Description

Technical Field

[0001] This utility model relates to the field of screening technology, and more specifically, it relates to a gravel screening device for gravel curtain layer repair. Background Technology

[0002] In existing technologies, some screening devices typically have a counterweight plate connected to the end of the rotating shaft to ensure that the equipment can operate in a balanced manner during the screening process. However, the design of these counterweight plates has certain limitations, especially in terms of replacement. Traditional counterweight plates are usually fixedly connected, which means that once the equipment needs to adjust the screening task or change the screen size, the counterweight plate must be manually disassembled and replaced. This process is not only time-consuming and labor-intensive, but may also cause some damage to the equipment, affecting the overall efficiency and stability of the equipment.

[0003] Furthermore, existing counterweight discs are typically designed based on specific screening requirements, lacking flexibility and adaptability. In practical applications, the requirements of screening tasks may vary, such as the type and particle size of the materials to be screened. This necessitates adjustments to counterweight discs of different weights and sizes. However, since existing designs do not provide a quick and convenient replacement mechanism, each replacement of the counterweight disc requires complex disassembly, installation, and adjustment work, which cannot efficiently cope with changes in different screening requirements, thereby reducing the adaptability and production efficiency of the equipment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a gravel screening device for gravel curtain layer repair, so as to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A gravel screening device for gravel curtain layer repair includes a mounting frame with a motor mounted on it. A main shaft is rotatably connected to the upper end face of the mounting frame, and a rotating wheel is sleeved on one end of the main shaft. The output end of the motor is connected to the rotating wheel via a belt. The device also includes a screening mechanism, which includes a counterweight plate with multiple sets of inclined grooves on its inner sidewall. The counterweight plate is sleeved on the other end of the main shaft.

[0009] Preferably, the upper end face of the mounting frame is hinged with a first screen and a second screen, a first discharge plate is connected below the first screen, and a second discharge plate is connected below the second screen. This structure allows the screened sand and gravel to fall into the corresponding discharge plates respectively, realizing efficient grading and diversion of materials.

[0010] Preferably, the main shaft is hinged with a first hinge rod and a second hinge rod, with the other end of the first hinge rod connected to the first screen and the other end of the second hinge rod connected to the second screen. This design can drive the two screens to vibrate synchronously when the main shaft rotates, thereby improving the screening uniformity and efficiency.

[0011] Preferably, a slider is slidably connected in the inclined groove, and three sets of abutment springs are connected to the side wall of each slider. The other end of the abutment spring is connected to an abutment plate, and the side wall of the abutment plate abuts against the side wall of the main shaft. This structure can buffer the vibration of the main shaft through elasticity, maintain the stability of the screening process, and reduce equipment wear.

[0012] Preferably, a sliding rod is provided between each set of abutment springs, the sliding rod is slidably connected to the slider, a connecting spring is connected to the lower end face of the slider, and a locking ball is connected to the other end of the connecting spring. This design enables the slider to move smoothly when subjected to force, and ensures that the locking ball can be locked or released flexibly, thereby improving the convenience of replacing the counterweight plate.

[0013] Preferably, a hexagonal threaded sleeve is rotatably connected inside the counterweight disc, and a fixed cylinder is threaded inside the hexagonal threaded sleeve. This structure facilitates the quick installation or removal of the counterweight disc by rotating the thread, thereby improving operational efficiency.

[0014] Preferably, one end of the fixed cylinder has multiple sets of slots that are adapted to the ball, the ball is embedded in the slot and slidably connected to the slot, and a thrust bearing is provided between the fixed cylinder and the hexagonal threaded sleeve. This design ensures that the counterweight plate is subjected to uniform force during rotation adjustment, rotates smoothly and is reliably positioned.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a gravel screening device for gravel curtain layer repair, which has the following beneficial effects: The screening mechanism of this device can be adjusted according to the particle size variation of the gravel to be screened through the design of the counterweight plate. The staff can easily replace the counterweight plate to achieve the best screening effect for gravel of different particle sizes. This design improves the screening efficiency and avoids the problem of insufficient adaptability caused by the difficulty in replacing the counterweight plate in traditional devices.

[0017] The replacement of the counterweight plate is very convenient. Workers can quickly remove the old counterweight plate and install the new, compatible one simply by rotating the hexagonal threaded sleeve. This design avoids the hassle of disassembling complex parts required in traditional devices, saving time and effort. The cooperation between the hexagonal threaded sleeve and the thrust bearing ensures stable operation, while the cooperation between the ball bearing and the connecting spring effectively prevents jamming during replacement, ensuring smooth operation. Through the fixed connection between the counterweight plate and the main shaft, the screening device can maintain stable operation during work, preventing problems caused by uneven weight distribution or loose parts. This stability not only improves the screening effect but also reduces wear on equipment parts and extends the service life of the equipment, preventing vibrations or imbalances caused by movement. During operation, the motor drives the rotation of the impeller and main shaft. The synchronous rotation of the main shaft and the cooperation of the counterweight plate ensure effective shaking of the screen. The synchronous shaking path of the two screens allows for more uniform screening of sand and gravel. The screened sand and gravel are smoothly discharged through the mesh of the screen. This design improves screening efficiency, ensures effective separation of sand and gravel of different particle sizes, and further optimizes the screening operation. Attached Figure Description

[0028] Please see Figures 1-6 A gravel screening device for gravel curtain layer repair includes a mounting frame 11, a motor 12 mounted on the mounting frame 11, a main shaft 13 rotatably connected to the upper end face of the mounting frame 11, a rotating wheel 14 sleeved at one end of the main shaft 13, and the output end of the motor 12 connected to the rotating wheel 14 via a belt 15. A first screen 16 and a second screen 17 are hinged to the upper end face of the mounting frame 11. A first discharge plate 18 is connected below the first screen 16, and a second discharge plate 19 is connected below the second screen 17. A first hinge rod 110 and a second hinge rod 111 are hinged to the main shaft 13. The other end of the first hinge rod 110 is connected to the first screen 16, and the other end of the second hinge rod 111 is connected to the second screen 17.

[0029] It also includes a screening mechanism, which includes a counterweight plate 21. Multiple sets of inclined grooves 22 are formed on the inner side wall of the counterweight plate 21. The counterweight plate 21 is sleeved on the other end of the main shaft 13. Sliding blocks 23 are slidably connected within the inclined grooves 22. Three sets of abutment springs 24 are connected to the side wall of each set of sliding blocks 23. An abutment plate 25 is connected to the other end of each abutment spring 24. The side wall of the abutment plate 25 abuts against the side wall of the main shaft 13. A sliding rod 26 is provided between each set of abutment springs 24. The sliding rod 26 and the sliding block 23... The sliding connection is provided. A connecting spring 27 is connected to the lower end of the slider 23. A retaining ball 28 is connected to the other end of the connecting spring 27. A hexagonal threaded sleeve 29 is rotatably connected inside the counterweight plate 21. A fixed cylinder 210 is threadedly connected inside the hexagonal threaded sleeve 29. One end of the fixed cylinder 210 has multiple sets of slots 211 that are adapted to the retaining ball 28. The retaining ball 28 is embedded in the slot 211 and slidably connected to the slot 211. A thrust bearing 212 is provided between the fixed cylinder 210 and the hexagonal threaded sleeve 29.

[0030] In this invention, different counterweight discs 21 can be installed according to the particle size of the gravel to be screened in order to achieve better screening results. Before the screening work begins, the operator needs to remove any mismatched counterweight discs 21. Specifically, the operator can rotate the hexagonal threaded sleeve 29 using external tools. The rotation of the hexagonal threaded sleeve 29, under the action of the thrust bearing 212, will drive the fixed cylinder 210 connected to its inner thread to slide along the hexagonal threaded sleeve 29. Because the retaining ball 28 is embedded in the retaining groove 211 opened in the fixed cylinder 210, the fixed cylinder 210 will drive the slider 23 to slide along the inclined groove 22 towards the end with the larger diameter of the inclined groove 22 through the retaining ball 28 and the connecting spring 27. This causes the slider 23 to move synchronously with the abutment plate 25 through the abutment spring 24, thereby releasing the abutment. The tight contact between the connecting plate 25 and the side wall of the main shaft 13 allows the counterweight plate 21 to be removed. The design of the retaining ball 28 and the connecting spring 27 is to facilitate the sliding of the slider 23 and avoid jamming. After removing the old counterweight plate 21, a new and compatible counterweight plate 21 needs to be installed. The operator puts the new counterweight plate 21 back on the end of the main shaft 13, and then rotates the hexagonal threaded sleeve 29 in the opposite direction. The driving fixed cylinder 210 drives the slider 23 to slide along the inclined groove 22 towards the end with the smaller diameter of the inclined groove 22 through the retaining ball 28 and the connecting spring 27. The slider 23 drives the abutment plate 25 to move synchronously through the abutment spring 24, so that the side wall of the abutment plate 25 is tightly abutted against the side wall of the main shaft 13, realizing the fixed connection between the counterweight plate 21 and the main shaft 13. Then the screening work can begin.

[0031] Workers place the gravel to be screened into the first screen 16 and the second screen 17, start the motor 12, and the motor 12 drives the turntable 14 through the belt 15 to drive the main shaft 13 to rotate synchronously. The rotation of the main shaft 13 drives the counterweight plate 21 sleeved at its end to rotate synchronously. At the same time, the main shaft 13 drives the first screen 16 and the second screen 17 to shake through the first hinge rod 110 and the second hinge rod 111. The shaking path of the first screen 16 and the second screen 17 is to move synchronously towards each other and then synchronously in opposite directions. After screening, the gravel falls through the mesh of the first screen 16 or the second screen 17 into the corresponding first discharge plate 18 or the second discharge plate 19 below for discharge and collection.
