Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a feed additive raw material crushing device. Background Technology

[0002] Feed additives are substances added in small amounts to compound feed to meet specific purposes, usually at a level ≤1%. These additives may be used to supplement essential nutrients (such as vitamins, amino acids, and minerals), improve feed quality (antifungal agents, antioxidants), promote digestion and absorption (enzyme preparations, acidifiers), regulate intestinal health (probiotics, oligosaccharides), or enhance the quality of animal products (coloring agents). Existing feed additives are classified into crystalline solids, powders, fibrous forms, liquids / viscous substances, and granules.

[0003] A crushing device is a mechanical device used to break large materials into small particles or powders. It reduces the geometric size of materials by external force (such as impact, shearing, friction, etc.). When crushing raw materials for feed additives, solid particles such as crystalline solids or granules are generally crushed by grinding with a grinding wheel and a fixed grinding surface to achieve ultrafine crushing so that feed additives can be mixed evenly with other materials. However, during the crushing process, when the grinding wheel and the fixed grinding surface are crushing, the grinding wheel generally rotates in one direction, which causes the crushed material to easily form thin flaky particles along a certain plane, affecting the crushing effect.

[0004] Therefore, we propose a feed additive raw material grinding device. Utility Model Content

A feed hopper 8 is provided above the upper crushing chamber 7, and a fixed grinding surface 4 is fixedly connected to the upper crushing chamber 7. A grinding wheel 3 is provided on the inner side of the fixed grinding surface 4. This utility model uses a secondary vibration crushing mechanism fixedly connected inside the lower crushing chamber. The secondary vibration crushing mechanism includes a guide frame, an outer crushing impeller, an inner crushing impeller, a bearing, a support plate, a bevel gear, a spring, a sliding block, and an elliptical drive block. During the processing, it can further crush the already crushed flaky materials. At the same time, the sliding block can intermittently vibrate to clean the inner wall and surface of the holes in the support plate, providing a crushing effect.

[0026] Furthermore, the secondary vibration crushing mechanism 9 includes a guide frame 901, an outer crushing impeller 902, an inner crushing impeller 903, a bearing 904, a support plate 905, a bevel gear 906, a spring 907, a sliding block 908, and an elliptical drive block 909. The guide frame 901 is fixedly connected to the discharge port of the lower crushing chamber 6, and the guide frame 901 is fixedly connected to the support plate 905. The outer crushing impeller 902 is located above the support plate 905, and the inner crushing impeller 903 is located above the outer crushing impeller 902. The crushed material can be guided by the inclined surface opened on the inner side of the guide frame. At the same time, a connecting ring is fixedly connected inside the guide frame to ensure the stability of the support plate, so that the secondary vibration crushing mechanism can operate stably.

[0027] Furthermore, one end of the outer crushing impeller 902 is fixedly connected to the outer ring of the bearing 904, the inner crushing impeller 903 connecting rod is fixedly connected inside the bearing 904, the middle of the outer crushing impeller 902 is fixedly connected to the elliptical drive block 909, and the outer crushing impeller 902 is fixedly connected to the bevel gear 906. The bevel gear 906 is connected to the power transmission mechanism 5. By fixing the outer crushing impeller to the elliptical drive block and the bevel gear, it is ensured that the elliptical drive block can intermittently generate whole particles, ensuring the flow of materials. At the same time, the outer crushing impeller and the inner crushing impeller rotate in opposite directions, thereby ensuring the effective dispersal of flaky materials.

[0028] Furthermore, the outer crushing impeller 902 is internally rotatably connected to the inner crushing impeller 903. One end of the inner crushing impeller 903 is fixedly connected to the bevel gear 906. The bevel gear 906 is connected to the power transmission mechanism 5. Through the mutual transmission between multiple bevel gears, and at the same time, one of the bevel gears is fixedly connected to the auxiliary transmission rod, thereby ensuring the stability of the transmission power so that the outer crushing impeller and the inner crushing impeller can rotate.

[0029] Furthermore, a conical protective cover 910 for protecting the bevel gear 906 is connected below the support plate 905. The conical protective cover 910 is rotatably connected to the power transmission mechanism 5. The support plate 905 has holes. The conical protective cover can effectively protect the stability of the meshing of multiple bevel gears. At the same time, a hole is opened on one side of the conical protective cover, and a rubber buffer pad is installed in the hole to reduce the impact of vibration on the auxiliary transmission rod.

[0030] Furthermore, the conical protective cover 910 has two springs 907 on its inner side. The conical protective cover 910 is slidably connected to a sliding block 908. The sliding block 908 tightly presses against the springs 907. The sliding block 908 intermittently engages with an elliptical drive block 909. A support arm is provided on the inner side of the conical protective cover for the sliding block to move back and forth. At the same time, the spring inside the support arm can tightly press against the sliding block, causing the sliding block to vibrate when it resets.

[0031] Furthermore, the power transmission mechanism 5 comprises a main drive disc 501, a belt 502, a secondary drive disc 503, a drive shaft 504, a drive shaft bearing 505, an auxiliary large drive disc 506, a second belt 507, an auxiliary small drive disc 508, an auxiliary transmission rod 509, and an auxiliary transmission rod base 510. The main drive disc 501 is fixedly connected to the output shaft of the motor 1, and the main drive disc 501 is driven by the belt 502. The belt 502 is driven by the secondary drive disc 503, and the secondary drive disc 503 is fixedly connected to one end of the drive shaft 504. Both ends of the drive shaft 504 are equipped with drive shaft bearings 505. The other end of the drive shaft 504 is fixedly connected to the auxiliary large drive disk 506. The auxiliary large drive disk 506 is connected to the second belt 507. The second belt 507 is connected to the auxiliary small drive disk 508.

One end of the auxiliary transmission rod 509 is fixedly connected to the bevel gear 906. Through the power transmission mechanism, the stability of the motor's power transmission is ensured, thus making its processing stable.

[0032] In this solution, the workflow is as follows: First, feed raw materials, such as crystalline solids, are fed into the upper crushing chamber 7 through the feed hopper 8. After the motor 1 starts, the output shaft drives the main drive disk 501 to rotate. The power is transmitted to the auxiliary drive disk 503 through the belt 502. The drive shaft 504 rotates under the support of the drive shaft bearing 505, and drives the grinding wheel 3 to rotate. The grinding wheel 3 generates shearing and extrusion forces with the fixed grinding surface 4, crushing the raw materials into coarse particles. At the same time, the auxiliary large drive disk 506 connected to the end of the drive shaft drives the auxiliary small drive disk 508 to rotate through the belt 2 507. Finally, the auxiliary transmission rod 509 is driven to rotate at high speed on the auxiliary transmission rod base 510.

[0033] When the drive auxiliary transmission rod 509 rotates, it drives the bevel gear 906 to rotate. The bevel gear 906 drives or drives the outer crushing impeller 902 and the inner crushing impeller 903 to rotate in opposite directions: the outer crushing impeller rotates clockwise and the inner crushing impeller rotates counterclockwise, forming a counter-shearing effect, which can process multi-piece materials again. At the same time, the elliptical drive block 909 will push the sliding block 908 to reciprocate along the guide frame 901 during the rotation of the outer crushing impeller 902. The compression spring 907 generates high-frequency vibration to guide the material through vibration.
