Abstract
Grain header gathers in cylinder at a high speed, relates to a kind of Novel threshing cylinder of wheat harvester.The present invention is formed jointly by with the cylindrical shell of back shaft, rasp bar section, cutting teeth group and trapezoidal separating plate group, cutting teeth group and trapezoidal separating plate group are embarked on journey according to cylinder uniform spiral curved arrangement along tubular axis direction at drum surface, in the cylindrical shell tangent to periphery direction quartering or the arrangement of six deciles, two adjacent line position left and right stagger arrangement.The present invention is by four bulk separating plates of former wheat harvester axial-flow type drum, redesign as some cutting teeths and the trapezoidal separating plate of some fritters, row and column is become according to cylinder uniform spiral curve ordered arrangement, when grain header is worked, load alleviates 20%-30%, be more suitable for grain header harvesting at a high speed, substantially increase the operating efficiency of grain header.Make grain header in the morning or rainy weather harvesting moist wheat time cylinder do not block, it is more abundant that wheat straw is separated with wheat, and noresidue wheat in the wheat straw of discharge, really makes grain header reach energy-efficient, and then significantly fallen at the end grain header use cost.
Description
Technical field
The invention belongs to technical field of agricultural mechanical equipment, is a kind of Novel threshing cylinder of wheat harvester.
Background technology
At present, the threshing cylinder of wheat harvester on market, be mainly divided into Cylindorical rod streaming and support shaft streaming two kinds, operation principle is roughly the same.The straw transported by conveyer is rubbed through cylinder rasp bar, and then move the separating plate High Rotation Speed through cylinder to cylinder right, under the influence of centrifugal force, wheat is separated with straw, finally by assorted for straw remaining discharge.But when present grain header uses, carry wheat secretly in straw, cylinder very easily blocks, how overweight grain header is negative, and diesel consumption is high.Be badly in need of technological improvement, raise the efficiency.
Summary of the invention
The object of the invention is innovative design on the axial-flow type drum basis of existing wheat harvester, cylinder load is alleviated greatly, and operating efficiency significantly improves.
Technical scheme of the present invention is: the present invention by with back shaft cylindrical shell, be located at the rasp bar section of cylindrical shell left end, on the right of the cutting teeth group on surface, cylindrical shell centre position and cylindrical shell, the trapezoidal separating plate group on surface is formed jointly, cutting teeth group often organizes 3-5 cutting teeth, centre distance 6-10CM, trapezoidal separating plate group often organizes 4-8 trapezoidal separating plate, centre distance 10-15CM; Cutting teeth group and trapezoidal separating plate group are embarked on journey according to cylinder uniform spiral curved arrangement along tubular axis direction at drum surface, the cutting teeth group be arranged in rows and trapezoidal separating plate group arrange in the cylindrical shell tangent to periphery direction quartering or six deciles, two adjacent line position left and right stagger arrangement, cutting teeth and trapezoidal separating plate are distributed on cylindrical shell circumferential surface by above-mentioned arrangement mode.
Beneficial effect of the present invention: the present invention is by four bulk separating plates of former wheat harvester axial-flow type drum, redesign as some cutting teeths and the trapezoidal separating plate of some fritters, row and column is become according to cylinder uniform spiral curve ordered arrangement, when grain header is worked, load alleviates 20%-30%, be more suitable for grain header harvesting at a high speed, substantially increase the operating efficiency of grain header.The present invention make grain header in the morning or rainy weather harvesting moist wheat time cylinder do not block, it is more abundant that wheat straw is separated with wheat, and noresidue wheat in the wheat straw of discharge, really makes grain header reach energy-efficient, and then significantly fallen at the end grain header use cost.

embodiment one
The present invention is formed jointly by with the trapezoidal separating plate group on surface on the right of the cutting teeth group on the cylindrical shell 1 of back shaft 2, the rasp bar section 3 being located at cylindrical shell 1 left end, surface, cylindrical shell 1 centre position and cylindrical shell 1 as shown in Figure 1.Wherein cutting teeth group often organizes three cutting teeths 4, centre distance 9CM, and trapezoidal separating plate group often organizes four trapezoidal separating plates 5, center distance 12CM.Cylindrical shell 1 right-hand member has one to widen trapezoidal separating plate to follow closely after one's own profession the 4th trapezoidal separating plate 5.
Cutting teeth 4 structure is shown in that, shown in accompanying drawing 5, accompanying drawing 6, be strip cuboid, its front upper portion has inclination corner cut 4-1.Cutting teeth size is defined as: height 9-13CM, width 0.5-1.5CM, thickness 3-5CM, selects to be of a size of 10 × 1 × 4CM(herein high × wide × thick).Lower end is welded on cylindrical shell 1 on the surface.
Trapezoidal separating plate 5 structure and support 7 installation method are shown in shown in accompanying drawing 2, accompanying drawing 3, accompanying drawing 4.Trapezoidal separating plate 5 is fixed on support 7 by set bolt 8, and support 7 is welded on cylindrical shell 1 on the surface.The size of trapezoidal separating plate 5 is defined as: be highly 10-13CM, top width 4-7CM, following width is 6-9CM, selects to be of a size of high × upper hem width × lower hem width of 11 × 6 × 8CM(herein).
Can select to be installed as trapezoidal separating plate 5 or a widened trapezoidal separating plate 6 at cylindrical shell 1 low order end, widened separating plate 6 height is consistent with trapezoidal separating plate 5, and upper hem width 20-23CM, lower hem width 24-28CM, plate thickness is 3-5MM.
Cutting teeth group and trapezoidal separating plate group are embarked on journey according to cylinder uniform spiral curved arrangement along cylindrical shell 1 axis direction on cylindrical shell 1 surface, the cutting teeth group be arranged in rows and trapezoidal separating plate group arrange in the cylindrical shell 1 tangent to periphery direction quartering, the stagger arrangement of adjacent rows left and right, cutting teeth 4, trapezoidal separating plate 5, widened trapezoidal separating plate 6 are distributed in cylindrical shell 1 on the surface by above-mentioned arrangement mode.
When different grain headers uses the cylindrical shell 1 of different model, the installation quantity of cutting teeth 4 and trapezoidal separating plate 5 with the corresponding increase and decrease of length of cylindrical shell 1, the trapezoidal separating plate 5 of low order end or widened separating plate 6 and cylindrical shell 1 right-hand member justified margin.
embodiment two
The method of embodiment one is equally applicable to stent-type cylinder, and except cylindrical shell 1 is changed into except stent-type cylindrical shell by closed cylindrical shell, other is identical, repeats no more herein.
