Abstract
The invention discloses an elastic-sheet seedling-pushing type planting arm. A seedling needle is fixedly connected with the top of a shell, the lower side, extending out of the shell, of the seedling needle is provided with an inwards concave guide groove, and the shell is provided with a hole in the extending direction of the seedling needle. The planting arm is characterized in that a driving wheel, a middle wheel and a driven wheel are all connected with the shell through a revolute pair, the middle wheel is of a double-connection structure, one part of the middle wheel forms flexible piece transmission a with the driving wheel through a flexible piece, while the other part of the middle wheel forms flexible piece transmission b with the driven wheel through another flexible piece, one end of each elastic sheet is fixedly disposed on the flexible pieces while the other end of each elastic sheet is bent to be tightly pressed on the shell, and the elastic sheets pass through the gaps between the flexible pieces and the shell along with the flexible pieces. By virtue of the planting arm, the linear reciprocating type seedling pushing movement of a common rigid seedling pushing rod is changed to be the free returning and popping type seedling pushing movement of the elastic sheets dragged by the flexible piece transmission b, the vibration impact and noise of the planting arm are reduced, and thus the work of the planting arm is quieter and more smooth and steady.
Description
Technical field
The present invention relates to rice transplanter, the flexure strip that is specifically related to a kind of rice transplanter planetary gear train type transplanting mechanism pushes away seedling formula transplant arm.
Background technology
Pulling seedlings device in rice transplanter transplant arm is a kind of timing reciprocator, and its effect is that the blanket appearance seedling on rice seedling box of rice seedling transplanting machine is taken off to a fritter and implanted Tanaka's device.At present, planetary gear train of rice transplanting machine formula transplanting mechanism transplant arm version and the pulling seedlings device transmission principle thereof at home and abroad on market, sold are consistent, transplant arm is realized rice transplanting track with transplanting mechanism, pulling seedlings device in transplant arm is done the straight reciprocating motion with respect to transplant arm: by plane cam, shift fork, transplanting rod and spring complete seedling pushing action jointly, its version is simple, but owing to pushing away rice seedling distribution mechanism in implementing rice transplanting operation process, to carry out work with the frequency of 100～200 times per minute, what in this process, must overcome that spring is greater than 100N pushes away seedling acting force of the spring, certainly will cause like this consumes energy high, mechanical wear is fast, relative vibration is large, the disadvantages such as service life is short.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, flexure strip of the present invention pushes away seedling formula transplant arm, seedling pin (7) is fixedly connected on housing (1) top, seedling pin (7) stretches out the gathering sill that housing (1) downside is partly provided with indent, housing (1) stretches out direction at seedling pin (7) and is provided with an aperture (19), it is characterized in that driving wheel (2), breast wheel (8) and driven pulley (5) connect with revolute pair with housing (1) respectively, breast wheel (8) is duplex structure, its part forms flexible element transmission a with driving wheel (2) by flexible element (3), its another part and driven pulley (5) form flexible element transmission b by flexible element (4), one end of flexure strip (6) is fixed on flexible element (4), the other end is subject to curved being pressed on housing (1), with flexible element (4), run in the guide in the space between flexible element (4) one weeks and housing (1).
Described flexure strip (6) is while naturally upholding
or
etc. shape, cross section is "-" shape, and lower end is stiff end, by direction shown in figure (1), installs.
The upper fixing flexure strip (6) of described flexible element (4) can, for a plurality of, are " one " font and longitudinally uniformly-spaced arrange.
Described flexible element transmission a and flexible element transmission b can be all chain transmission or toothed belt transmission.
The width of the gathering sill on described seedling pin (7) is more than or equal to the width of flexure strip (6).
The upper aperture (19) of described housing (1) be positioned at the upper gathering sill of seedling pin (7) under, its orthographic projection is rectangle, width equals the width of gathering sill.
On described housing (1), be provided with square installing hole (9), installing hole (9) connects for described pulling seedlings device and transplant arm.
The available spring steel of described flexure strip (6) or other have larger flexible material and make.
As shown in Figure 3, allow shown in Fig. 2 in transplanting mechanism planet wheel spindle through the through hole (17) at wheel (2) center in transplant arm of the present invention, planetary gear square shaft end (11) inserts installing hole (9), formation profile connects, simultaneous wheels (2) axle head square face (18) inserts square opening (12) on transplanting mechanism housing, forming profile connects, another transplant arm of the present invention is installed in the same way to transplanting mechanism, is made planetary gear square shaft end (14) all form profile with installing hole (9) and wheel (2) axle head square face (18) with square opening (15) on transplanting mechanism housing and connect.
Operation principle of the present invention is as follows:
In Fig. 3, the housing of transplanting mechanism (10) moves in a circle around sun wheel shaft (13), drive two transplant arms to do composite plane motion, make seedling pin (7) realize the required track of rice transplanting, simultaneous wheels (2) is pressed direction shown in Fig. 1 and is rotated, by flexible element transmission a and flexible element transmission b, make flexible element (4) make diagram directional ring shape shuttling movement, thereby move with one end flexure strip fixed thereon (6), because the gap between flexible element (4) and housing (1) is less, so flexure strip (6) produces flexural deformation while being pulled into housing (1), the inwall that its free end presses housing (1) slides, when flexure strip (6), being taken out of aperture (19) locates moment distortion occurs freely to reply, process as shown in Figure 6, thereby the rice shoot (16) being clipped on seedling pin (7) is pushed in soil, flexure strip (6) is pulled into housing (1) with same attitude again afterwards, seedling pin (7) seedling taking from seedling dish, when rice shoot arrives precalculated position, flexure strip (6) is just taken out of aperture (19), there is freely to reply distortion in moment, thereby the rice shoot (16) being clipped on seedling pin (7) is pushed in soil.
Above-mentioned embodiment is used for the present invention that explains; rather than limit the invention; in the protection domain of spirit of the present invention and claim, all the present invention is taked to be equal to replace or technical scheme that equivalent transformation obtains, all fall into protection scope of the present invention.
