[Problems to be solved by the invention]
When the above-mentioned rail type traveling cart is equipped with a pruning machine to perform the pruning operation, the conventional pruning machine using the clipper-type cutting device has the following problems.
If the pruning work on tea plant is deepened, the rails laid in the ridges will be immediately buried by the pruning pieces due to the large cut pruning pieces falling in the ridges, and the traveling cart will not be able to move. There is.
[0005]
Due to this problem, conventionally, an operation method in which the depth of the pruning is made shallow and the pruning operation for one row of tea trees is reciprocated 4 to 5 times or more is adopted. According to such an operation method, there is a disadvantage that the operation efficiency is poor and the pruning operation requires a long time.

[Action]
The cutting rotor according to the present invention is a cylindrical type, which is a cavity in which only the rotating shaft is present within the radius of the rotating cylinder blade, so that the cut pieces cut by the cylinder blade and the receiving blade are: Due to the high speed rotation of the cylinder blade, it is carried around in the cavity and cuts twice and cuts three times, so that the pruned pieces are cut into small pieces and cut from the rear opening of the box frame. It will be released backwards.
[0015]
As a result, even if the pruning depth for the tea tree was increased, the pruned pieces were cut into small pieces and cut from the opening at the rear of the machine frame. Will be released.
In such a pruned piece that has been cut into pieces, the pruned pieces fall under the tea tree after passing between the leaves of the tea plant after the pruning operation, and the pruned pieces fall into the ridges. As a result, the phenomenon in which the rails laid between the ridges are not immediately buried by the pruning pieces does not occur, and the situation in which running is impossible is improved.

At the start of the work, the generator 6 is started, and the cutting height of the pruning rotor 4 is set by a switch provided on the control panel of the control box 7.
Next, the prime movers 49, 49 are started, the rotary cylinder blade 47 is rotated at a high speed, and the traveling rail truck travels. At this time, the branches of the tea tree are cut into small pieces by the cutting action of cutting twice and cutting three times by the high-speed rotation of the cylinder blade 47, and are discharged backward from the rear opening of the box-shaped machine frame 41. become. For this reason, it is not necessary to perform the operation of reciprocating 4 to 5 times or more of a row of tea ridges by making the depth of the pruning shallow and reducing the required pruning depth. As a result, the work efficiency can be greatly improvedWear.

The pruning rotor 4 configured as described above is disposed so as to straddle one hem side and the top of the tea tree ridge, and the prime mover 49 is mounted on the upper machine frame of the top, and is suspended from the traveling vehicle 12. The two front and rear suspension rods 4F, 4F are pivotally mounted on the part facing the top side of the upper surface of the tea tree ridge so as to be able to swing left and right around the axis in the front-rear direction, and the part facing the hem side has a handle. The screw shaft 4G is erected to be able to swing left and right.
[0035]
At the upper ends of the suspension rods 4F, 4F, a suspension bracket 4H is pivotably mounted around a longitudinal axis, and is inserted into the screw shaft 3G so as to be pivotable around a longitudinal pin. A nut 4I having a metal fitting is mounted. Therefore, in order to cope with these, the gate type frame 11 has a suspension motor 16 provided with a brake mechanism and a speed reduction mechanism controlled by the control box 7 and a pinion rack mechanism 17 driven by the suspension motor 16. The hanging bracket 4H is rotatably connected to the lower end of a rack shaft 17a that is driven in the vertical direction. On the other hand, the insertion fitting is connected to the lifting frame 11c.
[0036]
The single-sided rail truck equipped with the pruning rotor 4 configured as described above operates the hanging position adjustment switch of the control box 7 to drive the rack shaft 17a of the pinion rack mechanism 17 up and down. Then, the vertical position of one end of the pruning rotor 4 facing the top side of the tea tree ridge is adjusted, and the raising / lowering switch of the control box 7 is operated to raise and lower the lifting frame 11c. The vertical position of the other end of the pruning rotor 4 facing the side is adjusted, and the vertical position of the other end is finely adjusted by operating the screw shaft with the handle.
[0037]
Then, after adjusting the hanging position of the pruning rotor 4 in accordance with the upper surface on one side of the tea tree ridge to be worked, the traveling motor 15 is synchronously rotated by operating the forward traveling button of the control box 7 while driving the motor 9. Thus, the left and right drive wheels 13, 13 are rotationally driven in the forward direction. As a result, the left and right drive wheels 13, 13 and the driven wheels 14, 14 roll on the left and right rails laid between the ridges on both sides of the tea ridge, so that the traveling vehicle 12 moves forward at a low speed along the tea ridge. It travels, and in this process, the pruning operation is performed by the pruning rotor 4. At this time, the branches of the tea tree are cut into small pieces by the cutting action of cutting twice and cutting three times by the high-speed rotation of the cylinder blade 47, and are discharged backward from the rear opening of the box-shaped machine frame 41. become. For this reason, it is not necessary to perform the operation of reciprocating 4 to 5 times or more of a row of tea ridges by making the depth of the pruning shallow and reducing the required pruning depth. As a result, the work efficiency can be greatly improved as compared with the related art.

It is supported by a hydraulic cylinder 87 rotatably connected. The height of the pruning rotor 4 is adjusted by expanding and contracting the hydraulic cylinder 87 to adjust the pruning depth.
[0040]
As described above, the riding type tea garden management machine equipped with the pruning rotor 4 allows the management machine to enter the ridge over the tea ridge to be worked, and then operates the operation lever of the operation box 85 to reduce the hydraulic pressure. The depth of the pruning is determined by extending and retracting the cylinder 87, and the crawler traveling device 82 is made to travel forward while driving the motor 9 of the pruning rotor 4.
In this process, the pruning operation is performed by the pruning rotor 4, and the branch of the tea tree is cut into small pieces by cutting action twice and three times by the high-speed rotation of the cylinder blade 47. It is released from the rear opening of the frame 41 to the rear. For this reason, it is not necessary to perform the operation of reciprocating 4 to 5 times or more of a row of tea ridges by making the depth of the pruning shallow and reducing the required pruning depth.

As a result, even if the pruning depth for the tea tree was increased, the pruned pieces were cut into small pieces and cut from the opening at the rear of the machine frame. Will be released.
In such a pruned piece that has been cut into pieces, the pruned pieces fall under the tea tree after passing between the leaves of the tea plant after the pruning operation, and the pruned pieces fall into the ridges. As a result, the phenomenon in which the rails laid between the ridges are not immediately buried by the pruning pieces does not occur, and the situation in which running is impossible is improved.
[0047]
In addition, it is not necessary to perform the operation of reciprocating 4 to 5 times or more of the pruning operation for one row of tea tree ridges by reducing the depth of the pruning, and the operation can be performed with the required pruning depth. , The work efficiency is greatly improvedWear.
[0048]
Further, since the right and left rotors are separately driven in the left and right directions, the load at the time of cutting is distributed to the driving units on both sides, so that the weight of the pruning machine can be reduced.
[0049]
Further, since a separation metal fitting is provided between the right half and the left half of the rotor portion, there is no problem that uncut branches are generated even if there is some gap between the left and right rotor portions. .
