[0002] Hydrazine nitrile, also known as α-amino nitrile, is an important organic synthesis intermediate. α-amino nitrile has excellent properties in chemistry and biology, and has the potential for chiral structure. Therefore, it is also widely used in the fields of biology and medicine, such as the synthesis of antithrombotic drugs, anticancer drugs and analgesics. Hydrazine nitrile is in solid powder state at room temperature. In the process of producing and synthesizing other drugs, it is fed by a feeding mechanism.

Manual feeding may cause the risk of inhaling powder particles. At the same time, the solid powder in the packaging bag is squeezed and compacted. During the feeding process, the solid powder that is compacted into agglomerates cannot be fed, which easily blocks the input end of the feeder.

A protrusion 40 is arranged at the bottom of the first guide plate 11.

The outer side of the fourth transmission shaft 32 located inside the upper hopper 1 is provided with a second cam 39 that is adapted to the protrusion 40;

[0042] A crushing mechanism is provided on one side of the inner wall of the upper hopper 1, and the input end of the crushing mechanism corresponds to the output end of the first guide plate 11. The crushing mechanism includes a crushing bin 12 provided on one side of the inner wall of the upper hopper 1, and the crushing bin 12 is located directly above the output end of the upper hopper 1, and the output end of the lower filter plate 31 is located directly above the crushing bin 12. Two groups of first support shafts 35 and second support shafts 37 that penetrate the outside of the upper hopper 1 are symmetrically provided at both ends of the inner wall of the crushing bin 12, and crushing rollers 36 are symmetrically provided on the outer side of the first support shaft 35 and the second support shaft 37 located inside the crushing bin 12, and the same end of the first support shaft 35 and the second support shaft 37 are respectively provided with a second gear 34 and a first gear 33 that mesh with each other, and the input end of the first support shaft 35 is transmission-connected with a second drive motor 7, and a second synchronous transmission unit 8 is commonly provided on the outer sides of the second support shaft 37, the fourth transmission shaft 32 and the third transmission shaft 29;

[0043] The output end of the upper hopper 1 is provided with a discharge port 23, and the discharge port 23 is connected to a feed auger 4. A first drive motor 6 is provided at the bottom of the feed auger 4, and the feed auger 4 is used for feeding and conveying the secondary hydrazine nitrile.

[0044] The use process of the secondary hydrazine nitrile solid feeding device proposed in this embodiment is as follows: the bagged secondary hydrazine nitrile material to be fed is placed on the top of the first transmission roller 3, and the first synchronous transmission unit 2 and the external drive unit are used to drive the first transmission roller 3 and the second transmission roller 13 to rotate, and the bagged magnetic chain amino nitrile material is transported to the top of the upper hopper 1 by the rotation of the first transmission roller 3. When the bagged secondary hydrazine nitrile is displaced to the position of the cutter 17, the bottom of the bagged secondary hydrazine nitrile packaging bag is cut by the cutter 17, and as the packaging bag continues to move, the secondary hydrazine nitrile material falls from the bottom to the inside of the upper hopper 1;

[0045] At this time, both ends of the packaging bag are positioned and clamped by the support pillow 9 and the clamping roller 10, and the main body of the packaging bag is supported and conveyed by the second transmission roller 13, and the bottom of the packaging bag is completely cut open, so that the secondary hydrazine nitrile material falls from the bottom to the top of the end surface guide plate 21 and is guided to the top of the first guide plate 11. By cutting and unloading from the bottom of the packaging bag, the dust of the secondary hydrazine nitrile is reduced, and the packaging has a dust blocking effect;

[0046] Through the guiding effect of the first guide plate 11, the secondary hydrazine nitrile material falls into the interior of the feed filter plate 31;

[0047] At this time, the second driving motor 7 is started to drive the first support shaft 35 to rotate, thereby driving the second gear 34 to mesh and rotate with the first gear 33, and the second support shaft 37 is driven to rotate through the first gear 33, thereby causing the two groups of crushing rollers 36 outside the first support shaft 35 and the second support shaft 37 to rotate towards each other;

[0048] As the second support shaft 37 rotates, the fourth transmission shaft 32 and the third transmission shaft 29 synchronously connected through the second synchronous transmission unit 8 are driven to rotate accordingly;

[0049] The rotation of the third transmission shaft 29 drives the first cam 28 to rotate accordingly, thereby exerting an extrusion effect on the support rod 26 corresponding to the top of the first cam 28, so that the support rod 26 moves upward and drives the unloading clapper 25 to move upward. The unloading clapper 25 is located between the two sets of second transmission rollers 13, and then slaps the bottom of the packaging bag supported by the top of the second transmission roller 13. By adjusting the position structure of the first cam 28, the order in which the multiple sets of unloading clappers 25 slap upward is in the opposite direction of the movement of the packaging bag, thereby preventing the phenomenon of blocking the movement of the packaging bag and improving the slapping efficiency.

[0050] The rotation of the fourth transmission shaft 32 drives the second cam 39 to rotate, and then the first guide plate 11 on the top of the protrusion 40 is squeezed by the second cam 39 to cause a horizontal displacement as a whole. The horizontal displacement of the first guide plate 11 drives the lower filter plate 31 to follow the displacement as a whole, and then the secondary hydrazine nitrile material falling into the lower filter plate 31 is screened. With the displacement of the lower filter plate 31, the slider 30 is driven to move inside the first displacement groove 19 and stretch or compress the second spring 38, thereby achieving the vibration screening effect of the lower filter plate 31;

[0051] At this time, the powder particles fall to the bottom of the upper hopper 1 after being screened by the lower filter plate 31, and the agglomerated solids are displaced by the reciprocating vibration of the lower filter plate 31. The structural design of the inner inclined surface of the lower filter plate 31 causes the agglomerated solids to be displaced and fall to the top of the crushing bin 12.

[0052] The agglomerated solids enter the crushing bin 12 and are crushed and squeezed by two sets of relatively rotating crushing rollers 36, thereby achieving the crushing function. The crushed solid powders fall from the bottom of the crushing bin 12 to the inside of the upper hopper 1 again.

[0053] The hydrazine nitrile solid powder falling into the upper hopper 1 slides down to the position of the first cam 28 under the guidance of the bottom of the upper hopper 1. At this time, the first drive motor 6 is started to drive the feeding auger 4 to operate to transport the hydrazine nitrile solid powder inside the first cam 28, thereby completing the feeding function. Through the cooperation of various components, the multiple functions of automatic feeding, reducing dust, and filtering and crushing are realized.

[0054] The specific implementation of this embodiment is described above, but this embodiment is not limited to the above-mentioned specific implementation. The above-mentioned specific implementation is only illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of this embodiment, all of which are protected by this embodiment.
