[0019] Embodiment 1: Figure 1 , Figure 2 , Figure 3 , Figure 4 The overall structure of a cement concrete pavement cement paving machine is shown, and the cement concrete pavement cement paving machine mainly includes four parts: a frame 1, a material distribution device, a vibration compaction device and a control system 3;

[0020] The frame 1 is the main frame of the whole equipment, which is welded with high-strength steel and has good stability and load-bearing capacity. The front end of the frame 1 is provided with a mounting seat for the material distribution device, and the rear end is provided with a mounting seat for the vibration compaction device, which is convenient for the installation and removal of various components. At the same time, a walking mechanism is provided under the frame, so that the equipment can be flexibly moved on the working surface;

[0021] The material distribution device includes a hopper 2, a material distribution drum 8 and a screw feeder 7. The hopper 2 is fixed to the front end of the frame 1 by a connecting piece and is used to store cement concrete mixture. The material distribution drum 8 is located below the hopper 2 and is driven to rotate by a motor to evenly spread the mixture on the road surface. The screw feeder 7 is arranged between the hopper 2 and the material distribution drum 8, and the mixture is continuously and stably conveyed to the material distribution drum 8 by a spiral blade 74. A plurality of baffle plates 84 are provided on the material distribution drum 8, and grooves are formed between the baffle plates 84. When the mixture in the groove is evenly accumulated to a certain extent, the second motor 81 controls the second rotating shaft 83 to rotate so as to spread the mixture on the ground, thereby ensuring the continuity and uniformity of the laying;

[0022] The vibrating compaction device includes a vibrating roller 6 and a compaction plate 5. The vibrating roller 6 is mounted at the rear end of the frame 1 through a bracket, and a vibrator 61 is provided inside the vibrating roller 6, which can generate high-frequency vibration during operation, so that the cement concrete mixture quickly reaches a predetermined density after paving. The compaction plate 5 is located behind the vibrating roller 6, and is driven by a hydraulic cylinder 51 to move up and down, further compacting the road surface after vibration, thereby improving the flatness and strength of the road surface;

[0023] The control system 3 is the core part of the whole equipment, which uses PLC programmable controller to realize automatic control. The control system monitors the operation status of the equipment and the pavement paving quality in real time through sensors, and automatically adjusts the material spreading speed, vibration frequency and compaction times according to the set parameters to ensure the efficiency and stability of the paving process. At the same time, the control system also has fault diagnosis and alarm functions, which can detect and handle equipment failures in time, and improve the reliability and service life of the equipment.
