[0049] In this embodiment, the set of tooth rings 1 includes multiple tooth rings 1, and each tooth ring 1 is provided with a set of tooth tips 2. It should be noted that the number of tooth tips 2 in a set of tooth tips 2 corresponds to the number of first connecting parts on one tooth ring 1. As Figure 3 shown, if the number of the first connecting parts is four, then the number of tooth tips 2 in a set of tooth tips 2 is four. Specifically, the tooth ring 1 is a thin sheet structure, which can be circular or polygonal. Please refer to Figure 1 , in some embodiments, the tooth ring 1 further includes a first side edge 13, a second side edge 14, a third side edge, a fourth side edge, a first arc edge 15, a second arc edge 16, a third arc edge, and a fourth arc edge.

As Figure 1 shown, the first connecting surface 11 and the second connecting surface 12 are perpendicularly arranged to form an inward concave notch; correspondingly, the third connecting surface 21 and the fourth connecting surface 22 of the second connecting part are as Figure 2 shown. The third connecting surface 21 is in contact with the first connecting surface 11, and the fourth connecting surface 22 is in contact with the second connecting surface 12. Then the second connecting part forms a right-angled protrusion, and the second connecting part is embedded into the first connecting part and then locked by a fastener, which can significantly improve the connection strength between the tooth tip 2 and the gear ring 1. Further, the crushing tip 23 is wedge-shaped and is arranged at one end of the second connecting part extending outward. The crushing tip 23 protrudes out of the outer edge of the gear ring 1. During rotation, the crushing tip 23 can cut into the fruit shell of the tung oil fruit to improve the crushing effect of the tung oil fruit, and the connection method between the second connecting part and the first connecting part can make the crushing tip 23 more stable during rotation.

[0054] In this embodiment, a first connecting hole 17 is also provided in the middle of the gear ring 1. As Figure 3 shown, through the first connecting hole 17, the gear ring 1 can be sleeved outside the connecting roller shaft 3. There are a plurality of gear rings 1 on the connecting roller shaft 3, and one connecting roller shaft 3 is sleeved with one set of gear rings 1. And in this embodiment, the tooth tips 2 on the peripheries of two adjacent gear rings 1 are staggeredly distributed. As Figure 4As shown, this method can improve the crushing efficiency of tung fruits and make the crushing degree of tung fruits higher.

[0055] In this embodiment, according to the thickness of the outer shell of the tung fruit, the tooth tip 2 with a crushing tip 23 is provided and is embedded in the first connecting part, so that the crushing tip 23 protrudes out of the outer edge of the tooth ring 1. The tooth tips 2 of two adjacent tooth rings 1 on the same connecting roller shaft 3 are staggered in the axial direction of the connecting roller shaft 3, which fully improves the crushing efficiency of the outer shell of the tung fruit.

[0056] Please refer to Figure 3 , in some embodiments, a first keyway 18 and a second keyway 19 are further provided on the inner side wall of the first connecting hole 17, and the central axes of the first keyway 18 and the second keyway 19 are arranged at an angle; a plurality of third keyways and a plurality of fourth keyways are further provided on the connecting roller shaft 3. A third keyway matches with a first keyway 18, and a fourth keyway matches with a second keyway 19; the crushing teeth further include a plurality of key groups, and the number of key groups corresponds to the number of tooth rings 1 one by one. Each key group includes a first key and a second key. The first key is arranged in the first keyway 18, and the second key is arranged in the second keyway 19 for key connection of the tooth ring 1. By providing the first keyway 18 and the second keyway 19 on the inner side wall of the first connecting hole 17, and providing the third keyway and the fourth keyway on the connecting roller shaft 3, then placing the first key in the space formed by the first keyway 18 and the third keyway, and placing the second key in the space formed by the second keyway 19 and the fourth keyway, the stability and reliability between the tooth ring 1 and the connecting roller shaft 3 can be enhanced, and the situation of loosening or falling off can be prevented. Each tooth ring 1 matches with a key group on the connecting roller shaft 3, so as to provide more uniform connection force and better stability, reduce the vibration and shaking of the whole crushing teeth during the working process, and improve the crushing effect and working efficiency.

[0057] Please refer to Figure 4 , in some embodiments, it further includes 5 groups of partitions 5.

The thickness of the partition 5 is greater than the thickness of the tooth ring 1. The partition 5 is provided to control the distance between two adjacent tooth rings 1. The reason for this setting is that the crushing teeth are used in the crusher described later. The crusher requires at least two groups of crushing teeth and arranges the crushing teeth side by side. In this setting method, the tooth tip 2 in another group of crushing teeth will be embedded between two adjacent tooth rings 1 of the current group of crushing teeth during rotation. The partition 5 can ensure the firm connection between the tooth rings 1 in the same group. At the same time, when the tooth tip 2 in another group enters between two adjacent tooth rings 1 of the current group of crushing teeth, the partition 5 can block the remaining pores to avoid the carding of tung fruit debris between two adjacent tooth rings 1, thereby improving the crushing efficiency of tung fruit debris.

[0058] Please refer to Figure 4 , in some embodiments, it further includes 4 sets of bearings.
