Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a sand screening device for construction engineering. Background Art

[0002] Sand screening usually refers to the work of screening and cleaning sand in places such as rivers, lakes or beaches. This work is usually done to collect useful materials from the sand, such as sand needed for construction projects, or to clean up public places such as beaches. In construction projects, sand screening is an important step because it can help remove impurities in the sand and ensure the quality of construction materials. Sand screening is usually carried out using mechanical equipment, such as screens, vibrating screens, etc., to speed up and improve efficiency. Sand screening work usually requires certain skills and experience, especially in choosing suitable screening equipment, mastering screening technology, and handling screened materials.

[0003] Sand screening in construction is a very important procedure. The particle size of sand is distinguished by the screen, but there are also shortcomings. The existing construction engineering sand screening equipment will screen out the oversized sand and then process it, leaving only part of the usable sand for use in the project, resulting in a large waste of sand and gravel, which greatly increases the investment cost.

[0004] Therefore, it is urgent to provide a construction engineering sand screening device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is that when the existing construction engineering sand screening device is screening sand, only part of the fine sand is put into the construction engineering for use, resulting in a waste of resources and a high overall investment.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a construction engineering sand screening device, comprising a main body, a base frame is fixedly connected to the bottom of the main body, a feeding port is opened on the top of the main body, a screening mechanism is installed inside the main body, and a driving mechanism is installed inside the main body;

[0007] A first discharge pipe is provided on one side of the outer wall of the main body, a sand and gravel channel is opened on the inner wall of the main body, a convergence port is fixedly connected to the inner wall of the main body, a crushing mechanism is installed inside the main body, and a second discharge pipe is opened at the bottom of the main body.

[0008] The utility model is further configured as follows: the screening mechanism includes a support frame fixedly connected to the inner wall of the main body, a screen is fixedly connected inside the support frame, a first fixed seat is fixedly connected to the bottom of the outer wall of the support frame, a spring is fixedly connected to the bottom of the first fixed seat, a second fixed seat is fixedly connected to the bottom of the spring, and the bottom of the second fixed seat is fixedly connected to the inner wall of the main body.

[0009] Through the above technical solution, when in use, the sand to be screened is thrown in from the feed port, and the sand will fall onto the screen inside the support frame. Since the gravity of the sand will compress the spring between the first fixed seat and the second fixed seat, some fine sand will fall from the screen first, and then the gravity will be reduced, and the spring will start to rebound, shaking off the stacked sand, so that the screened sand is discharged from the first discharge pipe, thereby quickly completing the first step of sand screening.

[0010] The utility model is further configured as follows: the driving mechanism includes a first motor fixedly connected to the top of the main body, the output end of the first motor is fixedly connected to a driving shaft, the outer wall of the driving shaft is fixedly connected to a plurality of stirring rods, and the driving shaft runs through the interior of the main body.

[0011] Through the above technical solution, when in use, the first motor on the top of the main body is started to drive the drive shaft to rotate, so that multiple stirring rods begin to rotate, so that the sand on the screen can flow, which can help the sand to be screened. At the same time, the sand and gravel left after screening are stirred to flow into the convergence port through the sand and gravel channel, so that while accelerating the screening, the sand and gravel left after screening can be subjected to the next operation, which greatly improves the screening efficiency.

[0012] The utility model is further configured as follows: the crushing mechanism includes a second motor fixedly connected to the front end of the main body, the output end of the second motor is fixedly connected to a first crushing roller, the outer wall of the rotating shaft on the first crushing roller is fixedly connected to a first gear, the inner wall of the main body is rotatably connected to a second crushing roller, the outer wall of the rotating shaft on the second crushing roller is fixedly connected to a second gear, and the first gear is meshed with the second gear.

[0013] Through the above technical solution, when in use, the crushing mechanism can crush the sand and gravel left after screening so that they can be reused, saving resources. Specifically, when the sand and gravel flow down from the converging port, starting the second motor at the front end of the main body will drive the first gear and the first crushing roller to rotate. Since the first gear is meshed with the second gear, the second crushing roller will be driven to rotate. When the sand and gravel pass between the first crushing roller and the second crushing roller, they will be crushed into fine sand, so that they can be used in the building again.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model can screen the sand during processing by designing a simple screening mechanism, a driving mechanism and a crushing mechanism to improve the overall quality. Other unqualified sand and gravel can be crushed through a channel and put back into the sand for use, thereby greatly improving the utilization efficiency of the sand;

[0016] 2. The utility model has a simple design of driving mechanism and crushing mechanism, which can discharge qualified sand after the first screening, and then stir the sand and gravel through the stick on the driving mechanism, so that the sand and gravel are discharged from the channel to the roller for crushing, and then put into use again, thereby reducing investment costs.

[0023] See also Figure 1-Figure 4A construction engineering sand screening device comprises a main body 1, a bottom of the main body 1 is fixedly connected to a base frame 2, a top of the main body 1 is provided with a material inlet 3, a screening mechanism 4 is installed inside the main body 1, the screening mechanism 4 comprises a support frame 401 fixedly connected to the inner wall of the main body 1, a screen 402 is fixedly connected inside the support frame 401, a first fixed seat 403 is fixedly connected to the bottom of the outer wall of the support frame 401, a spring 404 is fixedly connected to the bottom of the first fixed seat 403, a second fixed seat 405 is fixedly connected to the bottom of the spring 404, and the second fixed seat 406 is fixedly connected to the bottom of the spring 406. The bottom of the fixed seat 405 is fixedly connected to the inner wall of the main body 1. When in use, the sand to be screened is thrown in from the feed port 3, and the sand will fall onto the screen 402 inside the support frame 401. Since the gravity of the sand will compress the spring 404 between the first fixed seat 403 and the second fixed seat 405, some fine sand will first fall from the screen 402, and then the gravity will be reduced, and the spring 404 will start to rebound, shaking off the stacked sand, so that the screened sand is discharged from the first discharge pipe 6, thereby quickly completing the first step of sand screening;

[0024] like Figure 3 As shown, a driving mechanism 5 is installed inside the main body 1, and the driving mechanism 5 includes a first motor 501 fixedly connected to the top of the main body 1, and the output end of the first motor 501 is fixedly connected to a driving shaft 502, and the outer wall of the driving shaft 502 is fixedly connected to a plurality of stirring rods 503, and the driving shaft 502 runs through the main body 1. When in use, the first motor 501 on the top of the main body 1 is started to drive the driving shaft 502 to rotate, so that the plurality of stirring rods 503 start to rotate, so that the sand on the screen 402 can flow, and then can help the sand to be screened, and at the same time, the sand and gravel left after screening are stirred to flow into the converging port 8 through the sand and gravel channel 7, so that while accelerating the screening, the sand and gravel left after screening can be subjected to the next operation, which greatly improves the screening efficiency;

[0025] like Figure 4As shown, a first discharge pipe 6 is provided on one side of the outer wall of the main body 1, a sand and gravel channel 7 is provided on the inner wall of the main body 1, a convergence port 8 is fixedly connected to the inner wall of the main body 1, a crushing mechanism 9 is installed inside the main body 1, a second discharge pipe 10 is provided at the bottom of the main body 1, and the crushing mechanism 9 includes a second motor 901 fixedly connected to the front end of the main body 1, a first crushing roller 902 is fixedly connected to the output end of the second motor 901, a first gear 903 is fixedly connected to the outer wall of the rotating shaft on the first crushing roller 902, a second crushing roller 904 is rotatably connected to the inner wall of the main body 1, and a second gear 905 is fixedly connected to the outer wall of the rotating shaft on the second crushing roller 904. 903 is meshed with the second gear 905. When in use, the crushing mechanism 9 can crush the sand and gravel left after screening so that they can be reused to save resources. Specifically, when the sand and gravel flow down from the converging port 8, the second motor 901 at the front end of the starting body 1 will drive the first gear 903 and the first crushing roller 902 to rotate. Since the first gear 903 is meshed with the second gear 905, it will drive the second crushing roller 904 to rotate. When the sand and gravel pass between the first crushing roller 902 and the second crushing roller 904, they will be crushed into fine sand and then discharged from the second discharge pipe 10, so that they can be used in the construction again.

[0026] When the utility model is in use, the sand to be screened is thrown in from the feed port 3, and the sand will fall onto the screen 402 inside the support frame 401. Since the gravity of the sand will compress the spring 404 between the first fixing seat 403 and the second fixing seat 405, some fine sand will first fall from the screen 402, and then the gravity will be reduced, and the spring 404 will start to rebound, starting the first motor 501 on the top of the main body 1 to drive the drive shaft 502 to rotate, so that the multiple stirring rods 503 start to rotate, so that the sand on the screen 402 can flow. The movement can help the sand to be screened, and at the same time, the sand and gravel left after screening will flow into the converging port 8 through the sand and gravel channel 7 through stirring. When the sand and gravel flow down from the converging port 8, the second motor 901 at the front end of the starting body 1 will drive the first gear 903 and the first crushing roller 902 to rotate. Since the first gear 903 is meshed with the second gear 905, the second crushing roller 904 will be driven to rotate. When the sand and gravel pass between the first crushing roller 902 and the second crushing roller 904, they will be crushed into fine sand, thereby completing the entire sand screening process.
