A blower 47 is provided in
Hose 100A connected to the bellows hose, and a blowing nozzle 100B connected to the end of the bellows hose 100A.
And are provided. Similar to the nozzle 49 in the blowing means 46 shown in FIG. 4, a plurality of blowing nozzles 100B are arranged along the width direction of the ridge picked by the cutting blade 43 of the picking device 4, and the opening thereof has a flat cross section. Is configured. The opening is directed toward the top of the tea ridge where the tea leaves to be plucked by the cutting blade 43 of the plucking device 4 are located.

As described above, the blowing nozzle 100B is a member capable of adjusting the direction of the opening in addition to fixing the opening at the top of the tea tree ridge with the opening being directed. . FIG. 7 is a partial view seen from the front of the plucking machine for explaining the configuration for adjusting the directing direction of the opening. In FIG. 7, the end of the bellows hose 100A connected to the blower 47 is a tea tree ridge. Is connected to the blowing nozzle 100B at a substantially central position in the width direction. The blowing nozzle 100B includes a ring member 100C serving as a rotation support member.

An end of the blowing nozzle 100B opposite to the connection position after the bellows hose 100 is rotatably supported by a support plate 100D attached to the lower surface of the riding plate 24, and the rotation position is maintained. ing. The blower nozzle 100B supported by the support plate 100D is provided with a rotating handle 100E protruding outward from the support plate 100D. By operating the rotating handle 100E, it is possible to change the directional direction of the opening. The support plate 1
00D can be held by a latch mechanism (not shown) provided in 00D.

As a configuration for changing the directivity of the opening described above, although not shown, the above-described rotary handle 100
Instead of E, a sprocket provided coaxially with the blower nozzle 100B is combined with a power transmission element mounted on the sprocket and a driving sprocket mounted on the other of the transmission elements, and the driving sprocket is connected to a driving source such as a motor. And the rotation direction and the amount of rotation of the drive source may be operated by the control unit 25. By adjusting such a directional angle, air can be efficiently blown to the top surface of the tea plant, and by adjusting to the height of the tea plant, a posture for more efficiently removing the dew attached to the tea leaves can be prepared.

On the other hand, as shown in FIG. 7, in addition to providing the blowing nozzle 100B at a plurality of locations in the width direction of the tea ridge, the blowing nozzle 100B is divided into two in the width direction of the tea ridge. It is also possible to adopt a configuration in which the respective areas are collectively used as a blowing range, or a configuration in which a bisected area is divided and used as a blowing range. In this way, by using a single-structured nozzle or a divided nozzle so that the blowing range can be collectively set, unlike the case of using a plurality of nozzles as shown in FIG. Since a continuous air blowing range can be set, it is possible to prevent the occurrence of tea trees in which air does not hit between nozzles as in the case of a plurality of nozzles.

Since the present embodiment has the above configuration,
The traveling device 3 is mounted between the tea ridges, and the tea ridge picking operation is performed. When the plucking operation of the tea leaves is started by the plucking device 4, the work of removing the dew adhering to the tea leaves by the blower blowing means 100 is performed. That is, the blower 47
The air from is blown. During the defrosting work, the height of the blowing nozzle 100B of the dew-blowing means 100 installed on the vehicle body 2 in advance or afterwards is adjusted in accordance with the height of the tea plantation. When adjusting the height, the body 2
Blower 1 for dew removal for stays provided on the side
You can do this by changing the mounting position of 00,
Further, it can also be performed by changing the directional angle of the nozzle 100B described later. If the pointing direction is not changed, air is discharged from the opening 100B from the blower 47 via the bellows hose 100A. Since the opening has a flat cross section,
The discharge pressure is increased by the squeezing effect, and dew adhering to the tea leaves can be efficiently blown off.

On the other hand, when the direction of the opening of the blower nozzle 100B can be adjusted, the direction of the opening is adjusted so that the dew adhering to the tea leaves can efficiently slide on the surface of the tea leaves. Of air. When adjusting the direction of the opening of the blowing nozzle 100 </ b> B, it is preferable to set the angle so that the blown dew does not reach the plucking device 4. The direction of the opening can be set to the plucking device 4 side or the side opposite to the plucking device 4 side.

When the plucking operation of the tea leaves is started by the plucking device 4, the dew of the tea leaves to be cut is released, so that the tea leaves do not adhere to the cutting blade 43 and clog the cutting edge. When the extracted tea leaves are introduced into the transport duct 6 from the cutting blade 43 of the plucking device 4 by the air discharged from the nozzle 49, the tea leaves are transported without adhering to each other. .

Inside the transport duct 6, the pressure from the nozzle 49 acts on the tea leaves at the bend portion 61 located on the side of the plucking device 4, so that the tea leaves are bent by the centrifugal force.
1 moves along a curved surface 61A1 having a large radius of curvature.
In particular, such an operation is affected by the direction of the opening of the nozzle 49. The moving speed of the tea leaves that have passed through the bend portion 61 may decrease due to the pressure loss generated in the airflow when passing through the bend portion 61. However, in the present embodiment, since air is discharged from the air discharge nozzle 63 provided near the bend portion 61, the speed drop is corrected, and the tea leaves that are about to fall due to the speed drop ride on the rising airflow again. It is accelerated and continues to climb. The tea leaves that have moved in the transport duct 6 pass through the bend 62 on the tea leaf housing means 5 side and are discharged into the container 54 from the upper opening of the container 54.

As the plucking operation proceeds, the container 54
When the number of tea leaves accommodated therein increases and becomes full, the tea leaf plucking machine 1 is moved to a place where the transportation means T (see FIG. 6) is on standby, and the tea leaves in the container 54 are transferred. In this case, the state shown in FIG. 6 is obtained. That is, when the lift plate 51 rises in conjunction with the contraction of the lift cylinder 52 and stops at a predetermined position, the horizontal drive cylinder 53 extends,
The container 54 is positioned above the transportation means T. When the container is positioned above the transporting means T, the opening / closing cylinder 55 extends, and in conjunction with this, the chain 56 is extended to open the bottom cover 54A of the container 54, and the stored tea leaves are transported by the transporting means T. Fall towards.

According to the present embodiment, the blowing means 10
No. 0 allows not only to install the bellows hose 100A and the blowing nozzle 100B in advance but also to retrofit it to the existing vehicle body structure, and furthermore, it is possible to make the structure substantially the same as the blowing means 49. The cost can be prevented from increasing by sharing the data. In addition, since the air blowing means 100 can be retrofitted to the vehicle body 2 having an existing structure, it can be easily installed on the vehicle body without a special structure. It is possible to obtain a configuration in which dew payment can be reliably performed on the entire tea garden without raising the tea plantation. In the above-described embodiment, the self-propelled type configuration using the rubber crawler 33 as the type of the traveling device 3 is intended. However, the present invention is not limited to this configuration, and includes a rail or a caterpillar and wheels. It is also possible to use a self-propelled type, a traction type, a large riding type or a simple riding type.

[0033]

According to the first and second aspects of the present invention, the tea leaves to be plucked are blown by the blow-off means for blowing, which is adapted to the height of the tea tree. Can be reliably removed. In particular, since dew can be removed by a device used for plucking tea leaves for the entire tea plantation, all the tea leaves can be reliably removed without any special preparatory work or facilities in the tea plantation. In addition, according to the second aspect of the present invention, it is possible to provide an air blower for expulsion not only in front of the plucking device but also in the rear of the plucking device. This can be performed during the previous stage of the plucking operation, and the efficiency of the dew-off operation can be improved.

According to the third and fourth aspects of the present invention, by providing a structure having an opening for directly blowing air to the tea leaves in the air blower, the dew adhering to the tea leaves can be efficiently removed. In particular, by using a single nozzle or a plurality of nozzles, the area in the width direction of the tea ridge can be collectively or separately divided into a plurality of areas so that dew can be removed. In addition, when the opening is made flat, the dew can be almost immediately removed by increasing the discharge pressure of the air so that the dew can be efficiently blown off. Thereby, it is possible to stabilize the behavior of tea leaves at the time of plucking and at the time of transportation after plucking,
The plucking efficiency can be improved.
