Detailed Description

In order to clearly understand the technical features, objects and advantageous effects of the present invention, the following detailed description of the embodiments of the present invention is given, but the present invention is not limited to the applicable scope.

As shown in the figure, the powder metallurgy dust removal device comprises a conveyor 1, a roller 2, a collection necking 3, a fixed seat 4, a threaded hole 5, a bolt 6, a main rod 7, a steel ring 8, an installation clamping piece 9, a scrubbing brush 10, an I-shaped frame 11, a spring 12, a sliding sleeve 13, a connecting rod 14, a top frame 15, a through hole 16, an overflow bolt 17, a bearing 18, a roller brush 19 and a cover 20; the device is characterized in that the front end of the conveyor 1 inclines upwards to increase the sliding speed of the blank, so that the blank is prevented from being clamped by the scrubbing brush 10 and the roller brush 19, and the falling metal dust can fall into the collecting throat 3 at the bottom of the conveyor 1 in a small gap between the adjacent rollers 2 and finally fall into a collecting container arranged below the collecting throat 3; the fixed seats 4 are welded on the left side and the right side of the conveyor 1, and threaded holes 5 are formed in the tops of the fixed seats; one end of the main rod 7 is welded with a steel ring 8 and is rotatably arranged on the fixed seat 5 by a bolt 6, and the main rod 7 is welded with an installation clamping piece 9; the scrubbing brush 10 is fixed on the mounting clamping piece 9; the I-shaped frame 11 is welded on the conveyor 1 outside the fixed seat 4, and the left end of the I-shaped frame 11 is sleeved with the spring 12, and the right end of the I-shaped frame is provided with the sliding sleeve 13; the two ends of the connecting rod 14 are respectively hinged with the right end of the main rod 7 and the sliding sleeve 13, the main rod 7 where the scrubbing brush 10 is located is matched with the sliding sleeve 13 which is acted by the spring 12 through the connecting rod 14, and the scrubbing brush 10 can be adjusted according to the blank and tightly attached to the surfaces of the left side and the right side of the blank to remove metal dust attached to the surfaces of the left side and the right side; through holes 16 are formed in the left end and the right end of a cross beam of the top frame 15, and cap bolts 17 are installed in the through holes 16; the cap bolt 17 is sleeved with a spring 12, the bottom of the cap bolt is welded with a bearing 18, a roller brush 19 is rotatably arranged on the bearing 18, and the cap bolt 17 can be tightly attached to the top surface of the blank passing through under the action of the spring 12 and can remove attached metal dust.
