The crushing of oil-tea camellia seed raw materials is usually carried out by using an oil-tea camellia seed crusher. For example, Chinese Utility Model Patent Nos. 201922379172.5 and 202220631704.9 both disclose an oil-tea camellia seed crusher. In the existing oil-tea camellia seed crusher, a tooth part for crushing oil-tea camellia seeds is arranged on the surface of a crushing roller. However, the tooth part is in the form of a long strip arranged continuously along the axial direction of the crushing roller, and the oil-tea camellia seeds passing through the crushing gap formed between the two crushing rollers arranged at intervals and rotating relative to each other are crushed by extrusion. The crushing by extrusion has the following disadvantages: when a large number of oil-tea camellia seed particles fall on the surface of the crushing roller, the oil-tea camellia seed particles are easily pushed and extruded against each other, causing phenomena such as material slipping and seed jumping during the falling into the crushing gap; in addition, many extruded oil-tea camellia seed particles are only pressed into flat pieces, and are not crushed, which results in poor crushing effect of the oil-tea camellia seed raw materials.

[0028] The application will be further described below in combination with the drawings. The application will be further described below in combination with the drawings.

[0029] Embodiment 1

[0030] Reference Figures 1 to 6 The oil-tea camellia seed crusher comprises a shell 1 in a vertically arranged shell structure, a top of the shell 1 is communicated with a feeding hopper 11, the feeding hopper 11 is a reverse conical shell with openings at the upper and lower ends, a main crushing unit 2 is arranged in the shell 1 and located directly below the feeding hopper 11, and the main crushing unit 2 is composed of two main crushing rollers 21 arranged in parallel and rotating oppositely. A plurality of annular blades 3 are arranged equidistantly on the surface of the main crushing roller 21, and the annular blades 3 are coaxially arranged with the main crushing roller 21. With reference to the specific embodiments, Figure 2 and Figure 3 The annular blades 3 of the present embodiment are gradually thinned from the middle to the edge, and the annular blades 3 on the two main crushing rollers 21 are arranged staggered to each other and staggered by 0.5 to 2 cm, which is slightly smaller than the particle size of the oil-tea camellia seeds.

[0031] In the above structure, the oil-tea camellia seed materials fall from the feeding hopper 11 to the main crushing unit 2, the two main crushing rollers 21 of the main crushing unit 2 rotate oppositely, and the annular blades 3 arranged radially on the two main crushing rollers 21 form an interlocking engagement similar to "scissors", replacing the extrusion effect of the existing long strip structure tooth part, to shear and crush the oil-tea camellia seed particles passing between the two main crushing rollers 21, significantly reducing the sliding and jumping of the oil-tea camellia seed particles, and effectively improving the crushing efficiency. At the same time, this interlocking engagement method is also not easy to cause the disadvantageous situation of material jamming the main crushing unit 2, and does not need to set the cleaning brush disclosed in the Chinese utility model patents with application number 201922379172.5 and application number 202220631704.9. Moreover, the annular blade 3 adopts a structure of thick in the middle and thin at the edge, which effectively ensures the strength of the annular blade 3 while ensuring the edge shearing capacity.

[0032] Further, in the present embodiment, with reference to the specific embodiments, Figure 4 the annular blade 3 has a plurality of tooth-shaped grooves 31 arranged in a circular array along the edge of the annular blade 3. In the above structure, the contact surface with the oil-tea camellia seed particles is further increased by the tooth-shaped grooves 31, and the shearing angle different from the edge of the annular blade 3 is generated by the groove wall surface of the tooth-shaped grooves 31, to improve the shearing and crushing efficiency of the annular blade 3.

[0033] Further, in the present embodiment, with reference to the specific embodiments, Figure 1 and Figure 4, the side of the two main crushing rollers 21 close to each other is upwardly rotating, the tooth-shaped groove 31 has a long wall surface and a short wall surface arranged along the edge of the annular blade 3, the ratio of the length a of the short wall surface to the length A of the long wall surface is 0.2-0.5:1, and the long wall surface is opposite to the rotating direction of the main crushing roller 21, and the short wall surface is opposite to the rotating direction of the main crushing roller 21. In the above structure, the side of the two main crushing rollers 21 close to each other is upwardly rotating, and good shearing crushing efficiency is generated by forming opposite shearing force with the falling materials. In addition, the long wall surface is opposite to the rotating direction of the main crushing roller 21, and the long wall surface is opposite to the falling materials, the contact area of the tooth-shaped groove 31 and the falling materials is ensured by the long wall surface, and more efficient shearing crushing efficiency is formed.

[0034] Further, in the embodiment, with reference to Figure 4 , the wedge angle b of the tooth tip 30 of the tooth-shaped groove 31 is 60-90°, and the tooth tip 30 is located near the middle of the radial direction of the annular blade 3. By limiting the size of the wedge angle b, the opening of the tooth-shaped groove 31 is ensured. In addition, by limiting the position of the tooth tip 30, the strength of the annular blade 3 is not adversely affected by the tooth-shaped groove 31, and the annular blade 3 has sufficient strength.

[0035] In the embodiment, with reference to Figure 5 , the driving structure of the main crushing unit 2 is that one end of the two main crushing rollers 21 respectively passes through the shell 1 and is provided with a main gear 6, the two main gears 6 are meshed with each other, and the end of one of the main crushing rollers 21 is connected with a main drive motor 61, the main drive motor 61 drives one of the main crushing rollers 21 to rotate, and the other main crushing roller 21 is driven to rotate by the two main gears 6 meshed with each other.

[0036] Embodiment 2

[0037] With reference to Figures 7 to 10 , the difference between the oil tea seed crusher of the embodiment and the oil tea seed crusher of the embodiment 1 is that the pre-crushing unit 4 is further arranged between the feeding hopper 11 and the main crushing unit 2 in the shell 1 of the oil tea seed crusher of the embodiment. The pre-crushing unit 4 is composed of two wave-shaped rollers 41 arranged in parallel and rotating relative to each other, and the cross section of the wave-shaped roller 41 is composed of a wave-shaped surface composed of an arc convex surface 42 and an arc concave surface 43 alternately. When arranged, with reference to Figure 8, the arc convex surface 42 of one wave-shaped roller 41 is arranged opposite to the arc concave surface 43 of the other wave-shaped roller 41 to form the working gap 40. In this structure, the working gap 40 is formed in the form of a "jaw" by the opposite convex surface and concave surface, so that the material can stay in the working gap 40 for a long time, thereby forming a better extrusion pre-crushing effect. After the "extrusion" pre-crushing of the pre-crushing unit 4, the material particles are already broken, and then enter the "shearing" crushing of the main crushing unit 2, thereby realizing a better crushing effect. The oil tea seed particle size is generally 1.5 to 2.5 cm, so the width of the working gap 40 is set to 0.5 to 2 cm, which is slightly smaller than the particle size of the oil tea seed.

[0038] It should be particularly pointed out that in the embodiment, when running, the side close to each other of the two wave-shaped rollers 41 rotates downward, which can effectively avoid the material falling on the wave-shaped roller 41 from being thrown away due to rotation.

[0039] Further, in the embodiment, a guide hopper 9 is further arranged between the pre-crushing unit 4 and the main crushing unit 2 in the machine shell 1. The guide hopper 9 is a reverse conical shell with openings at the upper and lower ends. The upper end of the guide hopper 9 abuts against the inner wall of the machine shell 1, and the lower end is located directly above the main crushing unit 2. Since the particle material falling on the pre-crushing unit 4 inevitably has the phenomenon of jumping seeds, the particle material bounced off the pre-crushing unit 4 is collected by the guide hopper 9 and then guided into the main crushing unit 2 for direct crushing, so as to ensure that the bounced-off material can also be crushed, thereby ensuring the crushing rate of the material.

[0040] Further, in the embodiment, the feed hopper 11 of the machine shell 1 extends to both ends of the wave-shaped roller 41 along the axial direction of the wave-shaped roller 41, the opening at the upper end of the guide hopper 9 extends to both ends of the wave-shaped roller 41 along the axial direction of the wave-shaped roller 41, and the opening at the lower end of the guide hopper 9 extends to both ends of the main crushing roller 21 along the axial direction of the main crushing roller 21. In the above structure, the structure of the feed hopper 11 and the guide hopper 9 realizes uniform feeding along the axial direction of the wave-shaped roller 41 and the axial direction of the main crushing roller 21.

[0041] In the embodiment, with reference to Figure 9 , the driving structure of the pre-crushing unit 4 is that one end of each wave-shaped roller 41 penetrates through the machine shell 1 and is provided with a pinion 5, the two pinions 5 are meshed with each other, and the end of one wave-shaped roller 41 is connected with a sub-driving motor 51. The sub-driving motor 51 drives one wave-shaped roller 41 to rotate, and the other wave-shaped roller 41 is driven to rotate by the two meshed pinions 5.
