Abstract
The utility model relates to a hand tractor, particularly a three-wheel hand tractor for a combined walking mechanism which can realize a double-wheel driving mode and a three-wheel driving mode. The utility model has the characteristics that the lower part of the front end of a machine frame (7) is provided with an auxiliary walking wheel shaft (9) of which the middle is provided with an auxiliary walking wheel (8); both ends of the auxiliary walking wheel (9) are fixed on the machine frame (7) through bearing seats (10), and the extended part of one end of the auxiliary walking wheel (9) is provided with a chainwheel (11); an output shaft (4) on the same side as the chainwheel (11) is provided with a chainwheel (12); the chainwheels (11), (12) realize transmission through a chain (13); the tail part of the machine frame (7) is provided with a second hanging connection opening (14). The utility model is capable of realizing the conversion of double-wheel walking and three-wheel walking, has the functions of traction and driving and improves the ability of adapting complicated landforms and carrying out farmland cultivation.
Description
Technical field
The utility model relates to a kind of walker tractor, more specifically to a kind of three wheeled walker tractors that can realize the combination traveling gear of two-wheel, two kinds of type of drive of three-wheel.
Background technology
What existing walker tractor adopted is two-wheel driven traveling mechanism, though this mode can satisfy haul, sowing, hang several work requirements such as cultivated, but exist not enough when being used for the farmland cultivation operation: first, because the stability factor of fore-and-aft direction, articulating of ploughshare can only be selected hard connecting mode, then cause the walking of complete machine also can only straight line to be walked, dumb, in plot in irregular shape and two ends, edge of a field place plough unclean, occur balking.The second, because the wheelspan restriction, a tire is walked at uncultivated land during ploughing, and another tire is walked in the ditch dug with a plow of ploughing, causes fuselage to tilt, if grading operation is all right, and when landform itself has the gradient, then is difficult to adapt to the horizontal wall inscription operation.The 3rd, the tire of walking rolls seriously raw soil layer in the ditch dug with a plow, makes the soil layer below the mellow soil layer become more and more harder in the course of time, does not meet the requirement of dark pine, and what be unfavorable for ploughing retains and conserve soil moisture and plant growth.
The utility model content
The purpose of this utility model provides a kind of front lower place on existing walker tractor chassis and installs an arbitrarily secondary row travelling wheel of dismounting additional, and any end that will wheel shaft is connected with cooresponding main road wheel wheel shaft by sprocket wheel, chain, thereby realize three wheel drive of walking line speed unanimity, and can carry out three wheeled walker tractors of two-wheel walking or three-wheel walking conversion according to the operation needs.
The utility model comprises driving engine, power-transfer clutch, change speed gear box, main road wheel and secondary row travelling wheel, be characterized in: the front end bottom in frame is provided with auxiliary live axle, the secondary row travelling wheel is equipped with in centre at auxiliary live axle, the two ends of auxiliary live axle are fixed on the frame by bearing seat, the one end stretches out the place and is provided with sprocket wheel, and also is provided with sprocket wheel on the output shaft of sprocket wheel homonymy, passes through chain, make two sprocket wheels realize transmissions, be provided with second at the afterbody of frame and articulate mouth.
The utility model can be realized the conversion that two-wheel walking and three-wheel are walked; When being engaged in cultivation operation, can select the three-wheel driven traveling, not only strengthen towability, and can realize that the activity of ploughshare articulates, make complete machine handy flexibly, reduce turn radius, improve along the adaptive capacity of curve walking; Can adjust the wheelspan of two main road wheels when plowing, make wheel not advance ditch dug with a plow, fuselage and ground keeping parallelism have increased the ability that adapts to the gradient, fully can be at 25 degree with interior slope work.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model three wheeled walker tractor structural representations;
Fig. 2 is the drive connection scheme drawing of the secondary row travelling wheel 8 in the utility model;
Fig. 3 is the main road wheel 5 Installation and Debugging scheme drawings in the utility model.
The specific embodiment
In Fig. 1,2,3: driving engine 1 and change speed gear box 3 all are fixed on the frame 7, and driving engine 1 outputting power passes to change speed gear box 3 through power-transfer clutch 2.Change speed gear box 3 left and right sides are drawn power take-off shaft 4 respectively, at the two ends of output shaft 4 main road wheel 5 is housed respectively, fixing between main road wheel 5 and the output shaft 4 by the flange 6 that can move axially and locate, its effect: be that the wheelspan of two main road wheels 5 can be adjusted as required.Change speed gear box 3 is installed in the rear end of frame 7, be provided with auxiliary live axle 9 in the front end bottom of frame 7, secondary row travelling wheel 8 is equipped with in centre at auxiliary live axle 9, the two ends of auxiliary live axle 9 are fixed on the frame 7 by bearing seat 10, and the radius of secondary row travelling wheel 8 is less than the radius of main road wheel 5.One end of auxiliary live axle 9 stretches out the place and is provided with sprocket wheel 11, is provided with sprocket wheel 12 with the output shaft 4 of sprocket wheel 11 homonymies, by chain 13, makes sprocket wheel 11,12 realize transmissions, its effect: to be to make secondary row travelling wheel 8 also be driven traveling.Be provided with second at the afterbody of frame 7 and articulate mouthfuls 14, its effect: be that the activity that is used for work implements such as ploughshare connects, articulate the acting point position and will be lower than output shaft 4, it is produced from gaining effect when work.The operation of complete machine control with have that walker tractor is the same to be undertaken by handrail 15 now.
Claims (2)
1, a kind of three wheeled walker tractors comprise driving engine (1), power-transfer clutch (2), change speed gear box (3), main road wheel (5) and secondary row travelling wheel (8), it is characterized in that:
A, be provided with auxiliary live axle (9) in the front end bottom of frame (7), secondary row travelling wheel (8) is equipped with in centre at auxiliary live axle (9), the two ends of auxiliary live axle (9) are fixed on the frame (7) by bearing seat (10), the one end stretches out the place and is provided with sprocket wheel (11), be provided with sprocket wheel (12) with the output shaft (4) of sprocket wheel (11) homonymy, by chain (13), make sprocket wheel (11), (12) realize transmission;
B, be provided with second at the afterbody of frame (7) and articulate mouthful (14).
2, according to claim 1 three wheeled walker tractors is characterized in that: the radius of secondary row travelling wheel (8) is less than the radius of main road wheel (5).
