Abstract

The rotor type barking machine as one forestry machine has simplified structure and high barking effect. It has one box, and two rotor type barking rollers with arced barking cutters. Two rollers rotate in opposite directions, so that the arced barking cutters generate throwing, friction and other effects to bark while moving axially. The present invention may be used in barking logs of diameter over 30 mm, including curved and irregular timber. The present invention has the features of high barking efficiency, good barking effect and no damage to timber.

Description

Rotor type barking machine

Technical field

The invention belongs to the forestry machinery field, mainly relate to a kind of rotor type barking machine that can divest all size timber bark.

Background technology

Divesting the bark on the timber, is that timber processing is with the required raw-material important procedure of industries such as papermaking.Because treating the timber of bark not exclusively is material straight and circle, also has irregular or crooked material, its difficulty of peeling off bark is bigger.Chinese patent has a kind of bark mill, and this bark mill is formed equidirectional rotation by one high and one low two groups, multistage rotatable parts (roller).Every section rotatable parts all have an inclination angle with horizontal plane, help timber and move forward.The outer surface of rotatable parts is provided with scalping blade, and timber, is peeled off the bark on the timber by the rotation and the friction of rotatable parts at rotatable parts and above the scalping blade.Because timber is that inclination by rotatable parts realizes this mobile above bark mill, is subjected to timber piling height, the variform influence, its speed that moves, the time that contacts with rotatable parts are all inequality; Because two groups of equidirectional rotations of rotatable parts, the stress of timber also has nothing in common with each other, so all directly have influence on the effect of bark.Rotatable parts of Qing Xieing in addition, its transmission mechanism stressed also uneven will directly influence the service life of equipment.

Summary of the invention

The purpose of this invention is to provide a kind of rotor type barking machine, this machine makes timber evenly stressed in the above under the promotion and friction of roller and blade, and orderly moves, and reaches the desirable effect of peeling off bark.

The present invention is achieved by the following measures.Mainly form by base, casing, rotator type roller, bark knife, driving mechanism, guard shield and belt conveyor etc.It is characterized in that: in the casing of bar shaped, level is set side by side with two roots rotor formula bark rollers; Evenly be provided with number row's arc bark knives on each bark roller, each bark knife is α with angle perpendicular to the plane of bark roll axis; Between every adjacent two row's bark knives, bark knife does not laterally overlap, and is crisscross arranged successively on each roller; Bark knife position between two rollers vertically overlaps each other, and is crisscross arranged.In casing two bark rollers above, a baffle plate respectively is set, two baffle plate lower ends are provided with the broach shape strip gab that can allow bark knife to pass through near the position of bark knives.On the casing above the feed end peeling rollers, be provided with charging hopper.Drive unit drives two rollers with opposite direction rotation, and promptly the bark knife of two roller tops rotates to the direction of baffle plate respectively.

According to the needs of different timber, 4-12 row bark knife can be set on the bark roller; Each bark knife is the 1-8 degree with angle α perpendicular to the plane of bark roll axis; Bark knife is an arc, on the knife face of arc, is processed with groove or studs with cutter tooth.

According to the needs of bark operation, in casing, can be provided with a roots rotor formula bark roller.Bark roller folk prescription is to rotation, and other structure is identical with two roller bark mills.

During bark mill work, drive unit (can be driven by two cover drive units) drives the rotation of bark roller, and the timber by charging hopper is packed under the effect of the arc bark knife axial thrust that the inclination angle is arranged, from bottom to top successively moves forward.Groove on the curved knife or inserted bark is peeled off gradually.On the belt conveyor of the bark of peeling off below roller is fallen in the slit of strip broach and bark knife, entruck and carry away through the belt conveyor of feeding end.Peel off the timber behind the bark, belt conveyor output through the discharging opening place.

The invention has the beneficial effects as follows, the peeling operation of bark mill is to promote timber by the axial force that bark knife rotation with angle produces to move forward, so be put into timber on the roller from charging hopper, begin from lower floor, under the promotion of bark knife, move forward layer by layer and peel off, make the traveling time of timber on roller even, peel off the effective of bark.Timber is orderly irregular movement on roller in addition, and for the bark of crooked and irregular timber, the microcephaly all can peel off preferably greater than the bark more than 30 millimeters.

Description of drawings

Fig. 1 is a structural representation of the present invention, and Fig. 2 is the cutaway view of Fig. 1, and Fig. 3, Fig. 4 are the groove and the inserted schematic diagram of arc bark knife, and Fig. 5 is that drive unit schematic diagram, Fig. 6 of two roller bark mills is the drive unit schematic diagram of single roller bark mill.Among the figure 1 be drive unit, 2 for charging hopper, 3 for guard shield, 4 for casing, 5 for the bark roller, 6 for bark knife, 7 for belt conveyor, 8 for base, 9,10 for the bark conveyer, 11 for baffle plate, 12 for broach shape opening, 13 for groove, 14 for inserted, 15 for gear drive, 16 for chain gear transmission, 17 for reductor, 18 for motor, 19 for belt transmission; α among Fig. 1 is a bark knife and angle, arrow perpendicular to the plane of bark roll axis is the traffic direction of belt conveyor; Arrow among Fig. 2 is the direction of rotation of bark roller.

The specific embodiment

Below in conjunction with description of drawings one embodiment of the present of invention.Bark mill mainly is made up of base 8, casing 4, rotator type roller 5, bark knife 6, driving mechanism 1, guard shield 3 and belt conveyor etc.In the casing 4 of bar shaped, level is set side by side with two roots rotor formula bark rollers 5; Evenly be provided with eight row's arc bark knives 6 on each bark roller, on the knife face of bark knife arc, be processed with groove 13; Each bark knife 6 is 3 degree with angle α perpendicular to the plane of bark roller 5 axis; Between every adjacent two row's bark knives 6, bark knife does not laterally overlap, and is crisscross arranged successively on each roller 5; The position of the bark knife 6 between two rollers 5 overlaps each other, and vertically is crisscross arranged.Above casing 4 interior two bark rollers 5, the position of 11, two baffle plate 11 lower ends of a baffle plate near bark knife 6 respectively is set, be provided with the broach shape strip gab 12 that can allow bark knife to pass through.On the casing above the feed end peeling rollers, be provided with charging hopper 2.Drive unit drives two rollers with opposite direction rotation, and promptly the bark knife of roller top is to the direction rotation of baffle plate.

8 row's bark knives 6 are arranged on the bark roller 5 of bark mill of the present invention, and thickness is 20 millimeters; Each bark knife is that α is 3 degree with angle perpendicular to the plane of bark roll axis; Bark knife 6 is an arc, on the knife face of arc, is processed with groove 13.

Bark mill drives two bark rollers 5 with opposite direction rotary work by motor 18, belt transmission 19, reductor 17, chain gear transmission 16 and gear drive 15, and promptly the bark knife of two roller tops rotates to the direction of baffle plate respectively.The timber of packing into by charging hopper 2, under the promotion of arc bark knife 6 axial forces that the inclination angle is arranged, successively moving forward from bottom to top.Groove 13 on the curved knife is peeled off bark gradually.On the belt conveyor 9 of the bark of peeling off below roller is fallen in the slit of strip broach and bark knife, entruck and carry away through the belt conveyor 10 of feeding end.Peel off the timber behind the bark, belt conveyor 7 outputs through the discharging opening place.
