<p>PROBLEM TO BE SOLVED: To provide a dust remover, in which the weight of a dust-removing scraper 10 is reduced, an angle of rotation is made small, and the rocking balance is improved. SOLUTION: Triangle frames 33 and 34 are formed in which respective vertexes are pivoted to upper and lower pivots 13 and 16. Rocking shafts 15, 18 are pivoted parallel with each other as bases of the triangle frames. A scraper having slots 19, 20 is fit correspondingly to the upper and lower shafts 15, 18. The length of the longer diameter of the slot is at least two times the diameter D of the rocking shaft.</p> |
