Description

Double-pole double-sieve type small-sized household rice mill

The utility model relates to a kind of farm machinery, particularly miniature rice mill.

Traditional rice mill casing is made up of upper and lower cover horizontal integration, at a rice of a faying face horizontal setting cutter, the bran sieve is loaded at the bottom of the machine, be hilted broadsword list sieve form, the rice arbor bearing is arranged on casing two outer ends separately, and this structure rice mill has following weak point: 1. hilted broadsword list sieve husk rice working ability is low; 2. owing to being seated against the casing outer end, rice arbor is provided with separately, make rice arbor, bearing and bearing block concentricity not high, not only reduced the service life of rice arbor and bearing, and rice cutter and rice roller tooth muscle gap inequality longitudinally, make some grain laterally enter the slit and grind to become to crack rice, both influence the husk rice quality, increased the weight of load again, increased power consumption; Noise pollution is big when 3. working.Patent ZL87204132 discloses the two sieve of a kind of separate type double-pole emery roll with iron ridge rice whitener, it is divided into two sections scabs to the rice roller, dwindle propeller external diameter and screen frame (unit) charging place gap, and to certain modification of relevant element size work, correspondingly rice cutter and sieve also are divided into two sections and be referred to as the two sieves of double-pole, this structure rice mill working ability has slightly and improves but effect is little, other deficiencies of traditional rice mill is not made improvements, and increased that diamond dust may come off and the hidden danger that is detrimental to health.

The purpose of this utility model provides a kind of husk rice working ability and is significantly increased, good, the mechanical long service life of husk rice quality, the small-sized household rice mill that work operates steadily, noise is low, power consumption is low.

Be the last purpose that realizes, technical solution of the present utility model is that vertical plane combined before and after rice mill support and cover were designed to, rice roller unit oblique crank Z bearing directly is supported on the first arc supporting surface that is arranged on the casing two ends by support, cover and bearing (ball) cover wrap in wherein, thereby guarantee rice arbor, bearing, the height of bearing block is concentric, on the faying face of support and cover, the below respectively has a rice cutter to be vertical layout, each fixes a bran sieve on the casing inner wall of rice roller both sides, both sides respectively have a chaff discharging port corresponding with it before and after the casing, constitute a kind of double-pole double-sieve type small-sized household rice mill.

Above-mentioned support is that top employing hinge type is connected, bolting is adopted in the below with the connected mode of cover; Unit's oblique crank Z bearing is by passing the bolting of casing.

The small-sized household rice mill that adopts above technical scheme to make, hour husk rice processing capacity improves twice than similar traditional type rice mill, and do not go out to crack rice, not only improved the husk rice quality, and alleviated live load, and having reduced power consumption, running is steadily during the work of this stone roller machine machine, noise significantly improves little, mechanical life, fault is few, is particularly suitable for farmers' and uses.This rice mill is simple in structurely tightly played, is made easily in addition, low, the easy realization of cost produces in enormous quantities, owing to adopt unidirectional monophase machine to drive, is easy to the popularization to vast rural farmers' especially.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the positive cross-sectional schematic of the utility model double-pole double-sieve type small-sized household rice mill;

Fig. 2 is that schematic diagram is looked on the utility model double-pole double-sieve type small-sized household rice mill left side;

Fig. 3 is the utility model double-pole double-sieve type small-sized household rice mill B-B cross-sectional schematic;

The support 1 and the cover 2 of Fig. 1, the utility model double-pole double-sieve type small-sized household rice mill shown in Figure 2 are combined into casing by vertical plane 3, the half dollar arc concave surface 4 at support 1 two ends is combined into first shape supporting surface with another half dollar arc concave surface 5 at cover 2 two ends, rice roller 6-1 unit oblique crank Z bearing 6 directly is bearing in and is wrapped in wherein by support 1, cover 2 and bearing (ball) cover 7 on this yuan shape supporting surface and fix by bolt 13, support 1 is connected with hinge 11 with cover 2 tops, and the below is fixing with bolt 12; Shown in Figure 3ly on support 2, be positioned at the faying face upper and lower of cover each and be fixed with a rice cutter 8 with bolt 8-1 and be vertical setting, respectively inlay a bran sieve 9 on the casing inner wall of both sides before and after meter roller 6-1 and fix by bolt 9-1 and be positioned at, both sides respectively have a chaff discharging port 10 corresponding with mesh screen 9 before and after the casing; Rice roller 6-1 external diameter 55mm, the high 5mm of husk rice tooth muscle, the long 200mm of roller, wherein curved muscle section 75mm, straight muscle section 125mm, the long 120mm of mesh screen, radius of curvature 33.5mm; This rice mill adopts the 1.5kw load motor to drive by belt drive unit.Adopt above structure can make a meter roller 6-1, rice arbor 6-2, bearing and first oblique crank Z bearing 6 not only make system's running when work steady highly with one heart on the one hand, noise is little, fault is few, the machinery high life, and owing to crack between rice roller husk rice tooth muscle and the rice cutter 8 is longitudinally evenly constant, avoid grain laterally to enter the gap and caused the phenomenon of cracking rice, when having improved the husk rice quality, alleviate load, reduced power consumption; On the other hand, owing to adopted the husk rice simultaneously of the two sieves of double-pole, the unit hour processing capacity is increased considerably.
