Description

[Detailed Description of the Invention] In the conventional Mokusuri-type tea leaf drop collecting machine, a support for the tea leaf plucking body or tea leaf droplet collecting body is suspended from the vehicle body using a spring or the like, and the tea leaf droplet collecting body or the tea leaf droplet collecting body is suspended from the car body by a spring or the like. An operation handle is provided on the support, and the driver and assistant operate the handle visually and manually according to the top surface of the tea ridge and the irregularities of the ground. As the driver and his assistants are constantly working on their nerves to detect the droplets of tea leaves, the driver and his assistants are constantly straining and are very fatigued. This requires the consent of the assistant and the assistant, and depending on the relationship between the opposing workers, the work may be difficult, such as worsening the work efficiency.
As a result, the work efficiency is poor, and the quality often deteriorates due to the mixing of old leaves into the tea leaves, resulting in many problems with productivity.

Therefore, in view of the above-mentioned drawbacks, the present invention has been developed in order to eliminate the defects by installing a stabilizing plate along the rear of the bottom plate of the tea leaf picking machine to widen the bottom surface of the tea leaf picking machine. A tea ridge copying roller is installed in front of the tea ridge so that it can be adjusted up and down, and the front and back of the tea straw plucking mechanism inside the machine is supported by the tea ridge copying roller and the machine lotus bottom plate with a stabilizing plate. Then, the mechanism is elastically suspended from the gate-shaped frame of a power mobile vehicle using the elastic strips of a winding device with a clutch, and the tea leaf droplet collection with a roller for copying the tea ridges is transferred to the tea ridges by the winding device with a clutch. Work is carried out by moving the machine forward along the top surface, and at this time, the tea leaf plucking mechanism is appropriately supported by the tea ridge copying roller and the machine bottom plate with a stabilizing plate, so that the tea leaf plucking mechanism is always aligned with the top surface of the tea ridge. In addition to keeping the tea leaves in a constant state and not picking them at a certain depth, the depth of the tea leaf drop detection can be arbitrarily selected by adjusting the tea ridge copying roller up and down. ``On the other hand, the quality of tea can be improved without leaf contamination.

Next, its effect will be explained.

When the prime mover 8 starts operating, the drive wheels 3 rotate in the direction of the arrow in FIG.
It passes through the take-out gutter 34 and is blown out from the outlet 35 toward the rear. Therefore, with the machine straddling the tea ridges, the wheels 2 and 3
and 5 are placed between the tea furrows on both sides, and the leaf collection bag 48 is hung between the tea furrows on the first side.

Therefore, the hoists 12 and 13 are operated to vertically adjust the lifting platform 22 and the other side of the tea leaf plucking body b via the elastic strips 24 and 37, and the bottom of the mechanism 26 and the stabilizing plate 28 are moved to the upper surface of the tea ridge. Align with the first half. On the other hand, the bolts 42 and 45 are operated according to the state of the buds on the upper surface of the tea ridge, and the horizontal pestle 41 is moved back and forth, and the vertical village 44 is moved up and down, respectively, so that the left and right rollers 46 are aligned with the bottom plate of the spindle 26. At the same time, as shown in FIG. 4, the tea leaf plucking body b is placed at an appropriate position in front of the tea cake bridge picking body b, and the front part of the tea leaf picking body b with the tea ridge copying mechanism d is supported by the roller 46 on the tea ridge, and the receiving blade 31 Optimize the vertical position with respect to the upper surface of the brown ridge. When the operator rides the machine and operates it, the seat 49 is attached to the mounting tube 19 as shown by the dotted line in FIG.
When the operator is seated on the machine while walking, the operator stands in front of one side of the machine and starts operating the machine to move it forward. The tea straw picking body b with mechanism d has its roller 46 and machine 2.
The bottom plate with the stabilizing plate 28 of 6 supports the front and back of the tea comb probe b with the tea ridge copying mechanism d along the upper surface of the tea ridge, and keeps the receiving blade 31 of the spindle 26 in a constant state with respect to the upper surface of the tea ridge. The roller 46 rolls on the brown ridge while maintaining the stability plate 2 of the machine weight 26.
Stroke the top of the brown ridges with the bottom plate.

Therefore, one and a half tea leaves on the upper surface of the tea ridge are uniformly probed from the base of the petiole of new tea leaves along the shape of the upper surface by the joint between the blades of both twisted plates 30 and the receiving blades 31, and at the same time are "plucked". The tea leaves are pushed into the machine cliff 26 by both twisted plates 30 and fall onto the rear part of the bottom plate, and are conveyed to the first side by the blades 33 of the chain 32 that rotate one after another and fall into the takeout gutter 34. The straw collection bag 48 is removed from the outlet 35 by the air blown from the air pipe 38.
It is blown inside and contained. At that time, even if the ground is uneven or the top surface of the brown ridge is slightly uneven, the elastic strips should be adjusted accordingly.
4 and 37 expand and contract, and the tea leaf bridge body b with the tea ridge copying mechanism d always follows the upper surface of the tea ridge, and the receiving blade 31 is kept in a constant state with respect to the upper surface of the tea ridge.

When the machine reaches the end of the tea ridge after picking tea millet on one half of the tea ridge, change the direction of the machine and return to the pond side half of the tea ridge in the same manner as above. The tea leaves on the other half of the upper surface of the tea furrow are picked uniformly along the shape of the tea furrow, and the masterpiece of dripping tea leaves from the tea furrow is completed.

Note that the roller 46 of the brown ridge copying mechanism d described above functions in the same manner even if it is attached to the sparrow 26 so as to be vertically adjustable.

Further, one or more rollers 46 may be provided, and the rollers 46 may be in the shape of a chain. The stabilizer plate 28 of the cliff 26 may be formed separately from the bottom plate of the cabin 26.

On the other hand, a crawler may be attached to the axle 4 instead of driving the idling wheels 5 or the driving wheels 3 of the propelling body, and a clipper type instead of the rotary chaoi-drop probe b. The same effect can be achieved even if a horizontal rotary blade type tea leaf picker is installed.

In the present invention, since the Mekusuri-type tea straw drop detector is configured as described above, even if the ground is uneven or the upper surface of the tea ridge has some height, the elastic strips for suspending the tea leaf plucking body can be adjusted accordingly. The teacup picking body with a roller that expands and contracts constantly moves along the upper surface of the tea ridge.

Therefore, by winding up the foundation strip of the winder, the bottom surface of the tea leaf droplet sample can be aligned with the top surface of the tea ridge, and there is no need for fine adjustment by hand of the teacup picking body during work, and only one operator is required. In addition to being able to perform the deep plucking work of tea holly, it does not require any skill to extract the tea holly from the bottle, and the operator can cut forward while looking at the traces of tea leaves, making it easy to operate the machine and operate the machine for long periods of time. Driver fatigue is reduced during work, improving work efficiency. In addition, the base area of the tea leaf droplet collection is made wider by the mechanical bottom plate and the stabilizing plate behind it, so that it always rests on the hard old leaves that remain after the tea leaves have been plucked, and the roller and the above-mentioned mechanical lotus stabilizing plate are provided. The tea leaf plucking body advances while supporting the front and back of the tea leaf plucking mechanism with the bottom plate, and the tea leaf plucking mechanism probes the tea leaves, so the tea leaf plucking mechanism is always kept in a constant state with respect to the upper surface of the tea ridge. In addition, the rollers at the front of the tea basket can be adjusted up and down, so by adjusting the loaf up and down according to the condition of the buds on the upper surface of the tea ridge, the front part of the tea ridge can be raised and lowered to increase the depth of tea leaf plucking. Even if the tea leaves are locally thin and uneven on the upper surface of the tea ridge, the bottom plate with a stabilizing plate on the edge of the tea straw droplet can be used to ensure that the tea leaves are still intact. Because it rests stably on the hard old leaves over a wide area, the loaf in front of the machine does not sink into the tea furrow, and the tea leaves are plucked to a certain depth for deep cutting! The quality of the tea can be improved because only the new buds of the tea leaves are detected and no old leaves are mixed into the tea leaves.

Furthermore, since the rollers rotate, there is no frictional resistance against the tea ridges, which allows for better progress in picking the tea straw. It has a simple structure and can be manufactured easily and inexpensively, and its operation is light and smooth with few failures.
