Abstract
The utility model discloses a three-roller automatic clamping rice thresher, which comprises a machine frame, three threshing rollers, a clamping conveying mechanism, a cleaning sieve, a blower, a raiser, a cleaning impurity removing device and a transmission part, wherein a main frame shaft and the blower are cut off and are divided into two, and the diameter of an original blower can be increased; thus, wind power of the blower is increased and the grain cleaning rate is improved. The cleaning sieve is widened, the area of a sieve body is increased so as to enable bottom wind to easily pass through between granules, and thus, impurities of mixed leaves and the kinds of bran are driven so as to enable air draft to be more ideal. A grain cleaning blower is arranged between a discharge hole of the impurity removing cleaning device of the raiser and a grain collecting bucket, and small mixed leaves and chaff existing in the process of grain cleanness of a second time are blown awan so as to further improve the grain cleaning rate. The original chain transmission between a worm gear box hung at one side and a clamping gear is improved into an output shaft of the worm gear box by the transmission part through the process that the clamping gear is driven by a cardan joint. The utility model has the advantages of good balance degree, good concentricity, without skid, without rotation loss, low failure rate, simpleness, convenience and high durability.
Description
Technical field
The utility model relates to a kind of thresher machine, is specifically related to a kind of paddy-eliminator.
Background technology
At present; the paddy-eliminator type is more; the ubiquity selection by winnowing is unclean; it is many to have impurity; threshing performance and the low problem of clean rate; the patent No. that the applicant applied in 2002 is 02211211.1 " the automatic clamping paddy-eliminator of three rollers "; three threshing roller tubes are set; paddy rice threshing performance and clean rate have been improved; the applicant's number of applying for a patent again is 2003201111467.0 " thresher that has the removal of impurities cleaning plant "; can further remove the short cane of grain of rice tail end, reduce the paddy rice percentage of impurity.Hang and former threshing running part worm gear is other, drive the clamping belt wheel with driving-chain, chain is killed sometimes, and difficult dress just makes the machine easy break-down.
The utility model content
The purpose of this utility model is to provide a kind of stable transmission three rollers automatic clamping paddy-eliminator, is the further improvement to above-mentioned two kinds of threshers, improves paddy rice threshing performance and clean rate more efficiently, meets or exceeds clean grain standard.
The automatic clamping paddy-eliminator of the utility model three roller comprises frame, three threshings rollers tube, clamping conveying mechanism, sorting screen, blower fan, lifters, cleans knot screen and running part, the boss rod and the main air arbor of described threshing roller tube disconnect, and take turns transmission by two strands between the diaxon; Between the discharging opening of the removal of impurities cleaning plant of described lifter and the collection grain bucket clean grain blower fan is set; Described running part, spindle end at lower cylinder is provided with three belt pulleys, a belt pulley links to each other with the main speed reduction box belt pulley, a belt pulley links to each other with the belt pulley of sorting screen gear-box, belt pulley on the power shaft of another belt pulley and worm gear case links to each other, and the output shaft of worm gear case drives the clamping wheel by universal joint.Described sorting screen width increases to 700-800cm.
The utility model three automatic clamping paddy-eliminator boss rods of roller and blower fan disconnect, and are divided into two, blower fan axle whereabouts 140mm under the situation that increases former blower fan diameter, can not gone out careless platform constraints again, thereby increase blower fan wind-force, improve clean grain rate.Sorting screen is widened to 700-800cm, increases the sieve nest area, thereby paddy rice is tiled on the sieve nest thinly, and end wind easily passes through between the particle, thereby drives the impurity of assorted leaf, chaff class, makes air draught better.In the middle of collection grain bucket, clean grain blower fan is set at lifter, can little assorted leaf, the illiteracy chaff that the clean grain of secondary also exists be blown away, further improve clean grain rate.The utility model running part drives the clamping wheel with the output shaft that former other worm gear case of hanging and chain drive between the clamping wheel are improved to worm gear case by universal joint, makes the degree of balance good, and good concentricity is non-slip, do not throw switch, and the minimizing fault rate is easy to be durable.
