[0015] The beneficial effects of this invention are as follows:

[0016] 1. A material feeding cylinder is rotatably mounted on an inclined support. The material feeding cylinder can blow air through the filter cover on the bottom sealing plate and the blower fan on the top cover plate to blow air onto the Chinese herbal raw materials inside. At the same time, the vibration motor on the surface can shake the Chinese herbal raw materials into small particles and collect them into the bottom cover with the help of the filter cover. The filter cover can also effectively reduce the backflow of material in the bottom cover into the material feeding cylinder.

[0017] 2. By setting two sets of second connecting rods at the bottom of the base cover, the base cover is secured to the sealing plate by a T-shaped limiting rod and a limiting spring. The second connecting rods slide into the insert sleeve via a slider, while the insert sleeve rotates onto the surface of the crossbar. The crossbar is pulled downwards by the first connecting rods on the left and right sides and the electric telescopic rod, thus pulling down the base cover. When the crossbar is pulled down, the front end of the waste hopper is pulled upwards and rotated by the limiting rope, facilitating the cleaning and collection of waste inside the base cover. The upward tilting of the waste hopper effectively reduces dust when waste falls. At the same time, a guide block is set inside the waste hopper to guide the falling waste to both sides, which, together with the discharge channels at the bottom of both sides, discharges the waste into the collection hopper. Two auxiliary discharge hoses are set on the surface of the material cylinder, with their bottoms extending downwards to the connection between the waste hopper and the discharge channel. The vibration driven by the small vibrator shakes the waste accumulated in the waste hopper, allowing it to be discharged more easily through the discharge channel.

[0018] 3. By setting a first filter device and a second filter device below the outlet of the feeding cylinder, the two devices have the same structure and are arranged in a cross manner. With the filter plate on the surface and the third slide groove and the second slider set on one side, the filter plate is inclined downward to facilitate the shaking of Chinese herbal raw materials. At the same time, the filter holes on the filter plates of the first filter device and the second filter device gradually increase in size from top to bottom according to the vertical position relationship, so as to achieve graded filtration according to the different sizes of Chinese herbal raw materials. At the same time, a collection plate is set below the filter plate. The collection plate collects through the collection chamber. The collection rod is set inside the collection chamber to pull out the filtered Chinese herbal raw materials for easy and quick collection. If raw materials are stuck in the fourth slide groove, they can be cleaned by pulling out the entire collection plate. Attached Figure Description

[0031] The first filter device 4 and the second filter device 5 have the same structure. The first filter device 4 includes a side plate 41, a material rack 42, a filter plate 43, a collection plate 44, a second slider 46, a reinforcing sleeve 47, a motor 48, and a cam 49. The side plate 41 is installed on the top of the base plate 1. The material rack 42 is arranged in two groups on one side of the side plate 41, with vertical spacing. The two ends of the material rack 42 near the side plate 41 are respectively provided with a third sliding groove 45 that is inclined to one side. The second slider 46 is slidably arranged in the third sliding groove 45. The side of the filter plate 43 away from the side plate 41 is inserted into the material rack 42 and is fixedly connected to the two second sliders 46. The filter plate 43 has multiple filter holes. The motor 48 is arranged on one side of the two second sliders 46 and is installed on the side of the material rack 42. The cam 49 is arranged on the output end of the motor 48. The second slider 46 extends out of the third sliding groove 45. The reinforcing sleeve 47 of the cam 49 is fitted with a face sleeve. The collecting plate 44 is slidably inserted into the bottom front of the material rack 42. The part of the collecting plate 44 inserted into the material rack 42 is located below the filter plate 43. Multiple crossbars 410 are provided at the bottom of the collecting plate 44. The crossbars 410 are installed on the material rack 42 to support the collecting plate 44. At the same time, multiple second support frames 411 are provided on the bottom two sides of the material rack 42 corresponding to one side of the side plate 41. The material rack 42 is supported by the second support frames 411 and the side plate 41. A collecting cavity 441 is opened on the collecting plate 44. A fourth sliding groove 444 communicating with the collecting cavity 441 is opened on the front of the collecting plate 44. A collecting rod 442 is provided in the collecting cavity 441. One end of the collecting rod 442 extending into the collecting cavity 441 is bent to form a collecting groove 443. The other end of the collecting rod 442 extends to the outside of the collecting plate 44 through the fourth sliding groove 444.

[0032] The principle of this invention: The cut Chinese herbal raw materials can be fed into the top of the feeding cylinder 2. Then, the second cylinder 18 on one side is opened, which drives the cover plate 17 at the output end to contact the top of the feeding cylinder 2 through the slides 16 on both sides. Then, the blower 171 on the cover plate 17 is opened. At this time, the two hooks 311 set on the crossbar 36 are disengaged from the first slider 310. When the blower 171 is in use, the first cylinder 14 connected to the feeding cylinder 2 at the bottom is also opened to realize the up and down swing of the feeding cylinder 2. With the help of multiple small vibrators 23 on the surface, the cut Chinese herbal raw materials inside are blown and small particles are separated, so that the small particles fall into the bottom cover 25 through the filter cover 241 at the bottom.

[0033] After internal filtration, the blower and small vibrator 23 are turned off. The second cylinder 18 is then turned on, causing the top cover to detach from the material cylinder 2 and move to the top. Then, the first cylinder 14 below is turned on, pushing the top of the material cylinder 2 downwards, causing the internal Chinese herbal raw materials to fall onto the first filter device 4. This causes the motor 48 on the first filter device 4 to turn on, driving the cam 49 at the output end to rotate. This pushes the reinforcing sleeves 47 on the second sliders 46 at both ends of the filter plate 43 backwards, allowing the filter plate 43 to slide up and down according to the tilt angle of the third slide groove 45. The upward force is electrically driven to move the cam 49 upwards, and the downward force is achieved by its own weight. The Chinese herbal raw materials filtered through the filter holes slide quickly, allowing the material to fall rapidly onto the filter plate 43 of the second filter device 5. After being filtered, the material falls onto the filter plate 43 below the first filter device 4, and then falls onto the filter plate 43 below the second filter device 5 after being filtered again. Finally, the unfiltered material falls into the collection hopper for collection.

[0034] The filtered raw materials fall onto the collection plate 44 through the filter holes. The Chinese medicine raw materials located in the collection chamber 441 can be pulled outward by the collection trough 443 driven by the collection rod 442 to achieve material discharge and collection.

[0035] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
