Strip-shaped no-tillage farm manure deep applying and ridging machine

Abstract

The invention provides a strip-shaped no-tillage farm manure deep applying and ridging machine, which mainly comprises a manure tank, a manure delivery drive device and a double-roller extrusion fertilization device, wherein the manure delivery drive device drives the double-roller extrusion fertilization device to achieve double-roller differential extrusion fertilization in the manure delivery process. According to the strip-shaped no-tillage farm manure deep applying and ridging machine, double-roller differential extrusion fertilization is achieved, the mutual rubbing effect of double rollers is generated, automatic cleaning of fertilization rollers can be achieved, and the problems that farm manure is large in fertilization amount, high in viscosity and easy to adhere and block are solved. The front treated and unbroken block farm manure is extruded and broken again through double-roller rotation of the extrusion fertilization rollers, so that decomposition of the farm manure to release the manurial effect is facilitated. In addition, a stubble cutting and ditching device and a stubble cleaning device can clean straws to two sides and form a strip-shaped operation area, so that grass is prevented from being hung on a subsoiler, the subsequent light and no-tillage seeding quality is improved and the phenomenon of ''seed airing'' caused by mixing of the straws in ridges is reduced.

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
