Abstract
The utility model relates to a hydraulic control enforced unloading soil device for pulling laser plat land level scraper, belonging to the technical field of laser carrying scraper, which comprises a discharging soil board, a pulling tackle, an apron, a soil-blading oil cylinder, an apron oil cylinder and a quick joystick in a cab. The discharging soil board is hinged with the pulling tackle by a pin shaft, the quick joystick is connected with an oil cylinder through an oil channel, and the apron oil cylinder is connected with a back wheel carrier; the two ends of the soil-blading oil cylinder are respectively connected with the pulling tackle and the back wheel carrier, and the soil-blading oil cylinder is connected with the apron oil cylinder in parallel. The features of the hydraulic control inforced unloading soil device for pulling laser land levelling scraper are that the telescoping of the doze oil cylinder drives the advance and retreat of the tackle, and meanwhile, the descent and the ascend of the apron driven by the telescoping of the apron oil cylinder can be realized. The utility model has the advantage of simple operation; the enforced soil discharging of the scraper and the synchronization of the opening and the oil discharging of the apron can be realized; the soil discharging volume can be controlled, being used for the trade of machines for carrying soil and stone, flat land machines, machines for carrying and scraping, etc.
Description
Technical field
The utility model relates to a kind of cubic metre of earth of conveying arrangement, especially a kind of hydraulic control inforced unloading soil device that drags the formula laser land levelling scraper.
Background technology
At present, the general unloading device that drags the formula laser land levelling scraper on the market, because soil-shifting oil cylinder and sluice gate oil cylinder can not simultaneously operatings, ejector dozer and sluice gate can not be synchronized with the movement, make soil-shifting level land work process operation complexity, and can not finish surpass that filling out of maximum earthwork dug, work such as transportation and topsoil stripping, when carrying out smooth operation, can not control the size of discharging earth volume, therefore increase the workload on the meticulous level land of land leveller.
Summary of the invention
The utility model provides a kind of hydraulic control inforced unloading soil device that drags the formula laser land levelling scraper simple to operate for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of hydraulic control inforced unloading soil device that drags the formula laser land levelling scraper, by soil-dumping plate, constitute with hinged sliding car, sluice gate, soil-shifting oil cylinder, sluice gate oil cylinder of soil-dumping plate and the quick change control stick of controlling two oil cylinders, the sluice gate oil cylinder is connected with rear wheel frame, the two ends of soil-shifting oil cylinder link to each other with rear wheel frame with the sliding car respectively, soil-shifting oil cylinder and sluice gate oil cylinder each and connect two, two soil-shifting oil cylinder rodless cavity parallel connected end are serially connected with one way valve, and the one way valve input also connects the rod chamber of sluice gate oil cylinder; The rodless cavity of sluice gate oil cylinder is serially connected with one way valve, and the input of one way valve also connects the rod chamber that string has the soil-shifting oil cylinder of choke valve.
Advantage and the good effect that the utlity model has are: since the soil-shifting oil cylinder rodless cavity by one way valve and sluice gate oil cylinder rod chamber and connect, the rodless cavity of sluice gate oil cylinder is by one way valve and soil-shifting cylinder rod chamber and connect, therefore make the interlock of soil-dumping plate and sluice gate, can finish a large amount of cubic meters carrying, saved before the prior art equipment level land by loader or the earlier thick level land of level land shovel, used again and drag the formula level land to shovel the expense and the time on smart level land, and can thoroughly remove the soil that is adhered on the bucket end and the headwall, especially during big native of shovel fortune clay and water content, it is better to unload native effect.When forcing to unload native process, the sluice gate oil cylinder carries out opposite action with the soil-shifting oil cylinder, thereby has controlled the earth volume of discharging, has reduced smart flat workload.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model soil-shifting oil cylinder and sluice gate oil cylinder connection diagram.
Among the figure: 1-rear wheel frame, 2-trailing wheel, 3-sliding car, 4-bearing pin, the 5-soil-dumping plate, 6-laser instrument, 7-sluice gate, 8-hitch frame, the 9-oil circuit, 10-scraper bowl, 11-sluice gate oil cylinder, the 12-side shield, 13-bottom roller, 14-side wheel, 15-soil-shifting oil cylinder, 16-choke valve, 17-one way valve, the 18-control stick, 19-oil pump, 20-fuel tank.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the hinged hitch frame 8 of the front end of rear wheel frame 1, the rear wheel frame central bottom is installed scraper bowl 10, and trailing wheel 2 is installed at the rear wheel frame rear portion.Hinged two level soil-shifting oil cylinders 15 on the rear wheel frame, the tailpiece of the piston rod of two soil-shifting oil cylinders is hinged with soil-dumping plate 5, the soil-dumping plate upper end is equipped with bottom roller 13 and side wheel 14 by bearing pin 4 hinged sliding cars 3 on the sliding car, the sliding car is moved forward and backward in scraper bowl by its side wheel and bottom roller.At rear wheel frame middle upper portion installation side baffle plate 12, hinged sluice gate oil cylinder 11 on the side shield, the tailpiece of the piston rod of sluice gate oil cylinder is equipped with sluice gate 7.On rear wheel frame and hitch frame, also be separately installed with the oil circuit 9 of laser instrument 6 and each oil cylinder of connection.
Operating principle:
As depicted in figs. 1 and 2, when forcing to unload soil, 18 actions of oil cylinder quick change control stick, make the rear portion that flows into the soil-shifting oil cylinder from the pressure oil part of oil pump 19 inputs by one way valve 17, the reach of promotion piston, soil-shifting cylinder rod chamber pressure oil flows back to fuel tank 20 by choke valve 16, makes soil-dumping plate 5 carry out forced action type and unloads soil.Another part flows into the top of sluice gate oil cylinder 11 by oil duct, the promotion piston moves down, oil return is flowed back to fuel tank by the one way valve 17 of sluice gate oil cylinder serial connection, make sluice gate 7 progressively closed, in the closed gradually process of sluice gate, sluice gate can effectively be controlled and unload the soil amount, when soil-shifting oil cylinder 15 reaches peak discharge, soil in the scraper bowl 10 is all discharged, and this moment, sluice gate was closed.The oil return of soil-shifting oil cylinder and sluice gate oil cylinder is flowed back to fuel tank 20 respectively from oil return line.Realize that simultaneously contracting of sluice gate oil cylinder stretch decline and the rising that drives sluice gate.Realize filling and leading up of surface concave over the ground.
When shoveling soil, oil cylinder quick change control stick action makes from the pressure oil part of oil pump input and flows into the bottom of sluice gate oil cylinder by one way valve, promotes to move on the piston, and sluice gate is upwardly opened.Another part promotes to move behind the piston by the front portion of choke valve 16 inflow soil-shifting oil cylinders, and ejector dozer is moved backward.When the sluice gate oil cylinder reached peak discharge, sluice gate all opened, and this moment, ejector dozer was got back to the position before forcing to bulldoze.Realization is to the carrying of evening out of protruding of ground surface and earth volume.
