Description

Technical Field

[0001] The present invention relates to the technical field of drying processing, and specifically relates to a drying device and a drying method for millet seed treatment. Background Technique

[0002] Millet is a common cash crop in the north. It has the effects of clearing heat, quenching thirst, nourishing yin, tonifying the spleen, kidneys and stomach, promoting urination, and treating diarrhea. Generally, newly harvested seeds have a moisture content of up to 25% to 45%. They have a large respiratory intensity, generate a large amount of heat, and have a lot of moisture. The seeds are prone to heat and mildew, or are poisoned by alcohol produced by anaerobic respiration, or die due to freezing damage at low temperatures. When the seed moisture content is above 40% to 60%, the seeds will germinate. High-moisture seeds are conducive to the activity and reproduction of warehouse pests, which endanger the seeds. Therefore, it is necessary to dry them in time to reduce the seed moisture content to a safe level for packaging and storage to ensure the stability of seed storage.

[0003] The published patent No. CN209484964U discloses a dust-proof type green organic millet drying device. The gear drives the drying cylinder to rotate through the gear ring, so that the millet located in the drying cylinder is continuously turned over, ensuring the drying effect of the hot air pipe on the drying cylinder. Moreover, a dust collection cover and a dust suction cover are provided above the drying cylinder to discharge the dust and the dried gas located in the drying cylinder, greatly improving the drying quality of green organic millet, with a remarkable dust-proof effect and strong practicability. However, the following problems still exist in the actual use of the above patent: Although the gear of this dust-proof type green organic millet drying device drives the drying cylinder to rotate through the gear ring, so that the millet located in the drying cylinder is continuously turned over, ensuring the drying effect of the hot air pipe on the drying cylinder, it is not easy to control the temperature during the drying process of millet seeds. When the temperature is too high, a large amount of moisture on the seed surface will be lost, but the moisture inside the seeds is difficult to evaporate, resulting in uneven evaporation of moisture on the seed surface and inside, which may cause seed cracks and reduce the germination rate. When the seed drying temperature is low, the seed drying time is prolonged, thus reducing the seed drying efficiency.

[0004] Therefore, a drying device and a drying method for millet seed treatment are proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of the present invention is to provide a drying device and a drying method for foxtail millet seeds, so as to solve the problem proposed in the above background technology that it is not easy to control the temperature during the drying process of foxtail millet seeds. When the temperature is too high, a large amount of moisture on the surface of the seeds will be lost, but the moisture inside the seeds is difficult to evaporate, resulting in uneven evaporation of moisture on the surface and inside of the seeds, which may cause seed cracks and reduce the germination rate. When the drying temperature of the seeds is low, the drying time of the seeds is prolonged, thereby reducing the seed drying efficiency.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: A drying device and a drying method for foxtail millet seeds, including a circulating temperature control mechanism, and detection brackets installed on both sides of the circulating temperature control mechanism; An evenly mixing mechanism is arranged on the outer side of the circulating temperature control mechanism, and support legs are symmetrically arranged at the bottom of the evenly mixing mechanism; It also includes: The circulating temperature control mechanism includes drying air blowing pipes. The number of the drying air blowing pipes is three. Air outlet holes are formed on the surface of each drying air blowing pipe. First rotating gears are fixedly installed at both ends of each drying air blowing pipe; Among them, a cleaning ring is slidably connected to the outer side of the drying air blowing pipe, and a connecting bracket is fixedly installed on one side of the cleaning ring; Among them, a reciprocating sliding ring is fixedly installed between the connecting brackets, and dispersing conical blocks are symmetrically installed on both sides of the connecting brackets.

[0007] Preferably, a reciprocating rotating shaft is rotatably connected to the inside of the reciprocating sliding ring. A reciprocating slider is fixedly installed at the end of the reciprocating rotating shaft. First connecting pipes are rotatably connected to one side of the middle part of each first rotating gear. A circulating elbow is fixedly installed at the end of each first connecting pipe. A heating box is fixedly installed at the end of the circulating elbow.

[0008] By adopting the above technical solution, the air outlet holes on the surface of the drying air blowing pipes are used to evenly blow air into the inside of the mixing and drying box. The hot air blown out can quickly dry the moisture on the surface of the seeds. Utilizing the meshing connection between the first rotating gears and the second rotating gears, the rotation of the drying air blowing pipes can be realized, so as to dry the seeds in all directions, reduce the blowing dead angle, and improve the seed drying efficiency.

[0009] Preferably, the heating box is fixedly installed on the outer side of the detection bracket. A temperature detection probe is fixedly installed on one side inside the detection bracket. A heating wire is fixedly installed on one side inside the heating box. A circulating fan is fixedly installed on one side inside the heating box close to the heating wire.

[0010] By adopting the above technical solution, when drying seeds, by utilizing the characteristics that the reciprocating rotating shaft inside the reciprocating sliding ring and the reciprocating slider are slidably connected to the reciprocating chute on the surface of the reciprocating screw rod, the reciprocating motion of the reciprocating sliding ring can be realized. By driving the connecting bracket and the dispersing conical block to move through the reciprocating sliding ring, the agglomerated seeds can be dispersed, thereby improving the seed drying effect. At the same time, due to the movement of the dispersing conical block, compared with the prior art, it will not cause the seeds to be violently impacted, resulting in seed damage. It can disperse the adhered seeds while protecting the seeds, thereby improving the integrity of the seeds. The cleaning ring can clean the surface of the drying air duct to prevent seeds from adhering to the drying air duct and causing the blockage of the drying air duct.

[0011] Preferably, on one side of the detection bracket away from the temperature detection probe, an opening and closing bracket is fixedly installed. Inside one side of the opening and closing bracket, an opening and closing sliding disk is slidably connected. Around one side of the opening and closing sliding disk, electric telescopic rods are fixedly installed. The electric telescopic rods are fixedly connected to the opening and closing bracket. On one side of the middle of the opening and closing sliding disk, a second connecting pipe is fixedly installed. At the end of the second connecting pipe, a drying device is fixedly installed.

[0012] By adopting the above technical solution, when drying seeds, the temperature inside the mixing drying box is detected by the temperature detection probe inside the detection bracket, avoiding the phenomenon of uneven seed drying caused by too high temperature. When the temperature is too high, a large amount of moisture on the surface of the seeds will be lost, but the moisture inside the seeds is difficult to evaporate, resulting in uneven evaporation of moisture on the surface and inside of the seeds, which may cause seed cracks and reduce the germination rate. When the seed drying temperature is low, the seed drying time is prolonged, thereby reducing the seed drying efficiency. The mixing drying box is evenly and circularly heated by the heating wire and the circulating fan inside the heating box, and the circulating air is evenly distributed inside the mixing drying box, thereby improving the uniformity and drying efficiency of seed drying.

[0013] Preferably, opening and closing chutes are provided around the inside of the opening and closing sliding disk. Inside the opening and closing chutes, opening and closing sliding rods are fixedly installed. The outside of the opening and closing sliding rods is slidably connected with opening and closing sliding sleeves. On one side of the opening and closing sliding sleeves, opening and closing springs are fixedly installed. The inside of the opening and closing sliding sleeves is rotatably connected with opening and closing rotating rods. The opening and closing rotating rods are rotatably connected with the opening and closing bracket. On the outside of the opening and closing sliding sleeves, opening and closing baffles are fixedly installed. The opening and closing baffles are slidably connected with the opening and closing sliding disk.

[0014] By adopting the above technical solution, when it is necessary to cool down the inside of the mixing and drying oven, start the electric telescopic rod. While the electric telescopic rod contracts, it drives the opening and closing sliding disk to slide inside the opening and closing bracket. When the opening and closing rotating rod rotates, it can drive the opening and closing sliding sleeve and the opening and closing baffle to move relatively, opening the middle of the opening and closing sliding disk, so that the outside air enters the inside of the mixing and drying oven through the second connecting pipe and mixes with the drying hot air, quickly reducing the temperature inside the mixing and drying oven to the specified temperature, thereby improving the seed drying effect, ensuring the water content of the seeds, and increasing the germination rate of the seeds. While the hot air is circulating, the drying equipment can be used to absorb the water vapor in the hot air, thereby improving the drying effect.

[0015] Preferably, the uniform mixing mechanism includes a mixing and drying oven. One side of the middle of the mixing and drying oven is fixedly installed with a mixing motor. The output end of the mixing motor is fixedly connected with a reciprocating lead screw. The surface of the reciprocating lead screw is provided with a reciprocating chute, and the reciprocating chute is slidably connected with a reciprocating slider. The reciprocating lead screw is slidably connected with a reciprocating sliding ring.

[0016] By adopting the above technical solution, Preferably, both ends of the reciprocating lead screw are fixedly installed with second rotating gears, and the second rotating gears are meshed and connected with the first rotating gear. The outer side of the mixing and drying oven close to the first rotating gear is meshed and connected with a meshing tooth ring. The meshing tooth ring is rotatably connected with the mixing and drying oven. One side of each of the two meshing tooth rings is fixedly installed with a connecting ring.

[0017] By adopting the above technical solution, the mixing motor drives the reciprocating lead screw to rotate, thereby realizing the movement of the cleaning ring and the reciprocating sliding ring. At the same time, due to the characteristics of the second rotating gears on both sides of the reciprocating lead screw being meshed and connected with the first rotating gear, the rotation of the first rotating gear is realized. At the same time, due to the characteristics of the meshing connection between the first rotating gear and the meshing tooth ring, the meshing tooth ring rotates while driving the connecting ring and the rotating ring to rotate.

[0018] Preferably, one side of the connecting ring is fixedly installed with a rotating ring. A plurality of limiting baffles are fixedly installed between the two rotating rings. The limiting baffles are in close connection with the inner wall of the mixing and drying oven. A plurality of rotating brackets are fixedly installed between the two rotating rings. A rotating connecting shaft is fixedly installed between the two rotating brackets. A rolling shovel is fixedly installed on the outer side of the rotating connecting shaft. The inner part of the rotating ring is rotatably connected with a limiting disk, and the limiting disk is rotatably connected with the first rotating gear.

[0019] By adopting the above technical solution, the limiting baffles can stir the seeds inside the mixing and drying oven. At the same time, when the seeds fall, they drive the rotating connecting shaft and the rolling shovel to rotate. The rolling shovel further disperses the seeds, further improving the seed drying effect.

[0020] Preferably, the support legs are symmetrically installed on both sides of the bottom of the mixing and drying box. A discharge pipe is fixedly installed at the bottom of the mixing and drying box, and a feed pipe is fixedly installed at the top of the mixing and drying box. A feed hopper is fixedly installed at the top of the feed pipe. Sealing baffles are symmetrically and slidably connected to the inner sides of the mixing and drying box near the discharge pipe and the feed pipe, and handles are fixedly installed on the outer sides of the sealing baffles.

[0021] By adopting the above technical solution, the seeds to be dried are poured into the mixing and drying box through the feed pipe and the feed hopper at the top of the mixing and drying box. The dried seeds are discharged through the discharge pipe. The handles can be used to open and close the sealing baffles, improving the sealing performance of the entire mixing and drying box.

[0022] The drying method steps are as follows: Step 1: Use the mixing motor to drive the reciprocating lead screw to rotate, thereby realizing the movement of the cleaning ring and the reciprocating sliding ring. At the same time, due to the meshing connection between the second rotating gears on both sides of the reciprocating lead screw and the first rotating gear, the rotation of the first rotating gear is realized. Also, due to the meshing connection between the first rotating gear and the meshing tooth ring, when the meshing tooth ring rotates, it drives the connecting ring and the rotating ring to rotate. The limiting baffle can stir the seeds inside the mixing and drying box. At the same time, when the seeds fall, it drives the rotating connecting shaft and the tumbling shovel to rotate, and the tumbling shovel further disperses the seeds, further improving the seed drying effect. The seeds to be dried are poured into the mixing and drying box through the feed pipe and the feed hopper at the top of the mixing and drying box. The dried seeds are discharged through the discharge pipe. The handles can be used to open and close the sealing baffles, improving the sealing performance of the entire mixing and drying box; Step 2: Use the air outlet holes on the surface of the drying air pipe to blow air evenly inside the mixing and drying box. By blowing hot air, the moisture on the surface of the seeds can be quickly dried. Due to the meshing connection between the first rotating gear and the second rotating gear, the rotation of the drying air pipe can be realized, thereby drying the seeds in all directions, reducing the blowing dead angle, and improving the seed drying efficiency. When drying the seeds, due to the sliding connection between the reciprocating rotating shaft and the reciprocating slider inside the reciprocating sliding ring and the reciprocating sliding groove on the surface of the reciprocating lead screw, the reciprocating movement of the reciprocating sliding ring can be realized. The connecting bracket and the dispersing conical block are driven by the reciprocating sliding ring to move, which can disperse the agglomerated seeds, thereby improving the seed drying effect. At the same time, compared with the prior art, when the dispersing conical block moves, the seeds will not be violently impacted, resulting in seed damage. It can disperse the adhered seeds while protecting the seeds, thereby improving the integrity of the seeds. The cleaning ring can clean the surface of the drying air pipe to prevent seeds from adhering to the drying air pipe and causing blockage of the drying air pipe; Step 3: When drying the seeds, the temperature inside the mixing drying box is detected by the temperature detection probe inside the detection bracket to avoid uneven drying of the seeds caused by excessive temperature. When the temperature is too high, a large amount of moisture on the surface of the seeds will be lost, but the moisture inside the seeds is difficult to evaporate, resulting in uneven evaporation of moisture on the surface and inside of the seeds, which may cause seed cracks and reduce the germination rate. When the seed drying temperature is low, the seed drying time is prolonged, thus reducing the seed drying efficiency. The mixing drying box is uniformly heated in a circulating manner through the heating wire and the circulating fan inside the heating box, and the circulating air is evenly distributed inside the mixing drying box, thereby improving the uniformity and drying efficiency of seed drying. When it is necessary to cool the inside of the mixing drying box, the electric telescopic rod is started. When the electric telescopic rod contracts, it drives the opening and closing sliding plate to slide inside the opening and closing bracket. When the opening and closing rotating rod rotates, it can drive the opening and closing sliding sleeve and the opening and closing baffle to move relatively, opening the middle of the opening and closing sliding plate, so that the outside air enters the inside of the mixing drying box through the second connecting pipe and mixes with the drying hot air, and the temperature inside the mixing drying box can be quickly reduced to the specified temperature, thereby improving the seed drying effect, ensuring the water content of the seeds, and increasing the germination rate of the seeds. During the hot air circulation, the drying equipment can be used to absorb the water vapor in the hot air, thereby improving the drying effect.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: For the drying equipment and drying method for foxtail millet seeds, the hot air blown out can quickly dry the moisture on the surface of the seeds. By using the characteristic of meshing connection between the first rotating gear and the second rotating gear, the rotation of the drying air pipe can be realized, so as to dry the seeds in all directions, reduce the blowing dead angle, and improve the seed drying efficiency. The seeds to be dried are poured into the mixing drying box through the feed pipe and the feed hopper at the top of the mixing drying box, and the dried seeds are discharged through the discharge pipe. The handle can be used to expand and close the sealing baffle, improving the sealing performance of the entire mixing drying box. The specific content is as follows: 1. By setting up a circulating temperature control mechanism, not only can the air outlet holes on the surface of the drying air duct be used to evenly blow air into the internal part of the mixing material drying box, and the hot air blown out can quickly dry the moisture on the surface of the seeds. Utilizing the meshing connection between the first rotating gear and the second rotating gear, the rotation of the drying air duct can be realized, thereby drying the seeds in all directions, reducing the dead angle of blowing, and improving the efficiency of seed drying. When drying the seeds, by using the reciprocating rotating shaft and reciprocating slider inside the reciprocating sliding ring, which are slidably connected to the reciprocating sliding groove on the surface of the reciprocating lead screw, the reciprocating movement of the reciprocating sliding ring can be realized. By driving the connecting bracket and the dispersing conical block to move through the reciprocating sliding ring, the agglomerated seeds can be dispersed, thereby improving the effect of seed drying. At the same time, compared with the prior art, the movement of the dispersing conical block will not cause the seeds to be violently impacted, resulting in seed damage. It can disperse the adhered seeds while protecting the seeds, thereby improving the integrity of the seeds. The surface of the drying air duct can be cleaned through the cleaning ring to prevent seeds from adhering to the drying air duct and causing blockage of the drying air duct. When drying the seeds, the temperature inside the mixing material drying box is detected through the temperature detection probe inside the detection bracket, avoiding the phenomenon of uneven seed drying caused by too high temperature. When the temperature is too high, a large amount of moisture on the surface of the seeds will be lost, but the moisture inside the seeds is difficult to evaporate, resulting in uneven evaporation of moisture on the surface and inside of the seeds, which may cause seed cracks and reduce the germination rate. When the seed drying temperature is low, the drying time of the seeds is prolonged, thereby reducing the efficiency of seed drying. The mixing material drying box is evenly heated in a circulating manner through the heating wire and circulating fan inside the heating box. The circulating air is evenly distributed inside the mixing material drying box, thereby improving the uniformity and drying efficiency of seed drying. When it is necessary to cool the inside of the mixing material drying box, the electric telescopic rod is started. When the electric telescopic rod contracts, it drives the opening and closing sliding disk to slide inside the opening and closing bracket. When the opening and closing rotating rod rotates, it can drive the opening and closing sliding sleeve and the opening and closing baffle to move relatively, opening the middle of the opening and closing sliding disk, so that the outside air enters the inside of the mixing material drying box through the second connecting pipe and mixes with the drying hot air, and the temperature inside the mixing material drying box can be quickly reduced to the specified temperature, thereby improving the effect of seed drying, ensuring the moisture content of the seeds, and improving the germination rate of the seeds. While the hot air is circulating, the drying device can be used to absorb the water vapor in the hot air, thereby improving the drying effect; 2. By setting up a uniform mixing mechanism, not only can the mixing motor drive the reciprocating lead screw to rotate, thereby realizing the movement of the cleaning ring and the reciprocating sliding ring, but also, due to the meshing connection between the second rotating gears on both sides of the reciprocating lead screw and the first rotating gear, the rotation of the first rotating gear is achieved. At the same time, by virtue of the meshing connection between the first rotating gear and the meshing tooth ring, when the meshing tooth ring rotates, it drives the connecting ring and the rotating ring to rotate. The limit baffle can stir the seeds inside the mixing and drying box. Meanwhile, when the seeds fall, it drives the rotating connecting shaft and the tumbling shovel to rotate. The tumbling shovel further disperses the seeds, further improving the seed drying effect. The seeds to be dried are poured into the mixing and drying box through the feed pipe and the feed hopper at the top of the mixing and drying box. The dried seeds are discharged through the discharge pipe. The handle can be used to open and close the sealing baffle, improving the sealing performance of the entire mixing and drying box.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 5, the present invention provides a technical solution: a drying device and a drying method for foxtail millet seeds, including a circulating temperature control mechanism 1, and detection brackets 113 installed on both sides of the circulating temperature control mechanism 1. An evenly mixing mechanism 2 is arranged on the outer side of the circulating temperature control mechanism 1, and support legs 214 are symmetrically arranged at the bottom of the evenly mixing mechanism 2. The circulating temperature control mechanism 1 includes drying air blowing pipes 101, and the number of drying air blowing pipes 101 is three. Air outlet holes 102 are formed on the surface of the drying air blowing pipes 101. First rotating gears 103 are fixedly installed at both ends of each drying air blowing pipe 101. Among them, a cleaning ring 104 is slidably connected to the outer side of the drying air blowing pipe 101. A connecting bracket 105 is fixedly installed on one side of the cleaning ring 104. Among them, a reciprocating sliding ring 107 is fixedly installed between the connecting brackets 105. Scattering conical blocks 106 are symmetrically installed on both sides of the connecting bracket 105. A reciprocating rotating shaft 108 is rotatably connected to the inside of the reciprocating sliding ring 107. A reciprocating slider 109 is fixedly installed at the end of the reciprocating rotating shaft 108.

A circulating elbow 111 is fixedly installed at the end of the first connecting pipe 110. A heating box 112 is fixedly installed at the end of the circulating elbow 111. By using the air outlet holes 102 on the surface of the drying air blowing pipes 101 to evenly blow air into the inside of the mixing and drying box 201, the moisture on the surface of the seeds can be quickly dried by blowing hot air. By utilizing the meshing connection between the first rotating gear 103 and the second rotating gear 205, the rotation of the drying air blowing pipe 101 can be realized, so as to blow-dry the seeds in all directions, reduce the blowing dead angle, and improve the efficiency of seed drying. When drying the seeds, by utilizing the reciprocating movement of the reciprocating rotating shaft 108 and the reciprocating slider 109 inside the reciprocating sliding ring 107 and the reciprocating sliding groove 204 on the surface of the reciprocating screw rod 203, the reciprocating movement of the reciprocating sliding ring 107 can be realized. By driving the connecting bracket 105 and the scattering conical block 106 to move through the reciprocating sliding ring 107, the agglomerated seeds can be scattered, thereby improving the effect of seed drying. At the same time, compared with the prior art, the movement of the scattering conical block 106 will not cause the seeds to be violently impacted, resulting in seed damage. It can scatter the adhered seeds while protecting the seeds, thereby improving the integrity of the seeds. The surface of the drying air blowing pipe 101 can be cleaned by the cleaning ring 104 to avoid the phenomenon that the seeds adhere to the drying air blowing pipe 101 and cause the blockage of the drying air blowing pipe 101.

[0028] Please refer to Figures 5 - 8, the heating box 112 is fixedly installed on the outside of the detection bracket 113. On one side inside the detection bracket 113, a temperature detection probe 114 is fixedly installed. On one side inside the heating box 112, a heating wire 115 is fixedly installed. On one side inside the heating box 112 near the heating wire 115, a circulation fan 116 is fixedly installed. On the side of the detection bracket 113 away from the temperature detection probe 114, an opening and closing bracket 117 is fixedly installed. Inside the opening and closing bracket 117, an opening and closing sliding disc 118 is slidably connected. Around one side of the opening and closing sliding disc 118, electric telescopic rods 119 are fixedly installed. The electric telescopic rods 119 are fixedly connected to the opening and closing bracket 117. On one side in the middle of the opening and closing sliding disc 118, a second connecting pipe 120 is fixedly installed. At the end of the second connecting pipe 120, a drying device 121 is fixedly installed. Inside the opening and closing sliding disc 118, opening and closing sliding grooves 122 are formed around the perimeter. Inside the opening and closing sliding grooves 122, opening and closing sliding rods 123 are fixedly installed. On the outside of the opening and closing sliding rods 123, opening and closing sliding sleeves 124 are slidably connected. On one side of the opening and closing sliding sleeves 124, opening and closing springs 125 are fixedly installed. On the inner side of the opening and closing sliding sleeves 124, opening and closing rotating rods 126 are rotatably connected. The opening and closing rotating rods 126 are rotatably connected to the opening and closing bracket 117. On the outside of the opening and closing sliding sleeves 124, opening and closing baffles 127 are fixedly installed. The opening and closing baffles 127 are slidably connected to the opening and closing sliding disc 118. When drying seeds, the temperature detection probe 114 inside the detection bracket 113 is used to detect the temperature inside the mixing drying box 201, avoiding the phenomenon of uneven seed drying caused by too high temperature. When the temperature is too high, a large amount of water on the surface of the seeds will be lost, but the water inside the seeds is difficult to evaporate, resulting in uneven evaporation of water on the surface and inside of the seeds, which may cause seed cracks and reduce the germination rate. When the seed drying temperature is low, the seed drying time is prolonged, thus reducing the seed drying efficiency. The heating wire 115 and the circulation fan 116 inside the heating box 112 are used for uniform circulating heating of the mixing drying box 201. The circulating air is evenly distributed inside the mixing drying box 201, thereby improving the uniformity and drying efficiency of seed drying. When it is necessary to cool down the inside of the mixing drying box 201, the electric telescopic rods 119 are started. While the electric telescopic rods 119 contract, they drive the opening and closing sliding disc 118 to slide inside the opening and closing bracket 117. When the opening and closing rotating rods 126 rotate, they can drive the opening and closing sliding sleeves 124 and the opening and closing baffles 127 to move relative to each other, opening the middle of the opening and closing sliding disc 118, enabling the outside air to enter the inside of the mixing drying box 201 through the second connecting pipe 120 and mix with the drying hot air, quickly reducing the temperature inside the mixing drying box 201 to the specified temperature, thereby improving the seed drying effect, ensuring the water content of the seeds, and increasing the germination rate of the seeds. While the hot air is circulating, the drying device 121 can be used to absorb the water vapor in the hot air, thereby improving the drying effect.

[0029] Please refer toFigure 1 , Figures 7 - 11 , the uniform mixing mechanism 2 includes a mixing and drying box 201. One side of the middle of the mixing and drying box 201 is fixedly installed with a mixing motor 202. The output end of the mixing motor 202 is fixedly connected with a reciprocating lead screw 203. A reciprocating chute 204 is formed on the surface of the reciprocating lead screw 203. The reciprocating chute 204 is slidably connected with a reciprocating slider 109. The reciprocating lead screw 203 is slidably connected with a reciprocating sliding ring 107. Both ends of the reciprocating lead screw 203 are fixedly installed with second rotating gears 205. The second rotating gears 205 are meshed with the first rotating gear 103. A meshing tooth ring 206 is meshed outside the mixing and drying box 201 near the first rotating gear 103. The meshing tooth ring 206 is rotatably connected with the mixing and drying box 201. A connecting ring 207 is fixedly installed on one side of each of the two meshing tooth rings 206. A rotating ring 208 is fixedly installed on one side of the connecting ring 207. A plurality of limiting baffles 209 are fixedly installed between the two rotating rings 208.

By driving the reciprocating lead screw 203 to rotate by the mixing motor 202, the movement of the cleaning ring 104 and the reciprocating sliding ring 107 is realized. At the same time, due to the meshing connection between the second rotating gears 205 on both sides of the reciprocating lead screw 203 and the first rotating gear 103, the rotation of the first rotating gear 103 is realized. At the same time, due to the meshing connection between the first rotating gear 103 and the meshing tooth ring 206, when the meshing tooth ring 206 rotates, it drives the connecting ring 207 and the rotating ring 208 to rotate. The seeds inside the mixing and drying box 201 can be stirred by the limiting baffles 209. At the same time, when the seeds fall, the rotating connecting shaft 211 and the tumbling shovel 212 are driven to rotate. The seeds are secondarily scattered by the tumbling shovel 212, further improving the seed drying effect.

[0030] Please refer to Figures 11 - 12, the limiting disk 213 is rotatably connected to the first rotating gear 103. The support legs 214 are symmetrically installed on both sides of the bottom of the mixing and drying box 201.

A handle 219 is fixedly installed on the outer side of the sealing baffle 218. The seeds to be dried are poured into the mixing and drying box 201 through the feed pipe 216 and the feed hopper 217 at the top of the mixing and drying box 201. The dried seeds are discharged through the discharge pipe 215. The opening and closing of the sealing baffle 218 can be realized through the handle 219, improving the sealing performance of the entire mixing and drying box 201.

[0031] Working principle: Before using this drying equipment and drying method for foxtail millet seeds, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 12 As shown, first, the mixing motor 202 drives the reciprocating lead screw 203 to rotate, thereby realizing the movement of the cleaning ring 104 and the reciprocating sliding ring 107. At the same time, due to the meshing connection between the second rotating gears 205 on both sides of the reciprocating lead screw 203 and the first rotating gear 103, the rotation of the first rotating gear 103 is realized. At the same time, due to the meshing connection between the first rotating gear 103 and the meshing tooth ring 206, when the meshing tooth ring 206 rotates, it drives the connecting ring 207 and the rotating ring 208 to rotate. The limiting baffle 209 can stir the seeds inside the mixing and drying box 201. At the same time, when the seeds fall, it drives the rotating connection shaft 211 and the tumbling shovel 212 to rotate. The tumbling shovel 212 further disperses the seeds, further improving the seed drying effect. The seeds to be dried are poured into the mixing and drying box 201 through the feed pipe 216 and the feed hopper 217 at the top of the mixing and drying box 201. The dried seeds are discharged through the discharge pipe 215. The opening and closing of the sealing baffle 218 can be realized through the handle 219, improving the sealing performance of the entire mixing and drying box 201.

[0032] Secondly, use the air outlet holes 102 on the surface of the drying air duct 101 to blow air evenly into the inside of the mixing drying box 201. The hot air blown out can quickly dry the moisture on the surface of the seeds. By using the meshing connection between the first rotating gear 103 and the second rotating gear 205, the rotation of the drying air duct 101 can be realized, so as to dry the seeds in all directions, reduce the dead angle of blowing, and improve the efficiency of seed drying. When drying the seeds, by using the reciprocating rotating shaft 108 and the reciprocating slider 109 inside the reciprocating sliding ring 107, which are slidably connected to the reciprocating chute 204 on the surface of the reciprocating lead screw 203, the reciprocating movement of the reciprocating sliding ring 107 can be realized. By driving the connecting bracket 105 and the dispersing conical block 106 to move through the reciprocating sliding ring 107, the agglomerated seeds can be dispersed, thus improving the effect of seed drying. At the same time, compared with the prior art, the movement of the dispersing conical block 106 will not cause the seeds to be violently impacted, resulting in seed damage. It can disperse the adhered seeds while protecting the seeds, thus improving the integrity of the seeds. The cleaning ring 104 can clean the surface of the drying air duct 101 to prevent seeds from adhering to the drying air duct 101 and causing blockage of the drying air duct 101.

[0033] Finally, when drying the seeds, the temperature inside the mixing drying box 201 is detected by the temperature detection probe 114 inside the detection bracket 113 to avoid uneven seed drying caused by too high temperature. When the temperature is too high, a large amount of moisture on the surface of the seeds will be lost, but the moisture inside the seeds is difficult to evaporate, resulting in uneven evaporation of moisture on the surface and inside of the seeds, which may cause seed cracks and reduce the germination rate. When the seed drying temperature is low, the seed drying time is prolonged, thus reducing the efficiency of seed drying. The mixing drying box 201 is evenly and circularly heated by the heating wire 115 and the circulation fan 116 inside the heating box 112. The circulating air is evenly distributed inside the mixing drying box 201, thereby improving the uniformity and drying efficiency of seed drying. When it is necessary to cool the inside of the mixing drying box 201, start the electric telescopic rod 119. When the electric telescopic rod 119 contracts, it drives the opening and closing sliding disk 118 to slide inside the opening and closing bracket 117. When the opening and closing rotating rod 126 rotates, it can drive the opening and closing sliding sleeve 124 and the opening and closing baffle 127 to move relatively, opening the middle of the opening and closing sliding disk 118, so that the outside air enters the inside of the mixing drying box 201 through the second connecting pipe 120 and mixes with the drying hot air, quickly reducing the temperature inside the mixing drying box 201 to the specified temperature, thereby improving the effect of seed drying, ensuring the water content of the seeds, and increasing the germination rate of the seeds. During the hot air circulation, the drying device 121 can be used to absorb the water vapor in the hot air, thereby improving the drying effect.

10. A drying method for a drying device used for foxtail millet seeds, which uses a drying device for foxtail millet seeds as described in claim 9, and is characterized in that, The drying method steps are as follows: Step 1: Use the mixing motor (202) to drive the reciprocating lead screw (203) to rotate, thereby realizing the movement of the cleaning ring (104) and the reciprocating sliding ring (107). At the same time, through the engagement connection between the second rotating gears (205) on both sides of the reciprocating lead screw (203) and the first rotating gear (103), the rotation of the first rotating gear (103) is realized. At the same time, using the engagement connection between the first rotating gear (103) and the meshing tooth ring (206), when the meshing tooth ring (206) rotates, it drives the connecting ring (207) and the rotating ring (208) to rotate. The limit baffle (209) can stir the seeds inside the mixing and drying box (201). At the same time, when the seeds fall, it drives the rotating connecting shaft (211) and the tumbling shovel (212) to rotate. The tumbling shovel (212) further disperses the seeds to improve the seed drying effect. Pour the seeds to be dried into the mixing and drying box (201) through the feed pipe (216) and the feed hopper (217) at the top of the mixing and drying box (201). The dried seeds are discharged through the discharge pipe (215). The handle (219) can realize the unfolding and closing of the sealing baffle (218) to improve the sealing performance of the entire mixing and drying box (201); Step 2: Use the air outlet holes (102) on the surface of the drying air pipe (101) to blow air evenly inside the mixing and drying box (201). By blowing hot air, the moisture on the surface of the seeds can be quickly dried. Using the engagement connection between the first rotating gear (103) and the second rotating gear (205), the rotation of the drying air pipe (101) can be realized, thereby drying the seeds in all directions, reducing the blowing dead angle, and improving the seed drying efficiency. When drying the seeds, using the characteristics that the reciprocating rotating shaft (108) and the reciprocating slider (109) inside the reciprocating sliding ring (107) are slidably connected to the reciprocating sliding groove (204) on the surface of the reciprocating lead screw (203), the reciprocating movement of the reciprocating sliding ring (107) can be realized. The reciprocating sliding ring (107) drives the connecting bracket (105) and the dispersing conical block (106) to move, which can disperse the agglomerated seeds, thereby improving the seed drying effect. At the same time, compared with the prior art, the movement of the dispersing conical block (106) will not cause the seeds to be violently impacted and damaged. It can disperse the adhered seeds while protecting the seeds, thereby improving the integrity of the seeds. The cleaning ring (104) can clean the surface of the drying air pipe (101) to prevent seeds from adhering to the drying air pipe (101) and causing blockage of the drying air pipe (101); Step 3: When drying the seeds, the temperature inside the mixing drying box (201) is detected by the temperature detection probe (114) inside the detection bracket (113) to avoid uneven drying of the seeds caused by excessive temperature. When the temperature is too high, a large amount of moisture on the surface of the seeds will be lost, but the moisture inside the seeds is difficult to evaporate, resulting in uneven evaporation of moisture on the surface and inside of the seeds, which may cause seed cracks and reduce the germination rate. When the seed drying temperature is low, the seed drying time is prolonged, thus reducing the seed drying efficiency. The mixing drying box (201) is heated evenly in a cycle through the heating wire (115) and the circulation fan (116) inside the heating box (112). The circulating air is evenly distributed inside the mixing drying box (201), thereby improving the uniformity and drying efficiency of seed drying. When it is necessary to cool the inside of the mixing drying box (201), the electric telescopic rod (119) is started. When the electric telescopic rod (119) contracts, it drives the opening and closing sliding disc (118) to slide inside the opening and closing bracket (117). When the opening and closing rotating rod (126) rotates, it can drive the opening and closing sliding sleeve (124) and the opening and closing baffle (127) to move relatively, opening the middle of the opening and closing sliding disc (118), so that the outside air enters the inside of the mixing drying box (201) through the second connecting pipe (120) and mixes with the drying hot air, and the temperature inside the mixing drying box (201) can be quickly reduced to the specified temperature, thereby improving the seed drying effect, ensuring the water content of the seeds, and increasing the germination rate of the seeds. While the hot air is circulating, the drying device (121) can be used to absorb the water vapor in the hot air, thereby improving the drying effect.
