Abstract

Auger lift, including a screw fixed on the axis and a The baffles are characterized in that, in order to increase productivity, it is provided with a rectangular stand in which a screw with an axis is placed, while the baffles are fixed on the inner walls of the stand in pairs on both sides of the screw and parallel to the walls of the stand.

Description

 and

The invention relates to lifting equipment, namely screw conveyors, and can be used in various industries to transport parts such as rings.

A screw elevator is known which contains a rotating axis on which a one-way auger is attached, two guide sheets in contact with the upper section of the screw and connected on one side with the inlet, and on the other with feed path tl.

A disadvantage of the known screw elevator is the low productivity, since it does not ensure the loading of products from two opposite sides of the auger and their simultaneous transportation by a turn of the rotating auger.

Closest to the invention is a screw elevator comprising an auger fixed on the axis and partitions C23.

The disadvantage of this device is the inability to ensure the loading and placement of objects on two opposite sides fixed on the central axis of the partition and their simultaneous transportation by a screw on both sides of it, which reduces the performance of the auger lift.

The purpose of the invention is to increase the productivity of the screw elevator .V

This goal is achieved by the fact that the screw lift, which includes a screw fixed on the axis and partitions, is equipped with a rectangular stand that holds the screw with the axis, while the partitions are fixed on the inner walls of the rack in pairs on both sides of the screw and parallel to the walls of the stand.

FIG. 1 schematically shows a screw lift, a general view; in fig. 2 is a view A of FIG. one; figure 3 view B in figure 1; in fig. 4 shows a section B-B in FIG. one.

The screw lift contains a rack 2 mounted on a stand 1 with a screw 3 placed inside it and a kryshka 4 fitted on its upper part, on which the drive 5 is mounted. Stand 1 is made in the form of a square tube with a flat base,

two opposite gtenka of which windows are made for sabbds of rings located diagonally opposite to each other. 5 A rack 2 is made of two channels 6, a pair of partitions 7 is attached to the wall of each of them on its inner side, and between channels 6 there are placed fixed from the side) 0 their ends 8 of the housing with bearings 9. In the lower and upper parts of the wall of each channel 6, respectively, the opening window for the rings and the exit window for the rings are made 15 diagonally. Channel 6 is installed so that their shelves are facing each other, with this window for setting rings in both channels 6 are located diagonally opposite to each other, and the window for exit rings in these center / Ilera 6 are similar. Blow-offs 7 are installed in pairs on both sides of the screw 3 and are arranged parallel to the shelves of corresponding 5 channel channels 6. Each

the pair of partitions 7 forms with the corresponding and parallel shelves of channels 6 channels a cavity for housing and transporting parts;

Q open from the side of the screw 3, the width of which corresponds to the width of the transported ring. The screw 3 is complete with a pitch of its turn somewhat larger than the outer diameter of the transported ring, and the turn height corresponds to the width of the right ring. The screw is mounted with the ends of its shaft in the bearings 9 of the housing 8 inside the rack 2. The rack 2 with the screw 3 is installed in the square tube of the stand 1 so that their opening windows for the rings are aligned. The lid 4 is made in the form of a tetrahedral glass with a central hole in its bottom, and in two opposite walls of which are arranged diagonally opposite each other windows for exiting the rings. Krshka 4 is installed on rack 2 so that their windows for exit of the rings coincide. The actuator 5 is mounted on the cover 4 so that its output shaft 10, passed through the central hole in the bottom of this cover 4, engages with the corresponding end of the axis

5 screws 3.

Screw lift works as follows.

When the drive 5 is turned on, its output shaft 10 transmits rotation to the screw 3. When the turns of the rotating screw 3 are reached, the corresponding window for entering the pillars of the rack 2 comes from the unloading trays of the process equipment (not shown) to the rings for rolling the pedestal 1 and the pillar 2 into the interturn gap of the screw 3 and are placed inside the rack 2 from different sides of the axis of the screw 3 in the cavity formed by each pair of partitions 7 and the corresponding wall of the stand 2 corresponding to it. The partitions 7 y erzhivayut ring against rotation around the axis of the screw 3, with the last rotation. With further rotation of the screw 3, I will apply my turn to the rings.

transports them up. In this case, each ring is moved by a failure of the outer cylindrical surface along the wall of the corresponding channel, 6 pillars 2. When the rotating spiral auger 3 reaches the level of the corresponding window to exit the pillar rings 2 rings, through the corresponding windows to exit the pillar 2 and crinkle 4 rings, they roll into the loading equipment jjoTKH (not shown).

The invention makes it possible to provide loading and placement of rings on two opposite sides of the screw and their simultaneous transportation by a turn of the screw of the screw, which improves the performance of the screw hoist as a whole.
