Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, an environment-friendly dredging device with a hob comprises a hob box 1, wherein the hob box 1 is of a square block structure, a hob groove 2 is formed in the side wall of the hob box 1, the inner walls of the two sides of the hob groove 2 are rotatably connected with three connecting shafts 3 through bearings, a hob 7 is welded on each two connecting shafts 3 corresponding to each two positions, the connecting shaft 3 located in the middle position and the connecting shafts 3 on the two sides are connected through a transmission device, a machine case 9 is welded on the side wall of the hob box 1, a motor 10 is welded on the inner wall of the machine case 9, a connecting hole 8 is formed in the side wall of the hob box 1, an output shaft of the motor 10 penetrates through the connecting hole 8 and is rotatably connected with the inner wall of the connecting hole 8 through a bearing, the output shaft of the motor 10 is welded with the connecting shaft 3 in the middle position, a discharge hole 12 is formed in the side wall, the end of the flexible box 13 remote from the hob box 1 is glued with a suction pipe 14.

The transmission device comprises a large gear 5 and a small gear 6, wherein both the large gear 5 and the small gear 6 are rotatably connected with mounting shafts 4 through push rod bearings, and the mounting shafts 4 are welded on the side walls of the hobbing cutter grooves 2; the big gear 5 is meshed with the connecting shaft 3 in the middle, the small gear 6 is meshed with the corresponding connecting shafts 3 on the two sides, and the big gear 5 is meshed with the small gear 6.

The outer wall of the sludge suction pipe 14 and the outer wall of the hob box 1 are welded with the telescopic rod 11 together, the elastic box 13 is made of rubber materials, and has good deformation capacity, so that the working position of the hob box 1 can be ensured when the telescopic rod 11 is adjusted; the number of teeth of each big gear 5 is more than that of the small gear 6, so that the hobbing cutters 7 at the middle positions are in accelerated transmission to the hobbing cutters 7 at the two sides, pressure difference is further caused, and sludge is convenient to collect; the discharge opening 12 is positioned right above the three rolling cutters 7, so that the sludge after stirring can be discharged from the discharge opening 12 in time.

When the river course silt clearance is carried out to appointed area in the needs, can be according to the thickness of the silt that needs the clearance in the region, come the length of suitable adjustment telescopic link 11, in order to realize the depth of fall of whole hobbing cutter case 1, realize effectively clearing up required silt, and do not harm lower floor's bed mud, play the guard action to the riverbed, because the design of elastic box 13, deformation through elastic box 13 self, when making the adjustment of hobbing cutter case 1 position, keep suction pipe 14 and hobbing cutter case 1 in operating position, elastic box 13 communicates hobbing cutter case 1 with suction pipe 14 simultaneously, guarantee the effective transport of silt.

After the position of the hob box 1 is adjusted, the motor 10 can be started, under the driving action of the motor 10, the connecting shaft 3 in the middle position starts to rotate, the connecting shaft 3 in the middle position drives the two large gears 5 to rotate, the large gears 5 drive the small gears 6 to rotate, so that the connecting shafts 3 on two sides also rotate along with the large gears, each connecting shaft 3 rotates to drive the hob 7 connected with the connecting shaft to start to rotate, once the hob 7 rotates, sludge can be stirred and is driven to move, the sludge is lifted after being stirred, the sludge is sucked by the sludge suction pipe 14, the stirred sludge moves to the sludge suction pipe 14 through the discharge port 12, and finally the sludge is discharged, so that the residual sludge at the bottom of the riverbed is cleaned.

Because of the transmission of the gear wheel 5 and the pinion 6, the hobbing cutter 7 at the middle position is opposite to the hobbing cutters 7 at the two sides, the sludge is stirred back and forth at the place where the hobbing cutter box 1 passes through, so that the sludge is stirred thoroughly, and the sludge is cleaned effectively, because the gear wheel 5 is smaller, the gear 6 has more teeth, when the rotation process is transmitted from the middle position to the two sides, the speed-up transmission is realized, namely, the rotating speed of the hobbing cutters 7 at the two sides is faster than that of the hobbing cutter 7 at the middle position, so that the different positions have flow speed difference in the stirring process, so that pressure difference is formed among the different positions, the sludge at the different positions is gathered towards the middle under the action of pressure after stirring, and cannot be randomly diffused due to stirring, the sludge is conveniently transported by the sludge suction pipe 14, and the secondary pollution of a water body caused by the sludge diffusion is avoided, and the cleaning position is, the diffusion of silt after also can the restriction of certain degree stirs plays the guard action to each hobbing cutter 7 simultaneously, avoids hobbing cutter 7 to be died by the hank such as pasture and water, has guaranteed the effectual cleaning action of device.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
