Problems solved by technology

[0003] Environmental protection reamers are generally equipped with a protective cover, but currently the protective cover outside the environmental protection reamer head can only cover the environmental protection reamer, and the protection range is small; at the same time, due to the uneven bottom mud of rivers and lakes, the protective cover The shell cannot fit well with the mud surface, causing part of the clear water in the upper lake to enter the mud cavity and mix with the dredged soil, resulting in a high moisture content of the sucked dredged mud, which requires re-treatment of tail water, increasing construction costs and long construction period

Embodiment 1

[0033] Example 1: Please also see Figure 1 to Figure 5 , the present embodiment provides an environmentally friendly cutter head, which is installed on a dredger and used for cleaning underwater polluted sediments such as rivers and lakes. Specifically, the environmentally friendly reamer head includes a reamer 1, and the reamer 1 is provided with a protective case 2, and a steel plate 21 is welded to the lower edge of both sides of the protective case 2 and the stiffener at the front end. The joints of the steel plates 21 are welded to each other, and the added steel plate 21 increases the protective area of ​​the protective cover 2, which effectively prevents some clear water from the upper lake from entering the mud cavity and mixing with the dredged soil. Under the action of negative pressure, the sucked bottom The amount of mud increases and the amount of water decreases, thereby forming mud with a high water content, which effectively increases the solid content of the ...

Embodiment 2

[0041] Example 2: Please also see Figure 1 to Figure 9 , the present embodiment provides a kind of environmental protection reamer head, and its difference with embodiment 1 only lies in:

[0042] The environmental protection reamer head also includes a cleaning mechanism, which is used to clean the reamer 1 and the protective cover 2; the said nozzles 8 are arranged on the flange 4, and the Spray nozzle 8 is arranged between described annular knife seat 15 and described protective cover 2, and it connects water pump through water pipe 81; Mud is cleaned, and the reamer 1 does not need to be disassembled to clean the reamer 1, which is more convenient.

[0043] working principle:

[0044] Before use, the environmental protection cutter head is installed on the dredger, and the connecting flange 35 is connected to the mechanical arm on the dredger; the protective cover 2 is placed outside the cutter 1, and fixed to the flange 4 by bolts and nuts .

Abstract

The invention relates to the technical field of desilting reamers, and discloses an environment-friendly reamer head. The environment-friendly reamer head comprises a reamer, the reamer is externallyprovided with a protective shell, steel plates are welded to stiffening ribs of the lower edges of the two sides and the front end of the protective shell correspondingly, and the steel plates are connected through mutual welding; the environment-friendly reamer head is provided with a horizontal adjustment device which is used for adjusting the angle of the reamer; through the protective shell ofthe environment-friendly reamer head, part of upper layer clear water in a lake is effectively stopped from entering a slurry cavity and being mixed with dredged soil, under action of negative pressure, the amount of sucked bottom sludge is increased, the amount of water is decreased, accordingly, slurry high in water content is formed, and the solid content of the slurry is effectively increased.

Description

technical field [0001] The invention relates to the technical field of dredging reamers, in particular to an environmental protection reamer head. Background technique [0002] Environmental protection dredging has become an important content in river course and lake treatment projects. In recent years, cutter suction dredgers have been widely used in domestic river and lake environmental protection dredging. Cutter suction dredgers mainly use spiral reamers or environmental protection reamers. The spiral reamers are open reamers with fast stirring speed, but when they are used, the water body is disturbed in a large range, and the sludge is easy to spread. The cutter suction dredger equipped with an environmentally friendly cutter head has a high output. The environmentally friendly reamer is used to clean up underwater polluted sediments such as rivers and lakes, and is a new type of reamer that has the least disturbance to the surroundings. [0003] Environmental protec...
