Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a sand screening machine for building engineering. Background Technology

[0002] Sand refers to fine pebbles or things that resemble sand. In the field of construction engineering, concrete is usually the most in-demand and basic material for building construction. Sand is required when preparing concrete, and there are certain requirements for the size of the sand. In addition, sand often contains larger stones, which need to be screened by machines.

[0003] For example, according to authorization announcement number CN222267770U, this utility model relates to the technical field of equipment for construction engineering and discloses a sand screening machine for construction engineering, including a main body and an auxiliary body. The auxiliary body is located above the main body. The main body includes a sand screening machine body, a load-bearing base, and support legs. The load-bearing base is fixedly installed at the lower end of the sand screening machine body, and the support legs are fixedly installed at the lower end of the load-bearing base. The main body also includes an observation glass, a material intake chamber, and a sand screening component. The observation glass is fixedly installed at the front end of the sand screening machine body, the material intake chamber is fixedly located at the front end of the sand screening machine body, and the material intake chamber is fixedly located below the observation glass. The sand screening component is fixedly installed at the inner end of the sand screening machine body. This sand screening machine for construction engineering, by installing the sand screening component, can discharge the screened stones while screening sand, reducing the user's work steps and improving the working efficiency of the equipment.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, although the aforementioned equipment can solve the problem that most existing sand screening machines used in construction projects cannot automatically discharge the screened stones and other impurities to the outside during actual use, requiring users to manually clean them, which reduces the working efficiency of the equipment, during use, although the sand screening device can discharge the stones and other impurities outside the box on its own, it does not have an auxiliary dust removal structure. The collision of sand particles and the vibration of screening will generate a large amount of dust, which will directly escape into the air, forming an unorganized emission. Utility Model Content

This solves the problem that while the sand screening device can discharge impurities such as stones from the box itself, it does not have an auxiliary dust removal structure. The collision of sand particles and the vibration of screening will generate a large amount of dust, which will directly escape into the air, forming an unorganized emission.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sand screening machine for construction engineering, comprising a pad block, a screening box, a fixed plate, a movable plate, and a discharge port. The top of the pad block is fixedly connected to the bottom of the screening box, the front side of the top of the screening box is fixedly connected to the bottom of the fixed plate, the back of the fixed plate is movably connected to the front of the movable plate via a pin, the discharge port is located at the bottom of the front of the screening box, a dust removal frame is movably connected to the bottom of the front of the screening box, electrostatic dust removal rods are movably connected to both sides of the inner wall of the dust removal frame, installation components are fixedly connected to the bottom of both sides of the front of the screening box, and collection components are provided on both sides of the bottom of the inner wall of the dust removal frame.

[0007] As a preferred embodiment of this utility model, the mounting component includes a mounting strip, the back of which is fixedly connected to the bottom of both sides of the front of the screening box, and mounting grooves are provided at the bottom of both sides of the back of the dust removal frame, with the inner wall of the mounting groove slidably connected to the surface of the mounting strip.

[0008] As a preferred embodiment of the present invention, the collecting component includes a through groove, which is formed on both sides of the bottom of the inner wall of the dust removal frame, and a collecting box is movably connected to both sides of the bottom of the dust removal frame.

[0009] As a preferred embodiment of this utility model, mounting blocks are fixedly connected to both the left and right sides of the inner wall of the dust removal frame, and the inner wall of the mounting blocks is engaged with the surface of the electrostatic dust removal rod.

[0010] As a preferred embodiment of this utility model, movable grooves are provided on both sides of the dust removal frame, the movable grooves are opened to both sides of the inner wall of the dust removal frame, movable blocks are slidably connected to the inner wall of the movable grooves, scraper blocks are slidably connected to the surface of the electrostatic dust removal rod, and the outer side of the scraper block is fixedly connected to the inner side of the movable block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a dust removal frame and electrostatic dust removal rods, allows users to easily install the electrostatic dust removal rods on both sides of the discharge port. The electrostatic dust removal rods can then adsorb the dust escaping from the discharge port. This solves the problem that while the sand screening device can discharge stones and other impurities from the box itself, it does not have an auxiliary dust removal structure. The collision of sand particles and the vibration of screening generate a large amount of dust, which will directly escape into the air, forming an unorganized emission. This invention achieves the effect of auxiliary dust removal.

[0015] 2. This utility model, by setting up an installation component, allows the user to connect the dust collector frame to the screening box. First, align the mounting grooves on both sides of the bottom back of the screening box with the top of the mounting strip, then move the dust collector frame downwards so that the mounting strip is completely inside the mounting groove. The mounting strip can restrict the movement direction of the dust collector frame, allowing it to be fixed on the front of the screening box. When the user needs to repair the components inside the dust collector frame, they only need to remove the mounting strip from the mounting groove, thus achieving the effect of assisting in the installation of the dust collector frame.

[0016] 3. By setting up a through groove and a collection box, when the user scrapes off the dust attached to the surface of the electrostatic dust removal rod, the dust floats downwards. The through groove allows the dust to move into the inside of the collection box, and the collection box can then collect the dust, making it easier for the user to clean it later, thus achieving the effect of assisting in dust collection.

[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] like Figures 1 to 4 As shown, the present invention provides a sand screening machine for construction engineering, including a pad block 1, a screening box 2, a fixed plate 3, a movable plate 4, and a discharge port 5. The top of the pad block 1 is fixedly connected to the bottom of the screening box 2. The front side of the top of the screening box 2 is fixedly connected to the bottom of the fixed plate 3. The back of the fixed plate 3 is movably connected to the front of the movable plate 4 through a shaft pin. The discharge port 5 is opened at the bottom of the front of the screening box 2. A dust removal frame 6 is movably connected to the bottom of the front of the screening box 2. Electrostatic dust removal rods 7 are movably connected to both sides of the inner wall of the dust removal frame 6. Installation components 8 are fixedly connected to the bottom of both sides of the front of the screening box 2. Collection components 9 are opened on both sides of the bottom of the inner wall of the dust removal frame 6.

[0024] refer to Figure 3 The mounting component 8 includes a mounting strip 81. The back of the mounting strip 81 is fixedly connected to the bottom of both sides of the front of the screening box 2. The bottom of both sides of the back of the dust removal frame 6 is provided with mounting grooves 82. The inner wall of the mounting groove 82 is slidably connected to the surface of the mounting strip 81.

[0025] As a technical optimization of this utility model, by setting the installation component 8, when the user needs to connect the dust removal frame 6 to the screening box 2, first align the installation grooves 82 on both sides of the bottom back of the screening box 2 with the top of the installation strip 81, and then move the dust removal frame 6 downward so that the installation strip 81 is completely moved into the interior of the installation groove 82. The installation strip 81 can restrict the movement direction of the dust removal frame 6, so that it can be fixed on the front of the screening box 2. When the user needs to repair the internal components of the dust removal frame 6, he / she only needs to remove the installation strip 81 from the installation groove 82, thereby achieving the effect of assisting in the installation of the dust removal frame 6.

[0026] refer to Figure 4 The collection component 9 includes a through groove 91, which is opened on both sides of the bottom of the inner wall of the dust collection frame 6. Collection boxes 92 are movably connected to both sides of the bottom of the dust collection frame 6.

[0027] As a technical optimization of this utility model, by setting a through groove 91 and a collection box 92, when the user scrapes off the dust attached to the surface of the electrostatic dust removal rod 7, the dust floats downwards. The through groove 91 allows the dust to move into the inside of the collection box 92, and the collection box 92 can then collect the dust, making it easier for the user to clean it later, thereby achieving the effect of assisting in dust collection.

[0028] refer to Figure 4 Mounting blocks 10 are fixedly connected to both the left and right sides of the inner wall of the dust removal frame 6. The inner wall of the mounting blocks 10 is engaged with the surface of the electrostatic dust removal rod 7.

[0029] As a technical optimization of this utility model, by setting up the mounting block 10, when the user needs to connect the electrostatic dust removal rod 7 to the dust removal frame 6, one end of the electrostatic dust removal rod 7 is engaged with the inner wall of the mounting block 10, and the other end is engaged with the corresponding mounting block 10. Since the mounting block 10 is fixedly connected to the dust removal frame 6, the electrostatic dust removal rod 7 can be stably placed on both sides of the dust removal frame 6, thereby achieving the effect of assisting in the installation of the electrostatic dust removal rod 7.

[0030] refer to Figure 3 Movable grooves 11 are provided on both sides of the dust removal frame 6. The movable grooves 11 are opened to both sides of the inner wall of the dust removal frame 6. Movable blocks 12 are slidably connected to the inner wall of the movable grooves 11. Scrapers 13 are slidably connected to the surface of the electrostatic dust removal rod 7. The outer side of the scraper 13 is fixedly connected to the inner side of the movable block 12.

[0031] As a technical optimization of this utility model, by setting up a movable groove 11, a movable block 12, and a scraper 13, when the user needs to scrape off the dust on the surface of the electrostatic dust removal rod 7, the movable block 12 is moved downward. Since the movable block 12 is fixedly connected to the scraper 13, the movable block 12 can drive the scraper 13 to move up and down. The movable groove 11 can restrict the movement direction of the movable block 12, making the up and down movement of the movable block 12 more stable. Then, the scraper 13 can be used to scrape off the dust on the surface of the electrostatic dust removal rod 7, thereby achieving the effect of assisting in cleaning the surface of the electrostatic dust removal rod 7.

[0032] refer to Figure 3 Both sides of the inner wall of the movable groove 11 are provided with spring grooves 14. The top of the inner wall of the spring groove 14 is fixedly connected to the limiting rod 15. The surface of the limiting rod 15 is movably sleeved with a spring 16. The top of the surface of the spring groove 14 is slidably connected to the pressure block 17. The inner wall of the pressure block 17 is slidably connected to the surface of the limiting rod 15. The bottom of the pressure block 17 is in contact with one end of the spring 16. The inner side of the pressure block 17 is fixedly connected to both sides of the movable plate 4.

[0033] As a technical optimization of this utility model, by setting a spring groove 14, a limiting rod 15, a spring 16, and a pressure block 17, when the movable block 12 moves downward, the movable block 12 will drive the pressure block 17 to move downward. At this time, the spring 16 will be squeezed downward by the pressure block 17 and contract. The limiting rod 15 can limit the contraction direction of the spring 16 so that it will not be twisted or deformed. The spring groove 14 can limit the movement direction of the pressure block 17 so that its movement is more stable. When the user no longer applies force to the movable block 12, the spring force of the spring 16 can push the movable block 12 back to its original position, thereby achieving the effect of assisting the user in handling the electrostatic dust removal rod 7.

[0034] refer to Figure 4 The bottom of the dust removal frame 6 has connecting grooves 18 on both sides. Connecting blocks 19 are slidably connected to the inner wall of the connecting grooves 18. The bottom of the connecting blocks 19 is fixedly connected to the top of the collection box 92.

[0035] As a technical optimization of this utility model, by setting the connecting groove 18 and the connecting block 19, when the user needs to connect the collection box 92 to the dust removal frame 6, first align the back of the connecting block 19 on the top of the collection box 92 with the connecting groove 18, and then move the collection box 92 in the screening direction 2 so that the connecting block 19 is completely moved into the interior of the connecting groove 18. The connecting groove 18 can restrict the movement direction of the connecting block 19 so that it can be connected to the dust removal frame 6, thereby achieving the effect of assisting the installation of the collection box 92.

[0036] The working principle and usage process of this utility model are as follows: During use, the dust collection frame 6 allows the user to easily install the electrostatic dust removal rods 7 on both sides of the discharge port 5. The electrostatic dust removal rods 7 then adsorb the dust escaping from the discharge port 5. When the user needs to connect the dust collection frame 6 to the screening box 2, first align the mounting grooves 82 on both sides of the bottom back of the screening box 2 with the top of the mounting strip 81, then move the dust collection frame 6 downwards so that the mounting strip 81 is completely inside the mounting groove 82. The mounting strip 81 restricts the movement direction of the dust collection frame 6, allowing it to be fixed to the front of the screening box 2. When the user needs to repair the internal components of the dust collection frame 6, simply detach the mounting strip 81 from the mounting groove. The groove 82 is sufficient. When the user needs to scrape the dust off the surface of the electrostatic dust removal rod 7, the movable block 12 is moved downward. Since the movable block 12 is fixedly connected to the scraper 13, the movable block 12 can drive the scraper 13 to move up and down. The movable groove 11 can restrict the movement direction of the movable block 12, making the up and down movement of the movable block 12 more stable. Then, the scraper 13 can be used to scrape off the dust on the surface of the electrostatic dust removal rod 7. When the user scrapes off the dust attached to the surface of the electrostatic dust removal rod 7, the dust floats downward. The through groove 91 can be used to move the dust into the inside of the collection box 92. The collection box 92 can then collect the dust, making it convenient for the user to clean it later, thereby achieving the effect of auxiliary dust removal.

[0037] In summary, this sand screening machine for construction projects, by incorporating a dust collection frame 6 and electrostatic dust removal rods 7, allows users to easily install the electrostatic dust removal rods 7 on both sides of the discharge port 5. The electrostatic dust removal rods 7 then adsorb the dust escaping from the discharge port 5. This solves the problem that while the sand screening device can automatically discharge stones and other impurities from the casing, it lacks an auxiliary dust removal structure. Consequently, the collision of sand particles and the vibration during screening generate a large amount of dust, which directly escapes into the air, resulting in unorganized emissions.
