1. the whole sealing performance of the batching tray for the existing dry ice cleaning machine is poor, so that the air pressure in the batching tray is insufficient, and the dry ice spraying efficiency is affected;

as in the prior publication, CN208407925U, a dry ice cleaning machine, discloses a dry ice cleaning machine comprising a dry ice cleaning structure provided on a frame body and a control device for controlling the operation of the dry ice cleaning structure, the dry ice cleaning structure comprising a dry ice cylinder installed on the frame body and an ice crushing mechanism connected with the dry ice cylinder; the ice crushing mechanism comprises an ice crushing tray body with an inner cavity, a cutter disc arranged in the inner cavity of the ice crushing tray body, and an executing element connected with the cutter disc; the end surfaces of the two sides of the cutter head are provided with scrapers. According to the dry ice cleaning machine, automatic dry ice cleaning is realized through the control device, ice cubes on the ice crushing tray body can be divided into particles by adopting the scraper, the ice cube particles adhered to the ice crushing tray body and the wall surface of the cutter disc can be scraped, the situation that gaps between the ice crushing tray body and the cutter disc are adhered with the ice cube particles and the cutter disc cannot enable the cutter disc to run so that the ice crushing tray is blocked by the ice cube particles and the dry ice cleaning machine cannot be used is avoided, the service life of the dry ice cleaning machine is prolonged, in the batching tray disclosed in the document, sealing is realized only through hard matching of bolts between the upper tray and the lower tray, the tightness of the whole batching tray is poor, and the output air pressure is low;

as another prior publication, CN110153105 a-discloses a device comprising a motor, a motor connection pad, a lower cover, an upper air inlet piston press sleeve, a lower ice outlet flange pipe, an upper air inlet flange pipe, a vibrating motor, a vibrating hopper, an adjustable speed floating turntable, a motor shaft sleeve, a motor shaft pin, a pressure regulating valve and a dry ice carrying hole, wherein the adjustable speed floating turntable is suspended and rotated between the lower cover and the upper cover, and a plurality of dry ice carrying holes are formed in the adjustable speed floating turntable; the device enables dry ice to be downwards and uniformly distributed in dry ice carrying holes on the speed-adjustable floating turntable in the vibration hopper, when the speed-adjustable floating turntable rotates to an ice outlet, the dry ice in the carrying holes can be knocked out by high-speed gas, the dry ice can be directly sublimated to become gas at the temperature of between 0.1 and 0.13MPa and between 78.5 ℃, so that the dry ice is quickly gasified in high-speed gas flow when contacting a surface to be cleaned, dirt on the surface to be cleaned is taken away, the optimal cleaning effect can be achieved by adjusting the ice outlet speed, and the batching tray disclosed in the document is provided with a sealing piece, but only the positions of the air inlet and the ice outlet are sealed, and the overall sealing performance is still poor;

2. when the existing dry ice cleaning machine is used for discharging dry ice, the air inlet pipe can blow high-pressure air into the dry ice cleaning machine, the blown high-pressure air is discharged from the ice outlet and also enters the ice inlet, and the air entering the ice inlet can generate certain upward pressure at the lower end of the charging hopper, so that the discharging speed of the charging hopper is lower;

3. because the dry ice can generate lower temperature due to sublimation after entering the batching tray, partial water vapor in the batching tray is sublimated in the ice discharging through groove due to the low temperature, and the dry ice can be adhered in the ice discharging through groove after contacting with the dry ice, so that the problem that the ice discharging through groove is blocked by the dry ice occurs;

4. the air source in the existing dry ice cleaning machine only singly enters the batching tray and carries dry ice to enter a conveying pipe connected with the spray gun from the batching tray, but the air pressure of high-pressure air is gradually reduced in the long-distance conveying process, so that the dry ice is blocked in the conveying pipe;

accordingly, there is a need for improvements in the art that address the above-identified issues.
