Claims

[Scope of Claim for Utility Model Registration] (1) A rotor that rotates around a horizontal axis is provided in a rotary case, and a plurality of blades are provided approximately radially on the outer circumferential surface of the rotor, and a granule inlet is provided at the top of the case. The lower edge of the opposing wall surface facing the blade rotation direction of the inlet is formed into a roughly V-shape that is symmetrical with respect to the center line of the rotor axial width when viewed from above, and inside the inlet, A shielding portion having a constant short width in the rotor width direction is formed along the rotor rotational direction from the rear end in the rotor rotational direction of the input port to the front end edge in the rotor rotational direction of the opposing wall surface, and is located on the forward extension line of the shielding portion. is formed with an auxiliary input groove that opens downward and extends further forward than the front edge of the lower edge of the opposing wall surface, and inputs through the auxiliary input groove via a communication groove that opens downward along the slope of the opposite wall surface. A rotary valve with a bite prevention structure that is characterized by communicating with the front end of the mouth. (2) A structure for preventing jamming of a rotary valve according to claim 1 of the utility model registration, in which a wide portion is formed at the rear end of the shielding portion.
