An adjustable mulch punching machine

Abstract

The invention relates to an adjustable mulching film perforating machine. The machine comprises a perforating wheel and a supporting frame which are connected in a shaft driving mode. The perforating wheel comprises perforating tool bits, fixing pieces, a web, screws and a wheel rim, the perforating tool bits are fixedly connected with the fixing pieces and meanwhile connected with the wheel rim in a sleeved mode, and the wheel rim is composed of at least two wheel pieces. A fixing ring is arranged on the web and connected with the screws through nuts, and the other end of each screw is fixedly connected with the corresponding fixing piece. The wheel rim formed by connecting the wheel pieces end to end in a staggered mode and the screws are used, the radius of the perforating wheel is adjusted by changing the attachment length between the adjacent wheel pieces and the length of the screws, the perimeter of the perforating wheel is changed, the aim of adjusting the arc distance between the perforating tool bits is achieved, and planting requirements of different crops are met. Besides, the machine is simple in structure, convenient to adjust and high in practical value.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an adjustable mulching film punching machine. Background technique [0002] As an agricultural planting and cultivation technology, plastic film mulching has the functions of increasing temperature, retaining water, retaining fertilizer, improving soil physical and chemical properties, improving soil fertility, inhibiting the growth of weeds, reducing diseases, and reducing humidity in the case of continuous rainfall. function, thereby promoting plant growth and development, early flowering and fruiting, and increasing yield. [0003] When using mulch mulching technology for crop planting, it is necessary to punch holes first, while traditional agriculture is achieved by manual punching, that is, after the mulch film is flattened, flat-headed wooden sticks or metal sharp objects are used on the border. The hole spacing requires that a certain depth of seeding holes be drill...

AI Technical Summary

Problems solved by technology

[0003] When using plastic film mulching technology to plant crops, holes must be drilled first, while traditional agriculture is realized by manual punching, that is, after the plastic film is flattened Use flat-headed wooden sticks or metal sharp objects to vertically pierce seeding holes of a certain depth on the furrow surface according to the requirements of row and hole spacing, and take out the film in the holes. This method is labor-intensive and low in efficiency.

With the continuous development of agricultural mechanization, the emergence of mulch punching machines has greatly reduced the labor intensity of farmers. However, the positions of the punchers of the commercially available mulch punching machines are fixed, and the hole spacing cannot be adjusted. Hole punching for crops with different hole spacing requirements
