During the long-term operation of the hydraulic motor, the temperature of the outer wall of the hydraulic motor is too high, which affects the service life of the hydraulic motor. Long-term high-temperature operation easily leads to component aging and shortens the service life. At the same time, the heat on the outer wall of the motor cannot be effectively recovered and utilized. Summary of the Invention

It is convenient for the installation seat to dissipate heat from the motor body through the heat dissipation blocks. And on the opposite surface of the protection partition and the heat dissipation block, there is a cleaning brush on the inner wall of the protection partition. The cleaning brush fits with the dust-proof net on the surface of the heat dissipation block. Thus, it is convenient to clean the heat dissipation block through the protection partition.

One end of the cleaning brush is provided with a dustproof net on the surface of the heat dissipation block. The cleaning brush fits with the dustproof net. A heat dissipation mechanism is provided inside the heat dissipation block, and the heat dissipation mechanism includes a heat dissipation fan and a rotating motor.

[0014] Advantages of the present invention: For this hydraulic drive motor device, when the temperature of the motor body rises, the operation panel drives the first lead screw to rotate through the cooperation of the servo motor and the transmission rod. The first lead screw meshes with the two protective partitions, so as to drive the two protective partitions to displace on one side of the mounting seat through the first lead screw. When the protective partitions are opened, the heat dissipation block is started, so that the mounting seat can dissipate heat from the motor body through the heat dissipation block. And on the opposite surface of the protective partition and the heat dissipation block, a cleaning brush is provided on the inner wall of the protective partition. The cleaning brush fits with the dustproof net on the surface of the heat dissipation block, so as to facilitate the cleaning of the heat dissipation block through the protective partition.
