The barrel wall grinding brush head assemblies and the barrel bottom grinding brush head assemblies are arranged in a cross shape. Moreover, the brush heads on the barrel wall grinding brush head assemblies and the barrel bottom grinding brush head assemblies are fixedly mounted on corresponding brush head mounting plates. During the conversion of the forward and reverse rotation of the motor, the brush seedlings are prone to breakage, affecting the service life of the brush heads. Also, the brush seedlings are not easy to fix and the fixation is unreliable. At the same time, the contact between the brush seedlings and the inner wall of the barrel body is uneven, and the steel barrel is prone to random swinging during the grinding process, affecting the grinding quality.

[0004] In addition, since there is a certain distance between the end of the brush seedlings of the barrel wall grinding brush head assembly and the end of the brush seedlings of the barrel bottom grinding brush head assembly, the barrel wall between the two types of brush seedlings cannot be ground, affecting the grinding effect.
