SU1207963A1 - Truck unloader - Google Patents

Description

The invention relates to devices for unloading bulk cargoes from bodies of on-board vehicles, mainly grain, at receiving points of elevators.

The purpose of the invention is to increase productivity and ensure the exit of an empty vehicle from the platform.

FIG. 1 shows the truck unloader when the second vehicle is entering it, longitudinal projection in FIG. 2 is the same, view in, in FIG. 3 - car unloader from the side of entry of road trains to platforms; in fig. 4 - the same, top view, on. 5 is a section A-A in FIG. four.

The car unloader consists of a two-arm lever with platforms 1 and 2, arranged at an angle, providing self-unloading of the car or a train, for example, for grain 180 - (25-30) rigidly attached to axis 3, which, in turn, is connected to a fixed frame 4 by means of hinges (bearings) 5.

In order to limit the inclination angle of platform 1 and .2, support cams 6 are designed. The platform 7 is lowered with car 7 by hydraulic cylinders 8, the piston cavities of which are interconnected by pipeline 9. The truck 10 is operated by valve 10, which can be remotely controlled. To exit a car with a tilted platform., Are the inclined ramps 11, which along the line to the inclined platforms have in the transverse direction the same angle of inclination as the platforms 1 and 2, and then gradually

the transition t in horizontal stigost, providing a smooth exit of the car 7 with the lowered platform on the earth's surface. Safety is ensured by the lateral sides 12. To fix the platforms in the desired position, the car unloader can be equipped with a brake pulley 13 mounted on axis 3 and brake pads 14 10 with the drive lever 15.

The unloader works as follows.

A load, for example, grain, grain

Car, coal 7 enters the horizontally located platform 1, rigidly connected with platform 2 and through axis 3 and the hinge 5 with the frame 4. At the same time, valve 10

blocked off When the side sides of the car are open, the valve 10 is opened, regulating the amount of hydraulic fluid 8 flowing through the pipeline 9, thereby ensuring a smooth lowering of the platform 1. Under the force of gravity, the auto-. Mobile 7 platform 1 tilts fully against the support cams 6. Valve 10 is shut off. When lowering platform 1, platform 2 comes to a horizontal position and is ready to receive the next car loaded. At the end of the unloading, the car 7 is moving forward along ramp 11, which has the same transverse tilt angle as platform 1 along the line to platform 1, moves out of it and drives out onto the earth's surface. The valve 10 is opened again and platform 2 is lowered with another car, and platform 1 is horizontal and ready to receive the next vehicle load. The cycle is repeated.

Claims (2)

1. CAR UNLOADER, comprising a frame on which a two-arm lever is mounted on a horizontal axis with rotation, a vehicle platform is mounted on one shoulder, the arm of the lever being at an obtuse angle to each other, characterized in that, in order to increase productivity, it is equipped with an additional platform mounted on the other shoulder of the specified lever. 2. Car unloader according to π. 1, characterized in that, in order to ensure that the empty vehicle exits the platform parallel to the specified axis, the section of the frame on the exit side is made inclined upward to interface with the horizontal surface of the frame.
