Description
Technical Field
[0001] The utility model relates to the technical field of screening equipment, in particular to steel slag screening equipment for highway construction. Background Art
[0002] Steel slag refers to the solid waste produced in the steel production process, mainly composed of iron oxide, lime, silicate and other components. It is usually produced after cooling and solidification. The processed and screened steel slag can be used in highway construction. Therefore, the screening machine is one of the important processing equipment for the reuse of steel slag.
[0003] In the prior art, the screening machine is mainly composed of a bracket with a spring, a screening box installed on the spring, and a vibration motor that drives the screening box to shake. When screening the slag, the vibration motor is started. After the slag is poured into the screening box, the screening box will continue to shake with the cooperation of the spring and the vibration motor, thereby speeding up the screening of the slag.
[0004] The above-mentioned and prior arts have the following defects: when steel slag is screened during highway construction, the size of the steel slag after screening by the screening machine is affected by the size of the screening holes on the surface of the screening box. Since the structure of the screening holes on the screening box is fixed, it is difficult to quickly adjust the size of the screening holes as needed, which makes it inconvenient to obtain steel slag of appropriate size, thereby reducing the practicability of the screening machine.
[0005] Therefore, a steel slag screening device for highway construction is proposed. Utility Model Content

[0013] Preferably, a baffle is fixedly connected to the inner wall of the screening box, and the baffle is slidably connected to the orifice plate.
[0014] The effect achieved by the above components is that the baffle plate can shield above the orifice plate to prevent the steel slag from being stuck between the orifice plate and the screening box.

[0019] Preferably, a pedal rod is fixedly connected to the outer wall of the central frame.
[0020] The effect achieved by the above components is: when the pedal rod is stepped on downward, the pedal rod will drive the central frame to rotate downward, and the pedal rod can facilitate the rotation of the central frame.

DETAILED DESCRIPTION
[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0033] like Figure 1-Figure 6 As shown, the utility model provides a slag screening device for highway construction, including a bracket 1, a spring 2 is fixedly connected to the surface of the bracket 1, a screening box 3 is fixedly connected to the upper end of the spring 2, a vibration motor 4 is fixedly connected to the side wall of the screening box 3, an adjustment structure 5 is provided on the inner wall of the screening box 3, and a centralized structure 6 is provided on the surface of the bracket 1.
[0034] The specific settings and functions of the adjustment structure 5 and the centralized structure 6 are described in detail below.
[0035] like Figure 3 and Figure 4 as well as Figure 5 As shown, the adjustment structure 5 includes a perforated plate 51, which is slidably connected to the inner wall of the screening box 3, and the outer wall of the screening box 3 is rotatably connected to a screw rod 52, and the arc surface of the screw rod 52 is threadedly connected to an L-shaped plate 53, and the L-shaped plate 53 is slidably connected to the screening box 3, and the L-shaped plate 53 is fixedly connected to the perforated plate 51, and the end of the screw rod 52 away from the screening box 3 is fixedly connected to a clamping plate 54, and the arc surface of the screw rod 52 is slidably connected to a rotating plate 55, and the size of the clamping plate 54 is adapted to the size of the rotating plate 55. The rotating plate 55 is slid along the arc surface of the screw rod 52 so that the rotating plate 55 is engaged with the clamping plate 54, and then the rotating plate 55 is rotated. The rotation of the rotating plate 55 will drive the screw rod 52 to rotate, so that the position of the perforated plate 51 can be adjusted. After the section is completed, the rotating plate 55 is slid again to disengage the rotating plate 55 from the clamping plate 54, thereby preventing the screw rod 52 from rotating due to accidental contact with the rotating plate 55, thereby changing the position of the orifice plate 51. A triangular prism 56 is fixedly connected to the surface of the screening box 3. The triangular prism 56 is slidably connected to the L-shaped plate 53. A scale groove 57 is provided on the inclined surface of the triangular prism 56. The scale groove 57 is used to facilitate the control of the moving distance of the orifice plate 51, thereby facilitating the control of the degree of misalignment between the orifice plate 51 and the screening box 3. A baffle 58 is fixedly connected to the inner wall of the screening box 3. The baffle 58 is slidably connected to the orifice plate 51. The baffle 58 is used to block the top of the orifice plate 51 to prevent the slag from being stuck between the orifice plate 51 and the screening box 3.
[0036] like Figure 2 and Figure 6As shown, the centralizing structure 6 includes a centralizing frame 61, which is rotatably connected to the bracket 1, a strip plate 62 is fixedly connected to the surface of the bracket 1, a slide plate 63 is slidably connected inside the strip plate 62, a top plate 64 is fixedly connected to the upper surface of the slide plate 63, a leaf spring 65 is fixedly connected between the top plate 64 and the strip plate 62, a roller 66 is rotatably connected to the surface of the top plate 64, the roller 66 is slidably connected to the centralizing frame 61, and the roller 66 can reduce the friction between the top plate 64 and the centralizing frame 61, and a pedal rod 67 is fixedly connected to the outer wall of the centralizing frame 61. When the pedal rod 67 is stepped on downward, the pedal rod 67 will drive the centralizing frame 61 to rotate downward, and the pedal rod 67 can facilitate the rotation of the centralizing frame 61.
[0037] The overall working principle is that when screening slag during highway construction, the vibration motor 4 is started, and the vibration motor 4 cooperates with the spring 2 to drive the screening box 3 to vibrate, and then the slag is poured into the screening box 3. At this time, the orifice plate 51 cooperates with the screening box 3 to make the slag with a smaller size slide downward, and the slag with a suitable size will slide along the surface of the orifice plate 51 to the specified position, so that the slag with a suitable size can be obtained. When the size of the screened slag needs to be adjusted, the rotating plate 55 is slid along the arc surface of the screw rod 52 to engage the rotating plate 55 with the clamping plate 54, and then the rotating plate 55 is rotated. The rotation of the rotating plate 55 will drive the screw rod 52 to rotate. When the screw rod 52 rotates, it will drive the L-shaped plate 53 to move with the help of the thread, and the L-shaped plate 53 slides along the inner surface of the screening box 3. The movement will drive the orifice plate 51 to slide. When the orifice plate 51 slides along the screening box 3, it will be misaligned with the screening box 3, thereby changing the size of the steel slag that can pass through the orifice plate 51 and the screening box 3, so that steel slag of different sizes can be easily obtained. In the process of adjusting the position of the orifice plate 51, the scale groove 57 can facilitate the control of the moving distance of the orifice plate 51, thereby facilitating the control of the degree of misalignment between the orifice plate 51 and the screening box 3. The baffle 58 can block the top of the orifice plate 51 to prevent the steel slag from being stuck between the orifice plate 51 and the screening box 3. After the adjustment is completed, the rotating plate 55 is slid again to disengage the rotating plate 55 from the clamping plate 54, thereby preventing the screw rod 52 from rotating due to accidental contact with the rotating plate 55, thereby causing the position of the orifice plate 51 to change.
[0038] When the slag passes through the screening box 3 and falls onto the inner wall of the collecting frame 61, the collecting frame 61 can collect the slag, thereby reducing the scattering range of the slag, making it easier to collect the slag and improving the practicality of the screening machine. When it is necessary to speed up the sliding speed of the slag from the collecting frame 61, step on the pedal 67 downward, the pedal 67 will drive the collecting frame 61 to rotate downward, the collecting frame 61 will squeeze the roller 66, the roller 66 will drive the top plate 64 to slide downward, the roller 66 can reduce the friction between the top plate 64 and the collecting frame 61, the sliding of the top plate 64 will drive the slide plate 63 to slide along the strip plate 62 and compress the leaf spring 65, when the pedal 67 is released, the leaf spring 65 stretches and drives the top plate 64 to slide upward, the sliding of the top plate 64 will cause the roller 66 to lift the collecting frame 61, thereby causing the collecting frame 61 to shake, thereby speeding up the sliding speed of the slag from the collecting frame 61.
[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
