A quick-change multi-variety precision seeder

Abstract

This utility model discloses a quick-change multi-variety precision seeder, relating to the field of seeder technology. It includes a base plate with a bearing seat on top. Inside the bearing seat is a seed rotor assembly, and on the outside of the seed rotor assembly are hexagonal seed blocks. A stepper motor is located on one side of the seed rotor assembly, a second synchronous pulley is located on one side of the stepper motor, a synchronous belt is located on one side of the second synchronous pulley, and a first synchronous pulley is located on one side of the synchronous belt. In this utility model, the hexagonal shaft rotates via the pulley mechanism, thereby driving the seed rotor to rotate. When the seed rotor rotates, the seeds falling within the hexagonal rod segment rotate. When the seeds rotate to the notch position in the seed box, they fall into the seed box's sowing pipe under gravity and then into the prepared trench along the sowing pipe. When changing varieties, simply remove the magnetic suction plate and rotate the multi-faceted prism seed hole to adjust the appropriate seed hole size, enabling the sowing of different varieties.

Description

Technical Field

[0001] This utility model relates to the field of seeders, and in particular to a quick-change multi-variety precision seeder. Background Technology

[0002] Sowing generally includes two methods: mechanical sowing and manual sowing. Mechanical sowing is more commonly used in flat areas with large sowing areas. However, due to limitations such as terrain, mechanical sowing is difficult to apply in some areas. Manual sowing, on the other hand, is more flexible, allowing for adjustments to sowing density based on the specific terrain of the sowing area, and is therefore more widely applicable. Afforestation through sowing is an important means of improving the ecological environment in barren mountains and deserts, where conditions are complex, thus manual sowing is generally employed.

[0003] The existing quick-change multi-variety precision seeder cannot adjust the hexagonal rod according to the size of the seeds, nor can it sow different varieties, which brings certain disadvantages to the user experience. In order to overcome the shortcomings of the existing technology, we propose a quick-change multi-variety precision seeder. Utility Model Content

[0004] The main objective of this invention is to provide a quick-change multi-variety precision seeder, which can effectively solve the problems in the background technology.

[0013] 1. In this utility model, a first synchronous pulley, a synchronous belt, a second synchronous pulley, and a stepper motor are provided. The rotor assembly unit of the seeder is externally connected to a motor and a synchronous pulley. The synchronous belt rotates through the pulley mechanism, which drives the internal seed rotor to rotate. When the seed rotor rotates, the seeds falling into the groove of the hexagonal bar segment rotate accordingly. When the seeds rotate to the notch position of the seed box, they fall into the seed box sowing pipe under gravity and fall into the prepared groove along the sowing pipe. When changing varieties, it is only necessary to remove the magnetic suction plate and rotate the polygonal prism seed hole to adjust the appropriate seed hole size to achieve sowing of different varieties.
