The invention relates to the field of material conveying and discloses a material conveying hopper and a material conveying system. The material conveying hopper (1) is provided with a conveying channel (4) with a feed port (2) and a discharge port (3), an arc surface (5) extending towards the discharge port (3) is formed at the position, close to the discharge port (3), of the conveying bottom surface of the conveying channel (4), the concave part of the arc surface (5) faces the conveying channel (4), the kinetic energy of material can be changed, the impact energy can be lowered, the falling speed of the material can be lowered, the speed at a material outlet and the speed of a conveying belt in the conveying direction are nearly uniform, and therefore abrasion between the material and the conveying belt caused by reacceleration of the material is reduced and the energy consumption of operation of the conveying belt is reduced.
