At the same time, it can also reduce the large amount of concrete dropping after the opening 17 is opened due to the accumulation of concrete, so as to facilitate the control of the concrete feeding amount. The sleeper mold box 22 can receive the dropped concrete, so that the concrete forms the required shape after solidification.

[0039] Refer to Figure 1 , the hopper 1 is erected on the ground through the mounting frame 23. The mounting frame 23 is two U-shaped frames. The hopper 1 is erected between the two U-shaped frames. Guide rails 24 are arranged between the mounting frame 23 and the ground. Two guide rails 24 are provided. A transport vehicle 25 is slidably arranged on each of the two guide rails 24.

A driving vehicle 27 is arranged between the placement rack 26 and the sleeper mold box 22. In this embodiment, the driving vehicle 27 is a vehicle body equipped with wheels and a motor. The sleeper mold box 22 is fixedly provided with a rotating shaft 28, and the sleeper mold box 22 is rotatably arranged on the driving vehicle 27 through the rotating shaft 28. The driving vehicle 27 slides along the length direction of the placement rack 26. Through the sliding of the driving vehicle 27 and the rotation of the sleeper mold box 22, the poured and solidified sleeper can be poured out of the sleeper mold box 22; a driving gear 29 is fixedly arranged on the rotating shaft 28, and a driving rack 30 is arranged at the end of the placement rack 26 in the length direction. The driving vehicle 27 drives the sleeper mold box 22 to slide, so that the driving gear 29 meshes with the driving rack 30. The driving rack 30 drives the sleeper mold box 22 to rotate. When the driving vehicle 27 slides to the end of the placement rack 26 in the length direction, the driving rack 30 cooperates with the driving gear to drive the sleeper mold box 22 to rotate 180 degrees, so that the opening 17 of the sleeper mold box 22 faces the ground, and the solidified sleeper is poured out of the sleeper mold box 22, which is convenient for the blanking of the sleeper; a vibrating gear ring 31 is fixedly arranged on the driving rack 30, and vibrating teeth 32 are arranged at the upper and lower sides of the driving gear 29 at a dislocation. The vibrating teeth 32 mesh with the driving gear 29. The sliding of the driving vehicle 27 drives the sleeper mold box 22 to swing through the vibrating teeth 32. Before the driving vehicle 27 drives the sleeper mold box 22 to slide to the driving rack 30, it will drive the sleeper mold box 22 to swing through the vibrating teeth 32 arranged at a dislocation with the vibrating gear ring 31, so that the solidified sleeper in the sleeper mold box 22 is loosened, which is convenient for the subsequent demoulding of the sleeper; a positioning block 33 is arranged on the mounting rack 23. The positioning block 33 is installed in the middle of the placement rack 26 and abuts against the bottom of the sleeper mold box 22 when the sleeper mold box 22 is directly below the opening 17, so as to limit the rotation of the sleeper mold box 22 on the driving vehicle 27, reduce the probability of the sleeper mold box 22 rotating due to the impact force when the concrete is blanked from the opening 17, and reduce the probability of the concrete falling outside the sleeper mold box 22 due to the rotation of the sleeper mold box 22 when the concrete is blanked.

[0042] The implementation principle of the embodiment of this application is as follows: The raw material conveying pipeline is arranged above the material box 42. Then, the elasticity of the elastic member 43 at the corresponding material box 42 is adjusted according to the proportion of the raw materials. After that, the raw materials are conveyed into the material box 42 through the raw material conveying pipeline. When the raw materials reach the preset weight, the raw materials drive the material box 42 to slide by their own gravity, so that the driving plate 62 abuts against the abutting plate 64. At this time, the baffle 5 at one end of the material box 42 facing the hopper 1 rotates to open the bottom of the material box 42, so that the required weight of raw materials falls from the material box 42 into the hopper 1. At the same time, the baffle 5 at the end of the material box 42 away from the hopper 1 rotates to close the top of the material box 42, and at the same time, the conveying of the raw material conveying pipeline is stopped to avoid the imbalance of the raw material proportion caused by the mixing of too many raw materials. The raw materials entering the hopper 1 are stirred and mixed by the rotation of the stirring blades 16. After the raw materials are stirred and mixed into concrete, the opening 17 is opened to discharge the concrete into the sleeper mold box 22 for the pouring of sleepers. The concrete is sequentially poured into all the sleeper mold boxes 22 arranged along the length direction of the guiding rail 24 through the conveying vehicle 25 conveying frame body to complete the pouring of the sleepers. After the sleepers are solidified and formed, the sleeper mold box 22 is driven by the driving vehicle 27 to slide towards the end of the placing rack 26 in the length direction. When the sleeper mold box 22 passes through the vibrating gear ring 31, it swings to loosen the sleepers. Then, when the sleeper mold box 22 passes through the driving rack 30, it rotates 180 degrees to demold the sleepers and drop them onto the conveyor belt 34. The sleepers are conveyed to the stacking and placing area through the conveyor belt 34 to complete the production of the sleepers.
