Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural film light transmittance detection technology, especially relates to a plastic agricultural film light transmittance detection equipment. BACKGROUND

[0002] The principle of plastic agricultural film light transmittance detection is mainly to evaluate the light transmittance by measuring the intensity of light after the light transmits through the agricultural film, mainly the light emitted by the light source passes through the plastic film, and the light intensity after transmitting through the film is compared with the initial light intensity of the light source.

[0003] When using the light transmittance method to detect the light transmittance of the plastic agricultural film, some agricultural films have wrinkles and are not tight, which will increase the light scattering, and the light will be scattered irregularly when passing through the plastic film. The scattered light cannot be effectively detected, resulting in a decrease in the measured value of the transmitted light, and thus the light transmittance is reduced. Therefore, the change of the light path caused by the wrinkles on the surface of the plastic film may make the light signal received by the photoelectric detector unstable, increasing the measurement error, especially in high-precision measurement.
