Description

Technical Field

[0001] This invention relates to the field of agricultural product drying equipment technology, and in particular to an agricultural product sterilization and drying machine. Background Technology

[0002] The drying or dehydration of agricultural products is collectively referred to as agricultural product drying, and the resulting products are called dried agricultural products. Agricultural product dry storage refers to methods that, under natural or artificial conditions, reduce the moisture content of agricultural products to a level sufficient to prevent spoilage and maintain this low moisture content for long-term storage. With advancements in drying technology, the nutritional value of dried products will become increasingly similar to that of fresh agricultural products; therefore, the prospects for agricultural product drying are promising, and it has great potential.

[0003] However, due to issues with the selection of raw materials during production, it cannot be guaranteed that all selected agricultural raw materials are of acceptable quality, and there is a possibility of moldy agricultural raw materials being mixed in. Furthermore, traditional drying processes are not equivalent to sterilization; moldy raw materials can also be dried to form substandard dried products, directly affecting the quality of dried agricultural products. Summary of the Invention

[0004] The purpose of this invention is to provide an agricultural product sterilization and drying machine that can hold different types or sizes of agricultural products in different trays. At the same time, it can achieve efficient and energy-saving drying and sterilization of agricultural products by using the transmission connection formed by the hot air drying component, the turbulence component, the ultraviolet sterilization component and the concentric material tray component.

[0005] The objective of this invention is achieved through the following technical solution: an agricultural product sterilization and drying machine, comprising a main housing assembly, a concentric feeding tray assembly, a turbulence-inducing component, a hot air drying assembly, and an ultraviolet sterilization assembly. The main housing assembly includes a bottom plate, the concentric feeding tray assembly includes an inner tray and a tray rotating gear, the turbulence-inducing component includes a turbulence fan, a turbulence gear, and a flow-around connecting gear, the hot air drying assembly includes an outer conical tooth ring, a hot air duct, and a blower, and the ultraviolet sterilization assembly includes a rotating roller, a conveyor belt, and an ultraviolet lamp strip. The top of the bottom plate is covered with a cover body. The bottom end of the inner plate is screwed to the center of the bottom plate. The top of the bottom plate is also screwed with a middle plate and an outer plate. The inner plate is connected to the middle plate, and the middle plate is connected to the outer plate. The bottom of the bottom plate is provided with a rotatable plate drive gear. The plate rotation gear is inserted into the rotation shaft at the bottom of the inner plate and meshes with the plate drive gear. The turbulence fan is screwed into the inner middle of the inner plate. The rotation shaft of the turbulence fan rotates downward and is fixed with the turbulence gear. The plate drive gear is connected to the turbulence gear through a flow-connecting gear. The inclined hot air ducts are symmetrically fixed to both ends of the main body of the fixed cover. The outer bevel gear ring is fixed to the outside of the outer plate. Each set of hot air ducts has a blower bevel gear screwed to the lower inner end. Each set of blower bevel gears has a transmission bevel gear meshing on the lower side. Both sets of transmission bevel gears mesh with the outer bevel gear ring. The blower fan is fixed to the outer end of the transmission bevel gear. The top two sides of the base plate are symmetrically screwed with rotating rollers, and one set of rotating rollers is connected to the outer bevel gear ring drive. The conveyor belt is sleeved between the two sets of rotating rollers, and an ultraviolet light strip is installed on the outside of the conveyor belt.

[0006] The process of using the technical solution of the present invention is as follows: Different types or the same type of agricultural products of different sizes can be placed in the inner, middle and outer trays as needed. After the heat emission mechanism inside the hot air duct is turned on, the inner disc can be rotated through the cooperation of the rotating disc drive gear and the disc rotation gear. The inner disc drives the middle disc to rotate in the opposite direction through the transmission mechanism. The middle disc drives the outer disc to rotate in the opposite direction through the transmission mechanism, thereby realizing the rotation of agricultural products in the inner, middle and outer discs. When the outer disc rotates, it can drive the outer bevel gear ring to rotate, so that the outer bevel gear ring and the transmission bevel gear can cooperate and drive each other. The transmission bevel gear drives the rotation of the blower bevel gear, which in turn drives the rotation of the blower fan located inside the hot air duct. The fan's rotation generates aerodynamics, which can extract heat from the inside of the outer conical ring and blow air in the direction of the inner, middle, and outer discs. Since the inner, middle, and outer discs are all in a rotating state, the blown air containing heat can completely cover agricultural products in any location. Simultaneously, the disc drive gear also drives the turbulence gear to rotate at a speed higher than the disc rotating gear through the flow connection gear, thereby making the turbulence fan rotate at a speed higher than the inner disc, which can turbulent the air in the space between the solid cover and the bottom solid plate, so that the hot air blown out from the lower end of the hot air duct can be widely distributed to the agricultural products placed in the inner disc, middle disc and outer disc. After the ultraviolet light strip is turned on, the outer conical tooth ring rotates, which in turn drives the conveyor belt to rotate. This causes the intermittently distributed ultraviolet light strip to move along the rolling path of the conveyor belt, and in conjunction with the rotation of the inner, middle, and outer discs, irradiate the surface of agricultural products at any position. This reduces the amount of ultraviolet light strips used, achieving energy saving, while simultaneously sterilizing the agricultural products inside the inner, middle, and outer discs with ultraviolet light.

[0007] By adopting the above technical solution, the present invention has the following beneficial effects: (1) The present invention has an inner plate, a middle plate and an outer plate that are connected to each other from the inside to the outside at the top of the bottom plate. Different kinds or sizes of agricultural products to be dried can be placed in the inner plate, the middle plate and the outer plate to achieve the purpose of classified drying. At the same time, the inner plate, the middle plate and the outer plate can be rotated, so as to provide a basis for agricultural products in different positions to be in direct contact with the hot air blown from the lower end of the self-heating air duct. (2) The rotational power of the blower inside the hot air tube of the present invention also comes from the outer disc body, which can drive the outer bevel gear ring to cooperate with the transmission bevel gear when the outer disc body rotates, thereby enabling the transmission bevel gear to rotate at high speed relative to the outer bevel gear ring, and thus enabling the transmission bevel gear to drive the rotation of the blower through the blower bevel gear, so that the rotation of the blower drives the heat inside the hot air tube to form hot air that blows onto the surface of the inner disc body, the middle disc body and the outer disc body, forming a source of dry hot air; (3) In order to achieve the turbulence operation of hot air in the internal space formed by the bottom plate and the solid cover, the present invention also has a turbulence component connected between the inner middle part of the inner plate and the plate drive gear. This allows the plate drive gear to drive the inner plate to rotate through the plate rotating gear, and at the same time, it can drive the turbulence fan to rotate through the cooperation formed with the flow connecting gear and the turbulence gear. Thus, the hot air blown straight out from the lower end of the hot air tube can be evenly distributed to the surface of the inner plate, the middle plate and the outer plate by utilizing the rotation speed of the turbulence fan which is higher than that of the inner plate. This improves the drying efficiency and achieves the purpose of energy saving. (4) Furthermore, the present invention adopts the method of fixing the ultraviolet light strip to the outside of the rotatable conveyor belt. With the rotation of the outer conical tooth ring, the conveyor belt that covers the top surface of the outer, middle and inner discs can also rotate. Thus, the ultraviolet light strip installed outside the conveyor belt can be used to form ultraviolet irradiation sterilization operation on all positions of the top surface of the outer, middle and inner discs along the rolling path of the conveyor belt.

[0013] like Figures 1-12 As shown, an agricultural product sterilization and drying machine includes a bottom solid plate 101 in the main housing assembly 1 with a solid cover 103 at the top. The bottom end of the inner disc 201 is screwed to the center of the bottom solid plate 101. A middle disc 205 and an outer disc 207 are sequentially screwed to the top of the bottom solid plate 101 from the inside out. The middle disc 205 and the outer disc 207 are concentrically arranged with the inner disc 201. The inner disc 201 is drive-connected to the middle disc 205, and the middle disc 205 is drive-connected to the outer disc 207. The bottom end of the plate 101 is provided with a rotatable disc drive gear 216. The disc rotation gear 214 is inserted into the rotating shaft at the bottom end of the inner disc 201 and meshes with the disc drive gear 216. The deflector fan 302 is screwed into the inner middle part of the inner disc 201. After the rotating shaft of the deflector fan 302 rotates downward, it is fixed with the deflector gear 304. The disc drive gear 216 is connected to the deflector gear 304 through the flow-connecting gear 305, which allows the deflector fan 302 to rotate at a speed higher than that of the inner disc 201. The inclined hot air ducts 402 are symmetrically fixed to both ends of the main body of the fixed cover 103. The outer bevel gear ring 401 is fixed to the outside of the outer disc 207. Each set of hot air ducts 402 has a blower bevel gear 405 screwed to its inner lower end. Each set of blower bevel gear 405 has a transmission bevel gear 404 meshing on its lower side. Both sets of transmission bevel gears 404 mesh with the outer bevel gear ring 401. The blower fan 409 is fixed to the outer end of the transmission bevel gear 404. The rotation of the outer disc 207 can drive the rotation of the blower 409 through the transmission mechanism, so that the heat generated in the hot air tube 402 is blown into the outer disc 207, the middle disc 205 and the inner disc 201; The top two sides of the bottom plate 101 are symmetrically screwed with rotating rollers 502, and one set of rotating rollers 502 is connected to the outer conical tooth ring 401 for transmission. The conveyor belt 503 is sleeved between the two sets of rotating rollers 502. An ultraviolet lamp strip 504 is installed on the outside of the conveyor belt 503. The length of the ultraviolet lamp strip 504 can be increased or decreased according to the requirements. With the rotation of the inner plate 201, the middle plate 205 and the outer plate 207, ultraviolet light is irradiated to any position on the main surface of the inner plate 201, the middle plate 205 and the outer plate 207. Different types or the same type of agricultural products of different specifications can be placed in the inner tray 201, the middle tray 205 and the outer tray 207 according to the needs, so that different types or specifications of agricultural products can be dried at one time. After the heat emission mechanism inside the hot air duct 402 is turned on, the inner disc 201 can be rotated through the cooperation of the rotatable disc drive gear 216 and the disc rotation gear 214. The inner disc 201 drives the middle disc 205 to rotate in the opposite direction to the inner disc 201 through the transmission mechanism. The middle disc 205 drives the outer disc 207 to rotate in the opposite direction to the middle disc 205 through the transmission mechanism, thereby realizing the rotation of agricultural products in the inner disc 201, middle disc 205 and outer disc 207. When the outer disc 207 rotates, it can drive the outer bevel gear ring 401 to rotate, so that the outer bevel gear ring 401 and the transmission bevel gear 404 form a transmission engagement. The transmission bevel gear 404 drives the rotation of the blower bevel gear 405, which in turn drives the rotation of the blower fan 409 located inside the hot air duct 402. The fan 409 rotates to generate air power, which can extract heat from the inside of the outer conical ring 401 and blow the inner disc 201, middle disc 205 and outer disc 207 in the direction of rotation. Since the inner disc 201, middle disc 205 and outer disc 207 are all in a rotating state, the blown air containing heat can completely cover the agricultural products in any position. Simultaneously, the disc drive gear 216 also drives the turbulence gear 304 to rotate at a speed higher than that of the disc rotating gear 214 through the flow connection gear 305, thereby making the turbulence fan 302 rotate at a speed higher than that of the inner disc 201. This can turbulent the air in the space between the solid cover 103 and the bottom solid plate 101, so that the hot air blown out from the lower end of the hot air duct 402 can be widely distributed to the agricultural products placed in the inner disc 201, the middle disc 205 and the outer disc 207. After the ultraviolet light strip 504 is turned on, the outer conical tooth ring 401 rotates, and the transmission mechanism drives the conveyor belt 503 to rotate. This causes the intermittently distributed ultraviolet light strip 504 to roll along the path of the conveyor belt 503, and in conjunction with the rotation of the inner disc 201, middle disc 205 and outer disc 207, irradiate the surface of agricultural products at any position. This reduces the number of ultraviolet light strips 504, achieving energy saving, while simultaneously performing ultraviolet irradiation sterilization on the agricultural products in the inner disc 201, middle disc 205 and outer disc 207.

[0014] The specific structure of main enclosure component 1 is as follows: Figure 2 As shown, the bottom surface of the base plate 101 is fixedly connected to the support leg 102 for supporting and placing the device. A bottom retainer 104 with a circular ring structure is fixedly connected to the outer top of the bottom plate 101. The bottom retainer 104 has bottom grooves 106 symmetrically opened on both sides of its main body. The inner card seat 105 is symmetrically fixedly connected to both sides of the inner bottom end of the fixed cover 103, and as the fixed cover 103 is fixedly connected to the top of the bottom fixed plate 101, the bottom opening of the fixed cover 103 can be snapped into the bottom card sleeve 104, and the inner card seat 105 on the same side can be snapped into the bottom card groove 106, so that the fixed cover 103 will not twist during the process of being connected and fixed with the bottom fixed plate 101. Side handles 107 are symmetrically fixed to both sides of the outer side of the cover 103 to facilitate the movement of the cover 103 when it is disassembled.

[0015] The specific structures of the concentric feeding tray assembly 2 and the turbulence-disrupting component 3 are as follows: Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a central shaft seat 212 is installed at the bottom of the main body of the bottom plate 101, and the bottom of the inner disc 201 is rotatably connected to the central shaft seat 212. An inner spiral toothed ring 202 is fixed on the outer side of the main body of the inner disc 201, and a middle inner toothed ring 206 is fixed on the inner side of the main body of the middle disc 205. A set of internal conversion gears 204 mesh between the middle inner toothed ring 206 and the inner spiral toothed ring 202. An inner conversion shaft 203 is fixedly connected to the top of the bottom plate 101, and the inner conversion gears 204 on the same side are rotatably connected in the inner conversion shaft 203. The middle external gear ring 208 is fixedly connected to the outer side of the main body of the middle disc 205, and the external gear ring 211 is fixedly connected to the inner side of the main body of the outer disc 207. A set of external conversion gears 210 mesh between the middle external gear ring 208 and the external gear ring 211. An external conversion shaft 209 is fixedly connected to the top of the bottom plate 101, and the external conversion gears 210 on the same side are rotatably connected in the external conversion shaft 209. A disc drive motor 215 is fixedly installed at the bottom end of the base plate 101, and a disc drive gear 216 is inserted and fixed in the rotating shaft of the disc drive motor 215. The bottom of the main body of the middle plate 205 and the outer plate 207 are fixedly connected with bottom sliding balls 217 around their own rotation center. The top of the bottom plate 101 is fixedly connected with a spherical slide track 218. The middle plate 205 and the outer plate 207 are slidably connected in the spherical slide track 218 through the bottom sliding balls 217 connected at their bottom ends. The central spiral hole 213 is opened through the middle of the main body of the inner disc 201; Furthermore, through holes are provided in the bottom surfaces of the inner disc 201, the middle disc 205, and the outer disc 207 to facilitate air circulation; The corner structure spoiler shaft seat 303 is fixedly connected to the bottom end of the base plate 101. The spoiler shaft 301 is rotatably connected in the spoiler shaft seat 303, and the top end of the spoiler shaft 301 is fixedly connected to the spoiler fan 302 after being rotated upward from the central swivel hole 213. The turbulence gear 304 is inserted and fixed to the bottom end of the turbulence shaft 301, and the flow-around connecting gear 305 is screwed to one side of the bottom end of the turbulence shaft seat 303, and the flow-around connecting gear 305 meshes between the disc drive gear 216 and the turbulence gear 304. After the disk drive motor 215 is started and drives the disk drive gear 216 to rotate, the disk drive gear 216 can simultaneously mesh with the disk rotating gear 214 and the flow-connecting gear 305, thereby driving the inner disk 201 to rotate at a low speed through the transmission ratio formed by the disk rotating gear 214 and the disk drive gear 216. On the other hand, the turbulence gear 304 can drive the turbulence shaft 301 to rotate at high speed through the transmission ratio formed by the flow-connecting gear 305 and the disk drive gear 216, thereby driving the turbulence fan 302 to maintain high-speed rotation in the opposite direction to the inner disk 201, forming a more effective turbulence effect. Furthermore, when the inner disc 201 rotates, it can drive the inner helical gear ring 202 to rotate. The inner helical gear ring 202 drives the middle inner gear ring 206 to rotate in the opposite direction to the inner helical gear ring 202 through a uniformly distributed array of internal conversion gears 204, thereby making the middle disc 205 rotate in the opposite direction to the inner disc 201. The middle disc 205 drives the rotation of the middle external gear ring 208. The middle external gear ring 208 drives the external gear ring 211 to rotate in the opposite direction to the middle external gear ring 208 through a uniformly distributed array of external conversion gears 210, thereby enabling the outer disc 207 to rotate in the opposite direction to the middle disc 205. This allows the outer disc 207, the middle disc 205, and the inner disc 201 to rotate in opposite directions, and also achieves the purpose of multi-directional spatial position change of agricultural products in the inner disc 201, the middle disc 205, and the outer disc 207, thereby improving the drying and sterilization effect to a certain extent.

[0016] The specific structure of the hot air drying component 4 is as follows: Figure 7 and Figure 8 As shown, the drive shaft seat 403 is fixedly connected to the lower oblique end of the hot air duct 402, the drive shaft 406 is rotatably connected in the drive shaft seat 403, and the drive bevel gear 404 is inserted and fixed in the drive shaft 406. Each set of hot air ducts 402 has a cross-shaped blower shaft seat 407 fixed at its inner lower end. A blower shaft 408 is rotatably connected in the blower shaft seat 407. A blower bevel gear 405 is inserted and fixed at one end of the blower shaft 408, and a blower fan 409 is inserted and fixed at the other end of the blower shaft 408. Each set of hot air tubes 402 is covered with an outer cover 410 at its upper end. An electric heating wire 411 is fixedly installed on the inner surface of the outer cover 410, which can generate heat and enter the inner cavity of the solid cover 103 after being drawn by the self-blowing fan 409. Furthermore, the main body of the blower bevel gear 405 has a through hole to facilitate air circulation; After the heating wire 411 is turned on, heat is generated. The suction force generated by the rotation of the fan 409 can draw the heat generated by the heating wire 411 through the through hole of the blower bevel gear 405 and blow it onto the surface of the outer plate 207, the middle plate 205 and the inner plate 201. The heat is also drawn through the air vents in the outer cover 410 body to form an air circulation effect.

[0017] The specific structure of the ultraviolet sterilization component 5 is as follows: Figure 9 and Figure 10 As shown, the support 501 is symmetrically fixedly connected to both sides of the top end of the base plate 101, and the rotating roller 502 is rotatably connected to the top end of the support 501. The horizontal connecting seat 505 is fixedly connected to the lower part of one set of upright seats 501 in the horizontal direction. The horizontal shaft 506 is rotatably connected in the horizontal connecting seat 505. The rolling connecting bevel gear 507 is inserted and fixed in the inner end of the horizontal shaft 506 and meshes with the outer bevel gear ring 401. A lateral bevel gear 508 is fixed to the outer end of a set of rollers 502 on the same side as the rolling bevel gear 507. A reversing bevel gear 509 meshes with one side of the lateral bevel gear 508, and the reversing bevel gear 509 is connected to the rolling bevel gear 507 in a transmission connection. A rotating pulley 510 is inserted and fixed to the outer end of the horizontal shaft 506. A reversing shaft seat 511 is fixedly connected to the outer end of a set of uprights 501 on the same side as the rolling connecting bevel gear 507. A reversing shaft 512 is rotatably connected in the reversing shaft seat 511. A reversing bevel gear 509 is inserted and fixed to one end of the reversing shaft 512. A reversing connecting pulley 513 is inserted and fixed to the other end of the reversing shaft 512. A connecting belt 514 is sleeved and installed between the reversing connecting pulley 513 and the rotating pulley 510. When the outer bevel ring 401 rotates with the outer disc 207, it can drive the outer bevel ring 401 to form a transmission with the rolling connecting bevel gear 507. The rolling connecting bevel gear 507 drives the rotation of the rotating pulley 510 coaxially through the horizontal shaft 506. The rotating pulley 510 drives the rotation of the reversing connecting pulley 513 through the connecting belt 514. This allows the reversing connecting pulley 513 to drive the rotation of the reversing bevel gear 509 coaxially through the reversing shaft 512. The reversing bevel gear 509 and the lateral bevel gear 508 work together to drive the conveyor belt 503, which is sleeved between the two sets of rotating rollers 502, to roll in a cycle. This causes the ultraviolet lamp strip 504 installed outside the conveyor belt 503 to irradiate different positions on the surfaces of the outer disc 207, the middle disc 205 and the inner disc 201 as the conveyor belt 503 rolls.

[0018] The specific structure of the box cover component 6 is as follows: Figure 11 As shown, a flip connecting arm 603 is fixedly connected to the outer top of the box cover 601, and a flip base 602 is fixedly connected to the middle of one side of the top of the fixed cover 103. The flip connecting arm 603 is hinged in the flip base 602, which can realize the opening and closing of the box cover 601. Furthermore, after the lid 601 is closed, it forms a complete structure with the fixed cover 103 and is fastened in the bottom sleeve 104, which conveniently creates a relatively closed space inside the lid 601, the fixed cover 103 and the bottom fixed plate 101. A flip handle 604 is fixedly connected to the outside of the lid 601 to facilitate the opening and closing of the lid 601.

[0019] Preferably, a lamp wiping component 7 is also fixedly installed on the inner top surface of the cover 601. The cleaning block seat 701 is fixedly connected to the inner top surface of the cover 601 at the position directly opposite the ultraviolet lamp strip 504.
