Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-Figure 5 The hydraulic motor assembly travel drive device shown is used to assemble the hydraulic motor body 1, which includes a mounting support box body 2 and a travel reducer 3. The output shaft of the hydraulic motor body 1 and the input shaft of the travel reducer 3 are connected together in the mounting support box body 2 (not shown in the figure). By setting the mounting support box body 2, the hydraulic motor body 1 and the travel reducer 3 are assembled to play a protective role.

[0021] In order to achieve heat dissipation inside the mounting support box body 2, a first circular groove 7 is provided on one side of the support portion 4, a cylinder 8 is fixedly connected to the outer wall of the mounting support box body 2, the cylinder 8 is connected to the first circular groove 7, and a first filter plate 9 is fixedly connected to the end of the cylinder 8 away from the support portion 4, and the first filter plate 9 is provided to prevent impurities from entering the interior of the mounting support box body 2. A support plate 10 is rotatably provided inside the cylinder 8, a first motor 12 is fixedly connected to the support plate 10, a fan blade 13 is fixedly connected to the driving shaft of the first motor 12, and a plurality of fan blades 13 are provided, and the plurality of fan blades 13 are evenly distributed around the driving shaft of the first motor 12. A second circular groove 15 is provided on the other side of the support portion 4, a second filter plate 16 is fixedly connected to the interior of the second circular groove 15, and the second filter plate 16 is provided to prevent impurities from entering the interior of the mounting support box body 2.

[0022] During operation, the first motor 12 drives the fan blades 13 to rotate, and external air enters the mounting support box body 2 through the second circular groove 15 and is discharged through the cylinder 8, thereby realizing air circulation inside the mounting support box body 2 and achieving the effect of heat dissipation.

[0023] Impurities in the external air will accumulate on the second filter plate 16 to achieve a filtering effect and prevent the impurities from entering the interior of the mounting support box body 2.

[0024] However, after long-term use, the accumulation of impurities can easily cause the second filter plate 16 to be blocked, affecting the ventilation and heat dissipation efficiency; at this time, the control support plate 10 is rotated 180°, driving the first motor 12 and the fan blades 13 to rotate, and the external air enters the mounting support box body 2 from the cylinder 8 and is discharged from the second circular groove 15 to blow away the impurities accumulated on the second filter plate 16, achieving the cleaning effect, and the impurities are blown away by the movement of the hydraulic walking device. In this process, even if there are impurities accumulated on the first filter plate 9, they can be cleaned after the support plate 10, the first motor 12, and the fan blades 13 rotate and reset and air is supplied again.

[0025] By arranging structures such as the cylinder 8, the support plate 10, the fan blades 13, the first filter plate 9 and the second filter plate 16, gas circulation inside the mounting support box body 2 is achieved, thereby achieving the effect of protecting and dissipating heat at the connection between the hydraulic motor body 1 and the travel reducer 3, while preventing impurities from entering the interior of the mounting support box body 2 and being able to automatically clean the impurities.

[0027] During specific use, a storage battery may be arranged on the mounting support box body 2 to supply power to the first motor 12 and the second motor 14 .

[0028] A pressure sensor 17 is provided at the second circular groove 15, and the pressure sensor 17 is fixedly connected to the inner wall of the support part 4. Specifically, a controller may be provided to be connected between the pressure sensor 17 and the second motor 14.
