Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

example 1: referring to fig. 1 to 4, a rotary membrane rupture device includes: an operating lever 1; the cylinder 2 is rotatably connected to the lower part of the operating rod 1, and the lower end face of the cylinder 2 is fixedly connected with the blade 3; the motor 5 is fixedly connected to the operating rod 1, a rotating shaft of the motor 5 is connected with the cylinder 2, and the motor 5 drives the cylinder 2 to rotate around the operating rod 1; a power supply electrically connected to the motor 5; and the switch 7 is connected with the motor 5 and the power supply in series, and the switch 7 is fixedly connected to the upper part of the operating rod 1. The switch 7 can be a forward and reverse rotation switch with the brand of forward flight type KCD 1.

The utility model discloses a motor 5 drives barrel 2 and rotates, and barrel 2 rotates and makes blade 3 of barrel 2 lower part rotate around barrel 2 the central axis, and blade 3 cuts the plastic film and makes the plastic film cut a hole, the utility model discloses need not the manpower rotatory barrel 2 and punches, it is more laborsaving; through 3 cutting plastic films of blade for the plastic film part by the cutting is separated with other parts of plastic film completely, rather than being impressed in soil, can not cause the pore wall to lead to the seedling nutrient to be blockked by the plastic film by plastic film mulching around, the utility model discloses do benefit to the tobacco seedling growth more.

Further, the direction of the edge of the blade 3 is tangential to the side of the cylinder 2.

So that the resistance to cutting by the blade 3 is minimized.
