Description

A Composite Device for High Branch Pruning and Stubble Protection

technical field

The utility model relates to a forestry machine, in particular to a composite device for high-branch pruning and stubble protection, which is suitable for high-altitude operations and can realize tree branch pruning and stubble maintenance.

Background technique

Forestry is one of the important agricultural industries in my country, and tree pruning is an important part of forestry tending projects. Tree pruning has strict requirements. Improper tree stubble retention or unreasonable pruning stubble maintenance will seriously affect tree development and even cause stubble rot and cause tree disease. Pruning of various trees has different requirements on stubble height and stubble quality. For example, if fast-growing poplar leaves longer stubble, water will easily accumulate in the stubble and rot into holes; slow-growing pines and cypresses have poor healing ability. The stubble will inevitably cause the stubble to be too large to heal quickly and cause disease to rot. Therefore, when pruning medium and large branches (generally, the diameter of the wound is more than 2-3cm), it is necessary to spray disinfectant on the pruned stubble for stubble protection.

Through the retrieval of prior art documents, it is found that the patent application number: 201210105504.0, name: DC high-branch saw, which includes a casing, a DC motor, a transmission structure, a sprocket wheel, a chain, and a guide plate.

The working principle and process of a composite device for high branch pruning and stubble protection of the utility model:

1) Work preparation: the operator puts the liquid medicine used to maintain the stubble in the liquid tank; installs the pruning and stubble protection saw on the extension rod or the end of the manipulator through the connecting block of the main shell, and fixes the push rod; looking for work The object is to clamp the branch to be pruned in the toothed tiger mouth of the main housing; the clamping push rod drives the brake wire to overcome the elastic force of the clamping spring to make the clamping claw clamp the branch to be pruned.

2) Pruning and stubble care work simultaneously:

Pruning process: the start of the motor drives the bevel gear at the end of the motor to rotate, the rotation of the bevel gear drives the coaxial gear and then the eccentric wheel, and the rotation of the eccentric wheel drives the connecting rod and then drives the slider to reciprocate in the chute of the guide plate to store medicine The saw blade reciprocates under the drive of the slider; the pruning push rod starts to pull the pruning gate line, and the guide plate rotates around the bearing under the drive of the pruning gate line, and the saw blade exerts pressure on the branches. The branches are cut under the combined action of the pruning spring, and at the same time the pruning spring is stretched.

Stubble Nursing: While pruning, the medicinal liquid in the medicinal solution tank is sprayed out by the fan-shaped nozzle through the drug delivery tube, just spraying on the back of the saw blade, and the reciprocating motion of the saw blade applies the medicinal liquid to the stubble.

3) Reset: After the work is finished, the spring of the guide plate in the stretched state will pull the guide plate back to its original position, and the clamping spring will restore the clamping claw to its original position, and finally realize the reset.
