[0002] Crop fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production. During production, the standard particles of crop fertilizer have a certain particle size range. Particles exceeding this size range are called larger particles. Their decomposition period in the soil is too long, which is not conducive to the absorption of crops during the growth cycle. Therefore, it is necessary to detect the proportion of fertilizer particles of different particle sizes.

[0003] During use, the filter screen and tank of some existing devices are usually fixed, and manual stirring of the fertilizer is required to speed up the screening speed of the device. However, manual stirring is time-consuming and labor-intensive, and can easily cause the fertilizer to break, affecting the accuracy of the detection. Utility Model Content

[0030] There are two chutes 13 , which are symmetrically arranged about the center of the U-shaped frame 12 . There are two slide bars 14 , which are both located at the center axis of the chutes 13 .
