Description

The invention relates to devices for finishing building products and can be used in the building materials industry, in particular in the finishing of building products made using face-up technology with crushed materials, such as rubble of various rocks.

A device for laying crushed materials is known, which includes a self-propelled portal on which the feed hopper is mounted and the Cil drum feeder mounted below it, however, this device does not provide uniform, dense material placement across the entire surface of the product.

Closest to the present invention is a device for finishing the surface of building products, containing a bunker mounted on the frame, "placed under it by an hingedly fixed upper end an inclined tray with a vibration exciter 2.

The disadvantage of the known device is the unevenness of the application of the finishing material.

The purpose of the invention is to improve the quality of products by ensuring uniform application of the finishing material.

This goal is achieved by the fact that the device for finishing the surface of building products, containing a bunker mounted on the portal, an inclined chute fixed with an upper end hinged with an excitation of vibrations, equipped with a device for changing the tilt angle of the tray, is kinematically connected to the vibration exciter, the hinge end of the tray is hinged mounted on the portal and has a drive of its vertical movement, and the upper end is connected to a device for changing the angle of inclination.

On the self-propelled portal 1, moving over the product 2, the bunker 3 with sector gates 4 divided into compartments, opened Е1МН using pneumatic cylinders 5, also eccentric wave 6, driven by the rotation of the belt gear 7 from the drive with speed variator 8. Under the hopper 3 is inclined trays 9 with the exciter. The lower ends of the trays are connected by hinges 10 to the beam 11 (figure 2 which is attached to the portal 1 by means of screw rods 12, which allows the necessary clearance to be set between the tray and the product. Vertical oscillations I receive the upper ends of the trays from the eccentric shaft 6 through the beam 13 and t 14. To ensure the possibility of turning off oscillations of any of the trays, the coupling of the rod 14 with the beam 13 is accomplished with the help of a conical pin 15 moved by the cylinder 16 relative to the lug 17. The change of the angle of inclination of the trays is 14 talps on the rails 14. To vary the oscillation amplitudes of the trays, the eccentric VS 6 transmits vibrations to the beam 13 through an eccentric sleeve with an end tooth 19, which is fixed relative to the shaft using the coupling half 20, keys 21 and nuts 22. For a uniform distribution of material across the width slit-mounted feeders are installed 23. The device works as follows: In the compartments of the hopper 3, for example, marble siphon is loaded, after which the pneumatic cylinders 5 open the sector gates 4 and pour the required amount of materials on the surfaces of trays 9 bounded by slit-type feeders 23. The gap in the slit-type feeder is set depending on the size of the material being laid and its consumption. The drive is switched on with the rotation speed variator 8 and through the belt drive 7, the eccentric gear 6, the key 21, the coupling half 20 and the eccentric sleeve with the end tooth 19 transmit the oscillations to the ball 13. Adjust the required amplitude of the oscillations due to the mutual reversal of the eccentric shaft 6 and an eccentric sleeve 19. A reversal fixation, and therefore a certain amplitude of oscillation, is carried out by pressing the nuts 22 of the front teeth of the coupling half 29 onto the front teeth of the sleeve 19, the coupling half 20 being connected to the shaft 6 by the key 21. Screwing and and unscrew the gi 12, set the necessary clearance between the lower end of the tray 9 and the surface of the product 2. Regulators using. with a speed variator 8 speed oscillations of the trays, as well as using tarpes 18 lengths t g 14, and, consequently, the angle the tilting of the trays is achieved by a single-layer, uniform and as dense as possible movement of the finishing layer on the trays. When the finishing layer reaches the bottom edge of the tray, the portal 1 begins to move over the product 2, according to its speed of movement with the speed of the finishing layer on the tray, thereby obtaining its single-layer and maximum density on the product. When it is necessary to interrupt the laying of the finishing layer while bypassing the openings, one of the pneumatic cylinders 16 is inserted, which pushes the conical pin 15 out of the conical hole of the eyelet 17, thereby disconnecting the kinematic connection between the beam 13 and the leg 14, and consequently, the tray. The proposed device makes it possible to mechanize the process of laying textured material, to improve the quality of finishing the product. As a result, according to the decorative properties and durability, this type of finish is practically not inferior to the finishing with ceramic tiles, at the same time it is much less labor-intensive (not 3-4 times) and cheaper (by 3-4 rubles per 1 m of the surface of the product). ) The invention The device for finishing the surface of building products, containing a bunker mounted on the portal, housed under it by an upper end an inclined tray with oscillation pathogen. Characterized by the fact that, in order to increase the quality of the product by ensuring uniform application of the finishing material, it is equipped with a device for changing the tilt angle of the tray, kinematically connected to the vibration exciter, the lower end of the tray is pivotally fixed on the portal and has a drive for its vertical movement, and the upper end connected to a device for changing the angle of inclination.
