Essence: the device contains a frame, a hopper, / dispenser, a device for dividing the fiber in the form of a body, a lattice with compression elements and suspensions made of an elastic material with strainer elements, a device for transporting the fiber. It is equipped with a pump with injection and suction piping. A method for separating the fiber is provided with a drive hollow perforated element. One ends of the hangers are fixed on the bunker. Other ends of the hangers are connected to the grill 3 sludge.

Description

The invention relates to the field of construction and can be applied to supply fiber reinforcement to a concrete mixer during the preparation of fiber concrete mixtures for concreting monolithic structures and forming prefabricated products and structures.

The closest to the invention in its technical essence is a device that includes a frame with a receiving bell rigidly fixed on it. Under it there is a device for dosing and dividing the fiber in the form of a body mounted on elastic suspensions with strain elements. In the upper part of the body there is a louvered grille, and its bottom is made in the form of two mutually inclined planes converging in the central part. A central knife and side knives are installed at the center of the planes and on the planes themselves, the height of the central knife being higher than the height of the side knives. Under the side knives is placed the feed chute, equipped with a vibration exciter

However, the known device has low productivity of feeding the fiber to the concrete mixer, since the process of fiber separation by knives with a vibration effect is not intensive enough, which also leads to the formation of lumps, and the poor quality of the mixture due to its heterogeneity.

The purpose of the invention is to increase productivity.

Constant goal is achieved by the device for feeding the fiber into the concrete mixer, which contains a hopper mounted on the frame with a dosing unit, a device for dividing the fiber in the form of a body, located in the upper part of the body under the grille dispenser with louvre elements and suspensions made of elastic material with strainer elements, a device for transportation of the fiber, equipped with a pump with a forcing and suction pipelines, a device for dividing the fiber is provided with a medium installed in the middle part of the body zvratno- translational movement vertical hollow member with a perforated work surface, facing stoSP

grate, and the injection pipe is connected to the upper part of the hollow element, and the suction pipe - with the transporting device, with one ends of the suspensions mounted on the bunker, and the other ends - on the grid.

The invention is illustrated in the drawings, where in FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - a device for splitting the fibers.

The proposed device consists of a frame 1, a hopper 2 with a dispenser, a housing 3. In the upper part of the housing 3 there is a lattice 4 on elastic shock absorbers 5 with tensor elements 6. In the lower part of the housing near the rear wall there is a hollow element 7 with openings from the front of the working side. A suction pipe — a high pressure hydraulic hose 8 with a gearbox — is connected to the inner cavity of the element 7. The upper part of the element 7 is hingedly connected with a reciprocating drive 10. Between the housing 3 and the element 7 in the lower part of the device are cellular arrays 11.

The device is equipped with a feed conveyor 12, a circulating water supply system with a pump 13 and a suction pipe.

The device for feeding the fiber into the mixer works as follows.

The fiber is fed to the device body 3 via a hopper 2 mounted on a frame.

The fiber located in the hopper 2, through its weight, acts through the closed optical grid 4 on the elastic shock absorbers 5, and those, in turn, on

one .

fl

load cells 6, through which the value of the fiber mass in the hopper is read.

After loading a predetermined amount of fiber, turn on the circulating water supply system with pump 13 and drive the reciprocating movement 10 of the hollow element 7, then open the louver 4. The fiber under the influence of elastic water jets oppositely directed in the plane of motion is divided into separate fibers, which through A cell-shaped opening 11 is fed to the feeding conveyor 12.
