[0033] Specifically, such as Figure 4, the front heat sink 301 includes a front cover 301-1 nested on the front side of the gear reducer body 200. The inside of the front cover 301-1 is a hollow structure for storing cold water. Both the upper and lower sides of the front cover 301-1 are fixedly connected with first fixing blocks 301-2. The front and rear sides of the first fixing blocks 301-2 are provided with mutually communicating slots 301-3.

[0035] In summary, during use, the cold water in the cold water tank 304 flows into the interior of the rear housing 302-1 through the first connecting pipe 306, then flows into the first flow pipe 301-5 through the second flow pipe 302-5 and the fitting pipe 302-6. It flows into the front housing 301-1 through the first flow pipe 301-5. Through the heat absorption of the cold water, the cooling effect of the gear reducer body 200 can be accelerated. When the cold water in the front housing 301-1 and the rear housing 302-1 absorbs heat, the water pump 303 is started to suck the water that has absorbed heat in the front housing 301-1 and the rear housing 302-1 into the second connecting pipe 307, and then pumped into the cold water tank 304 by the second connecting pipe 307 for refrigeration by the refrigerator 305. After the pumping is completed, the cold water in the cold water tank 304 is replenished into the front housing 301-1 and the rear housing 302-1 for heat dissipation. When it is necessary to replace the damaged front housing 301-1 or rear housing 302-1, the valve on the first connecting pipe 306 is closed, and then the bolts on the front cover plate 103 and the rear cover plate 102 are removed and the front cover plate 103 and the rear cover plate 102 are opened. After opening, the fixing bolts inside the internal thread hole 301-4 are removed to release the fixation of the insertion rod 302-3. After release, the first connecting pipe 306 and the second connecting pipe 307 are removed, and then the front housing 301-1 or the rear housing 302-1 is removed from the gear reducer body 200 and a new front housing 301-1 or rear housing 302-1 is replaced. The overall operation is simple and can ensure the heat dissipation effect of the front housing 301-1 or the rear housing 302-1.

[0036] It should be noted that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, the electrical connection relationship and the specific circuit structure are not described in detail here.
