Description

A kind of novel straw cutting machine

Technical field

The utility model relates to the hay cutter tool, particularly long stalk forage cutting machine tool.

Background technology

At present domestic hay cutter commonly used generally is made up of dish out mechanism, gear, transmission mechanism, safety device etc. of intake mechanism, chopping, intake mechanism comprises delivery chute, running roller up and down, shredding the mechanism of dishing out comprises main shaft, knife rest, knife section, ledger-plate, goes up lower casing and material casting mouth, transmission mechanism comprises V-belt, belt pulley, travelling gear, power transmission shaft, gear-box etc., and safety device comprises belt pulley protective cover, gear protective cover, feeding protective cover, cover etc. up and down.During work, forage is input to feeding roller by carrier chain, reaches hand hay cutter and cuts the position, is cooperated with ledger-plate the forage chopping by the knife section on the rotary head, and the air-flow that is produced by the fan blade type knife rest joint material that will shred is thrown and delivered to certain height and apart from stacking, storage again.This machinery is generally made mating power with motor, and feedstock direction is vertical storing with the chopper direction of rotation, and carrier chain adopts iron plate formula chain strips.Though this type of machinery compact conformation is sturdy and durable, be convenient to haul, the hand hay cutter that can be used in feeds such as fresh and dried weeds, straw, wheat straw, beanstalk, corn stalk is cut, but owing to be subjected to cutting up with a hay cutter the limitation of cutting with feeding structure and transfer efficiency, the cutterhead rotating speed is low, and production efficiency is difficult to improve.The 93ZP-8000 type hay cutter of producing with Shandong Province Feicheng Wutao Agricultural Machinery Building Material Machinery Factory is an example, mating power 15KW motor, deadweight 1000kg, cutterhead rotating speed 600r/min, production efficiency 2～8t/h.If in the heavy 4000kg of every mu of straw, then every hay cutter per hour can only cut up with a hay cutter 2 mu of stalks, obviously be used for the large tracts of land operation of returning crop stocks to the field and adapt to inadequately, cost is also higher simultaneously.

Summary of the invention

The purpose of this utility model just provides a kind of novel wheat straw, stalk cutting machine tool, improves feeding mechanism, improve to carry working (machining) efficiency, can be used to process fresh and dried feed, can be used for the land for growing field crops operation of returning crop stocks to the field again, reduce cost, guarantee safety, enhance productivity.
