[0005] 2. The existing transmission mechanism of the sorting machine needs to be lubricated regularly by humans when in use. This method will increase the workload of the staff and cannot well control the amount of lubricating oil applied, which may easily lead to excessive waste of lubricating oil or too little lubricating oil.

[0043] Among them Figure 1 , 4 As shown in , 5, a lubrication assembly 3 is provided at the top and bottom of the hanging frame 102, and the lubrication assembly 3 includes a U-shaped frame 305 and a hollow shaft 306 installed in a bearing on the inner wall of one side thereof, and the other end of the hollow shaft 306 passes through the bearing on the inner wall of the other side of the U-shaped frame 305, and a sleeve 307 is sleeved on the outer side of the outer wall of the hollow shaft 306, and a sponge 308 is coated on the inner wall of the sleeve 307, and the sleeve 307 can be sleeved on the outer side of the top of the driving sprocket 2011 and the upper transmission sprocket 2062, and a large amount of lubricating oil can be immersed in the sponge 308, and the lubricating oil is coated and squeezed on the driving sprocket 2011 and the upper transmission sprocket 2062 to play a lubricating role;

The inner and outer sides of the hollow shaft 306 are provided with an oil inlet pipe 3061. The other end of the oil inlet pipe 3061 is connected to the delivery pipe 3021 through a pipe joint. The pipe joint plays the role of pipeline connection. The lubricating oil in the hollow shaft 306 can be immersed in the sponge 308 through the oil dripping holes 309.
