[0005] The disadvantage of this technical solution is the limited ability to regulate the supply of concrete mixture during the unloading process, which makes it difficult to carry out work that requires precise dosing of the mixture.

[0006] Also known is a bucket for laying concrete mix according to USSR Author's Certificate No., containing a container for concrete mix and a device for unloading it (SU 487218, IPC E04G 21 / 04, B28B 13 / 02, published 07.08.1975).

[0007] The disadvantage of this technical solution is the insufficient accuracy of regulating the consumption of concrete mixture when filling forms and formwork, as well as limited ability to ensure uniform supply of highly mobile concrete mixtures.

[0008] The objective of the claimed utility model is to create a dispensing bucket for concrete mixtures that provides controlled supply of concrete mixture, reduces material loss during unloading, and increases ease of use and operational reliability.

[0009] Disclosure of Utility Model

[0010] The technical result consists in reducing the probability of spontaneous leakage of the mixture, reducing concrete losses during unloading and increasing the operational reliability of the dispensing bucket.

[0011] The technical result is achieved in that in a dispensing bucket for concrete mixtures, containing a welded metal body with an upper cylindrical part and a lower conical part, turning into a cylindrical neck with a through hole, a support frame, mounting loops and a device for regulating the supply of concrete mixture, a sector valve is installed inside the cylindrical neck, made in the form of a rocker-type valve and connected to a drive that ensures a change in the flow section of the through hole and an adjustable supply of concrete mixture, wherein the cylindrical neck is made with the possibility of attaching an additional funnel, a distribution tray or a sleeve.

[0013] The essence of the utility model is explained by drawings.

[0014] Fig. 1 shows a general view of the declared dispensing bucket, Fig. 2 shows a top view of the declared dispensing bucket, where:

[0015] 1 - welded metal structure,

[0016] 2 - vertical reinforcement elements,

[0017] 3 - support frame,

[0018] 4 - horizontal stiffeners,

[0019] 5 - cylindrical neck,

[0021] 7 - sector shutter,

[0022] 8 - manual lever drive,

[0023] 9 - mounting hinges.

[0024] Implementation of a utility model

[0025] The concrete mix dispensing bucket comprises a welded metal body (1) with a cylindrical upper section and a conical lower section that transitions into a cylindrical neck (5). A through hole (6) is made in the lower part of the cylindrical neck (5) for discharging the concrete mix.

[0026] The housing (1) is mounted on a support frame (3). The upper part of the housing (1) contains mounting loops (9) designed for lifting and moving the dispensing bucket using lifting mechanisms.

[0027] A sector valve (7), designed as a rocker-type damper, is installed inside the cylindrical neck (5). The sector valve (7) is connected to a drive (8), which opens, closes, and regulates the flow cross-section of the through hole (6) for feeding the concrete mixture.

[0028] The cylindrical neck (5) is designed with the possibility of attaching an additional funnel, distribution tray or sleeve, ensuring the supply of concrete mixture to hard-to-reach areas, forms or formwork.

[0029] Special cases of implementation of a utility model

[0030] In one embodiment, the drive (8) is a manual lever. In other embodiments, the drive (8) may be pneumatic, electric, or hydraulic.

[0031] To increase the strength and rigidity of the structure, the body (1) can be equipped with vertical reinforcement elements (2), and the support frame (3) - with horizontal stiffeners (4).

[0032] In one embodiment, the inner surface of the housing (1) is provided with a lining made of a composite material with a low coefficient of friction, which helps reduce the adhesion of the concrete mixture to the inner surfaces of the housing and improve its descent.

[0033] The lower part of the support frame (3) can be provided with elements for gripping with forklift forks, allowing the dispensing bucket to be moved without using a crane.

[0034] The body (1), support frame (3) and / or horizontal stiffeners (4) can be made of rolled metal in the form of a pipe, angle or channel.

[0035] Preferred technical characteristics: total volume - 1.2 m 3 , working volume - 0.8 m 3 , height - 1700 mm, diameter of the upper cylindrical part - 1400 mm, diameter of the drain hole - 190 mm, sheet material thickness from 3 mm.

[0036] The operation of the dispensing bucket is as follows.

[0037] The concrete mix is ​​loaded into the housing (1) through its open top. Once loaded, the dispensing bucket is moved to the concreting site using a lifting mechanism using the lifting eyes (9) or transported by a forklift with the appropriate gripping elements.

[0038] To discharge the concrete mix, the drive (8) moves the sector valve (7), changing the cross-sectional area of ​​the through hole (6). Depending on the opening of the sector valve (7), a controlled, batchwise or continuous supply of concrete mix is ​​ensured. After the mold, formwork, or other receiving container is filled, the sector valve (7) is moved to the closed position, stopping the supply of concrete mix.

[0039] The proposed design provides adjustable supply of concrete mixture, reduced material loss during unloading and increased ease of operation of the dispensing bucket.

[0040] The dispensing bucket is assembled in a factory setting on a jig to ensure precise geometry. It uses crane equipment, specialized clamps, and jigs, with full engineering and technical support. All welds are checked for compliance with GOST 23118-2019 "Steel Building Structures. General Specifications." After the structure is handed over to the quality control department, it is sandblasted, powder coated on all areas that will not come into contact with the alkaline environment of concrete mixtures to increase service life, and marked with the inventory number, volume, weight, and locations where lifting mechanisms may be hooked.

[0041] For the manufacture of a dispensing bucket, steel grade St3 according to GOST 34329-2017 is preferred.

[0042] Working with a dispensing bucket for architectural concrete does not require special skills.

[0043] The stated technical solution ensures controlled portioned delivery of highly mobile architectural concrete mixtures, increases the accuracy of filling forms and formwork, reduces the loss of concrete mixture during unloading and improves the reliability of the dispensing bucket.
