[0002] A bridge abutment is a structure located at both ends of a bridge, supporting the bridge superstructure and connecting to the embankment. The abutment mainly consists of two parts: the cap and the body. The body is the main load-bearing part of the abutment and is usually made of masonry or concrete. When pouring concrete, a concrete pouring device is usually required. A concrete pouring device is a piece of equipment used in construction, mainly used to pour concrete evenly and efficiently to a designated location.

[0003] Chinese utility model application No. 202322050821.3 discloses a concrete pouring pump, including a body, a connecting pipe connected to the surface of the body, a metal hose connected to the surface of the connecting pipe, a discharge port connected to the surface of the metal hose, and the surface of the discharge port being fitted inside a support frame. A connecting block is engaged inside the support frame, and a slider is engaged at the bottom of the connecting block. However, in actual use, due to the viscosity of concrete, it tends to accumulate after falling onto the top of the screen plate, resulting in a slower rate of concrete entering the hopper and thus lower pumping efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a concrete pouring device for bridge abutments to solve the problem of low pumping efficiency caused by concrete accumulating on the top of the sieve plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete pouring device for bridge abutments, comprising a pumping body, a feeding hopper connected to one side of the pumping body, an embedding groove on the top of the feeding hopper, and a shaking device installed in the embedding groove, the shaking device comprising a mounting plate and a mounting frame, a motor fixedly mounted on the top of the mounting plate, a rotating rod connected to the output shaft of the motor, a cam connected to the outer wall of the rotating rod, stroke grooves on both sides of the inner wall of the mounting frame, sliders slidably connected in the stroke grooves, and a common screen plate connected between the two sliders, a connecting plate connected to the bottom of the screen plate, two baffles connected to the bottom of the connecting plate, the screen plate being a filter plate, and multiple guide frames connected to the top of the screen plate.

[0006] As a further description of the above technical solution:

[0007] One side of the mounting plate is connected to the outer wall of the feeding hopper, and the mounting bracket is installed in the embedded groove.

[0008] As a further description of the above technical solution:

[0009] The motor output shaft extends into the feeding hopper, and the end of the rotating rod away from the motor is rotatably connected to one side of the inner wall of the feeding hopper.

[0010] As a further description of the above technical solution:

[0011] The cam is located between two baffles, and the cam protrusion is in indirect contact with one side of the baffle.

[0012] As a further description of the above technical solution:

[0013] Both sides of the sieve plate are provided with sealing devices. The sealing device includes a movable groove, which is opened on one side of the sieve plate. A sealing plate is slidably connected in the movable groove. Multiple springs are connected to one side of the sealing plate, and the other end of the multiple springs is connected to one side of the inner wall of the movable groove. One side of the sealing plate is in contact with one side of the inner wall of the mounting frame.

[0014] As a further description of the above technical solution:

[0015] Limiting grooves are provided on both sides of the inner wall of the movable groove, and limiting blocks are slidably connected in the limiting grooves. One side of the limiting block is connected to one side of the sealing plate.

[0016] As a further description of the above technical solution:

[0017] The sealing plate has multiple fixing grooves on one side, and a fixing rod is slidably connected in the fixing groove. The other end of the fixing rod is connected to one side of the inner wall of the movable groove, and a spring is sleeved on the outside of the fixing rod.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting up a shaking device, the motor drives the rotating rod to rotate, and the rotating rod drives the cam to rotate, so that the cam protrusion intermittently squeezes the baffle, causing the baffle to shake back and forth, thereby causing the baffle to drive the screen plate to shake through the connecting plate, so that the concrete on the top of the screen plate falls faster due to the shaking of the screen plate, thereby ensuring the amount of concrete in the feeding hopper, and thus ensuring the pumping efficiency.

[0020] 2. In this utility model, by setting a sealing device, the sealing plate on one side of the screen plate moves inward and squeezes the spring by shaking the screen plate left and right, while the sealing plate on the other side of the screen plate extends out by the spring's rebound, so that the sealing plate fits tightly against the inner wall of the mounting frame, thereby preventing concrete from falling to both sides of the screen plate when the screen plate shakes, thus avoiding obstruction and affecting the movement of the screen plate.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 - Figure 5This utility model provides a technical solution: a concrete pouring device for bridge abutments, comprising a pumping body 1, a feeding hopper 2 connected to one side of the pumping body 1, an embedded groove 3 on the top of the feeding hopper 2, and a shaking device 4 installed in the embedded groove 3, the shaking device 4 comprising a mounting plate 402 and a mounting frame 407, a motor 401 fixedly mounted on the top of the mounting plate 402, a rotating rod 403 connected to the output shaft of the motor 401, a cam 405 connected to the outer wall of the rotating rod 403, and stroke grooves 410 on both sides of the inner wall of the mounting frame 407, with sliders 409 slidably connected in the stroke grooves 410. The sliders 409 are connected by the same screen plate 408. The bottom of the screen plate 408 is connected to a connecting plate 406. The bottom of the connecting plate 406 is connected to two baffles 404. The screen plate 408 is a filter plate. The top of the screen plate 408 is connected to multiple guide frames 6. One side of the mounting plate 402 is connected to the outer wall of the feeding hopper 2. The mounting frame 407 is installed in the embedding groove 3. The output shaft of the motor 401 extends into the feeding hopper 2, and the end of the rotating rod 403 away from the motor 401 is rotatably connected to one side of the inner wall of the feeding hopper 2. The cam 405 is located between the two baffles 404, and the protrusion of the cam 405 is indirectly in contact with one side of the baffle 404.

[0029] In a specific implementation, a shaking device 4 is provided, which drives the rotating rod 403 to rotate via the output shaft of the motor 401. The rotating rod 403 drives the cam 405 to rotate, causing the cam 405 to press the baffle 404 through the protrusion. This causes the two baffles 404 to be intermittently subjected to force and to shake back and forth. As a result, the baffles 404 drive the connecting plate 406 to move, and the connecting plate 406 drives the screen plate 408 to shake. This causes the concrete on the top of the screen plate 408 to fall more quickly due to the shaking of the screen plate 408, thereby ensuring pumping efficiency. By setting the slider 409 to slide within the stroke groove 410, the screen plate 408 is made more stable when moving, thereby improving the stability of the device during operation. By setting the guide frame 6, the guide frame 6 can disperse and guide the concrete, preventing the concrete from accumulating in one place, thereby further improving the concrete discharge rate.

[0030] Both sides of the sieve plate 408 are provided with sealing devices 5. The sealing device 5 includes a movable groove 501, which is opened on one side of the sieve plate 408. A sealing plate 502 is slidably connected in the movable groove 501. Multiple springs 505 are connected to one side of the sealing plate 502, and the other end of the multiple springs 505 is connected to one side of the inner wall of the movable groove 501. One side of the sealing plate 502 is in contact with one side of the inner wall of the mounting frame 407. Limiting grooves 503 are opened on both sides of the inner wall of the movable groove 501, and limiting blocks 504 are slidably connected in the limiting grooves 503. One side of the limiting block 504 is connected to one side of the sealing plate 502. Multiple fixing grooves are opened on one side of the sealing plate 502, and fixing rods 506 are slidably connected in the fixing grooves. The other end of the fixing rods 506 is connected to one side of the inner wall of the movable groove 501, and the springs 505 are sleeved on the outside of the fixing rods 506.

[0031] In a specific implementation, by setting a sealing device 5, when the screen plate 408 sways left and right, and moves to one side, the sealing plate 502 in the movable groove 501 on one side moves inward by pressing against the inner wall of the mounting frame 407 and compresses the spring 505, causing the spring 505 to generate a rebound force. By setting a fixing rod 506 to support the spring 505, the spring 505 is prevented from bending when compressed, thus avoiding affecting the rebound effect. However, the sealing plate 502 on the other side of the screen plate 408 extends out due to the rebound of the spring 505 that was previously compressed, thus making the sealing plate 502 fit tightly against the inner wall of the mounting frame 407. This prevents concrete from falling to both sides of the screen plate 408 when the screen plate 408 sways, thus avoiding obstruction and affecting the movement of the screen plate 408. By setting a limiting block 504 to slide in the limiting groove 503, the sealing plate 502 is prevented from deviating and jamming when moving, thus avoiding affecting its use.

[0032] Working principle: During use, concrete is transported to the top of the screen plate 408 by a transport vehicle. Then, the motor 401 drives the rotating rod 403 to rotate, which in turn drives the cam 405 to rotate. The cam 405 squeezes through the protrusion, causing the baffle 404 to move left and right. This causes the baffle 404 to move the connecting plate 406, which in turn causes the screen plate 408 to sway back and forth. This causes the concrete on the top of the screen plate 408 to fall more quickly due to the swaying of the screen plate 408, ensuring pumping efficiency. When the screen plate 408 moves left and right, it squeezes the sealing plate 502 on one side, causing the sealing plate 502 to move inward in the movable groove 501. The sealing plate 502 on the other side of the screen plate 408 moves outward due to the rebound force of the spring 505. This ensures that one side of the sealing plate 502 is always in contact with the inner wall of the mounting frame 407, preventing concrete from falling between the screen plate 408 and the mounting frame 407 and affecting the movement of the screen plate 408.
