[0060] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0061] Embodiment 1

[0062] like Figure 1-Figure 10 As shown, in this embodiment, a wormwood drying device for processing wormwood sticks is provided, comprising a box body 1, a first conveyor belt 2 for spreading wormwood powder is transversely arranged inside the box body 1, a second conveyor belt 15 is arranged inside the box body 1 and below the first conveyor belt 2, the first conveyor belt 2 and the second conveyor belt 15 are both supported inside the box body 1 through a support shaft, a support shaft supporting the first conveyor belt 2 and the second conveyor belt 15 can adopt a tubular motor to provide power output for the rotational transportation of the first conveyor belt 2 and the second conveyor belt 15, the first conveyor belt 2 and the second conveyor belt 15 have opposite rotation directions, and a feed hopper 3 is fixedly installed on one side of the top of the box body 1, and a material shifting mechanism 4 for shifting the wormwood powder in the feed hopper 3 to the first conveyor belt 2 is arranged on the feed inlet 301;

[0063] Wherein, a plurality of tray units 16 for spreading wormwood powder are evenly arranged on the second conveyor belt 15, and the tray units 16 each include;

[0064] A fixed plate 1601, which is disposed on the second conveyor belt 15, and a plurality of strip-shaped bosses 1602 are arranged on the upper surface of the fixed plate 1601;

[0065] A movable plate 1603, wherein the movable plate 1603 is slidably connected to the fixed plate 1601 via a first spring 1604;

[0066] A plurality of support rods 1605, the plurality of support rods 1605 are evenly distributed on the movable plate 1603, the plurality of support rods 1605 and the plurality of bosses 1602 are alternately distributed, and the upper surfaces of the plurality of support rods 1605 and the plurality of bosses 1602 form a table surface for spreading the wormwood powder;

[0067] When the movable plate 1603 is slid upward, the upper surface of the support rod 1605 is higher than the upper surface of the boss 1602;

[0068] When the movable disk 1603 is slid downward, the upper surface of the support rod 1605 is lower than the upper surface of the boss 1602.

[0069] like Figure 5 and Figure 6 As shown, when the tray unit 16 is above the second conveyor belt 15, in order to drive the movable plate 1603 to slide up and down on the fixed plate 1601, support frames 18 are provided inside the box body 1 and on both sides of the second conveyor belt 15, and rails 1801 are provided on the two support frames 18, and multiple convex rails 1802 are distributed at intervals on the rails 1801, and slopes 1803 are provided at both ends of the multiple convex rails 1802;

[0070] Ear blocks 19 are provided on both sides of the movable plate 1603, and universal rollers 20 are provided below the ear blocks 19;

[0071] When the tray unit 16 moves above the second conveyor belt 15, the universal roller 20 rolls alternately on the track 1801 and the raised track 1802;

[0072] When the universal roller 20 rolls on the track 1801, the upper surface of the support rod 1605 is lower than the upper surface of the boss 1602;

[0073] When the universal roller 20 rolls on the convex rail 1802 , the upper surface of the support rod 1605 is higher than the upper surface of the boss 1602 .

[0074] like Figure 7-Figure 8 As shown, in order to make the fixed plate 1601 vibrate, the wormwood drying device for processing wormwood sticks also includes a vibration component 17, and the vibration component 17 includes a crossbeam 1701, and the crossbeam 1701 is fixed on the second conveyor belt 15. Two arc grooves 1702 are symmetrically provided on the crossbeam 1701, and the arc centers of the two arc grooves 1702 coincide with each other; the interior of the arc groove 1702 is slidably connected with a slider 1703 through a second spring 1704, and at the same time, the slider 1703 is fixedly connected to the bottom wall of the fixed plate 1601, as shown in FIG. Figure 7 and Figure 8 As shown, a second spring 1704 is disposed on both sides of the slider 1703. When the fixed plate 1601 is not subjected to force, the slider 1703 is located in the middle of the arc groove 1702 due to the spring pressure of the second spring 1704.

[0075] A lever 1705 is fixed to any ear block 19 on each movable disk 1603 , and a plurality of stoppers 1706 are fixed to the track 1801 on the same side of the lever 1705 . The lever 1705 is in movably contact with the plurality of stoppers 1706 .

[0076] The process of vibration component 17 generating vibration is as follows:

[0077] As the second conveyor belt 15 rotates, the tray unit 16 moves with the second conveyor belt 15, and as the tray unit 16 moves, the lever 1705 moves with it. During the movement, when the lever 1705 moves to contact with the stopper 1706, the lever 1705 deflects, and the slider 1703 slides inside the arc groove 1702, so that the fixed plate 1601 and the movable plate 1603 rotate as a whole by a moving angle. During the rotation, the lever 1705 gradually disengages from the stopper 1706. When the lever 1705 completely disengages from the stopper 1706, the fixed plate 1601 and the movable plate 1603 reciprocate under the elastic force of the second spring 1704.

[0078] When the universal roller 20 is on the convex rail 1802, the upper surface of the support rod 1605 is higher than the upper surface of the boss 1602, and after the fixed plate 1601 and the movable plate 1603 vibrate through the vibration assembly 17, the wormwood powder on the support rod 1605 falls onto the upper surface of the boss 1602;

[0079] When the universal roller 20 is on the track 1801, the upper surface of the support rod 1605 is lower than the upper surface of the boss 1602, and after the fixed plate 1601 and the movable plate 1603 vibrate through the vibration assembly 17, the wormwood powder on the boss 1602 falls onto the upper surface of the support rod 1605;

[0080] In this way, the position of the wormwood powder is repeatedly changed to turn the wormwood powder over, and since the boss 1602 and the support rod 1605 alternately support the wormwood powder, when the wormwood powder is on the boss 1602, the water vapor on the support rod 1605 can evaporate quickly. Similarly, when the wormwood powder is on the support rod 1605, the water vapor on the boss 1602 can evaporate quickly.

[0081] like Figure 1 As shown, in order to discharge the moisture in the dry area out of the box body 1, an air inlet slot 12 is opened on the side wall of one end of the box body 1, and an exhaust fan 13 is arranged on the box body 1.

[0082] In addition, if Figure 1 As shown, in order to discharge the dried mugwort powder from the box body 1 , a discharge hopper 14 is provided on the side wall of the box body 1 and at the blanking end of the second conveyor belt 15 .

[0083] Embodiment 2

[0084] like Figure 1 and Figure 3As shown, on the basis of the first embodiment, in this embodiment, a heating bottom plate 5 is respectively arranged between the upper layer and the lower layer of the first conveyor belt 2 and the second conveyor belt 15, the upper side opening of the heating bottom plate 5 is close to the lower surface of the upper layer of the corresponding first conveyor belt 2, and a heating component 6 is arranged inside the box body 1. The heating component 6 includes a heating box, and a heat cavity is arranged in the heating box. The gas in the heat cavity can be heated in the form of a heating pipe. A heating pipe 7 is arranged between the heating component 6 and the two heating bottom plates 5. The heating pipe 7 is connected to the two heating bottom plates 5 at the same time, and a blower 8 is arranged at the connection position between the heating pipe 7 and the heating component 6, as shown in FIG. Figure 3 As shown, when the blower 8 is running, the blower 8 introduces the high-temperature gas in the hot chamber into the heating pipe 7, and the high-temperature gas is introduced into the heating base plate 5 through the drainage of the heating pipe 7. The high-temperature gas entering the two heating base plates 5 can heat the top of the first conveyor belt 2 and the second conveyor belt 15 respectively. In this way, the wormwood powder spread on the first conveyor belt 2 and the tray unit 16 is heated, which accelerates the evaporation of moisture in the wormwood powder and improves the drying efficiency of the wormwood powder; the high-temperature gas entering the heating base plate 5 is discharged from the gap between the heating base plate 5 and the upper layer of the first conveyor belt 2 (second conveyor belt 15) into the box body 1, thereby increasing the temperature in the box body 1, which is beneficial to the drying of the wormwood powder. Figure 3 As shown, in order to circulate the gas in the hot cavity of the heating base plate 5 and the heating component 6, a heat return pipe 9 is provided at one end of the heating base plate 5 and the heating component 6 away from the heat supply pipe 7. The added heat return pipe 9 can return part of the gas in the heating base plate 5 to the hot cavity in the heating component 6, thereby promoting the circulation of the gas in the hot cavity of the heating base plate 5 and the heating component 6, which is beneficial to the recycling of heat.

[0085] The feed inlet 301 is opened at the bottom of the feed hopper 3, and the material dispensing mechanism 4 includes a rotating roller 401, a plurality of material dispensing grooves 402 and a motor 403. The rotating roller 401 is rotatably connected to the feed inlet 301; the plurality of material dispensing grooves 402 are circumferentially distributed on the side wall of the rotating roller 401; the motor 403 is fixedly installed on the side wall of the feed hopper 3, and the output shaft of the motor 403 is fixedly connected to one end of the rotating roller 401; when the motor 403 rotates with the rotating roller 401, the plurality of material dispensing grooves 402 are alternately connected to the feed inlet 301, and a certain amount of wormwood powder is dispensed onto the first conveyor belt 2.

[0086] Embodiment 3

[0087] like Figure 1 and Figure 2As shown, on the basis of the above embodiment, in order to speed up the drying efficiency of the wormwood powder on the first conveyor belt 2, a comb plate 10 is fixedly installed inside the box body 1 in this embodiment, and the comb teeth end of the comb plate 10 is close to the upper surface of the first conveyor belt 2. When the material selection groove 402 selects the wormwood powder in the feed hopper 3 to the first conveyor belt 2, as the first conveyor belt 2 rotates, the wormwood powder on the first conveyor belt 2 is combed and scraped by the comb plate 10, so that the wormwood powder is distributed in strips. The strip-shaped wormwood powder is formed in the gap between two adjacent comb teeth on the comb plate 10, and the strip-shaped distribution is laid on the first conveyor belt 2 parallel to the conveying direction of the first conveyor belt 2. In this way, the surface area of ​​the wormwood powder becomes larger, the efficiency of water evaporation is improved, which is beneficial to the drying efficiency of the wormwood powder on the first conveyor belt 2, and the preliminary drying of the wormwood powder is achieved.

[0088] like Figure 2 As shown, in order to guide the wormwood powder on the first conveyor belt 2 to the tray unit 16 on the second conveyor belt 15, a material guide plate 11 is fixedly installed on one side wall of the box body 1. The material guide plate 11 is located on the side of the blanking end of the first conveyor belt 2. A plurality of spaced convex ribs 1101 are arranged on the material guide plate 11, and the plurality of convex ribs 1101 are staggered with the comb teeth on the comb plate 10.

[0089] like Figure 2 As shown, in order to speed up the drying efficiency of the wormwood powder in the tray unit 16, a plurality of convex ribs 1101 are arranged at intervals on the material guide plate 11. After the wormwood powder falls onto the material guide plate 11, the convex ribs 1101 are set so that the wormwood powder slides along the intervals formed by the convex ribs 1101. In this way, the wormwood powder falling on the tray unit 16 is distributed more evenly, thus preventing the wormwood powder from falling concentratedly on the tray unit 16.

[0090] In addition, due to the presence of a spacing between two adjacent tray units 16, the material-dispensing mechanism 4 and the first conveyor belt 2 operate in an intermittent manner, that is, when the second conveyor belt 15 drives a tray unit 16 to move to directly below the material guide plate 11, the material-dispensing mechanism 4 and the first conveyor belt 2 operate, and the tray unit 16 moves out from under the material guide plate 11 and stops until the next tray unit 16 moves to directly below the material guide plate 11, and then the material-dispensing mechanism 4 and the first conveyor belt 2 operate again, thereby ensuring that the material guide plate 11 can guide the wormwood powder into the tray unit 16. In addition, the intermittent operation of the first conveyor belt 2 can also increase the time that the wormwood powder is on the first conveyor belt 2, which is conducive to better preliminary drying of the wormwood powder.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents.
