Description
Technical field:
The utility model relates to a kind of tree well machine that digs, and especially relates to a kind of screw and digs the tree well machine.
Background technology:
Still also do not have at present a kind of plant equipment of digging tree well that is specifically designed to, when planting trees, usually will manually dig tree well, operating efficiency is low, has brought inconvenience for large-area afforestation, especially for the peasant household that contracts conceding the land to forestry, plant trees in the large tracts of land deserted mountain, caused many difficulties.
The utility model content:
It is a kind of simple in structure and tractor with small four wheels is matching used, efficient is high, power consumption is low, bore hole standard, one man operation that the purpose of this utility model is to provide, and economizes the merit labour-saving and dig the tree well machine.
The purpose of this utility model is implemented by following technical scheme: the transmission mechanism that it includes actuating unit, the gearbox that links to each other with the actuating unit output shaft, links to each other with output shaft of gear-box, described transmission mechanism include cone pinion, with the cone pinion output shaft mutually interlock large bevel gear, place in the middle of the described large bevel gear the vertical square shaft with described large bevel gear interlock; Be provided with the transmission mechanism cover in described transmission mechanism outside, be provided with leading screw on described square shaft top, be provided with the nut that coincide with described leading screw in described leading screw outside, described nut is fixedlyed connected with described transmission mechanism cover, is provided with the drill bit device in described square shaft bottom.
Described actuating unit includes minor sprocket, chain, hinge wheel, the hinge wheel output shaft that links to each other with the power take-off of carriage, and described minor sprocket links to each other with described hinge wheel by described chain, and the hinge wheel output shaft links to each other with described gearbox.
Described gearbox is provided with the speed Control bar.
Be provided with support at described gearbox and transmission mechanism cover bottom.
Described drill bit device includes drill sleeve, drill bit, drill lip, in described drill sleeve, be provided with and described drill bit fixed reamer head dead lever, below described drill bit dead lever, be provided with pressure bearing, on described drill bit dead lever, be provided with hangnail, accordingly be provided with on the described drill sleeve inwall with described on the hangnail corresponding following hangnail that coincide; Front end at described drill bit is provided with described drill lip.
The utility model has the advantages that: the supporting use of simple in structure and tractor with small four wheels, its efficient height, power consumption be low, bore hole standard, one man operation, province's merit is laborsaving, on harder soil, per hour can bore 80-100 hole, the hole deeply can be according to the length of drilling rod, and the hole degree of depth is different with the hole diameter length, and it is artificial 8-10 times.
The drawing explanation of accompanying drawing:
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of large and small gear interlock.
Fig. 3 drives the structure diagram that digs the tree well machine for four-wheel tractor.
Embodiment:
Embodiment 1: dig the transmission mechanism 4 that the tree well machine includes actuating unit 1, the gearbox 2 that links to each other with actuating unit output shaft 12, links to each other with output shaft of gear-box 3, transmission mechanism 4 include cone pinion 5, with cone pinion output shaft 6 mutually interlock large bevel gear 7, place in the middle of the large bevel gear the vertical square shaft 8 with large bevel gear 7 interlocks; Be provided with transmission mechanism cover 9 in transmission mechanism 4 outsides, be provided with leading screw 16 on square shaft 8 tops, be provided with the nut 10 that coincide with leading screw 16 in leading screw 16 outsides, nut 10 overlaps 9 with transmission mechanism fixedlys connected, and is provided with drill bit device 11 in square shaft 8 bottoms.Actuating unit 1 includes minor sprocket 13, chain 14, hinge wheel 15, the hinge wheel output shaft 12 that links to each other with the power take-off 17 of carriage, and minor sprocket 13 links to each other with hinge wheel 15 by chain 14, and hinge wheel output shaft 12 links to each other with gearbox 2.Gearbox 2 is provided with speed Control bar 18.Overlap 9 bottoms at gearbox 2 and transmission mechanism and be provided with support 19.Drill bit device 11 includes drill sleeve 20, drill bit 21, drill lip 22, in drill sleeve 20, be provided with and drill bit 21 fixed reamer head dead levers 23, below drill bit dead lever 23, be provided with pressure bearing 24, be provided with hangnail 25 on the drill bit dead lever 23, on the drill sleeve inwall, be provided with accordingly and last hangnail 25 identical corresponding following hangnails 26; Front end at drill bit 21 is provided with drill lip 22.
Power transmission process: the power take-off of carriage passes to gearbox by large and small sprocket wheel, chain, passes to large and small bevel gear by output shaft of gear-box again, drives the square shaft rotation.Because the square shaft top is the nut screw structure, so square shaft except radially rotating axial force takes place also,, drill bit is buried even produce downward pressure during whole vertical shaft (including square shaft, leading screw, drilling rod) forward rotation, reversing then makes drill bit propose outside the hole.A pair of upper and lower hangnail is arranged in the drill sleeve, produce pressure because drill bit contacts with ground when clockwise, make upper and lower hangnail interlock, drill bit cutting soil, when soil is carried in counter-rotating, propose with the resistance of drill bit is smooth for soil being let out down because of counter-rotating and being alleviated soil, upper and lower hangnail will lose interlocking because of lifting force, then square shaft is transferred drill bit does not change, drill bit proposes ground by pressure bearing under sliding naturally, even do or wet soil, also easily propose outside the hole.Cutting of the power of drill bit device and dynamics conversion, because the transmission of actuating unit is the transmission by carriage, thus ought depress in the clutch of carriage, by several functions of gearbox itself: three drive shifts, a reverse gear, a neutral gear.Three drive shifts can be respectively to the selection regulation and control soft, that hard place carries out suitable dynamics, carry out the speed adjustment simultaneously and alleviate load to engine.During neutral gear, vertical shaft does not rotate, bored a hole after, step in the carriage clutch, gearbox is placed carries soil shelves, drill bit then proposes ground fast.Then the speed Control bar is put neutral gear, step on carriage clutch operating carriage and exercise forward,, stop and bore the hole to the next hole point that bores.Verified, on harder soil, per hour can bore 80-100 hole, be artificial 8-10 times, the efficient height, it is low to consume energy, and bores the hole standard, the one man operation, it is laborsaving to economize merit.
