Rotary grain grinding device having grain size screening function and used for sugarcane water-retention controlled-release fertilizer processing

Abstract

The invention discloses a rotary grain grinding device having a grain size screening function and used for sugarcane water-retention controlled-release fertilizer processing. The rotary grain grinding device comprises a device base, a screening mechanism, a supporting frame, arc-shaped blocks and a second grain grinding spindle; the supporting frame is glidingly mounted on one side of the bottom of the device base; a damper is fixed to the outer wall of one side of the supporting frame; a return spring winds around one side of the surface of the damper; a device body is fixed to one side of the top end of the device base; an abrasive particle preparation box is fixed to one side of the interior of the device body; the arc-shaped blocks are fixed to the two inner side walls of the abrasive particle preparation box at equal intervals; and an abrasive particle chamber is fixed to one side of the top of the abrasive particle preparation box. According to the rotary grain grinding device, the product quality of the water-retention controlled-release fertilizer is improved, the difficulty of cleaning the device in the later period is reduced, the operation convenience of the device is enhanced, the work of manually screening the water-retention controlled-release fertilizer again in the later period is avoided, and the operation intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of processing sugarcane water-retaining and controlled-release fertilizers, in particular to a rotary abrasive device for processing sugarcane water-retaining and controlled-release fertilizers with a particle size screening function. Background technique [0002] Chemical fertilizers have been recognized as playing a pivotal role in increasing crop production, but the current utilization rate of chemical fertilizers is less than 30%, and the rest is lost with water and soil. The application of chemical fertilizers not only causes great waste, but also pollutes soil and groundwater resources. Therefore, the development of water-retaining and controlled-release fertilizers is listed as a key development support project by the state. Sugarcane needs to use water-retaining and controlled-release fertilizers during the growth process, and abrasive devices are often used during the processing of water-retaining an...
