Abstract

The utility model discloses a hammer recrusher for crushing barks peeled from woods. A bark inlet is arranged at the upper part of an engine base, and a cylindrical rotor assembly is fixed on the engine base. A head board is arranged between the bark inlet and the rotor assembly and fixed on the engine base. A bed knife forms a sawtooth shape and is fixed on the engine base. A long hammer and a short hammer are fixed on the outer surface of the rotor assembly, the long hammer and the short hammer are respectively arranged in a staggered and spaced way along the horizontal circumference direction and the longitudinal shaft direction of the rotor assembly, and the sawtooth end of the bed knife corresponds to the outer end of the long hammer. The recrusher breaks, crushes and loosens barks, has good cutting effect, avoids bark winding and blocking phenomena and improves work efficiency.

Description

A kind of hog that is used for the bark pulverizing

Technical field

The utility model relates to a kind of hog, and the bark that strips down on the timber is carried out break process.

Background technology

In industrial processes such as wood-based plate, papermaking, generally contain the bark about 10% in the employed raw material.Fiber content is low in the bark, and during making sheet, bark can influence attractive in appearance at the plate face, can influence intensity, dimensional stability and the resistance to water of product in plate; During papermaking, bark can influence the color and luster of paper and increase the consumption of chemicals; Therefore, need carry out peeling to trees handles.The bark longitudinal fiber of the seeds that have is longer, and toughness is better, at present, generally adopts cutter to cut or the mode of hammering is handled bark, and the mode that cutter is cut is easily cut off bark, is easy to generate winding, clogging during equipment work; The mode of hammering can't be cut off bark effectively, has influence on the utilization again of bark.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of hog that can shred bark effectively, obtain fragment of uniform size is provided.

The technical solution adopted in the utility model is: the bark inlet is arranged on the top of support, fixed cylinder shape rotor assembly on the support, front apron is between bark inlet and rotor assembly and be fixed on the support, bed plate indentation and being fixed on the support, fixed length tup and short tup on the outer surface of rotor assembly, long tup and short tup are along the lateral circumferential direction of rotor assembly and y direction is interlaced with each other respectively is spaced, and the sawtooth end of bed plate is corresponding with the outer end of long tup.

Lateral circumferential direction along rotor assembly is provided with roll flute plate, screen cloth and broken again cutter, and the roll flute plate is fixed in the below of bed plate, the rear portion fixed grit of roll flute plate, and broken again cutter is fixed at the rear portion of screen cloth; The surface distributed roll flute of roll flute plate.

The utility model evacuates bark at the characteristics that bark twines easily, utilizes the high speed rotation of long and short tup, makes bark fracture and broken; The fragmentation to bark has been strengthened in shearing between bed plate and the long tup; The roll flute plate makes bark further refinement under the rubbing effect of roll flute and long tup; The bark of screen cloth after to fragmentation sieves.Shear effect is good, has avoided the winding and the obstruction of bark, has improved operating efficiency.

Description of drawings

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Among the figure: 1. support; 2. front apron; 3. bed plate; 4. roll flute plate; 5. rotor assembly; 6. screen cloth; 7. broken again cutter; 8. long tup; 9. lack tup.

The specific embodiment

As shown in Figure 1, 2, the inlet of bark is arranged on the top of support 1, the cylindrical rotor assembly 5 of fixing rotation on support 1, and front apron 2 is between the inlet of bark and rotor assembly 5 and be fixed on the support 1, and front apron 2 bears the impact of bark.Bed plate 3 is fixedly connected on the support 1 by the bed plate assembly, bed plate 3 indentations.On the outer surface of rotor assembly 5, be fixed with long tup 8 and short tup 9, long tup 8 and short tup 9 are along interlaced with each other being spaced of circumferencial direction of rotor assembly 5 cross sections, be spaced the shock loading in the time of to reduce hammering along rotor assembly 5 y directions are also interlaced with each other.The corresponding formation with the outer end of long tup 8 of the sawtooth end of bed plate 3 is sheared and is paid, and the less gap of leaving between the two is for shearing the gap of bark, can control gap between bed plate 3 and the long tup 8 by device for installing and adjusting.After this structure makes bark through inlet, under the assistance of front apron 2, rotor assembly 5 rotation at a high speed, bark enters the gap between long tup 8 and the bed plate 3, is broken under the shear action of long tup 8 and bed plate 3.Short tup 9 can be eliminated rotor assembly 5 cutting dead angle in the longitudinal direction, guarantees in the effective hammering of whole charging width to raw material.

Be fixed with roll flute plate 4 below bed plate 3, at the rear portion of roll flute plate 4 fixed grit 6, fixing cutting transverse slat on the screen cloth 6 is at the fixing broken again cutter 7 in the rear portion of screen cloth 6.Described roll flute plate 4, screen cloth 6 and broken again cutter 7 are all along the circumferencial direction of rotor assembly 5, be provided with towards rotor assembly 5 positions.The surface distributed of roll flute plate 4 has roll flute, bark is after the gap between long tup 8 and the bed plate 3 is broken, when dropping on the roll flute face of roll flute plate 4, the broad bark is further broken under the effect of the roll flute of long tup 8 and roll flute plate 4, the transverse slat cutting of broken bark on screen cloth 6 sieved discharge to the bark after the fragmentation simultaneously; Bigger bark is avoided bark to follow rotor assembly 5 and is entered the next cutting cycle through broken cutter 7 is broken once more again, and this structure can have been avoided the winding and the obstruction of bark effectively with the bark chopping.
