Title: Quickly-repairable pellet grill

Description:
TECHNICAL FIELD 
     The present disclosure relates to pellet grills, and in particular, relates to a quickly-repairable pellet grill. 
     BACKGROUND 
     Pellet grills are heated by combustion of pellets. A conventional pellet grill typically includes a grill body. A combustion chamber is disposed in the grill body. A grilling grid is disposed over the combustion chamber. A feed channel is disposed at a side portion of the grill body, wherein the pellets are transported to the combustion chamber via a screw conveyor mounted at the feed channel. The pellets are combusted in the combustion chamber to generate heat, such that food on the grilling grid is well baked. However, at present, a screw conveying mechanism is fixed to the feed channel by welding or the like. As a result, the screw conveying mechanism fails to be detached for repair, and thus use of the grill is inconvenient.

In this way, a maintenance worker checks and repair the detached fuel conveying and stirring mechanism, and the stirrer may be quickly replaced, such that use of the grill is more convenient. In addition, configuration of the handle facilitates detaching of the fuel conveying and stirring mechanism. Further, when the pellet grill operates normally, configuration of the fixing frame achieves a protection and limiting effect on the motor, reduces an angle of rotation in the case of dead-lock of the motor in fuel feeding to reduce a force suffered by the screw of the rotation shaft of the motor, thereby achieving a protection effect. This structure has the advantages of use convenience and improving use experience of such products.
