Background technology
Garbage compression vehicle is mainly used in collecting in time and transportation rubbish.Conventionally, garbage compression vehicle travels, to collect and to transport rubbish.Particularly, the driving engine of garbage compression vehicle detects the rotating speed of driving engine in real time by tachogen, when the difference of rotating speed and staking-out work rotating speed surpasses setting range, by programming controller, control engine rotational speed control apparatus, engine speed is adjusted in setting range, because the power of the compressing mechanism on garbage compression vehicle comes from driving engine, thereby finally realize compressing mechanism and carry out operation with constant speed.
Garbage compression vehicle generally includes four fundamental operatioies, turns over a barrel material loading, presses and fill out circulation, precompressor lifting, shoveling discharging.Referring to Fig. 1 a to Fig. 1 d, shown that the pressure of garbage compression vehicle Zhong Yatian mechanism 4 fills out the process of circulation.Described Ya Tian mechanism 4 comprises slide plate 41 and is arranged on the scraper plate 42 on this slide plate 41, and slide plate 41 is connected with the piston rod of hydraulic actuating cylinder 3, scraper plate 42 is hinged with the piston rod of scraper plate hydraulic actuating cylinder, thus the slip of slide plate 41 and scraper plate 42 open action respectively by flexible realization of piston rod of hydraulic actuating cylinder 3 and scraper plate hydraulic actuating cylinder.At initial position, slide plate 41 is in extreme higher position and scraper plate 42 closures; Start to press and fill out circulation time, scraper plate 42 outwards opens to amplitude peak, to guarantee that rubbish has enough input spaces; Then slide plate 41 moves to extreme lower position by extreme higher position, realizes slide plate 41 descending, to close dog-house, thereby at the inner enclosure space that forms of precompressor; After dog-house is closed, scraper plate 42 is inwardly scraped and is closed, thereby starts compressed garbage, guarantees that rubbish can not leak in precompressor in compression process simultaneously; This tail skid 41 moves to extreme higher position by extreme lower position, realizes slide plate 41 up, and in this up process, the enclosure space consisting of scraper plate 42, slide plate 41, shoveling and precompressor dwindles gradually, finally completes rubbish complete compression process.Conventionally, during waste-skip operation, may carry out a plurality of above-mentioned complete compression processs to identical quantity of refuse, to obtain required rubbish compaction rate, certainly, also can travelling and the different quantity of refuses of collecting repeated to above-mentioned compression process with waste-skip.
In above-mentioned garbage-compressing process, scraper plate 42 is opened and slide plate 41 is descending and while not contacting with rubbish, and the load of whole Ya Tian mechanism 4 is mainly relevant with mechanism self gravitation.At scraper plate 42, inwardly scrape and close and when slide plate 41 is up, scraper plate 42 pressing wastes, make rubbish produce load counter-force to scraper plate 42, now load is born by Ya Tian mechanism 4, scraper plate 42 passes to slide plate 41 by this load counter-force simultaneously, and finally by slide plate 41, this load counter-force is passed on its hydraulic actuating cylinder 3.Be appreciated that above-mentioned load counter-force and quantity of refuse and pressure are filled out the secret room degree of rubbish in process relevant.Particularly, quantity of refuse hour, load counter-force is large; When quantity of refuse is large, load counter-force is large.In addition, at rubbish, press and fill out in process, rubbish is in comparatively loose situation when initial, and now load counter-force is little, and along with the progressively pressure of rubbish is filled out, the degree of firmness of rubbish increase gradually, and correspondingly, load counter-force also will increase thereupon.
