Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1 to 5, the invention provides a yam sowing device, which comprises a bracket 5 and a material barrel 1 movably arranged on the bracket 5, wherein a movable push rod 2 is arranged in the material barrel 1, a material rod 3 is fixed on the push rod 2, the push rod 2 and the material rod 3 are both in cylindrical structures, and the material rod 3 and the push rod 2 are coaxial;

the end part, far away from the push rod 2, of the material rod 3 is fixedly provided with a plug 4, the plug 4 is tangent to the inner wall of the charging barrel 1, and the outer diameter of the material rod 3 is smaller than the inner diameter of the charging barrel 1.

Further, the plug 4 is of an ellipsoid structure, the length of a long axis of the plug 4 is the same as the inner diameter of the charging barrel 1, and the outer diameter of the material rod 3 is smaller than the length of the long axis of the plug 4 and larger than the length of a short axis of the plug 4. On the one hand, end cap 4 adopts the structure of the ellipsoid, and when figure 1 state, end cap 4 can be tangent with the inner wall of feed cylinder 1, and then avoids the seed to drop, and on the other hand, when end cap 4 was in the state of figure 5, utilized the structure of its ellipsoid, when push rod 2 and material pole 3 produced axial deviation in feed cylinder 1, utilized its characteristics that have the major axis for the soil hole can obtain the extension, and then guarantees that the seed falls smoothly in the soil hole.

Further, two limiting columns 11 are symmetrically fixed on the inner wall of the charging barrel 1, T-shaped limiting grooves 111 are formed in the limiting columns 11, two telescopic rods 21 in one-to-one correspondence with the limiting columns 11 are fixed on the material rod 3, and T-shaped bosses sliding in the T-shaped limiting grooves 111 are fixed at the telescopic ends of the telescopic rods 21.

Further, a linear bearing 51 is arranged at the joint of the support 5 and the charging barrel 1, and a plurality of supporting legs 52 which are uniformly distributed are further arranged on the support 5.

Furthermore, two support rods 12 are symmetrically arranged on the charging barrel 1, the push rod 2 is far away from a stop block fixed at the end part of the material rod 3, a support rod 13 is arranged at the end part of the charging barrel 1 close to the stop block, and a spring 6 nested on the push rod 2 is arranged between the support rod 13 and the stop block.

During the use, pour into feed cylinder 1 with partial seed in, end cap 4 is located inside feed cylinder 1 under the effect of spring 6, and then avoid the seed to drop, when needs sow, operating personnel arranges the device in seeding position department, press vaulting pole 12, feed cylinder 1 moves down (shown by the arrow in figure 5) for support 5, and then enter the soil horizon, simultaneously because the existence of spacing post 11, make end cap 4 can't shift up for feed cylinder 1, consequently can extrude a soil hole on the soil horizon, then pressing the dog, make end cap 4 move down, when end cap 4 is located the state in figure 5, the seed can be followed feed cylinder 1 and dropped this moment, rock push rod 2 about simultaneously, usable end cap 4 is with the soil hole extension, and then guarantee that the seed can fall into, improve planting effect. In addition, it should be noted that, during actual manufacturing, the distance that the plug 4 moves downwards needs to be adaptively set according to the size of the yam seeds, that is, in the state shown in fig. 5, the gap between the plug 4 and the barrel 1 should not be too large so as to prevent too many seeds from falling.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
