Abstract

The utility model relates to a cotton stalk harvester, belonging to the technical field of cotton stalk harvesting machine, which comprises a frame, wherein the bottom of the frame is transversely provided with a cutter shaft; the surface of the cutter shaft is circumferentially distributed with tool holders uniformly; the tool holders are fixed with cutter blades; the top of the frame is provided with a trailer connected with the traction device of a tractor; the frame is fixed with an input shaft connected with a speed reducer for the output power of the tractor. The cotton stalk harvester is characterized in that the cutter shaft has two shafts arranged on one straight line; the speed reducer is arranged at the middle part of the frame, having left and right outputs, while two output shafts respectively drive one cutter shaft; the two-drive structure and the two cutter shafts can reduce the cutting length in soil of the cutter blades when the harvester harvests multiple rows of stalks, to reduce the resistance of soil on the cutter blades, reduce power consumption, improve production efficiency, obtain symmetric structure of the whole harvester, set gravity center at middle part, make cutting depths of the cutter blades uniform, improve harvesting quality and prolong service life of the harvester.

Description

A kind of cotton stalk reaping machine

Technical field

The utility model relates to a kind of cotton stalk reaping machine, platymiscium stalk harvest machinery technical field.

Background technology

Traditional cotton stalk harvesting method be manually by apparatus utilize lever principle with cotton straw by pulling up, inefficiency, the effort of taking a lot of work, increase and the large-area plantation of farmization along with Cotton in China plantation amount, traditional stalk harvesting method far can not adapt to production requirement, multi-form cotton stalk harvest machinery arises at the historic moment, comprise clamp, pair roller, dish saw hinge is pulled out, forms such as cutter shaft, wherein, the production efficiency of rotary cutting shaft type cotton-stalk harvester is higher, can gather in the cotton stalk of multirow simultaneously, but existing rotary cutting shaft type cotton-stalk harvester is single-shaft configuration, is 02235470.0 utility model as number of patent application, for adapting to the cotton field requirement of different spacings, its roll blade is rectangular structure, and this type needs certain soil penetraction depth when gathering in the crops, when cutter shaft length is big, the resistance that roll blade is subjected to soil is very big, and power consumption is big, has restricted production efficiency simultaneously.

The utility model content

The utility model technical issues that need to address provide a kind of cotton stalk reaping machine, by architecture advances to existing hob type cotton-stalk harvester, improve the equipment symmetry, make blade even to soil incision power, the resistance of soil blade when reducing to gather in the crops reduces power consumption.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:

A kind of cotton stalk reaping machine, comprise in its structure: frame, the setting of frame bottom transverse is supported on the cutter shaft on the frame, the circumferential uniform knife rest in cutter shaft surface, fixing roll blade on the knife rest, frame top is provided with and connects pulling of tractor-drawn device, be fixed with the decelerator that power shaft connects tractor dynamic power output on the frame, described cutter shaft is the cross-compound arrangement that is arranged on the same straight line, decelerator is arranged on the frame meta, its output form is a left and right sides dual output, and two output shafts respectively drive a cutter shaft.

Further improvement in the technical proposal of the present utility model is: be connected by chain or belt between reducer output shaft and the cutter shaft, or directly connected by shaft joint.

Chain or belt are arranged on the inboard or the outside of cutter shaft, when chain or belt are arranged on the outside of cutter shaft, are connected by jackshaft between the driving wheel of chain or belt and the reducer output shaft.

3 rows, 4 row or 5 gang feed tool racks are set on the cutter shaft.

Because the technological progress of having adopted technique scheme, the utility model to obtain is:

The utility model is owing to adopt two the driving and two roller cutter shaft structure, be provided with distance between two cutter shafts less than the cotton field line space, the soil of roller blade incision length in the time of can reducing to gather in the multirow stalk, reduce the resistance of soil pair roller blade, reduce power consumption, enhance productivity, simultaneously because its pair drives, the employing of cross-compound arrangement, the reaping machine overall structure is symmetrical arranged, and center of gravity is placed in the middle, and roll blade is even to the incision power of soil, the depth of cut unanimity, results quality height, transmission and pull the stability under loading of mechanism, evenly, equipment is not fragile.
