Abstract

The utility model relates to a small-sized power-driven cultivator. The external shape of the small-sized power-driven cultivator is similar to that of a hand tractor, but the structure of the small-sized power-driven cultivator is simpler than that of the hand tractor. The utility model uses an air-cooled diesel engine with 3 to 5 horsepower to as a power source, the power is transferred to a driving shaft through a driving box, a square shaft can be correspondingly inserted in a hollow square hole of the driving shaft, both ends of the square shaft can be provided with driving wheels or a rotary cultivating knife tackle, and then the utility model carries out agricultural implement drawing or rotary cultivating operation. The utility model can enter ridges (such as corn, cotton, cabbage, etc.) with small space to carry out cultivating, weeding, banking, fertilizing, etc. operation, and realizes the action of replacing animal power and manpower.

Description

Small-sized power-driven cultivator

The utility model relates to a kind of agricultural machinery.

Be operation between the ridge in the field management of China's height, king-rod crops (as corn, cotton etc.) (as loosen the soil, events in operation such as weeding, ridging, fertilising) at present, because its distance between the ridges is from less, be generally less than 60cm, various tractors all can not enter operation therebetween, so can only finish above-mentioned operation by animal power or manpower at present.

The purpose of this invention is to provide and a kind ofly can replace animal power and manpower, carry out the minitype motivation cultivator of operation between the ridges of height, king-rod crops.

It is 3～5 horsepowers of air-cooled diesel engines that the utility model is selected power for use, and its power drive system is with general hand tractor.Can divide upper and lower two parts in the gearbox of the present utility model, be the variable part in the upper box body 1, basic identical with common hand tractor variable part; The utility model key is the final running part 2 of lower part, there is jackshaft 12,13,14 directly to be bearing on the transmission case body respectively, all use the sealing of " O " RunddichtringO, gear 6 is bearing on the jackshaft 14 by two ball bearings,

gear

7,8 is bearing on jackshaft 13 and the jackshaft 12 by two ball bearings respectively, driving shaft 11 is bearing on the casing of transmission case bottom by two ball bearings 17, two ends are fixing with bearing cap 18, stretch out outside the bearing cap 18 at driving shaft 11 two ends, with outside framework oil seal 16 sealings.Driving shaft 11 is a hollow body, and its endoporus is six (or four, eight) square hole, and gear 9 is fixed on the driving shaft 11 by flat key 19 and driving shaft 11 turns round together.In the square hole of driving shaft 11, plug corresponding square shaft 10(six sides or four, from all directions), square shaft 10 2 ends are loaded onto left and right two driving wheel assembly 4(buyable finished products), two end bolted then can be drawn farm machinery and be carried out operation; If driving wheel is pulled down, change rotary blade group 15, use bolt two ends fastening equally, just can carry out rotary tillage operation (rotary blade group buyable finished product).

Engine 3 of the present utility model is fixed on the very narrow frame 5 of lateral dimension, the same hand tractor of other parts.

An operation such as the utility model can enter between the less ridge of spacing and intertill, weeding, ridging, fertilising has realized the effect that replaces animal power, replaces manpower; Because the utility model volume is little, in light weight, can be used for carrying out various operations in the green house of vegetables simultaneously, also can be used for horticulture-working; The utility model is loaded onto the rotary blade group and is carried out the rotary tillage operation, and the spacing of left and right sides cutter group can be 5cm, can realize not having and balk, as load onto driving wheel and just can carry out above-mentioned various towage.

Fig. 1 is an outside schematic diagram of the present utility model.

Fig. 2 is a general assembly schematic diagram of the present utility model.

Fig. 3 is a general assembly end view of the present utility model.

Fig. 4 is that the utility model is loaded onto rotary blade group schematic diagram.

Fig. 5 is a square axle structure schematic diagram of the present utility model.

Fig. 6 is a square axle structure end view of the present utility model.

When the utility model used as rotovator, the rotary blade assembling was joined schematic diagram and is seen accompanying drawing 4, and a square shaft (size is by the wide decision of rotary blade group) is passed driving shaft, and 2 rotary blade groups (purchasing finished product) are respectively adorned in both sides, and the two ends bolted of axle gets final product work.At first start diesel engine, divide clutch then, gear lever is placed the gear of needs, harder as soil property, then can put and pay gear lever in low gear, main shift lever places 2 or 3 to block, comparatively soft as soil property, then can place high gear with paying gear lever, main shift lever places 1 or 2 retainings (being high 1 retaining or high 2 retainings), engaging clutch can begin the rotary tillage operation, and controlling throttle large and small is the rotating speed of controlled rotary blade.

Claims
