Replaceable soil puncher

Abstract

The invention provides a replaceable soil puncher which includes a first main body and a second main body which have same structures, wherein each main body includes a gripping part, a tong arm which is in vertical connection with the gripping part, and an arc-shaped sharpening part which is connected to the lower end of the tong arm. The two main bodies pass through the lower ends of the tong arms via rivets and are pivotally connected. Each tong arm at a distal end extends downwardly and vertically into a connecting part which is threadedly wound together with a corresponding vertically extending fixed part of the arc-shaped sharpening part so as to constitute an integrated puncher. According to the replaceable soil puncher of the invention, the tong arm and the arc-shaped sharpening part are of a separable type so that when the arc-shaped sharpening part is damaged, only the arc-shaped sharpening part needs replacing and resources can be saved.

Description

【Technical field】 [0001] The invention relates to a special hole puncher for agricultural soil, especially a replaceable soil hole puncher. 【Background technique】 [0002] Mulch film is the ground covering film, usually transparent or black PE film, and also green and silver film, which is used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, and prevent pests from invading crops and certain microorganisms. function of diseased plant growth. [0003] In the prior art, the conventional mulch punching device is used, and the sharp puncture head of the punching device is used to directly penetrate the mulch. This punching method has some hidden dangers, which are not obvious when punching a mulch with a small hole. When it is necessary to punch out In the case of deep mulch holes, use the puncture head to pierce the mulch film directly, and the tear openings of the formed mulch film are irregular and radial. These irregular tea...

[0003] In the prior art, the conventional mulch punching device is used, and the sharp puncture head of the punching device is used to directly penetrate the mulch. This punching method has some hidden dangers, which are not obvious when punching a mulch with a small hole. When it is necessary to punch out In the case of deep mulch holes, use the puncture head to pierce the mulch film directly, and the tear openings of the formed mulch film are irregular and radial. These irregular tear openings are easy to expand when subjected to external forces, for example, for Deeper, the puncture head is rotated to penetrate, but because the tear opening is divergent, the puncture head drives the mulch in contact with it, and then these mulch holes are forced to continue to expand along the radial opening, so that the required regular circular mulch cannot be formed hole
