Embodiment 1

[0029] A seed spraying device, comprising a seed box 1, a seed tank 2, a spray pipe 3 and an air blowing device 7; the seed box 1 is located above the seed tank 2, and the seed tank 2 communicates with the spray tube 3 through a seed guide tube 8, The air blowing device 7 communicates with the injection pipe 3 through a pipe to blow the seeds falling from the seed tank 2 into the injection pipe 3 . The bottom end of the seed introduction tube 8 is provided with a collection box 4 . Described seed guide pipe 8 is provided with the photoelectric sensor 5 that is used to detect seed passing situation and the synchronizer 6 that the electric signal of photoelectric sensor 5 is synchronized with the switch signal of blowing device 7 at the communication place of described seed introduction pipe 8 and injection pipe 3; The outlet of the spray pipe 3 is inclined downward.

[0030] The photoelectric sensor 5 is a reflector type photoelectric switch or a diffuse reflection type photoe...

Embodiment 2

[0034] A kind of rice seed sowing method, comprises the following steps:

[0035] 1) Seed selection and coating; the seed selection utilizes conventional seed selection methods to make the seeds clean to 100%, and the conventional seed selection methods include wind selection, water selection, salt selection and color selection. The coating agent for the seed coating is a chemical agent with a warning color, and the coating method can be manual coating or mechanical coating. The chemical agent can be selected from Dr. Miao and Hanyu Nanny.

[0036] 2) Manufacture of seed spraying device;

[0037] 3) Jet seeding.

[0038] The jet sowing is that when the seeds pass through the jetting device, the photoelectric sensor automatically detects the passing of the seeds, and sends an electrical signal to the synchronizer, and the synchronizer sends a switch signal to the air blowing device after receiving it, and completes a spot jet sowing.

[0039] For sowing on the seedling tray, ...

Abstract

The invention discloses a seed spray device and a sowing method. The seed spray device comprises a seed box, a seed groove, an spray pipe and a blowing device, wherein the seed box is located above the seed groove; the seed groove is communicated with the spray pipe through a seed guidance pipe; the blowing device is communicated with the spray pipe through a pipeline to blow seeds falling down from the seed groove into the spray pipe. The blowing device of the seed spray device blows the seeds falling down from the seed groove into the spray pipe through the pipeline, and then the seeds fall into a field to achieve precise sowing, thus achieving the effects of saving the seeds, improving the efficiency and increasing the yield.

Description

technical field [0001] The invention relates to a seed spraying device and a sowing method, which belong to the technical field of sowing, and are especially suitable for precision sowing of rice seeds. Background technique [0002] With the reduction of rural labor force and the increase of labor cost in our country, improving crop production efficiency through mechanization is an important measure to promote stable grain production and increase farmers' income. In order to ensure the smooth progress of mechanized production, high-quality seedlings are an important prerequisite. In the same ecological region, how to achieve the consistency of the growth and development of crops, especially rice crops, is the basis for the uniformity, uniformity and growth of young (seedling) seedlings. [0003] Therefore, mechanized rice transplanting proposes new and higher requirements to existing sowing techniques. [0004] Taking rice as an example, mechanized seedling raising in prod...
