Description

Technical Field

[0001] This invention relates to the field of drying equipment for agricultural products, and in particular to a safe and energy-saving agricultural product drying device. Background Technology

[0002] Agricultural product processing is a sunrise industry of the 21st century and is currently receiving high attention and support in China. Developing agricultural product processing is an important way to improve the overall efficiency of agriculture, enhance the international competitiveness of Chinese agriculture, and accelerate farmers' prosperity. As a crucial link in agricultural product processing, the drying process plays a vital role in the processing of various agricultural products, ensuring product quality, reducing losses, and providing high-quality raw materials for subsequent processes.

[0003] A vacuum rake dryer mainly consists of a stirring shaft, a cylinder, a transmission system, and a sealing device. The heat required for drying is primarily provided by the cylinder jacket. When the heating medium is introduced into the equipment, heat is indirectly heated to the material through the jacket. The moisture in the wet material vaporizes upon heating, and the vaporized moisture is promptly removed by the vacuum system. As the stirring shaft continuously rotates, the contact between the material and the heating surface constantly changes, ensuring uniform heating of the material and achieving the drying purpose.

[0004] The aforementioned dryers only store heat in the jacket of the cylinder, resulting in a relatively single heat source and outdated technology. Consequently, drying is the most energy-intensive step in agricultural product processing, leading to a significant waste of energy.

[0005] In addition, since most existing drying equipment uses manual feeding and discharging, it requires opening and closing the drying cylinder cover for operation. There is a problem that the rake teeth continue to rotate after the drying cylinder cover is opened, which may cause accidental injury. Summary of the Invention

[0006] The purpose of this invention is to provide a safe and energy-saving agricultural product drying equipment. It can not only integrate the stirring component and the hot liquid connecting pipe into a whole to form a three-dimensional drying heat source in the inner cylinder, but also improve the safety of opening and closing the side cover through the linkage between the safety drive component and the side cover component.

[0007] The objective of this invention is achieved through the following technical solution: a safe and energy-saving agricultural product drying equipment, comprising a main cylinder assembly, a stirring component, a hot liquid connecting pipe, a side cover assembly, and a safety drive assembly. The main cylinder assembly includes an outer cylinder and an inner cylinder. The stirring component includes a hollow main shaft and a hollow connecting pipe. The hot liquid connecting pipe includes an inlet pipe and an outlet pipe. The side cover assembly includes a side cover shaft and a side cover. The safety drive assembly includes a lower bevel gear and a rotating pulley. The outer cylinder is fixed to the outer main surface of the inner cylinder. A front cover is fixed to the upper part of the front end of the inner cylinder. A front rotating seat is connected to the middle of the front cover. One end of the hollow main shaft is screwed into the front rotating seat, and the other end is screwed into the rear middle of the inner cylinder. A main rake plate is connected between the outer ends of the pairs of hollow connecting pipes. The main rake plate and the pair of hollow connecting pipes are arranged and connected to the outside of the hollow main shaft. An inner partition plate is fixed inside the hollow main shaft, which can form a single-direction flow of the hollow main shaft, hollow connecting pipes, and main rake plate. The inlet pipe and outlet pipe are respectively connected to the two ends of the outer cylinder. The side ends of the inlet pipe and outlet pipe are connected to side connecting pipes. The other ends of the two sets of side connecting pipes are respectively screwed to the two ends of the hollow main shaft. The lower end of the side cover is screwed to the lower front end of the inner cylinder via the side cover shaft. The outside of the side cover is elastically screwed with a buckle. The outside of the front rotating seat is provided with a locking hole. After the side cover is closed, the buckle can be elastically locked in the locking hole. Both outer ends of the side cover shaft are fixed with drive linkages. The lower rear end of the inner cylinder is symmetrically screwed with driven linkages. A connecting rod is screwed between the lower end of each set of drive linkages and the lower end of the driven linkage. A rotatable drive bevel gear is also provided below the rear end of the inner cylinder. The lower bevel gear is screwed to the rear side of the driven linkage. The rotating pulley is screwed to the rear of the hollow main shaft. The lower bevel gear can only form an effective transmission connection between the drive bevel gear and the rotating pulley after the side cover is completely closed.

[0008] The process of using the technical solution of the present invention is as follows: With the side cover open, the side cover and the lower bevel gear are not meshed. At this time, the hollow main shaft, hollow connecting pipe, and main rake plate cannot rotate. In other words, when the side cover is open and the operator is adding material into the inner cylinder, the hollow connecting pipe and the main rake plate cannot be started to rotate, thus preventing accidental injury during operation. At this time, agricultural products to be dried can be safely added into the inner cavity of the inner cylinder. After the inner cylinder is filled with material, the side cover is closed. Under the action of the locking spring force, the head of the locking buckle will lock in the locking hole at the outer end of the front rotating seat, so that the side cover can form a convenient and safe closed and locked state. At the same time, opening the valves in the pipes connecting the inlet and outlet pipes allows the heat transfer oil used for drying to enter the cavity formed between the outer and inner cylinders through the inlet pipe. The oil then enters the hollow main shaft and the hollow connecting pipes and main rake plate through a set of side connecting pipes connected to the inlet pipe, and exits through the outlet pipe and a set of side connecting pipes connected to the outlet pipe. This achieves the circulation of the heat transfer oil outside the inner cylinder and in the hollow main shaft, hollow connecting pipes and main rake plate, thus making reasonable use of space and simultaneously inputting heat to the material inside the inner cylinder from both inside and outside. After the side cover is completely closed, the rotating structure composed of the drive rod, connecting rod and passive connecting rod can drive the lower bevel gear to mesh with the drive bevel gear. Through the automatic rotation of the drive bevel gear, the rotation of the rotating pulley and the hollow main shaft can be driven. Thus, the material is moved along the inner wall of the inner cylinder by the continuous stirring of the main rake plate. Combined with the heat from the outside of the inner cylinder and the main rake plate itself, the drying process is carried out efficiently and energy-savingly.

[0009] By adopting the above technical solution, the present invention has the following beneficial effects: (1) The present invention sets the hollow connecting pipe and the main rake plate connected to the hollow main shaft into a unique cavity mechanism with a single flow direction, and connects the inlet and outlet pipes on both sides of the hollow main shaft with the side connecting pipes, so that the heat transfer oil used for drying and heating can enter the cavity formed by the outer cylinder and the inner cylinder, and at the same time fill the hollow main shaft and each set of hollow connecting pipes and the main rake plate, thereby forming a three-dimensional heat source, which can dry the material in the inner cylinder more efficiently and energy-savingly. (2) The present invention also adds a safety mechanism to prevent accidental injury at the openable and closable side cover. By fixing drive rods at both ends of the side cover shaft that drives the side cover to rotate open and close, and forming a rotation push mechanism between the drive rod and the passive rod screwed to the lower rear end of the inner cylinder through a connecting rod, the lower bevel gear can mesh with the drive bevel gear after the side cover is closed. This ensures that the hollow main shaft can be driven to rotate by the rotation of the drive bevel gear after the operator is isolated from the inner cavity of the inner cylinder, thereby improving the safety of the operation process.

[0013] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] like Figures 1-11 As shown, a safe and energy-saving agricultural product drying equipment is provided. In the main cylinder assembly 1, the outer cylinder 102 is sealed and fixed to the outer main surface of the inner cylinder 103. A front cover 107 is fixed to the upper part of the front end of the inner cylinder 103. A front rotating seat 108 is connected to the middle part of the front cover 107. One end of the hollow main shaft 201 is screwed into the front rotating seat 108, and the other end is screwed into the rear middle part of the inner cylinder 103. A main rake plate 203 is connected between the outer ends of a pair of hollow connecting pipes 202. The main rake plate 203 and the pair of hollow connecting pipes 202 are arranged and connected to the outside of the hollow main shaft 201. An inner isolation plate 204 is fixed inside the hollow main shaft 201, which can form a completely non-short-circuited unidirectional flow direction of the hollow main shaft 201, the hollow connecting pipes 202, and the main rake plate 203. The inlet pipe 301 and the outlet pipe 302 are respectively connected to the two ends of the outer cylinder 102 and communicate with the cavity formed by the outer cylinder 102 and the inner cylinder 103. The side ends of the inlet pipe 301 and the outlet pipe 302 are connected to the side connecting pipes 303. The other ends of the two sets of side connecting pipes 303 are respectively sealed and screwed to the two ends of the hollow main shaft 201. The lower end of the side cover 403 is screwed to the lower front end of the inner cylinder 103 via the side cover shaft 402. The side cover 403 is elastically screwed with a latch 408. The front rotating seat 108 has a locking hole 410 on its outer side. After the side cover 403 is closed to form a seal with the front cover 107, the latch 408 can be elastically locked in the locking hole 410. Both outer ends of the side cover shaft 402 are fixed with drive connecting rods 501. The lower rear end of the inner cylinder 103 is symmetrically screwed with passive connecting rods 506. A connecting rod 503 is screwed between the lower end of each set of drive connecting rods 501 and the lower end of passive connecting rods 506. A rotatable drive bevel gear 513 is also provided below the rear end of the inner cylinder 103. The lower bevel gear 510 is screwed on the rear side of the passive connecting rod 506. The rotating pulley 518 is screwed on the rear of the hollow main shaft 201. Only after the side cover 403 is completely closed can the lower bevel gear 510 form an effective transmission connection between the drive bevel gear 513 and the rotating pulley 518. With the side cover 403 open, agricultural products to be dried can be added into the inner cavity of the inner cylinder 103. Furthermore, with the side cover 403 open, the side cover 403 and the lower bevel gear 510 are in a non-meshing position. At this time, the hollow main shaft 201, the hollow connecting pipe 202, and the main rake plate 203 cannot rotate. In other words, when the side cover 403 is open and the operator is adding material into the inner cylinder 103, the hollow connecting pipe 202 and the main rake plate 203 will never be able to start rotating, thus preventing accidental injury during operation. After the inner cavity of the inner cylinder 103 is filled with material, the side cover 403 is closed, and under the action of the rotational elasticity of the latch 408, the head end of the latch 408 will be locked in the lock hole 410 at the outer end of the front rotating seat 108, so that the side cover 403 can form a convenient and safe closed and locked state. At the same time, opening the valves in the pipes connecting the inlet pipe 301 and the outlet pipe 302 allows the heat transfer oil used for drying to enter the cavity formed between the outer cylinder 102 and the inner cylinder 103 through the inlet pipe 301. The oil then enters the hollow main shaft 201 and the hollow connecting pipes 202 and the main rake plate 203 through a set of side connecting pipes 303 connected to the inlet pipe 301. Finally, the oil exits through the outlet pipe 302 and the set of side connecting pipes 303 connected to the outlet pipe 302. This allows the heat transfer oil to circulate outside the inner cylinder 103 and within the hollow main shaft 201, hollow connecting pipes 202, and main rake plate 203, thus making efficient use of space and simultaneously inputting heat into the material inside the inner cylinder 103. After the side cover 403 is completely closed, the rotating structure composed of the drive rod 501, connecting rod 503 and passive connecting rod 506 can drive the lower bevel gear 510 to mesh with the drive bevel gear 513. Through the automatic rotation of the drive bevel gear 513, the rotation pulley 518 and the hollow main shaft 201 can be driven to rotate. Thus, the material is moved along the inner wall of the inner cylinder 103 by the continuous stirring of the main rake plate 203. Combined with the heat of the outside of the inner cylinder 103 and the main rake plate 203 itself, the drying process is carried out efficiently and energy-savingly.

[0016] The specific structures of the main cylinder assembly 1, the stirring component 2, and the hydrothermal connection pipe 3 are as follows: Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the outer bottom surface of the outer cylinder 102 is fixedly connected to the top of the base frame 101. The vacuum suction tube 104 passes through the outer cylinder 102 and is fixed separately to the outer wall of the inner cylinder 103, and communicates only with the inner cavity of the inner cylinder 103. The rear end of the inner cylinder 103 is fixedly connected to a rear cover 105, and the middle part of the rear cover 105 is connected to a rear rotating seat 106. The inner sealing sleeves 205 are fixedly connected to the inside of both ends of the hollow spindle 201, and the other end of the side connecting tube 303 is rotatably sealed inside the inner sealing sleeves 205. The device is fixedly connected to the mounting surface via the base frame 101. The purpose of setting the vacuum suction pipe 104 is that the external vacuum suction equipment can communicate with the inner cavity of the inner cylinder 103 through the vacuum suction pipe 104, so that a high vacuum degree can be formed inside the inner cylinder 103 during the drying process, which is conducive to the rapid discharge of the moisture formed by the evaporation of the dried material, thus achieving the purpose of faster drying.

[0017] The specific structures of the side cover assembly 4 and the safety drive assembly 5 are as follows: Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the side cover screw base 401 is fixedly connected to the bottom front end of the inner cylinder 103, the bottom center of the side cover 403 is fixedly connected to the connecting arm 404, the side cover shaft 402 is rotatably connected to the side cover screw base 401, and the connecting arm 404 is inserted and fixed in the side cover shaft 402. The handrail 405 is fixedly connected to the outside of the side cover 403, the latch seat 407 is connected to one end of the main body of the handrail 405, and the latch shaft 409 is fixedly connected to the middle of the outer end of the latch 408. The latch shaft 409 is rotatably connected in the latch seat 407. A spring plate seat 411 is also fixedly connected to the outside of the side cover 403. One end of the locking spring plate 412 is fixed to the side of the spring plate seat 411, and the other end is fixed to the side of the tail end of the latch 408. A lock hole 410 is provided on one side of the main body of the front rotating seat 108. Under the action of the spring force of the locking spring 412, after the side cover 403 is closed, the head end of the latch 408 can be locked in the lock hole 410. An inner sealing gasket 406 is also fixedly installed on the upper inner part of the side cover 403, which can form a completely sealed effect after the side cover 403 is attached to the outside of the front cover 107. Furthermore, the head end of the latch 408 is an arc structure concentric with the latch shaft 409, and the lock hole 410 is an arc groove centered on the latch shaft 409. In other words, during the rotation of the latch 408 around the latch shaft 409, the arc structure at the head end of the latch 408 is always concentric with the lock hole 410, making it easier to smoothly and accurately insert the arc structure at the head end of the latch 408 into the lock hole 410. The drive shaft 502 is fixed to the lower end of the two sets of drive rods 501, the driven shaft 507 is fixed to the lower end of the two sets of driven rods 506, one end of the connecting rod 503 is rotatably connected to the outer end of the drive shaft 502, and the other end is rotatably connected to the outer end of the driven shaft 507. By adding the drive shaft 502 between the two sets of drive rods 501 and the driven shaft 507 between the two sets of driven rods 506, the stability of the screw-connected structure composed of the drive rods 501, the driven rods 506 and the connecting rod 503 can be improved. The lower end of the rear cover 105 is fixedly connected to the rear base 504, the passive coupling 505 is rotatably connected in the rear base 504, and the upper end of the passive connecting rod 506 is inserted and fixed in the passive coupling 505. Two sets of passive connecting rods 506 are fixedly connected to a transmission seat 508 on the outside. A transmission shaft 509 is rotatably connected in the transmission seat 508. A lower bevel gear 510 is inserted and fixed at the lower end of the transmission shaft 509. An upper bevel gear 511 is inserted and fixed at the upper end of the transmission shaft 509. A drive motor 512 is mounted and fixed on one side of the top of the base frame 101, and a drive bevel gear 513 is inserted and fixed in the rotating shaft of the drive motor 512. The switching seat 515 is fixedly connected to the top of the rear end of the base frame 101, the switching shaft 516 is rotatably connected in the switching seat 515, and the switching bevel gear 514 and the switching pulley 517 are both inserted and fixed in the switching shaft 516. A connecting belt 519 is fitted between the rotating pulley 518 and the switching pulley 517. Only when the side cover 403 is completely closed can the lower bevel gear 510 be engaged with the drive bevel gear 513 through the rotating structure composed of the drive link 501, the passive link 506 and the connecting rod 503. This ensures that the drive bevel gear 513 can drive the rotation of the rotating pulley 518 through an effective transmission structure only after the side cover 403 is completely closed.

[0018] By holding the handrail 405 and pressing the tail end of the latch 408, the side cover 403 can be opened by rotating the side cover 403 and then closed until the head end of the latch 408 is locked into the lock hole 410. When the side cover 403 opens and closes around the side cover shaft 402, the transmission mechanism can drive the passive connecting rod 506 to rotate around the passive connecting shaft 505, so that after the side cover 403 is closed, the lower bevel gear 510 can move to the position of meshing with the drive bevel gear 513. At the same time, the upper bevel gear 511 moves to the position where it meshes with the switching bevel gear 514; In other words, only after materials are added to the inner cylinder 103 and the side cover 403 is safely closed, the lower bevel gear 510 can be rotated by starting the drive motor 512 to drive the rotation of the drive bevel gear 513. After the lower bevel gear 510 rotates, it drives the upper bevel gear 511 to rotate coaxially through the transmission shaft 509. The upper bevel gear 511 and the switching bevel gear 514 form a transmission, which can drive the rotation of the switching pulley 517. The switching pulley 517 drives the rotation of the rotating pulley 518 through the connecting belt 519, so that the hollow main shaft 201 rotates. The hollow main shaft 201 drives the hollow connecting pipe 202 and the main rake plate 203 to rotate, thus performing a stirring action under heating. Since the inner surface of the inner cylinder 103 is a relatively smooth mirror surface, and the inner cylinder 103 itself is a structure that is slightly inclined towards the side cover 403, after the side cover 403 is opened to a position that does not obstruct the inner cylinder 103, the dried material can be quickly taken out using tools. Furthermore, there is a sufficient gap between the transmission shaft 509 and the outside of the rear cover 105 so that the upper bevel gear 511, which flips upward after the side cover 403 is fully opened, will not touch or interfere with the rear cover 105.

[0019] The specific structure of the passive rake component 6 is as follows: Figure 10 and Figure 11 As shown, it can be used in conjunction with the stirring action of the main rake plate 203 to synchronously turn the material being dried in the inner cylinder 103, thereby improving the drying efficiency to a certain extent. The guide rod slide 602 is fixedly connected between two sets of non-connected hollow connecting pipes 202 located on the same straight path. The guide rod 603 is slidably connected in the guide rod slide 602. An inner sliding slope 601 is fixedly connected to the upper part of the inner cavity of the inner cylinder 103. A sliding protrusion 604 is fixedly connected to the outer end of the guide rod 603. The position of the sliding protrusion 604 is directly opposite to the position of the inner sliding slope 601. A top spring 605 is also sleeved and fixed in the guide rod 603. One end of the top spring 605 is fixed to one side of the sliding protrusion 604, and the other end is fixed to one side of the guide rod slide 602. Because the passive rake plate 610 has an opening in the middle, it can avoid interference with the inner sliding slope 601; Furthermore, under the action of the top spring 605, the sliding protrusion 604 is always in a position tangent to the inner sliding slope 601 or the inner cavity surface of the inner cylinder 103; A swing seat 606 is fixedly connected between two sets of hollow connecting pipes 202 located on the same straight path but not connected to each other. The middle part of the swing rod 607 is rotatably connected in the swing seat 606. The inner end of the guide rod 603 is fixedly connected to the swing slide column 609. The inner end of the swing rod 607 is fixedly connected to the swing slide 608. The outer end is fixedly connected to the passive rake plate 610. The swing slide column 609 is slidably connected in the long groove of the swing slide 608. When the hollow main shaft 201 rotates, under the action of the top spring 605, it will drive the sliding protrusion 604 to move tangentially along the path formed by the inner sliding slope 601 and the inner surface of the inner cylinder 103. After the sliding protrusion 604 moves from being tangential to the inner surface of the inner cylinder 103 to being tangential to the inner sliding slope 601, it will drive the guide rod 603 to move within a certain range. Thus, through the sliding cooperation formed by the swinging sliding column 609 and the swinging sliding seat 608, the swinging rod 607 and the passive rake plate 610 will swing with the swinging rotating seat 606 as the reference. After the passive rake plate 610 swings, the material within its touch range can be turned over. Combined with the stirring action of the main rake plate 203, the uniformity of the material movement in the inner cylinder 103 can be improved, thereby improving the drying efficiency.

[0020] Preferably, the number of passive rake components 6 connected between the stirring member 2 and the inner cavity of the inner cylinder 103 is greater than or equal to 1, and the number can be increased according to the actual situation. When it is necessary to increase the number of passive rake components 6, it is only necessary to fix the guide rod slide 602 in the gap between two sets of hollow connecting pipes 202 that are not connected on the same straight path, and fix the swinging seat 606 in the gap between two sets of hollow connecting pipes 202 that are not connected on the same straight path that are directly opposite to the guide rod slide 602. This allows other mechanisms to be connected between the horizontally opposite guide rod slide 602 and swinging seat 606, and the inner sliding slope 601 is fixed on the inner cavity surface of the inner cylinder 103 at the same time.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
