Description
Technical field
The present invention relates to a kind of walking rice transplanter, be specifically related to a kind of rear-mounted direction adjusting mechanism of legged rice transplanter, can be used for the adjustment of legged rice transplanter direction when unmanned.
Background technology
In China Rice Cropping zone, hilly and mountainous land occupies larger proportion.Legged rice transplanter is suitable for the large-scale planting in hilly and mountainous land zone, has widely market prospects.During the work of rice transplanter, generally advance along straight line or predetermined path, until edge of a field J-turn.The support of three kickboards of two road wheels and back about legged rice transplanter relies on guarantees steadily and not understanding front and back and tilting of fuselage; The transmission of power to two of an engine road wheel is realized moving forward and backward.Because the paddy field circumstance complication, the frictional resistance that left and right sides road wheel is subject to is different, and rice transplanter tends to off-straight or predetermined path, needs real-time its direction of adjustment to travel along straight line or predetermined path with assurance.So need artificial hand steered advancing during legged rice transplanter work, so that the power of two handrails about constantly adjustment is applied to guarantees that rice transplanter can travel along straight line or predetermined path.Yet the labour intensity of hand steered operation is large, and work under bad environment is in the urgent need to the unmanned operation of legged rice transplanter.The unmanned rice transplanter of having developed at present all is the transformations to riding-type rice planter, there is not yet at legged rice transplanter and uses unmanned technology and corresponding direction adjusting mechanism.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned background technology, a kind of rear direction-regulation device of walking ice transplanter is provided, that this mechanism should have is simple in structure, implement easily, direction characteristics easy to adjust.
The objective of the invention is to be achieved through the following technical solutions:
Rear direction-regulation device of walking ice transplanter is characterized in that: described direction adjustment device comprises the axle sleeve that vertically is fixed on the rice transplanter After-Body, insert in the axle sleeve and the rotating shaft, the wheel carrier that is fixed on the rotating shaft lower end that match with it, be installed in directive wheel on the wheel carrier, laterally be fixed in the rotating shaft and be positioned at the moving block of axle sleeve bottom, moving block applied the oil cylinder of rotating torque; The cylinder body of described oil cylinder is hinged on the rice transplanter body, and the piston rod of oil cylinder and described moving block are hinged, and the hinge axes of two pin joints is all perpendicular to ground.
The top of described axle sleeve is provided with a tight fixed ring that prevents the downward slippage of rotating shaft.
Hinged by contiguous block between the piston rod of described oil cylinder and the moving block, this contiguous block is L shaped, and a limit of contiguous block is positioned at the top of piston rod, and another limit and described contiguous block are hinged.
Operation principle of the present invention is: as shown in Figure 4, when rice transplanter is turned left when departing from predefined paths, the piston rod that external signal triggers oil cylinder shrinks, the pulling moving block rotates counterclockwise (direction shown in Figure 4), thereby pulling rotating shaft rotates counterclockwise, directive wheel is offset an angle beta to the right, and rice transplanter can be subject to clockwise moment of face M, thus make rice transplanter turn right to; As shown in Figure 5, when rice transplanter is turned right when departing from predefined paths, external signal triggers the piston rod elongation of oil cylinder, promote moving block and clockwise rotate (direction shown in Figure 4), thereby pulling rotating shaft clockwise rotates, directive wheel is offset an angle beta left, and rice transplanter can be subject to counterclockwise moment of face M, thus make rice transplanter turn right to.
The invention has the beneficial effects as follows: the present invention utilizes the flexible moving block that makes of oil cylinder to rotate, thereby directive wheel is turned an angle, realize the direction adjustment of walk-behind type paddy-field work machine, simple in structure, implement easily, and production cost is also cheaper, in addition, it is shorter that the present invention realizes that the walk-behind type paddy-field work machine direction is regulated the required time, and the precision that direction is regulated is also higher.

Embodiment
Below in conjunction with Figure of description, the invention will be further described.
As shown in Figure 1, rear direction-regulation device of walking ice transplanter of the present invention comprises directive wheel 8, rotating shaft 6 and the axle sleeve 9, oil cylinder 3, moving block 5, contiguous block 4, the tight fixed ring 10 that are installed on the wheel carrier 7; Described axle sleeve vertically is fixed on the installing plate 2 at rear portion of rice transplanter body 1, and rotating shaft is rotatably positioned in this axle sleeve, and the bottom of rotating shaft is provided with wheel carrier and is installed in directive wheel on the wheel carrier; The top of described axle sleeve is installed with tight fixed ring in case the spline Axisal movement moves, and the bottom of axle sleeve is provided with and prevents the make progress moving block of slippage of rotating shaft, and this moving block laterally is fixed in the rotating shaft; Simultaneously, this moving block also can be pulled rotating shaft and rotate: moving block is away from an end of rotating shaft and the piston rod hinged (hinge axes of pin joint is perpendicular to ground) of oil cylinder, and the cylinder body of this oil cylinder is hinged on (hinge axes of pin joint vertically) on the rice transplanter body.When piston rod elongation or contraction, all can drive moving block and in certain angular range, swing back and forth, rotate thereby drive rotating shaft; As shown in Figure 2, this angular range represents with α; Figure 3 shows that the maximum angle that deflecting plate turns left, i.e. α/2, the maximum angle that deflecting plate turns right also is α/2.
Hinged by contiguous block between the piston rod of described oil cylinder and the moving block, this contiguous block is L shaped, and a limit of contiguous block is positioned at the top of piston rod, and another limit and described contiguous block are hinged.Piston rod is direct and moving block is hinged, specifically determines according to actual conditions.
Fig. 3, Fig. 4, Fig. 5 cathetus arrow direction are the anterior direction of rice transplanter.Dotted line is depicted as the predefined paths of rice transplanter motion among Fig. 3, Fig. 4, Fig. 5.
Described oil cylinder, directive wheel and wheel carrier buyable obtain.
