Description

Technical Field

[0001] This utility model relates to the field of civil engineering equipment technology, specifically to a waste collection and screening device for civil engineering. Background Technology

[0002] Civil engineering encompasses the planning, construction, and maintenance of all infrastructure related to culture, soil, and water. It refers to the various technical work, including surveying, planning, design, and construction, for the construction, renovation, or expansion of various projects and related supporting facilities, excluding building construction. The construction of these projects requires a large amount of materials and generates a significant amount of waste. Many of these waste materials have high recycling value, thus requiring waste recycling devices for civil engineering construction to help workers improve recycling efficiency.

[0003] Application number CN202120261696.9 discloses a waste recycling device for civil engineering construction, including a waste recycling bin. A stable base is connected to the lower end of the waste recycling bin, and a cylinder is connected to the middle of the rear end of the bin. An inlet is connected to the upper end of the waste recycling bin. In this invention, waste is poured into the inlet and enters the upper screening basket. The cylinder drives two screening baskets and the waste bin to move back and forth simultaneously. Smaller waste passes through the upper filter screen and enters the lower screening basket, while even smaller waste passes through the lower filter screen and enters the waste bin. A handwheel drives an adjusting gear to rotate counterclockwise, which in turn moves the recycling door and locking head downwards, opening the recycling door. The cylinder pushes the two screening baskets and the waste bin out of the waste recycling bin. A slider and a first sliding rod allow the locking bar and locking head to move stably up and down, facilitating collection and storage by workers.

[0004] The aforementioned document discloses a waste recycling device for civil engineering construction, which has the following defects: During the use of this recycling device, two screening baskets and a waste bin are moved back and forth simultaneously by a cylinder, and the waste is screened and shaken into the waste bin. However, this structure can only screen two types of waste through the screening baskets. When the waste in the waste is of different sizes, the price will also be different. The device cannot screen the waste more efficiently. At this time, it may be wasteful to process waste of different prices together.

[0005] Therefore, it can be seen that the existing waste recycling equipment for civil engineering construction does not have the function of screening different types of waste. It is necessary to improve the existing equipment to provide a function that can screen different types of waste. Utility Model Content

[0006] The purpose of this invention is to provide a waste collection and screening device for civil engineering, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a waste collection and screening device for civil engineering, including a vibrating structure and a screening structure. The screening structure is installed in the middle of the vibrating structure. The screening structure includes an upper screen layer, a lower screen layer and a bottom layer, which are arranged from top to bottom. Screen mesh layers are respectively provided on the inner walls of the upper screen layer and the lower screen layer. Two smoothing rods are provided on the inner walls of the top two sides of the upper screen layer and the lower screen layer. A side hopper and a side hopper are respectively installed on one side of the upper screen layer and the lower screen layer. The purpose of this setup is that, during the operation of the screening device, waste material is poured into the feeding hopper and slides down the inclined inner wall of the hopper. It then falls from the bottom layer to the upper screen layer. A vibrating motor drives the bottom layer to vibrate, and the swing arms on both sides cause the screening structure to sway back and forth. The upper screen layer sways back and forth, leveling the waste material. The leveling rods on both sides further level the waste material. Smaller pieces of waste material are screened by the screen layer and fall into the lower screen layer during the swaying process. The leveling rods limit the forward-flowing waste material's backward path. Finally, the largest pieces of waste material pass through the side hopper. As the waste falls downwards, it is smoothed out by the back-and-forth swinging and the pushing force of the smoothing rod. Finally, the medium-sized waste surges forward and is discharged through the side hopper. When the waste shakes in the lower screen layer, the smallest waste is screened through the bottom screen layer and falls into the bottom layer. Finally, the waste in the bottom layer is discharged through the middle and lower hopper by the back-and-forth swinging. Because the drop troughs of the side hopper, the side hopper and the middle and lower hopper are located in different positions, the three sizes of waste can be collected at the same time. The design of this screening structure can screen the waste into three categories at the same time, which greatly improves the waste collection efficiency.

[0009] Furthermore, fixed frames are fixed to the outer walls of both ends of the upper screen layer, lower screen layer, and bottom layer, and a middle and lower hopper is installed on one side of the bottom layer. The purpose of this arrangement is that during the use of this screening device, the smallest waste material is screened through the bottom screen layer and falls into the bottom layer, and finally the waste material in the bottom layer is discharged from the middle and lower hopper by swinging back and forth.

[0010] Furthermore, the vibrating structure includes a base frame, with side frames on both sides of the top of the base frame, and a swing arm installed on the side of the two side frames that are close to each other. The purpose of this arrangement is that during the use of the screening device, the bottom layer is driven to vibrate by the vibrating motor, and the screening structure is swayed back and forth by the swing arms on both sides.

[0011] Furthermore, the other end of the swing arm is respectively installed on the outer walls of the lower screen layer and the bottom layer. The purpose of this arrangement is that during the use of this screening device, the upper screen layer shakes back and forth to level the waste material, and smaller waste materials are screened by the screen layer and fall into the lower screen layer during the shaking process.

[0012] Furthermore, a feeding hopper is provided on the outer wall of the top side of the base frame away from the side hopper, and the feeding hopper is located above the upper screen layer. The purpose of this arrangement is that during the use of this screening device, waste material is poured in from the feeding hopper, slides down the inner wall of the inclined surface around the feeding hopper, and falls down through the bottom layer to the upper screen layer.

[0013] Furthermore, a vibration motor is installed on the bottom outer wall of the base frame. The purpose of this arrangement is that, during the use of the screening device, the vibration motor drives the bottom layer to vibrate, and the swing arms on both sides cause the screening structure to swing back and forth.

[0014] This utility model has the following beneficial effects:

[0015] (1) By setting up a screen layer and upper and lower screen layers, the smaller waste material is screened by the screen layer and falls into the lower screen layer during the shaking process. The largest waste material falls down through the side lower bucket, the medium-sized waste material surges forward and is discharged through the side bucket, and the smallest waste material is discharged through the middle lower bucket by swinging back and forth. Since the drop troughs of the side lower bucket, the side bucket and the middle lower bucket are located in different positions, the three sizes of waste material can be collected at the same time.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1 - Figure 4As shown, this utility model is a waste collection and screening device for civil engineering, including a vibrating structure 1 and a screening structure 2. The screening structure 2 is installed in the middle of the vibrating structure 1. The screening structure 2 includes an upper screen layer 202, a lower screen layer 203 and a bottom layer 204. The upper screen layer 202, the lower screen layer 203 and the bottom layer 204 are arranged sequentially from top to bottom. Screen mesh layers 209 are respectively provided on the inner walls of the upper screen layer 202 and the lower screen layer 203. Two smoothing rods 208 are provided on the inner walls of the top two sides of the upper screen layer 202 and the lower screen layer 203. A side bucket 205 and a side bucket 206 are respectively installed on one side of the upper screen layer 202 and the lower screen layer 203. The purpose of this setup is that, during the operation of the screening device, waste material is poured into the feeding hopper 104. The waste material slides down the inclined inner wall of the feeding hopper 104, falls through the bottom layer 204 to the upper screen layer 202, and is driven by the vibration motor 105 to vibrate the bottom layer 204. The two swing arms 103 cause the screening structure 2 to swing back and forth. The upper screen layer 202 swings back and forth, leveling the waste material. The two leveling rods 208 level the waste material. Smaller waste materials are screened by the screen layer 209 and fall into the lower screen layer 203 during the shaking process. The leveling rods 208 limit the forward-flowing waste material to a backward path. Finally, the largest waste material passes through the side hopper. 205 falls downwards, and the waste falling into the lower screen layer 203 is smoothed by the back-and-forth swing and the pushing force of the smoothing rod 208. Finally, the medium-sized waste surges forward and is discharged through the side hopper 206. When the waste shakes in the lower screen layer 203, the smallest waste is screened through the bottom screen layer 209 and falls into the bottom layer 204. Finally, the waste in the bottom layer 204 is discharged through the middle and lower hopper 207 by the back-and-forth swing. Since the drop troughs of the side lower hopper 205, the side hopper 206 and the middle and lower hopper 207 are in different positions, the three sizes of waste can be collected at the same time. The design of this screening structure 2 can screen the waste into three types at the same time, which greatly improves the waste collection efficiency.

[0026] Fixed frames 201 are fixed to the outer walls of the upper screen layer 202, lower screen layer 203, and bottom layer 204 at both ends. A middle and lower hopper 207 is installed on one side of the bottom layer 204. The purpose of this arrangement is that during the use of this screening device, the smallest waste material is screened through the bottom screen layer 209 and falls into the bottom layer 204. Finally, the waste material in the bottom layer 204 is discharged from the middle and lower hopper 207 by swinging back and forth.

[0027] The vibrating structure 1 includes a base frame 101, with side frames 102 on both sides of the top of the base frame 101. A swing arm 103 is installed on the side of the two side frames 102 that are close to each other. The purpose of this arrangement is that during the use of the screening device, the bottom layer 204 is driven to vibrate by the vibrating motor 105, and the screening structure 2 is swayed back and forth by the swing arms 103 on both sides.

[0028] The other end of the swing arm 103 is installed on the outer walls of the lower screen layer 203 and the bottom layer 204 on both sides. The purpose of this arrangement is that during the use of the screening device, the upper screen layer 202 swings back and forth to flatten the waste material, and smaller waste materials are screened by the screen layer 209 and fall into the lower screen layer 203 during the swinging process.

[0029] A feeding hopper 104 is provided on the outer wall of the top side of the base frame 101 away from the side hopper 206, and the feeding hopper 104 is located above the upper screen layer 202. The purpose of this arrangement is that during the use of this screening device, waste material is poured in from the feeding hopper 104, slides down the inner wall of the inclined surface around the feeding hopper 104, and falls down through the bottom layer 204 to the upper screen layer 202.

[0030] A vibrating motor 105 is installed on the bottom outer wall of the base frame 101. The purpose of this arrangement is that during the use of the screening device, the vibrating motor 105 drives the bottom layer 204 to vibrate, and the two swing arms 103 on both sides cause the screening structure 2 to swing back and forth.

[0031] During use, waste material is poured into the feeding hopper 104. The waste material slides down the inclined inner wall of the feeding hopper 104, falls through the bottom layer 204 to the upper screen layer 202, and is driven by the vibration motor 105 to vibrate the bottom layer 204. The two swing arms 103 cause the screening structure 2 to swing back and forth. The upper screen layer 202 swings back and forth, leveling the waste material. The two leveling rods 208 level the waste material. Smaller waste materials are screened by the screen layer 209 and fall into the lower screen layer 203 during the shaking process. The leveling rods 208 limit the forward-flowing waste material to a backward path. Finally, the largest waste material passes through the side hopper 20. 5. The waste falling into the lower screen layer 203 is smoothed by the back-and-forth swing and the pushing force of the smoothing rod 208. Finally, the medium-sized waste surges forward and is discharged through the side hopper 206. When the waste shakes in the lower screen layer 203, the smallest waste is screened through the bottom screen layer 209 and falls into the bottom layer 204. Finally, the waste in the bottom layer 204 is discharged through the middle and lower hopper 207 by the back-and-forth swing. Since the drop troughs of the side lower hopper 205, side hopper 206 and middle and lower hopper 207 are in different positions, the three sizes of waste can be collected at the same time. The design of this screening structure 2 can screen the waste into three types at the same time, which greatly improves the waste collection efficiency.
