Изобретение относитс к оборудованию дн механизации лесозаготовительных работ, в частности к переносной моторной пиле, и может быть использовано как при валке деревьев, так и при раскр жевке стволов поваленных деревьев.The invention relates to the equipment for the mechanization of logging operations, in particular to a portable chain saw, and can be used both for felling trees and when chewing fallen tree trunks.

Известны переносные моторные пилы включающие двигатель, пильный аппарат и раму с высоко расположенными руко тками, снабженными амортизаторами и механизмом управлени двигателгм 1 ,Portable motor saws are known that include an engine, a sawing apparatus and a frame with highly positioned handles fitted with shock absorbers and an engine control mechanism 1,

В таких пилах через руко тки вибраци от двигател передаетс на моториста , что вызывает быструю утомл емость его и, в конечном счете, влечет за собой снижение производительности труда и профессиональные заболевани .In such saws, vibration is transmitted from the engine to the engine mechanic, which causes fatigue and ultimately leads to a decrease in labor productivity and occupational diseases.

известны также переносные моторные пилы, включающие двигатель,жестко соединенный с пильным аппаратом, и руко тку с механизмом управлени двигателем 2 .Portable motor saws are also known, including a motor rigidly connected to the saw apparatus and a handle with an engine control mechanism 2.

В этих пилах вли ние вибрации, воздействующей от двигат ел на моториста , доведено до уровн санитарных норм, но полностью не устранено,чтоIn these saws, the influence of vibration acting from the engine on the motor mechanic was brought to the level of sanitary standards, but not completely eliminated, which

также приводит со временем к профес сиональным заболевани м.also leads over time to occupational diseases.

Цель изобретени - иск.пючение вли ни вибрации на моториста и уменьшение загазованности в зоне расположени его при работе.The purpose of the invention is the elimination of the influence of vibration on the motor mechanic and the reduction of gas pollution in the area of its operation.

Поставленна цель достигаетс тем, что пила снабжена устройством дл жесткого прикреплени ее к ство0 лу дерева, имеющим когтевой захват с шарниром и замковым приспособлением , соединенный с нижней частью корпуса двигател при йомощи шарнирного рычага и преломл ющегос крон5 штейна с упором, обеспечивающих возможность поворота двигател с пильным аппаратс ч в двух взаимно перпендикул рных плоскост х, причем руко тка пилы соединена с корпусом двига0 тел при помощи гибких демпфирующих элементов и снабжена съемной ручкой с рычагом дистанционного управлени , соединенным посредством удлиненного троса с дроссельной заслонкой кар5 бюратора двигател .The goal is achieved by the fact that the saw is equipped with a device for rigidly attaching it to the trunk of a tree, having a claw grip with a hinge and a locking device, connected to the lower part of the engine body at the hinge arm and refracting crown of the matte with an emphasis, allowing the engine sawing machines in two mutually perpendicular planes, the saw handle being connected to the engine body by means of flexible damping elements and provided with a removable handle with a lever Remote control of which is connected by a cable to the elongate throttle kar5 byuratora engine.

Claims

FIG. 1 shows schematically a portable motor-saw, side view in the positions for felling and cutting (continuous line) and when cutting the root system (dotted line); Fig. 2 is the same; the type of the saw contains the engine 1 and the sawing device 2, which are rigidly connected between each other. When the engine body 1 is powered by a lever 3 that serves to mechanically feed the sawing device 2 when sawing, nail nailing 4 is pivotally attached, which can be rotated in a plane parallel to the plane of the sawing blade of the sawing device 2 both during felling and cutting of trees. The gripper 4 is connected to the engine housing 1 by means of the hinge 5 and the bracket 6 with the refracting mechanism 7. The bracket b is equipped with an abutment 8, and the gripper 4 is equipped with a locking device 9. The engine 1 with the saw unit 2 can be rotated relative to the hinge 5 in two mutually perpendicular planes; To the case of the engine 1 by means of flexible damping elements 10 a handle 11 is attached to the floor with free ends, which is used to carry the saw and pull out the saw unit 2 from the saw the end of the detachable handle 12 with the control lever 13 of the engine 1. The control lever 13 is connected to the throttle valve of the carriage of the engine 1 by means of an elongated cable 14. The work described by a portable chain saw is performed as follows. The saw with the help of the claw grip 4 is mounted on a tree trunk. When the control lever 13 is pressed, the engine 1 is sawn with self-feeding of the saw apparatus 2 into the kerf. This is achieved by using the lever 3 and the cutting resistance of the wood. During sawing, the motorman controls the saw motor at a distance with the aid of a detachable handle 12 with a control lever 13 by means of an elongated cable 14. The distance between the hinge 5 and the tooth line of the saw apparatus 2 is set depending on the power of the saw engine. The design of the described portable motor saw excludes the influence of vibration on the motorist and helps reduce gas pollution in the area where it is located during operation by remote control of the saw motor. Claims of invention A portable motor-saw, including a motor rigidly connected to the sawing apparatus, and a handle with an engine control mechanism, characterized in that, with the aim of Eliminating the influence of vibration on the motorman and reducing gas content in the area where it is located. work, the saw is equipped with a device for rigidly attaching it to a tree trunk, having a nail grip with a hinge and locking device, connected to the lower part of the engine body with a hinged lever and refracting bracket with a stop, allowing the engine to rotate with a saw device in two mutually perpendicular planes, the pita handle is connected to the engine housing by means of flexible damping elements and is equipped with a removable handle with a remote control lever, connected m by means of an elongated cable with a throttle valve of the carburetor engine.
