[0031] The working process of the utility model:

[0032] The electric components in the utility model are all triggered to run by PCL controller;

[0033] The garbage is collected by the horn-shaped rainwater collecting port 7 into the rainwater and sewage filtering part 31, and is filtered layer by layer inside the rainwater and sewage filtering part 31. The filtered garbage is collected into the fan-shaped rainwater collecting part 51 inside the rainwater and sewage collecting cavity 5, and the screened garbage is collected into the fan-shaped garbage storage cavity 4 provided with the garbage dewatering device 41. The sewage dewatered by the garbage dewatering device 41 is collected into the fan-shaped sewage collecting part 52 inside the rainwater and sewage collecting cavity 5 and is discharged through the sewage drainage pipe 521, and the garbage is discharged through the solid garbage discharge pipe 451 to the solid garbage collecting device 8 for centralized treatment.

[0034] The garbage is collected by the horn-shaped rainwater collecting port 7 into the rainwater and sewage filtering part 31, and is filtered layer by layer inside the rainwater and sewage filtering part 31. The filtered garbage is collected into the fan-shaped rainwater collecting part 51 inside the rainwater and sewage collecting cavity 5, and the screened garbage is collected into the fan-shaped garbage storage cavity 4 provided with the garbage dewatering device 41. The sewage dewatered by the garbage dewatering device 41 is collected into the fan-shaped sewage collecting part 52 inside the rainwater and sewage collecting cavity 5 and is discharged through the sewage drainage pipe 521, and the garbage is discharged through the solid garbage discharge pipe 451 to the solid garbage collecting device 8 for centralized treatment.

[0035] The first filter grid 311, the second filter grid 312 and the third filter grid 313 are gradually reduced in size from top to bottom. When the volume of the garbage to be filtered is greater than the size of the filter grid hole, the rotating hole-type push rod 32 rotates and pushes the garbage into the garbage dewatering device 41 in the fan-shaped garbage storage cavity 4. The size of the holes on the surfaces of the first push rod 321 and the second push rod 322 of the rotating hole-type push rod 32 is consistent with the size of the holes provided on the surfaces of the second filter grid 312 and the third filter grid 313. The holes provided on the rotating hole-type push rod 32 further filter the water remaining between the garbage when rotating and pushing the garbage, thereby reducing the amount of leachate.

[0036] After the garbage is collected by the first filter grid 311 at the top of the rainwater and sewage filtering part 31, the garbage falls to the second filter grid 312 for simple filtering. When the volume of the garbage is greater than the size of the second filter grid 312 hole, the garbage is discharged into the garbage dewatering device 41 through the first push rod 321.

[0037] The water storage barrel 42 inside the garbage dewatering device 41 is the outer wall contour completely containing the dewatering barrel 43. When the motor 44 drives the dewatering barrel 43 to rotate and separate, the garbage in the dewatering barrel 43 will be separated from the leachate by centrifugal force into the water storage barrel 42. The leachate in the water storage barrel 42 is discharged into the fan-shaped sewage collecting part 52 inside the rain and sewage collecting cavity 5 through the drain pipe 421, and is stirred in the fan-shaped sewage collecting part 52 by the stirrer 522. The residual small garbage is discharged through the sewage drain pipe 521. The garbage in the dewatering barrel 43 will be discharged through the blocking plate 452 hinged to the bottom gap of the dewatering barrel 43 and completely coinciding with the gap. When the motor 44 stops working, the electromagnetic block 454 is energized to generate a repulsive force between the electromagnetic block 454 and the magnetic block 453, so as to open the blocking plate 452.
