The end of the L-shaped plate 117 extends to the inner side of the U-shaped frame 110. The rear side of the inner cavity wall of the T-slot 116 is fixedly connected with a reset spring 118. The reset spring 118 is used to drive the L-shaped plate 117 to reset. The front end of 118 is fixedly connected to the outer side wall of the L-shaped plate 117, and the front side wall of the L-shaped plate 117 and the upper side of the T-slot 116 are fixedly connected with a knocking block 119, which is used to knock the feeding tube 115 to facilitate unloading, and the front side wall of the knocking block 119 is in contact with the rear side wall of the feeding tube 115. The top of the L-shaped plate 117 and the inner side of the U-shaped frame 110 are fixedly connected with an active ball 120, and the active ball 120 is used to cooperate with the extrusion strip 121 to drive the L-shaped plate 117 to move. The top of the inner side wall of the U-shaped frame 110 and the left and right sides of the front side of the slide groove 111 are fixedly connected with extrusion strips 121, and the extrusion strips 121 are used to move the active ball 120, and the extrusion strips 121 on both sides are evenly distributed from the inside to the outside. A mounting plate 130 is fixedly connected to the lower side of the middle of the left side wall of the mixing box 100. The mounting plate 130 is used to install a stirring motor 131. The top of the mounting plate 130 is fixedly connected to the stirring motor 131 by bolts. The stirring motor 131 is used to drive the stirring rod 132 to rotate. The output shaft of the stirring motor 131 is fixedly connected to the stirring rod 132. The stirring rod 132 is used to drive the stirring blade 133 to stir and drive the reciprocating screw rod 113 and the connecting rod 145 to rotate. The right end of the stirring rod 132 penetrates the mixing box 100 and extends to the outside of the mixing box 100. The outer wall of the stirring rod 132 and the inner cavity of the mixing box 100 are fixedly connected with a stirring blade 133. The stirring blade 133 is used to mix the powder and the liquid.The left end of the reciprocating screw 113 is connected to the outer wall of the stirring rod 132 and is located on the left side of the stirring box 100 through a belt drive.

The left side of the L-shaped plate 117 The movable ball 120 is driven to move while reciprocating rightward. When the movable ball 120 moves and contacts the extrusion bar 121, the extrusion bar 121 squeezes the movable ball 120 to make the movable ball 120 move backward. The L-shaped plate 117 moves backward through the movable ball 120 in cooperation with the T-slot 116. The L-shaped plate 117 drives the knocking block 119 to move backward while squeezing the return spring 118 to shrink it. When the movable ball 120 loses connection with the extrusion bar 121, the return spring 118 rebounds and drives the knocking block 119 through the L-shaped plate 117 to knock the feeding pipe 115 to generate vibration. The feeding pipe 115 thus cooperates with the filter screen to evenly scatter the powder.

[0031] In summary, the powder can be evenly sprinkled into the mixing box 100, thereby avoiding the situation where there is too much powder in some parts, which causes too much resistance and leads to suffocation of the tank.

At the same time, the strip brush plate 160 brushes the screening mesh plate 141 to prevent the screening mesh plate 141 from being blocked.

[0033] In summary, the agglomerated powder can be pretreated, thereby improving the mixing effect.

[0034] During specific use, personnel in this technical field add powder into the powder box 140, and then add liquid into the mixing box 100, and start the mixing motor 131 through the external controller. The output shaft of the mixing motor 131 rotates and drives the mixing blade 133 to rotate through the mixing rod 132 to mix.

In the tube 115, the reciprocating screw rod 113 drives the movable plate 114 to move back and forth through the slider 112, and the movable plate 114 drives the feeding tube 115 and the L-shaped plate 117 to move back and forth at the same time. The L-shaped plate 117 reciprocates left and right and drives the movable ball 120 to move. When the movable ball 120 moves and contacts with the extrusion bar 121, the extrusion bar 121 squeezes the movable ball 120 to make the movable ball 120 move backward. The L-shaped plate 117 moves backward through the movable ball 120 in cooperation with the T-slot 116. The L-shaped plate 117 drives the knocking block 119 to move backward and squeezes the reset spring 118 to shrink it.
