Problems solved by technology

This often leads to the result of the previous link having a great influence on the implementation of the next link, and the continuous implementation of each process also makes it difficult to feedback and adjust the unqualified seeding.
As a result, the pass rate cannot go up, and ultimately affects the accuracy of the plot test

Embodiment Construction

[0012] like Figure 1-5 As shown in the figure, a new type of precision seeding device for small-scale wheat firstly makes seed trays, which are divided into strip seeding trays and fine seeding trays. Strip seed tray: Take out an unfilled seed tray (consisting of elastic seed strip tray and seed box). The elastic seed strips 15 are tightly arranged, and the gap between the elastic seed strips 15 and the seed box 6 is extremely small. Take out a handful of wheat seeds and place them on the elastic seed strip 15 , scrape and spread the seeds evenly by hand, and the seeds will fall into the plastic hollow tube 14 . Due to the size limitation of the plastic hollow tube 14, only 2-3 wheat seeds are dropped into it. Or apply a certain amplitude to the seed box. When all the plastic hollow tubes 14 are filled with seeds, the excess seeds will leak out from the circular hole in the middle of the seed box 6 for recycling. At this point, the production of the strip seeding tray is ...

Abstract

The invention provides a novel plot accurate seeding device for wheat. According to a seedling process with the novel plot accurate seeding device, a plot seeding link is divided into manufacturing of a precise seed disc for sowing in strip and seedling by a matched seeding device. The two steps are respectively controlled so as to effectively avoid disadvantages of a traditional plot seeding machine that the seeding is not accurate and feedback adjustment is unlikely to be carried in a seeding link. The novel plot accurate seeding device has the characteristics of simple structure, low construction cost, convenience for utilization, high seeding precision and the like.

Description

technical field [0001] The invention relates to a novel precision seeding device for small-scale wheat, belonging to the technical field of agriculture. Background technique [0002] When conducting agricultural scientific research, a large number of plot experiments are required, and the sowing link is crucial. Manual seeding is easy to cause errors, time-consuming, labor-intensive, and inefficient, while mechanical seeding can effectively reduce experimental errors. Therefore, experts and scholars at home and abroad have done a lot of research on the precision seeding device in the community, and mainly focus on the research on the seed metering device. On the one hand, the seed metering device suitable for field sowing is designed and transformed to be applied to small-scale sowing. According to the working principle, the seed metering devices suitable for field sowing can be divided into mechanical type, pneumatic type, and seed belt seeding, magnetic seeding, liquid s...
