Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material processing equipment, in particular to a Chinese medicinal material air selection device. Background Art

[0002] In the process of processing Chinese herbal medicines, it is necessary to separate impurities and defective products with different weights and obvious surface quality differences. The existing technology uses image recognition technology, which monitors the shape, size and other characteristics of Chinese herbal medicines in real time through intelligent control, thereby realizing an automated screening process, or through an intelligent control system, automatically adjusts the screening angle and speed according to the parameters set by the user to achieve accurate screening effects. However, the purchase cost of this type of equipment is high and cannot meet the production and processing needs of small and medium-sized enterprises. The wind selection device commonly used by medicinal material processing enterprises now uses wind power to quickly screen Chinese medicinal materials. For example, the Chinese patent with publication number CN2387980Y discloses a variable frequency horizontal air selection machine, the left and right side panels of which are formed by cutting and folding a whole steel plate, and the lower half is made into a symmetrical inverted trumpet shape, which avoids the defect that the material is easily left in the box during air selection. However, in practical applications, this type of air selection device has the problem that, since the raw materials are uniformly fed through a vibrating hopper, the raw materials accumulate in the hopper and are easily blocked by the feed port, and since the bottom raw materials are easily squeezed by the upper raw materials, the discharge is unstable. The same wind force faces different discharge weights, and the air selection effect is different, so it is impossible to scientifically adjust the air volume and achieve an ideal screening effect. Therefore, the utility model aims to develop a new type of Chinese medicinal material air selection device to better meet actual needs. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0021] See also Figure 1 A Chinese medicinal material air separation device shown in the figure comprises a feed hopper 1, a conveyor belt 2, and an air separation box 3. The conveyor belt 2 is arranged at an angle, and is driven by a motor 8. A material separation cushion layer 7 is provided on the surface of the conveyor belt 2, and the material separation cushion layer 7 is preferably a wear-resistant rubber layer. The material separation cushion layer 7 is arranged in contact with the conveyor belt 2 and rotates with the conveyor belt 2. The material separation cushion layer 7 is adapted to the width of the conveyor belt 2. Baffles 13 are provided on both sides of the material separation cushion layer 7. Along the material conveying direction, a plurality of spaced material separation plates 14 are also provided on the conveyor belt 2. One end of the conveyor belt 2 is close to the feed hopper 1, and the other end is close to the air separation box 3; therefore, the Chinese medicinal materials in the feed hopper 1 fall onto the conveyor belt 2 at a uniform speed and enter a plurality of sections formed by the material separation cushion layer 7, the baffles 13 on both sides, and the material separation plates 14, thereby effectively preventing the accumulation of Chinese medicinal materials during the conveying process and the occurrence of uneven material entering the air separation box 3.

[0022] like Figure 2 As shown, as an improvement to the present embodiment, the baffles 13 on both sides of the material distribution cushion layer 7 are of a curled structure, combined with the wear-resistant rubber layer with greater friction at the bottom, so as to better prevent the materials in the interval from sliding further downward and causing accumulation, thereby better ensuring the uniform distribution of the Chinese herbal materials in each interval.

[0023] As an improvement to this embodiment, side plates 12 are provided on both sides of the conveyor belt 2, and the baffles 13 on both sides of the material distribution cushion layer 7 abut against the corresponding side plates 12. This prevents the baffles 13 from deforming and causing outward expansion, further improving durability.

[0024] like Figure 1 As shown, the bottom of the feed hopper 1 is provided with an inclined feed hopper 6, and the discharge port of the feed hopper 6 is close to or adapted to the width of the material distribution plate 14. This allows the Chinese herbal medicine to be evenly distributed along the width direction of the conveyor belt 2. As an improvement to this embodiment, the bottom of the feed hopper 1 is open, and an adjustment plate 15 is provided at the opening, such as Figure 3 As shown, one end of the adjustment plate 15 is hinged to the opening, and the other end of the adjustment plate 15 is connected to the lifting rod 16, so that the size of the opening can be adjusted by the lifting movement of the lifting rod 16, thereby adapting to the feeding needs of Chinese herbal medicines of different types and forms, and better ensuring the amount of Chinese herbal medicines in each interval on the conveyor belt 2.

[0025] In this embodiment, the air separation box 3 is connected to the conveyor belt 2 through a material receiving trough 9. The air separation box 3 is connected to a fan at one end close to the conveyor belt 2, and a plurality of discharge hoppers 11 are provided at the bottom of the air separation box 3. The Chinese herbal medicines are air-selected inside the air separation box 3, and enter different discharge hoppers 11 according to their own gravity to achieve material separation.

[0026] As an improvement to this embodiment, Figure 1 As shown, the top of the air separation box 3 is arched, with a dust collecting port 10 on the arched top, and a dust collecting hopper 4 is arranged above the dust collecting port 10. Thus, the dust generated during the air separation process is timely absorbed and processed, reducing the dust from floating around, which is beneficial to improving the environment, and reducing the adhesion of dust on the Chinese medicinal materials products, reducing the difficulty of subsequent processing of the Chinese medicinal materials.
