The application discloses a collapsible water glass sand proportioning optimization device and method, and relates to the field of sand proportioning optimization devices.The device comprises: a stirring tank for stirring mixed materials; a spiral feeder comprising two and respectively used for adding old sand and new sand to the stirring tank; a reagent adding tank for storing reagents, which comprises two and stores the same reagents; a reagent adding device comprising two sets of piston type feeding devices and a driving device for driving the movement of the piston rods of the piston type feeding devices, the two sets of piston type feeding devices are respectively communicated with the two reagent adding tanks and are both communicated with the stirring tank, and the driving device asynchronously drives the two sets of piston type feeding devices so that when the driving device is turned on, one set of piston type feeding device always adds reagents to the stirring tank and the other set of piston type feeding device extracts reagents. The application firstly realizes uninterrupted feeding through the two sets of piston type feeding devices driven asynchronously; in addition, the rotation of the output shaft is bidirectionally controlled through the planet gear structure driven bidirectionally, which not only can amplify the number of rotation circles, but also can more finely control the feeding speed, which is beneficial to improve the accurate control of reagent adding; finally, the eccentric hinge position of the connecting rod is adjusted through the piston type sliding adjustment structure arranged on the eccentric disc to adjust the limit value of the adding amount, and the double adjustment mechanism is formed in cooperation with the rotation speed, which provides favorable conditions for adjusting the proportion in the proportioning process.

The utility model discloses a kind of glue dispensing devices, including placing barrel, glue barrel is placed in placing barrel, placing barrel includes the glue outlet for the glue in glue barrel to flow out.Squeezing mechanism, squeezing mechanism is set in the end of glue barrel away from glue outlet, and squeezing mechanism is used to squeeze the glue in glue barrel towards glue outlet.Fixed block, fixed block is fixedly connected with placing barrel, first passage that fixed block is opened with glue outlet is communicated, and the connecting place of fixed block and placing barrel is provided with switch valve that opens and closes first passage.Gear pump mechanism, gear pump mechanism includes the first shell that is fixedly connected with fixed block, second passage and third passage are opened on the first shell, first passage is communicated with second passage, sensor for collecting the pressure of glue in second passage is also fixed on the first shell, glue dispensing head is fixed in third passage and communicated with third passage.Glue supply amount when glue dispensing device gluing is accurate, and glue deficiency can be found in time, avoid glue dispensing head gluing without glue or insufficient.

The invention belongs to the technical field of cleaning equipment, and particularly relates to an unmanned cleaning equipment drive-by-wire chassis which comprises a chassis body and a wheel assembly installed at the bottom of the chassis body, and further comprises a driving assembly installed in the chassis body and used for driving the wheel assembly to work; the EPS steer-by-wire assembly is installed in the side, close to a vehicle head, of the chassis body and used for driving the wheel assembly to steer. According to the invention, unmanned cleaning full-process electric control cooperative linkage can be realized, the running track of equipment is accurately controlled, the operation accuracy is improved, garbage and dust integrated cleaning is completed, the cleaning efficiency and the cleaning effect are greatly improved, steering, driving and braking quick response is realized, the unmanned operation safety is improved by means of braking redundancy design, and the working efficiency is improved. All the assemblies are modularly integrated and reasonable in layout, and are adaptive to various unmanned cleaning operation scenes.
