit tree beta pruning, and when carrying out beta pruning for the out of reach position of human arm, just need climb the tree or take ladder carries out, very inconvenient.

The purpose of this utility model is that a kind of Fruit trees pruner that can carry out the usefulness of fruit tree branches of tall trees pruning is provided.

Realize that scheme of the present utility model is, fruittree shear is installed in one cuts bar upper end, handle is installed in the lower end of cutting bar, cut between handle and the handle and be connected by steel wire.When the people holds fixed handle, by the pulling of steel wire, drive and to cut that handle opens or closed, realize the beta pruning action.

The Fruit trees pruner that adopts as above scheme to make, it is scalable to cut bar, hold and be positioned at the handle of cutting the bar lower end, can drive the beta pruning action of cutting bar upper end fruittree shear, thereby, can realize the pruning of fruit tree branches of tall trees, thereby, need not climb the tree or take ladder, reduced pruning person's labour intensity, reduced danger, and used and the collection convenience.

Elaborate below in conjunction with accompanying drawing

Fig. 1 is the utility model structure chart

Among Fig. 1, (1) is hollow structure for cutting the handle bar, pipe or square tube, be provided with finger-hole (1a) in the bottom of cutting handle bar (1), be fixed with handle pulley (1b) in the lower end of cutting handle bar (1) by handle pulley spindle (1c), handle pulley (1b) can rotate by thorny handle pulley spindle (1c).Be provided with on the other hand arbor (2a) on the handle bar being positioned at cutting between finger-hole (1a) and the handle pulley (1b), be provided with steel wire pin (2b) in the lower end of Handle axis (2a), the upper end of handle (2) is hadle (2c).Cutting bar (12) is fixed on by telescopic locking screw (12a) and cuts in the handle bar (1), when unclamping the telescopic locking screw, cutting bar (12) can upper and lower slip in cutting handle bar (1), in order to the pole length of cutting of adjusting averruncator, to adapt to the usefulness of differing heights pruning fruit tree.Be fixed with a pair of scissors backplate (3) in upper end one side of cutting bar (12), be provided with the resetting shaft (3a) and the fixing pin (3b) of fixed blade thereon, fixed blade (4) is installed on the scissors backplate (3) by resetting shaft (3a) and fixing pin (3b), centre position on fixed blade (4), just cut burst position and movable scissors (5) is installed, spring (6) is installed between two shear shanks by cutting axle (7).The handle end of cutting at movable scissors (5) is established a movable scissors fixed screw (8), and the movable scissors end is connected on the pulley support plate (9), is provided with pulley spindle (9a) on pulley support plate (9).Centre at two pulley support plates (9) is equipped with pulley (10) by pulley spindle (9a), is provided with several fixation with steel wire holes (10a) in the outer periphery of pulley (10).Fixed screw (8) can be by the position of fixation with steel wire hole (10a) fixed block (10).Steel wire one end is installed in the fixation with steel wire hole (10a) that is located on the pulley (10), and the other end is by cutting bar (12) and cutting handle bar (1) and handle pulley (1b) is fixed on the steel wire bail (2b) of handle (2).The handle (2c) of holding with a firm grip just can drive steel wire (11) and pull down movable pulley (10), simultaneously, drives movable scissors (5) and fixed blade (4) closure, realizes the beta pruning operation.During release handle (2c), be subjected to the effect of spring (6), two scissors open automatically, to realize beta pruning next time.

Scissors of the present utility model, as temporary transient time spent not, just the fixing pin (3b) that is located on the scissors backplate (3) can be extracted, two scissors and pulley promptly can resetting shaft (3a) for axle is concealed between two backplates, be easy to carry and preserve.

The embodiment explanation

Make Fruit trees pruner by the utility model scheme, make following several parts earlier, assemble then.

A, cut the bar part, on a square tube or garden pipe, weld two scissors backplates (3), press the position boring of resetting shaft (3a) and fixing pin (3b) thereon, fixed blade is cut on the handle holed, connect and be fixed between the backplate by resetting shaft (3a) and fixing pin (3b).By cutting axle (7) movable scissors (5) is installed on the fixed blade (4), cuts two and install spring (6) between the handle.The handle of cutting of movable scissors (5) is fixed on the pulley support plate (9), by pulley support plate (9) pulley (10) is installed in the two pulley support plates, and pulley (10) outer rim is beaten some fixations with steel wire hole (10a).Fixed screw (8) can be adjusted the position of pulley and the tightness of steel wire with the relative installation of steel wire fixing hole (10a).

B. cut handle bar part, get an internal diameter greater than the square tube of the external diameter of cutting bar or garden pipe as cutting handle bar (1), a finger-hole (1a) is installed in its underpart, handle pulley (1b) is fixed on by handle pulley spindle (1c) in its lower end and cuts in the handle bar (1).By Handle axis (2a) handle (2) is installed in again and cuts handle bar (1) bottom.

C. will cut bar (12) insertion and cut in the handle bar (1), and lock and fix with telescopic locking screw (12a).Steel wire (11) one ends are fixed in the fixation with steel wire hole (10a) on the pulley (10), and the other end passes to be cut bar (12) and cuts in the handle bar (1), hangs on the handle pulley (1b), uses steel wire bail (2b) to be fixed on the handle (2) again.

By the Fruit trees pruner that the utility model is made, its scissors is adjustable with the distance of cutting the handle bar, to adapt to the fruit tree beta pruning of differing heights.Scissors is last, and handle is descending easy operating.And scissors can be collected in the scissors backplate, and is easy to carry.

Fruit trees pruner of the present utility model can adapt to the pruning of each planting fruit-trees and other tree.
