Description

Technical Field

[0001] This invention relates to the field of grain drying, and more particularly to a structure for loosening grain and a grain dryer. Background Technology

[0002] A grain dryer is a hot air drying box that uses a rotary heating device to generate a large amount of hot air in a short time. It can kill insect eggs through high-temperature treatment and completely solve the problem of grain drying.

[0003] In existing grain dryers, the grain is first transported into the heating chamber, which is between the outer and inner heating chambers of the dryer. Then, hot air is circulated into the inner heating chamber and diffused through the inner heating chamber to dry the grain inside. During the drying process, the grain is circulated and spread by a vertical conveyor assembly, which causes the grain in the inner heating chamber to flow and promote drying.

[0004] However, due to the large amount of grain piled up between the outer and inner heating chambers, the gravity of the grain will cause greater pressure at the lower end of the vertical conveyor assembly. On the one hand, this can easily cause blockage of the feed inlet at the bottom of the vertical conveyor assembly. On the other hand, the grain is squeezed and piled up, and the gaps between the grains are compressed, which is not conducive to the passage of hot air and affects the drying efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a structure for separating grains and a grain dryer.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] Firstly, a structure for dispersing grain is provided, comprising an outer chamber, an inner heating chamber fixed within the outer chamber, and a vertical conveying assembly penetrating the outer chamber and the inner heating chamber, wherein the vertical conveying assembly includes...

[0008] A vertical conveying pipe extends from the bottom of the outer chamber through the outer chamber and the inner heating chamber to the top of the outer chamber. A dispensing head is provided at the top of the vertical conveying pipe. A grain suction port is provided on the surface of the vertical conveying pipe. A rotating door for sealing the grain suction port is provided at the grain suction port.

[0009] A vertical conveying blade, located inside a vertical conveying pipe, conveys grain from the bottom of the vertical conveying pipe to the top of the vertical conveying pipe.

[0010] A horizontal spiral conveyor assembly, wherein the horizontal spiral conveyor assembly is connected to the bottom end of the surface of the vertical conveyor pipe;

[0011] Also includes

[0012] A stirring assembly is used to stir the grain below the internal heating chamber;

[0013] The diversion assembly includes a rotating diversion disk with multiple diversion openings and an inclined agitator plate disposed at the diversion openings. During the mixing process of the mixing assembly, when rotating in a first direction, the grain discharged through the diversion head is diverted and further dispersed by the agitator plate. When rotating in a second direction, the rotating diversion disk pushes and supports the grain above it upwards, reducing the compression of the grain accumulated below the rotating diversion disk.

[0014] It should be understood that before drying the grain, the grain is first conveyed into the vertical conveyor pipe by the horizontal spiral conveyor assembly via the vertical conveyor blades, and then transported to the spreading head. The spreading head spreads the grain into the outer bin. As the grain falls and passes through the diversion assembly, the diversion port diverts the grain, causing it to flow to multiple locations inside the outer bin, which is beneficial for even stacking. This continues until the grain accumulates near the port of the outer bin, overflowing the diversion assembly. After a period of still drying, the grain in the outer bin is dried by hot air from the internal heating bin. After a certain drying time, once the grain has reached a certain hardness, the grain accumulated in the outer bin is circulated and spread. The specific circulation and spreading process is as follows:

[0015] First, the rotating door removes the seal on the grain suction port, and the vertical conveyor blades begin to transport the grain accumulated at the bottom of the outer bin, passing through the grain suction port, upwards to the spreading head. The spreading head then spreads the grain into the outer bin, achieving the circulation and spreading of the grain in the outer bin. Simultaneously, the rotating diversion plate of the diversion component rotates in the first direction, driving the agitator plate to move synchronously. The upper inclined surface of the agitator plate pushes the grain upwards, and during the continuous rotation, it supports the grain above the diversion component, reducing the pressure of the grain above the diversion component on the grain below the diversion component. This reduces the resistance of the mixing component to the mixing of the grain below the diversion component, and also reduces the blockage of the grain suction port by the grain compression, which is conducive to the smooth circulation and spreading of the grain in the outer bin.

[0016] Then, after the rotating diversion plate of the diversion component rotates in the first direction for a certain period of time, the grain below the diversion component will be reduced under the conveying of the vertical conveying blades. At this time, the rotating diversion plate is adjusted to rotate in the second direction. At this time, the lower inclined surface of the actuating plate will actively push the grain above the diversion component upward, accelerate the grain through the diversion port, fill the space below the diversion component with grain, and replenish the grain in the space below the diversion component. During the replenishment process, the upper inclined surface of the actuating plate and the upper surface of the rotating diversion plate can still support the grain above. The grain above the diversion component is evenly and actively diverted to the lower part of the diversion component through the diversion port, avoiding the accumulation and pressing of the grain above the diversion component, which will cause greater squeezing pressure on the grain below the diversion component.

[0017] During the process of circulating and spreading the grain accumulated in the outer warehouse, the space of the outer warehouse is always divided into upper and lower parts, and the grain in the upper part of the outer warehouse is actively supported. On the one hand, this reduces the resistance of the mixing component to the mixing of the grain below the diversion component, and on the other hand, it reduces the blockage of the grain suction port by the grain compression, which is conducive to the smooth circulation and spreading of the grain in the outer warehouse.

[0018] It should be further explained that during the rotation of the diversion plate of the diversion component in the first direction, the agitator will move and agitate the grain above the diversion component, causing the grain above the diversion component to shake. This shaking of the grain maintains the flow between the grains, which is beneficial for the hot air surging out of the internal heating chamber to flow between the grain above the diversion component after passing through the diversion port of the diversion component, thereby facilitating the uniform drying of the grain by the hot air.

[0019] As an optional technical solution of the present invention, the stirring assembly includes

[0020] Mounting base, which is rotatably connected to the bottom end of the inner heating chamber;

[0021] A stirring blade, which is fixedly connected to the bottom of the mounting base;

[0022] A rotary drive unit is used to drive the mounting base to rotate, thereby driving the stirring blades to stir the grain.

[0023] It should be understood that after a certain period of static drying, during the process of circulating and spreading the grain in the outer chamber, the rotating drive unit drives the installation base and the stirring blade as a whole to rotate, thereby agitating the grain below the diversion component. This facilitates the uniform contact between hot air and grain, which in turn facilitates the rapid drying of the grain.

[0024] As an optional technical solution of the present invention, the rotary drive unit includes...

[0025] The first motor is fixedly installed on the outer wall of the outer compartment. The output end of the first motor is fixedly connected to a drive shaft. The drive shaft passes through the outer compartment and the inner heating compartment in sequence, extends into the inner heating compartment, and is fixedly connected to a drive gear.

[0026] The first gear ring is fixedly connected to the top surface of the mounting base and meshes with the drive gear.

[0027] It should be understood that when stirring is required, the first motor is started, which drives the drive shaft and drive gear to rotate as a whole. The drive gear drives the first gear ring, which in turn drives the mounting base and stirring blade to rotate as a whole, thereby agitating the grain below the diversion component.

[0028] As a further optimized technical solution of the present invention, the current splitting component also includes

[0029] The linkage pipe is rotatably sleeved on the surface of the vertical conveying pipe, with one end fixedly connected to the mounting base and the other end passing through the inner heating chamber and connected to the rotating diverter plate, so as to realize that the linkage pipe and the rotating diverter plate rotate synchronously during the rotation of the rotating diverter plate.

[0030] It should be understood that through the connection of the linkage pipe, while the stirring component is stirring, the rotating distribution plate is driven to rotate. During the stirring process, the stirring blade is first controlled to rotate and stir in the first direction for a certain period of time, and then the stirring blade is controlled to rotate and stir in the second direction. In conjunction with the distribution component, the accumulation state of the grain below the distribution component is controlled, the stirring resistance of the stirring component is reduced, and a certain stable stirring space is reserved below the distribution component.

[0031] As an optional technical solution of the present invention, the toggle plate is provided in a one-to-one correspondence with the diversion port, and a plurality of the diversion ports are distributed in a ring array on the surface of the rotating diversion disk.

[0032] It should be understood that the agitator is set at the diversion outlet and is inclined. When the rotating diversion plate drives the agitator to move in the first direction, it can continuously push the grain at the diversion outlet upward for support. During the process of the rotating diversion plate driving the agitator to rotate in the second direction, the agitator actively pushes the grain at the diversion outlet downward to the diversion outlet, actively diverting the grain from the top of the rotating diversion plate to the bottom of the rotating diversion plate. The agitator and the diversion outlet are evenly distributed on the rotating diversion plate, which can achieve uniform agitation or uniform diversion.

[0033] As a further optimized technical solution of the present invention, the toggle plate is further provided with a flipping component, the flipping component including...

[0034] The mounting slot is formed through the toggle plate;

[0035] A flip plate, which is rotatably connected within a mounting slot;

[0036] A flip-up linkage assembly is used to link the flip-up plate to rotate in a third direction when the rotating diverter plate rotates in a first direction, and to link the flip-up plate to rotate in a fourth direction when the rotating diverter plate rotates in a second direction.

[0037] It should be understood that during the process of the agitator moving to move the grain, the flipping linkage component will be linked to the flipping plate to flip, thereby flipping the grain near the agitator, which is conducive to further enhancing the flow or shaking of the grain and facilitating the flow of hot air between the grains.

[0038] As an optional technical solution of the present invention, the flipping linkage component includes

[0039] A linkage shaft is fixedly connected to the end of the flip plate and is fixedly connected to a first linkage gear after passing through the rotating diverter plate.

[0040] A ring-shaped rack is fixedly connected to the inner side wall of the outer compartment and meshes with the first linkage gear.

[0041] It should be understood that during the rotation of the rotating distributor plate, the first linkage gear will move on the ring rack. During the movement, the first linkage gear will rotate, thereby causing the flip plate to flip.

[0042] As a further optimized technical solution of the present invention, a turbulence component is connected between the rotating diverter disk and the linkage pipe, the turbulence component including...

[0043] A plug-in connector is fixedly connected to the top end of the surface of the linkage pipe, and the rotating diverter is slidably sleeved on the surface of the plug-in connector.

[0044] A support spring, the two ends of which are fixedly connected to the plug-in socket and the rotating diverter, respectively;

[0045] The annular linkage rail includes multiple peak protrusions and multiple trough grooves, and the annular linkage rail is fixedly connected to the top of the inner heating chamber.

[0046] Multiple linkage blocks are set in the trough grooves and are fixedly connected to the bottom surface of the rotating distribution plate.

[0047] It should be understood that during the rotation of the linkage pipe driven by the mounting base, the linkage pipe will synchronously drive the plug-in base to rotate, and the plug-in base will synchronously drive the rotating diverter plate that is slidably plugged into the surface of the plug-in base to rotate synchronously. The rotating diverter plate will synchronously drive the linkage block to rotate. As the linkage block moves from the trough groove to the crest convex, it will lift the rotating diverter plate upward. As the linkage block moves from the crest convex to the trough groove, under the pull of the support spring and its own gravity, the rotating diverter plate will reset and move downward. This process repeats, which not only moves the grain above the diverter assembly, but also the up and down shaking of the rotating diverter plate further enhances the shaking intensity of the grain above the diverter assembly, which is beneficial to the flow of the grain above the diverter assembly.

[0048] As a further preferred technical solution of the present invention, it also includes

[0049] An annular cover is fixedly connected to the inner wall of the outer compartment, and its bottom end slides in contact with the top surface of the rotating diverter to shield the annular rack and the first linkage gear.

[0050] It should be understood that by setting up the annular cover, the annular rack and the first linkage gear are shielded, thus preventing the grain from accumulating at the annular rack and the first linkage gear and causing obstruction.

[0051] In one aspect, a grain dryer is provided, including a structure for dispersing grain, and further comprising...

[0052] A hot air furnace, wherein the air outlet of the hot air furnace extends into the inner heating chamber after passing through the outer chamber and the inner heating chamber in sequence via a pipe;

[0053] A support frame, the top of which is fixedly connected to the hot air furnace and the outer chamber.

[0054] It should be understood that hot air is injected into the inner heating chamber through the hot air furnace to provide a heat source for drying, and the support frame provides support for the hot air furnace and the outer chamber.

[0055] Compared with the prior art, the present invention has the following beneficial effects:

[0056] In this invention, during the process of circulating and spreading the grain accumulated in the outer warehouse, the space of the outer warehouse is always divided into upper and lower parts, and the grain in the upper part of the outer warehouse is actively supported. On the one hand, this reduces the resistance of the stirring component to the stirring of the grain below the diversion component, and on the other hand, it reduces the blockage of the grain suction port by the grain compression, which is conducive to the smooth circulation and spreading of the grain in the outer warehouse.

[0057] In this invention, during the rotation of the diversion plate of the diversion component in the first direction, the agitator moves and agitates the grain above the diversion component, causing the grain above the diversion component to shake. This shaking maintains the flow between the grains, which is beneficial for the hot air surging from the internal heating chamber to flow between the grains above the diversion component after passing through the diversion port of the diversion component, thereby facilitating the uniform drying of the grains by the hot air.

[0058] This invention achieves the following: the rotating diverter is lifted upwards, and as the linkage block moves from the crest to the trough, the rotating diverter returns to its original position and moves downwards under the pull of the support spring and its own gravity. This process repeats, thereby agitating and flowing the grain above the diverter assembly. The up-and-down shaking of the rotating diverter further enhances the shaking intensity of the grain above the diverter assembly, which is beneficial to the flow of the grain above the diverter assembly.

[0073] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0074] like Figures 1 to 13 The illustrated structure for dispersing grain includes an outer chamber 1, an inner heating chamber 2 fixed inside the outer chamber 1, and a vertical conveying assembly penetrating the outer chamber 1 and the inner heating chamber 2. The vertical conveying assembly includes...

[0075] The vertical conveying pipe 3 extends from the bottom of the outer chamber 1 through the inner heating chamber 2 and then to the top of the outer chamber 1. The top of the vertical conveying pipe 3 is equipped with a dispersing head 4. The surface of the vertical conveying pipe 3 is provided with a grain suction port 5. A rotating door 6 is provided at the grain suction port 5 to seal the grain suction port 5.

[0076] Specifically, a discharge pipe 7 is connected to the top side of the vertical conveying pipe 3. A solenoid valve is installed at the connection between the discharge pipe 7 and the vertical conveying pipe 3 to control the connection status between the discharge pipe 7 and the vertical conveying pipe 3.

[0077] Specifically, both the outer chamber 1 and the inner heating chamber 2 are made of perforated galvanized steel sheets, which are breathable.

[0078] Vertical conveyor blade 8 is located inside vertical conveyor pipe 3 and conveys the grain from the bottom of vertical conveyor pipe 3 to the top of vertical conveyor pipe 3.

[0079] A horizontal spiral conveyor assembly is connected to the bottom end of the surface of the vertical conveyor pipe 3;

[0080] Specifically, the horizontal screw conveyor assembly has a horizontal conveying pipe 10 and a feed hopper 9 connected to the horizontal conveying pipe 10. The horizontal conveying pipe 10 is connected to the vertical conveying pipe 3. A horizontal conveying blade 1001 is provided inside the horizontal conveying pipe 10. The horizontal conveying blade 1001 conveys the grain falling from the feed hopper 9 to the vertical conveying pipe 3 to achieve grain feeding.

[0081] Also includes

[0082] A stirring assembly is used to stir the grain below the internal heating chamber 2;

[0083] The diversion assembly includes a rotating diversion disk 11 with multiple diversion ports 12 and an inclined agitator 13 disposed at the diversion ports 12. During the mixing process of the mixing assembly, when rotating in the first direction a, the grain discharged through the dispersing head 4 is diverted and further dispersed by the agitator 13. When rotating in the second direction b, the rotating diversion disk 11 pushes the grain above upward to support it, reducing the compression of the grain accumulated below the rotating diversion disk 11.

[0084] It should be understood that before drying the grain, the grain is first conveyed into the vertical conveying pipe 3 by the horizontal spiral conveyor assembly via the vertical conveyor blades 8, and then transported to the spreading head 4. The spreading head 4 spreads the grain into the outer chamber 1. As the grain falls through the diversion assembly, the diversion port 12 diverts the grain, causing it to flow to multiple locations inside the outer chamber 1, which is beneficial for even stacking. This continues until the grain accumulates near the port of the outer chamber 1, overflowing the diversion assembly. After a period of still drying, the grain in the outer chamber 1 is dried by hot air from the internal heating chamber 2. After a certain drying time, once the grain has reached a certain hardness, the grain accumulated in the outer chamber 1 is circulated and spread. The specific circulation and spreading process is as follows:

[0085] First, the seal on the grain suction port 5 is removed by rotating the rotating door 6. The vertical conveyor blade 8 then begins to transport the grain accumulated at the bottom of the outer bin 1 through the grain suction port 5 upwards to the spreading head 4. The spreading head 4 then spreads the grain into the outer bin 1, achieving the circulation and spreading of the grain in the outer bin 1. At the same time, the rotating diversion plate 11 of the diversion component rotates in the first direction a. The rotating diversion plate 11 drives the agitator plate 13 to move synchronously. The upper inclined surface of the agitator plate 13 will push the grain upwards. During the continuous rotation, it supports the grain above the diversion component, reducing the pressure of the grain above the diversion component on the grain below the diversion component. On the one hand, it reduces the resistance of the mixing component to the mixing of the grain below the diversion component. On the other hand, it reduces the blockage of the grain suction port 5 by the grain compression, which is conducive to the smooth circulation and spreading of the grain in the outer bin 1.

[0086] Then, after the rotating diversion disk 11 of the diversion component rotates in the first direction a for a certain period of time, the grain below the diversion component will be reduced under the conveying of the vertical conveying blade 8. At this time, the rotating diversion disk 11 is adjusted to rotate in the second direction b. At this time, the lower inclined surface of the agitator 13 will actively push the grain above the diversion component upward, accelerate the grain through the diversion port 12, fill the space below the diversion component with grain, and replenish the grain in the space below the diversion component. In the process of replenishment, the upper inclined surface of the agitator 13 and the upper surface of the rotating diversion disk 11 can still support the grain above. The grain above the diversion component is evenly and actively diverted to the lower part of the diversion component through the diversion port 12, so as to avoid the accumulation and pressing of the grain above the diversion component to cause a large squeezing force on the grain below the diversion component.

[0087] During the process of circulating and spreading the grain accumulated in the outer warehouse 1, the space of the outer warehouse 1 is always divided into upper and lower parts, and the grain in the upper part of the outer warehouse 1 is actively supported. On the one hand, this reduces the resistance of the mixing component to the mixing of the grain below the diversion component, and on the other hand, it reduces the blockage of the grain suction port 5 by the grain compression, which is conducive to the smooth circulation and spreading of the grain in the outer warehouse 1.

[0088] It should be further explained that during the rotation of the diversion plate 11 of the diversion component in the first direction a, the agitator 13 will move and agitate the grain above the diversion component, causing the grain above the diversion component to shake. This shakes the grain and maintains the flow between the grains, which is beneficial for the hot air surging out of the inner heating chamber 2 to flow between the grain above the diversion component after passing through the diversion port 12 of the diversion component, thereby facilitating the uniform drying of the grain by the hot air.

[0089] As an optional embodiment of the present invention, the stirring assembly includes

[0090] Mounting base 14 is rotatably connected to the bottom end of the inner heating chamber 2;

[0091] A stirring blade 15 is fixedly connected to the bottom of the mounting base 14.

[0092] A rotary drive unit is used to drive the mounting base 14 to rotate, so as to drive the stirring blade 15 to stir the grain.

[0093] It should be understood that during the process of circulating and spreading the grain in the outer chamber 1 after a certain period of static drying, the rotating drive unit drives the mounting base 14 and the stirring blade 15 to rotate as a whole, thereby agitating the grain below the diversion component by the stirring blade 15. This facilitates the uniform contact between the hot air and the grain, which in turn facilitates the rapid drying of the grain.

[0094] As an optional embodiment of the present invention, the rotary drive unit includes

[0095] The first motor 16 is fixedly installed on the outer wall of the outer chamber 1. The output end of the first motor 16 is fixedly connected to the drive shaft 17. The drive shaft 17 passes through the outer chamber 1 and the inner heating chamber 2 in sequence, extends into the inner heating chamber 2, and is fixedly connected to the drive gear 18.

[0096] The first gear ring 19 is fixedly connected to the top surface of the mounting base 14 and meshes with the drive gear 18.

[0097] It should be understood that when stirring is required, the first motor 16 is started, which drives the drive shaft 17 and drive gear 18 to rotate as a whole. The drive gear 18 drives the first gear ring 19, which in turn drives the mounting base 14 and stirring blade 15 to rotate as a whole, thereby agitating the grain below the diversion component.

[0098] As a further optimized embodiment of the present invention, the shunt component also includes

[0099] Linkage pipe 20 is rotatably sleeved on the surface of vertical conveying pipe 3, with one end fixedly connected to mounting base 14 and the other end passing through inner heating chamber 2 and connected to rotating diverter plate 11, so that linkage pipe 20 and rotating diverter plate 11 rotate synchronously during the rotation of rotating diverter plate 11.

[0100] It should be understood that, through the connection of the linkage pipe 20, while the stirring component is stirring, the rotating diversion plate 11 is driven to rotate. During the stirring process, the stirring blade 15 is first controlled to rotate and stir in the first direction a for a certain period of time, and then the stirring blade 15 is controlled to rotate and stir in the second direction b. In conjunction with the diversion component, the accumulation state of the grain below the diversion component is controlled, the stirring resistance of the stirring component is reduced, and a certain stable stirring space is reserved below the diversion component.

[0101] As an optional embodiment of the present invention, the toggle plate 13 is provided in a one-to-one correspondence with the diversion port 12, and a plurality of diversion ports 12 are distributed in a ring array on the surface of the rotating diversion disk 11.

[0102] It should be understood that the agitator plate 13 is set at the diversion port 12 and is inclined. When the rotating diversion plate 11 drives the agitator plate 13 to move in the first direction a, it can continuously push the grain at the diversion port 12 upward. During the process of the rotating diversion plate 11 driving the agitator plate 13 to rotate in the second direction b, the agitator plate 13 actively pushes the grain at the diversion port 12 downward to the diversion port 12, and actively diverts the grain from the top of the rotating diversion plate 11 to the bottom of the rotating diversion plate 11. The agitator plate 13 and the diversion port 12 are evenly distributed on the rotating diversion plate 11, which can achieve uniform agitation or uniform diversion.

[0103] As a further optimized embodiment of the present invention, the toggle plate 13 is further provided with a flipping assembly, the flipping assembly including...

[0104] The mounting slot is formed through the toggle plate 13;

[0105] Flip plate 21, which is rotatably connected in the mounting groove;

[0106] The flipping linkage component is used to link the flipping plate 21 to rotate in a third direction c when the rotating diverter plate 11 rotates in a first direction a, and to link the flipping plate 21 to rotate in a fourth direction d when the rotating diverter plate 11 rotates in a second direction b.

[0107] It should be understood that during the process of the agitator 13 moving to agitate the grain, the flipping linkage component will be linked to the flipping plate 21 to flip, thereby flipping the grain near the agitator 13, which is conducive to further enhancing the flow or shaking of the grain and facilitating the flow of hot air between the grains.

[0108] As an optional embodiment of the present invention, the flipping linkage component includes

[0109] Linkage shaft 22 is fixedly connected to the end of the flip plate 21, and is fixedly connected to the first linkage gear 23 after passing through the rotating diverter plate 11;

[0110] Specifically, the surface of the rotating distributor 11 is provided with a clearance groove to provide space for the first linkage gear 23;

[0111] The annular rack 24 is fixedly connected to the inner side wall of the outer compartment 1 and meshes with the first linkage gear 23.

[0112] It should be understood that during the rotation of the rotating diverter plate 11, the first linkage gear 23 will move on the ring rack 24. During the movement, the first linkage gear 23 will rotate, thereby causing the flip plate 21 to flip.

[0113] As a further optimized embodiment of the present invention, a turbulence assembly is connected between the rotating distribution plate 11 and the linkage pipe 20. The turbulence assembly includes...

[0114] The plug-in socket 25 is fixedly connected to the top of the surface of the linkage pipe 20, and the rotating diverter 11 is slidably sleeved on the surface of the plug-in socket 25.

[0115] Support spring 26, with its two ends fixedly connected to plug-in socket 25 and rotating diverter 11 respectively;

[0116] The annular linkage rail 27 includes multiple peak protrusions 2701 and multiple trough grooves 2702, and the annular linkage rail 27 is fixedly connected to the top of the inner heating chamber 2.

[0117] Multiple linkage blocks 28 are all set in the trough groove 2702 and are all fixedly connected to the bottom surface of the rotating diverter 11.

[0118] It should be understood that during the rotation of the linkage pipe 20 driven by the mounting base 14, the linkage pipe 20 will synchronously drive the plug-in base 25 to rotate. The plug-in base 25 will synchronously drive the rotating diverter plate 11, which is slidably plugged into the surface of the plug-in base 25, to rotate synchronously. The rotating diverter plate 11 will synchronously drive the linkage block 28 to rotate. During the process of the linkage block 28 moving from the trough groove 2702 to the crest protrusion 2701, the rotating diverter plate 11 will be lifted upward. During the process of the linkage block 28 moving from the crest protrusion 2701 to the trough groove 2702, under the pull of the support spring 26 and its own gravity, the rotating diverter plate 11 will reset and move downward. This process is repeated, so that while the grain above the diverter component is moved and flowed, the up and down shaking of the rotating diverter plate 11 further enhances the shaking intensity of the grain above the diverter component, which is beneficial to the flow of the grain above the diverter component.

[0119] It should be further explained that the agitation component also includes a shielding sleeve 37, which is fitted on the surface of the annular linkage rail 27 and its top end is fixedly connected to the bottom surface of the rotating diverter plate 11 to shield the mating area of ​​the linkage block 28 and the annular linkage rail 27, preventing grain from entering and affecting the mating.

[0120] As a further preferred embodiment of the present invention, it also includes

[0121] The annular cover 29 is fixedly connected to the inner wall of the outer chamber 1, and its bottom end slides in contact with the top surface of the rotating diverter 11 to shield the annular rack 24 and the first linkage gear 23.

[0122] It should be understood that by setting the annular cover 29, the annular rack 24 and the first linkage gear 23 are shielded, thus preventing the grain from accumulating at the annular rack 24 and the first linkage gear 23 and causing obstruction.

[0123] like Figure 1 , Figure 2 and Figure 9 As shown, a grain dryer is provided, including a structure for spreading grain, and also including...

[0124] The hot air furnace 30 has its air outlet passing through the outer chamber 1 and the inner heating chamber 2 in sequence via pipes and then extending into the inner heating chamber 2.

[0125] The top of the support frame 31 is fixedly connected to the hot air furnace 30 and the outer chamber 1.

[0126] It should be understood that hot air is injected into the inner heating chamber 2 through the hot air furnace 30 to provide a heat source for drying, and the support frame 31 is set up to support the hot air furnace 30 and the outer chamber 1.

[0127] It should be specifically noted that the bottom end of the vertical conveying pipe 3 is provided with a first rotary drive assembly, which includes a second motor 32 and a belt drive assembly 33. The second motor 32 is fixedly mounted on the support frame 31. The output end of the second motor 32 is connected to the connecting shaft of the vertical conveying blade 8 through the belt drive assembly 33, thereby providing rotational power for the rotation of the vertical conveying blade 8.

[0128] The rotating door 6 is fitted onto the surface of the linkage pipe 20, and the lower end of the rotating door 6 passes through the outer chamber 1 and is fixedly connected to the second linkage gear 34 below the outer chamber 1. The second linkage gear 34 is meshed with a rack plate 35. An electric cylinder 36 is fixedly installed between the rack plate 35 and the support frame 31. When circulation is required in the outer chamber 1, the electric cylinder 36 is activated to linearly drive the rack plate 35. The rack plate 35 drives the second linkage gear 34 to rotate, which in turn drives the rotating door 6 to rotate and cancel the seal on the grain suction port 5.

[0129] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
