The invention relates to devices for handling bulk materials along gravity chutes and can be used in all areas of the national economy.

A known installation for transporting bulk materials, comprising a pipeline, an elastic sleeve attached to its outlet end, a telescopic lowering mounted coaxially inside it in the form of conical coaxially mounted and connected by flexible connections.

nozzles, the upper of which is fixed by its large base on the outlet end of the pipeline, and the output conical nozzle fixed by its large base on the elastic arm and connected to the lower conical nozzle of the telescopic descent, and the cable-blocking system.

A disadvantage of this device is the presence of a dynamic impact of the overloaded material on the receiving surface at the initial moment.

overloading and plant operability only at pipeline transport providing. necessary pressure of the conical nozzle on the material, which is impossible, for example, when unloading silt from the conveyor belt from the bunker capacity.

The closest to the proposed technical entity is a gravitational descent containing a vertically located and associated with the drive folding chute, at the lower end of which one side is fixed to a valve rotating around a horizontal axis with a locking mechanism and a device for returning it to a horizontal position.

The disadvantage of the prototype is the deterioration of performance characteristics due to the ingress of overloaded material on the gate and its fixation mechanism.

The purpose of the invention is to improve the performance characteristics of gravitational descent.

This goal is achieved by the fact that the gravitational descent contains a vertically located and connected to the drive of its movement in a vertical plane a folding chute with a gate in its lower part, on the wall of which a level limiter and a spring lock are fixed one above the other and can be rotated around the horizontal axis - a lever with a wedge protrusion, the shutter is installed with the possibility of limited movement along the groove and fixation in the extreme positions and is located hell friend and rigidly interconnected conical and cylindrical shells, in the upper part of the latter there is a figured cut, one of the edges of which is beveled to interact with the wedge protrusion of the said lever, made T-shaped and installed with one end of its horizontal section with a stop level, and to the second end of the horizontal section of the T-shaped lever is attached the latch, while the cap is attached to the lower end of the gutter with the formation of windows in the wall Both for the passage of material, and window height

no more than the height of the cylindrical shutter shell.

FIG. 1 shows a gravitational descent in the extended position, a general view, in FIG. 2 is the same in the folded state; in FIG. 3 - section A-A in FIG. 3; in fig. 4 - node I in figure 2.

Gravity descent includes

vertically arranged folding chute 1, consisting of several links, drive 2 moving in the vertical plane of chute 1, leveling limiter 3, spring clamp 4, made in the form of a T-shaped lever rotating around a horizontal axis and interacting with one end of a horizontal

a level 3 limiter, and a wedge protrusion 5 interacting with the shutter 6 is attached to the other end. The shutter 6 is located one above the other and

rigidly interconnected conical 7 and cylindrical 8 shell. In the upper part of the shell 8 there is a figured cutout 9, one of the edges of which is chamfered to interact with the wedge 5 of the clamp 4, the lower end of the chute 1 is closed with a plug 10, and on the wall of the chute 1 there are windows 11 with a height not exceeding the shell 8 on the surface of the gutter 1

A limit switch 12 is set to control the actuator 2.

Gravitational descent works as follows.

Material from the bunker or in this

In the case of the receiving funnel, it enters the chute 1. As the gutter 1 is filled, gradually, under the action of the force of gravity of the material, the material moves out. Upon reaching the receiving surface

(the receiving surface is understood to be the bottom of any vehicle, tank or storage area) the shutter 6 moves relative to the lower end of the chute

1 upwards and opens the windows 11 and the material is poured out onto the receiving surface, at the same time the figured notch 9, interacting with the wedge 5, fixes the upper position of the shutter 6, as well as the shutter 6,

interacting with the limit switch 12, turns on the drive 2 on the rise of the chute 1. The speed of the rise of the chute 1
