Description
Technical field
The utility model relates to trucd mixer technical field, more particularly, relates to a kind of upset retaining mechanism of trucd mixer leakproof hopper.
Background technology
Agitator truck is the concrete special purpose vehicle of a kind of transportation, and its main structural components is mixing drum.Agitator truck is put into mixing drum the concrete mixing, and from mixing plant, is transported to site construction scene.Mixing drum is a kind of profile approximate ellipsoidal, and afterbody has the semiclosed cylindrical shell of feed inlet and outlet.Because mixing drum afterbody has opening, so in transportation, especially in agitator truck climbing process, occasional occurs that concrete is by the gush out phenomenon of mixing drum of feed inlet and outlet.The concrete of shedding out from mixing drum drops on road, can affect the road health in city.
In the prior art, conventionally on the long blowpit of agitator truck, install a leakproof hopper additional, can prevent the generation of above-mentioned phenomenon.If concrete is shed out in mixing drum in transportation, can wander in leakproof hopper, so just can not spill and fall to the ground.
Yet, wanting to bring into play the effect of leakproof hopper, the installation of leakproof hopper must have special connection retaining mechanism.This special mechanism must meet following requirement: 1, in vehicle transport process, leakproof hopper is fixed on long blowpit afterbody, plays the effect connecting material, and must be connected closely with long blowpit, can not because of travelling of vehicle, occur teetertottering.2, when agitator truck discharging, leakproof hopper can overturn, and does not affect discharging, and the leakproof hopper after upset still can be fixed.
In prior art, leakproof hopper both sides are drilled with pin-and-hole, and each couples together both sides leakproof hopper and long blowpit with a pin, and pin plays the effect that allows leakproof hopper overturn.A steady pin is respectively welded in the both sides of pin-and-hole, and two steady pins are respectively used to limit two positions of leakproof hopper.Use link plate to fix leakproof hopper, link plate one end is fixed on the handle of long blowpit, and the other end has a circular-arc draw-in groove.When leakproof hopper is when connecting material position, the draw-in groove of link plate is sticked in one of them pin.After the upset of leakproof hopper, the draw-in groove of link plate is sticked in another pin, by the draw-in groove of link plate and the relation that is mounted with of pin, fix leakproof hopper.
Yet, by the fixing leakproof hopper of the draw-in groove of link plate and the assembly relation of pin, this kind of fixed form is insecure, and in Vehicle Driving Cycle process, leakproof hopper can teetertotter, under extreme case, even occur that steady pin departs from the phenomenon of link plate draw-in groove, has a strong impact on the leakproofness of leakproof hopper.
Therefore, the steady pin of how avoiding leakproof hopper in Vehicle Driving Cycle process to teetertotter causing departs from the problem of link plate draw-in groove, improves the leakproofness of leakproof hopper, becomes those skilled in the art's technical problem urgently to be resolved hurrily.
