[0045] Combine Figure 1 and Figure 2 As shown, the material grinding device provided by the embodiment of the present disclosure includes a material conveying component 1, a material crushing component 2, a material grinding component 3 and a screening component 4.

[0046] The material conveying assembly 1 conveys material toward the material crushing assembly 2, which crushes the incoming material. The bottom of the material crushing assembly 2 is equipped with a discharge hole group 21 for discharging the crushed material. Once the crushed material reaches a certain size, it can be discharged downward through the discharge hole group 21. The material flowing out of the discharge hole group 21 enters the material grinding assembly 3, which grinds the incoming material. The screening assembly 4 receives the material conveyed by the material grinding assembly 3 and is configured to convey the qualified material to the target location.

[0047] The material grinding device provided by the present disclosure crushes the material before grinding by setting a material crushing component 2, and limits the size of the material discharged from the material crushing component 2 through the discharge hole group 21, so as to reduce the size of the material entering the material grinding component 3, increase the grinding efficiency of the material grinding component 3, and thus increase the working efficiency of the entire material grinding device, and limit the size of the material discharged from the material grinding component 3 through the screening component 4, so that the output material size meets the demand, thereby increasing the effect of the finished material.

[0048] In some embodiments, the material in the present application is camellia seeds, that is, the material grinding device is used to grind the camellia seeds, thereby increasing the grinding efficiency and the finished product effect of the camellia seeds and ensuring that the camellia seed particles are uniform and fine.

[0049] In some embodiments, as Figure 2 As shown, the material conveying assembly 1 includes a conveying cylinder 11 , a conveying auger 12 and an auger motor 13 .

[0050] The conveying cylinder 11 is extended in the vertical direction. The vertical direction here can be perpendicular to the horizontal plane or have a certain angle with the horizontal plane, and can be designed according to actual needs. The conveying auger 12 is rotatably arranged in the conveying cylinder 11, and the conveying auger 12 is coaxially arranged with the conveying cylinder 11. The auger motor 13 is used to drive the conveying auger 12 to rotate. Specifically, the conveying cylinder 11 is supported by a fixed frame (not shown in the figure), and the auger motor 13 is arranged at the bottom of the conveying cylinder 11. The output shaft of the auger motor 13 is coaxially arranged with the conveying auger 12 and can drive the conveying auger 12 to rotate, so that the conveying auger 12 can lift the material upward in the vertical direction. A discharge port is provided at the top of the conveying cylinder 11, and the material output through the discharge port of the conveying cylinder 11 can enter the material crushing assembly 2.

[0051] The material conveying assembly 1 in this design adopts a lifting method to convey the material, so that the conveyed material is at a certain height from the ground, which is convenient for subsequent crushing and grinding operations of the material.

[0052] In some embodiments, the material grinding device further includes a feed box 5 disposed above the material crushing assembly 2. The feed port of the feed box 5 is connected to the discharge port of the conveying cylinder 11 via a first conveying plate 6. The end of the first conveying plate 6 connected to the feed port of the feed box 5 is tilted downward so that the material conveyed by the material conveying assembly 1 can be conveyed into the material crushing assembly 2 via the first conveying plate 6. The feed box 5 is used to convey material toward the material crushing assembly 2. That is, a discharge port is provided at the bottom of the feed box 5, and the discharge port of the feed box 5 is connected to the feed port of the material crushing assembly 2, thereby facilitating the conveyance of the material.

[0053] In this design, by setting up a feed box 5 for temporarily storing materials, it is convenient to control the material feeding amount, thereby ensuring the subsequent crushing and grinding effect of the material, and avoiding the problem of incomplete material crushing due to excessive material feeding.

[0054] In some embodiments, a valve is provided at the discharge port of the feed box 5, and the material supply or suspension of delivery can be achieved by opening or closing the valve, thereby facilitating the control of the material delivery amount.

[0055] In some embodiments, the material crushing assembly 2 includes a crushing drum 22 , a rotating part, and a crushing part.

[0056] The crushing drum 22 is located below the feed box 5 and receives material conveyed through the feed box 5. The rotating element includes a shaft 23 horizontally disposed within the crushing drum 22 and a crushing motor 24 that drives the shaft 23. The crushing element comprises multiple crushing rollers 25 disposed around the shaft 23. A discharge hole group 21 is provided at the bottom of the crushing drum 22.

[0057] During operation, the crushing motor 24 drives the rotating shaft 23 to rotate at high speed, which in turn drives the multiple crushing rollers 25 on the rotating shaft 23 to rotate at high speed. When the material enters the crushing drum 22, it will come into contact with the crushing rollers 25 and be crushed by the crushing rollers 25. At this time, the material that meets the standards will flow out through the discharge hole group 21 and enter the next process for grinding. The material that does not meet the standards will continue to be beaten by the crushing rollers 25 in the crushing drum 22 until the size is achieved.

[0058] Under this design, the crushing effect is increased by using multiple rotating crushing rollers 25 to crush the material, and the discharge hole group 21 can allow qualified materials to pass through, reducing the size of the material entering the subsequent material grinding component 3, thereby increasing the grinding effect of the material grinding component 3.

[0059] In some embodiments, the discharge hole group 21 includes a plurality of discharge holes evenly distributed on the bottom of the crushing drum 22 to increase the discharge effect while preventing uncrushed materials from passing through.

[0060] In some embodiments, multiple crushing rollers 25 are staggered to further increase the impact and crushing efficiency of the material.

[0061] In some embodiments, as Figure 2 As shown, the material grinding assembly 3 includes a grinding box 31 , a grinding plate 32 and a grinding motor 33 .

[0062] A grinding box 31 is positioned below the crushing drum 22 to receive material discharged through the discharge hole group 21. A grinding plate 32 is tilted within the grinding box 31, allowing material discharged through the discharge hole group 21 to enter the grinding plate 32. A grinding motor 33 is used to vibrate the grinding plate 32, causing it to grind the material.

[0063] During operation, the material crushed by the material crushing assembly 2 passes through the discharge hole group 21 into the grinding box 31 and falls into the grinding plate 32. Among them, the grinding plate 32 includes a fixed plate and a vibration plate arranged in the grinding box 31. The vibration plate is arranged above the fixed plate, and the vibration plate and the fixed plate are spaced apart and have a certain inclination angle to facilitate the introduction of materials. The grinding motor 33 is arranged on the vibration plate to be able to drive the vibration plate to vibrate. The fixed plate and / or the vibration plate are provided with a plurality of sharp protrusions. The sharp protrusions are made of wear-resistant material to increase the service life. The material entering between the vibration plate and the fixed plate moves downward along the slope of the fixed plate. During this process, the grinding motor 33 drives the vibration plate to vibrate, thereby realizing the grinding of the material during the sliding process to ensure the grinding effect.

[0064] In some embodiments, combined Figure 1 and Figure 2As shown, a pouring plate 34 is obliquely provided in the grinding box 31 . The pouring plate 34 is arranged below the discharge hole group 21 , and the bottom of the pouring plate 34 is connected to the feed port of the grinding plate 32 .

[0065] Under this design, the material discharged through the discharge hole group 21 falls onto the pouring plate 34 and slides along the slope surface of the pouring plate 34 to the feed port position of the grinding plate 32, specifically between the vibrating plate and the fixed plate of the grinding plate 32, to ensure the stability of material transportation.

[0066] In some embodiments, the grinding plate 32 is located below the pouring plate 34 . In this case, the inclination direction of the grinding plate 32 is opposite to the inclination direction of the pouring plate 34 to reduce space occupation in the horizontal direction.

[0067] In some embodiments, the screening assembly 4 includes a screening box 41 and a screening plate 42 .

[0068] The screening box 41 is arranged below the grinding box 31 so that the ground material can fall into the screening box 41. The screening plate 42 is arranged at an angle in the screening box 41 so that the material outputted by the grinding plate 32 can fall onto the screening plate 42. The screening plate 42 is provided with a plurality of screening holes, through which the material that meets the size requirements can flow to the target location.

[0069] Under this design, materials that meet the size requirements can be screened through the screening plate 42 to ensure that the output materials can meet the needs.

[0070] In some embodiments, the screening assembly 4 also includes a return grinding guide plate 43 obliquely arranged in the screening box 41, the top of the return grinding guide plate 43 is connected to the bottom end of the screening plate 42, and the bottom end of the return grinding guide plate 43 is connected to the material conveying assembly 1, wherein the bottom end of the return grinding guide plate 43 and the material conveying assembly 1 are connected through a second conveying plate 7.

[0071] Under this design, materials that do not meet the size requirements are re-conveyed into the material conveying assembly 1 through the return grinding guide plate 43 and the second conveying plate 7, so that this part of the material goes through the crushing and grinding stage again along with the introduced material to meet the size requirements.

[0072] In some embodiments, as Figure 2 As shown, the screening assembly 4 also includes a feed plate 44 obliquely arranged in the screening box 41, and the feed plate 44 is located below the screening plate 42, wherein a discharge port is provided at the bottom of the screening box 41, and the bottom end of the feed plate 44 faces the discharge port.

[0073] In this design, the conveying plate is provided to guide the conveying of the qualified materials, thereby ensuring that the qualified materials can flow out to the target position through the discharge port of the screening box 41 .

[0074] In some embodiments, as Figure 2 As shown, the screening assembly 4 further includes a vibration motor 45 disposed on the screening plate 42 , wherein the vibration motor 45 is disposed at the bottom of the screening plate 42 .

[0075] In this design, the vibration motor 45 can provide high-frequency vibration for the screening plate 42, ensuring that qualified materials can quickly pass through the screening plate 42, thereby increasing the screening effect of the materials.
