Description

The invention relates to hoisting machines, namely screw conveyors, and can be used in various industries of the industry for transporting bulk and bulk cargo. A screw conveyor for transporting bulk cargo is known, which contains a screw mounted on bearing assemblies in a trough and a drive, Cl X. The disadvantage of this conveyor during transportation of nautical goods is considerable wear of the trough and the screw at the point of contact of the load with the trough. Closest to the invention is a screw conveyor, including a screw, placed in a chute connected to a support frame, and a .2J drive. This conveyor is characterized by insufficient reliability, since the gap between the chute and the screw leads to a seizure of the load between them. The purpose of the invention is to increase the reliability of the conveyor by eliminating the NJL jamming of the load between the screw and the chute. This goal is achieved by the fact that in a screw conveyor that includes a screw placed in a chute connected to a support frame and by the water, the connection of the chute to the support frame is made in the form of a sled rammed on the support frame and vertical jacks connected at one end with a sled and the other with a chute with a groove, with the vertical jacks mounted on the sled with the possibility of moving the latter by means of a screw and a nut fixed on the support frame. FIG. 1 depicts a general view; FIG. 2 is a section A-A in FIG. 1, FIG. 3 is a section BB in FIG. 2, FIG. 4 is a section, section B-B in FIG. 2; on fig.Z - times GGG figure 1; figure 6 - node I n. Fig. D, Fig. 7 —D-D of Fig. 2 in Fig. 3 - the initial position of the groove and the position f after shifting to maintain the gap {Scom between the screw and the groove. The screw conveyor consists of a screw 1 placed in the channel 2 and supported by bearing units 3. The screw 1 is connected to the drive 5 by means of a coupling 4. The bearing assemblies 3 and the drive 5 are placed on the support frame 6 and attached to it (Fig. 1). The gutter 2 is connected to the supporting frame 6 in the form of bows 7 placed on the supporting frame 6 and vertical jacks 8 connected at one end with the slide 7, and the other hinged to the chute 2. The vertical jacks 8 are mounted on the slide 7 with the possibility of movement along the latter by means of a screw 9 and a nut 10 fixed to the support frame 6. The screw conveyor operates as follows. The rotating screw 1 in the bearing assemblies 3 by means of the drive 5 pushes the bulk load along chute 2 and displaces the load layer in the direction of rotation of the screw by angle ((Fig. 8), the value of which depends on the properties of the transported load, the parameters of the conveyor and the angle of its inclination. The angle H can be determined both calculated and experimentally. Initially, there is a nominal gap between the generatrix of the screw and the head. When transporting strong abrasive and lumpy cargoes, the screw and the chute are worn. The outer diameter of the screw will be evenly worn, and the chute will wear at the point of contact with the load being moved, and the maximum gap EL formed due to wear will be offset from the vertical by the angle Ч. The gap resulting from wear which either break down or even completely stop the screw 1 and break it; Eliminate the gap AV, J formed as a result of wear, and maintain the nominal gap between screw 1 and the groove 2 is made by moving the groove 2 in the vertical and horizontal planes. With the help of the vertical jacks 8 by moving them in the slide 7, the gap between the screw 1 of the conveyor and the groove 2 in the maximum wear sector is completely eliminated.
