Description

Technical Field

[0001] This utility model belongs to the field of ceramsite sand processing technology, specifically referring to a ceramsite sand screening machine. Background Technology

[0002] Screening is a crucial step in the production of ceramsite sand, aiming to obtain products with different particle size specifications.

[0003] However, existing screening machines have several drawbacks. First, the concentrated feeding method causes ceramsite sand to easily accumulate upon entering the screening area. This accumulation not only hinders the normal flow of materials but also prevents some particles from fully contacting the screen, severely impacting screening efficiency and quality. This results in a large amount of products that do not meet particle size requirements being mixed into qualified products, reducing the overall quality of the product. Second, different batches of ceramsite sand vary in particle size distribution and moisture content. Fixed-angle screens cannot adapt to these changes. When processing ceramsite sand with high moisture content, the inability to adjust the screen angle leads to an unsatisfactory material sliding speed on the screen, easily causing screen blockage. Furthermore, when processing ceramsite sand with unique particle size distributions, fixed-angle screens cannot achieve optimal screening results, making it difficult to guarantee screening accuracy. Utility Model Content

[0004] The technical problem this invention aims to solve is that the feeding method of existing screening machines is relatively concentrated, which reduces the screening effect. At the same time, the screen angle is inconvenient to adjust, making them inconvenient to use.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a ceramsite sand screening machine, including a support frame and a screen plate movably arranged in the support frame, wherein the support frame is a semi-enclosed box-shaped structure with openings on the top and one side;

[0006] It also includes a guide rod set on the top of the support frame, a slider slidably mounted on the guide rod, a receiving hopper fixedly connected to the slider, and a moving component that pushes the receiving hopper to move horizontally connected to the other side of the receiving hopper;

[0007] One end of the support frame is provided with a fixed shaft, the sieve plate is rotatably connected to the fixed shaft, a vibration motor is installed at the bottom of the sieve plate, and the other end of the sieve plate is connected to an adjusting shaft parallel to the fixed shaft. A support component for adjusting the angle of the sieve plate is connected to the adjusting shaft.

[0008] Furthermore, the moving component includes a drive motor and a second slider. The drive motor is mounted on the side wall of the support frame, and the output end of the drive motor is provided with a reciprocating lead screw arranged parallel to the guide rod. The second slider is fixed to the side wall of the receiving hopper and threadedly connected to the reciprocating lead screw.

[0009] Furthermore, the support assembly includes a support block and an electric push rod. The support block is fixed to the side wall of the support frame and is located away from the fixed axis. The electric push rod is hinged to the top wall of the support block and the adjustment shaft.

[0010] Furthermore, guide grooves are provided on both side walls of the support frame. The guide grooves are arc-shaped and the center of the arc is located on the axis of the fixed shaft. The adjustment shaft passes through the guide grooves.

[0011] Preferably, the bottom wall of the support frame is provided with a material gathering groove with a central recess, and the side wall of the support frame is provided with a discharge port that connects to the bottom end of the material gathering groove.

[0012] The beneficial effects achieved by adopting the above-described structure are as follows:

[0013] 1. By setting guide rods and reciprocating screws, the hopper can be moved back and forth to achieve uniform feeding of ceramsite sand and avoid material accumulation and uneven screening.

[0014] 2. By setting fixed shafts and adjusting shafts to support the screen plate, and in conjunction with guide grooves and electric push rods, the tilt angle of the screen plate can be adjusted to cope with different screening conditions and improve the flexibility of the equipment.

[0022] like Figure 1-4 As shown, this utility model proposes a ceramsite sand screening machine, which includes a support frame 1 and a screen plate 2 movably disposed within the support frame 1. The support frame 1 is a semi-enclosed box-shaped structure with openings on the top and one side. It also includes a guide rod 3 disposed on the top of the support frame 1, a slider 4 slidably disposed on the guide rod 3, a receiving hopper 5 fixedly connected to the slider 4, and a moving component 6 for pushing the receiving hopper 5 to move horizontally connected to the other side of the receiving hopper 5. A fixed shaft 7 is disposed at one end of the support frame 1, the screen plate 2 is rotatably connected to the fixed shaft 7, a vibration motor 8 is installed at the bottom of the screen plate 2, and an adjusting shaft 9 parallel to the fixed shaft 7 is connected to the other end of the screen plate 2. Guide grooves 16 are opened on both side walls of the support frame 1. The guide grooves 16 are arc-shaped and the center of the arc is located on the axis of the fixed shaft 7. The adjusting shaft 9 is disposed through the guide grooves 16, and a support component 10 for adjusting the angle of the screen plate 2 is connected to the adjusting shaft 9.

[0023] Adjust the support component 10 to adjust the screening angle of the screen plate 2, feeding the ceramsite sand into the receiving hopper 5. Start the moving component 6 to move the receiving hopper 5 along the guide rod 3, so that the ceramsite sand is evenly sprinkled above the screen plate 2 along the reciprocating movement of the receiving hopper 5, avoiding material accumulation and uneven screening. At the same time, start the vibration motor 8 to drive the screen plate 2 to vibrate and screen the falling material.

[0024] like Figure 1 and 4As shown, the moving component 6 includes a drive motor 11 and a slider 12. The drive motor 11 is mounted on the side wall of the support frame 1. The output end of the drive motor 11 is provided with a reciprocating screw 13 arranged parallel to the guide rod 3. The slider 12 is fixed to the side wall of the receiving hopper 5 and threadedly connected to the reciprocating screw 13. When the drive motor 11 is started, the reciprocating screw 13 is driven to rotate. The reciprocating screw 13 pushes the slider 12 to move back and forth, thereby adjusting the position of the receiving hopper 5.

[0025] like Figure 4 As shown, the support assembly 10 includes a support block 14 and an electric push rod 15. The support block 14 is fixed to the side wall of the support frame 1 and is located away from the fixed shaft 7. The electric push rod 15 is hinged to the top wall of the support block 14 and the adjusting shaft 9. When the electric push rod 15 is activated, the adjusting shaft 9 is pushed to move along the guide groove 16, thereby adjusting the height of the top of the screen plate 2, and thus adjusting the angle of the screen plate 2, which is convenient for adjusting the screening of different materials.

[0026] like Figure 3 As shown, the bottom wall of the support frame 1 is provided with a centrally recessed material collection trough 17, and the side wall of the support frame 1 is provided with a discharge port 18 that is connected to the bottom of the material collection trough 17, so as to facilitate the collection of the screened material.
