[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] See also Figure 1 and Figure 2 The utility model provides a material level detection device in a silo, which includes a silo 1 with an opening to ensure that materials can be injected from the top of the silo 1. A certain amount of liquid 6 is injected into the interior of the silo 1. By injecting a certain amount of liquid 6, when a bulk material 7 is injected, the material enters the interior of the liquid 6, and the liquid level of the liquid 6 is increased, so that it is convenient to measure the position of the bulk material 7 inside the silo according to the pressure change value of the liquid 6; a detection tube 3 is fixedly arranged at the bottom of the silo 1, and the detection tube 3 is arranged across the silo 1, and both ends of the detection tube 3 are connected to the silo. They all extend to the outside of the silo 1 to ensure that the part of the detection tube 3 located inside the silo 1 can detect the bulk material 7. One end of the detection tube 3 is provided with a visual tube 5 for displaying the detection result of the detection tube 3. The liquid level inside the silo 1 is detected through the visual tube 5 to calculate the amount of bulk material 7; a detection component is fixed to the position where the detection tube 3 is located inside the silo 1. The detection tube 3 is used to detect the pressure change of the liquid 6 inside the silo 1 to ensure that the amount of fixed bulk material 7 inside the silo 1 can be further calculated through the value of the pressure change.
[0019] See also Figure 2 and Figure 3 Preferably, the detection component of the present invention includes a sheath 4 fixed to the outside of the detection tube 3 and a capsule 9 fixed to the detection tube 3 and embedded in the inside of the sheath 4. The interior of the capsule 9 is connected to the interior of the detection tube 3. The outside of the sheath 4 is provided with a plurality of balancing holes 41. The liquid 6 inside the silo 1 enters the interior of the sheath 4 through the balancing holes 41 of the sheath 4, and then the pressure of the liquid 6 acts on the capsule 9, compressing the pressurized fluid inside the capsule 9, thereby reflecting the pressure of the liquid 6 to the inside of the visual tube 5, thereby realizing the detection of the pressure of the liquid 6.
[0020] In addition, the interior of the detection tube 3 of the present invention is connected to the interior of the sight tube 5, and a pressurized fluid is provided inside the detection tube 3. An observation block 10 is provided at the top of the inner side of the sight tube 5. The flow of the pressurized fluid pushes the observation block 10 to move inside the sight tube 5. The change in the compression volume of the capsule 9 pushes the internal pressurized fluid to flow, thereby pushing the observation block 10 to move inside the sight tube 5. A thrust spring 11 is provided between the top of the inner side of the sight tube 5 and the observation block 10, and a sealing ring is provided between the outer wall of the observation block 10 and the inner wall of the sight tube 5 to ensure that the observation block 10 can slide inside the sight tube 5 and the pressurized fluid will not flow between the observation block 10 and the inner wall of the sight tube 5.
[0021] Better yet, the detection tube 3 of the present invention is provided with an adjusting bolt 2 at one end away from the sight tube 5, the end of the adjusting bolt 2 is in contact with the pressurized fluid, and the adjusting bolt 2 is rotated to adjust the pressure of the pressurized fluid to achieve the adjustment of the detection pressure. The two ends of the sheath 4 are fixed to the outside of the detection tube 3, and the top of the sight tube 5 is provided with an air vent, which ensures the normal sliding of the observation block 10 and prevents the observation block 10 from appearing.
[0022] In this embodiment, when in use, first, a certain amount of liquid 6 is injected into the interior of the silo 1 according to demand. At this time, the adjusting bolt 2 can be rotated to adjust the position of the adjusting bolt 2 inside the threaded hole 8, and the position of the observation block 10 inside the sight tube 5 is further adjusted. Then, solid block material 7 is gradually injected into the interior of the silo 1, and then the liquid level of the liquid 6 gradually rises after the injection of the block material 7. At this time, the capsule 9 on the detection tube 3 is subjected to increasing pressure, which drives the pressurized fluid to flow and drives the observation block 10 to move, thereby reflecting the pressure changes of the liquid 6 and the amount of the block material.
[0023] In summary, the present invention provides a material level detection device in a silo, comprising: a silo with an opening at the top, which ensures that materials can be injected from the top of the silo, and a certain amount of liquid is injected into the interior of the silo. By injecting a certain amount of liquid, when injecting bulk materials, the materials enter the interior of the liquid, and the liquid level of the liquid is raised, so that it is convenient to measure the position of the bulk materials inside the silo according to the pressure change value of the liquid; a detection tube fixedly arranged at the bottom of the silo, the detection tube is arranged across the silo, and both ends of the detection tube extend to the outside of the silo, ensuring that the part of the detection tube located inside the silo detects the bulk materials, and one end of the detection tube A visual tube is provided at the end for displaying the detection results of the detection tube, and the liquid level inside the silo is detected through the visual tube, so as to calculate the amount of bulk material; a detection component is fixedly arranged at the position where the detection tube is located inside the silo, and the detection tube is used to detect the pressure change of the liquid inside the silo, so as to ensure that the amount of fixed bulk material inside the silo can be further calculated through the value of the pressure change. In summary, the technical effect produced by the utility model is that a fixed amount of liquid material is set inside the silo, and then bulk material is injected into the interior of the silo, so as to detect the liquid level and amount of solid material through the pressure change of the liquid.
