Description

Technical Field

[0001] This utility model relates to the field of raw material screening equipment, and in particular to screening equipment for concrete construction raw materials. Background Technology

[0002] In the process of concrete construction, the screening of raw materials is one of the key steps to ensure the quality of concrete. However, traditional screening methods often suffer from low efficiency and poor continuity, which seriously affects the construction progress and concrete production efficiency.

[0003] In practical use, traditional screening equipment usually adopts a simple vibrating screening method. However, when processing large quantities and diverse construction materials, this method often results in problems such as incomplete screening and screen hole blockage, leading to low screening efficiency. This cannot meet the needs of modern concrete construction for efficient and continuous operation and urgently needs to be improved, thus making it difficult to achieve efficient and continuous screening operations.

[0004] Therefore, to address the aforementioned problem of inconvenience in achieving efficient and continuous screening operations, a concrete construction material screening device can be designed. A vibrating motor is activated to generate high-frequency vibration in the screening plate, screening the construction materials for sand and gravel. Simultaneously, connecting springs utilize their elastic deformation to generate rebound force, moving the screening plate up and down to enhance the screening effect. Furthermore, multiple sets of cleaning rods installed below are inserted into the screening holes of the screening plate to effectively prevent sand and gravel from clogging it. The screened sand and gravel roll down to the feed inlet inside the fixed cylinder due to the tilt of the screening plate. Then, the drive motor is activated to rotate the screening auger, transporting the sand and gravel to the discharge rack for discharge, thus achieving efficient and continuous screening operations.

Starting the drive motor 101 will drive the drive pulley 103 to rotate via the drive shaft 102, and the drive pulley 103 will then drive the transmission belt 104 to rotate. The drive assembly also includes a driven shaft 105 and a driven pulley 106. The driven shaft 105 is located inside the screening chamber 1. A driven wheel 106 is provided at one end of the shaft 105. The driven wheel 106 is located inside the transmission belt 104 and is rotatably connected to the transmission belt 104.

[0024] Please see Figures 3-4 In this embodiment, the connecting assembly includes a connecting ring 301 and a connecting rod 302; a connecting ring 301 is provided on the side wall of the drive shaft 102, and two sets of connecting rings 301 are provided, with two sets of connecting rods 302 provided on both sides of the connecting ring 301; when the drive shaft 102 rotates, the two sets of connecting rods 302 are driven to rotate synchronously through the connecting rings 301 on the side wall; the cleaning assembly includes a connecting plate 401 and an adjusting spring 402; a connecting plate 401 is provided at one end of the connecting rod 302, and both ends of the connecting plate 401 are fixedly connected to one end of the connecting rods 302 on both sides, the connecting plate 401...

[0025] When the raw material screening equipment is in use, firstly, the construction raw materials are added into the screening bin 1 through the feeding port 4. Then, the vibration motor 3 is started to make the screening plate 6 vibrate at high frequency to screen the construction raw materials for sand and gravel. At the same time, the connecting spring 8 uses the rebound force generated by its elastic deformation to drive the screening plate 6 to move up and down to enhance the screening effect.

[0026] Furthermore, multiple sets of cleaning rods 10 are inserted into the screening holes of the screening plate 6 to effectively prevent sand and gravel from clogging the screening plate 6. The screened sand and gravel roll down to the feed inlet 14 in the fixed cylinder 13 due to the tilt of the screening plate 6. Then, the drive motor 11 is started to drive the screening auger 12 to rotate and transport the sand and gravel to the discharge rack 15 for discharge, thereby achieving efficient and continuous screening operation.

[0028] Meanwhile, when the drive shaft 102 rotates, it drives the two sets of connecting rods 302 and the connecting plate 401 to rotate synchronously through the connecting ring 301 on the side wall. The multiple sets of adjusting springs 402 on the connecting plate 401 use the rebound force generated by their elastic deformation to make the mounting plate 403 and the cleaning brush 404 on its side wall stick tightly to the surface of the screening plate 6. As the connecting plate 401 rotates, the cleaning brush 404 continuously brushes across the screening plate 6, effectively cleaning away the sand and gravel attached to the surface of the screening plate 6, ensuring the screening effect and the continuous and efficient operation of the equipment.

[0029] Through the above steps, when the raw material screening equipment is in use, firstly, the construction raw materials are added into the screening chamber 1 through the feeding port 4. Then, the vibration motor 3 is started, causing the screening plate 6 to vibrate at high frequency to screen the construction raw materials for sand and gravel. At the same time, the connecting spring 8 uses the rebound force generated by its elastic deformation to drive the screening plate 6 to move up and down, enhancing the screening effect. In addition, multiple sets of cleaning rods 10 set below are inserted into the screening holes of the screening plate 6 to effectively prevent sand and gravel from clogging the screening plate 6. The screened sand and gravel roll down to the feed port 14 in the fixed cylinder 13 due to the tilt of the screening plate 6. Then, the drive motor 11 is started to drive the screening auger 12 to rotate, conveying the sand and gravel to the discharge rack 15 for discharge, thereby achieving efficient and continuous screening operation. In addition, the stirring component can prevent the raw materials from piling up, and the cleaning component can effectively clean the sand and gravel attached to the surface of the screening plate 6, ensuring the screening effect and the continuous and efficient operation of the equipment.
