Description
Technical field
The invention belongs to digging spade chisel and destroy firm field, specifically a kind of gasoline engine breakup pick.
Background technology
Gasoline engine breakup pick is a kind of safe, light, practical excavation, breaking tool.It, need not rely on the advantage that the auxiliary equipment such as power supply, large-scale air compressor machine, electromotor just can use whenever and wherever possible, is subject to the consistent favorable comment of users at home and abroad.Building engineering construction is can be used for by changing different facility, the broken engineering of constructing road, the firm field of multiple digging spade chisel destruction such as the demolition reduction in electric power, telecommunications, fire-fighting relief, cable pre-buried, the maintenance of trench digging, HIGHWAY MAINTENANCE, civil engineering, mining work, severe cold region icebreaking shovels are frozen, the dredging of stacked frozen road.
At present, the structure of gasoline engine breakup pick is all " P " word form Design, adopts the put-put of ordinary construction to be suspended on the side of breakup pick main body, and this design makes the center of gravity deflection electromotor of complete machine.Additionally provisioned put-put has presenting of the factors such as engine radiating function is poor, carburetor temperature is too high, air filter has gasoline back attack phenomenon, impulsive force unstable.Its feature is mainly the central point of the weight deviation pick rod of electromotor, this design makes center of gravity deflection electromotor one side of complete machine, owing to gasoline engine breakup pick is altofrequency impact endurance test shock feature, 2 drawbacks can be caused after the machine gravity deflection presented, the drawbacks such as engine aluminum limit lid easily ftractures, broken impulsive force is impaired, suffer from invisible impact to operator and crushing efficiency.
The structure of existing gas handling system and gas extraction system all designs 2 sides at engine cylinder, so that the lateral dimension of electromotor is excessive, product design has circumscribed defect；
Some electromotors in the market due to acoustic filter from engine cylinder too close to, exhaust silencer system is as the process device of toxic emission and buffering sound wave, but this part of exhaustor is left in the basket in major part machine, it is not taken as a complete partial design of independent exhaust pipe, but directly acoustic filter is connected on engine cylinder, cause that the heat radiation of engine cylinder and acoustic filter is not smooth.And all can there is the phenomenon of scuffing of cylinder bore in piston in power, piston ring, cylinder after the heat produced during engine cylinder running rises because of the not smooth heat that dispels the heat, accelerating the abrasion of other parts of electromotor, this reaction causes that the oil consumption of electromotor, power, rotating speed all can receive impact in various degree；
Intake manifold length size is too short, carburetor from engine cylinder too close to, the heat produced during engine cylinder running makes the temperature of gasoline mixture produce change, causing gasoline temperature too high and create boiling range, this reaction makes the oil consumption of electromotor, power, rotating speed all can receive impact in various degree；
Owing to air inlet pipe is too short, carburetor from engine cylinder distance too close to, cause filtering cotton when gasoline mixture recoils time, it is impossible to effectively to play mitigation, make filtering cotton produce the phenomenon of adsorbed gasoline, make the unstable factor such as disabler of carburetor and air filter；
Existing air inlet, gas extraction system structure only one of which connect fixing point design, the vibrations produced during engine operation cause the loosening of parts of air intake system, ftracture, the bad phenomenon such as come off；
The material and technology of the current blow cylinder in gasoline engine breakup pick has many deficiencies often to annoying manufacturing industry.Defect substantially following some, 1, the material batch of steel material is difficult to uniformity, 2, heat treatment is controlled and is difficult to reach requirement, 3, the endoporus of blow cylinder makes deep hole tribulation reach the cylindricity in hole excessively deeply, perpendicularity and roughness, cause impact piston, jump bit, impact the sealing member Fast Wearing on son and sealing property reduces, 4, owing to blow cylinder adopts steel construction, in order to reach roughness and the cylinder body hardness of grinding process, cause that shock resistance vibration resistance reduction cylinder body easily ftractures after losing toughness by making blow cylinder body reach certain hardness after heat treatment, 5, owing to blow cylinder adopts steel construction at impact piston, jump bit, in blow cylinder, reciprocal movement friction easily generates heat and cuts the steel construction heat radiation defect such as slow.Thus affect impulsive force, service life is greatly reduced.
The impact crank of current gasoline engine breakup pick is all single head crank, impacts the mechanism that crank is a kind of passive transmission energy, owing to single head crank impacts crank only one of which strong point bearing load drivening rod rotary reciprocating motion when rotary reciprocating motion.Owing to when crank operates, stress point concentrates on and is easily caused bearing damage on a point, cause that rotating energy can not give full play to torsion and be consumed, piston scraping is ordered about in the connecting rod axial thrust effect of waving simultaneously, the sealing member Fast Wearing and the sealing property that cause impact piston reduce, the defects such as impulsive force is impaired.Developing by engine crankshaft owing to single head impacts crank, being provided with T-shaped structure weight block purpose is reduce vibrations.Mistaken ideas are in that a kind of is by the mechanism of active transmission energy, and impact the mechanism that crank is a kind of passive transmission energy, impact 360 degree of reciprocating rotary drivening rods of crank to impact piston reciprocal vertical movement in blow cylinder and make the air pressure in air chamber produce change.Exactly T-shaped structure weight block reduce vibrations but significantly consume by drive transmission energy, otherwise gasoline engine breakup pick, electronic breakup pick, impact bore class itself needs be exactly vertical vibration and play fragmentation.
