[0024] See also Figure 1-2 The utility model provides a technical solution: a Chinese medicinal material screening device, including a screening box 1, an upper screen 2 and a lower screen 4, the four corners of the bottom of the screening box 1 are vertically fixed with pillars 13, four pillars 13 are provided, the heights of the four pillars 13 are the same, and a support plate 131 is fixed to the bottom end of the pillar 13, the pillar 13 is perpendicular to the surface of the support plate 131, and the pillar 13 is stably supported on the ground by the support plate 131, thereby achieving stable support for the screening box 1.
[0025] The upper screen 2 and the lower screen 4 are tiltedly placed above and below the inside of the screening box 1, the left side of the upper screen 2 is rotatably connected to the left inner wall of the screening box 1 through a hinge 21, and the right side of the lower screen 4 is rotatably connected to the right inner wall of the screening box 1 through a hinge 21, and the surfaces of the front and rear ends of the screening box 1 above the right side of the upper screen 2 and the left side of the lower screen 4 are rotatably installed with an electric push rod 3 through a first hinge 31, and the ends of the electric push rod 3 are rotatably connected to the upper screen 2 and the lower screen 4 through a second hinge 32. The inclination angle of the upper screen 2 and the lower screen 4 can be controlled by the electric push rod 3, so that the upper screen 2 and the lower screen 4 can be adapted to different densities of Chinese medicine for screening. After the screening is completed, the electric push rod 3 drives the upper screen 2 and the lower screen 4 to the maximum inclination angle, and it is also convenient to slide and discharge the accumulated and stuck Chinese medicine.
[0026] A feed port 11 is connected to the upper side of the screening box 1, and the feed port 11 is connected to the interior of the screening box 1. The Chinese medicine to be screened enters the screening box 1 from the feed port 11, and then passes through the upper screen 2 and the lower screen 4 to be screened. Side panels 22 are fixed above the sides of the upper screen 2 and the lower screen 4. The side panels 22 are located on the surfaces of the upper screen 2 and the lower screen 4 on the side of the hinge 21, which has a blocking effect on the Chinese medicine and can prevent the Chinese medicine from contacting the hinge 21.
[0027] A side opening 14 connected to the interior of the screening box 1 is provided on the lower left surface of the screening box 1. The bottom of the left side of the lower screen 4 penetrates to the outside of the screening box 1 through the side opening 14. Large pieces of Chinese medicine are discharged from the side opening 14. A discharge port 12 is connected to the middle position of the bottom of the screening box 1. The discharge port 12 is connected to the interior of the screening box 1, and small pieces of Chinese medicine after screening are discharged from the discharge port 12.
[0028] When in use, the Chinese medicine to be screened is put into the interior of the screening box 1 from the feed port 11, and the Chinese medicine slides downward, passes through the upper screen 2 and the lower screen 4 inside the screening box 1 in turn, and the screening causes small pieces of Chinese medicine to fall to the bottom and finally be discharged from the discharge port 12, while large pieces of Chinese medicine slide to the left from the lower screen 4 and finally be discharged from the side port 14 to the outside for collection. When screening Chinese medicines of different densities, the inclination angles of the upper screen 2 and the lower screen 4 can be adjusted by the electric push rod 3, and the screening density is large. When screening Chinese medicine with large density, the upper screen 2 and the lower screen 4 are tilted at a smaller angle to ensure thorough screening of the Chinese medicine. When screening Chinese medicine with low density, the upper screen 2 and the lower screen 4 are tilted at a larger angle to ensure that large pieces of Chinese medicine can slide down the surfaces of the upper screen 2 and the lower screen 4 and be discharged from the outside. After the screening work is completed, the electric push rod 3 can be controlled to drive the upper screen 2 and the lower screen 4 to tilt to the maximum angle, so that the Chinese medicine accumulated on the surfaces of the upper screen 2 and the lower screen 4 can slide downward and be discharged from the side port 14.
