Belt cleaner 7 as shown in Figure 5, its adjustment group 60 is to have vertically vertical locating rack 61 of a tabular, locating rack 61 1 sides are provided with prominent seat 62, on the prominent seat 62 plus-minus screw 63 is set, locating rack 61 the same sides are positioned at place, prominent seat 62 tops installing seat 64 are set, the strut bar 71 of scraper group 70 can wear in the installing seat 64 that is fixed in both sides adjustment group 60, again, scraping of scraper group 70 is provided with wing 702 on the tool rest 701, wing 702 tops are resisted against load-transfer device 80 belts 81 downside surfaces, and when load-transfer device 80 started rotation, wing 702 can be struck off for the foreign matter that is attached on belt 81 surfaces.

It is fixed type and only can the single direction dismounting that 60 structures are organized in this adjustment, in the time of must changing so the wing 702 on scraping tool rest 701 weares and teares to some extent, then must earlier adjustment be organized 60 whole disassembling, right Hou will be scraped tool rest 701 again and be taken out, just can carry out the replacing operation of wing 702, and change at the scene in the process of combination, again because the position of adjustment group 60 installings is vulnerable to other article and member hinders, cause whole change operation quite trouble and complicated inconvenience, and, the Hou of finishing changing wing 702, be difficult for reinstalling the original place again, and truly have the necessity that is improved.

The purpose of this utility model is to provide a kind of Belt cleaner, and it changes fast, convenient, even and the environment of erecting stage bad, also can adjust, so that install smoothly according to on-site situation.

The technical solution of the utility model is: a kind of Belt cleaner is provided, have two adjustment groups, between two adjustment groups, set up the scraper group, has locating rack in the adjustment group, locating rack is fixedly arranged on the board end face of load-transfer device downside, it is characterized in that: the bracing frame that has a square tube type in this scraper group, the bracing frame top is striden and is established the tool rest of scraping of fixing a H type section, scrape the tool rest end face and form the scraper groove, be embedded several wings in the scraper groove and fixed block be set in both sides, the positive end face upper and lower sides of the locating rack of adjustment group is provided with transverse plate, and relative up and down cover piece is set in the transverse plate, in the cover piece endoporus threaded portion is set, one screw rod spiral shell is located in the threaded portion, spiral shell is established two and is adjusted nuts on this screw rod, and following adjustment nut downside is provided with packing ring and sheathed spring, and in the outside a sheathed dust protecting cap, this screw rod upside screws out the cover piece, screw tip sets firmly a fixed frame, and fixed frame has open end, and the bracing frame of scraper group inserts and is installed in the fixed frame.

Described Belt cleaner is characterized in that: this fixed frame can be the  shape and have open end, and this open end downside is with the pivot connecting rod that is pivoted, and the connecting rod top is with the open end upside of installing screw locking at fixed frame.

Described Belt cleaner is characterized in that: this connecting rod front can be provided with set screw, pushes against the bracing frame of scraper group with this set screw.

Advantage of the present utility model is: the set fixed frame in adjustment group top has open end, and with the connecting rod sealing that is pivoted, make that the bracing frame of scraper group can be very convenient and fast speed takes out the replacing operation of carrying out wing, it does not need whole dismounting adjustment group, and on reality is used, can reach the practical effect quick, convenient and that not limited by environmental conditions that changes the outfit.

Further specify concrete structure characteristic of the present utility model and purpose below in conjunction with accompanying drawing.
