Technical Field
[0001] The utility model relates to the technical field of aggregate sorting in road and bridge construction, and more specifically, to an aggregate sorting device for road and bridge construction. Background Art
[0002] Aggregates in road and bridge construction refer to granular substances used in pavement materials such as concrete and asphalt. Their main functions are to provide strength, stability, and durability. Aggregates usually include sand, gravel, and crushed stone, etc. Their quality and characteristics directly affect the construction quality and the service life of the project.
[0003] The importance of sorting aggregates lies in that different specifications and types of aggregates can meet the requirements of concrete mix ratios, thereby ensuring the performance of the overall structure. For example, oversized or undersized aggregates may lead to problems such as insufficient compaction, reduced strength, or cracking of concrete. Through reasonable sorting, the construction efficiency and quality can be improved, and the cost of later maintenance can be reduced.
[0004] When sorting aggregates, the screening devices in the prior art mostly use sieve plates to screen the aggregates. However, in this process, the aggregates directly fall on the sieve plates and are difficult to evenly cover the sieve plates, which easily leads to the accumulation of aggregates on the sieve plates, thereby affecting the sorting effect and efficiency of the aggregates. Summary of the Utility Model
[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide an aggregate sorting device for road and bridge construction to solve the problem that when sorting aggregates, the screening devices in the prior art mostly use sieve plates to screen the aggregates, but in this process, the aggregates directly fall on the sieve plates and are difficult to evenly cover the sieve plates, which easily leads to the accumulation of aggregates on the sieve plates, thereby affecting the sorting effect and efficiency of the aggregates.
[0006] To solve the above technical problems, the utility model provides the following technical solution: An aggregate sorting device for road and bridge construction, including a frame. A sorting bin is fixedly connected to the top of the frame. The sorting bin is inclined, and a sieve plate is fixedly connected to the inside of the sorting bin. An inlet bin and a pair of discharge bins are respectively arranged at both ends of the sorting bin. The sieve plate divides the sorting bin into two parts. The discharge bins are respectively internally communicated with the two parts of the sorting bin divided by the sieve plate. A linkage plate is arranged inside the sorting bin. A plurality of push plates are arranged at the bottom of the linkage plate. Both ends of the push plate extend obliquely to both sides to form a triangular structure. A motor is fixedly connected to the outer wall of the sorting bin. A transmission mechanism for providing power for the reciprocating movement of the linkage plate is arranged inside the sorting bin.
[0007] The transmission mechanism includes a plurality of limiting rings symmetrically and fixedly connected to the inner wall of the sorting bin, and limiting grooves are formed on the opposite sides between the limiting rings. A plurality of connecting rods are fixedly connected to the outer wall of the linkage plate, and the other ends of the connecting rods respectively extend into the limiting grooves. The main shaft of the motor penetrates through the outer wall of the sorting bin to its interior and is fixedly connected to a transmission rod. A sliding groove is formed on the outer wall of the transmission rod, and a sliding block is slidably connected to the inner wall of the sliding groove. The other side of the sliding block is rotatably connected to a clamping block, and the other side of the clamping block is fixedly connected to the outer wall of the linkage plate.
[0008] Preferably, the push plates in the same column are taken as a group, and two adjacent groups of push plates are arranged staggeredly.
[0009] Preferably, rollers are rotatably connected to the ends of the connecting rods extending into the limiting grooves, and the rollers are in contact with the inner wall of the limiting grooves.

Subsequently, the aggregate will enter the sorting bin along the feed bin and be sorted by the sieve plate. During this process, the transmission mechanism makes the linkage plate move cyclically. The cyclic movement of the linkage plate makes the triangular push plate reciprocally push and guide the aggregate, so that the aggregate is evenly distributed on the sieve plate, thereby increasing the sorting and screening effect and efficiency of the sieve plate on the aggregate. After sorting, the aggregate will respectively enter the discharge bin, thus completing the sorting of the aggregate.
[0014] 2. In the present utility model, the push plate not only has a triangular structure and can push the aggregate, but also the push plates in the same column are taken as a group, and two adjacent groups of push plates are arranged staggeredly.

[0021] As Figures 1 to 4 shown, the present utility model relates to: an aggregate sorting device for road and bridge construction, including a frame 1. A sorting bin 2 is fixedly connected to the top of the frame 1. The sorting bin 2 is inclined, and a sieve plate 3 is fixedly connected to the inside of the sorting bin 2. An inlet bin 4 and a pair of discharge bins 5 are respectively arranged at both ends of the sorting bin 2. The sieve plate 3 divides the sorting bin 2 into two parts. The discharge bins 5 are respectively communicated with the two internal parts of the sorting bin 2 divided by the sieve plate 3. A linking plate 6 is arranged inside the sorting bin 2. A plurality of push plates 7 are arranged at the bottom of the linking plate 6. Both ends of the push plate 7 extend obliquely to both sides to form a triangular structure. A motor 8 is fixedly connected to the outer wall of the sorting bin 2. A transmission mechanism for providing power for the reciprocating movement of the linking plate 6 is arranged inside the sorting bin 2;
[0022] The transmission mechanism includes a plurality of limit rings 9 symmetrically and fixedly connected to the inner wall of the sorting bin 2. Limit grooves 10 are opened on the opposite surfaces between the limit rings 9. A plurality of connecting rods 11 are fixedly connected to the outer wall of the linking plate 6. The other ends of the connecting rods 11 respectively extend into the limit grooves 10. The main shaft of the motor 8 penetrates through the outer wall of the sorting bin 2 to its inside and is fixedly connected to a transmission rod 12. A slide groove 13 is opened on the outer wall of the transmission rod 12. A slide block 14 is slidably connected to the inner wall of the slide groove 13. The other side of the slide block 14 is rotatably connected to a clamping block 15. The other side of the clamping block 15 is fixedly connected to the outer wall of the linking plate 6;
[0023] Specifically, the aggregate to be screened is placed into the feed bin 4. Subsequently, the aggregate will enter the sorting bin 2 along the feed bin 4, and the sieve plate 3 will sort and screen it. During this process, the motor 8 runs to drive the transmission rod 12 to rotate. The rotation of the transmission rod 12 drives the slider 14 to rotate together, and the slider 14 drives the linkage plate 6 to move through the clamping block 15. It should be noted that the connecting rod 11 fixedly connected to the outer wall of the linkage rod extends into the limiting groove 10. This enables the linkage plate 6 to move along the limiting groove 10 when it moves. Again, it should be noted that since the slider 14 can slide in the sliding groove 13, at this time, the linkage plate 6 will extend into the limiting groove 10 on the limiting ring 9 to rotate, so that the linkage plate 6 reciprocates above the sieve plate 3. In this way, the triangular push plate 7 arranged at the bottom of the linkage plate 6 reciprocally pushes and guides the aggregate, making the aggregate evenly distributed on the sieve plate 3, thereby increasing the sorting and screening effect and efficiency of the sieve plate 3 on the aggregate. After sorting, the aggregate will enter the discharge bin 5 respectively, thus completing the sorting of the aggregate.
[0024] Further, the push plates 7 in the same column are grouped together, and two adjacent groups of push plates 7 are arranged staggeredly;
[0025] Specifically, the push plate 7 not only has a triangular structure and can push the aggregate, but also the push plates 7 in the same column are grouped together, and two adjacent groups of push plates 7 are arranged staggeredly. This enables the push plate 7 of the previous group to push and guide the aggregate to move to both sides of the push plate 7 of this group and converge, and then be pushed by the push plate 7 of the next group to move to both sides of the push plate 7 of this group. This cycle is repeated, thereby increasing the pushing and guiding effect of the push plate 7 on the aggregate and enhancing the sorting and screening effect of the sieve plate 3 on the aggregate.
[0026] Further, rollers 16 are rotatably connected to the ends of the connecting rod 11 extending into the limiting groove 10, and the rollers 16 are in contact with the inner wall of the limiting groove 10;
[0027] Specifically, by providing the rollers 16 at the end of the connecting rod 11, the rollers 16 support the movement of the connecting rod 11 in the limiting groove 10, increasing the smoothness of its movement.
[0028] Further, the bottom of the limiting ring 9 is provided with a straight edge parallel to the sieve plate 3, and the shape of the limiting groove 10 corresponds to that of the limiting ring 9;
[0029] Specifically, the shape of the bottom of the limiting groove 10 corresponds to that of the limiting ring 9, so that the bottom of the limiting groove 10 is also a straight edge structure parallel to the sieve plate 3. This enables the push plate 7 to increase the pushing distance when pushing the aggregate on the sieve plate 3 when the linkage plate 6 drives the push plate 7 to move on the top of the sieve plate 3, thereby increasing the pushing and guiding effect of the push plate 7 on the aggregate.
[0030] Furthermore, when the push plate 7 moves cyclically with the linkage plate 6, the bottom of the push plate 7 contacts the top of the sieve plate 3 cyclically;
[0031] Specifically, the contact between the push plate 7 and the top of the sieve plate 3 can increase the pushing effect of the push plate 7 on the aggregate on the sieve plate 3, thereby preventing the aggregate from leaking through the gap between the push plate 7 and the sieve plate 3, resulting in the inability of the push plate 7 to push the aggregate.
[0032] Working principle: This embodiment provides an aggregate sorting device for road and bridge construction. The aggregate to be screened is placed into the feed bin 4, and then the aggregate will enter the sorting bin 2 along the feed bin 4 and be sorted and screened by the sieve plate 3. During this process, the motor 8 runs to drive the transmission rod 12 to rotate, the transmission rod 12 rotates to drive the slider 14 to rotate together, and the slider 14 drives the linkage plate 6 to move through the clamp 15. It should be noted that the connecting rod 11 fixedly connected to the outer wall of the linkage rod extends into the limiting groove 10, which enables the linkage plate 6 to move along the limiting groove 10 when it moves. Again, it should be noted that since the slider 14 can slide in the sliding groove 13, at this time, the linkage plate 6 will rotate along the limiting groove 10 on the limiting ring 9, so that the linkage plate 6 reciprocates above the sieve plate 3, so that the triangular push plate 7 provided at the bottom of the linkage plate 6 reciprocally pushes and guides the aggregate, so that the aggregate is evenly arranged on the sieve plate 3, thereby increasing the sorting and screening effect and efficiency of the sieve plate 3 on the aggregate. After sorting, the aggregate will enter the blanking bin 5 respectively, thus completing the sorting of the aggregate.
[0033] The embodiments disclosed in this utility model are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of this utility model according to the above embodiments and make different extensions and changes, but as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
