Description

A grain transport vehicle with self-unloading function

technical field

The invention belongs to the field of grain transportation, in particular to a grain transportation vehicle with a self-unloading function.

Background technique

my country is a big consumer of grain and food, and it needs to transport hundreds of millions of tons of grain to all parts of the country every year. The existing grain transportation is mainly in the form of packaging. Since most of the packaging materials are made of poor-quality plastic woven bags, during the transportation, loading and unloading process, the situation of broken bags, loose grains, and throwing is more prominent, which not only increases labor costs, but also increases labor costs. The workload of loading and unloading and the difficulty of mechanical operations have led to rising loading and unloading costs, resulting in increasing grain logistics costs.

At present, although my country has carried out bulk grain transportation in the northeast region, some ports and newly-built grain logistics centers, the transportation vehicles used are generally cars with self-unloading functions or closed vans with unloading chutes. The above-mentioned vehicles are all special-purpose vehicles, and one vehicle is not used for multiple purposes, resulting in idle vehicles, low delivery rate, high logistics costs, and a certain waste of resources.

Vans with self-unloading function are generally rolled over, and there are multiple doors on the side of the cargo compartment, resulting in the need to constantly change the relative position of the conveyor belt device and the transport vehicle, resulting in a decrease in efficiency, and it is not suitable for a small loading and unloading site space. In order to improve the transportation efficiency, now more long-sized vans are used. When unloading grain, the hydraulic cylinder is lifted from the front. Instability, if the hydraulic cylinder has a small extension size, it cannot be unloaded cleanly. Moreover, this kind of jack-up type unloading grain can easily lead to the outflow of grain in the collapsed mode, and it is difficult to control the flow.

Due to the existence of the unloading chute, the closed van with unloading chute has deflector sloping plates and unloading ports at the bottom of the compartment, which is inconvenient for other cargo transportation, resulting in reduced vehicle transportation efficiency, and the multi-purpose of one vehicle cannot be realized.

Therefore, it has become an urgent problem to change the current situation of grain logistics, to explore and accelerate the development of new equipment for bulk grain transportation, to improve the efficiency of vehicle use, especially to realize multiple uses of one vehicle, and to achieve light weight.
