Abstract

The utility model discloses a pulverizer of straws used for feeds and belongs to the technology field of agricultural machinery, and comprises a worm shell, a tubular sieve, an axis of rotation driven by power, a revolving knife, a centrifugal fan, a hammer crusher slice, and is assembled and installed into an entity. The utility model is characterized in that a tubular sieve is arranged in the worm shell, with the center provided with a rotation axis; a revolving knife, a centrifugal fan, a hammer crusher slice are vertically arranged on the rotation axis and the pivot axis line in homogeneous distribution along the circumference. When the axis of rotation drives the revolving knife, the centrifugal fan, and the hammer crusher slice to rotate, the revolving knife cuts off the straws; the straws are crashed by the hammer slice into detritus, which is blown out of the worm shell from the tubular sieve with the fan blade. The utility model integrates the crushing, segregating, conveying the feedstuff in the identical shell. The utility model of a pulverizer of straws used for feeds has the advantages of simple structure, reliable performance, low cost, and worthy of popularization.

Description

Feed straw cracker

One. technical field

The disclosed straw cracker of the utility model belongs to agricultural machinery technological field, is specifically related to a kind of feed straw cracker.

Two. background technology

Feed is in the past pulverized with separating with the straw cracker and is inhaled that to send be separate, and straw is earlier in cracker internal cutting off and fragmentation, then by the sucking-off in the cracker of the material straw of a typhoon machine after fragmentation.Straw mill structure complexity originally, poor reliability, cost height.

Three. summary of the invention

Task of the present utility model is a kind of novel feed straw cracker of development, fragmentation, separation and feeding is combined in the same housing finish.This straw mill structure is simple, dependable performance, and cost is low.

Goal of the invention of the present utility model is to release this novel feed straw cracker to society, for contribution is done some in agricultural mechanization.

This feed straw cracker described in the utility model, it includes volute housing, the barrel-shaped sieve in garden, power-actuated rotating shaft, rotary cutter, centrifugal fan blade, hammer mill hammer leaf, and package assembly forms.Described driving force can be that power such as electric power, fuel oil or combustion gas provide.Technical characterstic is: at the barrel-shaped sieve in the built-in garden of volute housing, barrel-shaped sieve center, garden is provided with a power-actuated rotating shaft, vertically be equipped with by the equally distributed rotary cutter of circumference, centrifugal fan blade, hammer mill hammer leaf with rotation on the rotating shaft, perpendicular with the cutting plane and the rotation that form rotation.For example can evenly distribute and make three or four or five or the more cutting knife, fan blade, hammer leaf etc. of multi-disc by circumference.

Feed described in the utility model combines in broken, separation and finishes with the straw cracker with feeding, this feed is simple with the straw mill structure, dependable performance, and cost is low, is worth of widely use.

Four. description of drawings

Feed described in the utility model has a width of cloth with the accompanying drawing of straw cracker.Wherein:

Fig. 1 is a feed straw mill structure schematic diagram;

In the drawings: 1. volute housing; 2. the barrel-shaped sieve in garden; 3. centrifugal fan blade; 4. rotary cutter; 5. hammer mill hammer leaf; 6. a power-actuated rotating shaft.

Five. embodiment

Embodiment one. feed straw cracker

This routine feed straw cracker, its concrete structure is illustrated by Fig. 1, shown in this example is a kind of feed straw cracker, it includes volute housing 1, the barrel-shaped sieve 2 in garden, power-actuated rotating shaft 6, three rotary cuttves 4, three centrifugal fan blades 3, three hammer mill hammer leaves 5, package assembly forms, and its charging aperture is located on barrel-shaped sieve 2 discs in garden by known technology and is the mouth perpendicular to drawing.These routine straw cracker characteristics are: at the barrel-shaped sieve 2 in volute housing 1 built-in garden, barrel-shaped sieve 2 centers, garden are provided with a rotating shaft 6, vertically be equipped with by circumference with rotation on the rotating shaft 6 and be uniform-distribution with each rotary cutter 4, centrifugal fan blade 3, hammer mill hammer leaf 5 of three, perpendicular with the cutting plane and the rotation that form rotation.When power-actuated rotating shaft 6 drive the rotary cutter 4, centrifugal fan blade 3 of dress on the axle 6, when hammer mill hammer leaf 5 rotates together, cutting knife 4 cuts off straw earlier, by hammer leaf 5 it is pulverized again, blow out outside the volute housing after last materials by 3 fragmentations of fan blade are crossed the barrel-shaped sieve 2 in garden.This routine feed combines in fragmentation, separation and feeding in the same volute housing 1 with the straw cracker and finishes.This straw mill structure is simple, dependable performance, and cost is low.

Embodiment two. feed straw cracker

This routine feed straw cracker, its general structure is illustrated by Fig. 1, this routine feed with different among straw cracker and the embodiment one be that its cutting knife 4, fan blade 3, hammer leaf 5 evenly is scattered in four or five or multi-disc more by circumference.What all the other were not stated is same as described in the embodiment one entirely, no longer having stated more.

Claims

1. feed straw cracker, it includes volute housing, the barrel-shaped sieve in garden, power-actuated rotating shaft, rotary cutter, centrifugal fan blade, hammer mill hammer leaf, package assembly forms, be characterised in that: at the barrel-shaped sieve in the built-in garden of volute housing, barrel-shaped sieve center, garden is provided with a rotating shaft, vertically is equipped with by the equally distributed rotary cutter of circumference, centrifugal fan blade, hammer mill hammer leaf with rotation on the rotating shaft.
