Description

technical field [0001] The invention belongs to the field of agricultural harvesting machinery, and relates to a double-knife parallel-cut harvester for cutting and crushing stalk-like silage feed. Background technique [0002] In recent years, with the vigorous development of animal husbandry in the vast rural areas of our country, the demand for animal stalk silage feed is increasing day by day. At present, imported machinery is generally used for cutting and crushing stem crops in my country. The imported machinery with high-power transmission is expensive and the cost of use is high. The price of harvesting one hectare of stem green storage crushed feed is about 900 yuan. Most livestock breeding professionals can't afford it. [0003] Existing imported silage harvester and the stalk pulverizer of domestic manufacture, its base knife all adopts fixed straight line edge blade, and upper knife is a moving knife, adopts two kinds of rotary straight line edge blade or curved ...

Problems solved by technology

Because most of our country uses green storage corn as the main feed for livestock, this kind of crops have high planting density and high stems. Usually, about 24 plants are planted per meter distance, and the plant height is 3-4 meters, which makes the feeding volume of the machine larger. As a result, the stalk gradually slides on the fixed linear blade with the pressure of the moving knife to produce a sliding cut. When the stalk is bitten and cut to a certain extent, there is a large cutting resistance and a large power consumption. The mechanical horsepower driving the conveying rotation must be It is high-horsepower rotation, high manufacturing and use costs, uneconomical and other deficiencies, and is not suitable for the harvesting and crushing of stalk-based silage feed for livestock in my country.
