Problems solved by technology

[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 accuracy is high. If there is an installation error, one of them is a driving wheel and the other three are driving wheels. During work, self-locking phenomenon is prone to occur, which affects the reliability and stability of the equipment, and there is a risk of early damage; according to different seed requirements, if the eccentric support is replaced to adjust the rotation diameter of the seed filling box, four eccentric supports need to be replaced at the same time, greatly Added requirements for installation accuracy;
[0005] 3) In the connection between filling and unloading, the reset of the upper cover and the lower bottom completely depends on the return spring, and the reliability is difficult to guarantee; the material of the upper cover and the lower bottom is opaque, and it is not convenient to observe the seeds in the process of filling and unloading status

Embodiment 1

[0030] Seed selection agency part:

[0031] see Figure 1-4 , the funnel 1 is installed on the seed clearing frame 5; the bottom end of the funnel 1 is provided with a guide groove, and the seeding rate adjustment plate 2 is installed in the guide groove at the bottom end of the funnel 1; the fan 3 is installed on the seed clearing frame 5; On the seed rack 5; the conveying pipe 6 is installed on the seed clearing rack 5; the three-stage sorting box 9 is installed on the seed filling box 10; the second-stage sorting box 8 is installed on the third-stage sorting box 9; Box 7 is installed on the secondary sorting box 8.

[0032] Part of the filling mechanism:

[0033] Drive motor 15 is installed on the frame 16; Gear one 14 is installed on the drive motor 15, and gear two 13 is installed on the eccentric support 12, is concentric with eccentric support 12 main shafts, and gear one 14 and gear two 13 form gear pair, for driving Motor 15 transmits power to eccentric support 12;...

Embodiment 2

[0040] What this embodiment is aimed at is that hole size is bigger, or the seed of low-density sowing, such as super rice, vegetable seed etc., the difference between this embodiment and embodiment 1 is: do not arrange seed drop frame and drop seed platform. see Figure 7 , the bottom of the seed filling box 10 is directly provided with a hole tray. Mainly for low-density sowing seeds, such as cucumber, tomato, pepper and other vegetable seeds, etc., the eccentric support with small eccentricity is selected to complete the low-amplitude and high-frequency seed filling process. The compound movement is performed within the projection range of the hole size. When the upper cover plate is closed, the lower bottom plate opens the door, and the seeds fall freely into the hole to complete the sowing process; the reciprocating linear motion of the opening and closing mechanism of the upper and lower bottom plates of the seed filling box can be See the closest prior art cited in the...

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...
