Description

Branch puller shell

Technical Field

The utility model relates to a fruit tree branch arrangement and repair type instrument field, in particular to shell of branch puller.

Background

In the production practice of fruit tree planting, in order to better receive the sunlight irradiation of the fruit tree and reduce the mutual shielding among the leaves, the tree shape of the fruit tree is usually required to be adjusted. There are many ways to adjust the tree shape of fruit trees, such as pruning, controlling tree vigor and branch pulling. The branch pulling and angle opening are used as a supplementary measure for pruning, and the branch pulling and angle opening method has the characteristics of small damage to fruit trees, reversible change and the like, and is widely applied to the production practice of fruit tree planting.

traditional branch pulling and angle opening mostly adopts a wooden stick to support, and the mode that the stay wire is pulled wastes time and energy. The pulling wire is pulled in a mode that the pulling wire with fixed length is tied to the branch to be pulled and a fixed point respectively, the fixed point can be a main body or a fixture such as a stone, and therefore the branch to be pulled is pulled towards a specific direction to adjust the angle. Along with the growth of branches, the limitation of the pull wire on the adjustment of the pulling angle of the branches is large, and the fixed pulling angle cannot be further adjusted.

Therefore, the branch pulling device with the length of the pull wire adjustable is designed to have important significance for the branch pulling and angle opening operation of fruit trees. The stay wire is used as a soft wire, and in order to realize the function of adjusting the length of the stay wire, the stay wire is usually wound in a winding disc in the branch pulling device in a winding mode, when the stay wire is used, the stay wire is pulled out by a specific length, and then the winding disc is locked by a locking device, so that the specific stay wire length is obtained.

The stay wire in the branch puller generally adopts a high-horsepower wire, and the wire with the diameter of 0.1-0.5mm can meet the requirement of the branch puller on the tension. The main part of the branch puller comprises a shell which is usually manufactured by injection molding in the form of injection molding parts, the shell needs to be processed in a split mode and then assembled for processing convenience, meanwhile, in view of the stability of the stress of the branch puller, a pull wire is generally led out from the middle of one end of the branch puller shell, and the middle of the shell is a seam between an upper shell and a lower shell. The stay wire is a wire with a thinner diameter and is easy to clamp in a gap between the upper shell and the lower shell, so that the shell with a reasonable structure is arranged, and the stay wire has important significance for leading out the stay wire.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a casing of branch drawing device, simple structure can effectively reduce the clamp, the card influence of casing seam crossing to acting as go-between.

The technical scheme of the utility model is that:

The utility model provides a branch puller shell, includes the casing, is located the wire reel of casing and twines the acting as go-between on the wire reel, the casing includes casing and lower casing, the edge of the one end of casing is equipped with 2 stop line archs down, and 2 lower casings between the stop line arch are equipped with the recess of acting as go-between, it is equipped with the stop line recess with the bellied department of corresponding of stop line to go up the casing, the stop line is protruding to cooperate with the stop line recess.

The casing adopts the mode production and processing of moulding plastics, need set up other structures including the wire reel in the casing, therefore the casing adopts the split type processing of casing from top to bottom, is connected through elastic buckle between the casing. The wire spool is cylindrical, the axis of the wire spool is perpendicular to the upper shell and the lower shell, and the side face of the wire spool is used for winding a stay wire. The height 1/2 of the wire spool corresponds to the plane where the upper and lower housings are joined. The thread stopping groove on the lower shell is an outlet of the pull thread, and the thread stopping bulges facing the upper shell are arranged on two sides of the thread stopping groove, so that the pull thread can be prevented from being clamped into the seam of the upper shell and the lower shell towards two sides. The stop line groove of the upper shell is matched with the stop line protrusion, so that the stop line groove can be sealed into a through hole when the upper shell and the lower shell are closed, the integrity of the shells is ensured, and meanwhile, the limiting effect of the shells on the pull line is further enhanced.

The elastic buckle is arranged at the inner side of the lower shell and close to the line blocking bulge, the elastic buckle comprises a main body part and a clamping cap, the main body part is vertically connected onto the lower shell, the clamping cap is a triangular bulge on the side surface of the main body part, the upper shell is provided with a clamping cap matched clamping groove, and the main body part is provided with a through hole.

Adopt the connected mode of elasticity buckle between the upper and lower casing, have certain elasticity because of injection molding itself, the utility model discloses be provided with 4 elasticity buckles between the well upper and lower casing. At the wire blocking groove, the tightness of the connection of the upper and lower housings is particularly important, and therefore, one of the 4 snaps needs to be disposed near the wire blocking groove. Through set up the through-hole on the elasticity buckle of blocking line recess department, compromise the function of being qualified for the next round of competitions of blocking line recess and the tight type of casing connection about the blocking line recess department.

The wire spool is cylindrical, a wire guide plate is arranged between the wire spool and the wire pulling groove, a wire groove is formed in the wire guide plate, and the distance from the bottom of the wire groove to the lower shell is matched with 1/2 of the height of the wire spool.

The pull wire on the wire spool is wound or pulled out of the wire spool along the circumferential direction, and the wire spool is flat and cylindrical, so that the pull wire cannot be displaced too much in the axial direction of the wire spool, the pull wire is prevented from being separated from the wire spool, and therefore the wire guide plate is arranged on the lower shell, and the position of the pull wire on the axial line of the wire spool is limited by the wire guide groove.

Preferably, the upper shell is also provided with a wire guide plate, the wire guide plate is provided with a wire guide groove, and the wire guide plates of the upper shell and the lower shell are matched with each other to limit the movement path of the pull wire on the axis of the wire spool.

The shell is in a diamond shape, the stay wire groove is located at one end of a long shaft of the diamond shell, and elastic buckles are arranged at two ends of a short shaft of the shell.

The two ends of the long shaft of the shell are in the stress direction of the branch puller, one end of the long shaft is provided with a wire groove, and preferably, the other end of the long shaft is in a hook-shaped structure.

The utility model has the advantages and positive effects that: due to the adoption of the technical scheme, the branch puller is convenient to process, reasonable in structure, not easy to clamp the stay wire, and high in product stability.
