Screening equipment capable of keeping fertilizers dry

Abstract

The invention discloses screening equipment capable of keeping fertilizers dry. The screening equipment comprises a cylinder; a rotating shaft is arranged in the cylinder; a mounting plate is arrangedat the top of the rotating shaft, and is hinged with a first filter screen; mounting grooves are formed in two sides of the inner wall of the cylinder; connecting shafts are arranged in the mountinggrooves; the two ends of the first filter screen are connected with two connecting shafts; the first filter screen and the connecting shafts are connected through elastic elements; a second filter screen is arranged under the first filter screen, is connected with the rotating shaft, and can be rotated along with the rotating shaft; and multiple drying devices are arranged in the cylinder. Throughcombined effects of the first filter screen and the second filter screen, the screening rate of the fertilizers can be increased; and through the drying devices, the fertilizers are kept dry, and areprevented from bonding on the filter screens to block the filter screens.

Description

technical field [0001] The invention relates to the field of agricultural tools, in particular to screening equipment capable of keeping fertilizers dry. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production, mainly including ammonium phosphate fertilizers, water-soluble fertilizers with a large number of elements , Medium element fertilizers, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. As early as the Western Zhou Dynasty, China already knew that weeds in the field can promote the growth of millet after they rot. "Qi Min Yao Shu" introduced in detail the method of planting green manure and the method of crop rotation between legumes and grasses; Also mentioned is the method of using crop stalks mixed wi...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that if the humidity of the fertilizer is too high when the fertilizer is passed through the screen in the existing fertilizer screening device, it is easy to stick to the screen, and long-term use will easily cause the fertilizer to block the screen and affect the passing of the fertilizer. The problem of sieving rate is to provide screening equipment that can keep the fertilizer dry to solve the above problems
