A kind of mud scraper screeding device of the patent No. 201310072890.2 also needs to adjust lifting ... manually that patent all belongs to quilt in sum
Dynamic lift mud scraper category, these mud scrapers equally have the defect of fixed mud scraper.
Existing market has the application of scraping and sucking machine, will make with holes or groove discharge pipeline, discharge pipeline and precipitation into by cleaning shoe
The fixed sleeving that pond center stands vertically is flexibly connected, and center sleeve is connected with sludge pump outside pond realizes suction-discharge.This technology
The flatness requirement to sedimentation tank at the bottom of pond can be reduced, but equally can cause when mudhole or groove local stoppages to be detained sludge anaerobic
The phenomenon floating with gas.
For this reason, mud scraper often needs to arrange worn-out slag machine while scraping mud floating sludge is cleared up in sum.
Content of the invention
Present invention aim at solving existing mud scraper to sedimentation tank at the bottom of pond flatness requirement height, mud cleaning is thorough,
The critical problem floating after causing to be detained sludge anaerobic band gas, provides a kind of center realizing automatic lifting by scraper plate deadweight
Transmission lift mud scraper.
Center driving lift mud scraper of the present invention mainly by reducing motor, Hollow Transmission Shafts, center intake chamber,
Hollow Transmission Shafts disconnect piece, perforation water distribution tube, scraping arm gimbal lever draught line, scraping arm, the gimbal lever, balanced body, gravity lifting
Cleaning shoe, the water inlet of sludge agitation Qi He center connect running-on composition, and reducing motor is located at work crane span structure F center, by shaft coupling
Couple with Hollow Transmission Shafts, Hollow Transmission Shafts disconnect formation center intake chamber, realize the upper and lower of Hollow Transmission Shafts by connection sheet
Connect, perforation water distribution tube is fixedly connected with Hollow Transmission Shafts by upper and lower bottom plate；Scraping arm, the gimbal lever are drawn by the scraping arm gimbal lever
Line is connected with Hollow Transmission Shafts, and balanced body is fixed on the end of the gimbal lever；Gravity lifting cleaning shoe and scraping arm pass through master connecting-rod with
Slave connecting rod is flexibly connected with screw, and it is offset plate that connecting rod side is leaned in cleaning shoe bottom, and another side two ends are fixed with left chain wheel, right cunning
Wheel, cleaning shoe is polylith, has side roller by first piece of scraper plate of pool side by pool wall one end；Sludge agitation device top and Hollow Transmission Shafts
Connect running-on to be fixedly connected, adapter sleeve muzzle is on the center water inlet pipe B standing vertically.
Cleaning shoe is fixedly connected with master connecting-rod, and master connecting-rod is flexibly connected by secondary screw with slave connecting rod, and master connecting-rod passes through the right side
Screw is flexibly connected with scraping arm, and slave connecting rod is flexibly connected with scraping arm by left screw.Constitute cleaning shoe and scraping arm
It is flexibly connected.
Operation principle：
Pass through Hollow Transmission Shafts through sedimentation tank bottom centre water inlet pipe, center intake chamber enters upper-lower seal after biochemical sewage
Perforation water distribution tube, after sewage perforated water distribution tube rectification from side to periphery spread, thus avoid stabilizing feed well bottom diffusion
Cause side dead angle area, make perforation water distribution tube diffusion velocity significantly be less than stabilizing feed well water distribution, thus extending dwell time of sewage,
Sludge settling effect is made to improve.
During mud scraper work, reducing motor pulls scraper plate to circle by Hollow Transmission Shafts, scraping arm, in order to realize scraping
Mud angle most preferably scraped by plate, and scraping arm adopts 90 ° of right-angle bendings to extend, and realizes being flexibly connected scraper plate by connecting rod, screw；Cleaning shoe with
At the bottom of pond contact is mobile to adopt pulley force controlled, realizes automatic lifting by cleaning shoe deadweight, even if at the bottom of pond flatness is slightly poor
Do not affect mud cleaning.Cleaning shoe work adopts pulley force controlled, reduces the horizontal torsion of Hollow Transmission Shafts and the electricity that slows down
Function consumes.
Scraping arm is symmetrical centered on Hollow Transmission Shafts with the gimbal lever, and the gimbal lever, the application of balanced body make hollow transmission
The center water inlet pipe that the connection running-on side of axle is stood vertically with sedimentation tank bottom contacts abrasion to be reduced；Sludge agitation device can in case
Only collection mud pit mud caking blocking discharge pipeline；The cleaning shoe cant through some pieces 45 ° assemblings for the mud enters to collect mud pit, then passes through weight
Power or pump are through arranging outside discharge pipeline.
The present invention by the analysis to various mud scrapers, changes original design thinking, ultimately provide a kind of stable, efficient,
Durable, low energy consumption scrape mud thinking and method, compensate for current mud scraper defect.
