Abstract

The utility model provides a small flour-milling machine whose matched power is about one KW. The utility model can mill wheat, maize, soybean, etc., can mill wheat more than 40 kilograms per KW an hour, is a small-size machine for processing flour, and is suitable for countryside families. The utility model is composed of a grinding body (11), a grinding shaft (5), a material separator (10), an outer grinding head (12), an inner grinding head (16), a nut for adjusting (15), a sieve frame (19), a brush (21), a sieve shell (22), a sieve bottom (23), etc. A definite gap exists between the inner grinding head (16) and the outer grinding head (12) all the time without direct friction.

Description

Small flour-milling machine

The utility model belongs to the flour processing equipment.

The flour milling machine of rural area use at present, efficient is low, every kilowatt-hour of processing wheat 20-25 kilogram.Match power is big, is not suitable for rural households and uses.

It is about 1 kilowatt that the purpose of this utility model provides a kind of match power, can process wheat, corn, soybean etc., and every kilowatt-hour of processing wheat is more than 40 kilograms, and volume is little, and noise is low, and is easy for operation, is fit to the small mill surface machine that rural households use.

Main points of the present utility model are to adopt vertical structure, and the reduction ratio of grain is controlled with the gap that changes between outer bistrique and interior bistrique, and when flour milling process and dry run, interior bistrique and outer bistrique keep certain interval, do not produce direct friction, the bistrique long service life.Flour and wheat bran to separate by a bottom surface be that conical rotary brush sieve is finished.

Below with reference to accompanying drawing this utility structure is described in further detail.

Accompanying drawing is the cutaway view of the utility model concrete structure.

By motor (1), by motor pulley (2), V belt (3), coherence belt pulley (4), mill axle (5) drives spirality tripper (10), interior bistrique (16), scraper plate (20), brush (21) rotation.Grain in the hopper (6) is through the plate of limiting the quantity of (7), feed pipe (9), and tripper (10) enters the clearance control formula flour milling system that is made up of interior bistrique (16) and outer bistrique (12) continuously.The space of the grain muscles along the regular meridians formula bearing block (27) that grinds falls on sieve frame (19), enters flour and wheat bran separating mechanism after the scraper plate (20) of rotation is scraped.The brush of separating mechanism (21) is realized separating of flour and wheat bran net, surface being housed for (23) at the bottom of conical sieve upward rotation.Wheat bran is isolated from bran outlet (25), and flour (23) at the bottom of sieve falls.(22) be sieve shell, (24) play a part to compress at the bottom of sieve and net for compressing pawl.(15) be nut, with outer bistrique (12) threaded engagement, (14) be handle, totally six, by being threaded on the nut (15), (13) be feather key, move handle (14) from the window of bearing block (27), make nut (15) rotation, outer bistrique (12) just produces and moves axially, make the gap between interior bistrique (16) and outer bistrique (12) obtain changing, realize the adjustment of flour milling thickness.Outer bistrique (12) inner chamber is taper, and roll flute is axial straight-tooth.The roll flute of interior bistrique (16) is a spirality.(11) be the mill body, two thrust ball bearings and a radial ball bearing are equipped with in the upper end, and another radial ball bearing is contained on the bearing block (27), and (8) are bearing cap, and (17) are stop nut, and (18) are the outside framework oil seal seat.Motor (1) links to each other with mill body (11) by adjusting screw thread pair (29) (30), and (26) are supporting leg, and (28) are support.

Claims

A kind of small mill surface machine comprises mill body (11), inertia belt pulley (4), mill axle (5), tripper (10), outer bistrique (12), interior bistrique (16), adjust nut (15), bearing block (27), support (28), sieve frame (19), sieve shell (22), brush (21) at the bottom of sieve (23), is characterized in that inner chamber is taper, to be the outer bistrique (12) of axial straight-tooth match with feather key (13) on being fixed on mill body (11) roll flute, outer bistrique (12) external diameter is equipped with one adjusts nut (15), rotation nut (15), outer bistrique (12) moves axially, the change roll flute is the gap between spiral interior bistrique (16) and the outer bistrique (12), and (23) are conical at the bottom of sieve of separating mechanism.
