Cleaning roller device and beach cleaning vehicle with the device

Abstract

The invention discloses a cleaning rolling wheel device and a sandbeach cleaning vehicle with the same. The cleaning rolling wheel device comprises a cleaning rolling wheel and a fixing frame thereof. One end of the cleaning rolling wheel is connected with the cleaning rolling wheel fixing frame through an insert bearing with housing, the other end of the cleaning rolling wheel is connected with an output shaft of a driving device through a flexible coupling, and the driving device is fixed on the cleaning rolling wheel fixing frame. The structural characteristic that the insert bearing with housing and the flexible coupling can bear radial force and compensate radial and axial displacement besides transmitting torque is utilized to achieve the goal of shortening the supporting connecting lengths of two ends of the cleaning rolling wheel, rigidity of the cleaning rolling wheel is enhanced, coaxiality of bearings at two ends of the cleaning rolling wheel is guaranteed, the bearings and an output shaft of a hydraulic motor are protected better, use safety is improved, service lives of the bearings and the output shaft of the hydraulic motor are prolonged, the effective working length of the cleaning rolling wheel is also increased, the sweeping area is increased, and sweeping working efficiency is improved. Processing precision of the cleaning rolling wheel fixing frame can be reduced.

Description

technical field [0001] The invention relates to a beach cleaning vehicle, in particular to a cleaning roller device and a beach cleaning vehicle with the cleaning roller device. Background technique [0002] One of the key components of the garbage pickup device of the beach cleaning vehicle is the cleaning roller device. Its structural feature is that the length of the cleaning roller is close to the width of the car body. At present, the two ends of the cleaning roller are generally fixed and supported by ordinary deep groove ball bearings, driven by a hydraulic motor. The hydraulic motor and the roller are connected by pin type or plum blossom type rigid coupling. This kind of cleaning roller device has the following limitations: On the one hand, the pin type or plum blossom type rigid coupling can only transmit torque and cannot bear radial force, so the hydraulic motor and the two ends of the roller connected to it must be installed on the On the roller bracket, the tw...

AI Technical Summary

Problems solved by technology

This kind of cleaning roller device has the following limitations: On the one hand, the pin type or plum blossom type rigid coupling can only transmit torque and cannot bear radial force, so the hydraulic motor and the two ends of the roller connected to it must be installed on the On the roller bracket, the two are connected by a semi-rigid coupling, so the installation length occupied is relatively large, and the effective length of the cleaning roller is reduced

On the other hand, limited by its structure and installation space, the span supported at both ends of the cleaning roller is long and the rigidity is poor. Therefore, during the operation, when the road surface is uneven, the horizontal roller will produce Large deflection, resulting in misalignment of the bearings at both ends, causing premature damage to the bearings, and even damage to the coupling and hydraulic motor shaft in severe cases, and the dust-proof sealing rings that come with the bearings are easily damaged during operation
