Abstract
The utility model relates to a threshing device for combine harvesters, which comprises rack bar threshing cylinders arranged at the upper part of a threshing chamber, top covers of a spiral guide grass plate arranged at the bottom surfaces of the rack bar threshing cylinders, a concave plate sieve, a vibration sieve, a blower and an auger all arranged at the lower parts of the rack bar threshing cylinders. The utility model is characterized in that the front and the rear rack bar threshing cylinders are parallelly and horizontally arranged at the upper part of the threshing chamber; the top covers which are opposite to the spiral direction of the spiral guide grass plate at the bottom surfaces are respectively covered at the rack bar threshing cylinders. The utility model uses double cylinders with different rotary speeds to thresh, which effectively solves the conflict that the combine harvester is difficult to compromise the threshing thoroughness and the shell damage rate in harvesting for a long time. The practice proves that the thoroughness threshing rate of paddy rice in harvesting reaches by 99.9 percents and the shell damage rate is within 1 percent.
Description
Technical field
The utility model relates to the mechanical threshing device of combine, especially is suitable for the mechanical threshing device of cereal.
Background technology
The grain threshing device of existing all feeding-in combine includes threshing cylinder with teeth and concave grate etc.During the cylinder high speed rotating, its spike-tooth constantly impacts the rice bar that is fed, and enters concave grate thereby the grain of mature and plump is split away off from the rice bar soon, but some not very the grain of mature and plump then difficult drop-off get off, and dumped waste with straw.If will improve the paddy threshing performance, need improve the rotating speed of cylinder, also promptly improve the intensity that impacts of its spike-tooth, impact intensity yet improved, can increase the shell-breaking rate of mature and plump grain greatly.General provision, paddy harvesting threshing shell-breaking rate should not surpass 2%, otherwise will have a strong impact on the storage and the seed germination rate of paddy.
Summary of the invention
The technical problem that the utility model quasi-solution is determined is to provide a kind of threshing performance height shell-breaking rate low efficient grain threshing device for combine.
The technical scheme that addresses the above problem is: it comprises the top cover that the ratch threshing cylinder that is installed on threshing chamber top and bottom surface thereof are provided with the spiral grass guide board, be positioned at concave grate, vibratory sieve, blower fan and the auger of ratch threshing cylinder below, the invention main points are, be horizontally installed with two the ratch threshing cylinders in front and back on threshing chamber top side by side, and on 2 ratch threshing cylinders, distinguish the opposite top cover of the hand of spiral of the spiral grass guide board of its bottom surface of cover cap.And after the preferred design rotating speed of ratch threshing cylinder greater than the rotating speed of preceding ratch threshing cylinder.
Outstanding effect of the present utility model is: combine is when work, the rice bar is the lower preceding ratch threshing cylinder of feeding rotating speed earlier, the caducous grain of mature and plump is split away off fast, the rice bar that does not purify as yet then enters back ratch threshing cylinder again, make on the rice bar remaining than difficult drop-off not very the grain of mature and plump under the more powerful strike of higher speed swing roller, separate, thereby solved this contradiction that harvesting threshing performance that combine for a long time exists and shell-breaking rate can not finely not taken into account effectively.Facts have proved that paddy rice harvesting threshing performance of the present utility model reaches 99.9%, and shell-breaking rate only is below 1%.

Embodiment
Dressing mechanism among the embodiment, this device is identical with existing apparatus basically, promptly is made up of the vibratory sieve 11 that is installed on threshing chamber 14 middle and lower parts, auger 12, preceding blower fan 13 and rear fan 10; Then be horizontally installed with two preceding ratch threshing cylinder 2 and back ratch threshing cylinders 6 (also the diameter of preceding ratch threshing cylinder 2 can be done greatly slightly) that size is identical with structure side by side on threshing chamber 14 tops, the top of two cylinders cover cap respectively its lower arcuate surface to be provided with the hand of spiral of spiral grass guide board 20 of top cover 1,5, two top covers 1,5 of spiral grass guide board 20 then opposite; The following concave grate 4,8 that surrounds respectively of two cylinders; Preceding ratch cylinder shaft 3 is connected with bigger belt pulley 18, back ratch cylinder shaft 7 is connected with less belt pulley 16, be connected with motive power driving belt 19 on the belt pulley 18, belt pulley 18 also is connected with driving belt 17 with belt pulley 16 simultaneously, therefore, the rotating speed of preceding ratch threshing cylinder 2 is less than back ratch threshing cylinder 6.During combine work, earlier the rice bar is cut off, then from preceding ratch threshing cylinder 2 leading sections of threshing chamber import 15 feedings, under the guiding of the spiral grass guide board 20 of pretectum 1, come off after the mature and plump grain the rice bar in the past ratch threshing cylinder 2 afterbodys discharge, enter the higher back ratch threshing cylinder 6 of rotating speed, under powerful ratch effect, purify remaining not fuller grain on the rice bar, the straw that purifies grain is at last discharged from back roll afterbody, threshing chamber outlet 9 under the guiding of spiral grass guide board; And enter concave grate 4,8 respectively earlier from the grain that two cylinders are taken off, again through vibratory sieve 11, after front and back blower fan 13,10 is cleaned, by auger 12 output packings.
Claims (3)
1, a kind of sheller unit of combine, comprise the top cover that the ratch threshing cylinder that is installed on threshing chamber top and bottom surface thereof are provided with the spiral grass guide board, be positioned at concave grate, vibratory sieve, blower fan and the auger of ratch threshing cylinder below, two ratch threshing cylinders (2), (6) before and after it is characterized in that on threshing chamber (14) top side by side, being horizontally installed with, and go up opposite top cover (1), (5) of the hand of spiral of the spiral grass guide board (20) of its bottom surface of cover cap respectively in two ratch threshing cylinders (2), (6).
2,, it is characterized in that the rotating speed of the rotating speed of back ratch threshing cylinder (6) greater than preceding ratch threshing cylinder (2) by the sheller unit of the described combine of claim 1.
3, by the sheller unit of the described combine of claim 1, two ratch threshing cylinders (2), (6) before and after it is characterized in that, its size is identical with structure, or the diameter of preceding ratch threshing cylinder (2) is big slightly.
