the feed hopper 61 is divided into three sections, and is divided into a material gathering section 611, a buffer section 612 and a uniform section 613 from top to bottom; the channel cross-sectional area of the polymer portion 611 is larger than the channel cross-sectional area of the equalizing portion 613;

the angle a formed between the bottom plane of the polymer portion 611 and the horizontal ground is smaller than the angle b formed between the bottom plane of the homogenizing portion 613 and the horizontal ground.

In the above implementation, specifically, when in use, the material 5 enters the hopper body 1 from the feeding hole 3 through the feeding device 6, and the feeding end at the upper end of the feeding device 6 is a belt conveying mechanism for conveying the material 5; the belt conveying mechanism continuously supplies materials to the feeding device 6, the feeding device 6 can prevent excessive materials from being accumulated at the feeding hole, the materials at the outlets of the buffer part 612 and the equalizing part 613 are continuously supplied, and accumulation pressure is not generated; the balance of the feeding amount and the lifting amount is realized, so that the safe and stable operation of the bucket elevator is also realized; more specifically, the feeding device 6 comprises a feeding hopper 61 which is obliquely arranged and has an open top, a vibrating device 62 which is fixedly arranged at the bottom end of a discharge port of the feeding hopper 61, and a bracket 63 which is used for supporting the feeding hopper 61; the feed hopper 61 is divided into three sections, and is divided into a material gathering section 611, a buffer section 612 and a uniform section 613 from top to bottom; the channel cross-sectional area of the polymer portion 611 is larger than the channel cross-sectional area of the equalizing portion 613; the angle a formed between the bottom plane of the polymer portion 611 and the horizontal ground is smaller than the angle b formed between the bottom plane of the homogenizing portion 613 and the horizontal ground. The material collecting portion 611, the buffer portion 612, and the equalizing portion 613 can discharge the material 5 in three stages, the buffer portion 612 has the largest opening cross section and the largest accommodation amount, and can buffer and receive the material 5 from the material collecting portion 611, while the material 5 from the material accumulating part 611 can be more largely buffered by the buffering part 612, the excessive material 5 is prevented from entering the equalizing part 613, since the angle a formed between the bottom plane of the mass 611 and the horizontal ground is smaller than the angle b formed between the bottom plane of the bisecting portion 613 and the horizontal ground, with the mass 5 on the bisecting portion 613, because the channel is narrowed and the inclination angle is increased, the materials 5 obtain larger kinetic energy on the equally dividing part 613 and are evenly fed into the feeding hole 3, so that excessive materials are prevented from being accumulated in the feeding hole 3, so that the material at the outlet of the buffer 612 and equalizing 613 is continuously fed and no pile-up is produced.
