Description

Technical Field

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

[0002] Recycled concrete refers to the new concrete made by crushing, cleaning, grading, mixing with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregate), and then adding cement, water, etc. According to the combination of aggregates, recycled concrete can have the following situations: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates and fine aggregates are natural sand; coarse aggregates are natural crushed stone or pebbles and fine aggregates are recycled aggregates; recycled aggregates replace part of coarse aggregates or fine aggregates. When producing and processing recycled concrete, it is necessary to crush the discarded concrete before mixing the ingredients.

[0003] The patent document with application number CN220179727U discloses a recycled concrete sample batching device, which relates to the field of concrete batching technology, improves the problem that the large discarded concrete blocks after crushing are difficult to filter and cause blockage inside the batching device, and includes a support frame, the top of the support frame is fixedly connected with a protective plate, the top of the protective plate is fixedly connected with a motor frame, the inside of the motor frame is fixedly connected with a driving motor, the output end of the driving motor is fixedly connected with a connecting rod through a linkage shaft, the outer wall of the connecting rod is fixedly connected with a fixed block, the outer wall of the fixed block is fixedly connected with an extension frame, and the bottom end of the extension frame is fixedly connected with a scraper. The recycled concrete sample batching device drives the concrete blocks to move on the outer wall of the filter plate through the scraper, so that the concrete blocks are screened through the filter plate. When the remaining soil blocks are moved to the hollow port and enter the inside of the collection frame, the screening and collection of larger concrete blocks are facilitated, and the blockage of the device by larger soil blocks is reduced.

[0004] In the above-mentioned related technologies, when the device fails, the bottom of the mixing frame can be blocked to suspend the transportation of raw materials. However, when mixing the crushed waste concrete and cement and other materials, a certain proportion is required, and the raw materials to be transported cannot be calculated, which makes the operation inconvenient. In view of the above problems, we have launched a recycled concrete sample batching device. Utility Model Content

[0005] The utility model discloses a recycled concrete sample batching device, which aims to solve the technical problem in the above-mentioned related technology that when the device fails, the bottom of the mixing frame can be blocked to suspend the conveying of raw materials, but when the crushed waste concrete and cement and other materials are mixed, a certain proportion is required, and the conveyed raw materials cannot be calculated, resulting in inconvenient operation.

[0006] To achieve the above object, the utility model provides the following technical solution: A batching device for recycled concrete specimens, comprising a filtration box, a filtration component and a material distribution component. Columns are fixedly arranged around the outer side of the filtration box. A material distribution box is fixedly installed below the filtration box through a cross bar in the middle of the columns. A fixed box is fixedly installed on one side of the columns through a fixing plate. The filtration box and the fixed box are communicated through a first connecting pipe.

[0007] Through the arranged material distribution component, the crushed waste concrete after being filtered by the filtration component enters the material distribution groove inside the material distribution box through the second connecting pipe. The material distribution groove is equally divided into four equal parts by the material distribution plates on the outer side of the second rotating rod. The rotation of the output end of the second motor drives the second rotating rod to rotate. Further, the waste concrete on the side of the material distribution groove close to the material receiving groove is brought above the outlet groove by two adjacent material distribution plates and falls into the material receiving box below through the outlet groove. The rotation times of the second motor can be adjusted according to the actual demand for waste concrete.

[0018] In a preferred embodiment, a discharge pipe is fixedly installed through the bottom of the fixed box, and the bottom wall inside the filter box and close to the second connecting pipe is set as an inclined surface.

[0019] By setting up the discharge pipe, it is beneficial to export the large pieces of waste concrete inside the fixed box for re-crushing. Setting the bottom wall of the filter box close to the second connecting pipe as an inclined surface facilitates the filtered waste concrete inside the filter box to enter the second connecting pipe.

[0020] The present utility model has the following beneficial effects:

[0021] Through the material distribution component set in the present utility model, the crushed waste concrete after being filtered by the filtering component enters the material distribution groove inside the material distribution box through the second connecting pipe. The material distribution groove is equally divided into four equal parts by the material distribution plates on the outer side of the second rotating rod.
