Detailed Implementation

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1This utility model provides a rapid sand and gravel filtration device for construction engineering, including a working chamber 1. The top of the working chamber 1 is provided with a feed inlet 2 for pouring sand and gravel, and the bottom middle is provided with a discharge outlet 3 for discharging sand and gravel. It also includes a filter mechanism 4 located at the bottom of the feed inlet 2. The bottom of the filter mechanism 4 is provided with no less than two sets of screens 5. The screens 5 are all inclined, and the inclination directions of adjacent sets of screens 5 are opposite, which is conducive to screening sand and gravel. The working chamber 1 is provided with discharge outlets 6 on both sides corresponding to the screens 5. The number of discharge outlets 6 is opposite to that of the screens 5, and they are located at the inclined end of the screens 5 to facilitate the discharge of sand and gravel. The inner side of each discharge outlet 6 is provided with a dustproof curtain to prevent dust from being generated when the sand and gravel are moved and screened, thus avoiding pollution of the surrounding environment.

[0021] Please see Figure 1-2 This utility model provides a rapid sand and gravel filtration device for construction engineering. The filtration mechanism 4 includes a motor 41, side plates 42, slide grooves 43, sliders 44, connecting plates 45, connecting panels 46, a screen 47, and a transmission mechanism 48. A set of motors 41 is provided at the top of each of the two sides of the working chamber 1. A set of side plates 42 is provided inside the working chamber 1 corresponding to the positions of the two sets of motors 41. A slide groove 43 is provided in the middle of each side plate 42, and a set of sliders 44 is slidably connected within each slide groove 43. The middle of the side of each set of sliders 44 away from the side plate 42 is... A set of rotating shafts are connected to the middle of the connecting plate 45. The connecting plate 45 can rotate around the rotating shafts. Both ends of the opposite sides of the two sets of connecting plates 45 are connected to the left and right ends of the screen 47 through a set of connecting panels 46. The area of ​​the screen 47 can completely cover the bottom area of ​​the feed inlet 2, ensuring that the sand and gravel poured from the feed inlet 2 can fall onto the screen 47. The movement of the connecting plate 45 can drive the screen 47 to swing, thereby improving the filtration and screening efficiency of the sand and gravel on it. The front and rear ends of the side plate 42 are connected to the connecting plate 45 through the transmission mechanism 48.

[0022] Please see Figure 2-3 This utility model provides a rapid sand and gravel filtration device for construction engineering. The components of the transmission mechanism 48 are all the same. The transmission mechanism 48 includes a connecting shaft 481, a first transmission arm 482 and a second transmission arm 483. The front and rear ends of the opposite side plates 42 are connected to a set of first transmission arms 482 through the connecting shaft 481. The outer ends of the two sets of connecting shafts 481 at the front end extend through to the outside of the working chamber 1 and are connected to the drive shaft of the motor 41. The rotation of the drive shaft of the motor 41 can drive the two sets of connecting shafts 481 and the two sets of first transmission arms 482 at the front end to rotate. The other ends of the two sets of first transmission arms 482 at the front end are connected to the front end of the connecting plate 45 and can drive it to move. The other ends of the two sets of first transmission arms 482 at the rear end are provided with a set of second transmission arms 483 and are connected to the rear end of the connecting plate 45 through the second transmission arms 483. This can restrict the movement path of the connecting plate 45 so that it can only drive the screen 47 to swing back and forth.

[0023] The working principle is as follows:

[0024] In use, sand and gravel can be poured into the working chamber 1 from the feed inlet 2 and fall onto the screen 47. Then, the machine is started. Two sets of motors 41 drive the shaft to rotate, which can drive the connecting plate 45 to move through the two sets of connecting shafts 481 at the front end and the two sets of transmission arms 482 at the front end. Under the constraint of the two sets of transmission arms 482 and transmission arm 483 at the rear end, the screen 47 swings back and forth to filter and screen the sand and gravel. The screened sand and gravel can fall into the screen 5 at the bottom in sequence. After screening, they are discharged through the discharge outlet 6 and discharge outlet 3 respectively, realizing the rapid screening and filtration of sand and gravel.

[0025] The above description is merely 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.
