Abstract
The utility model discloses a light four-wheel driving tractor for paddy fields for agricultural production. A box type structure composed of a plurality of triangles is used in a machine frame, an engine and a gearbox are arranged in the machine frame, and an output shaft of the gearbox drives a middle differential mechanism through a chain. One path of the middle differential mechanism drives a rear differential mechanism through the chain, the rear differential mechanism drives a rear wheel to rotate through the chain, and the other path drives a front differential mechanism through the chain. The front differential mechanism drives a front wheel to rotate through ring type universal joint half shafts at both sides, and each ring type universal joint half shaft is composed of a semicircular ring joint, a rubber outer sleeve and filled powder. The utility model solves the problems that the front wheel not only drives but also turns and floats up and down, the four-wheel drive is achieved, and the self weight of a tractor body is lighter.
Description
The utility model relates to a kind of, is used for agricultural production, and light body four-wheel drive tractor is specially adapted to the every operation in paddy field.
In grain-production, paddy rice is main cereal crops, because of the multinomial farming of Rice Production, all is that the farm work of water is being arranged, therefore existing four-wheeled tractor is big because of weight, operation in the paddy field, it is darker to sink, and two wheel drive are easily skidded, it is bigger to add upper volume again, operation inconvenience in rice furrow is given the operation of paddy rice production mechanization, has increased difficulty.
The purpose of this utility model provides a kind of, and power is bigger, and volume is less, and weight is lighter, and cost is lower, and the trac. that is suitable for paddy-field-working of four wheel drive can supporting various work tools, carry out various paddy-field-workings, equally also can use in dry land.
Content of the present utility model is: frame is made rectangular box-shaped, left and right two side faces adopts triangular structure, driving engine, change speed gear box are placed in one, the output shaft of change speed gear box, drive middle diff rotation with chain, middle diff one tunnel diff after chain drives, back diff is defeated rotation after chain drives, the ring type propeller-shaft rotation of another road below chain drives front-axle beam, the ring type propeller-shaft is diff before chain drives, and the ring type articulated shaft of preceding diff two sides drives the front-wheel rotation.
The ring type universal-joint of this machine of being loaded on is made up of half dollar link, rubber sleeve and powder filler.
Advantage of the present utility model: 1, the design of the cabinet rack of triangular structure and ring type universal-joint alleviates deadweight 1/3rd than trac. of the same type.2, four wheel drive has improved tractive property.3, the ring type universal-joint has solved, and front-wheel should be driven, and turns to again, also wants upper and lower unsteady problem, and makes very simple.4, the ring type universal-joint also can need the mechanically use of wide-angle transferring power at other.

Below in conjunction with description of drawings the utility model embodiment, the frame (1) of light body four wheel drive paddy field tractor (hereinafter to be referred as paddy field tractor) is made rectangular box-shaped with angle steel, a left side, right two side faces connects into triangle ADE with angle steel, ABE, BEF and BCF, driving engine (2) change speed gear box (9) and driving device are housed in the box-shaped rack (1), bearing circle (11) is housed above the front-axle beam of paddy field tractor (37), the belt pulley (3) of driving engine (2) is through belt, belt pulley (38) on the power input shaft (6) of drive change speed gear box (9), the sprocket wheel (8) on the power take-off shaft (4) of change speed gear box (9) be sprocket wheel (23) rotation on the diff (5) in the middle of chain drives.Power take-off shaft (4) is again the load-bearing axle simultaneously, and the empty cover of two road wheels (13) in the above.The semiaxis (25) of middle diff (5) two sides is being fixed sprocket wheel (22) and (24) respectively, sprocket wheel (24) is the rotation of the sprocket wheel (34) on the diff (35) after chain drives, on the semiaxis (30) of back diff (35) two sides, fixing sprocket wheel (31) respectively, sprocket wheel (31) is the disjunctor sprocket wheel (33) on chain drive trailing wheel (13) respectively, makes trailing wheel (13) rotation.Sprocket wheel (21) on the ring type propeller-shaft (16) of opposite side sprocket wheel (22) on the middle diff (5) below chain drives square tube type front-axle beam (37), make ring type propeller-shaft (16) rotation, the sprocket wheel (19) of the diff (10) before chain drives of the other end sprocket wheel (20) on the ring type propeller-shaft (16), make preceding diff (10) rotation, the ring type articulated shaft (15) of preceding diff (10) two sides, pass the hollow shaft (47) on the connecting shaft (44), the front-wheel (14) that is enclosed within on the hollow shaft (47) with sky is connected, and drives front-wheel (14) rotation.
Preceding diff (10) is loaded on below the propons 9.
Propons (9) is connected with pin hole (26) on the square tube type front-axle beam (37) with pivot pin (27).
The vertical shaft (46) of connecting shaft (44) is loaded on the vertical shaft sleeve (45) on the propons (9).
Ring type propeller-shaft (16) is equipped with an end of sprocket wheel (21), be installed in below front-axle beam (37) siamesed axle casing seat (40), the end that sprocket wheel (20) is housed be installed in propons (9) siamesed axle casing seat (41) on, the position, the left and right sides of ring type universal-joint (16) will be under front-axle beam (37), and high and low position will be on the line of centers of the pin hole (26) on the front-axle beam (37).
The half dollar ring (52) of ring type universal-joint is welded on the circular flat plate (51), semicircular ring (53) is enclosed within on the semicircular ring (52), and be welded on the surface plate (54), semicircular ring (55) is welded on the another side of circular flat plate (54), semicircular ring (56) is enclosed within on the half dollar ring (55), and be welded on the circular flat plate (57), each joins the surface plate of semicircle link (51) and (57) with axle, and put (not drawing among the figure) with the rubber sleeve of good springiness, and in cover, fill powder filler, doing powder filler with graphite powder or french talc all can, as the lubricant between annulus joint and the annulus joint, powder filler and rubber sleeve also play the irregular movement that the annulus that prevents to be produced because of vibrations saves jointly simultaneously, fill powder filler after, the good seal rubber sleeve guarantees that powder filler can not release.
