At present, the afforestation in the hilly areas in the south of China is still a very hard work. The main reason is that the mountain is high and steep, and a common large-scale pit digging machine cannot be unfolded and can only dig a pit and plant a tree by manpower. Therefore, the labor intensity of afforestation operation is high, the efficiency is low and the cost is high. In order to reduce the labor intensity of afforestation operation, improve the production efficiency and reduce the production cost, a portable mountain earth boring machine with strong practicability is urgently needed to replace manual earth boring operation. Although some slight portable earth boring machines using a miniature gasoline engine as power have appeared on the market, the design concept is mainly designed for the earth boring operation of relatively flat and slow terrains such as farmlands, gardens, orchards and the like, so the earth boring machine can not meet the operation requirement of steep slopes in forest zones in terms of performance, and the defects are mainly represented in that 1) the whole machine is supported by a single wheel, the stability is poor, the earth boring machine is easy to topple, the earth boring machine is not easy to control and balance during earth boring, and a drill bit is easy to damage; 2) the wheels are too small, the obstacle-crossing capability is poor, and the walking in the cut land is difficult; 3) when digging a pit, the user must bend down to press the pit downwards with two hands, and the pit can not be operated with one upright hand, which is very inconvenient.
For example, patent application No. CN201410269675.6 discloses an electric earth boring machine, comprising: a tripod frame, comprising: the three vertical rods are distributed in a triangular manner, and the plurality of cross rods are used for connecting the three vertical rods, wheels and handles are arranged on the rear side face of the triangular rack, and three support legs are arranged at the bottom of the triangular rack; a sliding support, comprising: the guide rods are fixedly arranged on the triangular frame; the support is provided with a plurality of sleeves which are respectively sleeved on the guide rods; the lifting mechanism is connected with the support to drive the sliding support to lift; the power mechanism is arranged on the support and comprises: a storage battery; a motor powered by the battery; and a speed reducer connected with the motor; and the spiral drill rod is connected with the speed reducer. Also, for example, patent application No. CN201721213943.8 discloses a small mountain land flat gear rack earth boring machine, which comprises a frame, an engine assembly, a drill bit and a lifting mechanism, wherein the engine assembly comprises an engine and a transmission matched with the engine, the lifting mechanism comprises a rack, a gear and a handle arranged on a gear shaft, the gear and the rack are in meshing transmission, the drill bit is arranged on an output shaft of the engine assembly and driven, the engine assembly is arranged on a drill bit seat, the drill bit seat is arranged on the rack and a guide rod of the lifting mechanism to ascend and descend, the guide rod and the lifting mechanism are arranged on the frame, a pair of casters is arranged on rear support legs of the frame, two front support legs are telescopic support legs, the toe is a cone head, and a turning positioning pedal is arranged at the rear part of the frame. The earth boring machine in the above scheme alleviates the labor intensity of manual earth boring to a certain extent, and is portable to a certain extent, but still has some shortcomings more or less, and adaptability is poor, can not be fine use widely on the abrupt slope of forest district.
