[0030] The feeder structure also includes a feeding assembly 2, a discharging assembly 3, and a driving assembly 4. The driving assembly 4 is used to drive the rotating shaft 6 to rotate, thereby driving the blade assembly 7 to rotate.

[0031] The feeding assembly 2 comprises a feeding pipe 22 arranged at the top of the cylinder 11, and a feeding hopper 21 is arranged at the top of the feeding pipe 22, which is used to guide the material into the inside of the cylinder 11 through the feeding hopper 21 and the feeding pipe 22, and the bottom end of the feeding hopper 21 corresponds to the blade assembly 7, and the inner diameter of the bottom end of the feeding hopper 21 is smaller than the length of the arc-shaped blade 71.

[0032] The discharging assembly 3 comprises a discharging pipe 31 fixedly connected to the bottom of the cylinder 11, which is communicated with the cylinder 11 and located directly below the feeding pipe 22.

[0033] The first guide hole 111 and the second guide hole 112 are arranged on the cylinder 11, the feeding pipe 22 corresponds to and is communicated with the first guide hole 111, and the inner diameter of the feeding pipe 22 is equal to the diameter of the first guide hole 111; the discharging pipe 31 corresponds to and is communicated with the second guide hole 112, the inner diameter of the discharging pipe 31 is equal to the diameter of the second guide hole 112, and the edge of the second guide hole 112 is provided with a circular arc transition 113.

[0034] The blade assembly 7 comprises the arc-shaped blade 71 fixedly arranged on the outer wall of the rotating shaft 6, and the arc-shaped elastic member 72 is arranged at the end of the arc-shaped blade 71 away from the rotating shaft 6 and aligned with the arc-shaped blade 71; the middle part of the arc-shaped blade 71 and the middle part of the arc-shaped elastic member 72 are protruded, and the arc-shaped blade 71 and the arc-shaped elastic member 72 form an arch-shaped structure through the middle part protrusion, and the direction of the middle part protrusion of the arc-shaped blade 71 is opposite to that of the arc-shaped elastic member 72.

[0040] Since the middle parts of the arc-shaped blades 71 and the arc-shaped elastic members 72 protrude, when the blade assembly 7 rotates to guide the material, the material can be introduced between the adjacent two blade assemblies 7, and during the rotation of the adjacent two blade assemblies 7, the arc-shaped blades 71 and the arc-shaped elastic members 72 can guide a part of the material to be discharged from the two ends in the length direction, so that too much material is prevented from being accumulated between the adjacent two blade assemblies 7; meanwhile, the arc-shaped elastic members 72 are elastic, which helps to reduce or avoid the material being stuck between the arc-shaped elastic members 72 and the inner wall of the cylinder 11 during the rotation of the blade assembly 7, and the driving assembly 4 applies the torque to the two ends of the driving shaft 42 at the same time, which further helps to reduce or avoid the blade assembly 7 from being stuck.
