Abstract
The utility model discloses a threshing cylinder of a full-feeding combine harvester. The threshing cylinder comprises a threshing cylinder shaft, an amplitude disc and three to six threshing tooth rods, wherein the tooth rods are symmetrically connected with the amplitude disc and uniformly distributed along the circumference; a plurality of short rasp bars are welded at the front 3/4 or 4/5 sections of the tooth rods; threaded holes are formed at the middle parts of two side surfaces of each short rasp bar; the threaded holes can be used for installing plate teeth; round holes are formed at the lower parts of the two side surfaces of each short rasp bar, so that tooth rods can penetrate into the round holes to be welded conveniently; the tops of the plate teeth which can be selectively installed on the two side surfaces or a single side surface of each short rasp bar are 6-12mm higher than the top parts of the short rasp bars; a lower part semicircular groove spans on the tooth rods 3 and is used for preventing the tooth rods 3 from rotating after being stressed. Two to four spike teeth are further welded at the rear end of each threshing tooth rod. Due to the number and the position of the plate teeth installed on the side surfaces of the short rasp bars, the purposes of harvesting rice, wheat, rape and soybean, without generating a great quantity of crushed straw and smashing the grains are achieved.
Description
Technical field
The utility model relates to a kind of threshing cylinder of all feeding-in combine.
Background technology
Crawler self-propelled combine harvester is mainly used in gathering in paddy rice, wheat, the structure of its threshing cylinder is designed to two kinds of open type (being common in all feeding-in combine) or encloseds (being common in half feed combine harvester) by being incorporated as thing characteristics usually, and the open type threshing cylinder by the threshing element structure divide that spiketooth type, plate are tooth-like, bow tooth formula or rasp bar formula.Spike-tooth or plate tooth-like main by " strike " with the crop threshing, often be used to threshing paddy rice or wheat, but can produce a large amount of crushing straws and increase cleaning load; The rasp bar formula mainly leans on " rubbing " with the crop threshing, because the curved surface of oblique burr is arranged on its working surface, advantage is that the little crushing straw of hitting power is few, relatively is fit to threshing wheat and rape, shortcoming is unsuitable threshing paddy rice, if the dehydration rice easily rubs into paddy rice and unfavorable storage or seed sprouting.Yet, the peasant not only will receive paddy rice, wheat for " a tractor serves several purposes ", often also attempt being used for harvesting rape or soybean, but effect is all undesirable, mainly be that the single threshing tooth structure of above-mentioned threshing cylinder is when harvesting rape or soybean, overbreak that ratch or plate toothing can be beaten stalk impact is cleaned, and the rasp bar structure can be rubbed paddy with the hands broken generation and cracked rice in a large number.Jiangsu University had once designed a kind of tangential feeding type axial drum of taking into account harvesting paddy rice, wheat, rape, soybean according to advanced foreign technology in 2006, the patent No.: CN200610038924.6, but we still feel not ideal enough after analyzing.Reason is that 1. these cylinders are closed type structure, is very easy to when receiving moist crop stop up; 2. the Lysimachia sikokiana function of cylinder back segment is not strong, and namely Lysimachia sikokiana is not smooth; 3. taking off Different Crop, need to change different patterns under short and plate tooth namely very loaded down with trivial details and change easily mistake.In a word, this structure cylinder be used for theoretical research can, but impracticable.
Summary of the invention
The purpose of this utility model provides and a kind ofly can gather in paddy rice, wheat, not only can harvesting rape, soybean and but also can not produce the multifunctional assembled full-open type threshing cylinder of a large amount of crushing straws or seed damage.
Technical solution of the present utility model is: comprise the drum shaft, width of cloth dish, the threshing toothed bar that are installed on all feeding-in combine threshing cylinder, threshing cylinder is the full-open type ratch cylinder that 3 to 6 rooted tooth bars are installed, and 3 to 6 rooted tooth bars are symmetrical, uniform with being connected along circumference of width of cloth dish; Every threshing toothed bar is gone forward 3/4 or 4/5 section to be welded with some sections patterns under short and is used for rubbing; The two sides of every section patterns under short become an inclination angle perpendicular to ratch axle center or the vertical another side of one side with the ratch axis; All there is a screwed hole at middle part, patterns under short two sides, can be used for the plate tooth that increases hitting power is installed, and a circular hole is respectively arranged at bottom, patterns under short two sides, is through first on the ratch before the welding; There is a through hole at the plate tooth middle part that is installed in the patterns under short side, and a half slot is arranged at the bottom; The plate crown exceeds 6～12 millimeters than patterns under short top after installing; 2～4 finger-like teeth that every threshing toothed bar rear end is welded with or lamellar tooth are used for discharging the long stalk that has purified.
The beneficial effects of the utility model are: along all being welded with patterns under short, spike-tooth on every rooted tooth bar of circumference symmetry, uniform installation, some plate teeth higher than patterns under short that can install or remove in the side of patterns under short as required again, thus integrate during threshing rub, strike, Lysimachia sikokiana function.When the dehydration rice, the installing plate tooth namely increases hitting power, and hitting power is larger more at most for the plate tooth of installation; When de-oiling dish, wheat, soya bean, part installing plate tooth or not the installing plate tooth namely reduce the hitting power increase and rub power, but rub a little less than the pure threshing cylinder with rib of force rate, that is to say that quantity by the installing plate tooth and position can reach can gather in paddy rice, wheat, again can harvesting rape, soybean and the purpose that also can not produce a large amount of crushing straws and rub broken seed with the hands.

Embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Embodiment, see Fig. 1,2,3, full threshing drum feed comprises drum shaft 1, width of cloth dish 2,3 to 6 threshing toothed bars 3,3 to 6 ratch 3 are symmetrical, uniform with being connected along circumference of width of cloth dish 2, front 3/4 or 4/5 section of ratch 3 is welded with some sections patterns under short 4, patterns under short 4 two sides or single side face can be selected installing plate tooth 5,2～4 spike-tooths that the rear end of every threshing toothed bar 3 is welded with (being finger-like tooth or lamellar tooth) 6.
All there are a through hole or screwed hole in middle part, described patterns under short 4 two sides, can be used for installing plate tooth 5, and a circular hole is arranged at the bottom, is used for being through ratch 3.
After described plate tooth 5 was installed in patterns under short 2 sides, the plate crown exceeded 6～12 millimeters than patterns under short top, and the bottom half slot rides on the ratch 3, was used for preventing stressed rear rotation.
