Precut type cassava seed stem seeding device

Abstract

The invention discloses a precut type cassava seed stem seeding device. The device comprises a base plate, a seed feeding groove, a grooved pulley, a grooved pulley shaft, a seed protective plate anda seed guide groove, wherein the grooved pulley shaft is horizontally arranged on the base plate; the grooved pulley is arranged on the grooved pulley shaft; a cassava seed stem groove is formed in the grooved pulley; the opening direction of the cassava seed stem groove is the tangent direction of the circumference of the grooved pulley; a land wheel is transmitted to a chain wheel in a powered manner through a chain; the chain wheel is used for driving the grooved pulley shaft to rotate; the grooved pulley rotates along with the grooved pulley shaft; cassava seed stems slide along the linearsection of the seed feeding groove, and enter the cassava seed stem groove of the grooved pulley through the arc section of the seed feeding groove; the cassava seed stems outside the cassava seed stem groove are retained in a seed cleaning area by the seed protective plate; when the cassava seed stems in the cassava seed stem groove pass through the seed protective area, the cassava seed stems are prevented from falling off by virtue of the seed protective plate; and when the cassava seed stems are rotated to the seed launching area by the grooved pulley, the cassava seed stems fall into a planting trench through the seed guide groove. The precut type cassava seed stem seeding device has the characteristics of simple structure, good work stability, uniform and accurate seed arrangement and high efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a cassava seed stem seeding device. Background technique [0002] Cassava, also known as cassava, cassava, cassava, has the reputation of "underground granary", "king of starch" and "special crop". It is also known as the world's three major potatoes together with sweet potato and potato. , ethanol alcohol, an important raw material for feed, widely planted in tropical and subtropical regions, the planting area of ​​the world is about 20 million hm 2 , the output is about 250 million tons. In the southern subtropical region of my country, cassava is the fifth largest crop after rice, sweet potato, sugar cane and corn. It is mainly planted in Guangxi, Yunnan, Guangdong, Hainan and other regions. The annual planting area in the country is about 450,000 hm 2 , the output is about 8.5 million tons. Since 2005, my country has become the world's largest importer of ca...

AI Technical Summary

Problems solved by technology

The existing cassava planter seeding devices rely on manual feeding of whole cassava stems into the seeding device for real-time cutting and seeding, requiring up to 5 people to assist labor, which has high labor intensity, high seed damage rate, and missed planting. The problems of high yield and low uniformity restrict the production efficiency of cassava planters
