Abstract

The utility model relates to a multifunctional small size cultivator, which belongs to a small size hand tractor. The power of the multifunctional small size cultivator is 2.5 to 3.6 kv. The whole multifunctional small size cultivator is composed of a diesel engine, a variable speed part, a running part, a ploughshare, a machine frame, an operating hand rack, etc., wherein, the running part is composed of a running driving chain which is connected with the output end of the middle part of the lower part of a variable speed box and a triangular driving and running mechanism which is composed of a front and a rear guide wheels which are positioned on the ground and annular chain caterpillars. The utility model enhances the stability, the high durability and the intensity. The utility model can pass through ridges and can climb on a slope of which angle is less then 45 DEG. The utility model provides mechanical tillage for mountains and hills of extensive countries without tractor roads and replaces the farm cattle. The whole cultivator has a quick gear and a slow gear for running forward and a gear of the speed for running backward. The utility model is used for farming. When the utility model is attached with accessories, the utility model can be also used for pumping the water, beating the rice, supplying the power, transporting objects, etc.

Description

The multifunction micro tiller

A kind of multifunction micro tiller belongs to miniature walking formula tractor.Be used to plow, rake the soil level, draw water, transport, generate electricity, beat rice, abrasive dust etc.Supporting with it engine is 2.5-3.6 kilowatt, is the little agricultural machinery that substitutes farm cattle.

Existing hand tractor, because of can not be by ridge, can not substitute farm cattle, the field that must have tractor road can be used.Closely adopt develop following shortcoming can be arranged by the mini-size tillage machine of ridge: (1) traveling crawler is arranged on complete machine bottom center, and is the bushroller chain mono-track, and is easily stuck by grass, soil during farming, increases friction, loss power, and breaks easily; (2) pass to the crawler belt drive owing to phoresy structure from routine face, it is too low that change gearbox is liftoff, thereby cultivated not dark, can not satisfy the requirement of normal arable land; (3) mini-size tillage machine of existing triangle driven pedrail, though solved the not dark problem of ploughing, but make transfer gear box liftoff too high, the stability of complete machine is too poor, thereby the effort of ploughing.

The purpose of this utility model provides a kind of multifunction micro tiller, and it has solved the problems referred to above, and it is rational in infrastructure, and is light durable, and the desirable ox of doing farmwork for a soldier's family ploughs.

The purpose of this utility model is to realize in the following way:

The multifunction micro tiller, have engine 23, belt 21,

belt pulley

22,20, friction clutch 19, the gearbox 10 that is in transmission connection in turn and the part of travelling, support complete machine frame 7, be assemblied in the frame front end and becomes the ploughshares 1 at 40 degree-50 degree inclination angles to reach fixedly adjustment part and farming arm-rest frame 14 with ground.It is characterized in that: gearbox 10 outputs are connected with loop chain crawler belt drive 9 in the middle of being located at its below, and constituting triangle transmission traveling mechanisms with forward and backward

guide wheel

3,8 and their loop chain crawler belt of outsourcing 4, two loop chain crawler belts are installed on both sides, complete machine bottom and locate the limit most.

Description of drawings:

Fig. 1 multifunction micro tiller structure chart.

Fig. 2 complete machine transmission gear shift structure chart.

Embodiment: see Fig. 1, the multifunction micro tiller, has diesel engine 23,

belt pulley

22,20, belt 21, friction clutch 19, gearbox 10 and gear change hand lever 16, frame 7 and farming handrail 14, ploughshare 1 and pusher dog 27, pull bar 18, operating grip 15, the part of travelling is the crawler belt drive 9 that is connected with output in the middle of gearbox 10 bottoms, before,

back guide wheel

3,8 and the triangle transmission traveling mechanism that constitutes of their loop chain crawler belt of outsourcing, before, back guide wheel 3, be provided with crawler belt supporting plate 6 between 8, article two, loop chain crawler belt 4 arranged side by side, be installed in both sides, complete machine bottom ragged edge and see Fig. 1 and Fig. 2, tooth plate 5 is arranged on the crawler belt, triangle transmission traveling mechanism highest point height overhead has 20-22 centimetre, ploughshare 1 is installed on complete machine foremost, ploughshare top 2 is housed on the frame, on the plowpoing, a guiding mechanism 24 and a left side have a down dip, right-hand rotation axle 25, left and right sides deflection pusher dog 27, pusher dog revolution axle center 26 and pull bar 18, operating grip 15.

See Fig. 3, establish dress driving gear Z on the I in the gearbox ₁, idler gear Z ₂, dress driven gear Z on the axle II ₃, gear Z quickly ₄, driving gear Z at a slow speed ₅, dress duplex driven tooth can Z on the reversing driving gear Zx, axle III ₇, Z ₈, driving gear Z ₉, dress driven gear Z on the axle IV ₁₀, driving gear Z ₁₁, dress carrier gear Z on the axle V ₁₂, dress carrier gear Z on the axle VI ₁₃, dress driven gear Z on the axle VII ₁₄, adorn the drive sprocket 9 that travels, in the rotary tillage transmission case, establish axle and revolve dress driving gear Z on the I ₁₆, driven gear Z ₁₅, and the band one-way clutch, axle revolves dress carrier gear Z on the II ₁₇, axle revolves on the III dress driven tooth Z ₁₈With revolve roller 12, rotary tillage cover 13 is seen Fig. 1.Drive mechanism can be realized Miniature cultivator used on higher travel fast, slow two grades of paces and one grade of back-up speed thus, see Fig. 1, Fig. 2, when if Miniature cultivator used on higher drive rotovator is done mutually, but cracking-off front end ploughshare part, rotary tillage partly is loaded on the back of gearbox 10, revolves the I Z that cogs by the axle IV Z10 connecting axle that cogs ₁₆To realize the rotovator farming.

Advantage of the present utility model: what output connected in the middle of (1) design gearbox bottom travels, Drive sprocket, transmission triangle loop chain crawler belt to reduce bracket height, increase the stability of complete machine, Operate light; (2) the triangle track unit has the 20-22 cm height, can satisfy and plough Dark requirement; Article (3) two, loop chain crawler belt arranged side by side is loaded on both sides, complete machine bottom ragged edge, be easy to discharge mud, Grass can be by mud, careless stuck; The Breadth Maximum of (4) two loop chain crawler belts arranged side by side of crawler belt is 10 Walk by ridge to 13 centimetres of energy, and can climb slope less than 45 degree, can adapt to mountain region, hills, The Plain does not have the vast agricultural district of tractor road, ploughs replacing for mountain region, knob provide mechanical cultivation Ox; (5) complete machine travels and has two grades of paces of speed and one grade of back-up speed, more is suitable for each Plant the farming in soil; (6) ploughshare is at the complete machine front end, the field no dead angle area of all turning over; (7) Ploughshare becomes the inclination angle of 40-50 degree with ground, mud goes out to be easy to skid off from Hua Bi; (8) except ploughing Extraterrestrial, mix annex and can rake the soil level, draw water, beat rice, abrasive dust, generating and transportation etc.
