Abstract

The utility model relates to a shallow water dredger which is a tool used for dredging and clearing the sludge of ponds, ditches, rivers and lakes. Dynamic force is transferred by a diesel or an electric motor installed in a ship hull through a main spindle, an intermediate shaft and an auxiliary shaft to a forward mud dredger extended out the ship hull in order to dig and suck the sludge, injecting into an accumulation sludge bin. The sludge is pumped and discharged by a mud pump in the accumulation sludge bin, which is discharged out of the ponds by dredging pipes. The shallow water dredger used with the diesel of 9.5 horsepower together can reach a lift of 5-10m and a transferring distance of 100-200m, and the discharging sludge quantity can reach about 30m<3> per hour. The sludge concentration can reach 95%. The utility model improves the discharging sludge effect of foreign matters of hard soil or sludge which carried bricks, stones, fibers, etc., which has the advantages of high work efficiency, good quality, etc. in shallow water working.

Description

Shallow water dredger

The utility model relates to a kind of facility of removing underwater sludge of dredging, and is particularly suited for dredging the mud of removing pond, irrigation canals and ditches, lake, river.

Existing underwater silt remover tool mostly is vexed suction formula, promptly sink to vexed suction mud at the bottom of the pool by soil-suction head (dish) or slusher, its effect generally can only be dredged the rarer soft pasty state mud of removing under water, its mud concentration is all in that (mud concentration means that silt things such as silt mix with water below 90%, after precipitating 24 hours, the silt thing accounts for the percent by volume of its mixture, following its connotation of mud concentration is identical), therefore make earth dyke be difficult to accumulation holds on the pool outside, another drawback of these class facility is, dig pan soil at the bottom of the pool for deepening to attack, or be entrained with fragment of brick in the mud, foreign material such as sandstone and fiber are all powerless.As " the SQY7 type dive away formula pond dredger " of Xinjing Machinery Factory, Shanghai's production and sales, though multiple functions such as tool desilting, irrigation and drainage, the oxygen that exposes to the sun adopt slusher and diving slurry pump to aspirate mud, its mud concentration has only 30-70%; By " the QXG2010 type fishes and shrimps pool underwater silt remover ship " of the production and sales of Zhejiang Wenzhou Fishery Machinery ﹠ Electric Appliance Making ﹠ Repairing Factory though can disposablely finish and inhale mud, send mud, the whole operations of dump, but at the bottom of sinking to the pool by soil-suction head, mud is by outside soil-suction head, suction pipe, the slush pump suction pool, and its mud concentration is 80-90%; And for example number of patent application be 902092901 and 902081519 by " the CTZ type fish pond desilting motor vessel " of Guangdong Province's Shunde County agricultural machinery two factories production and sales though multiple advantages such as tool small portables, its mud concentration reaches 80-95%, but owing to adopt mud sucking disk, the rarer soft pasty state mud of suction only can not be deepened to attack and be dug pan soil at the bottom of the pool; Also " the huge legendary turtle board waterpower fish pond excavator group " just like the production and sales of Taixing, Jiangsu Province county fishery machinery factory is provided with high-pressure hydraulic pump, impact pan soil by hydraulic giant and make outside its mud mixture pump drainage pool that forms loose mud or little clod, this has solved a construction technology difficult problem to excavating new pond or transforming the old pond of intensification.But because above-mentioned several all low of its mud concentration ratio, and need 4 people operation, its labour intensity is bigger, therefore generally under water the desilting place be difficult to apply.

Purpose of design of the present utility model provides a kind of desilting concentration height, can deepen to attack the shallow water type desilting facility that dig pan soil at the bottom of the pool.

The utility model is combined by modular constructions such as hull, power, main shaft, jackshaft, countershaft, mud dredger, dashboard, slush pump, dredging tubes, and its design scheme is:

With diesel engine or the motor source that is used as power, it is placed in middle part one side of hull underframe; Mud dredger stretches to the middle part that hull the place ahead is placed in the hull front end, and the minimum point line of its impeller is a little less than the hull bottom horizon; Slush pump is arranged on the angle, the preceding right side (left side) in the hull, adheres to the hull shell wall from mud dredger to slush pump and is set to the deposition logical sequence; Main shaft is from the unison hull underframe that is located at after the slush pump of the same level of blade wheel of slurry pump axis hole, and its middle part is equipped with handle and stretches near the operations chair clutch, and its front end wears with the impeller axis hole of slush pump by sealing and securing member and links to each other; Countershaft and main shaft are set in parallel on the center line of hull underframe, and its front end stretches out the hull shell wall and interlocks by sealing and securing member and mud dredger; The parallel main shaft that is located at main shaft of jackshaft is to hull (15) upper beam of countershaft.All be equipped with 1-2 belt pulley at the rear portion of main shaft, countershaft and the middle part of jackshaft.And the belt pulley of main shaft tail end equals the belt pulley of jackshaft, and then the belt pulley of countershaft is greater than the belt pulley of jackshaft, or the belt pulley of countershaft equals the belt pulley of jackshaft, and then the belt pulley of main shaft tail end is less than the belt pulley of jackshaft; Its transmission of power can be with the output wheel of diesel engine or motor and the belt wheel hanging sleeve belt of main shaft, the belt wheel of main shaft again with the belt wheel hanging sleeve belt of jackshaft, the belt wheel of jackshaft again with the belt wheel deceleration hanging sleeve belt of countershaft, thereby mud dredger being dug inhale mud injects the deposition logical sequence, slush pump constantly with the mud pump drainage of deposition logical sequence outside dredging tube is discharged the pool.

The edge axle has the spiral arc plate impeller of introversion to the utility model or leading portion has a plurality of impellers that turn the shape sheet owing to mud dredger is designed to, and the minimum point line of its impeller is a little less than the hull bottom horizon.Thereby increased and attack the function of digging pan soil at the bottom of the pool, and keep smooth smooth at the bottom of the pool again, again owing to have at the front end of mud dredger impeller and rear end axostylus axostyle sliding sleeve and can make 180 dashboards that spend deflections above the impeller.Therefore desilting is dug when inhaling and has been avoided mud to spread arbitrarily.

Be equipped with a near vacuum meter that stretches to the operations chair at the top of deposition logical sequence, can show that mud in the deposition logical sequence becomes silted up to annotate row's situation, be convenient to observe regulation and control; Hull outer wall at deposition logical sequence place has a drain hole, and its aperture is equipped with one and can only overflows the valve that part water (gas) is forbidden to enter, thereby has improved the concentration of mud.

Be equipped with a near pressure meter that stretches to the operations chair at slush pump outlet top, can show the mud pump drainage situation in the dredging tube again, be convenient to observe regulation and control; Outwards have row's barrier hole in slush pump import department, its aperture is equipped with one can only discharge foreign material such as exceeding pump housing caliber fragment of brick, sandstone and unadmitted valve, thereby reduces and avoid the obstruction of mud conveying pipeline, keeps unimpeded unlikely cutout.

The utility model can be at pond, irrigation canals and ditches or lake, the river dredging operation of 50-70cm deep water, can deepen to attack and dig at the bottom of the pool about pan soil 10cm, its concentration can reach 80-95%, to being entrained with foreign material such as fragment of brick, sandstone or fiber in the mud, has improved the pump drainage effect greatly than existing dredger simultaneously.
