[0047] Working principle:

[0048] When in use, the material is first transported from the material machine to the tipping bucket 10 of the tipping weighing mechanism 3. At this time, the material is settled in the tipping bucket 10. After the material is weighed by the weighing component in the tipping weighing mechanism 3 and meets the standard, the swing cylinder 11 fixed on the tipping shell 9 starts to work, and the tipping bucket 10 is connected to the rotating shaft of the swing cylinder 11. Therefore, under the rotation of the swing cylinder 11, the tipping bucket 10 is driven to rotate along the rotating shaft to flip the material in the tipping bucket 10 and pour it into the buffer hopper 4 in the skid-mounted pumping assembly 1. At the same time, a window is opened on the weighing base 12 to facilitate the passage of materials. The weighing base 12 is fixed under the tipping shell 9 to support the tipping weighing mechanism 3. The weighing base 12 is connected to the box frame 17 by a pin and can be quickly disassembled and assembled.

[0049] When the material enters the cache hopper 4, it enters the outer shell 63 in the double screw conveyor 6 under the action of gravity. The outer shell 63 is fixed in the box frame 17 by screws. The power of the double screw conveyor 6 comes from the stepper motor 61. When the material enters the cache hopper 4, the stepper motor 61 starts to work, and the stepper motor 61 transmits the power to the inside of the transmission box 62, and with the cooperation of the gears inside the transmission box 62, it drives the double screw rod 64 in the outer shell 63 to rotate to extrude and convey the material. At this time, the material is pre-pressed into the hopper of the plunger conveying pump 8 through the double screw conveyor 6, and the hydraulic system 7 fixed on the box frame 17 provides stable power for the plunger conveying pump 8 to pump the material to the pump outlet. The pump outlet can be connected to the pipeline through a quick connector to achieve the purpose of conveying the material and measure the material conveying amount during the conveying process.

[0050] A cooling fan 19 is connected to the box frame 17. The temperature in the device can be cooled by turning on the cooling fan 19. In addition, when the flip weighing mechanism 3 needs to be repaired, the top of the box frame 17 can be walked along the step ladder 21 in the box frame 17. A maintenance platform 2 is provided on the platform at the top of the box frame 17. The guardrail 22 of the maintenance platform 2 can be connected to the box frame 17 by a pin, and can be connected to the protruding part of the box frame 17 by a support rod 23. The support rod 23 can also be connected to the hanging ear 15 of the box frame 17 and the guardrail 22 by a pin.
