Embodiment

[0022] Experimental biological material: 10 mature ears of rice;

[0023] Firstly, 10 cut ears of rice are dried and pretreated under normal sunlight, and then each ear of each plant is placed one by one on the rice ear lifting conveyor line of the automatic grain separation system for automatic grain separation, and the ears are collected separately. Impurity at the rod outlet and grain at the grain outlet. The grain threshing error of the system can be analyzed by analyzing the grains collected through the outlet of each ear stalk and the grain outlet. The following are the results of the system test:

[0024] Table 1 Test results

[0025]

[0026] From the test results, we analyze the error of the system, as shown in Table 2:

[0027] Table 2 Error Analysis

Abstract

The invention relates to a full-automatic grain separation system for high-accuracy single plant inspection. The system comprises a rice spike conveying line, a full grain threshing mechanism, an empty grain threshing mechanism, a vibratory screening mechanism, an air drying device and a controller, wherein a threshing part of the full-automatic grain separation system consists of the full grain threshing mechanism and the empty grain threshing mechanism; a photoelectric switch is arrange at the inlet of the rice spike conveying line; a signal wire of the photoelectric switch is connected with the input end of the controller; and signal wires of the rice spike conveying line, the full grain threshing mechanism, the empty grain threshing mechanism, the vibratory screening mechanism and the air drying device are connected with the output end of the controller. The full-automatic grain separation system has the advantages of small threshing error, high automation degree, suitability for automatic treatment on rice spikes at an early stage of the high-accuracy single plant inspection and capability of providing useful technical support for precision agricultural researches and digitized agricultural researches.

Description

technical field [0001] The invention relates to a novel threshing structure, a vibrating screening structure and a fully automatic controlled grain separation system, in particular to a fully automatic grain separation system for single plant high-precision seed testing. Background technique [0002] Separating grains from rice ears (threshing) is an indispensable pre-processing part in agricultural seed testing research, especially in high-precision seed testing research, how to automatically, efficiently, and high-precision separate grains from rice ears Separation is a technical problem worth studying and solving. First of all, the integrity of grain separation can not only ensure a better threshing effect, but also has obvious practical significance for the subsequent measurement of grain parameters such as grain length, grain width, solid grain number, and total grain number. Furthermore, the automatic realization of grain separation also provides a possibility for the...
