Description

Fruit tree spray base angle open-angle device

Technical field

The utility model relates to a kind of fruit culture apparatus, specifically a planting fruit-trees spray base angle open-angle device.

Background technology

In fruit tree management process, the holding appliance that orchard worker generally adopts cord to open a business as fruit tree spray base angle, cord one end is bundled in branch proper site, and the other end is fixed on trunk or ground.This planting fruit-trees spray angle of release mode, if solution ties up cord not in time, often cause binding place of branch cord to produce contriction, it is thick that the lighter suppresses branch to increase, and severe one causes branch injured; If binding position is improper, easily makes open a business not in place or branch of the base angle of fruit tree spray occur arc curved thus cause bow crook stripping serious, therefore cannot reach desirable angle of release effect.In addition, branch is drawn with cord, also by the restriction of degree of lignification, time and effort consuming, and also on fruit tree, stay cord also can affect other production management activities in orchard.

For above problem, some scientific research institutions and enterprise development go out the open-angle device that alternative cord draws branch, existing adjustable open-angle device, angle of release angle is grasped flexibly, but its complex structure, production cost is high, complex operation, is difficult to large-scale promotion application in actual production process.

Utility model content

The purpose of this utility model is just to provide a kind of fruit tree spray base angle open-angle device, to solve the problem of the high and complex operation of existing open-angle device complex structure, production cost.

The utility model is achieved in that

One planting fruit-trees spray base angle open-angle device, other branch bar is connected in the front end of an armed lever of trunk U-shaped cover hook, the angle that described other branch bar and described trunk U-shaped overlap the coupler body plane of hook is 145 °-150 °, be connected to inverted U-shaped other branch hook in the front end of described other branch bar, the angle of the coupler body plane of described other branch bar and described other branch hook is 55 °-60 °; Knuckle front stop lever is connected in the front end of another armed lever of described trunk U-shaped cover hook, described knuckle front stop lever comprises linking arm and blocking arm, the angle that described linking arm and described trunk U-shaped overlap the coupler body plane of hook is 85 °-90 °, and described blocking arm is positioned at the top of the coupler body plane of described trunk U-shaped cover hook.

Described blocking arm is overlap to described trunk U-shaped the knee that at the bottom of the hook of hook, direction is bending.

When carrying out angle of release operation, first trunk U-shaped cover rhampotheca is needed on the position of angle of release at major branch, and be fixed on major branch together with blocking arm, then hook side shoot with inverted U-shaped other branch hook, and to the downward pulling force of Lateral shoot formation, thus make between side shoot and major branch, to form required angle.

The utility model is a kind of easy easy-to-use, time saving and energy saving, working life is long, effective and cost is low fruit tree angle-opening device, it is opened an angle and can regulate as required, be suitable for the apple neonatal tress angle of release of the multiple fruit trees such as apple tree, pear tree, peach, apricot, be particularly useful for giving birth to semi-lignified branch angle of release then, Be very effective.Structure of the present utility model is simple, with low cost, is easy to make, easy to operate, easy to use, and angle of release is flexible, repeatedly repetitive cycling can use, greatly reduce labour intensity and cost of investment.The utility model angle of release is effective, does not damage shoot tissue, is conducive to tree vigo(u)r and is formed, promote into colored, can be applicable to the growing season management of each planting fruit-trees, be specially adapted to newly-built short anvil dense planting apple orchard.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is using state reference diagram of the present utility model.

In figure: 1, trunk U-shaped cover hook, 2, other branch bar, 3, other branch hook, 4, linking arm, 5, blocking arm.

Embodiment

As shown in Figure 1 and Figure 2, the utility model comprises four parts such as trunk U-shaped cover hook 1, other branch bar 2, other branch hook 3 and knuckle front stop lever, and wherein, knuckle front stop lever is connected to form by linking arm 4 and blocking arm 5.

Trunk U-shaped cover hook 1 is U-shaped crozier, is socketed in needs on fruit tree trunk and carries out the position of angle of release to raw shoot then during use.Be connected to other branch bar 2 in the front end of an armed lever of trunk U-shaped cover hook 1, the angle that other branch bar 2 and trunk U-shaped overlap the coupler body plane of hook 1 is 150 °, substantially identical for the angle of angle of release with shoot.Being connected to inverted U-shaped other branch hook 3 in the front end of other branch bar 2, for being stuck in shoot, pinning shoot from the top down, to change the direction of growth of shoot.Other branch bar 2 is 60 ° of angles with the coupler body plane of other branch hook 3, to realize reliable other branch effect.Knuckle front stop lever is provided with in the front end of another armed lever of trunk U-shaped cover hook 1, knuckle front stop lever is connected to form by linking arm 4 and blocking arm 5, the armed lever that one end and the trunk U-shaped of linking arm 4 overlap hook 1 connects, and linking arm 4 is perpendicular to the coupler body plane of trunk U-shaped cover hook 1, another termination blocking arm 5 of linking arm 4, retaining wall 5 is horizontally placed on the top of the coupler body plane of trunk U-shaped cover hook 1, and retaining wall 5 also overlaps direction at the bottom of the hook of hook 1 to trunk U-shaped have certain flexibility, to withstand on the front side of trunk, overlap together with hook 1 with the trunk U-shaped be socketed on rear side of trunk, form stable supporting and positioning mechanism that is relative and other branch hook.

The utility model can adopt the antirust zinc-coated wire of diameter 3mm to bend shaping, have not easily get rusty, intensity is high, once drop into the feature used for many years, greatly can reduce labour cost and the fund input of fruit tree management.
