Abstract
The utility model is taking forest zone shrub, draft as application, for the inefficient situation of fire prevention brush, specialized designs a kind of novel hydraulic cantilevered fire prevention brush saw, this fire prevention brush saw adopts tractor to hang traction, and brush amplitude and cutter angle can be adjusted on request, thereby meet the fire prevention brush requirement of different range, package unit adopts full hydraulic drive, can conveniently realize fire prevention brush operation, have efficient, laborsaving, the feature of flexible operation.
Description
Technical field
The utility model relates to a kind of brush equipment, is specifically related to the arm-type fire prevention brush of a kind of hydraulic suspension equipment.
Background technology
Shrub and draft are surface fuel chief components, are important combustibles alive in standing forest.Brush not only can reduce the combustible load alive on earth's surface, can also reduce the continuity of combustible substance distribution, destroy its because of self horizontal distribution continuity of forming of growth and and Qiao fill with the vertical distribution continuity (spreading to the differentiation of crown fire to prevent and to control surface fire) between grass, the level can effectively avoid like this forest fires generation time spreads and vertical extension.Domestic fire prevention brush generally adopts portable brush saw (side hanging and backpack) the brush operation of preventing fires, the problem such as this mode exists manpower consumption large, and labour intensity is large, and efficiency is low.In order to improve fire prevention brush efficiency, reduce human cost, reduce labour intensity, research and development high-efficiency fireproof brush equipment just seems particularly important.
Summary of the invention
The technical problem solving: the deficiencies such as efficiency is low in order to overcome in tradition fire prevention brush work, labour intensity large, operating area limitation, solve cutting speed, cutting angle and cutting-height in cutting process and change the problem bothering, the utility model has designed the arm-type fire prevention brush saw of a kind of hydraulic suspension, this brush saw is taked to articulate with tractor, full hydraulic drive, can realize the brush operation of different amplitudes by hydraulic arm, brush speed also can regulate, the automaticity of fire prevention operation is improved, and is all protected in operating efficiency and operating area.
The utility model solves the technical scheme that its technical problem adopts: this machine is connected with tractor by suspension arrangement, provide power drive hydraulic pump to realize the work of hydraulic system by tractor motive power output shaft, realize the cutting movement of reciprocating cutterbar by fluid motor-driven toggle, by throttle valve adjustment cutting speed, realize the adjustment of cutting orientation and cutting angle by Driven by Hydraulic Cylinder cantilever, realize the target of high efficiency cleaning combustible carrying capacity.The arm-type fire prevention brush saw of hydraulic suspension is adjusted hydraulic cylinder, reciprocating cutterbar and hydraulic system by connection frame, principal arm, auxiliary, principal arm hydraulic cylinder, auxiliary hydraulic cylinder, cutter and is formed, by controlling operation height and the job area of flexible adjustment brush saw of boom cylinder, by controlling the operating angle of flexible adjustment cutter of cutter hydraulic cylinder.Reciprocating cutterbar is made up of moving knife, connection seat, connecting rod, hydraulic motor, bent axle and stationary knife, and the rotation of hydraulic motor changes into the linear reciprocating motion of moving knife, regulator solution pressure motor flow can change reciprocating cutting speed.On connection frame, be designed with connecting lug for articulating with tractor three point linkage and for being connected the connecting lug of main boom and main boom hydraulic cylinder, step-up gear, hydraulic pump, hydraulic oil container are installed on connection frame.
The beneficial effects of the utility model are: this fire prevention brush saw adopts all-hydraulic control, and operating efficiency is high, and operation intensity is little.Can adapt to the adjustment of operation amplitude and angle in certain limit by the adjustment of hydraulic arm, meet the requirement of forest zone complex job.Can easily realize cutting speed according to job requirements, cutting-height, can be in relatively severe landform work, and working environment adaptability is good.
