Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
As depicted in figs. 1 and 2, the driving principle of the bi-motor drum chipper provided in figure is:
Low-voltage driving motor 130,230 drives small belt pulley 120,220 to rotate by shaft coupling 121,221, belt 122,222 is enclosed within small belt pulley 120,220 and big belt pulley 100,200 respectively, drive motors 130,230 rotates, by shaft coupling 121,221, small belt pulley 120,220, belt 122,222, big belt pulley 100,200 drives main shaft 50 to rotate, and synchronously drives from two ends cutter drum 60 to rotate.
As shown in Figure 3 and Figure 4, in cutter drum 60 center, main shaft 50 is installed, main shaft 50 two ends are stretched out from cutter drum 60, its extension is set with expansion set 111,211, bearing in bearing block 110,210 is arranged on main shaft 50 respectively by expansion set 111,211, and main shaft 50 two ends are supported on support 61 from bearing block 110,210.
Big belt pulley 100,200 respectively key is located at main shaft 50 two ends, be provided with drive motors 130,230 to cutter drum 60 bilateral symmetry, this drive motors 130,230 is 250kW low voltage motor, its drive motors 130,230 output shaft is connected with belt lace wheel shaft respectively by shaft coupling 121,221, and cuticle tape spool is built respectively small belt pulley 120,220; Belt 122 is around small belt pulley 120 with on big belt pulley 100, and belt 222 is around on small belt pulley 220 and big belt pulley 200.
As shown in Figure 5 and Figure 6, steelframe pedestal 240 and steelframe pedestal 140 symmetry are arranged on outside cutter drum 60 two ends; The support 141 that steelframe pedestal 140 comprises upper end and the pedestal 142 be arranged on below support 141, pedestal 142 and ground fix, drive motors 130 is arranged on support 141, can there is relative displacement with pedestal 142 by tensioning bolt 143 in support 141, thus reach tensioning or unclamp the object of belt 122.
The support 241 that steelframe pedestal 240 comprises upper end and the pedestal 242 be arranged on below support 241, pedestal 242 and ground fix, drive motors 230 is arranged on support 241, can there is relative displacement with pedestal 242 by tensioning bolt 243 in support 241, thus reach tensioning or unclamp the object of belt 222.
When actual operation, two drive motors 130,230 of cutter drum 60 both sides operate simultaneously and drive small belt pulley 120,220, small belt pulley 120,220 drives big belt pulley 100,200 to rotate respectively by belt 122,222, and rotation direction as illustrated by the arrows in fig. 1; The synchronous drive shaft 50 of big belt pulley 100,200 is rotated, thus band moving knife drum 60 rotates.
Timber enters from the feeding roller 301 of supply transmission system 300 side of equipment, after the feedstock direction adjusting timber and angle, enters cutter drum 60 and cuts by balance staff 302.
Because the present invention adopts drive motors 130,230 symmetry of two 250kW to drive, theoretical power output can reach 250 × 2=500W, does not need high-voltage motor to reach high-power output, can meet the demand of large-scale Cutting machine to power output; The present invention can use in the various occasion of high voltage source that cannot provide, and is adapted at all kinds of occasion and uses, have very strong versatility.
Moreover owing to adopting the symmetrical mode drive shaft driven, the torsional forces size and Orientation that main shaft 50 is subject to is comparatively even, and bending or distortion not easily occur main shaft 50, effectively carry the service life extending whole wood chipping equipment.
Moreover the cost using two 250W drive motors to consume uses the cost of high-voltage motor under same condition, economical and practical in the middle of the production of reality.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
