Description

one

The invention relates to the field of application of transport and relates to devices for transporting and dumping piece goods.

A device for transporting piece goods is known, which contains a main two-price conveyor with cargo carriers, by their traverses in the form of kinematically interconnected endless flexible element of rollers, and an additional conveyor located parallel to the main one.

This device can, if necessary, discharge cargo during transportation, but it has the following disadvantages. The location of the additional conveyor on the side of the main one does not allow one to dump the load in this direction, i.e. the device will only drop the load in one direction. The presence of a large number of sprockets, shafts, bearings and bevel gears for the kinematic connection of the cargo-drying, their traverse with an additional conveyor greatly condition the design of the device.

It is also known a device for transporting and dumping piece goods, comprising a main conveyor with load-carrying cross-arms 2.

The disadvantage of this device is the low reliability of the device due to the wear of the rollers when they are rotated in different directions, snake-like movement of the load, which leads to unloading of the load with a bias and the appearance of a blockage. In addition, the discharge of the load is hampered by the fact that the load may be stuck on the fences covering the roller table stars or on the roller supports.

The aim of the invention is to improve the reliability of the device.

This goal is achieved by the fact that the device is equipped with an additional conveyor with fixed angles to

its longitudinal axis with copiers located inside and parallel to the main conveyor, each of the load carrying beams made in the form of rollers with an endless flexible envelope around them,

having pushers for interacting with copiers.

A device for transporting and dumping loads of bulk loads comprises a main double-chain conveyor 1, the chains of which move along guide rails (not shown). Attached to the chains of conveyor 1

TpgMpcbi, OctoHiuue FROM frame 3, rollers 4 and 5, kinematically interconnected, with an endless flexible element (chain, cable, etc.) 6 with pushers 7. Elements 6 move along guide rails (not shown) that perceive the reactive load. Parallel to the main conveyor 1 and an additional conveyor 8 is mounted inside it. It consists of a traction chain, to which rigidly and at an acute angle (for example, 45 °) copiers 9 are attached to the longitudinal axis of the conveyor. Copiers 9 have fingers 10 placed in grooves of trough-shaped guides AND (fig. 3), along which the copiers slide 9. Such a design of the copiers prevents their turning in the horizontal plane when reconciled. and operating with pushers 7. Conveyors 1 and 8 are located relative to each other in height so that the upper level of copiers 9 is above the lower level of pushers 7 located on the lower branch of the infinite flexible element 6. This allows copiers 9 to interact with the pushers 7 with relative movement of conveyors 1 and 8. Copiers 9 are plates, to the bottom surface of which fingers 10 are attached. The number of pushers 7 is chosen so that when the contact is left with copier 9 one pusher, another pusher A spruce might get in touch with the next copier. To reduce frictional forces on the pusher 7, rollers (ball bearings) with a vertical axis of rotation are mounted

The device works as follows.

Conveyors 1 and 8 are driven from their drives at equal speed, i.e., they move synchronously. On the cross-arms 2 of the conveyor 1, there is a load (for example, a log) which moves in the longitudinal direction. Since both conveyors move at the same speed, the copiers 9 do not interact with the pushers 7.

If necessary, dump the load onto the side, disconnect the drive of the conveyor 8. The conveyor 8 stops. Conveyor 1 continues to move. In this case, the pushers 7 abut against the fixed copiers 9. As a result of the inclined installation of the copiers 9, the pushers 7 begin to move along the surface of the copiers 9, moving in the transverse direction the endless flexible elements

four

6. The load, which is located on the rail 6, as a result of this is dropped to the side (to the right, Fig. 3). After the load has been discharged, the drive of the conveyor 8 is switched on again, and the transverse movement of the elements 6 with the pushers 7 is stopped.

To discharge the load to the other side (to the left), the drive of the conveyor 1 is disconnected. Conveyor 1 is stopped. Copiers 9, which are not displaced in the longitudinal direction by the conveyor 8, come into contact with the pushers 7 and displace them in the transverse direction. Together with the pushers 7, the elements 6 also move, dropping the load to the other side (left). After the load is reset, the conveyor 1 drive is turned on again. With this method, the conveyor 1 is idle during the load discharge. If you drive the conveyor 8 2 speed,

it will be possible to drop the load to the left without stopping the conveyor 1. For this, the conveyor drive 8 switches to another, increased speed, without disconnecting the conveyor drive 1. The conveyor 8 starts moving

faster than conveyor 1, which causes the copiers 9 to interact with the pushers 7 and, therefore, the load is dumped to the left. After the resetting process is completed, the drive of the conveyor 8 is switched to the previous speed, and the movement of the pushers 7 in the transverse direction is stopped.
