Description
Technical Field
[0001] The utility model relates to the technical field of double-drive medicinal fertilizer processing, in particular to a multi-stage screening device for medicinal fertilizer particles used in double-drive medicinal fertilizer processing. Background Art
[0002] Double-drive pesticide fertilizer is a new type of ecological compound fertilizer. It is a product formed by mixing pesticides and fertilizers in a certain proportion and stabilizing the fertilizers and pesticides in a specific compound system through certain process technologies. This type of fertilizer generally uses fertilizer as a carrier of pesticides. It aims to promote the sustainable development of contemporary agriculture and provide a new attempt for modern agriculture. The particles of newly made double-drive pesticide fertilizer are irregular in size and need to go through three levels of screening to select fertilizer and particles that meet the requirements. The first level screen screens out irregular large particles, the second level screen screens out regular but larger particles, and the third level screen screens out smaller particles or dust. Only the particles remaining between the second and third level screens are particles that meet the pesticide fertilizer standards.
[0003] The prior art has a publication number of CN219445764U. The technical solution disclosed in this patent document is as follows: a multi-stage vibration screening device for plastic particles, including a screening box, a screening box installed inside the screening box, a support plate provided below the screening box, and a first discharge port provided on the side of the screening box. The bottom end of the screening box of the utility model is connected to a spring and a tension spring respectively, and the recycled PE particles fall into the screening box. The two ends of the screening box are rotated by cams, and the reciprocating upward and downward movement and left and right flipping are used to keep the recycled PE particles shaking and rolling left and right in the screening box for full screening. A screening box with a rectangular frame structure is used, and a first discharge port is provided on one side of the screening box. A baffle plate covers the first discharge port. When the recycled PE particles are screened in the screening box, the material will not fall out. After the screening is completed, the baffle plate is opened to control the discharge of the recycled PE particles after screening.
[0004] The above technical solution screens the particles by shaking and rolling left and right, but the connection between the screening box and the discharge port is not good. The particles that meet the standards are easy to fall during discharge, affecting the effect of the multi-stage vibration screening. In addition, since the particles are mixed with dust, the dust is discharged from the discharge pipe and the feed hopper, which is difficult to clean and affects the surrounding air quality.
