Description

Technical Field

[0001] This utility model relates to the field of plastic screen cleaning technology, and in particular to a beater for cleaning screens. Background Technology

[0002] Existing plastic wire mesh screens have two shortcomings in actual use. First, because the material being screened is irregularly shaped, it is easy to get stuck in the screen holes, causing material jamming. Moreover, it is difficult for the material to fall out on its own. Over time, this will lead to screen hole blockage, resulting in large-scale material blockage of the screen, reducing the screen penetration rate, and thus reducing screening efficiency and screening effect.

[0003] The usual method involves manually holding the sieve and forcefully slapping it onto a table to clear blockages through vibration. This cleaning process is time-consuming and labor-intensive, and can easily damage the sieve, reducing its lifespan. In addition, the cleaned particles can easily scatter and pollute the working environment. Utility Model Content

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] In the attached diagram, all identical reference numerals refer to the same components.

[0023] like Figure 1-4 As shown, the device includes a housing 1, a beating device 2, and a dust collection device 3. A motor bracket 4 is welded inside the housing 1. A motor 5 is fixedly connected to the motor bracket 4 by bolts. A drive turntable 6 is fixed on the main shaft of the motor 5. A transmission pin 7 is movably connected to the drive turntable 6. A connecting rod 8 is rotatably mounted on one side of the drive turntable 6. The drive turntable 6 and the connecting rod 8 are connected by the transmission pin 7. The beating device 2 includes a connecting shaft 9, a rocker arm 10, a fixed seat 11, and a beating plate 12. The connecting rod 8 is connected to the middle of the rocker arm 10 by a hinge through the connecting shaft 9. The side of the fixed seat 11 is fixedly connected to the inside of the housing 1. One end of the rocker arm 10 is rotatably connected to the fixed seat 11. The beating plate 12 is fixed to the end of the rocker arm 10. The dust collection device 3 is located below the housing 1.

[0024] In this embodiment, the motor 5 drives the rocker arm 10 to swing up and down periodically, thereby driving the striking plate 12 to move up and down periodically, which in turn strikes the vibrating screen, causing dirt and other contaminants on the screen to vibrate off and clean the screen.

[0025] The method of using this utility model is as follows:

[0026] 1. Place the screen to be cleaned on the table 13 and move it directly below the beater 12 so that the beater 12 can hit the screen when it falls.

[0027] 2. Start motor 5. Driven by motor 5, the beater 12 begins to move up and down periodically, periodically hitting and vibrating the screen to remove the clogging impurities or particles from the screen.

[0028] 3. The particles or impurities that are knocked out fall into the dust collection funnel below under the action of gravity. When a certain amount is accumulated, the collected particles or impurities are collected and recycled.

[0029] Furthermore, the drive turntable 6 is circular, and a sleeve connected to the motor 5 is provided at the center of the drive turntable 6. The center of the drive turntable 6 is coaxial with the rotating shaft of the motor 5. The drive turntable 6 and the rotating shaft of the motor 5 are fixed by a key connection. A through hole connected to the transmission pin 7 is provided on the end face of the drive turntable 6.

[0030] Furthermore, the dust collection device 3 includes a table 13 disposed on one side of the outer casing 1 and a dust collection funnel 14 fixed to the lower part of the outer casing 1. The table 13 is provided with evenly distributed mesh holes and is used to place the screen to be cleaned. The bottom of the dust collection funnel 14 is provided with a retractable baffle for releasing dust.

[0031] In this embodiment, four support rods are provided at the four corners of the dust collection funnel 14, and the table 13 has evenly distributed mesh holes. The table 13 is used to place the screen to be cleaned, and the bottom of the dust collection funnel 14 is provided with a retractable baffle for releasing dust. When a certain amount of screen blockage material accumulates in the dust collection funnel 14, the retractable baffle can be opened to discharge the blockage material. A dust collection device (not shown) is also provided on one side of the table 13. The dust collection device's suction port faces the beating plate 12 and is used to absorb the dust generated during the beating and cleaning of the screen in real time.

[0032] Furthermore, the connecting rod 8 is elongated, with a through hole at one end. The connecting rod 8 is rotatably connected to the drive turntable 6 through the through hole to drive the connecting rod 8 to swing. The other end of the connecting rod 8 also has a through hole, and the rocker arm 10 has a connecting hole in the middle. The connecting rod 8 and the middle of the rocker arm 10 are hinged through the through hole to drive the rocker arm 10 to swing around the end of the connecting rod 8.

[0033] Furthermore, the fixing seat 11 is fixed to the inner wall of the outer shell 1 by bolts. Preferably, the fixing seat 11 is L-shaped, and the side of the fixing seat 11 is fixed to the inner wall of the outer shell 1 by bolts. A hinge bracket is provided on the bottom surface of the fixing seat 11, and a round hole is provided at the upper end of the rocker arm 10. The rocker arm 10 is hinged to the fixing seat 11 through the round hole, and the rocker arm 10 can swing up and down periodically around the center of the hinge hole on the fixing seat 11.

[0034] Furthermore, the striking plate 12 is shaped like a palm and is made of rubber. The striking plate 12 can be bent up and down. The bottom of the rocker arm 10 is flat and has several connecting holes. The striking plate 12 and the rocker arm 10 are fixedly connected through the connecting holes. When the rocker arm 10 swings up and down, the striking plate 12 bends and swings up and down periodically to strike the screen, vibrating and cleaning the blockage on the screen.

[0035] In this embodiment, the striking plate 12 is detachably connected to the rocker arm 10 by bolts. After a certain period of use, it is convenient to replace the striking plate 12. The material hardness of the striking plate 12 is lower than that of the screen to avoid damaging the screen during striking and impact.

[0036] This invention relates to a beater for cleaning screens. Through the reciprocating swing of the rocker arm, it achieves periodic striking vibration of the screen, thereby achieving the purpose of automatic cleaning of the screen and solving the problems of time-consuming and laborious manual cleaning of screens, as well as damage to the screen.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
