Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology for the food industry, and more specifically, to a soybean raw material conveying device for soy sauce production. Background Technology

[0002] Soybean raw material conveying equipment for soy sauce production is a specialized device for the automated transportation of soybean raw materials. It typically consists of a conveyor belt, elevator, sorting mechanism, or pneumatic conveying system. It is responsible for efficiently and hygienically transporting soybeans from the storage area to pre-processing stages such as washing, soaking, or cooking, ensuring a continuous and stable production process. This equipment must meet food-grade hygiene standards to prevent contamination and can integrate functions such as weighing and impurity removal to improve the automation level and raw material processing efficiency of soy sauce production.

[0003] In soy sauce production, selected soybeans are cooked in steaming containers and then transported to the next stage via conveyor belt. During transport, the conveyor belt is equipped with a stirring device to evenly agitate the soybeans, preventing clumping and promoting cooling. This step ensures that the soybeans remain loose before subsequent fermentation, which is beneficial for the uniform action of microorganisms, thereby improving the flavor and quality of the soy sauce. The entire process is efficient, hygienic, and meets the automation requirements of modern soy sauce production.

[0004] During the transportation of cooked soybeans, the soybeans on the upper layer of the conveyor belt dissipate heat faster, making them prone to clumping. Soybeans in contact with the conveyor belt dissipate heat more slowly. Therefore, simply installing a stirring device on the conveyor belt can turn the soybeans, but it is not easy to separate clumped soybeans. Separating them through a manhole is also quite troublesome. If a crushing device is installed, the cooked soybeans are relatively soft, and using a crushing device may damage the soybean particles, affecting subsequent production. Summary of the Invention

[0005] This invention provides a soybean raw material conveying device for soy sauce production, which solves the problem in related technologies where, during the transportation of cooked soybeans, soybeans on the upper layer of the conveyor belt dissipate heat quickly, making them prone to clumping, while soybeans in contact with the conveyor belt dissipate heat more slowly. Therefore, while a stirring device can be installed on the conveyor belt to turn the soybeans, it is difficult to separate clumped soybeans. Separating them through a manhole is also troublesome. If a crushing device is installed, the cooked soybeans are soft, and using a crushing device may damage the soybean particles, affecting subsequent production processes.

[0006] This invention provides a soybean raw material conveying device for soy sauce production, including a conveyor belt with multiple support columns and a heat dissipation device on the side of the conveyor belt. The conveyor belt is used to transport soybeans, and the heat dissipation device is used to dissipate heat and crush the soybeans on the conveyor belt. The heat dissipation device includes a protective chamber, a first arc-shaped block, a second arc-shaped block, a limiting vibrating element, and extrusion elements. The protective chamber is located above the conveyor belt, and the first and second arc-shaped blocks are fixedly installed inside the protective chamber. The limiting vibrating elements are symmetrically arranged on the upper part of the second arc-shaped block, and multiple extrusion elements are arranged between the limiting vibrating elements. The soybeans on the conveyor belt are lifted by the first arc-shaped block and fall onto the second arc-shaped block. The rotating movement of the limiting vibrating element drives the multiple extrusion elements to rotate and vibrate. When the soybeans on the second arc-shaped block pass through the extrusion elements, they are squeezed and dissipated.

[0007] As a further optimization of the present invention, the heat dissipation device includes first fixing blocks disposed on both sides of the conveyor belt, protective chambers fixedly installed on the two first fixing blocks, the limiting vibration member installed inside the protective chamber, a first transmission member disposed inside the limiting vibration member, the first transmission member being connected to the extrusion member, a second transmission member being disposed on the side of the extrusion member away from the first transmission member, and multiple extrusion members being connected through the second transmission member.

[0008] As a further optimization of the present invention, the limiting vibration component includes a limiting block fixedly installed inside the protective chamber. A first fixing column is fixedly installed on the lower part of the limiting block. A rotating gear is rotatably installed on the side of the limiting block away from the extrusion component. A rotating plate is fixedly installed on the rotating gear. A rotating pull plate is rotatably installed at the end of the rotating plate. A sliding rod is rotatably installed at the end of the rotating pull plate. A sliding motor is provided on the sliding rod. A groove is provided on the limiting block. A first transmission component slides inside the limiting block. The output shaft of the sliding motor is connected to the sliding rod. The end of the sliding rod is connected to the first transmission component. The rotation of the rotating gear drives the output shaft of the sliding motor to slide in the groove inside the limiting block.

[0009] As a further optimization of the present invention, the first transmission component includes a first U-shaped block fixedly installed at the end of the slide rod, a first rotating block rotatably installed inside the first U-shaped block, a first telescopic rod fixedly installed on the side of the first rotating block, a first spring provided on the outside of the first telescopic rod, a second U-shaped block fixedly installed at the end of the first telescopic rod, and a fifth rotating rod rotatably installed inside the second U-shaped block, the fifth rotating rod being connected to the extrusion component.

[0010] As a further optimization of the present invention, the extrusion member includes a fourth fixed column rotatably installed inside the fifth rotating rod, a third fixed block symmetrically arranged fixedly installed on the outside of the fourth fixed column, a cross fixed block fixedly installed on the outside of the third fixed block, the fourth fixed column being symmetrically arranged about the cross fixed block, and an extrusion ring fixedly installed on the outside of the cross fixed block. The extrusion ring is used to extrude soybean clumps. The fourth fixed column on the side away from the second U-shaped block is connected to the second transmission member.

[0011] As a further optimization of the present invention, the second transmission component includes a third U-shaped block rotatably mounted outside the fourth fixed column, a second telescopic rod fixedly mounted on the side of the third U-shaped block, a second spring provided on the outside of the second telescopic rod, and a fourth U-shaped block fixedly mounted on the end of the second telescopic rod away from the third U-shaped block. The plurality of extrusion components are connected through the second transmission component.

[0012] As a further optimization of the present invention, the distance between the bottom of the extruder and the top of the second arc-shaped block is the same as the average diameter of the soybean.

[0013] As a further optimization of the present invention, the top of the first arc-shaped block is higher than the top of the second arc-shaped block, and the bottom of the first arc-shaped block is in contact with the upper transport outer wall of the conveyor belt.

[0014] As a further optimization of the present invention, an elastic isolation element is provided at the connection position between the limiting block and the protective chamber.

[0015] As a further optimization of the present invention, the lengths of the first arc-shaped block and the second arc-shaped block are the same as the width of the conveyor belt.

[0016] The beneficial effects of this invention are as follows: The present invention discloses a soybean raw material conveying device for soy sauce production. Through the first and second arc-shaped blocks on the heat dissipation device, the soybeans transported on the conveyor belt are turned over, thereby improving the heat dissipation effect and making the heat dissipation more uniform. Through the limiting vibration component and the extrusion component, the soybeans can be squeezed when passing through the extrusion component, thereby breaking up the clumps of soybeans without destroying the integrity of individual soybeans. At the same time, the limiting vibration component can drive the extrusion component to move, thereby achieving a vibration effect, accelerating the transportation of soybeans and solving the problem of clumping.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] like Figures 1 to 3 As shown in the embodiment of the present invention, a soybean raw material conveying device for soy sauce production includes a conveyor belt 1, a plurality of support columns 12 are provided on the conveyor belt 1, and a heat dissipation device 2 is provided on the side of the conveyor belt 1. The conveyor belt 1 is used to transport soybeans, and the heat dissipation device 2 is used for heat dissipation and crushing of soybeans on the conveyor belt 1. like Figure 4As shown, the heat dissipation device 2 includes a protective chamber 22, a first arc-shaped block 23, a second arc-shaped block 24, a limiting vibration member 25, and an extrusion member 26. The protective chamber 22 is located above the conveyor belt 1. The first arc-shaped block 23 and the second arc-shaped block 24 are fixedly installed inside the protective chamber 22. The limiting vibration member 25 is symmetrically arranged on the upper part of the second arc-shaped block 24. Multiple extrusion members 26 are arranged between the limiting vibration members 25. The soybeans on the conveyor belt 1 are lifted by the first arc-shaped block 23 and fall onto the second arc-shaped block 24. The limiting vibration member 25 rotates and moves, causing the multiple extrusion members 26 to rotate and vibrate. When the soybeans on the second arc-shaped block 24 pass through the extrusion members 26, they are squeezed and cooled.

[0021] It should be noted that after the soybeans are cooked, they need to be cooled down before being transported to the next processing area. Therefore, after the soybeans are cooked, they are usually transported to the next processing area using conveyor belt 1. During this process, the soybeans may clump together as they cool down, which will affect the subsequent processing effect. Therefore, a stirring device is usually installed on conveyor belt 1 to tumble the soybeans. However, the effect is poor. It is not possible to tumble the soybeans piled at the bottom in contact with conveyor belt 1, nor can it break up the clumps of soybeans on the top. The following improvements have been made to solve this problem. First, cooked soybeans are placed on conveyor belt 1 for transport. Since sparsely distributed soybeans may tumble on conveyor belt 1, they are usually stacked to ensure proper transport. When the soybeans pass the first arc-shaped block 23, they are lifted upwards and fall from the top of the first arc-shaped block 23 onto the second arc-shaped block 24. From there, they roll towards the limiting vibrating element 25. During this rolling process, the soybeans tumble, ensuring thorough tumbling at the bottom and top, improving heat dissipation. The second arc-shaped block 24 is equipped with an extrusion element 26. As the soybeans fall onto the second arc-shaped block 24 and continue falling past the extrusion element 26, they are compressed. This process breaks up clumps of soybeans. A distance exists between the second arc-shaped block 24 and the extruder 26, allowing individual soybeans to pass through, while stacked soybeans cannot. At this point, a motor drives the limiting vibrating element 25 to rotate, which in turn drives the extruder 26 to rotate, facilitating transport and preventing the extruder 26 from stopping and extruding the soybeans, which could damage their shape and affect subsequent processing. The limiting vibrating element 25 vibrates during rotation, allowing the soybeans to fall as they pass the extruder 26, thus resolving the clumping issue and improving the soybean processing efficiency. The soybeans that fall through the extruder 26 then return to the conveyor belt 1 for continued transport, resolving the clumping and tumbling of the soybeans before proceeding to the next processing step.

[0022] like Figures 3 to 4 As shown, the heat dissipation device 2 includes first fixing blocks 21 disposed on both sides of the conveyor belt 1. Protective chambers 22 are fixedly installed on the two first fixing blocks 21. The limiting vibration member 25 is installed inside the protective chamber 22. A first transmission member 27 is disposed inside the limiting vibration member 25. The first transmission member 27 is connected to the extrusion member 26. A second transmission member 28 is disposed on the side of the extrusion member 26 away from the first transmission member 27. Multiple extrusion members 26 are connected through the second transmission member 28.

[0023] It should be noted that the first fixed block 21 is equipped with a protective chamber 22 to prevent soybeans from falling outside the area on the conveyor belt 1 during the upward process. The limiting vibration member 25 can drive the extruder 26 to rotate. Multiple extruders 26 are connected by the second transmission member 28, and the limiting vibration member 25 and the extruder 26 are connected by the first transmission member 27. This allows the soybeans to rise and be subjected to force adaptively when passing through the extruder 26, preventing the soybeans from being damaged before reaching the next process due to excessive force when passing through the extruder 26, thus improving the quality of soybean processing.

[0024] like Figures 5 to 7 As shown, the limiting vibration component 25 includes a limiting block 251 fixedly installed inside the protective chamber 22. A first fixing post 252 is fixedly installed on the lower part of the limiting block 251. A rotating gear 254 is rotatably installed on the side of the limiting block 251 away from the extrusion component 26. A rotating plate 253 is fixedly installed on the rotating gear 254. A rotating pull plate 255 is rotatably installed at the end of the rotating plate 253. A sliding rod 257 is rotatably installed at the end of the rotating pull plate 255. A sliding motor 256 is provided on the sliding rod 257. A groove is provided on the limiting block 251. A first transmission component 27 slides inside the limiting block 251. The output shaft of the sliding motor 256 is connected to the sliding rod 257. The end of the sliding rod 257 is connected to the first transmission component 27. The rotation of the rotating gear 254 drives the output shaft of the sliding motor 256 to slide in the groove inside the limiting block 251.

[0025] It should be noted that the rotating gear 254 is driven by a motor to rotate, which in turn causes the rotating plate 253 to rotate. The rotation of the rotating plate 253 causes it to rotate around the rotating gear 254 as the center. This allows the rotating plate 253 to pull the rotating pull plate 255, causing the slide rod 257 to slide within the groove provided inside the limiting block 251. The end of the rotating pull plate 255 is provided with a sliding motor 256, which can slide on the top of the limiting block 251. Activating the sliding motor 256 causes the slide rod 257 to rotate, which in turn causes the first transmission member 27 to rotate. The first transmission member 27 then causes the extruder 26 to rotate, and moves the extruder 26 along the direction of the groove inside the limiting block 251, creating a shaking effect. This solves the problem of soybeans rolling and clumping. Furthermore, the rotation of the extruder 26 allows soybeans to pass through its position, preventing contact between the soybeans and the outside of the extruder 26, which could cause friction and damage.

[0026] like Figures 6 to 7 As shown, the first transmission component 27 includes a first U-shaped block 271 fixedly installed at the end of the slide rod 257, a first rotating block 272 rotatably installed inside the first U-shaped block 271, a first telescopic rod 273 fixedly installed on the side of the first rotating block 272, a first spring 274 provided on the outside of the first telescopic rod 273, a second U-shaped block 275 fixedly installed at the end of the first telescopic rod 273, a fifth rotating rod 276 rotatably installed inside the second U-shaped block 275, and the fifth rotating rod 276 connected to the extrusion component 26.

[0027] It should be noted that the slide bar 257 is connected to the first U-shaped block 271. Therefore, when the slide bar 257 rotates, it can drive the first rotating block 272, the first telescopic rod 273 and the second U-shaped block 275 to rotate, thereby driving the extruder 26 to rotate. The first telescopic rod 273 can adapt to the height of the soybeans, and the first spring 274 makes the extruder 26 return to its original position, thereby achieving the effects of extrusion and vibration, solving the problems of soybean turning over and clumping. The rotation of the extruder 26 can improve the transportation of soybeans and prevent soybean damage.

[0028] like Figures 5 to 7 As shown, the extrusion member 26 includes a fourth fixed post 263 rotatably mounted inside the fifth rotating rod 276. A third fixed block 262 is symmetrically mounted on the outside of the fourth fixed post 263. A cross fixed block 261 is fixedly mounted on the outside of the third fixed block 262. The fourth fixed post 263 is symmetrically arranged about the cross fixed block 261. An extrusion ring 264 is fixedly mounted on the outside of the cross fixed block 261. The extrusion ring 264 is used to extrude soybean clumps. The side of the fourth fixed post 263 away from the second U-shaped block 275 is connected to the second transmission member 28.

[0029] It should be noted that the fourth fixing post 263 is connected to the cross fixing block 261, and the cross fixing block 261 is provided with a third U-shaped block 281 and a second U-shaped block 275 on both sides. This allows for adaptation when soybeans of different heights pass through during agglomeration, preventing the squeezing ring 264 from excessively squeezing the soybeans and causing them to break, which would affect the subsequent processing effect.

[0030] like Figure 7 As shown, the second transmission component 28 includes a third U-shaped block 281 rotatably mounted outside the fourth fixed column 263. A second telescopic rod 282 is fixedly mounted on the side of the third U-shaped block 281. A second spring 283 is provided on the outside of the second telescopic rod 282. A fourth U-shaped block 284 is fixedly mounted on the end of the second telescopic rod 282 on the side away from the third U-shaped block 281. The plurality of extrusion components 26 are connected through the second transmission component 28.

[0031] It should be noted that multiple extrusion components 26 are connected by a second transmission component 28. The effect of the second transmission component 28 is the same as that of the first transmission component 27. Both can adaptively adjust the angle when soybeans pass by to prevent excessive squeezing of soybeans. The elastic force of the first spring 274 and the second spring 283 is the same, thus ensuring uniform force distribution.

[0032] like Figure 4 As shown, the distance between the bottom of the extruder 26 and the top of the second arc-shaped block 24 is the same as the average diameter of a soybean.

[0033] It should be noted that the distance between the bottom of the extruder 26 and the top of the second arc-shaped block 24 is the same as the average diameter of the soybean. If the distance between the extruder 26 and the second arc-shaped block 24 is too large, it will not be able to achieve the extrusion effect and break up the clumps of soybeans. If the distance between multiple extruders 26 and the second arc-shaped block 24 is too small, the soybeans will easily be damaged when they pass by, making it impossible to proceed to the next step of processing. Therefore, the distance between the extruder 26 and the second arc-shaped block 24 is the same as the average diameter of the soybean, so that the soybeans are extruded when they pass by without damaging them.

[0034] like Figure 4 As shown, the top of the first arc-shaped block 23 is higher than the top of the second arc-shaped block 24, and the bottom of the first arc-shaped block 23 is in contact with the upper transport outer wall of the conveyor belt 1.

[0035] It should be noted that the top of the first arc-shaped block 23 is higher than the top of the second arc-shaped block 24, and the bottom of the first arc-shaped block 23 is in contact with the upper outer wall of the conveyor belt 1. This allows the soybeans on the conveyor belt 1 to rise when they pass the first arc-shaped block 23, and then fall from the first arc-shaped block 23 onto the second arc-shaped block 24 under the action of transportation, thereby achieving a flipping effect and improving the heat dissipation effect.

[0036] like Figure 4 As shown, an elastic isolation element is provided at the connection position between the limiting block 251 and the protective chamber 22.

[0037] It should be noted that an elastic isolator is provided at the connection position between the limiting block 251 and the protective chamber 22 to prevent soybeans from getting stuck at the connection position of the limiting vibration member 25 during transportation and turning, thereby improving the stability of the device operation.

[0038] like Figures 3 to 4 As shown, the lengths of the first arc-shaped block 23 and the second arc-shaped block 24 are the same as the width of the conveyor belt 1.

[0039] It should be noted that the lengths of the first arc-shaped block 23 and the second arc-shaped block 24 are the same as the width of the conveyor belt 1, so that the soybeans transported on the conveyor belt 1 can be raised by the first arc-shaped block 23 and transported to the second arc-shaped block 24, which serves to flip them.

[0040] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the embodiments described above, all of which are within the protection scope of the present invention.
