[0042] Referring to Figs. 1-2 The material discharging mechanism with the flow guiding function in the present application comprises a material collecting box 1, an inspection short section 2 and a material discharging hopper 3 arranged in sequence, the inspection short section 2 is detachably connected between the two, the internal space of the material discharging mechanism can be dredged by disassembling and assembling the inspection short section 2, and at the same time, it is beneficial to maintain and replace the anti-throwing structure and the wear-resistant structure.

[0043] The aggregate box 1 comprises a funnel structure to receive the falling material from the incoming equipment 4, the discharge hopper 3 comprises a receiving platform 31 and a discharge chute 32, the discharge chute 32 is obliquely inclined relative to the aggregate box 1, and a double-winged widened discharge port 33 is arranged at the bottom end of the oblique inclination.

[0044] The receiving platform 31 included in the discharge hopper 3 can receive the material after passing through the maintenance short section 2 and form a certain buffer, thereby avoiding the impact of direct material falling on the incoming equipment.

[0045] Combined with the obliquely inclined discharge chute 32 relative to the aggregate box 1, and the structure of arranging the obliquely inclined bottom end of the discharge chute 32 as a double-winged widened discharge port 33, a bevel flared horn structure can be formed, so that the material falling point is more uniformly distributed above the screening surface or the conveying belt of the incoming equipment, effectively avoiding local material stacking and blocking.

[0046] Through the cooperation of the receiving platform 31 and the discharge chute 32 included in the discharge hopper 3, combined with the obliquely inclined arrangement of the discharge chute 32, the position of the discharge port 33 can form a slope with a certain angle, which can alleviate the impact of the material on the screening surface or the belt surface of the incoming equipment.

[0047] In one specific embodiment, the aggregate box 1 comprises a vertical section 11 and a tapered section 12, which constitute the peripheral shape of the funnel, and the vertical section 11 and the tapered section 12 form the flat structure of the aggregate box 1 as a whole, which is beneficial to the full collection of the incoming material.

[0048] The length direction of the vertical section 11 is opposite to the width direction of the incoming equipment 4, which can well collect the material of the wide incoming surface of the material conveying equipment.

[0049] The tapered section 12 comprises oppositely arranged inclined plates 121, and the inner side wall of the inclined plate 121 is provided with a material collecting anti-punching steel 122, which can protect the easily damaged inclined surface part and give it anti-punching performance.
