! 30 upper, at the same time as a dropping device '{-.'. serving roles m led that the, foreign! Sides of the ascending belt strands a ¹ touch each other. The conveyed material is ^{pressed between the belts α 1} and lifted. In order to press the bands against one another, support rollers b are arranged. The capacity is increased in a known manner by attaching edges c to the belts a. These can butt against each other (FIG. 2) or, as FIG. 3 shows, overlap in such a way that the shaft-like conveying space remains closed even when the belts hit. The performance: ■ ability can be increased significantly in a manner that is also already known by attaching projections, e.g. B. angle iron d (Fig. 3, 4 and 5). The conveyed goods are lifted into boxes, as it were.

According to the present invention, these strips end quite evenly at the bottom by being guided over end rollers h at the same height. The device is suspended so that they BEZW. the weight of the lower rollers h rests on the mass of grain to be lifted. The belt parts running around the rollers h act like rollers on the grain in that they tend to drag the grains along. Since the two rollers h rotate in opposite directions, the grains are drawn into the narrow space between the two belts. In this way, the bulk material is lifted without the need for shoveling or dumping, as long as there is only enough grain under the rollers h and the entire lifting device will sink or be slackened.

Claims (1)

so that it always rests on the grain. The dropping of the conveyed bulk material can be done in a known and arbitrary manner, e.g. B. through horizontal guidance of a strand e according to FIG. 6. It is also possible create a release device by rrian that the upper belt pulleys m, corresponds Bßfeehand of Fig. 6, arranged one above the other ίο and the lower belt through a guide roller η (Fig. 7 and 8). For higher funding heights it will often be advisable to divide the entire route into several subdivisions disassemble. Here, according to FIG. 8, the ejection device from FIG. 7 can be reversed be arranged as a collecting device. May be, for lifting and lowering the pick-up rollers h, the bands a, as shown in FIG. 9 ao shows, in the known of single ligaments forth manner pulley-like / lead over displaceable guide rolls, the belt pulleys can be adjusted h by the upward or downward movement. This movement of the two rollers must always take place simultaneously in the present lifting device, which can be brought about in different and arbitrary ways. The lifting of the take-up rollers h can be brought about in the simplest manner if a braking or locking device for the belts is arranged between the movable rollers / and the take-up rollers h. For this purpose, for example, on the sections g to h, two cylindrical or non-circular rollers can be used for each band, which usually allow the band to slide through unhindered, but if they come closer to one another or the non-circular rollers are rotated against each other, the relevant one Pinch the tape firmly between you. Since the belt tries to move further in the direction of the arrows, but is held at one point, the loop surrounding the roller h shortens, i.e. it lifts it while the loop lengthened at α , which naturally causes the guide roller I to sink. After releasing the braking device, the take-up rollers h descend again and the displaceable rollers I are raised. · You can also train the guide rollers g themselves to brake rollers, as shown in FIG. 10. If the brake pads g ^{1 are} pressed on, the take-up rollers h are raised. In order to easily remove the superfluous support rollers b when lifting, but to be able to distribute them accordingly when lowering, two of the support rollers b are combined in a frame i (FIGS. 11 and 12). which can also accommodate two other roles k at the same time, which are used to guide the downward running belt strands. The rollers are in this case expediently arranged so that, as shown in FIG. Ii and blank 12 detect the rising, but, k on the one hand on the other together with the rollers, direct the downwardly moving Bandtrume b. These frames / hang at certain intervals on ropes or chains ^. When the take-up rollers h are raised, the individual frames line up automatically; when they are lowered, they are distributed according to the lengths of the chain sections. The b in a frame i lying rollers and k to press against the bands, they can be stored displaceable in its frame and either, as shown in FIG. 13, the rollers b with each other and the rollers also k interconnected by tension springs connect barren this Connection, as shown in FIG. 14, between each roller b and the non-adjacent roller k . · "■; '■ Patent claims: I. Lifting device for bulk material with two belts without end, the rising strands of which hold the bulk material between them, characterized in that both belts run at the lower end without lateral deflection around equally high-mounted rollers (h) and that these rollers '. load on the bulk material, for the purpose of an automatic detection of the bulk material to be achieved without shoveling. , 2. Lifting device according to claim I, characterized by the activation ■ from pulley-like, simultaneously movable guide rollers (I) into the path of each belt, in order to .! and lowering the lower intake '■■;' to allow both belts to roll (h). 3. Lifting device according to claim 1 and 2, characterized in that a braking or locking device for the belts is arranged between the movable rollers (I) and the receiving rollers (h) , for the purpose by which Belt movement itself to be able to raise the take-up rollers (h). 4. Lifting device according to claim 1 and 3, characterized in that the locking or braking device (g ^l ) is connected to the guide rollers (g), which roll the receiving-115 (h) feed the belt. 5. Lifting device according to claim 1 and 2, characterized by a number of loosely lying on top of one another, connected by chains or the like. Frame (i) for receiving support rollers (b) and ge given case of guide rollers (k) for the descending belt strands (a), which frame (i) also descend in accordance with the lowering of the take-up rollers (h) by gradually taking the distance from each other limited by the chains or the like. 6: Lifting device according to claim i, characterized in that each gwel in. support rollers (b) at the same height and two guide rollers (k) each also at the same height, or one of two support rollers (b) at the same height with one of two guide rollers (k) at the same height by springs in the sense the Aripressurig are connected to the associated band strands. 1 sheet of drawings.
