Automatic straw material feeding device of ring die briquetting machine

Abstract

The invention belongs to the field of agricultural machines, and particularly relates to an automatic straw material feeding device of a ring die briquetting machine. The automatic straw material feeding device comprises a feeding device, a material conveying device and a control module. The control module comprises a PLC, a motor driver, a weighing sensor and a motor switch. Mass-shaped materials are grasped into a material storage box through a grass grasping machine, and the materials are dispersed by two spiked shafts in the upper part of the material storage box and then evenly fall on a large screw rod. The large screw rod outputs the materials uniformly through a guide hopper, and the materials fall on a conveying belt of the material conveying device and then are fed into the ring die briquetting machine. The weighing sensor below the material guide hopper transmits information to the PLC in real time, the PLC sends out pulses to the motor driver to perform feedback control of the rotating speed of a large screw rod motor, and therefore the stable feeding amount of straw is ensured. The automatic straw material feeding device is simple in structure and convenient to operate, the feeding end is intelligently controlled, feeding labor of two to three persons is saved, the problems that straw feeding is unstable in a straw briquetting production line and blocking frequently happens are solved, and therefore the straw briquetting quality and the production efficiency are improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and more specifically relates to a PLC-controlled automatic feeding device for straw materials of a ring die briquetting machine. Background technique [0002] my country is a large agricultural country, with large output, wide distribution and many varieties of crop straw. It has long been a valuable resource for farmers' life and agricultural development. However, regarding the utilization of straw, returning the full amount of straw to the field will affect the sowing and growth of crops, and the burning of straw will pollute the atmosphere. Therefore, it is necessary to effectively and comprehensively utilize straw and turn waste into treasure. [0003] With the development of ring die extrusion molding technology, a large amount of straw in my country has also been better comprehensively utilized. For example, straw extrusion into blocks can be used as biomass fuel, and it is also more...
