Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing technology, specifically to a drying device for agricultural product processing. Background Technology

[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties. The state stipulates that primary agricultural products refer to plants, animals and their products obtained from agricultural activities, excluding processed products. Agricultural products need to be dried during processing.

[0003] A search revealed Chinese patent application number 202420690110.4, which discloses a drying device for agricultural product processing, relating to the field of agricultural product processing technology. This drying device includes a drying chamber with an exhaust pipe fixedly connected to its right end. The drying chamber contains a drying unit, which includes a drying section. The drying section comprises an air pump, a sealing sleeve, a motor, a main air pipe, branch air pipes, a first bevel gear, and a second bevel gear. This drying device, by incorporating an air pump, main air pipe, branch air pipes, an arc-shaped plate, a first bevel gear, a motor, a second bevel gear, and a sealing sleeve, draws air from outside the drying chamber into the air pump, allowing the gas to pass through the main air pipe and branch air pipes into the drying chamber. The motor, activated by the first and second bevel gears, drives the main air pipe and branch air pipes to rotate, agitating the agricultural products inside the drying chamber, widening the gaps between the products, and facilitating gas passage through these gaps for drying.

[0004] The problem with existing technology is that existing agricultural product drying equipment lacks material lifting function. It can only stir laterally to expand the gap between materials, but cannot lift the bottom material upwards. As a result, the material in the drying box always accumulates at the bottom and is loose at the top. When the load is large, the bottom material is squeezed by gravity, and the effect of the branch pipe rotation to expand the gap is limited. The hot airflow only acts on the upper layer, and the bottom material needs to be dried for a longer time because the airflow is difficult to penetrate, which affects the overall drying efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a drying device for agricultural product processing, which has the advantage of being able to lift materials, thereby improving drying efficiency. This solves the problem that existing agricultural product processing drying equipment lacks a lifting function, can only horizontally stir to widen the gaps between materials, and cannot lift the bottom material upwards. As a result, the material in the drying chamber always accumulates at the bottom and is loose at the top. When the load is large, the bottom material is squeezed by gravity, the effect of the branch pipe rotation to widen the gaps is limited, the hot airflow only acts on the upper layer, and the bottom material needs to be dried for a longer time because the airflow is difficult to penetrate, which affects the overall drying efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for agricultural product processing, comprising a base and a vertical plate, the bottom of the vertical plate being fixedly connected to the base, the drying mechanism comprising a shell, the top of the shell being fixedly connected to an exhaust port, and the inner cavity being provided with a material lifting assembly, while the right side is provided with a heating assembly.

[0007] As a preferred embodiment of this utility model, the lifting assembly includes a rotating cylinder, with a drive shaft fixedly connected to the left side of the rotating cylinder and a lifting plate fixedly connected to the inner wall.

[0008] As a preferred embodiment of this utility model, the end of the drive shaft away from the rotating cylinder passes through the housing and extends to the outside of the housing, and a rotating plate is sleeved on its surface; The number of lifting plates is multiple, and they are evenly distributed in a ring array; The outer surface of the rotating cylinder is provided with exhaust holes, and there are multiple exhaust holes, which are evenly distributed in a ring array.

[0009] In a preferred embodiment of this invention, the rotating plate is located on the inner side of the top of the upright plate and is rotatably connected to the upright plate, while a drive motor is fixedly connected to the left side. The output end of the drive motor is fixedly connected to the transmission shaft, and the left side of the housing is fixedly connected to the rotating plate.

[0010] In a preferred embodiment of this utility model, the heating assembly includes a cover plate, the front side of which is rotatably connected to the housing, and the rear side of which is fixedly connected to the housing by bolts. A heating box is fixedly connected to the right side of the heating box, and a fan is fixedly connected to the right side of the heating box.

[0011] As a preferred embodiment of this invention, an electric heating tube is fixedly connected to the inner cavity of the heating box, a protective net is fixedly connected to the right side of the fan, and a connecting block is fixedly connected to the bottom of the shell.

[0012] As a preferred embodiment of this utility model, a hydraulic cylinder is rotatably connected to the inner side of the connecting block, and an mounting block is rotatably connected to the end of the hydraulic cylinder away from the connecting block, with the bottom of the mounting block fixedly connected to the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem of existing agricultural product processing drying equipment lacking material lifting function by setting up a drying mechanism. It can only stir laterally to expand the gap between materials, but cannot lift the bottom material upwards. As a result, the material in the drying box always accumulates at the bottom and is loose at the top. When the load is large, the bottom material is squeezed by gravity, and the effect of the branch pipe rotation to expand the gap is limited. The hot airflow only acts on the upper layer, and the bottom material needs to be dried for a longer time because the airflow is difficult to penetrate, which affects the overall drying efficiency. This utility model achieves the effect of lifting the material and improving the drying efficiency.

[0014] 2. This utility model, by setting up a lifting component, realizes all-round turning of materials and rapid discharge of moisture, improving drying uniformity and efficiency. Multiple ring array lifting plates rotate at high speed with the rotating drum, which can lift the bottom material upward and then evenly scatter it, breaking the material accumulation layer, so that the hot airflow can fully contact each material. The drying time of the bottom material is the same as that of the top layer, and the exhaust holes on the outer surface of the rotating drum can discharge the moisture evaporated during the turning of the material.

[0015] 3. This utility model achieves a stable and clean supply of hot air by setting up a heating component. The electric heating tube and the fan work together to generate stable constant temperature hot air. The hot air is delivered to the shell through the heating box and can quickly remove moisture. The protective net on the right side of the fan can prevent foreign objects from being sucked in and avoid damage to the fan. The design of the cover plate with a rotating connection on the front side and bolt fixing on the rear side makes it easy to open the shell to take out or put in materials. Meanwhile, the angle of the drying mechanism can be adjusted by means of hydraulic cylinders, connecting blocks and mounting blocks to adapt to different unloading requirements. The hydraulic cylinder can push the shell to rotate around the rotating plate to adjust the tilt angle of the drying mechanism. During drying, the horizontal angle is maintained to ensure that the material is turned over evenly. During unloading, the tilt angle is increased so that the dried agricultural products slide out along the inner wall of the rotating drum. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0022] Example 1 Reference Figure 1-3 This is the first embodiment of the present invention, which provides a drying device for agricultural product processing, including a base 1 and a vertical plate 2. The bottom of the vertical plate 2 is fixedly connected to the base 1, and a drying mechanism 3 is provided on the top of the base 1. The drying mechanism 3 includes a housing 31, with an exhaust port 32 fixedly connected to the top of the housing 31, a material lifting assembly 33 provided in the inner cavity, and a heating assembly 34 provided on the right side.

[0023] Specifically, by setting up drying mechanism 3, the problem of existing agricultural product processing drying equipment lacking material lifting function is solved. It can only stir laterally to expand the gap between materials, but cannot lift the bottom material upwards. As a result, the material in the drying box always accumulates at the bottom and is loose at the top. When the load is large, the bottom material is squeezed by gravity, and the effect of the branch pipe rotation to expand the gap is limited. The hot airflow only acts on the upper layer, and the bottom material needs to be dried for a longer time because the airflow is difficult to penetrate, which affects the overall drying efficiency. The solution achieves the effect of lifting the material and improving the drying efficiency.

[0024] Furthermore, the heating component 34 generates constant-temperature hot air, which is delivered into the housing 31. The lifting component 33 lifts and disperses the material accumulated at the bottom, allowing the hot air to fully contact each material, accelerating moisture evaporation. The moisture generated by evaporation is discharged from the housing 31 through the exhaust port 32, preventing moisture accumulation that could cause the material to become damp again. At the same time, the tilt angle of the housing 31 can be adjusted by the hydraulic cylinder 10. During drying, the housing 31 is kept horizontal to ensure that the material is turned over evenly. When unloading, the tilt angle is increased to facilitate the rapid discharge of the dried material, thus improving processing efficiency.

[0025] Example 2 In the second embodiment of this utility model, the lifting assembly 33 includes a rotating cylinder 331, a drive shaft 332 is fixedly connected to the left side of the rotating cylinder 331, and a lifting plate 333 is fixedly connected to the inner wall.

[0026] The end of the drive shaft 332 away from the rotating cylinder 331 passes through the housing 31 and extends to the outside of the housing 31, and a rotating plate 4 is sleeved on its surface; There are multiple lifting plates 333, which are evenly distributed in a ring array; The outer surface of the rotating cylinder 331 is provided with exhaust holes 5. There are multiple exhaust holes 5, which are evenly distributed in a ring array.

[0027] The rotating plate 4 is located on the inner side of the top of the upright plate 2 and is rotatably connected to the upright plate 2. The drive motor 6 is fixedly connected to the left side. The output end of the drive motor 6 is fixedly connected to the transmission shaft 332. The left side of the housing 31 is fixedly connected to the rotating plate 4.

[0028] Specifically, by setting up the lifting assembly 33, the material is turned over in all directions and the moisture is discharged quickly, which improves the drying uniformity and efficiency. The lifting plates 333 of the multiple ring array rotate at high speed with the rotating drum 331, which can lift the bottom material up and then scatter it evenly, breaking the material accumulation layer, so that the hot airflow can fully contact each material. The drying time of the bottom material is the same as that of the top layer, and the exhaust hole 5 on the outer surface of the rotating drum 331 can discharge the moisture evaporated during the material turning process.

[0029] Furthermore, the drive motor 6 is started, which drives the transmission shaft 332 to rotate. The transmission shaft 332 drives the rotating drum 331 to rotate synchronously. The lifting plate 333 on the inner wall of the rotating drum 331 rotates with the rotating drum 331. When the lifting plate 333 rotates to the bottom of the shell 31, it contacts the material and scoops it up. As the rotating drum 331 continues to rotate, the lifting plate 333 carries the material up to a certain height. Under the action of gravity, the material slides off the surface of the lifting plate 333 and is evenly scattered in the inner cavity of the shell 31. During this process, the moisture in the material is heated and evaporated. The generated moisture enters the gap between the shell 31 and the rotating drum 331 through the exhaust hole 5 on the surface of the rotating drum 331 and is finally discharged through the exhaust port 32 at the top of the shell 31.

[0030] Example 3 In the second embodiment of this utility model, the heating component 34 includes a cover plate 341. The front side of the cover plate 341 is rotatably connected to the housing 31, while the rear side is fixedly connected to the housing 31 by bolts. A heating box 342 is fixedly connected to the right side of the heating box 342, and a fan 343 is fixedly connected to the right side of the heating box 342.

[0031] An electric heating tube 7 is fixedly connected to the inner cavity of the heating box 342, a protective net 8 is fixedly connected to the right side of the fan 343, and a connecting block 9 is fixedly connected to the bottom of the shell 31.

[0032] A hydraulic cylinder 10 is rotatably connected to the inner side of the connecting block 9. A mounting block 11 is rotatably connected to the end of the hydraulic cylinder 10 away from the connecting block 9. The bottom of the mounting block 11 is fixedly connected to the base 1.

[0033] Specifically, by setting up the heating component 34, a stable and clean hot air supply is achieved. The electric heating tube 7, in conjunction with the fan 343, can generate stable constant temperature hot air. The hot air is delivered to the housing 31 through the heating box 342, which can quickly remove moisture. The protective net 8 on the right side of the fan 343 can prevent foreign objects from being sucked in and avoid damage to the fan 343. The design of the cover plate 341 with a rotating connection on the front and a bolt fixation on the rear side makes it easy to open the housing 31 to take out or place materials. Meanwhile, the angle of the drying mechanism 3 can be adjusted by the hydraulic cylinder 10, the connecting block 9 and the mounting block 11 to adapt to different unloading requirements. The hydraulic cylinder 10 can push the housing 31 to rotate around the rotating plate 4 to adjust the tilt angle of the drying mechanism 3. During drying, the horizontal angle is maintained to ensure that the material is turned over evenly. During unloading, the tilt angle is increased so that the dried agricultural products slide out along the inner wall of the rotating drum 331.

[0034] Furthermore, during heating, the fan 343 and the electric heating tube 7 are started. The fan 343 draws outside air into the heating box 342. The air is heated to the set temperature by the electric heating tube 7 to form constant temperature hot air. The hot air is delivered into the shell 31 through the opening on the left side of the heating box 342, and comes into full contact with the material being turned over by the lifting assembly 33, accelerating the evaporation of moisture in the material. The moisture generated by evaporation is discharged through the exhaust port 5 of the rotating drum 331 and the exhaust port 32 at the top of the shell 31. The protective net 8 blocks foreign objects when the fan 343 draws in air, preventing damage to the fan 343. When loading and unloading materials, loosen the bolts on the back of the cover plate 341, open the cover plate 341, and you can add the material to be dried or take out the dried material into the shell 31. After drying is completed, the hydraulic cylinder 10 is started, the cylinder output shaft retracts, and the connecting block 9 is pulled downward, causing the housing 31 to rotate around the rotating plate 4. The rotating cylinder 331 tilts synchronously with the housing 31. Under the action of gravity, the dried material slides along the inner wall of the rotating cylinder 331 to the lower end of the housing 31 and is discharged from the opened cover plate 341. After unloading is completed, the output shaft of the hydraulic cylinder 10 extends, causing the housing 31 to return to the horizontal angle, ready for the next round of drying.

[0035] Working principle: During operation, loosen the bolts on the rear side of the cover plate 341 of the heating component 34, open the cover plate 341, pour the agricultural products to be dried evenly into the rotating drum 331 of the shell 31, close the cover plate 341, tighten the bolts on the rear side, and complete the loading. During the loading process, the hydraulic cylinder 10 remains extended and the shell 31 is at a horizontal angle, which facilitates the even distribution of materials. After loading is completed, the output shaft of the hydraulic cylinder 10 remains extended and the housing 31 maintains a horizontal angle. This angle allows the material to be evenly lifted and scattered when the lifting assembly 33 rotates, avoiding the material from being tilted to one side due to the tilt of the housing 31, which would affect the uniformity of lifting. At the same time, the horizontal angle ensures that the hot air is evenly distributed inside the housing 31. Then, the fan 343 and electric heating tube 7 of the heating component 34 are started. The fan 343 draws outside air into the heating box 342. The air is heated to a suitable temperature by the electric heating tube 7 to form constant temperature hot air. The hot air is delivered to the rotating drum 331 through the heating box 342 to contact the material. The fan 343 runs continuously to ensure a stable supply of hot air. At the same time, the drive motor 6 of the lifting assembly 33 is started. The drive motor 6 drives the transmission shaft 332 and the rotating drum 331 to rotate. The lifting plate 333 on the inner wall of the rotating drum 331 lifts the bottom material upward as it rotates. After the material rises to a suitable height, it falls under the action of gravity, breaking up the accumulation layer, so that each piece of material can fully contact the hot air. During the contact between the hot air and the material, the hot air absorbs the moisture in the material to achieve drying. The lifting assembly 33 continues to operate to ensure that the material is always in a turning state during the drying process, avoiding local overheating or uneven drying. The moisture generated by the evaporation of the material is pushed by hot air and enters the gap between the shell 31 and the rotating cylinder 331 through the exhaust hole 5 on the surface of the rotating cylinder 331. Then the moisture flows upward and is discharged to the outside of the equipment through the exhaust port 32 at the top of the shell 31. After the material is dried, turn off the fan 343, electric heating tube 7 and drive motor 6, loosen the bolts on the back of cover plate 341, open cover plate 341, start hydraulic cylinder 10, the cylinder output shaft retracts, pulls connecting block 9 downward, drives housing 31 to rotate around rotating plate 4, causing housing 31 to tilt, rotating cylinder 331 tilts with housing 31, dried material slides along the inner wall of rotating cylinder 331 to the lower end of housing 31, and is discharged from the opening of cover plate 341 to the external collection container. After unloading, control the output shaft of hydraulic cylinder 10 to extend, drive housing 31 to return to the horizontal angle, turn off hydraulic cylinder 10, clean the residual material in housing 31, and prepare for the next round of drying.

[0036] In summary, by setting up drying mechanism 3, the material can be lifted, thus improving drying efficiency.
