[0026] Reference Figure 3The rear end of the vibration motor 4 is fixedly connected to the top of the left inner wall of the furnace hood 2. The bottom plate 3 and the furnace hood 2 here provide stable operation support for the vibration motor 4. The left and right driving ends of the vibration motor 4 are fixedly connected with connecting rods 5. The vibration motor 4 here will drive the connecting rods 5 to vibrate when it is in operation. The other ends of the two connecting rods 5 are rotatably connected to the filter plate 6. The two connecting rods 5 here drive the filter plate 6 to vibrate when vibrating, thereby vibrating and dispersing the agglomerated metal powder thereon.

[0027] Reference Figure 3 The bottom end of the bottom plate 3 is fixedly connected to a support frame 7, and the four corners of the support frame 7 are fixedly connected to support blocks 8. The support blocks 8 here further provide stable support for the dispersion structure. The outer wall of the support block 8 is fixedly connected to the top left side of the inner wall of the furnace cover 2. The two connecting rods 5 are each provided with a spring sheet 9 on one side thereof. The connecting rod 5 here will also drive the spring sheet 9 to perform continuous telescopic movement when vibrating, thereby making the vibration amplitude larger and making the dispersion effect better.

[0028] Reference Figure 2-Figure 4 One end of the spring sheet 9 is fixedly connected to the outer wall of the support frame 7, and the other end of the spring sheet 9 is fixedly connected to the outer wall of the filter plate 6. The left bottom end of the furnace hood 2 is fixedly connected with a push-pull assembly, and the push-pull assembly here is used to push the scattered metal powder into the right side of the furnace hood 2 for heating treatment. The push-pull assembly includes a bottom block 10, and the right side of the bottom block 10 is fixedly connected to the left bottom end of the furnace hood 2, and the inner wall of the bottom block 10 is fixedly connected with a hydraulic rod 11.

[0029] Reference Figure 4 The bottom block 10 here provides a stable support for the hydraulic rod 11. The driving end of the hydraulic rod 11 is fixedly connected with a special-shaped block 12. The left side of the special-shaped block 12 contacts the bottom end of the left side of the inner wall of the furnace hood 2. The bottom end of the special-shaped block 12 is fixedly connected with a push-pull plate 13. When the hydraulic rod 11 here is started, it will drive the push-pull plate 13 to move left and right. The bottom end of the push-pull plate 13 is slidably connected to the top end of the table board 1, and the outside of the push-pull plate 13 is slidably connected to the bottom end of the inner wall of the furnace hood 2.

[0030] Reference Figure 4 The front and rear ends of the inner wall of the special-shaped block 12 are fixedly connected with a cylinder 14, and the driving end of the cylinder 14 is fixedly connected with a brush 15. The cylinder 14 here will drive the brush 15 to move left and right when it is in operation, which can effectively scrape off the metal powder attached to the bottom of the push-pull plate 13 to prevent waste. The bottom end of the brush 15 is in contact with the top of the inner wall of the push-pull plate 13, and the right side of the brush 15 is fixedly connected with a scraper 16. The scraper 16 here is used to gather the heated metal powder together for subsequent collection.

[0031] Reference Figure 2 and Figure 4The bottom end of the scraper 16 contacts the top of the inner wall of the push-pull plate 13. A plurality of heating plates 17 are fixedly connected to the right inner wall of the furnace hood 2. The heating plates 17 here are used to heat the scattered metal powder. A storage component is fixedly connected to the right side of the table board 1. The storage component includes a storage box 18. The top left side of the storage box 18 is fixedly connected to the right side of the table board 1. The storage component here, namely the storage box 18, is used to collect the metal powder that has been heated.

[0032] Working principle: When using this device, the staff can first put the metal powder to be heated into the top left side of the furnace cover 2 on the top of the table top 1, and then start the vibration motor 4 on the bottom plate 3. At this time, the vibration motor 4 will drive the connecting rod 5 to vibrate, thereby driving the support block 8 at its bottom to vibrate together. The support frame 7 and support block 8 here mainly play the role of supporting this vibration device, and the role of the spring sheet 9 is to make the vibration more intense, so that the effect of vibrating and dispersing the agglomerates in the metal powder is better.

[0033] Then, the metal powder that is vibrated into powder will fall from the holes of the filter plate 6 into the top of the special-shaped block 12, and then slide into the push-pull plate 13. At this time, the hydraulic rod 11 inside the bottom block 10 can be controlled to push the push-pull plate 13 into the right part of the furnace cover 2, and the heating plate 17 will start to heat the metal powder.

[0034] After the metal powder is heated, the hydraulic rod 11 can be controlled to push the push-pull plate 13 to the right. After pushing to the maximum distance, the cylinder 14 can be controlled to push the brush 15 to push the heated metal powder into the storage box 18. The brush 15 and the scraper 16 here can ensure the cleanliness of the inside of the push-pull plate 13 to prevent waste caused by any residue inside.
