[0019] Combined with appendix Figures 1-3 The intelligent construction self-cleaning concrete feeding device includes a hopper 1, a conveying mechanism, a control mechanism, and a self-cleaning mechanism.

[0020] The hopper 1 has a discharge port on its bottom surface; the conveying mechanism includes a conveying pipe 13 connected to the discharge port of the hopper 1, and a screw feeder 2 connected to the conveying pipe 13; the control mechanism includes a PLC controller 8 mounted on the support of the hopper 1, a material level sensor 10 mounted on the inner wall of the hopper 1, and a flow sensor 12 mounted at the outlet of the screw feeder 2. The PLC controller 8 is electrically connected to the screw feeder 2, the material level sensor 10, and the flow sensor 12, respectively; the self-cleaning mechanism includes a recycling box 7 connected to the conveying pipe 13. A water pump 9 is provided on the side wall of the recycling box 7, and the input end of the water pump 9 is connected to the inner cavity pipeline of the recycling box 7. The output end of the water pump 9 is connected to a water spray pipe 14 arranged on the inner wall of the hopper 1 through a pipeline, and the water spray pipe 14 is provided with several nozzles 6.

[0021] In one embodiment of this utility model, the conveying pipe 13 is a three-way pipe, one end of which is connected to the hopper 1, and the other two ends are respectively provided with a first gate valve 3 and a second gate valve 4 electrically connected to the PLC controller. Specifically, as shown... Figures 1-2 As shown, the three ports of the three-way pipe are the feed end, the first discharge end, and the second discharge end. The feed end is sealed to the discharge port of the hopper 1. The first gate valve 3 is installed on the pipe of the first discharge end, and the second gate valve 4 is installed on the pipe of the second discharge end. Both are electric gate valves, and their opening and closing status is controlled in real time by the PLC controller. When concrete needs to be conveyed, the PLC controller controls the first gate valve 3 to open and the second gate valve 4 to close. The screw feeder 2 operates to convey the concrete to the target position through the opened gate valve. When performing self-cleaning operation, the PLC controller controls the first gate valve 3 to close and the second gate valve 4 to open, so that the cleaning wastewater in the hopper 1 flows to the recycling box 7 through the conveying pipe 13, avoiding pollution caused by wastewater.

[0022] In one embodiment of this utility model, the recycling bin 7 is equipped with a filter screen, and the pipeline connected to the water pump 9 is connected to the inner cavity of the recycling bin 7 below the filter screen. Specifically, the filter screen is horizontally arranged in the upper middle part of the inner cavity of the recycling bin 7, dividing the inside of the recycling bin 7 into upper and lower cavities. The upper cavity is used to receive cleaning wastewater and concrete residue flowing in from the conveying pipe 13, and the lower cavity is used to collect filtered water. The filter screen is made of stainless steel with a mesh diameter of 2-5mm, which can effectively intercept concrete residue and ensure smooth water flow. The inlet end of the pipeline connected to the water pump 9 is located at the bottom of the lower cavity, ensuring that the water pump 9 draws water that has been fully filtered by the filter screen, avoiding residue from entering the water pump 9 and causing equipment damage, while improving the cleanliness of the cleaning water and ensuring the cleaning effect of the hopper 1.

[0023] In one embodiment of this utility model, a drain pipe with a switch valve is provided on the side wall of the recycling bin 7, and a cleaning port is opened on the top surface of the recycling bin 7 and a cover plate 5 is rotatably connected to cover the cleaning port. Specifically, as shown... Figures 1-2 As shown, the drain pipe is located on the lower part of the side wall of the recycling bin 7, near the bottom of the recycling bin 7. The switch valve installed at its end is a manual ball valve. When too much unfilterable fine sediment accumulates in the recycling bin 7 or when the cleaning water needs to be replaced, the switch valve can be opened to drain the water and sediment from the bin. The cleaning port is located on the top surface of the recycling bin 7. The cover plate 5 is rotatably connected to the top surface of the recycling bin 7 via a hinge. The edge of the cover plate 5 is equipped with a sealing strip to prevent debris from falling into the recycling bin 7 when closed. When it is necessary to clean the concrete residue intercepted on the filter screen, the cover plate 5 can be opened to directly clean or replace the filter screen. The operation is convenient and does not require disassembling the entire structure of the recycling bin 7.

[0024] In summary, this utility model achieves intelligent and automated concrete feeding by rationally arranging the hopper 1, conveying mechanism, control mechanism, and self-cleaning mechanism. The control mechanism integrates various sensor data through a PLC controller to precisely regulate the conveying process. The three-way pipe design of the conveying mechanism, combined with the gate valve, flexibly adapts to different working scenarios. The self-cleaning mechanism, with the help of the recycling box 7, filter screen, and circulating water pump 9, realizes automatic cleaning of the hopper 1 and water resource recycling. At the same time, the maintenance process is simplified through the cleaning port and drainage pipe. The overall device effectively solves the problems of low automation and difficult cleaning of traditional feeding equipment.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
