Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Abstract

The invention discloses an anti-winding dredging reamer comprising a wheel hub, a base ring and tool arms; the axis of the wheel hub is a first axis; the base ring and the wheel hub are arranged alongthe first axis at intervals, and the axis of the base ring is also the first axis; one end of each tool arm is fixedly connected with the wheel hub, and the other end of each tool arm is fixedly connected with the base ring; and the outer side of each tool arm is a continuous first cutting edge. According to the anti-winding dredging reamer, the continuous first cutting edge is formed on each tool arm; during construction, the reamer is placed to a mud layer firstly; when the reamer is placed to the specified position, the mud layer is cut and stirred by the first cutting edges on the tool arms through rotation of the reamer; in the cutting and stirring process, since the first cutting edge is continuously linear, the situation that steel bars and other sundries are hooked and consequently the reamer is wound can be avoided.

Description

technical field [0001] The invention relates to the technical field of dredging engineering, in particular to an anti-winding dredging reamer. Background technique [0002] At present, in the dredging industry, reamers are mainly used for the excavation and dredging of underwater soil, and various geological conditions will be encountered during dredging operations. [0003] Most of the existing reamers are toothed reamers with cutter teeth. Under special working conditions where there is a large amount of garbage in the mud layer, a large amount of garbage in the mud layer will be entangled on the blade, causing the reamer head to be stuck, unable to rotate, stop the operation, and seriously affect the efficiency of dredging construction. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide an anti-winding dredging reamer, which uses continuous linear blades to replace traditional d...
