Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by taking the adhesion characteristic test between rapeseed extracts and common sieve plates as an example and in conjunction with the accompanying drawings.

[0026] Step 1: mix the wet and viscous rapeseed material 5 evenly and put it into the material container 4, and place the material container 4 horizontally directly under the loading chuck 1;

[0027] Step 2: Put the ordinary sieve plate A flat on the wet sticky rapeseed material 5 and directly below the loading chuck 1, and control the loading chuck 1 through the computer 6 to apply a constant force of 200N to the adhesion interface and keep it for 60s. Then unload slowly and uniformly;

[0028] Step 3: Slowly remove the ordinary sieve plate A and turn it over so that the side of the ordinary sieve plate A in contact with the wet and sticky rapeseed material i...

Abstract

The invention discloses an adhesion property testing device for clammy materials and an adhesion property testing method for the clammy materials, which are mainly used for the field of testing adhesion properties of agricultural materials to solve the problem that a traditional adhesion property testing device and a traditional adhesion property testing method are inadaptable to testing the adhesion properties of the agricultural materials. The adhesion property testing device comprises a loading time-keeping device, a computer and an image acquisition system. The testing method based on the adhesion property testing device includes: acquiring images of adhesive materials on the surface of an adhesive plate and performing feature extraction and binarization processing for the images; sequentially computing the number of feature pixels, the actual area of remaining adhesive materials and adhesion rate defined by the adhesion property testing deviceto accordingly obtain the adhesion properties of the clammy materials. The novel testing method is provided for follow-up study based on the adhesion properties of the agricultural materials, and can be used for solving the problem that the traditional adhesion property testing method is inadaptable to testing the adhesion properties of the agricultural materials.

Description

technical field [0001] The invention relates to a device and method for testing the adhesion characteristics of wet sticky materials, in particular to a device and method for testing the adhesion characteristics of agricultural materials based on image technology. Background technique [0002] Agricultural engineering related research often involves wet sticky agricultural materials, especially the study of adhesion characteristics of wet sticky agricultural materials. For example, when harvesting machinery is harvesting super rice and rapeseed, the cleaning screen must screen and clean the wet sticky super rice extracts and rape extracts, which often causes the problem of adhesion and blockage on the screen surface. This requires research on wet sticky extracts Adhesion characteristics and follow-up research on viscosity reduction and drag reduction. [0003] In the field of agricultural engineering, the traditional test method of adhesion characteristics is based on the t...
