Detailed Description
The embodiments of the present invention will be further explained with reference to the drawings.
Referring to fig. 1-2, a novel belt conveyor scraping device comprises two felt scrapers 1 and two dust hoods 2, wherein one felt scraper 1 is fixed on the left side of the left dust hood 2 through a clamping plate 3, the other felt scraper 1 is fixed between the two dust hoods 2 through the clamping plate 3, and the felt scraper 1 is fixed on the clamping plate 3 through a bolt 4. The felt scraper blade 1 is directly placed on a belt 5 of a belt conveyor through gravity, the dust collection cover 2 is supported and fixed above the belt 5 through the felt scraper blade 1, and angle steel 6 used for limiting is arranged at four corners of the dust collection cover 2 (the angle steel 6 can be arranged on a rack of the belt conveyor, and the felt scraper blade 1 and the dust collection cover 2 can not move along with the belt 5 due to the arrangement of the angle steel 6). The bottom surface of the felt scraper 1 is abutted against the working surface of the belt 5, and a first gap 7 is arranged between the bottom of the dust collection cover 2 and the working surface of the belt 5. Two dust hoods 2 are the same in structure, are equipped with four airflow distribution plate 8 in the dust hood 2, and airflow distribution plate 8's length direction is unanimous with the width direction of belt 5, and on dust hood 2's left side inner wall was located on the top of leftmost airflow distribution plate 8, its bottom right slope and with dust hood 2 right side inner wall formation binding off, the area of binding off equals the half of dust collecting opening of dust hood 2. The right side of the rightmost airflow distribution plate 8 is provided with a partition plate 9, the top end of the partition plate 9 is connected with the top end of the rightmost airflow distribution plate 8, and the bottom end of the partition plate is inclined rightwards. The plane of the airflow distribution plate 8 is intersected with the plane of the belt 5, and the smaller included angle of the two included angles is A, wherein A is more than or equal to 45 degrees and less than or equal to 90 degrees. In this embodiment, included angles a formed by the four airflow distribution plates 8 and the belt 5 are not equal, and sequentially increase from left to right, where a corresponding to the leftmost airflow distribution plate 8 is 45 °, and a corresponding to the rightmost airflow distribution plate 8 is 90 °. The arrangement can ensure that airflow channels 10 with wide top and narrow bottom are formed between the adjacent airflow distribution plates 8 and between the partition plates 9 and the dust collection cover 2, and the pressure of the negative pressure airflow is instantly increased when the negative pressure airflow enters the airflow channels 10, so that the adsorption force of the negative pressure airflow on the adhesive material on the belt 5 is enhanced, and the material blockage in the dust collection cover 2 can be prevented.
And second gaps 11 are arranged among the bottoms of the air distribution plates 8, the bottoms of the partition plates 9 and the working surface of the belt 5, and gaps 12 are formed among the bottoms of the adjacent air distribution plates 8.
