Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a device for picking up and removing soil from straw for burning in bundles. Background Art

[0002] Straw bale burning technology is a good way to utilize straw energy. It is a technical process that collects and bales loose straw in the field and then burns it for heat. Baling straw increases energy density and reduces storage and transportation costs. At the same time, the semi-gasification combustion of the bundled straw greatly improves the combustion efficiency and boiler heating efficiency, which has good economic benefits.

[0003] However, the soil entrained and adhered by the existing straw balers during the picking and throwing process seriously affects the combustion efficiency of the straw bales, aggravates the formation of combustion ash and smoke emissions. In order to solve the problem of soil removal during straw picking and baling, the technicians conducted experimental analysis on the vibration parameters of the shovel-screen residual film recovery machine, and studied the vibration soil removal mechanism and vibration parameters of the cassava harvester; and proposed to add a vibration conveying soil removal device after straw picking and before baling. For two different yellow silage straw materials, the influence of vibration on the separation of straw and soil was analyzed through bench tests to determine the mechanical structure and operating parameters of the straw vibration soil removal device. Under the three factors of vibration frequency, amplitude and vibration duration, the soil removal rate and straw loss rate of the two straw materials were analyzed to provide a theoretical basis for improving and optimizing straw picking and baling machines. Although vibration soil removal can effectively remove the soil layer entrained inside the straw, it has limited effect on removing clay adhering to the surface of the straw.
