Description

[Detailed description of the invention] [Industrial application field] This invention suspends the tea picker from the tip of the swinging rod, significantly reducing the labor burden on the worker, and allowing it to freely adapt to the unevenness of the top surface of the tea plant. This invention relates to a tea plucking device that can adjust its height, etc. to make tea plucking work safer and faster.

[Conventional technology and its problems, etc.]

Recently, various types of tea picking machines that automatically perform tea picking have been developed and are commercially available. In most of these cases, the tea picking machine was carried out by one or two workers. This requires supporting the full weight of the engine-equipped tea plucking machine while dragging the collection bag that holds a large amount of picked tea leaves, and it also has to be moved according to the irregularities on the top surface of the tea plant. The work required a great deal of nerves and was hard labor. In addition, the tea plucking machine is equipped with a high-speed cutting blade for picking tea, and the current situation is that unexpected injuries frequently occur due to fatigue caused by heavy labor. In addition, the sound and vibration of the engine can be transmitted very close to or directly to the worker, causing occupational diseases such as neuralgia, and the exhaust gas from the engine can be emitted near the worker's mouth. Because of its structure, there was a high risk of workers inhaling the gas, causing gas poisoning, which was extremely harmful to the human body.

[Means for solving problems]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor created the present invention by providing a mounting part at the lower end of the support pole, attaching this mounting part to an agricultural power running machine, and attaching it to the upper end of the support support. , the base of a swinging rod is pivotally mounted, the swinging rod is capable of swinging on a vertical plane, fixed at an appropriate angle on the vertical plane, and is formed to be expandable and contractable in its longitudinal direction; The tea-picking machine is elastically suspended from the tip of the swinging rod via multiple coil springs or elastic bodies such as rubber, so that the tea-picking process can be performed while driving the tea-picking machine. This eliminates the need for effort such as lifting the tea picker, making it easier to move and protecting you from injuries.The elastic material expands and contracts, allowing you to efficiently adjust the height according to the irregularities on the top of the tea plant. ,
In addition, the tea leaves can only be picked from leaves that are close to new buds, and the tea leaves can absorb engine vibrations to a large extent, making them harmless to health, thus eliminating the above-mentioned drawbacks.

In Figures 1 and 2, one tea picking machine 23 is shown.
Although it is installed on the post 1 with one swinging rod 3, a device with a similar structure may be used as an agricultural power traveling machine 26 and also as a device for picking tea from tea plants on the left and right sides at the same time. .

[Effect of idea]

In the present invention, a mounting part 2 is provided at the lower end of the pillar 1, this mounting part 2 is attached to the agricultural power traveling machine 26, and the base of the swinging rod 3 is pivotally attached to the upper end of the pillar 1. The rod 3 is capable of swinging on a vertical plane,
In addition, it can be fixed at an appropriate angle on the vertical plane, and is extendable and retractable in the longitudinal direction, and the tea picker 23 is connected from the tip of the swinging rod 3 via an elastic body 22 such as a plurality of coil springs or rubber. By using a tea picking device that hangs elastically, firstly, it reduces the labor burden on the worker, making tea picking work safer and faster, and secondly, it reduces the unevenness on the top surface of tea plants. The height can be easily adjusted according to the height, and thirdly, the height can be easily adjusted according to the size of the tea plant.

To explain these effects in detail, first, when this is used in a tea garden etc., the total weight of the tea picking machine 23 is transferred to the agricultural power traveling machine 2 through the swinging rod 3 support 1.
6, there is no need to manually lift the tea picker 23 as in the past, and the tea picker is freed from heavy labor and is extremely mobile, reducing accidents caused by high-speed mowing blades, etc. This is particularly useful from the standpoint of worker safety, and as the labor burden on workers is significantly reduced, it is possible to improve the efficiency of tea-picking work, and it is relatively easy to use. It also has the effect of making it possible to work continuously for long periods of time.

Further, the tea picking machine 23 has a plurality of elastic bodies 2 such as coil springs or rubber etc. from the tip of the swinging rod 3.
2, the elastic body 22 allows the instantaneous vertical expansion and contraction movement of the elastic body 22 to pick the new buds (tea leaves) on the tea plant, which most of the time have an uneven surface. The tea thinner 23 lightly touches the top of the new bud on the tea plant, floats up, moves down again, touches the next new bud, and is harvested by the tea thinner 23, so only those that are close to new buds are harvested. The tea leaves can be harvested with a uniformity similar to that achieved manually, and although the labor burden is small, the tea can be picked easily and reliably. Therefore, in the past, the tea plucking machine 2 was manually adjusted according to the uneven surface.
The height adjustment was done while supporting the entire weight of the 3. This adjustment required a lot of nerves and was hard work, but these drawbacks can be solved all at once with the present invention.

In particular, since the tea plucking machine 23 is suspended via a plurality of elastic bodies 22, the set position of the tea plucking machine 23 can be kept stable, and thereby new buds (tea leaves)
Although the work of picking chisels requires skill, it has the great advantage that it can only be done by lightly touching the tea picker 23 in a stable state.

Furthermore, the vibrations caused by the engine of the tea picking machine 23 are absorbed to some extent by the elastic body 22, and the vibrations transmitted to the person operating the tea picking machine 23 are reduced, which greatly reduces the risk of neuralgia caused by this vibration. I can.

In addition, even in the conventional two-person tea picking machine 23, if it is a component of the present invention, it is suspended, so
Since it can be operated by one person, and in particular can be operated from a distance from the engine part installed on one side, the engine noise is relatively low, and the risk of inhaling the exhaust gas is also reduced, so that it does not harm human health. .

In addition, the swinging rod 3 can swing on a vertical plane, can be fixed at an appropriate angle on the vertical plane, and can be expanded and contracted in the longitudinal direction. The hanging tea plucking machine 23 can be set at an appropriate position in the vertical and horizontal directions (in the vertical direction in Fig. 2). , it is possible to perform extremely good tea picking work.

In addition, if a rotating plate 21 is provided or its swinging rod 3 is rotatably attached to the support 1, it is possible to set the tea tree at the end of a long tea tree after turning it over, or to change the direction. It's easier to convert,
Alternatively, the position of the tea plucking machine 23 can be adjusted as appropriate during tea plucking work, and the efficiency of the tea plucking work can be further improved.
