Detailed Description of the Invention (a) Industrial Application Field The present invention relates to an automatic engine stop mechanism for a pruning machine, and in particular, the invention relates to an automatic engine stop mechanism for a pruning machine, and particularly to prevent the engine from accidentally stopping while the pruning machine is ascending or descending a tree trunk. (C7) Conventional technology Conventionally, there is a pruning machine that pruns the trunk while it is above the tree and automatically descends once the pruning reaches a predetermined height. However, in order to ensure work safety, this type of pruning machine is usually equipped with an automatic engine stop mechanism for automatically stopping the engine of the pruning machine when it has been lowered to a predetermined position.

７４５５４号公報参照）。To explain the outline of this automatic engine stop mechanism, a contactor extending from the micro-sinch as a sensor is displaced when it comes into contact with the ground or an object attached to the trunk, and the micro-sinch is activated by that displacement. The sensor emits a detection signal, which is received by an appropriate engine stop means and automatically stops the engine (for example, Utility Model Application No. 60-1).
(See Publication No. 74554).

されるという不都合がある。(C) Problems to be Solved by the Invention In this type of automatic engine stop mechanism, the contactor that comes into contact with the ground or an object attached to the trunk extends from the microswitch. While ascending and descending, a cut branch or an adjacent tree branch may inadvertently come into contact with the contactor, which causes the engine automatic stop mechanism to activate and cause the pruning machine to cut into an unintended location, i.e., in the trunk thread. It may stop. If such a situation occurs, it will take a lot of time and effort to recover the pruning machine, and the efficiency of the pruning work will be significantly impaired.

る。(d) Means for solving the problems The means taken by the present invention to solve the above problems are as follows:
As shown in FIG. 1 corresponding to the embodiment, a pruning machine is used which raises and lowers a trunk (4) along its surface using the power of an engine (2) installed in a machine body (5). (
4) A magnetic sensor (9) that detects the magnetic body (16) on the surface; and a magnetic sensor (9) that detects the magnetic body (16) and activates the engine (2) in response to a sensing signal generated by the magnetic sensor (9). The engine is characterized by being provided with an engine stopping means for stopping the engine.

不慮のエンジン停止は起こり得ない。(E) Even if a cut branch or an adjacent tree interferes with the magnetic sensor (9) while the pruning machine is ascending or descending, the interfering branch must not be made of magnetic material. Therefore, the magnetic sensor (9) does not emit a sensing signal, and therefore, an unexpected engine stop as in the conventional case cannot occur.

When the engine stop means receives the signal, the engine (2) is automatically stopped and the aircraft (5) stops moving.

停止する。(9) is a magnetic sensor fixed to the fuselage (5), and the sensitivity is increased by having its sensing part directly facing the surface of the trunk (4) and as close as possible to the surface of the trunk (4) as long as there is no problem. It is preferable for increasing. This magnetic sensor (9) works in conjunction with engine stopping means to stop the engine (2). An example of the engine stopping means is shown in Fig. 3 in the case where the engine (2) is a spark ignition type engine. explain. That is, (10) is a contact that closes in response to a sensing signal generated by the magnetic sensor (9), and serves to ground the primary coil (12) of the electric ignition device (11). (13) is a spark plug connected to the secondary coil (14), and (15) is a power generator that supplies power to the primary coil (12), which is driven by the rotation of the engine (2). Now, when the contact (10) closes, the primary current is cut off, the induction effect of the primary coil (12) is not obtained, and high voltage is not induced in the secondary coil (14), so the spark plug (13) is closed. ) becomes unable to discharge and the engine (2) stops.
