In the grass and rice straw forming machine, which is equipped with a transfer device that intensively supplies grass and rice straw to the forming section, a briquette forming chamber surrounded by a plurality of forming rollers is formed in the forming section, and a briquette forming chamber is formed in the forming section. The briquette winding core is provided with a briquette winding core along its axis position, and the briquette winding core is provided with a winding guide portion having the same length as the width of the supply port relative to the supply port of the briquette forming chamber. It is characterized by being integrally formed.

Function The above technical means of the present invention works as follows.

That is, the grass and rice straw raked and collected in the pick-up section are intensively supplied to the briquette forming chamber of the forming section by the transfer device. Then, in the briquette forming chamber, grass and rice straw are rotated by the rotation of multiple forming rollers, and guided to the winding core at the axial center by a winding guide part with the same length as the width of the supply port. The briquettes are then rolled up and formed into cylindrical briquettes. The formed briquettes are guided to a winding core and are sent out in an orderly manner while maintaining their cylindrical shape. The briquettes sent out from the briquette forming chamber are cut into predetermined lengths and then released.
