Description

Technical Field

[0001] The invention relates to the technical field of soybean crushing, in particular to a soybean crusher for soybean oil production. Background Art

[0002] With the continuous development of the food industry, vegetable oil, as one of the necessities in people's daily life, has also been significantly improved in production and processing technology. As an important source of vegetable oil, the production process of soybean oil mainly includes raw material preparation, crushing, leaching or pressing, refining and other steps. Among them, soybean crushing is the key link in soybean oil production, which not only affects the smooth progress of subsequent processes, but also directly affects the quality and output of the final product.

[0003] In the soybean crushing process, the performance of the crusher used will directly affect the crushing effect of soybeans and the extraction rate of oil. However, the existing soybean crushers still face some problems in practical applications: First, due to the frictional heat effect generated during the crushing process, the protein in the soybeans will denature due to the increase in temperature. This change not only affects the sensory properties of soybean oil such as color and flavor, but also reduces its nutritional value, thereby affecting the overall quality of soybean oil. Secondly, the material is prone to jamming inside the crusher, which will increase the operating load of the motor. If it is not discovered in time, it may also cause the motor to overload or even damage, thereby affecting the overall production efficiency. In addition, once the material jam occurs, it is necessary to shut down and manually clear the blocked material by the staff. This process is not only time-consuming and labor-intensive, but also has certain safety hazards. Summary of the invention

[0032] like Figure 4 and Figure 5As shown, the moving assembly includes a guide rail 10, a sliding seat 11, a first electric push rod 12, a first fixed plate 13, a second fixed plate 14 and a control switch 15. The guide rail 10 is connected to the right side of the top of the mounting frame 1, and the sliding seat 11 is slidably connected to the guide rail 10. The bottom of the first drive motor 8 is connected to the top of the sliding seat 11 by bolts. The first electric push rod 12 is also connected to the right side of the top of the mounting frame 1, and the telescopic rod of the first electric push rod 12 is connected to the left side of the sliding seat 11. The first fixed plate 13 and the second fixed plate 14 are respectively connected to the two rotors of the magnetic coupler 9, and the control switch 15 is installed on the front side of the first fixed plate 13, and the control switch 15 is electrically connected to the first electric push rod 12.

[0033] like Figure 6-Figure 9 As shown, the discharging mechanism includes a hand wheel 16, an industrial vacuum cleaner 17, a sliding pipe 18, a rotating plate 19, a torsion spring 20, a rubber valve 21 and a driving assembly. The right end of the rotating shaft of the front crushing roller 3 is connected with the hand wheel 16, and the industrial vacuum cleaner 17 is installed on the right side of the lower part of the mounting frame 1. The sliding pipe 18 is slidably connected to the hollow frame 6 on the right side, and the sliding pipe 18 slides through the right side of the shell 2. The end of the dust suction pipe 1701 of the industrial vacuum cleaner 17 is connected to the right end of the sliding pipe 18, and the lower left end of the sliding pipe 18 is rotatably connected with the rotating plate 19, and the torsion spring 20 is wound around the front and rear sides of the rotating shaft of the rotating plate 19, and the two ends of the torsion spring 20 The ends are respectively connected to the sliding tube 18 and the rotating plate 19, four rubber valves 21 are symmetrically connected to the right side of the inner wall of the shell 2, the four rubber valves 21 are in contact with each other to form a circle, and block the left end of the sliding tube 18, and the driving component is used to drive the sliding tube 18 to move; the driving component includes a conveying wheel 22 and a second driving motor 23, the upper right side of the hollow frame 6 on the right side is rotatably connected to the two conveying wheels 22, and the sliding tube 18 passes between the two conveying wheels 22, and the second driving motor 23 is installed in the middle part of the right side of the hollow frame 6 on the right side, and the output shaft of the second driving motor 23 is connected to the lower end of the rotating shaft of the rear conveying wheel 22.

[0034] Initially, the shell 2 is against the bottom of the rotating plate 19, and the torsion spring 20 is in a deformed state; when the soybeans need to be crushed, the first drive motor 8 is started first, and the first drive motor 8 can drive the crushing roller 3 on the rear side to rotate counterclockwise through the magnetic coupler 9. At this time, the two rotors of the magnetic coupler 9 have the same speed, that is, the first fixed plate 13 and the second fixed plate 14 are relatively stationary. At the same time, under the transmission action of the connecting gear 4, the crushing roller 3 on the front side can also be driven to rotate clockwise. Since the first drive motor 8 needs to overcome the inertia in the static state when it is just started, the first drive motor 8 is The speed in the early stage is relatively low, and it is in a gradually accelerating state. After both crushing rollers 3 reach the specified speed, the soybeans can be poured into the feeding frame above the shell 2, so that the soybeans can gradually fall down into the shell 2. Since the rubber valve 21 blocks the left end of the sliding tube 18, the soybeans in the shell 2 will not enter the sliding tube 18. When the soybeans contact the crushing rollers 3 in the shell 2, the two crushing rollers 3 rotate in opposite directions to squeeze and crush the soybeans. The crushed soybeans will fall down to the discharge inclined plate below the shell 2 through the gap between the two crushing rollers 3 due to gravity, and slide forward and downward along the discharge inclined plate. The falling materials are convenient for manual unified collection and processing; during the soybean crushing period, the air cooler 7 can be started, and the air duct of the air cooler 7 can convey the cold air to the hollow frame 6 on the right side, and enter the through hole 302 of the crushing roller 3 through the vent hole on the right side of the shell 2. The fins 5 in the through hole 302 can perform heat exchange between the crushing roller 3 and the cold air, thereby cooling the crushing roller 3 to prevent the crushing roller 3 from heating up due to long-term operation, which causes the protein in the soybean to denature, thereby ensuring the quality of the subsequent soybean oil; when the material is stuck between the two crushing rollers 3, the rotor speed on the left side of the magnetic coupler 9 is increased. will be lowered, at this time the first fixed plate 13 and the second fixed plate 14 will gradually approach each other, when the second fixed plate 14 presses the control switch 15 on the first fixed plate 13, the control switch 15 will control the first electric push rod 12 to drive the sliding seat 11 to move rightward along the guide rail 10, driving the first drive motor 8 to move rightward, the first drive motor 8 can drive the rotor on the right side of the magnetic coupler 9 to move rightward, so that the two rotors of the magnetic coupler 9 are away from each other, so that the crushing roller 3 can stop rotating, preventing the operating load of the first drive motor 8 from increasing, thereby preventing the first drive motor 8 from being overloaded or damaged;When the operator sees that the two rotors of the magnetic coupler 9 are separated, he can also know in time that the crushing roller 3 is stuck. At this time, the first drive motor 8 can be controlled to stop working, and then the hand wheel 16 can be manually controlled to rotate counterclockwise, so that the front crushing roller 3 can be driven to rotate counterclockwise. Under the transmission action of the connecting gear 4, the rear crushing roller 3 can be driven to rotate clockwise. At this time, the two crushing rollers 3 are in a back-to-back rotation state, so that the soybeans stuck between the two crushing rollers 3 can be slightly lifted up to prevent the soybeans from being stuck too tightly. Then the second drive motor 23 and the industrial vacuum cleaner 17 are controlled to start working. The second drive motor 23 can drive the rear conveying wheel 22 to rotate. Under the cooperation of the two conveying wheels 22, the sliding tube 18 can be driven to move to the left. The sliding tube 18 will squeeze the rubber valve 21 to bend to the left and deform. At this time, the left end of the sliding tube 18 will enter the shell 2, and the sliding tube 18 will drive the rotating plate 19 to move to the left and separate from the shell 2. The torsion spring 20 returns to its original state, which can drive the rotating plate 19 to rotate downward and open to be inclined. The industrial vacuum cleaner 17 can generate suction at the left end of the sliding tube 18. As the rotating plate 19 continues to move to the left, the rotating plate 19 can scoop up the soybeans stuck between the two crushing rollers 3 and move the soybeans along the top of the rotating plate 19 into the sliding tube 18. Then the industrial vacuum cleaner 17 can suck out the soybeans in the sliding tube 18. When the left end of the sliding tube 18 moves to the left side of the inner wall of the shell 2, the industrial vacuum cleaner 17 can be controlled to stop working, and the second drive motor 23 can be controlled to drive the rear conveying wheel 22 to reverse. With the cooperation of the conveying wheel 22, the sliding tube 18 can be driven to move rightward and reset, and the sliding tube 18 will drive the rotating plate 19 to move rightward and reset. When the rotating plate 19 contacts the shell 2, the shell 2 will squeeze the rotating plate 19 to rotate upward and retract, and the torsion spring 20 will deform. When the left end of the sliding tube 18 is separated from the rubber valve 21, the rubber valve 21 will recover due to its own elasticity and block the left end of the sliding tube 18 again to prevent the soybeans from entering the sliding tube 18. At this time, the above operation can be repeated to crush the soybeans again. ;

[0035] like Fig.10As shown, it also includes an arc rod 24 and an elastic membrane 25. The left end of the sliding tube 18 is symmetrically connected to the arc rod 24, and the right side of the inner wall of the hollow frame 6 on the right side is symmetrically connected to the arc rod 24. The number of the arc rods 24 is four, and the curvature of the arc rod 24 is consistent with the curvature of the outer wall of the crushing roller 3. The elastic membrane 25 is connected between the two corresponding arc rods 24 on the left and right, and the elastic membrane 25 slides through the right side of the shell 2; when the sliding tube 18 moves to the left, the sliding tube 18 can drive the arc rod 24 on the left to move to the left, so that the elastic membrane 25 can be stretched and deformed, so that the elastic membrane 25 covers The crushing roller 3 is above the crushing roller 3, so that the crushing roller 3 and the soybeans above it can be separated. After the soybeans stuck between the two crushing rollers 3 are cleaned up, the two crushing rollers 3 can be controlled to rotate towards each other. When the crushing rollers 3 reach the specified speed, the sliding tube 18 is controlled to move rightward and reset. The sliding tube 18 can drive the arc rod 24 on the left to move rightward and reset. The elastic membrane 25 can shrink and recover due to its own elasticity, so that the soybeans can fall down to the crushing roller 3 for crushing. In this way, the soybeans can be separated at the initial stage of the crushing roller 3 to avoid the material jamming due to insufficient rotation speed of the crushing roller 3.

[0036] like Fig.11 and Fig.12 As shown, it also includes a hollow seat 26, a rotating network tube 27, a transmission gear 28, a fixed seat 29 and a column gear 30. The hollow seat 26 is connected to the rear side of the top of the hollow frame 6 on the left, and the interior of the hollow seat 26 is connected to the interior of the hollow frame 6 on the left. The rotating network tube 27 is rotatably connected to the middle of the shell 2. Both the left and right ends of the rotating network tube 27 are open-type designs, and the left end of the rotating network tube 27 is rotatably connected to the hollow seat 26 and maintained in communication. The transmission gear 28 is connected to the left end of the rotating network tube 27. The fixed seat 29 is connected to the front side of the top of the hollow frame 6 on the left. The column gear 30 is composed of two gears and a rotating column. The rotating column is rotatably connected to the fixed seat 29. Gears are connected to both ends of the rotating column. The gear on the left is meshed with the connecting gear 4 on the front side, and the gear on the right is meshed with the transmission gear 28.

[0037] When the crushing roller 3 is rotating, the connecting gear 4 on the front side can drive the rotating mesh tube 27 to rotate through the transmission action of the column gear 30 and the transmission gear 28. At the same time, the cold air flowing out from the left end of the through hole 302 will pass through the vent holes on the left side of the shell 2, the hollow frame 6 on the left side and the hollow seat 26 in sequence, and finally enter the rotating mesh tube 27. The rotating mesh tube 27 can dissipate the cold air into the shell 2, thereby cooling the soybeans in the shell 2 to prevent the soybeans from accumulating and generating high temperature. Since the rotating mesh tube 27 is in a state of continuous rotation, the mesh of the rotating mesh tube 27 can be prevented from being blocked by soybeans. Since the entire device is in a state of continuous cooling of the crushing roller 3 during operation, the temperature of the cold air flowing out from the left end of the through hole 302 is also relatively low, which can have a certain cooling effect on the soybeans in the shell 2.

[0038] like Fig.11 and Fig.13 As shown, it also includes a bellows 31, a cylindrical desiccant box 32, a circular magnet 33 and a magnetic ring 34. The bellows 31 is connected to the middle part of the right side of the shell 2. A cylindrical desiccant box 32 is arranged inside the bellows 31. The diameter of the cylindrical desiccant box 32 is slightly smaller than the diameter of the rotating mesh tube 27. The left end of the cylindrical desiccant box 32 is located at the right end of the rotating mesh tube 27. The cylindrical desiccant box 32 can move to the left and enter the rotating mesh tube 27. A circular magnet 33 is connected to the right side of the cylindrical desiccant box 32. A handle is connected to the right side of the circular magnet 33. The right end of the bellows 31 is connected to the magnetic ring 34, and the magnetic ring 34 and the circular magnet 33 are attracted to each other by magnetic force.

[0039] Initially, the bellows 31 covers the outside of the cylindrical moisture absorption box 32 to prevent the outside air from affecting the subsequent use of the cylindrical moisture absorption box 32; when the device is not used for a period of time, the humidity inside the shell 2 may be high due to environmental influences, so before the soybeans are crushed, the circular magnet 33 can be pushed to the left, and the circular magnet 33 can drive the cylindrical moisture absorption box 32 to move to the left and enter the rotating mesh tube 27, and the circular magnet 33 can drive the magnetic ring 34 to move to the left, so that the bellows 31 is shortened, and the cylindrical moisture absorption box 32 can be used to crush the shell 2 Dehumidification is performed inside to prevent the soybeans in the shell 2 from getting stuck due to excessive humidity. After dehumidification, the circular magnet 33 can be pulled to the right, and the circular magnet 33 can drive the cylindrical moisture absorption box 32 to move to the right and separate from the rotating mesh tube 27, and the circular magnet 33 can drive the magnetic ring 34 to move to the right, so that the bellows 31 stretches and recovers. When the cylindrical moisture absorption box 32 needs to be replaced, the circular magnet 33 can be pulled to the right until it is separated from the magnetic ring 34, and then the cylindrical moisture absorption box 32 can be taken out from the inside of the bellows 31 for replacement.

[0040] like Fig.14 As shown, it also includes a guide rod 35, a movable cylinder 36, a lever 37, a second electric push rod 38 and a connecting ring 39. The guide rod 35 is symmetrically connected to the lower inner side of the shell 2, and the two guide rods 35 are both sleeved with movable cylinders 36, that is, the movable cylinders 36 can move left and right along the guide rods 35, and can also rotate around the guide rods 35. The outer walls of the two movable cylinders 36 are connected with levers 37 at circumferential intervals, and the levers 37 are in contact with the inclined groove 301. The second electric push rods 38 are symmetrically connected to the lower right side of the shell 2, and the telescopic rods of the two second electric push rods 38 are connected with connecting rings 39, the connecting rings 39 correspond to the movable cylinders 36 one by one, and the right end of the movable cylinder 36 is rotatably connected to its corresponding connecting ring 39.

[0041] When the crushing roller 3 is rotating, the crushing roller 3 can drive the movable cylinder 36 to rotate through the contact and cooperation between the inclined groove 301 and the lever 37. At the same time, the second electric push rod 38 can drive the connecting ring 39 to reciprocate left and right. The connecting ring 39 can drive the movable cylinder 36 to reciprocate left and right along the guide rod 35, so that the lever 37 can move in the inclined groove 301, thereby being able to push out the soybean particles remaining in the inclined groove 301, thereby reducing the frequency of the crushing roller 3 getting stuck.

[0042] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
