The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
Present embodiment is provided for the first road clearing apparatus of band conveyor.With reference to Fig. 1, this clearing apparatus is located at main shaft 3 on these two permanent seats 1 with comprising the rotatable frame of left and right two permanent seats 1, two ends, be installed on the tool rest 5 on the main shaft 3 and be installed on scraper 6 on this tool rest 5.The blade of scraper 6 is oblique to the lateral deviation by belt conveyor roller, and the two ends of main shaft 3 are installed on two permanent seats 1 by two changed course devices 2.The effect of changed course device 2 is that the blade of scraper 6 61 is pressed on the belt with certain pressure, to remove the material that adheres on the belt.
See figures.1.and.2, this changed course device 2 comprises intermeshing first gear 23 and second gear 24, described first gear 23 is fixedly connected on the described main shaft 3, described second gear 24 is fixedly connected on the balancer shaft 27, this balancer shaft 27 is provided with radially a weight linear meter 25, and this weight linear meter 25 is provided with a clump weight 26 that can balancer shaft 27 be rotated by himself weight.The skew direction of the blade 61 of scraper 6 and the bearing of trend of weight linear meter 25 are opposing, under clump weight 26 actions of gravity, weight linear meter 25 is to lower swing, drive counterweight 27, second gear 24 by anticlockwise direction rotation shown in Figure 2, thereby make first gear 23 by right-hand revolution shown in Figure 2, thereby make scraper 6 by right side beat shown in Figure 2, and hold out against on belt.When the material that adheres on the belt is 6 of scrapers can't remove the time, scraper 6 overcomes the gravity of clump weight 26 to left swing shown in Figure 2, allows this bur, resets under the effect of clump weight 26 then.
With reference to Fig. 3, its changed course device 2 comprises that one is fixedly installed in the gear case 21 on the permanent seat 1, and described main shaft 3, balancer shaft 27 are installed on the two side of gear case 21 by two bearings 31,32 and 271,272 respectively, outside each bearing 31,32,271,272.
With reference to Fig. 1 and Fig. 4, be installed with a strut bar 4 on this main shaft 3, the diameter of this strut bar 4 is greater than this main shaft 3, and described tool rest 5 lower parts are nested to be installed on this strut bar 4.This tool rest 5 is provided with a dovetail furrow 50, and described scraper 6 bottoms are provided with the swallow tail 62 that cooperates with this dovetail furrow 50.
With reference to Fig. 2 and Fig. 5, changed course device 2 tops are provided with a holdback 7, this holdback 7 comprises that one is fixedly set in the sleeve 71 on the gear case 21, be slidingly equipped with a positioning rod 72 in this sleeve 71, one end of this radius stay 72 is towards the center of described first gear 23, and this end forms a check protuberance 74, and this check protuberance 74 stretches between two teeth of first gear 23, the opposing side of itself and scraper 6 skew directions forms the curved surface 741 with gear mesh, and opposite side forms a vertical plane 742.That is to say, as Fig. 2 and shown in Figure 5, if do not consider belt to the stopping of scraper 6, but first gear, 23 right-hand revolutions then, but the anticlockwise direction rotation is subjected to certain limitation.This holdback 7 can prevent that larger-size material particles from entering between scraper 6 and the belt and make scraper 6 excessive beats and cisco unity malfunction.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
