A variable-pitch rice groove wheel seed metering device

Abstract

The invention belongs to the field of rice seed metering devices, and particularly relates to a variable-distance rice groove-wheel seed metering device. The seed metering device comprises a seed box,a shell, seed brushes, seeding metering wheels, a blocking wheel and a seed metering hopper; the upper part of the shell is provided with the seed box; the lower part of the shell is fixed with the seed metering hopper; two sides of the shell are fixed with the seed brushes which contact the seed metering wheels; the seed metering device is characterized in that a partition plate is arranged in the middle of the seed box; a fixed plate is fixedly welded at one side of the shell; a first motor is fixed on the fixed plate; the output end of the first motor is connected with a spline shaft through a flange; the middle part of the spline shaft is a cylindrical section; the left and right sections of the spline shaft are spline sections; and a blocking wheel sleeves the outside of the middle section of the spline shaft. The beneficial effect of the seed metering device provided by the invention is as follows that the biological diversity can be realized, the seed mixing requirement can bemet, the required planting interval can be set, and the structure is simple. Through the parameter selection of the seed metering groove of the first seed metering wheel, the seeding efficiency for Zaoshan No.6 seeds reaches the optimal effect.

Description

technical field [0001] The invention belongs to the field of rice metering devices, in particular to a rice metering device with variable pitch grooved wheel. Background technique [0002] Rice plays a very important role in my country's grain production, but most areas in my country still rely on traditional cultivation methods, which are labor-intensive and inefficient. Machine direct seeding is the simplest planting method in light rice cultivation technology, and the seed meter, as a very important part in the planter, plays a decisive role in the mechanization process of planting grain. Its function and effect will directly affect the quality and cost of crop cultivation. And future quantitative work will have an impact. Seed metering devices can be divided into mechanical type, vibration type and pneumatic type according to their industrial principles. Compared with other seed metering devices, pneumatic seed metering devices have the advantages of higher usability an...
