In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a scraper drum of scraper position adjustable, includes toper platform and scraper, scraper evenly distributed is at the lateral surface of toper platform, be provided with between scraper and the toper platform and adjust the seat, adjust the seat and fix the lateral surface at the toper platform, the scraper is pegged graft and is adjusting in the seat and the scraper is adjusting the seat portable regulation.

As the utility model discloses a preferred technical scheme, adjust the seat package rubbing board body, bar groove and through-hole, the one end of plate body and the lateral surface fixed connection of toper platform, the inside division of the other end of plate body has the bar groove, the size and the scraper looks adaptation in bar groove, the upper and lower both ends in bar groove run through have two at least through-holes, the upper and lower both ends of scraper run through have with the quantity of through-hole and the corresponding round hole of size, through the stay bolt fixed connection who passes through-hole and round hole between scraper and the plate body, stay bolt's screwed up fixedly through lock nut.

As an optimal technical scheme of the utility model, the quantity of through-hole is four, and four through-hole evenly distributed are at the upper and lower both ends in bar groove.

As an optimized technical scheme of the utility model, the plate body is provided with the inclined plane with link one side of toper platform.

As an optimal technical scheme of the utility model, it is fixed through welding mode between seat and the toper platform to adjust.

Compared with the prior art, the beneficial effects of the utility model are that: this scraper drum of scraper position adjustable compact structure, reasonable in design, occupation space is little during the use, can require the distance between adjustment scraper and the basket according to the installation, has improved and has used the commonality, through with the scraper bar inslot removal in adjusting the seat, can change the extension length of scraper, and then change the distance between scraper and the basket, need not to reprocess new scraper drum, greatly reduced manufacturing cost.
