Description

A kind of module combined type multi-functional thrasher
Technical field
The present invention relates to the threshing apparatus with rotary workpiece, be specifically related to a kind of combined thresher technical field.
Background technology
Thresher is harvesting machinery, mainly refers to the harvest machinery of cereal crops, refers to the machinery that crop kernels can be separated with the stem stalk.Existing thresher function singleness, carry foreign material secretly more, and large to the loss of grain, crushing is high, is unfavorable for the raising of grain quality, and in use according to the difference of making the grain thing, the thresher kind of selecting is also different, as " rice thresher " is applicable to rice threshing, for being called of corn threshing " husker sheller " etc., same thresher can not carry out the threshing operation to multiple kinds of crops, as run into rice, wheat, corn, beans etc. need threshing simultaneously, existing simple function thresher is just helpless, peasant household will use rice-wheat thresher, husker sheller, at least three kinds of threshers such as bean threshing machine and typhoon cabinet, just can reach the work of various crops threshing and cleaning, this has increased the acquisition cost of equipment, operation and the maintenance program of these equipment also must be familiar with by peasant household, strengthened difficulty, and depositing of these equipment also needs to take larger place.
For making up the defect of existing thresher function singleness, some agricultural machinery are manufactured enterprise and have been developed relevant multi-functional separation instrumentation.
We know, during different crops threshing, integral-rack for thresher, drive disk assembly, requiring of screening removal of impurities parts etc. is basically identical, these parts can be general, but different crops are due to the difference at its fruit growth form and position, requirement for conveying parts and threshing unit has larger difference, the method that existing so-called multi-functional thrasher usually the adopts improvement of exactly conveying parts and threshing unit being compromised, add some auxiliary controlling organizations simultaneously, it can both substantially be completed when carrying out the different crops threshing, but in fact for any similar crop, the structure of this kind of thresher arranges all can not meet its threshing requirement fully, that is to say, the multi-functional thrasher of this type exactly belongs to the product that a kind of various functions is compromised and compromised, its pursuit be a kind of integral body, the performance that substantially can meet the demands, but its Threshing for similar crop is not outstanding.
For example " multi-functional thrasher 02245767 ", it discloses a kind of multi-functional thrasher, should be in order to guarantee various kidney beans, soybean, the multiple kinds of crops such as wheat are carried out threshing, be provided with vertical, horizontal adjustment hydraulic jack and adjusting screw are realized multiple method for changing speed, there is very high automated job degree, can find out, this equipment is in order to realize the multi-functional purpose to beans and wheat threshing, abandoned the structure for similar crop Threshing the best, the settings such as speed, increased multiple auxiliary part, not only can't realize best Threshing, increased the complexity of equipment simultaneously, the manufacturing cost of equipment and the expense of maintenance have also just been increased.
Also have; existing thresher automaticity is not high; the too much participation that depends on manpower; during as existing rice-wheat thresher work; just need to carry out threshing repeatedly with manually hauling wheat putting in the machine the inside, operating personnel's labour intensity is too large; and threshing efficiency is also very low, is unfavorable for improving agricultural productive force.
