[0004] Although the above-mentioned tundish dry material distributing equipment realizes the automation of distributing, during the operation, since the tundish dry material is mostly in powder form and the tundish dry material is introduced into the discharging trough through the guide plate, when the molecules (or atoms, ions) inside the tundish dry material powder collide with the powder surface, the powders will interact with each other, causing some molecules (atoms, ions) to remain on the powder surface, making the concentration of these molecules (or atoms, ions) on the powder surface greater than that in the powder, thereby increasing the adsorption force of the powder, causing the powder to be easily adsorbed on the guide plate, thereby affecting the distributing.

A feeding hopper 7 is fixedly installed on the middle part of the top surface of the discharging box 1, and a guide plate 8 is fixedly welded on the lower part of the inner cavity of the feeding hopper 7.

[0028] See also Figure 1-Figure 4 An active cavity 81 is provided inside the guide plate 8 , and a fixing rod 82 is fixedly welded inside the active cavity 81 .

[0029] See also Figure 1-Figure 4 A deflection plate 83 is movably sleeved on the outer surface of the fixed rod 82 to ensure that the deflection plate 83 can deflect along the circumferential direction of the fixed rod 82. A knocking block 84 is fixedly welded on the outer surface of the upper part of the deflection plate 83 to facilitate the deflection of the knocking block 84 during the deflection of the deflection plate 83, so that the knocking block 84 is used to knock on the side wall of the movable cavity 81, thereby causing the guide plate 8 to vibrate.

[0030] See also Figure 1-Figure 4 A spring 85 is fixedly welded to the middle of the right side of the deflection plate 83, and one end of the spring 85 away from the deflection plate 83 is fixedly welded to the side wall of the active cavity 81.

[0032] Working principle: When the tundish dry material needs to be distributed, the guide rail 2 is used to slide the discharge box 1 onto the mold body, and the tundish dry material powder is placed into the discharge box 1 through the feed hopper 7. Then the motor 5 is turned on, and the motor 5 drives the spiral feed rod 4 to rotate to transport the tundish dry material, so that the tundish dry material powder is discharged through the discharge pipe 6 and distributed. At this time, the spiral feed rod 4 is rotated so that the spiral blade on the spiral feed rod 4 will toggle the lever 86, and the lever 86 will drive the The movable deflection plate 83 deflects along the fixed rod 82, and at the same time prompts the spring 85 to store energy. When the spiral blade on the spiral feeding rod 4 leaves the shifting rod 86, the deflection plate 83 will continue to deflect due to the potential energy of the spring 85, thereby driving the knocking block 84 to continuously knock the side wall of the active cavity 81, prompting the guide plate 8 to vibrate. At this time, the vibration of the guide plate 8 causes the intermediate bag dry material powder adsorbed on the guide plate 8 to fall off, effectively preventing the intermediate bag dry material powder from being adsorbed on the guide plate 8 and affecting the distribution of the material.
