Description
Technical field: the present invention relates to a kind of equipment of removing contamination, especially a kind of device of realizing a complete set of mechanization of channel cleanout operation.
Background technology: river course and pond desilting scrubbing, for concerning a great problem of town and country environmental protection and residents ' health.Mostly the traditional dredging method of China is " sea of faces's formula " construction of spade, car, pump integration of operation; Though the part mechanized is wherein also arranged; But realize far away from the system mechanization of the overall process of excavating, be transported to the entrucking outward transport, thereby not only desilting efficiency data is low, labour intensity is big; And abominable because of operating environment, it is healthy greatly to have influenced the constructor.
Summary of the invention: in view of this, task of the present invention just is to design a kind of the complete sets of equipment that can realize the mechanization of dredging operation overall process, and is thoroughly clean to reach desilting; Operating efficiency is high; Personnel selection is few, and the requirement that the duration is short fundamentally improves the backward situation of China's desilting work.
This task is achieved in that mining machine for dredging is carried by digging assembly, secondary, three grades, level Four and the engineering transport vehicle is formed.Mining machine for dredging drives river course bottom into and carries out digging operation, the material of extraction by screw propulsion after, send into the one, two, three, four conveyer, the engineering truck outward transport on the bank of packing at last.Conveyings at different levels all have self-powered, automatic carrying-off, automatic lifting, automatic angle adjusting function, thereby realize the mechanization of operation overall process.
Described this machine digging assembly is formed by taking off thing device, shovel thing device, spiral propeller and primary conveyor.
Taking off the thing device is that a usefulness bolt connects the parts that constituted with scraper box and conveyer belt, by fluid motor-driven.Take off the thing device material is grilled into spiral propeller, deliver to primary conveyor; Take off the thing device take off lift voluntarily to the riverbed after, bed chipping forward falls to taking off thing once more then gradually along the river, gets into next circulation.Take off the thing device and take off beyond the region of objective existence, can go up and down voluntarily except that rotation.Above-mentioned four part collaborative works, segmentation is opened up pick and is progressively advanced.
Shovel thing device comprises spear and shovels body up and down, shovels body up and down with spiral propeller links together, and passes through bracing frame and hydraulic cylinder is controlled, and together with taking off the thing device, does elevating movement, thus the integral elevating of real cutting arrangement.
Spiral propeller is made up of spiral, arc groove and support, and helical axis is equipped with at its center, and leading section is row's thing end, and rearward end is equipped with hydraulic motor, drives by motor, promotes material and does the helical form conveying.
Primary conveyor is made up of conveyer belt, hydraulic motor and the frame of the drive roll that synchronous pulley is housed, driven voller, band watt bucket, and its effect is the material that is transported by spiral propeller to be done to promote carry, most the two-stage conveying machine.
One-level is carried to tilt-lift and is carried operation, and the bottom is lower, is positioned at the below of helical feed, and the scraper box of back and forth advancing is housed on it.Because band and synchronous pulley structure convey materials are synchronously adopted in the condition of work requirement.One-level is carried the power of adapted, adopts low speed high torque hydraulic motor as power source.
Two-stage conveying is accepted the material that one-level is carried.But vertical and horizontal are advanced on request, introduce wheel by the front and back of the portraitlandscape of installing, and realize independent-lifting; Advance separately, thereby accomplish in length and breadth to advancing and transposition, and the driver behavior platform through installing in this machine one side; Adopt fluid motor-driven, regulate the two ends height.Two-stage conveying is that a kind of level is carried operation.
Carry the support body below to be provided with rotating shaft, support body is turned to for three grades.This rotating shaft also is the following strong point, turns to the inclination angle size by the control of posture adjustment oil cylinder, according to job requirement self-regulated inclination angle.The support body opposite side is provided with support cylinder, increases the stability of body.Fluid motor-driven is also adopted in walking and conveying running, the four-wheel walking.Wheel body adopts anti-pulley, band and synchronous pulley and watt bucket structure synchronously.Three grades of conveyings are vertical the transmission.
Level Four is carried, and except that pulley in the air, its structure is identical with three grades of conveyings, but the method for operation is for tilting to transmit.
The present invention is installed on the shovel fortune arm of loader by taking off this machine body of work part that thing device, spiral propeller and shovel thing device are constituted, and power is provided by the motor and the hydraulic oil pump of loader.The power source that three grades of level Four of secondary are carried is provided by bank packaged type generating set.The electric power that the vehicular power generation unit sends gives two, three, the level Four conveyer, on above-mentioned three machines motor is housed, to drive hydraulic oil pump work.
Adopt this machine of technique scheme design, owing to be a complete set of equipment, mechanization degree is high, and personnel selection is few, and per tour only needs 5---and 10 people operation, workload reaches per hour adopts silt 20m
3---30cm
3, can work continuously in 24 hours.The mud of the extraction soil of can reclaiming makes low-lying floods ground, abandoned land, the useless hole of kiln and discarded pond etc. become good farmland in blocks.This is very useful for the modernization construction that improves environment, improves the quality of living, accelerates town and country.The product blank of China in the desilting equipment field filled up in this design, has great economic worth and social benefit.
