[0001]

INDUSTRIAL APPLICABILITY The present invention is such that a single rail is laid between each row of tea tree ridges planted in a row, and the laying rails between the left and right ridges that sandwich the tea tree ridge run as a pair of tracks. The present invention relates to an orbital tea leaf plucking machine capable of performing various operations such as plucking, pruning, and controlling tea leaves over the entire surface of a tea tree ridge.

[0002]

2. Description of the Related Art An orbital type tea leaf plucking machine as described above is conventionally known, and is disclosed in, for example, JP-A-1-174430.
The prior art described in Japanese Patent Laid-Open No. 4-91716 and the like is known, and the applicant has also proposed the prior art described in Japanese Patent Laid-Open No. 4-320613.

This type of device uses a rail laid between the left and right ridges that sandwich the tea tree ridge as a pair of tracks, and has a gate-shaped structure that straddles the tea tree ridge between left and right track carriages that move along the rails. A frame is erected, and a plucking device equipped with a mowing section and a tea leaf storing section over the entire surface of the tea tree ridge is vertically movably attached to the portal frame. Then, when plucking the tea leaves, the track carriage is advanced with the cutting blade lowered to the plucking depth of the tea tree ridge, and the tea leaves are plucked by this forward movement and the plucked tea leaves are stored in a bag. When the process proceeds and the plucking work on the predetermined route is completed, the cutting and tea leaf storage parts are raised to a predetermined height, the tea leaf plucking machine is returned to the work start end at high speed, and the stored tea leaf bags are replaced. , I am going to move to the next plucking work.

[0004]

By the way, when performing the plucking work using the above-mentioned orbit type tea leaf plucking machine, the bag for storing the tea leaves cannot be lowered into the ridge at the middle position of the plucking route. As described above, when the plucking operation of the predetermined route is completed, the tea leaf storage section and the mowing section are lifted to a predetermined height, and the high-speed return to the start end of the plucking operation is performed to replace the stored tea leaf bag and the next plucking step is performed. It is a work method to move to work.

At this time, the weight of the tea leaves stored in the tea leaf bag causes the bottom plate of the tea leaf storage portion and the bag placing table to bend downward, causing a problem of contacting the plucking surface of the tea tree ridges during back running and damaging the tea trees. . This problem can be solved by raising the tea leaf storage unit and the bag placing table to a high level when the vehicle travels back, but when raising it to a high level, the bag for storing the tea leaves, which is a heavy item, becomes high and when returning at a high speed. The problem arises that the driving stability of the vehicle deteriorates.

During the plucking operation, a large amount of tea leaves is plucked with respect to the traveling distance due to the fact that the tea tree ridges are cut over the entire surface, and long tea ridges are used to facilitate the transportation of the bags by adjusting the amount of tea leaves to be stored in the bag. When plucking, it may return again in the middle of the process, and the number of times the bag is changed increases.At this time, the conventional orbital tea leaf plucking machine can be used to remove and replace the tea leaf bag set in the tea leaf storage section. There is also a problem that it is troublesome and work efficiency is poor.

The present invention addresses the above-mentioned problems, and the weight of the tea leaves stored in the bag allows the tea storage part and the bag mounting table to be lifted even if the tea storage part and the bag mounting table are not raised to a high level when traveling backward. It is an object of the present invention to provide an orbital type tea leaf plucking machine in which the bottom plate of (1) does not come into contact with the plucking surface of the tea tree ridges and damages the tea plant, and the tea leaf bag can be easily detached and replaced.

[0008]

In order to achieve the above object, the present invention provides a conventionally proposed orbital type tea leaf plucking machine, in which the mowing part of the plucking device has a plucking upper surface over the entire surface of the tea tree ridge. It has a hair clipper blade that bends with an arc curvature that is almost the same as, an engine and a blower fan, and a wind guide duct that is connected to the blower fan, and pressure is applied from a wind guide duct that is placed horizontally above the hair clipper blade. The wind is blown to the rear of the hair clipper blade and the tea leaves cut by the hair clipper blade are divided and stored in the right half portion and the left half tea leaf storage portion arranged at the rear position of the cutting portion. , The left half of the tea leaf storage bottom plate and the bag placing table that is connected to the bottom plate and extends rearward, the required height rearward and diagonally upward so that the rear part is higher than the machine frame bottom surface of the mowing part. The feature is that it is inclined to It is an.

Further, according to the present invention, the above-mentioned right-half and left-half tea leaf accommodating portions are constituted by a right-half and left-half bag receiving portions which are open at the front and rear and which are connected to the tea leaf bags at the rear openings. In each bag receiving part,
Hooking means for detachably locking the bag receiving part to the rear part of the machine frame of the mowing part, and hooking means for detachably mounting the opening part of the tea leaf bag on both sides of the rear opening are provided on the front part thereof. This is one of the other characteristics.

[0010]

According to the above construction, when returning from the plucking operation stop position on the predetermined path to the work start end at high speed, the weight of the tea leaves stored in the bag causes the bottom plates of the tea leaf storage section and the bag placing table to bend downward. However, since the bottom plate will not come into contact with the upper surface of the plucking of tea tree ridges, damage to the tea tree can be prevented, and when traveling backwards, it is not necessary to raise the tea leaf storage part and the bag placing table to a high position, so that it is possible to load heavy objects. (Bag of tea leaves)
As a result, the driving stability that is derived from the higher driving speed can be improved.

In addition, in the structure in which the hooking means is provided at the front part of the bag receiving part which constitutes the tea leaf storage part in the right half part and the left half part, and the hooking means is provided on both sides of the rear opening, the tea bag is preliminarily set. With the left and right bag holders attached, the left and right bag holders can be fixed to the upper rear frame of the mowing section in a set state, so that the bag holder can be attached to and removed from the mowing section with a single touch, improving work efficiency. Can be achieved.
