Description

Technical Field

[0001] The utility model relates to the technical field of screening machine equipment, in particular to a screen cleaning device for a drum screening machine. Background Art

[0002] As an efficient and multi-functional screening device, the core advantage of a drum screening machine lies in its ability to achieve multi-level fine screening of raw materials or products through its unique drum design, equipped with screens of different pore sizes. In this process, the slow rotation of the drum drives the materials to roll and jump between the screens, thereby realizing the separation of materials with different particle sizes.

[0003] However, when dealing with specific types of materials, such as asphalt milling materials, due to their inherent viscous characteristics, they are prone to form an adhesion layer on the surface of the screen, namely the so-called "screen clogging" phenomenon. Over time, not only will the screening efficiency decrease significantly, because when part of the screen is clogged, the materials cannot pass through normally, thus affecting the smoothness of the overall production line; at the same time, the continuous adhesion on the screen will also increase the wear of the screen, shorten its replacement cycle, thereby indirectly increasing the operating cost and having an adverse impact on the overall service life of the equipment.

[0004] On this basis, it is an urgent need to develop a screen cleaning device for a drum screening machine. Summary of the Utility Model

[0005] The applicant of the present utility model aims at the above-mentioned disadvantages in the existing production technology, and provides a screen cleaning device for a drum screening machine, so as to remove the residues adhered to the screen, and has high cleaning efficiency and low energy consumption.

[0006] The technical solution adopted by the present utility model is as follows: A screen cleaning device for a drum screening machine, including a driving assembly, the driving assembly includes a driving motor, the output end of the driving motor is connected to a speed reducer, and the other end of the speed reducer is connected to a rotating shaft through a coupling; a plurality of cleaning assemblies are evenly distributed on the rotating shaft, each cleaning assembly is wound around the shaft body of the rotating shaft and rotates synchronously along the rotation direction of the rotating shaft; when rotating, the cleaning assembly abuts against the screen and cleans it.

[0007] As a further improvement of the above technical solution:

[0008] Further, the structure of the cleaning assembly is: including a hoop arranged around the rotating shaft, and extension plates are fixedly extended on both sides of the hoop; each extension plate is provided with cleaning sheets, and a pressing plate is arranged on the other side of the cleaning sheets;

[0009] Furthermore, the structure of the cleaning sheet is: including a rubber skin for abutting against the screen, and steel wires are penetrated on the surface of the rubber skin in contact with the screen; when the steel wires contact the screen, the residues adhered to the surface of the screen are removed;

[0010] Furthermore, a bolt assembly is penetrated through the extension plate, the cleaning sheet and the pressing plate, and nuts are arranged at the end positions penetrated by the bolt assembly.

[0011] Furthermore, the hoop disposed around the rotating shaft includes a left hoop and a right hoop. The left hoop and the right hoop are respectively disposed around both sides of the rotating shaft, and are screwed together between the left hoop and the right hoop.

[0012] Furthermore, the extension plate is fixed to the middle positions on both sides of the hoop by welding.

[0013] Further, the other end of the speed reducer is connected to the first coupling, and the other end of the first coupling is connected to the first rotating shaft.

[0014] Furthermore, a second coupling is additionally provided at the tail of the first rotating shaft, and the other end of the second coupling is connected to the second rotating shaft; the second rotating shaft rotates synchronously with the rotation of the first rotating shaft.

[0015] The beneficial effects of the present utility model are as follows:

[0016] The structure of the present utility model is compact and the cleaning is efficient. The driving assembly drives the rotating shaft to rotate through the speed reducer and the coupling. When the rotating shaft rotates, the cleaning assembly abuts against the screen on the drum screen machine, and the adhered residues on the screen are removed by the cleaning sheets of the cleaning assembly, realizing efficient cleaning and only requiring one driving motor to drive. At the same time, a second rotating shaft can be added according to the length of the drum, and the first rotating shaft and the second rotating shaft are connected by a coupling between the first rotating shaft and the second rotating shaft, so that the first rotating shaft and the second rotating shaft rotate synchronously, and the cleaning of a longer drum can be completed.

[0035] Specifically, the hoop 71 arranged around the rotating shaft includes a left hoop and a right hoop. The left hoop and the right hoop are respectively arranged around both sides of the rotating shaft, and the left hoop and the right hoop are screwed together.
