Description

[Detailed Description of the Invention] A clipper blade is installed on the front edge of the bottom plate of the frame, and a blow pipe having a large number of branched blow-off pipes is horizontally suspended diagonally above the clipper blade to constitute a plucking body. There is a portable type that is equipped with an engine integrated with the fan casing, and a handle on the engine side and a hem handle that protrudes so that two people can lift it and operate it, and a type that allows the picking body to be rotated up and down and forward and backward as a traveling body. There is also a traveling type that is attached to a moving body, and has a fan and a chimney mounted directly on a traveling body or directly on a harvesting body, and is operated while accompanying the traveling body.

However, no matter which type is used, the structure of the picking body is almost the same, and in particular, the intervals and number of blowoff pipes branching from the blow pipe are the same as those of the main tea period from Ischa period to Sancha period. It was designed to target tea confections with a relatively short length and a high specific gravity.

For this reason, when picking tea leaves from the tea period to the third tea period, it is possible to pick them one after another without difficulty, but if you are trying to get autumn bancha or milk leaves that are left to grow without picking during the third tea period, When picking tea leaves that have been covered with sheets, etc., the branches and leaves grow long, so the tea leaves bridge between the blow-off pipes, making it impossible to cut them.

If the branches and leaves are short, they will be cut and stored one by one without hitting the ventilation pipe, but if the branches and leaves are long, the upper ends of the branches will hit the bottom of the ventilation pipe and fall forward, while the plucking machine will move forward regardless. This is because the fallen branches and leaves are folded over the next branches and leaves to be picked one after another, resulting in a situation where a large amount of branches and leaves are pushed in between the blow-off pipes at once.

Then, it would be better to install blower pipes horizontally with a longer pitch between the blower pipes from the beginning, but since that would reduce the blowout area, it would be better to install them from the Issa stage where the branches and leaves are short and have a large specific gravity. When picking tea leaves with relatively short branches and leaves from the -tea stage to the third tea stage, it is recommended to use a blower pipe with a short pinch between each blower pipe and a large number of branching pipes. When picking tea leaves with long branches such as autumn bancha, the pitch between each blow-off tube is long and by replacing the small number of blow-off tubes with branched blowing tubes, you can pick any kind of tea leaves. However, a clipper-type plucking machine that provides a method for smoothly and reliably plucking without creating a bridge between the blow-off pipes will be explained using a two-person portable type shown in the drawing.

1 is an engine side side plate 2, a skirting side plate 3, a bottom plate 4 and 2
Machine frame with open front and rear ends made of genuine Azusa pipe 5.

Reference numeral 6 denotes a fan supported on the side of the engine-side side plate 2, in which an impeller (as shown) pivotally connected to the output shaft of the engine 7 is housed.

7 is an engine that is directly attached to the casing of the fan 6, and an impeller and a small diameter pulley (as shown) are pivotally connected to its output shaft.

8 is a clipper blade pivoted to the front edge of the bottom plate 4 so as to be able to move left and right; 9
is a transmission device consisting of the small diameter pulley and the like for driving the clipper blade.

10-11 is an engine side handle and a hem handle attached to the upper frame pipe 5.

Reference numeral 12 denotes a bent pipe that penetrates the engine side plate 2, communicates the proximal end with the crest of the fan 6, and communicates with the blower pipe at the tip, which will be described later. Reference numeral 13 denotes a fastening band for fixing the blower pipe. Reference numeral 14 indicates a bent pipe. This is a positioning projection protruding from the upper surface of the lower side of the tube 12 and the fastening band 13.

Reference numeral 15 denotes a blower pipe which is a branch of the blower pipe 16, and each blower pipe 16.
A blow pipe 15a having a short pitch P between 16 and branching from a large number of blow-off pipes and a blow pipe 15b having a long pitch P and branching from a small number of blow-off pipes are prepared, one of which is selected, and the fastening band It is installed and used in 13.

At this time, the positioning hole 17 is engaged with the positioning protrusion 14, and by drilling several positioning holes 17, the air blowing angle can be adjusted.

Therefore, the plucking method of the present invention using this two-person portable type is carried out as follows.

That is, two workers located on the left and right sides of the brown furrow hold the engine side handle 10 and the hem handle 11, respectively, align the arc shape of the bottom plate 4 of the machine frame 1 with the half side of the brown furrow, and use the clippers. As the blade 8 is moved forward while aligning it with the boundary between the new bud and the stem part, the tea leaves are cut by the clipper blade 8, and are blown backward by the wind blowing from the blow-off pipe 16 near the clipper blade 8. It is housed in a storage bag (as shown) that is attached to cover the rear surface of the frame l.

When the plucking of one half of the brown furrow is completed, the worker switches places, and returns to the starting point while plucking the other half.
- The ridge plucking work is completed.

At this time, since the branches and leaves of the tea confectionery from the -tea period to the third tea period are relatively short, the tip of the tea confectionery does not come into contact with the lower side of the blower pipe 15 before being cut by the clipper blade 8.

Therefore, the tea leaves pass through between the blow-off pipes 16, are cut one after another without falling forward, and are stored in the air one after another, so that the picking operation proceeds without any trouble.

However, this is not the case when picking tea leaves with long branches such as autumn bancha and kabusecha.

In that case, the blow pipe 15a is replaced with a blow pipe 15b having a long pitch P between the blow pipes and a small number of branch pipes.

Therefore, if you perform the same operation using a plucking machine that has been replaced with the blow pipe 15b, the tips of the branches and leaves will come into contact with the lower side of the blow pipe 15b and fall forward, and as the machine advances, even the branches and leaves in front of you will fold over. Even when the pipes become larger, the pitch P between each outlet pipe is long, so the clipper blades 8 cut the two outlet pipes one after another without bridging, and the wind blowing out from the outlet pipes 16 blows the wind backwards. and stored in a storage bag.

In this case, the number of blowoff pipes 16 is small and the blowout area is reduced, so the airflow capacity seems to be reduced. Since the area that receives the wind from the pipe 16 is increased, the wind can be accommodated without any problems in practice.

With this, even tea leaves with long branches can be picked smoothly, but if you still want to pick tea leaves that want to bridge, it is better to replace it with the blower pipe 15c, which will be explained next.

The blower pipes 15c are arranged so that the blower pipes 16 are not branched from the same line, but are branched from the zigzag line 18, so that the effective pinch P' is made longer even though the apparent pitch P is the same.

If the blow-off pipe 16 is replaced with the branched blow-pipe 15c and plucking is performed with this effective pinch P', the actual pinch that affects the bridge can be lengthened without reducing the blow-out area. By using the air pipe 15b, even tea cakes that still want to be bridged can be picked smoothly.

In addition, in the picking method of the present invention, when picking short tea leaves of the above-mentioned portable type for two people, the pitch between each blowing pipe is short and a blowing pipe with a large number of branching blowing pipes is attached and picked. When picking tea confections with long branches and leaves, such as autumn bancha, the pinch between each blow-off tube is long, so we decided to replace a small number of blow-off tubes with branched blow tubes and pick them, so no matter what kind of tea leaves it is, Also, it is possible to smoothly and reliably harvest without creating a bridge between the blow-off tubes.
