Abstract

The utility model discloses a truck hopper of the dump truck for transporting the concrete, comprising a bottom plate, side plates, an end plate, and a roof plate. The bottom plate and the two side plates are in an arc shape in the longitudinal direction, and are connected with the end plate smoothly by a ball panel. The bottom plate and the side plates are connected with each other by an arc panel, and the roof plate and the side plates are connected smoothly. The three-dimensional directions of the inner surface of the truck hopper are totally smooth curved faces, and the front and upper part of the truck hopper is provided with a feed inlet, while the tail part of the truck hopper is provided with a discharge opening and a hopper gate. As compared with the existing tipping vehicles, the utility model can effectively prevent the separation and the water bleeding of the concrete mixture, and is in particular suitable for transporting the flowability concrete and the non flowability concrete mixture on bad roads.

Description

Truck fank for transport concrete

The utility model relates to a kind of wagon box that is used to transport concrete dumping truck, in particular for the wagon box of the dumping truck of long-distance transport flowing power cement concrete on poor road or illiquidity concrete mix.

Setting up fixing concrete mixing plant, then the mixed concrete mixture is transported to each building soil respectively, is a developing direction of building field.But as carrying with common tip lorry, the inner structure of the vibration meeting disturbance mixture of automobile causes the segregation and the excreting water phenomenon of concrete mix, needs after mixture unloads to stir once again and could use.

Therefore, most countries and area adopt Mixer Truck to transport concrete mixture in the world at present, have prevented the segregation and the excreting water phenomenon of concrete mix effectively, but the cost height, economy is poor.

There is a kind of tip lorry that transports concrete mix in Sweden, its base plate shape is oval-shaped, interior band rubber back boxing, discharging opening is narrower, on more smooth road, transport concrete mix with this tip lorry, its segregation, bleeding degree are than common tip lorry much less, but when tip lorry travels on ups and downs poor road, top ripple along with vehicle, concrete mix is with collision repeatedly takes place between the side plate of railway carriage, harmful disturbance to the mixture inner structure is particularly violent, produces segregation and excreting water phenomenon thus.

The purpose of this utility model be to provide a kind of can eliminate effectively or reduce since automobile vibration to of the disturbance of concrete mix inner structure in all directions, thereby prevent that concrete mix from the wagon box of the dumping truck of segregation and excreting water phenomenon taking place.

The purpose of this utility model realizes in the following manner: all corner angle of promptly eliminating the wagon box inwall, whole wagon box inner wall surface is made level and smooth curved surface fully, contained concrete mix is no longer collided with sidewall, but along being subjected to force direction to be whole slippage on inwall, the inner structure of mixture is relatively stable, is not subjected to violent disturbance.

Specifically, wagon box of the present utility model comprises base plate, side plate, end plate and top board, base plate and biside plate vertically are being circular-arc And by spherical plate and end plate smooth connection, base plate and side plate are connected to each other by the circular arc panel, half top board and the side plate smooth connection of opening wide, and wagon box inside face three-dimensional is smooth surface, the wagon box front upper place is provided with inlet point, and it is oval-shaped discharging opening and sluice gate that the wagon box afterbody is provided with cross-sectional plane.

Another solution of the present utility model is: the upper fixed at above-mentioned inlet point has flange, and packing seal and top cover are housed on the flange, and top cover is provided with inlet point, charging flap, deflation hole and vent cap, and sluice gate is provided with discharging opening and discharging flap.

The utility model is compared with existing tip lorry, can prevent effectively that wagon box sidewall and concrete mix from bumping, thereby avoid or alleviate greatly the segregation of concrete mix, excreting water phenomenon is specially adapted to transportation flowing power cement concrete or illiquidity concrete mix on poor road.As by second scheme, behind the installation accessory, can be used for shipping bulk cement and municipal sludge.This wagon box is compared with the self-unloading wagon box that has mixing device, and cost and cost of transportation significantly reduce, and economy is significantly improved.

Concrete structure of the present utility model is provided by drawings and Examples.
