Description

Technical Field

[0001] The invention belongs to the technical field of vehicles, and in particular relates to a self-unloading garbage truck with a garbage bin having a sliding door structure. Background Art

[0002] Garbage trucks are mainly used for municipal sanitation and large factories and mines to transport various types of garbage, especially for transporting residential garbage. The birth and development of garbage trucks is a major invention and creation for human society, especially for cities. The urban population is concentrated, and the amount of garbage generated every day is very large, while the urban land is limited, and the timely disposal of garbage is a major problem. The emergence of garbage trucks can help sanitation workers clean up garbage in time, and it is possible to turn garbage into treasure on the spot, which greatly reduces the work intensity of sanitation workers and alleviates the problem of urban garbage. The development of garbage trucks can not only solve the problem of urban garbage and relieve the pressure of sanitation workers. The birth of garbage trucks is also the birth of a new industry, which has driven the development of surrounding industries, increased people's employment opportunities, alleviated social employment pressure, and ultimately achieved a goal of promoting economic development. At present, the most commonly used type is the dump truck, which is used to collect, transfer, clean and transport garbage. Its main features are simple, efficient and environmentally friendly garbage collection methods, high vehicle utilization efficiency, and it is widely used in sanitation, municipal administration, factories and mines, property communities, residential areas with a lot of garbage and concentrated garbage, and urban street garbage disposal. It has a self-unloading function and hydraulic operation, which makes it easy to dump garbage. The working principle of the dump truck is the same as that of the dump truck, that is, the box can be unloaded, just like a dump truck and a dump truck. When loading garbage, people need to use tools to load the garbage, and unloading garbage means that the vehicle hydraulic top is raised and the garbage is directly poured out from the rear of the box. At present, the side doors of the garbage bins of the dump trucks with garbage collection functions are mostly opened upwards, and the side doors have a small opening angle, which affects the garbage delivery; the side doors have a large opening angle, which is convenient for garbage delivery, but due to the high opening height, the opening and closing operations are inconvenient, resulting in the vehicle being in the open state during the garbage collection process, resulting in the box not being closed, the garbage exposed, and the garbage smell also overflowing and affecting the environment. Summary of the invention

[0003] In order to overcome the above shortcomings, the present invention provides a dump truck with a garbage bin having a sliding door structure, which not only meets the requirement of a large side door opening, but also avoids the inconvenience of operating the side door due to its high opening height. It is also easy to operate and close, thus ensuring the sealing of the garbage bin.

[0005] Further optimization is that the auxiliary beam is installed on the automobile chassis, the box body is hinged to the auxiliary beam through a tilting axis, a lifting cylinder is installed between the auxiliary beam and the box body, and the hydraulic valve is installed at the rear of the automobile chassis cab and is connected to the hydraulic oil pump and the lifting cylinder through hydraulic pipelines.

[0006] Further optimization, the upper pulley is installed in the upper slide seat, the lower slider is installed in the lower slide seat, and the upper pulley and the lower slider slide left and right in the upper slide and the lower slide respectively.

[0007] Further optimization, the upper slideway and the lower slideway are installed in parallel at the upper and lower ends of the box body, and are used for the sliding of the left door and the right door.

[0008] Further optimization, the upper pulley and the lower slider are both made of wear-resistant materials.

[0009] For further optimization, a rear door is also installed on the box body, and a rear door lock is installed at the lower part of the rear door.

[0010] Further optimization is performed by installing side door locks on both the left door and the right door.

[0011] The beneficial effects of the present invention are: The present invention not only can open any side door according to the position requirement by staggering the front and rear positions of the left door and the right door, but also can avoid garbage overflow caused by opening two side doors on the same side at the same time. Especially when a large amount of garbage is loaded, the push-pull opening and closing are performed by the pulley, which can meet the requirements of a large garbage bin opening and convenient feeding, as well as a low operating height and light operation, thereby ensuring the sealing of the garbage bin during vehicle transportation.
