[0005] A steel gate;

[0006] A sieve plate, the sieve plate and the bottom of the steel gate are fixed to the bottom plate; the sieve plate and the steel gate are arranged opposite to each other; a through groove is formed in the lower part of the sieve plate;

[0007] A self-sealing unit, the self-sealing unit comprises slides fixed to both sides of the lower part of the sieve plate; a filter plate is slidably arranged inside the slides, a limiting block is fixed to the upper part inside the slides; force plates are integrally formed at the top and bottom of the filter plate respectively, a limiting groove is integrally formed at the bottom force plate; a through groove is formed in the top force plate opposite to the limiting groove; I-shaped wheels are rotatably arranged on both sides of the upper part of the sieve plate, a steel wire body is sleeved on the I-shaped wheels, one end of the steel wire body is fixed to the top of the filter plate, and a counterweight column is fixed to the other end; a sliding sleeve is slidably arranged on the counterweight column, and the sliding sleeve is fixed to the sieve plate;

[0008] A filtering and collecting unit, the filtering and collecting unit comprises a cover plate fixed above the slides, guide rails are integrally formed on the mutually approaching surfaces of the cover plate, a sliding plate is slidably arranged inside the guide rails, a filter basket is fixed to the sliding plate, and the side of the filter basket close to the sieve plate is hollow;

[0009] A support arm is fixed on the gate panel of the steel gate, and the support arm is movably pressed against the limit groove.

[0010] When the filter basket collects dirt, due to the gravity of the filter basket, it can be pressed against the force-bearing plate at the top of the filter plate, thereby pressing down the force-bearing plate. When pressing down, the steel wire body is pulled, and the steel wire body pulls up the counterweight column through the I-shaped wheel until the filter plate disengages from the through groove; at this time, the filter basket is facing the through groove; when the dirt collection is completed, the steel gate continues to move upward, pushing up the filter basket, and the filter basket disengages from the force-bearing plate at the top of the filter plate.

At this time, the flap is turned outwards under its own gravity, so that the discharge port can discharge smoothly, and the dirt in the filter basket is scraped to the guide hopper by the scraping arm unit. The dirt is sent into the garbage collection well through the guide hopper. After the dirt is discharged, the support arm moves downward, and the filter basket is under the action of its own gravity. The filter basket can move downward along the guide rail again. When the filter basket moves downward, the flap is pressed against the discharge port by the guide rail, realizing the closure of the end of the filter basket.
