Abstract

The utility model relates to a breaking machine for coarse fodders, belonging to a stockbreeding machine. The utility model which has simple structure, small volume, low energy consumption, and high efficiency can process straw and hay to be softer to feed a ruminant domestic animal such as a cattle, a sheep, etc., and is composed of a casing, a lower casing, a hammer rotor, a fixed knife, a throwing impeller and an inclined tooth plate. The material spirals under the action of air current of the hammer rotor, the inclined tooth plate and the throwing impeller in a breading chamber; meanwhile the volume and the arranged state of the material are changed continuously to achieve the sufficient strike, shearing and kneading, and the material quickly disintegrated can be sent into a wind box to be thrown out of the body of the machine.

Description

Breaking machine for coarse fodder

The utility model belongs to stockbreeding machine, is mainly used in roughage processing such as straw, herbage.

At present, generally adopt beater disintegrating machine processing roughage both at home and abroad, the pulverizing chamber of this cracker is a contained work station, has the sieve sheet.With this cracker processing roughage, because material circulation repeatedly in crushing chamber repeatedly smashed, so power consumption is big, higher 2～3 times than open type, productivity ratio is low, and is unsuitable for processing the higher roughage of moisture.Moisture is higher than at 25% o'clock, and sieve aperture stops up easily, and productivity ratio sharply descends.In addition, processing back overbreak material and Dust Capacity are big, not too are suitable for processing the roughage of ruminant domestic animals such as direct feeding cattle and sheep such as straw, herbage.Close with the present invention is United States Patent (USP) " the rotary bucket formula cracker of US.Patent, 4.106.706 Bruce company; pulverizing chamber is an open type; the advantage of this type just is that without sieve power consumption is compared with the cracker of enclosed pulverizing chamber can reduce by 2～3 times.Can process the higher material of moisture content, but because of this cracker comminuting matter mainly is to pulverize by the strike of hammer leaf and the strong effect of hitting bar, and send the effect body of dishing out by the strike of hammer leaf with by the wind that its produces, therefore overbreak is more in the material after pulverizing, this is unfavorable to feeding ruminant domestic animals such as raising cattle and sheep, throwing after material is pulverized send distance too short, need add blowing device in case of necessity.Simultaneously, material is played hitting about 90 degree of cornerite that the rod-type notch board only accounts for whole bucket of pulverization, service area is shorter relatively, if it is too short to hit the useful effect section of rod-type notch board when adopting the minor diameter rotor, can not effectively finish material grinding, therefore the cracker of this structure can only be large-scale facility, and mating power is big, only is suitable for medium-sized and large-scale pasture and uses.

Aim of the present utility model just is to solve the weak point that exists in the prior art, realizes the roughage of high efficiency, low power consuming, processing be suitable for directly the feeding purpose of ruminant domestic animals such as cattle and sheep with small machine.

For achieving the above object, the utility model has structurally mainly been done following design: the one, and rub broken chamber and form by upper shell and lower house, except that the charging aperture place was fixed with a tabula rasa, all the other whole garden cylinders were fixed with 5～7 blocks of helical teeth plates in the upper shell.The charging aperture place is equipped with tabula rasa in the lower house, is equipped with 1～3 block of helical teeth plate along the rotor direction of rotation near tabula rasa, is equipped with a row 4～6 again in proper order stationary knife and at least one block of helical teeth plate near the helical teeth plate.Wholely like this rub broken chamber except that feeding mouth, surrounded by tabula rasa, helical teeth plate, stationary knife fully, service area has extended.Enough material strike, shearing, kneading action sections are provided under the situation for the minor diameter rotor, have guaranteed the miniaturization of facility.

Another key of the present utility model is, adopted the helical teeth plate that becomes the tooth depth height, becomes the space width gap, promptly the tooth depth along the direction of rotation helical teeth plate of hammer slice type rotor is from low to high, the teeth groove groove width is leniently to arrive narrow variation, thereby hammer slice type epitrochanterian hammer leaf top and the descending variation repeatedly of helical teeth plate tip clearance that rotation is got up, like this, material is in rubbing the broken indoor process that moves in a circle, constantly change volume and ordered state, help material and fully rubbed and the fragmentation of straw firmly, strengthened kneading action.And owing to adopted the helical teeth plate, the tooth of all helical teeth plates and hammer leaf Plane of rotation send the impeller direction to tilt at an angle to throwing, the tangent value of angle is less than the coefficient of friction of material to tooth plate, strengthen material trend to the air compartment motion under the effect of hammer leaf, make to enter and rubbed broken material in the groove in time along flank of tooth oblique movement, hightail the helical teeth plate and enter air compartment and dished out, this has strengthened the kneading action of helical teeth plate to material undoubtedly, has reduced the generation of overbreak material simultaneously.Simultaneously, do not rubbed broken material a little less than the trend of air compartment motion, thereby increased the chance of being hit, shearing, rubbing, guaranteed the abundant pulverizing of material, promptly avoided because material by the broken power consumption that causes of rubbing of overbreak, makes material evenly be pulverized again.

Another key of the present utility model is exactly that the broken chamber of rubbing at hammer slice type rotor place communicates with air compartment---be called the open type pulverizing chamber, it exactly is laterally opened pulverizing chamber, rub on the axis of broken chamber and be equipped with the hammer slice type rotor, with the hammer leaf rotor coaxial throwing that places in the air compartment is installed and send impeller.This structure that is combined as a whole makes power consumption descend greatly and the raising of productivity ratio, and has guaranteed crudy.Throwing is sent impeller to make and is rubbed broken material throwing distance increase greatly.Owing to be that open type is rubbed broken chamber,, make the moisture content adaptability of material strong without sieve.

Advantage of the present utility model is: solved the deficiency that exists in the prior art, volume is little, simple in structure, power consumption is low, efficient is high, throwing send distance big, can process the higher straw of moisture content and freeze straw, and the processing corn stalk is thread, other leather stoking, cattle and sheep are liked to search for food.
