Abstract
The utility model relates to a micro tractor for farming in mountain lands, which is a micro cultivator. The utility model comprises the whole structure of an existing walking tractor, a worm wheel worm rod reducer is additionally arranged behind a belt pulley clutch assembly based on the structure, a differential device is additionally arranged in a central transmission box, a right braking ring and a left braking ring are additionally arranged on wheel shafts of driving wheels, and an interlocking mechanism is additionally arranged at the opposite ends of a left driving wheel shaft and a right driving wheel shaft. The micro cultivator has the advantages of large torque and flexible turn. The micro cultivator can turn in a forward direction and is especially suitable for work, such as first tillage, rotary tillage, leveling, furrow, pumping, etc., in the positions, such as mountain areas, hills, orchards, the inner parts of greenhouses, and small fields.
Description
Technical field
The utility model relates to a kind of tractor, the miniature walking harvesting and tillage machine that the farming of particularly a kind of mountain region is used, both mini-size tillage machine.
Background technology
Existing mini-size tillage machine series of products substantially all belong to old-fashioned hand tractor project organization, only change to be that power is joined little, volume-diminished, gear reduces, and their drive connection and steering operation mode do not change, still take left and right sides dental forceps to break away from and turn to, reverse operating is opposite with people's idea.The peasant realizes that to sloping road reverse operating the mode of turning is difficult for grasping in operation is travelled, be easy to cause the steering operation mistake, has an accident, and especially begins to learn the driver and is afraid of this point most, and this is to have common problem small-sized and that the miniature walking harvesting and tillage machine exists now.
Technology contents
The purpose of this utility model is the mini-size tillage machine that proposes a kind of low velocity that is suitable for using in the mountain region, high pulling torque, at any time can both positive operation turns.
The technical scheme that realizes above-mentioned purpose is as described below:
It comprises whole structures of existing hand tractor, on the basis of its structure, promptly after the belt pulley clutch assembly, installed a worm type of reduction gearing additional, in central transmission case, installed a differential mechanism additional, on the wheel shaft of driving wheel, installed a right brake hoop and left brake hoop additional, about two live axle opposite ends installed an interlocking gear additional.
Through the change of said structure, the moment of torsion of common mini-size tillage machine is increased, turn arbitrarily flexibly, and can turn by positive operation.
Description of drawings
Fig. 1 is the Facad structure schematic diagram of mini-size tillage machine described in the utility model.
Fig. 2 is the backsight structure chart of mini-size tillage machine described in the utility model.
Among the figure: 1, frame, 2, diesel engine, 3, the V-belt, 4, the belt pulley clutch assembly, 5, worm type of reduction gearing, 6, driving-chain, 7, gearbox, 8, differential mechanism, 9, final transmission case, 10, driving wheel, 11, hand steered, 12, clutch handle, 13, clutch pull rod, 14, gear lever, 15, clutch separation pawl, 16, right brake hoop, 17, two driving wheel interlocking mechanisms, 18, left brake hoop, 19, interlocking mechanism's shift fork handgrip, 20, central transmission case.
Below in conjunction with Figure of description the utility model is described further:
As depicted in figs. 1 and 2, mini-size tillage machine described in the utility model comprises frame 1, diesel engine 2, V-belt 3, belt pulley clutch assembly 4, driving-chain 6, gearbox 7, final transmission case 9, driving wheel 10, hand steered 11, clutch handle 12, clutch pull rod 13, gear lever 14, clutch separation pawl 15, interlocking mechanism 17, interlocking mechanism's shift fork handgrip 19 and central transmission case 20.It is the improvement of doing on the basis of " Changzhou--12 type hand tractors ".Promptly after belt pulley clutch assembly 4, installed a worm type of reduction gearing 5 additional, in central transmission case 20, installed a differential mechanism 8 additional, on the wheel shaft of left and right sidesing driving wheel 10, install a brake hoop 16 and 18 respectively additional, installed an interlocking mechanism 17 in the opposite end of two live axles additional.
The worm screw left end of worm type of reduction gearing 5 has spline, and belt pulley and clutch assembly 4 and clutch separation pawl 15 are installed, and stage casing and end have bearings, and two bearings is the worm screw active section in the middle of supporting.Belt pulley rotates and makes clutch be given worm screw transmission of power by moving plate through spline, worm screw is rotated and drives the worm gear rotation, the worm-wheel shaft outer end is equipped with sprocket wheel, transmission of power is given the power shaft of gearbox 7 by chain, obtain (3+1) different gears by shifting gear adjustment in the gearbox, make power pass to output shaft, pass to cone pinion by output shaft by gear, and drive the large bevel gear rotation, the incorporated differential mechanism of differential gear set is installed on the large bevel gear.Be separately installed with two spline semiaxis on the gear internal spline of the left and right sides of differential mechanism 8, two driving wheel power are split up into two-way thus, promptly left road and right wing.For increasing the complete machine road clearance, further slow down to increase and turn round, so increased both sides final drive gear case 9 again, power is defeated by left and right sidesing driving wheel by two jack shafts.When two-wheeled is subjected to resistance identical, drive forwards synchronously, at this moment differential mechanism unitary rotation, not differential.If certain on one side driving wheel to be subjected to resistance to rolling too big, then do not rotate (n=0), then another side driving wheel original place is with 2 times speed idle running (skidding), at this moment, complete machine does not advance.For overcoming this phenomenon of being obstructed in short-term, then available interlocking mechanism shift fork handgrip 19 is stirred interlocking mechanism 17, is one with two driving wheel shaft locks, can make this moment the wheel torsion of rotation drive the driving wheel do not rotate also rotates, two-wheeled drives simultaneously and overcomes resistance in short-term, and obstacle detouring advances, behind obstacle detouring, can untiing interlocking makes two-wheeled each is self-driven, help the direct of travel adjustment, otherwise long-term interlocking can't be realized turning to.Be the complete machine braking when left and right sides brake hoop is braked simultaneously, one side brake is then realized the forward turning.
Because worm screw has the effect of reverse latching characteristics and forward turning mechanism to worm gear, make this mini-size tillage machine operation noninertia that travels, more safe and reliable.
Mini-size tillage machine described in the utility model mainly is applicable in the mountain area, hills, orchard, booth, primary cultivation, rotary tillage, the leveling of croft, operation such as ditch, draw water.
