Dynamic intelligent control system and method for pusher head of conjoined compression box

Abstract

The invention relates to a dynamic intelligent control system and method for a push head for an integrated compression box. The control system comprises a controller, a starting switch, a pressure transmitter, an unloading valve, a forward push valve, a return valve and a contactor; the starting switch is connected to one input end of the controller; the pressure transmitter is connected to the contactor, and the contactor is connected to one input end of the controller; the unloading valve, the forward push valve, the return valve and the contactor are connected to the output end of the controller; and an oil pump motor is connected to the controller and is controlled to work through the controller. The control method comprises the following steps of S1, starting the system; S2, enablinga push shovel to advance; S3, making a comparative judgment; S4, judging the pressure; S5, starting the return valve; S6, judging whether return is in place; and S7, stopping working. The control method has the advantages that the oil temperature of a hydraulic system of equipment can be decreased by about 5 DEG C, the equipment operation efficiency can be improved by 5% or above, in addition, thefailure rate of the equipment is decreased, and the noise is reduced by 5%.

Description

technical field [0001] The invention discloses a control method for a conjoined compression box, in particular a dynamic intelligent control system and method for a push head of a conjoined compression box, belonging to the technical field of domestic waste treatment equipment. Background technique [0002] One-piece compression box is a kind of garbage compression equipment. Its main function is to compress domestic garbage into a closed box, and then transfer and unload the full box by a special vehicle. [0003] At present, the one-piece compression box in the prior art mainly relies on the push head driven by the hydraulic system cylinder to automatically cycle back and forth to complete garbage compression. Therefore, during the working process of the one-piece compression box, the automatic reversing control of the push head becomes this The key to class device control. In order to realize the automatic reversing of the garbage pusher in the conjoined box, the traditi...

Problems solved by technology

[0004] Conventional push head reversing mode is a static working mode, the two kinds of static pressure detection reversing or delay reversing can not reflect the motion state of the push head, the disadvantage of the former method (pressure detection reversing) is that it cannot guarantee the garbage The loading density and loading capacity, if there is a jam, etc., it will still be judged to have been compressed, and then change direction; and the latter method (delayed changeover) needs to stand still and hold the pressure for a period of time each time when the pusher changes direction , the process of short-term pressure holding is actually a process of doing useless work, which consumes more electric energy and reduces loading efficiency. At the same time, it will increase the impact and wear of the mechanical structure, increase the temperature rise of the hydraulic oil, and burst the hydraulic pipeline.
