DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] The grain grinding device disclosed in the present invention is mainly used in the scenario of fine grinding of a large amount of grains.

[0028] Reference Figures 1 to 8 , a grain milling device, comprising a machine body 1, inside of which is arranged a primary processing mechanism 2 for synchronously milling a large amount of grains at one time; The primary processing mechanism 2 is provided with a secondary processing mechanism 3 for performing multi-stage grinding and fine processing on the grains; The outer side of the machine body 1 is provided with a material distribution mechanism 4 for evenly distributing and feeding the grains; A large amount of grains are evenly spread and transported to the interior of the primary processing mechanism 2 through the material leveling mechanism 4. The primary processing mechanism 2 is used to grind a large amount of grains synchronously, and then the secondary processing mechanism 3 is used to perform multi-level fine processing on the initially grinded grains, thereby improving the grain grinding output and quality.

[0029] In this embodiment: the user puts the grains that need to be ground into the material distribution mechanism 4, and starts the material distribution mechanism 4 at the same time. The material distribution mechanism 4 will layer a large amount of grains and intermittently introduce them into the interior of the primary processing mechanism 2. At the same time, the primary processing mechanism 2 is started to grind the grains. While the primary processing mechanism 2 is working, the secondary processing mechanism 3 will operate synchronously. The grains preliminarily ground by the primary processing mechanism 2 will continue to fall downward and fall into the interlayer between the secondary processing mechanism 3 and the machine body 1. As the secondary processing mechanism 3 runs, the fallen grains will be ground for a second and multiple times to improve the fineness, and finally fall out from the bottom of the machine body 1 to complete the processing of the grains.

[0030] It should be additionally explained that a discharge port 6 is provided through the bottom of the machine body 1 , and the processed fine grain products can be discharged from the inside of the machine body 1 through the discharge port 6 .

[0031] In the above scheme, in order to improve the working efficiency of the traditional grinding device, a large amount of grains can be ground at the same time, and the specific operations are as follows.

[0032] Reference Figures 1 to 8In a preferred embodiment, the primary processing mechanism 2 includes a motor 201 vertically fixed to the top of the machine body 1, and the output end of the motor 201 vertically penetrates into the interior of the machine body 1. A first-class moving rolling disc 202 and a plurality of evenly distributed second-class moving rolling discs 203 are sleeved and fixed to the outer side of the output end of the motor 201. The first-class moving rolling disc 202 is distributed on the top of the second-class moving rolling disc 203. At the same time, a plurality of evenly distributed fixed rolling discs 204 are evenly fixed in the vertical direction inside the machine body 1. The output shaft of the motor 201 vertically penetrates the middle of the plurality of fixed rolling discs 204, and the first-class moving rolling disc 202, the second-class moving rolling disc 203 and the fixed rolling disc 204 are interspersed in the vertical direction.

[0033] In this embodiment: the user puts the grains to be ground into the material distribution mechanism 4 and starts the material distribution mechanism 4 at the same time. The material distribution mechanism 4 will layer a large amount of grains and intermittently introduce them into the interior of the first type of movable grinding disc 202 and the fixed grinding disc 204, so that the grains are distributed between the bottom of the first type of movable grinding disc 202 and the top layer of the fixed grinding disc 204, and between the second type of movable grinding disc 203 and the bottom layer of the fixed grinding disc 204. At this time, the motor 201 rotates, and drives the first type of movable grinding disc 202 and all the second type of movable grinding discs 203 to rotate synchronously through the output shaft, and cooperates with the stationary fixed grinding disc 204 to grind the grains into granules and powder. The ground grains will gradually move to a position away from the output axis of the motor 201, and finally fall downward.

[0034] In the above scheme, in order to improve the fineness of the grains after preliminary grinding and improve the quality of the finished grains, the grains are subjected to multi-stage grinding, and the specific operations are as follows.

[0035] Reference Figures 2 to 5 , Figure 7 In a preferred embodiment, the reprocessing mechanism 3 includes a plurality of arc grooves 301 evenly opened on the outside of each fixed rolling disc 204, and a rolling ring 302 is fixedly sleeved on the outside of each second-class movable rolling disc 203, and the rolling ring 302 is close to the inner wall of the machine body 1, and a plurality of anti-blocking sections 303 evenly distributed in the vertical direction are opened on the inner wall of the machine body 1, and two adjacent anti-blocking sections 303 are staggered in the horizontal direction, and each rolling ring 302 corresponds to an anti-blocking section 303 in the horizontal direction.

[0036] In this embodiment: the ground grains will gradually move to a position away from the output axis of the motor 201, and finally fall downward through the arc groove 301, and fall into the interlayer between the outer ring 302 of the second-class dynamic grinding disc 203 and the machine body 1 of the next layer. At this time, the ring 302 rotates synchronously with the rotation of the second-class dynamic grinding disc 203, and grinds the fallen grains again, making the grains more finely divided and continue to fall from the interlayer between the ring 302 and the machine body 1, and some of the grains accumulated on the top of the ring 302 will be synchronously displaced with the rotation of the ring 302 until the grains reach the side end of the anti-blocking interval 303. At this time, the grains lose the extrusion restriction and fall downward from the inside of the anti-blocking interval 303 to the next layer, thereby preventing the grains from accumulating; in this reciprocating manner, the fine grinding of the grains is completed.

[0037] In the above scheme, in order to allow the grain to be more evenly distributed between the bottom of the first type of movable grinding plate 202 and the top layer of the fixed grinding plate 204, and between the second type of movable grinding plate 203 and the bottom layer of the fixed grinding plate 204, and to improve the working quality of the equipment, the specific operations are as follows.

[0038] Reference Figures 1 to 3 , Figures 7 and 8 In a preferred embodiment, the material balancing mechanism 4 includes a turntable 401 rotatably mounted on the top side end of the body 1, a bidirectional screw rod 402 is vertically fixed on the top of the turntable 401, a belt 403 is transmission-connected between the turntable 401 and the output shaft of the motor 201, an L-shaped plate 404 is threadedly connected to the outer side of the bidirectional screw rod 402, a circular groove 405 is penetrated through the inside of the L-shaped plate 404 in the horizontal direction, the number of the circular grooves 405 is several and evenly distributed in the vertical direction, a first feed pipe 406 is through-connected to the side end of each fixed grinding disc 204, the first feed pipe 406 penetrates from the inside of the body 1, several first feed pipes 406 and several circular grooves 405 are staggered, and a material balancing table 407 is squeezed and fitted on the side end of the L-shaped plate 404, and the material balancing table 407 is fixedly connected to the side end of the body 1.

[0039] In this embodiment: the user puts the grains that need to be ground into the material distribution table 407; when the motor 201 starts to rotate, the belt 403 will drive the turntable 401 to rotate, and the rotating turntable 401 will drive the bidirectional screw rod 402 to rotate synchronously, and the rotating bidirectional screw rod 402 will drive the L-shaped plate 404 to continuously move up and down through the thread, so that the several circular grooves 405 located at the side end of the L-shaped plate 404 are intermittently connected with the first feed pipe 406 and the material distribution table 407. The grains inside the material distribution table 407 are evenly passed through the circular grooves 405 and the first feed pipe 406 into the interior of the first type of movable grinding disc 202 and the fixed grinding disc 204, so that the grains are distributed between the bottom of the first type of movable grinding disc 202 and the top interlayer of the fixed grinding disc 204, and between the bottom interlayer of the second type of movable grinding disc 203 and the fixed grinding disc 204.

[0040] It should be additionally explained that a feeding hopper 408 is vertically fixed on the top of the material-distributing platform 407 , and the feeding hopper 408 is connected to the inside of the material-distributing platform 407 , so that the user can add materials to the inside of the material-distributing platform 407 .

[0041] In the above scheme, considering that the grains located between the bottom layer of the second type moving grinding plate 203 and the fixed grinding plate 204 need space to fall to the lower layer, the specific operation is as follows.

[0042] Reference Figure 7 In a preferred embodiment, a material discharge chute 304 is vertically provided between the connection between the second type of movable rolling disc 203 and the rolling ring 302.

[0043] In this embodiment, the grains located between the bottom layer of the second type moving grinding disc 203 and the fixed grinding disc 204 will gradually move to a position away from the output axis of the motor 201 , and finally fall downward through the discharge chute 304 .

[0044] In the above scheme, in order to ensure that a type of moving grinding disc 202 can also perform grinding work, the specific operation is as follows.

[0045] Reference Figures 2 to 5 , Figure 7 In a preferred embodiment, a feed channel 410 is provided inside the connection between the output shaft of the motor 201 and a type of dynamic rolling disc 202, and a second feed pipe 409 is horizontally distributed on the side end of the output shaft of the motor 201. A connecting portion 411 is rotatably sleeved on the outer side of the output shaft of the motor 201, and the connecting portion 411 is respectively connected to the second feed pipe 409 and the feed channel 410.

[0046] In this embodiment: when the plurality of circular grooves 405 located at the side end of the L-shaped plate 404 are connected to the second feed pipe 409, the grains located inside the material balancing table 407 will enter the interior of the feed channel 410 through the second feed pipe 409 and the adapter 411, and enter the interlayer between the bottom of a type of movable grinding disc 202 and the top of the fixed grinding disc 204 through the feed channel 410.

[0047] In the above solution, in order to facilitate the user to observe the operation status inside the body 1 and make adjustments, the specific operations are as follows.

[0048] Reference Figure 1 In a preferred embodiment, a glass window 5 is embedded on the outer side of the body 1 .

[0049] In this embodiment: when the device is running, the user can observe the operation status inside the body 1 in real time through the glass window 5 so as to make adjustments.

[0050] Working principle: When in use, the user puts the grains to be ground into the material distribution table 407; when the motor 201 starts to rotate, it will drive the turntable 401 to rotate through the belt 403, and the rotating turntable 401 will drive the bidirectional screw rod 402 to rotate synchronously, and the rotating bidirectional screw rod 402 will drive the L-shaped plate 404 to move up and down continuously through the thread, so that the several circular grooves 405 at the side end of the L-shaped plate 404 intermittently contact with the first inlet. The feed pipe 406 and the material distribution platform 407 are connected, so that the grains inside the material distribution platform 407 are uniformly passed through the circular groove 405 and the first feed pipe 406 into the first type of movable grinding disc 202 and the fixed grinding disc 204, so that the grains are distributed between the bottom of the first type of movable grinding disc 202 and the top interlayer of the fixed grinding disc 204, and between the second type of movable grinding disc 203 and the bottom interlayer of the fixed grinding disc 204. At this time, the motor 201 rotates, driving the first type of movable grinding disc 202 and all the second type of movable grinding discs 203 through the output shaft. The movable grinding disc 203 rotates synchronously, cooperating with the stationary fixed grinding disc 204 to grind the grains into granules and powders. The ground grains will gradually move toward a position away from the output axis of the motor 201, and finally fall downwards and fall into the interlayer between the outer grinding ring 302 of the second type movable grinding disc 203 and the machine body 1 of the next layer. At this time, the grinding ring 302 rotates synchronously with the rotation of the second type movable grinding disc 203, and grinds the fallen grains again, making the grains more finely broken and continue to fall from the interlayer between the grinding ring 302 and the machine body 1. The grains partially accumulated on the top of the grinding ring 302 will be synchronously displaced with the rotation of the grinding ring 302 until the grains reach the side end of the anti-blocking interval 303. At this time, the grains lose the extrusion restriction and fall downwards from the inside of the anti-blocking interval 303 to the next layer, thereby preventing the grains from accumulating. This reciprocating process completes the fine grinding of the grains, and finally the fine grain products are discharged from the bottom of the machine body 1, completing the entire workflow.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
