行われるのである。The double-sided trimming machine for tea trees having such a structure is used for cutting both opposite hem portions of the tea tree rows on both sides of the ridge of the tea tree in one operation. Tea trees are plucked about 2 to 4 times a year, and during each pruning period, plant surface mowing to prevent mixing of old leaves at the time of pruning and shallow mowing to establish tree vigor are carried out. However, the annual growth of about 5 to 10 cm is observed, and the hem of the tea tree also shows a large spread, which narrows the furrows, making it inconvenient for work such as plucking tea plants, fertilizing tea plants, spraying chemicals, and deep plowing of furrows. Since it is given, both sides are trimmed.

ることができるものである。In such double-sided hemming work of tea trees, the double-sided hemming machine of the present invention is such that the operator grips the handle 5 and positions the wheel 7 between the ridges of the tea tree and pushes the machine body forward while pressing the left and right cutting blades 4 When cutting the hem of the tea plant on both sides by
However, since it is mounted at the central portion of both cutting blades 4, that is, the central portion in the lateral direction of the machine body, the lateral balance of the machine body is good and the maneuverability is good. Also, when adjusting the cutting width of the cutting blades 4 and 4 according to the distance between the left and right tea plants, regarding the upper distance,
The slider shaft 20 is rotated by grasping the knob 21 and rotating it clockwise or counterclockwise, and the screw threads 16 and 17 at the upper end of the crankcase 3 that mesh with the screw threads 18 and 19 simultaneously move to the left or right to mow. The blade bodies 4 and 4 approach each other or are separated from each other so that the spacing can be adjusted easily and easily. Further, the interval of the lower part of the cutting blade body 4 is arbitrarily adjusted by rotating the slider bolts 15 and 15 by the cutting blade opening angle adjusting plate 22 and the cutting blade opening angle adjusting screw 23. Therefore, the distance between the cutting blades 4 and 4 and the opening degree (inclination angle) with respect to the tea plant can be adjusted more freely than in the conventional case, and the conventional drawbacks can be completely eliminated.
なお、クランクケース３，３の移動手段は、上記実施例
に限らず他の螺動手段でもよい。The moving means of the crankcases 3, 3 is not limited to the above-mentioned embodiment, and other screwing means may be used.
以上説明したように、本考案の茶樹用両面裾落し機は、
上述の構成を有するので下記の効果を奏し得るものであ
る。As explained above, the double-sided hemming machine for tea plants of the present invention is
Since it has the above-mentioned composition, the following effects can be produced.
．上フレームを兼ねる伝動ケースに設けたスライダー
軸をノブにより回転させるだけで、左右の刈刃体の間隔
を簡単，容易に移動調節することができる。また、ノブ
の回転により調節できるので、作業中でも調節操作が行
える。． By simply rotating the slider shaft provided on the transmission case that also serves as the upper frame with the knob, the distance between the right and left blades can be easily and easily adjusted. Also, since it can be adjusted by rotating the knob, adjustment operations can be performed even during work.
．また、刈刃体の間隔調節は、左右同時に同量ずつ行
われるから、機体重心はほとんど移動せず、機体の操縦
性，操作性が向上する。． In addition, since the distance between the cutting blades is adjusted by the same amount at the same time on the left and right, the center of gravity of the machine is hardly moved and the maneuverability and operability of the machine are improved.
．さらに、両刈刃体を同時に離間，接近移動させるの
で、調節時間が少くてすみ、また、相互に反対のねじ山
で噛合うので緩みも少し、構成も簡略化される。． Furthermore, since both cutting blades are moved away from each other and moved toward each other at the same time, the adjustment time is short, and since the mutually opposite threads engage each other, the looseness is a little and the structure is simplified.
