Please refer to Fig.1 to Figure 16, the embodiment of the present invention provides a kind of dredger, including hull 1, mud collection device 2,
Smash device 3, dehydration device 4 and defeated mud channel 5.Reducing mechanism 3, dehydration device 4 and defeated mud channel 5 may be contained on hull 1,
Mud collection device 2 is connect with hull 1.Specifically, mud collection device 2 can be arranged on stem, forward extend out in hull
1, and stretch into the bottom.Ship stern is also provided with mud transmission device 7, for dewatered mud to be transmitted to and the dredger
On the sludge boat of auxiliary work.Mud collection device 2, reducing mechanism 3 and dehydration device 4 are sequentially connected by defeated mud channel 5.It becomes silted up
Mud collection device 2 may be used the modes such as milling digging, suction and water-bed mud be collected on hull 1, smash device 3 for that will become silted up
Mud collected by mud collection device 2 crushes, and the bulk rubbish in mud is crushed, the mud after crushing is by defeated mud channel
5 are transported to dehydration device 4, and dehydration device 4 is used to mud carrying out drying dehydration, and water is discharged to outside hull 1, makes the weight of mud
Amount is greatly reduced, and reduces the workload of subsequent sludge boat.Cockpit 11 is also provided on hull 1, operator can
To manipulate the dredger in cockpit 11.
It please refers to Fig.3 and Fig. 4, mud collection device 2 includes track support frame 21, crawler belt 22, shaft 24,25 and of driver
Multiple milling buckets 23.Track support frame 21 connect and is tilted with hull 1 and stretched out in outside hull 1, and stretch into the bottom.Specifically,
For track support frame 21 substantially in cuboid, the bottom, the other end (first end) of long side are stretched into one end (second end) of long side
On hull 1.Shaft 24 is rotatably connected on track support frame 21.Length direction of the crawler belt 22 along track support frame 21
It is movably attached on track support frame 21, and coordinates with shaft 24, with the rotation of shaft 24, crawler belt 22 is in crawler belt branch
Cycle rotation on support 21, and be embodied on a long side outer surface of track support frame 21, then crawler belt 22 is in crawler belt
It is translated on the outer surface of supporting rack 21.Multiple milling buckets 23 are connect with crawler belt 22, in track support frame under the drive of crawler belt 22
It is moved on 21, the quarrel direction of milling bucket 23 is identical with the moving direction of crawler belt 22.Milling bucket 23 is moved to shoe with crawler belt 22
When stretching into water-bed one end with supporting rack 21, water-bed mud is dug, crawler belt branch is then moved under the drive of crawler belt 22
Support 21 is located at one end on ship, mud is poured into the feed hopper 31 of reducing mechanism 3, and continues to stretch into towards track support frame 21
Water-bed one end movement, multiple milling buckets 23 so move in circles, and dredging efficiency is higher.The quantity of milling bucket 23 is set as needed
It puts, generally between 15 to 30.Driver 25 is connect with shaft 24, is rotated for drive shaft 24, and shaft 24 is used for band
Dynamic crawler belt 22 rotates on track support frame 21.In the present embodiment, the both ends of track support frame 21 are respectively arranged with one and turn
Axis 24, each shaft 24 can be connect with a driver 25, can also only one shaft 24 connect with driver 25.
Track support frame 21 has bottom surface 212 and top surface 211, and bottom surface 212 is towards where the water surface and hull 1, directed downwardly and long side
Face, top surface 212 be it is opposite with bottom surface, upward and long side where face.In a preferred embodiment, positioned at track support frame
Crawler belt 22 and milling bucket 23 on 21 top surface 211 are moved from the second end of track support frame 21 to first end, positioned at bottom surface
Crawler belt 22 and milling bucket 23 on 212 are moved from the first end of track support frame 21 to second end, since track support frame 21 is
It is obliquely installed low early and high afterly, milling bucket 23 can be made to have dug after mud when being moved on track support frame 21 quarrel upward in this way,
More mud can be contained in this way, and can guarantee the flatness in riverbed.In a further preferred embodiment, shaft 24 is side
Shape axis, driver 25 are hydraulic motor.Square shaft can preferably coordinate with crawler belt 22.Moreover, using square shaft as shaft
24, even if certain abrasion has occurred in square shaft, remain able to that crawler belt 22 is driven to rotate, so that mud collection device 2
Service life is longer.The equipment such as the normal usage mining machine of traditional dredger, grab bucket are dredged, but these equipment are dredged, and are being dug
When bucket is dug, have many mud toward contact and fall back to river bed again, dredging is not clean, and is also easy to dig out in river bed circular
Hole, makes the out-of-flatness of riverbed bottom.Formula mud collection device 2 is dug by using the milling of the present embodiment, it can be clear by the mud of river bed
It digs totally, and can guarantee the smooth of riverbed bottom.
In a further preferred embodiment, the first end of track support frame 21 is located on hull 1, and second end is far from hull
1 and less than hull 1, the bottom is stretched into, track support frame 21 is rotatably connected with hull 1.Specifically, track support frame 21 is close
The position of first end can be hinged by shaft and hull 1, the direction of travel for being axially perpendicular to hull 1 of shaft.Mud is collected
Device 2 further includes milling and digs adjustment oil cylinder 26, and the first end that adjustment oil cylinder 26 is dug in milling is hinged on hull 1, and second end is connected to shoe
On band supporting rack 21, and the second end of milling digging adjustment oil cylinder 26 is carried out relative to the junction of track support frame 21 and hull 1 is close
Second end (stretching into water-bed one end) with supporting rack 21, so as to which milling be made to dig first end, second end and the crawler belt of adjustment oil cylinder 26
One that adjustment oil cylinder 26 is the triangle is dug in three vertex triangle with the hinge joint of hull 1 of supporting rack 21, milling
Side.When needing to adjust milling digging depth, it is only necessary to adjust the collapsing length that adjustment oil cylinder 26 is dug in milling, adjustment oil cylinder 26 is dug in milling
Length it is shorter, track support frame 21 it is bigger relative to the angle of inclination of the water surface, the second end of track support frame 21 stretches into water
In it is deeper so that milling is dug, depth is deeper, on the contrary, the length that adjustment oil cylinder 26 is dug in milling is longer, then the of track support frame 21
Two ends stretch into it is more shallow in water, milling dig depth it is more shallow.When dredger completion dredging operation, milling digging adjustment oil cylinder 26 is extended to longer
Degree, makes the second end of track support frame 21 not contacted with the bottom, is navigated by water convenient for dredger.
In a preferred embodiment, dredger further includes locating module, control module and storage device (not shown), positioning mould
Block, storage device and milling are dug adjustment oil cylinder 26 and are connect with control module, and locating module is used to detect the position of dredger, storage dress
It puts memory and contains electronic drawing, control module digs the length of adjustment oil cylinder 26 according to the position of dredger and electronic drawing control milling
Degree.Specifically, locating module can be GPS positioning module, GSM locating modules etc., and control module can be programmable logic
Controller (PLC), microcontroller etc., storage device can be the internal memory of dredger, or the external storage such as USB flash disk
Device.Electronic drawing can be provided by the party awarding the contract of dredging engineering, wherein comprising boundary of works area, water-bed pattern, altitude datum, everybody
It puts milling and digs the construction parameters such as depth.During construction, the position of parameter request and dredger of the control module in electronic drawing, from
The length of adjustment oil cylinder 26 is dug in dynamic control milling, thus digs depth to adjust the milling of mud collection device 2.This control mode can
Effectively elevation is dug in punctuality control, guarantee milling.
It please refers to Fig.4, in a further preferred embodiment, mud collection device 2 further includes hydraulically extensible adjuster 27,
