Feeding structure, feeding device and seed testing machine

Abstract

The invention discloses a feeding structure, a feeding device and a seed testing machine. The feeding structure comprises a fixed funnel, a flow adjusting part, a discharging plate and a first vibrator. The fixed funnel is provided with a discharging port; the flow adjusting part is used for regulating the discharge flow of the fixed funnel; the discharging plate comprises a feeding end and a discharging end, the feeding end is connected and matched with the discharging port to be used for receiving materials discharged along the discharging port, and the discharging plate is obliquely arranged at the discharging port so that the materials can be discharged towards the discharging end; the first vibrator is connected with the discharging plate and used for shaking the discharging plate so that materials on the discharging plate can be discharged to the next working procedure, and the materials can be continuously, orderly and quantitatively output. The feeding device can realize material transportation through a first conveying equipment, so that the manual labor force is reduced. The seed testing machine realizes continuous and orderly quantitative output of the materials through the feeding structure, so that a computer vision system can conveniently realize analysis of quantity and size information of the materials.

Description

technical field [0001] The invention relates to the field of agricultural seed detection, in particular to a feeding structure, a feeding device and a seed testing machine. Background technique [0002] The inspection process of rice seeds plays an important role in the breeding work. The yield and quality of rice seeds have been closely watched by researchers. The number of grains on the ear, the number of solid grains, the number of empty grains, the seed setting rate, and the weight of thousand grains are closely related to the yield. The length, width, and aspect ratio of the grains, etc. Parameters are closely related to quality. The current testing work is mainly carried out manually by a large number of scientific researchers, and the process is very laborious. In the field of rice automatic breeding test, there are very few researches and products on this. Due to the unreasonable feeding structure of the existing testing machine, the flow rate cannot be controlled...

AI Technical Summary

Problems solved by technology

[0003] Due to the unreasonable feeding structure of the existing testing machine, the flow rate cannot be controlled, and the material needs to be manually shaken. Manual feeding will easily cause too much feeding, and the phenomenon of sometimes less and sometimes more feeding will occur, which is not only time-consuming and labor-intensive , and the feed flow of grains cannot be controlled
