Description

Technical Field

[0001] This utility model relates to the technical field of rotary paddle level gauges, specifically a rotary paddle level gauge suitable for feeding raw material silos. Background Technology

[0002] A rotary paddle level gauge is a common material level detection device, mainly composed of a motor, drive shaft, paddles, and detection circuitry. Its working principle is that the motor drives the paddles to rotate. When material accumulates to the paddle position, the paddles encounter resistance and stop rotating. The detection circuit senses this change and outputs a switching signal, thus detecting the material level. It features simple structure, convenient installation, high reliability, and strong adaptability. It can be used to detect the level of various materials such as powders, granules, and lumps, and is widely used in material level control and alarm functions for silos and hoppers in industries such as chemical, grain, metallurgy, and building materials.

[0003] Existing rotary paddle level gauges have significant drawbacks in raw material silo loading scenarios: they are inconvenient to install and disassemble, traditional fixed structures require tools for assembly and disassembly, and the working space inside the silo is small, resulting in low maintenance efficiency; they also have poor shock resistance, as material impact and equipment vibration during raw material silo loading can easily cause the level gauge to loosen, affecting detection accuracy or even causing it to fall off. Utility Model Content

[0028] The mounting mechanism 1 includes a positioning component 11 and a mounting bracket component 12. The positioning component 11 is located on the right side of the material level device body 4, and the mounting bracket component 12 is located outside the positioning component 11.

[0029] The positioning assembly 11 includes a sleeve 1101, which is fixedly connected to the right side of the material level device body 4. The sleeve 1101 is rotatably connected to the outer ring of the rotating shaft 5. The upper and lower sides of the sleeve 1101 are fixedly connected to the locking strips 1102. The sleeve 1101 and the locking strips 1102 are locked inside the hopper wall 3. The mounting assembly 12 includes a collar 1201, which is sleeved on the outer ring of the sleeve 1101.

The sleeve box 1202 is fixedly connected to the left side of the hopper wall 3. The front and rear sides of the collar 1201 are fixedly connected to the reinforcing fins 1203, which are fixedly connected to the left side of the hopper wall 3.

[0030] Furthermore: The material level device body 4 is snapped onto the left side of the material level device body 4 by the locking assembly 11 and the locking seat assembly 12. The separate design makes it easy for the staff to install and disassemble the material level device body 4, and the operation is simple and convenient for the staff to use.

[0031] Example 2

[0032] See Figure 1 , Figure 3 , Figure 4 and Figure 5 Furthermore, based on Embodiment 1, the locking mechanism 2 includes a positioning component 21, a self-locking component 22, and a disassembly component 23. The positioning component 21 is disposed on the upper and lower sides of the card holder component 12, the self-locking component 22 is disposed on the upper and lower sides of the card holder component 12, and the disassembly component 23 is disposed on the outer side of the self-locking component 22.

[0033] Positioning component 21 includes a panel 2101, which is snapped into the front side of the housing 1202. A retaining plate 2102 is fixedly connected to the rear side of the panel 2101, and the retaining plate 2102 is snapped into the retaining strip 1102 and the housing 1202. A fixing arm 2103 is fixedly connected to the front side of the panel 2101, and a handle 2104 is fixedly connected to the front side of the fixing arm 2103. Self-locking component 22 includes a fixing box 2201, which is fixedly connected to the upper and lower sides of the housing 1202. The fixing box 2201 slides inside the fixing box 2201. The slide plate 2202 is dynamically connected. A compression spring 2203 is fixedly connected to the outside of the slide plate 2202. A locking rod 2204 is fixedly connected to the inside of the slide plate 2202. The locking rod 2204 is engaged in the locking strip 1102, the sleeve box 1202 and the locking plate 2102. The disassembly assembly 23 includes a telescopic slide rod 2301. The telescopic slide rod 2301 is fixedly connected to the outside of the slide plate 2202 and slidably connected to the inside of the fixed box 2201. A pull rod 2302 is fixedly connected to the outside of the telescopic slide rod 2301.

[0034] Furthermore: After the card plate 2102 is engaged with the card strip 1102 and the housing 1202, the slide plate 2202 will drive the card rod 2204 to move inward under the action of the compression spring 2203, so that the card rod 2204 is engaged with the card strip 1102, the housing 1202 and the card plate 2102 to lock the three together, so that the card plate 2102 cannot detach from the connection between the card strip 1102 and the housing 1202, thus ensuring the stability of the material level device body 4 after installation.

[0035] In actual operation, when this device is in use and the material level sensor body 4 needs to be installed, the operator first moves the material level sensor body 4 to the left side of the hopper wall 3, aligning the sleeve 1101 and the locking strip 1102 with the collar 1201 and the housing 1202 respectively. Then, the operator moves the material level sensor body 4 to the right, so that the sleeve 1101 and the locking strip 1102 are respectively engaged in the collar 1201 and the housing 1202. After that, the operator can fix the lever 51 to the right end of the rotating shaft 5 on the right side of the hopper wall 3, i.e., inside the hopper. Then, the operator pulls the upper and lower levers 2302 outward. The pull lever 2302 moves outward through the telescopic slide rod 2301, which drives the slide plate 2202 outward. The outward movement of the slide plate 2202 drives the locking rod 2204 outward. Move outward and retract into the fixed box 2201. Then, the operator can attach one of the card plates 2102 to the card strip 1102 and the housing 1202 on one side of the card rod 2204 until the insert 2101 is attached to the front of the housing 1202. Then release the limit on the pull rod 2302 on that side. At this time, the slide plate 2202 will drive the card rod 2204 to move inward by itself under the action of the compression spring 2203. The card rod 2204 moves inward and passes through the housing 1202 to attach to the card strip 1102 and the card plate 2102. At this time, the locking of the card plate 2102 on that side is completed. Then, repeat the above operation to the card plate 2102 on the other side until the card plates 2102 on both the upper and lower sides are installed. At this time, the installation of the material level device body 4 is completed.
