[0041] Specifically, the hydraulic buffer cylinder 204 is filled with cooling buffer oil. The piston plate 205 is hydraulically buffered by the circulation of the cooling buffer oil. At the same time, the cooling buffer oil can be circulated in the heat exchange coil 210 to assist in heat dissipation of the housing 1.

[0042] like Figures 6 to 8 As shown, a piston plate 205 is slidably mounted in the hydraulic buffer cylinder 204. The piston plate 205 supports and limits the piston rod 207. At the same time, the cooling buffer oil in the compression oil storage chamber 208 and the return oil storage chamber 209 can be compressed and guided by controlling the movement of the piston plate 205.

[0043] like Figures 6 to 8 As shown, multiple groups of evenly distributed limit springs 206 are arranged between the hydraulic buffer cylinder 204 and the piston plate 205. The piston plate 205 is supported and limited by the contraction and reset of the multiple groups of limit springs 206.

[0045] like Figures 6 to 8As shown, the piston plate 205 cooperates with the hydraulic buffer cylinder 204 to form a compression oil storage chamber 208 and a return oil storage chamber 209. The cooling buffer oil circulates in the compression oil storage chamber 208 and the return oil storage chamber 209 to play a role of hydraulic buffering limit for the buffer support rod 202.

[0046] like Figures 6 to 8 As shown, a heat exchange coil 210 is arranged on one side of the bottom box 201 close to the housing 1. Liquid cooling is performed on the bottom of the housing 1 by circulating cooling buffer oil in the heat exchange coil 210.

[0047] like Figures 6 to 8 As shown, an oil inlet pipe 211 is connected between the heat exchange coil 210 and the compression oil storage chamber 208. The oil inlet pipe 211 plays a role of connecting and conducting the heat exchange coil 210 and the compression oil storage chamber 208. An oil return pipe 212 is connected between the heat exchange coil 210 and the return oil storage chamber 209. The oil return pipe 212 plays a role of connecting and conducting the heat exchange coil 210 and the return oil storage chamber 209.

[0048] like Figures 4 to 10 As shown, a pair of clamping heat dissipation components are arranged above the assembly base plate 203, and a pair of clamping heat dissipation components are arranged on both sides of the housing 1. The clamping heat dissipation components include a ventilation clamping plate 213, and the ventilation clamping plate 213 is fixedly assembled above the bottom box 201. The housing 1 is auxiliary clamped and limited by the ventilation clamping plate 213.

[0049] The ventilation clamping plate 213 is hollow, so that the air in the ventilation cavity 309 can be easily guided and transported.

[0050] like Figures 4 to 10 As shown, a heat dissipation ventilation pad 214 is fixedly connected to one side of the ventilation clamp 213 close to the housing 1. The heat dissipation ventilation pad 214 plays a role of clamping, buffering and limiting the ventilation clamp 213 and the housing 1. At the same time, the heat dissipation ventilation pad 214 can guide the air to ventilate and dissipate the side wall of the housing 1.

[0051] Specifically, a plurality of evenly distributed ventilation grooves are provided on the side of the heat dissipation and ventilation pad 214 away from the ventilation clamping plate 213. The ventilation grooves are provided to improve the air circulation effect outside the housing 1, thereby ensuring the heat dissipation and cooling effect of the housing 1.

[0052] like Figures 4 to 5 As shown, multiple ventilation grooves are provided with multiple evenly distributed exhaust holes, and the multiple exhaust holes are connected to the ventilation clamping plate 213. The air in the ventilation clamping plate 213 is guided out through the exhaust holes, so as to facilitate ventilation and heat dissipation of the housing 1.

[0053] like Figures 6 to 10As shown, the flow-guiding cooling assembly 3 is fixedly assembled in the housing 1, and the flow-guiding cooling assembly 3 includes a pair of dust-filtering cooling cylinders 301, and the pair of dust-filtering cooling cylinders 301 are fixedly assembled on both sides of the buffer support rod 202. The dust-filtering cooling cylinders 301 filter dust and convey and guide the air delivered by the cooling fan 302.

[0054] like Figures 6 to 10 As shown, a pair of dust filter cooling cylinders 301 are fixedly connected to the opposite sides thereof with a heat dissipation fan 302. By controlling the operation of the heat dissipation fan 302, the outside air is transported into the dust filter cooling cylinder 301 along the heat dissipation fan 302.

[0055] like Figures 6 to 10 As shown, a limited rotation shaft 303 is rotatably assembled in the dust filter cooling cylinder 301. The limited rotation shaft 303 plays the role of assembly limit for the grid 304.

[0056] like Figures 6 to 10 As shown, the outer side of the limiting rotating shaft 303 is fixedly connected with multiple sets of evenly distributed grid frames 304. The flow guide filter screen 305 is assembled and fixed by the multiple sets of grid frames 304.

[0057] like Figures 6 to 10 As shown, the multiple groups of grid frames 304 are all fixedly connected with guide filters 305. The multiple groups of guide filters 305 can be rotated to filter and guide the air in the dust filter cooling cylinder 301.

[0058] like Figures 6 to 10 As shown, an exhaust pipe 306 is fixedly connected above the limit rotating shaft 303. The air in the dust filtering cooling cylinder 301 is led out through the exhaust pipe 306.

[0059] like Figures 6 to 10 As shown, one end of the exhaust pipe 306 outside the bottom box 201 is fixedly connected to a flexible ventilation pipe 307, and one end of the flexible ventilation pipe 307 away from the exhaust pipe 306 is fixedly connected to a guide air pipe 308. The flexible ventilation pipe 307 and the guide air pipe 308 play a role in connecting the exhaust pipe 306 and the ventilation cavity 309, so as to facilitate the air in the dust filter cooling cylinder 301 to be transported to the ventilation cavity 309.

[0060] like Figures 6 to 10 As shown, a ventilation cavity 309 is provided in the bottom box 201, and the ventilation cavity 309 is connected to the guide air duct 308. Air is transported to the ventilation clamping plate 213 and the ventilation bottom hole through the ventilation cavity 309, thereby improving the air circulation speed outside the housing 1.

[0061] Specifically, a plurality of ventilation bottom holes are provided on the top of the bottom box 201, and the plurality of ventilation bottom holes are connected to the ventilation cavity 309. The housing 1 is ventilated and heat is dissipated by exhausting air through the plurality of ventilation bottom holes. The ventilation clamping plate 213 is connected to the ventilation cavity 309. It is convenient to transport air into the ventilation clamping plate 213 through the ventilation cavity 309.

[0062] like Figures 6 to 10 As shown, cooling fins 310 are fixedly mounted on both sides of the bottom box 201, and the cooling fins 310 are arranged corresponding to the dust filter cooling cylinder 301. By controlling the operation of the cooling fins 310 to assist in heat dissipation of the dust filter cooling cylinder 301, the air temperature in the dust filter cooling cylinder 301 is reduced, thereby improving the ventilation and heat dissipation effect of the housing 1.

[0063] In specific use, the housing 1 is assembled and positioned by the cooperation of the assembly bottom plate 203 and a pair of ventilation clamping plates 213. After the assembly is completed, the assembly bottom plate 203 can be supported and limited by the cooperation of the assembly bottom plate 203, the buffer support rod 202, the hydraulic buffer cylinder 204, the piston plate 205 and the piston rod 207. When external vibration occurs, the piston plate 205 can move synchronously with the movement of the buffer support rod 202, the assembly bottom plate 203 and the housing 1 under the action of the piston rod 207, and the volume of the compression oil storage chamber 208 and the return oil storage chamber 209 changes synchronously through the movement of the piston plate 205.

[0064] The piston plate 205 compresses the limit spring 206 so that the cooling buffer oil in the compression oil storage chamber 208 is transported to the heat exchange coil 210 along the oil inlet pipe 211, and the cooling buffer oil in the heat exchange coil 210 can flow back to the return oil storage chamber 209 along the return oil pipe 212. During the reset process of the limit spring 206, the cooling buffer oil in the return oil storage chamber 209 can flow back to the compression oil storage chamber 208 along the heat exchange coil 210 and the oil inlet pipe 211 under the action of the return oil pipe 212, and the buffer support rod 202 is buffered and limited by the circulation of the cooling buffer oil in the compression oil storage chamber 208 and the return oil storage chamber 209. At the same time, the bottom of the housing 1 can be liquid-cooled by the circulation of the cooling buffer oil in the heat exchange coil 210.

[0065] When the temperature of the housing 1 is still high, the operation of the cooling fan 302 can be controlled so that the outside air is transported to the dust filter cooling cylinder 301 along the cooling fan 302. The air in the dust filter cooling cylinder 301 is filtered and guided by multiple groups of guide filters 305 and then transported to the ventilation cavity 309 along the exhaust pipe 306, the flexible ventilation pipe 307, and the guide air pipe 308. The housing 1 is ventilated and cooled by exhausting air through the heat dissipation ventilation pad 214 and the ventilation bottom hole on the assembly bottom plate 203, thereby ensuring the heat dissipation and cooling effect of the housing 1. In addition, the air in the dust filter cooling cylinder 301 can be cooled by controlling the operation of the cooling sheet 310, thereby improving the effect of ventilation and heat dissipation of the housing 1.
