Description

Technical Field

[0001] This utility model specifically relates to a concrete conveying device for infrastructure construction. Background Technology

[0002] In infrastructure construction, concrete conveying equipment is one of the core pieces of equipment, and its performance directly affects construction efficiency and concrete quality. Traditional concrete conveying devices typically use screw conveyors to achieve continuous concrete transport. However, in actual construction, concrete is prone to decreased fluidity due to moisture evaporation or fluctuations in mix proportions, requiring the replenishment of water during transport to maintain its workability. In existing technologies, some equipment uses manual or fixed water spraying devices. Fixed spraying positions can easily lead to localized over-wetting or dryness, affecting the homogeneity of the concrete. Utility Model Content

[0003] The present invention aims to solve, at least to some extent, one of the problems existing in the existing related technologies. To this end, the present invention proposes a concrete conveying device for infrastructure construction.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A concrete conveying device for infrastructure construction includes a frame and a conveying cylinder mounted on the frame. A water tank is connected to the upper side of the conveying cylinder. A plurality of water outlets are spaced apart on the lower side of the water tank along the conveying direction of the conveying cylinder. Water outlets are rotatably arranged inside the water outlets. Each water outlet has an inlet hole and an outlet hole. The inlet hole is located at the lower part of the water tank, and the outlet hole is located outside the water tank and faces the inner cavity of the conveying cylinder. The conveying cylinder includes a cylinder body and an auger that is rotatably arranged coaxially in the inner cavity of the cylinder body. A motor for driving the auger to rotate is provided at one end of the cylinder body. The conveying cylinder is provided with a transmission structure that can drive the plurality of water outlets to reciprocate synchronously with the rotation of the auger.

[0006] In one embodiment, the transmission structure includes a first transmission sprocket, a second transmission sprocket, a first bevel gear, a second bevel gear, a drive turntable, a first connecting rod, a movable rod, and a second connecting rod. The first transmission sprocket is coaxially mounted at one end of the auger and located outside the cylinder. The second transmission sprocket, the first bevel gear, and the second bevel gear are rotatably mounted on the frame. A chain is sleeved between the first and second transmission sprockets. The first bevel gear and the second transmission sprocket are coaxially mounted so that they rotate synchronously. The second bevel gear and the drive turntable... The turntables are arranged with a central axis so that they rotate synchronously. The first bevel tooth and the second bevel tooth mesh with each other. An eccentric shaft is provided on one side of the drive turntable. The movable rod is movably arranged on one side of the water tank and can reciprocate along the axial direction of the cylinder. The first connecting rod is hinged between the movable rod and the eccentric shaft. There are several second connecting rods, and each of the several second connecting rods is correspondingly arranged on one side of the water outlet. A vertical guide groove is opened through the second connecting rod. Several guide shafts are spaced apart on one side of the movable rod, and the several guide shafts are movably arranged in the vertical guide grooves.

[0007] In one embodiment, the water outlet of the water tank has a cross-section of an arc-shaped cavity, and a plurality of sealing strips are provided at intervals inside the arc-shaped cavity. The water outlet component is rotatably disposed in the arc-shaped cavity via a rotating shaft and abuts against the sealing strips. The second connecting rod is disposed on the rotating shaft and located outside the water tank.

[0008] In one embodiment, the water outlet has an atomizing nozzle.

[0010] In one embodiment, the cylinder has an inlet and an outlet.

[0011] In one embodiment, the feed inlet is connected to a hopper.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a motor to drive an auger to rotate, thereby enabling the concrete to be transported and moved. The rotational motion of the auger is then converted into the reciprocating oscillation of the water outlet through a transmission structure, so that the water spraying direction matches the concrete flow direction, achieving uniform coverage along the conveying path. This ensures that the concrete remains uniformly moist during transport, thus guaranteeing the homogeneity of the concrete. Attached Figure Description

[0017] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0018] like Figures 1 to 3 The concrete conveying device for infrastructure construction shown includes a frame 1 and a conveying cylinder 2 mounted on the frame 1. A water tank 3 is connected to the upper side of the conveying cylinder 2. Several water outlets are spaced apart on the lower side of the water tank 3 along the conveying direction of the conveying cylinder 2. Water outlets 4 are rotatably arranged inside the water outlets. Each water outlet 4 has an inlet hole 5 and an outlet hole 6. The inlet hole 5 is located at the lower part of the water tank 3, and the outlet hole 6 is located outside the water tank 3 and faces the inner cavity of the conveying cylinder 2. The conveying cylinder 2 includes a cylinder body 21 and an auger 22 rotatably mounted coaxially in the inner cavity of the cylinder body 21. A motor 23 is provided at one end of the cylinder body 21 to drive the auger 22 to rotate. The conveying cylinder 2 is provided with a transmission structure 7 that can drive the several water outlets 4 to reciprocate synchronously with the rotation of the auger 22.

[0019] Specifically, the auger is driven by a motor to rotate, thereby conveying and moving the concrete. The rotational motion of the auger is then converted into the reciprocating oscillation of the water outlet through a transmission structure, so that the water spray direction matches the concrete flow direction, achieving uniform coverage along the conveying path. This ensures that the concrete remains uniformly moist during conveying, thus guaranteeing the homogeneity of the concrete.

[0020] Further, the transmission structure 7 includes a first transmission sprocket 71, a second transmission sprocket 72, a first bevel gear 73, a second bevel gear 74, a drive turntable 75, a first connecting rod 76, a movable rod 77, and a second connecting rod 78. The first transmission sprocket 71 is coaxially mounted on one end of the auger 22 and located outside the cylinder 21. The second transmission sprocket 72, the first bevel gear 73, and the second bevel gear 74 are rotatably mounted on the frame 1. A chain 79 is sleeved between the first transmission sprocket 71 and the second transmission sprocket 72. The first bevel gear 73 and the second transmission sprocket 72 are coaxially mounted so that they rotate synchronously. The second bevel gear 74 and the first transmission sprocket 75 are coaxially mounted on the drive turntable 75, a first connecting rod 76, a movable rod 77, and a second connecting rod 78. The drive turntable 75 is arranged with a co-centered rotating axis so that the two rotate synchronously. The first bevel tooth 73 and the second bevel tooth 74 are mutually driven and meshed. An eccentric shaft 80 is provided on one side of the drive turntable 75. The movable rod 77 is movably arranged on one side of the water tank 3 and can reciprocate along the axial direction of the cylinder 21. The first connecting rod 76 is hinged between the movable rod 77 and the eccentric shaft 80. There are several second connecting rods 78, and several second connecting rods 78 are arranged one-to-one on one side of the water outlet 4. A vertical guide groove 81 is opened through the second connecting rod 78. Several guide shafts are spaced apart on one side of the movable rod 77, and several guide shafts are movably arranged one-to-one in the vertical guide groove 81.

[0021] Specifically, when the motor drives the auger to rotate, the first transmission sprocket drives the second transmission sprocket to rotate via a chain; the first bevel tooth coaxial with the second transmission sprocket meshes with the second bevel tooth, transmitting power to the drive turntable; the eccentric shaft of the drive turntable drives the movable rod to reciprocate relative to the water tank along the cylinder axis via the first connecting rod; the guide shaft on the movable rod slides in the vertical guide groove of the second connecting rod, thereby driving each water outlet to swing back and forth, causing the water outlet to periodically change the spray angle, forming dynamic spraying.

[0022] Concrete enters the cylinder through the feed inlet, and the rotating auger propels the concrete toward the discharge outlet. The synchronously oscillating water outlet sprays water mist evenly onto the concrete surface to maintain its fluidity. By adjusting the motor speed, the auger conveying speed and water spraying frequency can be controlled simultaneously to achieve adaptive adjustment.

[0023] Furthermore, the outlet cross-section of the water tank 3 is an arc-shaped cavity, with several sealing strips spaced apart inside the arc-shaped cavity. The water outlet component 4 is rotatably mounted inside the arc-shaped cavity via a rotating shaft and abuts against the sealing strips. The second connecting rod 78 is mounted on the rotating shaft and located outside the water tank 3. Thus, the arc-shaped cavity and the sealing strips cooperate to ensure that the water tank does not leak when the water outlet component rotates, reducing water waste.

[0024] Furthermore, the water outlet 6 is equipped with an atomizing nozzle. The atomizing nozzle inside the water outlet improves the uniformity of water mist mixing with concrete and avoids local clumping.

[0025] Furthermore, a water inlet pipe 83 is connected to one side of the water tank 3. A water pump can then be connected to the water inlet pipe to inject water.

[0026] Furthermore, the cylinder 21 has a feed inlet 84 and a discharge outlet 85.

[0027] Furthermore, the feed inlet 84 is connected to a hopper 86.
