Description

Soybean combine

Technical field

The utility model belongs to agricultural machinery technological field, is specifically related to a kind of soybean combine.

Background technology

Domestic existing combine, particularly middle-size and small-size backpack soybean combine, the cutting part of the ceding of Taiwan is generally taked rigid the connection with the ceding of Taiwan.Exist the problem of close mowing and profiling performance deficiency, the applicant improved this part in 1998, and had applied for patent, and the patent No. is 98250707.0, and this improvement has solved ground, level land close mowing profiling problem.But still can not meet the demands on the casual hillock of hilly ground or casual river, be uneven greatly or suddenly, then more be difficult to realize the close mowing profiling as the ridge shape gradient.Existing grain header is dialled the standing grain device and is prone to beanstalk and twines problem on it, divide grain lifter work undesirable, exist to lose and leak the beanstalk phenomenon, beans often appears in the sieve nest that is arranged on after the threshing below the cylinder notch board, assorted complementary set heap and clogging have influenced activity duration and operation quality.

The utility model content

The purpose of this utility model is to provide that a kind of profiling close mowing is effective, beanstalk cuttting cleaning rate height, soybean combine that threshing performance is high.

For achieving the above object, the utility model soybean combine is by the header assembly, beans standing grain conveying plant and thresher assembly are formed, straw shift wheel is installed on the frame of header assembly front upper place by axle and bearing, ceding of Taiwan front end is installed cutting and copying device, divide grain lifter to be separately positioned on the frame of both sides, ceding of Taiwan assembly the place ahead, beans standing grain conveying plant front end is connected with the header afterbody, the rear end is connected with the thresher assembly, the header assembly is arranged on the tractor forebay, the thresher assembly is fixed on the frame of tractor back, it is characterized in that: a universal land wheel of profiling respectively is installed in the front end both sides of header frame; Be provided with on straw shift wheel and prevent the beanstalk wind, the branch that is provided with in header front end both sides installs a component grain lifter additional in the middle of holding up device at least; The one sieve assembly of walking about is set in the thresher assembly.

Described on straw shift wheel, install prevent the beanstalk wind, make by cambered plate, an end is packed in by U-shaped card silk on the fixedly iron pipe of bullet chi of straw shift wheel, the other end is screwed onto and plays on the chi.

The described sieve assembly of walking about is made up of driving wheel, follower, eccentric wheel, driving-chain and bar formula sieve sheet, driving wheel, follower, eccentric wheel are by axle and bearing supporting, the driving-chain activity installs around in driving wheel, follower, eccentric wheel periphery, on the bar formula sieve sheet some sieve apertures are set, bar formula sieve sheet is hinged on the driving-chain.

The advantage of the utility model soybean combine:

1, at the header frame front end the universal land wheel of profiling is installed, when landform or ridge shape change suddenly, the ceding of Taiwan is risen and fallen with landform, cooperate with the close mowing copying device to make profiling close mowing effect better, solved the profiling close mowing problem of all kinds of landform, ridge shape.

2, setting prevents the beanstalk wind on straw shift wheel, this device is arc thin plate, the bullet chi that one end is packed in straw shift wheel by U-shaped card silk is fixedly on the iron pipe, the other end is screwed onto and plays on the chi, ceding of Taiwan direction can make the beanstalk that cuts away directly enter ceding of Taiwan rear and enter beans standing grain conveying plant, avoids being wrapped on the straw shift wheel.

3, the branch that is provided with in header front end both sides installs a component grain lifter additional in the middle of holding up device at least, and this branch is held up device the beanstalk of the lodging of centre can be propped up separately to send into the ceding of Taiwan and advanced cutting, can reduce the leakage of beanstalk and cut rate.

4, the walk about bar formula sieve sheet of sieve is hingedly mounted on the driving-chain, bar formula sieve sheet under eccentric transmission in the past backward beat type walk about, walk about sieve to the beans of taking off and the surplus screening of walking about of mixing, below bar formula sieve sheet forwards the sieve of walking about to, the sieve sheet is sagging along bearing pin, walks about and sieves not Ji Dui, do not stop up.
