Abstract

The utility model relates to a disc type short cutter wood piece cutting machine which cuts raw materials, such as log, wood with small dimension and brushwood into woody sheets with certain sizes and technologies. The utility model is used for manufacturing a shaving board, a fibre board and pulp and is mainly composed of a power machine, a speed reduction transmission device, a cutter disc with a short cutter to cut, a material feeing opening, a material discharging opening, a machine base, etc. The utility model is characterized in that a group of a plurality of short cutters with equal width replaces a long cutter; the short cutters are arranged on the cutter disc according to the principle of continuous cutting. The utility model has the advantages of reducing cutting power, reducing the metal capacity of the cutter disc, lowering energy consumption, decreasing the vibration noise of the complete machine and reducing sharpening material of the cutters and material consumption.

Description

Disc type short sword wood chipper

The utility model relates to a kind of disc type short sword wood chipper of balanced cutting, belong to forestry and woodworking machinery technical field, be to be raw material, cut into the technological wood chips of certain specification, be used to make particieboard, fiberboard and paper pulp with log, small dimension wood, brush wood.

Traditional disc type wood chipper is to utilize to be installed in some on the cutting cutterhead strip fly cutter is chopped back into technological wood chips to timber.By literature search, existing disc type wood chipper is all the rimmer knife wood chipping equipment, and as reflections such as Encyclopadia Sinica, mechanical engineering manual, Chinese patent 91224964.1,93247539.6, United States Patent (USP)s 5080153,5094280,5305811 all is this structural shape.Be characterized in that fly cutter is a strip, blade radially or be with certain top rake to be evenly arranged on the cutterhead.Though this wood chipping equipment productivity ratio is higher, but because long fly cutting is whole log end face, required cutting power is very big, particularly to round wood, its cutting is very unbalanced, make the noise and the vibration of complete machine all very big, power peak is big, the chip quality instability, and when wear and tear in rimmer knife certain, wholely must carry out sharpening or replacing to rimmer knife, the tool sharpening amount is big, and material consumption is also big.The tradition wood chipping equipment is vibration, a noise maximum in wood-based plate and the pulping and paper-making process equipment, and working environment is polluted the most serious machine.

The purpose of this utility model is at existing wood chipping equipment above shortcomings part, a kind of balanced cutting that can realize substantially continuously is provided, vibration noise is little, power demand is little, metals capacity is little, power consumption less, the more stable novel disc type short sword wood chipper of chip quality.

The purpose of this utility model is achieved in that provides a kind of disc type short sword wood chipper, it is made up of engine, speed reduction gearing, cutting cutterhead, brake, charging aperture, discharging opening and support, wherein cutting cutterhead is short sword cutting cutterhead, feature is: this cutterhead is made of some groups short sword group, and the short sword of each group is arranged according to helix on cutterhead; And the short sword of each group is made up of some short swords that width is equated; The transverse shape of short sword is trapezoidal.Under actuating unit drove, short sword cuts cutterhead can be from the log of charging aperture input like this, and carrying out one by one is balanced continuously in order cuts, and makes the technological wood chips of certain specification, and wood chip is discharged from discharging opening.

Further specify as follows by drawings and Examples:

Fig. 1 is the utility model general structure sketch.

Wherein: 1 charging aperture, 2 discharging openings, 3 short swords cutting cutterhead, 4 brakes, 5 speed reduction gearings, 6 engines, 7 supports

Fig. 2 respectively organizes the schematic diagram that the short sword blade is arranged in the utility model on cutterhead

Wherein: 8 logs, 9 short swords

Embodiment: according to the structure of disc type short sword wood cutting machine and the specification of Fig. 2, cut the short sword that is furnished with 2 groups of symmetries on the dish, 4 every group at short sword; Requirement according to former size class and productivity ratio is different, also can arrange 3 groups, 4 groups short swords symmetrically on cutterhead, and every group of short sword number also can be 3,5,6, and then requirement group of productivity ratio height number is many, and former size class greatly then requires every group cutter number many.The blade of every group of short sword is all arranged according to helix, and after power reached short sword cutting cutterhead, along with the short sword of cutterhead rotation, promptly the log to the maximum diameter level that entered by charging aperture carried out continuous, balanced cutting.

Advantage of the present utility model:

1. all obviously minimizings of cutting force and cutting power, main cutting force only are common wood chipping equipment About half, cutting power only is about 2/3rds of common wood chipping equipment.

2. the amplitude of vibration and noise decline is bigger, and the hull vibration accekeration only is common cutting About 2/3rds of sheet machine; Workman's parotic noise reduces about 7% than common wood chipping equipment.

3. the qualification rate of wood chip improves about 10% than common wood chipping equipment.

Claims (3)

1. disc type short sword wood chipper, form by engine, speed reduction gearing, brake, cutting cutterhead, charging aperture, discharging opening and support, it is characterized in that: the cutting cutterhead is a short sword cutting cutterhead, it is made of some groups short sword group, the short sword of each group is arranged according to helix on cutterhead, cutting timber that can be continuous, balanced.
2. disc type short sword wood chipper according to claim 1 is characterized in that: each short sword group is made up of some short swords that width is equated.
3. according to claim 1,2 described disc type short sword wood chippers, it is characterized in that: the transverse shape of short sword is trapezoidal.
