[0002] Chinese herbal medicine mainly refers to medicinal plants composed of roots, stems, leaves and fruits. In the early stage of Chinese herbal medicine planting, the seeds of Chinese herbal medicine need to be screened to remove the dust and small particles of inferior seeds that do not meet the requirements before subsequent processing.
[0003] At present, when screening seeds, the seeds in bags are manually opened and directly poured into a vibrating screen for screening. Although this method can complete the screening work, it is also impossible to clean the dirt, dust, and other substances attached to the seeds, which will pollute the working environment. At the same time, only a single type of seeds can be screened, and the work efficiency is low.
[0004] Therefore, it is necessary to provide a screening device for Chinese herbal medicine seeds to solve the above technical problems. Utility Model Content
[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a screening device for Chinese herbal medicine seeds to solve the problem that the current processing method cannot clean the dirt, dust, debris and other substances attached to the seeds, which will pollute the working environment. At the same time, it can only screen a single type of seeds, and the work efficiency is low.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A screening device for Chinese herbal medicine seeds comprises: a box body;
[0008] Feed ports are installed at intervals on the top surface of the box body, and there are two groups of feed ports. The lower part of the feed ports is connected with a material dividing mechanism, and the bottom of the material dividing mechanism is connected with a material guide plate through a material discharge plate. The bottom outlet of the material guide plate is located directly above the vibrating screen, and an impurity box is installed at the bottom of the vibrating screen.
[0009] In one embodiment, the material dividing mechanism is composed of an installation box, a partition plate, and a rotating shaft. The installation box is installed and connected to the inside of the box body. The top of the installation box is connected to the feed port, and the bottom is connected to the unloading plate. The installation box as a whole is a hollow cylindrical structure. A partition plate is provided inside the installation box. A plurality of partition plates are arranged in a circular array with the rotating shaft as the center. A seed placement area is provided between adjacent partition plates. The rotating shaft is electrically connected to the electric control box. A motor and a belt are installed inside the electric control box. The motor is used to control the rotation of the rotating shaft.
[0010] In one embodiment, a gap is left between the extended end of the partition plate and the inner circumferential surface of the installation box, the gap size is smaller than the size of the seeds, and the end of the extended end of the partition plate is an arc surface.
[0011] In one embodiment, the guide plate as a whole is in a downward spiral structure, the inflection point of the guide plate is processed with an arc, and a transparent plastic panel is installed on the front end surface of the guide plate.
[0012] In one embodiment, the rear end surface of the guide plate is connected to the exhaust fan through an exhaust pipe, three exhaust pipes are installed at intervals up and down, and the exhaust fan is connected to the collection box through a connecting pipe.
[0013] The beneficial effects of the utility model are as follows:
[0014] (1) The utility model drives the rotating shaft to rotate through the electric control box, and then drives the partition plate to rotate. As the space adjacent to the partition plate moves to below the feed port, the seeds fall into the placement area. When the seeds rotate and move to the top of the feed plate, the seeds lose the limit of the partition plate and enter the interior of the feed plate. The batch screening and dust removal of the seeds helps to improve the screening fineness and thus improve the screening effect.
[0015] (2) The seeds of the utility model enter the guide plate after the diversion treatment. As the guide plate moves downward along an inclined path, the dust and soil attached to the seeds are scattered during the movement. The dust is sucked from the exhaust pipe into the collection box for treatment through the exhaust fan, thereby preventing dust from polluting the working environment.

DETAILED DESCRIPTION
[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.
[0022] like Figure 1-Figure 2 As shown, the screening device for Chinese herbal medicine seeds provided by the utility model comprises: a box body 1, a feed port 2, an electric control box 3, a collection box 4, an exhaust fan 5, a vibrating screen 6, a material dividing mechanism 7, a material discharge plate 8, and a material guide plate 9;
[0023] like Figure 1-Figure 2 As shown, feed ports 2 are installed at intervals on the top surface of the box body 1, and the feed ports 2 are divided into two groups. The lower part of the feed ports 2 is connected with a dividing mechanism 7, and the dividing mechanism 7 is used for feeding unscreened seeds at intervals so that the dust in each batch of seeds can be effectively exposed and removed. The bottom of the dividing mechanism 7 is connected with a guide plate 9 through a discharge plate 8, and the bottom outlet of the guide plate 9 is located directly above the vibrating screen 6. An impurity box 61 is installed at the bottom of the vibrating screen 6, and the impurity box 61 is used to collect screened waste.
[0024] Preferably, in one embodiment, Figure 3-Figure 4 As shown, the material distribution mechanism 7 is composed of an installation box 71, a partition plate 72, and a rotating shaft 73. The installation box 71 is installed and connected to the inside of the box body 1. The top of the installation box 71 is connected to the feed port 2, and the bottom is connected to the unloading plate 8. The installation box 71 is a hollow cylindrical structure as a whole. A partition plate 72 is arranged inside the installation box 71. A plurality of partition plates 72 are arranged in a circular array with the rotating shaft 73 as the center. The seed placement area is between adjacent partition plates 72. The rotating shaft 73 is electrically connected to the electric control box 3. The electric control box 3 is equipped with a motor and a belt. The motor is used to control the rotation of the shaft 73. The belt is used to connect the two shafts 73. When working, the shaft 73 is driven to rotate by the electric control box 3, and then the partition plate 72 is driven to rotate. As the space adjacent to the partition plate 72 moves to below the feed port 2, the seeds fall into the placement area, and when they move to the top of the unloading plate 8 as they rotate, the seeds lose the limit of the partition plate 72 and enter the interior of the unloading plate 8, which helps to improve the screening fineness and thus improve the screening effect for seed batch screening and dust removal.
[0025] Preferably, in one embodiment, Figure 3-Figure 4 As shown, there is a gap between the extended end of the partition plate 72 and the inner circumferential surface of the installation box 71, the size of the gap is smaller than the size of the seeds, and the end of the extended end of the partition plate 72 is an arc surface.
[0026] Preferably, in one embodiment, Figure 3-Figure 4 As shown, the guide plate 9 is in a downward spiral structure as a whole, the inflection point of the guide plate 9 is processed with an arc, and a transparent plastic panel is installed on the front end surface of the guide plate 9.
[0027] Preferably, in one embodiment, Figure 1-Figure 3 As shown, the rear end face of the guide plate 9 is connected to the exhaust fan 5 through an exhaust pipe 51, and three exhaust pipes 51 are installed at upper and lower intervals. The exhaust fan 5 is connected to the collecting box 4 through a connecting pipe 41. When working, the seeds after diversion treatment enter the guide plate 9. As the guide plate 9 moves downward along the inclined path, the dust and soil attached to the guide plate will be scattered during the movement. The dust will be sucked from the exhaust pipe 51 into the collecting box 4 for treatment through the exhaust fan 5 to avoid dust pollution of the working environment.
[0028] Working principle of this utility model:
[0029] During operation, the electrical control box 3 drives the rotating shaft 73 to rotate, thereby driving the partition plate 72 to rotate. As the space adjacent to the partition plate 72 moves to below the feed port 2, the seeds fall into the placement area, and as they rotate and move to the top of the unloading plate 8, the seeds lose the limit of the partition plate 72 and enter the interior of the unloading plate 8. Batch screening and dust removal of seeds helps to improve the screening fineness and thus improve the screening effect. The seeds after diversion treatment enter the guide plate 9. As the guide plate 9 moves downward along the inclined path, the dust and soil attached to the seeds will be scattered during movement. The dust is drawn from the exhaust pipe 51 into the collection box 4 for treatment through the exhaust fan 5 to avoid dust pollution of the working environment. The seeds after dust removal fall into the vibrating screen 6 for screening, and small-particle inferior seeds enter the impurity box 61 from the sieve holes for collection and treatment.
[0030] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
