Description

Technical Field

[0001] This utility model belongs to the field of recycled stone screening technology, and in particular relates to a recycled stone screening device that is easy to adjust. Background Technology

[0002] An easily adjustable recycled stone screening device comprises multi-layer screening modules and an adjustable parameter mechanism. The screen angle, aperture, and number of layers can be adjusted manually or electrically to accommodate different particle size requirements. Equipped with a variable frequency drive system, it can dynamically adjust the vibration frequency and amplitude to optimize screening accuracy and efficiency. The modular design allows for quick replacement of screen materials (such as polyurethane and stainless steel) to adapt to complex materials such as sand, gravel, and construction waste. The entire machine employs an intelligent control system that allows for preset screening modes and real-time monitoring of operating status. It combines high efficiency, flexibility, and energy-saving and environmentally friendly characteristics, making it suitable for recycled aggregate production, road substrate processing, and other fields.

[0003] According to a public disclosure (Publication No.: CN222241289U), an easily adjustable recycled stone sorting device includes a support frame. Feed hoppers are fixedly connected to both sides of the inner wall of the support frame. Two long plates are fixedly connected to the inner wall of the support frame. A second round rod is fixedly connected to the bottom edge of each of the two long plates. One end of the second round rod is movably connected to a swing rod, and one end of the swing rod is movably connected to an L-shaped plate. This invention uses the output of a motor to drive the entire circular shaft to rotate clockwise. Simultaneously, the rotation of the two circular shafts drives the rotation of two hollow plates. At the same time, the connecting rod also moves in a circular motion with the two hollow plates, and the movement of the connecting rod drives the rotation of the entire hollow column. This allows recycled stones to be sorted according to different specifications, saving time and labor, reducing labor costs, and improving the working efficiency of the recycled stone sorting device.

[0004] In the aforementioned application, the interaction of components such as the swing rod II and the L-shaped plate II results in incomplete screening of recycled stones during screening, and the effect of uniformly placing the screened material is not ideal. Therefore, we propose a recycled stone screening device that is easy to adjust. Utility Model Content

[0005] The purpose of this invention is to provide an easily adjustable recycled stone screening device, which solves the existing problems through a screen box shaking mechanism and a discharge mechanism.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an easily adjustable recycled stone screening device, including a support with rollers fixedly connected to the bottom, a feed box fixedly connected to the top of the support, a telescopic rod fixedly connected inside the support, a connecting rod fixedly connected to one end of the telescopic rod, a connecting rod fixedly connected to one end of the connecting rod, a screen box two fixedly connected inside the support, a discharge box fixedly connected inside the support, and a discharge mechanism provided on the side of the discharge box;

[0008] The discharge mechanism includes a motor, the bottom of which is fixedly connected to the side of the bracket. The output shaft of the motor is fixedly connected to a threaded rod. One end of the threaded rod is rotatably connected to a limit block. The side of the limit block is fixedly connected to the side of the bracket. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A discharge plate is fixedly connected to the circumferential surface of the threaded sleeve. A pulley is fixedly connected to the end of the threaded rod near the motor.

[0009] Furthermore, the side of the bracket is provided with a sliding groove, and the side of the discharge plate is slidably connected to the inside of the sliding groove. There are two sliding grooves, which are symmetrical to each other along the vertical central axis of the discharge box to ensure that the discharge plate runs stably on the specified trajectory and achieves the effect of material discharge of the device.

[0010] Furthermore, the bottom of the discharge box is provided with a discharge port, and the side of the limiting block is located at the right end of the discharge port, so that when the discharge plate moves to the right end, the material is completely discharged.

[0011] Furthermore, the number of telescopic rods and connecting rods is set to several, and they are symmetrical about each other along the vertical central axis of the screen box, so as to achieve the purpose of keeping the screen box in a stable state.

[0012] Furthermore, a screen box shaking mechanism is provided on the side of the first screen box. The screen box shaking mechanism includes a limiting sleeve, the side of which is fixedly connected to the side of the support. A belt is provided on the circumference of the first pulley, and a second pulley is connected to the circumference of the first pulley via belt drive. An eccentric shaft is fixedly connected to the side of the second pulley. A slide rail is provided on the inner side of the support. A slider is fixedly connected to the side of the first screen box, and the side of the slider is slidably connected to the inside of the slide rail. This realizes that the rotation of the second pulley's circular shaft is converted into linear motion by the eccentric shaft under the constraint of the slide rail.

[0013] Furthermore, the slide rails and sliders are provided in pairs and are symmetrical about each other along the vertical central axis of the screen box, which improves the stability of the displacement of the screen box.

[0014] Furthermore, the size of the first screen box is smaller than that of the second screen box, and the size of the discharge box is larger than that of the second screen box, so that the second screen box can completely hold the material screened by the first screen box.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model utilizes the cooperation of components such as threaded rods and threaded sleeves within the discharge mechanism. The circumferential rotation of the threaded rod drives the threaded sleeve to perform horizontal linear motion, which in turn drives the discharge plate to perform horizontal linear motion, thus achieving the effect of horizontal linear motion of the discharge plate. The side of the bracket is provided with a sliding groove, which enables the discharge plate to run along a specified trajectory. The position of the discharge plate can be flexibly adjusted to achieve the best discharge effect, thereby improving the adaptability and flexibility of the device.

[0017] 2. This utility model utilizes the cooperation of components such as the second pulley and the eccentric shaft inside the shaking mechanism of the sieve box. The circumferential rotation of the second pulley drives the circumferential rotation of the eccentric shaft. The circumferential rotation of the eccentric shaft drives the first sieve box to move vertically under the constraint of the slide rail. Under the action of the telescopic rod and the connecting rod, the first sieve box, driven by the rotation of the eccentric shaft, achieves the purpose of shaking and screening, allowing the stones to tumble and vibrate fully inside the first sieve box, ensuring that stones of different sizes can be accurately separated through the screen, thus improving screening accuracy and effect.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model is an easily adjustable recycled stone screening device, including a support 1, a roller 2 fixedly connected to the bottom of the support 1, a feed box 3 fixedly connected to the top of the support 1, a telescopic rod 4 fixedly connected inside the support 1, a connecting rod 5 fixedly connected to one end of the telescopic rod 4, one end of the connecting rod 5 fixedly connected to the side of the first screen box 6, a second screen box 7 fixedly connected inside the support 1, a discharge box 8 fixedly connected inside the support 1, and a discharge mechanism 9 provided on the side of the discharge box 8;

[0029] The material discharge mechanism 9 includes a motor 91, the bottom of which is fixedly connected to the side of the bracket 1. The output shaft of the motor 91 is fixedly connected to a threaded rod 92. One end of the threaded rod 92 is rotatably connected to a limit block 93. The side of the limit block 93 is fixedly connected to the side of the bracket 1. A threaded sleeve 94 is threadedly connected to the circumferential surface of the threaded rod 92. A material discharge plate 95 is fixedly connected to the circumferential surface of the threaded sleeve 94. A pulley 96 is fixedly connected to the end of the threaded rod 92 near the motor 91.

[0030] The side of the support 1 is provided with a sliding groove 97, and the side of the discharge plate 95 is slidably connected to the inside of the sliding groove 97. There are two sliding grooves 97, which are symmetrical to each other along the vertical central axis of the discharge box 8 to ensure that the discharge plate 95 runs stably on the specified trajectory and achieves the effect of the device discharging material.

[0031] The bottom of the discharge box 8 is provided with a discharge port, and the side of the limiting block 93 is located at the right end of the discharge port, so that when the discharge plate 95 moves to the right end, the material is completely discharged.

[0032] The number of telescopic rods 4 and connecting rods 5 is set to be several, and they are symmetrical about each other along the vertical central axis of the screen box 6, so as to achieve the purpose of keeping the screen box 6 in a stable state.

[0033] A screen box shaking mechanism 10 is provided on the side of the screen box 6. The screen box shaking mechanism 10 includes a limit sleeve 101, the side of which is fixedly connected to the side of the bracket 1. A belt 102 is provided on the circumference of the pulley 96. A pulley 103 is connected to the circumference of the pulley 96 via the belt 102. An eccentric shaft 104 is fixedly connected to the side of the pulley 103. A slide rail 105 is provided on the inner side of the bracket 1. A slider 106 is fixedly connected to the side of the screen box 6. The side of the slider 106 is slidably connected to the inside of the slide rail 105. This realizes that the screen box 6, under the restriction of the slide rail 105, converts the rotation of the circular shaft of the pulley 103 into linear motion through the eccentric shaft 104.

[0034] There are two slide rails 105 and two sliders 106, which are symmetrical about each other along the vertical central axis of the screen box 6, thus improving the stability of the displacement of the screen box 6.

[0035] The size of screen box 6 is smaller than that of screen box 7, and the size of discharge box 8 is larger than that of screen box 7, so that screen box 7 can completely hold the material screened by screen box 6.

[0037] When it is necessary to start the screen box shaking mechanism 10 and the discharge mechanism 9, the operator can remotely start the motor 91 to drive the threaded rod 92 to rotate. The rotation of the threaded rod 92 drives the threaded sleeve 94 to move horizontally in a straight line under the action of the limit block 93. The horizontal linear movement of the threaded sleeve 94 drives the discharge plate 95 to move horizontally in a straight line. Under the restriction of the slide 97, the discharge plate 95 can move horizontally in a straight line on the specified trajectory.

[0038] When the threaded rod 92 rotates, it drives the first pulley 96 to rotate. Under the action of the belt 102, it drives the second pulley 103 to rotate. The rotation of the second pulley 103 drives the eccentric shaft 104 to rotate. Through the slider 106 and the restriction of the slide rail 105, the screen box 6 achieves the purpose of vertical linear movement, realizing the shaking effect of the screen box 6.
