Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of hydraulic crawler excavator demonstration device, structure are as shown in figure 1, including control system, body and base 1, the body
It is arranged on base 1, the base 1 has large arm 3, forearm 4, dipper-arm 5 and scraper bowl 6, and the large arm 3 is with being arranged on base 1
On the connection of the axle of column 2, the forearm 4 is connected with the axle of large arm 3, and the dipper-arm 5 is connected with the axle of forearm 4, and the scraper bowl 6 is set
It is connected in the one end of forearm 4 and with the axle of dipper-arm 5, the set-up of control system is on base 1, and the control system includes first
Button 7, the second button 8, the 3rd button 9, first button 7, the second button 8 and the 3rd button 9 are distinguished by rubber tube 13
First piston 10, second piston 11, the 3rd piston 12 are connected with, the first piston 10 is connected with the axle of forearm 4, described second lives
Plug 11 is connected with the axle of large arm 3, and the 3rd piston 12 is connected with the axle of dipper-arm 5.
Wherein,
First button 7 is connected by rubber tube 13 with first piston 10, and control first piston 10 is lifted.
Second button 8 is connected by rubber tube 13 with second piston 11, and control second piston 11 is lifted.
Second button 9 is connected by rubber tube 13 with the 3rd piston 12, and the 3rd piston 12 of control is lifted.
Second piston 11 is connected with large arm 3, controls the lifting of large arm 3.
First piston 10 is connected with forearm 4, controls the lifting of forearm 4.
3rd piston 12 is connected with dipper-arm 5, controls the excavation and rotation of scraper bowl 6.
Using simple and mechanical lever large arm 3 can be made vertically to rotate 45 degree using hydraulic control, forearm 4 can be along vertical
Direction rotates 38 degree, and scraper bowl 6 can vertically rotate 30 degree, realizes excavation, lifting, the function of transferring objects, teaching efficiency
Significantly.
Above-described embodiment, simply preferred embodiment of the present utility model, not for limiting implementation model of the present utility model
Enclose, therefore all equivalent variations done with content described in the utility model claim, all should be included in the utility model right will
Within the scope of asking.
