Cleaning machine
First Claim
1. A cleaning machine comprising:
- a frame;
a suction blower mounted on the frame and having an inlet and an outlet, for generating an air flow for entraining dirt in an air stream, and for drawing the air-entrained dirt into the cleaning machine;
an intake opening communicating with the inlet of the suction blower for receiving the air stream and entrained dirt, including relatively large dirt and relatively small dirt such as dust;
a main separator for receiving the air stream and entrained dirt from the suction blower outlet, and for separating the relatively large dirt from the air stream and for discharging the air stream and entrained dust;
a subseparator for receiving the air stream and entrained dust discharged from the main separator, and for separating the dust from the air stream;
a dirt receptacle made of an air-impermeable material detachably attached under the main separator for receiving the dirt separated from the air stream, the dirt receptacle having an upper edge defining an opening, the upper edge having a catch portion;
a pivoting rod having top and bottom ends, the pivoting rod being pivotally mounted at its bottom end to the frame, and being engageable at its top end with the catch portion of the receptacle;
a clamp for detachably securing the dirt receptacle by its upper edge to the main separator, the clamp located at a position opposite the dirt receptacle catch portion, whereby the dirt receptacle is detachably secured to the main separator; and
the pivoting rod, while being engaged at its top end with the receptacle upper edge catch portion, being pivotable between a first position in which the pivoting rod supports the dirt receptacle under the main separator and a second position in which the receptacle is removed from the main separator to land on the ground at a point which is laterally displaced from the first receptacle position.

Abstract
A cleaning machine includes a frame having wheels, a suction blower having an inlet and an outlet mounted on the frame, an intake opening communicated with the inlet of the suction blower for sucking dirt containing relatively large dirt such as fallen leaves and relatively small dirt such as dust together with air, a main separator for separating the relatively large dirt, a subseparator for separating the relatively small dirt from the air having passed through the main separator, and a dirt receptacle made of an air-impermable material detachably attached under the main separator through a pivoting rod which is pivotably mounted to the frame so as to support the receptacle to the main separator and a clamp member for securing the dirt receptacle to the main separator.
