Abstract
The invention belongs to an excavator, and in particular relates to an excavator scraper bucket. The excavator scraper bucket comprises an excavator scraper bucket body with a scraper head and a scraper arm, and is characterized in that the scraper head is provided with a drill rod. The excavator scraper bucket has the advantages of ensuring that an excavator can work efficiently even under the condition that goods, such as coal, soil, sand, stone and the like, are frozen in winter, greatly prolonging the service life of the scraper arm of the excavator, along with simple operation.
Description
Technical field
The invention belongs to excavator, relate in particular to a kind of power shovel.
Background technology
Excavator is a large-scale apparatus commonly used at present, power shovel is as one of vitals of excavator, be directly connected to the application life of excavator integral body its application life, because northern wintry weather is colder, the goods that needs loading and unloading is (as coal, soil, sandstone etc.) usually freeze because of low temperature, because present power shovel mostly is parallel shovel, lifting surface area is big, the active force that feeds back to thus on the excavator working arm is also very big, the goods shovel could be transported so usually need to strengthen the power of excavator working arm, has not only wasted the energy but also has caused the damage of working arm easily.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, and a kind of power shovel is provided, also can work efficiently under the situation that goods freezes in the winter time, can not cause the damage of shovel arm simultaneously.
The present invention for achieving the above object, by the following technical solutions: a kind of power shovel, comprise the power shovel body that has shovel head and shovel arm, it is characterized in that: described shovel is provided with drill steel.
Described drill steel is connected with the shovel head.
Described drill steel is connected with oil cylinder piston on the oil cylinder that is fixed in shovel arm inside by trace.
Described trace two ends are universal axial plane or sphere axial plane.
Described shovel head is provided with and the protective sleeve of oil cylinder piston on same axis, and described drill steel and protective sleeve are slidingly connected.
Be connected with the equalizing valve that is communicated with hydraulic control system on the described oil cylinder.
Beneficial effect: guaranteed that excavator also can work efficiently under the situation that goods in winter (as coal, soil, sandstone etc.) freezes, simple to operate, the application life of having improved the digger shovel arm greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a upward view of the present invention.
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As Fig. 1, shown in 2, embodiment one, and a kind of power shovel comprises the power shovel body that has shovel 1 and shovel arm 2, and described shovel 1 is provided with drill steel 3.Described drill steel 3 is connected with shovel 1.Described drill steel 3 is fixed on the shovel head by bolt and nut.During work, shovel head can use as common shovel head, if with to thicker frost zone, drill steel 3 is installed in shovels on 1 and can use.Embodiment two, and described drill steel 3 is connected with oil cylinder piston 4-1 on the oil cylinder 4 that is fixed in shovel arm 2 inside by trace 5.In order to overcome the out of line problem of piston, trace and drill steel; described trace 5 two ends are universal axial plane or sphere axial plane; be similarly universal axial plane or sphere axial plane with universal axial plane or the corresponding piston end of sphere axial plane and drill steel end; described shovel 1 is provided with the protective sleeve 6 on same axis with oil cylinder piston 4-1, and protective sleeve 6 is fixed on the shovel 1.Described drill steel 3 is slidingly connected with protective sleeve 6.In order to protect drill steel and oil cylinder, be connected with the equalizing valve 7 that is communicated with hydraulic control system on the described oil cylinder 4.Equalizing valve automatic deloading when drill steel pressure surpasses 6MPa.At the other foot valve that two four-ways that are connected with pioneer pump are installed of driver's cabin throttle; one end of foot valve is connected with equalizing valve; during work; if run into thicker frost zone, step on foot valve, drill steel stretches out from protective sleeve; earlier frost zone is pulverized again and load and unload with scraper bowl; when not needing drill steel, unclamp foot valve, drill steel promptly is recovered in the protective sleeve.Not needing under the situation of drill steel for a long time, also drill steel and protective sleeve can be unloaded from scraper bowl.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
