Description

The present invention relates to a tea leaf plucking device for cutting tea branches and leaves.

When the cut tea branch leaves are stored in the tea leaf storage means by blowing wind power, the tea branch leaves are caught in the partition portion provided in the tea leaf guiding means. When one tea branch leaf is caught, another tea branch leaf is caught on the tea branch leaf, and it accumulates and becomes a lump. Not only does this hinder the smooth transfer of tea branches and leaves, but when the loaf grows close to the cutting means, the loaf pushes down the tea branches and leaves to be cut, making it impossible to cut the tea branches and leaves. Then, the cutting work had to be interrupted in the middle of the tea ridge, and the clogged tea branches and leaves had to be removed.

Therefore, conventionally, as in Patent Document 1, a brush that rotates vertically is provided in front of the partition portion to rotate the brush, or as in Patent Document 2, a pin that is vertically raised is reciprocated in parallel. Then, the tea branch leaves were forcibly distributed to the left and right of the partition and removed so that the tea branch leaves would not be caught.

In the conventional devices of Patent Documents 1 and 2, not only the structure becomes complicated and the manufacturing cost increases, but also when the brush or pin is damaged, there is a risk that parts such as the brush or pin may be mixed into the tea branch leaves. ..

Further, if the device for rotational movement or reciprocating drive fails during cutting, the cutting operation cannot be continued with the failure. In addition, when trying to work with the partition part caught, another worker other than the driver of the tea leaf picking device must accompany and manually remove the tea branch leaves caught in the partition part. did not become. In other words, more man-made work was required than usual. In addition, this removal work was performed near the cutting means, which was dangerous.

An object of the present invention is to provide a tea leaf plucking device capable of preventing tea branch leaves from being caught in a partition portion and reliably distributing tea branch leaves to the left and right.

The first means of the present invention is
Cutting means for cutting tea branches and leaves,
A means of accommodating the cut tea branches and leaves,
A blowing means for transferring the tea branches and leaves cut by the cutting means to the accommodating means by blowing wind, and a blowing means.

The explanation will be given based on the drawings. The tea leaf plucking device is mounted on a passenger-type work machine in which two crawler-type traveling devices 2 are connected by a gate formwork 4 with a tea ridge 20 sandwiched between them, and has a cutting blade 21 under the gate formwork 4. The cutting means 5 is arranged. The cutting blade 21 is a hair clipper type, and has a structure in which two upper and lower cutting blades 21 reciprocate in the ridge width direction to cut tea branches and leaves. The cutting means 5 can move up and down to a predetermined cutting height. A tea leaf guiding means 6 is provided behind the cutting means 5, and a mesh-shaped storage bag 7 is detachably provided behind the tea leaf guiding means 6 for ventilation. Generally, two storage bags 7 are provided on the left and right sides, and each of them is responsible for storing tea branches and leaves cut at approximately half in the width direction of the tea ridge 20. Therefore, the mouths of the respective storage bags 7 are adjacent to each other at the substantially central portion of the tea leaf guiding means 6, and a partition portion 15 for dividing the tea branch leaves into two left and right is provided. The partition portion 15 is formed in a substantially semicircular shape, and the tea leaf accommodating means (accommodating) behind half the length before and after the tea leaf guiding means 6 connecting the cutting means 5 and the tea leaf accommodating means (accommodation bag 7). It is provided on the bag 7) side. In this embodiment, the partition portion 15 is configured to be bent in a substantially semicircular shape, but may be bent into a polygonal shape or an acute angle instead of a substantially semicircular shape. In front of the partition portion 15, a tea leaf guide plate 16 extending upward and left and right from one point 16A of the bottom plate 6A of the tea leaf guiding means 6 toward the partition portion 15 is provided. Since the partition portion 15 is behind half the length before and after the tea leaf guiding means 6 connecting the cutting means 5 and the tea leaf accommodating means (accommodation bag 7), the tea branch leaves are fed when cutting a large amount of tea branches. A sufficient acceleration section (time) due to wind power can be obtained, and a sufficient distribution effect by the tea leaf guide plate 16 can be obtained. Blower fans 9 and 10 are installed on the gate formwork 4, and are connected to a large number of blowout branch pipes 13 by flexible blower ducts 11 and 12, and the tea branch leaf T is blown as a means of blowing. I'm sending. (The means of ventilation is not limited to this)

As an example of the tea leaf guide plate 16, a tea leaf guide plate 16 having a triangular cross-sectional shape will be described as Example 1. The shape formed by the tea leaf guide plate 16 and the bottom plate 6A of the tea leaf guiding means 6 has a shape like a triangular pyramid. It is desirable that the tea leaf guide plate 16 is symmetrical, and if it is symmetrical, the amount of tea branch leaves T stored in the left and right storage bags 7 can be made substantially the same. By integrating the tea leaf guide plate 16 with the partition portion 15, the structure is further simplified, gaps at unnecessary joint portions are eliminated, and the tea leaves can be transferred more smoothly.

The tea ridges 20 made by tailoring tea trees into ridges are planted and cultivated at regular intervals, and the ridges between the tea ridges 20 and the tea ridges 20 are formed into a gate form 4 straddling the tea ridges 20. The traveling device 2 is mounted to travel and perform cutting work. The height of the cutting means 5 is adjusted to the cutting position of the tea ridge 20, the operation unit 19 supplies power to the cutting means 5 and the blowing means, and the traveling device 2 starts the cutting work of the tea branch leaf T while traveling. To do.

The tea branch leaves T extending on the upper surface of the tea ridge 20 are cut by a clipper-shaped cutting blade 21 that covers almost the entire width of the tea ridge 20, and many of the blowing means located on the front upper portion in the traveling direction of the cutting means 5. It is transferred toward the left and right storage bags 7 by the blowing wind blown from the blown branch pipe 13. At this time, the tea branch leaf T cut near the central portion of the cutting blade 21 is started to be transferred in the direction of the storage bag 7 by the wind power, and is along the surface of the tea leaf guide plate 16 provided in the front portion of the partition portion 15. It is distributed to the left and right, and is stored in each of the left and right storage bags 7.

When the left and right storage bags 7 or one of the storage bags 7 is full, the operation unit 19 stops the power of the cutting means 5 and the ventilation means, and replaces the storage bags 7. By repeating this work up to the cutting work end point, the cutting work is completed.

As another example (Example 2) of the tea leaf guide plate 16, a tea leaf guide plate 16 having an arc-shaped cross section is shown in FIG. The movement when the tea branch leaf T hits the tea leaf guide plate 16 is the same as that in the first embodiment.

As another example (Example 3) of the tea leaf guide plate 16, a tea leaf guide plate 16 having a polygonal cross section is shown in FIG. The movement when the tea branch leaf T hits the tea leaf guide plate 16 is the same as that in the first embodiment.

In this embodiment, a riding type working machine is used as an example, but the same applies even if the riding type working machine is not used.

In this embodiment, since the two storage bags 7 are attached to the left and right, the partition portion 15 is one place, but the present invention is not limited to this, and the same applies even if there are a plurality of partition portions 15.
