RU178232U1 - PORTABLE RATTER FOR SOWING CONTAMINATED CRUSHED GRADDLE - Google Patents

Abstract

During the production of track works, in particular when cutting local splashes, there is a need to replace contaminated gravel with clean ones. Sifting contaminated gravel through a wire sieve does not give the desired cleaning, so clean gravel is transported to the work site in advance, and dirty gravel is thrown onto the side of the subgrade. Sifting crushed stone with this screen allows to reduce time and save crushed stone.

Description

The technical field to which the utility model belongs.

The utility model relates to railway transport and is intended for mechanization of manual labor when removing ballast from railway sleepers and sifting contaminated rubble.

As the closest analogue (prototype), a source of information was used (see GB 1576386 A, 10/08/1980, B07B 1/42, 8 s, / 1 /). A portable vibrating screen is known from this source, including a bed (pos. S) with an electric motor (pos. M) mounted on it with a pulley on the shaft for transmitting torque to the eccentric shaft (pos. H) through a belt drive (pos. L), a removable screening device (pos. A) having a grating bottom and made with the possibility of installation on a moving frame of hollow tubes (pos. C) by means of a frame located under the bottom of the tray and acting as the frame stops (pos. B).

Disclosure of a utility model.

The technical result consists in mechanization and an increase in the productivity of manual labor when performing track work.

The result is achieved by a portable screen (vibration stand) for screening contaminated rubble containing a rectangular support frame on which an internal combustion engine (ICE) is mounted, transmitting rotation through a belt drive to an eccentric shaft, mounted in double-row bearing housings, and fixed to the eccentric part of the shaft along its edges two bearings placed in a pipe on which longitudinal rails are mounted, mounted on the other end to the springs, in turn mounted on the support frame, and on the longitudinal On the slats there are two cross members that form a moving frame, with a distance between them equal to the size of the box (stretcher) with a trellised bottom, between which stretchers loaded with contaminated rubble are placed.

According to a utility model, the frame, made in the form of a rectangle, has two short sides and two long sides, in order to place ICE, housings for double row bearings, springs and handles for carrying the screen on it.

According to a utility model, a pulley for a belt drive is mounted on the ICE shaft.

According to a utility model, an eccentric shaft is placed in double row bearings.

According to a utility model, a pulley for a belt drive is attached to a protruding end of an eccentric shaft.

According to a utility model, two bearings are located on the eccentric portion of the shaft.

According to a utility model, two bearings are placed in a tube to which two longitudinal rails are attached, interconnected by two cross members, thus forming a movable frame.

According to a utility model, the longitudinal rails are supported by shock absorbers.

According to a utility model, two crossbars are installed on the longitudinal rails to place a box (stretcher) between them.

According to a utility model, the stretchers have a trellised bottom and carrying handles.

According to a utility model, the stretchers have one side rim with an outward inclination of the stretcher, which makes crushed stone more easily spilled out of the stretcher.

According to a utility model, there are protrusions in the lower part of the stretcher on the side of the handles to prevent the stretcher from creeping during the sinking process.

Brief description of the photo

The claimed utility model is illustrated by the photograph of FIG. 1, which shows a screen (vibration stand) and a stretcher implemented in a preferred embodiment.

Utility Model Implementation

The portable screen (Fig. 1) consists of a steel rectangular frame 1, on which an internal combustion engine 2 is installed, on the shaft of which there is a pulley 3 for a belt drive 4, having a tensioner 5. On the bed, also, on one side of the case (6) are installed with double bearings for the eccentric shaft, and on the other, shock absorbers (7), on which the movable frame is mounted 10. A pulley 8 is mounted on the end of the eccentric shaft, to which torque is transmitted using a belt drive 4 from the pulley 3. The eccentric part of the shaft is placed in the bearings, located in the pipe 9, and the movable frame 10 is fixed to the pipe with cross members 11, between which stretchers 12 with contaminated rubble are installed, having stops 13 that prevent the stretchers from sliding off the frame.

Sifting contaminated crushed stone is as follows.

The engine starts first. Then, a stretcher, filled with contaminated rubble, is installed on a movable frame between the cross members so that the stops located at the bottom of the stretcher encircle the longitudinal sides of the frame. Engine speed can be increased. Due to the amplitude of vibrations of the moving frame, gravel is sieved in a stretcher. Sifted rubble spills back into the path. If necessary, the movable frame can be extended, with the expectation of installing another stretcher on it.
