The improvement of the technology lies in that the lower hopper 5 is arranged in several rows, each row of the lower hopper 5 corresponds to one spiral conveyor 6, that is, a plurality of spiral conveyors 6 are arranged, and since the lower hopper 5 is arranged in several rows, the space position above each lower hopper 5 is separated. After the space is separated, the steepness of the lower hopper 5 is increased, that is, the lower hopper 5 becomes steeper. In the steep lower hopper 5, the cement can be prevented from adhering to the inner wall by sliding. Embodiment

[0035] Different from the above embodiment, in the embodiment, the discharging mode of the technology is also improved. The main beam pipe 10 and the wing beam pipe 13 are arranged at the upper end of the bin body 2. The main beam pipe 10 and the wing beam pipe 13 not only have the effect of supporting the upper cover 3, but also have the effect of conveying cement and achieving uniform cement falling. Embodiment

[0036] The wing beam pipe 13 is arranged obliquely downward, the upper end is connected with the main beam pipe 10 and communicates with the main beam pipe 10, and the lower end is connected with the support 1.

[0037] Different from the above embodiment, in the embodiment, the wing beam pipe 13 is arranged obliquely, which facilitates uniform distribution of the cement in the wing beam pipe 13 and avoids accumulation of the cement into a conical shape. Embodiment

[0038] The bin body 2 is communicated with the lower hopper 5 at the bottom, the number of the lower hoppers 5 arranged above the spiral conveyor 6 is at least two, and the lower hoppers 5 are arranged side by side. The position where the lower hopper 5 contacts the bottom of the bin body 2 is divided into two ports, and the slope of the lower hopper 5 is increased.

[0039] Unlike the above embodiments, in this embodiment, the bottom of the hopper 2 is a support 1. The support 1 at the bottom of the hopper 2 is similar to a grid, with each grid corresponding to a hopper 5. Example

[0040] A feeding pipe 4 is provided on one side of the silo 2. The upper end of the feeding pipe 4 is connected to one end of the main beam pipe 10, and the other end of the main beam pipe 10 is closed.

[0041] Unlike the above embodiments, in this embodiment, the feeding pipe 4 is connected to an external pipe, and cement is pumped into the main beam pipe 10 by pressure. Example

[0042] The lower end of the wing beam tube 13 is closed.

[0043] Unlike the above embodiments, in this embodiment, the lower end of the wing beam tube 13 is in a closed state and is welded and fixed to the bracket 1. Example

[0049] Unlike the above embodiments, in this embodiment, an arch-breaking frame 17 is provided on the upper surface of the support frame 16. The arch-breaking frame 17 has an inverted triangular structure, with its lower end welded and fixed to the upper surface of the support frame 16, and the tip of the arch-breaking frame 17 facing upwards. By providing this arch-breaking frame 17, it is possible to further ensure that there is no cement residue in the silo 2.

[0050] The working method (or working principle) of this utility model:

[0051] In operation, this technology utilizes multiple rows of hoppers 5 at the lower end of the silo body 2, effectively dividing the single hopper 5 position found in existing technologies into two. Each row also contains an independent hopper 5, with each small hopper having a conical structure. This improvement increases the overall slope of the hoppers 5, preventing cement residue from remaining on the inner wall during discharging. Furthermore, the material feeding mechanism employs a combination of main beam pipe 10 and wing beam pipe 13 for more even cement distribution, preventing the formation of conical cement piles during the distribution process.

Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0053] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
