Mechanical sliding piece translational motion type precise sowing device with air channel seed selecting function

Abstract

The invention relates to a mechanical sliding piece translational motion type precise sowing device with an air channel seed selecting function. The precise sowing device comprises a seed selecting mechanism, a seed charging mechanism and a seed charging-discharging mechanism. The seed selecting mechanism comprises a seed cleaning part and a sorting part; a funnel of the seed cleaning part is installed on a seed cleaning rack, the bottom of the funnel is provided with a guide groove, a poking amount adjusting plate is installed in the guide groove, a fan is arranged below the poking amount adjusting plate, one end of a conveying pipe is connected with an air outlet of the fan, and the other end of the conveying pipe extends to a position above the sorting part; the sorting part comprises aplurality of stacked sorting boxes, and the bottommost sorting box is arranged above the seed charging mechanism. The seed charging mechanism comprises a mechanical translational motion driving mechanism fixedly connected with the side wall of a seed charging box, a translational motion sliding piece mechanism is arranged on the opposite side of the mechanical translational motion driving mechanism, the translational motion sliding piece mechanism comprises a U-shaped sliding groove and a supporting sliding piece which are fixedly arranged, the supporting sliding piece is horizontal, one endof the supporting sliding piece is horizontally fixed on the side wall of the seed charging box, and the other end of the supporting sliding piece can slide in the U-shaped sliding groove.

Description

technical field

[0001] The invention relates to a sowing device, in particular to a precision sowing device of the air duct seed selection mechanical slide translation type. Background technique

[0002] The document number is CN208987276U, and the Chinese patent document whose disclosure date is June 18, 2019 discloses a mechanical translation type special-shaped seed single-grain precision sowing device, which has the following technical problems:

[0003] 1) In the seed selection process, the sorting box has a circular structure, the hole layout efficiency is low, and the space is not fully utilized, which may cause insufficient supply of seeds from the sorting box to the seed filling box; the selected seeds need to remove sand and dust in advance and other impurities, increasing the workload;

[0004] 2) In the seed filling process, four eccentric wheel structures are used to support the seed filling box, the flatness is significantly improved, and the installation accu...
