Two embodiments of the distribution device of the present application are first described below:

example one

As shown in fig. 1 to 3, the material distribution device of the present embodiment includes a feeding hopper 10, a discharging portion 20, and a discharging adjustment mechanism 30. Wherein, the upper hopper 10 is provided with a first inlet 11 and a first outlet 12, the blanking part 20 is connected below the upper hopper 10, the blanking part 20 is provided with a second inlet 21 and a second outlet 22, and the second inlet 21 is communicated with the first outlet 12. The discharging adjustment mechanism 30 is arranged on the discharging part 20, and the discharging adjustment mechanism 30 is suitable for adjusting the distance between the discharging point 40 of the distributing device and the second inlet 21 along the horizontal direction.

By using the technical scheme of the embodiment, the discharging adjusting mechanism 30 can adjust the distance between the discharging point 40 of the distributing device and the second inlet 21 along the horizontal direction, that is, the position of the discharging point 40 can be extended or shortened, so that the discharging range can be changed. The discharging adjusting mechanism 30 is matched with the movement of the material distributing device, so that the material distributing range can be adjusted more flexibly, and the efficiency and the material distributing quality of the material distributing process are improved. Therefore, the technical scheme of the embodiment overcomes the defects that the distribution range of the distributing machine in the prior art is fixed and cannot be flexibly adjusted.

The upper hopper 10 has a hopper-shaped structure with a large upper part and a small lower part, and penetrates vertically. The upper end of the feeding hopper 10 forms a first inlet 11, the bottom end of the feeding hopper 10 forms a first outlet 12, and the stirred concrete is loaded into the distributing device through the first inlet 11.

It should be noted that the blanking portion 20 is substantially a tubular structure, and the second inlet 21 and the second outlet 22 are respectively disposed on two sides of the tubular structure. Wherein, the second inlet 21 opens upwards and is connected with the first outlet 12, and the second outlet 22 opens downwards, thereby realizing the downward distribution of the concrete. It can also be seen in connection with fig. 3 that a screw feed shaft is arranged in the blanking portion 20, which screw feed shaft can feed concrete from the second inlet 21 to the second outlet 22. Preferably, the central axis of the blanking portion 20 is perpendicular to the central axis of the upper hopper 10.

Further, a washing machine opening is formed in the top or the side of the blanking portion 20, and internal devices such as a spiral feeding shaft and the like can be conveniently washed.

As shown in fig. 3, in the solution of the present embodiment, the blanking portion 20 includes a first feeding pipe 23 and a second feeding pipe 24 which are nested with each other. The second inlet 21 is arranged on the first feeding pipe 23, the second outlet 22 is arranged on the second feeding pipe 24, the second feeding pipe 24 forms the outfeed adjustment mechanism 30, and the second outlet 22 forms the outfeed point 40. The material distribution device further comprises a first driving mechanism 50, and the first driving mechanism 50 drives the second feeding pipe 24 to extend and retract relative to the first feeding pipe 23. Specifically, the first feeding pipe 23 and the second feeding pipe 24 are coaxially arranged, the diameter of the first feeding pipe 23 is slightly larger than that of the second feeding pipe 24, and the first feeding pipe 23 is sleeved outside the second feeding pipe 24 (of course, the first feeding pipe 23 and the second feeding pipe 24 are also intentionally arranged to be sleeved outside the first feeding pipe 23). The second inlet 21 is arranged at the end of the first feeding tube 23 remote from the second feeding tube 24 and the second outlet 22 is arranged at the end of the second feeding tube 24 remote from the first feeding tube 23. Since in this embodiment the concrete is discharged directly from the second outlet 22 and falls onto the lower mould table, the second outlet 22 forms the discharge point 40 of the distribution device. As will be understood by those skilled in the art in conjunction with FIG. 3, the discharge point 40 becomes farther when the second feeding tube 24 is extended with respect to the first feeding tube 23, and the discharge point 40 becomes closer when the second feeding tube 24 is retracted with respect to the first feeding tube 23. When the first driving mechanism 50 drives the second feeding pipe 24 to extend or retract relative to the first feeding pipe 23, the material distribution range can be adjusted.

As shown in fig. 3, in the solution of the present embodiment, the first driving mechanism 50 includes a first driving cylinder, a first cylinder body 51 of the first driving cylinder is disposed on the first feeding pipe 23, and a first push rod 52 of the first driving cylinder is connected to the second feeding pipe 24. Specifically, the first push rod 52 is perpendicular to the central axis of the second feeding pipe 24, and when the first push rod 52 of the first driving cylinder extends or retracts, the second feeding pipe 24 can be controlled to extend or retract relative to the first feeding pipe 23. Of course, the first driving mechanism 50 may be other conventional linear driving mechanisms, such as a lead screw and nut mechanism, an electric push rod, etc.

As shown in fig. 3, in the solution of the present embodiment, the blanking portion 20 is rotatably connected below the upper hopper 10, and the material distributing device further includes a second driving mechanism 60, wherein the second driving mechanism 60 drives the blanking portion 20 to rotate relative to the upper hopper 10. Specifically, the second inlet 21 of the blanking portion 20 and the first outlet 12 of the feeding hopper 10 may be connected by an intermediate sliding structure to realize relative rotation therebetween, for example, the second inlet 21 and the first outlet 12 may be connected by a bearing. The second driving mechanism 60 may be a motor, the motor is connected to the blanking portion 20 through a gear mechanism, and the second driving mechanism 60 may also be another conventional rotation driving structure. When the blanking portion 20 rotates, the second outlet 22 can rotate in the circumferential direction around the second inlet 21, so that the position of the material obtaining point 40 can be adjusted in the circumferential direction, thereby expanding the distribution range. Meanwhile, the material point 40 can move in a more complex track by matching with the telescopic motion of the second feeding pipe 24, and the material point feeding device is particularly suitable for the material distribution process of special-shaped components. The feeding part 20 is rotatable with respect to the charging hopper 10, and the rotation may be performed in the entire circumferential direction or may be performed in a range of angles.

Further, the feeding hopper 10 is provided with a weighing device and a weight display device to display the weight of the remaining concrete material of the feeding hopper 10 in real time. The linear running speed of the material distribution, the rotating speed and the angular displacement of the blanking part 20 and the rotating speed of a spiral feeding shaft in the spiral conveyor are controlled in real time through the weight change, so that the effect of accurate discharging is realized.

Example two

As shown in fig. 4, the distributing device of the second embodiment is different from the first embodiment in that the discharging adjustment mechanism 30 includes a sloping feeding plate 31 disposed below the second outlet 22, a discharging point 40 is formed at a bottom end of the sloping feeding plate 31, and the first driving mechanism 50 is adapted to adjust a relative position of the sloping feeding plate 31 and the second outlet 22 in a horizontal direction. Specifically, in the second embodiment, the blanking portion 20 has a fixed cylindrical structure, and is not stretchable and contractible. The inclined feeding plate 31 is of an inclined plate-shaped structure and is arranged right below the second outlet 22, and one end of the inclined feeding plate 31 facing away from the upper hopper 10 is a downward inclined bottom end, so that when the concrete is discharged from the second outlet 22, the concrete can continuously slide along the inclined feeding plate 31 and is conveyed from the bottom end of the inclined feeding plate 31 to a lower die table. As will be appreciated by those skilled in the art, in the second embodiment, the concrete is actually discharged from the bottom end (i.e., the right end in fig. 4) of the inclined feed plate 31, so that for the distributing device, the bottom end of the inclined feed plate 31 is the discharge point 40 of the distributing device. The first driving mechanism 50 is adapted to adjust the relative position of the inclined feeding plate 31 and the second outlet 22 in the horizontal direction, and further, the first driving mechanism 50 can drive the inclined feeding plate 31 to move along the direction of the axis of the blanking portion 20. As will be understood by those skilled in the art with reference to fig. 4, when the inclined feeding plate 31 moves to the right, the discharging point 40 may be moved farther, and when the inclined feeding plate 31 moves to the left, the discharging point 40 may be moved closer,

as shown in fig. 4, in the present embodiment, the first driving mechanism 50 includes a first driving cylinder, a first cylinder body 51 of the first driving cylinder is disposed at a lower side of the blanking portion 20, and a first push rod 52 of the first driving cylinder is connected to the swash plate 31. Specifically, the extending direction of the first push rod 52 is parallel to the direction of the central axis of the blanking portion 20, so that when the first push rod 52 extends and retracts, the discharging point can be adjusted to be farther or closer.
