[0001] The utility model relates to the technical field of sludge transfer vehicles, in particular to a material scraping device for a carriage of a sludge transfer vehicle. Background Art

[0002] During the production process, the sludge in the factory needs to be transported. Sludge transport vehicles are mostly used to transport sludge and other materials with high water content. The material requires high airtightness to ensure that odor, water, etc. cannot overflow. When these transported materials have poor fluidity, they are prone to stacking. Fig.11 As shown, the carriage cannot be fully loaded and the number of transfers is high. At the same time, since the materials contain odor and other reasons, personnel are unable to enter to assist in paving the materials, which can easily lead to safety hazards. Utility Model Content

[0010] A further improvement is that the bottom end of the second transmission chain on the same side is fixedly connected to the bottom of the scraper.

[0011] A further improvement is that travel guide rails are arranged on the front and rear walls of the carriage, and guide rail sliders adapted to the travel guide rails are arranged on the middle parts of the front and rear ends of the scraper.

[0012] A further improvement is that the left travel sensor and the right travel sensor are located within the length range of the travel guide rail.

[0041] The working principle of the utility model: when in use, materials are poured in from the feed port. Due to the poor fluidity of these materials, stacking will occur. At this time, the servo motor will first drive the scraper to move to the left to scrape the material to the left. When the scraper runs to the left stroke sensor, the left stroke sensor will send a signal to the controller, and the controller will stop the servo motor and the scraper will stop running. At this time, the time relay starts timing. After a period of time, when the set time is reached, the servo motor reverses and drives the scraper to move to the right, and the scraper scrapes the material to the right. When the scraper reaches the right stroke sensor, the right stroke sensor will send a signal to the controller, and the controller will stop the servo motor and the scraper will stop running. At this time, the time relay starts timing. After a period of time, when the set time is reached, the servo motor reverses and drives the scraper to move to the left. Repeated movements are performed to scrape the material. When the material is full, the full load sensor will sense it, the controller will stop the servo motor, and issue an alarm to remind the staff. The time relay can be set to set the scraping interval according to the material loading speed.
