[0039]

[0040] When the present application works, the belt 17 feeds the crushed corn straw into the baling chamber of the belt type round bale baler 6, the movable baling chamber belt 24 and the fixed baling chamber belt 21 are driven by steel rollers, and the surface of the belt has convex patterns to increase the friction with the bale. The corn straw entering the baling chamber rotates in the counterclockwise direction under the rubbing of the movable baling chamber belt 24 and the fixed baling chamber belt 21, and automatically forms a small round bale. As the corn straw is continuously fed, the diameter of the bale gradually increases, so that the fixed baling chamber belt tensioning roller 19 swings left and right under the pull of the fixed baling chamber belt 21, and the movable baling chamber belt tensioning roller 25 swings up and down under the pull of the movable baling chamber belt 24, thereby expanding the volume of the bale accommodating space between the fixed baling chamber belt 21 and the movable baling chamber belt 24.

The resistance indirectly added by the two spring tensioners to the fixed baling chamber belt 21 and the movable baling chamber belt 24 always ensures the compactness of the bale during the increase of the bale. When the diameter of the bale reaches the diameter of the baling chamber, as the corn straw continues to be fed, the bale is continuously compacted, which will cause the pressure in the piston rod cavity of the baling chamber opening cylinder to continuously increase. When the pressure in the piston rod cavity reaches the set value, that is, the density of the bale reaches the required value, the controller sends a signal, the belt 17 is disconnected and separated, the grass feeding is stopped, the automatic net (film) winding mechanism performs the net feeding and cutting operation, then the baling chamber opening cylinder 22 works, the movable baling chamber 23 opens, and the bale is discharged, then the baling chamber is closed, and the control system detects the closing signal, the belt clutch cylinder works, the clutch is combined, and the belt starts to feed the grass, completing a baling work cycle. At the same time, the grass fed by the throwing cylinder enters the grass storage box 14, and when the belt 17 starts to feed the grass, the agitator 15 rotates with the belt driving shaft to uniformly push the stored grass left and right to the belt 17, and the belt 17 feeds the grass into the belt type round bale baler 6, realizing continuous operation without stopping.
