Description

The invention relates to brick making machines provided with endless chain boundless forms that pass under pressure rollers and then under an eccentric ejector. In the proposed brick making machine, an endless chain was used to receive bricks pushed out of the molds onto the base pads and to drop the pads with the bricks onto the cross conveyor, consisting of squares with folding shelves. This transverse conveyor is equipped with a device for raising the under-knob with bricks, driven from the pedal.

In FIG. 1 is a side view of the machine; FIG. 2 is a side view of the link of the conveyor with a raised mechanism; FIG. 3 is a top view of a chain link with a folding shelf; FIG. 4 is the same, front view.

The proposed brick making machine (Fig. 1) consists of a series of bottomless molds connected into an endless chain 7 and passing under several pressing rollers, and then under an eccentric ejector. An infinite chain 3, passing under the upper half of the chain 7 of the forms and composed of coal / 4 with folding spring-loaded shelves 5, was used to accept the bricks pushed out of the molds onto the sanding lining and to drop the latter along with the bricks onto the cross conveyor 2; this chain moves twice as fast as chain 7 (Figs. 3 and 4).

To lift the linings with bricks at the conveyor 2 there is a device (Fig. 2), actuated by pedal 6 and consisting of a gear wheel 7 with radial slots 8, in which there are sliders connected by rods 9 with eccentric W.

The frame 77 of the machine is made of wooden bars bolted together. Under the transverse bars 72 of the frame, trolleys 75 are installed to move 1 arschine along the drying sheds. If it is necessary to transfer the car to another plant, carts 75 are re-installed under the longitudinal bars of the M frame.

The upper bars x75 of the frame 7 / are fitted with a riveted sheet of iron with clay 76, the back wall of which is attached to the bolts for removal in case of repair of the internal mechanism.

Inside the clay locks (along its length) two shafts 7 /, rotating one towards the other, with six blades, which must pick up, knead and push the clay out to the exit, pass.

At the rear ends of the shafts with clay, the locks are fitted with gears 75, coupled

between each other and on one of them, more elongated, three more gears are mounted for changing speeds and Pulley 20 are for transmitting movement from the conveyor shaft. The clay front end of the J6 has a rectangular shape and a width of three bricks too long, and a height slightly greater than the thickness of the bricks; At the exit of the clay, two guides are embedded for cutting the common ribbon into three parts and two iron rollers 2 / with a peripheral speed equal to the speed of the ribbon (clay). The rollers have a gap between them to reduce or increase the thickness of the tape. To slide the ribbons from the rollers to the bars, m 75 reinforced copper sheet 7P.

Under the copper sheet. There is a chain made of angular and sheet iron, representing bottomless brick forms; this chain is driven by square wooden drum 22.

Four wooden rollers 23, upholstered with iron, rotating at a circumferential speed equal to the speed of the chain and with the direction of movement along the latter, are installed above and below the upper half of the watch chain. On the upper bars x / 5 there is a mechanism for pushing the raw material out of the molds.

Ma.shchina acts as follows. Clay-laden cars on an inclined platform and with the help of special leads are attached to the hook of the chain and fed with a follower to the platform where they unload J6 or the platform directly into the funnel.

At the same time, water is supplied from the tank, the amount of which is regulated by a tap.

In the clay block J6, the clay, mixed with water, is kneaded and pushed out in the form of a ribbon from under the shafts 77 located above and below the outlet of the clay clay.

Immediately between the rollers, the wide vent is cut into three ribbons, the width of which should be slightly larger than the thickness of the raw material.

The ribbons from under the rollers on the 7P copper sheet come under the first upper chain roller 23, which presses the ribbons approximately by half

Into the forms of the chain, the speed of which is regulated by the movement of the belt on the conical drums, according to the clay output.

The second upper roller 23 presses the ribbons into the forms completely, and the lower roller compares, according to the shape, the lower planes of the raw brick.

With the passage of the watchtow chain, the ejector mechanism begins to push the raw out of the molds with its shoes; the raw material is finally pushed out when the shoes approach their lower position.

An ejected brick (three pieces in a row) falls on a wooden plank lying on the folding shelves of a chain that runs below the drawer chain and falls on the conveyor belt. The moment of approach of the planks to the raw material falling on them is regulated by gears from a gear train from the square drum 22 of the watch chain to the square drum of the chain for feeding the boards.

After the board falls on the conveyor, this chain approaches the square 4 with shelf 5, which with its slope puts the folding shelf of the square (link) of the chain to the normal position for passing over the square drum.

Boards with raw material, located on the conveyor, pass to the elevating mechanism. Standing at this mechanism, the tenant presses the pedal 6 of the mechanism and the board is lifted first at one end of the frame of the mechanism, approximately to half, and then due to inertia, from its weight and speed, rolls along the rollers to the stop.

Then the tenant, lowering the pedal 6, removes the board and lays it on the table or machine next to it, from which the boards are taken to be placed on the pole in the drying shed.

The subject matter of the invention.

1. Brick making machine using endless forms connected in an endless chain, passing under several pressing rollers, and then under an eccentric ejector, characterized in that for accepting bricks pushed out of the forms onto backboards and for (Blowing down the linings with bricks on The cross conveyor 2 uses an endless chain 5, passing under the upper half of the chain of 7 forms and made up of squares 4 with folding spring-loaded shelves 5 and moving twice as fast as the chain of forms 2. With the machine as described in 1 application in the conveyor 20 of a device for raising the liners with bricks, actuated by a pedal b and consisting of a gear wheel 7 with radial slots 8, in which there are sliders articulated by connecting rods 9 with an eccentric 10.
