Abstract
A kind of scraper practice teaching machine, scraper bowl bottom are flexibly connected with one end of large arm, and the other end of large arm is fixed in frame, and elevating ram is arranged in frame, and the free end of elevating ram is connected with large arm；The free end of dump ram connects with scraper bowl side, and dump ram is fixed in frame；Frame is arranged on the slide rail of base, and the both ends of advance and retreat oil cylinder are connected on frame and base；Lifting, tipping bucket, advance and retreat oil cylinder are connected by choke valve, directional control valve, overflow valve with fuel tank, and by motor, oil pump control.The present invention by motor driven oil pump by hydraulic drive, drive cylinder, and is moved by control stick controlling organization by quadric chain, realizes the shovel handling operation of scraper scraper bowl.It is applied in teaching practice, student can obtain the effect of on-the-spot teaching without using building-site, so as to both save the expense that teachers and students go building-site to impart knowledge to students, solve the predicament that real engineering machinery is not easy to student's dismounting again.
Description
Technical field
The present invention relates to teaching appliance, especially a kind of scraper practice teaching machine.
Background technology
As our countries increasingly pay attention to vocational education, major specially professional colleges are real to the teaching needed for vocational education
It is also more and more urgent to instruct the demand of equipment, and in our existing vocational instruction electromechanical equipments, to being widely used in engineering machinery
With the practice-training teaching of the scraper in mining machinery field, lack a kind of convenient and practical, small-sized and for interior practice teaching and set
It is standby.It is vivid and this equipment will have convenient teaching, the features such as being easy to student to dismantle.
The content of the invention
Conveniently imparted knowledge to students it is an object of the invention to provide one kind, be vivid, being easy to student to dismantle, teachers and students can be saved and go work
The scraper practice teaching machine of ground on-the-spot teaching expense.
The scraper practice teaching machine of the present invention, including base, scraper bowl, elevating ram, frame, dump ram, motor, oil
Pump, fuel tank, advance and retreat oil cylinder, motor, oil pump, fuel tank are arranged on base, it is characterised in that scraper bowl bottom and one end of large arm are lived
Dynamic connection, the other end of large arm are fixed in frame by bearing pin, and elevating ram is arranged in frame, the free end of elevating ram
It is connected with large arm；The free end of dump ram connects with scraper bowl side, and dump ram is fixed in frame；Frame is arranged on base
Slide rail on, can be moved forward and backward along slide rail, the both ends of advance and retreat oil cylinder be connected to frame with base；Elevating ram, tipping bucket
Oil cylinder, advance and retreat oil cylinder are connected by choke valve, directional control valve, overflow valve with fuel tank, and by motor, oil pump control.
The scraper practice teaching machine of the present invention, by quadric chain, by motor driven oil pump by hydraulic drive, drive
Dynamic elevating ram, dump ram, advance and retreat oil cylinder, and moved in three directions by control stick controlling organization, realize shovel
Transport the shovel handling operation of mechanical shovel bucket.The machine is applied in the teaching practice of vocational education, student can not use building-site
Effect with regard to obtaining on-the-spot teaching, so as to both save the expense that teachers and students go building-site to impart knowledge to students, solves real engineering machine again
Tool is not easy to the predicament of student's dismounting.Student by the equipment laboratory demonstration, it becomes possible to understand machine vividly
The operation principle of tool mechanism and hydraulic technique, both building-site operation can be simulated, again by operating scraper practice teaching machine
Its machine components and Hydraulic Elements can be easily dismounted in laboratory, so as to reach satisfied teaching purpose.
