Abstract
The utility model relates to a threshing element for threshing device of a full-feed harvesting machine, which belongs to the technical field of full-feed combine harvester threshing devices of agricultural machinery. The threshing element comprises a threaded-bar tool tooth component and a seat, and the threaded-bar tool tooth component is composed of tool-shaped teeth and an arch threaded bar. Crops are hit and stricken by the tool-shaped teeth and rubbed by the arch threaded bar simultaneously to be threshed. The threshing element has a rubbing threshing function by the threaded bar and a striking threshing function by the tool-shaped teeth, is soft in effect, low in seed injury, high in threshing rate and less in threshed impurities during threshing, is convenient in processing and manufacture, simple in structure, high in applicability and high in universality, and meets threshing requirements of various crops such as rice, rape, wheat, soybean, maize and the like.
Description
Technical field
The utility model belongs to all feeding-in combine sheller unit technical field in a kind of agricultural machinery, mainly is applicable to the threshing of various crop such as paddy rice, rape, wheat, soybean, corn.
Background technology
The function of harvest machinery sheller unit is that seed is taken off from the fringe head in the agricultural machinery, and reduces fragmentation, the raising results quality of seed as far as possible, keeps the integrality of stem stalk, reduces and deviates from assorted surplus content in the mixture, alleviates follow-up cleaning load.The threshing element directly contacts with crop during the crop threshing, mainly contains to impact threshing, rubbing threshing, roll threshing, curry threshing and vibrate five kinds of principles of threshing.The threshing element that combine is commonly used both at home and abroad mainly contains A type rasp bar, D type rasp bar, wedge shape spike-tooth, knife-edge spike-tooth, rod spike-tooth and various types of bow teeth etc. at present.The bow tooth is mainly used on the half feeding threshing cylinder, relies on the effect curried to realize threshing, and all feeding-in combine mainly adopts rasp bar and two kinds of threshing elements of spike-tooth.Threshing cylinder with rib mainly relies on the long rasp bar that is installed on the polygonal width of cloth dish that the rubbing of crop is used to realize the threshing of seed, rub effective, main results wheat, rape and the corn of being fit to.But during the moist crop of results paddy rice, especially high-yield rice etc., exist easily stop up, power consumption is bigger, threshing performance and paddy shell-breaking rate be not than problems such as height.Threshing cylinder with teeth mainly relies on the severe impact effect of spike-tooth to realize the threshing of crop, and threshing performance is higher, is mainly used in paddy rice and soybean, and especially difficulty is taken off kind.When being used to gather in the crops easy broken kind such as rape, corn, the seed damage is serious, the stem stalk is broken into silk, deviates from the mixture assorted surplus a lot, and follow-up cleaning load is serious, causes the seed percentage of impurity obviously to rise.During the relatively poor siliqua of oilseed rape of results maturity, can cause even more serious paste sieve phenomenon, machine can't operate as normal.
In recent years, be threshing performance that improves seed on the material and the fragmentation damage that reduces seed, numerous enterprises focuses on the parameter study of threshing cylinder, and is less to the innovation research of threshing element, threshing principle.In order to strengthen the effect of traditional threshing element; someone has invented threshing tooth (CN02278912.X) on lengthening threshing groove bar (CN200620020798.7), harvester threshing drum threshing tooth (CN200720062240.X), a kind of paddy-eliminator etc.; but fail to take into account the advantage of two kinds of threshing elements rubbing threshing and impacting and find best equalization point in the threshing.Stand and field trial show, the threshing performance of threshing element and material, entrainment loss, seed damage, to deviate from the mixture threshing performance indications such as assorted surplus content closely related.The utility model proposes at the problems referred to above.
Summary of the invention
The utility model purpose is to provide a kind of novel threshing element for harvest machinery, have the advantage of rubbing threshing and impacting threshing concurrently, satisfy the threshing performance height of sheller unit, a plurality of conditions such as entrainment loss is little, and the seed damage rate is little, and percentage of impurity is few in the emersion object, be applicable to the threshing requirement of various crop such as paddy rice, rape, wheat, soybean and corn, adaptability to operating condition is strong, convenient processing and manufacture, and versatility is good.
The purpose of this utility model realizes by the following technical solutions:
A kind of threshing element comprises rasp bar tooth assembly and base, the rasp bar tooth assembly is made up of knife-edge tooth and arc rasp bar, is one on knife-edge tooth and the arc rasp bar structure, and the cross section of arc rasp bar is arc, the knife-edge tooth is positioned at a side of arc rasp bar, and the rasp bar tooth assembly is installed on the base seat.
Knife-edge tooth height in the rasp bar tooth assembly is 1.5-5 a times of arc rasp bar height, and the rasp bar tooth assembly is wear-resisting accurate steel-casting, and arc rasp bar middle part is cast with through hole, can be connected and fixed by bolt with base.
The beneficial effects of the utility model are, soft, the seed of effect damages that little percentage of damage is low in the detach procedure, seed threshing performance height, the assorted surplus content of emersion object are few, have higher results quality, and the integrality of stem stalk is good after the threshing.

Embodiment
Provide further describing of a kind of threshing element below in conjunction with accompanying drawing.
The general structure of threshing element as Figure 1-3, the rasp bar tooth assembly 1 that wear-resisting accurate steel-casting is made is positioned at the top of base 2, through hole by arc rasp bar 102 middle parts adopts the form and the base 2 that are threaded to be fixed together, and knife-edge tooth 101 and arc rasp bar 102 combine together.Screw thread on the arc rasp bar 102 is equidistant.In conjunction with Fig. 4-5, when results paddy rice difficulty is taken off crop, knife-edge tooth 101 is positioned at a side of arc rasp bar 102, strengthen the threshing ability of impacting, get knife-edge tooth 101 this moment and highly be arc rasp bar 102 arch height 1.5-5 doubly, knife-edge tooth 101 thickness in the rasp bar tooth assembly 1 are 0.5-1.2 times of arch height of arc rasp bar 102; In conjunction with Fig. 6, when results rape, wheat etc. easily take off crop, knife-edge tooth 101 is positioned at the opposite side of arc rasp bar 102, strengthen the threshing ability of rubbing, get knife-edge tooth 101 this moment and highly be rasp bar 102 arch height 1.5-3 doubly, knife-edge tooth 101 thickness in the rasp bar tooth assembly 1 are 0.8-1 times of arch height of arc rasp bar 102.
