Rapid detection device for pyrethroid pesticide residues in pasture in livestock farm

The invention provides a rapid detection device for pyrethroid pesticide residues in pasture of a livestock farm, and relates to the technical field of pesticide detection. The rapid detection devicefor pyrethroid pesticide residues in pasture of the livestock farm comprises a shell, a juicing barrel is arranged in the shell, an electric telescopic rod is fixedly connected to the inner bottom face of the juicing barrel, and a filter plate is fixedly connected to the end, away from the juicing barrel, of the electric telescopic rod. Forage grass is crushed and minced in the juicing barrel; forage grass juice is obtained under the filtration of the filter plate, the forage grass juice is treated for different time by a decompression dryer to obtain forage grass juice with different concentration degrees, and after the forage grass juice is quantitatively dripped onto bodies of forage grass pests in a detection tank, the effect on the forage grass pests can be directly observed, so thatthe natural decomposition
