Description

Technical Field

[0001] This utility model relates to the field of septic tank truck technology, and in particular to a septic tank truck suction head. Background Art

[0002] Vacuum trucks are specialized vehicles primarily used for cleaning septic tanks, sewage ditches, and sewers. Along with water trucks and garbage trucks, they are considered one of the three major sanitation vehicle types. Vacuum trucks are no longer limited to public health; in animal husbandry, they are often used to remove manure from livestock habitats. During manure removal, a rectangular manure collection trough is dug near the livestock's living area to collect the manure, making it easier for the vacuum truck to suck it up. However, traditional vacuum trucks often struggle to completely remove manure from the trough walls, and the long-term accumulation of manure can breed pathogens, seriously impacting the health of livestock.

[0003] Existing technology CN206495311U discloses a suction head for a septic tank truck, including a suction pipe connected to the truck. The suction pipe has a guide cover at its end, with a rectangular opening. The two sides of the guide cover are fitted against the walls of the fecal collection trough. Scrapers driven by a motor are located on the inner sides of both sides of the guide cover. By adopting this technical solution, the scrapers first scrape off the softer feces from the trough walls by rotation, and then loosen some of the harder feces. The guide trough then scrapes off the loosened feces by compression, thus ensuring the cleanliness of the collection trough.

[0004] However, in the above technology, the scraper is installed on both sides of the guide cover by a motor to scrape the inner side of the tank wall. However, the scraper cannot move up and down, which limits the range of cleaning the collection tank and thus the cleanliness of the collection tank needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a suction head for a septic tank truck, which solves the problem in the prior art that the scraper cannot move up and down, thus limiting the cleaning range of the collection tank.

[0006] To achieve the above objectives, this utility model provides a suction head for a septic tank truck, comprising a suction pipe, a guide cover, and an electric scraper. The guide cover is located at the end of the suction pipe, and the electric scraper is located on the inner sides of both sides of the guide cover.

[0007] It also includes a scraper lifting device;

[0008] The scraper lifting device includes a connecting rod, a drive plate, a screw, a limit bearing, and a rotation drive assembly.

One side of the limit bearing is fixedly connected to the screw, and the other side of the limit bearing is fixedly connected to the guide cover. The limit bearing rotatably connects the screw and the guide cover. The rotation drive assembly is connected to the screw and drives the screw to rotate.

[0009] The rotation drive assembly includes a rotation motor, a fixed ring, and a mounting support member. The rotation output end of the rotation motor is fixedly connected to the screw, and the rotation motor is located at the upper end of the screw. The fixed ring is fixedly connected to the rotation motor and is sleeved on the outside of the rotation motor. The mounting support member is bolted to the fixed ring and is mounted on the outer wall of the guide cover.

[0010] The mounting support component includes a mounting ring and a mounting bracket. The mounting ring is fixedly connected to the mounting bracket and is located at the top of the mounting bracket. The mounting bracket is fixedly connected to the guide cover and is located on the upper outer wall of the guide cover.

[0011] The mounting ring has a plurality of threaded grooves, which are evenly spaced at the upper end of the mounting ring.

[0013] This utility model discloses a suction head for a septic tank truck. During suction, the suction head is placed into the septic tank. The truck is started, and the septic tank is guided through the guide cover and suction pipe into the tank. Simultaneously, two electric scrapers scrape off the softer septic tank walls and soften the harder septic tank. A rotating drive assembly drives a screw to rotate, which in turn moves a drive plate and two connecting rods up and down. This causes the electric scrapers to scrape the septic tank walls over a wider area, pushing the guide cover through the front teeth for cleaning. The scraper lifting device allows the electric scrapers at both ends of the guide cover to move up and down, increasing the cleaning area inside the septic tank and further improving its cleanliness.
