The device comprises a power shaft 1, a cam 2, a bracket 3, a seed discharging pipe 4, a seed discharging rod 5, a spring 6, a base 7, an upper hollow conical box 8, a lower hollow conical box 9, a seed loading port 10, a seed charger 11, a seed charging hole 12, a seed discharging hole 13 and an inclined sliding chute 14.
Detailed Description
The specific structure and operation of the embodiments of the present invention are described below with reference to the accompanying drawings:
as shown in fig. 1-6, the up-and-down reciprocating seed sowing device is generally arranged on a frame of a seeder through a bracket 3 and comprises a driving mechanism which is mainly composed of a power shaft 1, a cam 2 and a base 7; the seeding mechanism mainly comprises a seeding pipe 4, a seeding rod 5, a spring 6, a seed charger 11, a seeding hole 13, an inclined chute 14 and the like; mainly comprises three parts of a seed box, namely an upper hollow conical box 8, a lower hollow conical box 9 and the like.
The seed charger 11 and the spring 6 are sequentially sleeved at the upper end of the seed discharging rod 5 from top to bottom, the lower end of the seed discharging rod 5 is welded on the base 7, the power of the power shaft 1 is provided by the land wheel of the seeder, and the power shaft drives the cam 2 to rotate so as to drive the base 7 to reciprocate up and down. The upper end surface of the seed discharging rod 5 is inclined (the inclination angle is 45-55 degrees), the diameter of the upper end surface is slightly smaller than the aperture of the seed discharging hole 13 of the upper hollow conical box 8 by 2-3mm, so that the seed discharging rod 5 can freely move up and down in the seed discharging hole 13, the outer diameter of the seed charger 11 is about 5mm larger than the aperture of the seed discharging hole 13 of the upper hollow conical box 8, when the upper end surface of the seed charger 11 upwards moves to be flush with the lower end surface of the seed discharging hole 13, the lower end surface of the seed discharging hole 13 can limit the seed charger 11 to continuously move up, the seed charging device 11 is limited to continuously move up, the seed discharging rod 5 is pushed by the cam 2 to continuously move up, and the spring 6 is compressed. The upper port of the seed discharging pipe 4 is lower than the seed discharging hole 13 and is positioned at the position which is 50mm below the side of the seed discharging hole 13, and the seed discharging pipe and the seed discharging hole are connected through an inclined sliding chute 14, so that seeds pushed out by the seed discharging rod 5 along the seed discharging hole 13 can smoothly enter the seed discharging pipe 4, and seed discharging is completed.
During operation, the ground wheel of the seeder drives the power shaft 1 to rotate through the chain, so that the cam 2 is driven to rotate, and the seed sowing rod 5 is driven to reciprocate up and down while the cam 2 rotates. When the cam 2 is positioned at the near-repose angle, the seed sowing rod 5 is positioned at the lowest end, and at the moment, seeds in the seed box slide into the seed filling device 11 under the action of gravity and enter the seed filling hole 12 to finish seed filling. With the rotation of the cam 2, the seed metering rod 5 drives the seed charger 11 and the spring 6 to move upwards together, when the upper end surface of the seed charger 11 is flush with the lower end surface of the seed metering hole 13, the seed metering hole 13 limits the seed charger 11 to move upwards continuously, the seed metering rod 5 at the moment pushes the seeds to move upwards continuously along the seed metering hole 13, and the spring 6 is compressed. When the cam 2 rotates to a far angle of repose, the seed rod 5 reaches the highest point. The seed sowing rod 5 discharges seeds from the seed sowing hole 13 by utilizing the inclined plane at the upper end, and the seeds enter the seed sowing pipe 4 along the inclined chute 14 to finish seed sowing. When the cam 2 continues to rotate, the seed sowing rod 5 descends under the action of the spring 6 and the self gravity to perform the next seed charging and seed sowing process. The invention is suitable for the seeder of intertillage crops such as corn, soybean and the like.
Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
