[0024] The heavy pressure buffering device comprises a connecting plate 18 arranged on the top of the cab 2, and the surface of the connecting plate 18 is provided with a first buffering plate 19 with an arc-shaped end, the front end of the first buffering plate 19 is inwardly buckled in an arc shape, and the rear end is abutted against a second buffering plate 20 with a corrugated cross section, the connecting part of the first buffering plate 19 and the second buffering plate 20 is concave, and the height of the first buffering plate 19 is higher than the height of the second buffering plate 20. When the heavy objects are stacked on the top of the cab 2, the heavy objects are continuously pressed downward to the cab 2 with the driving of the engineering vehicle. Since the connecting part of the first buffering plate 19 and the second buffering plate 20 is concave, the heavy objects do not directly contact the top of the cab, and the possibility of the impact of the heavy objects on the top of the cab is reduced. Meanwhile, the front end of the first buffering plate 19 is arc-shaped, so that the first buffering plate 19 avoids impacting the top of the cab. With the transition of the first buffering plate 19 downward, the pressure of the heavy objects is transmitted to the second buffering plate 20. Since the second buffering plate 20 has a corrugated cross section, the effect of sufficient energy absorption is achieved, the pressure of the heavy objects on the cab is reduced, and the cab is better protected.

[0025] The top of the cab 2 is provided with a detachable guardrail 21, and the side of the cab 2 is provided with a sliding door 22 for facilitating the driver to enter. The guardrail arranged on the top of the cab 2 prevents the loss of objects from the top of the cab, and the sliding door 22 arranged on the side of the cab 2 facilitates the driver to enter and exit.

[0026] The cab 2 is provided with a lighting lamp and a loudspeaker. The lighting lamp and the loudspeaker facilitate the driver to operate at night and communicate with the outside.

[0027] With the extension of the operation time of the engineering vehicle, the driver needs to look outside to relieve visual fatigue. At this time, the first micro telescopic air cylinder 10 is started, the telescopic rod of the first micro telescopic air cylinder 10 is retracted backward, the first strip-shaped gear seat 8 is driven to move in the horizontal direction, the first strip-shaped gear seat 8 is engaged with the first movable gear 7, and the first movable gear 7 is driven to rotate. With the rotation of the first movable gear 7, the cross connecting frame 6 is subjected to an upward pulling force, the U-shaped connecting frame 11 is driven to move upward by the cross connecting frame 6, the hook plate 12 connected to the middle part of the U-shaped connecting frame 11 is also driven to move upward, the windshield 3 is driven to move upward by the hook plate 12, and the windshield 3 is moved to a position suitable for the driver's line of sight. When the driver relieves visual fatigue, the telescopic rod of the first micro telescopic air cylinder 10 is extended forward, and the above-mentioned action is repeated in reverse, so that the windshield 3 returns to the original state, and the windshield 3 is adjusted freely to adapt to the driver's line of sight.

[0028] Since the windshield 3 is set as a non-fixed type, it can be opened freely, therefore, when the engineering vehicle is driven in rainy weather, if the water collecting facility is not set, the rainwater is easy to enter the driver's cabin 2 through the gap below the windshield 3, causing the damage of the devices in the driver's cabin 2, the water collecting groove 13 is arranged in the operating table 4, the water collecting groove 13 is arranged at the bottom of the windshield 3 at the same time, with the rainwater continuously entering from the gap and falling in the water collecting groove 13, when the rainwater in the water collecting groove 13 accumulates to the set height, the second micro telescopic cylinder 14 is started, the telescopic rod of the second micro telescopic cylinder 14 is extended or retracted, driving the second strip-shaped tooth seat 15 to move, since the second movable gear 16 is in the vertical fixed state at this time, the second strip-shaped tooth seat 15 is limited to rotate around the second movable gear 16, so as to make the U-shaped connecting frame 11 rotate synchronously, the hook plate 12 in the middle of the U-shaped connecting frame 11 pushes the water collecting groove 13, the water collecting groove 13 moves along the inside of the operating table 4, until it is communicated with the poking pipe, the rainwater accumulated in the water collecting groove 13 flows out to the outside of the engineering vehicle body 1 through the poking pipe, avoiding the rainwater entering the inside of the driver's cabin 2, ensuring the safety of the internal devices;

[0029] By using the field of view adjusting device, the windshield 3 is adjusted and the rainwater collection and water removal are set as a whole, not only saving the quantity of required parts, but also ensuring that no rainwater enters the inside cabin after the windshield is adjusted, making the engineering vehicle diversified.

[0030] In conclusion, only the preferred embodiments of the present application are described, which do not limit the scope of the present application, and any equivalent changes and modifications of the shape, structure, features and spirit of the present application within the scope of the claims of the present application should be included in the scope of the claims of the present application.
