Description

A mobile hydraulic press installation for briquetting medicinal raw materials (e.g., poppy boxes) mounted on the rear part of the truck frame or dump truck using hydraulic pumps of the engine group to drive the pressing device is proposed.

The known installations of this type, with the use of a pressing device and the subsequent dressing of pressed bales with string or briquettes into sacking, do not provide the possibility of briquetting medicinal raw materials directly in the field, with successive holding of briquettes in dies outside the press under pressure.

This drawback is eliminated in the installation being described in that its power part, consisting of successively paired cylinders, is hydraulically connected through the main line and the hydraulic distributor to the pump of the motor group of the truck driving the hydraulic press. The latter is mounted on a vertical support frame mounted at the rear end of the car body and made in its lower part detachable and pivotally connected to the upper part of the support frame. At the bottom of the frame there is a platform for detachable matrices automatically locked with a lock, which are moved during the pressing process along a roller table mounted under the support frame and a hopper for loading the press.

FIG. 1 shows a general view of the installation from the side; FIG. 2-behind; in fig. 3 shows a general view of the matrix from the rear in fig- 4-top; in fig. 5 is a longitudinal section along the arrow L in FIG. four.

The installation (Fig. 1-2) consists of a car 1, a vertical support frame 2, working cylinders 3, a hydraulic circuit 4, a hydraulic distributor 5, a rod 6 of a cylinder and a punch 7, a bunker and detachable dies are not shown in the drawing.

The support frame 2 of the hydraulic press, made of I-iron, is mounted in the rear part of the car body, is supported by the side legs on the ends of the dump truck frame and is bolted to them. The frame consists of an upper fixed part and a lower part pivotally hinged, which, when moving the machine from place to place, is swiveled and placed on the body in a horizontal position. Before work starts, the fittings are installed in a vertical position and fixed with a stopper. At the bottom of the movable part of the support frame there is a plate; there is a flat for installing matrices on it.

The hydraulic pump of the motor group of the motor vehicle is connected by an oil pipe to the working cylinders 3 through a hydraulic distributor 5 from a forklift truck, which is located at the starboard side of the body; on the opposite side, a bunker is hung on the body to load the pressurized medical raw material. A roller table (not shown in the drawing) is mounted under the bunker and both press frames, along which empty and filled matrices move.

The matrix consists of three walls 8-10, of which two walls 8 and 9 are moved apart on hinges, held together, all three walls. The corners are welded to the walls of the matrix, providing the required strength of the matrix. In the lower part of the side walls, longitudinal slits are made to automatically fix the matrix cover by means of a lock. The loops //, welded in the frontal part to the side walls of the matrix, and the pins 12 fasten the side walls of the matrix in a flattened state before briquetting.

Together with the bottom, laid on the shelf of the lower square, the pressed raw material is poured into the assembled matrix, the matrix is closed with a cover 13 and substituted for briquetting under the plunger of the press working cylinder. The lid with the punch moves down and locks in the lower position with automatic locks 14 welded to the lid. After that, the pressure is released, the punch is lifted and the die is removed from under the press to hold the briquette out of the press under pressure. in terms of volume or weight of the pressed material, it is moved along the roller table to the working cylinders and installed on the lower platform of the press frame. By turning the knob of the hydraulic distributor, the pressurized oil is directed to the upper part of the cylinder, with the result that the piston moves down. At the same time, the punch of the press presses on the lid of the die and follows in it the compressible raw material to a volume corresponding to the briquetting mode. The lid of the die, fitted with an automatic lock, is automatically fixed rigidly in the lower position, after which the oil is supplied to the lower part of the working cylinder by switching the hydraulic distributor, with the result that the piston rises up.

On this, the pressing operation is completed. The matrix is removed from the press, and the process of aging under pressure does not occur under pressure, as usual, but in the matrix itself.

Subject invention

A machine for briquetting plant raw materials, for example, poppy boxes, using a pressing device and then wrapping compressed bales with string or tying briquettes into bags, which in order to briquette medicinal raw materials directly in the field with subsequent aging of briquettes in matrices outside the press under pressure, the power part of the installation, consisting of successively working twin cylinders, is hydraulically connected through the oil pipe and the hydraulic distributor with the pump of the motor group g a motor vehicle driven by a hydraulic press mounted on a vertical support frame mounted at the rear end of the car body and made in its part detachable and pivotally connected to the upper part of the support frame, at the bottom of which there is a platform for detachable matrices automatically locked with lock that are moved the pressing process on a roller conveyor mounted under the support frame and a hopper for loading the press.
