Abstract
An external discharge layered pit digger comprises a rack, a transmission case, a universal joint, a spiral pit digging device and a layered soil discharge device, wherein the rack comprises a lifting disc, an upper pull rod and lower pull rods; the layered soil discharge device is positioned at the bottom of the spiral pit digging device and at the periphery of the spiral pit digging device; the layered soil discharge device comprises an inner barrel, an outer barrel, inner barrel hanger rods, outer barrel hanger rods and lugs; and the inner barrel and the outer barrel are cylinders with two opened ends. When the digger operates, the spiral pit digging device does not dig downwards; topsoil is brought out by spiral blades and falls into an interlayer between the inner barrel and the outer barrel; after the interlayer between the inner barrel and the outer barrel is fully filled, raw soil falls on the ground on the outer side of the outer cylinder; when the digging operation is finished, and the lower pull rod drives the lifting disc to be lift upwards, the inner barrel is lift first; and at this moment, the topsoil in the interlayer between the inner barrel and the outer barrel just falls on the inner side of the raw soil; after a seedling is planted, the topsoil can be pushed into a tree pit conveniently, so that the purpose of allowing fertile soil to be positioned at the root of the seedling and raw soil to be positioned above the fertile soil is achieved.
Description
technical field:
