Straw Compression Bundling Test Device and Test Method

Abstract

The invention discloses a straw compression forming and bundling test method which comprises a material conveying device, a filler compression device, a bundling device and a detection and control device and can be used for simulating the working conditions of a straw baling press in the field and reproducing processes of picking up, compressing and bundling during straw collection. The method comprises the following steps of: obtaining different feeding quantities by changing the layer thickness of materials on a conveying belt and the speed of the conveying belt; obtaining different compression frequencies by adjusting the rotation speed of a transmission shaft and analyzing the influence of the compression frequencies on the straw bundle quality; obtaining different compression forces by adjusting inclination angles of a press plate on a compression chamber and analyzing the influence of the compression forces on the straw bundle density and the buckling rate; and obtaining the elasticity and plasticity deformation simulation of the straws in the compression process by utilizing high-speed photography. The test device and method disclosed by the invention has the advantages of use safety, detection completeness, convenience for operation and capabilities of eliminating the defects of the traditional field test method and obtaining more detailed and scientific information.

Description

technical field [0001] The invention relates to the technical field of straw bundling test devices, in particular to a straw compression molding bundling test device. Background technique [0002] The collection, storage and transportation of crop straws has always been the primary problem restricting the industrial scale utilization of agricultural biomass resources. The development and development of balers is one of the effective ways to solve the problem of agricultural biomass straw collection, storage and transportation, and meet the industrialized utilization. At present, the research and improvement of each part of the baler mainly depends on the field test of the prototype, but the field test is affected by the climate, field conditions and the limitations of the adjustable range of the parameters of the machine itself, which makes this test method have many limitations. Certain metrics cannot be measured in real time. Mainly manifested in the following aspects: ...
