Abstract
The invention discloses an anti-blocking device for a dirt sucking head, which comprise a power source, a power transmission device, a reeling star wheel group and a shell, wherein the reeling star wheel group comprises two groups of reeling star wheels which are arranged in parallel and do rotary motion in a way of being close to each other or being crossed and overlapped, the power transmission device reduces the speed of the power of the power source and then transmits the power to the two groups of reeling star wheels simultaneously, and the two groups of reeling star wheels do reversing rotation outwards simultaneously; the reeling star wheel group is supported on the front wall and the rear wall of the shell, the bottom part and the mid-lower parts of the two sides of the shell are open, and a dirt sucking opening connected with a dirt sucking device is arranged at the upper part of the shell. The anti-blocking device can effectively prevent sundries in a river channel, which are likely to block a dirt sucking pipe, from entering the dirt sucking pipe, and the purpose that the dirt sucking pipe can perform dirt sucking operation continuously is achieved.
Description
Technical field
The present invention relates to a kind of soil pick-up equipment, particularly a kind of anti-blocking device for dirt sucking head.
Background technology
Since the eighties in last century, along with the expansion of expanding economy and urban population, because the infrastructure constructions such as sewerage treatment lag behind, a large amount of industrial wastewaters and sanitary sewage directly enter inland river, Water Environment in Urban Rivers constantly worsens, there is severe siltation phenomenon in River Channel, causes original passable river course to open the navigation or air flight, and inland river water drainage ability is also had a greatly reduced quality.In recent years, in order to improve the common people's quality of life, government goes into overdrive inland river to renovate, and wherein desilting work in inland river is its important ingredient.Traditional manner of cleaning up of riverway sludge is first river to be drained, more directly enters river course cleaning mud by personnel, but desilting efficiency data is extremely low and workman's misoperation easily occurs, and the safeguard structures such as riverbed and bank protection are damaged.At present, there is company to propose to adopt hull to carry soil pick-up and equip the processing scheme that the rancid mud in Ha Noi is cleared up, to reach the object of cleaning river course and purifying river water.This scheme not only, without drain river in the situation that, completes the cleaning of mud.Can also, by detecting control technology, to riverbed, carry out supple-settlement, be unlikely to riverbed to damage.But in this scheme specific design implementation process, there are the following problems: because inland river sewage ill-conditioned (the life waste material that contains the difficult degradations such as clothes, cloth, plastics) sewage absorpting heat can occur unavoidably or soil pick-up equipment pipe results in blockage, affect the suction of mud, mud cleaning efficiency is affected.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and provide one can prevent that sewage absorpting heat from being wrapped by clothing cloth or other large life waste material and occurring that sewage absorpting heat cannot draw mud or reduce mud cleaning efficiency, guarantee river course soil pick-up operation, improve a kind of anti-blocking device for dirt sucking head of soil pick-up efficiency.
A kind of anti-blocking device for dirt sucking head, its structural feature is: include power source, actuating unit, straw-poking star wheel group and housing, described straw-poking star wheel group include two groups be set up in parallel and mutually near or the straw-poking star wheel that does gyration arranged of juxtaposition, actuating unit is by by the straw-poking star wheel that after the dynamic retarding of power source, power is passed to two groups simultaneously, two groups of straw-poking star wheels do outside rotating backward simultaneously, described straw-poking star wheel group be supported in housing before, on rear wall, the bottom of housing and the middle and lower part of both sides are open type, on the top of housing, be provided with the sewage discharge tube being connected with soil pick-up equipment.
In soil pick-up equipment, add this anti-blocking device for dirt sucking head, in use, sewage discharge tube in anti-blocking device for dirt sucking head is connected with soil pick-up equipment, start anti-blocking device for dirt sucking head, power source will drive actuating unit motion, thereby drive two straw-poking star wheels that are set up in parallel to turn reverse gyration, doing counter-rotational two straw-poking star wheel groups can effectively separate large-sized fiber journal or stone from mud and sewage, by the housing open-mouth of both sides, dished out again, do not contain clothing cloth or other large life waste sludges and can by the sewage discharge tube that is arranged at case top, enter soil pick-up equipment easily.
Both sides at housing are also provided with antiseized jaw, and described antiseized jaw is fixed on the both sides of housing, and the straw-poking star wheel gap of antiseized jaw and both sides is staggered.
Due to still gapped between straw-poking star wheel and object, the particularly good fiber of some toughness can again be clamp-oned under the effect of dirt-absorbing ability from gap, edge, thereby affects the motion of straw-poking star wheel.For the anti-impact in gap here, in the left and right sides of straw-poking star wheel object, add an antiseized jaw, staggered with the straw-poking star wheel gap of the left and right sides.Stop fiber or other impurity gap, to enter outside straw-poking star wheel.
Described actuating unit is Worm Wheel System, and power source is connected with worm screw, then drives two worm gears to do gyration by the worm screw of, and the worm-wheel shaft while is as the turning cylinder of two groups of straw-poking star wheels.
Worm and gear slows down as actuating unit and rotation direction conversion, and the power that level is imported into carries out vertical rotary conversion.The object of slowing down is to improve output torque, reduces motor rotary speed.
Described actuating unit can also be to drive to pass device or gear drive.
Described power source is hydraulic motor or motor.
In sum, the present invention's following advantage compared to existing technology:
This device is by power source, through actuating unit, slow down also, drive two groups of star-wheel groups that formed by multi-disc straw-poking star wheel to rotate simultaneously, thereby produce the effect of outwards being stirred by star-wheel enclosure interior, can effectively intercept the river course foreign material that may block dirt sucking tube and enter dirt sucking tube, the object that reaches dirt sucking tube and carry out continuously soil pick-up operation.Simultaneously, owing to having increased antiseized jaw in the both sides of housing, just having made gap between housing and star-wheel, star-wheel and star-wheel can guarantee sewage and fluidised form mud is smooth and easy enters dirt sucking tube by star-wheel housing, can prevent that again bulk foreign material from entering housing.
