Striped subsoiling ridge-cleaning straw-mixing combined operation machine

Abstract

The invention relates to a striped subsoiling ridge-cleaning straw-mixing combined operation machine and belongs to the technical field of agricultural machinery. The striped subsoiling ridge-cleaning straw-mixing combined operation machine comprises a rack, a gearbox, a transmission, and a subsoiling device, a ridge cleaning device, a mixing device and a compacting device which are mounted on the rack and are sequentially arranged from the working front end to the rear end; a subsoiler of the subsoiling device and a cutterhead set of the mixing device are arranged in a furrow; the rigid cleaning device is arranged at a furrow side position; and a through shaft of the mixing device is connected with an output shaft of the gearbox by the transmission. The striped subsoiling ridge-cleaning straw-mixing combined operation machine can simultaneously complete dry farmland preparation and straw returning operations of subsoiling, ridge cleaning, mixing, compacting and the like for once in the operating process, moreover, also can achieve the effects of subsoiling, cleaning a ridge, returning straws to the field, enhancing land productivity and reinforcing soil organic matter, and effectively prevents straw burning. According to the machine developed by the invention, the combined operation of one machine is achieved, a utilization rate of a large-medium tractor is effectively improved, and the technical problems of agricultural mechanized production of a plough layer, such as subsoiling and soil improvement, interval farming, straw returning and the like, are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a strip deep loosening and ridge clearing straw mixing combined operation machine. Background technique [0002] my country's rain-fed and dry land area is 1.109 billion mu, accounting for 56.8% of the country's total cultivated land area. It is mainly distributed in the Northeast, North China, and Northwest major grain-producing areas. Its crop production has important strategic significance for ensuring national food security. However, in the past 30 years, the continuous small-scale agricultural machinery power shallow tillage and the predatory production mode of reusing farmland and ignoring cultivation have led to the deterioration of the cultivated layer environment such as shallower plow layers, thicker plow layers, weakened soil buffer capacity, and prominent contradictions between water, fertilizer, air, and heat. , The problem of declining cultivated land...

Problems solved by technology

However, in the past 30 years, the continuous small-scale agricultural machinery power shallow tillage and the predatory production mode of reusing farmland and ignoring cultivation have led to the deterioration of the cultivated layer environment such as shallower plow layers, thicker plow layers, weakened soil buffer capacity, and prominent contradictions between water, fertilizer, air, and heat. , The problem of declining cultivated land quality has become increasingly prominent

Unreasonable farming methods such as shallow plowing are commonly used in rain-fed dry land, which has caused structural problems in the plow layer. The thickness of the plow layer is generally less than 15cm. Mechanical operations and rolling at the same depth year after year also lead to an increase in the thickness and compactness of the plow bottom layer.

However, there are still some problems in the existing stubble removal machine in the process of returning to the field. For example, the straw returning to the field is shallow, and how to clear the straw within a certain width on both sides of the furrow into the furrow. At present, it still lacks high collection efficiency and low power consumption. corresponding equipment
