Description

The broken separator of multi-functional aspiration type hand hay cutter grass meal

The utility model relates to and a kind ofly is used in that hand hay cutter is cut, the forage grass and feed processing equipment of pulverizing, grain cleaning.

Be used to cut up with a hay cutter forage grass, the feed processing machinery cutting, pulverize many types are arranged at present, but all be the preliminary roughing plant equipment of single goal mostly, only corn stalk there is good grinding and processing effect as some machinery, but the processing effect to wheat, beans, cereal crop stalk just can not be satisfactory, some machinery consumes energy very high when the grinding particulate feed, and crushing effect is also bad.Become today of China's agricultural development, the developing focus that attracts people's attention of poultry industry in effective development and use of crop stalk, vast agriculture and animal husbandry family presses for a kind of machinery that can process effectively forage grass, feed.

The purpose of this utility model be to provide a kind of cut up with a hay cutter cut, pulverizing, the forage grass of grain cleaning, feed processing machinery, can be used for hand hay cutter and cut multiple forage grasses such as dried corn, clover, straw, millet straw, wheat straw, straw can be processed into soft thread, also can be used for pulverizing various grains and feed, as corn, wheat, corn ear, beans; Also can be used for the operation of cleaning of multiple kinds of crops particle.

This practical purpose is achieved in that at a garden column type housing inner chamber installs a rotating spindle (being called main shaft), this belt pulley by hull outside drives and rotates, axis and garden post central lines, dividing plate perpendicular to main shaft is divided into two parts of pulverizing chamber and air-suction chamber with inner chamber, a passage that communicates is arranged on the top of two chambers, can insert a sieve sheet between this passage, the sieve sheet is positioned at pulverizing chamber top, arranges with the involute expansion mode in the housing outer; On pulverizing chamber one side body, have feeding mouth, feeding mouth lower edge sharper keen (being called the stationary knife seat); The main shaft of pulverizing chamber inside drives hammer leaf and blade (being called moving knife) rotates, and in the design of pulverizing chamber Lower Half tooth plate, the tooth on the tooth plate being arranged is the bar shaped arranged askew, with main shaft at an angle, main axis rotation direction and helical teeth direction are backwards rotation in the running.Housing the place ahead has exhaust outlet, and exhaust outlet is connected with exhaust duct, with ground angle 30 degree, on the exhaust duct design clean, the batch mixing bucket, the fan blade that the main shaft of air-suction chamber inside drives on the main shaft rotates.Blade is a central symmetry axis with the main shaft, and five equilibrium is evenly distributed, and during operation, blade provides malleation to exhaust outlet.In addition, design has the suspension governor motion on the case body of machinery, for being welded on the steel plate on the housing, on the eye that can insert screw rod is arranged, can be with it with this mechanical suspension in the tractor front-axle beam, drive mechanical belt pulley by the tractor engine driving wheel and rotate, provide power to machinery, also can be by electromotor, diesel engine drive work.Operation principle: the driving wheel of tractor engine rotates by the follower that three Type B V belts drive this mechanism; main shaft is rotated; blade rotation in the air-suction chamber provides malleation to exhaust outlet; the discharge gate place is a negative pressure; enter the cutting knife that the material of pulverizing chamber is rotated by charging aperture; the synchronous hand hay cutter of hammer leaf is cut; hit; pulverize; the rubbing effect; under the drive of air-flow, make broken material continuously be subjected to hammer leaf along wall; tooth plate; hit collision and be ground into particle or grass section rapidly; particle is delivered to air-suction chamber because of thrown by sieve aperture rapidly by the rotor centrifugal action; discharge by exhaust outlet; chopping grass section is directly discharged from the air port by blower fan during chaffcutter; the length of hand hay cutter chaffcutter section is then stretched into the length adjustment of passage (discharge gate) by the sieve sheet, the fineness of a feed material then realizes by the sieve sheet of changing different apertures.

Compare with machinery in the past, this machine has many advantages: this machine is suspended on the tractor front-axle beam and drives belt pulley work by the engine driving wheel, articulates easy and conveniently moving, is specially adapted to the outlying district that peasants and herdsmen raiser and middle ranchette or electric power lack; This machine is realized the grass after forage grass, stalk and all feeds are set out to import and process, the output of material by aspiration mechanism, and handling safety is reliable; This function realizes that straw is pulverized, the forage grass hand hay cutter is cut, feed is pulverized, crop grain is winnowed and cleaned, functions such as the even mixing of feed supplement; Main axis rotation direction and tooth plate helical teeth direction are backwards rotation when moving the commentaries on classics, make the granulated meal that is deposited on the pulverizing chamber bottom, under the wind-force effect that driven by hammer leaf, blow afloat, can increase bulky grain is subjected to hammer leaf to hit chance, guaranteed effective momentum, use energy to greatest extent, overcome the barrier layer between the large and small particle that cracker in the past forms when work, waste the shortcoming of energy; The design of sieve sheet arranges with the involute expansion mode that in the housing outer hammer leaf gap when sieving the sheet surface is big, diminishes gradually when leaving, and a material material is increased, to make things convenient for the discharge of material particles to the angle of attack of sieve sheet; Clean the batch mixing bucket and can be conveniently other forage grasses that cut through thick, the concentrated feed or the hand hay cutter of processing be mixed and put in storage, the convenient even mixing that cooperates additive, the air-flow that also can utilize machinery to produce is winnowed and is cleaned operation.
