[0025] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, in this embodiment, a waste asphalt mixture recycling benchmark metering device includes a base plate 1 and a mounting plate 2, characterized in that: the mounting plate 2 is at the top of the base plate 1, and a receiving assembly 5 is installed on the top of the mounting plate 2, the receiving assembly 5 includes a receiving frame 501 fixedly connected to the top outer wall of the mounting plate 2, and the inner cavity of the receiving frame 501 is inclined, and a blocking cover 502 is slidably inserted on the outside of the receiving frame 501, and the receiving frame 501 and the blocking cover 502 can form a complete closed space, a motor 503 is fixedly installed in the middle of both ends of the top outer wall of the mounting plate 2, and the two motor 503 shafts are coaxially fixed with a screw rod 504, and the two screw rods 504 are threadedly connected to the protruding part of the blocking cover 502, and a plurality of limit rods 505 are slidably inserted at both ends of the blocking cover 502, and the plurality of limit rods 505 are fixedly connected to the top outer wall of the mounting plate 2.

[0026] By starting two motors 503 to drive two screw rods 504 to rotate synchronously, the blocking cover 502 restricted by multiple limit rods 505 will be driven by the screw rod 504 to move upward. As the blocking cover 502 moves, a gap will be generated between it and the receiving frame 501, and the waste will slide outward from the gap along the slope of the receiving frame 501. The discharge speed can also be controlled by adjusting the size of the gap, which is beneficial to increase the adaptability of the device.

[0027] like Figure 1 As shown, weighing sensors 3 are fixedly installed on the four corners of the top outer wall of the base plate 1, and the mounting plate 2 is fixedly installed on the top of the four weighing sensors 3. The waste is introduced into the closed space formed by the receiving frame 501 and the blocking cover 502. The weight of the waste will be applied to the top of the weighing sensor 3 through the mounting plate 2, and the weighing sensor 3 can collect the weight information.

[0028] like Figure 2 and Figure 3 As shown, four corners of the bottom outer wall of the base plate 1 are fixedly connected to a support leg 4, and the four support legs 4 are installed with the same moving component 6.

[0029] The moving component 6 includes four mounting columns 604 that are slidably connected to the bottom outer walls of the four supporting legs 4, and a universal wheel 605 is fixedly installed on the bottom outer walls of the four mounting columns 604. The same bidirectional screw rod 601 is rotatably connected between the two supporting legs 4 at one end, and the two bidirectional screw rods 601 are symmetrically arranged. Both ends of the two bidirectional screw rods 601 are threadedly connected to a mounting block 602, and the bottoms of the four mounting blocks 602 are rotatably connected to a driving rod 603, and one end of the bottom of the four driving rods 603 is rotatably connected to the outside of the four mounting columns 604 respectively.

[0030] The outer walls of one side of the two supporting legs 4 are rotatably connected to a driven wheel 608, and a double-headed motor 606 is fixedly installed in the middle of the outer wall of one side of the base plate 1. A transmission wheel 607 is coaxially fixed at both ends of the double-headed motor 606.

At this time, only the universal wheel 605 of the device is in contact with the ground, which can ensure that the resistance encountered by the device when moving is small enough.

[0034] The utility model provides a reference metering device for recycling waste asphalt mixture, and the specific working principle is as follows:

[0035] When the device is working, the waste is introduced into the closed space formed by the receiving frame 501 and the blocking cover 502, and the weight of the waste is applied to the top of the weighing sensor 3 through the mounting plate 2, and the weighing sensor 3 can collect the weight information. After the operation is completed, the two motors 503 are started to drive the two screw rods 504 to rotate synchronously, and the blocking cover 502 restricted by the multiple limit rods 505 will be driven by the screw rods 504 to move upward. As the blocking cover 502 moves, a gap will be generated between it and the receiving frame 501, and the waste will slide outward from the gap along the slope of the receiving frame 501. The discharge speed can also be controlled according to the size of the gap, which is conducive to increasing the adaptability of the device. If the position of the metering device needs to be moved, the two transmission wheels 607 are driven by starting the double-headed motor 606. The two transmission wheels 607 can drive the two driven wheels 608 to rotate by meshing. The driven wheels 608 will drive the two bidirectional screw rods 601 to rotate synchronously. The bidirectional screw rods 601 will drive the two restricted mounting blocks 602 to move away from each other. The two mounting blocks 602 will respectively drive the two mounting columns 604 to slide down along the support leg 4 through the driving rod 603 until the overall length of the driving rod 603, the mounting column 604 and the universal wheel 605 is greater than the length of the support leg 4. At this time, only the universal wheel 605 of the device is in contact with the ground, which can ensure that the resistance encountered by the device when moving is small enough.
