で、走行させつつ茶摘作業ができる茶摘装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention makes it possible for an agricultural power traveling machine equipped with an engine tea picking machine not to fall over during tea picking to run in an extremely stable state. The present invention relates to a tea picking device capable of performing tea picking work.
従来より、茶摘を自動的に行う装置としては、エンジン

りして、極めて人体に有害となっていた。BACKGROUND ART Conventionally, as a device for automatically performing tea plucking, there is a tea plucking machine with an engine. This is generally a tea picking operation in which two workers support the total weight while pulling a storage bag that contains a large amount of tea leaves after tea picking, and moreover, it must be moved according to the unevenness of the upper surface of the tea plant. It had to be done with a lot of nerve, and it was hard work. In addition, the tea plucking machine,
There is a high-speed cutting blade for tea picking, which causes frequent accidents due to fatigue due to heavy labor, etc.
In addition, the sound and vibration of the engine may be transmitted from a position extremely close to or directly to the worker and may be called an occupational disease such as neuralgia, or the engine exhaust gas may be emitted near the worker's mouth. Due to this configuration, there is a high risk that the worker may inhale this, causing gas poisoning, which is extremely harmful to the human body.
このため、このようなエンジン付茶摘機を、農業用動力

高騰し、一般農家では使用できない不都合があった。For this reason, although such a tea picking machine with an engine is attached to a power traveling machine for agriculture, etc., it does not move according to the unevenness of the upper surface of the tea tree, but simply moves along the running ground, There is a serious drawback that tea picking cannot be done well, or the stability of the power train for agriculture is poor, and there is a problem that it can easily fall down and the worker is easily injured. If it is done with a traveling machine, the price will rise so much that it cannot be used by ordinary farmers.

つ茶摘作業ができ、前記課題を解決したものである。Therefore, as a result of earnest and repeated studies to solve the above-mentioned problems, the inventor has found that the invention can be achieved by placing the weight of the agricultural power traveling machine at a position slightly front or rear of both drive wheels of the agricultural power traveling machine. A heavier stabilizing wheel is heavier than that, and an extendable column is installed upright so as to be close to the stabilizing heavy wheel, and an engine is attached to the lateral position of the agricultural power traveling machine through the extendable column. A tea picking device that suspends a tea picking machine, or at a position slightly ahead of both drive wheels of an agricultural power running machine, a supporting heavy wheel that is heavier than the weight of the agricultural power running machine is pivotally supported. A telescopic column is erected in the vicinity of the stabilizing heavy wheel, and from the upper end of the telescopic column,
The tea picking machine with an engine is hung through a tea picking machine support rod that is oriented in a direction substantially orthogonal to the traveling direction, and the telescopic support is a tea picking device that can be moved up and down by hydraulic drive, thereby When the plucking is performed, the power traveling machine for agriculture equipped with the tea plucking machine with an engine is hard to fall down, and the tea plucking operation can be performed while traveling in an extremely stable state, thereby solving the above problems.

る大きな利点がある。These effects will be described in detail. Agricultural power traveling machine A
The center of gravity of the agricultural power traveling machine A is substantially stable due to the existence of the stabilizing heavy wheel 3 which is provided slightly in front of or behind the two driving wheels 2 and 2 and is heavier than the weight of the agricultural power traveling machine A. When the weight wheel 3 is located and the groove between the adjacent tea trees in the tea garden is soft ground, the weight of the stabilizing weight wheel 3 causes it to sink into the soil, resulting in an extremely large reaction force. As a result, the engine-powered tea plucking machine 17 suspended in the horizontal position of the agricultural power traveling machine A is balanced, and tea leaves increase during the work.
Even if the tea picking machine with engine 17 is cantilevered and supported by the agricultural power traveling machine A, there is a great advantage that it can be supported in a balanced and stable manner.
特に、隣接する茶樹間の溝部は狭く、約１０数cm前後で
あり、この中を端部の茶樹を左右に掻き分けながら進む
ので、農業用動力走行機Ａの両駆動輪２，２間の幅も、
せいぜい約３０cm前後しかなく、このように少ない幅で
も、安定用重輪３を設けたことで、エンジン付茶摘機１
７及び刈り取った茶葉が片持ち荷重として作用しても、
バランスを良好に取ることができる。In particular, the groove between adjacent tea trees is narrow, about 10 cm or more, and the tea tree at the end is pushed through to the left and right while advancing, so the width between the drive wheels 2 and 2 of the agricultural power traveling machine A is increased. Also,
It is only about 30 cm at the most, and even with such a small width, by providing the stabilizing heavy wheel 3, the tea plucking machine with engine 1
Even if 7 and the cut tea leaves act as a cantilever load,
Good balance can be achieved.

A heavy weight wheel 3 for stabilization, which is heavier than the weight of the agricultural power traveling machine A, is pivotally supported at a position slightly in front of the two drive wheels 2, 2 of the vehicle, and a telescopic column B is set up close to the heavy weight wheel 3 for stabilization. Install the expansion support B
From the upper end of the tea picking machine 17 with an engine, the tea picking machine 17 is hung via a tea picking machine support rod 12 that is oriented in a direction substantially orthogonal to the traveling direction, and the telescopic brace B is hydraulically driven so that it can be lifted and lowered. As a result, in addition to the effect of claim 1, first, a small turn of the agricultural power traveling machine A can be performed, and secondly, the engine-operated tea plucking machine 17 can be easily moved up and down.

Since the heavy weight stabilizing wheel 3 is rotatably supported at a position slightly forward of, the direction can be changed with the minimum turning radius r 1 as shown in FIG. it can. More specifically, assuming that the stabilizing heavy wheel 3 is provided at a position quite front (see the chain double-dashed line portion in FIG. 8), the positions of the driving wheels 2 and 2 and the stabilizing heavy wheel 3 are separated from each other. However, the turning radius r 2 for reversing becomes large, the small turning is not effective, and there is a drawback that it cannot be used in a narrow place, but in the present invention, such a thing can be surely avoided.
