Description

The family expenses husker sheller

Technical field

The utility model relates to a kind of husker sheller in the agricultural mechanical field, a kind of specifically small-sized family expenses husker sheller that can carry out threshing simultaneously and please select function.

Background technology

Existing husker sheller on the market; a kind of is mainframe; the collection harvesting, threshing, clean, pack integrated; can save lot of manpower and material resources; but it is applicable to large stretch of reaping corn; simultaneously also have cost height and the big problem of power consumption, because of acquisition cost and use cost height, peasant household is difficult to bear.Another kind is the small-sized corn thresher of selling at small-sized peasant household; although use that can single household; but adopt the form of corncob feeding mostly; stripping grain efficient is lower, and after corn taken off, can produce a large amount of chips; also will spend a large amount of time cleans; not only trouble also wastes time and energy, and increases labour intensity.

The utility model content:

In order to solve the problem that existing family expenses corn threshing engine efficiency is low and need clean, the utility model provides a kind of family expenses husker sheller.This thresher has the function of cleaning when having improved threshing efficiency, save lot of manpower and material resources.

The technical solution of the utility model is: a kind of family expenses husker sheller comprises frame, the top stationary hopper of described frame; the built-in threshing cylinder of frame; the external part of threshing cylinder is fixed big belt wheel, is provided with bolter below the described threshing cylinder, is provided with sorting screen below the bolter.

For corncob and impurity are separated better with seed, described bolter and sorting screen are obliquely installed in frame; The low side of described bolter is provided with the corncob outlet, and the downside of described sorting screen is provided with the seed blanking port.

Rub effect for threshing cylinder and bolter are formed corn, and prolong rubbing the time of corn and threshing cylinder, above-mentioned threshing cylinder is taper, and the spike-tooth of surface distributed helical pattern, the blanking port of described hopper are positioned at an end of threshing cylinder.

For further removal of contamination, fixing centrifugal blower on the described frame, and described centrifugal blower is positioned on the sorting screen.

In order to save power consumption, the above-mentioned threshing cylinder and the power of centrifugal blower are by same motor-driven.

The beneficial effects of the utility model are: owing to adopt technique scheme, utilize the driven by motor cylinder to carry out threshing, improve threshing efficiency greatly, in frame, be provided with the bolter and the sorting screen of inclination, in threshing, further clean, saved manpower and materials greatly; Adopt same motor-driven threshing cylinder and centrifugal blower simultaneously, when improving threshing efficiency, conservation of power, reduction labour intensity.

1-hopper among the figure, the 2-threshing cylinder, the 3-bolter, 4-corncob outlet, 5-please jig, 6-frame, 7-centrifugal blower, 8-motor, the big belt wheel of 9-, 10-protective cover, 11-spike-tooth, 12-seed blanking port.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Extremely shown in Figure 3 by Fig. 1; this family expenses husker sheller comprises frame 6, threshing cylinder 2, bolter 3 and sorting screen 5, motor 8 and centrifugal blower 7; the hopper 1 of the top fixedly back taper of described frame 6; frame 6 is interior by being fixed on the built-in threshing cylinder 2 of bearing on the frame; the external part of threshing cylinder 2 is fixed big belt wheel 9; be provided with bolter 3 below the described threshing cylinder 2, be provided with sorting screen 5 below the described bolter 3.

For being formed, 3 pairs of corns of threshing cylinder 2 and bolter rub effect, and prolong rubbing the time of corn and threshing cylinder 2, above-mentioned threshing cylinder 2 is taper, the spike-tooth 11 of surface distributed helical pattern, above-mentioned bolter 3 is and the corresponding circular arc of threshing cylinder 2 profiles, is obliquely installed in frame, and 90 to 100mm gaps are left in the gap of the compass screen surface of bolter 3 and threshing cylinder 2, make corncob contact-making surface with threshing cylinder 2 and bolter 3 in rolling bigger, reduce the breakage rate of seed; The frame that is positioned at the lower end of bolter 3 is provided with corncob outlet 4, and the blanking port of above-mentioned hopper 1 is positioned at an end of threshing cylinder 2, make the time lengthening of rubbing of corncob and threshing cylinder and bolter 3, thereby improve the threshing effect, as Fig. 1 and shown in Figure 3.

For the corncob of bulk separates to reaching slightly with the seed of taking off; the sieve aperture of bolter 3 is greater than iblet; the corncob that separates the back bulk tumbles bolter 3 lower ends and gets rid of outside the thresher through corncob outlet 4; on the sorting screen 5 below other effect at gravity drops to; described sorting screen 5 also tilts fixing in frame; be provided with seed blanking port 12 at sorting screen 5 lower ends; the sieve aperture of sorting screen 5 is less than the seed of corn; but chip impurity can fall; fixing centrifugal blower 7 also on described frame 6; and be positioned on the sorting screen 5; after wind-force was cleaned, the impurity of lighter weight was blown outside the machine, heavy slightly corn particle fall into sorting screen 5 below; corn kernel tumbles a lower end above the sorting screen, outside seed blanking port 12 eliminating machines.

In order to save power consumption, above-mentioned threshing cylinder 2 and centrifugal blower 7 are driven by same motor 8, centrifugal blower 7 and motor 8 are fixed on the frame, drive the big belt wheel 9 of belt and cylinder external part by the belt pulley on the motor 8, the driving threshing cylinder rotates, and the belt pulley on the motor 8 drives the centrifugal blower running simultaneously; For safety, described big belt wheel 9, motor 8 and centrifugal blower 7 are covered with protective cover 10, reach as shown in Figure 2 as Fig. 1.

The family expenses husker sheller that adopts technique scheme is when having improved threshing efficiency; time saving and energy saving; has the threshing and cleaning function simultaneously; the corn threshing fragmentation less, seed is neatly clean; characteristics such as the little conveniently moving of machine volume; can take off about 1500 jin of corns every day, be particularly suitable for family and use.
