Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tea tree shredding device, particularly for medium cutting (pruning) performed once every 6 to 8 years on tea plantations (rows) that have reached maturity. This relates to a shredding device used for work.

[Conventional technology]

Traditionally, tea plants that have reached maturity (tea gardens, tea tree rows) are 6 to 8
As the years pass, the tree height increases, making it inconvenient to pick tea confectionery, and the tree's strength also weakens, making it impossible to produce good tea confectionery. Intermediate cutting (pruning) work is being carried out to cut and renew the trees. This medium-cutting (pruning) work involves moving the number of tea tree ridges using a two-person pruner or deep pruner, or a clipper-type cutting blade with traveling devices on both the left and right sides. I am trying to cut off the top of the.

[Problem to be solved by the invention]

By the way, as mentioned above, there is a medium cut (mid cut) in which the upper part of the tea plant is cut without moving the number of tea plant ridges using the cutting blade of the recan method.
During pruning work, if you cut off the height that should be cut at the same time, the volume of branches and leaves that fall below the tea plant is large and cannot be dropped below the tea plant. In the case of tea plants, the amount of tea leaves increases and becomes a hindrance to the passage of subsequent quantities, so this is divided into three or four times and finely cut to fall under the tea plants and on the quantity. This required a lot of time and effort.

The present invention has been made to solve the above problems.

[Means to solve the problem]

In order to achieve the above object, the present invention provides (L) a shredding device that cuts the upper part of the tea plant while moving along the length of the tea plant ridge; A vertical shaft that rotates horizontally is supported on the machine frame, which is equipped with a traveling device that rotates horizontally.Multiple cutting blades are attached to this vertical shaft in the vertical direction to shred the upper part of the tea plant over a predetermined height. (2) The vertical shaft, on which multiple cutting blades are mounted in the vertical direction,
A plurality of cutting blades are supported in the width direction of the tea tree ridge, and (3) the cutting blades, which are provided in multiple stages in the vertical direction on the vertical axis, are horizontally supported on support arms of multiple degrees that protrude from the vertical axis in the radial 1-1 direction. Each is characterized by being pivoted so that it can rotate.

[For production]

With the above configuration, the tea tree shredding device of the present invention can: (1) When performing mid-cutting (pruning) of tea tree furrows without moving the number of tea tree furrows, the tea tree shredding device can simultaneously cut the upper part of the tea tree at the height to be cut in multiple stages; The leaves are shredded and released, and the shredded branches and leaves are dropped below the tea plant or in quantity, and the medium cutting (pruning) work is completed at - degree.

■ The upper part of the tea plant at the height to be reaped is simultaneously shredded in multiple stages in the vertical direction, and multiple vertical axes are provided in the direction of the tea plant ridges, so the cut branches and leaves are finer. It is easy to process.

■ Since the cutting blade is pivoted on multiple arms that protrude radially from the vertical axis, it can adequately cope with the growth of tea plants in the front and back directions, increasing work speed and efficiency.
