This is existing technology and will not be described in detail here. When the user needs to use the conveyor body 1 and feed coal or plant straw to the heating boiler, the first hydraulic cylinder 7 is activated to retract and pull the linkage arm 6 to rotate. The rotating linkage arm 6 drives the rotating guide plate 5 to rotate, causing the rotating guide plate 5 to rotate to the left and abut against the inner side wall of the feeding hopper 2.

[0028] Therefore, the coal is added into the inside of the feeding hopper 2, and the coal falls along the rotating guide plate 5 to the right space in the inside of the feeding hopper 2. At the same time, the driving motor 11 is started to drive the second gear 14 to rotate, the rotating second gear 14 drives the two first gears 9 on the right to rotate, and the rotating first gears 9 drive the two crushing rollers 4 to crush the coal, and the crushed coal is discharged through the bottom of the feeding hopper 2 for feeding.

[0029] Similarly, when the plant straw needs to be fed, the second hydraulic cylinder 12 is started to contract to pull the fixed plate 13 to drive the driving motor 11 to move left, so that the second gear 14 is engaged with the first gear 9 on the left, so that the driving motor 11 is started to drive the two first gears 9 on the left to rotate and drive the blade cutting roller 3 to rotate, and the first hydraulic cylinder 7 is started to extend, so that the rotating guide plate 5 rotates right to guide the plant straw to the left space, and then the plant straw is cut by the high-speed rotating blade cutting roller 3, and the cut and crushed plant straw falls through the bottom discharge port and is discharged for feeding.

[0030] Therefore, the effect of feeding the heating boiler is achieved, the plant straw and the coal are crushed and integrated in the inside of the feeding hopper 2, so that the plant straw does not need to be crushed and fed again, and the coal clumping is also avoided to cause insufficient combustion, the two functions are integrated and switchable, so that the coal does not need to be crushed by another device, the feeding operation complexity is reduced, the practicability of the feeding device is improved, and the use is facilitated.

[0031] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
