Abstract

The utility model relates to an agricultural machine, particularly a small-sized pulverizing machine which is mainly used for pulverizing crop straws, corns, etc. into coarse and fine feeds. The utility model is characterized in that the side wall of a fan casing of a fan discharge device is fixed on a left bearing seat of the machine; an air inlet of the fan is connected with an air outlet on the side wall of a lower casing of a pulverizing chamber through a connecting pipe; the air outlet of the fan casing is connected with an upper setting type discharge pipe. Compared with a traditional pulverizing machine, the productivity of straw pulverization is improved; when the opening degree of a regulating plate arranged on an underneath type discharge opening is properly regulated, corn flour is discharged from an outlet of the fan discharge device, and corn dregs are discharged from the underneath type discharge opening; accordingly, the separation of the flour and the dregs is realized.

Description

A kind of small-sized tangerine bar pulverizer

The utility model relates to a kind of agricultural machinery, specifically it be a kind of be mainly used to crops tangerine bar and cereal etc. be ground into slightly, the micromill of concentrated feed.

The military pulverizer (hereinafter to be referred as traditional machine) of small-sized hammer leaf commonly used is limit because of the structure configuration all not have the fan drawing mechanism.When pulverizing the dried tangerine bar of crop, because weight is little difficult from the discharge of underneath type discharging opening by deadweight, thereby productivity ratio is lower by the crushed material after pulverizing.During tradition machine crushing maize seed, can only be corn flour and corn from the discharge of underneath type discharging opening by crushed material Sub-mixture (used as fodder).

The purpose of this utility model provide a kind of realize pulverized material (face and

Son) separates discharge, pulverize the high small-sized tangerine bar pulverizer of production efficiency.

Technology emphasis of the present utility model is: it is made up of feed hopper, pulverizing chamber, underneath type discharge bucket, fan drawing mechanism, left and right sides support, transmission device, it is characterized in that the fan drawing mechanism is fixed on the left shaft holder of this machine by a sidewall of fan drum: the air inlet of fan links to each other by the air outlet on the lower house sidewall of connecting tube and pulverizing chamber, the impeller of fan is fastened to the main shaft end of the pulverizing hammer leaf rotor assembly in the pulverizing chamber, and the discharge pipe of fan drum joins with the overhead discharge nozzle.

The utility model is compared with traditional pulverizer, improved the productivity ratio of pulverizing the tangerine bar, suitably regulated the adjustable plate aperture that is provided with on the underneath type discharging opening, what then discharge through fan drawing mechanism outlet is corn flour, what discharge through the underneath type discharge gate then is the corn bits, realization face and

Son separates, and welcome by rural subscribers.As cut off fan assembly, and open the adjustable plate on the underneath type discharging opening, when then finishing this operation, what the underneath type discharging opening was discharged also is corn flour and corn Mixture.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is the utility model partial structurtes schematic diagrames.

The utility model has kept the underneath type discharge bucket of traditional machine, but has set up discharging adjustable plate (19) on this discharge bucket housing (17); The end of the hammer leaf (7) of the grinding rotor in its pulverizing chamber and be installed in gap delta value between the sieve sheet (11) on the pulverizing chamber lower house (10) greater than the δ value of traditional machine, δ value excursion of the present utility model is 10～30mm.This also is that the utility model service behaviour index when pulverizing the stalk kind material is better than one of major reason of traditional machine.

Fan drawing mechanism (see figure 1) of the present utility model mainly is made up of fan hub (1), blast fan (2), connecting tube (3), overhead discharge nozzle (4) etc., and this device is fixed on this utility model by three bolts with the fan hub sidewall paneling and pulverizes on the left shaft holder (5) of roller assembly.The upper and lower side of connecting tube (3) respectively with the sidewall of pulverizing chamber lower house (10) on the air outlet pipe and the blast pipe on the fan hub (1) connect.The blast fan diameter is 80～200mm, and six blades are housed on the blast fan, and width of blade is 20～60mm, and blast fan is threadedly secured in main shaft (8) end of pulverizing the hammer leaf rotor assembly.

The pulverizing chamber of pulverizing chamber of the present utility model and traditional machine basic identical (seeing Fig. 1,2,3), mainly form by upper shell (6), lower house (10), sieve sheet (11), pulverizing hammer leaf rotor assembly (7) etc., upper shell (6) is gone up fixedly dental lamina (22), lower house (10) is being fixed sieve sheet (11) between the two side, according to the sieve sheet in the replaceable different apertures of granularity requirements of pulverizing different material.Above-mentioned all pulverizing chamber space that constitutes a sealing, when pulverizing hammer leaf rotor assembly rotated with the 4000r/min rotating speed, the hammer leaf outer end formed a circus movement trajectory, and this trajectory forms a gap delta with the sieve plate inner surface, is called hammer and sieves the gap.Another feature of the present utility model be exactly the excursion of hammer sieve gap delta value be 10～30mm, greater than the δ value of traditional machine.Feeding hopper (21) is being fixed with the bolt group in the porch of the upper shell of pulverizing chamber (6), the lower house of pulverizing chamber (10) lower plane is fixed left and right support (16) and (15) respectively by four groups of bolts (20), on two stands and between the lower casing lower plane by the clamping force of the fastening generation of above-mentioned four groups of bolts (20) fastening underneath type discharging bucket body (17).On this bucket body, fixing adjustable plate (19) with wing nut and bolt (18).

This utility model selects for use the single-phase fractional electric motor of 1.5～1.8KW (14) by being bolted on the right support (15), the double flute vee-pulley (13) of motor shaft end drives pulley concial disks (9) and makes and pulverize the rotating speed rotation with 4000r/min of hammer leaf rotor assembly and blast fan (2) through two V-belts (12), thereby guarantee that this utility model has good smashing capability, and make the fan drawing mechanism produce enough suction, be convenient to discharging.

This utility model adopts by the pulverizing raw material and tangentially feeds, its course of work is: after raw material is sent into pulverizing chamber by receiving cone (21), with the strike of the hammer leaf (7) of 4000r/min rotating speed rotation with rub down and pulverized, when raw material pulverizing behind certain particle size, under the effect of centrifugal force and air-flow, pass sieve aperture, pass a material material of sieve aperture and fan that powder is rotated in the following thorax of pulverizing chamber lower house (10) in connecting tube (3) suction fan shell (1) body, discharge outside the body be admitted to overhead discharge nozzle (4) along with the rotation of blast fan (2) after.

Do not use the fan drawing mechanism during feeds such as processing greenfeed or corn, soybean, soya-bean cake, only by underneath type discharge bucket (17) discharging.

Processing corn flour and corn The period of the day from 11 p.m. to 1 a.m, two kinds of drawing mechanisms use simultaneously, and the aperture by the adjustable plate (19) on the suitable adjustment underneath type discharge bucket (17) obtains desirable discharging effect, and this also is one of principal character of the present utility model.
