Description

[Detailed description of the invention] This invention aims to automatically pick tea leaves from tea plants, and instead of cutting and collecting tea leaves with a machine like in the past, the tea stems are collected using a device. The purpose is to automatically collect tea confectionery by pulling it out.

Conventionally, it is known to automatically collect the new shoots of tea confectionery by clamping them with an elastic body such as rubber and lifting them up.

However, this method has the following fatal flaws and has not yet been put into practical use.

That is, when lifting the tea stems of tea confectionery, the reaction force of the lifting force is necessarily applied to the device.

Therefore, the operator must not only withstand the weight of the considerable weight of the device, but also withstand the reaction.

As mentioned above, the device is quite heavy, and as this reaction force is constantly applied, the device is dragged into the tea tree during the operation, and it requires a great deal of effort to withstand this. This is the reason why the device has not yet been put into practical use.

The present invention has been developed in view of these circumstances, and aims to eliminate the drawbacks and put it into practical use mechanically enough to automatically pick tea confectionery.

This will be explained based on what is shown in the drawings.

Since FIG. 3 shows the main parts of this apparatus, the main structure will be explained first based on this figure.

Rotating drums 2, 2 and 2゜2 are respectively mounted on the upper and lower parts of the construction plates 1, 1, which are arranged to correspond to the left and right phases. Kake hands over the sexual belt 3,3.

In addition, flexible clamping members 4 are attached to the lower ends of the construction plates 1, 1.
, 4 are provided correspondingly.

As will be described in detail later, these construction plates 1, 1 are designed to approach or separate from each other, and when they approach each other, the roots of the tea stem a of the tea plant are held tightly by the clamping members 4, 4 on both sides. The buds attached to the tea stalks a are picked up and collected between belts 3 and 3 which are held and moved upward.

In FIGS. 1 and 2, gears 5, 5 are fixed to the drum shafts 2', 2' of the upper rotating drums 2, 2, and the gear 5 meshes with a drive gear 7 fixed to the rotating shaft 6. Furthermore, a rotating plate 33 is pivotally connected between the drum shaft 2' and the rotating shaft 6, and the gear 5 is rotated along the circumferential surface of the driving gear 7. Allows rotation.

Reference numeral 8 denotes a chain, which is driven by a chain gear 9 fixed halfway through one rotating shaft 6 driven by a prime mover 28 (see Fig. 1), which rotates the other chain gear 9'. The rotation drives the other rotating shaft 6 via the intermediate gear 10.11.

A fixed shaft 12 is erected approximately at the center of the construction plate 1-, and a crank arm 14 pivotally mounted to a crank plate 13 is supported on the fixed shaft 12.

A gear 16 is fixed to the shaft 15 of the crank plate 13.13,
This gear 16 is an intermediate gear 1 that transmits rotation of a prime mover 28.
It meshes with 7.

Reference numeral 18 denotes a link arm fixed to the fixed shaft 12, and a support shaft 19 is attached to the other end, and this support shaft 19 is pivotally supported by a machine frame 22, which will be described later.

Reference numeral 21 denotes a brush which is rotated in a sliding manner above the belts 3, 3, and its rotating shaft 20 is pivotally supported by the machine frame 22.

The left and right end plates 24 and 25 of the machine frame 22 are provided with an inlet 26 and an outlet 27 for tea plant buds, respectively, and the above-mentioned loading device shown in FIG. 2 is mounted inside this machine frame 22. Then, the tea stem insertion hole C between the belts 3 and 3 is aligned with the receiving port 26 and the sending port 27.

That is, the tea plant to be picked is introduced into the machine through the receiving port 26, passes through the insertion hole C between the belts 3, and is led out from the sending port 27.

23 is a guide plate for picked tea leaves or buds, 28 is a prime mover, 29 is a gear case, 30.30 is a handle attached to the top of the machine frame 22, 31 is a storage bag, and 32.32 is a branch collection. It is a branch board.

Its effects will be explained.

When the prime mover 28 is driven, its rotation is transmitted to the rotating shaft 6 and also to the chain gear 9
'It is also transmitted to the other rotating shaft 6 via the intermediate gears 10 and 11, and rotates the rotating drums 2, 2 via the drive gear 7 gear 5, so that the belts 3, 3 are moved upward with their inner surfaces facing each other. to drive this.

On the other hand, the rotation of the prime mover 28 passes through an intermediate gear 17 and a gear 16.
Rotate the crank plate 13.13 and its crank arm 14.
14, the construction plates 1, 1 are pushed forward or backward.

As a result, both belts 3, 3 are repeatedly brought closer to each other or separated from each other.

At the same time, the holding members 4, 4 provided at the lower part of the belt 3 are also repeatedly moved toward and away from each other.

In this case, the fixed shaft 12 of the construction plates 1, 1 has its support shaft 19 supported by the machine frame 22 via the link arm 18, and is rotated between the gear shaft 2' of the rotating drum 2 and the rotating shaft 6. Moving plate 33
are pivotally connected, so even when the belts 3 and 3 repeatedly move toward or away from each other, the gear 5 fixed to the drum rotation shaft 2' remains on the surface of the drive gear 7, as described above. During the rotation, the rotation of the rotating shaft 6 is directly transmitted to the rotating drum 2.

Therefore, I applied this machine to the upper layer of the tea plant that should be picked, and applied this to the first layer.
In the figure, when moving from the left to the right, the tea stems a of the tea plant are introduced into the machine from the receiving port 26 of the machine frame 22 and sent out from the delivery port 27, but during this time both belts 3, 3 are brought closer together. The tea stem a is held between the belts 3 and 3, and at the same time, the roots of the tea stems are held and fixed between the holding members 4 and 4, and the tea leaves from the tea stems are picked up between the belts 3 and 3. The buds and stems are harvested.

The leaves picked during this handling are swept backward by a brush 21 above the belts 3, 3 and stored in a storage bag 31.

This invention is a mechanical device that can mechanically facilitate the picking of tea confectionery, which was previously impossible in practical terms, and also allows anyone to harvest tea confectionery without requiring any skill, improving efficiency. can be done.

Moreover, since the tea is harvested by handling the tea stems, only high-quality tea candies can be harvested without contamination with hard stems or old leaves, unlike in conventional cutting methods.

In addition, when handling the tea stems, the base is held between the clamping members, so there is no chance of cutting or damaging the tea plants, and the reaction force caused by the lifting is reduced. Since it does not place any burden on the equipment, the operator can carry out the work while bearing only the weight of the equipment, which allows the work to be done easily and improves efficiency.

Furthermore, since the clamping member and the handling member move toward each other or move away from each other, the tea stalks can be securely clamped or lifted up, and the picking can be easily performed. Because of this, the tea stalks are securely gripped without being dislocated, and the tea stalks can be reliably harvested.

In addition, since the main parts of the device, the clamping member and the lifting member, are repeatedly moved toward or away from each other,
The purpose can be achieved simply by applying the insertion hole of the tea plant to the upper surface of the tea plant and moving it, so that continuous automatic picking of tea confections is possible.
