Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a concrete aggregate debris separation device. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] During concrete production, aggregates are transported to storage silos by trucks. Large aggregate particles are separated from the poured aggregate by a separating toothed plate inside the silo, ensuring uniform aggregate particles are stored in the silo and discharged onto a conveyor belt for mixing. However, large aggregate particles often remain stuck on the toothed plate and can easily become trapped in gaps, hindering discharge speed and preventing reuse. Therefore, this application designs a concrete aggregate debris separation device that ensures efficient discharge and enables the crushing and reuse of large aggregate particles to address this deficiency in the prior art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete aggregate debris separation device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete aggregate debris separation device, comprising a storage and unloading bin, a limiting groove, a crushing chamber, and a crushing roller.

[0006] The storage and unloading hopper is equipped with a separation plate;

[0007] The separation plate is provided with a plurality of separation holes, and separation tooth blocks are provided in the separation holes;

[0008] A lifting assembly is provided below the separating tooth block, and the lifting assembly drives the separating tooth block to separate from the separating hole;

[0009] It also includes servo motors.

[0010] Located outside the storage and unloading hopper, the servo motor drives the lifting assembly to move within the limiting groove;

[0011] It also includes discharge holes,

[0012] Located in the storage and unloading hopper, large aggregate particles enter the crushing chamber through the discharge hole, where they are crushed by a pair of crushing rollers before being discharged.

[0013] The above technical solution facilitates the separation of large aggregate particles through the separation holes, followed by the use of a servo motor to drive the separation teeth to peel the large aggregate particles into the crushing chamber, where they are then crushed and reused by the crushing rollers.

[0014] As a preferred embodiment of this utility model, the limiting groove is formed on the inner wall of the storage and unloading bin, horizontally to the separation hole, and is arranged along the straight opening direction of the separation hole.

[0015] By adopting the above technical solution, it is ensured that the servo motor can drive the separation tooth block to move horizontally along the separation hole.

[0016] As a preferred technical solution of this utility model, the separating tooth block is composed of a connecting rod and a plurality of tooth blocks. The tooth blocks are integrally connected to the connecting rod, and the tooth blocks move one-to-one in the separating hole. The tooth blocks are cuboids, but are not limited to cuboids.

[0017] The above technical solution facilitates the complete cleaning of aggregate from the separation hole by the separation tooth block.

[0018] As a preferred technical solution of this utility model, the lifting assembly includes a pair of telescopic rods installed below the separating tooth block for telescopic support;

[0019] It also includes an electric push rod, which pushes the separating tooth block to move up and down;

[0020] A loading plate is installed between the telescopic rod and the electric push rod. A threaded moving seat that slides within the limiting groove is connected to the loading plate. The servo motor drives the threaded moving seat to move back and forth.

[0021] By adopting the above technical solution, the lifting and lowering of the separating tooth block and the separation of the separating hole can be achieved.

[0022] As a preferred embodiment of this utility model, a threaded rod is installed on the output shaft of the servo motor, which is threadedly connected to the threaded moving seat and rotates in connection with the storage and unloading bin.

[0023] Using the above technical solution, the servo motor drives the threaded moving seat to rotate forward and backward on the threaded rod.

[0024] As a preferred embodiment of this invention, it also includes a limiting groove.

[0025] The crushing roller can move, adjust, and rotate within the limiting slide groove;

[0026] Limiting sliding hole,

[0027] The other end of the crushing roller passes through a surface located on the storage and unloading bin.

[0028] Drive motor,

[0029] Drive the crushing roller located on one side of the limiting sliding hole to rotate;

[0030] Hydraulic push rod,

[0031] It is assembled outside the storage and unloading bin, and a pair of crushing rollers are driven by a transmission component to move in opposite directions to adjust the crushing gap.

[0032] By adopting the above technical solution, the gap between a pair of crushing rollers can be adjusted by driving a hydraulic push rod.

[0033] As a preferred technical solution of this utility model, the transmission component includes a carrier plate mounted on the surface of the drive motor and a moving groove provided on the surface of the storage and unloading bin for the carrier plate to move. The lower end of the carrier plate is hinged with a rotating connecting rod.

[0034] The hydraulic push rod is connected to a hinge seat at its push rod end. The movement of the hinge seat causes the hinged rotating link to rotate, controlling the opening angle.

[0035] Using the above technical solution, the hydraulic push rod pushes the hinge seat to move, which drives the rotating connecting rod to rotate, and synchronously drives the carrier plate to move, thereby realizing the adjustment of the gap between the crushing rollers.

[0036] As a preferred technical solution of this utility model, when the hydraulic push rod is in the maximum contraction state, the two crushing rollers are in close contact with each other.

[0037] By adopting the above technical solution, the minimum crushing size for gap adjustment is guaranteed.

[0038] As a preferred embodiment of this utility model, a pair of guide plates with downwardly inclined upper surfaces are installed in the crushing chamber, and the guide plates are located below the discharge hole.

[0039] Using the above technical solution, large aggregate particles that are easy to peel off enter through the discharge hole and are guided into the crushing chamber by the guide plate.

[0040] As a preferred embodiment of this utility model, the lower surface of the storage and unloading bin is connected to a discharge seat that communicates with the crushing chamber, and a control box is installed on the surface of the storage and unloading bin.

[0041] The above technical solution facilitates the discharge of unloaded and crushed aggregates onto the conveyor belt.

[0042] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0043] 1. This concrete aggregate debris separation device uses a conveyor truck to dump aggregates into a storage and unloading bin. Large aggregate particles are isolated using separation holes. A servo motor, in conjunction with a lifting assembly, moves separation teeth along the separation holes, stripping large aggregate particles to the discharge hole and into the crushing chamber. Crushing rollers then crush the large aggregate particles for reuse, while preventing their accumulation and impact on discharge.

[0044] 2. This concrete aggregate debris separation device uses a hydraulic push rod to move the hinge seat, which in turn rotates the connecting rod to change its angle. This allows the connecting rod to engage with the crushing roller, causing the crushing roller to move within the limiting groove and limiting hole, thus adjusting the crushing gap between the crushing rollers. This facilitates adjustment of the crushing process according to the specified aggregate size. Attached Figure Description

Detailed Implementation

[0051] 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.

[0052] Please see Figures 1 to 3 The concrete aggregate debris separation device in this embodiment includes a storage and unloading bin 1 for dumping and collecting concrete aggregates; and a separation plate 2, which is installed and fixed inside the storage and unloading bin 1 to isolate and seal the interior of the storage and unloading bin 1. The separation plate 2 has multiple separation holes 3 to separate large aggregate particles from the dumped aggregates and to allow aggregate particles smaller than the diameter of the separation holes 3 to fall into the storage and unloading bin 1 for storage.

[0053] Separating tooth block 4 is located inside the separating hole 3. A lifting component is provided below the separating tooth block 4, and the lifting component drives the separating tooth block 4 to separate from the separating hole 3.

[0054] It should be added that the width of the separation plate 2 between the separation holes 3 is smaller than the gap between the separation holes 3, so that when the separation tooth block 4 moves in the separation hole 3, it can also drive the aggregate stuck on the separation plate 2 to move and peel off.

[0055] The lifting assembly includes a pair of telescopic rods 9 that are symmetrically distributed front and rear for telescopic support and are installed and fixed on the lower surface of the separating tooth block 4.

[0056] The telescopic rod 9 is composed of an outer cylinder and an inner rod that slide against each other to achieve the extension and retraction of the telescopic rod 9.

[0057] It also includes an electric push rod 10, the push rod of which is fixedly installed with the separating tooth block 4, and pushes the separating tooth block 4 to move up and down.

[0058] A loading plate 12 is installed and fixed between the other end of the telescopic rod 9 and the push rod of the electric push rod 10. One end of the loading plate 12 is connected and fixed to a threaded moving seat 8 that slides within the limiting groove 6. The servo motor 5 drives the threaded moving seat 8 to move back and forth.

[0059] The separating tooth block 4 consists of a connecting rod and a plurality of tooth blocks. The tooth blocks are integrally connected to the connecting rod. The tooth blocks move one-to-one within the separating hole 3. The tooth blocks are cuboids, but are not limited to cuboids.

[0060] It should be added that the separating tooth block 4 is connected and fixed to the push rod of the electric push rod 10 and the telescopic rod 9 via a connecting rod.

[0061] The servo motor 5 is assembled and fixed to the outside of the storage and unloading bin 1 by fastening screws, and drives the lifting assembly to move along the trajectory in the limit groove 6, so as to realize the separation tooth block 4 to move and lift along the separation hole 3 to peel off large particles of aggregate.

[0062] The limiting groove 6 is opened on the inner wall of the storage and unloading bin 1, horizontal to the separation hole 3, and is arranged along the straight opening direction of the separation hole 3.

[0063] A threaded rod 7, which is threadedly connected to the threaded moving seat 8 and rotates circumferentially with the storage and unloading bin 1, is installed and fixed at the output shaft of the servo motor 5.

[0064] The discharge hole 14 is located inside the storage and unloading bin 1. Large aggregate particles are stripped and enter the crushing chamber 13 through the discharge hole 14. The large aggregate particles are crushed by a pair of crushing rollers 17 driven to rotate inside the crushing chamber 13 before being discharged.

[0065] The crushing chamber 13 is connected to the discharge hole 14.

[0066] A pair of guide plates 11 with symmetrical left and right sides and downward inclined upper surfaces are installed and fixed in the crushing chamber 13. The guide plates 11 are located below the discharge hole 14. Large particles of aggregate that are easy to peel off fall into the guide plates 11 in the crushing chamber 13 through the discharge hole 14 and fall down the inclined surface to the crushing roller 17 for crushing.

[0067] Please see Figures 4 to 5 The device of this application also includes a limiting slide groove 15, which is opened on the inner wall of the storage and unloading bin 1, for the crushing roller 17 to move, adjust and rotate within the limiting slide groove 15; a limiting slide hole 16, which is opened on the front surface of the storage and unloading bin 1 for the other end of the crushing roller 17 to pass through; and a drive motor 18, which drives the crushing roller 17 located on one side of the limiting slide hole 16 to rotate.

[0068] The output shaft of the drive motor 18 is connected and fixed to the crushing roller 17.

[0069] The hydraulic push rod 21 is assembled and fixed to the front surface of the storage and unloading bin 1 by fastening screws. It drives a pair of crushing rollers 17 to move in opposite directions to adjust the crushing gap through the transmission component.

[0070] When the hydraulic push rod 21 is in its maximum retracted state, the two crushing rollers 17 are in contact with each other.

[0071] The transmission component includes a carrier plate 20 mounted and fixed on the surface of the drive motor 18 and a moving groove 19 formed on the front surface of the storage and unloading bin 1 for the carrier plate 20 to move. The lower end of the carrier plate 20 is hinged to a rotating connecting rod 23.

[0072] The hydraulic push rod 21 is connected and fixed to a hinge seat 22. The movement of the hinge seat 22 drives the hinged rotating link 23 to rotate, controlling the opening angle.

[0073] It should be added that, based on the calibrated size of the aggregate, when the hydraulic push rod 21 is activated to move the hinge seat 22, it drives the rotating connecting rod 23 to rotate and change the angle between them. When the rotating connecting rod 23 rotates, the carrier plate 20 rotates and drives the two carrier plates 20 to move in opposite directions, thereby driving the drive motor 18 and the crushing roller 17 to move synchronously, changing the gap between the crushing rollers 17, so as to ensure that after the large aggregate particles are stripped into the crushing chamber 13, the size of the aggregate crushed by the crushing rollers 17 meets the calibrated size of the stored aggregate.

[0074] The lower surface of the storage and unloading bin 1 is connected to a discharge seat 24 that is connected to the crushing chamber 13, so that the stored concrete aggregate and the crushed and recycled concrete aggregate can be discharged simultaneously through the discharge seat 24 to the conveyor belt for conveying and mixing. The surface of the storage and unloading bin 1 is equipped with a control box 25 for charging and powering the overall equipment, as well as system control of the electrical equipment.

[0075] The working principle of the above embodiments is as follows:

[0076] During use, concrete aggregate is dumped into the storage and unloading hopper 1 by a transport vehicle. The separation holes 3 on the separation plate 2 separate large aggregate particles, ensuring they are positioned on the separation plate 2. To prevent large aggregate particles from mating or getting stuck in the separation holes 3, the servo motor 5 is activated to rotate the threaded rod 7. Simultaneously, the threaded connection between the threaded moving seat 8 and the threaded rod 7, along with the limiting groove 6's limiting sliding of the threaded moving seat 8, ensures that the rotation of the threaded rod 7 moves the separation tooth block 4 connected to the telescopic rod 9 on the loading plate 12 along the separation holes 3, thus separating the large aggregate particles. The material is fixed and peeled into the discharge hole 14 and falls into the crushing chamber 13. (It should be noted that after the separating tooth block 4 moves to the leftmost position, the electric push rod 10 is activated, and in conjunction with the telescopic support of the telescopic rod 9, the separating tooth block 4 is moved down and separated from the discharge hole 14. Based on the above principle, the servo motor 5 is activated to drive the threaded rod 7 to reverse, so that the separating tooth block 4 moves back to the rightmost position. Then, the electric push rod 10 is activated to push the separating tooth block 4 up into the discharge hole 14, so that the next cleaning can be achieved. This cycle is repeated to peel large particles of aggregate into the crushing chamber 13.)

[0077] After the large aggregate particles enter the crushing chamber 13, the drive motor 18 is started to drive the crushing roller 18 to rotate, so that the large aggregate particles can be crushed and reused.

[0078] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
