Abstract
The utility model relates to a low-vibration portable cutting/irrigating machine, which belongs to the portable agriculture and forest machinery. The utility model relates to an improving product which is designed aiming at a portable cutting/irrigating machine with the gasoline engine displacement of 30CC-50CC and with large hand vibration. The utility model is characterized in that an operation rod which is transmitted by a flexible shaft is a flexible sleeve pipe with multi-point full-floating vibration-damping structure; a control rod is the built-in non-precompression elastic vibration-damping structure; when matched with a 1 E 40 F petrol engine, two automatic centrifugal flying blocks are connected to a lug boss at the end surface of a vane of the petrol engine by pin shafts. The utility model has obvious effect on reducing the hand vibration of the cutting/irrigating machine.
Description
The utility model belongs to portable agriculture and forestry machinery.
Portable brush saw is widely used in lawn care, tending [after young plantation, and the tea place is upgraded, and the herbage harvesting waits an operation.Portable brush saw all has an elongated working beam and power transmission shaft, because the vibration that working beam and the inevitable straightness error of power transmission shaft axle center line are produced is one of main vibration source of brush saw, surveys its handgrip vibration values and reach 12m/s when declared working condition
2～17m/s
2The long-term use, operator is easily violated the occupational disease of a kind of crying " empty-handed disease ".Therefore, reducing the feel vibration is common concern of portable brush saw designer and operator and urgent problem.
The purpose of this utility model is that a kind of improved brush saw will be provided, and it can prevent effectively because of the too big injury that brings to operator of feel vibration.
Main points of the present utility model are by improvement design, the multistage full floating vibration attenuation mechanism of application to portable brush saw working beam, control stick structure, reduce the feel vibration values significantly, make it reach 6m/s
2～10m/s

Fig. 1 is the utility model structural representation.
Fig. 2 is it (1) cutaway view of the utility model.
Fig. 3 is it (2) cutaway view of the utility model.
Centrifugal fly piece drive mechanism schematic diagram when Fig. 4 is it (3) supporting 1E40F type gasoline engine of the utility model.
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, the utility model is by working beam (1), control stick (2), and gasoline engine (3) is formed, and supporting gasoline engine is the high speed two-stroke gasoline engine, and discharge capacity is 30CC～50CC.Working beam is shown in figure (2), the diameter of driving snake (4) is φ 7mm～φ 10mm, be installed in the flexible sleeve (5) of modified engineered plastic making, flexible sleeve (5) is installed in the aluminum pipe (7) by a plurality of elastic bearing seats (6) supporting, forms multiple spot full floating vibration-proof structure.Control stick as shown in Figure 3, handle (9) by the fastening connection of fixed cap (12) after, be installed in the handle set (10) in the no precompressed elastomer (11), vibration damping gum cover (8) is installed on the handle (9), for the operator gripping.
When the supporting gasoline engine of the utility model is the 1E40F type, its output end structure as shown in Figure 4, two automatic centrifugals fly piece (16) and are installed on the boss of blade (13) end face by pin axle (14), fly determining in conjunction with the pulling force of rotating speed by weight that flies piece and spring (15) of piece.
The multistage multiple spot full floating vibration reducing measure that the utility model is taked has reduced portable brush saw feel vibration values significantly.
