[0002] With the development of economy and society, various high-rise buildings have sprung up. The construction of high-rise buildings is inseparable from cement. Developing bulk cement is a major technical and economic measure to promote cement production and achieve increased production and savings. It is also a major reform in cement supply, transportation, storage and use. The cement bulk loader is a special equipment for bulk cement. It connects the cement silo with the cement bulk transportation tool and realizes the automatic or semi-automatic delivery of bulk cement through a series of interlocking actions of control devices.

[0003] During the cement assembly process, after the vehicle to be assembled stops stably, the relevant operators place the assembly pipe well and then carry out the assembly. To avoid waste of resources caused by too much or too little cement assembly, workers need to observe the assembly amount of cement at the filling port at all times and adjust the assembly amount at the same time. However, adjusting the cement filling amount by manual observation not only has a delay problem, but also has low accuracy and is prone to misjudgment, resulting in the situation that the filling stops too early and needs to continue filling or stops too late and needs to take out the excess cement, which affects the efficiency of cement assembly.

[0030] The PLC controller 13, the PLC controller 13 is used to control the servo motor 41 and the telescopic assembly 3.

[0031] Please refer to Figure 5 , symmetrically installed on the lower end face of the elastic plate 452 are downwardly protruding contact platforms 4521. The symmetrically arranged contact platforms 4521 correspond to the positions of the pressure sensors 453. The pressure sensors 453 cooperate with the contact platforms 4521. Specifically, the protruding contact platforms 4521 can trigger the pressure sensors 453 more stably, thereby avoiding incomplete force on the pressure sensors 453.

[0032] Please refer to Figures 1 - 2 , the upper end face of the material guiding box 1 is installed with a feeding hopper 11 communicated with the material guiding box 1. The assembly pipe 2 includes a fixed pipe 21 and a telescopic telescopic pipe 22. The lower end of the material guiding box 1 is installed with a connecting groove 14. The fixed pipe 21 is installed at the lower end of the connecting groove 14 and communicated with the connecting groove 14 through a connecting port 141. The lower end of the telescopic pipe 22 is installed with a filling nozzle 23. The side end of the material guiding box 1 is installed with a first dust removal pipe 12. The side end of the fixed pipe 21 is installed with a second dust removal pipe 24. Both the first dust removal pipe 12 and the second dust removal pipe 24 are provided with flanges for connecting with the dust removal equipment pipeline; Specifically, in this embodiment, during the falling process of the cement during quantitative pouring in the material guiding box 1 and the assembly pipe 2, the first dust removal pipe 12 and the second dust removal pipe 24 are connected to the dust removal equipment to absorb and process the dust generated at the above positions.

[0033] Please refer to Figure 2 , the upper groove surface of the connecting groove 14 is arc-shaped and the slope decreases from the outside to the direction of the connecting port 141. Please refer to Figure 3, the upper opening of the feeding port 43 is larger than the opening at the connection between the bottom and the rotating bin 44. Specifically, in this embodiment, the groove surface of the connecting groove 14 is arranged such that the cement coming out of the batching box 42 can stably enter the assembly pipe 2 for assembly, and the feeding port 43 can stably introduce the cement entering the material guiding box 1 into the rotating bin 44 without leakage. Embodiment 2

[0034] Based on the above Embodiment 1, please refer to Figure 1 and Figure 6 , the telescopic assembly 3 includes telescopic cylinders 31 fixed at the lower end of the connecting groove 14 and symmetrically arranged. The output end of the telescopic cylinder 31 is equipped with a telescopic rod 32. An actuating table 33 is installed on the outer wall of the upper end of the injection nozzle 23. The end of the telescopic rod 32 is fixedly connected to the actuating table 33. The servo motor 41, the pressure sensor 453, and the telescopic cylinder 31 are all electrically connected to the PLC controller 13.

[0035] In this embodiment, the PLC controller 13 can receive the signal of the pressure sensor 453 and set its trigger threshold to set the amount of assembled cement. At the same time, it can also control the servo motor 41 and the telescopic cylinder 31 to perform the assembly operation.

[0036] The working principle and usage process of the present utility model: When the transport vehicle stops at the assembly location and the assembly port of the vehicle is aligned with the position of the injection nozzle 23, after manual inspection is correct, the telescopic cylinder 31 can be started through the PLC controller 13. The telescopic cylinder 31 drives the telescopic rod 32 to push downward. The telescopic rod 32 drives the injection nozzle 23 to move downward through the actuating table 33 and stretches the telescopic tube 22 until the injection nozzle 23 is inserted into the assembly port of the transport vehicle. At this time, the assembly of cement can begin. The cement enters the material guiding box 1 from the feed hopper and falls on the feeding port 43, and then the cement falls along the feeding port 43 into the receiving groove 451 of the meter 45. As the cement accumulates in the receiving groove 451, the pressure on the elastic plate 452 and the contact platform 4521 continuously increases. At the same time, the contact platform 4521 transmits the pressure to the pressure sensor 453. When the pressure reaches the threshold value (i.e., when the receiving groove 451 is about to be filled with cement), the servo motor 41 drives the meter 45 to rotate, turning another empty receiving groove 451 on the meter 45 upward to correspond to the feeding port 43 to continue receiving materials. Repeat the above process. When the receiving groove 451 filled with cement rotates downward to correspond to the discharging groove 46, the cement falls out and enters the assembly pipe 2 through the connecting groove 14, and then is injected into the transport vehicle through the injection nozzle 23. Based on the above steps, the cement can be continuously assembled, and the assembled amount is a multiple of a single receiving groove 451. Combining with the transport load of the transport vehicle, the assembly can be accurately measured.
