The specific structure of the rolling shutter frame 123 is as follows: the rolling frame 123 is disposed on the frame 121, and the rolling frame 123 is provided with an output shaft for connecting with the rolling rod 11.

The rolling shutter car 120 has a working state that the frame 121 advances and the rolling shutter frame 123 ascends or descends, the ascending and descending speed of the rolling shutter frame 123 is gradually reduced from bottom to top, and the rotating speed of the output end is gradually reduced from bottom to top.

In the present embodiment, the following manner is adopted to implement the above functions: one of the traveling members 122 includes a first bevel gear 134, and the first bevel gear 134 is fixed coaxially with the rotation shaft of the traveling member 122.

The greenhouse rolling device 10 in the prior art is difficult to install the traction member 160 because the traveling speed of the traction member 160 must be twice of the speed of the traveling wheel, and the speed of the rolling rod 11 is not matched with the speed of the traveling wheel, so that the motor 131 needs to be additionally arranged to realize the purpose, and the cost is too high.

In this embodiment, since the traveling speed of the traction member 160 is matched with the rotation speed of the winding rod 11 through the structural improvement, that is, the speed of the traction member 160 is constant, the speed of the winding rod 11 is gradually decreased or increased, and the traveling wheels are rotated passively, so that the traveling speed of the movable pulley 164 is always consistent with the traveling speed of the greenhouse roller shutter robot 12.

The take-up pulley 165 is coaxially fixed with the rotating shaft of the first traveling wheel 130, and the traction rope 161 is wound around the take-up pulley 165.

The movable pulley 164 is detachably connected with the frame 121.

The number of the driving assemblies 141 may be two, and the two driving assemblies 141 have a better supporting function because the greenhouse rolling shutter is heavy.
