Description

Branches-pruning device on back

Technical Field

The utility model relates to a horticulture specialized tool technical field, it is a branch ware is do not gone up to back of body.

Background

The branch on the back is also called a dorsal branch, and refers to a branch vertically emerging upwards from the trunk or branch of a fruit tree. The leaves on the back and the upper branches are large and thick, photosynthesis can be better carried out, more organic nutrients are produced, and the synthesis of organic matters in the tree body is increased, so that the flower buds are more full and plump, and the fruit size is increased.

The reasonable utilization of the branches on the back is beneficial to promoting the reasonable conversion of vegetative growth and reproductive growth, and has very important effect on producing large high-quality fruits.

In order to reasonably utilize the back branches, the back branches and the upper branches also need to be drawn and the shapes of branches need to be adjusted, and especially the back branches and the upper branches are bent, so that the top end advantage is relieved. The branch-pruning device in the prior art is usually fixed with one end and one end of the branch, the action position of the branch-pruning device is only limited to the connecting position of the branch and the trunk, the bending of the middle part or the end part of the branch can not be realized, and the branch-pulling and opening angle of the back upper branch is not very practical. For the back branches, the bending of the back branches can be realized by utilizing a branch-separating device, the branches or the trunks adjacent to the back branches are not depended on, and the bending part is arranged at will, so that the important significance is realized.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a branch ware is do not bough on back of the body that simple structure, easy operation, production efficiency are high.

The technical scheme of the utility model is that:

the branch pruning device comprises a main body arm, the main body arm comprises a first arm and a second arm which form an obtuse angle with each other, clamping jaws are arranged at two ends of the first arm and the second arm respectively, a supporting arm is arranged at the joint of the first arm and the second arm, and the supporting arm is perpendicular to the plane where the main body arm is located.

The back upper branches are strip-shaped linear branches, the clamping jaws of the branch sorting device respectively clamp two points of the back upper branches, and the supporting arms are utilized to arch the branches between the two points, so that the back upper branches can be bent without depending on other branches, and the bending of any position of the back upper branches is realized.

The supporting arm comprises a cross arm, one end of the cross arm is connected with the joint of the first arm and the second arm, and a bulge is arranged at the other end of the cross arm.

The raised arrangement prevents the arched branch portion from sliding off the end of the support arm remote from the body arm under the influence of external forces.

And connecting discs are respectively arranged at the ends, far away from the clamping jaw, of the first arm and the second arm, and tooth blocks perpendicular to the plane where the main body arm is located are arranged on the connecting discs.

The tooth piece is along circumferencial direction evenly distributed on the connection pad, and the tooth piece on the first arm cooperatees with the clearance between the tooth piece on the second arm, and the tooth piece on the second arm cooperatees with the clearance between the tooth piece on the first arm, inserts the tooth piece in the clearance of difference, and the angle between adjustable first arm and the second arm to the lopping demand of adaptation different angles.

The number of the tooth blocks can be selected from 5 to 50 according to the angle adjustment precision, through holes matched with the bolts are formed in the middle of the connecting disc, and the first arm and the second arm are clamped and fixed through the bolts and the nuts after the angles of the first arm and the second arm are determined.

The clamping jaw is a U-shaped arm, and the clamping jaw and the supporting arm are located on the same side of the plane where the main body arm is located.

The branches are only bent in the same plane under the action of the branch-setting device, so that the operation of installing the branch-setting device is facilitated, and the obstruction of the branch-setting device to the branch growth is reduced.

The cross arm is arc-shaped on the section parallel to the plane of the main body arm.

The opening direction of the arc-shaped cross arm faces the opening direction of the clamping jaw, the branches are supported by the back of the cross arm, and the contact surface of the cross arm and the branches is a smooth cambered surface and does not damage the branches. And under the same material consumption, the arc-shaped cross arm is more stable and is not easy to break.

And a fillet is arranged between the inner side wall of the clamping jaw and the side wall of the clamping jaw.

The clamping jaw of U-shaped includes the inside wall in the U line and links to each other and the vertically lateral wall with the inside wall, the inside wall and the branch direct contact of clamping jaw, and the fillet design reduces the damage of other branch ware to the branch.

The utility model has the advantages and positive effects that: due to the adoption of the technical scheme, the back branches and the upper branches are bent, the bending position is not limited, and the damage to the branches is small.
