A multi-sensor integrated material level monitoring bin

Abstract

This utility model discloses a multi-sensor integrated material level monitoring bin, including a detection mechanism and a leveling mechanism. The detection mechanism includes a bin, two symmetrically arranged frames connected to the inner wall of the bin, and multiple material level sensors embedded in the inner side of the frames. The leveling mechanism includes two guide rods fixed inside the frames, a lifting plate slidably connected between the guide rods, and a scraper plate rotatably penetrating the bottom of the lifting plate. In this utility model, after material is added to the bin, the scraper plate is positioned on top of the material. Then, the movable end of the hydraulic cylinder extends and retracts at a set cycle, driving the toothed plate to rotate the gears, which in turn drives the scraper plate and the crossbars to rotate and level the material. When two material level sensors located on the same horizontal plane simultaneously detect the material signal, it indicates that the material surface has been leveled, thus ensuring the reliability of the detection results.

Description

Technical Field

[0001] This utility model relates to the field of material level monitoring bin technology, specifically a multi-sensor integrated material level monitoring bin. Background Technology

[0002] A material level monitoring bin is a specialized device or system used to detect and monitor the height or volume of materials within a storage container (such as a silo, tank, or hopper) in real time. Its core functions are to accurately determine material levels, prevent empty or overflowing bins, and enable automated replenishment or unloading control, thereby improving storage efficiency, ensuring production continuity, and operational safety. It is widely used in material storage and management in industries such as chemical, food, pharmaceutical, building materials, and energy.

[0003] In traditional material level monitoring silos, uneven material distribution (especially the tendency for localized areas to be higher than normal) often leads to inaccurate level readings. When material is discharged from the bottom of the silo, this localized accumulation of material is significantly aggravated, reducing the reliability of the monitoring data. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A multi-sensor integrated material level monitoring bin includes a detection mechanism and a leveling mechanism. The detection mechanism includes a bin, two symmetrically arranged frames connected to the inner wall of the bin, and multiple material level sensors embedded in the inner side of the frames. The leveling mechanism includes two guide rods fixed inside the frames, a lifting plate slidably connected between the multiple guide rods, a scraper plate rotatably passing through the bottom of the lifting plate, a gear attached to the top of the lifting plate and connected to the scraper plate, a toothed plate meshing with one side of the gear, a hydraulic cylinder connected between the lifting plate and the toothed plate, and multiple crossbars connected to the top of the hydraulic cylinder.

[0007] By adopting the above technical solution, after the material is put into the silo, the scraper is controlled to be placed on top of the material. Then, the moving end of the hydraulic cylinder extends and retracts according to the set cycle, driving the toothed plate to drive the gear to rotate, which in turn links the scraper and the crossbar to rotate and scrape the material. When two material level sensors located on the same horizontal plane detect the material signal at the same time, it indicates that the material surface has been flat, thus ensuring the reliability of the detection results.

[0008] In a preferred embodiment, this utility model can be further configured as follows: multiple level sensors are grouped in pairs, forming three groups, with the two level sensors in each group located on the same horizontal plane.

[0009] In a preferred embodiment, the present invention can be further configured such that: multiple corners of the lifting plate are rounded, and multiple guide rods are vertically coaxial with the centers of the multiple rounded corners.

[0010] In a preferred embodiment, the present invention can be further configured such that: multiple horizontal bars are equally spaced and arranged in a ring, and the scraper disc and the horizontal bars are both made of metal connected in series.

[0011] In a preferred embodiment, the present invention can be further configured such that: the lifting plate is provided with two sets of lifting components, each set of lifting components including a crossbar located on one side of the hopper and two pull ropes connecting the lifting plate and the crossbar.

[0012] In a preferred embodiment, the present invention can be further configured such that: two reinforcing ribs are sleeved on the outer side of the hydraulic cylinder body, and both reinforcing ribs are fixedly connected to the top of the lifting plate.

[0013] In a preferred embodiment, the present invention can be further configured such that: a guide plate is suspended at the top of the gear, the bottom of the guide plate is fixedly connected to the top of the lifting plate, and the diameter of the guide plate is equal to the diameter of the scraper plate.

[0014] In a preferred embodiment, the present invention can be further configured such that: two hooks are fixedly connected to both sides of the hopper, the distance between the two hooks is less than the length of the crossbar, and the hooks are suitable for engaging with the crossbar.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, after the material is put into the hopper, the scraper is controlled to be placed on top of the material. Then, the movable end of the hydraulic cylinder extends and retracts according to a set cycle, driving the toothed plate to drive the gear to rotate, thereby linking the scraper and the crossbar to rotate and scrape the material. When two material level sensors located on the same horizontal plane detect the material signal simultaneously, it indicates that the material surface has been flat, thus ensuring the reliability of the detection results.

[0017] 2. In this utility model, when feeding material into the hopper, the horizontal bar is pressed down to lift the entire lifting plate with the pull rope, and then the material is sprinkled down from the guide plate, which effectively avoids material from entering between the gears and the toothed plate, reducing the failure rate of this device.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0032] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0033] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a multi-sensor integrated material level monitoring bin.

[0034] Example 1:

[0035] Combination Figure 1-6 As shown, the present invention provides a multi-sensor integrated material level monitoring bin, including a detection mechanism 100 and a scraping mechanism 200. The detection mechanism 100 includes a bin 110, two frames 120 symmetrically arranged and connected to the inner wall of the bin 110, and a plurality of material level sensors 130 embedded in the inner side of the frames 120.

[0036] The leveling mechanism 200 includes two guide rods 210 fixed inside the frame 120, a lifting plate 220 slidably connected between the multiple guide rods 210, a scraper disc 230 rotatably passing through the bottom of the lifting plate 220, a gear 240 attached to the top of the lifting plate 220 and connected to the scraper disc 230, a toothed plate 250 meshing with one side of the gear 240, a hydraulic cylinder 260 connected between the lifting plate 220 and the toothed plate 250, and multiple crossbars 270 connected to the top of the hydraulic cylinder 260.

[0037] Furthermore, multiple level sensors 130 are arranged in pairs, forming three groups. In each group, the two level sensors 130 are located on the same horizontal plane. This arrangement of the level sensors 130 effectively improves the accuracy of material monitoring results.

[0038] Furthermore, the lifting plate 220 has rounded corners on multiple sides, and multiple guide rods 210 are vertically coaxial with the centers of multiple rounded corners. The layout design of the guide rods 210 makes the lifting plate 220 rise and fall more smoothly.

[0039] Furthermore, multiple horizontal bars 270 are evenly spaced and arranged in a ring. Both the scraper disc 230 and the horizontal bars 270 are made of metal connected in series. The layout design of the horizontal bars 270 can quickly scrape the material evenly.

[0040] Furthermore, a guide plate 500 is suspended on the top of the gear 240, and the bottom of the guide plate 500 is fixedly connected to the top of the lifting plate 220. The diameter of the guide plate 500 is equal to the diameter of the scraper plate 230. The guide plate 500 can prevent material from spilling between the gear 240 and the tooth plate 250, thereby reducing the failure rate of the device.

[0041] Example 2:

[0042] Combination Figure 1 and Figure 6 As shown, based on Embodiment 1, the lifting plate 220 is provided with two sets of lifting components 300. Each set of lifting components 300 includes a crossbar 310 located on one side of the hopper 110 and two pull ropes 320 connected between the lifting plate 220 and the crossbar 310. By pressing down the crossbar 310, the pull ropes 320 can be forcefully pulled to tighten the lifting plate 220, so that the lifting plate 220 as a whole is close to the top of the hopper 110, thereby facilitating the feeding of materials into the hopper 110.

[0043] Furthermore, two hooks 600 are fixed to both sides of the hopper 110. The distance between the two hooks 600 is less than the length of the crossbar 310. The hooks 600 are suitable for engaging with the crossbar 310. The hooks 600 can limit the crossbar 310, so that the lifting plate 220 can be lifted smoothly.

[0044] Example 3:

[0045] Combination Figure 3 and Figure 5 As shown in the above embodiment, two reinforcing ribs 400 are sleeved on the outer side of the cylinder body of the hydraulic cylinder 260. Both reinforcing ribs 400 are fixedly connected to the top of the lifting plate 220. The reinforcing ribs 400 can improve the installation firmness of the hydraulic cylinder 260.

[0046] The working principle and usage process of this utility model are as follows: In the initial state, the operator presses down the crossbar 310 and lifts the entire lifting plate 220 by pulling the rope 320. After the device is put into operation, the material is poured in from the top of the hopper 110. At the same time, multiple material level sensors 130 monitor the material height in the hopper 110 in real time. Then, the operator releases the crossbar 310, and the entire lifting plate 220 is placed on top of the material. Then, the movable end of the hydraulic cylinder 260 extends and retracts according to the set cycle, driving the toothed plate 250 to drive the gear 240 to rotate, which in turn links the scraper disc 230 and the crossbar 270 to rotate and scrape the material. When two material level sensors 130 located on the same horizontal plane detect the material signal simultaneously, it indicates that the material surface has been flattened, thus ensuring the reliability of the detection results.

[0047] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
