The elastic member 31 can provide an elastic force when the first alignment structure 32 contacts the second alignment structure 33, so as to prevent the transportation vehicle 1 from colliding with the base 5 and causing damage to the two. Base 5 can the snap-on in one side of pouring storehouse 10, and it should fully guarantee its fixed fastness when fixed, prevents to produce great skew when transport vechicle 1 laminates.
The rotary platform 6 is rotatably mounted on the base 5. The rotary platform 6 can be a circular platform which can rotate relative to the base 5, so that the structure on the rotary platform 6 can rotate relative to the pouring bin 10, and the position and the direction of feeding into the pouring bin 10 are changed, so that concrete can be poured in the pouring bin 10 uniformly.

The positioning column 8 penetrates through the lifting platform 9, and the threaded column 7 rotates to enable the lifting platform 9 to lift along the axial direction of the positioning column 8. Therefore, when the lifting platform 9 needs to be lifted, only the threaded column 7 needs to rotate, and the lifting platform 9 can only ascend or descend relative to the positioning column 8 under the limiting effect of the positioning column 8. The positioning column 8 can be integrally formed with the rotary platform 6, can also be welded on the rotary platform 6, and can also be installed on the rotary platform 6 through other structures.
The feeding mechanism comprises a feeding switch 11, a hopper 12, a driving shaft 13 and a driving piece 14, and also comprises a bearing 28, a first gear 29 and a second gear 30. A drive shaft 13 is rotatably mounted on the lifting platform 9 and is connected to the outer wall of the hopper 12. A drive member 14 is mounted on the lifting platform 9 and is adapted to rotate the drive shaft 13, causing the hopper 12 to rotate about the drive shaft 13. The feed switch 11 is mounted on the hopper 12 and is used to open or close the discharge opening of the hopper 12. In this embodiment, the bearing 28 is mounted on the lifting platform 9 with an axial direction parallel to the axial direction of the threaded stud 7.

When the discharge pipe 3 is not positioned above the hopper 12, the emitter and the receiver of the first photoelectric sensor 17 are staggered, so that the light signal emitted by the emitter cannot be received by the receiver, and the first photoelectric sensor 17 cannot generate a first switching signal. And the emitter and the receiver of the second photoelectric sensor 18 are respectively arranged on the hopper 12 and the storage pipe 15. When the feeding hole is positioned below the feeding hopper 12, the emitter of the second photoelectric sensor 18 is arranged opposite to the receiver thereof, and generates a second switch signal for driving the feeding switch 11 to be opened. Similarly, when the feed inlet is not located below the hopper 12, the transmitter and the receiver of the second photoelectric sensor 18 are staggered, and the second photoelectric sensor 18 does not send out the second switching signal.
The controller is used for driving the driving part 14 to rotate and driving the hopper 12 to rotate when the transport vehicle 1 and the base 5 are limited until the emitter of the first photoelectric sensor 17 is opposite to the receiver of the first photoelectric sensor. The controller is also used for driving the discharging switch 4 to be closed firstly after the discharging pipe 3 feeds a certain amount of concrete into the hopper 12, then driving the hopper 12 to rotate through the driving part 14 until the discharging pipe 3 is not positioned above the hopper 12, then driving the threaded column 7 to rotate through the driving mechanism until the lifting platform 9 rises to a certain height, driving the driving part 14 to rotate again and driving the hopper 12 to rotate until the emitter of the photoelectric sensor II 18 is arranged opposite to the receiver of the photoelectric sensor II, then driving the hopper 12 to rotate through the driving part 14 until the storage pipe 15 is not positioned below the hopper 12 after the concrete in the hopper 12 is all put into the storage pipe 15, and finally driving the threaded column 7 to rotate through the driving mechanism until the lifting platform 9 falls to a certain height, so that the emitter of the photoelectric sensor I17 is the same as the receiver of the photoelectric sensor I. The controller can control the related driving mechanism or the driving part 14 to work through the information detected by the detection mechanism, so that the material taking, the material transporting and the material feeding of the feeding device are completed, the whole process does not need manual intervention, the full-automatic operation of machinery is realized, and the warehousing efficiency of concrete can be improved.

After a certain amount of concrete is filled in the hopper 12, firstly, the controller can enable the discharging switch 4 to be closed to prevent the concrete from continuously falling from the discharging pipe 3, and then the controller starts the driving piece 14 to enable the hopper 12 to rotate around the driving shaft 13 until the discharging pipe 3 is not positioned above the hopper 12, so that the discharging pipe 3 is prevented from being impacted in the ascending process of the hopper 12. And then, the controller starts the driving mechanism, so that the threaded column 7 rotates to drive the lifting platform 9 to ascend under the limiting action of the positioning column 8 and stop ascending after ascending for a certain height, and then the controller drives the hopper 12 to rotate again until the hopper 12 is positioned above the storage pipe 15, at the moment, the emitter and the receiver of the second photoelectric sensor 18 are opposite and conducted, and then a second switching signal is sent. The second switch signal can drive the feeding switch 11 to be turned on, so that the concrete in the hopper 12 falls into the feeding hole from the discharging hole of the feeding switch 11, and is further fed into the pouring bin 10 from the discharging nozzles 16, and the feeding process of the concrete is completed. Finally, the controller orders about the driving piece 14 again to drive the hopper 12 to rotate after the concrete of the hopper 12 is put into the storage pipe 15, so that the storage pipe 15 is not located below the hopper 12, and then the controller rotates by ordering about the threaded column 7, so that the lifting platform 9 descends for a certain height, so that the hopper 12 receives the concrete discharged from the discharge pipe 3 again, and the feeding is performed in a circulating manner.
