一种分体导种盘结构

Abstract

本实用新型涉及农用机械技术领域，具体涉及一种分体导种盘结构，其包括：转盘，所述转盘中央设有贯穿的轴套；导种环，所述导种环固定设置在所述转盘的一侧，并且所述导种环对应所述转盘边缘排列有导种室。本实用新型利用聚氨酯的材料特性，使得导种室的内壁具有足够弹性来缓冲种子的撞击，从而避免种子被指夹经抛种口弹入导种室的过程中，因多次硬碰硬的撞击而损伤种子，因此降低了种子的内部损伤，提高种子的发芽率。

Claims

1. A split-type seed guide disc structure, characterized in that, include: Turntable (1), wherein a through bushing (2) is provided in the center of the turntable (1); Seed guiding ring (3), the seed guiding ring (3) is fixedly disposed on one side of the turntable (1), and seed guiding chambers (4) are arranged on the edge of the turntable (1) corresponding to the seed guiding ring (3).

2. The split seed disk structure of claim 1, wherein: The seed guiding ring (3) is composed of a circular ring (5) and a plurality of radially distributed partitions (6) connected around the circular ring (5); any two adjacent partitions (6) together with the sidewalls of the circular ring (5) and the turntable (1) form an open seed guiding chamber (4).

3. The split seed guide disc structure according to claim 2, characterized in that: The ring (5) has mounting grooves (7) that connect to each of the partitions (6) around its perimeter. The turntable (1) has screw holes (9) corresponding to each of the mounting grooves (7). The seed guide ring (3) is connected to the turntable (1) by bolts (8) that pass through the mounting grooves (7).

4. The split seed disk structure of claim 2, wherein: Each of the partitions (6) has a rounded chamfer (10) between its two sides and the outer wall of the ring (5).

5. The split seed disk structure of claim 2, wherein: Any two adjacent partitions (6) are provided with guide slopes (11) on the side near the turntable (1), and both guide slopes (11) are concave structures.

6. The split seed disk structure of claim 2, wherein: The ring (5) and the partition (6) are integral polyurethane structures.
