Description
Technical field
The utility model relates to a kind of dredger more particularly to a kind of backhoe dredgers.
Background technique
In certain engineering constructions, the training of channel needs to remove the block stone of upper layer silt and lower layer, the phases such as bottom absolute altitude, gradient
It is high to close technical indicator design requirement.Due to the condition limitation that the river scene depth of water is shallow and working face is small, some conventional constructions are set
Standby to inhale ship, bucket wheel formula sand removal ship, bath mortar pumping station energy desurfacing silt as Conventional compact twists, block stone can not but excavate.Chain
Bucket-ladder dredger and grab bucket dredger can remove lesser block of stone of silt and diameter, but such ship size is big, and drinking water is deeper, need
Mating barge assists completing construction task, and is not suitable for excavation slope.Therefore, it is necessary to a kind of dredging suitable for the training of channel
Ship.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of training of channel efficiency for the status of the prior art
The good backhoe dredger of higher and construction quality
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of backhoe dredger, including barge
And it is set to the backacter on barge, the mining head for excavation is provided on the digging arm of the backacter,
The mining head includes the first mining head and the second mining head for the backhoe type that can mutually replace, and second mining head includes
The bucket for the backhoe type that can be detachably connected with the digging arm, and the hydraulic mortar being set on the lateral wall of the bucket
Pump, the hydraulic mortar pump are connect with the pipeline for transporting the mortar drawn.
Further, the latticed pump cover for filtering stone is additionally provided on the hydraulic mortar pump.Pump the setting of cover
Prevent stone from destroying the cutter piece of pump.
Further, it is provided with three guide piles on the barge, is respectively arranged at larboard, the starboard at the middle part of the barge
And the centre of tail portion.After river bed is squeezed into positioned at midship two guide piles, to bear excavator when excavating block stone
Opposite force guarantees that hull stabilization is not subjected to displacement.The guide pile of stern mainly reaches design in the construction of local section bottom absolute altitude
After it is required that, using the stake as the center of circle, two sides the dredging operation of next step and can be continued with the mobile ship of sector to the left and right.
Compared with the prior art, the advantages of the utility model are: barge shallow draft, mobile flexible, convenient in river
It is mobile, and combine there are two the backacter that can mutually replace the first mining head, the second mining head, when cleaning upper layer silt particle
When, using the second mining head, after silt particle is stirred, transfer out excavation range；When clearing up lower layer's stone area, it is changed to the first excavation
Head directly excavates, and construction efficiency is higher, and can realize required technical indicator well, and construction quality is good.
Detailed description of the invention
Fig. 1 is the integrally-built side schematic view of the backhoe dredger of the embodiments of the present invention；
Fig. 2 is the side schematic view of first mining head of the embodiments of the present invention；
Fig. 3 is the side schematic view of second mining head of the embodiments of the present invention；
Fig. 4 is the structural schematic diagram of the hydraulic mortar pump of the embodiments of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 4, a kind of backhoe dredger, including barge 1, the backacter being set on barge 12 with
And the driver's cabin 4 for driving barge 1.It is provided with the mining head 22 for excavation on the digging arm 21 of backacter 2, excavates
First 22 include that the first mining head 22a and the second mining head 22b, the second mining head 22b of backhoe types that can mutually replace include
The bucket 22c for the backhoe type that can be detachably connected with digging arm 21, and the hydraulic sand being set on the lateral wall of bucket 22c
Stock pump 22d, hydraulic mortar pump 22d are connect with the pipeline 22e for transporting the mortar drawn.The hydraulic mortar pump of the present embodiment
The back side of bucket 22c, the model HY-85A hydraulic pump of hydraulic mortar pump 22d, discharge capacity 200-240m is arranged in 22d3/ h takes out
Height 22-30m, weight 700kg are inhaled, channel cross-section diameter is 60mm, and power of motor 44-62kW, specific structure can be with reference to figure
4。
First mining head 22a of backhoe type is mining head commonly used in the prior art, is repeated no more to its structure, this implementation
About 1.0 side of capacity for the first mining head 22a that example uses, digging force 180kN, rated power 132kW/rpm, maximum digging depth
6950mm。
The latticed pump cover 22f for filtering stone is additionally provided on hydraulic mortar pump 22d.Pump cover 22f can lead to
The modes such as buckle or threaded connection are crossed to be connected on hydraulic mortar pump 22d.
It is provided with three guide piles 3 on barge 1, is respectively arranged at midship larboard, starboard and the centre of tail portion.This
The guide pile 3 of embodiment is that anchor is pull-type, and stake uses the solid circular steel column of diameter 18cm, and length 9.5m weighs about 2 tons certainly, plays stake and sets
Standby is to carry the hoist engine that pulling force is 5 tons.After river bed is squeezed into positioned at midship two guide piles, dug to bear excavator
Opposite force when except block stone guarantees that hull stabilization is not subjected to displacement.The guide pile 3 of stern is mainly applied in local section bottom absolute altitude
After work reaches design requirement, using the stake as the center of circle, two sides dredging for next step and can be continued with the mobile ship of sector to the left and right
Dredge operation.
When using this kind of backhoe dredger, pipeline 22e is first arranged, the backhoe dredger of having good positioning.First install second
Mining head 22b stirs silt particle with bucket 22c on one side, aspirates upper layer silt particle with hydraulic mortar pump 22d on one side, and utilize pipeline 22e
By sand transport to specified region.When being cleaned to stone area, lower layer, it is changed to the first mining head 22a, with the mining head to stone
It is excavated in block region.
