Large-scale square banding machine

Abstract

The invention provides a large-scale square banding machine. A compression chamber is internally provided with a compression plunger piston and a compression baffle which are driven by a hydraulic cylinder, a pre-compression chamber communicated with a compression chamber discharging port is arranged above the compression chamber, the pre-compression chamber is internally provided with two compression rollers driven by a hydraulic motor, a controller is combined with a hydraulic system, motion state signals are collected through various stroke switches and sensors, after the controller processes the motion state signals, a hydraulic system component is controlled to drive the compression plunger piston and the compression rollers to achieve the automatic control of banding machine compression. Compared with the compression method of a traditional large-scale square banding machine, the feeding mode is changed, and the soil content in bundled straw is reduced; the pre-compression chamber is added on the basis of an existing machine type to achieve the pre-compression deformation of the straw, thereby providing convenience for final compression forming; an electro-hydraulic automaticcontrol system replaces manual operation, thereby saving the labor, reducing the labor cost, improving the work efficiency, improving the working environment, and being capable of controlling, monitoring, alarming, and urgently stopping a machine in real time.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a large square baler. Background technique [0002] Straw is an important part of biomass energy, easy to burn, and has zero carbon dioxide emissions when burned. my country is a large agricultural country. Although the amount of straw in agricultural production is huge every year, due to the difficulty of collecting and storing, the uncommon application of balers and the low automation productivity, the storage and utilization of straw in my country are low, and the phenomenon of burning is serious, which is not conducive to ecology. Agricultural construction. [0003] my country began to study balers in the 1970s. There are two types of round balers that use intermittent baling and are suitable for small plots, and square balers that can work continuously and are suitable for harvesting large and medium-sized farms. The research on square balers is mainly focused on small and...
