Description

one

The invention relates to industrial equipment intended for organizing mobile production of building products, mainly from local building materials.

A device for the manufacture of building products is known, including an anchor frame do stanina, a compression-pressing mechanism with a form, loading and unloading mechanisms, a device for moving the product, made in the form of rigidly paired platforms, a drive and control devices fl.

The disadvantage of this device is the need for a large number of forms and complexity of operation in connection with the possibility of concrete blockage of platforms.

The purpose of the invention is to simplify operation.

The goal is achieved by the fact that the device for the manufacture of building products, mainly ground blocks, includes a support frame with a frame, a sealing-pressing mechanism with a form, loading and unloading mechanisms, a device for moving the product, made in

the form of rigidly coupled sections, the drive and control devices, the form being made with detachable boards, the lower parts of which are hingedly fastened to the upper parts, the attachment sections are made in the form of platforms that are spaced apart from each other by a distance of not less than the height of the boards.

The feed unit includes an electrically operated bucket elevator 3, an attachment for a mock 4, a bunker 5 and a tray 6 for dumping soil into a mold. Attached when mock

5 4, where the soil, delivered from the development site, is unloaded, is installed with a rail towards the elevator 3 and has access bars. The hopper dispenser 5 has a folding bottom with a spring-loaded electromagnetic E 1mkom

and provided with a load limiter in the form of a level switch.

The compression unit includes a mold fixed on the bed 7, made in the form of a rectangular open box 8 with split walls. Upper - fixed part of the duct - pivotally connected to the lower part, consisting of four sides 9, tilted to the top. The flaps have edges and locks, which in the working position are connected to each other and to the pallet 10. The mold has two interchangeable pallets, rigidly connected by a drawbar 11 and capable of simultaneously moving along the guide rails 12. The reciprocating movement of the pallets by means of a cable. output t g from reversible electric motors 13 and 14.

The internal dimensions of the mold at the level of the hinged sides correspond to the parameters of the blocks produced (for example, 50x100 BF cm). The full volume of the form, counting up to the upper edge, is calculated on the maximum specified norm of loosened soil.

The punch 15, made of a thick steel sheet with radial stiffeners, is in the initial position above the mold, opening a passage for the bed to fall asleep. Along the vertical guides mounted on the bed 7, the punch is capable of lowering and raising with the help of cable tg reversing electric drive 16. On the punch. the vibrator 17 is reinforced. The punch 15 with the vibrator 17 forms a flat pressing mechanism. The vibrator receives a command to turn on the device 18.

The unloading mechanism is an electric -console crane 19, located at the mold with the calculation of the alternating discharge of pallets put forward on opposite sides. The turning angle of the crane is 21 (fc, and the load capacity corresponds to the weight of the manufactured blocks (for example, 600 kg) "Semi-dry soil blocks 20 are removed from the pallet and loaded onto a number of standing vehicles by means of a lever-hinge pickup 21, exerting pressure on the body of the block no more than 0.4 kg / dm.

The power source of the electrical installations of the device is the regional electric grid with a voltage of 380/220 V. In the case of its remoteness from the work site, an independent power supply from the alternator with a capacity of 10-15 kW is used.

The remote control unit 22 allows you to remotely regulate the main production operations.

sequentially performed by automated installations of the device.

 The device works as follows.

J The elevator 3 switched on from the control panel 22 captures the loosened soil from the ground 4 and lifts it into the metering hopper 5. When the bin is filled to the specified volume

The Q triggers a level switch to shut off the elevator motor drive and the ground feed stops. At the same time, the level switch energizes the electromagnetic lock, which opens the bottom of the hopper 5 and the measured dose.

 the soil is poured over tray 6 into the mold.

When the forward stroke of the electric drive 16 is turned on, the punch 15 is lowered, and the entrance to the mold, the limit switch turns on the vibrator, which compresses the soil. When the punch reaches the lower limit line, the end switch is triggered, stopping the operation of the vibrator AND including the return stroke of the electric drive 16, raising the punch to its initial position. At its rise, the punch captures the gf, lifting the bottom of the metering hopper 5 in

Q initial position fixed

electromagnetic lock. The punch itself is fixed in a similar way, after which the end switch is activated, turning off the electric actuator 16 and turning on the actuator 13, with which the flaps 9 are raised.

When the end boards are in the upper position, the end switch is activated, which turns on the electric motor 14, which extends the pallet 10

0 with a molded block for unloading-. ki In this case, the second pallet, rigidly connected with the first, takes its place under the mold.

After that, the final is triggered.

5, a switch that turns off the electric motor 14 and turns on the electric motor 13 again, but already on the lowering of the sides of the mold, which are again fastened to the next pallet.

0 For subsequent blocks after this operation, the electric drive of the elevator 3 automatically switches on and the production cycle repeats, varying only the alternate supply of blocks to opposite sides, which is regulated by automatic switching of the forward and reverse stroke of the reversing electric drive 14.-.

Simultaneously with the implementation of the first

In two operations, the ground unit is unloaded and removed from the pallet by an electric crane 19 with the help of a special grab 21 and is loaded onto a number of vehicles transporting ready-made blocks to a building object

where they are applied to the wheels with the help of a self-propelled forklift (for example, a K-32 truck-mounted crane, UP-0.5 and UP-Tuo unified loaders, and others), also equipped with a special type 21 grip.

With such a combination of preparatory and unloading operations, the operation of the device is simplified and its productivity increases.

The proposed device is advisable to use in rural household unions (fcoBhozes, collective farms) and in construction enterprises, where mass raw construction of houses, fences and other buildings is carried out by hand.
