Abstract
Description
Technical Field
[0001] This utility model relates to the field of sand screening devices, and in particular to an engineering sand screening device. Background Technology
[0002] In construction, water conservancy, and other engineering projects, natural sand and gravel often contain soil, impurities, and particles of varying sizes, making it unsuitable for meeting high-standard material requirements. Manual sand screening is inefficient and lacks precision, thus necessitating the development and application of highly efficient and automated engineering sand screening devices. These devices are widely used in fields such as construction engineering.
[0003] The structure of the engineering sand screening device includes a screening mechanism to achieve particle classification, as well as a frame and protective devices for fixing components and ensuring safety. Its main function is to separate impurities in sand and gravel to improve cleanliness, classify by particle size to meet different engineering material standards, and replace manual labor to greatly improve processing efficiency, thereby ensuring project progress and reducing labor costs.
[0004] The shortcomings of existing technologies are mainly reflected in two aspects: First, the screening stability is poor, relying mainly on simple frame support without a special reinforcement structure. The frame is prone to deformation during vibration operation, and there is a lack of precise ground anchor fixing design, making the device prone to displacement and affecting the screening accuracy. Second, the operation depends on manual labor, and the fixing process requires manual adjustment of the ground anchor, which is labor-intensive and has low fixing accuracy, making it difficult to adapt to the high-efficiency operation requirements of various engineering scenarios. Therefore, an engineering sand screening device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an engineering sand screening device, which aims to improve the problem of instability during operation in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an engineering sand screening device, including support legs, a connecting rod installed between the support legs, a screen fixedly connected to the top of the connecting rod, and a fixing mechanism installed on the inner side of the support legs;
[0007] The fixing mechanism includes a ground anchor and a drive motor. The ground anchor has a threaded rod connected to its inner side, and a second gear is fixedly connected to the top of the threaded rod.
[0008] As a further description of the above technical solution:
[0009] Two vibration motors are fixedly connected to one side of the connecting rod;
[0010] As a further description of the above technical solution:
[0011] The output end of the drive motor is fixedly connected to a first gear, and the top end of the threaded rod is fixedly connected to a second gear, which meshes with the first gear and the second gear.
[0012] As a further description of the above technical solution:
[0013] A reinforcing rod is fixedly connected between the supporting legs;
[0014] As a further description of the above technical solution:
[0015] The ground anchor is slidably connected to the inside of the support leg;
[0016] As a further description of the above technical solution:
[0017] The drive motor is fixedly connected to one side of the support leg.
[0018] This utility model has the following beneficial effects:
[0019] 1. In this utility model, the fixing mechanism uses a drive motor to drive gear transmission, which drives the threaded rod to rotate. In conjunction with the sliding guide of the ground anchor and the support leg, the ground anchor is accurately driven into the soil and fixed, which can effectively prevent the device from vibrating and displacing. No manual fixing is required, which reduces labor costs and improves the overall stability of the device during operation, making it suitable for various engineering scenarios.
[0020] 2. In this utility model, the screen is driven to vibrate by a vibrating motor, which causes the sand and gravel to tumble and move on the screen to achieve particle size separation. At the same time, the frame composed of the supporting legs and connecting rods is reinforced by reinforcing rods to enhance the stability of the frame and ensure the structural stability during the screening process. This not only improves the efficiency and accuracy of sand and gravel separation, but also avoids the frame from deforming due to vibration, ensuring long-term operational reliability.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0028] Reference Figures 1-4 An embodiment of this utility model is provided: an engineering sand screening device, including support legs 1, connecting rods 2 installed between the support legs 1, a screen 5 fixedly connected to the top of the connecting rods 2, and a fixing mechanism 6 installed on the inner side of the support legs 1;
[0029] The support leg 1 serves as the basic load-bearing component of the device. It forms a stable frame structure with the connecting rod 2, providing an installation platform for the screen 5 and bearing the overall weight. The fixing mechanism 6 is used to stabilize the device on the working ground, preventing displacement or shaking caused by vibration during the screening process and ensuring the stability of the overall operation.
[0030] The fixing mechanism 6 includes a ground anchor 11 and a drive motor 7. A threaded rod 10 is threadedly connected to the inner side of the ground anchor 11, and a second gear 9 is fixedly connected to the top of the threaded rod 10.
[0031] The ground anchor 11 can penetrate deep into the ground. The anti-overturning ability of the device is enhanced by the engagement with the ground. The drive motor 7 provides power for the operation of the fixing mechanism 6. The threaded connection design between the threaded rod 10 and the ground anchor 11 allows the rotation of the threaded rod 10 to be converted into the vertical linear motion of the ground anchor 11, thereby realizing the insertion or extraction of the ground anchor 11. The second gear 9 serves as an intermediate component for power transmission, receiving power from the drive source and driving the threaded rod 10 to operate.
[0032] Reference Figure 1 Two vibration motors 3 are fixedly connected to one side of the connecting rod 2.
[0033] When the vibrating motor 3 is working, it generates high-frequency vibration, which is transmitted to the screen 5 through the connecting rod 2. This causes the sand and gravel on the screen 5 to vibrate. The inertial force generated by the vibration makes the material roll and move continuously on the surface of the screen 5. Smaller particles of sand and gravel can fall through the mesh of the screen 5, while larger particles of impurities or sand and gravel are left on the surface of the screen 5 and gradually move towards the discharge end, thereby achieving the effect of screening and separation. The setting of two vibrating motors 3 can enhance the vibration intensity and uniformity, and improve the screening efficiency.
[0034] Reference Figures 3-4 The output end of the drive motor 7 is fixedly connected to the first gear 8, and the top end of the threaded rod 10 is fixedly connected to the second gear 9. The first gear 8 and the second gear 9 mesh with each other.
[0035] When the drive motor 7 starts, its output drives the first gear 8 to rotate. Since the first gear 8 and the second gear 9 mesh with each other, the rotational force of the first gear 8 is transmitted to the second gear 9, which in turn drives the threaded rod 10 to rotate synchronously. Through the transmission method of gear meshing, the power of the drive motor 7 can be stably transmitted to the threaded rod 10, ensuring the stability of the rotation of the threaded rod 10 and the efficiency of power transmission, and providing reliable power for the lifting and lowering of the ground anchor 11.
[0036] Reference Figure 1 A reinforcing rod 4 is fixedly connected between the support legs 1.
[0037] The reinforcing rod 4 is connected between the support legs 1 to form a stable structure with multi-directional force, which can disperse the pressure and vibration impact force borne by the support legs 1, and prevent the support legs 1 from deforming or breaking due to excessive force during long-term operation, thereby further enhancing the structural strength and stability of the overall frame of the device.
[0038] Reference Figures 3-4 The ground anchor 11 is slidably connected to the inside of the support leg 1.
[0039] This sliding connection provides guidance for the up-and-down movement of the ground anchor 11, ensuring that the ground anchor 11 can rise and fall vertically along the preset trajectory inside the support leg 1 under the drive of the threaded rod 10, avoiding the ground anchor 11 from deviating or getting stuck during the movement, and ensuring that the ground anchor 11 can accurately and smoothly complete the actions of being fixed in the soil or pulled out and retracted.
[0040] Reference Figures 3-4 The drive motor 7 is fixedly connected to one side of the support leg 1.
[0041] Fixing the drive motor 7 to the support leg 1 ensures that the motor and other components of the fixing mechanism 6 maintain a stable relative position, ensuring the accuracy of gear meshing during power transmission, while reducing vibration displacement during motor operation, thus guaranteeing the stability and service life of the drive motor 7.
[0042] Working principle: When the sand screening device of this project is working, the support leg 1, connecting rod 2, and reinforcing rod 4 together form a stable frame, supporting the overall structure and providing a foundation for the installation of each component. After starting, the vibrating motor 3 generates high-frequency vibration and transmits it to the screen 5 through the connecting rod 2, causing the sand and gravel on the screen 5 to tumble and move under the action of vibration, realizing the separation of materials of different particle sizes. At the same time, the fixing mechanism 6 starts to work. After the drive motor 7 starts, it drives the first gear 8 to rotate. Because the first gear 8 meshes with the second gear 9, the power is transmitted to the threaded rod 10 to make it rotate synchronously. The threaded connection between the threaded rod 10 and the ground anchor 11, together with the sliding guide of the ground anchor 11 on the inside of the support leg 1, causes the ground anchor 11 to descend vertically along the inside of the support leg 1 and penetrate into the ground. The engagement between the ground anchor 11 and the ground realizes the stable fixation of the device, avoiding displacement or shaking of the device during vibration operation, and ensuring the stable and efficient screening process.
[0043] 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.
