Description

Technical Field

[0001] This invention relates to the field of grain processing technology, and in particular to a grain drying equipment with automatic sorting and discharging function. Background Technology

[0002] When grains get damp, they can become infested with insects, moldy, or sprout, which can lead to spoilage. Therefore, grains need to be dried before storage and transportation.

[0003] A search revealed Chinese patent publication number CN111964418B, which discloses grain drying equipment, including a grain drying device and its driving subsystem. The grain drying device includes a bottom support base, with a support assembly at the upper end of the bottom support base. A feeding component and a drying component are sequentially arranged at the upper end of the support assembly. A receiving box is also provided at the upper end of the bottom support base. The bottom support base is a square block. The support assembly includes a first support group, a second support group, a third support group, and a fourth support group fixedly connected to the upper end of the bottom support base. The first, second, third, and fourth support groups are arranged sequentially, and each is a square support column.

[0004] The aforementioned patent has the following shortcomings: it cannot increase the gap between grain particles when drying grains, resulting in a smaller amount of hot air blown into the gaps between the grains. The smaller amount of air means that, under the same hot air temperature, the amount of heat energy contained is less, resulting in lower grain drying efficiency.

[0005] Therefore, this invention proposes a grain drying device with automatic sorting and discharging function. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grain drying device with automatic sorting and discharging functions.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A grain drying device with automatic sorting and discharging function includes an inclined conveying and drying chamber, a hopper located at the top of the conveying and drying chamber, a sorting and guiding unloading section located on the side of the conveying and drying chamber, a heat convection drying section located on the side wall of the conveying and drying chamber, a filter section located inside the conveying and drying chamber, and a transmission section located on one side of the conveying and drying chamber for driving the filter section.

[0009] The conveying and drying chamber includes a hollow cylinder and end caps fixedly installed at both ends of the hollow cylinder;

[0010] The filter cake section includes a main shaft and a filter plate fixedly installed on the side wall of the main shaft; the main shaft is movably connected to the end cover through a bushing;

[0011] The transmission unit includes a transmission housing and a bidirectional drive assembly, a transfer assembly, and a drive assembly disposed inside the transmission housing;

[0012] The bidirectional drive assembly includes a rocker arm fixedly installed on the outer wall of the spindle and a pad fixedly installed on the outer wall of the rocker arm. A rod is movably inserted into the inner wall of the pad, and a swing arm is fixedly installed on the side wall of the rod. A shaft is fixedly installed at the other end of the swing arm.

[0013] Preferably, the inner wall of the spindle is provided with a keyway, and the bushing is fitted to the outside of the keyway through a key-shaped protrusion, and the bushing is rotatably connected to the inner wall of the end cover.

[0014] Furthermore, the bidirectional drive component adopts a two-set design.

[0015] Based on the aforementioned scheme: a material collection hood is fixedly installed on the outer wall of the end cap at one of the discharge ports, and a material discharge pipe is fixedly installed on the other end of the material collection hood. The material discharge pipe is fixedly installed on the outer wall of the end cap at the discharge port.

[0016] A preferred embodiment of the aforementioned scheme is as follows: the transfer assembly includes an input gear one and an input gear two, which are respectively fixedly installed on the outer walls of the two shafts. One side of the input gear one is meshed with a transfer gear, and one side of the input gear two is meshed with a double-toothed gear ring. The inner side of the double-toothed gear ring is meshed with a planetary gear, and the inner side of the planetary gear is meshed with a sun gear. One side of the planetary gear is rotatably connected to a planetary carrier via a rotating shaft, and the planetary carrier is fixedly installed on the outer wall of the transfer shaft.

[0017] As a further aspect of the present invention: the driving component is an electric motor, which is fixedly installed on the outer wall of the transmission box, and the output shaft of the electric motor is connected to the inner wall of the sun gear by a key.

[0018] Meanwhile, the filter cake section also includes a ventilation plate, which is fixedly installed on the bottom inner wall of the hollow cylinder.

[0019] As a preferred embodiment of the present invention: the sorting and guiding feeding section includes a second feeding pipe and a first feeding pipe. The inner wall of the first end cap located at the feeding point is provided with a first discharge port. A baffle is movably installed on the inner wall of the first discharge port. The baffle is fixedly installed on the side wall of the filter plate. A flexible cloth is adhered to the bottom of the baffle. The other end of the flexible cloth is adhered to the inner wall of the first discharge port. The bottom of the first end cap is provided with a second discharge port.

[0020] Meanwhile, a material collection hood is fixedly installed on the outer wall of the end cap at one of the discharge ports, and a material discharge pipe is fixedly installed on the other end of the material collection hood. The material discharge pipe is fixedly installed on the outer wall of the end cap at the discharge port.

[0021] As a preferred embodiment of the present invention: the heat convection drying section includes two air vents opened at the bottom and top of the hollow cylinder, and the outer walls of the two air vents are fixedly installed with air hoods. The air hoods are connected to the same heat pump through air ducts, and the airflow direction of the heat pump is from top to bottom.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The present invention, by setting up a filter plate and a bidirectional drive assembly, utilizes the reciprocating oscillation of the filter plate to achieve grain scattering, and the scattered grains can collide with each other, thereby increasing the gap between the grain pieces and increasing the drying efficiency.

[0024] 2. In this invention, by setting up a filter plate, the grain can be filtered during the drying process. Moreover, during filtration, the filter plate is driven by the same power as the grain scattering function, which can realize the axial reciprocating motion of the filter plate and increase the filtration efficiency.

[0025] 3. In this invention, by setting two sets of bidirectional drive components with their shafts rotating in opposite directions, the center of the torque, i.e., the zero point of the torque, is located on the axis of the main shaft when the bidirectional drive components apply torque to the pad through the insert rod. This prevents the main shaft from experiencing additional bending moment in addition to the driving torque, thereby preventing main shaft deformation and improving its lifespan.

[0026] 4. In this invention, by setting up a drive assembly, the single drive of the sun gear in the drive assembly is distributed to the planet gear and the double-toothed ring gear chain. This utilizes the dual degrees of freedom of the planet gear's revolution and the double-toothed ring gear's rotation to achieve an equal distribution of the driving force at both ends, while ensuring that they are at the same speed and in opposite directions. This effectively prevents damage to components caused by uneven driving force due to internal stress. Furthermore, the dual-output transmission forms a closed transmission, further ensuring the driving ratio of the distribution.

[0027] 5. This invention, by setting up a classification-guided feeding section, can filter grains while drying them, and the filtered finished product and impurities can be collected separately, increasing its functionality.

[0028] 6. This invention utilizes the characteristics of filter plates and ventilation plates to introduce drying hot air from bottom to top. On the one hand, this increases the relative path between the hot air and the grain, and on the other hand, it removes low-density impurities from the grain with the airflow, further increasing drying efficiency and impurity removal effect.

Detailed Implementation

[0039] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0040] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0041] Example 1:

[0042] A grain drying device with automatic sorting and discharging function, such as Figure 1-9 As shown, it includes an inclined conveying and drying chamber 1, a hopper 4 located at the top of the conveying and drying chamber 1, a sorting and guiding unloading section 3 located on the side of the conveying and drying chamber 1 at a low position, a heat convection drying section 2 located on the side wall of the conveying and drying chamber 1, a filter section 6 located inside the conveying and drying chamber 1, and a transmission section 5 located on one side of the conveying and drying chamber 1 for driving the filter section 6.

[0043] The conveying and drying chamber 1 includes a hollow cylinder 7 and end caps 8 that are fixed to both ends of the hollow cylinder 7 by bolts.

[0044] The filter cake section 6 includes a main shaft 10 and a filter plate 11 welded to the side wall of the main shaft 10; the main shaft 10 is movably connected to the end cover 8 via a bushing 9.

[0045] The transmission unit 5 includes a transmission box and a bidirectional drive assembly 13, a transfer assembly 14, and a drive assembly 15 disposed inside the transmission box.

[0046] The bidirectional drive assembly 13 includes a rocker arm 16 welded to the outer wall of the main shaft 10 and a pad 17 fixed to the outer wall of the rocker arm 16 by bolts. A rod 20 is movably inserted into the inner wall of the pad 17, and a swing arm 19 is fixed to the side wall of the rod 20 by bolts. A shaft 18 is welded to the other end of the swing arm 19.

[0047] When shaft 18 rotates, it can drive the insertion rod 20 to rotate through the swing arm 19. The insertion rod 20 and the pad block 17 then drive the rocker arm 16 to rotate and slide, thereby driving the main shaft 10 and the filter plate 11 to rotate and slide. When the filter plate 11 rotates, it can scatter the grain located on the filter plate 11. Furthermore, the reciprocating swing of the filter plate 11 can also cause the scattered grain to collide with each other.

[0048] This device, by setting up a filter plate 11 and a bidirectional drive assembly 13, uses the reciprocating swing of the filter plate 11 to scatter the grain, and the grain can collide after scattering, thereby increasing the gap between the grain pieces and increasing the drying efficiency.

[0049] In addition, by setting up the filter plate 11, it can also filter the grain during the drying process. Moreover, during filtration, it is driven by the same power as the grain scattering function, which can realize the axial reciprocating motion of the filter plate 11, thereby increasing the filtration efficiency.

[0050] To solve connectivity problems; such as Figure 4 As shown, the inner wall of the main shaft 10 is provided with a keyway 42, and the bushing 9 is fitted to the outside of the keyway 42 through the key-shaped protrusion 41. The bushing 9 is rotatably connected to the inner wall of the end cover 8.

[0051] To solve the problem of partial motion; such as Figure 1 , 7 As shown, firstly, this embodiment does not limit the number of bidirectional drive components 13, and can be designed as one or two groups. Based on this, this embodiment preferably adopts a two-group design for the bidirectional drive components 13.

[0052] Secondly, the transfer assembly 14 includes an input gear 28 and an input gear 29 respectively welded to the outer walls of the two shafts 18. One side of the input gear 28 is meshed with a transfer gear 27, and one side of the input gear 29 is meshed with a double-toothed ring gear 24. The inner side of the double-toothed ring gear 24 is meshed with a planetary gear 23, and the inner side of the planetary gear 23 is meshed with a sun gear 22. One side of the planetary gear 23 is rotatably connected to a planet carrier 25 via a rotating shaft. The planet carrier 25 is welded to the outer wall of the transfer shaft 26.

[0053] In this embodiment, the specific type of the drive component 15 is not limited. Preferably, the drive component 15 is an electric motor 21, which is fixed to the outer wall of the transmission box by bolts, and the output shaft of the electric motor 21 is connected to the inner wall of the sun gear 22 by a key.

[0054] When the motor 21 starts, it drives the sun gear 22 to rotate, thereby providing driving force for the revolution of the planet gear 23 and the rotation of the double-toothed ring gear 24. The driving force of the revolution of the planet gear 23 can be transmitted to the transfer gear 27 through the planet carrier 25, and then to one of the shafts 18 through the input gear 28. The driving force of the rotation of the double-toothed ring gear 24 can be transmitted to the other shaft 18 through the input gear 29, thereby driving the two shafts 18 to rotate in opposite directions.

[0055] This device, by setting two sets of bidirectional drive components 13, with the shafts 18 of the two sets of bidirectional drive components 13 rotating in opposite directions, ensures that when the bidirectional drive components 13 apply torque to the pad 17 through the insert rod 20, the center of the torque, that is, the zero point of the torque, is located on the axis of the main shaft 10. This prevents the main shaft 10 from experiencing additional bending moment in addition to the driving torque, thereby preventing deformation of the main shaft 10 and improving its service life.

[0056] In addition, this device, by setting up a drive assembly 15, utilizes the single drive of the sun gear 22 in the drive assembly 15 to drive the planet gear 23 and the double toothed ring gear 24, thereby using the two degrees of freedom of the revolution of the planet gear 23 and the rotation of the double toothed ring gear 24 to achieve the equal distribution of the driving force at both ends, and ensure that they are in the same speed and opposite direction. This can effectively prevent the components from being damaged by internal stress due to uneven driving force, and the dual-output transmission forms a closed transmission, thereby further ensuring the driving ratio of the distribution.

[0057] To solve the filtering problem; such as Figure 3 As shown, the filter residue section 6 also includes a ventilation plate 12, which is fixed to the bottom inner wall of the hollow cylinder 7 by bolts; the impurities filtered by the filter plate 11 will fall to the top of the ventilation plate 12, and the pores inside the ventilation plate 12 are small, so the impurities cannot pass through.

[0058] To solve the problem of sorting and cutting materials, such as Figure 9 As shown, the classification guide feeding part 3 includes a second feeding pipe 39 and a first feeding pipe 38. The inner wall of the end cap 8 located at the feeding point is provided with a discharge port 34. A baffle 35 is movably installed on the inner wall of the discharge port 34. The baffle 35 is welded to the side wall of the filter plate 11. A flexible cloth 36 is bonded to the bottom of the baffle 35. The other end of the flexible cloth 36 is bonded to the inner wall of the discharge port 34. A second feeding port 37 is provided at the bottom of the end cap 8.

[0059] The outer wall of the end cap 8 located at the discharge port 34 is fixed with a material collection hood 40 by bolts. The other end of the material collection hood 40 is welded with a discharge pipe 39. The outer wall of the end cap 8 located at the discharge port 37 is fixed with a discharge pipe 38 by bolts.

[0060] As the grain is continuously scattered and filtered, the finished product will roll down the filter plate 11 to the baffle 35, and then enter the collection hood 40. It will be discharged through the discharge pipe 2 39, while impurities will pass through the ventilation plate 12 and the discharge port 2 37, and be discharged through the discharge pipe 1 38.

[0061] This device, by setting up a classification and guiding feeding section 3, can filter the grain while drying it, and the finished product and impurities can be collected separately after filtration, which increases its functionality.

[0062] In this embodiment, when the motor 21 starts, it drives the sun gear 22 to rotate, thereby providing driving force for the revolution of the planetary gear 23 and the rotation of the double-toothed ring gear 24. The driving force of the revolution of the planetary gear 23 can be transmitted to the transfer gear 27 through the planet carrier 25, and to one of the shafts 18 through the input gear 1 28. The driving force of the rotation of the double-toothed ring gear 24 can be transmitted to the other shaft 18 through the input gear 29, thereby driving the two shafts 18 to rotate in opposite directions. When shaft 18 rotates, the insertion rod 20 can be driven to rotate through the swing arm 19, thereby driving the rocker arm 16 to rotate and slide through the cooperation of the insertion rod 20 and the pad 17, thereby driving the main shaft 10 and the filter plate 11 to rotate and slide. When the filter plate 11 rotates, it can scatter the grain located on the filter plate 11, and the reciprocating swing of the filter plate 11 can also cause the scattered grain to collide. The finished product after drying and filtering is discharged through the discharge pipe 2 39, and impurities are discharged through the discharge pipe 1 38.

[0063] Example 2:

[0064] A grain drying device with automatic sorting and discharging function, such as Figure 1 , 8 As shown, in order to solve the drying problem, this embodiment makes the following improvements based on embodiment 1: The heat convection drying section 2 includes two air vents 30 opened at the bottom and top of the hollow cylinder 7. The outer walls of the two air vents 30 are welded with air covers 31. The air covers 31 are connected to the same heat pump 33 through air pipes 32, and the air direction of the heat pump 33 is from top to bottom.

[0065] In this embodiment, when the heat pump 33 is started, it can draw out the air at the top, heat it, and then input it from the bottom, thereby passing through the ventilation plate 12 and the filter plate 11.

[0066] This device, by utilizing the characteristics of the filter plate 11 and the ventilation plate 12, introduces the drying hot air from bottom to top. On the one hand, this increases the relative path between the hot air and the grain, and on the other hand, it removes the less dense impurities in the grain with the airflow, further increasing the drying efficiency and impurity removal effect.

[0067] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
