Description

The modification of the bucket described in patent no. 8472 for grabbing and lifting bulk materials consists in replacing a lifting hook attached to a cross member that has been connected to the buckle of the earring bucket, which is terminated by a fork with a pawl, designed to turn bearing shaft earrings.

In the schematic drawing of FIG. 1 shows a bucket front view (in open and closed position); FIG. 2 is a side view thereof.

The bucket flaps revolving on the axis xA are provided with rollers 21 (fig. 1) with straps b mounted on one end, the other end of which is mounted on the shaft 17. The stem 11 has a hinged headband with axle 13 for closing and opening the flaps a crane rope is attached; the other end of the stem ends with a fork with dog B. On the axis 13 are put on the upper ends of t g 4, having cuts in the lower parts into which the toes of the 5 bucket ears 3 pass. At the ends of the shaft 13 there are paws 15 (Fig. 2). Bearing earrings b, shaft 17, provided in the middle with a ratchet wheel 22, and at the ends with cross-pieces 9.

For loading, the bucket is lowered in the opened state supported by the rods 4, for which the crane rope with the rod P and the shaft 13 is lowered. When the legs 15 reach the crossings 9 (Fig. 2), the fork B turns the ratchet wheel 22 on the pawl, resulting in the projections of the crosses 9, they go behind the protrusions of the paws 15, having connected the rod 11 with the shaft 17. After coupling, when lifting the rod, 11 tons of 4 close the flaps of the bucket with the seized material. When reaching the unloading point, the rod 11 together with the closed bucket is lowered onto the unloading area and, as a result of further lowering of the rod 11, the paws 15 are disengaged from the crossings 9 and, when the rod 11 is then raised, the gi 4 push the bucket doors apart.
