Description

Technical Field

[0001] This utility model relates to the field of paver technology, specifically to a vibratory feeding device for a slipform paver. Background Technology

[0002] Slipform pavers are highly efficient automated equipment used for the construction of cement concrete pavements. They are mainly used for continuous paving operations in projects such as highways, airport runways, curbs, and crash barriers.

[0003] Currently, slipform pavers are equipped with conveyor belts on their feed hoppers. These conveyor belts transport concrete discharged from concrete mixer trucks to the paver for continuous paving operations. However, the current feeding structure (conveyor belt) is simple and lacks a side interception function. During the feeding process, concrete easily falls onto the ground from both sides of the conveyor belt, resulting in concrete waste. Furthermore, a large number of driven rollers are typically installed in the middle of the conveyor belt, but the distance between these rollers is relatively large. This causes the conveyor belt to sink during concrete transport, resulting in concrete accumulation in that area and increased energy consumption during transport. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a vibratory feeding device for a slipform paver, which can block the gap between the trough and the conveyor belt through the bearing plate and the C-shaped rod, and can also support the conveyor belt through the bearing plate, so as to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a vibratory feeding device for a slipform paver, comprising a trough installed on the paver's feed hopper, wherein the trough contains an annular conveyor belt, both sides of which are raised outward to form blocking parts, and a conveying trough is formed between the conveyor belt and the blocking parts. The conveyor belt contains a bearing plate, and both ends of the bearing plate are provided with driven rollers and driving rollers.

A discharge trough is installed at the other end of the tank body, and the other end of the discharge trough is located above the feeding hopper.

[0007] As a preferred technical solution, a U-shaped groove is provided on the inner wall of the tank. One end of the U-shaped groove is open and the other end is sealed. Inside the U-shaped groove, there is a U-shaped collection tank. The inner side of the collection tank is flush with the inner side of the tank. The end of the collection tank away from the opening of the U-shaped groove is in contact with the inner wall of the U-shaped groove. A handle is installed on the end of the collection tank facing the opening of the U-shaped groove. A screw hole is provided on one side of the tank. A screw rod is threaded into the screw hole.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a vibratory feeding device for a slipform paver according to this utility model includes a trough 1 installed on the paver's feed hopper. The trough 1 has an annular conveyor belt 2 inside. Both sides of the conveyor belt 2 are raised outward to form blocking parts. A conveying groove is formed between the conveyor belt 2 and the blocking parts. The conveyor belt 2 has a bearing plate 14 inside. Both ends of the bearing plate are provided with driven rollers 17 and driving rollers 21. Both ends of the driven rollers 17 and driving rollers 21 are expanded outward to form conical support parts 18. Both sides of the bearing plate 14 are raised to form sealing parts 15. The support parts 18 and sealing parts 15 are both in contact with the inner side of the blocking parts. C-shaped rods 19 are provided on the outer side of the sealing parts 15. The outer end faces of the C-shaped rods 19 and the sealing parts 15 are both installed on the trough 1.

[0020] In this embodiment, a feeding hopper 3 is installed at one end of the tank body 1, and the feeding hopper 3 is arranged opposite to the conveying trough. A discharge trough 12 is installed at the other end of the tank body 1, and the other end of the discharge trough 12 is arranged above the feeding hopper.

[0021] The discharge chute is inclined downwards, allowing concrete to quickly enter the feed hopper along the inclined discharge chute.

[0022] In this embodiment, a U-shaped groove 4 is provided on the inner wall of the tank 1. One end of the U-shaped groove 4 is open and the other end is sealed. Inside the U-shaped groove 4, there is a U-shaped collection groove 5. The inner side of the collection groove 5 is flush with the inner side of the tank 1. The end of the collection groove 5 away from the opening of the U-shaped groove 4 is in contact with the inner wall of the U-shaped groove 4. A handle 6 is installed at the end of the collection groove 5 facing the opening of the U-shaped groove 4. A screw hole is provided on one side of the tank 1. A screw rod is threaded into the screw hole. One end of the screw rod is in contact with the end face of the collection groove 5. A handwheel 7 is installed at the other end of the screw rod.

[0023] In this embodiment, multiple ball grooves are provided on the surfaces of the bearing plate 14 and the sealing part 15. A ball 16 is movably installed in each ball groove. A portion of the ball 16 extends to the outside through the opening of the ball groove and contacts the inner side of the conveyor belt 2. The ball reduces the friction between the bearing plate and the conveyor belt, which can drive the rotation of the conveyor belt more smoothly.

[0024] In this embodiment, mounting holes are provided on both sides of the trough 1, opposite to the driving roller 21 and the driven roller 17. Sealed bearings 8 are installed in the mounting holes. The roller shafts on the driving roller 21 and the driven roller 17 are installed in the inner ring of the sealed bearings 8. A motor 13 is installed on one side of the trough 1, and the rotating shaft of the motor 13 is fixedly connected to the roller shaft on the driving roller 21.

[0025] In this embodiment, a fixing plate 10 is installed on the bottom surface of the tank 1. Multiple reinforcing plates are installed between the fixing plate 10 and the tank 1. The fixing plate 10 is provided with multiple fixing holes, and bolts can pass through the fixing holes to fix the fixing plate to the feed hopper.

[0026] In this embodiment, a vibrator 20 is installed on the bottom surface of the support plate 14, and disassembly ports 9 are provided on both sides of the trough 1 directly opposite the vibrator 20, which facilitates the disassembly and assembly of the vibrator.

[0027] When in use, start the vibrator and motor. The motor starts the drive roller and the conveyor belt, which makes the conveyor belt rotate. The concrete discharged from the concrete mixer truck can be discharged into the feeding hopper until it flows onto the conveyor belt. The rotating conveyor belt can drive the concrete towards the feeding hopper until it is discharged into the feeding hopper through the discharge chute.

[0028] The vibration energy generated by the vibrator acts on the bearing plate, and the vibration energy on the bearing plate acts on the conveyor belt. The vibration energy flattens the concrete on the surface of the conveyor belt, avoiding the accumulation of clumps and thus reducing energy consumption.

[0029] The support plate prevents the conveyor belt from sinking during rotation, while the trough intercepts the sides of the conveyor belt to prevent concrete from falling to the ground. The sealing part and C-shaped rod seal the gap between the conveyor belt and the trough, and the raised sides of the conveyor belt form a "︺" shaped conveyor trough on the conveyor belt, which causes the concrete to gather in the middle, further preventing concrete from falling from the sides.

[0030] The trough is equipped with a collection trough. After the conveyor belt rotates from the upper surface to the lower surface, some concrete will inevitably remain on the conveyor belt. The collection trough can collect the concrete that falls at this time, avoiding waste. After a certain amount is collected, the screw is rotated by handwheel. After the screw is removed from the U-shaped trough, the collection trough can be pulled out by handle, which facilitates the subsequent processing of the concrete inside the collection trough.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
