Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, and more specifically, to a standard inspection sieve for construction engineering quality testing. Background Technology

[0002] With the rapid development of the construction industry, the government is also continuously strengthening its supervision of the industry. Standardization in the construction industry will be further promoted, and requirements for project quality and safety management will become more stringent. Companies within the industry need to attach great importance to regulatory compliance, strengthen internal management, improve project quality, and ensure the safety and stability of projects.

[0003] In construction projects, standard inspection sieves are typically used to test the quality of the work. When a standard inspection sieve is in use, the operator first activates a device. When activated, a motor drives a cam to rotate. As the cam rotates, it contacts the sieve screen, causing the screen to move upwards. When the cam is not in contact with the screen, a spring at the bottom of the screen moves it downwards. This up-and-down movement of the screen filters the material above it. However, prolonged impact from the protrusions on the screen causes wear at the impact points, increasing operating costs. Therefore, modification and optimization are necessary. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a standard inspection sieve for construction engineering quality testing, which has the advantages of low cost and high efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a standard inspection sieve for construction engineering quality testing, comprising legs and a shell, wherein the shell is fixedly disposed above the legs;

[0006] A motor frame is fixedly installed on one side of the outer casing, a motor is fixedly installed on one side of the motor frame, a gear is fixedly installed above the drive shaft of the motor, a fixing sleeve is fixedly installed on one side of the outer casing, an arc-shaped rack is movably installed on the side of the fixing sleeve, the arc-shaped rack meshes with the gear, a connecting plate is fixedly installed on one side of the arc-shaped rack, a connecting block is fixedly installed on one side of the connecting plate, a groove is formed on one side of the outer casing, one side of the connecting block passes through the groove and extends into the interior of the outer casing, and a screen is fixedly installed on one side of the connecting block.

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a standard inspection sieve for construction engineering quality testing, including a support leg 1 and a shell 2, with the shell 2 fixedly disposed above the support leg 1;

[0023] A motor frame 5 is fixedly installed on one side of the outer casing 2. A motor 6 is fixedly installed on one side of the motor frame 5. A gear 7 is fixedly installed above the drive shaft of the motor 6. A fixing sleeve 8 is fixedly installed on one side of the outer casing 2. An arc-shaped rack 9 is movably installed on the side of the fixing sleeve 8. The arc-shaped rack 9 meshes with the gear 7. A connecting plate 10 is fixedly installed on one side of the arc-shaped rack 9. A connecting block 11 is fixedly installed on one side of the connecting plate 10. A groove 21 is opened on one side of the outer casing 2. One side of the connecting block 11 passes through the groove 21 and extends into the interior of the outer casing 2. A screen 12 is fixedly installed on one side of the connecting block 11.

[0024] When the operator uses the device, they first start the motor 6. When the motor 6 starts, it drives the gear 7 to rotate. As the gear 7 rotates, it meshes with the arc-shaped rack 9, causing the arc-shaped rack 9 to move back and forth. When the arc-shaped rack 9 moves back and forth, it drives the connecting plate 10 to move back and forth. When the connecting plate 10 moves back and forth, it drives the connecting block 11 to move back and forth. When the connecting block 11 moves back and forth, it drives the screen 12 to move back and forth. At this time, the material can be poured from the top of the feed hopper 4 onto the top of the screen 12.

[0025] By starting the motor 6, the gear 7 is driven to rotate. When the gear 7 rotates, it meshes with the arc-shaped rack 9, causing the arc-shaped rack 9, connecting plate 10, connecting block 11, and screen 12 to move back and forth simultaneously. The material is then poured from the feed hopper 4 onto the screen 12, thus achieving material screening. Compared with traditional devices, this device avoids the wear caused by the impact of the protrusions by moving the screen 12 back and forth, thereby reducing the wear of the device, increasing the service life of the screen 12, and reducing the operating cost of the device.

[0026] A handle 16 is rotatably mounted on one side of the outer casing 2. One end of the handle 16 extends into the interior of the outer casing 2 and is fixedly mounted with a threaded rod 17. A threaded block 18 is threaded onto the outer surface of the threaded rod 17. A connecting rod 19 is hinged above the threaded block 18. A feed plate 20 is hinged to one end of the connecting rod 19. One end of the feed plate 20 is hinged to the inner side of the outer casing 2.

[0027] When the operator uses the device, they first turn the handle 16. When the handle 16 turns, it drives the threaded rod 17 to rotate. When the threaded rod 17 rotates, because the threaded block 18 and the threaded rod 17 are connected by threads, the threaded block 18 will move as the threaded rod 17 rotates. When the threaded block 18 moves, it will drive one end of the connecting rod 19 to move, thereby adjusting the height of the other end of the connecting rod 19, which in turn drives the feed plate 20 to adjust its angle.

[0028] By rotating the handle 16, the threaded rod 17 is driven to rotate. Since the threaded block 18 and the threaded rod 17 are connected by a thread, the rotation of the threaded rod 17 causes the threaded block 18 to move, thereby adjusting the movement of one end of the connecting rod 19 and the height of the other end, as well as the angle of the discharge plate 20. Compared with traditional devices, this device can change the height at which qualified materials fall by adjusting the angle of the discharge plate 20, thus facilitating the collection of qualified materials by the staff and improving the working efficiency of the device.

[0029] Among them, a guide shell 3 is fixedly installed on one side of the outer shell 2, and the guide shell 3 is located below the screen 12.

[0030] The guide shell 3 is designed to guide non-conforming materials coming out of the device, thereby improving the device's working efficiency.

[0031] The upper part of the outer shell 2 is fixedly installed with a feed hopper 4, and the bottom of the feed hopper 4 extends into the interior of the outer shell 2.

[0032] The design of the feed hopper 4 makes it easy for workers to add materials into the device through the feed hopper 4.

[0033] Among them, a second motor 13 is fixedly installed on one side of the outer shell 2, and the drive shaft of the second motor 13 extends into the interior of the outer shell 2 and a stirring blade 14 is fixedly installed thereon.

[0034] The design of motor 213 allows for the large-scale dispersion of materials entering the outer casing 2, thus facilitating the detection and screening of materials.

[0035] Among them, a protective shell 15 is fixedly installed on one side of the outer shell 2, and the protective shell 15 is located on the outside of the motor 2 13.

[0036] The protective shell 15 is designed to protect the outside of motor 2 13, preventing dirt from entering the interior of motor 2 13 and affecting its operation.

[0037] Working principle and usage process of this utility model:

[0038] When the operator uses the device, they first start the motor 6. When the motor 6 starts, it drives the gear 7 to rotate. As the gear 7 rotates, it meshes with the arc-shaped rack 9, causing the arc-shaped rack 9 to move back and forth. When the arc-shaped rack 9 moves back and forth, it drives the connecting plate 10 to move back and forth. When the connecting plate 10 moves back and forth, it drives the connecting block 11 to move back and forth. When the connecting block 11 moves back and forth, it drives the screen 12 to move back and forth. At this time, the material can be poured from the top of the feed hopper 4 onto the top of the screen 12.

[0039] When the operator uses the device, they first turn the handle 16. When the handle 16 turns, it drives the threaded rod 17 to rotate. When the threaded rod 17 rotates, because the threaded block 18 and the threaded rod 17 are connected by threads, the threaded block 18 will move as the threaded rod 17 rotates. When the threaded block 18 moves, it will drive one end of the connecting rod 19 to move, thereby adjusting the height of the other end of the connecting rod 19, which in turn drives the feed plate 20 to adjust its angle.
