[0011] Beneficial effects

[0012] The utility model provides a drying device for straw raw materials, which has the following beneficial effects:

[0013] 1. For the drying device for straw raw materials, during the use of the utility model, the positioning cross bar can be connected to the transmission chain. Then, the plurality of connecting clamping plates are passed through the interiors of the plurality of connecting through grooves. Next, the connecting sliding plate is moved towards the direction close to the connecting through groove. The connecting plate will drive the positioning clamping rod to move, and the elastic element will be compressed. Then, the positioning cross bar is pressed downwards. The plurality of connecting clamping plates will move downwards until they cannot move. At this time, the connecting sliding plate is released, and the elastic element starts to elongate. The connecting sliding plate will drive the connecting plate to return to the original state in the direction away from the connecting through groove. The plurality of positioning clamping rods will move towards the direction close to the connecting clamping plates. Finally, the horizontal ends of the plurality of positioning clamping rods will be clamped into the interiors of the corresponding positioning clamping grooves, realizing the positioning and fixing of the positioning cross bar. The operation is simple and convenient, and the installation speed is improved.

[0014] 2. The drying device for straw raw materials. During the use of this utility model, when the connecting card plate passes through the inside of the connecting through groove and moves downward, the outer wall of the connecting card plate contacts the inclined surface of the positioning rod. The positioning rod will be forced to move away from the connecting card plate, and the elastic element will be compressed until the positioning card slot moves to the position of the horizontal end of the positioning rod. Then the elastic element begins to elongate, and the horizontal end of the positioning rod moves towards the connecting card plate. Finally, the horizontal end of the positioning rod moves into the positioning card slot, eliminating the need for manual operation to move the connecting slide plate, facilitating the use of the device. In addition, during the movement of the installation connecting plate, it will move along the outer wall of the connecting slide rod, improving the stability during the operation of the connecting slide plate.
