Description

Technical Field

[0001] This utility model relates to the field of rock and soil screening technology, and in particular to a vibration device for anti-clogging screening of rock and soil particle size distribution. Background Technology

[0002] The particle size distribution of soil and rock refers to the proportion or distribution of particles of different sizes in soil and rock. Soil and rock are composed of particles of different sizes, which can be divided into different particle groups according to their size. Particle size distribution describes the relative content of these different particle groups in soil and rock.

[0003] With the continuous expansion of the construction scale of roads, bridges, buildings and water conservancy projects, accurate determination of soil particle size distribution has become the key to design basis, selection of filling materials and assessment of foundation stability. At this time, a soil particle size distribution screening device is needed to ensure the accuracy, reliability and comparability of the test results.

[0004] Currently, most rock and soil particle size distribution screening equipment on the market consists of a shell, a feed inlet, a screen, and a discharge hopper. The rock and soil to be screened are fed into the device through the feed inlet, and the screen then filters them. The screened rock and soil are discharged through the discharge inlet, thus achieving the particle size distribution screening process. However, in actual use, because the rock and soil particles consist of various sizes, the device requires multiple screenings, resulting in a long screening process. To solve this problem, existing technologies use multi-stage screens to perform multi-stage screening of the rock and soil entering the device, thereby accelerating the screening speed. However, during use, the irregular shapes of the rock and soil particles easily get stuck in the screen holes, causing screen blockage and making it difficult for subsequent particles to pass through, reducing the screening efficiency of the device and failing to meet the user's needs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a vibration device for preventing clogging during the screening of soil and rock particle size distribution, which aims to improve the problem of screen clogging during the use of existing soil and rock particle size distribution screening equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vibration device for screening and preventing clogging of soil and rock particle size distribution, comprising a housing, a motor fixedly connected to the lower left side of the housing, the output end of the motor passing through the housing and fixedly connected to a turntable, a support column fixedly connected to the bottom right side of the turntable, a movable plate provided in the lower inner side of the housing, a groove provided on the left side of the movable plate, the support column being slidably connected to the inner side of the groove, support plates fixedly connected to the front and rear ends of the movable plate, two screens fixedly connected to adjacent sides of the two support plates, a baffle fixedly connected to the lower inner side of the housing, and a rotating mechanism provided in the top inner side of the housing, the rotating mechanism being used to facilitate and accelerate the screening of soil and rock particles.

The bottom of the fixed rod passes through the two sleeves and the two screens in sequence. The right side of the inside of the two sleeves is fixedly connected to a plug block. The two plug blocks are slidably connected to the corresponding curved grooves. The bottom of the left and right sides of the two sleeves are rotatably connected to scrapers. The outer wall of the two sleeves is provided with a thrust assembly.

[0009] As a further description of the above technical solution:

[0010] The thrust assembly includes hollow tubes, and multiple hollow tubes are rotatably connected to the top left and right sides of the corresponding sleeves. Springs are fixedly connected to the top inner sides of the multiple hollow tubes, and sliding rods are fixedly connected to the bottom ends of the multiple springs. The bottom ends of the multiple sliding rods are fixedly connected to the corresponding scrapers.

[0011] As a further description of the above technical solution:

[0012] The inner dimensions of the box are matched with the size of the screen, and the inner dimensions of the box are matched with the size of the baffle.

[0013] As a further description of the above technical solution:

[0014] The inner bottom of the box is fixedly connected to slide rails at both the front and rear ends, and the inner sides of the two slide rails are slidably connected to the corresponding support plates.

[0015] As a further description of the above technical solution:

[0016] A connecting pipe is connected to the top left side of the box, and a feed hopper is connected to the top of the connecting pipe.

[0017] As a further description of the above technical solution:

[0018] The left side of the box is connected to a first discharge port, the top right side of the box is connected to a second discharge port, and the bottom right side of the box is connected to a third discharge port.

[0019] As a further description of the above technical solution:

[0020] An observation window is provided on the front side of the box, and support legs are fixedly connected to the four corners of the bottom of the box.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the motor drives the turntable to rotate, and the support column moves in a circular motion accordingly.

[0032] 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.

[0033] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a vibration device for anti-clogging screening of soil particle size distribution, comprising a housing 1. A motor 3 is fixedly connected to the lower left side of the housing 1. The output end of the motor 3 passes through the housing 1 and is fixedly connected to a turntable 4. The motor 3 drives the turntable 4 to rotate. A support column 5 is fixedly connected to the bottom right side of the turntable 4. The turntable 4 drives the support column 5 to perform circular motion. A movable plate 6 is provided in the lower inner side of the housing 1. A groove 7 is provided on the left side of the movable plate 6. The support column 5 is slidably connected to the inner side of the groove 7. The support column 5 can push the movable plate 6 up and down through the groove 7. The reciprocating motion is achieved by connecting support plates 8 to both the front and rear ends of the movable plate 6. Two screens 9 are fixedly connected to adjacent sides of the two support plates 8. The movable plate 6 can drive the screens 9 to move through the support plates 8. A baffle 10 is fixedly connected to the lower middle part of the inner side of the box 1. A rotating mechanism 2 is provided on the top inner side of the box 1. The rotating mechanism 2 is used to facilitate and accelerate the screening of soil and rock particles. The inner dimensions of the box 1 match the size of the screens 9 and the size of the baffle 10, so that there are no gaps between the screens 9 and the baffle 10 and the box 1.

[0034] Specifically, when using this device to screen soil and rock particles, the motor 3 starts and drives the turntable 4 to rotate. As the turntable 4 rotates, the support column 5 also moves in a circular motion. The support column 5, through the groove 7 on the movable plate 6, can push the movable plate 6 to move up and down reciprocally. During the up and down movement of the movable plate 6, the support plate 8 can drive the two layers of screens 9 to move up and down reciprocally, ensuring that the screens 9 are not blocked by soil and rock particles. At the same time, since the two layers of screens 9 have different pore sizes, they can effectively separate soil and rock particles according to their particle size, improving the practicality of the device and meeting the needs of users.

[0035] Reference Figure 2 , Figure 5 and Figure 6 The rotating mechanism 2 includes a fixed rod 201, which is fixedly connected to the middle of the top inner side of the housing 1. Curved grooves 202 are provided on both the upper and lower sides of the outer wall of the fixed rod 201. Sleeves 203 are rotatably connected to the tops of the two screens 9, allowing the screens 9 to move. The bottom end of the fixed rod 201 passes through the two sleeves 203 and the two screens 9 sequentially. Insertion blocks 204 are fixedly connected to the right side of the inside of each of the two sleeves 203, allowing the sleeves 203 to move. The two insertion blocks 204 are slidably connected to the corresponding curved grooves 202. When the insertion blocks 204 move, they can move through the curved grooves 202. The sleeve 203 is rotated, and scrapers 205 are rotatably connected to the bottom left and right sides of both sleeves 203. The sleeves 203 will drive the scrapers 205 to rotate. The outer walls of both sleeves 203 are provided with thrust components, which include hollow tubes 206. Multiple hollow tubes 206 are rotatably connected to the top left and right sides of the corresponding sleeves 203. Springs 207 are fixedly connected to the top inner side of multiple hollow tubes 206. Slide rods 208 are fixedly connected to the bottom of multiple springs 207. The bottom of multiple slide rods 208 are fixedly connected to the corresponding scrapers 205. The springs 207 can push the scrapers 205 to rotate through the slide rods 208.

[0036] Specifically, when using this device, when the screen 9 vibrates up and down, it will cause the sleeve 203 to move up and down accordingly. The sleeve 203 will further drive the insertion block 204 to move. During the movement of the insertion block 204, due to the restriction of the curved groove 202, the movement trajectory of the insertion block 204 will be converted into rotational motion, which will cause the sleeve 203 to rotate as well, thereby driving the scraper 205 to rotate. This allows the soil particles to be more evenly distributed on the screen 9, avoiding particle accumulation and significantly improving the screening speed of the screen 9. In addition, through the synergistic action of the spring 207 and the slide bar 208, it can be ensured that the scraper 205 can be tightly attached to the filter screen while rotating, further enhancing the screening effect and improving the screening efficiency of the device.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The inner bottom of the box 1 is fixedly connected to the front and rear ends of the slide rails 11. The inner sides of the two slide rails 11 are slidably connected to the corresponding support plates 8. The slide rails 11 can limit the movement of the support plates 8. The top left side of the box 1 is connected to the connecting pipe 12, and the top end of the connecting pipe 12 is connected to the feed hopper 13.

[0038] Specifically, the slide rail 11 limits and supports the support plate 8, and the feed hopper 13 makes it easier for workers to put soil particles into the device.

[0039] Reference Figure 1 and Figure 2 The left side of the box 1 is connected to the first discharge port 14, the top right side of the box 1 is connected to the second discharge port 15, and the bottom right side of the box 1 is connected to the third discharge port 16. The multiple discharge ports are distributed to output rock and soil particles of different sizes. An observation window 17 is opened on the front side of the box 1, and support legs 18 are fixedly connected to the four corners of the bottom of the box 1.

[0040] Specifically, the first discharge port 14, the second discharge port 15 and the third discharge port 16 are used to output soil and rock particles of different sizes, and the observation window 17 allows the staff to observe the screening process of the device. The support leg 18 can be used to provide support for the device.

[0041] Working principle: When using this device to screen soil and rock particles, the motor 3 drives the turntable 4 to rotate. When the turntable 4 rotates, it drives the support column 5 to move in a circular motion. The support column 5 pushes the movable plate 6 to move up and down through the groove 7. The movable plate 6 then drives the two layers of screens 9 to move up and down through the support plate 8, so that the soil and rock particles will not clog the screens 9. In addition, the two layers of screens 9 are designed with different apertures, so that soil and rock particles of different sizes can be screened out at the same time.

[0042] Furthermore, when using this device, the screen 9 vibrates up and down, which drives the sleeve 203 to move up and down. The sleeve 203 then drives the insertion block 204 to move. When the insertion block 204 moves, it is limited by the curved groove 202, which causes the sleeve 203 to rotate. The sleeve 203 then drives the scraper 205 to rotate, so that the soil particles can be evenly distributed on the screen 9 and will not accumulate, thereby increasing the screening speed of the screen 9. In addition, the spring 207 can push the scraper 205 to rotate through the slide rod 208, so that the scraper 205 can stick tightly to the filter screen.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
