A heavy balance object is arranged at the back end of the upper rack, is a steel block coated with rust-preventing paint and is provided with four fixing holes distributed in a rectangular shape. A connecting rod, with threads, corresponding to the fixing holes is arranged at the back end of the upper rack. The connecting rod and the balance object are fixed through nuts. A shielding plate is arranged on front shielding glass in the front of the cab. The two ends of the shielding plate are connected with two L-shaped frames through screws. One face of each L-shaped frame is fixed with the lower surface of the shielding plate, and the other face of each L-shaped frame is fixed with the upper end of the cab. The heavy balance object is attractive in appearance and long in service life. The shielding plate is arranged, so that the risk of occurrence of accidents on rainy days and burning sun days is reduced. Shielding cloth is arranged, so that storage and release are convenient, utilization cost is low, and effects are good.

Description

Large excavator

Technical field

The utility model relates to building field, especially relates to a kind of large excavator.

Background technology

Excavator is one of important engineering machinery, and along with the expansion of area of activities, the requirement to excavator in Practical Project is more and more higher.

While work under burning sun, the parts in the excessive easy bad driver's cabin of solarization of the sun raise in driver's cabin fast simultaneously, affect the performance of excavator; In winter, the easy frosting of windshield at night, snowy day, windshield easily froze, and affect the use of excavator, and usually people need to look for cloth to cover windshield in addition, and hide and easily drop, and use inconvenience, look for cloth difficulty temporarily, deposit this cloth and take up room; The current excavator weight equalizer of excavator is all to adopt tandem-driving bogie conventionally, and described tandem-driving bogie is positioned at the rear end of excavator, then adds ore in tandem-driving bogie, scrap iron etc., thereby the weight of increase tandem-driving bogie; This weight equalizer affects the outward appearance of excavator, and tandem-driving bogie gets rusty easily, becomes flexible and come off; And tandem-driving bogie is easily by corrosion such as scrap iron, and service time is short; Tandem-driving bogie dismounting, replacing difficulty, weight equalizer volume is large, takes up room large.Excavator is often in order to work to tight deadlines, also need rainy day excavator to work on, in the time operating in the rain, easily cause windshield fuzzy, and cause front blurred vision, be difficult to operation, and easily there is security incident, and excavator also can be because high light stimulates driver's eyes in the time working, cause driving inconvenience, the risk that increase accident occurs under burning sun.

Utility model content

The utility model, in order to overcome the deficiencies in the prior art, provides a kind of and can make getting a clear view of front in the time that the rainy day operates, and is difficult for occurring the excavator of security incident.

To achieve these goals, the utility model is by the following technical solutions: a kind of large excavator, comprise walking mechanism and upper stand, described upper stand is located at the upper end of walking mechanism, upper stand comprises driver's cabin, motor and the scraper bowl being connected with dipper by swing arm, the rear end of described upper stand is provided with weight equalizer, described weight equalizer is the iron and steel piece that outside scribbles rustproof paint, weight equalizer is provided with the fixing hole of 4 rectangular distributions, upper stand rear end is provided with the threaded connecting rod corresponding with fixing hole, connecting rod and weight equalizer are fixed by nut, the windshield top in described driver's cabin front is provided with shutter, and described shutter two ends are connected by screw two L shaped, and L shaped one side fixed with shutter soffit, and L shaped another side and driver's cabin upper end are fixed, and shutter lower end is provided with water proof lamp.

As preferably, between described two L shaped, connect an axis of rotation, described axis of rotation is provided with a retractable shading cloth, and one end of this axis of rotation passes the portion of holding that L shaped formation grips for hand.

As preferably, described L shaped ferrous materials that scribbles rustproof paint by outside made, and the two ends of L shaped connect by fixed bar.

In sum, the utlity model has following advantage: described weight equalizer good looking appearance, install firmly, difficult drop-off, conveniently, this weight equalizer volume is little, occupies little space, and can make Excavator Appearance more attractive in appearance, is difficult for getting rusty for dismounting, replacing, and service time is long; Above windshield before driver's cabin, driver's cabin arranges shutter, and this shutter not only can obtain driving vision clearly when rainy, and also can reduce the injury of high light to driver's eyes while working under burning sun, thereby reduces the risk that has an accident; This shading cloth is set, while work, can puts down shading cloth under burning sun, prevent the parts in bad driver's cabin of the excessive solarization of the sun, play cooling effect simultaneously, prevent excess Temperature in driver's cabin, affect the performance of excavator; In winter, put down shading cloth night and can prevent windshield frosting, can prevent that in snowy day glass from freezing, and this shading cloth is simple in structure, folding and unfolding is convenient, and use cost is low, effective, does not take up space.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.

As shown in Figure 1; a kind of large excavator; comprise walking mechanism 2 and upper stand 3; described upper stand 3 is located at the upper end of walking mechanism 2; upper stand 3 comprises driver's cabin 1, motor and the scraper bowl 4 being connected with dipper 42 by swing arm 41; the rear end of described upper stand 3 is provided with weight equalizer 31; described weight equalizer 31 is the outside iron and steel piece that scribbles rustproof paint; weight equalizer 31 is provided with the fixing hole of 4 rectangular distributions; upper stand 3 rear ends are provided with the threaded connecting rod corresponding with fixing hole, and connecting rod and weight equalizer are fixed by nut; Described flat horizontal weight is set to multiple, can carry out as required suitable increase and decrease, and weight equalizer good looking appearance, installs firmly, difficult drop-off, conveniently, this weight equalizer volume is little, occupies little space for dismounting, replacing, can make Excavator Appearance more attractive in appearance, be difficult for getting rusty, service time is long; The windshield top in described driver's cabin 1 front is provided with shutter 12, described shutter 12 two ends are connected by screw two L shaped 5, L shaped 5 one side fixed with shutter 12 soffits, and L shaped 5 another side and driver's cabin 1 upper end are fixed, and shutter 12 lower ends are provided with water proof lamp 11; This shutter is set, and while raining, this shutter 12 can effectively avoid rainwater to drop on the windshield before driver's cabin 1, and then makes driver can obtain driving vision clearly, the risk of reduction accident; And also can reduce the injury of high light to driver's eyes while working under burning sun, this setting simple in structure, realizes easily.
