[0019] This utility model provides, for example Figures 1-3 The device shown is a screening device for fruit and vegetable powder, including a barrel 1, the bottom of which is connected to a discharge hopper 13 for discharging material; a feeding trough 15 is provided on the top of the barrel 1, and a cover plate 16 is fitted on the feeding trough 15. In actual use, the cover plate 16 is opened to feed material into the feeding trough 15, and the cover plate 16 is used to close the feeding trough 15 during screening.

[0020] A support ring 14 is fixedly connected to the outer wall of the barrel 1. The support ring 14 is located in the lower half of the barrel 1. A support column 17 is fixedly connected to the lower surface of the support ring 14. Multiple support columns 17 are provided. The multiple support columns 17 are evenly distributed around the axis of the support ring 14, and at least three support columns 17 are provided to ensure the stability of the support.

[0021] Multiple support columns 17 and support rings 14 form a support structure to support the barrel 1, ensuring the stability of screening, while also keeping the discharge hopper 13 at a certain distance from the ground, making it convenient to place collection containers, etc.

[0022] A sieve plate 2 is slidably mounted inside the barrel body 1. A limiting assembly is installed below the sieve plate 2, comprising a support block 11 and an elastic telescopic rod 12. The support block 11 is fixedly connected to the inner wall of the barrel body 1, the bottom end of the elastic telescopic rod 12 is fixedly connected to the support block 11, and the top end of the elastic telescopic rod 12 is fixedly connected to the sieve plate 2. In actual use, multiple sets of limiting assemblies can be set to improve the stability of use.

[0023] A limiting component is installed so that the sieve plate 2 can only slide up and down inside the barrel 1 and will not rotate.

[0024] To improve screening efficiency, a rotating column 3 is rotatably connected to the screen plate 2. The rotating column 3 is concentric with the screen plate 2. A crossbar 4 is fixedly connected to the top of the outer wall of the rotating column 3. A corrugated annular groove 5 is opened on the inner wall of the barrel 1. The end of the crossbar 4 away from the rotating column 3 extends into the interior of the corrugated annular groove 5.

[0025] When the rotating column 3 rotates, it will drive the crossbar 4 to rotate synchronously. The end of the crossbar 4 away from the rotating column 3 slides inside the corrugated ring groove 5. Since the corrugated ring groove 5 is corrugated, the screen plate 2 will have an up-and-down shaking effect. The powder passes through the screen plate 2 and falls into the discharge hopper 13, improving the screening efficiency.

[0026] A scraper 6 is fixedly connected to the rotating column 3, and the scraper 6 is attached to the upper surface of the screen plate 2. The scraper 6 and the rotating column 3 are designed to be detachable, which facilitates the replacement of the scraper 6.

[0027] When the rotating column 3 rotates, it will drive the scraper 6 to stick to the upper surface of the sieve plate 2 and push and scrape. During the pushing and scraping process, the fruit and vegetable powder will be stirred. In conjunction with the sieve plate 2, it will produce an up and down shaking effect, which will further improve the screening efficiency. At the same time, it can push and scrape the particles accumulated on the surface of the sieve plate 2 to avoid clogging.

[0028] A square groove 7 is provided on the upper surface of the rotating column 3, and a square column 8 is slidably arranged inside the square groove 7. The square column 8 can drive the rotating column 3 to rotate synchronously.

[0029] A motor 10 is fixedly connected to the upper surface of the barrel 1. A rotating shaft 9 is rotatably connected to the top of the barrel 1. The top end of the rotating shaft 9 is fixedly connected to the drive shaft of the motor 10, and the bottom end of the rotating shaft 9 is fixedly connected to the square column 8. The motor 10 drives the square column 8 to rotate through the rotating shaft 9, and the rotating column 3 rotates synchronously.

[0030] In actual use, the motor 10 drives the square column 8 to rotate through the rotating shaft 9, and the rotating column 3 rotates synchronously. When the rotating column 3 rotates, it will drive the crossbar 4 to rotate synchronously. The end of the crossbar 4 away from the rotating column 3 slides inside the wave ring groove 5, and the sieve plate 2 produces an up-and-down shaking effect, which facilitates rapid screening. At the same time, the scraper 6 stirs the fruit and vegetable powder and can push and scrape the particles accumulated on the surface of the sieve plate 2.

[0031] By setting up structures such as crossbar 4, corrugated groove 5 and scraper 6, the screen plate 2 will produce an up-and-down shaking effect during screening, which facilitates rapid screening. The scraper 6 is attached to the upper surface of the screen plate 2 to push and scrape, agitating the fruit and vegetable powder and avoiding clogging, thereby improving the efficiency of the screening device for fruit and vegetable powder.
