Description

Technical field:

[0001] The invention relates to the technical field of concrete waste material processing, and more specifically to an external transfer device for concrete waste material. Background technology:

[0002] With the development of real estate and infrastructure projects, the demand for concrete is also increasing. When the wet-mixed concrete in the concrete mixer pump truck is not used up, there will be waste of residual materials or random throwing, resulting in waste of resources and random stacking. In order to avoid the above problems, it is necessary to deal with the residual concrete. At present, there are several ways to deal with the residual concrete: 1. Using concrete for landfill. Using the remaining concrete for landfill is a common treatment method. First, the concrete needs to be chopped and then sprinkled into the landfill and mixed with other garbage for landfill. However, this method has high requirements for the landfill and needs to ensure the stability and safety of the landfill; 2. Using concrete for recycling, the remaining concrete can also be recycled, such as for making pavements, sidewalks, walls, etc. In the process of recycling, the concrete needs to be reprocessed to ensure that its quality meets the requirements. This method can effectively save resources and reduce waste; 3. Using concrete for waste production, the remaining concrete can also be used to make waste products, such as flower pots, small tables, stone flower beds, etc. This method can not only play an environmental role, but also create some useful items and achieve resource recycling; 4. Clean and reuse. If the concrete is not completely dry, it can be rinsed with water and reused. This method can reduce concrete waste and reduce construction costs.

[0003] The first three of the above methods require the rapid disposal of the remaining concrete, and the fourth method can be used for a long time. Therefore, for the fourth method, a silo can be used to store the remaining concrete after cleaning, but the remaining concrete needs to be rinsed before storage, so it is necessary to design a set of processing equipment before concrete storage.

[0034] Working principle: This structure is an external transfer device for concrete residues. Its structure is as follows: Figure 1 , 2 As shown, the transfer device is provided with two transfer buckets, which are respectively a transfer load-bearing bucket 3 and a material receiving and flushing bucket 7. The transfer load-bearing bucket 3 is used for weighing, and the material receiving and flushing bucket 7 is used for flushing the residual concrete. The specific processing process is as follows:

[0035] The concrete mixer truck transports the concrete residue to the transfer carrying bucket 3 located at a high position of the support frame 5, wherein the transfer carrying bucket 3 is located in a position that matches the concrete mixer truck; then the weighing sensor 43 on the weighing mechanism 4 is used to detect the weight of the concrete residue in the transfer carrying bucket 3, and then the total weight of the concrete residue stored in the silo can be obtained to proportion the amount of cement and additives added later;

[0036] After weighing is completed, the transfer carrying bucket 3 is moved downward by the lifting mechanism 6, and then the electromagnetic butterfly valve on the transfer carrying bucket 3 is opened, and then the water channel on the flushing mechanism 8 is opened, so that the flushing nozzle 82 sprays a flushing water jet, and the inner wall of the transfer carrying bucket 3 is first flushed by the flushing water jet, and the remaining concrete in the transfer carrying bucket 3 is all dropped into the receiving flushing bucket 7;

[0037] Then the lifting mechanism 6 is started to move the transfer carrying bucket 3 upward, and then the flushing nozzle 82 flushes the concrete residue in the receiving material flushing bucket 7, and the cement in the concrete residue flows out of the filter hole 71 of the receiving material flushing bucket 7 with the water flow. The purpose of flushing is to cause the cement in the concrete residue to solidify and become scrapped, and then flush and drain;

[0038] After the drainage is completed, the traction and flipping mechanism 9 is started, and the traction conveyor belt 91 on the traction and flipping mechanism 9 drives the material receiving and flushing bucket 7 to move toward the silo on the conveying track 10, so that the material receiving and flushing bucket 7 enters the silo, and then the slider 99 on the traction and flipping mechanism 9 abuts against the limit block 11, but the traction conveyor belt 91 continues to move, and then the guide support shaft 96 moves in the guide groove 951 of the connecting plate 95, driving the guide support shaft 96 to push the material receiving and flushing bucket 7, and then the material receiving and flushing bucket 7 is flipped backward around the hinge shaft 98, and the remaining material in the material receiving and flushing bucket 7 is dumped into the silo.
