The medicine raking assembly 20 is arranged on the upper part of the medicine tray 10, and the driving assembly 30 and the air supply assembly 40 are installed on the edge of the medicine tray 10. The driving assembly 30 is used to drive the medicine raking assembly 20 to move back and forth to rake the medicine on the upper part of the medicine tray 10. When the medicine raking assembly 20 moves back and forth, the air supply assembly 40 is used to supply air to the inside of the medicine raking assembly 20 to cool the medicine raking assembly 20.

[0020] When drying the explosive agent, the agent to be dried is placed on the upper part of the medicine tray 10, and the driving component 30 is used to drive the rake component 20 to move back and forth along the upper part of the medicine tray 10, and then the agent is raked to flatten the agent. The flattened agent continues to be raked during the subsequent reciprocating movement of the rake component 20, thereby achieving uniform drying of the agent. When the rake component 20 moves back and forth, air is supplied to the inside of the rake component 20 through the air supply component 40, and the air flows along the inside of the rake component 20, thereby cooling the rake component 20, thereby preventing the rake component 20 from repeatedly rubbing against the medicine tray 10 during the reciprocating movement, causing excessive heat, thereby preventing the agent from burning or even exploding due to the influence of high heat, thereby improving the safety of the agent raking process.

[0021] See also Figure 1 and Figure 3 In one embodiment, the medicine rake assembly 20 includes a support plate 202 and a plurality of medicine rake teeth 201, the support plate 202 is arranged above the medicine tray 10 and distributed along the width direction of the medicine tray 10, a plurality of the medicine rake teeth 201 are fixedly arranged at the bottom of the support plate 202, a plurality of the medicine rake teeth 201 are sequentially spaced and distributed along the bottom of the support plate 202, and the bottoms of a plurality of the medicine rake teeth 201 are in contact with the upper surface of the medicine tray 10, the driving assembly 30 includes a motor 301, a screw rod 302, a guide rod 303 and a sleeve 304, the screw rod 302 is arranged on one side of the upper part of the medicine tray 10, and the guide rod 303 is arranged on the medicine tray On the other side of the upper part of the tray 10, the screw rod 302 is distributed in parallel with the guide rod 303, and the motor 301 is installed at one end of the screw rod 302 to drive the screw rod 302 to rotate.

[0022] Initially, the motor 301 drives the screw rod 302 to rotate forward, and the screw rod 302 and the corresponding sleeve 304 cooperate with each other to drive the support plate 202 and the plurality of raking teeth 201 to move in one direction along the upper part of the medicine tray 10 as a whole. When the plurality of raking teeth 201 move, they act on the upper surface of the medicine tray 10 and slide along the upper surface of the medicine tray 10, thereby raking the medicine. When the support plate 202 and the plurality of raking teeth 201 move to one end of the medicine tray 10, the motor 301 drives the screw rod 302 to rotate in the opposite direction. The threaded cooperation of the corresponding sleeve 304 drives the support plate 202 and the plurality of medicine raking teeth 201 to move as a whole along the upper part of the medicine containing plate 10 in another direction. When moving, the plurality of medicine raking teeth 201 act on the upper surface of the medicine containing plate 10 and slide in the opposite direction along the upper surface of the medicine containing plate 10 to realize the raking of the medicine again. In this way, the motor 301 drives the screw rod 302 to rotate alternately forward and reverse, thereby driving the support plate 202 and the plurality of medicine raking teeth 201 to move back and forth along the upper part of the medicine containing plate 10, realizing the repeated raking of the medicine, so that the medicine can be dried comprehensively and fully.

[0023] See also Figure 2 and Figure 3In one embodiment, the air supply assembly 40 includes a multi-stage telescopic tube 401, one end of the multi-stage telescopic tube 401 is connected to the side wall of the support plate 202, and the other end is connected to the edge of the medicine tray 10, the support plate 202 is provided with a first L-shaped air channel 2022, a second L-shaped air channel 2023 and a plurality of U-shaped air channels 2021, each group of the rake teeth 201 is provided with a V-shaped air channel 2011, and the plurality of U-shaped air channels 2021 are alternately distributed with the plurality of V-shaped air channels 2011, and the plurality of U-shaped air channels 2021 are alternately distributed with the plurality of V-shaped air channels 2011. The first L-shaped air duct 2021 is connected with several V-shaped air ducts 2011 in sequence end to end, the first L-shaped air duct 2022 and the second L-shaped air duct 2023 are respectively located at the two ends inside the support plate 202, one end of the second L-shaped air duct 2023 is connected with one group of the V-shaped air ducts 2011 at the edge, and the other end is connected with the inner cavity of the multi-stage telescopic tube 401, one end of the first L-shaped air duct 2022 extends to the side of the support plate 202, and the other end is connected with another group of the V-shaped air ducts 2011 at the edge.

[0024] When the screw rod 302 rotates forward, thereby driving the support plate 202 and the plurality of medicine rake teeth 201 to move in one direction along the upper part of the medicine receiving tray 10 as a whole, the support plate 202 pulls the multi-stage telescopic tube 401 to extend. When the multi-stage telescopic tube 401 extends, the outside air is drawn from the first L-shaped air passage 2022 into the V-shaped air passage 2011 corresponding to it, and then the air flows along the plurality of U-shaped air passages 2021 and the plurality of V-shaped air passages 2011, and finally enters the multi-stage telescopic tube 401 through the second L-shaped air passage 2023; when the screw rod 302 rotates reversely, thereby driving the support plate 202 and the plurality of medicine rake teeth 201 to move in another direction along the upper part of the medicine receiving tray 10 as a whole. When the multi-stage telescopic tube 401 moves in the opposite direction, the support plate 202 drives the multi-stage telescopic tube 401 to shorten. When the multi-stage telescopic tube 401 shortens, the air inside it is pressed from the second L-shaped airway 2023 to the corresponding V-shaped airway 2011, and then the air flows in the opposite direction along the internal flow of the plurality of U-shaped airways 2021 and the plurality of V-shaped airways 2011, and is finally discharged to the outside through the first L-shaped airway 2022; when the above-mentioned outside air flows along the plurality of U-shaped airways 2021 and the plurality of V-shaped airways 2011, the heat accumulated on the plurality of rake teeth 201 can be taken away, so as to realize the cooling treatment of the plurality of rake teeth 201, thereby improving the safety of the plurality of rake teeth 201 when raking medicine.

[0025] See also Figure 1 , Figure 3 as well as Figure 4In one embodiment, triangular blocks 205 are fixedly provided on opposite sides of the support plate 202, two groups of push rods 102 are fixedly provided on the side walls of the medicine tray 10, first sliders 305 are fixedly provided on the bottoms of the two groups of sleeves 304, second slide rails 204 are fixedly provided at both ends of the upper part of the support plate 202, two groups of the first sliders 305 are slidably matched with the two groups of the second slide rails 204, a first slide rail 203 is fixedly provided on the side wall of the support plate 202, a second slider 402 is fixedly provided at one end of the multi-stage telescopic tube 401, the second slider 402 is slidably matched with the first slide rail 203, and one side of the multi-stage telescopic tube 401 is connected to the second L-shaped airway 2023 through a hose 403.

[0026] When the screw rod 302 rotates forward to drive the support plate 202 and the plurality of raking teeth 201 to move to one end of the medicine tray 10, the triangular block 205 on one side of the support plate 202 acts on a group of push rods 102, and the group of push rods 102 acts on the inclined surface of the group of triangular blocks 205, thereby pushing the support plate 202 and the plurality of raking teeth 201 to move along the width direction of the medicine tray 10. When the support plate 202 moves, the first slide rail 203 slides compared to the second slide block 402, and the second slide rail 204 slides compared to the first slide block 305. Thereafter, the screw rod 302 rotates in the opposite direction to drive the support plate 202 and the plurality of raking teeth 201 to move in the opposite direction along the upper part of the medicine tray 10. At this time, since the support plate 202 and the plurality of raking teeth 201 move a certain distance in the width direction of the medicine tray 10, the raking route of the plurality of raking teeth 201 for the medicine changes; When the support plate 202 and the plurality of medicine-raking teeth 201 move in the opposite direction to the other end of the medicine holding tray 10, the triangular block 205 on the other side of the support plate 202 acts on another group of push rods 102, and the group of push rods 102 acts on the inclined surface of the group of triangular blocks 205 to push the support plate 202 and the plurality of medicine-raking teeth 201 to move in the opposite direction along the width direction of the medicine holding tray 10, thereby realizing the reset of the support plate 202 and the plurality of medicine-raking teeth 201, and then the screw rod 302 rotates forward again to drive the support plate 202 and the plurality of medicine-raking teeth 201 to move toward one end of the medicine holding tray 10 again. In this way, through the cooperation of the two groups of triangular blocks 205 and the two groups of push rods 102, the positions of the plurality of medicine-raking teeth 201 can be automatically adjusted, so that the raking route of the plurality of medicine-raking teeth 201 for the medicine is changed within one reciprocating movement cycle, thereby improving the raking effect of the medicine and improving the drying effect.

[0027] In one embodiment, the multi-stage telescopic tube 401 is made of metal material. When the multi-stage telescopic tube 401 is extended to drive the outside air to flow along the inside of the plurality of V-shaped airways 2011 and the inside of the plurality of U-shaped airways 2021, the flowing air drives the heat on the plurality of rake teeth 201 to the inside of the multi-stage telescopic tube 401. At this time, the heat is dissipated to the external environment through the metal tube wall of the extended multi-stage telescopic tube 401, thereby achieving timely heat dissipation and preventing the multi-stage telescopic tube 401 from pressing the heat back to the inside of the plurality of V-shaped airways 2011 again during the subsequent shortening process.

[0028] In the embodiment of the present invention, when drying the explosive agent, the agent to be dried is placed on the upper part of the medicine tray 10, and the driving component 30 is used to drive the medicine rake component 20 to move back and forth along the upper part of the medicine tray 10, and then the agent is raked to flatten the agent. The flattened agent continues to be raked during the subsequent reciprocating movement of the medicine rake component 20, thereby achieving uniform drying of the agent. When the medicine rake component 20 moves back and forth, air is supplied to the inside of the medicine rake component 20 through the air supply component 40, and the air flows along the inside of the medicine rake component 20, thereby cooling the medicine rake component 20. Compared with the prior art, during the process of drying and raking the explosive agent, the heat of the medicine rake component 20 can be effectively prevented, thereby preventing the agent from burning or even exploding due to the high heat of the medicine rake component 20, thereby improving the safety of the agent raking process.
