Anti-winding no-tillage fertilizing and seeding machine for wheat after rice in paddy field

Abstract

The invention discloses a rice stubble and wheat anti-winding no-tillage fertilization seeder for paddy fields, comprising a suspension frame, a gear box assembly, a rotary tillage assembly, a ditching screw assembly and a suppression drainage assembly; the gear box assembly It is installed on the upper part of the suspension frame, and the top of the suspension frame is provided with a fertilizer sowing box and a sowing seed box. , the bottom of the chemical fertilizer spreading box is provided with a chemical fertilizer spreading bucket, and the chemical fertilizer spreading box is equipped with a hand wheel for adjusting the seeding rate of the chemical fertilizer spreading box; the spreading seed box is provided with a sowing transmission shaft. This rice stubble, wheat anti-winding, no-tillage and fertilization seeder for paddy fields can complete the work of crushing stalks, stubble removal, weeding, ditching, fertilization, sowing and suppression at one time, and at the same time, the ground is suppressed into a V shape during suppression. The topography allows water to flow into the trenches from both sides of the paddy field, which improves the survival rate of seeds, improves the efficiency of sowing work, and reduces the cost of sowing.

Description

technical field [0001] The invention belongs to the technical field of agricultural seeding equipment, and in particular relates to a rice stubble and wheat anti-entanglement no-tillage fertilization seeder for paddy fields. Background technique [0002] Rice stubble wheat refers to growing wheat or barley after harvesting rice in a paddy field. There are rice stubble and wheat in the south and north of China, which are mainly distributed in the Yangtze River Basin. In the north of the Yangtze River Basin, rice and wheat are mainly used for double cropping. In the south of the Yangtze River Basin, except for rice and wheat. And in Shanghai, there are three crops of early rice, late rice, and wheat (or barley) a year. With the development of agriculture, the country advocates conservation agriculture production. Conservation tillage refers to comprehensive supporting measures such as low-tillage, no-tillage, surface micro-terrain modification technology, surface coverage, an...

Problems solved by technology

However, the traditional no-tillage seeder can only be used for sowing in dry land, and it cannot show good sowing effect when sowing in paddy fields, mainly reflected in: 1. The sowing process is cumbersome and the working cycle is too long, requiring fertilization and rotary tillage , ditching, sowing and suppression, and the traditional seeder cannot meet these tasks at the same time, it needs to occupy two or even three mechanical equipment for sowing work, it is difficult to improve the efficiency; 2. Due to the sufficient soil moisture in the paddy field, the The middle soil is mixed with water, it is muddy, and the soil has high viscosity. It is inevitable that the muddy soil will stick to the top of the ground wheel during the process of sowing or fertilizing. At this time, a mud scraper is needed to scrape the sticky soil on the suppression drainage device. However, the mud scraper in the prior art cannot completely remove the mud stuck on the ground wheel, and there is a phenomenon of missing scraping; 3. Due to the excessive moisture in the paddy field, the traditional seeder cannot meet the drainage requirements during the paddy field sowing process. Need, it needs to be drained separately before or after sowing, which increases the sowing cycle, and too much water will cause low seed survival rate
