Description

Technical Field

[0001] The invention discloses a double-chamber garbage bin for a road sweeper and a working method of the garbage bin, belonging to the technical field of sanitation vehicles. Background Art

[0002] With the increasing mileage of highways and urban roads, the task of cleaning and maintenance is becoming increasingly arduous. The working speed and cleaning capacity of existing road sweepers are gradually unable to meet the daily maintenance needs of highways. The existing high-speed road sweepers on the market are mainly divided into two categories: suction pick-up type and roller sweeping type. The suction pick-up type uses a fan to suck the inside of the garbage bin to form a negative pressure area, sucking small particles, dust and small lightweight flake garbage on the road surface into the garbage bin, sedimentation and filtration, so as to achieve the purpose of cleaning. This method cannot clean large pieces, long strips, and heavy garbage; while the roller sweeping type first uses a sweeping disc to gather the garbage directly under the vehicle, and then uses a sweeping roller to sweep the garbage into the lifting scraper, and the scraper brings it into the garbage bin. This method can effectively clean large garbage, but the cleaning effect is poor for small garbage such as small particles and dust. Therefore, this application proposes a double-chamber garbage bin and a garbage bin working method for a road sweeper to meet the garbage collection and transportation needs of "A Double Cleaning Fast Road Sweeper" (Application No.: CN202410497310.2).

[0054] During specific operation, under normal working conditions, cylinder three 09 extends out, damper three 081 is in an open state, cylinder one 05 and cylinder two 07 are in a retracted state at the same time, the upper surfaces of damper one 04 and damper two 06 are tightly fitted with the lower surface of the middle partition 0125, and the fan is started. A negative pressure is formed inside the garbage box 01 under the action of the fan, and the garbage and sewage mixture enters the suction and collection area B under the push of the negative pressure airflow, wherein the garbage and sewage are physically settled, and the dirty air enters the filter bag installation area C upward, and under the action of the filter bag 03, the clean air enters the negative pressure area D, and the dust particles are blocked and left on the filter bag 03 or fall into the suction and collection area B. The clean air in the negative pressure area D continues to flow forward into the air cavity one and the air cavity two under the suction force of the fan, and then enters the fan through the air outlet three K and the air outlet four L, and then enters the upper wind hood 08 upward from the fan outlet through the air outlet five M, and is finally discharged into the atmosphere backward.

[0055] The filter bag needs to be self-cleaned later. The first step is to clean the right filter bag 03. The cylinder 3 09 is retracted, the damper 3 081 is in a closed state, the cylinder 1 05 is retracted, the upper surface of the damper 1 04 is closely fitted with the lower surface of the middle partition 0125, the cylinder 2 07 is extended, the lower surface of the damper 2 06 is closely fitted with the upper surface of the lower panel 0123, the suction pipe 015 is closed, and the fan is started. Under the action of the fan, the airflow of the garbage box 01 forms an internal circulation;

[0056] Specifically, the air in the filter bag installation area C enters the left side of the negative pressure area D through the left filter bag 03. The air in the left side of the negative pressure area D continues to move forward through the air cavity 1 and the air outlet 3K under the suction of the fan, and then enters the fan through the air outlet 5M, the air cavity 3, the upper wind cover 08, the air outlet 7P, and the air cavity 2 from the fan outlet to the right side of the negative pressure area D. The air on the right side of the negative pressure area D enters the filter bag installation area D through the right filter bag 03 under the action of the fan outlet pressure, and blows off the dust attached to the surface of the right filter bag 03. The air flow circulates along this air duct until the right filter bag 03 is cleaned.

[0057] Step 2: Clean the left filter bag 03, shrink the cylinder 3 09, close the damper 3 081, extend the cylinder 1 05, and tightly fit the lower surface of the damper 1 04 with the upper surface of the lower panel 0123. Extend the cylinder 2 07, and tightly fit the upper surface of the damper 2 06 with the lower surface of the middle partition 0125. Close the air suction pipe 015, and start the fan. Under the action of the fan, the airflow of the garbage bin 01 forms an internal circulation.

[0058] Specifically: the air in the filter bag installation area C enters the right side of the negative pressure area D through the right filter bag 03. The air in the right side of the negative pressure area D continues to move forward under the action of the fan suction force through the air cavity 2 and the air outlet 4 L, and then enters the fan from the fan outlet through the air outlet 5 M, the air cavity, the upper wind cover 08, the air outlet 6 N, and the air cavity 1, and enters the left side of the negative pressure area D. The air on the left side of the negative pressure area D enters the filter bag installation area D through the left filter bag 03 under the action of the fan outlet pressure, and blows off the dust attached to the surface of the left filter bag 03. The air flow circulates along this air duct until the left filter bag 03 is cleaned.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
