Title:
ROAD SURFACE CLEANING CAR
Document Type and Number:
Japanese Patent JP3189938
Kind Code:
B2
Abstract:
PURPOSE: To make it possible to collect surely refuse irrespective of size and weight and prevent the generation of troubles that a flap may catch a main brush in an over throw type road surface cleaning car.
CONSTITUTION: Light weight refuse and large refuse, such as empty cans push up easily a flexible second flap and pass by and arrive at a first flap 20. Small refuse passes by a clearance S while refuse larger than the clearances S will pass by, deflecting the first flap 20 backwards. The first flap 20 whose mounting position is located at a higher position than a prior art position, is shorter in length compared with the mounting area by the clearance S, which prevents the first flap from catching the main brush 12 even when it is bent backwards. The second flap 26 returns to a grounding state after the passage of the refuse while the main brush 10 is enveloped with a rear flap 30 and the second flap 26, which makes it possible to prevent dust and dirt from coming out during sweeping time and the suction air current from being leaked.
