Abstract
The utility model relates to an axial-flow threshing mechanism for a small rice harvester. In the utility model, a spiral spikes conveying device and a threshing cylinder are integrally arranged on a same main shaft; crops striking teeth are ranged on the threshing cylinder according to the contrail of a helical line, and the crops striking teeth and the cross section of the threshing cylinder form an inclined angle theta which ranges from 1 to 5 DEG; the end of the crops striking teeth is provided with a bend, and a bending segment and the axial line of the crops striking teeth form an inclined angle beta which ranges from 1 to 15 DEG. The utility model has the advantages of simple structure, easy fabrication and process, small volume, the integration of conveying spikes and threshing, the effective shortening of processing route, the reduction of motive power consumption, and high thoroughness of threshing. The axial-flow threshing mechanism for a small rice harvester is suitable for being used as a spikes conveying and threshing device on a small rice harvester.
Description
The utility model is a kind of small-sized rice grain header axial flow threshing mechanism.
Large-scale rice combine; obtained widely applying in northern China; this mainly is because northern landforms shape is suitable for using large-scale combine; and southern rural area; because the knob is many; monolithic field soil area is less; be unsuitable for using large-scale combine, though agricultural machinery scientific research department has released the type that is suitable for southern rural area paddy rice harvesting substantially through development for many years; but still existing the some shortcomings part aspect several key technologies; as: separating mechanism, owing to due to the structural design, make threshing performance not high; grain residues amount is more on the spike of rice, causes waste.
The purpose of this utility model is to overcome the deficiency of prior art and a kind of compact conformation, convenient processing and manufacture is provided, and integrates and send fringe and threshing operation, threshing performance height, the small-sized rice grain header axial flow threshing mechanism that power consumption is low.
The utility model is to adopt art scheme realization down: it is installed on spiral stachys-feeding device and threshing cylinder consubstantiality on the same main shaft, grain patting teeth is arranged on the threshing cylinder by spiral trajectory, be 1-5 ° of inclination angle [theta] with the threshing cylinder cross section, and the grain patting teeth end is provided with a bending, and bending segment and grain patting teeth axis are 1-15 ° of angle of inclination beta.
The utility model is simple in structure, convenient processing and manufacture, volume are little, integrate and send fringe, threshing, has effectively shortened processing route, has reduced power consumption, and the threshing performance height is suitable for as sending fringe on the small-sized rice grain header, and sheller unit is used.
Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is that the A of accompanying drawing 1 is to view.
See accompanying drawing 1,2, the utility model is made up of spiral stachys-feeding device 1, threshing cylinder 2, grain patting teeth 3, main shaft 4, described spiral stachys-feeding device 1, threshing cylinder 2 disjunctors are installed on the main shaft 4, grain patting teeth 3 line tracking in the shape of a spiral is distributed on the threshing cylinder 2, and be 1-5 ° of inclination angle [theta] with the cross section of threshing cylinder 2, grain patting teeth 3 ends are provided with a bending segment, and its bending segment and grain patting teeth 3 axis are 1-15 ° of angle of inclination beta.
Operation principle of the present utility model is sketched in down: when the standing grain fringe be cut off send into the utility model after, spiral stachys-feeding device is sent the standing grain fringe into the threshing cylinder place in the utility model, grain patting teeth on the threshing cylinder smashes the standing grain fringe, and broken standing grain fringe is promoted forward along helical track, meanwhile, grain and extremely broken standing grain fringe will enter in the bucket by the screen cloth of being located at the threshing cylinder below, and unnecessary standing grain fringe will be discharged by ear outlet.The utility model makes and takes off rate efficient height owing to adopt said structure, the threshing performance height, and volume is small and exquisite, and compactness is particularly suitable for using on the small-sized rice grain header.
In sum, the utility model is simple and reasonable, convenient processing and manufacture, and volume is little, and threshing is effective, and the threshing performance height is suitable for the use on the small-sized rice grain header.
