Abstract
Description
Technical Field
[0001] This utility model relates to the field of soybean extraction technology, and more specifically, to a multi-stage soybean crushing device for soybean extraction. Background Technology
[0002] Enrichment and extraction of γ-aminobutyric acid (GABA) from soybeans is a technology that combines biotransformation, physical separation, and chemical purification. Its core lies in increasing the GABA content by regulating soybean metabolism or utilizing microbial fermentation, and then separating and purifying it through efficient means. Typically, a multi-stage soybean pulverizing device is required. This device is a step-by-step pulverizing equipment designed specifically for the characteristics of soybeans. Through multi-stage processing, it achieves efficient and uniform pulverization of soybean particles and is widely used in food processing, feed production, oil extraction, and other fields.
[0003] Traditional soybean multi-stage crushing devices for soybean extraction have the following shortcomings: In the operation of traditional soybean multi-stage crushing devices, soybeans are first poured into the feed inlet and subjected to primary crushing by toothed rollers. The crushed soybeans are then subjected to secondary crushing by grinding discs before being removed for subsequent extraction steps. During the process of pouring soybeans into the feed inlet, a blower needs to be installed on one side of the feed inlet to remove dust from the soybeans. However, during the blowing process, some smaller soybeans may be blown away from the feed inlet, causing them to scatter outside the equipment and directly resulting in raw material loss. Therefore, improvements are needed. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a multi-stage soybean crushing device for soybean extraction, which has the advantage of preventing soybeans from being blown off.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage soybean crushing device for soybean extraction, comprising a crushing mechanism, a grinding mechanism below the crushing mechanism, a support ring fixedly sleeved on the outer bottom of the grinding mechanism, a support plate welded below the support ring, the crushing mechanism comprising a housing, a feed inlet at the top of the housing, two toothed rollers rotatably mounted inside the housing, the two toothed rollers meshing, adsorption ports on both sides of the top of the housing, covers welded to both ends of the housing outside the adsorption ports, adsorption mechanisms on both sides of the housing, the adsorption mechanisms comprising platforms bolted to both sides of the housing, a connection port at the top of the platform, a connecting pipe fixedly sleeved inside the connection port, the other end of the connecting pipe fixedly connected to the rear side of the cover, a slot at the bottom of the platform, a filter plate bolted inside the slot, and a fan bolted inside the slot below the filter plate.
[0006] As a preferred embodiment of this utility model, the grinding mechanism includes a cylindrical body welded to the lower part of the shell. A grinding disc is rotatably mounted inside the cylindrical body. An arc-shaped groove is formed above the grinding disc, and a vertical groove is formed below the arc-shaped groove. An arc-shaped groove extending to the bottom of the grinding disc is formed below the vertical groove. A fixing plate is welded inside the cylindrical body, and a bottom plate is welded above the fixing plate. A gap is provided between the bottom plate and the grinding disc. A discharge port is formed on the outer side of the bottom plate, and a discharge pipe is fixedly installed at the bottom of the cylindrical body.
[0007] As a preferred embodiment of this utility model, a second servo motor is fixedly installed on the front side of the housing, and the output end of the second servo motor extends into the interior of the housing and is fixedly connected to the front side of the toothed roller.
[0008] As a preferred embodiment of this utility model, baffles are welded to both sides of the inner side of the housing, located above the toothed roller, and the baffles are located below the adsorption port.
[0009] As a preferred embodiment of this utility model, a servo motor is installed inside the fixing plate by bolts. The output end of the servo motor penetrates through the base plate and is fixedly connected to the bottom of the grinding disc.
[0010] As a preferred embodiment of this utility model, a slope is provided on the inner side of the bottom of the shell, and a discharge port extending into the slope is provided at the bottom of the shell, the discharge port being located above the grinding disc.
[0011] As a preferred embodiment of this utility model, a vertical plate is welded and installed at the bottom of the housing, and the bottom side of the vertical plate is in close contact with the upper side of the grinding disc.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model generates negative pressure inside the empty trough by activating a fan. This negative pressure, through the connecting pipe and the cover, creates an adsorption force below the adsorption port, adsorbing dust from soybeans falling from the feed inlet. A baffle blocks soybeans whose movement trajectory deviates. Compared to traditional multi-stage soybean crushing devices for soybean extraction, this device uses a fan to generate negative pressure below the adsorption port, creating an adsorption force to adsorb dust and other contaminants from the soybeans, thus improving the soybean detection effect. Simultaneously, the baffle prevents displaced soybeans from falling to either side of the toothed roller, thus avoiding the crushing effect. The adsorption force is generated inside the shell, preventing soybeans from falling to the outside and avoiding raw material loss.
[0014] 2. This utility model uses a vertical plate to block the soybeans above the grinding disc. Under the rotational force of the grinding disc, the soybeans move into the interior of the second arc-shaped groove. The grinding disc and the bottom plate grind the soybeans into powder. The powdered soybeans are then removed through the discharge pipe for subsequent extraction operations. Compared with traditional soybean multi-stage grinding devices for soybean extraction, this soybean multi-stage grinding device uses a vertical plate to block the soybeans and, under the action of the grinding disc, moves the soybeans into the interior of the second arc-shaped groove, thus preventing soybeans from remaining above the grinding disc and affecting subsequent use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5As shown, this utility model provides a multi-stage soybean crushing device for soybean extraction, including a crushing mechanism 1, a grinding mechanism 3 below the crushing mechanism 1, a support ring 5 fixedly sleeved on the outer bottom of the grinding mechanism 3, and a support plate 6 welded below the support ring 5. The crushing mechanism 1 includes a housing 11, with a feed inlet 12 at the top of the housing 11. Two toothed rollers 13 are rotatably mounted inside the housing 11, and the two toothed rollers 13 mesh with each other. Adsorption ports 18 are opened on both sides of the top of the housing 11, and the two ends of the housing 11 are welded to the sides. A cover 7 is attached to the outside of the adsorption port 18. Adsorption mechanisms 2 are provided on both sides of the housing 11. The adsorption mechanism 2 includes a platform 22 bolted to both sides of the housing 11. A connection port 23 is provided on the top of the platform 22. A connecting pipe 21 is fixedly sleeved inside the connection port 23. The other end of the connecting pipe 21 is fixedly connected to the rear side of the cover 7. A slot 24 is provided at the bottom of the platform 22. A filter plate 25 is bolted inside the slot 24. A fan 26 located below the filter plate 25 is bolted inside the slot 24.
[0023] In use, first start the servo motor 24 and fan 26, so that the servo motor 24 drives the toothed roller 13 to rotate, and pour the soybeans into the inside of the shell 11 from the feed port 12. At this time, the rotation of the feed port 12 creates a negative pressure inside the empty trough 24. Through the connecting pipe 21 and the cover 7, a suction force is generated below the adsorption port 18 to absorb the dust mixed in with the soybeans and absorb the dust into the inside of the empty trough 24. The dust is filtered by the filter plate 25, and the filtered gas is discharged from below the fan 26. When a small soybean deviates from its trajectory due to the suction force, the baffle 14 blocks the larger soybeans, causing the soybeans to fall between the inner sides of the toothed roller 13 through the baffle 14. The toothed roller 13 then performs primary crushing of the soybeans.
[0024] By activating the fan 26 to create negative pressure inside the empty trough 24, an adsorption force is generated below the adsorption port 18 through the connecting pipe 21 and the cover 7, adsorbing dust from soybeans falling from the feed port 12. The baffle 14 blocks soybeans whose movement trajectory deviates. Compared with traditional soybean multi-stage crushing devices for soybean extraction, this soybean multi-stage crushing device uses the fan 26 to generate negative pressure below the adsorption port 18 to adsorb dust and other substances from soybeans, thus improving the soybean detection effect. At the same time, the baffle 14 blocks the deviated soybeans, preventing them from falling to both sides of the toothed roller 13 and affecting the crushing effect. The adsorption force is generated inside the shell 11, thus preventing soybeans from falling to the outside of the shell 11 and avoiding the problem of raw material loss.
[0025] The grinding mechanism 3 includes a cylindrical body 32, which is welded to the lower part of the shell 11. A grinding disc 31 is rotatably installed inside the cylindrical body 32. An arc groove 37 is provided above the grinding disc 31, and a vertical groove 33 is provided below the arc groove 37. An arc groove 34 extending to the bottom of the grinding disc 31 is provided below the vertical groove 33. A fixing plate 39 is welded inside the cylindrical body 32, and a bottom plate 35 is welded above the fixing plate 39. A gap is provided between the bottom plate 35 and the grinding disc 31. A discharge port 36 is provided on the outer side of the bottom plate 35, and a discharge pipe 8 is fixedly installed at the bottom of the cylindrical body 32.
[0026] After initial crushing, the soybeans fall onto the grinding disc 31. The servo motor 38 drives the grinding disc 31 to rotate, and the vertical plate 16 pushes the soybeans above the grinding disc 31. Under the rotation of the grinding disc 31, the soybeans are pushed to the top of the arc groove 37, so that the soybeans fall into the interior of the arc groove 34 through the vertical groove 33. The grinding disc 31 and the bottom plate 35 grind the soybeans into powder. The soybean powder falls into the bottom of the cylinder 32 through the feed port 36, and then the crushed soybeans are taken out through the discharge pipe 8.
[0027] The vertical plate 16 blocks the soybeans above the grinding disc 31, and the rotational force of the grinding disc 31 causes the soybeans to move into the interior of the arc-shaped groove 37. The grinding disc 31 and the bottom plate 35 grind the soybeans into powder, and the powdered soybeans are taken out through the discharge pipe 8 for subsequent extraction operations. Compared with the traditional soybean multi-stage grinding device for soybean extraction, this soybean multi-stage grinding device for soybean extraction uses the vertical plate 16 to block the soybeans and causes the soybeans to move into the interior of the arc-shaped groove 37 under the action of the grinding disc 31, thereby preventing soybeans from remaining above the grinding disc 31 and affecting subsequent use.
[0028] Servo motor 4 is fixedly installed on the front side of housing 11. The output end of servo motor 4 extends into the interior of housing 11 and is fixedly connected to the front side of toothed roller 13.
[0029] Start the servo motor 4, which drives the toothed roller 13 to rotate. The rotation of the two toothed rollers 13 performs primary crushing of the soybeans between them.
[0030] The housing 11 has baffles 14 welded to both sides of its interior, above the toothed roller 13, and the baffles 14 are located below the adsorption port 18.
[0031] The baffle 14 blocks the soybeans whose movement trajectory has deviated, thereby preventing the soybeans from falling to both sides of the toothed roller 13 and affecting subsequent crushing.
[0032] The servo motor 38 is installed inside the fixing plate 39 by bolts. The output end of the servo motor 38 passes through the base plate 35 and is fixedly connected to the bottom of the grinding disc 31.
[0033] Start the servo motor 38 to drive the grinding disc 31 to rotate, thereby grinding the soybeans between the grinding disc 31 and the base plate 35 into powder.
[0034] The bottom inner side of the housing 11 is provided with a ramp 15, and the bottom of the housing 11 is provided with a discharge port 17 extending into the ramp 15. The discharge port 17 is located above the grinding disc 31.
[0035] By setting up a ramp 15, soybeans that fall onto the ramp 15 are moved into the inside of the discharge port 17 under the action of gravity, preventing soybeans from remaining inside the shell 11 and affecting the next use.
[0036] A vertical plate 16 is welded to the bottom of the housing 11, and the bottom side of the vertical plate 16 is in close contact with the upper side of the grinding disc 31.
[0037] The vertical plate 16 blocks the soybeans above the grinding disc 31, causing the soybeans to fall into the interior of the arc-shaped groove 37 as the grinding disc 31 rotates.
[0038] Working principle and usage process of this utility model:
[0039] In use, first start the servo motor 24 and fan 26, so that the servo motor 24 drives the toothed roller 13 to rotate, and pour the soybeans into the inside of the shell 11 from the feed port 12. At this time, the rotation of the feed port 12 creates a negative pressure inside the empty trough 24. Through the connecting pipe 21 and the cover 7, a suction force is generated below the adsorption port 18 to absorb the dust mixed in with the soybeans and absorb the dust into the inside of the empty trough 24. The dust is filtered by the filter plate 25, and the filtered gas is discharged from below the fan 26. When a small soybean deviates from its trajectory due to the suction force, the baffle 14 blocks the larger soybeans, causing the soybeans to fall between the inner sides of the toothed roller 13 through the baffle 14. The toothed roller 13 then performs primary crushing of the soybeans.
[0040] After initial crushing, the soybeans fall onto the grinding disc 31. The servo motor 38 drives the grinding disc 31 to rotate, and the vertical plate 16 pushes the soybeans above the grinding disc 31. Under the rotation of the grinding disc 31, the soybeans are pushed to the top of the arc groove 37, so that the soybeans fall into the interior of the arc groove 34 through the vertical groove 33. The grinding disc 31 and the bottom plate 35 grind the soybeans into powder. The soybean powder falls into the bottom of the cylinder 32 through the feed port 36, and then the crushed soybeans are taken out through the discharge pipe 8.
