SU740667A1 - Apparatus for unloading loose and lump materials from vehicles - Google Patents

Description

The invention relates to the field of loading and unloading operations, in particular, to devices for unloading bulk and lump materials from vehicles.

A device for unloading bulk and lump materials from vehicles is known, comprising a self-propelled carriage carrying a dump conveyor associated with lifting and turning mechanisms, an intake working body made in the form of a scraper conveyor closed in a vertical plane, enveloping guide sprockets, an actuator and a supporting bracket intake working body 1.

The design of the working body of the known device during unloading. transport vehicles with different widths of the body requires numerous maneuvers.

The aim of the invention is to increase the efficiency of work.

For this, the device is provided with vertical posts articulated in the middle part to said bracket, with said stars being attached to the free ends of the racks.

FIG. 1 - the proposed device, a general view; in fig. 2 - intake working body.

The device contains a self-propelled carriage 1 with a lifting mechanism 2 installed on it, and a dump conveyor 3, to the bed of which a tilt angle mechanism 4 is connected.

On the base of the conveyor 3, the intake working body 5 is hingedly fixed by means of an axis 6 passing through

15 eyelets triangular bracket 7a 7.

Coupled pivot posts 8 are connected to the bracket 7, the midpoints of which are provided with hinges 9, and guides are mounted at the ends

20 asterisks 10, bending around with tug chains 11 with buckets 12 and brushes 13 fixed between them.

To be able to change the length of the intake part of the working body when

25 of the same length of the traction chains 11, the pillars 8 with the reinforcement on the ends of the star gear x 10 are designed in such a way that in the vertical plane the traction chains form an equilateral

thirty

trapezoid, with the hinges 9 located on the center line of the trapezoid,

To rotate the pillars 8 around the hinges 9, to change the length of the intake part of the working body 5, in the upper part of the pillars 8 are kerchiefs 14 with grooves 15 that have the rollers 16 fixed on the nuts 17. The nuts 17 are in meshing with the lead screw 18, equipped with left and right threads and reducible: the drive mechanism 19 rotates mounted on the bracket 7. The kerchiefs 14 with grooves 15, the rollers 16, nuts 17 and the lead screw 18 with the drive 19 form a double-sided screw-screw mechanism.

The traction chains 11 of the intake working body 15 bend around the drive sprockets 20, which are mounted on the same shaft with an asterisk 21, attached to the rotation of the chain gear 22 from the sprocket 23. drum 25 dump conveyor 3.

For tensioning the pull 11 and drive 22 chains, tension devices 26 and 27 are mounted, respectively.

To prevent cargo from spilling from the upper branch of the intake working body to the upper ends

3 are pivotally attached pallets 28, one of which is provided with guide grooves 29, and the other with four finger rollers 30 entering

in engagement with the grooves 29.

The device works as follows.

With the help of self-propelled trolley 1, lifting mechanism 2 and mechanism

4 changes the angle of inclination of the intake working body 5 is installed above the body of the vehicle with a load.

In this case, the lower branch of the intake working body 5 is set horizontally. Further, with the help of a double-sided screw-screw mechanism, the length of the intake part of the tool is adjusted.

5 according to the width of the vehicle body. At the same time, during the rotation from the actuator 19 of the screw 18, the nuts 17 on it move symmetrically or move apart, and the rollers 16 fixed to the nuts 17 act on the inclined grooves 1 of the gussets 14 and turn the pair of pillars 8 in the right direction. Pcic racks 8 stars

10 rolls along the traction chains 11.

Due to the fact that the working body 5 in the vertical plane is made in the form of an equilateral trapezium, and the hinges 9 rotate the pillars 8 are located on its middle lines of the stars 10 while mirroring the racks 8 make equal, but oppositely directed movements, providing a constant total length of the traction chains 11 when changing the length of the lower branch.

After adjusting the length of the intake part of the threaded member 5, the dump conveyor 3 is turned on.

5 From the driving drum 25 of the dump conveyor 3, by transferring 24 via pulley-sprocket 23, chain drive 22 and sprocket 21 are driven into rotation by driving

0 stars 20 t beef chains 11.

During the movement of the traction chains, 11 clips-scoops scoop up the bulk material, lift it up, and through the trays 28 serve for unloading into

5 receiving tray dump conveyor 3, which lays the bulk material either directly in a riot, or transfers it to other transport mechanism.

Brushes 13, mounted on the traction chain 11, facilitate the cleaning of the underbody at the end of unloading.
