Abstract

The utility model provides a three-wheel chassis used for growing of crops, fertilization and protection of crops in both paddy fields and dry farms. The utility model consists of a driving wheel, a transmission case, a mounting bracket, an engine, a directional operating handlebar, gimbals, a frame, a chair, a lift link, a curb chain, a top rest, a rear-wheel spindle and rear wheels and so on. The fore wheel of the utility model is a single driving wheel, and is a steel framework non-inflated rubber impeller; the rear wheels of the utility model are freely turning wheels, and are steel framework deep pattern non-inflated rubber wheels. The top rest is articulated on the rear-wheel spindle, and plays a role in flatting and earth backing during planting. No accumulated soil or water inflow occurs in the process; it is not required to replace the wheels when the utility model gets into or out of paddy fields; the utility model is usable; and the utility model is both applicable for paddy fields and dry farms.

Description

Water, the general three-wheel of dry land chassis

Technical field

The utility model belongs to agricultural machinery, especially is fit to match with water, dry crop sower, transplanter, fog machine and fertilizer distributor.

Technical background

At present, dry land sowing, transplanting, plant protection and fertilising operation are with corresponding machinery and general dynamic---tractor matches, this supporting form is extremely incompatible to the corresponding operation in paddy field, and reason is the specification requirement that aspects such as anti-depression, anti-slip, mud-preventing and anti-water burst must be satisfied in the machines working in paddy field chassis; Be used for paddy field sowing, transplant, the machinery of fertilising, its chassis all is special-purpose, rice transplanter chassis special, the unit head of joining deck of boat form as unit head joined the sower chassis special and the four wheel drive rice transplanter chassis special of deck of boat form.Though, unit head is joined simple in structure, the low price of chassis special of deck of boat form, but it only is used for sowing, transplants, and the two is not general, and the fertilising operation must and be transplanted operation and finish with sowing, can't finish plantation fertilising and plant protection work afterwards, its maximum shortcoming is that heap soil or fertilizer over and around the roots mud, water burst problem are serious, and the reinforcing bar impeller need be changed in upper and lower paddy field, wastes time and energy.As the good J-2BD series of 2Z series rice transplanter and Shanghai rice seeder etc., employing be this type of chassis.Four wheel drive rice transplanter chassis special is all-hydraulic, four wheel drive structure, stop up mud, water burst problem though have or not, and wheel need not be changed in upper and lower paddy field, still, its complex structure, hydraulic system breaks down and is difficult to diagnosis, only be used for paddy-field-working, and cost is very high, as RR6 type rice transplanter of Japanese Kubo field SPU-68 type rice transplanter, foreign horse and the P600 type rice transplanter of Korea S Japan etc., these machineries have all adopted four-wheel full hydraulic drive chassis.Still this type of universal chassis that is not suitable at present paddy field and dry land comes out.

Technology contents

The utility model is intended to solve the versatility problem on the light-duty chassis of paddy field and dry crop plantation, fertilising and equipment for plant protection, to improve the availability of agricultural machinery, reduces investment.The utility model paddy field and dry land are general, can satisfy dry land operation needs, can solve again the heap soil or fertilizer over and around the roots mud, water burst problem of paddy-field-working and up and down the paddy field change the wheel subproblem, also can satisfy the paddy-field-working requirement at aspects such as anti-slip, depressions.

The utility model is a kind of water by front-wheel drive, the general three-wheel of dry land chassis.This chassis mainly by driving wheel 1, gearbox 2, mounting bracket 3, engine 4, direction operator 5, universal joint 6, frame 7, seat 8, lifting arm 9, chain 10, upper slide rest 11, hind axle 12 and trailing wheel 13 etc. form, engine 4 is installed on the gearbox by mounting bracket 3; Driving wheel 1 is connected on the walking output shaft of gearbox 2 bottoms, and driving wheel has only one; The direction operator is 5 tops that are connected in gearbox 2; Vertically hinged between frame 7 and the gearbox 2; Seat 8 is installed in the back upper place of frame; Trailing wheel 13 is two free moving runners, is installed in the back lower place of frame by hind axle 12 and bearing spider, and trailing wheel has two; Lifting arm 9 is laterally hinged with frame 7 edge in horizontal plane, and upper slide rest 11 is hinged on the hind axle, and hangs on the rear end of lifting arm 9 by chain 10; Universal joint 6 is connected on the operation power output shaft of gearbox, in order to drive equipments such as transplanting, sowing, fertilising and plant protection.

The utility model is the general three-wheel chassis of water, dry land, no hydraulic system, and the no deck of boat, simple in structure, be convenient to safeguard, cheap.The utility model adopts the single-wheel front wheel driving, and driving wheel 1 is a reinforcing bar on-inflatable rubber impeller, and its blade is more roomy; Trailing wheel 13 is two free moving runners, is not inflating rubber wheel of the dark decorative pattern of reinforcing bar.Because this wheel can satisfy the requirement of paddy-field-working anti-slip, anti-depression, mud-preventing and anti-water burst aspect, that can satisfy the dry land operation again and requirements such as the anti-slip hard pavement walking, buffering, therefore, wheel need not changed in upper and lower paddy field, easy to use, paddy field, dry land are general.In addition, the utility model also is hinged with upper slide rest 11 on hind axle 12, transplant, during the straight line operation of sowing, upper slide rest 11 plays level land or the effect of volt soil, turn and during other operation, by lifting arm 9 and chain 10 with upper slide rest 11 pull-ups.

Now be described further in conjunction with the accompanying drawings:

Fig. 1 is the utility model overall construction drawing.

1 is driving wheel, and 2 is gearbox, and 3 is mounting bracket, and 4 is engine, and 6 is universal joint, and 7 is frame, and 12 is hind axle, and 13 is trailing wheel.Engine 4 is contained on the gearbox 2 by mounting bracket 3, and power is transferred to gearbox 2 by engine 4 by band, power is provided for other equipment by universal joint 6 on the one hand, on the other hand, by the walking output shaft driving wheel 1 is rotated, and draws moving of complete machine; Trailing wheel 13 is free moving runner, is installed on the frame 7 by hind axle 12 and bearing spider; Gearbox 2 is hinged at vertical direction with frame 7, guarantees that there is little radius of turn on the chassis.

During work, control clutches, walking speed change and work speed change by gearbox 2, and realize the operation of different spacing in the rows, upper slide rest 11 only plays the level land or lies prostrate the soil effect when the straight line operation of transplanting, sowing, and at this moment, upper slide rest is put down; When turning or other operation, step on lifting arm 9, upper slide rest 11 is sling by chain 10 by the operator.

The utility model is the single-wheel front wheel driving, and driving wheel 1 is a reinforcing bar on-inflatable rubber impeller; Trailing wheel 13 is two free moving runners, is not inflating rubber wheel of the dark decorative pattern of reinforcing bar.This wheel can satisfy the requirement of paddy-field-working anti-slip, anti-depression, mud-preventing and anti-water burst aspect, that can satisfy the dry land operation again and requirements such as the anti-slip hard pavement walking, buffering, therefore, wheel need not changed in upper and lower paddy field, easy to use, paddy field, dry land are general.
