[0010] Preferably, the selection device also includes a dust collector connected to the air outlet end of the fan.
[0011] Preferably, the dust collector comprises a dust removal box and an atomizing nozzle arranged in the dust removal box.
[0012] The beneficial effects of adopting the technical solution of the utility model are:
[0013] The utility model allows small-volume medicinal materials, impurities and the like to be screened out through the screen, and light-weight debris is sucked into the fan through negative pressure suction, while heavier debris is collected in a waste box, so as to achieve better selection. A notch is provided on one side of the waste bin, one end of the screen partially extends out from the notch, shafts are provided on both side walls of one end of the waste bin close to the notch, and the hopper is connected through the shaft. The hopper includes a trapezoidal bottom plate, baffles connected to both sides of the bottom plate, and connecting ears connected to the baffles, and locking grooves for embedding the screen are provided on the inner sides of the two baffles, and the oblong holes provided on the connecting ears are connected to the shaft. When the hopper is connected to the waste bin, the end of the screen is embedded in the locking groove, and the end of the screen is located above the bottom plate, so that the screen is locked on the waste bin, and the selected "clean medicinal materials" are collected through the hopper; when the screen needs to be replaced, the hopper is first pulled horizontally away from the waste bin to make the end of the screen disengage from the locking groove, and then the material channel is rotated along the axis and lifted upward to remove the screen from the waste bin.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and do not limit the scope of the present invention.
[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] The specific embodiments are as follows:
[0023] Embodiment 1, as Figure 1-4 As shown, a negative pressure sorting device comprises a waste box 1, a fan 2, a screen 7 and a hopper. The waste box 1 is open at the upper end, and the screen 7 is detachably connected to the upper end. One side of the waste box 1 is connected to the fan 2 through an air duct.
[0024] A support platform 11 is provided near the upper opening of the inner wall of the waste box 1 for supporting the screen 7. A notch 12 is provided at the upper end of one side wall of the waste box 1, and the notch 12 allows the support platform 11 to leak out. The screen 7 is placed on the support platform 11 and the end thereof extends out from the notch 12.
[0025] A hopper is connected to one end of the waste bin 1 near the notch 12. The hopper includes a bottom plate 4, a baffle 5, and a connecting ear 6. The bottom plate 4 is trapezoidal. Two baffles 5 are provided and vertically connected to both sides of the bottom plate 4. The connecting ear 6 is connected to the end of the baffle 5. An oblong hole 61 is provided on the connecting ear 6, and a shaft 14 is provided outside the two side walls of the waste bin 1 adjacent to the notch 12. The shaft 14 passes through the oblong hole 61 so that the hopper is connected to the waste bin 1. Locking grooves 51 are provided on the inner sides of the two baffles 5. In this way, when the screen 7 is connected to the waste box 1, the hopper is tightly connected to the waste box 1, and the end of the screen 7 extends out of the waste box 1 and is embedded in the locking groove 51, so that the screen 7 and the waste box 1 are locked; when the screen 7 needs to be replaced, the hopper is pulled horizontally away from the waste box 1 through the cooperation of the oblong hole 61 and the shaft 14, so that the screen 7 is disengaged from the locking groove 51, and the hopper is rotated and lifted up to facilitate the removal of the screen 7.
[0026] When a negative pressure selection device according to the present embodiment is in use, the screen 7 is connected to the waste bin 1 and locked by the hopper. Medicinal materials are selected on the screen 7, and smaller miscellaneous medicinal materials fall into the waste bin 1 from the holes in the screen 7. The fan 2 is turned on, and due to the negative pressure suction, lighter debris and dust are sucked into the fan 2. Heavier debris falls into the waste bin 1, which is convenient for centralized treatment. In addition, the screen 7 is locked by the hopper and can be easily replaced to adapt to the selection of different medicinal materials, and has better practical applicability.
[0027] Furthermore, the hopper is in an inclined state when it is closely connected to the waste box 1. The bottom plate 4 of the hopper is below the screen 7, which is convenient for collecting the selected "clean medicinal materials" after sliding through the hopper.
[0028] Furthermore, a locking bolt 15 is provided on the shaft 14. After the screen 7 is connected to the waste bin 1, the hopper is locked by the locking bolt 15 to ensure the stability of the screen 7 during the selection process.
[0029] Furthermore, a limiting groove 13 is provided on the side wall of the waste box 1 above the support platform 11. The screen 7 is laterally inserted into the limiting groove 13, which limits the screen 7 up and down, further improving the stability of the screen 7 when in use.
[0030] Furthermore, the selection device is also provided with a dust collector 3. The dust collector 3 is connected to the air outlet end of the fan 2, and the light-weight debris and dust drawn by the fan 2 enter the dust collector to complete the dust removal box, thereby reducing the impact on the environment.
[0031] In this embodiment, the dust collector 3 includes a dust removal box and an atomizing nozzle arranged in the dust removal box. The atomizing nozzle sprays mist water, and debris and dust enter the dust removal box and run at high speed to collide with the mist water to achieve a dust removal effect.
[0032] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
