This powder that remains on the inner wall of the pipe is difficult to clean and is likely to remain in the device for a long time. Long-term retention will cause the powder to deteriorate and cross-contamination will occur when it comes into contact with the powder that falls later. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced without the other ways different from the description, therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0024] Embodiment one: as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model provides a powder blanking device for ball mill equipment, including blanking pipe main body 1, one end of blanking pipe main body 1 is fixedly connected with change direction pipe 3, one end of change direction pipe 3 is fixedly connected with discharge pipe 4, and the lower surface of blanking pipe main body 1 is fixedly installed with vibration assembly 2;

[0025] Vibration assembly 2 includes knocking block 24, rotating rod 25 and transmission block 26, transmission block 26 is fixedly installed on the outer wall of rotating rod 25, and knocking block 24 and transmission block 26 are perpendicular to each other, and one end of knocking block 24 is lapped on the outer wall of blanking pipe main body 1;

[0026] The outer wall of blanking pipe main body 1 is fixedly installed with hollow box 21, rotating rod 25 is rotatably installed in the inside of hollow box 21, one end of hollow box 21 is fixedly connected with sub-box 22, sub-box 22 is fixedly installed with servo motor in the inside, and the output shaft of servo motor is fixedly connected with rotating rod 25 through shaft coupling, stirring rod 6 is rotatably installed in the inside of discharge pipe 4, and inclined plate 5 is fixedly installed at the joint of discharge pipe 4 and change direction pipe 3.

[0027] The specific settings and effects of the embodiment are as follows. One end of the main body of the discharging pipeline 1 is communicated with the discharge port of the bin, the discharge port of the discharging pipeline 4 is communicated with the ball mill, the powder in the bin enters the main body of the discharging pipeline 1, falls into the discharging pipeline 4 through the change direction pipeline 3, and finally enters the ball mill. The change direction pipeline 3 is used to ensure that the pipeline structure can adapt to the layout of different devices. The inclined plate 5 at the joint of the discharging pipeline 4 and the change direction pipeline 3 is used to guide the falling direction of the powder, so as to ensure that the powder falls on the stirring rod 6. The stirring rod 6 is connected with an external motor, and continuous rotation can avoid the blockage of the discharging pipeline 4.

[0028] During the process that the powder continuously enters the inside of the main body of the discharging pipeline 1, the vibration assembly 2 also continuously operates. The hollow box body 21 is installed on the lower surface of the main body of the discharging pipeline 1. The plate body on the lower surface of the main body of the discharging pipeline 1 is the plate body mainly contacted by the powder. The falling powder is concentrated on the plate body. The auxiliary box 22 is installed on the side of the hollow box body 21, and a servo motor for driving the rotating rod 25 is arranged in the auxiliary box 22. When the servo motor drives the rotating rod 25 to rotate, a plurality of transmission blocks 26 are driven to rotate together. The transmission blocks 26 are symmetrically arranged at equal intervals on the rotating rod 25. Three or four knocking blocks 24 knock the main body of the discharging pipeline 1 every half rotation.

[0029] The knocking blocks 24 continuously knock the main body of the discharging pipeline 1 to vibrate, so as to knock off the powder accumulated on the inner wall of the main body of the discharging pipeline 1, thereby solving the problem that the powder is retained in the device for a long time and avoiding the subsequent cross contamination of the powder.

[0030] Embodiment two: as shown in Figure 3 and Figure 4 The inner wall of the hollow box body 21 is fixedly installed with a positioning plate 23. The knocking block 24 is slidably connected in the positioning plate 23. One end of the knocking block 24 is fixedly installed with a contact plate 27. The edge of the transmission block 26 is lapped on one side of the contact plate 27. One side of the contact plate 27 is fixedly connected with a tension spring 28. The other end of the tension spring 28 is fixedly connected with one side of the positioning plate 23.

[0031] The effect of the whole embodiment is that the positioning plate 23 is used to determine the position of the knocking block 24. The knocking block 24 is in contact with the transmission block 26 through the contact plate 27. When the transmission block 26 rotates to the small head and is in contact with the contact plate 27 each time, the knocking block 24 is pushed to impact the main body of the discharging pipeline 1. In this process, the tension spring 28 is compressed synchronously, so as to ensure that the knocking block 24 does not violently impact the main body of the discharging pipeline 1, thereby protecting the main body of the discharging pipeline 1.

[0032] The method for using and the working principle of the device are as follows: one end of the discharging pipeline body 1 is communicated with a discharge port of a ball mill, the powder treated by the ball mill enters the discharging pipeline body 1, falls into the discharging pipeline 4 through the change direction pipeline 3, and the inclined plate 5 at the joint of the discharging pipeline 4 and the change direction pipeline 3 is used for guiding the powder to fall on the stirring rod 6, and the stirring rod 6 is continuously driven by the external motor in the process of falling of the powder;

[0033] In the process that the powder continuously enters the inside of the discharging pipeline body 1, the servo motor in the auxiliary box 22 continuously drives the rotating rod 25, drives a plurality of transmission blocks 26 by the rotating rod 25, and each time the transmission block 26 rotates to the small head and contacts the contact plate 27, the knocking block 24 is pushed to knock the discharging pipeline body 1, and each time the rotating rod 25 rotates half a circle, three or four knocking blocks 24 knock the discharging pipeline body 1.

[0034] In the process that the knocking block 24 is pushed by the transmission block 26, the tension spring 28 is compressed synchronously, so that the knocking block 24 cannot violently collide with the discharging pipeline body 1, the discharging pipeline body 1 is protected, and the vibration of the knocking block 24 continuously knocking the discharging pipeline body 1 can knock the powder remaining on the inner wall of the discharging pipeline body 1.

[0035] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belong to the protection scope of the present application.
