Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and particularly relates to a concrete grouting device. Background Art

[0002] Concrete grouting is to inject specific grouting materials into cracks, pores or loose parts of concrete structures to improve the compactness, strength and durability of concrete. The principle is to utilize the fluidity and cementitiousness of the grouting materials to fill the defects in the concrete, so that the structure can restore its integrity and stability.

[0003] A concrete grouting device of Chinese utility model patent (CN221142790U) drives an annular scraper to move through a hydraulic cylinder and a cover plate, scrapes the residual concrete on the inner wall of the material box through the annular scraper, and drives a movable strip to scrape the concrete on the annular scraper through a motor, a main shaft, a limiting strip and a sleeve, so that the residual concrete drops for use, thereby reducing the residual curing of concrete on the inner wall of the material box and the waste of concrete during the grouting process, facilitating the cleaning of the whole device by a spraying unit after the grouting is completed, and effectively improving the convenience and efficiency of cleaning the device.

[0004] In this patent, the motor drives the stirring plate to rotate and stir the concrete through the main shaft. At the same time, a hydraulic cylinder is set to drive the annular scraper to scrape the concrete attached to the inner wall of the material box through the cover plate. The correlation between the scraping structure and the stirring structure is relatively low. Although they can be carried out synchronously, two power sources, namely a hydraulic cylinder and a motor, need to be set. And due to the limitation of its scraping structure, the stirring plate can only stir at the bottom of the material box, and the stirring effect is not good. Therefore, there is room for improvement in the technical solution of this patent. Content of the Utility Model
