Description

Technical Field

[0001] The invention relates to the technical field of seed processing, in particular to a seed drying device. Background Art

[0002] Seeds are key means of production in agricultural production, and their quality is directly related to the yield and quality of crops. Among them, the moisture content of seeds is one of the key factors affecting their quality. Excessive moisture content can easily cause seeds to mold and deteriorate, and reduce the germination rate. Therefore, the seeds need to be properly dried to ensure that their moisture content reaches the safe storage standard. Drying is an important link in ensuring seed quality.

[0003] At present, flat-bed drying devices are commonly used to dry seeds. The device is mainly composed of mesh belt conveyors, hot air systems and other components. During operation, wet seeds are loaded onto the horizontal mesh belt conveyor, and hot air penetrates the seed layer from bottom to top through the mesh belt pores of the mesh belt conveyor, so that the hot air dries the wet seeds. During this period, the mesh belt conveyor gradually transports the seeds from the feed end to the discharge end to complete the continuous drying of the seeds.

[0004] However, the above drying process has the following problems: 1. The seeds are not dried thoroughly: when the mesh belt conveyor is transporting seeds, the seeds are in a stationary state relative to the mesh belt conveyor, and the seeds are prone to uneven distribution, resulting in excessive accumulation of seeds in some areas. When the hot air penetrates the seed layer from bottom to top, the seeds on the upper side of the seed pile are prone to insufficient heating, which in turn affects the drying effect of the seeds and the drying consistency of the overall seeds.

[0005] 2. Clogging of mesh belt gaps: When seeds are poured onto the mesh belt conveyor, seeds with smaller particle sizes or impurities on the seeds may be embedded in the mesh belt gaps of the mesh belt conveyor, causing the mesh belt gaps of the mesh belt conveyor to be blocked, which will then reduce the amount of hot air entering and directly affect the drying efficiency of the seeds.

DETAILED DESCRIPTION

[0030] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0031] See Figure 1 and Figure 2 A seed drying device includes a flat-bed dryer 1. The flat-bed dryer 1 includes two side panels 11 arranged front and back. A mesh belt conveyor group 12 is commonly installed on the two side panels 11. A flipping unit 2 is installed on the opposite sides of the two side panels 11 and above the mesh belt conveyor group 12. A dredging unit 3 for dredging the mesh belt conveyor group 12 is also installed on the opposite sides of the two side panels 11.

[0032] It should be noted that the flat-bed dryer 1 in the present invention also includes a bottom plate and two frame plates arranged on the left and right. The frame plate, the bottom plate and the side panels 11 together constitute the dryer frame. The left frame plate is connected to the external hot air system. The right frame plate is provided with a discharge port. The mesh belt conveyor group 12 is located in the middle of the dryer frame. The hot air is introduced into the lower side of the dryer frame through the external hot air system. The hot air flows from bottom to top and penetrates the mesh belt pores of the mesh belt conveyor group 12 to dry the seeds on the mesh belt conveyor group 12. The mesh belt conveyor group 12 can convey the seeds to the right to the corresponding position of the discharge port, so that the dried seeds can be moved out of the dryer frame.

[0033] The present invention is used for continuously drying seeds, and the present invention can continuously turn over the seeds and spread the seeds evenly, preventing excessive local accumulation of seeds, allowing the seeds to be evenly heated, and thus ensuring the drying effect of the seeds. At the same time, the present invention can also clear the mesh belt pores of the mesh belt conveyor group 12, preventing the mesh belt pores of the mesh belt conveyor group 12 from being blocked, and ensuring the drying efficiency of the seeds.

[0034] Specifically, first, the wet seeds are continuously conveyed to the mesh belt conveyor group 12 through the external conveying equipment, and the mesh belt conveyor group 12 is started to continuously drive the wet seeds to move to the right, and the hot air is introduced into the lower side of the dryer frame through the external hot air system. The hot air flows from bottom to top and penetrates the mesh belt pores and seed layer of the mesh belt conveyor group 12 in turn to dry the wet seeds. When the mesh belt conveyor group 12 continues to drive the wet seeds to move to the right, the turning unit 2 and the dredging unit 3 are started at the same time. When the mesh belt conveyor group 12 drives the wet seeds to move to the turning unit 2, the turning unit 2 can turn the wet seeds, and the turning unit 2 can also flatten the wet seeds front and back, so that the seeds are evenly distributed on the mesh-belt conveyor group 12, so that the wet seeds can be evenly heated. At the same time, the dredging unit 3 continuously dredges the mesh belt pores of the mesh belt conveyor group 12 to prevent seeds or impurities with smaller particle sizes from being embedded in the mesh belt pores of the mesh belt conveyor group 12, thereby ensuring the amount of hot air entering. The mesh belt conveyor group 12 drives the seeds after drying to move out of the dryer frame from the discharge port of the dryer frame, thereby realizing continuous drying of the wet seeds.

[0035] See Figure 1 、 Figure 2 and Figure 3 The turning unit 2 includes a plurality of rotating shafts 21 evenly arranged left and right on opposite sides of the two side panels 11 through a rotating group 22, and a plurality of turning bucket groups evenly arranged front and back are arranged on the outside of the rotating shaft 21 through a material digging group 24. The turning bucket group includes a plurality of turning buckets 23 evenly arranged circumferentially, and a flattening group 25 for flattening seeds front and back is installed between the outside of the rotating shaft 21 and the two side panels 11.

[0036] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The rotating group 22 includes a sliding sleeve 221 that is slidably sleeved on the rotating shaft 21 in the front and rear directions, and the sliding sleeve 221 is rotatably connected to the corresponding side panel 11. A plurality of circumferentially evenly arranged return springs 222 are connected between the inner wall of the sliding sleeve 221 and the end surface of the rotating shaft 21. A driving member 223 is commonly installed between the plurality of sliding sleeves 221 located on the front side and the corresponding side panel 11.

[0037] It should be noted that the driving member 223 includes a pulley fixedly mounted on the front end of the sliding sleeve 221. The two adjacent pulleys on the left and right are connected by a belt. The pulley on the far right is connected to the motor output shaft fixedly mounted on the front side panel 11 through a belt. By starting the motor, all the pulleys are driven to rotate through the belt, so that the pulley drives the corresponding sliding sleeve 221 to rotate.

[0038] The turning unit 2 is used to turn the seeds and flatten the seeds front and back; specifically, the starting driving member 223 drives the multiple sliding sleeves 221 located on the front side to rotate clockwise, so that the sliding sleeves 221 drive the corresponding rotating shaft 21 to rotate continuously clockwise, and the rotating shaft 21 drives the corresponding sliding sleeve 221 located on the rear side to rotate clockwise, and the rotating shaft 21 drives the turning bucket 23 to rotate clockwise through the material digging group 24. When the turning bucket 23 contacts the mesh belt conveyor group 12 and continues to rotate, as the mesh belt conveyor group 12 drives the seeds to move to the right, the seeds on the mesh belt conveyor group 12 can move into the turning bucket 23, and the turning bucket 23 is turned clockwise. The material-dispensing group 24 corresponding to the bucket 23 can also dispense seeds into the flipping bucket 23, ensuring that there is a certain amount of seeds in the flipping bucket 23, so that the flipping bucket 23 drives the seeds inside it to rotate. When the flipping bucket 23 rotates to the highest point and continues to rotate, the seeds in the flipping bucket 23 move out of the flipping bucket 23 under the action of gravity and fall onto the mesh-belt conveyor group 12, thereby turning the seeds and preventing some seeds from being insufficiently heated. At the same time, the flattening group 25 can flatten the seeds on the mesh-belt conveyor group 12 front and back to prevent excessive accumulation of seeds in some areas, ensuring that the seeds can be evenly heated, and thus ensuring the drying effect of the seeds. It should be noted that Figure 2 、 Figure 3 and Figure 4 In the figure, the rotation direction of the corresponding structure is represented by a combination of curves and black arrows.

[0039] See Figure 1 、 Figure 3 、 Figure 4 and Figure 5 , a clearance groove is opened at the position corresponding to the flip bucket 23 on the outside of the rotating shaft 21, and the material digging group 24 includes a clearance plate 242 radially slidingly installed in the clearance groove through a top spring 241, and a connecting plate 243 is installed on the side of the clearance plate 242 away from the axis of the rotating shaft 21 for tangential sliding along the rotating shaft 21, and the end of the connecting plate 243 away from the clearance plate 242 is fixedly connected to the corresponding flip bucket 23; wherein, a rubber strip is installed at the end where the flip bucket 23 contacts the mesh belt conveyor group 12.

[0040] See Figure 4 and Figure 5 The front and rear inner walls of the give way groove are both provided with a corrugated groove 211 , and the front and rear ends of the connecting plate 243 are both fixedly mounted with a toggle rod 244 , and the toggle rod 244 is slidably mounted in the corresponding corrugated groove 211 .

[0041] See Figure 4 and Figure 5 The connecting plate 243 and the side with the same opening direction as the flip bucket 23 are hinged with a material-diverting plate 245 through a torsion spring shaft. The end of the material-diverting plate 245 away from the connecting plate 243 is set as an elastic telescopic structure. A plurality of through holes evenly arranged front and back are opened on the material-diverting plate 245. A stop plate 212 is fixedly installed at the position of the material-diverting plate 245 on the outside of the rotating shaft 21, and the side of the stop plate 212 away from the rotating shaft 21 is in contact with the side of the material-diverting plate 245 away from the corresponding flip bucket 23.

[0042] When the turning shaft 21 rotates clockwise, the turning shaft 21 drives the turning bucket 23 to rotate through the yield plate 242 and the connecting plate 243. When the turning bucket 23 contacts the mesh belt conveyor group 12, the turning bucket 23 has not yet rotated to the lowest position. Then, when the turning bucket 23 continues to rotate, the turning bucket 23 is blocked by the mesh belt conveyor group 12, and the turning bucket 23 drives the yield plate 242 to move radially toward the center of the turning shaft 21 through the connecting plate 243 and compresses the top extension spring 241. When the connecting plate 243 moves radially toward the center of the turning shaft 21, the connecting plate 243 drives the toggle rod 244 to move in the corrugated groove 211. At the same time, when the toggle rod 244 Under the cooperation of the corrugated structure of the corrugated groove 211, the toggle rod 244 drives the flipping bucket 23 to move back and forth tangentially along the rotating shaft 21 through the connecting plate 243, and under the action of the top spring 241, the flipping bucket 23 can always be in contact with the mesh belt conveyor group 12, so that the flipping bucket 23 moves back and forth left and right along the surface of the mesh belt conveyor group 12. Through the setting of the rubber strip, when seeds are stuck between the flipping bucket 23 and the mesh belt conveyor group 12, the flipping bucket 23 is prevented from rigidly squeezing the seeds, causing damage to the seeds. At the same time, as the flipping bucket 23 moves left and right along the surface of the mesh belt conveyor group 12, the seeds stuck between the flipping bucket 23 and the mesh belt conveyor group 12 can be moved out, thereby preventing the seeds from always being stuck between the flipping bucket 23 and the mesh belt conveyor group 12.

[0043] In addition, the rotating shaft 21 also drives the material-dipping plate 245 to rotate through the yield plate 242 and the connecting plate 243. When the flipping bucket 23 contacts the mesh belt conveyor group 12 and continues to rotate with the rotating shaft 21, the flipping bucket 23 drives the connecting plate 243 to move radially toward the center of the rotating shaft 21, and the connecting plate 243 drives the material-dipping plate 245 to move radially toward the center of the rotating shaft 21. Under the blocking action of the stop plate 212, the material-dipping plate 245 rotates toward the direction close to the flipping bucket 23 based on the hinged part with the connecting plate 243, and the elastic telescopic structure of the material-dipping plate 245 can always fit the mesh belt On the mesh-belt conveyor group 12, when the flipping bucket 23 rotates to the lowest point, the flipping bucket 23 drives the connecting plate 243 to move radially toward the center of the rotating shaft 21 to the extreme position. At this time, the material-diverting plate 245 rotates to the extreme position toward the flipping bucket 23 based on the hinge between it and the connecting plate 243. During this process, the material-diverting plate 245 shifts the seeds between it and the corresponding flipping bucket 23 into the flipping bucket 23, so that the flipping bucket 23 can always flip a certain amount of seeds, ensuring that all seeds on the mesh-belt conveyor group 12 can be picked up by the flipping bucket 23 to achieve flipping, further ensuring the drying effect of the seeds.

[0044] When the flipping bucket 23 rotates to the point where it begins to separate from the mesh-belt conveyor group 12, under the action of the top spring 241, the flipping bucket 23 moves radially back to its original position away from the center of the rotating shaft 21, and the material-diverting plate 245 rotates back to its original position away from the flipping bucket 23 under the torsional force of its torsion spring shaft. When the flipping bucket 23 rotates to the highest point and continues to rotate, the seeds in the flipping bucket 23 move out of the flipping bucket 23 under the action of gravity and fall onto the material-diverting plate 245. Most of the seeds pass through the through holes on the material-diverting plate 245 and fall evenly onto the mesh-belt conveyor group 12. A small number of seeds (seeds near the edge of the material-diverting plate 245) fall along the material-diverting plate 245 onto the mesh-belt conveyor group 12, thereby achieving uniform flipping of the seeds, which is beneficial to improving the uniformity of seed heating and ensuring the drying effect of the seeds.

[0045] See Figure 3 , multiple circumferentially evenly distributed matching rods 213 are fixedly installed on the front and rear sides of the rotating shaft 21, and multiple circumferentially evenly distributed arc-shaped matching blocks 111 are arranged on the opposite sides of the two side panels 11 and located on the outside of the rotating shaft 21. The multiple arc-shaped matching blocks 111 located on the outside of the front and rear ends of the same rotating shaft 21 are staggered in the circumference, and the arc-shaped matching blocks 111 are fixedly connected to the corresponding side panels 11 through L-shaped connecting frames 112. The side of the arc-shaped matching blocks 111 away from the corresponding side panels 11 is set to an inclined surface that matches the corresponding matching rod 213.

[0046] See Figure 1 and Figure 3The flattening group 25 includes two connecting sleeves 251 symmetrically arranged front and back that are rotatably sleeved on the outside of the rotating shaft 21. The upper side of the connecting sleeve 251 is fixedly connected to the corresponding side panel 11 through an L-shaped connecting support rod 252, and the connecting end of the connecting support rod 252 and the side panel 11 is set to a telescopic structure. Two symmetrically arranged oblique rods 253 are fixedly installed on the outside of the connecting sleeve 251. The two oblique rods 253 arranged front and back are tilted downward at one end away from the connecting sleeve 251 and are jointly fixed with a square plate 254. A plurality of spreading plates 255 evenly arranged front and back are fixedly installed on the lower end of the square plate 254, and the lower end of the spreading plate 255 is set to a comb-tooth structure.

[0047] The flattening group 25 is used to flatten the seeds forward and backward; specifically, when the rotating shaft 21 rotates, the rotating shaft 21 drives the matching rod 213 to rotate. When the matching rod 213 contacts the corresponding arc-shaped matching block 111 inclined surface and continues to rotate, the matching rod 213 drives the rotating shaft 21 to move away from the corresponding sliding sleeve 221 under the action of the corresponding arc-shaped matching block 111 inclined surface. When the matching rod 213 and the corresponding arc-shaped matching block 111 are separated, the rotating shaft 21 returns to its original position under the action of the rebound force of the return spring 222. Position, since multiple arc-shaped matching blocks 111 located on the outer sides of the front and rear ends of the same rotating shaft 21 are staggered in the circumferential direction, and there are multiple arc-shaped matching blocks 111, the rotating shaft 21 can move back and forth, that is, the rotating shaft 21 can drive the turning bucket 23 and the material-diverting plate 245 to move back and forth, so that the seeds can be evenly distributed in the turning bucket 23, and ensure that the seeds fall evenly through the through holes on the material-diverting plate 245 onto the mesh belt conveyor group 12, further ensuring that the seeds are evenly turned.

[0048] When the rotating shaft 21 moves back and forth, under the action of the connecting support rod 252, the rotating shaft 21 drives the square plate 254 to move back and forth through the connecting sleeve 251 and the inclined rod 253, and the square plate 254 drives the spreading plate 255 to move back and forth, so that the comb-like structure of the spreading plate 255 can spread the seeds on the mesh belt conveyor group 12 back and forth, preventing excessive local accumulation of seeds, ensuring that the seeds can be heated evenly, and thus ensuring the drying effect of the seeds.

[0049] See Figure 1 、 Figure 2 、 Figure 6 and Figure 7The dredging unit 3 includes a reciprocating plate 32 installed between the opposite sides of the two side panels 11 by sliding left and right through a reciprocating member 31. A plurality of evenly arranged top extension groups 33 are installed on the reciprocating plate 32. Hard bristles 34 are installed on the top extension group 33. The top extension group 33 is used to drive the hard bristles 34 to extend upward to dredge the mesh belt gap of the mesh belt conveyor group 12. A spreading group 35 for spreading seeds evenly is installed on the reciprocating plate 32. An extrusion group 36 for squeezing and dispersing agglomerated seeds is installed on the spreading group 35. A plurality of guide holes 321 evenly arranged left and right are opened on the reciprocating plate 32, and the upper ends of the guide holes 321 are arranged tilted to the left.

[0050] It should be noted that the reciprocating member 31 includes an active plate fixedly mounted on the front end of the reciprocating plate 32. The front end of the active plate slides left and right through the side panel 11 located on the front side, and the active plate is mounted on the threaded rod by threaded fitting. The left end of the threaded rod is fixedly connected to the output shaft of the reciprocating motor fixedly mounted on the front side panel 11, and the right end of the threaded rod is rotatably connected to the fixed plate fixedly mounted on the front side panel 11. By starting the reciprocating motor to drive the threaded rod to rotate back and forth, the threaded rod drives the reciprocating plate 32 to move back and forth left and right through the active plate.

[0051] The dredging unit 3 is used to dredge the mesh belt pores of the mesh belt conveyor group 12; specifically, when hot air is introduced into the lower side of the dryer frame through the external hot air system, the hot air flows from bottom to top through the guide holes 321 and then penetrates the mesh belt pores of the mesh belt conveyor group 12, and under the action of the inclined structure of the guide holes 321, the hot air can form convection with the seeds moving to the right, further ensuring uniform drying of the seeds and improving the drying efficiency of the seeds. At the same time, the reciprocating member 31 is started to drive the reciprocating plate 32 to move back and forth left and right, so that the reciprocating plate 32 drives the hard brush bristles 34 to move back and forth left and right through the top extension group 33, and then when the particle size is When smaller seeds or impurities are embedded in the mesh belt pores of the mesh belt conveyor group 12, the hard bristles 34 can clean the mesh belt pores of the mesh belt conveyor group 12 to ensure the intake of hot air, thereby ensuring the drying efficiency of the seeds. At the same time, the extension group 33 can drive the hard bristles 34 to extend upward so that the hard bristles 34 can be inserted into the mesh belt pores of the mesh belt conveyor group 12, ensuring that the mesh belt pores of the mesh belt conveyor group 12 are thoroughly cleaned, and the reciprocating plate 32 also drives the spreading group 35 to spread the seeds left and right, further ensuring that the seeds are evenly distributed on the mesh belt conveyor group 12, thereby further ensuring that the seeds are evenly dried.

[0052] See Figure 6 and Figure 7The extension group 33 includes an extension plate 332 that is mounted on the reciprocating plate 32 for sliding up and down through a plurality of connecting springs 331. The extension plate 332 is connected to its corresponding hard bristles 34. Lifting rods 333 are fixedly mounted on both ends of the extension plate 332. Two symmetrically arranged lifting plates 113 are fixedly mounted on the opposite sides of the two side panels 11 and at positions corresponding to the lifting rods 333. The sides of the symmetrical lifting plates 113 that are close to each other are both set to inclined surfaces that cooperate with the lifting rods 333.

[0053] The extension group 33 is used to drive the hard bristles 34 to extend upward; specifically, Figure 7 As shown, the inclined surface on the lifting rod 333 is inclined downward near the side of the end of the lifting rod 333. When the reciprocating plate 32 moves back and forth left and right, the reciprocating plate 32 drives the extending plate 332 to move back and forth left and right. When the extending plate 332 drives the lifting rod 333 to move until it contacts the corresponding inclined surface of the lifting plate 113 and continues to move, the lifting rod 333 drives the extending plate 332 to move upward under the action of the inclined surface of the lifting plate 113 and compresses the connecting spring 331. The extending plate 332 drives its corresponding hard bristles 34 to extend upward. When the reciprocating plate 32 drives the extending plate 332 to move to the initial position, the extending plate 332 moves downward to the initial position under the action of the rebound force of the connecting spring 331.

[0054] See Figure 2 、 Figure 6 and Figure 8 The leveling group 35 includes a plurality of leveling plates 351 distributed on opposite sides of the two side panels 11 and located above the mesh belt conveyor group 12, and the leveling plates 351 and the rotating shaft 21 are arranged at intervals on the left and right. The front and rear ends of the leveling plates 351 are fixedly connected to the reciprocating plate 32 through the lower end surface of the vertical section of the L-shaped transmission rod 352, and the L-shaped transmission rod 352 and the corresponding side panel 11 are slidably connected on the left and right, and the lower end of the leveling plate 351 is set to a comb-tooth structure.

[0055] See Figure 2 、 Figure 6 and Figure 8 The extrusion group 36 includes a triangular extrusion rod 361 distributed in the comb hole of the smoothing plate 351, and a connecting rod 362 is fixedly installed on the upper end of the extrusion rod 361. A lower pressure rod 363 is fixedly installed on the upper ends of multiple connecting rods 362. The connecting rod 362 and the lower pressure rod 363 are both connected to the corresponding smoothing plate 351 for sliding up and down. The front and rear ends of the lower pressure rod 363 slide up and down through the smoothing plate 351. An inverted V-shaped guide groove 114 is provided on the opposite sides of the two side panels 11 and corresponding to the lower pressure rod 363, and the front and rear ends of the lower pressure rod 363 are both connected to the corresponding guide groove 114 for sliding.

[0056] The spreading group 35 is used to spread the seeds evenly left and right; specifically, when the reciprocating plate 32 moves back and forth left and right, the reciprocating plate 32 drives the corresponding spreading plate 351 to move back and forth left and right through the L-shaped transmission rod 352, so that the comb-tooth structure of the spreading plate 351 spreads the seeds on the mesh belt conveyor group 12 evenly left and right, and at the same time, the spreading plate 351 drives the squeezing rod 361 to move back and forth left and right through the connecting rod 362 and the lower pressure rod 363. Under the cooperation of the lower pressure rod 363 and one of the inclined sections of the guide groove 114, the lower pressure rod 363 drives the corresponding squeezing rod 361 to move downward through the connecting rod 362. When the seeds on the squeezed mesh belt conveyor group 12 are agglomerated, the agglomerated seeds can be dispersed under the squeezing action of the squeezing rod 361, further ensuring that the seeds can be dried evenly, thereby ensuring the drying effect of the seeds.
