[0052] The powder bin 12 is mounted on the powder bin mounting rack 13 through the weighing sensor 15, and the weighing sensor 15 is used to detect the amount of powder input into the powder bin 12.

[0053] The powder bin mounting rack 13 is mounted on the subframe 8 through the leveling mechanism 14, and the leveling mechanism 14 is used to control the powder bin 11 to always keep stable. The output end of the powder feeding device 11 is communicated with the powder bin 12, and the discharge port of the powder bin 12 is communicated with the mixer 3 through a batching conveyor 16.

[0054] Further, reference is made to the drawings and specific embodimentsFigure 4 , Figure 4 The structural schematic diagram of the powder feeding device provided by the embodiment of the application, the powder feeding device 11 comprises a fixed screw conveyor 112 and a movable screw conveyor 111. The fixed screw conveyor 112 is fixed on the auxiliary frame 8, and the output end of the fixed screw conveyor 112 is connected with the powder bin 12.

Of course, the setting mode of the rotating driving mechanism 113 is not limited to the above, and mainly ensures that the fixed screw conveyor 112 and the movable screw conveyor 111 can realize the relative rotation effect in the vertical direction under the condition that the internal material conveying is smooth.

[0059] Further, referring to the drawings attached to the specification Figure 5 , Figure 5 The structural schematic diagram of the leveling mechanism provided by the embodiment of the application, the leveling mechanism 14 comprises a first square frame 141, a second square frame 142 and a third square frame 143 which are sequentially stacked; the first square frame 141 is arranged on the auxiliary frame 8, and the top surface of the third square frame 143 is used to support the powder bin mounting frame 13.

[0061] The first inclined lifter in the same side can drive the end corner of the second frame 142 to be inclined and lifted relative to the other first inclined lifter; the second inclined lifter in the same side can drive the end corner of the third frame 143 to be inclined and lifted relative to the other second inclined lifter.

[0062] Further, the first inclined lifter comprises a first lifting oil cylinder 144, a first U-shaped seat 145 and a first rotating shaft 146 which are arranged at two ends of the first side; the first lifting oil cylinder 144 is arranged at the first side and the driving end is connected to the second frame 142; the first rotating shaft 146 is overlapped in the first U-shaped seat 145, one side of the first lifting oil cylinder 144 is lifted to drive the same side of the first rotating shaft 146 to be separated from the first U-shaped seat 145, and the other side of the first rotating shaft 146 rotates in the first U-shaped seat 145.

It can be predicted that the use mode of the second inclined lifter is the same as that of the first inclined lifter, and the leveling range of the leveling mechanism 14 can be affected by modifying the specific positions of the two on the frame side and the lifting range of the oil cylinder.

[0065] The second side frame 142 and the third side frame 143 are two whole bodies, and when one corner is lifted, the other positions will inevitably be lifted and inclined, that is, the two planes where the second side frame 142 and the third side frame 143 are located are lifted to be inclined planes, and the leveling effect of the powder bin 12 can be realized by respectively controlling the lifting of several oil cylinders, thereby avoiding the problem that the powder bin 12 is inclined and blocked during the input of the powder, thereby affecting the weighing accuracy.
