Embodiment 1

[0041] The steps for plot seeding are as follows:

[0042] 1) Drive the tractor, transmit power through the power input shaft 3 to make the seeder enter the normal working state, and drive the vacuum blower 16 and the air pump 1 to work.

[0043] 2) Start the solenoid valve control switch to make the vacuum blower 16 and the seed meter 26 form a vacuum under the connection of the three-way body 22 and the air guide pipe 15 to provide the seed meter 26 with suction power.

[0044] 3) The seed metering device 26 moves the seeds adsorbed on the forced seed metering disc 31 under the drive of the seed metering disc drive motor 19, and discharges them into the ditch as the forced seed metering disc 31 rotates.

[0045] 4) When seeding, the encoder 11 fixed on the ground wheel collects the rotation speed of the ground wheel 10, converts the data through the internal converter and transmits it to the seeding disc drive motor 19 to control the seeding speed, so that the seeder can com...

Embodiment 2

[0047] 1) The steps of community clearing are as follows:

[0048] 2) After the sowing of the plot is finished, the tractor stops moving forward but the power input shaft 3 still rotates. This rotation still provides power to vacuum blower 16, makes it produce vacuum degree. The switching device 71 is switched to the clearing direction, and the waste seed recovery chamber 23 is connected with the vacuum blower 26; the vacuum degree of the waste seed recovery chamber 23 is transferred to the seed storage housing 7 through the seed clearing pipe 21; Under the action, be sucked back to waste seed recovery chamber 23.

Abstract

The invention relates to an automatic control plot seeding machine which comprises a rack, a transmission system, a switching device, seed discharge devices, a waste seed recovery device, a furrow opener, land wheels, a vacuum fan and an air pump. The machine adopts an air suction seed discharge technology; seeds are absorbed on seed discharge plates and uniformly distributed along seed dischargeguide groove holes one by one; the seed discharge plates rotate to drive the seeds to rotate out of the seed discharge devices; precise single seed sowing is achieved; a utilization ratio of the seedsis increased; the waste is avoided; encoders fixed on the land wheels acquire rotating speeds of the land wheels and convert and transmit data to a seed discharge device driving motor through an internal converter; a rotating speed of the forced seed discharge plate is controlled by adjusting a rotating speed of the seed discharge device driving motor; a seeding plant distance is adjusted; and aseeding row distance is adjusted by adjusting distances between the two seed discharge devices and between the two land wheels. Seed discharge and seed clearing can be achieved by the switching device, and the purpose of quick seed clearing and no seed damage is achieved.

Description

technical field [0001] The invention relates to an automatic control seeder for a plot. Background technique [0002] Plot sowing is an important and basic link in agricultural breeding, and the quality of sowing directly affects the quality of crop breeding. The traditional plot planting machinery is inconvenient to adjust the plant spacing and row spacing, the cleaning of seeds is complicated, and it is easy to mix seeds. In order to solve this problem, the plot seeder we designed adopts air suction precision seeding technology. When the seeder is working, the negative pressure is generated by the vacuum fan, which is transmitted to the seed meter of the seed metering unit. The seed disc absorbs the seeds under the negative pressure of the seed meter, and discharges the seeds when it rotates driven by the drive motor. When the seeds turn out of the metering device, they no longer bear the positive pressure and fall into the ditch by gravity. The community seeder is diff...
