Description

Technical Field

[0001] This utility model relates to the technical field of sand and soil screening instruments, and in particular to an easy-discharge sand and soil screening instrument with a vibration component. Background Technology

[0002] In fields such as construction engineering, geological exploration, and water conservancy and hydropower, particle size distribution analysis of sand is a key step in ensuring project quality. As the core equipment for determining the particle size distribution of sand, the screening efficiency and accuracy of sand screening instruments directly affect the evaluation of material performance and the selection of engineering design parameters. Traditional sand screening instruments mostly adopt static screening or simple mechanical vibration methods. With the widespread application of fine-grained sand and cohesive sand in actual engineering, existing equipment has gradually exposed problems such as low screening efficiency and easy clogging. In addition, with the increasing requirements for the timeliness of material testing in engineering construction, there is an urgent need to develop new screening equipment with efficient anti-clogging and rapid discharge functions to meet the needs of modern engineering testing for precision and efficiency.

[0003] The existing sand and soil screening instruments mainly adopt the following technical solutions: First, a simple manual screening device, which completes screening by manually shaking multiple layers of screens; second, a drum screen, which uses an inclined rotating drum to drive the sand and soil to tumble and pass through the screen; and third, a gravity screen, which completes screening by stacking multiple layers of screens and relying on the gravity of the sand and soil to fall.

[0004] However, existing sand screening instruments generally suffer from problems such as easy screen clogging and low screening efficiency. When processing fine-grained sand or sand containing sticky substances, traditional screening equipment is prone to particle agglomeration due to electrostatic adsorption, mutual embedding, or the influence of humidity. These particles adhere to the screen surface or clog the screen holes, forcing the screening process to be interrupted. In foundation exploration projects with high water content, sticky sand particles are very likely to adhere to the screen to form mud cakes, which not only prolongs the screening time but also causes some particles to fail to pass through the screen. Therefore, a sand screening instrument with a vibration component that facilitates discharge is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-discharge sand and soil screening instrument with a vibration component, which aims to improve the problem in the prior art that sand and soil particles easily adhere to the screen, causing some particles to be unable to pass through the screen and resulting in low screening efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sand and soil screening device with a vibration component includes a base and a screen cylinder. A fixed block is fixedly connected inside the screen cylinder. A rotating rod is rotatably connected to one side of the fixed block. A connecting block is rotatably connected to one side of the rotating rod. A connecting frame is fixedly connected to one side of the connecting block. A rotating plate is fixedly connected to the bottom of the screen cylinder. A motor is fixedly connected to the top of the rotating plate. A turntable is fixedly connected to the output end of the motor. A transmission rod is rotatably connected to one side of the turntable. One side of the transmission rod is rotatably connected to the outer wall of the connecting frame. The transmission rod is slidably connected inside the screen cylinder. A support shaft is fixedly connected to one side of the base. A drive component is provided on the outer wall of the support shaft. A screening component is provided inside the connecting frame.

[0008] The drive assembly includes a telescopic rod, which is rotatably connected to the outer wall of the support shaft. A support block is fixedly connected to the top of the rotating plate, and the output end of the telescopic rod is connected to the support block.

[0009] As a further description of the above technical solution:

[0010] A shaft seat is fixedly connected to the top of the base, and a rotating shaft is rotatably connected inside the shaft seat. One end of the rotating shaft is fixedly connected to the side wall of the rotating plate, and a discharge hopper is provided on the outer wall of the screen cylinder.

[0011] As a further description of the above technical solution:

[0012] The screening assembly includes a screen that is slidably connected inside the connecting frame. A hollow column is fixedly connected to the outer wall of the screen, and a baffle frame is fixedly connected to the top of the screen. A discharge pipe is provided on the outer wall of the baffle frame.

[0013] As a further description of the above technical solution:

[0014] A support plate is fixedly connected to the outer wall of the connecting frame, and a connecting column is fixedly connected to one side of the support plate.

[0015] As a further description of the above technical solution:

[0016] The hollow column has a slot inside, and the hollow column is slidably connected to the outer wall of the connecting column.

[0017] As a further description of the above technical solution:

[0018] The connecting column is equipped with a telescopic column inside, and a limit plate is fixedly connected to one end of the telescopic column.

[0019] As a further description of the above technical solution:

[0020] A locking block is fixedly connected to one side of the limiting plate, and the locking block is slidably connected inside the locking slot.

[0021] As a further description of the above technical solution:

[0022] A spring is fitted on the outer wall of the telescopic column, and the two ends of the spring are fixedly connected to the limiting plate and the inside of the connecting column, respectively.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the turntable is driven to rotate by a motor. The eccentric connection of the turntable causes the transmission rod to push and pull, which in turn drives the connecting frame to reciprocate in the horizontal direction, causing the screen to vibrate. After screening, the rotating plate is driven to rotate by the telescopic rod, which drives the screen cylinder to tilt to achieve material discharge. This effectively avoids the blockage of sand and soil during screening and facilitates material discharge. It solves the problems of low screening efficiency of sand and soil particles and easy residue of sand and soil particles during the discharge process, thereby improving screening efficiency.

[0025] 2. In this utility model, by aligning the hollow column of the outer wall of the screen with and fitting it onto the connecting column of the support plate on the outer wall of the connecting frame, the internal groove of the hollow column squeezes the locking block to cause its compression spring to retract. After it is fully fitted, the spring force pushes the locking block into the groove, thus achieving a firm connection between the screen and the connecting frame. When disassembling, pressing the locking block to disengage it from the groove allows the screen to be pulled out. These structures work together to achieve the effect of quick and convenient installation and disassembly of the screen, solving the problems of complex installation and fixing, cleaning and replacement of screens in traditional screening instruments, thereby improving the maintenance convenience of the screening instrument.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of an easy-discharge sand and soil screening instrument with a vibration component, including a base 1 and a screen cylinder 2. A fixed block 3 is fixedly connected inside the screen cylinder 2. A rotating rod 4 is rotatably connected to one side of the fixed block 3. A connecting block 5 is rotatably connected to one side of the rotating rod 4. A connecting frame 6 is fixedly connected to one side of the connecting block 5. A rotating plate 11 is fixedly connected to the bottom of the screen cylinder 2. A motor 25 is fixedly connected to the top of the rotating plate 11. A turntable 7 is fixedly connected to the output end of the motor 25. A transmission rod 8 is rotatably connected to one side of the turntable 7. The turntable 7 and the transmission rod 8 are eccentrically connected, which can generate regular reciprocating motion. One side of the transmission rod 8 is rotatably connected to the outer wall of the connecting frame 6. The motor 25 transmits power to the screening component through the linkage between the turntable 7 and the transmission rod 8, ensuring the continuity and stability of the screening process. The transmission rod 8 is slidably connected inside the screen cylinder 2. A support shaft 9 is fixedly connected to one side of the base 1. A drive component is provided on the outer wall of the support shaft 9. The screening component is provided inside the connecting frame 6.

[0035] The drive assembly includes a telescopic rod 10, which is rotatably connected to the outer wall of the support shaft 9. A support block 12 is fixedly connected to the top of the rotating plate 11. The telescopic rod 10 controls the precise rotation of the rotating plate 11 and the rotating shaft 14, causing the screen cylinder 2 to tilt. The output end of the telescopic rod 10 is connected to the support block 12. A bearing seat 13 is fixedly connected to the top of the base 1. A rotating shaft 14 is rotatably connected inside the bearing seat 13. One end of the rotating shaft 14 is fixedly connected to the side wall of the rotating plate 11. A discharge hopper 15 is provided on the outer wall of the screen cylinder 2. The design allows the screen cylinder 2 to open smoothly and release the screened sand when tilted to a suitable angle. The screening component includes a screen 16, which is slidably connected inside the connecting frame 6. A hollow column 17 is fixedly connected to the outer wall of the screen 16, and a baffle frame 26 is fixedly connected to the top of the screen 16. The baffle frame 26 can block the unscreened sand and prevent it from falling into the screen cylinder 2 during vibration. A discharge pipe 27 is provided on the outer wall of the baffle frame 26 for discharging the unscreened sand.

[0036] Reference Figures 3-5 A support plate 18 is fixedly connected to the outer wall of the connecting frame 6. A connecting column 19 is fixedly connected to one side of the support plate 18. A slot 20 is opened inside the hollow column 17. The hollow column 17 is slidably connected to the outer wall of the connecting column 19. When the hollow column 17 is fitted onto the outer wall of the connecting column 19, the clever cooperation between the slot 20 and the locking block 23 ensures the firm connection between the screen 16 and the connecting frame 6. A telescopic column 21 is set inside the connecting column 19. A limit plate 22 is fixedly connected to one end of the telescopic column 21. A locking block 23 is fixedly connected to one side of the limit plate 22. The locking block 23 is slidably connected inside the slot 20. A spring 24 is fitted onto the outer wall of the telescopic column 21. The two ends of the spring 24 are fixedly connected to the limit plate 22 and the connecting column 19, respectively. The elastic force of the spring 24 pushes the limit plate 22, so that the locking block 23 slides firmly into the slot 20, completing the installation of the screen 16 and ensuring the stability of the screen 16 during the screening process.

[0037] Working principle: When using this sand screening instrument, the sand is first poured onto the screen 16. Then, the output end of the motor 25 drives the turntable 7 to rotate. The transmission rod 8 on one side of the turntable 7 is eccentrically connected to the turntable 7, which will generate a pushing and pulling action. One end of the transmission rod 8 is rotatably connected to the outer wall of the connecting frame 6 and slidably connected to the inside of the base 1, so that the connecting frame 6 generates reciprocating motion in the horizontal direction. The reciprocating motion of the connecting frame 6 is transmitted to the screen 16, causing the sand on the screen 16 to vibrate. This vibration can effectively prevent the sand from clogging during screening and improve screening efficiency. After screening, the telescopic rod 10 drives the rotating plate 11 and the rotating shaft 14 to rotate, causing the screen cylinder 2 to tilt. The discharge hopper 15 set on the outer wall of the screen cylinder 2 allows the screened sand to be discharged smoothly from the discharge hopper 15 by its own gravity when the screen cylinder 2 is tilted to a suitable angle, realizing convenient discharge. At the same time, the sand remaining above the screen 16 is discharged through the discharge pipe 27, which is convenient for subsequent collection and processing of the screened material.

[0038] When the screen 16 needs to be installed, align the hollow column 17 on the outer wall of the screen 16 with the connecting column 19 on the support plate 18 on the outer wall of the connecting frame 6, so that the hollow column 17 is fitted onto the outer wall of the connecting column 19. During this process, the slot 20 inside the hollow column 17 will squeeze the locking block 23, causing the locking block 23 to compress the spring 24 and retract into the connecting column 19. When the hollow column 17 is fully fitted and the slot 20 and the locking block 23 are aligned, the spring 24 will push the limiting plate 22, causing the locking block 23 to slide into the slot 20, thus achieving a firm connection between the screen 16 and the connecting frame 6, ensuring the stability of the screen 16 during screening. When the screen 16 needs to be disassembled, simply press the locking block 23 to disengage it from the slot 20, and the screen 16 can be easily pulled out, facilitating the cleaning and replacement of the screen 16, improving the convenience of equipment maintenance and screening flexibility, and allowing for quick replacement of the screen 16 according to different sand screening needs.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
