Abstract

The invention relates to a conveyor industry, namely to devices for cleaning spills from under the conveyor. The purpose of the invention is to increase the reliability of operation of the device on conveyors with a concave part of the route. The device for cleaning spillage from under the conveyor includes a section of collecting tape, the envelope of the deflecting roller, forming a loop area.

The invention relates to a conveyor structure, namely, devices for cleaning spills from under the conveyor, and can be used on conveyors having concave sections in their middle part.

The aim of the invention is to improve the reliability of the device on conveyors with a concave area of the track.

Fig, 1 shows a device, side view; in Fig „2 - the installation site of the separation roller;, on FIGURE 3 - view A in Fig. 2; in FIG. 4 is a diagram of the interaction of the sled of the upper branch with the separating roller when idling; in fig „5 - the same, during the operation; Fig. 6 is a diagram of the interaction of a sled of the lower branch with a separation roller when idling; in fig - the same, when working

The device for cleaning the spill from under the conveyor consists of a section of collecting tape 3 loosely laid on the bearing surface 1 of the conveyor 2, which bends around the deflection roller 4 in the head part of the conveyor 2, forming a loop loop section 5 7, traction ropes 9 and 10 are attached to the sled 6 and 7 by means of chain-mounted attachments 8, which skirt the diverting units 11 and 12 and are stored on the drums of the double-drum (scraper) winch with the additional reduction gear 13, the deviation The driving roller 4 is fixed above the discharge funnel (bunker) of the conveyor 2,

Along the conveyor 2. to its frame (racks} 15 are attached guide rails 16 with a height of 100-150 mm from the supporting surface 1. Between the upper branch of the device formed by the collecting tape 3 and the cable 11 and the lower forming by the same collecting tape 3 and separator rollers 18 are installed in the zone of the concave portion 17 of the conveyor 2, and are mounted on two flat springs 19 and 20 by the second ends of the springs .19 and 20 mounted with brackets 21 on the frame 15 of the spring conveyor 2 19.20 oriented towards the tail 22 of the conveyor 2 and interconnected U-shaped gesture

frame 23, spanning with the gap 24, the upper branch 3, 10 of the section | tape; Each of the flat springs 19, 20 is designed for the force i P SiSin (ft / n), where S is the maximum tension of the collection tape 3J & - the bend angle of the conveyor track; n is the number of separation rollers 18 on the inflection point (for example, n 2.3), and the stroke of its free end approximately equal to a height of 6.7 (100-150 mm):

The device for cleaning the request from under the conveyor is as follows.

The spillage formed during the operation of the conveyor 2 accumulates on the collecting tape Zo. As it is filled, the winch 13 is turned on, which with the help of the hauling rope 9 provides the movement of the collecting tape 3 and its unloading from the spill, and with to initial positioning The centering of the collection tape at the working and idling strokes is carried out due to the interaction of the slides 6 and 7 with the longitudinal guides. When the collecting tape 3 moves in the direction of the deflection roller 4, the spillage located on the tape 3 is discharged into the discharge funnel .14 of the conveyor 2

With the passage of the tape 3, traction ropes. 9, 10, sal 6.7 in the area of the concave section 17 of the conveyor 2, the upper 3, 10 and lower 3, 9 branches of the tape segment do not interact with each other, but interact with the separation rollers. At idle (tape 3 returns to its original position a) the lower arm 6 and the upper branch carriage 7 (figs. 4 and 5), attacking the separator roller 18, deflect it up or down, overcoming the elastic force of the springs 19, 20 during their deformation and constituting the tension of the upper or lower branches of the device: when the sled 7 races on the roller 18 moves downwards also to 9, and when the sled 6 runs onto the roller 18 together with it the rope 10 moves upwards. Due to this, cases of jamming and hard blows are prevented during the interaction of the sled 6.7 to the roller 18, since the latter sinks or floats when passing the sled 7 or 6, respectively The skew of the roller 18 during the deformations of the springs 19, 20 is eliminated due to the presence of a rigid U-shaped frame 23, which jointly fixes the ends of the springs 19, 20, ensuring their joint deformation by the same amount. During the working stroke (Figs. 5, 7), the passage of the slide 7 and 6 through the separating roller 1B is carried out in the same way as described. The gap 24 between the U-shaped frame 23 and the upper branch of the tape section ensures the free passage of the tape 3 with the PROFILE
