Wide-narrow dual-row ridging seed pre-cutting type cassava planting machine

Abstract

The present invention discloses a wide-narrow dual-row ridging seed pre-cutting type cassava planting machine. The wide-narrow dual-row ridging seed pre-cutting type cassava planting machine comprisesa frame, land wheels, a transmission system and a rotary plate type seeding device, wherein the top side of the frame is provided with the rotary plate type seeding device; the bottom side of the frame is provided with the land wheels; and the land wheels drive the rotary plate type seeding device to rotate through the transmission system. In a manner of pre-cutting cassava seed stalks into seedstems with the lengths of 15-20 cm, a seed-metering mode of a real-time seed cutting type cassava planting machine is changed by the rotary plate type seeding device. The wide-narrow dual-row ridgingseed pre-cutting type cassava planting machine has the characteristics of simple structure, high working stability, uniform and accurate seeding, high efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a wide-narrow double-row ridge pre-cut cassava planter. 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, and an important food crop and energy crop in many tropical and subtropical countries. In the subtropical regions of my country, cassava is the fifth largest crop after rice, sweet potato, sugar cane and corn, and is mainly planted in Guangxi, Yunnan, Guangdong, Hainan and other regions. Cassava cultivation is one of the most important steps in cassava production, accounting for 12% of cassava production operations. At present, cassava planting mainly relies on manual planting, and cassava planting machin...

AI Technical Summary

Problems solved by technology

The existing real-time seed-cutting cassava planters have problems such as high seed damage rate, low uniformity, and uneven cutting length, which restrict the production quality and efficiency of cassava planters

In order to promote the integration of agricultural machinery and agronomy, Deng Qianran et al. proposed an agronomic model of cassava wide and narrow double-row ridge planting suitable for full-scale mechanized operations, which can effectively alleviate the mismatch between the traditional cassava flat planting or small ridge average row spacing and the mechanized tractor wheelbase. question

[0003] This application proposes a wide and narrow double row ridge pre-cut cassava planter. Based on the agronomic mode of cassava wide and narrow double row ridge planting, the cassava seed stalks are cut into 15-20cm seed stems in advance to ensure the uniform length of the seed stems. Through the high-quality screening of cassava seed stems, the injury rate of real-time seed-cutting cassava planters can be reduced, and the emergence rate of cassava can be improved; the cassava seed stems are packed in a transport frame, and the transport frame is placed on the seed frame of the planter On the top, the operator takes out the cassava seed stems from the transport frame and puts them into the seed cup of the seed meter, and the cassava seed stems are discharged into the planting ditch one by one by the seed cup, so as to realize the precise planting of cassava seed stems and improve the quality of cassava seeds. The seeding uniformity of the planter, changing the seeding method of the cassava planter, and solving the problems of real-time cutting cassava planter damage, uneven cutting length, and low planting uniformity
