A bottom mud tillage device synchronous with the dredging cutter head

Abstract

The invention provides a bottom mud scratching and plowing device synchronous with a dredging knife head. The bottom mud scratching and plowing device comprises the dredging knife head and a dredging knife head cover, wherein the dredging knife head cover is in a cone frustum shape, plane cutting is conducted on the side face of the cone frustum shape, and the dredging knife head cover comprises a cover body barrel wall, a front bottom wall and a rear bottom wall; the dredging knife head stretches into the dredging knife head cover through a hole formed in the rear bottom wall and is arranged on the rear bottom wall; the two ends of the cut position of the cover body barrel wall are respectively provided with a tooth rake scratching and plowing component; each tooth rake scratching and plowing component comprises a vertical frame and a scratching and plowing tooth rake; the top end of each scratching and plowing tooth rake is sharpened, and the tail end of each scratching and plowing tooth rake is provided with a round head; each vertical frame is provided with a semicircular groove; the round head of each scratching and plowing tooth rake is arranged in the corresponding semi-circle groove; each vertical frame is fixedly arranged on the outer side of the cover body barrel wall. According to the bottom mud scratching and plowing device, by means of transverse swinging of the dredging knife head cover and due to the fact that friction positions of the scratching and plowing tooth rakes and bottom mud are different, the vertical and horizontal postures of the scratching and plowing tooth rakes are controlled, and synchronous scratching and plowing, with the consistent swinging direction and speed, of the scratching and plowing tooth rakes, the surface of the bottom mud, and the dredging knife head are achieved.

Description

technical field [0001] The invention belongs to the field of ecological environment protection technology and mechanical design, and relates to a bottom mud tillage device synchronized with a dredging cutter head. Background technique [0002] Sediment dredging is one of the most widely used engineering techniques to remove or remove sediment from water bodies. For those water bodies with polluted sediment, high sensitivity (such as drinking water source) or large depth, wet (i.e. with water) dredging technology is the first choice, and the dredging cutter heads that can be selected are mainly spiral and or round Disc type environmental protection reamer, and scraping suction head, etc. In addition to pursuing vertical high-precision dredging according to the design requirements, low dispersion of sediment, low residual mud volume, and surface smoothness are also the content of wet dredging for dredging tools and equipment (Li Jingui, Li Jinjun , Yang Jianhua, Ding Shuyou,...

AI Technical Summary

Problems solved by technology

Although people can still use other means to improve the suitability of dense sediment after dredging, since dredging is an underwater "concealed" project, it is invisible. The project for the purpose of loosening the underwater substrate will not only incur a large cost, but will also be very difficult to operate in practice
