Detailed Description

Referring to fig. 1-6, the present invention provides a technical solution:

the utility model provides a feed bin feeder before thermal power factory stove, includes oven 1, and feeding chamber 9 has been seted up to the terminal surface before 1 oven, is equipped with front bezel 2 in the feeding chamber 9, and feeding chamber 9 front bezel left side is rotated install with 2 sliding connection's of front

bezel curb plate

3, and 2 rear end face downside rotations of front bezel are installed bottom plate 5, and feeding chamber 9 right-hand member face is equipped with threaded

rod

19, and 2 right sides of front bezel are rotated and are installed the screw block 12 with 19 threaded connection of threaded rod.

Specifically, an inner rotating shaft 16 is fixed in the middle of the right end face of the side plate 3, outer rotating shafts 11 rotatably connected with the inner rotating shaft 16 are fixed on the upper and lower sides of the front end face of the feeding cavity 9, a prismatic limiting cavity 17 is formed in the upper end face of the inner rotating shaft 16 and the middle of the upper outer rotating shaft 11, and a prismatic limiting rod 18 is inserted in the prismatic limiting cavity 17; the side panels 3 may be secured as they are expanded and contracted.

Furthermore, a limiting slide block 7 is fixed on the left end face of the front plate 2, and a limiting slide groove 4 connected with the limiting slide block 7 in a sliding manner is formed in the front end face of the side plate 3 and the left end face of the feeding cavity 9; the direction of movement of the front plate 2 can be limited.

Furthermore, the width of the bottom plate 5 is matched with that of the feeding cavity 9, and clamping plates 6 attached to the rear end of the feeding cavity 9 are fixed on the left side and the right side of the rear end of the bottom plate 5; the motion interval of the bottom plate 5 is limited, and the bottom plate 5 is prevented from falling off.

Furthermore, a groove 10 is formed in the right side of the front end face of the feeding cavity 9, a threaded rod 19 is fixed in the groove 10, a connecting block 13 matched with the groove 10 is fixed at the right end of the front plate 2, a thread block 12 is rotatably installed in the inner cavity of the connecting block 13, an annular limiting groove 15 is formed in the periphery of the thread block 12, and an annular limiting block 14 rotatably connected with the annular limiting groove 15 is fixed in the periphery of the inner cavity of the connecting block 13; the moving direction of the screw block 12 is limited.
