[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment

[0022] Please refer to Figures 1 to 3 , which is an embodiment of the present utility model. This embodiment provides a technical solution: A central median gravel blind ditch construction device includes

[0023] Dump truck 1, and a discharge opening 11 is provided at the rear end of the dump truck 1. During actual construction, the dump truck 1 travels on a road surface higher than the blind ditch of the central divider, and the bottom end of the inclined gravel chute 3 extends down into the blind ditch on one side of the road surface;

[0024] The inclined gravel chute 3 is bolted to the rear end of the dump truck 1, and the bottom end of the inclined gravel chute 3 extends into the blind ditch, and can continuously send gravel into the blind ditch during the driving of the dump truck 1;

[0025] The permeable geotextile covering device 4 installed at the bottom end of the inclined gravel chute 3;

[0026] The lifting clamping plate structure 2 installed on the rear end surface of the dump truck 1 and corresponding to the discharge opening 11 in position.

[0027] Among them, the lifting clamping plate structure 2 includes a driving oil cylinder 21 installed on the rear end surface of the dump truck 1, a push plate 22 slidably installed on the rear end surface of the dump truck 1 and connected to the piston rod at the bottom end of the driving oil cylinder 21, and a discharge opening 11 fixed to the bottom of the push plate 22 and covering the discharge opening 11. In the later stage, by driving the driving oil cylinder 21, the piston rod at the bottom end of the driving oil cylinder 21 can drive the push plate 22 and the movable clamping plate 23 to lift, so as to achieve the purpose of adjusting the size of the outlet of the discharge opening 11 and the purpose of adjusting the discharge speed, meeting different construction requirements.

[0028] Among them, the top end of the driving oil cylinder 21 is fixed to the rear end surface of the dump truck 1 by bolts, realizing the stable installation of the driving oil cylinder 21.

[0029] Among them, a guiding slider is welded and fixed to one side of the push plate 22, and a guiding chute corresponding to the guiding slider is provided on the rear end surface of the dump truck 1, and the guiding slider slides in the guiding chute, so that the push plate 22 can slide up and down stably on the rear end surface of the dump truck 1.

[0030] Among them, a feeding notch 31 corresponding to the discharge opening 11 is provided on one side of the top end of the inclined gravel chute 3, so that the gravel in the dump truck 1 can smoothly enter the inclined gravel chute 3 through the feeding notch 31 after being discharged through the discharge opening 11, and finally be dumped to the lower blind ditch from the bottom end of the inclined gravel chute 3.

[0031] Among them, a scraping plate 32 is further fixed on the bottom surface of the inclined gravel chute 3, so that during the subsequent driving of the dump truck 1, the scraping plate 32 can scrape the gravel poured into the blind ditch through the inclined gravel chute 3 to ensure the flatness of the gravel layer. A bolt hole is provided at the top end of the scraping plate 32, and a plurality of threaded grooves are provided on the bottom side surface of the inclined gravel chute 3. The top end of the scraping plate 32 is fixed to one side of the inclined gravel chute 3 by a bolt, so that subsequent operators can remove the bolt and adjust the height of the movable clamping plate 23 to meet different construction requirements.

[0032] Among them, the permeable geotextile covering device 4 includes a support rod 41 fixed to the side surface of the inclined gravel chute 3 by a bolt, a cloth-releasing roller 42 rotatably installed on one side of the support rod 41, and a motor 43 fixed to the other side of the support rod 41 and having an output end connected to the cloth-releasing roller 42. During subsequent construction, the cloth-releasing roller 42 will be wound with the permeable geotextile to be laid. During the driving construction process of the dump truck 1, the motor 43 will operate, driving the cloth-releasing roller 42 to rotate, so as to continuously lay the permeable geotextile on the leveled gravel layer, improving the construction efficiency.
