Automatic metering type single-plant soybean thresher

Abstract

An automatic metering type single-plant soybean thresher comprises a machine frame. An automatic metering device and a power driving device are arranged on the bottom of the machine frame. A threshing device is arranged on the upper portion of the machine frame. A power output end of the power driving device is in transmission connection with a power input end of the threshing device. A feeding opening is formed in the top of the threshing device. A concave plate screen is arranged below the threshing device. A cyclone separation device which is placed between the threshing device and the automatic metering device is arranged on the machine frame. An inlet of the cyclone separation device is connected with a flow guiding structure placed below the concave plate screen. An outlet of the cyclone separation device is connected with an inlet of the automatic metering device. According to the automatic metering type single-plant soybean thresher, threshing is clean and complete, grains cannot be damaged, no residues exist in the thresher, sorting is clean, mixing is avoided, automatic counting and weighing are quick and accurate, a memory storing function is achieved, and after-test checking and processing are convenient.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to an automatic metering single-plant soybean thresher specially used for agricultural scientific research and breeding. Background technique [0002] Soybean is one of the crops with the richest protein content among food crops, and it is also an important source of edible vegetable oil. It is of great significance for maintaining the security of oil supply, improving the dietary structure of residents and developing animal husbandry. Soybean scientific research is an important guarantee for the safety of the soybean industry. In scientific research, soybean seed threshing and soybean yield measurement require complete, loss-free and non-mixed threshing and accurate counting and weighing of a large number of single plants, plant rows or a small amount of test materials. [0003] At present, in the process of soybean breeding and yield measurement for scientific resea...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of soybean breeding and yield measurement for scientific research in my country, there are few special equipment. The threshing work of a single plant is usually done manually or by ordinary threshers, while the metering work is completely done manually.

Using artificial threshing, the efficiency is low, it takes a long time, the damage to the grain is small but the indirect loss is large, and the comparability of the test data is poor.

Common soybean threshers are used for threshing, and the damage and entrainment loss of the grains are relatively large. After the operation, it is difficult to clean the inside of the machine, and the residual amount of grains is large, resulting in poor reliability of the experimental data.

Due to long-term observation and counting during manual measurement, it is easy to cause visual and brain fatigue, which will affect the accuracy of measurement

In addition, the efficiency of manual measurement is low, which affects the process of the whole test
