Description

Technical Field

[0001] This utility model relates to the field of sand and gravel aggregate processing technology, specifically to a vibration-type sand and gravel aggregate screening device. Background Technology

[0002] Sand and gravel aggregates are a general term for materials such as sand, pebbles (gravel), crushed stone, boulders, and quarries. They are mainly used in the construction of concrete and masonry structures, and are divided into coarse aggregates and fine aggregates.

[0003] Traditional sand and gravel aggregate screening equipment generally suffers from the following problems: severe dust pollution (open screening operations lead to the release of ultrafine dust such as PM2.5 / PM10, which violates environmental protection regulations such as the "Air Pollution Prevention and Control Law" and endangers the respiratory health of operators), insufficient grading accuracy (single-layer screen structure can only separate aggregates of a single particle size, which cannot meet the needs of simultaneous production of multi-grade aggregates in construction projects), high resource waste rate (screening residues are directly discarded, lacking a secondary material recycling mechanism, resulting in aggregate loss), and high maintenance costs (traditional vibrating screen mechanisms are prone to clogging and difficult to clean, requiring frequent shutdowns for manual cleaning, reducing the continuous operation capacity of the equipment). Utility Model Content

[0004] The purpose of this utility model is to provide a vibration-type sand and gravel aggregate screening equipment. This screening equipment can effectively reduce dust pollution, and by adopting a multi-stage screen, it can effectively ensure the grading accuracy, while ensuring the full utilization of resources and effectively reducing maintenance costs.

[0007] Preferably, the top of the base is further provided with a stabilizing and limiting component. The stabilizing and limiting component includes a support rod fixedly connected to the top of the circular base plate. A connecting ring is fixedly connected to the top of the support rod. A displacement plate is slidably connected to the inner side wall of the connecting ring. A first connecting block is fixedly connected to one end of the displacement plate.

The bottom of the screw is rotatably connected to the top of the other end of the displacement block.

[0008] Preferably, the bottom of the base is fixedly connected with four support pads of equal size, which are equidistantly fixed at the four corners of the bottom of the base.

[0009] Preferably, a control panel is fixedly connected to the surface of the base, and an on / off button is fixedly connected to the surface of the control panel.

[0011] Preferably, the bottom of the screening frame is provided with four positioning posts, which are arranged in a circular array along the central axis of the screening frame to facilitate the stacking of screening frames layer by layer.

[0012] The present invention has the following beneficial effects:

[0013] 1. This utility model equipment, by setting up a vibrating screening component, performs vibrating screening of sand and gravel aggregates during the screening process. In order to achieve uniform screening of sand and gravel aggregates, the sand and gravel aggregates need to be vibrated. At this time, the operator turns on the double-head motor to make the output shaft rotate. During the rotation of the output shaft, the cam will rotate. During the rotation of the cam, the top part of the cam will squeeze the bottom of the rectangular support plate. Under the limiting action of the limiting sleeve and the limiting column, the outer wall of the rectangular support plate will be made to move upward. Under the action of the first spring, the rectangular support plate will vibrate up and down, thereby achieving the purpose of vibrating screening of sand and gravel aggregates and improving the screening effect of sand and gravel aggregates.

[0014] 2. This utility model equipment, by setting a stable limiting component, allows the operator to push the displacement plate after assembling multiple screening frames. This causes the displacement plate to move laterally along the outer wall of the support rod, positioning the displacement block above the top cover. Subsequently, by rotating the adjusting block, the screw is rotated. During the rotation of the screw, the displacement block moves downward. Under the limiting effect of the second spring and the extension rod, the displacement block descends to the top of the top cover, thereby limiting the top of the top cover and achieving the purpose of pressing the screening frames, thus improving the stability of the screening frames during vibration.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] A preferred embodiment of the impact-type sand and gravel aggregate screening equipment provided by this utility model is, for example... Figures 1 to 6 As shown: A vibratory sand and gravel aggregate screening device includes a base 1 and a vibrating screening assembly 51 disposed on the top of the base 1. The vibrating screening assembly 51 includes a support frame 511 fixedly connected to the inner wall of the base 1. A double-head motor 512 is fixedly connected to the top inner wall of the support frame 511. An output shaft 513 is fixedly connected to the output end of the double-head motor 512. A cam 514 is fixedly connected to the outer wall of the other end of the output shaft 513. A rectangular bearing plate 515 is slidably connected to the top of the cam 514. Limiting sleeves 516 are fixedly connected to the four corners of the outer wall of the rectangular bearing plate 515. Limiting posts 517 are slidably connected to the inner wall of the other side of the limiting sleeves 516. The bottom of the limiting posts 517 is fixedly connected to the top of the base 1. A first spring 518 is fixedly connected to the bottom of the limiting sleeves 516. The other end of the first spring 518 is fixedly connected to the top of the base 1.

[0025] By setting up the vibrating screen assembly 51, in order to achieve uniform screening of sand and gravel aggregates, it is necessary to vibrate the sand and gravel aggregates during the screening process. At this time, the operator turns on the dual-head motor 512 to make the output shaft 513 rotate. During the rotation of the output shaft 513, the cam 514 will rotate. During the rotation of the cam 514, its top part will squeeze the bottom of the rectangular support plate 515. Under the limiting action of the limiting sleeve 516 and the limiting column 517, the outer wall of the rectangular support plate 515 will be limited, which will cause the rectangular support plate 515 to move upward. Under the action of the first spring 518, the rectangular support plate 515 will vibrate up and down, thereby achieving the purpose of vibrating screening of sand and gravel aggregates and improving the screening effect of sand and gravel aggregates.

[0026] Furthermore, the vibrating screening assembly 51 also includes a circular base plate 519 fixedly connected to the top center of the rectangular support plate 515. A collection frame 5110 is slidably connected to the inner top wall of the circular base plate 519. A fixing ring 5111 is fixedly connected to the outer top wall of the collection frame 5110. A positioning column 5112 is slidably connected to the inner top wall of the collection frame 5110. A screening frame 5113 is fixedly connected to the other end of the positioning column 5112. An embedded column 5114 is slidably connected to the inner top wall of the screening frame 5113. A top cover 5115 is fixedly connected to the other end of the embedded column 5114.

[0027] Before screening the sand and gravel aggregate, the operator puts the sand and gravel aggregate into the screening frame 5113. Then, the embedded column 5114 at the bottom of the top cover 5115 is inserted into the top inner wall of the screening frame 5113, and multiple screening frames 5113 are sequentially installed above the aggregate frame 5110. During the vibration of the circular bottom plate 519, multiple screening frames 5113 will be driven to vibrate, realizing the vibration screening of the sand and gravel aggregate. Through the multi-stage screening frames 5113, the sand and gravel aggregate can be graded and screened, effectively separating impurities from the sand and gravel aggregate.

[0028] A preferred embodiment of the impact-type sand and gravel aggregate screening equipment provided by this utility model is, for example... Figures 1 to 6As shown: A stabilizing and limiting component 52 is also provided on the top of the base 1. The stabilizing and limiting component 52 includes a support rod 521 fixedly connected to the top of the circular base plate 519. A connecting ring 522 is fixedly connected to the top of the support rod 521. A displacement plate 523 is slidably connected to the inner wall of the side of the connecting ring 522. A first connecting block 524 is fixedly connected to one end of the displacement plate 523. A sleeve 525 is fixedly connected to the bottom of the first connecting block 524. A second spring 526 is fixedly connected to the top of the inner wall of the sleeve 525. An extension rod 527 is fixedly connected to the other end of the spring 526. A second connecting block 528 is fixedly connected to the bottom of the extension rod 527. A displacement block 529 is fixedly connected to the side wall of the second connecting block 528. The inner wall of one end of the displacement block 529 is slidably connected to the outer wall of the support rod 521. A screw 5210 is threadedly connected to the inner wall of the other end of the displacement plate 523. An adjusting block 5211 is fixedly connected to the top outer wall of the screw 5210. The bottom of the screw 5210 is rotatably connected to the top of the other end of the displacement block 529.

[0029] By setting a stabilizing limiting component 52, after assembling multiple screening frames 5113, the operator pushes the displacement plate 523, causing the displacement plate 523 to move the displacement block 529 laterally along the outer wall of the support rod 521, so that the displacement block 529 is above the top cover 5115. Then, by rotating the adjusting block 5211, the screw 5210 is rotated. During the rotation of the screw 5210, the displacement block 529 is moved downward. Under the limiting action of the second spring 526 and the extension rod 527, the displacement block 529 is lowered to the top of the top cover 5115, thereby limiting the top of the top cover 5115 and thus achieving the purpose of pressing the screening frame 5113, improving the stability of the screening frame 5113 during vibration.

[0030] Furthermore, a support pad 2 is fixedly connected to the bottom of the base 1. There are four support pads 2, all of the same size, and they are fixedly connected at equal intervals at the four corners of the bottom of the base 1. By setting four support pads 2 at the bottom of the base 1, a stable support function for the base 1 can be achieved.

[0031] Furthermore, a control panel 3 is fixedly connected to the surface of the base 1, and an on / off button 4 is fixedly connected to the surface of the control panel 3.

[0032] Furthermore, there are eight screening frames 5113, all of equal size, and the screening troughs inside the eight screening frames 5113 are arranged from large to small from top to bottom. By arranging the screening troughs inside the eight screening frames 5113 from large to small from top to bottom, the sand and gravel aggregates can be graded and screened, making the screening process of the sand and gravel aggregates more uniform.

[0033] In addition, the bottom of the screening frame 5113 is provided with four positioning posts 5112, which are arranged in a circular array along the central axis of the screening frame 5113 to facilitate the layering of the screening frames 5113.

[0034] The working process and principle of this utility model:

[0035] In the process of screening sand and gravel aggregates, in order to achieve uniform screening, the sand and gravel aggregates need to be vibrated. At this time, the operator turns on the double-head motor 512 to make the output shaft 513 rotate. During the rotation of the output shaft 513, the cam 514 will rotate. During the rotation of the cam 514, its top part will squeeze the bottom of the rectangular support plate 515. Under the limiting action of the limiting sleeve 516 and the limiting column 517, the outer wall of the rectangular support plate 515 will be moved upward, and under the action of the first spring 518, the rectangular support plate 515 will vibrate up and down, thereby achieving the purpose of vibrating screening of sand and gravel aggregates and improving the screening effect of sand and gravel aggregates.

[0036] Before screening the sand and gravel aggregate, the operator puts the sand and gravel aggregate into the screening frame 5113. Then, the embedded column 5114 at the bottom of the top cover 5115 is inserted into the top inner wall of the screening frame 5113. Multiple screening frames 5113 are then sequentially installed above the aggregate frame 5110. During the vibration of the circular bottom plate 519, multiple screening frames 5113 will be driven to vibrate, thereby achieving vibration screening of the sand and gravel aggregate. Through the multi-stage screening frames 5113, the sand and gravel aggregate can be graded and screened, effectively separating impurities from the sand and gravel aggregate.

[0037] After assembling multiple screening frames 5113, the operator pushes the displacement plate 523, causing the displacement block 529 to move laterally along the outer wall of the support rod 521, positioning the displacement block 529 above the top cover 5115. Then, by rotating the adjusting block 5211, the screw 5210 is rotated. During the rotation of the screw 5210, the displacement block 529 moves downward. Under the limiting action of the second spring 526 and the extension rod 527, the displacement block 529 descends to the top of the top cover 5115, thereby limiting the top of the top cover 5115 and thus achieving the purpose of pressing the screening frame 5113, improving the stability of the screening frame 5113 during vibration.
