[0020] 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 of the embodiments.

[0021] In this embodiment, refer to Figure 1-3 A grinding device for bio-based material research and development includes a grinding jar 1. A feeding port 2 is arranged on the top of the grinding jar 1. The grinding jar 1 is suspended in the air by supporting legs 5 arranged at the bottom thereof. A grinding mechanism is arranged inside the grinding jar 1. Discharging mechanisms are arranged on both the front and rear sides of the outside of the grinding jar 1. The grinding mechanism and the discharging mechanism are driven coaxially through the same transmission shaft.

[0022] Specifically explain the structure of the grinding mechanism and the discharging mechanism, and combine the attached Figure 2 It can be seen that the grinding mechanism includes a grinding roller 3, which rotates with its roller surface eccentric axis as the axis. In addition, the grinding jar 1 is designed as a jar body with a semi-elliptical cross-section, and the eccentric axis of the grinding roller 3 is set on the vertical center axis of the grinding jar 1.

[0023] The bio-based material to be ground is poured into the grinding tank 1 through the feed port 2, and the grinding roller 3 periodically contacts the inner wall of the grinding tank 1 during the rotation process, thereby extruding and grinding the bio-based material to accelerate the material refinement. It should also be noted that a material outlet is provided at the bottom of the grinding tank 1, and a double-opening baffle is provided inside the material outlet. The grinding tank 1 is also provided with a temporary storage trough 4 at the bottom of its material outlet. The main function of the temporary storage trough 4 is to provide a conveying channel for the material to ensure that the material can fall down smoothly.

[0024] The opening and closing states of the double-opening baffle are relatively independent, and a separate switch can be used to control the opening and closing thereof. In the normal grinding state, the double-opening baffle is in a closed state. When the grinding is completed, the baffle is opened, and the materials of the batch first fall into the temporary storage trough 4 below.

[0025] Combined with Figure 1It can be seen that the discharging mechanism includes a rotating disc 11, a half gear 13, a discharging bottom plate 6, a sliding column 8 and a collecting box 9. The rotation center of the rotating disc 11 is coaxial with the rotation center of the grinding roller 3, and a motor for driving the grinding roller 3 and the rotating disc 11 to rotate synchronously is arranged outside the grinding tank 1. The internal grinding roller 3 and the external rotating disc 11 can be driven by an external motor to rotate simultaneously.

[0026] The half gear 13 is arranged directly below the rotating disk 11. An integral extension arm 14 is arranged on the top of the half gear 13. A waist-shaped groove 15 is provided on the extension arm 14. A fixing column 12 is arranged on the disk surface of the rotating disk 11. The fixing column 12 is built into and slides along the waist-shaped groove 15. When the rotating disk 11 rotates, the fixing column 12 can slide in the waist-shaped groove 15, so the half gear 13 will periodically flip back and forth.

[0027] The discharge bottom plate 6 is connected to the four supporting legs 5 and is suspended in the air. The discharge bottom plate 6 is provided with discharge ports 10 on both sides of the plate surface. The collection box 9 is connected vertically. The collection box 9 slides to align with the discharge port 10 on one side and pours out the ground material inside. The discharge bottom plate 6 is suspended in the air, and a corresponding collection hopper can be placed under the discharge port 10 to facilitate material recovery.

[0028] Vertical support plates 7 are respectively provided at the four corners of the top surface of the discharge bottom plate 6. The same sliding column 8 is slidably installed between the two support plates 7 aligned along the length direction. A collecting box 9 is connected between the sliding columns 8 on the front and rear sides. The collecting box 9 is placed on the discharge bottom plate 6 and slides on its plate surface. The upper surfaces of the two sliding columns 8 are provided with teeth that maintain meshing transmission with the corresponding half gears 13 above.

[0029] During the periodic flipping back and forth, the half gear 13 will also drive the two sliding columns 8 below to slide back and forth periodically. The collection box 9 is located below the temporary storage trough 4, and the box opening of the collection box 9 matches the shape of the slot opening of the temporary storage trough 4. During the back and forth sliding of the collection box 9, the collection box 9 will be periodically flush with the temporary storage trough 4 and used to receive materials. When the collection box 9 slides over the temporary storage trough 4, the solid plate set on the left or right side of the collection box 9 will block the temporary storage trough 4 to prevent material leakage. The purpose of this design is to prevent excessive accumulation of materials in the temporary storage trough 4 from leaking into the collection box 9 and leaking out from the discharge port 10, and the collection hopper below the discharge port 10 will not receive enough materials in a short period of time.

[0030] During the grinding stage, the double-opening baffle at the bottom of the grinding jar 1 is in a closed state, which can ensure that the material in the grinding jar 1 is fully ground. After the grinding is completed, the lower baffle is opened to release the ground material. Then the baffle is closed again and new material is poured in.

[0031] In the state of accepting materials, Figure 1 In the state shown, the extension arm 14 is in a vertical state, the collecting box 9 is aligned with the temporary storage trough 4, a part of the material is received in the collecting box 9 and then slid to the discharge port 10 on one side for unloading, and then the collecting box 9 slides in the opposite direction and aligns with the temporary storage trough 4 for a second time, and then slides to the discharge port 10 on the other side for unloading. During the entire grinding process, the grinding speed of the grinding roller 3 does not need to be too fast, that is, the rotation frequency of the rotating disc 11 and the frequency of the collection box 9 moving back and forth do not need to be too high, so as to provide a certain amount of time for the material to be received and released. Each time part of the material is released from the discharge port 10, the entire material recovery process can continue, and the discharge ports 10 on both sides discharge the material at intervals, which also provides convenience for subsequent staff to recover materials and replace the hoppers in time.

[0032] 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 within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
