[0017] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0018] See also Figures 1 to 3The utility model provides a steep slope protection backfill construction device, including a vehicle body 11, a belt conveyor and a pressing plate 6. The vehicle body 11 can be an electric or fuel engineering vehicle in the prior art. A slider 8 and a hydraulic cylinder 7 are slidably provided on the rear chassis of the vehicle body 11 from front to back in sequence. The lower end of the belt conveyor is hinged to the upper surface of the slider 8, the upper end of the belt conveyor is hinged to the upper end surface of the pressing plate 6, the middle part of the front side of the pressing plate 6 is hinged to the telescopic end of the hydraulic cylinder 7, the lower end of the pressing plate 6 is hinged to the rear end of the rear chassis of the vehicle body 11, and a baffle 12 is slidably inserted at the lower end of the pressing plate 6, and the baffle 12 can slide in the lower end of the pressing plate 6 along a direction perpendicular to the pressing plate 6;

[0019] When the utility model needs to adjust the backfill angle, the hydraulic cylinder 7 drives the pressing plate 6 to swing at the rear end of the vehicle body 11. When the hydraulic cylinder 7 is extended, the hydraulic cylinder 7 drives the pressing plate 6 to swing counterclockwise, so that the inclination angle of the pressing plate 6 is reduced. During this process, the pressing plate 6 drives the upper end of the belt conveyor to move backward and downward, and the upper and lower ends of the belt conveyor swing adaptively on the upper end of the pressing plate 6 and the slider 8 respectively, and the lower end of the belt conveyor drives the slider 8 to slide backward; when the hydraulic cylinder 7 is shortened, the hydraulic cylinder 7 drives the pressing plate 6 to swing clockwise, so that the inclination angle of the pressing plate 6 is increased. During this process, the pressing plate 6 drives the upper end of the belt conveyor to move forward and upward, and the upper and lower ends of the belt conveyor swing adaptively on the upper end of the pressing plate 6 and the slider 8 respectively, and the lower end of the belt conveyor drives the slider 8 to slide forward, which provides a suitable degree of freedom of movement for the overall motion structure. A good coordinated movement between the mechanisms is achieved, so that the pressure plate 6 can be driven by the hydraulic cylinder 7 to present different angles to be suitable for backfilling slope protection at different angles; after adjusting the angle of the pressure plate 6, the pressure plate 6 is driven to move to a suitable distance from the slope by driving the vehicle body 11 backward, and the rear end of the baffle plate 12 is adjusted to contact the original slope surface to prevent the backfilled soil from leaking from the bottom between the pressure plate 6 and the slope surface. After the soil is continuously thrown onto the lower end of the belt conveyor, the belt conveyor is used to transport the soil from bottom to top between the pressure plate 6 and the slope surface for backfilling. After the backfilling is completed, the vehicle body 11 is used to drive the pressure plate 6 to move backward, so that the pressure plate 6 compacts the new soil on the slope surface at one time for compaction. In this process, the slope pushes the baffle plate 12 to slide forward in the lower end of the pressure plate 6 until the compaction is completed. The compaction efficiency is high and it is suitable for backfilling slope protection with different slopes.

[0020] Preferably, one end of the baffle 12 close to the vehicle body 11 is connected to the plug plate through a plurality of springs 13 , and the tension of the springs 13 is used to maintain a sufficient adjustment distance between the rear end face of the baffle 12 and the rear side face of the pressure plate 6 .

[0021] When adjusting the distance between the pressure plate 6 and the slope, the vehicle body 11 drives the pressure plate 6 to move backward, and the pressure plate 6 will first drive the rear end surface of the baffle 12 to contact the slope and stretch the spring 13; during the tamping process, the baffle 12 is pushed by the slope, causing the baffle 12 to slide forward on the pressure plate 6 and continue to stretch the spring 13. After the tamping is completed, the vehicle body 11 drives the pressure plate 6 to move forward, and under the action of the rebound force of the spring 13, the baffle 12 is driven to slide backward in the pressure plate 6 for automatic reset. There is no need to manually adjust the rear end of the baffle 12 to contact the slope after adjusting the distance between the pressure plate 6 and the slope each time.

[0022] Preferably, a connecting plate 14 is fixedly provided on one end of the plug plate close to the vehicle body 11, and a plurality of springs 13 are connected at intervals between the connecting plate 14 and the opposite surfaces of the pressure plate 6. Specifically, the two ends of the spring 13 are respectively connected to the opposite surfaces of the connecting plate 14 and the pressure plate 6.

[0023] Preferably, a slide groove 10 is provided on the rear chassis of the vehicle body 11, and the slider 8 is arranged in the slide groove 10. The cross-sections of the slider 8 and the slide groove 10 are both T-shaped structures, so that the slider 8 can only slide on the vehicle body 11 but cannot fall off from the vehicle body 11.

[0024] Preferably, the belt conveyor includes a frame 5, a motorized roller 3, a driven roller 9 and a conveyor belt 4. The upper and lower ends of the frame 5 are respectively hinged to the upper end of the pressure plate 6 and the upper surface of the slider 8. The motorized roller 3 and the driven roller 9 are respectively arranged at the two ends of the frame 5. The conveyor belt 4 is connected between the motorized roller 3 and the driven roller 9. A plurality of material baffle plates 2 are arranged at intervals on the conveyor belt 4.

[0025] Under the action of the conveyor belt 4, the motorized roller 3 can drive the driven roller 9 to rotate on the frame 5 through the conveyor belt 4, so that the conveyor belt 4 is transmitted between the motorized roller 3 and the driven roller 9, and the conveyor belt 4 drives multiple baffle plates 2 to move up and down in a cycle. After the soil is thrown onto the lower side of the conveyor belt 4, the baffle plates 2 can be used to continuously transport the soil upward between the pressure plate 6 and the slope.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
