Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a three-point suspension type quinoa seeder. Background Art

[0002] Quinoa, also known as Indian wheat, belongs to the dicotyledonous plant family and is native to mid-to-high altitude regions such as Colombia and Peru. Quinoa possesses certain characteristics such as cold tolerance, drought tolerance, and resistance to salinity. Since its introduction to my country in the 19th century, its cultivation has been relatively short, resulting in a lack of a relevant planting system and automated agricultural machinery for sowing and harvesting. Furthermore, the limited number of rural laborers has increased the cost of quinoa production, especially during sowing and harvesting, which has, to a certain extent, slowed the goal of achieving prosperity through quinoa cultivation.

[0003] At present, my country's quinoa planters are relatively traditional, with relatively simple functionality and low intelligence. When sowing, it is often difficult to adjust the sowing amount and the sowing depth, and the maintenance cost is high. Secondly, in areas with large slopes such as hills, the mechanized site conditions are poor, and the operation of the planter will be greatly limited. For example, a quinoa planter disclosed in the Chinese invention patent application document with patent number CN202220203711.9 effectively solves the problems of long quinoa seedling emergence time and large and small seedlings, but the overall function of the machine is relatively simple and the sowing efficiency is also low. Another example is a multifunctional quinoa planter disclosed in the Chinese invention patent application document with patent number CN201810941089.X. Since the sowing mechanism of the planter is a seeding tube, it cannot flexibly adjust the sowing amount, making it difficult to meet different production needs. Therefore, designing a quinoa planter that is intelligent, comprehensive, and highly adaptable to terrain is of great significance to the sowing of quinoa. Utility Model Content
