Connection connects on the left of the other end of fine filter 8 and the first quick-release connector 9, and the first quick-release connector 9 is located at oil inlet oil circuit, i.e., with
High-pressure oil pipe connection.Oil return module includes along the sequentially connected radiator 17 of oil return route, return filter 18 and fuel tank 1, oil
Case 1 is also connect with oil return filter 19 and oil ga(u)ge 20 respectively, is connected on the left of the other end of radiator 17 and the second quick-release connector 10,
Second quick-release connector is located at oil return circuit, i.e., connect with oil return pipe.Electromagnetic relief valve 7 is equipped between oil inlet module and oil return module
With pressure transmitter 6.
High-pressure oil pipe pressure releasing method equipped with quick-release connector, comprising steps of
S1. when trash compactor completes compression work, pressure transmitter 6 is by the pressure value real-time transmission in high-pressure oil pipe
To background control system；
S2. background control system makes comparisons received pressure value with pressure preset, when pressure value is more than or equal to pressure
When preset value, the mechanical part of garbage-compressing machine host is restored to original operating states；
S3. background control system issues pressure release signal, and high-pressure oil pipe starts pressure release and timing；
S31. background control system issues pressure release signal, and the first YA2 of reversal valve 12 right obtains electric, while background control system
Start timing；
S32. it is fast followed by the right position YA2 and second of the first reversal valve 12 to be stored in the high pressure oil in host high-pressure oil pipe
Changing-over head 10 flow back into the oil return pipe of hydraulic control system, completes the pressure release to high-pressure oil pipe；
S4. when timing is more than or equal to time preset value, control system shows separable quick-release connector.
Wherein, pressure preset 6MPa, time preset value are 10s, and the mechanical part of host is hopper, Background control system
System is complete machine control PLC.
I.e. when background control system detects that pressure value is more than or equal to 6MPa, it is believed that host compression work is completed, and
Hopper is in extreme higher position, is restored to host original state, and pressure release can be implemented in host high-pressure oil pipe, when venting duration reaches
When 10s, it is believed that pressure release is completed, and the HMI man-machine interface of complete machine control PLC shows mentioning for " can pulling out high-pressure oil pipe quick-release connector "
Show, while hydraulic control system whole power loss stops working, operator can be pulled out after seeing above-mentioned prompt connection host with
The quick-release connector of hydraulic control system.
The host high-pressure oil pipe of existing trash compactor carries out oil return by oil inlet oil circuit, i.e. high pressure oil passes sequentially through oil
Enter host, after the completion of host work, high pressure oil after case 1, oil pump 2, check valve 4, fine filter 8 and the first quick-release connector 9
Oil is returned to after passing sequentially through the first quick-release connector 9, fine filter 8, electromagnetic relief valve 7, radiator 17 and return filter 18 again
Case 1, electromagnetic relief valve 7 are equipped with high pressure spring, keep oil return speed very slow, by adding the first reversal valve 12, change oil return circuit,
Electromagnetic relief valve 7 is avoided, oil return speed can be speeded significantly；And existing trash compactor does not have prompt facility, operator
Member be not aware that when oil return completion, when the separation host and hydraulic control system, easily cause high-pressure oil pipe
There is no pressure release just to separate host and hydraulic control system completely, so as to cause when subsequent operation need in advance to high-pressure oil pipe into
Row draining, causes environmental pollution and the wasting of resources.
Embodiment 2
Embodiment 2 difference from example 1 is that, pressure release circuit further includes the overflow connecting with the first reversal valve 12

Block is used to control the raising and lowering of hopper further.
In normal work, the pressure in host oil pipe is 16MPa, but only needs 6MPa pressure when hopper work, and
Therefore 1% of the working time of hopper less than the complete machine working time only reduces the pressure in oil pipe, both within the hopper working time
The normal operating of complete machine can not be influenced with save the cost.
It when host work completion, is switched by peripheral hardware, control hopper rises or falls:
By lower button SB1,12 left position YA1 of the first reversal valve obtains electric, and high pressure oil successively passes through fuel tank 1, oil pump 2, check valve
4, it is flow back into high-pressure oil pipe after fine filter 8, the first quick-release connector 9,12 left position YA1 of the first reversal valve and overflow valve 11, at this time
Oil pressure is dropped to 6MPa by original 16MPa and is kept constant.
When hopper rises, 15 left position YA3 of the second reversal valve obtains electric, and the high pressure oil of 6MPa is successively through second in high-pressure oil pipe
The right bit stream of 15 left position YA3 of reversal valve, the right position of bidirectional hydraulic lock 14 and Double throttle check valve 13 enter 16 rodless cavity of stirring hydraulic cylinder,
Hopper is controlled to rise.
When hopper decline, the second YA4 of reversal valve 15 right obtains electric, and the high pressure oil of 6MPa is successively through second in high-pressure oil pipe
The left position of 15 right YA4 of reversal valve, 14 left position of bidirectional hydraulic lock and Double throttle check valve 13 flow into 16 rod chamber of stirring hydraulic cylinder,
Control hopper decline.
Obviously, above-described embodiment is only intended to clearly illustrate the technical solution of the utility model example, and simultaneously
Non- is limitations of the embodiments of the present invention.For those of ordinary skill in the art, above explained
On the basis of can also make other variations or changes in different ways.There is no need and unable to give thoroughly all embodiments
It lifts.Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc. should be included in this
Within the protection scope of utility model claims.
