[0025] Working principle:

[0026] The equipment is placed at the garbage collection and compression station; first, the power connection socket on the equipment is connected to the power supply at the station and powered on; the equipment is started to energize the entire control circuit; the motor is started and the oil pump is unloaded first.

[0027] First, the control system can realize independent action;

[0028] The compression cylinder 13 extends: the electromagnet in the reversing valve 1 6, the electromagnet in the reversing valve 2 7, and the right electromagnet in the reversing valve 4 9 are energized, and the oil pump 1 1 and the oil pump 2 2 supply oil at the same time, so as to achieve rapid extension and compression operation;

[0029] The compression cylinder 13 differential extension action: the electromagnet in the reversing valve 1 6, the electromagnet in the reversing valve 2 7, the right electromagnet in the reversing valve 4 9, and the electromagnet in the reversing valve 5 11 are energized, and the oil pump 1 1 and the oil pump 2 2 supply oil at the same time, realizing rapid differential extension to realize compression extension;

[0030] The compression cylinder 13 retracts: the electromagnet in the reversing valve 1 6, the electromagnet in the reversing valve 2 7, and the left electromagnet in the reversing valve 4 9 are energized, and the oil pump 1 1 and the oil pump 2 2 supply oil at the same time, realizing rapid retraction and return operation;

[0031] The feeding cylinder 12 extends: the left electromagnet in the reversing valve 3 8 is energized, so that the cylinder extends to perform the lifting and flipping operation of the feeding mechanism;

[0032] The feeding cylinder 12 retracts: the right electromagnet in the reversing valve 3 8 is energized, so that the cylinder retracts to perform the lowering and flipping operation of the feeding mechanism;

[0033] During the compression cycle, when the pressure of oil pump 1 is less than 9MPa, pressure transmitter 16 does not provide a signal, and the compression cylinder 13 is rapidly extended by combining oil pump 1 and oil pump 2; when the pressure of oil pump 1 is greater than or equal to 9MPa, pressure transmitter 16 provides a signal, oil pump 1 is immediately unloaded, reversing valve 5 11 loses power, and oil pump 2 supplies oil alone;

[0034] When the oil pump 2 pressure reaches 19MPa, the pressure transmitter 2 17 takes the pressure signal and sends a signal after a delay of 1s, so that all the reversing valves are in the power-off state for 1s before the compression cylinder 13 retracts; when the pressure transmitter 16 detects a pressure greater than 19MPa, it is retracted into place;

[0035] Feeding cycle action: when the feeding mechanism rises, the compression cylinder 13 retracts (after the feeding rise is completed, the compression cylinder 13 continues to retract into place); when the feeding mechanism descends, the compression cylinder 13 performs the current action and is not affected;

[0036] When the feeding mechanism is operated to rise or fall, a compression cycle is performed after completion. The number of compression cycles can be set, generally 3-4 times is appropriate;

[0037] Equipment full alarm: Use time plus pressure (7s, 14MPa), that is, after the compression cylinder 13 reaches 14MPa, the compression cylinder 13 extends into place for more than 7s. If this happens twice in a row, the equipment full alarm will be prompted.

[0038] The feeding cylinder 12 is retracted to perform the descending action, the left electromagnet of the reversing valve 49 is energized, and the feeding mechanism descends to the garbage loading state.

[0039] After the garbage is loaded, the feeding cylinder 12 is extended to perform the upward flipping action, the right electromagnet of the reversing valve 49 is energized, and the feeding mechanism flips up to the position; during the upward flipping process of the feeding mechanism, the compression cylinder 13 always performs the retraction action, and after retracting to the position, when the feeding cylinder 12 has not yet been extended to the position, the compression cylinder 13 suspends the action.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
