Abstract
The invention relates to a component of a harvester, in particular to a secondary cleaning system for the harvester,. The system comprises a fan, an auger, a first air deflector, a second air deflector and a granary, wherein the granary is V-shaped, is fixedly connected to a bracket and is positioned right under a threshing cylinder; the auger is arranged on the lower part of the granary; and the first air deflector and the second air deflector present a disconnected V shape, are arranged between the threshing cylinder and the granary, and are almost parallel to the granary. The secondary cleaning system for the harvester is the thorough improvement of the traditional cleaning system, wherein a vibrating screen, a secondary horizontal auger, an inclined auger and the whole set of suction fan system are all unnecessary, the structure design is reasonable and simple, and the manufacturing and maintaining costs are lowered.
Description
Technical field
The present invention relates to a kind of grain header parts, be specifically related to a kind of grain header secondary cleaning and sorting system.
Background technology
The cleaning and sorting system of the combine on the existing market mainly is made up of vibratory sieve a, blower fan b, attraction fan c, secondary levels screw feeder, oblique screw feeder d etc., and above-mentioned cleaning and sorting system structure is very complicated, and manufacturing cost and maintenance cost are all higher.And, taken very big space because above-mentioned parts all are installed in below threshing cylinder and the Lysimachia sikokiana chain, make the threshing cylinder rising height of having to.The threshing cylinder height is put, and the threshing mode also just can only adopt general following threshing type at present, and promptly crop passes through from the cylinder below.And this kind threshing mode can be brought such as easy obstruction concave grate, vibratory sieve, and cereal is together discharged problems such as causing waste with foreign material.
Summary of the invention
Technical problem to be solved by this invention is: the invention provides a kind of simple in structure, clean respond well secondary cleaning and sorting system.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of grain header secondary cleaning and sorting system comprises fan, screw feeder, wherein, also comprises wind deflector one, wind deflector two, poly-granary.Described poly-granary is V-shaped, is fixedly connected on the support, and is under the threshing cylinder, and poly-granary bottom is provided with screw feeder.Described wind deflector one and wind deflector two are discrete V-arrangement, be between threshing cylinder and the poly-granary, and with poly-granary keeping parallelism roughly.The upper end of described wind deflector two and the corresponding end of poly-granary connect into a cylindrical storehouse, in the described cylindrical storehouse fan are installed.
Further technical scheme: the extended line of wind deflector one is crossed in the lower end of described wind deflector two, and the distance of the following end distance wind deflector two of wind deflector one is 20mm to 100mm.
Technical scheme further: the upper end of described wind deflector one and the corresponding end of poly-granary form an impurity discharging port.
Technical scheme further: the top of described wind deflector one upper end is equipped with an adjusting device, and described adjusting device is connected with the engine oil-valve operation bar by backguy.
The course of work of the present invention is: after the threshing of cereal process threshing cylinder, the process concave grate falls into the wind deflector one of below and the V shaped slab that wind deflector two forms, and continues past whereabouts.Falling in the process of poly-granary, grain falls under gravity into poly-granary, and other foreign material such as cane, shrivelled kernel, grass bits, dust etc. are subjected to the effect of wind-force, outside impurity discharging port discharge machine.Grain in the poly-granary is transported under the effect of screw feeder to grain header rear pack or further selected.
Beneficial effect of the present invention is: the present invention has done subversive reform to existing cleaning and sorting system, has saved vibratory sieve, secondary levels screw feeder, oblique screw feeder and induced-draught fan whole system.Reasonable in design, simple has reduced the cost of making and safeguarding, and makes full use of the space of grain header bottom, has reduced the height of threshing cylinder.If need be further selected, then only need install a small vibrating sieve additional and can obtain the lower cereal of impurity content.
