Description
Technical Field
[0001] This utility model relates to the field of construction materials technology, and in particular to a vibrating screen sorter for conveying construction materials. Background Technology
[0002] Construction materials are indispensable in urbanization, including cement, sand, gravel, and concrete. To ensure the quality of these materials, vibratory sorters are used for fine screening. This process sorts materials according to their particle size, allowing those that meet the size requirements to proceed to the next stage of construction and ensuring construction quality.
[0003] Existing vibrating separators mostly use the rotation of a cam to drive the entire device to vibrate, thereby achieving a screening effect. Although this can meet the screening needs of most construction materials, the noise is relatively loud during use because the entire device vibrates, which can easily damage the hearing of workers. Furthermore, after long-term use, the screen surface is prone to clogging, resulting in a reduction in the effective screen area.
[0004] Therefore, the existing vibrating separators, which use a whole-body vibrating screening method, generate a lot of noise, which can easily damage the hearing of workers. Furthermore, after long-term use, the screen surface is prone to clogging, resulting in a reduction in the effective screen area. This utility model can generate strong vibration only on the screen plate by using a cylinder to drive the movable rod and the pressure block, as well as the cooperation between the movable rod and the impact plate. This can effectively promote the screening of materials and reduce the generation of noise. Utility Model Content

[0022] 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.
[0023] Please see Figures 1-5 This utility model provides an embodiment of a vibrating screen sorter for conveying construction materials, comprising a mounting housing 1, a pressure top block 603, and an anti-clogging scraping assembly. Two connecting ear plates 2 are symmetrically fixed to the side end face of the mounting housing 1. A suspension spring 3 is installed at the upper end of the two connecting ear plates 2. An overlapping plate 4 is connected to the upper end of the suspension spring 3. Two limiting grooves 5 are symmetrically opened on the side end face of the mounting housing 1. The overlapping plate 4 is slidably connected to the inside of the limiting groove 5. A screen plate 6 is fixed to the side end of the overlapping plate 4. The screen plate 6 is disposed inside the mounting housing 1. A material feeding slide plate 7 is provided below the screen plate 6. A material inlet 8 is opened at the upper end of the mounting housing 1. Two positioning track plates 601 are fixed to the inner walls of both sides of the mounting housing 1. Movable rods 602 are slidably connected inside the two positioning track plates 601. Two pressure top blocks 603 are fixed to the upper end of the movable rods 602.
[0024] Extended inner support plates 604 are fixedly connected to both ends of the inner wall of the housing 1. A movable push rod 605 is slidably connected inside the extended inner support plate 604. An impact plate 606 is fixedly connected to the upper end of the movable push rod 605, and a lower protrusion 607 is fixedly connected to the lower end of the movable push rod 605. When the movable rod 602 drives the pressure block 603 to move, it will contact the lower protrusion 607 and push the movable push rod 605 upward, so that the impact plate 606 impacts the screen plate 6, which has a vibration effect on the screen plate 6.
[0025] A return spring 608 is sleeved on the outside of the movable top rod 605. The upper end of the return spring 608 is connected to the bottom end of the extended inner support plate 604, and the lower end of the return spring 608 is connected to the upper end of the lower protrusion 607. A connecting cross plate 609 is fixed between the two movable rods 602. When the pressure block 603 moves away from the lower protrusion 607, the return spring 608 resets the movable top rod 605.
[0026] A mounting bracket 610 is fixedly connected to the side end of the mounting housing 1. A cylinder 611 is installed on the side end of the mounting bracket 610. The output end of the cylinder 611 passes through the mounting bracket 610 and is fixedly connected to the side end of the connecting horizontal plate 609. When the cylinder 611 is working, it can push the connecting horizontal plate 609, and then drive the movable rod 602 to slide in the positioning track plate 601, so that the pressure top block 603 applies intermittent pressure to the screen plate 6.
[0027] A blower pump 612 is installed on the side end of the mounting housing 1. The output pipe of the blower pump 612 is connected to an air nozzle plate 613. The air nozzle plate 613 is located inside the mounting housing 1. The blower pump 612 delivers air to the air nozzle plate 613 through the pipe. The air nozzle plate 613 blows air onto the feed slide plate 7 to speed up the flow of materials on the feed slide plate 7.
[0028] The anti-clogging scraping assembly includes an upper extension plate 101, a motor 102, a lead screw 103, a movable sleeve 104, a connecting rod 105, and a screen scraping brush 106. The upper extension plate 101 is fixedly connected to the upper end of the mounting housing 1, and the motor 102 is installed on the side end of the upper extension plate 101. The output shaft of the motor 102 passes through the upper extension plate 101 and is fixedly connected to the lead screw 103. The motor 102 drives the lead screw 103 to rotate.
[0029] The outer end of the lead screw 103 is threaded with a movable sleeve 104. The lower end of the movable sleeve 104 is fixed with a connecting rod 105. The side end of the connecting rod 105 is fixed with a screen scraper brush 106. The movable sleeve 104 threaded with the outer end of the lead screw 103 will move linearly along the lead screw 103. The movable sleeve 104 drives the screen scraper brush 106 to move on the surface of the screen plate 6 through the connecting rod 105, scraping off the material accumulated on the screen plate 6.
[0030] Working principle: According to Figures 1-4 First, the construction materials enter the equipment through the feed port 8 at the top of the housing 1 and fall onto the screen plate 6. Then, the cylinder 611 on the support frame 610 pushes the connecting horizontal plate 609, causing the movable rod 602 to slide within the positioning track plate 601, so that the pressure block 603 intermittently applies pressure to the lower protrusion 607. Then, the lower protrusion 607 pushes the movable rod 605 upward, causing the impact plate 606 to impact the screen plate 6 and generate vibration. Under the vibration of the screen plate 6, the material that meets the screen hole size passes through the screen plate 6 and falls onto the discharge slide plate 7 below, and then is discharged from the equipment along the discharge slide plate 7. The material that does not meet the screen hole size is discharged through the screen plate 6. At the same time, during the discharge process of the discharge slide plate 7, the blower pump 612 delivers air to the air nozzle plate 613 through the pipeline. The air nozzle plate 613 blows air down the discharge slide plate 7 to accelerate the flow speed of the material on the discharge slide plate 7.
[0031] according to Figure 5 Finally, the motor 102 drives the lead screw 103 to rotate. The movable sleeve 104, which is threaded to the outer end of the lead screw 103, will move linearly along the lead screw 103. The movable sleeve 104 drives the screen scraper 106 to move on the surface of the screen plate 6 through the connecting rod 105, scraping off the material accumulated on the screen plate 6 and preventing the screen plate 6 from becoming clogged.
[0032] It should be noted that the cylinder 611, blower pump 612 and motor 102 mentioned above can be powered by existing operating techniques. Whether the power supply is provided by a power supply unit or by an external wire, it is all a conventional operating technique and will not be described in detail here.
[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
