Abstract

The utility model relates to an annular cylindrical mud-feeding shovel. The mud-feeding shovel comprises an annular cylinder, a grid plate and a mud-feeding pipe, wherein the mud-feeding pipe is communicated with pneumatic dredge pumps; the mud-feeding pipe, a mud-discharging pipe and an air inlet and output pipe are designed on each pneumatic dredge pump; one side of the annular cylinder is provided with an opening; the grid plate is fixed at the opening and is welded to be of a reticulated shape by using a steel bar; two ends of the annular cylinder are sealed; one end of the mud-feeding pipe is connected with the annular cylinder, and the other end of the mud-feeding pipe extends into each pneumatic dredge pump; and three pneumatic dredge pumps in one group are connected to the annular cylinder. When dredging is performed for deep water, the annular cylindrical mud-feeding shovel is closely adhered on the surface of undisturbed soil to rapidly remove siltation soil at the upper layer of the undisturbed soil, and the conditions that the mud-feeding shovel exceeds the depth of dredging or does not meet the requirement of dredging during working due to the influence of tide level and waves are avoided. The annular cylindrical mud-feeding shovel has the advantages that the annular cylindrical mud-feeding shovel is long in span and high in work efficiency, and can be closely adhered on the surface of the undisturbed soil, meets the requirement of dredging and rapidly removes the siltation soil on the undisturbed soil.

Description

Annular cylinder shape advances mud shovel

Technical field

The utility model belongs to a kind of mud shovel that advances, and particularly a kind of to advance the mud shovel span long, advances mud shovel and can be close on the undisturbed soil surface, and the annular cylinder shape of high efficiency advances mud shovel.

Background technology

At present, during depth of water maintenance dredging, dredging dark General Requirements is design head, and the soil that then will back-silt all scoops away and gets final product, yet due in water-bed operation, be subject to the impact of tidal level and wave, make to dig and deeply be difficult to control, dig dark control tight do not reach and dredge dark requirement, slightly do not control, will occur super deeply, this is a great problem in the engineering construction of depth of water maintenance dredging, especially with water surface operation ship, takes the pneumatic sludge sucking pump be flexible coupling more to seem serious.

Summary of the invention

The utility model provides for solving the problem existed in known technology that a kind of to advance the mud shovel span long, advances mud shovel and can be close on the undisturbed soil surface, and the annular cylinder shape of high efficiency advances mud shovel.

The technical scheme that the utility model is taked for the problem existed in the solution known technology is: it comprises pneumatic sludge sucking pump and advances mud shovel, it is characterized in that: advance mud shovel and comprise ring cylinder, screen and advance the mud pipe, advance the mud pipe and communicate with pneumatic sludge sucking pump, be designed with on pneumatic sludge sucking pump into mud pipe, sludge out pipe with into and out of tracheae.

The utility model can also adopt following technical scheme:

One side of described ring cylinder is the opening shape, and ring cylinder one end is shut, other end stationary grid;

Described screen is welded into clathrate with steel bar;

Describedly advance mud Guan Yiduan and be connected with the ring cylinder, the other end stretches in pneumatic sludge sucking pump;

Be connected with one group of three pneumatic sludge sucking pump on described ring cylinder.

Advantage and the good effect that the utlity model has are: it is long that annular cylinder shape advances the mud shovel span, advances mud shovel and can be close on the undisturbed soil surface, can reach and dredge dark requirement and remove rapidly the soil that back-silts on undisturbed soil, high efficiency.

The accompanying drawing explanation

Fig. 1 is overall structure schematic diagram of the present utility model.

In Fig. 1: 1. advance mud shovel, 2. encircle cylinder, 3. screen, 4. advance the mud pipe,

5. pneumatic sludge sucking pump, 6. sludge out pipe, 7. into and out of tracheae.

The specific embodiment

For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows, refer to Fig. 1

As shown in Figure 1: advance mud shovel 1 and comprise ring cylinder 2, screen 3 and advance mud pipe 4, advance mud pipe 4 and communicate with pneumatic sludge sucking pump 5, be designed with on pneumatic sludge sucking pump 5 into mud pipe 4, sludge out pipe 6 and turnover tracheae 7; The front lower place of described ring cylinder 2 is 90 ° of openings, and the diameter of ring cylinder 2 is that 1m, length are that 6m, steel plate thickness are 12cm, and the opening part of ring cylinder 2 is welded with screen 3, and screen 3 use steel bars are welded into clathrate, and shut with steel plate at two of ring cylinder 2; Describedly advance mud pipe 4 one ends and be connected with ring cylinder 2, the other end stretches in pneumatic sludge sucking pump 5; Ring cylinder 2 is along being fixed with respectively one group of three pneumatic sludge sucking pump 5 on ladle body length, ring cylinder 2 advance mud pipe 4 be pneumatic sludge sucking pump 5 advance mud pipe 4; Maintain when dredging in the depth of water, annular cylinder shape advances mud shovel 1 to be close on the undisturbed soil surface, can not compress into the original state soil layer downwards, moves on not understanding again and aweigh, guarantees the accuracy that dredging depth is controlled; When advancing mud shovel 1 and advancing, remove rapidly the soil that back-silts on undisturbed soil upper strata, can not be subject to the impact of tidal level and wave and occur into mud shovel 1 super dark or do not reach and dredge dark requirement when the work; Ring cylinder 2 interior advanced silts advance mud pipe 4 and are siphoned away by the pneumatic sludge sucking pump 5 of rear side by what join.

Its advantage is: it is long that annular cylinder shape advances the mud shovel span, advances mud shovel and can be close on the undisturbed soil surface, can reach and dredge dark requirement and remove rapidly the soil that back-silts on undisturbed soil, high efficiency.

Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
