Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and it be as follows to coordinate accompanying drawing to describe in detail:
Referring to Fig. 1 and 2, the concreting hopper device of a kind of convenient construction, including bracing frame 1 and the bunker 2 being weldingly fixed in bracing frame of square frame-shaped.On four of bracing frame, corner location respectively installs a link, and the effect of link is: being easy to magazine attachment and be connected with lifting appliance by rope, whole magazine attachment is lifted to the construction location needing casting concrete, link is not shown in the accompanying drawings.Be provided with discharging opening 2-1 in the lower end of bunker, described discharging opening is obliquely installed, and namely the plane at discharging opening place is horizontal by certain angle.Two side positions being positioned at discharging opening upper end on bunker are respectively provided with a hinged seat 3 with hinge hole, and the hinge hole of two hinged seats is coaxially disposed.The door 4 being made up of monolithic steel plate it is provided with in discharging opening position, door keeps off on discharging opening, the upper end of door is fixed with jointed shaft 5, the two ends of jointed shaft are inserted in the hinge hole of two hinged seats respectively, make door form loose-leaf system with bunker to be connected, namely door can rotate in certain angular range around jointed shaft, so can realize the opening and closing of door.It is provided with in the outside of door and can realize the pulling-rod frame 6 that door opens and closes, described pulling-rod frame is made up of the two pull bar 6-1 be arrangeding in parallel and the cross bar 6-2 that is connected with two pull bar outer ends, the inner of two pull bars is fixing with jointed shaft to be connected, pulling-rod frame freely rides on the lower beam 1-1 of bracing frame, is provided with the adjustable compressing structure 7 that can be fixed on by pulling-rod frame in lower beam in the lower beam of bracing frame.Being under free-falling state at pulling-rod frame, described door is closed, and now, pulling-rod frame just freely rides in the lower beam of bracing frame.When pulling-rod frame is in and lifts, described door is in open mode, and now, the lower beam that pulling-rod frame is rotated up certain angle, pulling-rod frame and bracing frame around jointed shaft disengages.
In said structure, adjustable compressing structure is preferably: the adjusting nut 7-2 being connected with screw rod by the screw rod 7-1 in the lower beam being weldingly fixed on bracing frame and the L-type depression bar 7-3 being welded on adjusting nut lateral surface is constituted.Concrete, screw rod is fixed on the position in the inner side near a wherein pull bar or outside, when this pull bar of present dynasty rotates L-type depression bar, adjusting nut is gradually reduced along screw rod, also L-type depression bar is driven to synchronize to decline, when L-type depression bar rotate in place when the top position of this pull bar, the lower horizontal of L-type depression bar is just pressed on this pull bar, due to threaded, there is auto-lock function, so, it is achieved that being fixed whole pulling-rod frame, thus ensure that door is in the state of closing, when door is in and closes, can the concrete being stirred be injected in hopper, follow-up building is carried out after lifting by crane in order to magazine attachment.Otherwise, when needs unlatching door carries out concreting, only need to rotate backward L-type depression bar, L-type depression bar synchronizes to rise with adjusting nut in the process rotated, when L-type depression bar turns to the position completely disengaged from corresponding pull bar, being lifted up pulling-rod frame, pulling-rod frame drives jointed shaft to rotate, jointed shaft drives door to rotate, and makes door be gradually opened.This adjustable compressing structure has the advantage that locking is solid and reliable, and it is convenient and strength-saving to operate.
In said structure, the plane at discharging opening place of bunker and the angle of horizontal plane are preferably 30 °～45 °.Adopt this optimized angle to ensure that the smoothness of blanking on the one hand, also allow for the opening and closing of door on the other hand.
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of this utility model claim change and modify, and such as, adjustable compressing structure adopts the attachment structure etc. of common bolt and pressing plate, each falls within technical scope of the present utility model.
