Earth auger for agroforestry planting

Abstract

The invention discloses an earth auger for agroforestry planting. The earth auger comprises a support plate, a motor, handles, hydraulic cylinders and supporting legs. Lower ends of the supporting legs are fixedly connected on piston rods of the hydraulic cylinders. Lower ends of the hydraulic cylinders are fixedly provided with shock pads. Lower surfaces of mounting bases are provided with several antiskid spines. The lower end of a spindle is fixedly provided with a tip. The spindle above the tip is fixedly provided with spirally-arranged digging vanes. The support plate is fixedly equipped with a water tank. The bottom of the water tank is communicated with a shower pipe which is provided with a solenoid valve. Left and rights ends of the support plate are respectively provided with the handles which are upswept. The upper end of each handle is provided with a control button which is connected to the solenoid valve through a lead. The device of the invention has a simple structure, operates stably and is convenient to carry. By the device, labor force is saved, and digging efficiency is raised. The device is time-saving and labor-saving, can be suitable for digging of dry and hard soil, has a wide range of application and has long life.

Description

technical field [0001] The invention relates to an agricultural and forestry machine, in particular to a pit digger for agricultural and forestry planting. Background technique [0002] At present, in the process of agricultural and forestry planting, digging tree pits is mainly done by manpower. The digging efficiency is low and irregular, and for hard soil layers and frozen soil layers, it is very difficult to dig by manpower. There are also some pit digging machines used to replace manpower digging pits. However, due to the structural defects of the existing pit digging machines, they can only be driven by small vehicles (such as four-wheeled vehicles), which have poor applicability and digging efficiency. Low, difficult to promote, can not completely replace manpower digging, and in some mountainous and hilly areas, vehicles cannot be driven up the mountain for agricultural machinery operations, which will bring certain losses to users. In the process of digging, sometim...

Problems solved by technology

[0002] At present, in the process of agricultural and forestry planting, digging tree pits is mainly done by manpower, which is inefficient and irregular, and it is very difficult to dig by manpower for hard soil and permafrost

Now some digging machines are also used to replace manpower digging, but because the existing digging machines have certain defects in structure, they can only be driven by small vehicles (such as four-wheel vehicles, etc.), which have poor applicability and low digging efficiency. Low, difficult to popularize, and cannot completely replace manpower digging, and in some mountainous and hilly areas, vehicles cannot drive uphill for agricultural machinery operations, which will bring certain losses to users. In the process of digging, sometimes encounter In areas with dry and hard soil, the soil needs to be moistened before digging
