Excavator claims again excavation machinery, is to excavate with scraper bowl to be higher or lower than the material that holds machine side, and the haulage vehicle or unload civil machinery to rickyard of packing into.The material that excavates mainly is the Soil and Rock behind soil, coal, silt and the pre-pine of process.From the in recent years development of engineering machinery, the development of excavator is relatively very fast, and excavator is as one of topmost engineering machinery type in the engineering construction, and it has played huge effect.At present, common excavator generally only has single armed, and when the operating mode that needs are operated on a large scale operated, the working site need to be equipped with many excavators, and the manpower and materials cost is higher, and digging efficiency is also lower.And in the narrower situation in working site, it is larger that many excavators take up room, and causes operation inconvenience.Therefore, study a kind of can using manpower and material resources sparingly, and can to save the excavator that takes up room be that realistic meaning is relatively arranged.
Summary of the invention
For the defective that exists in the above-mentioned prior art or deficiency, the purpose of this utility model is, a kind of two arm excavator that digs is provided, this excavator has been broken through the limitation that traditional excavator only has single armed, increase a same rotation at traditional single armed excavator and dig arm, this excavator adopts both arms work, reduce rotational time, improve digging efficiency, thereby reduced cost of manufacture, manpower and transport resource and energy consumption improve the quality of production, greatly improved operating efficiency, thereby realize the expection of energy-saving and emission-reduction, realize effective utilization of the energy, be highly suitable for the operating mode that need to operate on a large scale.
To achieve these goals, the utility model adopts following technical solution:
A kind ofly two dig the arm excavator, comprise that driver's cabin, center support crawler belt and two dig arm, described two dig arm respectively symmetry be installed in the driver's cabin both sides; The center support crawler belt is installed between two crawler belts of chassis of dredging machine below; Described rotating disk is connected with mainframe box control centre and drives rotation by it;
The both sides of described center support crawler belt are respectively arranged with lifting hydraulic cylinder, two groups of limit guide rail and two limited rollers; Wherein, described lifting hydraulic cylinder is positioned at center support crawler belt middle part, and the lifting hydraulic cylinder upper end is connected with chassis of dredging machine, and the track beam of lower end and center support crawler belt is connected; Two groups of limit guide rail symmetries are installed in the both sides of lifting hydraulic cylinder, and every group of limit guide rail comprises two parallel limit guide rail, and upper end and the chassis of dredging machine of limit guide rail are connected; Installing one between every group of limit guide rail can be along the limited roller of its scroll-up/down, and limited roller is fixed on the track beam; Lifting hydraulic cylinder is connected with mainframe box control centre and by its driving.
The utility model also comprises following other technologies feature:
Described two are dug the rotating disk of arm by the bottom and are installed on the excavator, and described rotating disk can drive and dig arm and rotate in 360 degree scopes of horizontal plane.
Be equipped with two in the described driver's cabin and dig arm transfer control lever, the described arm transfer control lever that digs connects mainframe box control centre.
In the described driver's cabin rotary seat is installed.
Described limited roller is fixed on the track beam by the roller pin.
The beneficial effects of the utility model are as follows:
1, digs the arm below and be designed with rotating disk, conveniently dig arm optional turning work in 360 degree scopes.
2, be designed with the center support crawler belt in the middle of two crawler belts below excavator, efficiently solve the weight support problem in the excavator course of work after arm is dug in one of common excavator increase, the center support crawler belt not only can support walking when heavy duty, can also pack up to reduce lost motion when underloading.
3, the center support crawler belt directly is not connected with chassis of dredging machine, its support and contraction all are by the parked of lifting hydraulic cylinder and retrieve to realize, the front and back end of center support crawler belt is limited by limit guide rail and two limited rollers respectively, so that the center support crawler belt remains vertical direction and can not rock back and forth when promoting or fall, increase its stability.
4, dig the arm control lever and be positioned at driver's cabin and be respectively applied to operate two and dig arm, easy to operate.
5, drive the rotary seats that interior design can 360 degree, make things convenient for the operating grip of driver's operation all directions.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural representation of center support crawler belt.
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The specific embodiment
As depicted in figs. 1 and 2, two arm excavator that digs of the present utility model, comprise that driver's cabin 1, center support crawler belt 4 and two dig arm 2, described two dig arm 2 respectively symmetry be installed in driver's cabin 1 both sides, and two are dug the rotating disk 3 of arm 2 by the bottom and are installed on the excavator, and described rotating disk 3 can drive and dig arm 2 and rotate in 360 degree scopes of horizontal plane; Center support crawler belt 4 is installed between two crawler belts of chassis of dredging machine below; Described rotating disk 3 links to each other with mainframe box control centre respectively with center support crawler belt 4, and rotating disk 3 is connected with mainframe box control centre and drives rotation by it.
