Description

BACKGROUND OF THE INVENTION SKIPS are known that are discharged through an oblique bottom with an automatic hydraulic shutter turning from the rollers that slide along curves, specially curved, guides. In the proposed vertical prismatic skip shape, a movable tilting tray is used, which is connected to a cylindrical shutter and slides along rollers fixed in brackets.

In FIG. 1 shows a skip front view; FIG. 2 is a side view of it; FIG. side of the open skip; FIG. 4-different positions of parts of the skip during its filling.

The proposed vertical skip (Figs. 1 and 2) has a prismatic shape and is discharged through an oblique bottom with a cylindrical gate F and a movable tilting tray I. The gate F. consists of two sector-shaped cheeks D, between which the shaft B is reinforced, which serves to hang the whole gate to body C of a skip rigidly associated with frame A.

The Skip Case C is a rectangular box with a bottom, directed at an angle of 45 °, which mates with the rear wall along an arc of a circle; the side walls have a slight narrowing at the bottom, and the front is scrap 176,

smooth view. In general, the design of the hull is similar in its motion to the tilting jug skip. Coal during the filling of the skip falls on the curved wall and slides to the bottom, which, due to its rounded shape, absorbs the kinetic energy of the coal by braking. Thus, the advantage of a glass skip, in the sense of the smallest crushing of coal, is partly related to the proposed skip.

On the inclined bottom of the housing C, bearings 3, which are one bearing of the bolt, are strengthened. The bottom of the tray (or a special stop), on which the lower edge of the cylindrical shutter flap lies, serves as another support.

Tray A is an ordinary chute with high side walls. The hinge of the 2ndG serves as one support for the chute, connecting it with the sect-shaped cheeks D of the gate with the help of an axis fixed in the latter; as another support are the rollers T, mounted on the axis K, which with its ends is fixed in the brackets G. The latter serve simultaneously as a cushion for the landing carriage of the metering loading device, as well as a measure

against bursting the sides of the tray during its emptying, for which they are connected with the ZZ / interlacing plate. Stiffness is attached to the bolt by fitting to each other arcuate guide bars H, which are riveted on the side edges of the outlet orifice and, accordingly, on the cheeks of the bolt. This system, due to its rigidity, is guaranteed against distortions and loosening, as a result of which the loose fit of the constipation is eliminated, and hence the sinking of coal. This disadvantage cannot be completely eliminated in other types of skips that are emptied through the bottom, since their closures consist of trays suspended by cantilever with the help of hinges fixed on the exit edge of the inclined bottom of the skip. Such trays, due to their cantilever effect, are prone to skewing from the impacts of the loaded coal, as well as loosening the hinges, due to their work in the coal.

On the sect-like cheeks D of the bolt, with the help of the axis I, strengthened between the cheeks, unloading rollers E are fitted, which serve to turn the closing mechanism around the axis B,

The opening of the slide F and the simultaneous pushing and tilting of the tray occurs automatically with the help of rollers E, guided by curved guides. five.

The principle of the skip (Fig. 4) is as follows. When the skip approaches the place of unloading, the discharge rollers E enter the curved guides B, as a result of which the bolt F starts to rotate from its initial position upward along the arc described around the center of the axis of rotation of the bolt. opening the outlet itself to empty the skip. The hinge G linking tray L with gate F also begins to move nd arc described from the same center B, and the other end of the tray rolls along the rollers T supporting it. At the beginning of the gate deflection at a small angle (Fig. 3, position II) the skip outlet remains closed due to the fact that the arc length of the cylindrical valve is 100–120 mm longer than the arc length of the outlet, until the tray is above the hopper. When the shutter F opens with an emptying outlet for emptying the skip, the bottom of the tray L will be at an angle of 45 ° to the horizon above the bunker (position V of Fig. 4).

After the skip is emptied, the unloading rollers E descend from the curves of the guides B and set the entire closing mechanism to its original position.

The subject matter of the invention.

Vertical prismatic-shaped skip, unloading through an oblique bottom, with an automatic cylindrical shutter, turning from rollers sliding along curves, specially bent guides, characterized by the use of a movable tiltable tray L connected to a cylindrical shutter F using a hinge G (Fig. 1 and 2) and sliding along the rollers T, reinforced in brackets G.
