[0002] Concrete is one of the main civil engineering materials in contemporary times. It is a man-made material prepared by cementitious materials, aggregate water reducers and water in a certain proportion, stirred and tamped into shape, and cured under certain conditions. It has the characteristics of rich raw materials, low price and simple production process, so its usage is increasing. The water reducer for concrete is a concrete admixture that can reduce the mixing water consumption under the condition of maintaining the basic unchanged slump of the concrete. Most of them belong to anionic surfactants, such as lignosulfonates, naphthalene sulfonate formaldehyde polymers, etc.

An electric door is arranged inside the connecting pipe 3, and the opening and closing of the electric door can be controlled by a computer. The connecting pipe 3 is a flexible pipe; it also includes;

[0030] Cleaning mechanism, arranged at the top of the fixed frame 2, used to scrape and wash the storage place of the water reducing agent. The top of the connecting pipe 3 is clamped with the bottom of the cleaning mechanism, and the connecting pipe 3 can be disassembled at any time. The cleaning mechanism includes a scraping component, a water washing component, a positioning component and an installation component; the scraping component is arranged at the top of the fixed frame 2, used to scrape the remaining water reducing agent on the inner wall of the water reducing agent storage place; the water washing component is arranged on the top of the scraping component, used to wash the inner wall of the water reducing agent storage place; the installation component is arranged inside the scraping component, used to control the switch of the positioning component to close or open the mechanism.

When closed, it is used to normally add concrete; the positioning component is arranged outside the scraping component, used to fix the opening and closing states of the positioning component. The scraping component includes a storage barrel 401, a chute 425, a scraping ring 413, a pull ring 414, a slide rail 415 and a stop bar 416; the storage barrel 401 is arranged at the top of the fixed frame 2, the chute 425 is located on the inner wall of the storage barrel 401, the stop bar 416 is slidably arranged inside the chute 425, the scraping ring 413 is arranged on the side of the stop bar 416, the pull ring 414 is arranged on the side of the stop bar 416 away from the scraping ring 413, the slide rail 415 is arranged outside the storage barrel 401, and the pull ring 414 is slidably arranged on the slide rail 415. The shape of the stop bar 416 is exactly the same as the shape of the chute 425. Therefore, when the pull ring 414 drives the stop bar 416 to move, the stop bar 416 can fill all the vacancies of the chute 425, preventing the concrete water reducing agent from falling into the chute 425 and causing difficult cleaning. At the same time, when the stop bar 416 moves, it can drive the scraping ring 413 to move. Both sides of the scraping ring 413 are inclined planes, so the water reducing agent on the inner wall of the storage barrel 401 can be scraped and cleaned both upward and downward, and the cleaning effect is better. The water washing component includes a water tank 402, a motor 403, a water delivery pipe 404, a water inlet 406 and a spray head 405; the water tank 402 is arranged on the top of the storage barrel 401, the motor 403 is arranged on the top of the water tank 402, the water delivery pipe 404 is arranged at the output end of the motor 403, the water inlet 406 is located on the water delivery pipe 404, the spray head 405 is arranged at the end of the water delivery pipe 404 away from the motor 403. The water in the water tank 402 enters the water delivery pipe 404 through the water inlet 406, and then the water sprays out from the spray head 405. At the same time, the motor 403 can drive the water delivery pipe 404 to rotate, the water delivery pipe 404 drives the spray head 405 to rotate, and the spray head 405 rotates and sprays water to comprehensively wash the inner wall of the storage barrel 401.The positioning component includes a connecting shaft 407, a positioning hole 409, a swivel ring 408, a plug rod 410, a fixing plate 411, and a first spring 412; the connecting shaft 407 is arranged on the side of the connecting piece 420 away from the second spring 423, the positioning hole 409 is located at one end of the connecting shaft 407 away from the connecting piece 420, the swivel ring 408 is arranged at one end of the connecting shaft 407 away from the connecting piece 420, the fixing plate 411 is arranged on the outside of the storage barrel 401, the plug rod 410 is slidably arranged inside the fixing plate 411, the first spring 412 is located outside the plug rod 410, and the end of the plug rod 410 can be clamped in the positioning hole 409. There are two positioning holes 409. The positioning hole 409 near the end is used to fixedly install the component, and the positioning hole 409 away from the end is used to rotate the installation component in Embodiment 2.

[0031] As Figure 5 shown, a concrete water reducer feeding device proposed by the present utility model, compared with Embodiment 1, this embodiment details the structure of the installation component.

[0032] The installation component includes a chassis 417, a slot 419, a connecting piece 420, a second spring 423, a fixing block 424, a rotating rod 421, a discharge port 418, and a moving rod 422; the chassis 417 is rotatably arranged at the bottom of the storage barrel 401, the slot 419 is located at the bottom of the inner wall of the storage barrel 401, the fixing block 424 is arranged on the inner wall of the chassis 417, the second spring 423 is arranged on the side of the fixing block 424, the connecting piece 420 is arranged at one end of the second spring 423 away from the fixing block 424, the rotating rod 421 is rotatably arranged on the side of the connecting piece 420, the moving rod 422 is rotatably arranged at one end of the rotating rod 421 away from the connecting piece 420. There are two rotating rods 421. When the connecting piece 420 moves, the moving rod 422 can be driven to move through the rotating rod 421. The moving rod 422 slides in the slot 419. When the moving rod 422 moves to the end of the slot 419, the chassis 417 can be fixed. When the moving rod 422 is away from the end of the slot 419, the chassis 417 can be released to rotate, and when rotating, the water reducer scraped by the scraping component and the water washing component can be discharged from the storage barrel 401.

[0033] In summary, when the utility model is in use, disconnect the connecting pipe 3 and the storage barrel 401. At this time, the moving rod 422 is stuck at the end of the slot 419, and the chassis 417 is in a closed state. Fix this state by inserting the insertion rod 410 into the positioning hole 409 near the end. Then, pull the pull ring 414 to slide on the slide rail 415. The pull ring 414 drives the blocking rod 416 to move in the chute 425. When the blocking rod 416 moves, it can drive the scraping ring 413 to move. Both sides of the scraping ring 413 are inclined planes, so the water reducing agent on the inner wall of the storage barrel 401 can be scraped and cleaned both upward and downward. At the same time, start the motor 403. The motor 403 drives the water delivery pipe 404 to rotate, and the water delivery pipe 404 drives the nozzle 405 to rotate. Since the nozzle 405 points to the inner wall of the storage barrel 401, it can be comprehensively rinsed during rotation. After the water reducing agent is cleaned, pull out the insertion rod 410 from the positioning hole 409. The connecting shaft 407 moves outward under the action of the second spring 423. When moving, it drives the two moving rods 422 to move towards each other through the rotating rod 421, so as to disengage from the slot 419, enabling the chassis 417 to rotate. After rotating the chassis 417, the scraped water reducing agent can be taken out to keep the inside of the storage barrel 401 clean and tidy.

[0034] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited thereto. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
