Abstract
A threshing and separating device for a grain combine harvester comprises a screw conveyer blade, spike teeth, an upper flow guide cover, a concave plate, a feeding opening, a grass removing wheel and an axial flow roller. The screw conveyer blade in a spiral shape is arranged at the front portion of the axial flow roller, at least four rows of spike tooth plates are arranged at the periphery of the axial flow roller, the spike teeth are arranged on the spike tooth plates, the upper flow guide cover is arranged at the upper portion of the axial flow roller in a covering mode, the concave plate is arranged at the lower portion of the axial flow roller, the feeding opening is formed in the front portion of the concave plate, and the grass removing wheel is arranged at the rear portion of the axial flow roller, a spiral flow guide plate is arranged on the upper flow guide cover, and a scraper blade and a mesh screen are arranged on the concave plate. Due to open type axial flow, the threshing and separating device is large in space and can accommodate more crops. Furthermore, the crops are in loose states, so that the working resistance is low, and seeds wrapped by the crops can be easily separated out. The spike teeth in finger shapes are good in axial generality, the seed breaking rate is low, and various kinds of crops can be threshed without replacing threshing components. Thus, the problems that a harvester in the prior art is single in operation, low in efficiency, high in grain seed breaking rate and large in residue are solved.
Description
Technical field
The utility model belongs to harvest machinery field, relates to a kind of grain combined harvester Q granule disengaging gear.
Background technology
At present, along with national policy is to the vigorously supporting of agriculture, rural areas and farmers industry, the enthusiasm that peasant plants grain greatly improves, and grain yield constantly increases, and traditional harvest machinery in the past can not meet peasant's demand.Improving grain quality, reduce grain loss, is the developing direction of combined harvester.The installed threshing separator of so-called grain header, in grain header harvesting, automatically complete the threshing of cereal, with the operation such as straw separates.Single, the closed installed threshing separator of the many employings of grain combine of the prior art, that is: a kind of main frame of model can only be gathered in the crops monocrop, host computer using rate is low, can not meet the need of production of peasant household's several work, and has the shortcomings such as imperfect, the assorted reinforcement of threshing, speed be slow.Therefore, develop a kind of a tractor serves several purposes, easy to operate, service-strong grain combine multifunctional threshing separator is very necessary.
Utility model content
The purpose of this utility model is to provide a kind of a tractor serves several purposes, easy to operate, service-strong grain combined harvester Q granule disengaging gear.
Technical solutions of the utility model are: grain combined harvester Q granule disengaging gear, comprising: screw feeder blade, spike-tooth, upper kuppe, notch board, charging aperture, grass-removing wheel, axial-flow type drum; The front portion of axial-flow type drum is provided with spiral-shaped screw feeder blade, and axial-flow type drum periphery setting at least four nail tooth plates, are provided with spike-tooth on spike-tooth plate, axial-flow type drum top covers installs kuppe, notch board is installed in bottom, the anterior charging aperture of installing of notch board, and grass-removing wheel is installed at axial-flow type drum rear portion.
On upper kuppe, be provided with spiral deflector, on notch board, be provided with scraper plate and mesh screen.
The utility model adopts the good effect producing after technique scheme to be: this grain combined harvester Q granule disengaging gear, apply open axial flow, space is larger, can hold more crop, the state of crop is fluffy, working resistance is low, and the seed being wrapped in crop also can more easily be separated.The axial flow versatility of finger-like spike-tooth design is good, and seed damage rate is low, does not need to change threshing unit and just can carry out threshing to various crop.Solved grain header single homework of the prior art, the problem such as efficiency is low, grain seed damage rate is high, assorted Yu Duo.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model grain combined harvester Q granule disengaging gear;
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of the utility model grain combined harvester Q granule disengaging gear.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.As shown in Figure 1 and 2, grain combined harvester Q granule disengaging gear, comprising: screw feeder blade 1, spike-tooth 2, upper kuppe 3, notch board 4, charging aperture 5, grass-removing wheel 6, axial-flow type drum 7, spike-tooth plate 8; The front portion of axial-flow type drum 7 is provided with spiral-shaped screw feeder blade 1, axial-flow type drum 7 periphery setting at least four nail tooth plates 8, on spike-tooth plate 8, be provided with spike-tooth 2, axial-flow type drum 7 tops cover installs kuppe 3, notch board 4 is installed in bottom, the anterior charging aperture 5 of installing of notch board 4, grass-removing wheel 6 is installed at axial-flow type drum 7 rear portions.On upper kuppe 3, be provided with spiral deflector, on notch board 4, be provided with scraper plate and mesh screen.
Grain header is in the time of threshing mask work, crop enters this device by charging aperture 5, by the anterior spiral-shaped screw feeder blade 1 arranging of axial-flow type drum 7 of rotation, crop is stirred into axial-flow type drum 7 again, by the spike-tooth 2 arranging on spike-tooth plate 8, crop rotation is got rid of again, transmit rearward crop by the spiral deflector on upper kuppe 3, transmit the scraper plate simultaneously passing through on notch board 4 crop through threshing, crop kernel is drained to and on the shuttle board on main frame, is entered clean grain device by the mesh screen gap on notch board 4, straw enters grass-removing wheel 6 by the spiral deflector on upper kuppe 3, grass-removing wheel 6 is discharged grass by rotation, thereby complete the threshing separation process of cereal.This axial flow device has adopted conical drum design, and to crop good separating effect, upper kuppe 3 adopts trapezoidal design, and notch board 4 adopts arc design, better to crop Threshing.
