Description
Technical field
The present invention relates to a kind of installed threshing separator of harvest machinery, the present invention is a kind of longitudinally axial flow threshing and separating installation in particular.
Background technology
The general employing of existing longitudinal axis stream combined harvester cut stream and longitudinal axis stream combined type installed threshing separator, comprises and cuts flow threshing device, auxiliary feeding unit and longitudinal axis flow point from device.Cut flow threshing device and adopt nail tooth drum more, the results paddy rice especially during high-yield rice the seed breakage rate higher, power consumption is bigger.Chinese patent ZL 03250419.5 disclosed control of cutting rheology longitudinal axis stream is made up of light tube and tooth plate cylinder with the auxiliary feeding unit in the longitudinal axis stream combined type installed threshing separator with combining device and the Chinese patent ZL 00137715.9 disclosed stream of cutting, there is not helical blade on the tooth plate cylinder, only depend on deflector to realize the contraction of crop, stop up easily during the operation of big feed quantity, to disposing the machine of two longitudinal axis flow points from cylinder, the feeding of two separation barrels is inhomogeneous during operation.Generally speaking, existing cut that stream is big with the obstruction easily of longitudinal axis stream combined type installed threshing separator crop, complex structure, volume and power consumption, cost is higher, generally be configured on the large-scale combine.
Summary of the invention
Technical problem to be solved by this invention is to overcome big, the more high shortcoming of cost of crop obstruction easily, complex structure, volume and power consumption that existing longitudinally axial flow threshing and separating installation exists, a kind of longitudinally axial flow threshing and separating installation that is fit to middle-size and small-size combine is provided, the crop that suitable feed quantity is bigger, and feed even, smooth and easy, low price, simple in structure, volume is little.
The technical solution adopted in the present invention is: a kind of longitudinally axial flow threshing and separating installation, it is characterized in that, include auxiliary feeding installed threshing separator and longitudinally axial flow threshing and separating installation, auxiliary feeding installed threshing separator is made up of auxiliary feeding threshing cylinder, upper cover plate and notch board, and longitudinally axial flow threshing and separating installation is by kuppe, feeding auger, top cover, longitudinally axial flow threshing separation barrel and separate notch board and form.
Described auxiliary feeding threshing cylinder adopts helical blade-trapezoidal plate tooth composite construction, and auxiliary feeding threshing cylinder top is equipped with upper cover plate, and the bottom is equipped with the punching notch board.
4-8 group trapezoidal plate tooth is installed on the described auxiliary feeding threshing cylinder, along the circumferential direction evenly distributes, helical blade be positioned at auxiliary feeding threshing cylinder place, axial two ends and rotation direction opposite, the logarithm of helical blade is corresponding with the group number of trapezoidal plate tooth; For two longitudinally axial flow threshing and separating installations, the helical blade rotation direction with the place, two ends is opposite respectively for the helical blade rotation direction that install at auxiliary feeding threshing cylinder middle part, and the logarithm of helical blade is corresponding with the group number of trapezoidal plate tooth.
Described longitudinally axial flow threshing separation barrel the place ahead is equipped with feeding auger, and top cover is installed in the top of longitudinally axial flow threshing separation barrel, separates notch board and is positioned at longitudinally axial flow threshing separation barrel below, and kuppe is between upper cover plate and top cover.
Described separation notch board is made up of water conservancy diversion notch board and grid concave plate, and the water conservancy diversion concave length is identical with feeding auger length.For single longitudinally axial flow threshing and separating installation, separate notch board and comprise first section right water conservancy diversion notch board, second section right grid concave plate and the 3rd section right grid concave plate; Separate notch board for two longitudinally axial flow threshing and separating installations and comprise first section right water conservancy diversion notch board, first section left water conservancy diversion notch board, second section right grid concave plate, second section left grid concave plate, the 3rd section right grid concave plate and the 3rd section left grid concave plate.
The invention has the beneficial effects as follows, the function of cutting flow threshing device and auxiliary feeding unit in traditional longitudinally axial flow threshing and separating installation is united two into one, threshing performance height, seed damage and entrainment loss are few, and be simple in structure, volume is little, arrange on practical, the easier middle-size and small-size combine of accepting in the most of market of China.Under the effect of trapezoidal plate tooth, carry out earlier threshing through the material that delivery chute is sent here, and separate from the punching notch board, obtained under the effect by auxiliary feeding threshing cylinder helical blade again forcing to shrink, evenly send into longitudinal axis stream roller smoothly, also realized preliminary threshing function simultaneously.After material entered longitudinally axial flow threshing and separating installation, further by threshing, separation, the load of longitudinally axial flow threshing and separating installation was light at this moment, power consumption is little, and assorted surplus few in the emersion object, suitable feed quantity is big, the higher results of efficient.
