Problems solved by technology

The structural characteristics and working principle of the chain bucket sand dredger determine that there are three disadvantages: 1. When the sand bucket is dredging sand, the force is transmitted from the driving wheel to the underwater sand surface through the chain block, and the distance is long and the power loss is large; 2. The capacity of the sand bucket is small; 3. The chain block and the sand bucket are heavy, the speed is slow, and the production efficiency is low

Embodiment Construction

[0008] The description will be further expanded below in conjunction with the accompanying drawings. At first can find out the basic structure of a kind of dredging ship of the present invention from Fig. 1, Fig. 2. One large channel steel on the left and right sides of the conveyor frame 8 is used as the backbone, and two small channel steels are welded close to the large channel steel to increase the strength of the backbone and serve as a transport retaining wall. There are one group (two pieces) at the top and bottom of the conveyor frame Chain wheel, what the upper end is fixed on the hull 14 frame 13 is driving wheel 12, and the lower end is steering wheel 7. The chain 9 is a roller chain with accessories, on which a strip-shaped rigid panel 10 is laid to carry sand and stones, the chain is engaged between two sets of sprockets, and runs in the middle of the retaining wall 11, making the conveyor chain belt into a groove , has a large bearing space. The sand dredging b...

Abstract

The present invention is one kind of excavator and one kind of sand dredging boat, and relates to underwater sand excavation. The excavator is one sand dredging balance wheel with oscillating hydraulic cylinder to drive one balance wheel and the sand dredging board on the balance wheel to rotate reciprocally and periodically for cutting sand. The sand dredging boat includes one mechanical and hydraulic driving system and one conveying chain belt on the boat, and one sand dredging balance wheel in water. The present invention is superior to available chain-bucket sand dredging boat, and has separated excavating assembly and conveying assembly, hydraulic driving, 5-10 times raised production efficiency and easy control.

Description

technical field [0001] An excavator and a sand dredging ship of the present invention relate to underwater mining of sand and gravel, which is called "boat mining process" in the industry, and also called "water mining". Background technique [0002] "River Sand Mining and Management" book (the first edition in September 2006 of China Water Conservancy and Hydropower Press, edited by Wang Jinsheng, page 62 to page 65) has the following narrations to river channel sand mining and mechanical equipment. The author believes that river sandstone is the basic material that constitutes the river bed, and sand mining in the river can be used for dredging and filling foundations such as repairing embankments, improving river courses and waterways, intake and drainage outlets, soil borrowing for land reclamation, and operating sand for construction. Stone, panning metal or non-metallic substances and other purposes. According to whether the sand mining operation involves water, it ca...
