Abstract
The utility model relates to a coaxial excavator which is provided with a walking-type chassis. A control chamber is arranged on the upper portion of the walking-type chassis. A motor is fixedly arranged in front of the upper portion of the chassis, a rotor shaft of the motor is connected with a transmission rod, a transmission shaft sleeve is arranged on the outer portion of the transmission rod in a sleeved mode, the center of the transmission rod is connected with the center of a transmission gear, the transmission gear is in meshed transmission with a driven gear I, the driven gear I is coaxially connected with a driven gear II in a transmission mode, the driven gear II is in meshed transmission with a driven gear III, the center of the driven gear III is arranged on the transmission shaft sleeve in a sleeved mode, the side faces of the transmission shaft sleeve are respectively connected with an earth cutting cutter I through two connecting rods, and the front end of the transmission rod is connected with an earth cutting cutter II. The excavator is stable in operation, sink accidents cannot happen, efficiency of earth cutting is high, a soil layer can be effectively prevented from slanting, and great convenience is brought to earth cutting construction under a mine.
Description
Technical field
The utility model relates to a kind of excavator, especially high the and a kind of coaxial excavator that operates steadily of digging efficiency.
Background technology
At present, it is that the accident of sinking often takes place that known excavator is advanced in soil layer, move not steadily, and digging efficiency is low and often cause cob wall to tilt when cutting the earth, and brings very big inconvenience to underground shoveling.
The utility model content
Low and move jiggly problem in order to overcome existing excavator digging efficiency, the utility model provides a kind of coaxial excavator, this excavator operates steadily when travelling in the tunnel, the accident of sinking can not appear, efficient is higher during shoveling, and can prevent effectively that cob wall from tilting, bring great convenience to cutting the earth under the mine.
The technical scheme that its technical problem that solves the utility model adopts is: this coaxial excavator is provided with a walking chassis, the top on chassis is provided with the control room, the place ahead, top on chassis is fixed with motor, the armature spindle of motor links to each other with drive link, the outer cover of drive link is equipped with driving sleeve, the center of drive link links to each other with the center of travelling gear, travelling gear and driven gear I engaged transmission, the driven gear I is in transmission connection with the driven gear II is coaxial, driven gear II and driven gear III engaged transmission, the center of driven gear III is contained on the driving sleeve, the side of driving sleeve is connecting the earth-digging cutter I respectively by two connecting rods, and the front end of drive link is connecting the earth-digging cutter II.When under mine, cutting the earth, open by control room control motor, the rotation of driven by motor travelling gear, travelling gear drives the rotation of earth-digging cutter II by drive link and cuts the earth, simultaneously, travelling gear drives the rotation of earth-digging cutter I by driven gear I, driven gear II and driven gear III successively and cuts the earth, earth-digging cutter I and earth-digging cutter II co-operation, thus reach the purpose that improves shoveling efficient.
The beneficial effects of the utility model are, this excavator operates steadily, and the accident of sinking can not occur, and efficient is higher during shoveling, and can prevent effectively that cob wall from tilting, and brings great convenience to excavation and construction.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is structural principle schematic diagram of the present utility model.
Among Fig. 1,1. earth-digging cutter I, 2. driven gear II, 3. driven gear I, 4. drive link, 5. motor, 6. control room, 7. chassis, 8. travelling gear, 9. driven gear III, 10. driving sleeve, 11. earth-digging cutter II.
The specific embodiment
In Fig. 1, this coaxial excavator is provided with a walking chassis 7, the top on chassis 7 is provided with control room 6, the place ahead, top on chassis 7 is fixed with motor 5, the armature spindle of motor 5 links to each other with drive link 4, the outer cover of drive link 4 is equipped with driving sleeve 10, the center of drive link 4 links to each other with the center of travelling gear 8, travelling gear 8 and driven gear I 3 engaged transmission, driven gear I 3 and driven gear II 2 coaxial being in transmission connection, driven gear II 2 and driven gear III 9 engaged transmission, the center of driven gear III 9 is contained on the driving sleeve 10, the side of driving sleeve 10 is connecting earth-digging cutter I 1 respectively by two connecting rods, and the front end of drive link 4 is connecting earth-digging cutter II 11.When under mine, cutting the earth, open by control room 6 control motors 5, motor 5 drives travelling gear 8 rotations, travelling gear 8 drives 11 rotations of earth-digging cutter II by drive link 4 and cuts the earth, simultaneously, travelling gear 8 drives 1 rotation of earth-digging cutter I by driven gear I 3, driven gear II 2 and driven gear III 9 successively and cuts the earth, earth-digging cutter I 1 and earth-digging cutter II 11 co-operation, thus reach the purpose that improves shoveling efficient.
