[0025] The quantitative taking-out assembly comprises rotating roller one 12, arc-shaped material blocking plate 9, quantitative groove 13, rotating roller two 14, motor 15, receiving opening groove 17, threaded rod 11 and L-shaped mounting rod two 10. Two groups of L-shaped mounting rod two 10 are arranged at the middle positions of the bottoms of the two sides of storage bin 8. The bottom of the inner side of one group of L-shaped mounting rod two 10 is provided with motor 15. The output end of motor 15 is provided with rotating roller two 14. The top and bottom of the side, away from motor 15, of rotating roller two 14 are provided with receiving opening groove 17. The interiors of the two groups of receiving opening groove 17 are insertedly provided with quantitative groove 13 extending to the outside. The side, away from rotating roller two 14, of the two groups of quantitative groove 13 is commonly provided with rotating roller one 12. The middle position of the side, away from quantitative groove 13, of rotating roller one 12 is provided with threaded rod 11. Threaded rod 11 is screwed through to the outside of the other group of L-shaped mounting rod two 10. The top of the outside of rotating roller one 12 and rotating roller two 14 is sleeved with arc-shaped material blocking plate 9. The top of arc-shaped material blocking plate 9 is connected with the middle position of the bottom of storage bin 8. This facilitates the quantitative taking-out operation of seeds. Meanwhile, it is also convenient to adjust the space capacity of quantitative groove 13, so as to facilitate the seeding operation of different amounts of seeds and increase the flexibility and convenience of the later operation adjustment of the seeding machine.

[0026] The middle positions of the interiors of the bottoms of storage bin 8 are provided with discharge ports. The discharge ports are matched with quantitative groove 13 through arc-shaped material blocking plate 9. This facilitates the dropping and taking-out operation of seeds. The side, away from each other, of the outside of rotating roller one 12 and rotating roller two 14 is sleeved with fixed rotating shaft. The fixed rotating shaft is connected with the bottom of storage bin 8. This facilitates the rotating installation of rotating roller one 12 and rotating roller two 14. The inner bottom of the other group of L-shaped mounting rod two 10 is provided with internal thread hole. The internal thread hole is matched with threaded rod 11. This facilitates the rotating displacement operation of threaded rod 11. The top of the side, close to each other, of the two groups of fixed rods 3 is provided with limiting sleeve. The interior of the limiting sleeve is provided with limiting rod connected with storage bin 8 through fixed rod 3. This facilitates the limiting of the displacement of storage bin 8 and prevents it from rotating with adjusting screw rod 6, so as to improve the stability of the displacement.

[0027] Working principle: when in use, control mechanism 1 controls the displacement operation of driving mechanism 16, so as to realize the advancing, retreating or turning operation of the seeding machine. When the seeding operation of different distance furrows is needed, the rotating operation of internal thread sleeve 7 can be directly realized through servo motor 5. At this time, through the thread engagement operation of internal thread sleeve 7 and adjusting screw rod 6, the rotating of internal thread sleeve 7 can push adjusting screw rod 6 to drive storage bin 8 and the components above it to realize the operation away from control mechanism 1 and the components above it. In this way, it is convenient to realize the close of storage bin 8 and the components above it to the furrow, so as to directly seed in the later period without the need of realizing the close of the furrow through the turning adjustment of control mechanism 1 and the components above it. This improves the efficiency of the later seeding.

[0028] Meanwhile, the seeds can be placed in the storage bin 8 for storage, and then the rotation of the motor 15 can drive the rotation roller two 14, the quantitative groove 13 and the rotation roller one 12 to rotate simultaneously. When the quantitative groove 13 is positioned directly below the bottom of the storage bin 8, the seeds in the quantitative groove 13 can directly fall into the quantitative groove 13 to realize the quantitative feeding operation of the seeds. Then, the motor 15 can continuously drive the rotation of the rotation roller two 14, the quantitative groove 13 and the rotation roller one 12, so that the quantitative groove 13 with the seeds is positioned directly below the arc-shaped blocking plate 9, and then the seeds can be dropped and sowed. The design of the arc-shaped blocking plate 9 can block the rotation roller one 12, the quantitative groove 13 and the rotation roller two 14, so as to prevent the seeds from falling from other directions. When different seeds with different quantities need to be sowed, the operator can directly rotate the rotation roller one 12 to move in the L-shaped mounting rod two 10, and then drive the rotation roller one 12 and the quantitative groove 13 to move away from the rotation roller two 14. Then, the quantitative groove 13 can be pulled out of the receiving opening slot 17 to expand the capacity of the quantitative groove 13, so as to realize the sowing operation of different seeds with different quantities, thereby increasing the quality of the sowing machine and the flexibility and practicality of the sowing operation.

[0029] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range of ordinary skilled in the art without departing from the purpose of the utility model.
