The outer walls of the two feed hoppers are fixedly connected to corresponding fixing plates. Corresponding first motors are fixedly installed on the outer walls of the two fixing plates. Filter screens are installed on the inner walls of the two feed hoppers. First pull doors are machined on the surfaces of both feed hoppers. This utility model, through the arrangement of feed pipes, feed hoppers, fixing plates, first motors, elastic elements, rubber pads, filter screens, and first pull doors, allows for the filtering of concrete blocks.

Description

Technical Field

[0001] This utility model relates to the technical field of recycled concrete processing, and in particular to a recycled concrete sample batching device. Background Technology

[0002] Recycled concrete is made by crushing, washing, and grading waste concrete blocks, then mixing them in a certain proportion to form recycled aggregate, which partially or completely replaces natural aggregate in concrete formulations. The research and application of recycled concrete structures provides an important solution to the problem of waste concrete disposal resulting from the demolition of numerous dilapidated buildings. It also reduces the mining of natural sand and gravel, alleviating the pressure of increasingly scarce natural aggregates and mitigating the ecological damage caused by the excessive exploitation of natural resources. This is of great significance for promoting the resource utilization of construction waste and the sustainable development of the construction industry. Before production, recycled concrete requires sample batching.

[0003] An existing recycled concrete sample batching device (publication number CN220179727U) uses a scraper to move concrete blocks along the outer wall of a filter plate, thus screening the concrete blocks. The remaining blocks move to the hollow opening and enter the collection rack, facilitating the screening and collection of larger concrete blocks and reducing clogging inside the device. However, in this current concrete sample batching device, the scraper pushes concrete blocks into the gaps in the filter screen, clogging it. This prevents the concrete sample from falling through the filter, reducing the device's effectiveness. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a recycled concrete sample preparation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A recycled concrete sample batching device includes two feed pipes, the upper ends of which are fixedly connected to corresponding feed hoppers. The outer walls of the two feed hoppers are fixedly connected to corresponding fixing plates. The outer walls of the two fixing plates are respectively mounted with corresponding first motors. The output shafts of the two first motors are fixedly connected to corresponding elastic elements. The ends of the two elastic elements are respectively fixedly connected to corresponding rubber pads. The inner walls of the two feed hoppers are respectively equipped with filter screens. The surfaces of the two feed hoppers are each machined with a first sliding door.

[0007] Preferably, the lower ends of the two feed hoppers are respectively connected to the corresponding feed pipes.

[0008] Preferably, a second motor is installed at the end of each of the two feed pipes, and the output shafts of the two second motors are fixedly connected to the corresponding augers, and the size of the two augers matches the size of the corresponding feed pipe.

[0009] Preferably, the ends of both feed pipes are fixedly connected to the housing.

[0010] Preferably, the surface of the housing is machined with a second sliding door.

[0011] Preferably, the outer walls of the two rubber pads are respectively attached to the corresponding filter screens.

[0012] Preferably, the two filters are placed opposite each other to the corresponding first sliding door.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the set feed pipe, feed hopper, fixed plate, first motor, elastic element, rubber pad, filter screen and first pull door, when it is necessary to filter concrete blocks and batch concrete blocks of appropriate size, the external power supply of the first motor is connected and the first motor is started. The first motor drives the elastic element to rotate, the elastic element drives the rubber pad to rotate, and the rubber pad knocks on the filter screen to prevent large concrete blocks from clogging the mesh of the filter screen. This makes the mesh of the filter screen more unobstructed, thereby improving the working effect of the recycled concrete sample batching device.

[0015] 2. With the second motor, feed pipe and auger set up, when qualified concrete blocks enter the feed pipe, the external power supply of the second motor is turned on and the second motor is started. The second motor drives the auger to rotate and the auger sends the concrete blocks into the box. In the above way, the auger can send concrete blocks of various shapes into the box for batching, so that powdery or granular concrete blocks can be transported into the box. This reduces the working limitations of the recycled concrete sample batching device. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A recycled concrete sample batching device includes two feed pipes 2, the upper ends of which are fixedly connected to corresponding feed hoppers 6. The feed hoppers 6 are fixed on the feed pipes 2. The outer walls of the two feed hoppers 6 are fixedly connected to corresponding fixing plates 7. The outer walls of the two fixing plates 7 are respectively fixedly connected to corresponding first motors 8. The model of the first motors 8 is selected according to actual needs and can meet the working requirements. The output shafts of the two first motors 8 are fixedly connected to corresponding elastic elements 9. The first motors 8 drive the elastic elements 9 to rotate. The elastic elements 9 are metal springs. The ends of the two elastic elements 9 are respectively fixedly connected to corresponding rubber pads 10. The elastic elements 9 drive the rubber pads 10 to rotate. The inner walls of the two feed hoppers 6 are respectively equipped with filter screens 11. The surfaces of the two feed hoppers 6 are all machined with first sliding doors 12. When it is necessary to filter concrete blocks and mix appropriately sized concrete blocks, the external power supply of the first motor 8 is connected, and the first motor 8 is started. The first motor 8 drives the elastic element 9 to rotate. The elastic element 9 prevents the rubber pad 10 from making hard impacts on the filter screen 11. The elastic element 9 drives the rubber pad 10 to rotate, and the rubber pad 10 knocks on the filter screen 11, preventing large concrete blocks from clogging the mesh of the filter screen 11. This makes the mesh of the filter screen 11 more unobstructed, thereby improving the working effect of the recycled concrete sample mixing device.

[0024] In this embodiment, the lower ends of the two feed hoppers 6 are respectively connected to the corresponding feed pipes 2. The ends of the two feed pipes 2 are respectively equipped with second motors 3. The model of the second motors 3 is selected according to actual needs, and only those that meet the working requirements are selected. The output shafts of the two second motors 3 are respectively fixedly connected to the corresponding augers 4. The second motors 3 drive the augers 4 to rotate. The size of the two augers 4 matches the size of the corresponding feed pipes 2. The ends of the two feed pipes 2 are fixedly connected to the box body 1. The feed pipes 2 can feed concrete blocks into the box body 1. The surface of the box body 1 is processed with a second sliding door 5. The second sliding door 5 is closed when not in operation. The outer walls of the two rubber pads 10 are respectively attached to the corresponding filter screens 11. The rubber pads 10 tap the filter screens 11 to prevent the filter screens 11 from clogging. The two filter screens 11 are placed corresponding to the first sliding door 12 so that the concrete blocks above the filter screens 11 can be taken out from the first sliding door 12.

[0025] The working principle of this embodiment is as follows: In use, the operator first opens the second sliding door 5, then pours concrete blocks into the feed hopper 6. Next, the external power supply to the two first motors 8 is connected, and the first motors 8 are started. The first motors 8 drive the elastic element 9 to rotate, which in turn drives the rubber pad 10 to rotate. The rubber pad 10 strikes the filter screen 11, preventing the mesh of the filter screen 11 from being blocked by larger concrete blocks. Concrete blocks of the correct size fall into the feed pipe 2. After the correct-sized concrete blocks enter the feed pipe 2, the external power supply to the two second motors 3 is connected... Connect the power supply and start the two second motors 3. The second motors 3 drive the auger 4 to rotate. The auger 4 feeds the concrete blocks into the box 1. After all the concrete blocks have been conveyed, the batching is completed in the box 1. The batched recycled concrete is then sent out of the box 1 through the second sliding door 5. The second motors 3 are turned off. After use, the second sliding door 5 is closed, and the two first motors 8 are turned off. Then, the operator opens the first sliding door 12 and cleans the larger concrete blocks above the filter screen 11 out of the feed hopper 6. After that, the first sliding door 12 is closed, and the batching of the recycled concrete sample is completed.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
