Abstract

The invention discloses a manual pit digger, comprising: 1) a square frame, in which a first bracket plate is transversally disposed on an upper part of an inner chamber and two second bracket plates are symmetrically disposed on a lower part of the inner chamber in a protruding manner; 2) a lifting bench, which is disposed in the inner chamber of the square frame; 3) a motor arranged on the bottom of the lifting bench; 4) a drill head being connected to the motor; 5) two screw rods, of which the lower parts respectively sleeve the two second bracket plates and the upper parts respectively sleeve the first bracket plate; 6) two threaded holes, which are disposed in the lifting bench and is used for being engaged with the two screw rods; 7) two first gears, which respectively sleeve the upper ends of the two screw rods; 8) a driving shaft, of which the lower end sleeves the first bracket plate and the upper end is stretched out from the top of the square frame; 9) a second gear, which sleeves the lower part of the driving shaft, wherein the two ends of the second gear are respectively engaged with the two first gears; and 10) a handle wheel being arranged on the upper end of the driving shaft. The drill head is lifted or fallen by rotating the handle wheel to drive the lifting bench, so that the manual pit digger is portable and labor-saving and is suitable for common agriculture.

Description

technical field [0001] The invention relates to the field of digging machines, in particular to a manual digging machine. Background technique [0002] At present, in agricultural and forestry planting operations, it is often necessary to use a digging machine. Existing digging machine mostly is suspension type, and it is to hang a digging machine at the rear end of tractor, to move conveniently, and it makes drill bit drive into ground by hydraulic device when digging pit. The hanging digging machine is suitable for large-scale forest farms or farms with convenient transportation. But it is not suitable for ordinary agricultural use, and the existing digging machine is relatively heavy due to the hydraulic device, and it is inconvenient to carry and use alone. Therefore, farmers still dig pits manually, which is labor intensive and efficient Low. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general backgroun...
