DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses a device for paving road construction waste materials.

[0039] Reference Figures 1 to 4 A road construction waste material paving device includes a material transport vehicle body 1, a material pipe 2 whose feeding end is connected to the material transport vehicle body 1, and a leveling mechanism 3 installed on the material transport vehicle body 1. An inclined leakage net 4 is installed in the discharge end of the material pipe 2, and a two-way conveyor 5 installed on the material pipe 2 is arranged on the lower side of the leakage net 4. The two-way conveyor 5 opens upward toward the leakage net 4 to form a material receiving port 6, and opens a plurality of lower slag discharge ports 7 downward, and the plurality of lower slag discharge ports 7 are arranged at intervals along a direction perpendicular to the travel direction of the material transport vehicle body 1.

[0040] The leakage net 4 can be made of steel plate, and a plurality of leakage holes are provided along the thickness direction thereof, and the size of the leakage holes can be punched according to actual needs. The leakage net 4 can also be made of steel bars interwoven and welded, and the hollowing is the leakage hole.

[0041] During the movement of the material transport vehicle 1, the material is discharged downward from the material pipe 2, and after being filtered through the filter screen 4 to separate large pieces of waste material, small pieces of waste material fall onto the two-way conveyor 5. Guided by the two-way conveyor 5, the material is transported in two directions perpendicular to the direction of travel of the material transport vehicle 1. During the transportation process, each material is discharged downward from a plurality of lower slag discharge ports 7 and falls evenly on the ground. At the same time, the filter screen 4 filters and separates large pieces of waste material, preventing relatively large pieces of material from piling up, making it easier for the leveling mechanism 3 to quickly level it, so as to improve the problem in the prior art that the diameters of the waste material blocks vary greatly, affecting the leveling effect.

[0042] Figure 1 In the figure, the material transport vehicle 1 is shown as an abbreviated structure, which can be a transport vehicle, a tanker, etc. A transmission structure such as a conveyor belt is provided to transport the material (waste material) to the feed port of the material pipe 2.

[0043] On the basis of the above embodiment, in order to fix the material pipe 2 , a mounting plate is fixed on the material transport vehicle body 1 to achieve cantilever support for the material pipe 2 .

[0044] The leveling mechanism 3 includes a second hydraulic rod fixedly arranged in the lower surface of the mounting plate between the leveling mechanism 3 and the discharge port, and a fixing plate is fixedly connected to the lower end of the second hydraulic rod. A plurality of groups of leveling rods symmetrically arranged in front and back positions are fixedly arranged on the lower surface of the fixing plate, and a leveling roller is rotatably connected between two leveling rods facing each other in front and back.

[0045] A leveling mechanism is also provided at the rear side of the leveling mechanism 3. The leveling mechanism includes a first hydraulic rod fixedly provided in the lower surface of the mounting plate, a fixed block fixedly provided at the lower end of the first hydraulic rod, and a plurality of slide cylinders symmetrically provided in the lower surface of the fixed block. A leveling rod is slidably provided inside the slide cylinder, a spring is fixedly connected between the upper end of the leveling rod and the top wall of the slide cylinder, and a leveling roller is rotatably provided between the two leveling rods facing each other in the front and rear.

[0046] During the movement of the material transport vehicle 1, the materials dropped from the material pipe 2 to the ground are first leveled by the leveling mechanism 3, and then squeezed and adjusted again by the leveling mechanism to achieve the leveling operation.

[0047] On the basis of the above embodiment, the material pipe 2 includes a drop pipe 21 whose feeding end is connected to the material transport vehicle 1 and a distribution pipe 22 whose upper end is connected to the discharge end of the drop pipe 21. The drop pipe 21 is connected to the middle end of the distribution pipe 22, and the filter 4 and the bidirectional conveyor 5 are arranged on the distribution pipe 22. The discharge end of the drop pipe 21 is located at the upper end of the filter 4. The material dropped from the drop pipe 21 directly falls to the upper end of the filter 4, so as to be fully filtered by the inclined setting of the filter 4.

[0048] Specifically, the material delivery pipe 21 is configured in an L-shape as a whole, one end of which is connected to the material transport vehicle body 1 , and the other end of which is bent downward to be connected to the material delivery pipe 22 .

[0049] The middle of the upper end of the material distribution pipe 22 is connected to the lower end of the material drop pipe 21, and the lower end of the material distribution pipe 22 opens downward to form a material drop opening. The length direction of the material distribution pipe 22 extends horizontally along a direction perpendicular to the direction in which the material transport vehicle 1 travels.

[0050] In order to achieve stable support for the material dropping pipe 21 and the material distribution pipe 22 , the material dropping pipe 21 and the material distribution pipe 22 can be supported respectively by fixing a cantilever on the material transport vehicle body 1 .

[0051] On the basis of the above embodiment, a discharge port 23 is provided on the side wall of the material distribution pipe 22 toward the lower end of the filter screen 4, and the discharge port 23 is detachably connected with a cover plate 24. After long-term filtering and separation work, the relatively large pieces of material accumulated at the lower end of the filter screen 4 can be discharged by opening the cover plate 24 for classified use.

[0052] Specifically, a connecting shaft 231 is fixed on the hole wall of the discharge port 23, one end of the cover plate 24 is rotatably connected to the connecting shaft 231, and the other end is penetrated by a plurality of bolts 25 which are threadedly connected to the material pipe 2. The cover plate 24 is fixed by the bolts 25, and when the material on the sieve 4 needs to be discharged, it only needs to unscrew the bolts 25, which is easy to operate.

[0053] The discharge port 23 is a square hole, and the connecting shaft 231 can be fixed on any wall of the hole.

[0054] On the basis of the above-mentioned embodiment, the opening length of the discharge port 23 is greater than the length of the leakage net 4 , so that the leakage net 4 can be disassembled and assembled through the discharge port 23 .

[0055] A handle is also fixed on the cover plate 24 for operation.

[0056] As a parallel solution, the cover plate 24 can also be detachably connected by means of snap connection or the like.

[0057] Reference Figures 3 to 5 The net 4 is an arc-shaped structure as a whole, and its two ends are bent downward, and the material pipe 2 drops the material in the middle of the net 4, and the drop point is located at the upper end of the net 4. When the material dropped from the drop pipe 21 directly falls to the upper end of the net 4, the two ends of the net 4 are bent downward, so that the material can roll to the two ends of the net 4, thereby improving the filtering effect.

[0058] A plurality of spaced guide plates 41 are fixedly connected to the upper side of the screen 4, and the guide plates 41 are arranged downwardly from the middle end of the screen 4 to the two ends. When the material rolls toward the two ends of the screen 4, the guide plates 41 guide the material so that the material rolls fully toward the two ends of the length direction of the screen 4 to achieve full filtration.

[0059] As one of the parallel installation methods, a plurality of groups of support plates 42 are arranged on the lower side of the leakage net 4, which are respectively located at the upper and lower ends thereof, and a plurality of support plates 42 are arranged at intervals at the two ends of the leakage net 4, and a spring 43 is fixedly connected to the support plate 42. The spring 43 is vertically arranged, and its lower end is fixedly connected to the support plate 42, and its upper end is fixedly connected to the upper end or the lower end of the leakage net 4.

[0060] When the material falls on the filter screen 4 and rolls on the filter screen 4, the plurality of springs 43 can form a shock-absorbing effect to relatively extend the service life of the filter screen 4. The vibration formed by the springs 43 can also relatively accelerate the filtering effect of the material.

[0061] As a second parallel installation method, the leakage screen 4 can also be installed in a fixed manner, specifically, it can be fixedly connected to the pipe wall of the material distribution pipe 22.

[0062] Reference Figures 3 to 5 The bidirectional conveyor 5 includes a shell 51 fixedly connected to the inner wall of the material distribution pipe 22 of the material pipe 2, a bidirectional screw rod 52 rotatably connected to the shell 51, and a driving member 53 installed on the material pipe 2. Both ends of the bidirectional screw rod 52 are rotatably connected to the pipe wall of the material pipe 2, the output end of the driving member 53 is transmission-connected to one end of the bidirectional screw rod 52, and the material receiving port 6 and the lower slag discharge port 7 are opened in the shell 51.

[0063] The driving member 53 includes a motor mounted on the outer wall of the material distribution pipe 22 via a mounting plate and a reduction box transmission-connected to the output end of the motor.

[0064] The shell 51 includes a bottom shell 511 and two inclined plates 512. The bottom shell 511 is an arc plate and is open upward. Both ends of the bottom shell 511 are fixedly connected to the pipe wall of the distribution pipe 22, and the lower ends of the two inclined plates 512 are respectively fixedly connected to the two arms of the open end of the bottom shell 511 to form a material receiving port 6. The upper ends of the two inclined plates 512 are fixedly connected to the inner wall of the material pipe 2, and each lower slag discharge port 7 is simultaneously opened in the bottom shell 511 and the two inclined plates 512.

[0065] The bidirectional screw rod 52 is arranged in the bottom shell 511, and includes a rotating shaft 521 with both ends rotatably connected to the tube wall of the material tube 2 and two spiral blades 522 fixedly connected to the two ends of the rotating shaft 521 respectively. One end of the rotating shaft 521 is transmission-connected to the output end of the driving member 53, and the rotation directions of the two spiral blades 522 are opposite.

[0066] When the driving member 53 drives the rotating shaft 521 to rotate, the two spiral blades 522 are driven to rotate synchronously, so that the material moves at a uniform speed at both ends along the length direction of the rotating shaft 521, and is discharged from the lower slag discharge port 7 during the movement, completing the material distribution. In this process, the two inclined plates 512 can guide the falling material, so that the material enters the bottom shell 511, and is pushed by the bidirectional spiral rod 52 and discharged uniformly from each lower slag discharge port 7.

[0067] On the basis of the above embodiment, a herringbone plate is fixed directly above the bidirectional screw rod 52. The herringbone plate is in the shape of a "human", and both ends of the length direction are fixedly connected to the inner wall of the cloth pipe 22, and the lower ends of the herringbone plate are respectively arranged toward the two inclined plates 512 to guide the material falling toward the bidirectional screw rod 52 and guide it to the inclined plate 512, thereby relatively forming a protective effect on the bidirectional screw rod 52 to prevent the material from directly hitting the spiral blade 522.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
