Efficient circumferential root cutting head for seedlings in nursery garden

Abstract

The invention relates to the technical field of root cutting of seedlings in a nursery garden and discloses an efficient circumferential root cutting head for seedlings in a nursery garden. The efficient circumferential root cutting head comprises a drill bit, a cutter body and a rotating mandrel, wherein the cutter body comprises milling cutter sections, the drill bit is designed by simulating the head and neck curve of a pangolin, the milling cutter sections are designed by simulating bombax ceiba trunk, and bombax ceiba spiniform cutters are arranged in a DNA double helix manner; the drill bit and the milling cutter sections are connected and then integrally mounted on the rotating mandrel; a first chip discharge groove is axially processed in the drill bit, and blade slots are processed in the milling cutter sections of the cutter body; the cutters are mounted in the blade slots. First drilling and later milling are adopted, that is, the drill bit drills the soil layer for about one meter, then the spiral milling cutter sections are used for milling the soil layer, and annular or square cutting is completed. By means of the cutting head, the labor intensity and working noise in the root cutting process can be reduced, the labor efficiency is improved, and risk caused by close-range contact of people and the cutters is avoided.

Description

technical field [0001] The invention relates to a root-cutting cutter head, in particular to a high-efficiency nursery seedling circumferential root-cutting cutter head, which belongs to the technical field of forestry seedling tending. Background technique [0002] Saplings are basic resources for forestry development and need to be cultivated and tended. In order to ensure that the seedlings in the nursery do not invade each other and at the same time improve the survival rate after transplanting, the roots of the seedlings need to be trimmed regularly, that is, the excessively long parts need to be trimmed as required. At present, root cutting operations in nurseries are generally done manually using tools such as picks and shovels, which are labor-intensive, consume a lot of manpower, and are inefficient. So some technicians tried to use a device similar to a chainsaw to cut the roots, but this device would deflect when encountering stones during cutting, the operation ...
