Embodiment 1

[0037] Embodiment 1: This embodiment aims to provide a low-position belt clip type seed meter suitable for multi-grain seed collection and precise sowing. It is mainly used in the field of seeders. High speed, precision and economy are the development directions of precision seeders. However, as the operating speed increases, the uniformity of the sowing grain distance will decrease significantly. How to make the seed flow fall into the seedbed uniformly is the focus of the research of the planter. Based on the existing sowing structure, the phenomenon of seed jumping is prone to occur. The embodiment provides a low-position belt-clamp type seed metering device suitable for multi-seed collection and precision sowing.

[0038] Such as Figure 1-7 Shown in , a low-position clamp-type seed metering device suitable for multi-grain seed collection and precision sowing, including a seed metering mechanism 1, a seed feeding mechanism 2, and a power mechanism 3; the seed metering mech...

Embodiment 2

[0050] Embodiment 2: This embodiment is basically the same as Embodiment 1, the difference is that this embodiment further explains the structure of the shaped hole.

[0051] In this example, if Figure 11-13 As shown in , the type hole 108 includes three seed grooves arranged side by side, two seed holders are provided with two, the fixed plate 109 is fixed on the entity between the seed grooves, and the two sides of the supporting plate 110 correspond to the seed grooves on both sides. Partially blocked, there is a gap between the supporting plates, and there is also a gap between the supporting plate 110 and the front shell and the rear shell, so that the single seed storage area is partially leaked; at the same time, a seed unloading plate 114 is provided at the seed unloading port 116 The bottom of the seed unloading plate 114 is provided with unloading teeth 115 corresponding to the seed groove.

[0052] When this embodiment is implemented, the unloading teeth 115 can c...

Embodiment 3

[0055] Embodiment 3: This embodiment is basically the same as Embodiment 1, the difference is that this embodiment further explains the installation method of the seed support platform.

[0056] In this embodiment, a plurality of gradient adjustment holes are provided on the seeding tray 107, and fixing holes corresponding to the adjustment holes are provided on the fixing plate, and the fixing holes and the adjustment holes are fixed together by connecting bolts.

[0057] In this embodiment, the installation position of the seed support platform can be selected, so that the size of the single seed storage area can be adjusted, and adaptive adjustment can be carried out for seeds of different sizes.

Abstract

The invention discloses a low-position belt clamp type seed-metering device suitable for multi-seed hole collection and precision seeding. The low-position belt clamp type seed-metering device comprises a seed-metering mechanism, a seed throwing mechanism and a power mechanism, the seed metering mechanism comprises a front shell, a rear shell, a seed metering disc, a seed supporting table, a seed protecting plate and a seed unloading plate; the seed feeding mechanism comprises a seed feeding shell and a seed feeding belt; the upper part of the seed throwing shell is communicated with the seed discharging opening, the seed throwing belt comprises two clamping and conveying belts which act synchronously, the two clamping and conveying belts are provided with an upper driving wheel and a lower driven wheel which correspond to each other, the inner ends of the two upper driving wheels are in transmission connection through a synchronous gear, and the power mechanism comprises a seed throwing wheel, a seed metering wheel and a power wheel; the power wheel is in transmission connection with one end of the seeding rotating shaft through a chain; the seed feeding rotating shaft is sleeved with a seed feeding wheel, the seed metering rotating shaft is sleeved at the other end of the seed metering wheel, and the seed feeding wheel is in transmission connection with the seed metering wheel through a chain; according to the seed feeding device, seeds are fed in the mode that the synchronous belt clamps the seeds, the conditions of bounce, collision and the like of the seeds in the seed feeding process are avoided, and accurate seed feeding is achieved.

Description

technical field [0001] The invention belongs to the technical field of seed metering devices, and in particular relates to a low-position belt-clamp type seed metering device suitable for multi-grain seed collection and precision sowing. Background technique [0002] With the expansion of the planting area of ​​peanut, corn and bean crops year by year, mechanized precision sowing of crops is particularly important in order to increase production and save costs. Seed meter is the core component of precision seeding, its working performance directly affects the quality of seeding. The existing socket type seed metering device has a low number of single seeding, uneven seed spacing after seeding, scattered seeds, poor hole collection performance, and slow seeding speed, which cannot meet the requirements of high-speed precision seeding. [0003] At the same time, the existing seed guide device is a tube structure, and the seeds will collide with the seed guide tube and the see...
