The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model. Embodiment 1

[0030] A powder loading device, as Figure 1 shown, includes a hopper 4. To solve the problem of powder metering during loading, a number of second brackets 3 are evenly installed on the outer wall of the hopper 4, and the number of second brackets 3 is fixed to the platform 2 by bolts. A first bracket 1 is installed on the lower side of the platform 2 by bolts; a narrow and long window frame is opened on the outer wall of the hopper 4, and an observation window 5 is installed in the window frame. The observation window 5 is made of a transparent material, and the observation window 5 is marked with scales, and a nano - coating that can effectively prevent powder adhesion is applied to the surface of the observation window 5; a discharge port 11 is installed below the hopper 4, and a butterfly valve 19 is installed in the pipe of the discharge port 11.

[0031] By providing an observation window, before powder loading, the content of the powder in the hopper can be confirmed through the scales on the observation window, so as to achieve metered loading of the powder; at the same time, the transparent observation window facilitates the operator to observe the state of each component in the hopper and confirm whether the equipment needs maintenance.

[0032] This device is further provided such that a cover 10 is installed above the hopper 4, and a feed port 9 and an air extraction port 6 are opened on the cover 10.

[0033] By providing a cover, it is convenient for the operator to clean and maintain the inside of the hopper.

[0034] This device is further provided such that, as Figure 1-2 shown, a stirring mechanism is installed in the hopper 4. The stirring mechanism includes a motor 7. A number of motor brackets 8 are fixed to the surface of the cover 10 by bolts, and the motor 7 is fixed to the number of motor brackets 8; a stirring shaft bracket 17 is installed on the inner wall of the hopper 4. The stirring shaft bracket 17 and the cover 10 are rotatably installed with a stirring shaft 16 inside the hopper 4. A stirring blade 18 is installed at the lower end of the stirring shaft 16, and the upper end of the stirring shaft 16 is connected to the output shaft of the motor 7.

[0035] By providing a stirring mechanism, the stirring blade stirs the powder driven by the motor through the stirring shaft, increasing the fluidity of the powder and avoiding the accumulation of powder at the narrow part of the hopper during powder loading, which affects the loading efficiency.

[0036] The device is further configured such that a dust-proof cover is installed at the nozzle of the air extraction port 6.

[0037] Through the above solution, the dust-proof cover effectively prevents the dust in the hopper from being extracted from the hopper when the air extractor is working, thereby avoiding environmental pollution caused by dust and also preventing harm to the health of the staff.

[0038] To solve the problem of inconvenient movement of the device; as Figure 1-3 shown, a number of steering mechanisms 12 are installed below the first support 1. The steering mechanism 12 includes a steering bracket 22, which is fixed to the bottom of the first support 1. A steering shaft 21 is installed at the bottom end of the steering bracket 22, and a steering base 20 is installed at the bottom end of the steering shaft 21. A number of small wheels 23 are rotatably installed on both sides of the steering base 20 through shafts.

[0039] By setting the steering mechanism, under the operation of the small wheels and the steering shaft, the operator can very conveniently move the device to different positions for work.

[0040] The device is further configured such that a number of support legs 13 are fixed to the side surface of the bottom end of the first support 1. The number of support legs 13 is a hydraulically driven telescopic structure, and an anti-slip base 14 is installed at the top of the support legs.

[0041] By setting the support legs, when the device is working, the support legs will play a role in fixing the device, avoiding the device from moving and causing the powder to fail to be successfully loaded into the vehicle.

[0042] The device is further configured such that a thermometer 15 is installed inside the hopper 4 and below the end cover 10.

[0043] By setting the thermometer, the operator can observe the temperature change inside the hopper in real time.

[0044] Working principle: The operator drives the powder tanker to below the platform 2, then aligns the discharge port 11 of the device with the inlet port of the powder tanker and connects them through a hose. At the same time, by controlling the support legs 13 to extend, the anti-slip base 14 is pressed against the ground to fix the entire device; then the inlet port 9 is connected to the storage bin of the powder through a long pipe, and the air extraction port 6 is connected to the air extractor through a long pipe. The butterfly valve 19 is closed, and the air extractor is turned on. Under the operation of the air extractor, a negative pressure is formed inside the hopper 4, and the fluidized powder is sucked from the storage bin into the hopper 4. The operator confirms the amount of powder in the hopper through the observation window 5; after the pumping is completed, the air extractor is turned off, the butterfly valve 19 and the stirring mechanism are opened, and under the action of gravity, the powder falls from the hopper 4 into the powder tanker to complete the powder loading. Embodiment 2

[0045] In order to effectively stir and disperse the powdered materials piled up into blocks, as Figure 4 shown, the following improvements are made in this embodiment compared with Embodiment 1: A stirring mechanism is installed in the hopper 4. The stirring mechanism includes a motor 7. A plurality of motor brackets 8 are fixed on the surface of the end cover 10 by bolts. The motor 7 is fixed on the plurality of motor brackets 8. A stirring shaft bracket 17 is installed on the inner wall of the hopper 4. The stirring shaft bracket 17 and the end cover 10 are rotatably installed with a stirring shaft 16 inside the hopper 4. A support 24 is installed at the lower end of the stirring shaft 16. A plurality of groups of slender stirring rods 25 are installed on the circumferential outer wall of the support 24. The stirring rods 25 of each group are distributed in a spiral manner. The upper end of the stirring shaft 16 is connected to the output shaft of the motor 7.

[0046] Through the above solution, the slender stirring rods reduce the contact area with the powdered materials piled up into blocks, thereby providing a greater shearing force and more effectively dispersing the piled-up powdered materials. At the same time, the smaller contact area also reduces the load on the motor.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
