Description
Technical field
The present invention relates to coal-winning machine technical field, particularly relate to a kind of cutting units and there is the coal-winning machine of this cutting units.
Background technology
Coal-winning machine is just towards future development that is high-power, high working face.At present, cutting units has a drive motors and a cylinder driven by this motor, and this drive motors and this cylinder are arranged at the two ends of this cutting units respectively, and the axis of this motor and this cylinder is parallel to each other.As shown in Figure 1, Fig. 1 is the schematic diagram of the inner drive mechanism of existing cutting units.This cutting units is made up of drive motors 9, driving of parallel axes train 8, planet circular system 7 and cylinder 6 etc.Its operating principle is driven by drive motors 9, by the distance transmission of driving of parallel axes train 8, drives this cylinder 6 to rotate to realize cut coal through planet circular system 7 deceleration transmission again.
Adopt the mining operations needs of face reality to meet high working face, the mode adopted at present is the scale increasing cylinder.But, due to the increasing of cylinder, make its manufacture, transport and safeguard difficulty also increase simultaneously.
Therefore, how improving for above-mentioned deficiency, more to adapt to use needs, is those skilled in the art's technical problems urgently to be resolved hurrily.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of cutting units, it comprises cutting units casing and is arranged at the first drum assembly, the second tin roller assembly on this cutting units casing, the first cylinder that described first drum assembly comprises the first drive motors, the first planet train be connected with described first drive motors and is connected with described first planet train, the second tin roller that described second tin roller assembly comprises the second drive motors, the second planet circular system be connected with described second drive motors and is connected with described second planet circular system.
Further, the output shaft of described first drive motors is connected by the power shaft of first clutch with described first planet train, and the output shaft of described first planet train is connected with described first cylinder.
Further, the output shaft of described second drive motors is connected by the power shaft of second clutch with described second planet circular system, and the output shaft of described second planet circular system is connected with described second tin roller.
Further, described first drive motors and described second drive motors are bolted on described cutting units casing.
Cutting units of the present invention two drum assemblies instead of a swift of the prior art, can reduce the size of each drum assembly like this, thus reduce the difficulty manufacturing it, transport and safeguard.
The present invention also provides a kind of coal-winning machine being provided with described cutting units.Because above-mentioned cutting units has above-mentioned technique effect, therefore, the coal-winning machine being provided with this cutting units also has corresponding technique effect.
Accompanying drawing explanation
The accompanying drawing forming a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the inner transmission mechanism of cutting units of the prior art.
Fig. 2 is the front view of cutting units provided by the present invention.
Fig. 3 is the structural representation of the inner transmission mechanism of cutting units provided by the present invention.
Detailed description of the invention
To it should be pointed out that in this part to the description of concrete structure and description order it is only explanation to specific embodiment, should not be considered as there is any restriction to protection scope of the present invention.In addition, when not conflicting, the embodiment in this part and the feature in embodiment can combine mutually.
Refer to Fig. 2 and Fig. 3, the cutting units that the embodiment of the present invention provides comprises cutting units casing 1 and is arranged at the first drum assembly 2, the second tin roller assembly 3 on this cutting units casing 1.This first drum assembly 2 comprises the first drive motors 21, first planet train 22 and the first cylinder 23, and this second tin roller assembly 3 comprises the second drive motors 31, second planet circular system 32 and second tin roller 33.
This first drive motors 21 is arranged on this cutting units casing 1, usually adopts bolt to be connected on this cutting units casing 1 by this first drive motors 21.The power shaft of this first planet train 22 is connected with the output shaft of this first drive motors 21, and the output shaft of this first drive motors 21 adopts first clutch to be connected with this first planet train 22 power shaft usually.When this first cylinder 23 does not need work, first clutch can be placed in out-of-gear state, to facilitate the maintenance of maintenance and equipment.The output shaft of this first planet train 22 is connected with this first cylinder 23, and the moment of torsion that this first drive motors 21 exports is passed to this first cylinder 23 by this first planet train 22, this first cylinder 23 is rotated thus carries out the operation of cut coal.
This second drive motors 31 is arranged on this cutting units casing 1 and also and between this first drive motors 21 is separated with certain distance, to make not interfere between this first cylinder 23 and this second tin roller 33.This second drive motors 31 is connected on this cutting units casing 1 by usual employing bolt.The power shaft of this second planet circular system 32 is connected with the output shaft of this second drive motors 31, and the output shaft of this second drive motors 31 adopts second clutch to be connected with this second planet circular system 32 power shaft usually.When this second tin roller 33 does not need work, second clutch can be placed in out-of-gear state, to facilitate the maintenance of maintenance and equipment.The output shaft of this second planet circular system 32 is connected with this second tin roller 33, and the moment of torsion that this second drive motors 31 exports is passed to this second tin roller 33 by this second planet circular system 32, this second tin roller 33 is rotated thus carries out the operation of cut coal.
Cutting units provided by the present invention is provided with two drum assemblies, instead of a swift of the prior art, the size of each drum assembly can be reduced like this, thus reduce the difficulty it being manufactured, transports and safeguard.
