Description

Sieving device for freight vehicle hopper

Technical Field

The utility model belongs to the technical field of the equipment that sieves, concretely relates to a device that sieves for freight vehicle car hopper.

Background

With the development of cities, the pace of improving urban landscaping and landscape is also gradually accelerated. In the process of landscaping construction, a construction department needs to transport cultivation soil (namely planting soil) for seedling cultivation, and the cultivation soil is purchased from a supplier or solved by other ways. Because the cultivating soil is used for cultivating the nursery stock, the cultivating soil has certain standard requirements, the physical and chemical indexes are limited, the impurity content in the cultivating soil also has certain requirements, and particularly sand and stone are required to be screened out. Although the suppliers can carry out screening, the screening effect is not ideal, and the phenomenon that sand is used for imitating benefits is very common, so that the construction side is required to carry out screening and impurity removal again before the cultivation soil is constructed.

At present, in the concrete work progress, mostly transport the cultivation soil to the cultivation place through freight vehicle and topple over the back, by the manual work or with the help of engineering vehicle to carry out the screening, the mode of screening is comparatively laggard behind, carries out the operation through establishing the screen cloth promptly. Although the mode can screen sand to ensure the normal growth of the nursery stock in the later period, the operation mode is lagged behind and has slow efficiency; meanwhile, the screening process also needs a specially-assigned person to operate, and the cost is correspondingly improved.

In addition, the freight vehicle is covered with tarpaulin on the hopper in order to prevent material leakage during the operation process. However, in reality, workers are trouble-saving, the tarpaulin is very simple to bind, and the tarpaulin shakes due to air flow generated during the running of a vehicle, so that the leakage phenomenon is inevitable, and the tarpaulin wastes and pollutes the environment.

Therefore, how to design a screening device to be applied to freight vehicles, the screening can be carried out in the loading process, the inconvenience of subsequent screening can be greatly reduced, the construction cost can be reduced, the field screening certification and supervision can be carried out while the cultivated soil is loaded, and the reduction of the purchase price is obviously promoted.
