Description

The invention relates to industrial transport, namely, to conveyors for dry bulk cargo, and is an improvement of the device according to the author. St. No. 963936.

The purpose of the invention is to increase productivity and reliability.

FIG. 1 shows a conveyor, side view; in fig. 2 - the same, front view; in fig. 3 node 1 in FIG. 2 (fastening of the support plate to the t-belt, side view); in fig. 4 - the same, top view; in fig. 5-8 - options for supporting elements.

On the frame 1, the upper 2 and lower 3 drums are mounted. An additional frame 4 is attached to the axis of the upper drum 2; the second end of which is provided with guide rails 5 and is connected to the frame by means of an elastic strut 6. In turn, a deflecting spring-loaded drum 7. On the frame 1 after the drum 7, but along the movement of the traction belt 8, which encircles all the drums, an eccentric 9 is installed, the axis of which is placed in the guides 10 with the possibility of movement in them by means of screw pairs (not shown). The eccentric 9 is mounted on the outer side of the belt at a distance from the upper drum 2 less than the distance between the latter and the drum 7. On the outer side of the traction belt 8, carriers are mounted on its edges, made in vi / 1.e closed coils infinitely closed cylindrical springs 11. The support plates 12 are mounted on the tread band 8, located between the Ps of cylindrical springs II with a step of 30 - 35 d, where d is the internal diameter of the cylindrical spring.

Support plates 12 can be made perforated (Fig. 7 and 8), have the form of a comb (Fig. 6) or be of any other shape, for example in the form of a polygon (Fig. 5).

The upper drum 2 and the eccentric 9 are kinematically connected by the transmission 13 to the drive 14. The copier has also a receiving hopper 15 and a casing 16, to which by means of

the hinge 17 is connected to the visor with the tray 18.

The device works as follows.

A grain is loaded into the receiving bin 15 and the drive 14 is woven. A cylindrical spring 11 fixed on the pull belt 8 begins to move. In the loading zone, the outer turns of the coil spring 11 enveloping the drum 3. are diverted and capture the load. The drive to the straight section, the coils of the cylindrical spring 11 sec. Are put together, and the load is carried away in the direction of unloading. The process of seizure of cargo occurs idle branch, i.e. free from grain. In the leading branch, a constant load is supported and the load is retained by means of support plates 12. In the unloading zone, a coil spring 17 envelops the top 2 and spring-loaded 7 drums, the outer turns open and the load is ejected onto the discharge chute 18 by centrifugal force. changing the circumference angle of the upper 2 and the spring-loaded 7 drums by changing the angle of inclination of the additional frame 4 and installing the eccentric 9 in the guides 10 attached to the frame 1.

The intensification of unloading is ensured by a driven eccentric m. 9, which creates impulsive effects on the tape 8 with a spring fixed on it 11. The impulsive effects of the eccentric 9 are compensated by a spring-loaded drum 7 and turning the additional frame 4. Reliability of the bulk cargo transportation process is ensured supporting plates 12, interlaced with the interval between the coils of the spring 11. The interval between the supporting elements is 30-35 d, where d is the internal diameter of the spring.

When the step is less than 30d, the metal consumption of the conveyor and the laboriousness of manufacturing increase, and at a step above 35d, the transportation of bulk cargo to a greater height deteriorates — the bulk load column begins to fall off due to insufficient frictional forces between the load and the turns.
