Description

The hydraulic drilling tree planter

One, affiliated technical field

The utility model relates to a kind of and the matching used hydraulic drilling tree planter of excavator (trencher).

Two, background technology

General dig pit artificial, trencher commonly used or the mechanical type of planting trees executed and turned hole digger etc.During labour cost, effort, cost is high, efficient is low, can't operation if run into hard soil layer and frozen soil layer; It is not up to standard that the general degree of depth is cheated in the tree planting that trencher digs, the shape irregularity; Existing executing turns hole digger and adopts mechanical drive mode more, and the device that power is provided also mostly is the farming equipments such as tractor, though adopt the tunneling method of bit to excavate, but it is because the restriction of the kind of drive (for example by the main frame transmission shaft driven), most cases is because unstable working condition has caused the drawbacks such as power output deficiency, can not carry out the high pulling torque rotation, can only be at the comparatively soft Ground Operation of soil layer, can not under abominable working environment, carry out continuously work, perhaps fully can not be in frozen soil layer and complicated soil layer (the especially soil layer of rock distribution comparatively dense) work.The diameter of drill bit common also less (being commonly about 0.5m).Plant trees general winter in the northern area of China, and the above-mentioned operating type of digging pit all is subject to the restriction in season.

Three, summary of the invention:

It is low, simple in structure that the purpose of this utility model provides a kind of cost of manufacture, can be applicable to the hydraulic drilling tree planter than hard stratum.

The technical solution adopted in the utility model is: the hydraulic drilling tree planter comprises drill bit and gear-box, at gear-box link is arranged, the utility model is installed hydraulic motor and reductor at gear-box, the gear of hydraulic motor in reductor driven gear case, the pipeline road connecting excavator hydraulic system of hydraulic motor.

The utility model and excavator support the use, having solved the excavation on hard soil layer, frozen soil stratum, is the new product of developing for the special operation environment of planting trees winter, takes into full account the matching with main frame, have simple to operate, safe and reliable, production efficiency is high, the advantages such as easy maintenance.Be best suited for the large tracts of land afforestation, effectively reduced cost, improved production efficiency.The diameter range in the hole of digging pit also can reach more than the 1m.

The utility model is to provide hydraulic power by the excavator main pump to motor, makes power supply more stable; High power hydraulic motor driving reductor slows down, and then by gearbox drive, realizes high pulling torque output at bit part.The gear-box volume also strengthens accordingly, is the large gear of high load capacity in the casing, and the final drive shaft diameter also strengthens thereupon, for high moment of torsion output provides Reliable guarantee, makes its running status more stable.The utility model can be connected with various model excavators, and the scope of application is wider, and it is also more convenient to install; When adjusting angle of drill bit, the regulating mainly with half manual mode of tractor form, and the utility model is to regulate by the bucket cylinder of excavator.

Four, description of drawings

Fig. 1 is connected executing of use and turns the hole digger schematic diagram for existing with tractor;

Fig. 2 is structural representation of the present utility model.

Five, embodiment

The boring equipment of digging pit on the market is that the engine 5 by tractor 6 provides power, the final drive shaft 4 of tractor 6 directly drives and drill bit 1 rotation to gear-box 2 transmissions through take-off (propeller) shaft 3, its gear-box that adopts 2 volumes and final drive shaft 4 diameters are less, can't realize high pulling torque output, when excavating frozen soil layer, easily cause power transmission shaft to damage.

The utility model is to pass through reductor 8 uni-drive gear boxes 2 by hydraulic motor 7, and gear-box 2 drives drill bits 1.The major impetus input unit is the hydraulic motor 7 that places reductor 8 tops, needs when mounted power shovel is unloaded in advance, then gear-box 2 of the present utility model is connected with the excavator forearm by link 14; Supporting excavator is a subsidiary cover hydraulic oil pipe at random, is used for providing for optional equipment in the connecting excavator system device of power.The utility model and excavator coupling part are normal structure, also can make corresponding adjustment according to excavator bucket capacity and position to the processing of gear-box 2 in advance according to actual conditions.

Have in the gear-box 2 of the present utility model with the coaxial pinion that is connected 9 of reductor 8 output shafts and with the gear wheel 13 of pinion 9 engagement, gear wheel 13 and main shaft 11 and 1 coaxial connection of drill bit.In pinion 9 axle bottoms cylinder roller bearing 10 is arranged; Self-aligning roller bearing 15 is arranged at the main shaft top on gear wheel 13; At main shaft 11 middle parts and bottom taper roll bearing 12 is arranged.

After correct connection the with oil circuit, excavator can provide hydraulic power to the utility model, drive hydraulic motor 7 and drive reductors 8, and then the interlock by the pinion 9 in the gear-box 2 and gear wheel 13 with power transmission to main shaft 11; Because the utility model has been selected high-quality hydraulic speed reducer according to calculating on the spot, so intrasystem deceleration ratio is able to accurately and reliably; And the kind of drive that the pinions 9 in the gear-box 2 drive gear wheels 13 has been guaranteed in the situation that high pulling torque output stable and reliable, guarantees that the utility model can be in the headwork high efficient and reliable of abominable working environment (as: winter frozen soil layer and the soil layer of some rock distribution than comparatively dense in); By comparison, like product can't reach this requirement in the situation that rely on transmission shaft driven to turn round fully, especially in the comparatively abominable the Northeast of environment.

After gear-box partly is installed to excavator, start excavator and determine that power output arrives in the situation that hydraulic motor 7 and body work well fully, drill bit 1 is connected to main shaft 11 front ends, determine that connection reliably can construct.

The sealing condition of gear-box of the present utility model 2 inside also adapts to long-time high-load operation fully; And aspect the leakage of avoiding gear oil, carried out equally major tuneup, consider how can change more easily gear oil in the cabinet design process, be chosen in the most reasonably and installed oil transportation hole and drain oil additional on the position, more convenient and swift when guaranteeing to change gear oil; Secondly also be able to perfect after the joining of gear-box 2 and main shaft 11, the part of main shaft 11 in casing adopts " 3 points " fixed form, that is: two taper roll bearings 12 have been added at front-end of spindle, and selected self-aligning roller bearing 15 at its end, and increased accordingly the length of main shaft 11, in work progress, guaranteed the stability of main shaft 11, offset most of owing to revolving the axial and radial load that 1 pair of main shaft 11 of drill bit brings in the process of digging, avoided because the injury that main shaft causes other parts because the amplitude of oscillation is excessive in the course of the work, increase the whole service life of mechanism, delayed the maintenance cycle of product.Drill bit 1 is selected the quality steel plate manufacturing fully, and has installed high-quality high-abrasive material additional at drill bit 1 front end, has increased the service life of rotary head, and the bucket tooth of chisel edge is changed convenient.
