[0031] The utility model provides Figures 1 to 3A large-volume concrete pouring device shown in the figure includes a unloading platform 1, a feed hopper 11 is fixedly connected to the surface of the unloading platform 1, and a feeding mechanism is provided at the front end of the unloading platform 1. The feeding mechanism includes an equipment box 12, a transmission shaft 13, a winch 14, a transmission steel cable 15, an equipment motor 16, a positioning rod 2, a positioning groove 21, a transport bucket 3, a positioning roller 33 and a connecting block 34. The equipment box 12 is fixedly connected to the front end position of the upper surface of the unloading platform 1, and two groups of positioning rods 2 are provided. The two groups of positioning rods 2 are fixedly connected to the front end position of the lower surface of the unloading platform 1, and the transport bucket 3 is arranged between the two groups of positioning rods 2.

[0032] Among them, the unloading platform 1 is installed at the upper end of the steep slope, and then the positioning rod 2 is fixed to the side of the steep slope, so that the upper end of the positioning rod 2 is fixed to the unloading platform 1, and the transport bucket 3 is installed between the two groups of positioning rods 2. During the pouring process, the concrete is transported to the surface of the unloading platform 1 by an engineering vehicle, and then the concrete is poured into the interior of the transport bucket 3. At this time, the feeding mechanism transports the transport bucket 3 along the steep slope to the lower side of the mountain to pour the dam, which facilitates the transportation and pouring of concrete and improves the transportation and pouring efficiency of the dam.

[0033] See Figures 2 to 4 The transmission shaft 13 is rotatably connected to the left and right inner walls of the equipment box 12. Two groups of winches 14 are provided. The two groups of winches 14 are fixedly connected to the left and right ends of the transmission shaft 13 respectively. The transmission steel cable 15 is wound around the surface of the winch 14. The equipment motor 16 is fixedly installed at the right end of the equipment box 12. The output end of the equipment motor 16 is fixedly connected to the right end of the transmission shaft 13. The front end of the unloading platform 1 is located at the lower side of the equipment box 12 and has two groups of limiting holes 17. The lower end of the transmission steel cable 15 passes through the limiting holes 17 and is fixedly connected to the connecting block 34. The connecting block 34 is fixedly connected to the upper surface of the transport bucket 3. A feed port 31 is provided on the upper surface of the transport bucket 3. A discharge pipe 32 is fixedly connected to the lower end of the transport bucket 3. The left and right surfaces of the transport bucket 3 are rotatably connected with two groups of upper and lower positioning rollers 33.

[0034] Specifically, the engineering vehicle pours the concrete into the feed hopper 11, and then the concrete slides through the feed hopper 11 to the inside of the feed port 31, and is then stored in the transport bucket 3. Then the output end of the equipment motor 16 drives the drive shaft 13 to rotate, and the drive shaft 13 drives the two sets of winches 14 to rotate clockwise, loosening the transmission steel cable 15. At this time, the transport bucket 3 slides downward under the action of gravity.

[0035] In addition, a gate valve is provided at the lower end of the discharge pipe 32. After the transport bucket 3 is transported to the interior of the dam, the gate valve at the lower end of the discharge pipe 32 is opened to pour concrete into the interior of the dam to cast the interior of the dam. After the concrete is discharged, the output end of the equipment motor 16 drives the drive shaft 13 and the winch 14 to rotate counterclockwise, and the transmission steel cable 15 is wound up, thereby lifting the transport bucket 3 upward. After lifting it to the top, the material is loaded and transported again. At the same time, multiple sets of transport mechanisms can be used to cooperate to further improve the transport efficiency.

[0036] See Figure 2 、 Figure 3 and Figure 5 The positioning grooves 21 are respectively opened on the front and rear side surfaces of the two groups of positioning rods 2, and multiple groups of positioning rollers 33 are respectively slidably connected to the positioning grooves 21 on the same side. The sides of the two groups of positioning rods 2 are fixedly connected with mounting rods 22, and the rear ends of the mounting rods 22 are fixedly connected with mounting plates 23. Two groups of fixed anchor rods 24 are inserted into the surface of the mounting plates 23. The fixed anchor rods 24 are fixed inside the mountain. The upper surface of the upper mounting rod 22 is fixedly connected to multiple groups of support rods 25, and the upper ends of the support rods 25 are fixedly connected to the lower surface of the unloading platform 1.

[0037] At the same time, during the lifting process of the transport bucket 3 , the positioning roller 33 slides inside the positioning groove 21 to position the transport bucket 3 , thereby improving the stability of the transport bucket 3 during transportation.

[0038] The working principle of the utility model is as follows: the concrete is transported to the surface of the unloading platform 1 by an engineering vehicle, and then the concrete is poured into the interior of the transport bucket 3. At this time, the feeding mechanism transports the transport bucket 3 vertically downward along the steep slope, reducing the conveying distance, making it easier to quickly transport the concrete to the interior of the dam, and improving the transportation and pouring efficiency of the dam.
