[0001] This utility model relates to the field of screening equipment technology, specifically a rock and soil screening equipment for civil engineering and water conservancy construction. Background Technology
[0002] Rock and soil screening, as the name suggests, is the separation of rocks and sand. In the process of material sourcing in industrial production, rocks and sand are often mixed together (explain what rock and soil are, that rock and soil are a mixture of rocks and sand, and in what scenarios rock and soil are generally used). Since the diameters of the two are not the same, it is often necessary to separate them. It is widely used in some fields, especially in civil engineering and water conservancy construction, and is an important process in production activities. In order to facilitate the classification and use of rock and soil, screening equipment is needed to screen the rock and soil.

A sliding block is fixedly connected to the outer wall of the left side of the machine body. A protective shell is fixedly connected to the outer wall of the sliding block. A pull rod is slidably connected through the inside of the protective shell. This device cleans the filter screen by placing a cleaning shell above it. Inside the cleaning shell, a ball connected by a spring is pushed into the filter holes by the reaction force of the spring. This forces the residue to fall off or be squeezed out during a slight shaking, thus cleaning the filter holes, improving the screening effect of the filter screen, and increasing the working efficiency of the device. However, the filter screen in this existing soil and rock screening equipment for civil engineering and water conservancy construction is fixedly installed inside the machine body. After long-term use, the filter screen will be damaged, making it inconvenient to replace the damaged filter screen.

[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] Example 1
[0024] This embodiment provides a soil and rock screening device for civil engineering and water conservancy construction, such as... Figure 1-6 As shown, the soil and rock screening equipment includes a box body 1, a support frame 2 installed in the box body 1 via a groove 101, a screening screen 3 installed in the inner cavity of the support frame 2, a replacement structure 4 slidably installed in the box body 1 via a slide groove 103, a vibrating motor 5 installed on the left side wall of the box body 1, and a feeding box 6 set on the end face of the box body 1.
[0025] The replacement structure 4 includes a slide plate 41 that is slidably mounted on the slide groove 103. An L-shaped plate 42 is mounted on the front of the slide plate 41 and guide rods 43 are symmetrically mounted on the bottom of the slide plate 41. A baffle 44 is mounted on the lower end of the guide rod 43, and a spring 45 is mounted on the baffle 44 and located outside the guide rod 43.
[0026] In use, the operator drives the L-shaped plate 42 to move upward in the second opening 107. The L-shaped plate 42 drives the slide plate 41 to move upward. The slide plate 41 drives the two sets of guide rods 43 to move. The guide rods 43 move the baffle 44 upward. The baffle 44 moves upward from the limiting groove 105 and the slot 21 in sequence. Then, the support frame 2 moves away from the groove 101. The support frame 2, carrying the damaged screening screen 3, is quickly removed from the first opening 102. A new support frame 2 and screening screen 3 are replaced. The support frame 2 drives the screening screen 3 to slide from the first opening 102 into the interior of the box 1, so that the support frame 2 is away from the first opening. One end of 102 moves into the groove 101, and then the L-shaped plate 42 is released. Under the reset action of the two sets of springs 45, the springs 45 drive the baffle 44 to move down. The baffle 44 moves down into the slot 21 and the limiting slot 105 in sequence, thereby realizing the function of quick replacement of the screening screen 3. This function facilitates the quick replacement of the screening screen 3 and avoids the problem that the filter screen of the existing soil and rock screening equipment used in civil engineering and water conservancy construction is fixedly installed inside the machine body. After long-term use, the filter screen will be damaged, making it inconvenient to replace the damaged filter screen. The replacement steps are simple, thereby improving the replacement efficiency of the screening screen 3.
[0027] In this embodiment, a through hole 421 is provided on the L-shaped plate 42, and a fixing knob 46 is installed on the L-shaped plate 42 through the through hole 421. A threaded hole 104 is provided on the front of the housing 1 corresponding to the through hole 421. An installation groove 106 is provided on the housing 1 corresponding to the guide rod 43. The housing 1 is connected to the upper end of the spring 45 through the installation groove 106. The housing 1 is slidably connected to the baffle 44 through the installation groove 106.
[0028] The mechanism is designed with a fixed knob 46 and a threaded hole 104. When the vibrating motor 5 vibrates the housing 1, the baffle 44 may bounce up and down after being vibrated, affecting the installation stability of the support frame 2 and the screening screen 3. By connecting the fixed knob 46 to the threaded hole 104, the L-shaped plate 42 is fixed to the front of the housing 1, thus preventing the baffle 44 from bouncing up and down after being vibrated, thereby improving the installation stability of the screening screen 3.
[0029] In this embodiment, a first opening 102 is provided on the front of the box 1 and corresponding to the support frame 2. A limiting groove 105 is provided on the box 1 and corresponding to the baffle 44. A slot 21 is provided on the support frame 2 and corresponding to the baffle 44. A second opening 107 is provided on the front of the box 1. An L-shaped plate 42 passes through the second opening 107 and extends to the outside of the box 1. A box cover 61 is installed on the unloading box 6 via a hinge. A handle is installed on the end face of the box cover 61. A discharge shell 7 is provided at the lower end of the box 1.
[0030] The L-shaped plate 42 passes through the second opening 107 and extends to the outside of the box 1, making it convenient for the staff to hold the L-shaped plate 42 and drive the baffle 44 to move up and down, so as to realize the function of replacing the screening screen 3.
[0031] Example 2
[0032] Unlike Example 1, the existing soil and rock screening equipment for civil engineering and water conservancy construction lacks a dust removal device, which causes the soil and rock screening equipment to generate a large amount of dust during the screening process and pollute the environment. To address this, a U-shaped pipe 8 is installed on the left side wall of the feeding box 6 through a connection hole. A filter box 9 is installed at the other end of the U-shaped pipe 8 and on the end face of the box body 1. A filter screen 10 is installed inside the filter box 9. An exhaust pipe 11 is installed on the right side wall of the filter screen 10 through a connection hole. A blower 12 is installed at the other end of the exhaust pipe 11.
[0033] When the soil and rock screening equipment is in use, a large amount of dust is generated during the screening of soil and rock. Then, the exhaust fan 12 is started through the control panel. The exhaust fan 12 draws the dusty air from the feed box 6 into the filter box 9 through the U-shaped pipe 8. The air drawn into the filter box 9 passes through the filter screen 10, which filters the dust in the air. The filtered clean air enters the exhaust fan 12 through the exhaust pipe 11 and is then discharged into the environment by the exhaust fan 12. This achieves the function of dust filtration, avoiding the problem that existing soil and rock screening equipment used in civil engineering and water conservancy construction lacks a dust removal device, which causes a large amount of dust to be generated during the screening process and pollutes the environment. This makes the soil and rock screening equipment perform better.
[0034] In this embodiment, a base 13 is installed on the end face of the housing 1, and the exhaust fan 12 is fixedly installed on the end face of the base 13 by bolts.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
