Wide zero tillage fertilizing seeder

Abstract

The invention provides a wide zero tillage fertilizing seeder which comprises a machine frame, an universal drive shaft and a suspension arm are mounted at the front end of the machine frame, a speed changing box, a fertilizer box and a seed box are mounted at the middle part of the machine frame, a rotary blade is mounted at the bottom of the machine frame, the rotary shaft is connected with the output shaft of the speed changing box, the cutting edges of the rotary blade are sawtooth-shaped, a suppress wheel carrier is mounted at the rear end of the machine frame, and suppress wheels are mounted on the suppress wheel carrier; a fertilizer conveying tube is arranged at the bottom end of the fertilizer box, a fertilizer conveying tube is arranged at the bottom end of the seed box, the bottom end of the fertilizer conveying tube is lower than the bottom end of the seed conveying tube, and the fertilizer conveying tube and the fertilizer conveying tube are mounted on the machine frame through a bracket. The arrangement of the saw tooth on the rotary blade can increase the cutting strength to straws or weeds, smash straws or weeds forcefully, avoid the increasing of the number of the rotary blade, keep larger bandwidth, and is beneficial to the growth of crops in the future, ventilation and light transmitting between the lines, increasing of yields, especially in winter, permeability of the soil is decreased, so that the temperature decreases slowly, and the crop freeze injury is avoided accordingly.

Description

technical field [0001] The invention relates to an agricultural machine, specifically a wide-width no-tillage fertilizing seeder. Background technique [0002] Fertilizer seeder is a commonly used equipment in agricultural production. It can help farmers reduce labor burden and speed up sowing efficiency. It is an important mechanical equipment in agricultural mechanization. In areas with a lot of straw or weeds, the cutting ability of the rotary blades of the existing seeder is limited, and the straw or weeds that can be cut are limited, so the distance between the rotary blades can only be reduced to increase the The number of knives. This method leads to narrower bandwidth, unfavorable ventilation and light transmission between rows, and easily causes stems and leaves at the base of crops to rot and many spikelets to drop. Crop damage is prone to occur. In order to increase bandwidth, farmers will use straw burning, which seriously pollutes the environment. Although ...
