[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model provides Figure 1-5 A multi-layer Chinese medicine drying device shown in the figure comprises a drying box body 4 and a base 3 arranged at the bottom end of the drying box body 4, an electric heating box 9 is arranged at the top end of the drying box body 4, and the electric heating box 9 is connected to the inside of the drying box body 4, a drying box door 1 is arranged at the front end of the drying box body 4, the drying box body 4 is rotatably connected to the left end of the drying box door 1 by a hinge, an exhaust pipe 5 is arranged at the bottom end of the drying box body 4, and the exhaust pipe 5 is connected to the inside of the drying box body 4, and a placement foot 2 is arranged at the four corners of the bottom end of the drying box body 4, a plurality of hollow racks 7 are arranged inside the drying box body 4, and the plurality of hollow racks 7 are arranged equidistantly from top to bottom inside the drying box body 4, and a drying tray 8 is placed on the hollow racks 7. When using the multi-layer Chinese medicine drying device, it is first necessary to place the multi-layer Chinese medicine drying The equipment is stably and securely placed on the ground through the placement feet 2 at the bottom of the base 3, and then the electric heating cabinet 9 needs to be connected to the power supply, and the closed drying box door 1 is opened. At this time, the front end of the drying box body 4 is completely exposed, and then the Chinese medicinal materials to be dried are placed in the drying storage tray 8, and the Chinese medicinal materials need to be evenly spread in the drying storage tray 8, so that the Chinese medicinal materials can be heated more evenly, and then the drying storage tray 8 containing the Chinese medicinal materials needs to be placed on the hollow storage rack 7 inside the drying box body 4, and then the drying box door 1 needs to be closed again, and then the closed drying box door 1 is fixed by the box door closing device 6, and then the multi-layer Chinese medicine drying equipment can be used to dry the Chinese medicinal materials in the drying storage tray 8.
[0023] like Figure 1 , Figure 2 and Figure 3As shown, a touch screen 11 is arranged inside the outer wall of the front end of the electric heating case 9, and a blower 10 is arranged at the center of the top of the electric heating case 9. The air outlet of the blower 10 is connected with the inside of the electric heating case 9. When the Chinese medicinal materials in the drying box 4 are dried, the exhaust pipe 5 at the bottom of the drying box 4 needs to be connected with the external exhaust gas collection pipe, and then the electric heating case 9 needs to be started through the touch screen 11, and the electric heating temperature of the electric heating case 9 needs to be controlled through the touch screen 11. At this time, the heating wire inside the electric heating case 9 will be energized and heated. At the same time, the blower 10 at the top of the electric heating case 9 will start to work, and the blower 10 will blow air into the electric heating case 9, so that the heat inside the electric heating case 9 The waste gas generated when drying the Chinese medicinal materials will be transported to the waste gas collection pipe through the exhaust pipe 5. After the Chinese medicinal materials are dried, the electric heating chassis 9 needs to be turned off so that the electric heating chassis 9 cannot generate heat. However, it is necessary to ensure that the blower 10 continues to blow air for a period of time, so that the inside of the drying box 4 can be quickly cooled down. After cooling down, the drying box door 1 is opened, and then the drying tray 8 on the hollow storage rack 7 is taken out, and then the dried Chinese medicinal materials in the drying tray 8 are poured out, and then new Chinese medicinal materials are dried.
[0024] like Figure 1 , Figure 4 and Figure 5As shown, the left and right ends and the rear end of the drying box body 4 are connected to the box door closing device 6, which includes a hand-tightening tightening sleeve 12, a closing clamp 13, an adjusting screw 14 and a U-shaped fixing frame 15. The U-shaped fixing frame 15 is sleeved and fixed on the left and right ends and the rear end outer wall of the drying box body 4. The adjusting screw 14 is welded on the right end of the U-shaped fixing frame 15 and located on the front end outer wall. The closing clamp 13 is arranged outside the adjusting screw 14. The front side of the closing clamp 13 is provided with a hand-tightening tightening sleeve 12. The hand-tightening tightening sleeve 12 is threadedly sleeved on the adjusting screw 14. The closing clamp 13 can rotate clockwise or counterclockwise on the outside of the adjusting screw 14. After the drying box door 1 is closed to the front end of the drying box body 4, the closing clamp 13 can be tightly attached to the front end outer wall of the drying box door 1. When the hand-tightening tightening sleeve 12 moves backward, it will push the closing clamp 13 backward. When the drying box door 1 is closed to the front end of the drying box body 4 and is ready to dry the Chinese medicinal materials inside the drying box body 4, in order to avoid the leakage of high-temperature air inside the drying box body 4 due to the loose closing of the drying box door 1, it is necessary to use the box door closing device 6 to close the drying box door 1 in the closed state. To lock the oven door 1, specifically, it is necessary to rotate the closing clamping plate 13 outside the adjusting screw 14 so that the closing clamping plate 13 is rotated to the left and extended state. At this time, the closing clamping plate 13 is located at the front side of the drying oven door 1 in the closed state. Then, it is necessary to slowly tighten the hand-tightening tightening sleeve 12. The hand-tightening tightening sleeve 12 will move backward on the outside of the adjusting screw 14 through the thread pushing action. In this way, the closing clamping plate 13 will be pushed backward through the hand-tightening tightening sleeve 12 until the closing clamping plate 13 is tightly pressed against the front end of the drying oven door 1 in the closed state. Then, the hand-tightening tightening sleeve 12 is continued to be rotated. The tightening sleeve 12 is tightened in a rearward direction so that the closing clamping plate 13 can always exert a tightening pressure on the drying box door 1 in the closed state. When the two door closing devices 6 are adjusted, the closing clamping plates 13 on the two devices respectively exert a tightening pressure in the rearward direction on both sides of the upper and lower sides of the center of the drying box door 1 in the closed state, thereby firmly locking the drying box door 1 at the front end of the drying box body 4, avoiding the drying box door 1 from being damaged or forcibly opened when being pulled forcefully, and also avoiding the leakage of high-temperature air inside the drying box body 4.
[0025] like Figure 1 , Figure 4 and Figure 5As shown, the box door closing device 6 also includes a buffer contact piece 16, a buffer rod 17, a buffer hole 18 and a buffer spring 19. The left end of the U-shaped fixing frame 15 is provided with a buffer hole 18 inside the front end. The opening direction of the buffer hole 18 faces forward. A buffer spring 19 is fixed inside the buffer hole 18. A buffer rod 17 is fixed at the front end of the buffer spring 19. A buffer contact piece 16 is provided at the front end of the buffer rod 17. The buffer contact piece 16 is located at the front side of the left end of the drying box body 4. The buffer rod 17 can move back and forth in the buffer hole 18. The buffer spring 19 can be compressed when the buffer rod 17 moves backward. When the buffer spring 19 is not subjected to force, the front end of the buffer rod 17 is located at the front side of the front end outer wall of the drying box door 1 in the closed state. When it is necessary to take out the dried Chinese medicinal materials in the drying box body 4, it is necessary to open the drying box door 1 so that the front end of the drying box body 4 is completely exposed, so that the dried Chinese medicinal materials in the drying box body 4 can be completely taken out. However, when the drying box door 1 is punched, If the pulling force for opening the drying box door 1 is too great, the drying box door 1 will directly collide with the left outer wall of the drying box body 4, which may easily cause damage to both. At this time, the door closing device 6 can play a buffering and protective role for both. Specifically, when the drying box door 1 is forcefully opened, the opening angle of the drying box door 1 is close to one hundred and sixty degrees. At this time, the buffer contact piece 16 will fit the outer wall of the drying box door 1 in the opened state. As the drying box door 1 continues to be opened, the buffer rod 17 will be pushed backward, and the buffer rod 17 will compress the buffer spring 19. The buffer spring 19 will have a buffering effect, thereby buffering the impact force generated when the drying box door 1 is forcefully opened. When the buffer spring 19 is fully compressed, the buffer rod 17 and the buffer contact piece 16 will prevent the drying box door 1 from continuing to open, thereby preventing the drying box door 1 from colliding with the left outer wall of the drying box body 4, thereby protecting the drying box body 4, the hinge and the drying box door 1.
