Abstract

The utility model relates to a corn straw harvesting machine which comprises a machine frame, a conveyer and a harvester, wherein the harvester consists of a reduction gearbox, transmission chains, three knife shafts and cutting knives, the knife shafts include a left knife shaft, a middle knife shaft and a right knife shaft, the lower end of each knife shaft is fixedly connected with a group of cutting knives, one knife shaft is fixedly connected with the reduction gearbox, every two adjacent knife shafts are respectively connected through the transmission chains, the conveyer consists of three conveying chains, three chain wheels and a driving shaft, the chain wheels includes an upper chain wheel, a middle chain wheel and a lower chain wheel, the conveying chains comprise an upper conveying chain, a middle conveying chain and a lower conveying chain, reel paddles are arranged on the three conveying chains at certain intervals, one conveying chain is connected to the driving shaft and the knife shafts, and the other two conveying chains are respectively connected with the driving shaft and the two chain wheels. The corn straw harvesting machine has the advantages of simple structure, low cost, high work efficiency and low fault rate, is simple to operate, is applicable to corn straws with various line spaces, particularly narrow line spaces, the corn straws are regularly placed and paved after being cut, and have low cutting height and no dust shake, the corn straw harvesting machine can normally work under the condition of much weed, can not be blocked, and can also be used for harvesting lodged corn straws.

Description

The corn straw harvesting machine

Technical field

The utility model relates to the utility model and relates to a kind of agricultural cutter, especially a kind of corn straw harvesting machine.

Background technology

At present, China's reaping corn is to use manpower mostly, and inefficiency is wasted time and energy, and along with further developing of Tendency of Agricultural Machinery in Chinaization, various corn pickers occurred on the market now, but most of structure more complicated, cost is higher.

Summary of the invention

The utility model has designed a kind of simple in structure, and cost is low, and high efficiency is simple to operate, the corn stalk grain header that fault rate is low.

The technical solution of the utility model is: the corn straw harvesting machine, comprise frame, conveying plant and reaping apparatus, reaping apparatus is by reduction box, driving-chain, cutter shaft and cutter are formed, cutter shaft divides a left side, in, right three, the lower end of each cutter shaft is affixed one group of cutter respectively, affixed reduction box on one of them cutter shaft, connect by driving-chain between adjacent two cutter shafts, conveying plant is by carrier chain, sprocket wheel and driving shaft are formed, on sprocket wheel divides, in, following three, on carrier chain divides, in, following three, article three, be equipped with bat at regular intervals on the carrier chain, wherein a carrier chain is connected on driving shaft and the cutter shaft, the two other carrier chain is connected on driving shaft and two sprocket wheels, and cutter is made up of three cambered blades, the affixed guide of carving type on the frame, guide is positioned at the bottom righthand side of sprocket wheel, frame and tractor bumper junction affixed height location adjusting screw(rod).

Advantage of the present utility model is: simple in structure, cost is low, and high efficiency is simple to operate, fault rate is low, especially narrow row is apart from maize straw to be applicable to various line-spacings, and it is neat to cut the back lay, and it is low to cut stubble, do not beat soil, weeds for a long time also can operate as normal, does not stop up machine, can also gather in the maize straw of lodging.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Fig. 1 is the structural representation of an embodiment of the utility model;

Fig. 2 is the structural representation of the utility model embodiment cutter 9;
