Description

Bucket wheel mechanism and bucket wheel type digging and loading machine Technical Field The utility model relates to the technical field of engineering machinery, in particular to a bucket wheel mechanism and a bucket wheel type digging and loading machine. Background The bucket-wheel mechanism is one of important components on the bucket-wheel stacker reclaimer, and has the function of realizing the material taking and loading machine through rotary motion, and can generally comprise a bucket wheel and a driving device thereof. The existing bucket wheel driving mode mainly comprises two modes, namely motor and speed reducer driving and low-speed high-torque motor direct driving, wherein the low-speed high-torque motor is mainly used for bucket wheel equipment with relatively smaller torque requirements due to torque limitation, and the motor and speed reducer driving and the low-speed high-torque motor driving are arranged on the outer side of a bucket wheel arm frame and far away from the bucket wheel end. In the motor and speed reducer mode, the motor is a three-phase asynchronous motor, the speed reducer is a cylindrical gear speed reducer, the volume and the mass of the motor and the speed reducer are relatively heavy, and the stability of the bucket wheel machine is also unfavorable. Disclosure of utility model The utility model aims to provide a bucket wheel mechanism and a bucket wheel type digging machine, which solve the problem of overlong axial dimension of a bucket wheel shaft and improve the stability of the whole machine. The bucket wheel mechanism comprises a bucket wheel, a bucket wheel arm support, a bucket wheel shaft, a traveling speed reducer, a hydraulic motor and a hydraulic motor, wherein the bucket wheel arm is arranged on the bucket wheel arm support, the bucket wheel shaft is rotatably arranged on the bucket wheel arm, one end of the bucket wheel shaft is connected with the bucket wheel through a connecting piece, the traveling speed reducer is embedded at one end, far away from the bucket wheel, of the bucket wheel shaft, the traveling speed reducer is connected with the bucket wheel arm through a transition sleeve, and the hydraulic motor is inserted on the traveling speed reducer, and the end face of the output end of the traveling speed reducer is connected with the bucket wheel shaft. Further, the bucket wheel shaft is of a hollow step shaft structure, the walking speed reducer is embedded in a cavity of one end, far away from the bucket wheel, of the bucket wheel shaft, and the end face, far away from one end of the bucket wheel, of the bucket wheel shaft is connected with the end face of the output end of the walking speed reducer. The bucket wheel arm comprises a hollow sleeve, a first mounting support, a second mounting support and a second mounting support, wherein the hollow sleeve is arranged on the bucket wheel arm support, the first mounting support is arranged in the hollow sleeve, the second mounting support is arranged in the hollow sleeve, and the bucket wheel shaft is movably connected in the first mounting support and the second mounting support through bearings. Further, the bucket wheel arm further comprises a right connecting plate, wherein the right connecting plate is arranged at one end, adjacent to the walking speed reducer, of the hollow sleeve, and the right connecting plate is used for installing the transition sleeve. Further, the bucket wheel arm further comprises a left connecting plate, wherein the left connecting plate is arranged at the other end of the hollow sleeve, and a bracket for installing a framework oil seal is arranged on the left connecting plate. Further, a framework oil seal is arranged between the right connecting plate and the bucket wheel shaft. Further, an oiling device for bearing lubrication is arranged on the hollow sleeve. Further, the connecting piece adopts an expansion sleeve. Furthermore, the hydraulic motor is inserted into the walking speed reducer by adopting flange connection. A bucket wheel type digging machine, wherein the bucket wheel mechanism is arranged on the bucket wheel type digging machine. Compared with the prior art, the utility model has the following beneficial effects: 1. The walking speed reducer and the hydraulic motor are adopted to replace the traditional cylindrical gear speed reducer and the three-phase asynchronous motor respectively, the hydraulic motor is directly inserted on the walking speed reducer, the walking speed reducer has the advantage of compact structure, and the serial parts are changed into embedded parts, so that the axial size is obviously shortened. 2. The weight of the front end of the bucket wheel arm can be reduced, so that the stability of the whole machine is improved.
