[0026] Please see Figures 1 to 4 The embodiments of this application include: This application discloses a grinding mill auxiliary power generation device, including:

[0027] The system comprises an engine 110, a first pulley 120, a generator 210, a second pulley 211, and a transmission belt 240. The engine 110 is fixedly mounted on the grinding machine 100 and can be a propane engine. The first pulley 120 is mounted on the output shaft of the engine 110, and the output shaft drives the first pulley 120 to rotate; that is, the first pulley 120 rotates as the engine 110 operates. The generator 210 is mounted on the grinding machine 100 via a connecting bracket and can be a 24V DC generator. The second pulley 211 is mounted on the input shaft of the generator 210 and drives the input shaft to rotate. The transmission belt 240 is fitted onto the first pulley 120 and the second pulley 211. The first pulley 120 drives the transmission belt 240 to rotate through friction, and the transmission belt 240 drives the second pulley 211 to rotate through friction.

[0028] This application utilizes an engine 110 that consumes fuel such as propane for rotation. The first pulley 120 on the engine 110 rotates as the engine 110 operates. The first pulley 120 drives the second pulley 211 to rotate via a transmission belt 240. The second pulley 211 drives the generator 210 to rotate, thereby achieving the effect of power generation. The generator 210 can charge the storage battery, and the storage battery can continuously supply power to the drive motor 20, thereby driving the grinder 100 to move. This solves the problem of insufficient 12V voltage in the existing engine 110.

[0029] In a preferred embodiment of this application, the connecting frame includes a first connecting frame 220 and a second connecting frame 260. The generator 210 and the first connecting frame 220 are movably and fixedly connected. The generator 210 can move within the first connecting frame 220 and be fixed in a suitable position. The generator 210 and the second connecting frame 260 are rotatably connected. Specifically, the generator 210 is equipped with an upper connecting sleeve 213 and a lower connecting sleeve 214. The generator 210 is limited by the upper connecting sleeve 213 and the lower connecting sleeve 214. Preferably, the upper connecting sleeve 213 and the lower connecting sleeve 214 are connected by connecting rods 218, such as bolts, and the number of connecting rods 218 can be three or four. The upper connecting sleeve 213 and the lower connecting sleeve 214 are provided with connecting holes corresponding to the connecting rods 218.

[0030] In a preferred embodiment of this application, there is a certain distance between the upper connecting sleeve 213 and the lower connecting sleeve 214. A portion of the second connecting frame 260 is disposed between the upper connecting sleeve 213 and the lower connecting sleeve 214, and is rotatably connected to the upper connecting sleeve 213 and the lower connecting sleeve 214 via a connecting shaft 217. That is, the generator 210 can rotate on the second connecting frame 260, and the other portion of the second connecting frame 260 is fixedly mounted on the grinding machine 100. The first connecting frame 220 of this application includes a first connecting portion 221, a second connecting portion 222, and a third connecting portion 223 integrally formed and connected in sequence. One end of the first connecting portion 221 is integrally formed and connected to one end of the second connecting portion 222 (the lower end in the figure), and the other end of the second connecting portion 222 (the upper end in the figure) is integrally formed and connected to one end of the third connecting portion 223. The first connecting frame 220 of this application is fixedly installed on the grinding machine 100 through the first connecting part 221. Specifically, the first connecting part 221 of this application is provided with a connecting hole. The first connecting part 221 can be fixedly connected to the grinding machine 100 by screws or bolts inserted into the connecting hole. The third connecting part 223 of this application is provided with an elongated hole 224, which runs through the third connecting part 223 from top to bottom. The generator 210 of this application is connected to the third connecting part 223 through the connecting seat 230 and the first bolt 215 inserted into the elongated hole 224. When the first bolt 215 and the connecting seat 230 are locked in the elongated hole 224, the generator 210 of this application is fixed on the third connecting part 223. When the first bolt 215 and the connecting seat 230 are not tight, the first bolt 215 and the connecting seat 230 can slide in the elongated hole 224. The first connecting frame 220 of this application also includes a fourth connecting part 226, which is integrally formed and connected to the other end of the third connecting part 223.

A nut 233 is also threadedly connected to the second bolt 232, and the nut 233 is disposed between the fourth connecting part 226 and the connecting block 231. The position of the generator 210 in this application can be moved appropriately because, on the one hand, the generator 210 can rotate on the second connecting frame 260 through the connecting shaft 217, and on the other hand, since the position of the connecting block 231 can be adjusted in the elongated hole 224, the position of the generator 210 can also be adjusted appropriately, thereby adjusting the position between the first pulley 120 and the second pulley 211, and thus adjusting the tension of the transmission belt 240.

[0032] In a preferred embodiment of this application, the generator 210 is electrically connected to the storage battery, and the storage battery is electrically connected to the drive motor 130. For safety, the power generation auxiliary device 200 of this application may also be provided with a protective cover 250 above the first pulley 120 and the second pulley 211, and the protective cover 250 may be fixed on the grinding machine 100.
