Summary of the invention

The object of this invention is to provide improving one's methods of a kind of special-purpose log splitter, solved that existing log splitter working (machining) efficiency is low, range of work limitation and the high problem of equipment failure rate.

In order to achieve the above object, the present invention by the following technical solutions.

Improving one's methods of a kind of special-purpose log splitter, comprise the following steps: the feed system of a, log splitter changes carrier bar into and carries, and increase up and assist carrier bar mechanism, carrier bar inner sprocket moves on under feeding drum, realize feeding function with the synergy of feeding roller, remove lower feeding roller.

In b, log splitter feed system, use under the replacement of carrier bar inner sprocket " pendulum ", upper " pendulum " is that the single cylindrical roller that diameter is larger substitutes, and its quality is large and surperficial with bastard.

C, the integral knife blade that existing log splitter is run through to total length change a plurality of fly cuttves into, along rotor circumference and axis direction, are all uniformly distributed.

Beneficial effect of the present invention: after improving according to this method, equipment processing ability strengthens, and material does not need to pick classification, seldom occurs solid accumulation phenomenon, reduces workman's labour intensity; The good combination property of equipment, stable working, reduces vibration and noise greatly, has reduced equipment failure rate; Working (machining) efficiency is high, compares improve working (machining) efficiency more than 2 times with same specification common apparatus.

In figure, 1, input carrier bar, 2, auxiliary carrier bar, 3, feeding roller, 4, fixed blade, 5, rotate rotor, 6, circular screen mesh, 7, output belt.

The specific embodiment

Below in conjunction with accompanying drawing, the present invention is described further.

Improving one's methods of a kind of special-purpose log splitter, comprises the following steps: the feed system of a, log splitter changes carrier bar into by original Belt Conveying and carries, and increases up auxiliary carrier bar 1 mechanism, makes material evenly input spout; Carrier bar inner sprocket moves on under feeding drum, realizes feeding function with 3 synergy of feeding roller, removes lower feeding roller, greatly reduces manufacturing cost.

B, the traditional disintegrating machine feed system of timber adopt " pendulum " formula mechanism conventionally, under " pendulum " maintain static, upper " pendulum " can swing up and down around fixed axis, material size variation is swallowed in adaptation, its pivot angle size is controlled by hydraulic system; General upper and lower " pendulum " a plurality of little rollers that all distribute, trees rhizome, branch are inserted between adjacent rollers, easily block roller, make rotatable parts stall, burn out motor; In structure after improvement, use under the replacement of carrier bar inner sprocket " pendulum ", upper " pendulum " is that the single cylindrical roller that diameter is larger substitutes, and its quality is large and surperficial with bastard, can compress material raising and swallow ability, also can be not stuck by material.When material is larger, cylinder can upwards float, and adapts to the range of work and changes.

C, existing log splitter adopt 2 to 4 integral knife blade that run through total length to be embedded on rotor circumference, and the rotor face of cylinder need to be outputed skewed slot and make chip pocket, rotor mass unbalance, and during High Rotation Speed, greatly, noise is high in vibration; Because be integral knife blade, cutting edge is long, cutting force is large, interrupted cut more can cause process system vibration, and smear metal is strip, increases the difficulty of second-time breakage, in new design, change integral knife blade into a plurality of fly cuttves, along rotor circumference and axis direction, be all uniformly distributed, be equivalent to cutter continuous cutting, system is stressed evenly; The cutting edge inclination that increases cutter, makes the sharper cutting of cutter more steady, and smear metal becomes isometric segment, improves crushing effect.

Fig. 1 is this log splitter fundamental diagram, whole equipment is by input system, feed system, system of processing, output system and composition of the control system, main parts size comprises input carrier bar 1, auxiliary carrier bar 2, feeding roller 3, fixed blade 4, rotate rotor 5, circular screen mesh 6, output belt 7 and hydraulic cylinder, electrical control cubicles etc., during use, material to be broken is placed on feeding input carrier bar 1, belt for scraper chain animal material moves to processing district, auxiliary carrier bar 2 with input between carrier bar 1 at an angle, leave the gap that allows material to pass through, different from the two direction of motion of material contact position, its effect is that material is spread out and made it evenly enter processing district, prevent that solid accumulation from cannot enter at feeding entrance, if solid accumulation is too high on input carrier bar 1, auxiliary carrier bar 2 can be stirred the raised area backward, wait for bottom material by after enter again spout, feeding roller 3 and the 1 inner sprocket mating reaction of input carrier bar, the rotation direction of feeding drum is contrary with input carrier bar 1 sprocket wheel, material can be forced to push processing district, and feeding roller 3 also can move along vertical, while entering the material size variation of spout, feeding roller 3 can fluctuate, feeding roller 3 is slowed down or balance by auxiliary hydraulic system, and during feeding bulk materials, feeding roller 3 promotes flexibly, and has worked as part processing, and when feeding drum falls, the elements such as oil cylinder and accumulator just play cushioning effect, make it motion steadily to reduce to impact, when maintenance, replacing cutter, hydraulic cylinder can be lifted feeding roller 3 etc., the material that enters processing district is subject to rotating cutting, the shock of a plurality of fly cuttves on rotor 5, become small volume billet and fall into the cavity between rotor and circular screen mesh 6, volume the greater also can roll, rub, collides between cutter and screen cloth, become more fine grained chippings and spilt by sieve screen apertures, finally by 7 outputs of output belt.
