A belt-shaped no-till farmyard manure deep application ridge machine

Abstract

The invention provides a strip-shaped no-tillage farmyard manure deep application ridging machine, which mainly includes a fertilizer box, a fertilizer transmission device and a roller extrusion fertilization device. During the process of fertilizer transportation, the fertilizer transmission device drives the roller extrusion Press fertilization device to realize two-roller differential extrusion fertilization. The invention realizes the differential extrusion of the pair of rollers to discharge fertilizer, produces mutual rubbing effect of the two rollers, can automatically clean the fertilization roller itself, and solves the problem of large amount of fertilization, high viscosity and easy adhesion and blockage of farmyard manure; When the roller rotates, it can squeeze and crush the unbroken block farmyard manure after the front treatment, which is beneficial to the decomposition of the farmyard manure and release the fertilizer effect; in addition, the stubble breaking and ditching device and the stubble cleaning device can clean the straw to both sides to form a The belt-shaped operation area prevents deep loosening and shoveling of grass, improves the quality of subsequent no-tillage sowing, and reduces the phenomenon of "drying seeds" caused by mixing straw in the ridge.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an agricultural machinery, in particular to a strip-shaped no-tillage farmyard manure deep-applying ridging machine. Background technique [0002] In recent years, due to long-term heavy use and light cultivation, and extensive farming methods, the quality of cultivated land in North China and Northeast my country has seriously degraded, and the content of soil organic matter has declined. In order to improve the quality of cultivated land and prevent the decline of land fertility, it is necessary to implement conservation tillage on cultivated land and apply farmyard manure. The application of farmyard manure can effectively improve the properties of the soil, increase the aggregate structure of the soil and the content of soil organic matter, adjust the acidity and alkalinity of the soil, promote the activity of microorganisms, and improve the activit...

Problems solved by technology

[0003] However, during the implementation of conservation tillage, crop stalks and stubble cover the ground surface, which slows down the recovery of the ground temperature, resulting in low ground temperature during sowing, which often affects the seed emergence rate.

The existing fertilization methods of farmyard manure are mostly sprinkler fertilization, which sprinkles the farmyard manure onto the surface manually or by a sprinkler device. This method is labor-intensive, the fertilizer is spread unevenly, and the utilization rate of the fertilizer is low. environmental pollution problem

In addition, farmyard manure is highly viscous, the amount of fertilizer applied is large, the state of different types of farmyard manure is greatly different, and it is easy to be blocked during fertilization, which is also a problem in the application of farmyard manure.

[0004] In order to solve the problem of farmyard manure being sprinkled on the ground, Chinese patent CN2019 10822903.0 discloses a farmyard manure fertilization device, which includes a frame body, a rotary tillage device, a fertilization device and a driving transmission device. Fertilizer is mixed with farmland soil to complete the fertilization process, but at the same time there are disadvantages such as small amount of fertilization, large power consumption, and large amount of soil disturbance.

[0005] In order to solve the problem of farmyard manure blocking the fertilization device, Chinese patent CN201810305296.6 discloses a ridging fertilizer applicator, which includes a fertilizer discharge mechanism, a ground wheel transmission mechanism, a ridging mechanism, a fertilizer tank cleaning mechanism, etc., and the machine is cleaned with water. Anti-blocking, but also has disadvantages such as low reliability, and can only be operated on land after plowing, not suitable for land without less tillage

[0006] To sum up, there is an urgent need for a deep-applied ridge-riding machine for farmyard manure, which can realize deep application of farmyard manure while carrying out ridge operation on the land without less tillage, so as to increase the amount of farmyard manure applied and solve the problem of farmyard manure blocking the fertilization device The problem
