Description

Apparatus for loading unit loads onto a belt conveyor is known, including a tray mounted on the receiving end of the conveyor.

A distinctive feature of the described device is that it uses a scraper pusher mounted on a spring-loaded slider, which converges in a swinging vertically suspended on the frame. The slider is locked in a raised position by a pawl that releases the slider when the scraper is located behind the block cut by a stone-cutting machine. The device of this design provides a forced feed unit on the belt conveyor. In addition, for the purpose of automatically raising to idle position and releasing the slide in the device, a scoop hinged on the frame is used, interacting with the cage swings with a fist or roller mounted on the slider, as well as a double-arm lever interacting with the unit and a spring-loaded slider pulling the dog. The drive of the rocking clip can be made in the form of a curvature-shatunnogo mechanism.

FIG. 1 shows schematically the described device, side view; in fig. 2 - the trigger mechanism.

The frame is hingedly suspended by a holder made in the form of a cylinder /, within which a spring-loaded slider 2 moves, carrying a scraper pusher 3 at its free end. A pawl 4 is mounted on the swiveling cage, which is spring-loaded with a flat spring 5 and interacts with the protrusion 6 of the slider. A clip with a slider by means of a connecting rod 7 and a bent rod 8 is driven in a swinging movement relative to its hinge 9. A roller 10 is mounted on the slider, which, interacting with the hinged

on the frame with a pin //, it ensures the rise of the ram when it is idle. In the extreme upper position of the slide, its protrusion 6 enters the engagement with the dog. When the working stroke of the slide, the // pin, which acts as a guide copier, rotates through a certain angle relative to the joint 12. The shank of the pawl 4 interacts with a spring-loaded slide 13, which is coupled with the double-shouldered lever 4, which rotates about the axis 15 with a block 16 (load) with moving stone cutting machine (not shown).

At the end of the slide stroke, a belt conveyor 17 is installed, at the receiving end of which a tray 18 is mounted for transferring cargo thereon onto the conveyor belt.

The slide cage continuously oscillates by means of a crank mechanism.

The pusher, entering the vertical gap between the block cut by the stone-cutting machine and the face, moves the block along the curvilinear tray from the bottom to the belt conveyor while moving to the left. During the return movement of the clip with the slider, the roller of the latter, rolling along the guide of the copier, raises the slider to the upper position. At the extreme upper point of the slide stop protrusion., Interacting with the dog. When advancing a stone-cutting machine along the bottom, the lever 14 of the trigger mechanism, resting against the end of the cut stone (block), moves the slider 13 under the upper shoulder of the doggie. During the next pitching of the yoke to the right, the dog rests against the slider 13 of the lever 14 and releases the slider 2, which, under the action of its weight and the compressed spring 19, moves downwards. At the same time, the pusher grabs the next block and, moving to the left, feeds it onto the conveyor belt.

The described device can be used in combination with stone-cutting machines in quarries for the production of limestone sawn stone.

Subject invention

Claims (4)

1. A device for loading on a belt conveyor of piece loads: iOB, for example a block cut by a stone-cutting machine, includes a tray mounted on the receiving end of the conveyor and intended to push it onto the submersible block tape, characterized in that, for the purpose of forcibly advancing the block, A pusher in the form of a scraper mounted on a spring-loaded slider, moving in a vertically suspended on the frame of the tilting cage and held in a raised position by a spring-loaded pawl, was released ayuschey slider at the location behind the scraper unit. 2. The device according to claim 1, characterized in that for raising the scraper to the upper idle position, a guide is used, made in the form of a pin, fixed on the device frame, pivotally with the possibility of deflection upwards at a limited angle and interacting during the swings of the yoke with salivating on the slider fist or roller. 3. The device according to claim. 1 and 2, characterized in that for the automatic release of the slider a double-arm lever is mounted on a)), which, when its lower arm stops in the block, interacts with the upper shoulder with the slider pulling the pawl. 4. Device on PP. 1-3, characterized in that a crank mechanism is used for the wheel 1 and the yoke.
