Description

Technical Field

[0001] The invention belongs to the technical field of soybean processing, and in particular relates to a crushing and grinding integrated machine for producing soybean powder. Background Art

[0002] Soybean is an annual herb of the genus Glycine max in the family Fabaceae. It is 30-90 cm tall and has a protein content of 35% to 40%. Genetically modified soybeans are round in shape, with thick, upright stems densely covered with long brown hairs. Soybean raw materials can be made into many types of delicacies, but before being made into delicacies, the soybean raw materials need to be processed.

[0003] In the prior art (the announcement number is CN212915895U, and the patent name is a patent application for a crushing and grinding machine for soybean powder production), the crushing and grinding speed is improved to ensure the quality of soybean crushing and grinding. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art.

[0004] During the crushing and grinding of soybean raw materials, most of the time, crushing shafts, crushing leaves and other tools are used to crush soybeans. Since soybeans are round in shape, it is more difficult for such tools to contact with the soybean raw materials, which reduces the crushing force area between the tools and the soybean raw materials, and also reduces the crushing force points of the soybean raw materials, resulting in insufficient crushing of the soybeans, which increases the difficulty of subsequent grinding.

[0005] At the same time, the existing grinding method is based on concentrated grinding of the crushed soybeans. Due to the gaps in the grinding components, the soybeans are not fully ground, which prolongs the grinding time of the soybeans. At the same time, concentrated grinding of the soybeans also increases the grinding strength of the grinding components, which is time-consuming and labor-intensive. Summary of the invention

DETAILED DESCRIPTION

[0042] The present invention is specifically described below in conjunction with the accompanying drawings and specific embodiments:

[0045] like Figure 5-Figure 12As shown, the crushing assembly 6 also includes a turntable 62 fixed on the output shaft of the servo motor 61, and a convex head 63 is fixedly connected to one side of the turntable 62, and a lifting frame 64 is slidably connected to the convex head 63.

The lifting frame 64 then drives the gravity seat 66 through the lifting arm 65 to reciprocate and crush the soybean raw materials at the bottom of the crushing box 3 by gravity, so that the soybeans are fully crushed, which provides convenience for subsequent grinding;

[0046] A sliding sleeve slidably matched with the lifting arm 65 is embedded in the center of the top of the crushing box 3, which plays a role of sliding support for the lifting arm 65 and improves the lifting smoothness of the lifting arm 65. The bottom of the inner cavity of the crushing box 3 adopts a thickened design used in combination with the gravity seat 66 to enhance the downward pressure bearing capacity of the bottom of the crushing box 3 on the gravity seat 66 and enhance the gravity crushing effect of the gravity seat 66 on the soybean raw material.

[0047] The rotating assembly 7 also includes convex teeth 71 circumferentially fixed on both sides of the rotating disk 62 and meshingly connected with the intermediate gear 72, and the bottom of the intermediate gear 72 is meshed with a double-sided gear ring 73, and the convex teeth 71 on the rotating disk 62 drive the double-sided gear ring 73 to rotate through the intermediate gear 72, and the inner cavity of the double-sided gear ring 73 is meshed with differential gears 74 all around, and the double-sided gear ring 73 drives four sets of differential gears 74 to follow the rotation, and the inner side of the differential gear 74 is meshed with planetary gears 75, and the inner cavities of the differential gears 74 and the planetary gears 75 are fixedly connected with a rotating rod 76 that rotates with the fixed cover 2 and the grinding box 5. While the four sets of differential gears 74 drive the middle planetary gear 75 to rotate, the four sets of differential gears 74 and the planetary gears 75 drive the five rotating rods 76 to rotate, thereby providing rotational power for subsequent soybean grinding;

[0048] The grinding assembly 8 includes a material distribution manifold 81 connected to the crushing box 3 and the grinding box 5 on opposite sides, and the inner cavity of the grinding box 5 is provided with a material distribution chamber 82 connected to the material distribution manifold 81 on all sides. The two sets of material distribution manifolds 81 divide the crushed soybean particles in the crushing box 3 into a plurality of material distribution chambers 82, so that the soybean particles are ground in different areas. A large grinding head 83 is fixed on the inner wall circumference of the material distribution chamber 82, and a main grinding ball 84 and an auxiliary grinding ball 85 used in conjunction with the material distribution chamber 82 are fixedly connected to the rotating rod 76. The main grinding ball 84 and the auxiliary grinding ball 85 are respectively fixedly connected to the rotating rod 76. Small grinding heads 86 are fixed on the circumference of the grinding balls 85, which are staggered with the large grinding heads 83. Under the staggered cooperation of the small grinding heads 86 and the large grinding heads 83, the rotating rods 76 on the four sets of differential gears 74 drive the four sets of main grinding balls 84 to efficiently grind the soybean particles arriving in the material distribution chamber 82 in different areas, and the rotating rods 76 on the planetary gears 75 drive the auxiliary grinding balls 85 to efficiently grind the soybean particles also arriving in the material distribution chamber 82 in different areas, thereby achieving the soybean grinding effect, improving the grinding sufficiency of the soybean, shortening the soybean grinding time, and saving time and labor.

[0049] An annular slide groove 15 is provided on one side of the fixed cover 2 close to the double-sided gear ring 73, and the inner cavity of the annular slide groove 15 is slidably connected to the four sides with a T-shaped slide 16 fixedly matched with the double-sided gear ring 73, which plays a role of rotational support for the double-sided gear ring 73 and improves the rotational stability of the double-sided gear ring 73. The differential gear 74 and the main grinding ball 84 are distributed in an axially symmetrical and equidistant state along the horizontal axis of the planetary gear 75 and the auxiliary grinding ball 85, and the soybean particles in several distribution chambers 82 are fully divided and ground. The two sides of the bottom of the grinding box 5 are connected to the discharge pipe 17 connected and matched with the distribution chamber 82 in an array, so that the soybean powder obtained after grinding is in place can be discharged.

[0050] like Figure 14-15 As shown, during the crushing of soybeans, due to the limitation of the shape of soybeans, the traditional cutters cannot effectively crush the soybeans, which increases the difficulty of subsequent grinding, and the soybeans cannot be interspersed with extrusion crushing operations based on gravity crushing. The inner cavity of the extension cover 4 is provided with an extrusion component 9 used in conjunction with the crushing component 6, and the extrusion component 9 includes a belt groove 91 provided on the turntable 62, and both sides of the inner cavity of the fixed frame 1 are rotatably connected with synchronous wheels 92 that cooperate with the belt groove 91 through a synchronous belt drive, and the belt groove 91 on the turntable 62 drives the two sets of synchronous wheels 92 to rotate through the synchronous belt;

[0051] The inner cavity of the synchronous wheel 92 is fixedly connected with a concave rod 93 that rotates with the extension cover 4, and a rotating sleeve 94 is rotatably connected to the concave rod 93, and a connecting rod 95 is fixedly connected to the rotating sleeve 94. The inner side of the connecting rod 95 is hinged with an extrusion seat 96 that slides with the extension cover 4 and adopts a through-design with the crushing box 3. The two sets of synchronous wheels 92 drive the extrusion seats 96 on the two connecting rods 95 to perform an extrusion action at the bottom of the crushing box 3 through the rotating sleeves 94 on the two concave rods 93, and form an alternating interlacing movement with the gravity seat 66, so as to perform interlaced extrusion and crushing of the soybeans at the bottom of the crushing box 3, thereby improving the crushing degree of the soybeans, and guide rail grooves 10 are provided on both sides of the inner cavity of the extension cover 4, and the inner cavity of the guide rail groove 10 is slidably connected with a guide rail bar 11 that is fixedly matched with the extrusion seat 96, providing a sliding limit fit for the extrusion seat 96, thereby improving the displacement stability of the extrusion seat 96 during the extrusion and crushing of the soybeans.

[0052] The working principle of a crushing and grinding machine for soybean powder production is as follows: first, pour the soybean raw materials to be processed from the feeding hopper into the bottom of the crushing box 3, then control the servo motor 61 to start and drive the turntable 62 to rotate, and the slide rail frame 13 and the slide rail block 14 provide sliding support for the lifting frame 64, then the convex head 63 on the turntable 62 drives the lifting frame 64 to perform reciprocating lifting motion, and the lifting frame 64 drives the lifting arm 65 to move in the crushing box 3, and performs frequency stretching and compression on the buffer spring 12, then the lifting arm 65 in the reciprocating lifting motion drives the gravity seat 66 to perform frequency gravity crushing processing on the soybean raw materials at the bottom of the crushing box 3;

[0053] At the same time, the belt groove 91 on the turntable 62 drives the concave rods 93 on the two sets of synchronous wheels 92 to rotate through the synchronous belt, and the guide groove 10 and the guide bar 11 provide sliding limit cooperation for the extrusion seat 96. Then, the two concave rods 93 drive the extrusion seats 96 on the two connecting rods 95 through the two sets of rotating sleeves 94 to perform back and forth extrusion on both sides of the bottom of the crushing box 3, and form an alternating interlaced motion with the gravity seat 66 of the reciprocating lifting motion, that is, when the gravity seat 66 moves down to crush the soybean raw material by gravity, the two sets of extrusion seats 96 move outward synchronously and are at the initial positions on both sides of the bottom of the crushing box 3, and block both sides of the bottom of the crushing box 3. When the gravity seat 66 moves up and resets during the return stroke, the two sets of extrusion seats 96 move inward synchronously and extrude and crush the soybean grains after gravity crushing, and the soybean raw material at the bottom of the crushing box 3 is fully crushed in this reciprocating manner.

[0054] After the soybean raw materials at the bottom of the crushing box 3 are fully crushed, the two-group material manifold 81 is controlled to open and the soybean crushed grains at the bottom of the crushing box 3 are divided into several material distribution chambers 82 in the grinding box 5. At the same time, the annular chute 15 and the T-shaped slide 16 provide rotation support for the double-sided gear ring 73, and the convex teeth 71 on the turntable 62 drive the double-sided gear ring 73 to rotate through the transfer gear 72, and the double-sided gear ring 73 drives the four sets of differential gears 74 to rotate accordingly, and the four sets of differential gears 74 drive the planetary gears 75 to rotate accordingly;

[0055] The four sets of differential gears 74 drive the main grinding ball 84 to rotate in the material distribution chamber 82 at this position through the four rotating rods 76. Under the grinding cooperation of the large grinding head 83, the small grinding head 86 on the main grinding ball 84 rotates alternately with the large grinding head 83 area in the material distribution chamber 82 at this position, and the soybean particles in the material distribution chamber 82 where the main grinding ball 84 is located are ground in different areas. When the soybean particles in the material distribution chamber 82 where the main grinding ball 84 is located reach the material distribution chamber 82 where the auxiliary grinding ball 85 is located, similarly, the planetary gear 75 drives the auxiliary grinding ball 85 to grind the soybean particles in the material distribution chamber 82 through the rotating rod 76, and so on, until the soybean particles in the material distribution chamber 82 are fully ground and then discharged from the two rows of discharge pipes 17.

[0056] It should be noted that the specific model and specifications of the servo motor 61 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0057] The power supply circuit of the servo motor 61 is clear to those skilled in the art and will not be described in detail here.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
