Problems solved by technology
[0004] As the scale of production enterprises increases, drum chippers with large production capacity are required. The driving power of the existing motor is directly proportional to the production capacity. However, when the power of the motor exceeds 315kW, a high-voltage motor is required. The conditions for high-voltage electricity are not available, which causes difficulties in production in these occasions; even if the conditions for installing high-voltage motors are met, the cost of using high-voltage motors is relatively high

Embodiment Construction
[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0027] Such as figure 1 and figure 2 As shown, the driving principle of the dual-motor drum chipper given in the figure is:
[0028] The low-voltage driving motors 130, 230 drive the small pulleys 120, 220 to rotate through the shaft couplings 121, 221, and the belts 122, 222 are respectively sleeved on the small pulleys 120, 220 and the large pulleys 100, 200, and the driving motors 130, 230 rotate. Shafts 121, 221, small pulleys 120, 220, belts 122, 222, large pulleys 100, 200 drive the main shaft 50 to rotate, and drive the cutter drum 60 to rotate synchronously from both ends.
[0029] Such as image 3 and Figure 4 As shown, a main shaft 50 is installed at the center of the knife drum 60, and both ends of the main shaft 50 protrude from ...

The invention discloses a method for increasing the output power of a drum chipper and a dual motor drive drum chipper. A knife drum is installed on a main shaft; a large belt pulley is installed at each end of the main shaft; a steel frame base is installed on each side of the knife drum; then two low-voltage drive motors are respectively installed on the two steel frame bases; the output shaft of each low-voltage drive motor is connected with a small belt pulley; power is transmitted through belts between the small belt pulleys and the corresponding large belt pulleys; when the two low-voltage drive motors are synchronously started, the small belt pulleys drive the large belt pulleys through the belts; and the two large belt pulleys synchronously drive the knife drum to rotate. The drum chipper has the advantages that the two low-voltage drive motors are adopted to drive the knife drum to rotate, the productivity of the drum chipper is equal to that of a large chipping machine adopting high-voltage motors, the drum chipper can be utilized in a condition that no high tension electricity exists and has high universality, the cost is effectively saved, the mode of driving at two ends of the main shaft is adopted, the stress state of the main shaft and a bearing is improved, and the service life of the main shaft is effectively prolonged.
Description
technical field [0001] The invention relates to a drum-type chipper for chipping logs, in particular to a method for increasing the output power of the drum-type chipper and a dual-motor-driven drum-type chipper, which allows users to operate without a high-voltage power supply. Under the circumstances, the production capacity has been greatly improved. Background technique [0002] Drum chipper is a special equipment for preparing wood chips, widely used in paper mills, particleboard factories, fiberboard factories and wood chip production bases. The drum chipper can cut logs, branches, small diameter wood, etc. into industrial wood chips of certain specifications; the drum chipper is composed of a frame, a knife drum, a feed roller group, a casing, an electric control system, etc. The overall structure is compact and reasonable, the operation is simple, the production capacity is large, and the raw material adaptability is strong. It is an ideal equipment for producing hi...
