Abstract

The invention discloses a hole digger which comprises a support, an oil tank, a hydraulic pump, a power source connected with the hydraulic pump, a vertically arranged hydraulic cylinder, and a reversing valve for controlling the hydraulic cylinder, wherein two lower inclined support rods are arranged on the support, and the lower end of each lower inclined support rod is hinged with a digging shovel; and a piston rod of the hydraulic cylinder is connected with the support, the hydraulic cylinder is fixedly arranged on a connecting block, and two ends of the connecting block are hinged with the two digging shovels. The hole digger provided by the invention is small in size, light in weight, compact in structure, low in price, and very convenient to operate; and the digging shovels are driven by the hydraulic cylinder to dig holes, so that the hole digger is high in speed, high in efficiency, adapted to various terrains, and high in adaptability.

Description

A kind of earth auger
Technical field
The present invention relates to the excavator technical field, relate in particular a kind of earth auger.
Background technology
In the production of forestry, agricultural planting industry, often need to dig out the needed cave of plantation arable land, mountain forest, and, in results, also butt, the bamboo root and stem of certain plants etc. to be taken out, receive the restriction of natural environment, adopt hand digging at the majority that digs the cave now, hand digging, workman's labour intensity is large, renders a service lowly, and the working time is short, and, along with the gradually increase of cost of labor, the cost of hand digging is very high, affects income.And the somebody adopts engineering machinery to dig the cave, such as excavator etc., still, do like this that not only working cost is high, and equipment is huge, in mountain forest ground walking inconvenient, a lot of planting sites disperse, each piece ground area is little, the employing excavator is lost more than gain.
Summary of the invention:
The objective of the invention is provides a kind of earth auger for the deficiencies in the prior art part, and its volume is little, lightweight, simple and compact for structure, processing ease, operating rate is fast, efficient is high, and safety is good.
Technical measures of the present invention are as follows; A kind of earth auger, comprise power source, the hydraulic cylinder that vertically arranges and the reversal valve of controlling described hydraulic cylinder that support, fuel tank, hydraulic pump and described hydraulic pump are connected, described support is provided with two poles that have a down dip, and each described pole lower end that has a down dip is hinged with one and digs shovel; Described hydraulic cylinder piston rod is connected with described support, and described hydraulic cylinder is fixed on the contiguous block, described contiguous block two ends and described two dig the shovel be hinged.
The setting of described two pole symmetries that have a down dip.
Described reversal valve is hand-operated direction valve.
Described power source is connected with described hydraulic pump by shaft coupling.
Described power source is gasoline engine.
The described pole lower end that has a down dip is hinged by jointed shaft and the described shovel that digs.
The described pole lower end that has a down dip is hinged by jointed shaft and the described shovel pars intermedia that digs.
Described contiguous block is hinged by rotating shaft and the described shovel upper end of digging.
Beneficial effect of the present invention is:
A kind of earth auger of the present invention, its volume is little, lightweight, and compact conformation is cheap, and is easy to operate, and it adopts the hydraulic cylinder drive to dig shovel and excavates, and speed is fast, efficient is high, adapts to various landform, strong adaptability.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic diagram of the present invention.
Embodiment
Embodiment sees accompanying drawing 1,2; A kind of earth auger, it is characterized in that: comprise support 1, fuel tank 2, hydraulic pump 3, the power source 4 that is connected with described hydraulic pump 3, the hydraulic cylinder 5 that vertically arranges and the reversal valve 6 of controlling described hydraulic cylinder 5, reversal valve 6 is hand-operated direction valve, the pump discharge of the oil-in of reversal valve 6 and hydraulic pump 3 is communicated with, the pump inlet of hydraulic pump 3 and fuel tank are communicated with, hydraulic oil in the fuel tank is pumped in the reversal valve, and described power source 4 is gasoline engine, for the ease of working in the open air, general power source 4 adopts gasoline engine, being connected axle with hydraulic pump by shaft coupling 10 connects, the rotation of drive hydraulic pump, described support 1 is provided with two poles 7 that have a down dip, the setting of described two pole 7 symmetries that have a down dip, and each described pole 7 lower end that have a down dip is hinged with one and digs shovel 8; Described hydraulic cylinder 5 piston rods and described support 1 are fixedly connected, and described hydraulic cylinder 5 is fixed on the contiguous block 9, and described contiguous block 9 two ends and described two dig shovel and 8 are hinged.
Described fuel tank 2, hydraulic pump 3 and power source 4 are arranged on the described support 1, described reversal valve 6 is arranged on the described fuel tank 2, to reduce volume, described hydraulic cylinder 5 vertically is fixed on the described contiguous block 9, two actuator ports of two hydraulic fluid ports of hydraulic cylinder 5 and reversal valve are communicated with, so that the lifting of reversal valve control hydraulic cylinder 5.Described pole 7 lower ends that have a down dip are hinged by jointed shaft 11 and the described shovel 8 that digs, and are better, and described pole 7 lower ends that have a down dip are hinged by jointed shaft 11 and described shovel 8 pars intermedias that dig, and described contiguous block 9 is hinged by rotating shaft 12 and described shovel 8 upper ends of digging.
