Description

The hand-held type multifunctional tractor

The utility model belongs to a kind of walking tractor, is particularly suitable for the transportation and the field farming in mountain area, hills, terraced fields, gorge narrow road section and farmland.

At present, the machinery that is used for agricultural transportation and field management mostly adopts the trac. of two-wheeled at least, these trac.s are owing to taken turns many influences, machine volume is big, and weight is heavier, and corner turning difficulty is big, very flexible, so can only transport or few a part of field farming at region of no relief, and to not transporting and multinomial purpose field management operation in those mountain areas, the uneven haggard in hills and arrow path road, gorge, so range of use is little.

It is strong that the purpose of this utility model provides a kind of alerting ability, the hand-held type multifunctional tractor that range of use is wide.

The technical solution of the utility model is: include frame, engine bed on the frame, rack-mount driving engine, on frame, be fixedly connected with bar handle, detachable drawbar frame is installed in frame and below bar handle, drawbar frame is connected with trailer through coupling hitch, in frame one side change speed gear box is installed also, it is characterized in that being equipped with by the walk alone wheel of driving engine below the frame by actuator drives, the random fixed support is housed on frame, also the variety classes agricultural machinery and implement can be installed as required on the random fixed support.

Compared with similar products, the utility model has adopted a road wheel, be connected with two-wheeled trailer machine, walking is convenient, and alerting ability is strong, when carrying out the field farming, can also pull down trailer from coupling hitch, on the random fixed support, the variety classes agricultural machinery and implement are installed as required then, thereby enlarged field of application, improved production efficiency.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is equipped with lift pump or farm chemical spray pump integral structure meaning diagrammatic sketch for the utility model;

Fig. 2 pulls down birds-eye view behind the lift pump for Fig. 1;

Fig. 3 pulls down trailer structural representation when the farming of field for the utility model;

Fig. 4 for the utility model pull down trailer field fertilization or when sowing structural representation;

Fig. 5 is the utility model coupling hitch birds-eye view;

Fig. 6 is the cutaway view along A-A line among Fig. 5.

From the utility model embodiment illustrated in figures 1 and 2 as can be seen, organic frame 17, engine bed 19 on the frame 17, be installed in the driving engine 1 on the support 19, on frame 17, be fixedly connected with bar handle 6, detachable drawbar frame 13 is installed on frame 17 and below bar handle 6, drawbar frame 13 is the firm frame of 3-D triangle, drawbar frame 13 is connected with trailer 10 through coupling hitch 12, the side that connecting device 12 includes link span 36 is captiveed joint by cylindrical pins 37 with drawbar frame 13, the chassis of opposite side and trailer 10 flexibly connects by slewing arrangement 38, and slewing arrangement 38 respectively is equipped with bearing 39 up and down and (sees Fig. 5, Fig. 6).The driving engine 1 that is installed on the engine bed 19 is transferred to flower wheel 2, flower wheel 2 is transferred to change speed gear box 16 through master clutch 23, the wheel 18 of walking alone on change speed gear box 16 output shafts 30, random fixed support 20 is housed on frame 17, lift pump or farm chemical spray pump 29 are installed on the random fixed support 20, below frame 17, also are equipped with and support backplate 22.

During hauling operation, drawbar frame 13 is fixed on the frame 17, be connected with trailer 10 through coupling hitch 12 again, the wheel 18 of will walking alone this moment is enclosed rubber layer on the outside face of former iron tyre, this rubber layer can be fastened on rubber layer on the iron tyre with bolt, be beneficial to alleviate the iron tyre vibration, be convenient to transportation, the arrangement for adjusting height 14 adjusting bar handles 6 that are equipped with on the frame 17 by adjusting are proper height at last, control apparatus 14 is divided into height, in, low third gear is regulated, to adapt to the different work requirement for height, easy to use for the ease of instrument, tool box 5 is housed on bar handle 6, chaufeur operator's saddle 31 is arranged on the trailer 10, be used to control the brake pedal 11 of brake gear.The power of driving engine 1 drives the walking alone wheel 18 that is installed on this through flower wheel 2, master clutch 23, power wheel 24 to the output shaft 30 of change speed gear box 16 and walks, and drives trailer 10 simultaneously and walks.The clutch of master clutch 23 is to realize stopping and rotating by being installed on the bar handle 6 master clutch manipulating handgrip 9 control master clutch steering units 8.The speed of travel of trac. is by the 4 shifted walkings of moveing backward of the gear-change hand lever on the change speed gear box 16 that is installed on the mainframe 17.

(see figure 3) during field farming operation, at first trailer 10 is pulled down at coupling hitch 12 places, the drawbar frame 13 that will be fixed on again on the frame 17 is pulled down, load onto farm implements hanger bracket 25, pull down the rubber layer of walking alone above the wheel 18 this moment, because iron tyre is adapted to farm work, farm implements hanger bracket 25 is regulated bolt 32 with mainframe 17 usefulness and is flexibly connected, in farm implements suspension 25, track adjusting wheel 27 is installed, track adjusting wheel 27 is the scalable weight, can play equilibrium activity again, the lifting of farm implements hanger bracket 25 is to be handled by the bar handle 3 that is installed on the frame 17, rises when road is walked, and puts down when the farming of field, hang at farm implements as required single plow 26 is installed on 25, can carry out cultivation operation; The weeding Stubble cleaner is installed, is carried out weeding, stubble-cleaning, the operation of ploughing, loosen the soil; The ditching ridge device is installed is carried out the ditching ridge operation; Installation an animal-drawn seed plough angle can be sowed, the operation of applying fertilizer.Walk alone wheel 18 walkings as previously mentioned, be installed in throttle control hand lever 8 on the handgrip and be used for controlling throttle speed adjusting plate 21 on the driving engine 1.
