Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a powder feed screening and mixing device, including a screening barrel 1. In the middle of the inner wall of the screening barrel 1, two fixed screens 3 are fixedly connected. Between the two adjacent fixed screens 3, an adjustable screen 4 is arranged. On the inner bottom wall of the upper fixed screen 3, a conical plate 5 is fixedly connected. On the inner walls of the two fixed screens 3 and the adjustable screen 4, a plurality of leakage holes 6 are equidistantly arranged. At the bottom of the bottom fixed screen 3, a vibration motor 7 is fixedly connected. The bottom of the vibration motor 7 is fixedly connected to the middle of the inner bottom wall of the screening barrel 1. The inner bottom wall of the screening barrel 1 has an inclination angle. In the middle of the front side of the screening barrel 1, an adjustment slot 8 is fixedly connected. At the top of the front side of the adjustment slot 8, a plurality of teeth 9 are equidistantly fixedly connected. On the front side of the adjustable screen 4, a support rod 10 is fixedly connected. At the front end of the support rod 10, a rotating shaft 11 is rotatably connected. At the front end of the rotating shaft 11, an extension rod 12 is rotatably connected. At the front end of the extension rod 12, a handle 13 is fixedly connected. The extension rod 12 is meshed and connected with the plurality of teeth 9 adjacent thereto. At the bottom right side of the screening barrel 1, a feeding pipe 14 is communicated. At the bottom of the feeding pipe 14, a stirring device 2 is arranged;

[0031] Specifically, two fixed screens 3 are arranged in the screening barrel 1. An adjustable screen 4 that can be rotated to adjust its position is arranged between these two screens. A plurality of leakage holes 6 are equidistantly arranged on the inner walls of these three screens. The sizes of these leakage holes 6 determine the size of the feed particles that can pass through. At the top of the front side of the adjustment slot 8, a plurality of teeth 9 are equidistantly fixedly connected. On the front side of the adjustable screen 4, a support rod 10 is connected. The front end of the support rod 10 is connected to the extension rod 12 through the rotating shaft 11. At the front end of the extension rod 12, a handle 13 is fixedly connected. The user can rotate the handle 13 to rotate the extension rod 12 upward. When the user rotates the handle 13, the extension rod 12 will move upward around the rotating shaft 11 and drive the support rod 10 to move back and forth by moving sideward. At the same time, the movement of the support rod 10 will drive the adjustable screen 4 to rotate between the fixed screens 3. Through such an operation, the user can adjust the position of the adjustable screen 4 as needed, and then change the distance between the leakage holes 6 in the adjustable screen 4 and the leakage holes 6 in the fixed screen 3, so as to adjust the overlapping size between the leakage holes 6 and the leakage holes 6. After the adjustment is completed, the user can engage the front end of the extension rod 12 between the teeth 9 to achieve fixation. After the fixation is completed, the vibration motor 7 in the screening barrel 1 starts to work, driving the entire screening device to vibrate, causing the powder feed to roll above the screen. The feed with smaller particles will fall through the leakage holes 6 to the lower part, while the feed with larger particles will be left above the screen. At the bottom right side of the screening barrel 1, a feeding pipe 14 is communicated. The screened feed will be discharged through the feeding pipe 14, making the whole device simple to operate and capable of efficiently and accurately completing the screening work of the powder feed.

[0032] Referring to Figure 1 andFigure 3 , the stirring device 2 includes a stirring barrel 201. A stirring motor 202 is fixedly connected to the top wall of the stirring barrel 201. A rotating shaft 203 is fixedly connected to the middle of the bottom end of the stirring motor 202. Stirring blades 204 are fixedly connected to both the left and right sides of the rotating shaft 203. A plurality of pressurizing slits 205 are formed in the inner walls of the two stirring blades 204. A fixing ring 206 is fixedly connected to the upper middle part of the inner wall of the stirring barrel 201. A stabilizing disc 207 is fixedly connected to the upper middle part of the outer wall of the rotating shaft 203. The stabilizing disc 207 is slidably connected to the fixing ring 206. An anti-slip base 208 is fixedly connected to the bottom end of the stirring barrel 201;

[0033] Specifically, after starting the stirring motor 202 on the stirring barrel 201, power is transmitted through the rotating shaft 203 to make the stirring blades 204 start to rotate. The stirring blades 204 are the key components for mixing feed. When the stirring motor 202 drives the rotating shaft 203 to rotate, the stirring blades 204 will also rotate accordingly. A plurality of pressurizing slits 205 are provided on the inner walls of the stirring blades 204. Since the shape of the pressurizing slits 205 is conical, it helps to generate local high-pressure and low-pressure regions during the rotation process, thereby promoting the mixing and dispersion of the feed. To increase the stability of stirring, a fixing ring 206 is provided in the upper middle part of the inner wall of the stirring barrel 201 and is slidably connected to the stabilizing disc 207 fixed to the outer wall of the rotating shaft 203. Such a design can ensure that the stirring blades 204 remain stable during high-speed rotation. At the same time, the anti-slip base 208 can ensure that the device can be stably placed on the ground or other planes during the stirring process, preventing position movement caused by vibration or external forces and improving the mixing efficiency.

[0034] Refer to Figure 1 , a fixing plate 15 is fixedly connected to the left bottom end of the stirring barrel 201. A suction pump 16 is fixedly installed in the middle of the top wall of the fixing plate 15. The right end of the suction pump 16 communicates with the left middle part of the stirring barrel 201. A discharge pipe 17 is connected to the top end of the suction pump 16; Two columns 18 are fixedly connected to the left bottom end of the fixing plate 15. Anti-slip pads 19 are fixedly connected to the bottom ends of the two columns 18; A feed pipe 20 communicates with the left top end of the screening barrel 1. An inclination angle is provided in the inner wall of the feed pipe 20;

[0035] Specifically, the fixing plate 15 serves as the basic structure for connecting and supporting the suction pump 16, which can ensure the stability of the suction pump 16 during operation. The suction pump 16 generates negative pressure to suck out the already stirred feed in the stirring barrel 201 and discharges it to the required place through the discharge pipe 17. The columns 18 are used to support the fixing plate 15 and prevent the fixing plate 15 from tilting. The anti-slip pads 19 increase the friction between the columns 18 and the ground, preventing the suction pump 16 from sliding or moving during operation and ensuring the safety of the operation. The feed pipe 20 is used to convey the feed to be screened into the screening barrel 1. An inclination angle is provided in the inner wall of the feed pipe 20, which helps the feed to flow smoothly and prevents blockage.

[0036] Refer to Figure 1 , in the middle and lower part of the front side of the mixing barrel 201, a control console 21 is fixedly connected. On the top wall of the control console 21, a plurality of control buttons 22 are fixedly installed. The plurality of control buttons 22 are electrically connected to the vibration motor 7, the material suction pump 16, and the mixing motor 202 respectively; on the front side of the top wall of the mixing barrel 201, a tachometer 23 is fixedly connected. The tachometer 23 is electrically connected to the control console 21; on the bottom wall of the screening barrel 1, a plurality of support columns 24 are fixedly connected. The bottom ends of the plurality of support columns 24 are all fixedly connected to the top wall of the mixing barrel 201;

[0037] Specifically, the vibration motor 7, the material suction pump 16, and the mixing motor 202 are controlled through the control buttons 22 on the control console 21, and different powers and durations can be achieved to ensure uniform mixing of the feed. The tachometer 23 is used to monitor the rotation speed of the mixing motor 202 in real time, ensure that the mixing motor 202 operates within the set rotation speed range, and is connected to the control console 21 to display the rotation speed information on the control console 21 in real time, facilitating the operator to monitor and adjust. The support columns 24 are used to support the screening barrel 1 to ensure the stability and safety of the screening barrel 1.

[0038] Working principle: There are two fixed screens 3 in the screening barrel 1. Between these two screens, an adjustable screen 4 that can be rotated to adjust its position is provided. A plurality of leakage holes 6 are equidistantly opened on the inner walls of these three screens. The sizes of these leakage holes 6 determine the size of the feed particles that can pass through. At the front top of the adjustment slot 8, a plurality of teeth 9 are fixedly arranged at equal intervals. A support rod 10 is connected to the front side of the adjustable screen 4. The front end of the support rod 10 is connected to an extension rod 12 through a rotating shaft 11, and a handle 13 is fixed at the front end of the extension rod 12. The user can rotate the handle 13 to rotate the extension rod 12 upward. When the user rotates the handle 13, the extension rod 12 will move upward around the rotating shaft 11, and drive the support rod 10 to move back and forth by moving sideways. At the same time, the movement of the support rod 10 will drive the adjustable screen 4 to rotate between the fixed screens 3. Through such an operation, the user can adjust the position of the adjustable screen 4 according to needs, and then change the distance between the leakage holes 6 in the adjustable screen 4 and the leakage holes 6 in the fixed screen 3, so as to adjust the overlapping size between the leakage holes 6 and the leakage holes 6. After the adjustment is completed, the user can engage the front end of the extension rod 12 between the teeth 9 to achieve fixation. After the fixation is completed, the vibration motor 7 in the screening barrel 1 starts to work, driving the entire screening device to vibrate, causing the powdery feed to roll above the screen. The feed with smaller particles will fall through the leakage holes 6 to the lower part, while the feed with larger particles will be left above the screen. The right bottom end of the screening barrel 1 is communicated with a discharge pipe 14, and the screened feed will be discharged through the discharge pipe 14, making the entire device simple to operate and capable of efficiently and accurately completing the screening work of the powdery feed.

[0039] After starting the stirring motor 202 on the stirring barrel 201, power is transmitted through the rotating shaft 203, causing the stirring blades 204 to start rotating. The stirring blades 204 are key components for the mixed feed. When the stirring motor 202 drives the rotating shaft 203 to rotate, the stirring blades 204 will also rotate accordingly. Multiple pressurizing slits 205 are provided on the inner wall of the stirring blades 204. Since the shape of the pressurizing slits 205 is conical, it helps to generate local high-pressure and low-pressure regions during rotation, thereby promoting the mixing and dispersion of the feed. To increase the stability of stirring, a fixed ring 206 is provided in the upper-middle part of the inner wall of the stirring barrel 201 and is slidably connected to a stabilizing disk 207 fixed to the outer wall of the rotating shaft 203. Such a design can ensure that the stirring blades 204 remain stable during high-speed rotation. At the same time, during the stirring process, the anti-slip base 208 can ensure that the device can be stably placed on the ground or other planes, preventing position movement caused by vibration or external forces, and improving the mixing efficiency.
