[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figures 1-4 This utility model provides a technical solution: a graded mixing device for reclaimed water stabilizing layer materials, comprising a mixing component 100, a conveying component 200, a grading component 300, and a crushing component 400.
[0030] The mixing assembly 100 includes a barrel 110, a first motor 120 disposed at the top of the barrel 110, a mixing rod 130 connected to the output end of the first motor 120 and rotating inside the barrel 110, and a discharge port 140 disposed at the bottom of the barrel 110 for discharging materials.
[0031] The conveying assembly 200 includes a conveying box 210 disposed on the top of the barrel 110, a second motor 220 disposed on the outer edge of the conveying box 210, a spiral conveying rod 230 disposed at the output end of the second motor 220 and rotating inside the conveying box 210, and a connecting pipe 240 connecting the discharge end of the conveying box 210 and the upper end of the barrel 110.
[0032] The grading assembly 300 includes a grading box 310 that is fixedly installed on the top of the conveyor box 210 and interconnected with each other, a screening screen 320 that is fixedly installed inside the grading box 310 and tilted to the right at one end, and a feed inlet 330 that is installed on the top of the grading box 310 for raw material entry.
[0033] The crushing assembly 400 includes a crushing box 410 fixedly installed on the upper part of the outer wall of the barrel 110, a third motor 450 fixedly installed on one end of the outer wall of the crushing box 410, a shaft 422 fixedly connected to the output end of the third motor 450, a crushing roller 420 rotatably installed inside the crushing box 410 and connected to the two shafts 422, two gears 421 fixedly sleeved on the outer walls of the two shafts 422 and meshing with each other, a large stone discharge pipe 430 extending into the grading box 310 from one end of the top of the crushing box 410, and a discharge pipe 440 extending into the barrel 110 from the other end of the outer wall of the crushing box 410.
[0034] This equipment is set up so that the discharge part of the water-stabilized layer mixture conveyor is aligned with the inlet 330 set at the top of the grading box 310, and the material is conveyed into the grading box 310. The initial mixed raw materials are graded by the screening screen 320 inside the grading box 310, and large stones that are not easy to mix are separated. The large stone discharge pipe connected to the discharge end of the screening screen 320 enters the crushing box 410. The raw materials that meet the mixing requirements fall into the conveying box 210 below. The second motor 220 drives the screw conveyor 230 to push the material to the connecting pipe 240. The connecting pipe 240 is connected to the upper end of the barrel 110, and the material to be mixed is conveyed into the mixing component 100 for mixing.
[0035] The third motor 450 drives the connected shaft 422 to rotate, causing the two gears 421 on the shaft 422 to rotate in opposite directions. The third motor 450 rotates counterclockwise, causing the left crushing roller 420 to rotate clockwise and the right roller to rotate counterclockwise. This crushes large stone raw materials into qualified gravel. The crushed and easily mixed material is then transported back into the barrel 110 for mixing through a discharge pipe 440 located on the edge of the crushing box 410 and extending to the top of the barrel 110. This improves the mixing efficiency in the reclaimed water stabilization process and eliminates the need for manual collection and crushing of large stones, reducing labor costs.
[0036] See Figure 1 and Figure 2 In some embodiments, an L-shaped support rod 500 is fixedly connected to the outer wall of the barrel 110, and the upper end of the support rod 500 is fixedly connected to the bottom of the crushing box 410.
[0037] The support rod 500 provided on the barrel 110 is connected at one end to the bottom of the crushing box 410, which strengthens the installation of the crushing box 410.
[0038] See Figure 1 and Figure 2 In some embodiments, the stirring rod 130 does not contact the inner wall of the barrel 110 on both sides, and the bottom end of the stirring rod 130 is shortened according to the inclination angle of the discharge part of the barrel 110.
[0039] The stirring rods 130 on both sides do not contact the inner wall of the barrel 110. At the same time, the lower end of the stirring rods 130 extends to the discharge end of the barrel 110. They rotate at the bottom of the discharge end of the barrel 110 to achieve a stirring effect, which can prevent the discharge end of the barrel 110 from being blocked.
[0040] See Figure 2 In some embodiments, the size of the filter holes of the screen plate 320 is matched to the size required for mixing the materials, and the discharge end of the screen plate 320 is opposite to the feed end of the large stone drain pipe 430.
[0041] See Figure 2 and Figure 4 In some embodiments, the top of the crushing box 410 is provided with a connection port 411 that connects to the discharge end of the large stone drain pipe 430, and the connection port 411 is located in the middle of the two crushing rollers 420.
[0042] The connection port 411 is located in the middle of the two crushing rollers 420, so that the material conveyed from the large stone drain pipe 430 falls into the crushing part of the two crushing rollers 420, which can improve the crushing efficiency.
[0043] See Figure 4 In some embodiments, the pins on the two crushing rollers 420 are staggered, and the crushing distance between the two crushing rollers 420 is set within the range of the required fineness of the water-stabilized layer raw material.
[0044] The studs on the two crushing rollers 420 are staggered to crush the raw materials. The distance between the two crushing rollers 420 should be set to meet the fineness requirements of the crushed material to avoid the crushed material being too large and difficult to mix with other materials.
[0045] See Figure 2 and Figure 4 In some embodiments, the crushing box 410 has an installation cavity 412 for mounting two gears 421. The two shafts 422 are supported by bearings and rotate inside the crushing box 410. The installation cavity 412 in the crushing box 410 is used to separate the two gears 421 from the crushing part of the crushing box 410 and to protect the gears 421.
