Description

Tobacco field mulching film punching device Technical Field The utility model relates to the technical field of mulching film punching, in particular to a tobacco field mulching film punching device. Background In the flue-cured tobacco planting process, the soil is leveled firstly, then ridges are formed, holes are dug on the ridges at certain intervals, then tobacco seeds are covered in the holes, finally, the film is covered, the tobacco seeds are pulled out from the openings at the tobacco seeds, the root of the tobacco seeds is covered with the soil while the film is pressed, the root of the tobacco seeds is covered, the film is prevented from being contacted with the tobacco seeds, when the tobacco seeds are planted at the openings on the film to pull out the tobacco seeds, the film is broken by fingers to pull out the tobacco seeds, the tobacco seeds below the film are easily broken when the film is opened, the opening on the film is easily oversized or undersized, the opening of the film is disordered, and the requirements are not met. The utility model patent with the patent number of CN217446039U discloses an agricultural planting film perforating device, which comprises a cylinder, an intermediate body and a vertical rod; the bottom of the cylinder body is provided with a cutting edge, two sides of the top of the cylinder body are symmetrically provided with connecting sleeves, and springs are arranged in the connecting sleeves; the lower part of the intermediate body is symmetrically provided with a sliding rod corresponding to the connecting sleeve, the sliding rod is in sliding connection with the connecting sleeve and is in contact with the spring surface, the middle part of the intermediate body is provided with a detachable ejector rod, and the lower end of the ejector rod is conical; when in use, combining with the figures 1 to 5, holding the handle above the upright 3 with both hands, then moving the cylinder 1 to the position where the mulch film needs to be cut, pressing downwards with force, cutting the mulch film by using the blade 101 at the bottom of the cylinder 1, continuing to apply force, generating resistance force between the cylinder 1 and the ground, which is larger than the elasticity of the spring 103, compressing the spring 103 by the slide bar 201, driving the ejector rod 4 downwards, puncturing the cut film by using the conical structure at the bottom end of the ejector rod 4, preventing the film from falling off by the conical structure, loosening hands, pushing the slide bar 201 by the spring 103 to reset, completing one-time operation, cutting the mulch film and collecting the cut film, in the patent, cutting the mulch film by the blade by applying force, collecting the cut film by the ejector rod, but in the use process, because the film itself has toughness and can deform, the blade is not in the process of cutting the film, the film is hard to deform because the blade is flat in the process of cutting the film, the film is difficult to form a whole film body and the cut film is completely connected with the film, secondary cutting is required and takes a long time.
