Abstract
For the new cleaning plant of small-sized rice wheat combine harvester, including grain transfering tube, discharging opening, induced-draught fan, it is characterised in that：Also include a blanking suction channel, the blanking suction channel and grain transfering tube juxtaposition, the air inlet of the blanking suction channel is located at discharge outlet, and the grain transfering tube is connected with blanking suction channel at the air intake vent.A kind of embodiment is also to include several air registers on blanking suction channel.The present invention is simple and compact for structure, and production cost is low, and seed can obtain removal of impurities processing in two processes that convey and pocket, and impurities removing efficiency is up to more than 90%.
Description
Technical field
The present invention relates to rice wheat combine harvester, especially a kind of cleaning plant for rice wheat combine harvester.
Background technology
Cleaning plant is the important component of rice wheat combine harvester, and the quality of its performance directly affects the work of complete machine
Industry effect.Existing small-sized rice wheat combines the cleaning plant of united reaper, use air draught type removal of impurities principle, its primary structure shape more
Formula has two kinds：One kind is " conveying air draught ", is located at the confluence of threshing bin and grain transfering tube, seed by the inlet scoop of induced-draught fan
Removal of impurities processing is carried out in the course of conveying of grain transfering tube hoisting equipment；Another is " blanking air draught ", i.e., by the air draught of induced-draught fan
Mouth is located at the grain outlet (discharging opening of grain transfering tube tail end）, seed carries out removal of impurities processing during pocketing.Both structures
Impurities removing efficiency all can only achieve 50-70%.A kind of small-sized rice wheat combine harvester that can further improve and clean effect is needed in production
Cleaning plant occurs.
The content of the invention
The problem to be solved in the present invention is to provide a kind of new cleaning plant for small-sized rice wheat combine harvester.
The present invention is adopted the following technical scheme that：Including the interior grain transfering tube, discharging opening, induced-draught fan for setting hoisting equipment, the suction
Blower fan is provided with air intake vent and exhaust outlet, an in addition to blanking suction channel, the blanking suction channel and grain transfering tube juxtaposition, it is described fall
Expect that the air inlet of suction channel is located at discharge outlet, the grain transfering tube is connected with blanking suction channel at the air intake vent.It is former
Reason is：The present invention is combined two kinds of structure types of conveying air draught and blanking air draught are ingenious, and induced-draught fan passes through grain transfering tube and blanking suction
Air channel Liang Ge air channels air draught removal of impurities simultaneously, seed can obtain removal of impurities processing during former and later two for conveying and pocketing, and remove
Miscellaneous rate is up to more than 90%.
A kind of improve is also to include several air registers on blanking suction channel.Air register adjusting air inlet amount, is being protected
Cereal kernel can be avoided to lose in the case of barrier impurity-eliminating effect.
Another improvement is that the hoisting equipment is conveyer belt or conveying worm.
Advantage of the present invention：1st, simple and compact for structure, production cost is low.The present invention ties two kinds of conveying air draught and blanking air draught
The ingenious combination of configuration formula, it is that can be achieved to carry out simple modifications to casing, and production cost is low.2nd, impurity-eliminating effect is preferable.Induced-draught fan leads to
The air draught removal of impurities simultaneously of two air channels of grain transfering tube and blanking suction channel is crossed, seed can be obtained during conveying and pocketing former and later two
To removal of impurities processing, impurities removing efficiency is up to more than 90%.
Brief description of the drawings
Fig. 1 is an embodiment of the present invention anatomical structure（Housing parts）Schematic diagram.
Fig. 2 is the dimensional structure diagram of an embodiment of the present invention.
In figure：Hoisting equipment 1, grain transfering tube 2, discharging opening 3, induced-draught fan 4, air intake vent 5, exhaust outlet 6, blanking suction channel 7 is adjusted
Air door 8.
Embodiment
As shown in Figure 1 and Figure 2, an embodiment of the present invention includes the interior grain transfering tube 2, discharging opening 3, air draught for setting hoisting equipment 1
Machine 4, the induced-draught fan 4 is provided with air intake vent 5 and exhaust outlet 6, an in addition to blanking suction channel 7, the blanking suction channel 7 with it is defeated
The juxtaposition of grain pipe 2, the air inlet of the blanking suction channel 7 is at discharging opening 3, and the grain transfering tube 2 is with blanking suction channel 7 described
It is connected at air intake vent 5.As shown in figure 1, A is seed transport path；B is the air draught removal of impurities path of grain transfering tube 2；C inhales for blanking
The air draught removal of impurities path in air channel 7.Its principle is：The present invention is combined two kinds of structure types of conveying air draught and blanking air draught are ingenious,
Induced-draught fan by 7 two air channels of grain transfering tube 2 and blanking suction channel simultaneously air draught removal of impurities, seed convey and pocket former and later two
During can obtain removal of impurities processing, impurities removing efficiency is up to more than 90%.
A kind of improve is also to include several air registers 8 on blanking suction channel 7.The adjusting air inlet amount of air register 8,
Cereal kernel can be avoided to lose in the case of ensureing impurity-eliminating effect.
Another improvement is that the hoisting equipment 1 is conveyer belt or conveying worm.
The present invention is not limited to the concrete structure of above-described embodiment, and the equivalent transformation of other homogeneous structures each falls within the present invention
Protection domain within.
