Description

Technical Field

[0001] The utility model relates to the field of crop production tools, in particular to a handheld plastic film perforating device. Background Art

[0002] A handheld plastic film perforating device is an agricultural tool mainly used for punching holes in the already laid plastic film so that crops can be sown or transplanted through the plastic film during planting. This device is usually small in size, easy to carry and operate, and is suitable for large areas of plastic film covering in greenhouses, greenhouses or outdoors.

[0003] A handheld plastic film perforating device generally consists of the following parts: a handle: facilitating the operator to hold and operate. A perforating component: usually a sharp metal component for punching holes in the plastic film. Using a handheld plastic film perforating device can save labor, improve the perforating efficiency, reduce damage to the plastic film, and ensure the uniformity of crop growth and the integrity of the plastic film.

[0004] However, during the use of this traditional handheld plastic film perforating device, the operator needs to continuously apply downward force to drive the device. During a long working process, it not only consumes a large amount of physical strength of the operator but also reduces the efficiency. Therefore, in the existing handheld plastic film perforating device, a gas port is installed at the position of the perforating component, and a small gas cylinder is externally installed to convey gas into the gas port and make the gas port generate a flame to heat the perforating component. In this way, it is easy to achieve the perforation of the plastic film by the perforating component. However, this method has certain dangers. Since continuous heating by fire is required near the perforating component, during the perforation process, once the broken plastic film comes into contact with the flame of the gas port, it is extremely easy to cause the plastic film to catch fire.
