Description

Technical Field

[0001] This utility model belongs to the field of drying boxes, and specifically relates to a wheat drying device. Background Technology

[0002] Wheat typically needs to be dried and stored after harvesting; otherwise, its high moisture content can lead to mold growth, reducing its quality and even rendering it inedible or unmarketable. Furthermore, dried wheat is less susceptible to pests, reducing the risk of infestation. During wind-drying of wheat, poor hot air conduction, uneven airflow, and uneven material distribution all hinder drying efficiency. In addition, existing drying equipment has several shortcomings. Some devices use a single hot air delivery method, with hot air entering the chamber from a fixed location without an effective airflow guide structure. This results in chaotic airflow within the chamber, failing to evenly cover the wheat and significantly extending drying time. Simultaneously, traditional equipment has an unreasonable material feeding design; wheat poured directly into the drying chamber tends to clump together, making it difficult to fully contact the hot air. Even with extended drying time, it's difficult to ensure uniform drying, affecting subsequent storage and processing. Moreover, some drying equipment is complex to operate, requiring significant time and manpower for loading and unloading, hindering efficient operations and limiting production efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a wheat drying device. By setting an upper connecting rod opening and closing mechanism and a lower connecting rod opening and closing mechanism, the upper and lower openings of the wheat storage trough in the drying box are opened and closed. By setting an air inlet and a ventilation baffle, hot air can penetrate the wheat in the storage trough and increase the contact area between the wheat and the air, thereby improving the drying efficiency. This utility model has a reasonable structural design, is easy to operate, has no redundancy, and has high reliability.

The second beveled rod has a horizontal axis coaxial with the second rotating shaft, which is rotatably engaged with a through hole on the other side of the lower part of the box. The second beveled rod also has a horizontal axis not coaxial with the second rotating shaft, which is rotatably engaged with a through hole on the side of the second connecting rod.

[0008] The uniformly distributed material guiding mechanism is located above the drying box and includes a feed inlet, a buffer section, and a material distribution section. The buffer section has an inclined material guiding plate, and the material distribution section has a pair of partition plates. Each set of partition plates corresponds to a wheat storage trough, and a material leveling plate is provided between each set of partition plates. The top view projection of the lower edge of the material leveling plate divides the length direction of the top view projection of the corresponding wheat storage trough equally.

[0009] The air guide connector includes a circular inlet end and a rectangular outlet end that are connected to each other, and an air guide plate; the circular inlet end is connected to the air outlet of the hot air blower, and the rectangular outlet end is connected to the front side of the box and fully covers the slot of the air inlet trough opened on the front side of the box; wherein the air guide plate is located in the channel between the circular inlet end and the rectangular outlet end, and is used to guide and distribute the air force.

[0010] In the lower connecting rod opening and closing mechanism, the throttle includes an integrally formed upper limit post, lower limit post, rotating post, bearing rod, and second grip; the upper surface of the second connecting rod has a through circular hole, and the rotating post passes through the circular hole, with the diameter of the rotating post matching the inner diameter of the circular hole; the upper limit post is located on the upper surface of the second connecting rod, and the lower limit post is located on the lower surface of the second connecting rod, with both dimensions larger than the diameter of the through hole to restrict the axial movement of the rotating post; the bearing rod has a cylindrical structure, and when the lower connecting rod opening and closing mechanism is in the closed state, the lower end face of the bearing rod is in contact with the upper surface of the support block.

[0011] The upper connecting rod opening and closing mechanism also includes a first handle at both ends of the upper surface of the first connecting rod, and an extension integrally formed with the side of the rotating cover plate away from the first rotating axis in the width direction.

[0012] A windproof fixing plate is provided above the air inlet trough. The upper surface of the windproof fixing plate has a slot corresponding to the lower side of the isolation plate, and the lower part of the isolation plate is inserted into the slot. A rotating groove that runs through the length of the windproof fixing plate is provided at one end of the width direction of the windproof fixing plate near the through hole at the top of the box.

[0013] The upper side of the non-rotating groove end of the windbreak fixing plate in the width direction is provided with a rounded corner; when the upper connecting rod opening and closing mechanism is in the closed state, the extension of the rotating cover plate abuts against the top of the rounded corner.

[0014] A receiving hopper with a wide top and a narrow bottom is provided at the bottom of the box.

[0015] Beneficial effects: 1. By setting up a uniformly distributed material guiding mechanism, in which the inclined material guiding plate in the buffer section and the paired isolation plates and uniform material plate in the distribution section cooperate, the wheat is evenly distributed to each wheat storage tank, avoiding material accumulation and ensuring full contact between the wheat and hot air, effectively improving the uniformity and efficiency of drying. 2.

[0032] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. For example... Figure 1-15As shown, the technical solution adopted by this utility model is: a wheat drying device, including a workbench 1, a hot air blower 2 installed above the workbench 1, a drying box 3, an upper connecting rod opening and closing mechanism 4, a lower connecting rod opening and closing mechanism 5, a uniformly distributed material guiding mechanism 6, and an air guiding connector 7; the hot air blower 2 is installed above the workbench 1 to ensure that the air outlet of the hot air blower 2 is easy to connect with the subsequent air guiding connector 7, so as to ensure that the hot air can be delivered smoothly;

[0033] The drying box 3 includes a box body 31. Five to twelve identical wheat storage troughs 32 are provided on the top of the box body 31, penetrating the box body 31. Air inlet and wheat blowing troughs 33 are provided on the sides of the front side of the box body 31 corresponding to each wheat storage trough 32. A ventilation baffle 34 is provided between the wheat storage trough 32 and the corresponding air inlet and wheat blowing trough 33. Each ventilation baffle 34 has through holes. A support block 35 is provided on the rear side of the box body 31. The through holes on the ventilation baffle 34 are used for hot air conduction. The through holes adopt a sieve-like structure and their size is significantly smaller than the average grain size of wheat. This ensures effective hot air penetration while preventing wheat from leaking out of the through holes.

[0034] An upper connecting rod opening and closing mechanism 4 is provided above the opening of the wheat storage trough 32. The upper connecting rod opening and closing mechanism 4 includes a rotating cover plate 41, a first rotating shaft 42, a first curved rod 43, and a first connecting rod 44. The number of rotating cover plates 41, the first rotating shaft 42, and the first curved rod 43 corresponds to the number of wheat storage troughs 32. Each rotating cover plate 41 is fixedly connected to the first rotating shaft 42 at one end and to the first curved rod 43 at the other end. The first rotating shaft 42 is rotatably engaged with a through hole on one side of the upper part of the box body 31. The first curved rod 43 has a horizontal axis coaxial with the first rotating shaft 42, which is rotatably engaged with a through hole on the other side of the upper part of the box body 31. The first curved rod 43 also has a horizontal axis not coaxial with the first rotating shaft 42, which is rotatably engaged with a through hole on the side of the first connecting rod 44. The upper connecting rod opening and closing mechanism 4 is used to control the opening and closing of the opening of the wheat storage trough 32. Figure 9 This is a schematic diagram of the upper connecting rod opening and closing mechanism 4 and the lower connecting rod opening and closing mechanism 5 changing from the open to the closed state. During the wheat feeding stage, the operator holds the first handle 45 and applies force to the left side of the drying box 3, which drives the first connecting rod 44 to move to the left side of the drying box 3. This causes the first rotating shaft 42, the first crank rod 43 and the horizontal axis coaxial with the first rotating shaft 42 to rotate, thereby opening the rotating cover 41 and allowing the wheat to fall into the wheat storage trough 32. During the drying process, the operator holds the first handle 45 and applies force to the right side of the drying box 3, which drives the first connecting rod 44 to move to the right side of the drying box 3 and closes the rotating cover 41. This prevents hot air from leaking out and ensures a stable drying environment.

[0035] A lower connecting rod opening and closing mechanism 5 is provided below the opening of the wheat storage trough 32. The lower connecting rod opening and closing mechanism 5 includes a rotating support plate 51, a second rotating shaft 52, a second beveled rod 53, a second connecting rod 54, and a handle 55. The number of rotating support plates 51, second rotating shafts 52, and second beveled rods 53 corresponds to the number of wheat storage troughs 32. Each rotating support plate 51 is fixedly connected to the second rotating shaft 52 at one end and to the second beveled rod 53 at the other end. The second rotating shaft 52 is rotatably engaged with a through hole on one side of the lower part of the box body 31. The second beveled rod 53 has a horizontal axis coaxial with the second rotating shaft 52, which is rotatably engaged with a through hole on the other side of the lower part of the box body 31. The second beveled rod 53 also has a horizontal axis not coaxial with the second rotating shaft 52, which is rotatably engaged with a through hole on the side of the second connecting rod 54. The lower connecting rod opening and closing mechanism 5 is responsible for opening and closing the opening below the opening of the wheat storage trough 32.

[0036] The uniformly distributed material guiding mechanism 6 is located above the drying chamber 3, and includes an inlet 61, a buffer section 62, and a distribution section 63. An inclined guide plate 64 is arranged inside the buffer section 62, and paired isolation plates 65 are provided inside the distribution section 63. Each set of isolation plates 65 corresponds to a wheat storage trough 32, and a leveling plate 66 is provided between each set of isolation plates 65. The top-view projection of the lower edge of the leveling plate 66 equally divides the length of the top-view projection of the corresponding wheat storage trough 32. The inlet 61 is used to receive and dry the wheat, which passes through the inclined guide plate in the buffer section 62. The 64 buffer deceleration prevents wheat from accumulating at the feed inlet 61 and preventing it from being discharged. The material is then divided into a corresponding number of wheat storage troughs 32 by paired isolation plates 65 in the distribution section 63. The wheat is then evenly distributed by the uniform distribution plate 66 between each set of isolation plates 65. The lower edge of the uniform distribution plate 66 divides the top projection of the corresponding wheat storage trough 32 equally in the top projection direction, thereby ensuring that the wheat is evenly distributed in each wheat storage trough 32 and that there is no partial bulging after the wheat falls into the wheat storage trough 32. This ensures the practicality and applicability of this utility model.

[0037] The air guide connector 7 includes a circular inlet end 71 and a rectangular outlet end 72 connected to each other, and an air guide plate 73. The circular inlet end 71 is connected to the air outlet of the hot air blower 2, and the rectangular outlet end 72 is connected to the front side of the housing 31, and fully covers the slot of the air inlet trough 33 opened on the front side of the housing 31. The air guide plate 73 is located in the channel between the circular inlet end 71 and the rectangular outlet end 72, and is used to guide and distribute the air force.

[0038] In the lower connecting rod opening and closing mechanism 5, the handle 55 includes an integrally formed upper limit post 551, lower limit post 552, rotating post 553, bearing rod 554, and second grip 555. A through circular hole is formed on the upper surface of the second connecting rod 54, and the rotating post 553 passes through this circular hole, with its diameter matching the inner diameter of the hole. The upper limit post 551 is located on the upper surface of the second connecting rod 54, and the lower limit post 552 is located on the lower surface of the second connecting rod 54. Both are larger than the diameter of the through hole to restrict the axial movement of the rotating post 553. The bearing rod 554 is cylindrical; when the lower connecting rod opening and closing mechanism 5 is in the closed state, the lower end face of the bearing rod 554 is in contact with the upper surface of the support block 35. After the wheat is dried, the operator rotates the handle 55, specifically by holding the second grip 555 and rotating it counterclockwise. At this time, the bearing rod 554 disengages from the support block 35, and the wheat trough 32... The downward pressure of the wheat causes the second rotating shaft 52, the second crank rod 53, and the horizontal axis coaxial with the second rotating shaft 52 to rotate, opening the rotating bearing plate 51 downwards. This allows the dried wheat to fall smoothly and be collected by the receiving hopper 8, thus achieving the unloading function. When the lower connecting rod opening and closing mechanism 5 is in the closed state, the lower end face of the bearing rod 554 is tightly fitted with the upper surface of the support block 35 on the rear side of the box 31, forming a stable support structure to bear the weight of the wheat in the wheat storage trough 32 and the pressure generated during the drying process. Here, the bearing rod 554 is a cylindrical structure. When the handle 55 drives the lower connecting rod opening and closing mechanism 5, its circular surface makes the rotation smoother, reduces friction and resistance, and helps to improve the unloading efficiency. In addition, in order to enable the lower connecting rod opening and closing mechanism 5 to bear the weight of the wheat in the wheat storage trough 32, while ensuring the stability and reliability of the mechanism, the lower connecting rod opening and closing mechanism 5 should be made of high-strength metal materials.

[0039] The upper connecting rod opening and closing mechanism 4 also includes first handles 45 located at both ends of the upper surface of the first connecting rod 44, and an extension 46 integrally formed with the side of the rotating cover 41 away from the first rotating axis 42 in the width direction; the function of the extension 46 is that when the rotating cover 41 is closed, the extension 46 abuts against the upper side of the windproof fixing plate 36, providing support for the closing of the rotating cover 41, such as Figure 11 As shown in the enlarged view at point B, when the rotating cover 41 is opened, the extension 46 abuts against the partition plate 65. At this time, the rotating cover 41 is in an inclined state, as shown... Figure 11 As shown in the enlarged view at point C, this design prevents the rotating cover 41 from closing during feeding, which is beneficial to the scientific rationality and practicality of this utility model.

[0040] A windproof fixing plate 36 is provided above the air inlet trough 33. The upper surface of the windproof fixing plate 36 has a slot 361 corresponding to the lower side of the isolation plate 65. The lower part of the isolation plate 65 is inserted into the slot 361. A rotating groove 362 is provided at one end of the windproof fixing plate 36 near the upper through hole of the box 31 in the width direction, which penetrates the length direction of the windproof fixing plate 36. The windproof fixing plate 36 cooperates with the rotating cover plate 41 to prevent hot air from leaking out. The insertion of the lower part of the isolation plate 65 into the slot 361 is beneficial to the stability of this utility model.

[0041] The upper side of the non-rotating groove 362 end of the windbreak fixing plate 36 in the width direction is provided with a rounded corner; when the upper connecting rod opening and closing mechanism 4 is in the closed state, the extension 46 of the rotating cover plate 41 abuts against the top of the rounded corner; when the upper connecting rod opening and closing mechanism 4 is in the open state, if this part is not rounded, the wheat is easy to accumulate on the windbreak fixing plate 36 when it is fed, which will cause the rotating cover plate 41 to not close tightly when it is closed later. The rounded corner design allows the material to slide down smoothly, ensuring that the rotating cover plate 41 opens and closes smoothly and closes tightly. This design is beneficial to the scientific rationality and practicality of this utility model.

[0042] The box 31 is provided with a receiving hopper 8 that is wide at the top and narrow at the bottom. The wide top opening is convenient for receiving the dried wheat that falls from the wheat storage trough 32 after the lower connecting rod opening and closing mechanism 5 is opened, so as to prevent the wheat from spilling outside the box 31. The narrow bottom opening can concentrate the wheat, so that the wheat can be smoothly and quickly collected at the outlet, which is convenient for subsequent unified collection and transfer.

[0043] Among the above, bushings can be installed in the through holes provided on the housing 31, the first connecting rod 44, and the second connecting rod 54, so that the rotation between the shaft and the through hole is smoother.

[0044] The specific working principle is as follows: The wheat fed into the feed inlet 61 is buffered by the inclined guide plate 64 of the buffer section 62, separated by the isolation plate 65 of the distribution section 63, and evenly distributed by the uniform plate 66, so that it enters the wheat storage trough 32 evenly and orderly. The upper connecting rod opening and closing mechanism 4 controls the opening and closing of the rotating cover plate 41 to realize the opening and closing of the trough opening of the wheat storage trough 32, which facilitates feeding and prevents hot air leakage during drying. The lower connecting rod opening and closing mechanism 5 is responsible for controlling the opening and closing of the rotating support plate 51 below the trough opening of the wheat storage trough 32. During drying, the hot air fan 2 is started, and the hot air enters through the circular inlet end 71 of the air guide connector 7. After being guided by the air guide plate 73, it is evenly sent to the air inlet wheat trough 33 from the rectangular outlet end 72. Then, the hot air penetrates into the wheat storage trough 32 through the through holes of the ventilation partition 34 to fully contact the wheat and accelerate drying. After drying, the lower connecting rod opening and closing mechanism 5 is operated to open the rotating support plate 51, so that the dried wheat falls into the receiving hopper 8 to complete the unloading.
