Description

Technical Field

[0001] This utility model relates to the field of concrete quantitative filling technology, specifically a concrete filling device. Background Technology

[0002] Concrete is a widely used basic building material. It is mainly composed of cement, aggregates (sand and stone), water, and admixtures and additives added as needed, mixed in a certain proportion. With its high strength, durability, plasticity and cost-effectiveness, concrete plays an irreplaceable role in various projects.

[0003] In the construction of roads, bridges, and other engineering projects, concrete pouring is required for parts such as pavement, roadbed, and bridge piers to ensure the stability of the project. During the pouring process, it is necessary to accurately control the amount of concrete poured. Too much or too little concrete will affect the structural strength and increase construction costs. Currently, most concrete pouring devices first transport the concrete to a storage container and then use conveying devices such as screw pushers to deliver the concrete in a quantitative manner. However, this method often cannot completely remove the concrete from the container. The concrete residue in the container will accumulate over time, causing equipment blockage and affecting work efficiency. To address this, we have proposed a concrete pouring device.

[0017] 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.

[0018] Please see Figures 1 to 2 A concrete filling device includes a frame 1, a storage cylinder 2 for storing concrete to be filled is provided inside the frame 1, and a discharge cylinder 6 for discharging concrete is connected to the lower end of the storage cylinder 2. The device is characterized in that a valve assembly 3 is installed on the inner side wall of the discharge cylinder 6, and the valve assembly 3 is capable of opening and closing. The valve assembly 3 includes a valve plate 31 and a valve stem 32. The valve plate 31 is installed on the outside of the valve stem 32 and rotates around the valve stem 32 to close or open the discharge cylinder 6. One end of the valve stem 32 is rotatably connected to the inner wall of the discharge cylinder 6 and extends out. The valve plate 31 is circular. The valve plate 32 passes through the central axis of the valve plate 31 and divides the valve plate 31 into left and right parts. The valve plate 31 has an unfolded state and a closed state. When the valve plate 31 is in the unfolded state, both the left and right parts of the valve plate 31 are in a horizontal state. At this time, the outer circumference of the valve plate 31 is in contact with the inner wall of the discharge cylinder 6, and the discharge cylinder 6 is in a sealed state. When the valve plate 31 is in the closed state, both the left and right parts of the valve plate 31 are in a vertical state, and the inside of the discharge cylinder 6 is in an open state. The concrete inside the storage cylinder 2 can be transported out through the discharge cylinder 6. The storage cylinder 2 is equipped with a pressing component 5 at the top inside, which can push concrete. The pressing component 5 can slide up and down inside the storage cylinder 2. A transmission component 4 is provided between the top of the pressing component 5 and the inner wall of the frame 1. During the pressing process, the transmission component 4 can drive the valve plate 31 to rotate. When the pressing component 5 moves down, the concrete flows downward under the pressure of the pressing component 5. At this time, the valve plate 31 opens. When the pressing component 5 moves up, the valve plate 31 closes to prevent the concrete from continuing to flow downward. The valve plate 31 opens and closes rhythmically with the up and down movement of the pressing component 5, thereby realizing the quantitative filling of concrete.

[0019] The storage cylinder 2 is fixedly installed on the inner wall of the frame 1, and a hole penetrating the storage cylinder 2 and the frame 1 is provided on the side of the storage cylinder 2. A pipe for transporting concrete is installed in the hole. The hole of the storage cylinder 2 is located between the upper surface of the concrete layer and the lower surface of the pressing component 5. The pressing component 5 can pass through the hole during its up-and-down sliding process. When the pressing component 5 pushes the concrete, the internal pressure of the space between the concrete layer and the concrete increases, and at this time the valve plate 31 is in the open state, and the concrete is delivered through the valve plate 31. The remaining concrete will also move towards the valve plate 31 under pressure. When the pushing component 5 moves upward and passes through the hole, the hole connects the inside of the storage cylinder 2 with the outside, so that the pressure inside the storage cylinder 2 is the same as the pressure outside. The storage cylinder 2 is divided into an upper end and a lower end. The upper end is cylindrical and the lower end is conical. Both of them are hollow inside. The conical structure can guide the concrete to slide down the conical surface naturally under the action of gravity and the pushing component 5 through its inclined surface, forming a stable flow path and avoiding material accumulation that could cause blockage.

[0020] Please see Figure 3 The transmission assembly 4 includes a first transmission assembly 41, a second transmission assembly 42, and a drive assembly 43. The first transmission assembly 41 is disposed on the outer side wall of the discharge cylinder 6 and connected to the second transmission assembly 42. The second transmission assembly 42 is disposed between the outer side wall of the storage cylinder 2 and the inner side wall of the frame 1 and connected to the drive assembly 43. The drive assembly 43 is located above the pressing assembly 5 and disposed on the inner side wall of the frame 1. The drive assembly 43 can drive the first transmission assembly 41 through the second transmission assembly 42 for transmission.

[0021] Please see Figures 4 to 5The first transmission assembly 41 includes a fixing member 411, a sliding member 412, and a first piston 413. The fixing member 411 is fixedly installed on the outer wall of the discharge cylinder 6. The fixing member 411 is provided with a sliding groove. The sliding member 412 is disposed inside the fixing member 411 and is provided with a slider. The slider can be located in the sliding groove and slide up and down. One end of the first piston 413 passes through the fixing member 411 and is hinged to the outer wall of the sliding member 412. The other end is connected to the second transmission assembly 42. The first piston 413 can push the sliding member 412 to slide in the sliding groove of the fixing member 411. The sliding groove can restrict the direction of the sliding member 412 and can be converted into reciprocating linear motion of the sliding member 412 inside the fixing member 411.

[0022] The valve assembly 3 also includes a valve block 33, which is installed at the end of the valve stem 32 that protrudes from the inner wall of the discharge cylinder 6. The valve block 33 is provided with a locking post, and the sliding member 412 is provided with a fully penetrating locking groove. The locking post slides in the locking groove. When the locking post moves, it can drive the valve plate 31 to perform opening and closing movements. When the first piston 413 pushes the sliding member 412 to perform reciprocating linear movements, the locking post also slides in the locking groove. The locking post is connected to the valve stem 32, which can drive the valve stem 32 to rotate and drive the valve plate 31 to perform opening and closing movements.

[0023] Please see Figures 6 to 8 The second transmission assembly 42 includes a swing arm 421, a first connecting rod 422 and a second connecting rod 423. The two ends of the swing arm 421 are respectively hinged to one end of the first connecting rod 422 and the second connecting rod 423. The other end of the first connecting rod 422 is hinged to the first piston 413. The other end of the second connecting rod 423 is connected to the drive assembly 43.

[0024] The drive assembly 43 includes a motor 431 and a turntable 432. The motor 431 is fixedly mounted on the inner wall of the frame 1. The output end of the motor 431 is fixedly connected to the center of the turntable 432. A second connecting rod 423 is mounted on the other side of the turntable 432 opposite to the motor 431. The second connecting rod 423 is fixedly mounted on the surface of the turntable 432 off-center. A pushing assembly 5 is connected to the outer side of the end of the second connecting rod 423 connected to the turntable 432. The motor 431 can drive the turntable 432 to rotate. The second connecting rod 423 located off-center on the surface of the turntable 432 is also driven. The second connecting rod 423 can transmit the transmission to the first piston 413 through the swing arm 421 and the first connecting rod 422. The first piston 413 can drive the sliding member 412 to slide in the fixed member 411 and drive the valve plate to open and close.

[0025] The pressing assembly 5 includes a second piston 51 and a pressing rod 52. One end of the second piston 51 is hinged to the second connecting rod 423, and the other end is hinged to the pressing rod 52. The pressing rod 52 is located inside the storage cylinder 2 and is slidable. The outer wall of the pressing rod 52 is in close contact with the inner wall of the storage cylinder 2. When the turntable 432 rotates, the pressing rod 52 is driven by the second connecting rod 423 and the transmission is transmitted to the second piston 51. This can be converted into a reciprocating linear motion of the second piston 51 inside the storage cylinder 2, which continuously and regularly presses the concrete.

[0026] In summary, during use, this concrete filling device delivers concrete into the storage cylinder 2 through a pipe installed between the storage cylinder 2 and the frame 1. Under gravity, the concrete enters the discharge cylinder 6. At this time, the valve plate 31 is closed, and the second piston 51 is at its highest point during the upward movement. When the concrete is completely delivered, the motor 431 drives the turntable 432 to rotate. Simultaneously, the second connecting rod 423 is also driven, converting the rotation into reciprocating linear motion of the second piston 51 within the storage cylinder 2 via the push rod 52, causing the second piston 51 to begin pushing downwards. Concrete is transmitted to the first piston 413 via the swing arm 421 and the first connecting rod 422, which in turn transmits the power of the second connecting rod 423. The first piston 413 pushes the sliding member 412 to slide in the groove of the fixed member 411, and drives the locking pin to slide in the groove, thereby opening the valve plate 31. At this time, the concrete is pushed out of the discharge cylinder 6 under the action of gravity and the second piston 51. The second piston 51 reaches the lowest point in the pushing process and gradually moves upward under the action of the pushing rod 52. The valve plate 31 also gradually closes, thus completing a quantitative filling of concrete.
