Novel single-grain wheat precise seed metering device

Abstract

The invention discloses a novel single-grain wheat precise seed metering device. The device mainly comprises a seed metering device casing, a seed guide rod, a seed protecting piece, bolts, a rubber seed scraping piece, a seed metering wheel, nuts, a seed metering device end cover and a seed protecting piece positioning rod, and is characterized in that the seed metering wheel is installed on an external power square shaft, the rubber seed scraping piece is fixed on a seed metering device casing through bolts and nuts, a molding hole of the seed metering wheel is used for filling seeds, and the seed metering device casing and the seed metering device end cover are connected with each other through bolts. A plurality of elliptic holes are formed in the seed metering wheel and used for filling seeds; the working face of the seed metering wheel adopts a V-shape and U-shape combination, and a V-shaped curved surface guides the seeds to enter a U-shaped groove, so that the long axes of theseeds are arranged in low linear order along the U-shaped groove of the seeding wheel; the seed guide rod pushes the seeds in the V-shaped curved surface to increase the seed filling efficiency.

Description

technical field [0001] The invention relates to a sowing machine, in particular to a novel einkorn wheat precision barley metering device, which belongs to the field of agricultural machinery. Background technique [0002] The area of ​​wheat breeding plots generally ranges from 5 to 30 square meters, and the distance between plots is 50 to 100 cm. The width of the plot is selected according to the cutting width of the plot combine harvester and the local test requirements. The length and width ratio of the strip plot is usually 2:1~5:1. The length of the community is generally about 3 to 10 meters, and the longest will not exceed 20 meters. [0003] In agricultural scientific research activities, field experiments are often encountered, such as various field comparative experiments, variety comparison yield identification, scientific research workers engaged in the cultivation of new crop varieties, often need to carry out modularized field management of different types of...

AI Technical Summary

Problems solved by technology

In the case that the sowing amount of each plot is erratic, it is necessary to sow the prepared specified number of seeds completely and evenly in the corresponding plot when sowing, and the plot seeder equipped with an air vertical seed meter The plots that are too large or too small can’t be adapted. If there is no seeder suitable for small plots, we can only use manual ditching, zone division, and manually sprinkle a certain amount of seeds in the sowing ditch, and then artificially cover the soil.

The amount of labor is large, it is easy to cause artificial misseeding, and the quality of sowing is poor, which directly affects the accuracy of the test
