Description

Technical Field

[0001] This utility model relates to the field of garbage truck technology, and in particular to an urban sanitation street garbage truck. Background Technology

[0002] Garbage trucks are used to collect household waste from city streets. Common garbage trucks are mainly divided into compactor type, wall-mounted type, and hook-lift type. Hook-lift garbage trucks are special vehicles designed specifically for collecting standardized garbage bins. Their core function is to automatically grab, empty, and reset the garbage bins through a hydraulic lifting mechanism. The hook-arm lifting system equipped at the rear of the truck can be adapted to various national standard garbage bins. During operation, a hydraulic cylinder drives a robotic arm to precisely grab the bin and lift it to the top of the truck to complete the emptying. The entire process requires no manual handling. Compared to compactor garbage trucks, hook-lift models are more suitable for decentralized garbage collection scenarios such as communities and commercial streets. A single cycle operation time can be controlled within 30 seconds, significantly improving collection efficiency.

[0003] Patent document CN202729061U discloses a tractor-mounted garbage truck with a hook-lift mechanism, including a tractor and a body. An automatic lifting device is connected to one side of the body. The automatic lifting device includes a support frame, a hook-lift frame, and paired guide rails. The upper end of the guide rails is arc-shaped. The upper end of the support frame is hinged to the middle of the hook-lift frame. The lower end of the support frame and the upper end of the hook-lift frame are respectively located within the guide rails. A hook is fixedly connected to the outer side of the hook-lift frame. The lower end of the guide rails is connected to a lower crossbeam, and the middle of the guide rails is connected to an upper crossbeam. A vertically arranged hydraulic cylinder is connected to the lower crossbeam. The telescopic end of the hydraulic cylinder is connected to a horizontally arranged roller seat. Rollers are connected to both ends of the roller seat, and chains mesh on each roller. One end of each chain is connected to the support frame, and the other end of each chain is connected to the upper crossbeam. This utility model has low investment costs, low maintenance rates, and is suitable for use in small and medium-sized towns and rural areas.

[0004] As in the prior art of the aforementioned patent, the hook-lift garbage truck, including most existing hook-lift garbage trucks, uses a tilting device to lift the garbage bins to the top of the truck and then tilts them, dumping the garbage through the feed inlet on the top of the truck. To prevent garbage from accumulating below the feed inlet and causing uneven distribution of garbage inside the truck, a hydraulic mechanism at the bottom of the truck is used to tilt and rotate the truck after each loading, thereby sliding the garbage to the rear of the truck and not affecting the loading of the next batch of garbage. However, relying solely on the weight of the garbage itself to make the garbage accumulated below the feed inlet slide to the rear of the truck, some garbage still cannot slide and accumulates.
