Preferably, the spiral interval of the spiral chute is 600-1000mm.

Preferably, a plurality of buffer rubber balls are fixedly arranged on the inner wall of the ball inlet pipe, and the distance between each buffer rubber ball and the corresponding buffer rubber ball is slightly smaller than the diameter of the ball body.

Preferably, the upper surface of the bottom of the spiral chute is fixedly provided with a speed reducing belt assembly, and the number of the speed reducing belts in the speed reducing belt assembly is 2-4.

Preferably, a deceleration friction pad is fixedly arranged on the upper surface of the bottom of the spiral chute and is positioned on the front side of the deceleration strip assembly.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses with traditional tilting baffle change for the direction subassembly on the access door, can be when the spheroid is discharged, through the spiral chute, change spheroidal direction of motion and motion form, make the spheroid of straight line form of jettisoninging become the spheroid that moves down along the direction chute roll, turn into the energy of vertical direction into the kinetic energy of horizontal direction, the casing in the spiral chute outside can block the spheroid and splash simultaneously, prevents to hinder the people. When the spheroid moves near spiral chute export, receive the influence of deceleration strip subassembly and speed reduction friction pad, spheroid speed decline, finally with less initial velocity, roll landing to ball pond in, simultaneously the utility model discloses still be provided with the rubber cushion ball on the inner wall of goal pipe, the rubber cushion ball can cushion the spheroid of whereabouts, prevents that the spheroid from impacting the spiral chute when the whereabouts to reduce the stability of being connected between direction subassembly and the vertical mill.
