[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0017] As attached Figure 1-3 The screening and grinding device for putty powder shown in the figure includes a cylinder 1, a support frame 2 is provided in the middle of the outer surface of the cylinder 1, a discharge tray 3 arranged in a funnel shape is provided on the lower surface of the cylinder 1, and vibration motors 4 are installed on both sides of the lower surface of the discharge tray 3. Vibration guide holes 5 are provided at the four corners of the upper surface of the discharge tray 3 corresponding to the vibration motor 4, and a vibration guide rod 6 is welded and installed on the inner surface of the vibration guide hole 5. A sieve plate 7 is commonly installed on the upper surface of the vibration guide rod 6, and an opening is provided in the middle of the upper surface of the sieve plate 7. A sieve mesh 8 is installed on the inner surface of the sieve plate 7 through the opening.

[0018] A pressing plate 10 is provided above the sieve plate 7, a folding net 9 is installed between the upper surface of the sieve plate 7 and the lower surface of the pressing plate 10, a convex grinding plate 11 is provided in the middle of the lower surface of the pressing plate 10, a sealing cover 12 is installed on the upper surface of the cylinder 1, an electric push rod 13 is installed through the middle of the upper surface of the sealing cover 12, the output end of the electric push rod 13 is connected to the middle of the upper surface of the pressing plate 10, and a quick release is provided at the position where the pressing plate 10 is connected to the electric push rod 13. A quick connector, a sealing cover 12 and a feed port are provided on one side of the middle part of the upper surface of the pressing plate 10. A corrugated hose 14 is installed between the lower surface of the sealing cover 12 and the upper surface of the pressing plate 10. The two ends of the corrugated hose 14 are respectively connected to the sealing cover 12 and the feed port on the pressing plate 10. A discharge port is provided in the middle part of the lower surface of the discharge plate 3. The discharge plate 3 and the sealing cover 12 are respectively installed with a sealing nut 15 spirally inserted through the inner surface of the discharge port and the feed port.

[0019] During operation, the sealing nut 15 on the sealing cover 12 can be opened first to expose the feed port. At this time, the putty powder to be screened and ground can be poured into the feed port and flow into the sieve plate 7 through the corrugated hose 14. At this time, the vibration motor 4 can be started to generate vibration waves and transmitted to the sieve plate 7 through the vibration guide rod 6. At this time, the sieve plate 7 can cooperate with the screen 8 to vibrate and screen the putty powder. During the vibration screening process, the putty powder passing through the screen 8 will flow into the discharge plate 3. At this time, the sealing nut 15 inserted on the discharge plate 3 can be pulled out to expose the discharge port, thereby facilitating the discharge of the screened putty powder.

[0020] When the powder is screened, if the putty powder is difficult to pass through the sieve 8, the electric push rod 13 can be started to control the pressing plate 10 to extend toward the upper surface of the sieve plate 7. When the pressing plate 10 extends toward the upper surface of the sieve plate 7, the grinding plate 11 will be synchronously driven to contact the upper surface of the sieve plate 7. At this time, the grinding plate 11 can squeeze the putty powder on the sieve plate 7 under the continuous push of the electric push rod 13. At this time, the putty powder can be crushed under pressure. In this case, the continuous extension and contraction movement of the electric push rod 13 can continuously squeeze the putty powder on the sieve plate 7. The vibration screening of the sieve plate 7 is beneficial to avoid the problem that the putty powder is difficult to screen, thereby improving the efficiency of the putty powder screening and grinding. At the same time, the entire screening and grinding process is carried out in the cylinder 1, which is beneficial to avoid the dust spreading problem that is prone to occur in the traditional screening and grinding process, and is beneficial to reducing the impact on the construction environment.

[0021] In summary: the screening and grinding device is beneficial to improving the efficiency of putty powder screening and grinding, and is also beneficial to avoiding the dust spreading problem that is prone to occur in the traditional screening and grinding process.
