Linkage control type finished product crushing and screening machine

Abstract

The invention discloses a linkage control type finished product crushing and screening machine. The screening machine comprises a blanking mechanism and a screening mechanism, wherein the blanking mechanism comprises a blanking hopper and a blanking hopper fixing frame; the bottom end of the blanking hopper is provided with a blanking opening; a blanking switch is arranged in the blanking opening; the screening mechanism is arranged below the blanking hopper; the blanking switch is a first electromagnetic valve; a pressure sensor is arranged below a first-stage filtering screen; both the first electromagnetic valve and the pressure sensor are connected with a PLC (Programmable Logic Controller); when the weight of materials carried by the first-stage filtering screen reaches a threshold value according to detection, the switching value of the first electromagnetic valve is adjusted through the PLC. Through linkage control of the electromagnetic valve and the first-stage filtering screen, the blanking adjustability of the blanking hopper is realized, and the efficiency is high; moreover, separation of three size stages of particles is realized through a simple structure, a good screening effect is achieved, the equipment maintenance cost is low, convenience is brought to operation, the use demand of a customer is met, and industrial popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of shrimp compound feed processing equipment, and in particular relates to a linkage control type crushing and screening machine for finished products. Background technique [0002] Prawns are a world-recognized high-protein aquatic product and are deeply loved by consumers. In the early days, my country's shrimp farming industry was mainly "Hong Kong breeding", that is, relying on natural seedlings with the tide, no feeding, no fertilization, it is completely an extensive farming method, the unit yield is low, and the yield per hectare is only tens of kilograms. [0003] At present, with the deepening of feed research, the technology of using prawn feed to improve production and quality is more and more widely used. Generally, the production process of prawn feed includes the following processes: raw material procurement - raw material crushing - batching measurement - mixing - granulation - crushing - fin...
