Abstract

Technical Field
[0001] This utility model relates to the field of concrete pump truck technology, specifically to a material feeding device for a concrete pump truck. Background Technology
[0002] A concrete pump truck is a machine that uses pressure to continuously transport concrete along pipelines. In concrete pouring or spraying operations, the concrete is first mixed in a concrete mixer, then transported to the hopper of the concrete pump truck, and finally pumped to the work surface for pouring or spraying. However, when a concrete pump truck is pumping concrete, the high-speed flow of the concrete and the pumping pressure can cause concrete to splash and segregate when it hits the formwork. This not only affects the quality of the concrete pouring but also poses a safety hazard as the splashed concrete may injure workers.

The water pump is fixedly connected to the front side of the protective cover; the water tank is fixedly connected to the front side of the protective cover; the rotating shaft is fixedly connected to the inner wall of the protective cover; the guide plate is rotatably connected to the rotating shaft; and the first spring is fixedly connected between the guide plate and the inner wall of the protective cover.
[0004] The cited patent reveals the aforementioned problems in the prior art, therefore we need to propose a feeding device for concrete pump trucks. Utility Model Content

[0020] 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.
[0021] Please see Figure 1-4This utility model provides: a feeding device for a concrete pump truck, including a feeding conveying cylinder 1 and a pressure reducing and diverting pipe 8 for diverting and slowing down the pumped concrete; the top of the pressure reducing and diverting pipe 8 is connected to a connecting main pipe 5, and the surface of the connecting main pipe 5 is provided with a clamping assembly that connects to the feeding conveying cylinder 1; an impact-resistant diverting block 9 is provided on the inner wall of the pressure reducing and diverting pipe 8 below the connection of the connecting main pipe 5; the two sides of the impact-resistant diverting block 9 are connected to the bottom of the inner wall of the pressure reducing and diverting pipe 8 with mounting base plates 10, and the surface of the mounting base plates 10 is provided with a buffer assembly that reduces the impact force of the concrete pumping; the bottom of the pressure reducing and diverting pipe 8 is connected to a discharge pipe 11 for feeding concrete material at the center position.
[0022] It is worth noting that, through the coordinated arrangement of structures such as the feeding conveyor cylinder 1, connecting main pipe 5, pressure reducing diversion pipe 8, impact-resistant diversion block 9, discharge pipe 11, clamping assembly, and buffer assembly, the concrete flow rate at the discharge port can be effectively reduced during concrete pumping, further reducing concrete splashing and ensuring the quality of concrete pouring. At the same time, it improves the safety of feeding and prevents workers from being injured by splashing.
[0023] The mounting assembly includes: a limiting block 6 connected to the top of the connecting main pipe 5, and a connecting sleeve 2 installed on the outer surface of the feeding conveyor cylinder 1; wherein, the surface of the connecting sleeve 2 is provided with a limiting seat 3, the connecting main pipe 5 is sleeved on the surface of the feeding conveyor cylinder 1, and the surface of the limiting block 6 is movably locked onto the inner wall of the limiting seat 3. The surface of the limiting block 6 is provided with a locking hole 7, and the surface of the limiting seat 3 is movably mounted with a locking element 4 that connects to the inner wall of the locking hole 7.
[0024] In addition, the connecting main pipe 5 is a pipe connected to the feeding conveyor cylinder 1, which facilitates the transportation of the concrete pumped inside the feeding conveyor cylinder 1 to the pressure reducing and diverting pipe 8 through the connecting main pipe 5, thereby dispersing the impact force of the concrete. The limiting bracket 3 is a structure that is installed in conjunction with the limiting block 6. The locking hole 7 is used in conjunction with the locking part 4 to fix the limiting block 6 inside the limiting bracket 3, which facilitates quick installation and disassembly and makes it easy to replace and maintain.
[0025] The buffer assembly includes: a buffer guide plate 14 movably mounted on the surface of the mounting base plate 10, and a limiting plate 15 connected to the bottom of the buffer guide plate 14; wherein, limiting grooves 12 are formed on both sides of the surface of the mounting base plate 10, and the limiting plate 15 is slidably inserted into the inner wall of the limiting groove 12.
[0026] Furthermore, the mounting base plate 10 is a structure for assembling the buffer guide plate 14, which facilitates the buffer guide plate 14 in reducing the impact force of falling concrete. The limiting plate 15 is a structure that limits and guides the buffer guide plate 14, ensuring the stability of the buffer guide plate 14.
[0027] Connecting rods 16 are distributed at the bottom of the buffer guide plate 14. The bottom end of the connecting rod 16 is connected to an anti-detachment component 17. A buffer spring 18 is fitted on the surface of the connecting rod 16. The bottom end of the buffer spring 18 is connected to the top of the mounting base plate 10. The surface of the mounting base plate 10 is provided with an assembly guide hole 13. The connecting rod 16 is fitted into the assembly guide hole 13.
[0028] The connecting rod 16 is a structure that works in conjunction with the buffer spring 18 to reduce the speed when the concrete falls. The anti-detachment component 17 works in conjunction with the connecting rod 16 to limit the position of the buffer guide plate 14 and prevent the buffer guide plate 14 from falling off due to the force of the buffer spring 18. The assembly guide hole 13 is a structure that guides the installation of the connecting rod 16.
[0029] Specifically, control handles 19 are installed on both sides of the pressure-reducing diversion pipe 8, and symmetrical material inlets are opened on the inner surface of the pressure-reducing diversion pipe 8, which are connected to the discharge pipe 11. The addition of control handles 19 on both sides of the pressure-reducing diversion pipe 8 makes it easy for operators to adjust the pipe angle or position, improves the flexibility of on-site operation, and adapts to the needs of complex working conditions; moreover, the material inlets on both sides of the pressure-reducing diversion pipe 8 cooperate with the central discharge pipe 11 to make the concrete evenly diverted and then converged for output. This not only allows the concrete material to be flushed during discharge to reduce the impact force of feeding, but also reduces the risk of material blockage, ensuring the continuity of feeding and construction efficiency.
[0030] By engaging the limiting block 6 of the clamping assembly with the connecting sleeve 2, and combining the locking hole 7 and the locking piece 4, the feeding conveyor cylinder 1 and the connecting main pipe 5 can be quickly connected or separated, facilitating disassembly, assembly, and subsequent maintenance and replacement. Through the pressure reducing diversion pipe 8 and the internal impact-resistant diversion block 9, the impact force of the concrete is effectively dispersed and the flow rate is reduced, thus reducing wear on the pipe wall. At the same time, in conjunction with the buffer guide plate 14, the bottom buffer spring 18 and the sliding structure of the limiting groove, along with the limiting plate 15 and the connecting rod 16, move to dynamically adjust the impact force of the falling concrete, avoiding material splashing caused by hard collisions and reducing the risk of injury to workers from splashing. Furthermore, the material inlets on both sides of the pressure reducing diversion pipe 8 cooperate with the central discharge pipe 11 to ensure that the concrete is evenly diverted and then converged for output. This not only reduces the impact force of the concrete material during discharge but also reduces the risk of material blockage, ensuring continuous feeding and construction efficiency.
