Plant straw manufacturing apparatus wherein the belt material body is reciprocated in the axial direction by the pipe device to drive the pipe rod to clean the inside of the plant straw, thereby improving the production yield and efficiency of plant straws

The present invention relates to a plant straw manufacturing apparatus, which includes a belt material body, a pipe device and a moving device. The belt material body has a rotating shaft and one or more axial grooves. The pipe device has one or more pipe rods corresponding to the one or more axial grooves. The moving device can move in the axial direction and is set at the bottom of the pipe device. Furthermore, the one or more pipe rods pass through the moving device and reciprocate in the axial direction to be inserted into the one or more axial grooves. In this way, the action of cleaning the inside of the plant straw placed in the one or more axial grooves is performed to achieve the purpose of improving the production yield and efficiency of manufacturing plant straws. The belt material body further includes an outer periphery recessed to form the one or more axial grooves; a first material outer side surface located adjacent to one end of the outer periphery; a second material outer side surface arrang
