Description
(1) technical field
The utility model relates to a kind of hand-push type hydraulic pressure hole digger, belongs to agriculture and forestry machinery field.
(2) background technology
Afforestation, raising green percentage are the fundamental policies that China makes overall plans in process of economic development always.Traditional Tree Planting Earthdrill is connected to the rear end of the main equipments such as tractor, and tractor output shaft output torque drives augers to carry out digging pit operation, there is the shortcomings such as drill bit is not easily located, efficiency is low, operation is inconvenient.Labour intensity is there is large, the high and shortcomings such as footpath limitation of digging pit of fault rate in the portable hole digger course of work.
(3) summary of the invention
For overcoming above-mentioned defect, the utility model provides a kind of hand-push type hydraulic pressure hole digger, be a kind of stable working, labour intensity be low, efficiency is high, simple to operate safe and the novel hydraulic hole digger of footpath adjustable range of digging pit large (300mm ~ 800mm).
The technical scheme in the invention for solving the technical problem is:
A kind of hand-push type hydraulic pressure hole digger, comprises frame, also comprises rack-mounted hydraulic system and mechanical device, augers; Mechanical device comprises trundle, ladder handrail, drill bit protective cover; Hydraulic system adopts existing techniques in realizing.
Fuel tank is set as supporting leg, supporting leg (fuel tank) bottom installation carriage wheel bottom described frame; Described fuel tank doubles as transmission of power liquid---the container of-hydraulic oil.
Described augers is connected with the hydraulic motor of hydraulic system with pin by bearing holder (housing, cover); Described hydraulic motor is pinned in frame by motor base, augers adjustable angle.
Drill bit protective cover is installed outside the augers radius of clean-up; Drill bit protective cover is arranged in frame by the protection shield arm of frame both sides; Protecting shield arm and protective cover and frame all adopts hinged; The anglec of rotation of drill bit protective cover is adjustable, and protective cover can rotate around frame; During operation, drill bit protective cover is rotated to augers peripheral, can safety protection function be played, avoid injuring the person or drill lip.
The oil circuit of described hydraulic system power is provided with overflow reversal valve, exceed setting working pressure by oil circuit pressure and make superfluous hydraulic oil overflow, restriction is played, to ensure that hydraulic system is not undermined operating personnel's safety to system dynamic overload in pit excavation work.
Described ladder handrail is made up of (i.e. uneven bars formula) two stepped armrest up and down connected as one, and two handrails are positioned at a perpendicular up and down successively; Ladder handrail lower end is arranged on frame front end, and ladder handrail whole height is 700mm, wherein: low handrail height is 200mm, high handrail height is 500mm, when drill bit is in shallow brill (0 ~ 300mm) process, apply external force to low handrail, realize drill bit and continue downward drilling; When drill bit is in deep drilling (300 ~ 600mm) process, applies external force to high handrail, realize drill bit and continue to cut to deep drilling and finally complete to dig anti-task.The use of this structure, reduces the angle of bending over of human body in the process of digging pit, and makes that human body is in all the time rationally in whole process of digging pit, comfort conditions.
(4) accompanying drawing explanation
Accompanying drawing 1: the utility model hand-push type hydraulic pressure hole digger structure chart.
Accompanying drawing 2: augers and motor connect view.
Accompanying drawing 3: augers protective cover end view.
In figure: hydraulic pump 1, pump adapter sleeve 2, gasoline engine bracket 3, gasoline engine 4, frame 5, hydraulic oil container 6, protective cover 7, overflow reversal valve 8, oil pipe 9, hydraulic motor 10, motor base 11, handrail 12, drill bit connecting pin 13, augers 14, protective cover swing arm 15, trundle 16.
(5) embodiment
Now be further described the utility model by reference to the accompanying drawings, as shown in Figure 1, the utility model comprises 3 parts: mechanical device, hydraulic system, drill bit.
Described mechanical device comprises: frame 5, hydraulic oil container 6, trundle 16, gasoline engine bracket 3, handrail 12, drill bit protective cover 7, protective cover swing arm 15.Hydraulic oil container had both made the container of hydraulic oil, doubled as again the supporting leg of frame, installation carriage wheel bottom hydraulic oil container, frame, hydraulic oil container, trundle composition dolly; Gasoline engine is fixed in frame by gasoline engine bracket; Ladder handrail is welded in the drill bit of frame, as the handgrip applying external force in bit operation to vertical direction; As shown in Figure 3, drill bit protective cover with frame is mobilizable connects as one by protection shield arm, is protected shield arm and protective cover and frame and all adopts hinged; When hole digger does not work, by rotating protection shield arm, protective cover pull-up being placed in the middle part of frame, during work, by rotating protection shield arm, protective cover being placed in frame leading section, protective action is risen to the drill bit in work.
Described hydraulic means comprises: gasoline engine 4, hydraulic pump 1, pump adapter sleeve 2, hydraulic oil container 6, overflow reversal valve 8, oil pipe 9, hydraulic motor 10, motor base 11.Gasoline engine as hydraulic pressure system power-equipment is connected with hydraulic pump by pump chain female connector (rotating shaft is that shaft coupling connects); Hydraulic pump is by the hydraulic oil press-in oil pipe in hydraulic oil container, and then press-in hydraulic motor, the blade of hydraulic motor is subject to the pressure of the hydraulic oil from oil pipe, motor output revolving shaft is driven to rotate, further, after augers is connected with motor output shaft, drives the rotation of augers, dig pit and be achieved; Overflow reversal valve is arranged at oil pipe midway, is fixed in frame, and the hydraulic oil realizing feeding to hydraulic motor by switch on overflow reversal valve flows to commutation, and then realizes the rotating of hydraulic motor output revolving shaft, realizes digging pit or being backed off by augers; As shown in Figure 2, hydraulic motor is connected in frame by motor base pin (axle), realizes augers fore-and-aft direction adjustable angle.Axle sleeve is connected by drill bit connecting pin with hydraulic pressure drill bit.
The utility model serviceability advantage is remarkable, is embodied as: 1, this device takes hydraulic transmission mode, is digging pit in operation process, transmission efficiency is high, moment of torsion is large, complete machine oscillation is little, noise is little.2, overload protection arrangement is set in hydraulic system, protector is set simultaneously, substantially increase the safety of operation.3, the weight of complete machine is significantly reduced, as: eliminate the main shaft in machine driving, bearing block, reductor, frequency converter etc.4, equipment components can be arranged flexibly in design.5, drill bit drilling angle in the longitudinal direction can regulate, service life of drill bit extends.
