[0002] Raw materials refer to materials that have not undergone processing or manufacturing, such as mineral products and agricultural products. Materials used for further processing are raw materials, which can be products of other processing processes or products that grow or form naturally in nature. Agricultural raw materials, such as hard raw materials like soybeans, are often processed into powder. In order to make soybean powder more delicate, fine grinding machines are often used to finely grind raw materials such as soybeans.

[0003] Existing fine grinding machines typically involve pouring hard raw materials such as soybeans into a container, using rollers and other devices to continuously grind the raw materials, and then filtering the ground powder through a special filter screen to ensure that the powder meets the requirements of fine grinding.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a raw material refining mill. (Refer to...) Figure 2 Figure 3 A raw material grinding mill includes a grinding chamber 1, a plurality of support legs 2 fixedly connected to the bottom of the grinding chamber 1, and a grinding filter screen 3 fixedly connected to the inner bottom of the grinding chamber 1.

[0025] The multi-purpose fine grinding mechanism 4 is located in the middle of the inner wall of the fine grinding box 1, and is used for multi-functional processing of hard raw materials;

[0026] The impurity removal mechanism 8 is located on the inner wall of the fine grinding box 1 and above the multi-purpose fine grinding mechanism 4, for quickly filtering and removing impurities from the raw materials.

[0027] The multi-purpose fine grinding mechanism 4 includes a motor 401, a roller 402, a grinding unit 5, a crushing unit 6, and an anti-sticking unit 7. The motor 401 is fixedly connected to the middle of the side wall of the fine grinding box 1, and the roller 402 is rotatably connected to the middle of the inner wall of the fine grinding box 1. The output end of the motor 401 rotates through the side wall of the fine grinding box 1 and is fixedly connected to one end of the roller 402. The grinding unit 5, the crushing unit 6, and the anti-sticking unit 7 are respectively installed on the side wall of the roller 402.

[0028] The grinding unit 5 includes a grinding roller 501 and two first support frames 502. One end of the two first support frames 502 is fixedly connected to the side wall of the roller 402, and the grinding roller 501 is rotatably connected between the two first support frames 502.

[0029] The crushing unit 6 includes two second support frames 601, two limiting grooves 602, two cylinders 603, two sliders 604, a striking block 605, and two first springs 606. One end of each of the two second support frames 601 is fixedly connected to the side wall of the roller 402. The two limiting grooves 602 are respectively opened on the side walls of the two second support frames 601. The two cylinders 603 are respectively fixedly connected to one end of each of the two limiting grooves 602. The two ends of the striking block 605 are slidably connected to the side walls of the two limiting grooves 602 through the two sliders 604. One end of each slider 604 is fixedly connected to the output end of each of the two cylinders 603. The two ends of each of the two first springs 606 are respectively fixedly connected to one end of each of the two limiting grooves 602 and the other end of each slider 604.

[0030] The anti-sticking unit 7 includes a fixing plate 701, a number of second springs 702 and a brush plate 703. One end of the fixing plate 701 is fixedly connected to the side wall of the roller 402, and one end of the brush plate 703 is elastically connected to the inner side of the other end of the fixing plate 701 through a number of second springs 702.

[0031] In this embodiment, the raw material is first poured into the fine grinding box 1. Impurities are filtered and screened by the impurity removal mechanism 8. Then, the motor 401 is activated to provide force, driving the roller 402 to rotate inside the fine grinding box 1. The rotation of the roller 402 causes the second support frame 601 to rotate accordingly. The cylinder 603 is activated to provide force, causing two sliders 604 to slide back and forth within two limiting grooves 602. The sliding movement of the two sliders 604 causes the striking block 605 to move back and forth between the two second support frames 601. The back-and-forth movement of the striking block 605 strikes and beats the raw material particles, causing them to break down quickly. Simultaneously, the first spring 606 buffers and absorbs the counter-vibration force, thus protecting the overall structure. In this way, the second support frame 601, following the rotation of the roller 402, drives the striking block 605 to rotate simultaneously... The raw materials are first crushed by hammering, and then the first support frame 502 rotates as the roller 402 rotates. The first support frame 502 rotates as the grinding roller 501 rotates, which in turn further grinds the crushed raw materials into powder. The rotation of the roller 402 also drives the fixed plate 701 to rotate, and the second spring 702 provides force to make the brush plate 703 extend from the inner side of one end of the fixed plate 701 and stick to the inner wall of the fine grinding box 1. The rotation of the roller 402 drives the brush plate 703 to rotate and clean the powdered raw materials, sending the powder to the fine grinding filter 3 for filtration. This cycle is repeated to achieve multiple functions of crushing, grinding and anti-sticking cleaning of hard raw materials, thereby effectively improving the grinding efficiency of hard raw materials.

[0032] Furthermore, the impurity removal mechanism 8 includes an impurity removal filter plate 801, a vibrating plate 802, a vibrating motor 803, and two buffer components 9. The bottom of the impurity removal filter plate 801 is installed on the inner wall of the fine grinding box 1 through the two buffer components 9. The vibrating plate 802 is fixedly connected to the bottom center of the impurity removal filter plate 801, and the vibrating motor 803 is fixedly connected to the bottom of the vibrating plate 802.

[0033] The buffer assembly 9 includes a support plate 901, a buffer slide bar 902, and a third spring 903. The side wall of the support plate 901 is fixedly connected to the inner wall of the fine grinding box 1, the bottom of the buffer slide bar 902 is fixedly connected to the top of the support plate 901, the bottom of the impurity removal filter plate 801 is slidably connected to the side wall of the buffer slide bar 902, and the two ends of the third spring 903 are respectively fixedly connected to the top of the support plate 901 and the bottom of the impurity removal filter plate 801.

[0034] Based on the above embodiments, when impurities are filtered by the impurity removal mechanism 8, the vibration motor 803 is activated to provide force to drive the vibration plate 802 to vibrate. The vibration of the vibration plate 802 drives the impurity removal filter plate 801 to vibrate. In this way, the impurities mixed in with the raw material can be quickly filtered and separated by the impurity removal filter plate 801 during vibration. At the same time, the impurity removal filter plate 801 slides on the buffer slide bar 902 due to vibration, and the third spring 903 provides a reaction force to buffer and absorb the vibration force, thereby providing buffer protection for the fine grinding box 1, and thus achieving the effect of facilitating the filtration and removal of impurities in the raw material.

[0035] The implementation principle of a raw material grinding mill according to an embodiment of this application is as follows: In use, the raw material is first poured into the grinding chamber 1. The vibration motor 803 is activated, providing force to drive the vibrating plate 802 to vibrate. The vibration of the vibrating plate 802, in turn, drives the impurity removal filter plate 801 to vibrate. Thus, the vibration of the impurity removal filter plate 801 allows the raw material to pass through the filter plate 801 quickly, separating and filtering out impurities. Simultaneously, the impurity removal filter plate 801 slides on the buffer slide rod 902, and the third spring 903 provides a reaction force to buffer and absorb the vibration force. The grinding chamber 1 provides buffer protection, thereby effectively facilitating the filtration and removal of impurities from the raw materials and preventing impurities from affecting subsequent grinding processes. After filtration and removal, the raw materials fall to the bottom of the grinding chamber 1. The motor 401, when activated, provides force to drive the roller 402 to rotate inside the grinding chamber 1. The rotation of the roller 402 causes the second support frame 601 to rotate accordingly. The cylinder 603, when activated, provides force to drive the two sliders 604 to slide back and forth within the two limiting grooves 602. The sliding movement of the two sliders 604 causes the striking blocks 605 to move back and forth within the two limiting grooves 602. The support frames 601 move back and forth, and the striking blocks 605 move back and forth to strike and beat the raw material particles, causing the raw material to be crushed quickly. At the same time, the first spring 606 buffers and absorbs the shock force, thus protecting the overall structure. In this way, the second support frame 601 rotates with the roller 402, driving the striking blocks 605 to crush the raw material while rotating. Then, the rotation of the roller 402 drives the first support frame 502 to rotate as well. The rotation of the first support frame 502 causes the grinding roller 501 to rotate as well. Thus, the rotation of the grinding roller 501 can grind the crushed raw material. The material is further crushed and ground into powder. The rotation of the roller 402 also drives the fixed plate 701 to rotate. The second spring 702 provides force to make the brush plate 703 extend from the inner side of one end of the fixed plate 701 and stick to the inner wall of the fine grinding box 1. In this way, the rotation of the roller 402 drives the brush plate 703 to rotate and clean the crushed material. The powder is swept to the fine grinding filter screen 3 for filtration. This cycle is repeated to achieve multiple functions such as crushing, grinding and anti-sticking cleaning of hard materials, thereby effectively improving the grinding efficiency of hard materials.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
