Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical equipment technical field, concretely is a cement paste spreading device. BACKGROUND

[0002] In the construction, cement paste spreading is a common operation process, especially in concrete hardening, pavement pouring and foundation construction. The traditional cement paste spreading operation relies on manual operation, which has low mixing efficiency, high labor intensity and is difficult to control construction quality. In addition, due to the difference in viscosity of cement paste, the bottom and upper paste often cannot be uniformly mixed, resulting in unstable construction quality. Especially in mass concrete construction, the over-thick bottom paste and the proportion imbalance of the upper thin paste affect the overall strength and durability of the concrete, and even cause cracks and uneven quality problems. Therefore, in order to improve construction efficiency, reduce labor intensity and ensure the stability of construction quality, an automatic, efficient and uniform mixing device for cement paste is urgently needed.

[0003] At present, the common cement paste mixing equipment has many deficiencies. First, manual operation has low efficiency and high labor intensity, and the uniform mixing of paste cannot be effectively ensured during construction, which makes the bottom paste too thick and the upper paste too thin, affecting the subsequent construction quality. Secondly, due to the easy deposition of cement paste during mixing, the effective utilization rate of the bottom paste is reduced, resulting in a lot of waste. In addition, due to the small space of the construction site, manual mixing cannot efficiently cover the entire water tank, especially the bottom deposited paste cannot be fully scraped, further affecting the mixing effect. Therefore, an automatic mixing device is urgently needed to realize uniform mixing of bottom and upper paste, reduce dependence on manual operation, improve construction efficiency and quality stability.

[0004] The traditional mixing equipment has a simple structure and mainly uses stirring paddle mixing method. This method can meet the demand in small-scale construction, but in large-scale construction, due to the difference in viscosity of paste, the mixing effect is difficult to keep uniform. Especially in large construction sites, the bottom paste is too thick and the upper paste is too thin, which directly affects the construction quality and later use effect. In addition, the traditional equipment cannot effectively solve the problem of recycling the paste deposited at the bottom of the water tank, resulting in a lot of material waste and affecting economic benefits. Therefore, in order to improve construction efficiency, enhance mixing effect and recycling of cement paste, an advanced cement paste spreading device is urgently needed. SUMMARY

The driven gear 431 is rotatably installed on the base 426 and in mesh transmission with the driving gear 432. The gear ring 433 is fixed on the inner wall of the sleeve pipe 424 and in mesh transmission with the driven gear 431. The lower end of the stirring pipe 427 is fixedly connected with the sleeve pipe 424. The stirring pipe 427 is externally fixedly provided with a stirring rod 423. The stirring rod 421 is fixedly provided with a helical stirring blade 422. The driving motor 41 drives the stirring rod 421 to rotate. Through the cooperation of the driving gear 432, the driven gear 431 and the gear ring 433, the sleeve pipe 424 drives the stirring pipe 427 to rotate. The rotating speed of the stirring pipe 427 is less than the rotating speed of the stirring rod 421. Thus, the cement paste in the lower half of the water tank 5 is stirred by the stirring rod 423 on the stirring pipe 427. The cement paste in the upper half of the water tank 5 is stirred by the helical stirring blade 422 and is pushed downward, so that the cement paste in the water tank 5 is circulated and stirred.

[0026] Further, the outer portion of the sleeve pipe 424 is provided with a water retaining ring 428. The upper end of the water retaining ring 428 is fixedly connected with the sleeve pipe 424. The lower end of the water retaining ring 428 extends from the top end of the base 426 to the outer portion of the base 426. A sealing ring 429 is arranged between the base 426 and the water retaining ring 428. A plurality of scrapers 425 are installed on the outer portion of the water retaining ring 428. The plurality of scrapers 425 are distributed in a circumferential array with the axis of the stirring rod 421 as the center. The scrapers 425 are obliquely arranged. One end of each scraper 425 is fixedly connected with the water retaining ring 428. The lower end surface of each scraper 425 is in abutment with the inner bottom surface of the water tank 5. Thus, the cement paste deposited on the bottom of the water tank 5 is scraped up by the scrapers 425, so that the stirring effect is improved.
