The working ring 1 is continuously worn along with continuous processing in the axial direction, after the working ring is worn to a certain degree, namely, exceeds the discharge opening 2, the standby discharge opening 5 of the second layer becomes a new discharge opening 2, and the new discharge opening 2 has the same structure as the initial discharge opening 2. By analogy, the spare discharge opening 5 on the upper layer is continuously formed into a new discharge opening 2 until the working ring 1 is worn to be incapable of working. Evenly be equipped with a plurality of row's silo 6 along circumference on the working ring 1 lateral wall, the lower extreme of arranging silo 6 extends to the bottom of working ring 1, its upper end extends upwards to one side, row's silo 6 is the heliciform, and the helical direction with the direction of working ring 1 pivoted is unanimous.

The top of the discharge opening 2 is of a round angle structure, and the bottom and the top of the standby discharge opening 5 are of a round angle structure. The fillet structure can prevent stress concentration and is beneficial to the flow of material scraps. In this embodiment, when the working ring 1 rotates, two side surfaces of the discharge port 2 push the material chips upwards (axially upwards) and outwards (outside the working ring 1) along with the rotation of the working ring 1, the two side surfaces are arranged in parallel, and the other side surface does not block one side surface from pushing the material chips, that is, an axial mechanical thrust for discharging the material chips is formed. The material scraps are smoothly discharged along the axial direction of the working ring 1 (as shown by the dotted arrows in fig. 13) under the pushing action of the two sides of the discharge opening 2 along with the rotation of the working ring 1.
Example four
In this embodiment, the position of the discharge opening 2 is mainly changed, the structure of the discharge opening 2 is the same as that of the first embodiment, the second embodiment or the third embodiment, and the rest is the same as that of the first embodiment.
As shown in fig. 14 and 15, a spare discharge opening 5 is formed in the side wall of the working ring 1, and the spare discharge opening 5 is located above the discharge opening 2 and is used for discharging the scraps after the axial wear of the working ring 1 exceeds the discharge opening 2. Spare bin outlet 5 bottom and top are the fillet structure, and the fillet structure prevents stress concentration to be favorable to the mobile discharge of material bits. A plurality of material discharge grooves 6 are uniformly and annularly distributed on the outer side wall of the working ring 1, the material discharge grooves 6 are spiral, and the spiral direction is consistent with the rotating direction of the working ring 1. The discharge chute 6 is designed to facilitate the discharge of the chips upwards along the discharge chute 6. The discharge opening 2 and the standby discharge opening 5 are positioned in the discharge groove 6. In this embodiment, the chips discharged from the discharge opening 2 are discharged upwards through the discharge chute 6 for the first time, so that the chip discharge speed can be increased.

Through the design of coincidence of first side 9 with the third side 11 of discharge gate 6 with discharge gate 2, under the rotation of working ring 1, the discharge gate 2 exhaust material bits move towards fourth side 12 of discharge gate 6 backward promptly, and the second side 10 of discharge gate 2 sets up the biggest discharge space who forms the material bits with fourth side 12 interval for the material bits more fast more enter into in the discharge gate 6, improve row material efficiency. The first side surface 9 of the standby discharge opening 5 and the third side surface 11 of the discharge groove 6 are designed in an overlapped mode, the second side surface 10 and the fourth side surface 12 of the standby discharge opening 5 are arranged at intervals to form the maximum discharge space of cooling water, and the cooling water flowing out through the standby discharge opening 5 (when the standby discharge opening 5 is not changed into the discharge opening 2 due to abrasion of the working ring 1, the cooling water flows out from the standby discharge opening 5 to the outer side of the working ring 1 to assist in discharging), so that the material scraps in the discharge groove 6 are discharged, the optimal boosting effect is achieved, and the material discharge efficiency can be improved. If the discharge opening 2/standby discharge opening 5 is not overlapped with one side of the discharge chute 6, if the discharge opening 2/standby discharge opening 5 is arranged in the middle of the discharge chute 6 (the first side surface 9 and the second side surface 10 are not overlapped with the third side surface 11 and the fourth side surface 12), or if the second side surface 10 is overlapped with the fourth side surface 12, the discharge space between the second side surface 10 of the discharge opening 2/standby discharge opening 5 and the fourth side surface 12 of the discharge chute 6 is small, and the scraps cannot be discharged quickly.
