Pit digging machine for populus euphratica planting in arid soil area

Abstract

The invention discloses a pit digging machine for populus euphratica planting in an arid soil area. The machine structurally comprises a fixing frame, an extension frame, a sleeve ring, a driving motor, a soil digging column, spiral stirring pieces, a digging head, a loosening and tightening ring and a hydraulic rod, wherein a bottom nail of the extension frame is connected above the fixing frame,and the top of the sleeve ring is electrically welded below the top of the extension frame. According to the pit digging machine for populus euphratica planting in the arid soil area, after the pit digging machine completes pit digging, the machine is not pulled out of soil, but the driving motor is started to enable the machine to rotate reversely to output reverse current to enable an electromagnet to change the magnetic field direction thereof, a soil expanding rod is pushed out, an advancing and retreating rod is pushed out and inserted into an obliquely downward place in a bottom pit, meanwhile, relatively moist air is output through a soil loosening hair needle and a water expanding cavity so as to enable the periphery of the soil to become looser, populus euphratica can take root better after planted, the root system can stretch downwards more easily, and the populus euphratica is easier to survive.

Description

technical field [0001] The invention relates to a digging machine, in particular to a digging machine for planting Populus euphratica in dry soil areas. Background technique [0002] In the desolate areas of the Northwest, sand is blowing all the year round, and due to the large area, the strong wind often brings the wind and sand. It is necessary to plant wind-resistant trees such as Populus euphratica. In the pits planted on the surface, after Populus euphratica takes root, it needs strong vitality to take root to find water sources. For some trees with poor vitality, they cannot survive, and the root system is difficult to extend to find water sources. The current technical considerations are not comprehensive and have the following disadvantages: [0003] When the pit planer finishes digging the hole, it can only dig out the pit on the surface to accommodate Populus euphratica, and does not treat the soil at the bottom. The soil at the bottom remains relatively dry and f...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the invention is to provide a planer for Populus euphratica plantation in arid soil areas, so as to solve the problem that the planer can only dig out the pits on the surface to accommodate Populus euphratica when the pit is planed. Without treatment, the soil at the bottom will always remain relatively dry and firm, making it difficult for Populus euphratica to take root after planting, which is not conducive to the branching of the roots of Populus euphratica
