[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 concrete pump truck with anti-clogging function, including a concrete pump truck hopper 1, a limiting platform 3 is provided inside the concrete pump truck hopper 1, and a grid filter plate 10 for filtering concrete material is connected to the surface of the limiting platform 3; a material feeding component to prevent concrete material from clogging is provided inside the concrete pump truck hopper 1, and the feeding rod 6 of the feeding component is fitted with the surface of the grid filter plate 10 with a clearance fit; limiting plates 12 are connected to both sides of the grid filter plate 10 through connecting plates 11, and an assembly seat 13 is installed on the surface of the limiting plate 12, and an anti-detachment positioning component for fixing the position of the grid filter plate 10 is provided inside the assembly seat 13; and a baffle plate 2 is installed on one side of the top of the concrete pump truck hopper 1.

[0022] It is worth noting that, through the coordinated arrangement of the concrete pump truck hopper 1, grid filter plate 10, limit plate 12, material feeding component, and anti-detachment positioning component, the accumulation and blockage of concrete in the hopper can be effectively reduced during use, ensuring the efficiency of the concrete pump truck in pumping concrete. At the same time, the grid filter plate 10 can be easily disassembled and installed for cleaning and maintenance, improving maintenance efficiency.

[0023] The material feeding assembly includes: a transmission rod 5 rotatably mounted inside the concrete pump truck hopper 1, and a transmission disc 7 mounted on one end of the transmission rod 5; wherein, the transmission disc 7 is located on the outside of the concrete pump truck hopper 1, and a servo motor 8 is mounted on one side of the concrete pump truck hopper 1. The output end of the servo motor 8 is connected to the transmission disc 7 via a transmission belt, and material feeding rods 6 are distributed on the surface of the transmission rod 5.

[0024] Furthermore, the transmission rod 5 is a structure for installing and transmitting the material feeding rod 6, and the transmission disc 7 is a transmission connection between the transmission rod 5 and the output end of the servo motor 8. The servo motor 8 drives the transmission disc 7, which can drive the transmission rod 5 to rotate, causing the material feeding rod 6 to rotate and move within the gap on the surface of the grid filter plate 10 to feed the concrete, effectively preventing blockage.

[0025] Specifically, a positioning rod 4 is installed on the top of the concrete pump truck hopper 1, and the top of the positioning rod 4 is movably inserted into the connecting plate 11. The positioning rod 4 cooperates with the connecting plate 11 to position the grid filter plate 10, and together with the limiting platform 3, it provides support for the grid filter plate 10, which can further improve the stability of the grid filter plate 10.

[0026] Anti-detachment positioning components: a positioning plate 14 movably installed inside the assembly base 13, and an adjusting screw 17 threadedly connected to the assembly base 13; wherein, a positioning sleeve 16 is installed on the surface of the positioning plate 14, one end of the adjusting screw 17 is connected to a limiting plate 18, and the surface of the limiting plate 18 is rotatably connected to the inner wall of the positioning sleeve 16.

[0027] In addition, the positioning plate 14 works with the positioning base 9 to lock and position the grid filter plate 10. The adjusting screw 17 is a structure that controls the positioning plate 14. The positioning sleeve 16 works with the limiting plate 18 to limit the adjusting screw 17. By rotating the adjusting screw 17, the positioning plate 14 can be pushed into the positioning base 9 to achieve the positioning effect.

[0028] The assembly base 13 is internally equipped with an anti-loosening spring 19, which is fitted onto the surface of the adjusting screw 17. Guide rods 15 are connected to both sides of the material-pulling rod 6 on the surface of the positioning plate 14, and the surfaces of the guide rods 15 are slidably connected to the assembly base 13. The anti-loosening spring 19 is a structure that maintains the action on the positioning plate 14, ensuring the stability of the positioning plate 14's clamping. The guide rods 15 guide and limit the movement of the positioning plate 14.

[0029] The servo motor 8 of the material feeding assembly drives the transmission rod 5 to engage the material feeding rod 6 with the grid filter plate 10, enabling dynamic material feeding. This reduces the accumulation and clumping of concrete material, effectively preventing aggregate jamming or clogging of the grid holes, further improving pumping continuity and reducing the frequency of downtime for cleaning. The positioning plate 14 and adjusting screw 17 of the anti-detachment positioning assembly engage with the positioning seats 9 on both sides of the concrete pump truck hopper 1. The grid filter plate can be quickly disassembled by simply rotating the adjusting screw 17, facilitating cleaning or replacement. Furthermore, the anti-loosening spring 19 on the surface of the adjusting screw 17 further prevents the adjusting screw 17 from loosening due to vibration, ensuring a stable engagement between the positioning plate 14 and the positioning seat 9, and improving the efficiency of cleaning and maintenance.
