Wheel disc type potato seeder

Abstract

The invention relates to a wheel disc type potato seeder, belonging to the technical field of agricultural machinery. A wheel disc shaft is fixed on a wheel disc mounting frame; left- and right-side hub discs are supported on the wheel disc shaft through a cylindrical roller bearing; the left-side hub disc is connected with a left-side spoke plate; the outer edge of the left-side spoke plate is connected with a left-side fixing ring; wheel disc tines are arranged on the outer cylindrical surface of the left-side fixing ring; the right-side hub disc is connected with a right-side spoke plate; the outer edge of the right-side spoke plate is connected with a right-side fixing ring; the left side of an indented seed separation plate is connected with the inner cylindrical surface of the left-side fixing ring while the right side is connected with the outer cylindrical surface of the right-side fixing ring; upper and lower seed protection belt transmission shafts are mounted at the upper part and lower end of the wheel disc mounting frame respectively; a rubber seed protection belt is mounted between the upper seed protection belt transmission shaft and the lower seed protection belt transmission shaft; and the inner side of the rubber seed protection belt clings to the outer cylindrical surface of the indented seed separation plate. The wheel disc type potato seeder provided by the invention is convenient to mount and can realize accurate seed separation, flexible seed cleaning and seed protection and self-driving and can perfectly conform to the requirements for high-speed operation and accurate seeding of a potato planter.

Description

technical field [0001] The invention relates to an integrated sowing component assembled on a potato planter to realize sorting, clearing and sowing, in particular to a wheel-type potato seeder, which belongs to the technical field of agricultural machinery. Background technique [0002] At present, potatoes have become the fourth major staple food after rice, wheat and corn. With the rapid development of the potato industry, there is an urgent demand for mature, reliable and technologically advanced potato planting machinery in the market. The sowing quality of potato planter is directly related to the growth and yield of potatoes, and the sowing quality of potato planter mainly depends on the seeding device. Common seed metering devices on potato planters include spoon chain seed meter, spoon plate seed meter, acupuncture seed meter, disc seed meter and belt seed meter. Spoon-chain seed metering devices are commonly used, but they are prone to missed seeding during the s...

AI Technical Summary

Problems solved by technology

Spoon-chain seed metering devices are commonly used, but they are prone to missed seeding during the sowing process. The planting uniformity of the spoon-plate seed metering device is poor, and the acupuncture seed metering device has the problem of damaging potatoes and seeds. The seeding device has defects such as unstable sorting and seed damage, while the belt-type seed metering device has problems such as complex structure, inconvenient adjustment of row spacing and plant spacing, etc.
