Abstract

The utility model relates to agricultural machinery, in particular to a mechanical threshing, separating and cleaning device used on a full-feeding grain combine harvester for harvesting grains. The threshing, separating and cleaning device comprises a first concave plate sieve, a first axial flow roller, a first roller cover, a fan, a vibrating sieve body, an upper sieve plate, a lower sieve plate, a second concave plate sieve, a second axial flow roller, a second roller cover, a tail cover, an auger and a frame. The threshing, separating and cleaning device is characterized in that: the first axial flow roller on the first concave plate sieve positioned on the frame adopts a composite structural form, one part is a threaded rod form I, and the other part is a toothed rod form II; and the second axial flow roller adopts the toothed rod form. In the grain harvesting process, the threshing, separating and cleaning are complete and grain losses are low.

Description

The threshing of full feeding millet combine, separation and cleaning plant
Technical field
The utility model relates to a kind of agricultural machinery, mechanical threshing, separation and the cleaning plant of harvesting millet on a kind of specifically all feeding-in combine.
Background technology
A few days ago, the mechanical threshing of all feeding-in combine, separation and cleaning plant are with the axial flow nail tooth drum, the lip(ped) sieve and the mesh screen of grid concave plate sieve and vibratory sieve are widely used, when being widely used, the user thinks more increase operation kinds again, in the threshing of using in the market, in separation and the cleaning plant, lack at grain threshing, separate and the device of cleaning, and there is certain shortcoming and defect part, is in particular in: inevitably will cause the clean entrainment loss problem that totally do not wait of and separate totally and cleaning of threshing at the shelling period of the day from 11 p.m. to 1 a.m.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned prior art deficiency, provides a kind of in the process of harvesting millet, threshing, separate and clean clean, the threshing of full feeding millet combine, separation and the cleaning plant of grain loss minimum.
The purpose of this utility model is to realize like this, this device comprises first concave grate, first axial-flow type drum, first drum cover, blower fan, vibration sieve nest, upper sieve plate, following sieve plate, second concave grate, second axial-flow type drum, second tin roller lid, hood, screw feeder, frame, described first concave grate is installed on the frame, and first axial-flow type drum is arranged on the first concave grate top; The rear portion of described first concave grate is communicated with second concave grate, and second axial-flow type drum is arranged on the top of second concave grate; The bottom of second concave grate is provided with the vibration sieve nest, and upper sieve plate, down sieve plate is arranged in the vibration sieve nest, and screw feeder is installed on the following frame of vibration sieve nest, and blower fan is arranged on a side of vibration sieve nest below the frame.
Described first axial-flow type drum adopts the version of combined type, and wherein a part is rasp bar form I, and another part is ratch form II; Second axial-flow type drum adopts the ratch form.
The linear velocity of the described first axial-flow type drum cylindrical is less than the linear velocity of the second axial-flow type drum cylindrical; Upper sieve plate adopts φ 12 stamped sieves, and following sieve plate adopts φ 6 stamped sieves.
The utility model is owing to adopt said structure, the millet crop carries out threshing and separates with first concave grate through the first axial flow composite roller earlier, entering second axial-flow type drum again carries out threshing and separates with second concave grate, enter then on the upper sieve plate of vibratory sieve and the following sieve plate and clean, realized for the millet crop threshing, separate and clean, have simple and reasonable, threshing, separate and clean advantages such as clean, that grain loss is little.
Description of drawings
Fig. 1 is the utility model overall structure structure chart.
Fig. 2 is the first axial flow composite roller structure structure chart in the utility model.
Embodiment
As shown in Figure 1: this device comprises first concave grate 1, first axial-flow type drum 2, first drum cover 3, blower fan 4, vibration sieve nest 5, upper sieve plate 6, following sieve plate 7, second concave grate 8, second axial-flow type drum 9, second tin roller lid 10, hood 11, screw feeder 12, frame 13, described first concave grate 1 is installed on the frame 13, and first axial-flow type drum 2 is arranged on first concave grate, 1 top; The rear portion of described first concave grate 1 is communicated with the top that second concave grate, 8, the second axial-flow type drums 9 are arranged on second concave grate 8; The bottom of second concave grate 8 is provided with vibration sieve nest 5, and upper sieve plate 6, following sieve plate 7 are arranged in the vibration sieve nest 5, and screw feeder 12 is installed on the following frame 13 of vibration sieve nest 5, and blower fan 4 is arranged on a side of frame 13 following vibration sieve nests 5.
Shown in accompanying drawing 2: described first axial-flow type drum 2 adopts the version of combined type, and wherein a part is rasp bar form I, and another part is ratch form II; Second axial-flow type drum 9 adopts the ratch form.The linear velocity of first axial-flow type drum, 2 cylindricals is less than the linear velocity of second axial-flow type drum, 9 cylindricals; Upper sieve plate 6 adopts φ 12 stamped sieves, and following sieve plate 7 adopts φ 6 stamped sieves.
After adopting said structure, when after crop is cut off by grain header, being transported to threshing and separator, at first be transported to first axial-flow type drum 2 and first concave grate, 1 position, under the interaction of first axial-flow type drum 2 of making circular motion and first concave grate 1, crop is realized the threshing first time of GVG, separate, forward second axial-flow type drum 9 and second concave grate, 8 positions then to, under the interaction of second axial-flow type drum 9 of making circular motion and second concave grate 8, crop realizes that the threshing second time of GVG separates, stalk after the threshing is discharged from outside the machine by the hood 11 of second axial-flow type drum, 9 one sides, remain a small amount of stem stalk and seed, the mixture that the grain husk hull shape becomes is by first concave grate 1, behind second concave grate 8, fall on the vibration sieve nest 5 of double vibrations, vibration sieve nest 5 when making double vibrations under the effect of the blower fan 4 that is installed on vibration sieve nest 5 front portions, seed is cleaned up by upper sieve plate 6 and following sieve plate 7, at last by screw feeder 12 output packings.
