[0024] The device is moved to the top of the floor to be poured, and after being moved into position, the operator connects the first delivery pipe with the pipeline of the concrete pump truck. Then, the pump truck is started, and concrete is pumped into the first delivery pipe.

[0028] The concrete contacts the V-shaped flow distribution block, blocks the flow of the concrete, and flows into the two flow distribution pipes. The aggregates in the two flows of concrete collide with each other when the concrete flows out of the two flow distribution pipes and flows into the discharge pipe again, so as to consume the kinetic energy of the aggregates and slow down the flow speed of the aggregates. The subsequent mortar contacts the aggregates, so as to wrap the aggregates with the mortar. Then, the concrete flows into the chute, and is poured on the top of the floor through the chute. By slowing down the falling speed of the aggregates, the mortar wraps the aggregates, so that the aggregates and the mortar of the concrete are uniformly distributed when the concrete is poured, the situation of local aggregation of the aggregates is reduced, and the mortar is effectively prevented from floating on the upper layer due to the fast falling speed of the aggregates, so as to affect the uniformity of the concrete distribution.

[0031] Wherein, since the concrete is delivered by a pump truck, it has a fast flow rate, when the concrete contacts the V-shaped flow splitter, the impact force generated by part of the concrete is relatively strong, when the concrete will have a relatively strong impact on the V-shaped flow splitter, it will push the V-shaped flow splitter to move, extrude the spring return rod to accumulate the elastic force, the spring return rod will push the piston block one and the piston block two to move, the piston block one will extrude the hydraulic oil in the connecting cylinder, flow to the top of the piston block two through the special-shaped groove, since the special-shaped groove has a plurality of asymmetric branch flow paths, it will force the hydraulic oil to flow, increase the flow resistance of the hydraulic oil, thereby slowing down the moving speed of the piston block one and the V-shaped flow splitter, slowing down the flow speed of the concrete, reducing the impact force, effectively preventing the concrete from flowing out of the flow splitter pipe, when the aggregate collides, the impact force of the aggregate is relatively strong, which may cause part of the aggregate to break, and it is difficult to form an effective skeleton.

[0032] Preferably, the blocking assembly comprises a concave-convex ring fixedly connected to the inner wall of the discharge pipe, a plurality of flow channel grooves are formed in the inner wall of the concave-convex ring;

[0033] Wherein, when the aggregates after mutual impact continue to flow in the discharge pipe, part of the aggregates will contact the concave-convex surface of the concave-convex ring, the concave-convex surface will increase the flow resistance of the aggregates, and part of the mortar will flow through the flow channel grooves, so that the mortar flows smoothly, thereby slowing down the flow speed of the aggregates near the concave-convex ring, allowing the aggregates located in the center of the discharge pipe to flow smoothly, causing the aggregates to have a speed difference, allowing the aggregates located in the center to contact the floor first, and part of the mortar will flow smoothly through the flow channel grooves, the flow speed of part of the mortar will be faster than that of the aggregates near the concave-convex ring, allowing part of the mortar to be poured on the top of the aggregates flowing in the center of the discharge pipe, forming a layer of aggregate-mortar-aggregate, allowing the aggregates to be staggered, and allowing the mortar to fully fill the gaps in the aggregates, making the distribution of the aggregates more uniform.

[0034] The present application has the following beneficial effects:

[0035] (1) When the present application is used, the operator connects the material conveying pipe one with the pipeline of the concrete pump truck, then starts the pump truck to pump the concrete into the material conveying pipe one, then the concrete flows into the material conveying pipe two and the turning pipe, until the concrete flows into the flow guide groove, and the concrete is divided into two streams through the flow splitting assembly, so that the aggregates in the two streams collide with each other to consume the kinetic energy of the aggregates, thereby slowing down the flow speed of the aggregates, and the subsequent mortar will wrap the aggregates, so that when the concrete is poured, the aggregates and the mortar of the concrete are uniformly distributed, reducing the local aggregation of aggregates, effectively preventing the aggregates from being easily accumulated at the bottom due to the relatively fast descending speed, causing the mortar to float on the upper layer, and affecting the uniformity of the concrete distribution.

[0036] (2) In this invention, because the concrete is transported by the pump truck, it has a relatively fast flow rate. When the concrete comes into contact with the V-shaped diversion block, some of the concrete generates a strong impact force. When the concrete has a strong impact on the V-shaped diversion block, it will push the V-shaped diversion block to move, squeeze the spring return rod, and make it accumulate rebound force. The spring return rod will push piston block one and piston block two to move. Through the buffer component, the moving speed of piston block one and V-shaped diversion block is slowed down, the flow rate of concrete is slowed down, and its impact force is reduced, effectively preventing concrete from flowing out of the diversion pipe. When the aggregates collide, the impact force of the aggregates is strong, which may cause some aggregates to break and make it difficult to form an effective skeleton.

[0037] (3) When the aggregates after mutual collision continue to flow in the discharge pipe, some aggregates will contact the concave and convex surfaces of the concave and convex rings. The concave and convex surfaces will increase the flow resistance of the aggregates, while some mortar will flow through the flow channel, allowing the mortar to flow smoothly. This slows down the flow speed of the aggregates near the concave and convex rings, allowing the aggregates located in the center of the discharge pipe to flow smoothly. This creates a speed difference in the aggregates, causing the aggregates located in the center to contact the floor slab first. Meanwhile, some mortar will flow smoothly through the flow channel, and the flow speed of some mortar will be faster than that of the aggregates near the concave and convex rings. This allows some mortar to be poured on top of the aggregates flowing in the center of the discharge pipe, forming a layer of aggregate-mortar-aggregate. This allows the aggregates to be arranged in an alternating manner, allowing the mortar to fully fill the gaps in the aggregates, making the aggregate distribution more uniform.

[0038] (4) In this invention, the concrete flows through the guide channel, which guides the aggregate in the concrete to gather. This causes the aggregate in the concrete to concentrate and contact the conical surface of the V-shaped diversion block. The symmetry of the conical surface guides the aggregate to flow along both sides of the conical surface, and the aggregate is evenly distributed. The V-shaped diversion block redistributes the aggregate, making the aggregate distribution in the two streams of concrete more uniform. This effectively prevents the aggregate from concentrating in the diversion pipe on one side during concrete transportation, causing uneven aggregate distribution and making it difficult for the aggregate to collide with each other, thus affecting the deceleration of the aggregate.
