1.Summary,

The drum chipper is the special tools for production of wood chips. Widely used in the preparation section in industrial production of particleboard, fiberboard and paper mills and wood chip production plant. Small drum chipper or factory laboratory preparation of raw materials, the best equipment.

Drum chipper, cutting raw materials trails, timber harvesting residues (branches, twigs, etc.) and wood processing residues of raw materials (skins, crates, logs, cores, waste veneer, etc.), can also be used to cut non-wood raw materials (such as sugar cane, reed, bamboo, etc.).

BX series drum chipper compact structure, reasonable, easy to operate, high production capacity, raw materials, wide adaptability, the cutting chip quality, safe, reliable, easy maintenance, the more advanced a chipper.

2.The main structure

The drum chipper machine seat, knife roll, under the feeder institutions, feeding equipment and hydraulic buffer system and electrical control system.

a. Base

Base made of high strength steel plate welded together, the support base of the machine. The bed knife seat support base welded as one, placed the end of the knife block. The bed knife specializes in the manufacture of high strength bolts through the pressure of the knife block at the end of the knife seat. The bottom tool holder can be drawn through the base wall panels on the side of the hole free, it relies on two folders button fixed in the machine base. Slashing the piece of straw through the sieve holes down, large straw piece by scrap lever mounted on the machine again broken.

b. knife roll

The knife roller drum chipper work. It has good stiffness and moment of inertia, and after the equilibrium experiments.

Spindle and cutter roller locking device or connection. Compact and reasonable structure, easy accessibility, use and reliable. Spindle at both ends by self-aligning roller bearings, bearing fixed on the base.

Knife roller is equipped with two or three throwing knives, using a specially crafted Flying bolt by pressing the knife board knife roller.

c. upper and lower feed institutions

On the feeder institutions (commonly known as "swing") from the previous feed roller, feed roller, feed rollers, pendulum shaft, reducer and other components. Under the feeder institutions by the composition of the feed roller, support roller and the feed shaft reducer.

Larger diameter feed roller, heavy weight, surface with coarse teeth, which can compress the raw materials to make it balanced the speed of the cutting position. To ensure that the length and quality of the chipper. , Under the feed roll teeth staggered, so that the debris cleaning up the.

On the feed roller locking device fastening to the shaft axis spherical roller bearings, bearing fixed to the upper feed roller seat. The upper feed roller through the pendulum shaft mounted on the base, and swing around the axis, in order to ensure that it can automatically adapt to the height of the feed.

The lower feed roller through the locking device fastening to the shaft axis and the support roller by spherical roller bearings, bearing fixed on the base. Deceleration, the motor were driving the upper and lower feed roller. The upper feed roller rotational direction and knife rollers rotating in the same direction, under the feed roller rotation direction of the knife roller rotation in the opposite direction.

d.Feeding Device

The feeding device has a uniform supply of material belt conveyor.

The belt conveyor by the main motor, reducer, trough belt roller. Material objects in the tank by belt conveyor material into the feeder institutions.

e. hydraulic buffer system

In addition to the small drum chipper, large and medium-sized drum chippers have hydraulic cushioning system.

The hydraulic buffer system by the hand pump (or electric pump), the 2113 machine with the size of the pump, one-way throttle valve, accumulator, cut-off valves and other oil components (216,218 machine using only manual pump operation is completed directly).

Fuel supply to the pump can start cover, fuel supply to the pump, can put the set up or reducing its weight through the accumulator accumulator cushion swing frame drop smooth.
