Movable dust collection device

A dust collection device comprising:

• a processing table (10) including two side walls (11), and a plurality of transverse plates (12) connected between the two side walls (11), the two side walls (11) being installed on an installation floor (50);
• an air duct (20) provided in the processing table (10) and located close to one of the side walls (11), a blower (60) connected to one end of the air duct (20);
• a processing machine (30) including a processing gun (31) extending downward from one side of the processing machine (30), and two foot bases (32) crossing outside of the processing table (10), the processing machine (30) movable along a length direction of the processing table (10) with the two foot bases (32), and
• a collection unit (40) located in the processing table (10) and including a suction box (41), a drive unit (42), and a control unit (43), the suction box (41) communicating with the air duct (20) and having two dust boxes (411) and an air path (412), the air path (412) located between the two dust boxes (411), and each dust box (411) including a plurality of suction holes (4111) that are in communication with the air path (412), the driving unit (42) including a motor (422), and a plurality of driving wheels (421) arranged on a bottom of the suction box (41), the control unit (43) including a controller (432), a transmitter (433), and a plurality of receivers (434) that are electrically connected to each other, the controller (432) electrically connected to the motor (422), the transmitter (433) transmitting wireless signals (431) which are received by the receivers (434) when the processing machine (30) moves, the controller (432) controlling the motor (422) to drive the driving unit (42) to drive the suction box (41) to move with the processing machine (30), so that suction airflow of the air duct (20) passes through the dust boxes (411) of the suction box (41) and the air path (412) to collect small parts and debris (A) below the processing gun (31), the control unit (43) controlling the motor (422) to drive the driving wheel (421) to support the suction box (41) to move out from the processing table (10) to clean the small parts and the debris (A).
