Specific embodiments
[0020] The solution of the present utility model will be further described below with reference to the accompanying drawings.
[0021] As Figure 1 shown, the present utility model is a road surface hot recycling integrated vehicle, and its structure mainly includes a vehicle body 1, a carriage 2, a stone bin 3, a road surface heating device 4, a stone spreading device 5, a material collecting device 6, a paving device 7, etc. Among them, the road surface heating device 4 is located below the vehicle body 1 and in front of the stone spreading device 5, the stone bin 3 is located in the middle of the carriage 2, the stone spreading device 5 is located below the vehicle body 1 and below the stone bin 3, the material collecting device 6 is located below the rear end of the vehicle body 1, and the paving device 7 is located behind the vehicle body 1. Through the above arrangement, when the vehicle body 1 of the present utility model moves forward, the road surface is sequentially heated, stones are spread, milling and material collection, and mixing and paving are carried out, so as to complete all the processes required for road surface hot recycling repair at one time.
[0022] Among them, the stone spreading device 5 is specifically located in front of the rear wheels of the vehicle body 1. The temperature of the heated road surface is relatively high. Laying a layer of stones first can effectively reduce the damage of the high-temperature road surface to the automobile tires.
[0023] As Figure 2 、 Figure 3 shown, the stone spreading device 5 includes a feeding chute 5-1, a roller shaft 5-2, a material guiding chute 5-4 and a conduit 5-5. The upper end of the feeding chute 5-1 is communicated with the bottom of the stone bin 3. The roller shaft 5-2 is located at the lower port of the feeding chute 5-1. The crushed stones in the stone bin 3 will enter the feeding chute 5-1 by gravity. The length of the feeding chute 5-1 is the same as the width of the stone bin 3.
[0024] The roller 5-2 is located at the lower end of the material discharging long groove 5-1. The axial direction of the roller 5-2 is consistent with the length direction of the material discharging long groove 5-1. The roller 5-2 is driven to rotate by the driving device 5-6. A discharge port 5-1-1 is arranged on one side of the lower end of the material discharging long groove 5-1. The lower end of the material discharging long groove 5-1 is in contact with the surface of the roller 5-2 or with a small gap. The stones in the lower part of the material discharging long groove 5-1 are in contact with the surface of the roller 5-2. The driving device 5-6 drives the roller 5-2 to rotate, and the friction between the surface of the roller 5-2 and the stones drives the stones to be discharged from the discharge port 5-1-1 on one side of the moving direction. The discharge speed of the stones can be adjusted by the rotation speed of the roller 5-2.
[0025] The driving device 5-6 is specifically a motor, and sprockets are respectively arranged on the motor shaft and the roller shaft 5-2, and the two sprockets are connected by a chain.
[0026] Among them, the discharge ports 5-1-1 are evenly distributed along the length direction of the long material feeding slot 5-1, the switch plate 5-3 contacts the side wall of the long material feeding slot 5-1, the switch plate 5-3 and the side wall of the long material feeding slot 5-1 are slidably connected, a plurality of tooth grooves 5-3-2 are arranged at the lower end of the switch plate 5-3, a baffle plate 5-3-1 is arranged between two adjacent tooth grooves 5-3-2, and the spacing between two adjacent tooth grooves 5-3-2 is consistent with the spacing between two adjacent discharge ports 5-1-1. When the switch plate 5-3 moves along the side wall of the long material feeding slot 5-1, the baffle plate 5-3-1 and the discharge port 5-1-1 overlap or stagger each other, thereby realizing the opening and closing of the discharge port 5-1-1.
[0027] In order to realize the movement of the switch plate 5-3, a transverse sliding hole 5-3-3 is opened on the switch plate 5-3, and a limiting bolt 5-3-4 is passed through the sliding hole 5-3-3. The limiting bolt 5-3-4 is connected to the side wall of the blanking slot 5-1, so that the switch plate 5-3 can only move horizontally a certain distance along the transverse sliding hole 5-3-3.
[0028] Furthermore, a gasket is provided on the limiting bolt 5-3-4, which can prevent the limiting bolt 5-3-4 from being separated from the sliding hole 5-3-3 and can reduce the friction between the limiting bolt 5-3-4 and the switch plate 5-3.
[0029] The adjustment of the gravel paving width is achieved through the material guide trough 5-4 and the guide tube 5-5.
[0030] Among them, a number of material guiding grooves 5-4 are respectively arranged at both ends of the roller shaft 5-2. The material guiding grooves 5-4 are located on the same side of the discharge port 5-1-1. A conduit 5-5 is rotatably connected to the lower end of each material guiding groove 5-4. The conduit 5-5 is of a bent structure. By rotating, the position of the lower port of the conduit 5-5 can be adjusted. The farther the distance that the lower port of the conduit 5-5 extends outwards, the larger the paving width of the stones.
[0031] Among them, a number of material guiding grooves 5-4 at one end of the roller shaft 5-2 correspond one by one to a number of discharge ports 5-1-1 at the end of the blanking long groove 5-1. After the stones are discharged from the discharge port 5-1-1, they enter the material guiding groove 5-4 and are discharged through the lower end of the material guiding groove 5-4.
[0032] In this specific embodiment, a conduit 5-5 is arranged at the lower end of every other material guiding groove 5-4. At the parts where the material guiding grooves 5-4 are arranged at both ends of the blanking long groove 5-1, after the stones are discharged from the discharge port 5-1-1 and enter the corresponding material guiding grooves 5-4, the stones in half of the material guiding grooves 5-4 directly fall to the ground naturally, and the stones in the other half of the material guiding grooves 5-4 enter the conduits 5-5 and are guided by the conduits 5-5 to fall to the ground at corresponding positions.
[0033] Among them, the conduit 5-5 has a certain length. By rotating, the lower port of the innermost conduit 5-5 can also be located outside the outermost material guiding groove 5-4. In this way, part of the stones can be guided to positions outside the end of the material guiding groove 5-4, and the paving width of the stones can be controlled by the rotation angle of the conduit 5-5.
[0034] A connecting pipe 5-7 is arranged at the lower end of the material guiding groove 5-4. A rotating sleeve 5-8 is arranged at the end of the connecting pipe 5-7. The end of the conduit 5-5 is connected to the rotating sleeve 5-8. Through the rotating sleeve 5-8, the rotation of the conduit 5-5 and the sealing between the conduit 5-5 and the connecting pipe 5-7 can be realized.
[0035] Such as Figure 4As shown, the utility model also includes a switch adjustment mechanism, through which the position of the switch plate 5-3 is adjusted. The switch adjustment mechanism includes an adjustment control plate 5-9, an operating shaft hole 5-10 and an operating rod 5-12. The adjustment control plate 5-9 is located at the end of the switch plate 5-3, and a plug hole 5-11 is provided on the adjustment control plate 5-9. The operating shaft hole 5-10 is located at the end of the feeding slot 5-1. A shaft rod 5-13 and a plug rod 5-14 are provided at the end of the operating rod 5-12. The shaft rod 5-13 and the plug rod 5-14 are parallel to each other. The shaft rod 5-13 is used to be plugged into the operating shaft hole 5-10, and the plug rod 5-14 is used to be plugged into the plug hole 5-11. When the switch plate 5-3 is moved, the plug rod 5-14 is inserted into the plug hole 5-11, the shaft rod 5-13 is inserted into the operating shaft hole 5-10, and the operating rod 5-12 is pulled to rotate the operating rod 5-12 around the shaft rod 5-13, thereby driving the switch to move horizontally through the plug rod 5-14.
[0036] Among them, the diameters of the plug hole 5-11 and the operating shaft hole 5-10 are relatively large, leaving room for the movement of the plug rod 5-14 and the shaft rod 5-13, so that the positions of the shaft rod 5-13 and the plug rod 5-14 are automatically adapted when the operating rod 5-12 and the switch plate 5-3 move.
[0037] The road surface heating device 4 includes a diesel tank, a combustion device, a heating plate and a circulating fan. Among them, the diesel tank is located in the car body 2, the heating plate is arranged under the car body 1 and in front of the gravel spreading device 5, the diesel tank is connected to the combustion device to supply diesel to the combustion device, the heating plate is a cover structure with an open lower end, the combustion of diesel in the combustion device generates high-temperature gas which is transported to the heating plate, and the circulating fan is located on the heating plate to drive the high-temperature gas to circulate in the heating plate. The utility model directly acts on the road surface through the heat generated by the combustion of diesel, has a high heating efficiency, can quickly heat and soften the road surface, and is particularly suitable for areas where there are restrictions on the transportation of bottled natural gas and the environment is relatively cold. A guide plate can be set in the heating plate, and the airflow in the heating plate is guided by the guide plate, and the circulating fan inside the heating plate is used to make the high-temperature gas circulate in a certain direction in the heating plate, thereby maximizing the use of the heat of the gas.
[0038] In addition, an asphalt tank 9 , a generator 8 and a flue gas dust removal device 10 are arranged in the carriage 2 .
[0039] The collecting device 6 cuts off the softened road surface material mixed with the scattered stones by planing and milling, adds new material to the cut material through the asphalt tank 9, and finally the paving device 7 performs paving.
[0040] The paving device 7 can be directly connected to the rear of the vehicle body 1, or can be hinged to the rear of the vehicle body 1 through a frame. When working, the paving device 7 is lowered to the ground, and when the work is completed, the frame is folded upward to the rear of the carriage 2.
[0041] During operation, the road surface heating device 4 generates flue gas, which is transported through a pipeline to the flue gas dust removal device 10 in the carriage 2. The flue gas dust removal device 10 includes a cooling device and a bag filter. The emission of flue gas can be effectively reduced through cooling and bag dust removal.
