The invention provides a lepidoptera pest egg
mass lossless collection method and a portable device based on vibration separation, and relates to the technical field of pest egg
mass collection, the portable device comprises a bottom plate, a supporting rod, a side plate and a fixing piece, a sliding mechanism is arranged at the rear end of the bottom plate, a rotating mechanism is arranged in the side plate, and the sliding mechanism comprises an entering cavity, an arc-shaped hopper, an arc-shaped partition plate, a storage cavity, a screen and the like. The rotating mechanism comprises a
metal sliding block, a rotating shaft, a connecting piece, a support, an annular
magnet and the like, and is further provided with a
rotating disc, a spring, a
brush and the like. By means of the structure, after soil blocks with eggs are placed into the entering cavity and separated through the arc-shaped partition plate, the
rotating disc is rotated to enable the rotating shaft to drive the support to rotate, the
metal sliding block moves up and down to generate vibration, the soil blocks are stripped through the adjustable
brush, and the egg blocks fall into the containing cavity through the screen; the lepidoptera pest
egg masses in soil blocks with different viscosities can be conveniently, efficiently and nondestructively separated and collected, and the device is suitable for the field environment.
