Description

Technical Field

[0001] The utility model belongs to the technical field of roller screens, in particular to a roller screen for filling. Background Art

[0002] The roller screen is composed of multiple screen shafts arranged at intervals to form a screen surface. The incoming material to be screened is transported from one end to the screen surface. The smaller incoming material falls from the gaps between the screen shafts to the bottom of the screen surface, while the larger incoming material is rolled and transported to the other end of the screen surface by the screen shaft, thereby screening different incoming materials. The roller screen is one of the main equipment for preparing mining filler materials. In real life, when the roller screen is in use, since most roller screens are not equipped with auxiliary screening mechanisms, the incoming material to be screened mainly moves on the screen surface through the rotation of the screen shaft and its own gravity. The incoming material with larger volume on the screen surface cannot leave quickly, affecting the screening efficiency. At the same time, large pieces of incoming material of various shapes stay on the screen surface for a long time, which can easily cause the screen shaft to get stuck, thus affecting the safe operation of the equipment.

[0003] A Chinese patent document (application publication number CN209465305U) discloses a roller screen, which includes a box body, a working chamber arranged inside the box body, multiple sets of rotating shafts arranged from left to right inside the box body, multiple sets of motors arranged at the rear end of the box body, and multiple sets of gear discs arranged on the rotating shafts of the multiple motors.

[0004] It can be seen that the patent document cited above also has the same problem. It lacks an auxiliary screening mechanism, so that the incoming material to be screened mainly moves on the screen surface through the rotation of the screen shaft and its own gravity. The incoming material with a larger volume on the screen surface cannot leave quickly, affecting the screening efficiency. At the same time, large pieces of incoming material of various shapes stay on the screen surface for a long time, which can easily cause the screen shaft to get stuck, thereby affecting the safe operation of the equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a filling roller screen to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filling roller screen, comprising a base, two first fixed blocks are installed on one side of the top of the base, a motor is installed on one side of one of the first fixed blocks, a screw is installed on the output end of the motor, a first connecting column is installed on the outer wall of the screw, a roller screen box is installed on one side of the first connecting column, fixing grooves are opened on both sides of the top of the base, and support components are installed on the inner walls of the two fixing grooves.

[0007] As a preferred embodiment, the support assembly includes a support plate, and a pad is installed on one side of the bottom end of the support plate.

[0008] As a preferred embodiment, a second connecting column is installed on one side of the roller screen box, a sliding rod is assembled on one side of the second connecting column, and second fixed blocks are installed at both ends of the sliding rod, and the bottom ends of the two second fixed blocks are respectively fixedly connected to the other side of the top of the base.

[0009] As a preferred embodiment, one end of the screw rod is connected to a side bearing of another first fixed block.

[0010] As a preferred embodiment, a guide groove for auxiliary guiding the movement of the roller screen box is opened at the middle of the two fixed grooves on the top of the base.

[0011] As a preferred embodiment, sliding grooves are provided on both sides of the fixing groove.

[0012] As a preferred embodiment, the outer wall of the sliding rod is provided with a spring for buffering the movement of the roller screen box, one end of the spring is fixedly connected to one side of the second fixed block, and the other end of the spring is fixedly connected to one side of the second connecting column.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are:

[0014] The filling roller screen benefits from the design of the motor, the screw rod and the first connecting column. The forward rotation of the motor drives the screw rod to rotate, and the rotation of the screw rod drives the roller screen box to move to the left through the first connecting column. The reverse rotation of the motor drives the roller screen box to move to the right through the first connecting column. This cycle is repeated, so that the roller screen box moves back and forth. In this way, the roller screen box can be assisted in screening, so that the larger incoming materials on the screen surface can leave quickly without affecting the screening efficiency. At the same time, large incoming materials of various shapes leave the screen surface quickly, avoiding the screen shaft from getting stuck, thereby not affecting the safe operation of the equipment.

[0015] By providing a support assembly, the support assembly is moved outward before the auxiliary screening mechanism is used to drive the roller screen box to move. The support assembly can provide auxiliary support to the roller screen box when it moves, thereby ensuring its smooth movement. BRIEF DESCRIPTION OF THE DRAWINGS
