[0002] In electronic devices, gallium oxide single crystal particles are mainly used to make capacitors, crystal oscillators, filters, amplifiers, switches, etc. Due to its good thermal stability, insulation performance, radio frequency function and corrosion resistance, gallium oxide single crystal particles are ideal materials for electronic devices. In addition, it can also be used to make temperature sensors, pyroelectric sensors and optical sensors.

[0003] In order to improve the effect of using gallium oxide single crystal particles, the gallium oxide single crystal particles need to be screened. The screening device can effectively screen potassium oxide single crystal particles. Gallium oxide single crystal particles with more uniform particle size and higher quality can be obtained through screening, thereby improving the use effect of gallium oxide single crystal particles. However, in the screening process of existing gallium oxide single crystal particles, since the raw material feeding method is one-time feeding through a feeding hopper, the one-time feeding is more likely to cause accumulation of the screening plate. The accumulation of raw materials will make it difficult to screen raw materials of different sizes, affecting the screening effect. Utility Model Content

[0006] Furthermore, it also includes a contact rod, a limit plate, a lever, a positioning ring and a spring. The contact rod is fixedly connected to the feed port opened on the rotating disk, the limit plate is fixedly connected to the inside of the funnel, the limit plate is slidably connected to the lever, the limit plate is provided with a positioning ring, the spring is wound on the lever, one end of the spring is fixed to the bottom of the limit plate, and the other end of the spring is fixed to the top of the positioning ring.

[0010] Furthermore, exhaust holes are provided on the top cover.

[0011] The beneficial effects are as follows: By meshing the gear with the rotating disk, the gear drives the rotating disk, and the feeding port on the rotating disk intermittently coincides with the feeding port on the blanking plate, so that the gallium oxide single crystal particles can intermittently fall from the feeding port to the screening machine, achieving the effect of quantitative feeding; Through the contact rod, the lever and the spring, when the lever contacts the contact rod, the spring is compressed and the lever moves upward, causing the lever to reciprocate up and down, achieving the effect of preventing the blanking port from being blocked.

[0018] Embodiment 1

[0019] A quantitative feeding device for screening gallium oxide single crystal particles, as Figures 1-3As shown in the figure, it includes a screening machine 1, a funnel 2, a slide rail 3, a rotating disk 4, a feed inlet 5, a bracket 6, a servo motor 7, a gear 8, a blanking plate 9 and a protective cover 17. The top of the screening machine 1 is fixedly connected with a funnel 2. In the middle of the funnel 2, a slide rail 3 is fixedly connected. On the slide rail 3, a rotating disk 4 is rotatably connected. Two feed inlets 5 are provided on the rotating disk 4. Outside the funnel 2, a bracket 6 is fixedly connected. On the bracket 6, a servo motor 7 is fixedly connected by bolts. One end of the output shaft of the servo motor 7 is fixedly connected with a gear 8. The gear 8 meshes with the rotating disk 4. In the middle of the funnel 2, a blanking plate 9 is fixedly connected. The blanking plate 9 is located on the top of the rotating disk 4. Two feed inlets 5 are provided on the blanking plate 9. The top of the screening machine 1 is fixedly connected with a protective cover 17. The bracket 6, the servo motor 7 and the gear 8 are located inside the protective cover 17.

[0020] As Figure 2 and Figure 4 shown in the figure, it further includes a contact rod 10, a limit plate 11, a dial rod 12, a positioning ring 13 and a spring 14. Inside the feed inlet 5 provided on the rotating disk 4, a contact rod 10 is fixedly connected. Inside the funnel 2, a limit plate 11 is fixedly connected. On the limit plate 11, a dial rod 12 is slidably connected. There is a positioning ring 13 on the limit plate 11. The spring 14 is wound around the dial rod 12. One end of the spring 14 is fixed at the bottom of the limit plate 11, and the other end of the spring 14 is fixed at the top of the positioning ring 13.

[0021] As Figure 1 and Figure 2 shown in the figure, it further includes a top cover 15 and an anti-slip pad 16. A top cover 15 is placed on the top of the funnel 2. There is a handle on the top cover 15. An anti-slip pad 16 is fixedly connected to the handle of the top cover 15. An exhaust hole 18 is provided on the top cover 15.

[0022] When it is necessary to screen gallium oxide single crystal particles, open the top cover 15, pour the gallium oxide single crystal particles into the funnel 2, start the servo motor 7. The servo motor 7 drives the gear 8 to rotate. The gear 8 meshes with the rotating disk 4. When the gear 8 rotates, it drives the rotating disk 4 to rotate. The rotating disk 4 rotates through the slide rail 3. When the symmetric feed inlets 5 of the rotating disk 4 coincide with the symmetric feed inlets 5 of the blanking plate 9, the gallium oxide single crystal particles fall into the screening machine 1 for screening. Through the rotation of the rotating disk 4, the symmetric feed inlets 5 of the rotating disk 4 and the symmetric feed inlets 5 of the blanking plate 9 coincide intermittently, achieving quantitative blanking.

[0023] When the feeding port 5 of the rotating disk 4 does not coincide with the feeding port 5 of the blanking plate 9, the rotating disk 4 presses the lever 12, causing the lever 12 to move upward and the spring 14 to compress. When the feeding port 5 of the rotating disk 4 coincides with the feeding port 5 of the blanking plate 9, the spring 14 resets, causing the lever 12 to slide downward. The feeding port 5 on the rotating disk 4 is provided with a contact rod 10. When the lever 12 contacts the contact rod 10, the spring 14 compresses and the lever 12 moves upward. The rotation of the rotating disk 4 causes the lever 12 to reciprocate up and down, thereby preventing the feeding port 5 of the blanking plate 9 from being blocked.

[0024] The hopper 2 is provided with a top cover 15. The top cover 15 can prevent accidents. There is an anti-slip pad 16 on the handle of the top cover 15. The anti-slip pad 16 can allow the staff to better open the top cover 15. The protective cover 17 can prevent the gear 8 from pinching the staff's hand. The top cover 15 is provided with an exhaust hole 18. The exhaust hole 18 can prevent the pressure in the gallium oxide single crystal particle screening machine 1 from being too high.
