2. Description of the Related Art Conventionally, the present applicant has proposed a rail type tea leaf plucking machine A as shown in FIG. This well-known rail type tea leaf plucking machine A is a gate type frame C that straddles a tea tree ridge B.
Left and right legs D, D of the front and rear wheels E, E forming a pair at the lower end of D
The left and right wheels E, E are rollingly contacted with the left and right rails F, F laid between the ridges on both sides of the tea tree ridge B to freely travel in the front-back direction while straddling the tea tree ridge B. It constitutes a traveling carriage G.

A plucking machine J is suspended by a support frame I that hangs from the horizontal center of the horizontal frame H of the gate frame C so that it can move vertically, horizontally and vertically. This plucking machine J is provided with a prime mover K and a cutting blade drive unit L near the center, and is provided with a cutting blade M extending from the cutting blade drive unit L to one end side of the tea tree ridge B in an arc shape. The lower end of the support frame I is supported by the plucking machine J so as to be vertically movable, horizontally rotatable, and vertically rotatable relative to the inner portion of the prime mover K.

The plucking machine J is horizontally rotated by the support frame I, and the outer end of the cutting blade M is locked to one leg D of the gate frame C or the other leg D. A vertical adjustment handle O is provided for vertically adjusting the outer end side in a state of being locked to the portions N and N and the outer end portion thereof being locked.

A rail type tea leaf plucking machine A having the above-mentioned structure
When performing tea leaf plucking work by means of the support frame I, the plucking machine J is moved up and down with respect to the upper surface of the tea tree ridge B, and the outer end of the cutting blade M is provided on one leg D of the portal frame C. The cutting portion is locked to the locking portion N, and the vertical adjustment handle O vertically moves the outer end side of the cutting blade M (the hem side of the tea tree ridge) to adjust the plucking depth of the cutting blade M for the tea tree. A tea leaf storage bag is attached behind the cutting blade M.

Then, the gate-shaped frame C is moved (forward) along the tea tree ridge B in one direction, and the cutting blade M plucks half (one side) the tea leaves of the tea tree ridge B. Gate-shaped frame C is tea tree ridge B
When the end is reached, the plucking machine J is horizontally rotated by the support frame I and turned left and right, and the outer end of the cutting blade M is moved to the portal frame C.
Of the cutting blade M by engaging with the engaging portion N provided on the other leg D of the blade, and moving (returning) the gate-shaped frame C in the opposite direction.
The other half of the tea leaves of the tea ridge B is plucked.

[0007]

By the way, in the above-mentioned conventional rail type tea leaf plucking machine A, the plucking machine J is mounted on the lower end portion of the support frame I hanging from the lateral center of the horizontal frame H. The inner part of K is hung so that it can move vertically, horizontally and vertically, and when the tea ridge B is in a flat place and there is no difference in height between the tea ridge B on the left and right, it is plucked. Since the growth of the tea leaves is almost uniform over the entire surface of the tea ridge B, the gate-shaped frame C is reciprocally moved, and the plucking machine J is horizontally inverted in the forward and backward paths to cut the cutting blade M.
Therefore, when plucking tea leaves, there was almost no need to adjust the plucking depth on the hem side, and there was no problem because there was no plucking step at the center of the tea tree in the left-right direction.

However, as shown in FIG. 5, when the tea tree ridge B is inclined by α ° with respect to the horizontal line P and the tea tree ridge B has a difference in height between the left and right sides, the tea tree ridge B is generally associated with the sunlight.
The bottom of the slope below (valley side = left in the drawing) has stronger tree force than the bottom of the slope above (mountain side = right in the drawing), and the growth of branches and leaves is faster. Therefore, the skirt on the valley side is higher than the skirt on the mountain side.

When the tea tree ridge B in such a state is plucked with the rail type tea leaf plucking machine A, for example,
First, the half on the valley side is plucked, and then the half on the mountain side is plucked. At this time, the vertical adjustment depth on the outer end side of the cutting blade M differs between the valley side and the mountain side, and the vertical adjustment width Q is generated. However, there was a problem that a pruning step could be formed in the central part of the tea tree ridge B in the left-right direction. Particularly, in the rail type tea leaf plucking machine A, the plucking depth of the tea leaf is adjusted in units of several mm, so that a step at the central portion of the tea tree ridge B is a big problem.

Further, the plucking machine J is provided at the lower end portion of the support frame I which is hung from the horizontal center of the horizontal frame H.
Since the inner part of the prime mover K is suspended, the cutting blade M
There was also a problem that when the tea bag storage bag was attached to and detached from the rear of the, the supporting columns for suspension hampered and it took time to replace.

The present invention has been made in order to solve the above problems, and by changing the support position of the plucking machine by the support frame, the tea leaf plucking depths on the left and right hem sides of the inclined tea tree ridge are changed separately. Even if the tea leaf plucking depth in the central portion of the tea plant is almost constant, there is no step, and the tea leaf accommodating bag can be replaced easily and in a short time. The purpose is to

[0012]

In order to achieve this object, the present invention provides: Wheels are installed at the lower ends of the left and right legs of the gate-shaped frame that straddles the tea tree ridge, and the wheels on the left and right are transferred to the left and right rails laid between the ridges on both sides of the tea tree ridge to straddle the tea tree ridge. And a traveling carriage that freely travels in the front-back direction, and is suspended vertically and horizontally and vertically by a support frame from approximately the center of the gate-shaped frame in the left-right direction, and the prime mover and cutting blade drive closer to the center. And a pruning machine provided with a cutting blade that extends in an arc shape from the cutting blade driving part to one end side of the tea tree ridge, and the plucking machine is horizontally rotated by the support frame to cut the end of the cutting blade. Has a locking means for vertically adjusting the gate part to one side or the other side of the portal frame, and reciprocates the portal frame to pluck the tea leaves of the tea ridge half by half with a cutting blade. In the rail type tea leaf plucking machine, the above plucking machine Move up and down around the cutting blade driving section,
It is characterized in that it is supported by a support frame so as to rotate horizontally and vertically.

.. The support frame supports a portion of the plucking machine that is closer to the outside of the prime mover.

[0014]

By adopting such means, in the method for supporting a plucking machine in a rail type tea leaf plucking machine according to the present invention, the plucking machine moves vertically, horizontally and vertically about the cutting blade drive section. Since it is supported by the support frame, the cutting blade drive part is rotated when the plucking machine is horizontally rotated, even when the tea leaf plucking depths on the left and right hem sides are adjusted separately. , The tea leaf plucking depth in the central part of the tea tree is almost constant, and there is no step.

Further, since the supporting frame supports the portion of the plucking machine that is closer to the outside of the prime mover, the supporting frame does not get in the way when the bag for storing tea leaves is attached to and detached from the rear of the cutting blade, and replacement is easy. It can be done easily and can be attached and detached in a short time.

There are wide and narrow variations. Therefore, in the rail type tea leaf plucking machine 1 of the present embodiment, when the mutual distance between the pipe rails 8 is a standard 180 cm, the gate frame 3 of the traveling carriage 4 forms a standard gate shape.
When the mutual spacing between the pipe rails 8 is wider than the standard, the gate-shaped frame 3 bends downward at the center in the left-right width direction, and when it is narrower than the standard, the gate-shaped frame 3 bends upward at the center in the left-right width direction. . That is, the portal frame 3 is configured to be bendable up and down with the connecting pins 17, 17 set at the center in the left-right width direction as bending points, and the pair of left and right support stays 22, 22 arranged front and rear, and the slides. Prop 1
Connecting metal fittings 2 that can slide vertically relative to 9 and 19
Since it is linked to the left and right via 0 and 20, it can be bent up and down while maintaining a symmetrical shape without falling in the left and right direction.

Then, according to the refraction of the gate-shaped frame 3, the mutual distance between the left and right driving wheels 6 and 6 and the driven wheels 7 and 7 is adjusted at any time by following the width of the mutual distance between the pipe rails 8 and 8. Therefore, the rail type tea leaf plucking machine 1 according to the present embodiment can be used even in another tea plantation where the distance between the pipe rails 8 and 8 varies widely, and also when the distance between the pipe rails 8 and 8 is partially wide. If there is, it can be used respectively.
