Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a sand screening device for building construction. Background Technology

[0002] Sand screening devices are indispensable in construction processes, primarily used to sieve sand to meet the particle size requirements of different construction stages. However, in existing sand screening devices used in construction, the screen mesh, being a vulnerable component, frequently requires replacement and maintenance. Traditional sand screening devices suffer from complex screen mesh installation structures and cumbersome disassembly processes, increasing worker workload and reducing equipment efficiency. Therefore, designing a sand screening device for construction that facilitates screen mesh disassembly is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a sand screening device for construction that facilitates the disassembly of the screen, so as to solve the problem of difficult screen disassembly of traditional sand screening devices mentioned in the background art.

[0004] A sand screening device for construction includes a support, a dual-shaft motor at one end of the support, and screen frames movably mounted on the four corners of the support via support plates. A crank is fixed on the output shaft of the dual-shaft motor, and the crank is movably connected to the other end of the screen frame via a connecting rod. A guide groove is provided on the screen frame, and a screen mesh is slidably connected inside the guide groove. A disassembly mechanism is provided between the screen frame and the screen mesh.

[0005] The easy-to-disassemble mechanism includes a limiting mechanism mounted on the screen frame and limiting holes formed on the screen mesh. The limiting mechanism includes a sliding cavity formed on the screen frame, a sliding plate disposed inside the sliding cavity, a limiting head fixed to one end of the sliding plate, a pull rod fixed to the other end of the sliding plate, and a spring sleeved on the pull rod inside the sliding cavity.

[0006] Preferred technical solution

[0007] The bottom of the support is equipped with a shock-absorbing pad made of rubber, which can effectively reduce the vibration generated during the operation of the device, avoid damage to the support and other components, and reduce noise pollution.

[0008] The dual-axis motor is fixed to the support by a motor mount. A buffer component, which can be a spring or a rubber block, is provided between the motor mount and the support to further enhance the shock absorption effect of the motor and ensure the stable operation of the dual-axis motor.

[0009] The support plate and the screen frame are movably connected by a rotating shaft, and the rotating shaft is equipped with a bearing, which makes the screen frame move more smoothly during the movement, reduces friction loss, and improves the service life of the device.

[0010] The two ends of the connecting rod are movably connected to the crank and the screen frame respectively by pins. The pins are provided with wear-resistant sleeves to prevent wear between the pins and the connecting rod, crank and screen frame, and improve the reliability of the connection.

[0011] The guide groove has a T-shaped or dovetail-shaped cross section, and the screen is provided with sliders on both sides that match the guide groove, so that the screen slides more stably in the guide groove and avoids the screen from shifting or falling off during the screening process.

[0012] The end of the limiting head is hemispherical or conical, and the shape of the limiting hole matches the shape of the end of the limiting head, which facilitates the insertion of the limiting head into the limiting hole and improves the connection efficiency and stability of the easy-to-disassemble mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the screen needs to be disassembled, pull the lever to disengage the limiting head from the limiting hole, then slide the screen along the guide groove to remove it from the screen frame. To install the screen, insert it into the screen frame along the guide groove, release the lever, and the limiting head will insert into the limiting hole under the action of the spring, completing the installation. This invention, through its easy-to-disassemble mechanism, enables rapid disassembly and installation of the screen, improving equipment maintenance efficiency and reducing worker workload.

[0025] A sand screening device for building construction.

[0026] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "In the construction process, sand screening devices are indispensable equipment, mainly used to screen sand to meet the particle size requirements of different construction stages. However, in the use of existing sand screening devices for construction, the screen mesh, as a vulnerable component, frequently needs to be replaced and repaired. The traditional sand screening device has a complex screen mesh installation structure and a cumbersome disassembly process, which not only increases the labor intensity of workers but also reduces the working efficiency of the equipment." Considering practical use, this problem is clearly a real and difficult-to-solve issue. Therefore, to solve this technical problem, a sand screening device for construction is provided.

[0028] Based on the above, a sand screening device for construction includes a support 1, a dual-shaft motor 2 is installed at one end of the support 1, and a screen frame 4 is movably installed at the four corners of the support 1 via support plates 3. A crank 5 is fixed on the output shaft of the dual-shaft motor 2, and the crank 5 is movably connected to the other end of the screen frame 4 via a connecting rod 6. A guide groove 7 is provided on the screen frame 4, and a screen 8 is slidably connected inside the guide groove 7. A disassembly mechanism 9 is provided between the screen frame 4 and the screen 8.

[0029] The easy-to-disassemble mechanism 9 includes a limiting mechanism 91 disposed on the screen frame 4 and a limiting hole 92 opened on the screen 8. The limiting mechanism 91 includes a sliding cavity 911 opened on the screen frame 4, a sliding plate 912 disposed inside the sliding cavity 911, a limiting head 913 fixed to one end of the sliding plate 912, a pull rod 914 fixed to the other end of the sliding plate 912, and a spring 915 sleeved on the pull rod 914 inside the sliding cavity 911.

[0030] The bottom of the support 1 is equipped with a shock-absorbing pad made of rubber, which effectively reduces vibrations generated during device operation, preventing damage to the support 1 and other components, and reducing noise pollution. The dual-shaft motor 2 is fixed to the support 1 via a motor mount. A buffer, which can be a spring or rubber block, is placed between the motor mount and the support 1 to further enhance the motor's shock absorption effect and ensure stable operation of the dual-shaft motor 2. The support plate 3 and the screen frame 4 are movably connected via a rotating shaft with bearings, allowing the screen frame 4 to move more smoothly, reducing friction loss and extending the device's service life. The two ends of the connecting rod 6 are movably connected to the crank 5 and the screen frame 4 respectively via pins. Wear-resistant sleeves are provided on the pins to prevent wear between the pins and the connecting rod 6, crank 5, and screen frame 4, improving connection reliability. The guide groove 7 has a T-shaped or dovetail-shaped cross-section. Sliding blocks matching the guide groove 7 are provided on both sides of the screen 8, making the screen 8 slide more stably within the guide groove 7 and preventing the screen 8 from shifting or falling off during screening. The end of the limiting head 913 is hemispherical or conical, and the shape of the limiting hole 92 matches the shape of the end of the limiting head 913, which facilitates the insertion of the limiting head 913 into the limiting hole 92 and improves the connection efficiency and stability of the easy-to-disassemble mechanism 9.

[0031] During operation, the dual-shaft motor 2 drives the crank 5 to rotate.

When the screen 8 needs to be replaced or repaired, pull the lever 914 to disengage the limiting head 913 from the limiting hole 92, and then slide the screen 8 along the guide groove 7 to remove it from the screen frame 4. During installation, insert the screen 8 into the screen frame 4 along the guide groove 7, release the lever 914, and under the action of the spring 915, the limiting head 913 inserts into the limiting hole 92, completing the installation of the screen 8.
