Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to the technical field of a concrete metering device. Background Art

[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. The term concrete usually refers to cement as the cementitious material, sand, stone as aggregates and water in a certain proportion, which are mixed and obtained by mixing. It is also called ordinary concrete.

[0003] In the process of preparing concrete, raw materials need to be added in proportion. Generally, special concrete raw material metering equipment is set up to ensure the accuracy of the ratio. At present, a Chinese patent with announcement number CN218504829U discloses a raw material metering device, including a frame, on which a plurality of metering buckets are slidably installed on the crossbeam of the frame, and the feed port at the upper end of each metering bucket is lower than the discharge port at the end of the mixing device on the frame; the metering bucket includes a bucket body, and the inside of the bucket body is divided into two storage chambers by a quantitative plate fixed to the bucket body; a discharge nozzle is inclined at the lower end of the bucket body corresponding to each storage chamber.

[0004] In actual use, it is difficult to fix the quantitative plate, and its stability cannot cope with the impact of raw materials, especially stones. Secondly, the weighing bucket does not take into account that the raw materials will appear in a cone shape when falling into the weighing bucket, rather than being ideally spread flat in the entire weighing bucket. This has a great impact on the measuring accuracy and use effect. Utility Model Content

[0005] The utility model provides a concrete metering device to solve the above technical problems. It realizes convenient and efficient arbitrary adjustment of the volume of the metering bin, is more stable during use, and can finally lay the raw materials evenly in the metering bucket, making the metering more accurate.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A concrete metering device comprises a mounting frame, a material storage bin, a first bin door, a first hydraulic cylinder, a metering bin, a second hydraulic cylinder, a third hydraulic cylinder, a second bin door and a fourth hydraulic cylinder, wherein the material storage bin is fixedly mounted above the mounting frame, a first discharging funnel connected thereto is fixedly mounted at the lower end of the material storage bin, a first through slot is provided on the first discharging funnel, the first bin door is movably mounted in the first through slot, the first hydraulic cylinder is fixedly mounted on the right end of the mounting frame via a first support, a telescopic rod of the first hydraulic cylinder is fixedly connected to the first bin door, the metering bin is fixedly mounted in the mounting frame and is located below the material storage bin, an opening connected thereto is provided on the left side of the metering bin and on the top, a through slot connected to the opening is movably mounted on the left side of the metering bin The second hydraulic cylinder is fixedly mounted on the left side of the mounting frame, the telescopic rod of the second hydraulic cylinder is fixedly connected to the block, a pair of slide grooves are fixedly mounted on the front and rear wall plates of the metering bin, a bar grid is movably mounted in the slide groove, and the bar grid corresponds to the first discharging funnel, the third hydraulic cylinder is fixedly mounted on the right side of the mounting frame, the telescopic rod of the third hydraulic cylinder is fixedly connected to the bar grid, a second discharging funnel connected thereto is fixedly mounted at the lower end of the metering bin, a second through groove is provided on the second discharging funnel, and the second bin door is movably mounted in the second through groove, the fourth hydraulic cylinder is fixedly mounted on the right end of the mounting frame via a second support, and the telescopic rod of the fourth hydraulic cylinder is fixedly connected to the second bin door.

[0008] Preferably, the stopper is in a right-angled trapezoidal structure and extends upward out of the metering bin.

[0009] Preferably, the left end of the first compartment door is arranged as a beveled surface.

[0010] The beneficial effects that can be achieved by the utility model using the above technical solution are:

[0011] 1. An opening is opened on the left side of the metering bin to communicate with the top, and a block corresponding to the opening is movably installed on the left side of the metering bin. The block has a right-angled trapezoidal structure and extends upward out of the metering bin. Under the action of the second hydraulic cylinder, the block with the right-angled trapezoidal structure can adjust the capacity of the metering bin as required by the design, and it is more stable when used.

[0012] 2. A pair of slides are fixedly installed on the front and rear wall plates of the metering bin, and a bar grid is movably installed in the slide. The bar grid corresponds to the first discharge funnel. When the raw materials enter the metering bin from the storage bin, they need to pass through the bar grid. The bar grid moves left and right under the action of the third hydraulic cylinder. After the raw materials in the metering bin pile up and touch the bar grid, the bar grid will push them to both sides until the entire metering bin is filled. In this way, the raw materials of the entire metering hopper can be accurately obtained.

[0013] 3. By setting the left end of the first bin door to be an oblique surface, the storage bin can be closed better after the entire metering bin is filled. BRIEF DESCRIPTION OF THE DRAWINGS
