[0003] The existing patent authorization number is: CN221183678U, which discloses a sand filtering device for construction, including a screening net and a main body. The upper part of the screening net is fixedly installed with a fixed frame near the front and rear. The inside of the main body is fixedly installed with a second motor. The output shaft of the second motor is fixedly installed with a gear. The outside of the gear is meshed with another gear. By setting up a screening structure, sand is continuously screened through the screening net. The large particles screened out will remain on the upper surface of the screening net. The two pulleys are driven by a belt to simultaneously drive the reciprocating screw to rotate, thereby driving the two movable blocks to move back and forth, thereby driving the connecting plate to move back and forth on the upper part of the screening net, pushing the large particles screened out into the collection drawers at the front and back of the screening net, thereby speeding up the sand screening speed and improving the screening effect. After analyzing the device, it was found that when filtering sand, the device was unable to perform shaking screening with different intensities according to the amount of sand, resulting in a certain sand filtering capacity, poor adjustability, and limited scope of application.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0016] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0018] See also Figure 1-Figure 5The filter plate 11 is provided with a plurality of springs 15 at its bottom and a plurality of springs 16 at its bottom, and the springs 15 are used to control the filter plate 11 to vibrate and filter. The top of the filter plate 11 is connected to the bottom middle of the filter plate 11, and the tilt angle of the top telescopic member is adjusted by rotating the collar 21 so that when the drive shaft rotates, the four sets of swing springs 15 are cooperated to drive the filter plate 11 to vibrate. The greater the tilt of the telescopic member, the greater the vibration amplitude of the filter plate 11, thereby realizing the adjustment of the filtering vibration degree of the filter plate 11.

[0019] In the embodiment of the present invention, the top of the filter plate 11 is provided with a rectangular structure that is concave downwards, which is used to prevent the sand placed on the filter screen 12 from falling off the filter plate 11 during shaking and filtering. One side of the collection trough 16 is connected to an inclined discharge channel 18 opened on the top of the sand filter base 10, and the filtered sand is discharged through the discharge channel 18.

[0020] There are multiple discharge ports around the top of the filter plate 11. The discharge ports are used to discharge the impurity particles remaining on the filter screen 12. The impurities remaining on the filter plate 11 after the sand is filtered by the filter screen 12 are transferred to the surrounding areas of the downwardly concave rectangular structure on the top of the filter plate 11 during the subsequent continuous shaking process of the filter plate 11, and then discharged outward through the discharge ports. The discharge ports are set as outward inclined slides to ensure that the impurities are quickly discharged.

[0021] Spring positioning cylinders 14 are installed on the top of the sand filter base 10 and the bottom of the filter plate 11 corresponding to both ends of the swing spring 15. The spring positioning cylinders 14 are used to limit the depth of the end of the swing spring 15 to a certain extent, so that it can be compressed and shaken smoothly;

[0022] A set of diverter cones 13 are installed in the middle of the filter screen 12. The sand placed on the filter screen 12 is distributed on the filter screen 12 under the guidance of the diverter cones 13. Since the lower side of the middle of the filter screen 12 is correspondingly provided with structures such as the swing motor 17, when the diverter cone 13 is used to drop the sand along the filter screen 12, the content falling on structures such as the swing motor 17 is reduced.

[0023] In one embodiment of the present invention, the telescopic member includes a screw 25 installed on the top of the swing rod 24, the top of the screw 25 is threadedly connected to a screw barrel 26, the top of the screw barrel 26 is installed with a rotating shaft 27, and the end of the rotating shaft 27 is rotatably connected to a rotating barrel 28 fixed to the bottom of the filter plate 11. By manually rotating the screw barrel 26, the telescopic position of the screw 25 placed inside it is adjusted, thereby adjusting the distance between the swing rod 24 and the bottom of the filter plate 11, thereby adjusting the initial elastic force of the swing spring 15.

[0024] The working principle of the present invention is as follows: in the idle space of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in sequence between the electrical components. The detailed connection means are well known in the art. The following mainly introduces the working principle and process, and does not explain the electrical control. When in use, the sand to be filtered is input along the top of the diverter cone 13, and then evenly spreads to the filter screen 12 around it. At this time, the swing motor 17 is started to drive the drive shaft to rotate, and then the The dynamic adjustment shaft 20 controls the swing of the collar 21 and the telescopic part. Under the connection support of the swing springs 15 around them, the filter plate 11 is driven to shake continuously to quickly filter the sand. When filtering, the amount of sand entering can be adjusted by first stopping the swing motor 17, rotating the locking nut 23, releasing the collar 21, adjusting the swing angle of the collar 21, and then adjusting the inclination of the telescopic part to adjust the initial inclination angle of the filter plate 11. When the swing motor 17 is subsequently driven to shake the filter plate 11, the amplitude of the shaking is increased, thereby increasing the filtration efficiency.

[0025] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
