Puncher for agriculture field mulching film

Abstract

The invention discloses a puncher for agriculture field mulching film. The puncher comprises a punching cylinder, wherein a lower edge of the punching cylinder is a cutting blade, a recycling cylinderis sleeved in the punching cylinder, a recycling shaft is arranged in the recycling cylinder, an upper side of the punching cylinder is fixedly connected with a mounting seat through a first connecting rod, handles are fixedly connected to a left side and a right side of the mounting seat, a motor is fixedly mounted on the mounting seat, and the recycling cylinder and the recycling shaft are driven to rotate by the motor. In a process of punching the agriculture field mulching film, the cutting blade cuts the mulching film, a limiting plate is used for pressing the mulching film downwards anda spiral sheet is used for conveying soil to cover a punched part of the mulching film, the mulching film is prevented from being damaged, meanwhile, a burr and the limiting sheet are used for recycling the mulching film to the recycling shaft, and the recycled mulching film can be prevented from polluting the environment.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to an agricultural field film puncher. Background technique [0002] It is very common to plant crops under plastic film covering. After covering the plastic film, it can reduce the impact of raindrops, prevent the erosion of the soil surface, and prevent the formation of soil surface crusts. It can effectively reduce the evaporation of soil moisture, protect moisture during drought, and increase moisture after rain. Water absorption and growth can improve the efficiency of soil water use; however, after covering the plastic film, it will also have some adverse effects, such as: hindering the direct infiltration of rainfall, and the air tightness of the film also hinders the interface between the farmland soil and the atmosphere. Gas exchange, according to measurements, after mulching, the CO2 concentration in the rhizosphere of crops can reach 2.6%-5.5%, which is 3-5...

AI Technical Summary

Problems solved by technology

[0003] In order to reduce the adverse effects of plastic film on crops, agricultural personnel need to punch holes in the plastic film in the field. Manual drilling is not only time-consuming and laborious, but also during the punching process, the plastic film at the punched part falls off and remains in the soil. On the one hand, due to Plastics that are difficult to degrade will cause long-term white pollution of the soil environment and affect the growth of crops. On the other hand, microplastics can be absorbed by plants and further enter the human body, causing long-term harm and hidden dangers to human health.
