[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 An automatic lubrication device for a disc screen includes a disc screen equipment body 1. Oil storage tanks 2 are fixed on both sides of the disc screen equipment body 1. The oil inlet 18 of each bearing seat 17 on the same side of the disc screen equipment body 1 is integrated and connected to an oil distributor 4 through an oil distribution pipe 5. A lubrication pump 14 is installed above each of the two oil storage tanks 2. One end of the oil suction pipe 16 connected to the oil suction end of the two lubrication pumps 14 extends to the lower interior of the oil storage tank 2. One end of the oil discharge pipe 15 connected to the oil discharge end of the two lubrication pumps 14 is connected to the oil inlet end of the two oil distributors 4. A controller 8 is installed on one outer wall of the oil storage tank 2. The controller 8 is electrically connected to the two lubrication pumps 14.

[0023] An oil replenishment port 13 is provided on one side of the top of the oil storage tank 2. A filter screen 12 is vertically fixed in the middle of the inner wall of the oil storage tank 2. The oil replenishment port 13 and the oil extraction pipe 16 are located on both sides of the filter screen 12.

[0024] An L-shaped support plate 3 is fixed to one side of the outer wall of the oil storage tank 2. An electric push rod 9 is fixed to the lower end of the horizontal section of the L-shaped support plate 3. The lower end of the electric push rod 9 is connected to the top cover 10.

[0025] A drain valve 6 is installed on the top of the outer wall of the oil storage tank 2, near the oil filling port 13, so that oil and impurities in the oil storage tank 2 can be discharged through the drain valve 6.

[0026] The oil storage tank 2 is fixed on the support leg of the main body 1 of the disc screen equipment, the oil circuit distributor 4 is fixed on the outer wall of the main body 1 of the disc screen equipment, and the oil distribution pipe 5 connected to each bearing seat 17 is fixed to the outer wall of the main body 1 of the disc screen equipment by pipe clamps.

[0027] The lubrication pump 14 can be a pneumatic micro lubrication pump to provide a power source for lubricating oil. By setting the lubrication cycle and oil supply time on the controller 8, the controller 8 controls the start of the lubrication pump 14, so that the lubricating oil in the oil storage tank 2 is extracted. Then, the lubricating oil is delivered to the bearing cavity of each bearing seat 17 through the oil distribution pipe 5 connected by the oil distributor 4, so as to achieve the lubrication effect on the bearing.

[0028] The electric push rod 9 is raised and lowered by the control buttons on the controller 8, so as to drive the top cover 10 to open or close the oil filler port 13.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
