DETAILED DESCRIPTION

[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-5As shown, an admixture delivery device comprises a working box 1, the upper and lower ends of the working box 1 are open, a screen 2 is arranged at the lower end opening of the working box 1, a vibration motor 3 is arranged on the outer surface of the working box 1, a funnel 4 for receiving the material in the working box 1 is arranged at the lower end of the working box 1, supporting legs 5 are evenly arranged on the lower surface of the funnel 4, the lower end of the funnel 4 is open, a pumping device 6 is arranged on the outer surface of the working box 1, a feed pipe 7 and a discharge pipe 8 are arranged on the pumping device 6, and an end of the feed pipe 7 away from the pumping device 6 is connected to the funnel 4 The lower end of the working box 1 is connected through, a horizontal plate 9 is provided at the upper opening of the working box 1, and the working box 1 also includes a fixing rod 10. The lower end of the fixing rod 10 is provided with a cover 11 for closing the lower opening of the funnel 4. The upper end of the fixing rod 10 passes through the screen 2 and the horizontal plate 9 in turn and is connected with the stopper 12. A rotatable bolt 13 is provided on the stopper 12. The bolt 13 is connected to the horizontal plate 9 by a thread. A spring 14 is provided on the fixing rod 10 and located inside the funnel 4. When the cover 11 closes the lower opening of the funnel 4, the spring 14 is in a compressed state.

[0020] The working box 1 and the screen 2 are both made of metal. The screen 2 is fixed to the lower end surface of the working box 1 by welding or threaded connection. The screen 2 is made of fine steel wire in a grid shape. Under the continuous vibration of the vibration motor 3, the agglomerated admixture is continuously collided with the screen 2, thereby breaking and breaking up the agglomerated admixture. When the admixture passes through the mesh, the admixture passing through the mesh part can be sucked into the interior of the pumping device 6 through the feed pipe 7 by the pumping device 6, and discharged into the mixer through the discharge pipe 8. The discharge pipe 8 is a foldable and stretchable folding pipe made of rubber or plastic. The length of the discharge pipe 8 can be changed to improve the convenience of controlling the delivery of the admixture.

[0021] When the pumping device 6 is not in a working state, part of the admixture in the working box 1 is not in a lumpy state, and more admixture can directly pass through the screen 2 into the funnel 4 and gather at the bottom of the funnel 4, which can easily cause blockage of the inlet of the feed pipe 7, thereby affecting the normal use of the pumping device 6. Therefore, the cover 11 is set to prevent the inlet of the feed pipe 7 from being blocked, thereby ensuring that the pumping device 6 can be used normally.

[0022] The spring 14 is in a conical spiral shape as a whole. When the cover 11 closes the lower end opening of the funnel 4, the spring 14 is in a compressed state, and the bolt 13 is rotated and fixed on the cross plate 9. At this time, admixtures can be put into the working box 1, and the admixtures put in will not enter the feed pipe 7. When the vibration motor 3 and the pumping device 6 are started, the bolt 13 is removed from the cross plate 9. Under the action of the spring 14, the fixing rod 10 and the cover 11 are pushed upward. At this time, the admixture in the funnel 4 can enter the feed pipe 7 normally, and under the action of the pumping device 6, it is transported to the mixer through the discharge pipe 8. After the admixture in the working box 1 passes through the screen 2, due to the obstruction of the spring 14 and the cover 11, a large amount of admixture can be prevented from entering the feed pipe 7 in a short time, thereby causing blockage of the feed pipe 7, and the vibration motor 3 transmits vibration to the spring 14, and the spring 14 can evenly spread the admixture downward.

[0023] Working principle: First, fix the block 12 on the cross plate 9 by the bolts 13 to ensure that the cover 11 can complete the closure of the lower end opening of the funnel 4, and then put a certain amount of admixture into the working box 1, then start the pumping device 6 and the vibration motor 3, and then unscrew the bolt 13 from the cross plate 9, and push the fixing rod 10 and the cover 11 upward under the action of the spring 14. At this time, the admixture in the funnel 4 enters the material taking pipe through the lower end opening of the funnel 4, and is transported to the mixer through the pumping device 6 and the discharge pipe 8 to realize the delivery of the admixture. The cooperation of the vibration motor 3 and the screen 2 can break up the agglomerated admixture and improve the quality of the concrete.

[0024] Furthermore, the inner surface of the funnel 4 is provided with a stepped groove 15, which has a side surface and a bottom surface. The side surface of the stepped groove 15 is perpendicular to the screen 2, and the bottom surface of the stepped groove 15 is inclined downward. The stepped groove 15 can increase the ability of the side of the funnel 4 to receive the admixture, prevent a large amount of admixture from quickly accumulating at the bottom of the funnel 4, and under the action of the vibration motor 3, the admixture located on the inner side of the funnel 4 is prompted to gradually move downward, ensuring that the admixture can enter the feed pipe 7 more smoothly, and preventing the feed pipe 7 from being blocked.

[0025] Furthermore, cover plates 16 are hinged on both sides of the transverse plate 9, and one side of the cover plate 16 is connected to the outer surface of the working box 1 through a locking member 17. The cover plate 16 can reduce the spillage of dust when the admixture vibrates, and the locking member 17 can keep the cover plate 16 and the working box 1 stably connected for a long time.

[0026] Furthermore, the lower end surface of the support leg 5 is provided with a moving wheel 18, which facilitates the movement of the device and improves the convenience of using the device.

[0027] Furthermore, a compressible docking port 19 is provided at the lower end of the cover shell 11 . The docking port 19 is made of rubber. The ability of the cover shell 11 to close the lower end opening of the funnel 4 can be further improved through the docking port 19 .

[0028] The device can break up the lumps in the admixture through the vibrating motor 3 and the screen 2, and then as the admixture continues to fall, the admixture is quickly and timely transported to the mixer through the pump suction device 6, the feed pipe 7 and the discharge pipe 8, thereby saving time and improving the dispersion degree of the admixture in the mixer and improving the mixing quality of the concrete.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
