The specific embodiment

Understand for technical characterictic, purpose and effect to the utility model have more clearly, contrast the specific embodiment of description of drawings the utility model, but it is merely preferred embodiment, is not used for limiting the essential scope of the utility model at present.

Please combine with reference to figure 1 and Fig. 2; Wherein Fig. 1 is the anti-junk apparatus structure scheme drawing of the utility model operator's compartment; Fig. 2 is installed on the operator's compartment scheme drawing for the anti-junk device of the utility model operator's compartment, and as shown in the figure, the anti-junk device 100 of the utility model is fixedly set in the top of operator's compartment 200; Anti-junk device 100 mainly includes: shield plate 1 is fixedly arranged on the top of operator's compartment; Shield plate 1 is provided with reinforced rib 2, is used to strengthen the intensity of shield plate 1.

Shield plate 1 tiling is fixedly arranged on the top of operator's compartment, in case protect operator's compartment and in-to-in operator thereof, and in the present embodiment; The shape of shield plate 1 is similar with the operator's compartment top; The area at area and operator's compartment top is suitable, perhaps, and slightly greater than the top of operator's compartment; Shield plate 1 just can hide operator's compartment completely like this, thus the safety of better protection operator's compartment.The both sides of shield plate 1 bending downwards and form two installation portions 11; Thereby make whole protection cover plate 1 approximately be down " U " shape; Shield plate 1 promptly is fixed in the top of operator's compartment through installation portion 11, affixed mode is unrestricted, can adopt common riveted and fixed mode.Shield plate 1 its end near the drive window of operator's compartment is provided with a plurality of grid hole 12, and a plurality of grid hole 12 can be arranged in an array, and is as shown in the figure, and the purpose that is provided with in grid hole 12 mainly is the daylighting that is beneficial to operator's compartment, and the visual field that can enlarge the operator to a certain extent.

Shield plate 1 is provided with the reinforced rib 2 of strengthening its intensity; In the present embodiment; Reinforced rib attaches the bottom side be arranged at shield plate 1, is arranged in the inner space that installation portion 11 that shield plate 1 and both sides form is surrounded, and the two ends of reinforced rib 2 are connected to the installation portion 11 of both sides; The muscle body portion of reinforced rib 2 is attached at the bottom side of shield plate 1; Perhaps also can be with shield plate 1 one-body moldedly, between the horizontal installation portion that is arranged at both sides 11 of reinforced rib 2, thereby but actv. is strengthened the intensity of shield plate 1.Reinforced rib 2 that quantity is set is unrestricted, the quantity that can confirm to be provided with reinforced rib according to the size and the shape of shield plate 1 is in the present embodiment; The bottom side of shield plate 1 is provided with many reinforced ribs 2, and many reinforced ribs 2 laterally arrange, and the two ends of each reinforced rib all are connected in the installation portion 11 of both sides; And the muscle body portion of reinforced rib all attaches the bottom side that is arranged at shield plate; So, the intensity of shield plate 1 will improve greatly, obtains higher safety.But the set-up mode of reinforced rib is not as restriction; Those skilled in the art should carry out Simple deduction according to the above embodiments; Can learn that for example reinforced rib also can be arranged at the upside of protecting cover, its set-up mode also can be to report to the leadship after accomplishing a task and is provided with or the like; The specific embodiment is well known to those skilled in the art, just repeats no more at this.

Below in conjunction with the simple application that the anti-junk device of operator's compartment of the utility model is described with reference to above-mentioned each figure; As shown in the figure; Shield plate 1 is fixed in the top of operator's compartment 200 through installation portion 11, and the top riveted and fixed of installation portion 11 and operator's compartment 200 firmly connects to obtain failure-free.And many reinforced ribs that laterally laterally arrange 2 between shield plate 1 bottom side, two installation portions 11 with the intensity that increases whole anti-junk device greatly, think that operator's compartment and operator provide safety.In addition, at shield plate 1 front end, just shield plate 1 offers a plurality of grid hole near an end of operator's compartment drive window, and the daylighting and the operator that are beneficial to operator's compartment widen the vision.

The above is merely the schematic specific embodiment of the utility model, is not in order to limit the scope of the utility model.Any those skilled in the art, equivalent variations of under the prerequisite of design that does not break away from the utility model and principle, having done and modification all should belong to the scope that the utility model is protected.
