Description

Technical Field

[0001] This invention relates to the field of agricultural product conveying equipment technology, specifically to an anti-blocking device for the processing and transportation of natural spices. Background Technology

[0002] Natural spices refer to raw materials made from the aromatic parts of plants and animals through simple processing, or aromatic substances separated from natural raw materials using physical methods. They are widely used in food, daily chemicals, medicine and other fields. Many kinds of spices used in daily food include cinnamon, star anise, bay leaves, Sichuan pepper, cardamom and so on. These spices need to go through processes such as screening and sorting, washing and removing impurities, drying and dehydrating, and packaging and sealing. The transportation equipment is needed for closed transmission between each process.

[0003] Because spices need to meet food-grade hygiene requirements, they must be transported through sealed pipes. To prevent spices from getting stuck at bends in the pipes, curved bends are installed at these locations. While the bends can solve some of the blockages, the spices will continuously impact the inner wall of the bends as they fall. Some spices contain oils, and some of these oils will stick to the inner wall of the bends when they collide with them. Over time, this can easily cause oily spices to stick and block the bends. Summary of the Invention

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an anti-blocking device for the processing and transportation of natural spices, which has the following beneficial effects: 1. By setting up a scraping component and a bend, the bend consists of two bends, a first bend and a second bend, with an included angle of 45 degrees, forming a 90-degree bend. Compared to an arc-shaped structure, this is easier to manufacture, and the cross-section at the impact point is a regular circle, which makes better use of the scraping component. The scraping component uses a first motor to drive the worm and worm wheel to rotate, and the worm wheel drives the movable scraper to scrape and clean the inner walls of the first and second bends that are contaminated with grease. This avoids the problem of a large amount of grease sticking together and causing blockage in the bend, making the pipe suitable for transporting spices with high grease content.

[0016] 2. By setting up a spiral conveying pipe and a forward / reverse drive component, the spiral conveying pipe is mainly composed of an outer cylinder and a shaftless spiral blade. The way the two work together is different from the existing spiral conveying equipment. The shaftless spiral blade uses the support rings at both ends to rotate with the outer cylinder, eliminating the need for a central drive shaft and avoiding the risk of some fibrous fragrances getting entangled. The forward / reverse drive component can drive the outer cylinder and the shaftless spiral blade to rotate simultaneously in opposite directions. When the outer cylinder and the shaftless spiral blade rotate in opposite directions, a high-frequency relative motion is formed between them. This can improve the efficiency of the shaftless spiral blade in pushing the fragrance forward without increasing the rotation speed. In addition, when the outer cylinder rotates in the reverse direction, it will scrape off the fragrances adhering to the cylinder wall, ensuring that the fragrances are fully pushed, avoiding local accumulation, improving the continuity of conveying, and preventing some oily fragrances from sticking to the inside of the outer cylinder.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1 Please see Figures 1 to 4 A clog prevention device for processing and transporting natural spices includes a bent pipe body 1 and a spiral conveying pipe 4. The bent pipe body 1 is provided with a scraping component 2 that fits against the inner pipe wall. The bent pipe body 1 includes a first bent pipe 101 and a second bent pipe 102 with a bending angle of 45 degrees. The scraping component 2 includes a housing 201 disposed between the first bend 101 and the second bend 102. A hollow worm wheel 202 is rotatably disposed inside the housing 201. The inner wall of the worm wheel 202 is flush with the inner walls of the first bend 101 and the second bend 102. A worm 204 is engaged with the side of the worm wheel 202. A first motor 203 disposed on one side of the housing 201 is connected to the end face of the worm 204. A movable scraper 205 is disposed on the inner wall of the worm wheel 202 and fits against the inner walls of the first bend 101 and the second bend 102. By setting up a scraping component 2 and a bent pipe body 1, the bent pipe body 1 is composed of two first bent pipes 101 and second bent pipes 102 with an included angle of 45 degrees, which together form a 90-degree bent pipe body 1. Compared with the arc structure, it is easier to produce, and the cross section of its impact-bearing inclined plate 307 is a regular circle, which makes better use of the work of the scraping component 2. The scraping component 2 uses the first motor 203 to drive the worm 204 and worm wheel 202 to rotate. The worm wheel 202 drives the movable scraper 205 to scrape and clean the inner walls of the first bent pipes 101 and second bent pipes 102 that are contaminated with grease, avoiding the problem of a large amount of grease sticking together and causing the bent pipe body 1 to be blocked. This allows the pipe to be used for the transportation of some spices with a large amount of grease. It should be further explained that the inner wall of the worm gear 202 is flush with the inner walls of the first bend 101 and the second bend 102, so the fragrance can flow smoothly during transportation without being affected by the worm gear 202. At the same time, food-grade, odorless, and low-flow lubricating oil is preferred between the worm gear 202 and the outer shell 201, and the lubricating oil is added in small amounts and multiple times to reduce the impact of the lubricating oil on the fragrance transportation.

[0021] like Figure 4 As shown, the movable scraper 205 includes a rubber scraper 2051 and a metal spring sheet 2052. The rubber scraper 2051 is wrapped around the outside of the metal spring sheet 2052 and directly contacts the inner wall of the first bend 101 and the second bend 102. The metal spring sheet 2052 applies a spring force to the rubber scraper 2051 in the direction of the inner wall of the first bend 101 and the second bend 102. By setting a rubber scraper 2051 and a metal spring 2052, the rubber scraper 2051 is made of food-grade, highly wear-resistant, oil-resistant, and corrosion-resistant material. It can stably scrape off the grease from the inner walls of the first bend 101 and the second bend 102, and can withstand the erosion of chemicals such as oils, esters, alcohols, and acids in the fragrance, ensuring food safety during the fragrance transportation process. The metal spring 2052 is located inside the rubber scraper 2051 and does not come into contact with the fragrance. Its purpose is to use its own elasticity to apply pressure to the rubber scraper 2051, so that the rubber scraper 2051 fits tightly against the inner walls of the first bend 101 and the second bend 102, and avoids the deformation problem of the rubber scraper 2051 after long-term use.

[0022] like Figure 3 As shown, a fixed scraper 206 that fits against the inner wall of the worm gear 202 is fixedly provided on the inner wall of the outer casing 201; By setting a fixed scraper 206, and since the movable scraper 205 is fixed on the inner wall of the worm gear 202, the movable scraper 205 and the worm gear 202 are relatively stationary. The fixed scraper 206 is set on the inner wall of the outer shell 201. When the worm gear 202 rotates, the fixed scraper 206 can scrape off the grease and fragrance adhering to the inner wall of the worm gear 202, achieving a comprehensive scraping effect. In addition, it should be noted that, in order to avoid excessive compression during fragrance delivery, the pipe is mostly not full. Therefore, the fragrance mainly flows at the bottom, while the fixed scraper 206 is set at the upper part where the fragrance is not easily accessible. Therefore, the movable scraper 205 mainly focuses on scraping the fragrance flow part without interfering with the fixed scraper 206.

[0023] Example 2 like Figures 5 to 15 As shown, one end of the spiral conveying pipe 4 is provided with a forward and reverse rotation drive component 7, and both ends of the spiral conveying pipe 4 are respectively provided with rotating supports 3 connected to the forward and reverse rotation drive component 7 and the second bend pipe 102. The spiral conveying pipe 4 includes an outer cylinder 401 connected to the rotating supports 3. The outer cylinder 401 is provided with a first discharge port 9 at the end near the forward and reverse rotation drive component 7. A shaftless spiral blade 404 is rotatably provided inside the outer cylinder 401. Support rings 406 are provided at both ends of the shaftless spiral blade 404. Rotating grooves 405 that rotatably cooperate with the support rings 406 are provided at both ends of the outer cylinder 401. An end sealing plate 10 that rotatably cooperates with the inner wall of the outer cylinder 401 is provided at the end of the shaftless spiral blade 404 near the forward and reverse rotation drive component 7. The forward and reverse rotation drive component 7 is connected to the outer cylinder 401 and the shaftless spiral blade 404 in a transmission connection. This embodiment uses a spiral conveying pipe 4 and a forward / reverse drive component 7. The spiral conveying pipe 4 mainly consists of an outer cylinder 401 and a shaftless spiral blade 404. The way they work together is different from existing spiral conveying equipment. The shaftless spiral blade 404 uses support rings 406 at both ends to rotate with the outer cylinder 401, eliminating the need for a central drive shaft and avoiding the risk of some fibrous fragrances getting tangled. The forward / reverse drive component 7 can simultaneously drive the outer cylinder 401 and the shaftless spiral blade 404 to rotate in opposite directions. When the outer cylinder 401 and the shaftless spiral blade 404 rotate in opposite directions, they form a high-frequency relative motion, which can improve the efficiency of the shaftless spiral blade 404 in pushing the fragrance forward without increasing the rotation speed. In addition, when the outer cylinder 401 rotates in the opposite direction, it will scrape off the fragrances attached to the cylinder wall, ensuring that the fragrances are fully pushed, avoiding local accumulation, improving the continuity of conveying, and preventing some oily fragrances from sticking to the inside of the outer cylinder 401. Furthermore, it should be noted that in some production processes, it is necessary to transport mixed fragrances made from various spices in a specific ratio. The aforementioned reverse-rotation combination of the shaftless spiral blade 404 and the outer cylinder 401 not only achieves fragrance transport but also generates bidirectional shear force and eddy current effect. This causes the fragrances to undergo more complex tumbling and interlacing motions during transport, rather than a single-direction translation. This is equivalent to embedding a dynamic mixing function in the transport process, allowing fragrance particles with different properties to contact and mix more evenly, reducing component deviations in subsequent processing, and replacing some low-requirement mixing tasks.

[0024] like Figure 7 As shown, the end face of the shaftless spiral blade 404 is provided with a insertion hole 407. The insertion hole 407 is provided with a insertion pin 408 that connects to the adjacent shaftless spiral blade 404. By setting the insertion hole 407 and the support ring 406, the support ring 406 is located at both ends of the shaftless spiral blade 404 and cooperates with the rotation groove 405 at both ends of the outer cylinder 401. On the one hand, it can support the shaftless spiral blade 404 and make it rotate stably in the outer cylinder 401. On the other hand, by using the cooperation between the support ring 406 and the rotation groove 405, it can prevent the shaftless spiral blade 404 from moving radially. In this way, there is no need to set the bracket and bearing in the outer cylinder 401, avoiding the bracket from obstructing the fragrance delivery. The insertion hole 407 can be connected to the insertion pin 408, so that after the two sets of spiral conveying pipes 4 are spliced, the shaftless spiral blades 404 on their inner walls can be connected by the insertion pin 408 and can be rotated. In this way, multiple spiral conveying pipes 4 can be conveniently assembled in series, increasing the flexibility of equipment use.

[0025] like Figure 5 As shown, the rotating support 3 includes a first fixed frame 301, a fixed seat 302 is provided under the first fixed frame 301, a rotating seat 303 is rotatably fitted inside the fixed seat 302, the rotating seat 303 is connected to the outer cylinder 401, a steel ball 304 is slidably provided between the rotating seat 303 and the fixed seat 302, and a maintenance hole 305 corresponding to the movement path of the steel ball 304 is provided on the fixed seat 302; By setting a rotating support 3, which includes a fixed seat 302 and a rotating seat 303, the two are rotated together by steel balls 304. The fixed seat 302 does not rotate and is used to connect with the bent tube body 1 and the forward and reverse drive component 7. The rotating seat 303 can rotate freely and is used to connect with the outer cylinder 401. The rotating seat 303 and the fixed seat 302 are hollow inside, so that spices can pass through freely and the outer cylinder 401 can rotate. With the power of the forward and reverse drive component 7, the outer cylinder 401 and the shaftless spiral blade 404 can achieve the effect of reversing.

[0026] like Figure 14As shown, the forward and reverse drive component 7 includes a second motor 701 connected to the fixed base 302 and a fixed planetary carrier 703. The end face of the second motor 701 is provided with a rotating shaft 702. The end face of the rotating shaft 702 is provided with a sun gear 704 connected to the shaftless spiral blade 404. The side of the sun gear 704 meshes with a planetary gear 705 provided on the fixed planetary carrier 703. The outer side of the planetary gear 705 meshes with an internal gear ring 706 fixedly connected to the outer cylinder 401. By setting a fixed planetary carrier 703 and planetary gears 705, the fixed planetary carrier 703 does not rotate due to its connection with the fixed base 302. Correspondingly, the planetary gears 705 connected to it only rotate on their own axis and do not revolve around the sun. When the second motor 701 drives the rotating shaft 702 to rotate, the rotating shaft 702 will directly drive the shaftless spiral blade 404 to rotate through the sun gear 704, so that the shaftless spiral blade 404 can push the spices to move. At the same time, the sun gear 704 will drive the internal gear ring to rotate in the opposite direction through the planetary gears 705 meshing with it. The internal gear ring will drive the outer cylinder 401 fixedly connected to it to rotate, so that the shaftless spiral blade 404 and the outer cylinder 401 rotate simultaneously and in opposite directions. This improves the relative motion frequency between the shaftless spiral blade 404 and the outer cylinder 401 without increasing the rotation speed, making its conveying efficiency higher and preventing the sticking of high-oil content.

[0027] like Figure 7 and Figure 8 As shown, an oil groove 409 is provided on the outer side of the support ring 406, and a lubricating oil injection hole 8 is provided on the outer cylinder 401 corresponding to the position of the oil groove 409. By setting the oil groove 409, which is located on the support ring 406, lubricating oil can be injected into it through the lubricating oil injection hole 8. The lubricating oil reduces the friction between the support ring 406 and the rotating groove 405, making the rotation of the support ring 406 smoother. It should be noted that the lubricating oil is preferably food-grade, odorless, and low-flow lubricating oil, and the lubricating oil is added in small amounts multiple times to reduce the impact of the lubricating oil on the fragrance delivery process.

[0028] like Figure 5As shown, a fixed ring 306 is provided inside the rotating base 303. Multiple inclined plates 307 extending into the second curved pipe 102 are arranged in a circular array within the fixed ring 306. By setting the fixed ring 306 and the inclined plates 307, the fixed ring 306, located inside the rotating base 303, can rotate with the rotating base 303, while the inclined plates 307, located inside the fixed ring 306, rotate synchronously with the fixed ring 306. When the outer cylinder 401 drives the rotating base 303 to rotate, the fixed ring 306 and the inclined plates 307 move together. When the rotor rotates, the inclined plate 307 will push the fragrance into the outer cylinder 401, preventing fragrance residue from remaining in the second bend 102 and the rotating support 3, which are inaccessible to the shaftless spiral blade 404. Alternatively, a spiral blade can be added inside the fixed ring 306 to replace the inclined plate 307. It should be noted that since the rotating seat 303 rotates with the outer cylinder 401, and the rotation direction of the outer cylinder 401 is opposite to that of the shaftless spiral blade 404, the spiral direction of the added spiral blade should be opposite to that of the shaftless spiral blade 404.

[0029] like Figure 6 and Figure 9 As shown, a wear-resistant ring 403 is provided on the outer side of the outer cylinder 401. A support 5 for supporting the outer cylinder 401 is rolled on the side of the wear-resistant ring 403. The support 5 includes a second fixed frame 501. Two positioning rollers 502 that fit against the upper part of the wear-resistant ring 403 are provided on the inner side of the second fixed frame 501. Opening and closing frames 503 are hinged on both sides of the lower part of the second fixed frame 501. Support rollers 504 that fit against the lower part of the wear-resistant ring 403 are provided in the opening and closing frame 503. A threaded locking assembly 505 is hinged to the lower part of one side of the opening and closing frame 503. An opening groove 507 that fits against the threaded locking assembly 505 is opened on the lower part of the other side of the opening and closing frame 503. A groove 402 that fits against the support rollers 504 and the positioning rollers 502 is opened on the wear-resistant ring 403. By setting up the support bracket 5, the support bracket 5 can support the outer cylinder 401 through the rolling engagement with the wear-resistant ring 403, so that the outer cylinder 401 can maintain a stable horizontal state when laid over a long distance, without affecting the rotation of the outer cylinder 401. The groove 402 can be engaged with the support roller 504 and the positioning roller 502 to prevent the outer cylinder 401 from moving radially. In addition, it should be noted that the support roller 504 can be opened by using the hinged opening and closing frame 503 to separate it from the wear-resistant ring 403, which facilitates the disassembly and maintenance of the outer cylinder 401. The threaded locking component can lock the two opening and closing frames 503 to achieve the purpose of long-term stable support.

[0030] like Figure 11As shown, the threaded locking assembly 505 includes a hinge seat 5051 connected to the opening and closing frame 503. A rotating rod 5052 is rotatably provided inside the hinge seat 5051. The rotating rod 5052 is provided with a fastening thread 5053 at the position corresponding to the opening slot 507. A handwheel 5054 is provided on the rotating rod 5052 and is threadedly connected to the fastening thread 5053. The handwheel 5054 is attached to the outside of the opening slot 507. A support 508 is provided on the outside of the opening and closing frame 503 and is attached to the lower part of the handwheel 5054. A slot 5055 is provided on the handwheel 5054. A backstop assembly 506 is provided on the opening and closing frame 503 to prevent the handwheel 5054 from reversing through the slot 5055. By setting up a rotating rod 5052 and a handwheel 5054, when it is necessary to close the two opening and closing frames 503, the rotating rod 5052 is rotated upward by the handwheel 5054, so that the rotating rod 5052 moves into the opening slot 507. Then, the handwheel 5054 is rotated. The handwheel 5054 is connected with the fastening thread 5053 and moves towards the opening and closing frame 503. Since the size of the handwheel 5054 is larger than the opening slot 507, it cannot pass through the opening slot 507, and thus it will squeeze the opening and closing frame 503, so that the opening and closing frame 503 is subjected to downward pressure, achieving the purpose of fixing. It should be noted that when the handwheel 5054 is rotated to the fastening position, it will be supported by the support platform 508. The support platform 508 can prevent the handwheel 5054 and the rotating rod 5052 from falling off along the opening slot 507.

[0031] like Figure 12 As shown, the anti-reverse assembly 506 includes a sliding sleeve 5061 disposed on the opening and closing frame 503, a sliding rod 5063 slidably disposed inside the sliding sleeve 5061, an inclined locking block 5065 disposed below the sliding rod 5063 and fitting into the locking groove 5055, a downward force-applying spring 5064 disposed between the sliding rod 5063 and the sliding sleeve 5061, a crossbar 5066 disposed at the top of the sliding rod 5063, and a sliding groove 5062 disposed on the front side of the sliding sleeve 5061 and slidingly engaging with the crossbar 5066 perpendicularly; By setting up the inclined locking block 5065 and the spring 5064, when the handwheel 5054 rotates in the tightening direction, the slot 5055 it opens will squeeze the inclined surface of the inclined locking block 5065, so that the inclined locking block 5065 is pushed upward to avoid it. When the handwheel 5054 rotates to the tightening position, the inclined locking block 5065 will be engaged in the slot 5055 under the push of the spring 5064, so that the handwheel 5054 cannot be reversed, thus avoiding the problem of the handwheel 5054 becoming loose. When it is necessary to disassemble the handwheel 5054, the slide bar 5063 is lifted upward by the crossbar 5066, so that the slide bar 5063 drives the inclined locking block 5065 to separate from the slot 5055. At this time, the handwheel 5054 is unlocked and can be reversed to be released.

[0032] like Figure 1 and Figure 15As shown, a material collection cover 6 is fitted on the outer cylinder 401 at the position corresponding to the first discharge port 9. The material collection cover 6 includes two arc-shaped cover plates 601 covering the side of the outer cylinder 401. The two arc-shaped cover plates 601 are connected by bolts, and a sealing slip ring 603 is provided between the two and the outer cylinder 401. A connecting frame 602 fixedly connected to the adjacent rotating support 3 is provided on the side of the arc-shaped cover plate 601. A second discharge port 604 is provided under the arc-shaped cover plate 601. By setting an arc-shaped cover plate 601 and a sealing slip ring 603, the arc-shaped cover plate 601 can be placed on the outer cylinder 401 at the position corresponding to the first discharge port 9, so that when the outer cylinder 401 rotates, the fragrance thrown out by the first discharge port 9 can be concentrated by the arc-shaped cover plate 601 to prevent the fragrance from falling. The sealing slip ring 603 can close the gap between the arc-shaped cover plate 601 and the outer cylinder 401 to further prevent small fragrance particles from falling.

[0033] It should also be noted that all the structures mentioned above that come into direct contact with the spices meet food-grade requirements.

[0034] Working principle: When the fragrance passes through the bent tube 1, it impacts the outer side of the inner wall of the first bent tube 101 and the second bent tube 102. As a result, the grease generated by the impact will accumulate at this location. During cleaning, the first motor 203 drives the worm wheel 202 to rotate through the worm 204. The worm wheel 202 then drives the movable scraper 205 to scrape off the impacted locations of the first bent tube 101 and the second bent tube 102. The scraped-off grease is discharged with the fragrance, thus achieving the purpose of cleaning the grease inside the bent tube 1. The bent tube 1 uses the first bent tube 101 and the second bent tube 102 to form a non-circular arc bend, which facilitates the contact of the movable scraper 205 with its inner wall.

[0035] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
