The present invention utilizes hydraulic power, through control reversal valve, different valve, realizes that compression cylinder carries out the compressed garbage operation, has the compression time weak point; Compressed capability is strong, the automatic deloading buffering, and high compacted density, cost of transportation is few; The hydraulic pressure temperature rise is little, and is safe and reliable, characteristics such as can control automatically.
Description of drawings
Fig. 1 is a fundamental diagram of the present invention.
The specific embodiment
As shown in Figure 1; A kind of hydraulic means that is used for refuse compaction equipment; Mainly comprise hydraulic pump 1, choke valve 2, reversal valve 3, unloader 4, check valve 5, different valve 6, compression cylinder 7, the omnidistance sensor 8 of displacement of the lines, fuel tank 9, wherein reversal valve 3 is that three position four-way directional control valve, different valve 6 are the two-position three way different valve.Hydraulic pump 1 is connected with the pressure hydraulic fluid port P of reversal valve 3 through choke valve 2; The oil return inlet T of reversal valve 3 is connected with fuel tank 9 through oil pipe; Between hydraulic pump 1 and fuel tank 9, be provided with unloader 4; An actuator port A of reversal valve 3 is connected with the rodless cavity of compression cylinder 7 and the oil-out of check valve 5 respectively through oil pipe, and compression cylinder 7 rod chambers are connected with the actuator port A of different valve 6 through oil pipe, and the oil return inlet T of different valve 6 is connected with another actuator port B of reversal valve 3 through oil pipe; The pressure hydraulic fluid port P of different valve 6 is connected through the oil-in of oil pipe with check valve 5, on the compressing head of compression cylinder, is fixed with the omnidistance sensor 8 of displacement of the lines.
The course of work of the said embodiment of Fig. 1 is:
When static (normality and non-compressed state), the d position (P mouth sealing, A, T mouth are communicated with) of reversal valve 3 metas (P, the sealing of T mouth, A, the sealing of B mouth), different valve 6.The P mouth of reversal valve 3 connects hydraulic pump 1 pressuring oil pipe and takes back oil pipe, T mouth through unloader through choke valve and takes back a chamber and check valve 5 oil-outs that oil pipe, A mouth connect compression cylinder 7, and the B mouth connects the T mouth of different valve 6.The P mouth of different valve 6 connects check valve 5, and the T mouth connects the B mouth of reversal valve 3, and the A mouth connects the b chamber of compression cylinder 7.Compression cylinder does not have pressure oil, and compressing head is stopped at certain position.
During the compressing head compression, put a position (P, A mouth are communicated with, and T, B mouth are communicated with) of reversal valve 3, c position (P, the connection of A mouth of different valve 6; T mouth sealing), pressure oil connects a chamber of compression cylinder 7 through the P of reversal valve 3 mouth, A mouth, drives compression cylinder 7 compressions; The b chamber oil return of compression cylinder 7 connects a chamber of compression cylinder 7 through the A of different valve 6 mouth, P mouth, check valve 5, constitutes differential circuit, increases the pressure oil flow; Shorten compression time, the omnidistance sensor 8 feedback compressing head gait of march of isochrone displacement are when the compressing head gait of march is lower than setting value; The a invariant position of reversal valve 3, the d position of different valve 6 (P mouth sealing, T, A mouth are communicated with); This moment, pressure oil still connect a chamber of compression cylinder 7 through the P of reversal valve 3 mouth, A mouth, drove compression cylinder 7 compressions, and the b chamber oil return of compression cylinder 7 takes back oil pipe through B mouth, the T mouth of the A of different valve 6 mouth, T mouth, reversal valve 3; Increase compression cylinder 7 power outputs, improve compressed capability.
When compressing head is retreated; Put b position (P, the connection of B mouth of reversal valve 3; T, A mouth are communicated with), the d position of different valve 6 (sealing of P mouth, T, A mouth are communicated with); Pressure oil is retreated through the T mouth of the P of reversal valve 3 mouth, B mouth, different valve 6, the b chamber drive compression cylinder 7 that the A mouth connects compression cylinder 7, and a chamber oil return of compression cylinder 7 is through taking back oil pipe through the A of reversal valve 3 mouth, T mouth.
During compression cylinder 7 compression, when compressing head speed is lower than setting value, the omnidistance sensor 8 of displacement of the lines sends signal, switches the d position of different valve 6; Increase the power output of compression cylinder 7, the omnidistance sensor 8 of displacement of the lines sends signal, reversal valve 3 metas, unloader 4 off-loads after the compressing head compacting; Energy discharges, a position of reversal valve 3 once more, pressurize a period of time; Improve compacted density, reversal valve 3 metas, unloader 4 off-loads then, system sends the b position of signal reversal valve 3; Return to initial point behind the compression cylinder 7, one stroke is accomplished in unloader 4 off-loads.
