Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are done concrete description: as shown in Figure 1, the portable hole digger of the utility model, comprise level frame holder 1, described holder 1 relative both sides respectively are provided with two horizontal handrails 1.1, frame holder 1 upper fixed is provided with gasoline engine 2, corresponding frame holder 1 below is set with reductor 3, gasoline engine 2 and reductor 3 are connected by shaft coupling, also be provided with the through hole that runs through in the frame holder 1, through hole is provided with thrust bearing, the thrust bearing top also is provided with the coaxial axle sleeve 4.4 that is fixedly mounted in the frame holder 1, axle sleeve 4.4 can play and strengthen degree of fixation and the intensity of drilling rod 4 when frame holder 1 is rotated, drilling rod 4 upper ends are socketed on thrust bearing and the axle sleeve 4.4 successively, drilling rod 4 middle parts are installed with travelling gear, and the gear on reductor 3 output shafts is connected with travelling gear by chain 5.
Drilling rod 4 bottoms are provided with screw blade 4.1, and blade 4.1 thickness are 3-5mm.
Drilling rod 4 lower ends also are provided with location drill bit 4.2, and described location drill bit 4.2 is connected by spline with described drilling rod 4 lower ends and is fixing with alignment pin 4.3.Location drill bit 4.2 cutting edge welding-ons have carbide alloy, have prolonged the service life of boring.
A backguy brake lever 1.2 that is used for control gasoline engine 2 throttles also is set on the handrail 1.1.
Specific embodiment is as follows: at first be the handrail 1.1 that two people hold frame holder 1 both sides respectively, make the location drill bit 4.2 of its drilling rod 4 lower ends be placed on the place that to dig pit, start gasoline engine 2, gasoline engine 2 is given reductor 3 transmission of power by shaft coupling, reductor 3 output shafts are given drilling rod 4 transmission of power again by chain 5, drilling rod 4 rotations, the pulling by control brake lever 1.2 and then control throttle line 1.3 or loosen, reach the size of control gasoline engine 2 throttles, thus the rotating speed of control drilling rod 4.Be provided with the blade 4.1 of certain spiral angle because of drilling rod 4, during blade 4.1 work, under the effect of moment of torsion and axial force, blade 4.1 rotations and the soil of motion cutting vertically downward, cutting soil down along helical blade 4.1 throw the hole around, after burying, just come up by the excavation of blade 4.1 turning handles soil, according to soft or hard and the degree of depth of soil property, the size of control gasoline engine 2 throttles so just can high efficiencyly be finished the operation of digging pit in good time.Because the location drill bit is consumable accessory, adopts replaceable structure, increased the service life of boring, more economical environmental protection.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
