Embodiment

[0039] A pneumatic expandable combination precision seeder, such as figure 1 As shown, it includes seed distribution system, seed precision sowing system, air pressure system and feedback system.

[0040] The seed distribution system comprises a seed box 12, a first-level seed separator 13, a first-level seed guide tube 14, a second-level seed separator 15 and a second-level seed guide tube 17, and the first-level seed separator 13 is arranged at the outlet of the seed box 12. The seed outlet of the first-level seed separator 13 is connected with at least one first-level seed introduction pipe 14 simultaneously, and the outlet of the first-level seed introduction pipe 14 is connected to the seed inlet of the second-level seed separator 15 respectively, and the second-level seed separator 15 The seed outlet is connected to at least one secondary seed guide pipe 17 at the same time, and the seed distribution system performs secondary distribution to the seeds in the seed box 12;...

Embodiment 2

[0050] Such as figure 2 As shown, the difference from Embodiment 1 is that the pneumatic expandable combined precision seeder is a single group expansion structure, that is, the seed outlet of the first-stage seed separator 13 is connected to a first-stage seed guide pipe 14, and the first-stage guide The outlet of the seed pipe 14 is connected to the seed inlet of a secondary seed separator 15, and the seed outlet of the secondary seed separator 15 is connected to five secondary seed introduction pipes 17 at the same time.

Embodiment 3

[0052] Such as image 3 As shown, the difference from Embodiment 1 is that the pneumatic expandable combined precision seeder has five sets of expansion structures, that is, the seed outlet of the first-level seed separator 13 is connected to five first-level seed guide pipes 14, and the first-level guide The outlet of the seed pipe 14 is connected to the seed inlets of five secondary seed separators 15 at the same time, and the seed outlet of the secondary seed separator 15 is connected to five secondary seed introduction pipes 17 at the same time.

Abstract

The invention relates to a pneumatic expandable combined precision seeder, which comprises a seed shunting system, a seed precise seeding system, a pneumatic system and a feedback system. Compared with the prior art, the pneumatic expandable combined precision seeder has the advantages that seeds are subjected to twice shunting, the pneumatic system is used for blowing and pressuring the seed shunting system, and an air suction principle is adopted in the seed precise seeding system, so that the precise seeding speed can be increased, the stability is high, and the seed leakage rate and re-seeding rate are low. Moreover, the precision seeder can be combined by expanding, so that the size of the seeder can be adjusted in order to adapt to seeding in plots of different scales. The feedback system can be used for detecting and analyzing the air pressure in the precise seeding system through a sensor, so that the air pressure at each place is adjusted automatically, and the efficiency and stability of precision seeding are ensured. The pneumatic expandable combined precision seeder has good precise seeding effects on various crop seeds, single-seed and single-hole seeding can be realized, and high seeding efficiency is achieved. Moreover, the size of the seeder can be adjusted specific to the sizes of different plots, so that the precision seeder is high in adaptability and is suitable for various land cultivated occasions.

Description

technical field [0001] The invention relates to a seeder, in particular to a pneumatic expandable combined precision seeder, which belongs to the field of agricultural planting and seeding. Background technique [0002] At present, the seeders used in large quantities in my country can be divided into two categories: (1) one is ordinary seeders, hole seeders and other types of seeders, which cannot precisely sow crop seeds, resulting in a large number of expensive Seeds are wasted, and it is greatly detrimental to the growth of later crops. (2) Ordinary precision seeder, this type of seeder saves seeds relatively, but the efficiency is low, and the sowing is uneven, and it cannot be carried out for fields of different sizes. Contents of the invention [0003] The present invention aims to overcome the deficiencies of existing planters such as poor precision seeding performance, high seed waste, low efficiency, and non-adjustable scale, etc., and provides a pneumatic expand...
