Description

Technical Field

[0001] The present invention relates to the technical field of grain storage, and in particular to a grain drying device and method for grain storage. Background Art

[0002] After the grain is harvested, it often still contains a lot of moisture. Excessive moisture content in the grain can cause problems such as grain deterioration, mildew, and rot. It is also easy to breed pests and mold, so it is necessary to reduce its moisture content by drying it in the sun and in the air; to improve the storage durability of the grain, extend its shelf life, and prevent the grain from deteriorating; in addition, the grain may absorb moisture in the air during storage, so it needs to be dried again.

[0003] Currently, grains are usually spread on the ground for drying. During this period, the grains will produce a large amount of water vapor under the sunlight. A small amount of water vapor will condense on the ground to form water droplets, resulting in a slower drying speed of the grains.

[0004] In the prior art, a large number of grain drying devices for grain storage are also disclosed. Among them, for example, a Chinese patent with publication number CN215412868U discloses a grain drying device for grain storage; it includes a fixed rod, a drying rack and a rain shield mechanism, the rain shield mechanism has a support column, an electric telescopic rod, a signal receiver and a humidity sensor. When in use, when it rains or the weather changes suddenly, the humidity sensor will detect the increase in humidity in the air, thereby sending an electrical signal to the controller. After receiving the signal, the controller sends a control command to the signal receiver to control the electric telescopic rod to extend, and the drying rack is blocked to prevent rain from wetting the grain and making the grain inedible. When drying, the solar panel will absorb solar energy, convert it into electrical energy and store it in the battery. The battery is used to power the heating tube, and the heating tube is started when drying the grain to heat and dry the grain, and further evaporate the moisture inside the grain.

[0005] However, in the process of drying grain for grain storage using the above-mentioned prior art, there are still the following shortcomings: 1. Although the above-mentioned prior art can send an electrical signal to the controller through the humidity sensor when it rains or the weather changes suddenly, and control the electric telescopic rod to extend to cover the drying rack to prevent rain from wetting the grain, the grain cannot be recovered. When it rains and is windy, it is impossible to completely prevent rain from wetting the grain by simply covering it. The rain may fall down tiltedly under the influence of wind, thereby wetting the grain.

[0006] 2. Although the above-mentioned prior art can dry grains through drying racks and drying boards, during the drying process, the grains will produce a large amount of water vapor under the sunlight, and a small amount of water vapor will condense on the drying boards to form water droplets, resulting in a slower drying speed of the grains. However, the bottom of the drying boards used in the above-mentioned prior art does not have through holes for grain ventilation. Therefore, the water vapor condensed on the bottom wall of the drying boards during the grain drying process will cause the grain drying speed to slow down, and the grains will be easily germinated if they are immersed in the condensed water vapor for a long time, affecting their consumption and subsequent processing.

[0007] 3. Although the above device can heat and dry the grain through the heating tube, it is possible that the grain close to the heating tube can be dehydrated quickly, but the grain far away from the heating tube needs to be air-dried for a long time. During the drying process, the grain cannot be turned over, so that the uneven heating makes it easy for the grain far away from the heating tube to be in a moist state for a long time, which may cause it to mold and become inedible.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the grain drying methods of the prior art. Summary of the invention

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The present invention pushes a plurality of drying holes to rotate toward a side away from the partition through an opening and closing frame. The sealing mesh plate rotates synchronously under the push of the drying holes. The air holes between the sealing mesh plate and the drying holes gradually overlap during the rotation. When the drying holes and the sealing mesh plate rotate to a horizontal state, the rotation stops. The drying net and the blocking net are gradually opened to be in the same horizontal plane as the drying holes under the pull of two adjacent drying holes. At this time, the air holes between the sealing plate and the drying holes overlap, thereby achieving air circulation at the bottom of the grain during the grain drying process. The water vapor generated during the grain drying will not form water droplets at the bottom, thereby affecting the drying of the grain, thereby improving the grain drying speed.

[0023] 2. The present invention pulls the drying hole plate to rotate toward the side close to the partition through the opening and closing frame, and the drying hole plate pulls the sealing mesh plate to rotate synchronously through the pull rod. During the rotation, the air holes between the sealing mesh plate and the drying hole plate are gradually staggered. During the rotation of the drying net, the grains gradually gather toward the middle along the inclined surface of the drying net. When the drying hole plate and the sealing mesh plate are rotated to a vertical state, the side edges of the drying hole plate fit together, the air holes between the sealing mesh plate and the drying hole plate are completely staggered, and the sealing mesh plate and the drying hole plate are sealed. The triangular plates fit together to form a seal, thereby preventing rain from wetting the grain. Even in windy conditions, the grains cannot be wetted by rain because they are shielded by the drying hole plates and the sealing mesh plates on all sides.

[0024] 3. The present invention drives the spreading plate to rotate around the screw rod through the spreading curved plate. When the spreading curved plate pushes the grain from the partition to the drying hole plate and the drying net, the spreading plate flattens the grain on the drying hole plate and the drying net through the paddles at the bottom, and spreads all the grains to the same thickness. After the driving motor reduces the rotation speed, the paddles at the bottom of the two spreading plates are inclined at relative angles. After the paddles at the bottom of the spreading plate on one side push the grain, the spreading plate on the other side will push the grain again when it rotates to the same position, thereby realizing the continuous turning of the grain during the grain drying process, so that the grain is heated more evenly during the drying process, and the drying and air-drying efficiency of the grain is greatly accelerated.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-Figure 10 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0038] The embodiment of the present application discloses a grain drying device for grain storage, which is explained as follows: the grain drying device for grain storage is mainly used in the process of drying grain for grain storage, and in terms of technical effect, it can allow air to circulate at the bottom of the grain during the grain drying process, and the water vapor generated during the grain drying will not form water droplets at the bottom, thereby affecting the drying of the grain, thereby improving the speed of grain drying, especially by constantly turning the grain over during the grain drying process, so that the grain is heated more evenly during the drying process, greatly accelerating the drying and air-drying efficiency of the grain. Furthermore, the grain drying device for grain storage can also adjust the height of the drying hole plate according to the different drying thicknesses required according to the type of grain, thereby achieving the spreading of different thicknesses of different types of grain.

[0039] Embodiment 1:

[0040] Reference Figure 1 and Figure 2 As shown, a grain drying device for grain storage includes a base 1, a partition 2 is installed on the upper end of the base 1, a driving motor 3 is connected to the bottom of the partition 2, a plurality of drying hole plates 4 are hinged on the side of the partition 2, an opening and closing frame 5 is installed on the top of the partition 2, a humidity detector 7 is installed on the drying hole plate 4, the opening and closing frame 5 is sleeved on the outer wall of the output shaft of the driving motor 3, and the opening and closing frame 5 is connected to the drying hole plate 4.

[0041] In the specific implementation process, the grain is stored in a closed space composed of a plurality of drying holes 4. When the humidity detector 7 detects that the humidity in the grain is high, it automatically controls the driving motor 3 to rotate, thereby driving the opening and closing frame 5 to push the drying holes 4 to open and dry the grain. After the drying holes 4 are fully opened, the opening and closing frame 5 can also automatically spread the piled grain to prevent the piled grain from being unevenly heated during the drying process, resulting in only the surface of the grain being dried while the internal grain is still damp. During the drying, if it rains, the humidity detector 7 detects that the humidity in the air is high, and the driving motor 3 reverses to drive the opening and closing frame 5 to pull the drying holes 4 to reset, forming a closed state, thereby preventing the grain from becoming damp due to rain and becoming moldy during subsequent storage.

[0042] Reference Figure 2As shown, a large amount of water vapor will be generated during the grain drying process, and a small amount of water vapor will condense at the bottom of the grain to form water droplets, thereby affecting the drying of the grain and increasing the drying time. Based on this, in this embodiment, the drying hole plate 4 is further improved; specifically, a triangular baffle 41 is installed on the side of the upper end of the drying hole plate 4 away from the partition 2, and the drying hole plates 4 are equidistantly distributed along the circumferential direction of the side edge of the partition 2, and the sides of two adjacent drying hole plates 4 are commonly connected with a retractable drying net 42 A plurality of sealing mesh panels 43 equidistantly distributed along the circumference are hinged on the side of the base 1, a blocking mesh 44 is connected to the upper end of the drying net 42 away from the partition 2, and both sides of the blocking mesh 44 are connected to the adjacent triangular baffles 41, the sealing mesh panel 43 is fitted with the drying hole plate 4, and the sealing mesh panel 43 and the drying hole plate 4 are provided with a plurality of equidistantly arranged air holes 45, and a pull rod 46 is hinged together at one end of the sealing mesh panel 43 away from the partition 2 and at the top of the drying hole plate 4 away from the partition 2.

[0043] In the initial state, the drying holes 4 are attached to each other to form a closed state, the sealing mesh plate 43 is staggered with the air holes 45 on the drying holes 4, and the drying net 42 is located in the drying holes 4, so that the sealing mesh plate 43 cooperates with the drying holes 4 to form a closed state in the internal space. Figure 3 shown.

[0044] When the drying hole plate 4 and the sealing mesh plate 43 are rotated to a horizontal state, they stop rotating. The drying net 42 and the blocking net 44 are gradually opened to be in the same horizontal plane with the drying hole plate 4 under the pull of the two adjacent drying hole plates 4. At this time, the air holes 45 between the sealing plate and the drying hole plate 4 overlap, so that air circulation is achieved at the bottom of the grain during the grain drying process. The water vapor generated during the grain drying will not form water droplets at the bottom, thereby affecting the drying of the grain and improving the drying speed of the grain. Subsequently, the opening and closing frame 5 spreads the grain under the drive of the driving motor 3, and prevents the grain from falling to the ground from the drying hole plate 4 during the spreading process through the blocking net 44 and the triangular baffle plate 41.

[0045] When it rains, the opening and closing frame 5 pulls the drying plate 4 to rotate toward the side close to the partition 2, and the drying plate 4 pulls the sealing mesh plate 43 to rotate synchronously through the pull rod 46. During the rotation, the air holes 45 between the sealing mesh plate 43 and the drying plate 4 are gradually staggered, and the drying net 42 shrinks between the two adjacent drying plates 4 and enters the drying plate 4. During the rotation of the drying plate 4, the grain gradually gathers toward the middle along the inclined surface of the drying plate 4. When the drying plate 4 and the sealing mesh plate 43 are rotated to a vertical state, the sides of the drying plate 4 fit together, and the air holes 45 between the sealing mesh plate 43 and the drying plate 4 are completely staggered, and the sealing mesh plate 43 and the drying plate 4 are sealed. The triangle plates fit together to form a seal, thereby preventing rain from wetting the grain. Even in the case of wind, rain cannot wet the grain due to the shelter of the drying plate 4 and the sealing mesh plate 43 on all sides.

[0046] Reference Figure 4 and Figure 5 As shown, in order to automatically and evenly spread and recycle the grain during the drying process, so as to avoid manual spreading and recycling, the opening and closing frame 5 is further improved in this embodiment; specifically, the opening and closing frame 5 includes a lower ring 51 installed on the upper end of the partition 2, and the output shaft of the driving motor 3 passes through the partition 2 and the lower ring 51 and is connected to a screw 53, a blocking block 54 is installed on the top of the screw 53, and the side wall of the screw 53 is sleeved with an upper ring 55 connected by threads, and the side wall of the lower ring 51 is opened near the top side with a plurality of circumferentially distributed screws. A first opening groove 56 is formed, and a plurality of second opening grooves 57 corresponding to the positions of the first opening grooves 56 are formed on the side of the upper end of the upper ring 55; a rocker 58 and a transmission rod 59 are hinged in the first opening groove 56 and the second opening groove 57, respectively. The end of the rocker 58 away from the partition 2 is hinged to the bottom of the transmission rod 59 closest to it, and the end of the transmission rod 59 away from the partition 2 is hinged to a folding rod 61 through a hinge plate 60. The bottom of one side of the rocker 58 away from the partition 2 is hinged to the end of the hinge plate 60 away from the folding rod 61, and the end of the folding rod 61 away from the transmission rod 59 is hinged to the triangular plate.

[0047] Furthermore, in the present embodiment, a square groove 551 is provided in the middle of the upper ring 55, and a plurality of return springs 552 are symmetrically installed on the two inner side walls of the square groove 551 along the length direction, and the opposite sides of the plurality of return springs 552 on both sides are respectively connected with threaded plates 553 matching with the screw rod 53, and the two threaded plates 553 are located between the plurality of return springs 552 on the opposite sides and are connected with linkage blocks 554, and the bottom of the square groove 551 is located below the two linkage blocks 554 and is provided with through holes 555, and an extrusion block 556 matching with the linkage block 554 is installed at the top of the lower ring 51.

[0048] During the specific implementation process, when the grain is dried, the driving motor 3 drives the screw 53 to rotate. The threaded plate 553 is always in contact with the outer surface of the screw 53 under the pressure of the reset spring 552. The upper ring 55 cannot rotate because the lower ring 51 is fixedly connected to the top of the partition 2. The threaded plate 553 drives the upper ring 55 to move downward synchronously in cooperation with the thread of the screw 53. During the downward movement of the upper ring 55, the transmission rod 59 and the non-hinged end of the rocker 58 gradually approach each other, and the hinge rotates. The transmission rod 59 gradually turns from a downward tendency to a horizontal direction, and the rocker 58 gradually rotates to the side away from the screw 53 under the pull of the transmission rod 59.

[0049] During this process, the hinged plate 60 and the folding rod 61 rotate synchronously with the transmission rod 59. The rocker 58 applies a pulling force to the hinged plate 60 during the rotation process, and the hinged joint of the hinged plate 60 and the transmission rod 59 rotates. The hinged plate 60 drives the folding rod 61 to gradually rotate away from the screw rod 53, and the folding rod 61 drives the drying hole plate 4 to move synchronously away from the screw rod 53. At the same time, during the movement process, the hinged joint of the folding rod 61 and the drying hole plate 4 rotates; when the upper ring 55 moves to the top of the lower ring 51, the extrusion block 556 enters the through hole 555, and the linkage block 554 is squeezed by the extrusion block 556 during the continuous downward movement, driving the threaded plate 553 to move away from the screw rod 53, the reset spring 552 is adaptively retracted, and the threaded plate 553 loses thread cooperation with the screw 53. At this time, the upper ring 55 stops rotating, and the screw 53 continues to rotate, thereby realizing the opening of the drying hole plate 4, which is convenient for the subsequent spreading and drying of the grain.

[0050] When it rains, the driving motor 3 drives the screw 53 to reverse, and the threaded plate 553 drives the upper ring 55 to move upward synchronously in cooperation with the thread of the screw 53. While the upper ring 55 moves upward, the transmission rod 59 and the rocker 58 are gradually separated from the unhinged part, and the hinge rotates. The transmission rod 59 drives the hinge plate 60 and the folding rod 61 to move synchronously. The rocker 58 applies a thrust to the hinge plate 60 during the rotation. The hinge plate 60 rotates at the junction with the transmission rod 59 and drives the folding rod 61 to rotate synchronously. The folding rod 61 pulls the drying hole plate 4 to rotate toward the side close to the screw 53, and the grain gradually gathers along the inclined drying hole plate 4 until the drying hole plate 4 is closed. At this time, the motor stops rotating, thereby realizing automatic recovery and storage of grain to prevent the grain from becoming moldy and inedible due to moisture.

[0051] Reference Figure 2 and Figure 6As shown, during the process of spreading the grain, if the grain is piled up, the water vapor generated by the grain during drying cannot be well dispersed, thereby forming water droplets in the center, causing the surface of the grain to dry while the internal grain still has a high humidity. Based on this, a spreading mechanism is provided in the present embodiment; specifically, a receiving groove 511 is provided at the bottom of the lower ring 51, and a transmission gear 512 located in the receiving groove 511 is sleeved on the outer wall of the output shaft of the driving motor 3. A through groove 513 for connecting the receiving groove 511 with the outside is provided on the side wall of the lower ring 51 near the bottom. A connecting gear 514 located in the through groove 513 is rotatably connected to the top of the partition 2. A gear ring 515 meshing with the connecting gear 514 is connected to the top of the partition 2, and a plurality of circumferentially equidistantly distributed spreading curved plates 516 are connected to the outer wall of the gear ring 515.

[0052] In the specific implementation process, after the drying hole plate 4 is unfolded to be completely horizontal, the output shaft of the driving motor 3 drives the transmission gear 512 to rotate, the transmission gear 512 drives the connecting gear 514 to rotate, and the connecting gear 514 drives the gear ring 515 and the spreading curved plate 516 to rotate. At the beginning, due to the large amount of grain piled on the top of the partition 2, the driving motor 3 rotates at a faster speed. When the grain is gradually spread to the upper end of the drying net 42 by the spreading curved plate 516, the driving motor 3 turns to slow rotation, thereby realizing the spreading of the grain and preventing the accumulation of grain from causing a slow drying speed.

[0053] Reference Figure 5 and Figure 6 As shown, during the process of drying grain, the grain is easy to enter the lower ring 51, which may cause the gears to get stuck, thereby causing damage to the device. Based on this, a protective cover 518 is provided in this embodiment; specifically, a bottom ring 517 is installed on the upper end of the gear ring 515, and a protective cover 518 is installed on the top of the lower ring 51. The protective cover 518 is rotatably connected to the bottom ring 517, and sliding grooves 519 for the rocker 58 to slide are opened on the side and top of the protective cover 518, and sealing strips 520 are connected on both sides of the sliding groove 519.

[0054] In the specific implementation process, when the grain is dried or recovered and stored, the grain is always isolated outside the protective cover 518, and the bottom ring 517 rotates synchronously with the rotation of the gear ring 515. The protective cover 518 does not rotate synchronously with the bottom ring 517. When the rocker 58 slides in the sliding groove 519, the first sealing strip 520 is always in contact with the surface of the rocker 58, and the two first sealing strips 520 in the same sliding groove 519 are always in contact, thereby preventing the grain from entering the lower ring 51 during the drying process and causing the gear to get stuck, thereby preventing damage to the device.

[0055] Reference Figure 1 and Figure 7As shown, in order to prevent the grain from getting wet when it rains during the drying process, causing the grain to become moldy and inedible, and in order to prevent the grain from absorbing moisture in the air and becoming moist when the humidity in the air is high during storage and causing mold, a humidity detector 7 is provided in this embodiment; specifically, the humidity detector 7 is connected to the middle of the top of the drying hole plate 4, and a controller 71 is installed on the outer side of the base 1 close to the humidity detector 7, the humidity detector 7 and the controller 71 are electrically connected, and the controller 71 is electrically connected to the drive motor 3.

[0056] It should be noted that the controller 71 used in this embodiment is a PLC controller 71 in the prior art, which is mainly used to control the start and stop of the humidity detector 7 and the drive motor 3, which will not be repeated here; in addition, the humidity detector 7 involved in this embodiment is an existing technology for detecting the ambient humidity, which will not be repeated here.

[0057] In the specific implementation process, when the newly recovered grain is stored in the enclosed space formed between the drying holes 4, the humidity detector 7 detects that the humidity in the grain is high, and the humidity detector 7 transmits an electrical signal to the controller 71. The controller 71 controls the drive motor 3 to rotate, so as to spread the grain and dry it to prevent the grain from becoming moldy due to humid air during storage; when it rains during the grain drying process, the humidity detector 7 detects that the humidity in the air is high, and the humidity detector 7 transmits an electrical signal to the controller. The controller 71 controls the drive motor 3 to reverse, and the drive motor 3 drives the opening and closing frame 5 to control the drying holes 4 to recycle the grain to prevent the grain from being wetted by rain and becoming inedible.

[0058] Embodiment 2:

[0059] Reference Figure 8 and Fig. 9 As shown, on the basis of Example 1, during the process of spreading and drying, turning the grain over can better heat the grain, so that the grain can be dried more evenly. Based on this, in this embodiment, two of the relative spreading curved plates 516 are hinged with spreading plates 521, and the bottom of the two spreading plates 521 are equipped with multiple paddles 522 arranged along the length thereof, and the paddles 522 at the bottom of the two spreading plates 521 are relatively inclined.

[0060] It should be noted that, while the folding rod 61 drives the drying hole plate 4 to rotate, the paving plate 521 is driven by the drying hole plate 4 and rotates synchronously with the paving curved plate 516 at the hinge.

[0061] During the specific implementation process, the spreading plate 516 drives the spreading plate 521 to rotate around the screw 53. When the spreading plate 516 pushes the grain from the partition 2 to the drying hole plate 4 and the drying net 42, the spreading plate 521 flattens the grain on the drying hole plate 4 and the drying net 42 through the paddle 522 at the bottom, and spreads all the grain to the same thickness; when the driving motor 3 reduces the rotation speed, the paddles 522 at the bottom of the two spreading plates 521 are relative to each other due to their relative inclination angles. After the paddle 522 at the bottom of the spreading plate 521 on one side pushes the grain, the spreading plate 521 on the other side will push the grain again when it rotates to the same position, thereby realizing the continuous turning of the grain during the grain drying process, so that the grain is heated more evenly during the drying process, greatly accelerating the drying and air-drying efficiency of the grain.

[0062] Embodiment three:

[0063] Reference Figure 6 and Fig.10 As shown, on the basis of Example 2, in the process of spreading grain, in order to address the different thicknesses of grain required for drying, in this embodiment, a plurality of rotating grooves 81 are provided on the outer wall of the lower sleeve ring 51 from top to bottom, and linkage grooves 82 are symmetrically provided between the plurality of rotating grooves 81 along the lower sleeve ring 51, and spring grooves 83 are provided on the side walls of the linkage grooves 82, and a pressure spring 84 is installed on the side of the spring groove 83 away from the linkage groove 82, and the pressure spring 84 is connected to a semicircular protrusion 85 located in the spring groove 83, and the pressure spring 84 always applies a force to the semicircular protrusion 85 toward the side of the linkage groove 82, so that the semicircular protrusion 85 is in contact with the side of the linkage groove 82 in the initial state, and two L-shaped blocks 86 are symmetrically installed on the top of the gear ring 515, and the opposite sides of the two L-shaped blocks 86 are connected to a sliding rod 87 located in the bottommost rotating groove 81 through the bottom ring 517, and the second sealing strip 88 is connected to both sides of the L-shaped rod passed through the bottom ring 517.

[0064] In the specific implementation process, during the process of drying grains, the height of the drying hole plate 4 can be adjusted according to the different drying thicknesses required according to the type of grain, by rotating the sliding rod 87 and the L-shaped rod to below the semicircular protrusion 85, and then pulling the L-shaped rod upward, the L-shaped rod drives the sliding rod 87 to move upward, and the sliding rod 87 squeezes the semicircular protrusion 85, and the semicircular protrusion 85 slides into the spring groove 83, the pressure spring 84 adaptively contracts, and the sliding rod 87 enters the rotating groove 81 at the upper end, and then the protrusion is reset under the elastic force of the pressure spring 84, and the L-shaped rod drives the gear ring 515, the paving curved plate 516 and the paving plate 521 to rise synchronously, and then the drive motor 3 is started, the gear ring 515 drives the L-shaped rod and the sliding rod 87 to rotate synchronously, and the sliding rod 87 rotates circumferentially in the corresponding rotating groove 81, thereby realizing the paving of different thicknesses for different types of grains.

[0065] In addition, the present invention also provides a grain drying method for grain storage, comprising the following steps: S1, storing grain: when the newly recovered grain is stored in the enclosed space formed between the drying hole plates 4, the humidity detector 7 detects that the humidity in the grain is high, the humidity detector 7 will transmit an electrical signal to the controller 71, and the controller 71 controls the drive motor 3 to rotate.

[0066] S2. Adjusting the spreading thickness: the height of the drying hole plate 4 can be adjusted according to the required drying thickness of the grain type, by rotating the sliding rod 87 and the L-shaped rod to below the semicircular protrusion 85, and then pulling the L-shaped rod upwards. The L-shaped rod drives the sliding rod 87 to move upwards, and the sliding rod 87 squeezes the semicircular protrusion 85. The semicircular protrusion 85 slides into the spring groove 83, and the pressure spring 84 shrinks adaptively. The sliding rod 87 enters the rotating groove 81 at the upper end, and then the protrusion resets under the elastic force of the pressure spring 84, and the L-shaped rod drives the gear ring 515, the spreading curved plate 516 and the spreading plate 521 to rise synchronously, thereby achieving paving of different thicknesses for different types of grains.

[0067] S3, paving and drying: the driving motor 3 drives the screw 53 to rotate. The threaded plate 553 is always in contact with the outer surface of the screw 53 under the pressure of the return spring 552. The upper ring 55 cannot rotate because the lower ring 51 is fixedly connected to the top of the partition 2. The threaded plate 553 drives the upper ring 55 to move downward synchronously under the cooperation with the thread of the screw 53. During the downward movement of the upper ring 55, the transmission rod 59 and the unhinged end of the rocker 58 gradually approach each other, and the hinge rotates. The transmission rod 59 gradually turns from a downward inclination to a horizontal position. The rocker arm 58 is pulled by the transmission rod 59 and gradually rotates toward the side away from the screw rod 53. During this process, the hinged plate 60 and the folding rod 61 rotate synchronously with the transmission rod 59. The rocker arm 58 applies a pulling force to the hinged plate 60 during the rotation, and causes the hinged plate 60 and the transmission rod 59 to rotate at the hinge. The hinged plate 60 drives the folding rod 61 to gradually rotate toward the side away from the screw rod 53. The folding rod 61 drives the drying hole plate 4 to move synchronously toward the side away from the screw rod 53. At the same time, during the movement, the folding rod 61 rotates at the hinge with the drying hole plate 4.

[0068] When the air holes 45 between the sealing mesh plate 43 and the air holes 45 of the air holes 45 are gradually overlapped during the rotation, the upper ring 55 moves to the top of the lower ring 51, and the extrusion block 556 enters the through hole 555. The linkage block 554 is squeezed by the extrusion block 556 during the continuous downward movement, and the threaded plate 553 is moved to the side away from the screw rod 53. The reset spring 552 is adaptively extended and retracted, and the threaded plate 553 loses thread fit with the screw rod 53. At this time, the upper ring 55 stops rotating, and the screw rod 53 continues to rotate. When the air holes 4 and the sealing mesh plate 43 rotate to a horizontal state, they stop rotating. The air holes 45 between the sealing plate and the air holes 45 of the air holes 45 are gradually opened by the pull of the two adjacent air holes 4 to the same horizontal plane as the air holes 4. At this time, the air holes 45 between the sealing plate and the air holes 4 are overlapped.

[0069] The spreading plate 516 drives the spreading plate 521 to rotate around the screw 53. When the spreading plate 516 pushes the grain from the partition 2 to the drying hole plate 4 and the drying net 42, the spreading plate 521 flattens the grain on the drying hole plate 4 and the drying net 42 through the paddle 522 at the bottom, and spreads all the grains to the same thickness. When the driving motor 3 reduces the rotation speed, the paddles 522 at the bottom of the two spreading plates 521 are relative to each other due to their relative inclination angles. When the paddle 522 at the bottom of the spreading plate 521 on one side pushes the grain, the spreading plate 521 on the other side will push the grain again when it rotates to the same position, thereby realizing the continuous turning of the grain during the grain drying process.

[0070] S4. Returning grain when it rains: When it rains during the grain drying process, the humidity detector 7 detects that the humidity in the air is high, and the humidity detector 7 sends an electrical signal to the control. The controller 71 controls the drive motor 3 to drive the screw 53 to reverse, and the threaded plate 553 drives the upper ring 55 to move upward synchronously in cooperation with the thread of the screw 53. While the upper ring 55 moves upward, the transmission rod 59 and the rocker arm 58 are gradually separated from the unhinged part, and the hinge rotates. The transmission rod 59 drives the hinge plate 60 and the folding rod 61 to move synchronously. The rocker arm 58 applies a thrust to the hinge plate 60 during the rotation. The hinge plate 60 rotates at the junction with the transmission rod 59, and drives the folding rod 61 to rotate synchronously. The folding rod 61 pulls the drying hole plate 4 to rotate toward the side close to the screw 53, and the drying hole plate 4 pulls the sealing mesh plate 43 to rotate synchronously through the pull rod 46.

[0071] During the rotation, the air holes 45 between the sealing mesh plate 43 and the drying hole plate 4 are gradually staggered, and the drying net 42 shrinks between two adjacent drying hole plates 4 and enters the drying hole plates 4. During the rotation of the drying hole plates 4, the grains gradually gather toward the middle along the inclined surfaces of the drying hole plates 4. When the drying hole plates 4 and the sealing mesh plate 43 are rotated to a vertical state, the sides of the drying hole plates 4 fit together, and the air holes 45 between the sealing mesh plate 43 and the drying hole plates 4 are completely staggered, forming a seal between the sealing mesh plate 43 and the drying hole plates 4, and the triangular plates fit together to form a seal, thereby preventing rain from wetting the grain, thereby realizing automatic grain recovery and storage, and preventing the grain from becoming moldy and inedible due to moisture.
