Description of reference numerals
The rear end face 2 guide cylinders of 1 mixing drum 11 mixing drums
3 feed hopper 31 delivery ends
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation that not doing contrary explanation, the noun of locality of use refers to inside and outside with respect to the profile of each parts itself as " inside and outside ", and " forward and backward " is undefined at the normal transport condition of concrete mixer truck.
As shown in Figure 1, according to an aspect of the present utility model, a kind of rabbling mechanism of concrete mixer truck is provided, comprise mixing drum 1, guide cylinder 2 and feed hopper 3, described guide cylinder 2 is arranged in described mixing drum 1, the delivery end 31 of described feed hopper 3 stretches into described guide cylinder 2 from outside, and wherein, the distance A between periphery wall and the internal perisporium of guide cylinder 2 of described delivery end 31 ends is 5mm-10mm.
In concrete mixer truck, guide cylinder 2 is with mixing drum 1 rotation, and feed hopper 3 is fixed on vehicle frame (not shown), in order to guarantee that guide cylinder 2 can rotate with respect to feed hopper 3, needs to exist gap between the two.In the utility model, by the distance A between the periphery wall of the delivery end of feed hopper 3 31 ends and the internal perisporium of guide cylinder 2 is set as to 5mm-10mm,, the size in the gap between the periphery wall of delivery end 31 ends and the internal perisporium of guide cylinder 2 is set as to 5mm-10mm, the amount of the concrete materials spilling from this gap is reduced relatively, reduced the flow velocity of concrete materials, reduced the amount of the concrete materials that flows to mixing drum 1 outside, save resource, reduced the pollution to environment.
For the structure of guide cylinder 2, preferably, described guide cylinder 2 can comprise the front portion 21 and the cylindrical circular rear portion 22 that are taper type, described anterior 21 and rear portion 22 be connected to form funnel-shaped structure, funnelform guide cylinder 2 can be guaranteed smooth charging.In this case, the distance A between periphery wall and the internal perisporium at described rear portion 22 of described delivery end 31 ends is 5mm-10mm.Guide cylinder 2 also can have other suitable structure arbitrarily, and for example can have cross section is square rear portion.At the rear portion of guide cylinder 2, be not in columnar situation, only the maximal clearance between need assurance guide cylinder 2 and delivery end 31 is between 5mm-10mm.
Preferably, described delivery end 31 also can be cylindrical, and coaxial with described guide cylinder 2, thereby can make the distance between the internal perisporium at rear portion 22 and the periphery wall of delivery end 31 ends of guide cylinder upwards consistent in whole week.Delivery end 31 can have other shape equally, and the utility model is not restricted delivery end 31 concrete shapes, as long as can make guide cylinder 2 rotate about it, and makes maximal clearance between delivery end 31 and guide cylinder 2 between 5mm-10mm.
Preferably, described delivery end 31 extends in described rear portion 22, is beneficial to the distribution of concrete materials.
In order to guarantee that guide cylinder 2 rotates together with mixing drum 1, preferably, described guide cylinder 2 is fixed in described mixing drum 1.
In order to distribute more equably concrete materials, preferably, described guide cylinder 2 is arranged in described mixing drum 1 coaxially.
According to one of the present utility model preferred embodiment, the distance B between the rear end face 221 of described guide cylinder 2 and the rear end face 11 of described mixing drum 1 is 20mm-100mm.As mentioned above, because concrete materials has certain flow rate, when concrete slump is larger, if guide cylinder outer face is 0～20mm apart from mixing drum end face, concrete can flow to mixing drum outside, therefore the distance B between the rear end face of guide cylinder 2 221 and the rear end face 11 of described mixing drum 1 is set as to 20mm-100mm, concrete materials from spilling between guide cylinder 2 and the delivery end 31 of feed hopper 3 can be flowed in mixing drum 1 along with the rotation of mixing drum 1, thereby can further reduce the amount of the concrete materials that flow to mixing drum 1 outside.
According on the other hand of the present utility model, a kind of concrete mixer truck is provided, this concrete mixer truck comprises the rabbling mechanism of the concrete mixer truck described in any one in above-mentioned embodiment.
The rabbling mechanism of concrete mixer truck of the present utility model does not increase material usage and processing cost, only, by adjusting mixing drum, guide cylinder and feed hopper three's relative position, can realize purpose of design.Concrete mixer truck of the present utility model is when going up a slope, and the amount of the concrete materials flowing out from the gap between guide cylinder and feed hopper will obviously reduce, and, even if there is material to flow out, its flow velocity is also relatively slow, therefore also can not go out mixing drum, but flow in mixing drum along blade.According in preferred embodiment of the present utility model, by increasing the distance between guide tube rear end face and mixing drum rear end face, thereby make concrete that the slump is larger also can not flow to the outside of mixing drum, increase the scope of application of the present utility model, further reduced the amount of the concrete materials of loss.The utility model has reduced the pollution to environment, has saved material and the energy, has increased economic benefit and social benefit.
Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present utility model, also can be combined, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
