In addition, in a pruning machine that performs pruning while ascending and rotating a chain saw raised above the machine body in a spiral manner,
This invention relates to a lock position of a chain saw in a pruning machine that enables suitable pruning by suppressing unnecessary movement of the swinging part of the machine body on which the chain saw is set upright.

て枝打を行なう枝打機がある。Prior Art Conventionally, a machine body swinging section is configured to rotate around a drive shaft that is transmission-connected to a drive wheel, and the machine body swinging section is equipped with a prime mover, a transmission mechanism, a chain saw, and a link between the trunk and the chain saw. Branches are pruned by being equipped with a stopper to regulate the gap, etc., transmitting the power of the prime mover to the chain saw and drive wheels through a transmission mechanism, and by rotating and raising the chain saw in a spiral manner using an appropriate method. There is a chance to hit.

や枝切断跡と干渉させることなく下降するように
構成されている。 In this type of pruning machine, when the machine moves up by transmitting rotational force from the prime mover to the drive wheels, the swinging part of the machine receives the transmitted reaction force and approaches the trunk side, and the machine descends. At this time, the prime mover acts to reverse the drive wheels, so the swinging parts of the aircraft receive a transmission reaction force opposite to that when rising, and move away from the trunk, moving to a predetermined position and being regulated. Ru. In this way, the branch cutting machine brings the chain saw close to the trunk to cut branches near the trunk when ascending, and moves the chain saw away from the trunk when descending to descend without interfering with the bumps or branch cut marks on the trunk. It is configured as follows.
ところで、機体の走行に必要な駆動力は通常の
場合には原動機の動力により得られるが、下降時
にあつては機体の重力のみによつて下降する場合
があり、この場合には動力が駆動輪から原動機へ
逆流する現象を生じる。かかる状態では機体揺動
部に作用する伝動反力は機体揺動部を幹側へ動作
させるように作用するので機体揺動部は位置不安
定となつてブラブラすることになり、チエンソー
と幹との干渉を誘発することがある。 By the way, the driving force necessary for the aircraft to travel is normally obtained from the power of the prime mover, but when descending, there are cases where the aircraft descends only due to its gravity, and in this case, the power is transferred to the drive wheels. This causes a phenomenon where the flow backs up from the engine to the prime mover. In such a state, the transmission reaction force acting on the machine's swinging part acts to move the machine's swinging part towards the trunk, causing the machine's swinging part to become unstable and wander, causing the chainsaw and trunk to may cause interference.
そしてまた、そのような状態で下降している時
に駆動輪或は遊動輪等が幹のこぶや枝切断跡に当
たつて機体の自重だけでは降下しなくなると、今
後は原動機の動力によつて駆動輪を回転させるの
で原動機から駆動輪への動力伝動による伝導反力
が機体揺動部へ作用して機体揺動部は幹から再び
離反する。 Also, if the drive wheels or idle wheels hit a bump in the trunk or a trace of a branch cut while descending in such a state, and the aircraft is no longer able to descend under its own weight, it will no longer be able to descend due to the power of the prime mover. Since the drive wheels are rotated, a reaction force generated by power transmission from the prime mover to the drive wheels acts on the swinging part of the machine body, and the swinging part of the machine body separates from the trunk again.

ある。 In this way, especially when the pruning machine is descending, the swinging part of the machine body repeatedly approaches and separates from the trunk, so the swinging part of the machine body makes unpleasant noises when swinging, and also generates vibrations and becomes unstable. This causes problems such as damage to the trunk caused by chainsaws and the aircraft falling off its wheels.

着してなる点にある。Structure of the Invention The locking device for the chain saw position in the pruning machine according to the present invention is characterized by the fact that the chain saw is installed upright on the upper part of the machine body swinging part with the rotation center around the substantially vertical drive shaft. During the ascent of the aircraft, pruning is performed by bringing the body swinging section close to the trunk and rotating the chain saw spirally upward along the trunk, and while the machine is descending, the body swinging section is moved close to the trunk. In the pruning machine configured to lower the chain saw away from the trunk without interfering with the trunk, an engaging body that is integral with the body fixing part is loosely inserted into a guide groove of a lock lever pivotally connected to the body swinging part. Fit it,
A locking groove into which the engaging body is fitted when the body swinging portion is separated from the trunk is continuously formed on the side opposite to the pivot point of the guide groove, and a locking groove is formed on the opposite side of the pivot point of the lock lever. The point is that a spring is installed that pulls the shaft toward the opposite side of the trunk.

得る利点がある。Effects of the Invention According to the present invention, the engaging body protruding from the fuselage fixing part is fitted into the guide groove of the lock lever pivotally mounted to the fuselage swinging part, and the engaging body protruding from the fuselage fixing part is fitted into the guide groove of the lock lever pivotally connected to the fuselage swinging part, and By continuously forming a locking groove into which the engaging body fits when the moving part separates from the trunk, and by installing a spring on the side of the lock lever opposite to the pivot point to pull the part toward the side opposite to the trunk, While the aircraft is rising, one end of the lock lever is pulled by a spring, so the other end of the lock lever uses the engaging body as a fulcrum to push the aircraft swinging part toward the main body. In addition to the transmission reaction force caused by the power, it is subjected to the pressing force of the spring, further suppressing unnecessary movement, and when the aircraft switches from ascending to descending, the kinetic inertia of the transmission mechanism acts, preventing the aircraft from rocking. The transmission reaction force received by the main body is large, and this transmission reaction force is used to fit the locking body into the locking groove of the lock lever, so that the swinging part of the aircraft is reliably kept in a position away from the trunk while descending. It is in a locked state and can descend without rocking at all, which prevents the trunk from being damaged by the chainsaw, or the swinging parts of the aircraft approaching or moving away from the trunk. It has the advantage of being stable without producing unpleasant noises and reliably preventing the aircraft from falling off its wheels.
