Detailed Description

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The feeding device shown in fig. 1 and 2 comprises a frame 1, a lifting arm 2 with a first end hinged to the frame 1, a telescopic mechanism 3 with two ends hinged to the frame 1 and the lifting arm 2 respectively, a connecting rod 4 with a middle part hinged to the frame 1 or the lifting arm 2, a feeding hopper 5 with the other end hinged to the lifting arm 2, a pull rod 6 with two ends hinged to the first end of the connecting rod 4 and the feeding hopper 5 respectively, and a second telescopic mechanism 7 with two ends connected to the other end of the connecting rod 4 and the frame 1 respectively. The lifting arm 2 and the connecting rod 4 are hinged with the frame 1 through the same hinge shaft. The connecting lines of the hinged point of the lifting arm 2 and the connecting rod 4, the hinged point of the connecting rod 4 and the pull rod 6, the hinged point of the pull rod 6 and the feeding hopper 5, and the hinged point of the feeding hopper 5 and the lifting arm 2 are connected in turn to form a parallelogram.

As shown in fig. 5, the concrete mixer 8 is arranged on the concrete mixing boom pump truck, a front side plate 10 and a rear side plate 11 of a feed hopper 9 of the concrete mixer 8 are hinged with the feed hopper 9, and when the boom of the boom pump truck is folded, the front side plate 10 and the rear side plate 11 can be both flatly placed, so that the boom is placed on the mixer, and the transition transportation is facilitated.

The working principle is as follows: the hinge points of the lifting arm 2, the connecting rod 4, the pull rod 6 and the feeding hopper 5 which are connected with each other form a parallelogram. When the lifting arm 2 rotates, the horizontal angle of the feeding hopper can be ensured to be unchanged, and the feeding hopper can not be overturned to be stably lifted. The second telescopic mechanism 7 realizes the overturning action of the feeding hopper 5 by changing the shape of the parallelogram. When the arm support of the concrete mixing arm support pump truck is folded, the arm support needs to be placed on the concrete mixer 8. The front side plate 10 and the rear side plate 11 of the feed hopper 9 are hinged with the feed hopper 9 and can be laid flat to avoid interference with an arm support.

The loading state as shown in fig. 1: the telescopic mechanism 3 is contracted to the minimum stroke, the second telescopic mechanism 7 is extended to the maximum stroke, and the feeding hopper 5 is positioned at the position closest to the ground at the moment, so that the feeding is facilitated. The lifting state shown in fig. 3: the telescopic mechanism 3 gradually extends to the maximum stroke, the second telescopic mechanism 7 keeps the position of the maximum stroke of the extension unchanged, and at the moment, the feeding hopper 5 is lifted to the highest position along with the extension of the telescopic mechanism 3. The discharge state shown in fig. 4: the second telescopic mechanism 7 keeps extending to the maximum stroke, the second telescopic mechanism gradually shrinks to the minimum stroke, at the moment, the feeding hopper 5 overturns along with the shrinkage of the second telescopic mechanism, and sand and stone and the like in the feeding hopper 5 are discharged into the concrete mixer 8.

Compared with the traditional manual mode, the technical scheme provided by the utility model can reduce the labor intensity and improve the efficiency. The concrete stirring and pumping device is convenient to use on concrete moving stirring and pumping equipment, and the front side plate 10 and the rear side plate 11 of the feed hopper 9 are hinged with the feed hopper 9 and can be laid flat to avoid interference with an arm support.
