When the sled 18 is placed on the ground and the worker on one side holds the bundle 20 to support the support, and the worker on the other side lifts the bundle 16, the plucking machine a can be supported at an appropriate height. can.

After that, when the operator on the other side operates the bundle 16 up and down, the plucking machine a moves up and down using the horizontal rod 33 as a fulcrum, and the other side of the plucking machine a moves up and down, and when the worker on the other side operates the bundle 16 back and forth, the plucking machine a rotates back and forth about the pin 34 as a fulcrum, and the state of inclination of the plucking machine a relative to the direction of the brown furrow 36 changes.

On the other hand, when the elevating bundle 24 is rotated in one direction or the other, the adjuster 27 moves up and down along the main rod 17 via the hoist 25 and the rope 26, and one side of the plucking machine a moves up and down. When the adjusting bolt 32 is screwed in or unscrewed, the mounting piece 30 with the plucking machine a rotates about the horizontal shaft 31, and the angle between the plucking machine a and the upper surface of the brown ridge can be adjusted as required.

Furthermore, when the worker on the l side lifts up the bundle 20, the supporting tool a rotates clockwise in FIG. When the bundle 20 is pushed down, it rotates counterclockwise in FIG. 1 using the front end of the support sled 18 as a fulcrum, and the plucking machine a descends.

Therefore, depending on the height and width of the brown furrow 36, the height and ease of use of the worker, etc., the hoist 23 is moved by the lifting bundle 24 as appropriate.
The operator on the ■ side moves the bundle 20 up and down and fixes the tightening using the lever 22. , the worker on the other side moves the bundle 16 left and right and up and down to fix it in an appropriate position, and the two workers each hold the bundle 20.16 in a comfortable position and move the support and the picking machine a. When supported, the bottom plate 2 of the plucking machine a is adjusted so as to substantially lie along the side half of the upper surface of the brown furrow 36.

On the other hand, when the prime mover 14 starts operating, the wind turbine shaft of the blower 15 rotates together with the driving shaft, and the blower 15 generates air, which is blown into the exhaust pipe 12 and harvested from the exhaust port 13. At the same time as the air is ejected onto the body 11, the cutting body 11 is driven from the wind turbine shaft of the blower 15 via a transmission mechanism.

Therefore, two workers stand on both sides of the tea furrow, are positioned almost parallel to each other, and place the bottom plate 2 of the plucking machine a on the upper surface of the tea furrow 36 on one half of the first side.The worker on the waist 1 side holds the handle 20 While pulling back, the plucking machine a is moved forward without the operator on the other side accompanying.

At this time, depending on the unevenness of the ground, the shape of the upper surface of the brown furrow 36, unevenness, etc., the operator on the first side moves up and down while pulling the grinder 20 to adjust the overall height of the picking position of the brown furrow 36. , the worker on the other side picks the tea furrow 36 using the other side of the plucking machine a.
While checking the plucking depth near the center, move the bundle 16 up and down so that the bottom plate 2 of the plucking machine a is aligned with the first handle part on the top surface of the brown furrow 36.
On the other hand, the bundle 16 is moved back and forth according to the arc shape of the upper surface of the brown furrow 36, and the inclination state of the plucking machine a with respect to the direction of the brown furrow 36 is changed, so that the arc shape of the bottom plate 2 of the plucking machine a is changed to the arc shape of the brown furrow 36. If you move the machine forward along the tea furrow 36 while aligning it with the upper surface of the tea furrow 36, and stroke the upper surface of the tea furrow 36 with the bottom plate 2 of the plucking machine a, the tea confections on the upper surface of the tea furrow 36 will be removed. The new tea confections are uniformly picked from the base of the petiole by the cutting body 11 along the top surface shape, irregularities, curves of the tea ridges, etc., and at the same time, the picked tea confections are swept into the machine case 1 by the blowing air from the exhaust port 13. blown into the
The leaves are blown into the leaf collecting bag 35 from the rear outlet and stored therein.

After the tea leaves have been plucked from the first part of tea furrow 36,
When the machine changes direction and reverses left and right, and returns while operating the other half of the tea ridge 36 in the same manner as above, the tea leaves on the other half are uniformly picked along the shape of the tea ridge 36. Then, the plucking work of the brown furrow 36 is completed.

On the other hand, when attaching the support of the present invention to a conventional two-piece portable tea leaf plucking machine, fix the bolts that fixed the side plate and bottom plate on the machine casing 1 side of the plucking machine, the side plate and top plate, and the front and rear rods. After removing the bolts and nuts and removing the side plate and the U-shaped 1-side nozzle, as shown in FIG. Fix the bottom plate 2 with bolts 6, and tighten the top plate 7 and front and rear rods 8 with nuts 9.
By fitting the mounting tube 4 of the base plate 5 into the horizontal rod 33 of the support, the support can be attached to a conventional two-piece portable tea leaf plucking machine.

Note that the attachment tube 4 may be attached to the machine casing 1 using other structures.

Further, instead of the plucking machine a provided with the clipper-type reaping body 11 described above, the device of the present invention may be applied to a plucking machine provided with a rotary set or a horizontal rotary blade type reaping body, and the same effect as described above will be obtained.

On the other hand, the tea leaf plucking machine of the present invention can also be used for plucking buckwheat, chiso, etc. in the same manner as described above.

The support device for the tea leaf plucking machine of the present invention has the following remarkable effects.

(1) Since the support is manually operated and not mechanical, anyone can use it safely.

(2) Since the sled is a round bar, it is strong and has low ground resistance, making it easy to operate the machine such as turning.

(3) The support is simply a rod-shaped sled attached to the lower end of the main rod, and a work bundle and hoist attached to the upper end, so it is lightweight and easy to carry, and can be used smoothly even between narrow tea furrows. It has a wide range of use, and is easy to operate.

(4) Even during plucking work, the worker on the first side turns the lifting bundle of the hoist with one hand, and the plucking machine height adjuster moves along the main rod, allowing the plucking machine to move up and down smoothly. The height above the ground can be adjusted arbitrarily, making it convenient for work.

(5) By operating the adjustment bolt of the plucking machine height adjuster according to the slope of the tea plantation and the model of the plucking machine to be installed,
The plucking machine can be rotated in the front-back direction to adjust the angle of the plucking machine with the upper surface of the tea ridge as required, and the plucking machine can be rotated upwardly but not downwardly in the adjusted state as described above. Therefore, depending on the shape and unevenness of the upper surface of the tea ridge, the bottom plate of the plucking machine is always adjusted appropriately to the upper surface of the tea ridge, and the bottom plate of the plucking machine is rotated upward at will to make fine adjustments while working to obtain a good tea cake. Only the new leaves are picked, and the quality of the tea can be improved since no old leaves are mixed into the tea confectionery, and it is easy to handle, reducing worker fatigue and improving work efficiency.

(6) The structure is simple and can be manufactured easily and inexpensively.
