Impact-resistant dredger hopper gate plate

Abstract

The invention provides an impact-resistant dredger hopper gate plate. The impact-resistant dredger hopper gate plate comprises a cover body and a sealing piece arranged on the inner side of the coverbody, wherein the sealing piece comprises a cushion body portion and a sealing ring portion which is located on the end surface of the side, far away from the cover body, of the cushion body portion,the cover body comprises a base plate and an outer surface plate, a gap between the base plate and the outer surface plate is divided into a plurality of independent cavities through supporting frames, heat preservation cotton fills each cavity, each supporting frame is made of elastic materials, each supporting frame is wholly of a corrugated plate-shaped structure, and comprises a buffer portionwith a bent middle portion and a connecting portion with two straight ends. According to the impact-resistant dredger hopper gate plate, the structural design is reasonable, when impacting is born, the buffer portions can effectively play a role in buffering and damping, and can further play a role in supporting to the certain degree at the same time, then the stability of the relative structureof the outer surface plate and the base plate is guaranteed, the heat preservation cotton fills all the cavities formed among all the supporting frames, then the heat preservation effect is achieved,meanwhile, the mute effect is further achieved, the stability of the quality of the raw materials is guaranteed to the maximum extent, and meanwhile, the noise is low.

Description

technical field [0001] The invention belongs to the technical field of offshore dredger equipment, and in particular relates to an impact-resistant dredger hopper ram. Background technique [0002] Cutter suction dredger is a kind of ship widely used in beach dredging projects. It uses the front end of the suction pipe to install a rotary reamer device around the suction pipe to cut and stir the river bottom sediment, and then through suction dredging The pipe transports the twisted sediment material to the sediment material accumulation field with the help of a powerful pump force. Its dredging, mud transportation, mud unloading and other working processes can be completed continuously at one time. It is a high-efficiency, low-cost The lower dredger is a good underwater excavating machine. However, there are deficiencies in the design of the ram structure of the mixing hopper on the existing dredger, and it is relatively easy to be damaged prematurely due to the friction o...

AI Technical Summary

Problems solved by technology

However, there are deficiencies in the design of the ram structure of the mixing hopper on the existing dredger, and it is relatively easy to be damaged prematurely due to the friction of mud and sand, and often the seal is not tight, or even completely fails, which brings great inconvenience to the mixing of raw materials , it is difficult to ensure a better ratio. When a leak occurs, the ratio of raw materials needs to be re-proportioned, which increases the time for adjusting the ratio of raw materials and stirring, which is time-consuming and laborious.
