Abstract

A threshing device of a harvester comprises a main shaft, a bearing seat, a toothed nail, a reinforcing ring, a toothed nail fixing angle steel, an input port, an output port and an upper cover. The threshing device is characterized in that a threshing round disc is arranged on the main shaft by taking the main shaft as the center of the round disc; the threshing round disc is fixedly connected with the toothed nail fixing angle steel; and the threshing round disc has a distance of 440mm from the right end of the input port, and a distance of 80 to 110mm from the right end of the output port. The threshing device of the harvester is safe and reliable, and has the advantages of high stability and high threshing speed. In addition, the threshing device has the following advantages: the threshing device has high threshing efficiency and can handle about 1Mu wetter crops in one hour; the threshing device can handle crops with the length of 40cm, and has high throughput, which is higher than that of the prior at by more than 30%; and the threshing device has low threshing loss rate (smaller than 1.18%), which is superior to the national standard (1.2%).

Description

A kind of reaper thresher

Technical field

The present invention relates to a kind of farm machinery, be specifically related to a kind of small harvester sheller unit.

Background technology

Grain header, carry out threshing to it and handle like wheat or paddy etc. harvesting band stalk crops.When if the crops that will gather in are dry, when harvesting, just be prone to threshing, the threshing percent of loss is high, and the crops that will gather in are wet when getting into sheller unit, and it is incomplete to be not easy threshing or threshing again, also can increase the percent of loss of cereal; In actual production because when harvesting various factors influence, during harvesting crops neither too the nonwetting again situation of drying is less; So; Develop a kind of reaper thresher, when crops are dry, improve threshing efficiency, threshing is more complete when cereal is more moistening; Do not increase the weight of the sheller unit load again and influence device service life to solve the high problem of threshing percent of loss, this all has important social meaning and economic benefit concerning national and peasant household.

But there is the threshing poor effect in present reaper thresher more, and particularly when the said crops of treating the threshing processing were dry inadequately, the percentage of thresh was low; Some reaper thresher of the prior art is in order to strengthen threshing efficiency, handling capacity little (stalk that gets into sheller unit is less demanding in 30cm), and increased machine burden, the grain header life-span is shortened.

Summary of the invention

The object of the present invention is to provide a kind of reaper thresher that improves the grain threshing rate.

The objective of the invention is to realize like this: a kind of reaper thresher; Comprise main shaft, bearing block, finger, reinforcing ring, finger fixedly angle steel, charging aperture, discharging opening and loam cake; It is characterized in that: be that center of circle main shaft is provided with a threshing disk with the main shaft; Said threshing disk and said finger fixedly angle steel are fixedly connected, and said threshing disk is 440mm apart from the distance of charging aperture right-hand member, are 80～100mm apart from the distance of discharging opening right-hand member.

In order further to improve the threshing efficiency of above-mentioned reaper thresher; Above-mentioned loam cake inwall is provided with band iron; The band iron height is 20 ± 2mm, and band iron I goes up end distance loam cake left side 200 ± 2mm, following end distance loam cake left side 90 ± 2mm; Band iron II, band iron III and band iron IV are parallel to band iron I with interval 130 ± 2mm and are provided with, and band iron V and band iron IV are parallel to band iron I with interval 110 ± 2mm and are provided with.

Reaper thresher of the present invention, threshing speed is fast, and threshing efficiency is high, and handling capacity is big, the crops that can handle up the long 40cm of stalk, the threshing percent of loss is low, is superior to national standard 1.2% percent of loss; Load to grain header is little, when improving threshing efficiency and handling capacity, does not reduce the grain header life-span.

In order to improve the operating efficiency of above-mentioned reaper thresher; Dustproof and prevent that the sheller unit bearing from being twined grass to bearing; On the main shaft of the threshing cylinder two ends of above-mentioned reaper thresher, respectively be provided with 1 fixed disc, on the main shaft of cylinder two ends, respectively be provided with 1 spill disk with the main shaft activity that cooperates with said fixed disc, the one side of said spill disk cocked bead is set on the said fixed disc edge; Fixedly the angle steel welding is fixing for burnishing surface and finger; The spill disk diameter is slightly larger than fixed disc, and threshing cylinder is when operation, and the spill disk rotates with main shaft and can not rub with the fixed disc edge.

The diameter of above-mentioned spill disk than the big 0.5～4mm of diameter of fixed disc, is best with 1.5mm preferably.

Above-mentioned threshing disk fixedly preferably is connected through spot welding between the angle steel with above-mentioned finger.

The beneficial effect that the present invention has

Reaper thresher of the present invention, safe and reliable, good stability, threshing speed is fast, and threshing efficiency is high, and the operating efficiency of threshing is 1 mu of more moistening crops of threshing approximately per hour; Handling capacity is big, the crops that can handle up the long 40cm of stalk, and the throughput ratio prior art is high more than 30%; The threshing percent of loss is low, is lower than 1.18%, is superior to national standard 1.2% percent of loss.

Simultaneously, reaper thresher of the present invention also has the anti-effect that twines grass and good dustproof effect; After the loam cake of threshing cylinder built, loam cake and spill disk cooperated, the sealing threshing cylinder; Prevented that effectively the grass in the cylinder is wrapped between fixed disc and the bearing block support angle steel; Reduce the load of grain header, improved operating efficiency, continue to use grass and the dirt that need not to clear up on the bearing in 1 month; Prevented that also a large amount of dusts and dust in the cylinder from getting in the bearing block, increased the service life of grain header, sustainable use need not to keep in repair with getting into dust because twine grass in 4 years.
