Description

Technical Field

[0001] This utility model relates to the technical field of raw material screening device for construction of basement structure cracking in riverside areas, and in particular to a raw material screening device for construction of basement structure cracking in riverside areas. Background Technology

[0002] Uneven settlement caused by factors such as fluctuations can lead to cracks in the basement roof or floor slab. Basement structural cracks are usually repaired with concrete. To improve the quality of the concrete, the raw materials need to be screened, such as larger particles in sand and gravel. This will result in better quality concrete that is less prone to cracking.

[0003] Chinese patent CN218359678U discloses a screening device for anti-cracking construction of basement surface concrete, including a machine body. The top of the machine body has a second feed port. The machine body has an installation plate inside, with both sides of the installation plate extending out of the machine body. A fixing block is fixedly installed on one side of the top of the machine body, and a first spring is fixedly installed on one side of the fixing block. One end of the first spring is fixedly connected to the machine body. The installation plate has an opening inside, and a filter screen is installed inside the opening. Insert blocks are fixedly installed on both sides of the filter screen and are inserted into the interior of the installation plate.

[0004] The aforementioned screening device, while employing a mechanism where rotating the limiting block stretches the spring, causing the limiting block to engage with the slot and allowing the filter screen to be installed, and vice versa, allows for filter screen removal based on the required aperture size to accommodate different concrete particle sizes, suffers from several drawbacks. Large concrete particles remaining on the filter screen during screening require manual removal, which is cumbersome and inefficient. Furthermore, the flat, unobstructed design of the filter screen allows concrete material to easily fall off, resulting in incomplete screening. Therefore, improvements are urgently needed. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a material screening device for cracking construction of basement structures in riverside areas, which is highly practical, easy to operate, and has a simple structure. It solves the problems mentioned in the background art, such as the need to manually remove large particles of concrete material left on the filter screen during screening, which is cumbersome and inefficient. Moreover, during screening, because the filter screen is a planar structure with no obstructions on both sides, concrete material can easily fall off the sides of the filter screen, resulting in incomplete screening. Therefore, there is an urgent need to improve this device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material screening device for construction of basement structures cracking in riverside areas, comprising a device body and a screen plate. The screen plate is disposed inside the device body, and a screen mesh is installed at the center of the screen plate. Discharge inclined surfaces are provided on both sides of the screen plate surface, and side baffles are fixed on both sides of the screen plate. A housing is fixed on both inner walls of the device body below the screen plate, and a fourth rotary drive component is installed inside the housing. A cam is installed at the output end of the fourth rotary drive component, and the cam cooperates with the screen plate. The inner wall of the device body above the screen plate... A feeding track is fixed, and a lead screw is installed inside the feeding track. A slider is threaded onto the outer wall of the lead screw. One end of the slider extends above the screen plate and is fixed to a feeding plate. A third rotary drive is installed at one end of the feeding track. The output end of the third rotary drive is fixedly connected to the lead screw. A first receiving box is provided inside the main body of the device below the screen plate. A second receiving box is provided on both sides of the main body of the device. A conveying cylinder is fixed at the top of the main body of the device. One end of the conveying cylinder is connected to the main body of the device through a guide pipe. A storage bucket is fixed on one side of the top of the conveying cylinder. The storage bucket is connected to the conveying cylinder through a discharge pipe.

[0007] As a further embodiment of this utility model, both sides of the sieve plate are connected to the main body of the device through spring members to provide elasticity to the sieve plate.

[0008] As a further embodiment of this utility model, a second rotary drive component is installed on the top of the main body of the device above the hopper, and a crushing paddle is installed at the output end of the second rotary drive component. The bottom end of the crushing paddle extends into the interior of the hopper to facilitate the breaking up of raw materials.

[0009] As a further embodiment of this utility model, both ends of the sieve plate penetrate the main body of the device and extend to the top of the second receiving box, which facilitates the introduction of large-particle raw materials into the second receiving box.

[0010] As a further embodiment of this utility model, a conveying auger is installed inside the conveying cylinder, and a first rotary drive is installed at one end of the conveying cylinder. The output end of the first rotary drive is fixedly connected to the conveying auger, which facilitates the conveying of raw materials.

[0011] As a further embodiment of this utility model, a conveying auger is installed inside the conveying cylinder, and a first rotary drive is installed at one end of the conveying cylinder. The output end of the first rotary drive is fixedly connected to the conveying auger, which facilitates the conveying of raw materials.

[0012] As a further embodiment of this invention, the plane at the bottom of the pusher plate is higher than the plane at the top of the screen to prevent unscreened small particles of raw material from being pushed away.

[0013] This utility model provides a raw material screening device for construction work on cracked basement structures in riverside areas, which has the following beneficial effects:

[0014] Raw materials fall onto the screen inside the sieve plate. The fourth rotary drive inside the machine housing drives the cam to rotate. The cam continuously pushes the sieve plate, causing it to vibrate under the action of the spring. This allows small particles of raw material to pass through the mesh of the sieve and fall into the first collection box, while large particles remain on the sieve. Vibration screening results in high screening efficiency. During vibration screening, the side baffles prevent raw materials from falling from both sides of the sieve plate. Furthermore, during the screening process, the third rotary drive drives the lead screw to rotate in both directions, causing the slider to move the pusher plate left and right along the pusher track. The pusher plate pushes the large particles of raw material on the sieve to the discharge slope, where they roll into the second collection box. The first and second collection boxes can collect large and small particles of raw material separately. This design optimizes the internal structure of the device, not only realizing automatic screening and collection without manual material handling, but also preventing raw materials from falling from both sides of the sieve plate, resulting in more comprehensive screening.

A cam 14 is installed at the output end of the fourth rotary drive component 13, and the cam 14 cooperates with the screen plate 4. A pusher rail 11 is fixed on the inner wall of the device body 1 above the screen plate 4. Inside the channel 11, a lead screw 1101 is installed, and a slider 1102 is threadedly connected to the outer wall of the lead screw 1101. One end of the slider 1102 extends to the top of the screen plate 4 and is fixed with a pusher plate 1103. One end of the pusher track 11 is equipped with a third rotary drive 1104. The output end of the third rotary drive 1104 is fixedly connected to the lead screw 1101. Inside the device body 1 below the screen plate 4, a first receiving box 2 is provided. On both sides of the device body 1, a second receiving box 3 is provided. A conveying cylinder 6 is fixed at the top of the device body 1, and one end of the conveying cylinder 6 is connected to the device body 1 through a guide pipe 603. A storage bucket 7 is fixed on one side of the top of the conveying cylinder 6, and the storage bucket 7 is connected to the conveying cylinder 6 through a discharge pipe 701.

[0022] Both sides of the sieve plate 4 are connected to the main body 1 of the device through spring members 5, which provide elasticity to the sieve plate 4;

[0023] A second rotary drive component 9 is installed on the top of the main body 1 above the collection hopper 8, and a crushing paddle 10 is installed at the output end of the second rotary drive component 9. The bottom end of the crushing paddle 10 extends into the interior of the collection hopper 8 to facilitate the breaking up of raw materials.

[0024] Both ends of the sieve plate 4 pass through the main body 1 of the device and extend to the top of the second receiving box 3, which facilitates the introduction of large-particle raw materials into the second receiving box 3.

[0025] The material conveying cylinder 6 is equipped with a material conveying auger 601 inside, and a first rotary drive 602 is installed at one end of the material conveying cylinder 6. The output end of the first rotary drive 602 is fixedly connected to the material conveying auger 601 to facilitate the conveying of raw materials.

[0026] The material conveying cylinder 6 is equipped with a material conveying auger 601 inside, and a first rotary drive 602 is installed at one end of the material conveying cylinder 6.
