Description

Technical Field

[0001] This utility model relates to the field of material shortage early warning technology for material storage boxes, specifically a material shortage early warning device for material storage boxes. Background Technology

[0002] In industrial production and warehousing logistics, material storage bins are widely used to store various solid or granular materials. However, real-time inventory monitoring of materials has always been a pain point in the industry. Traditional material inventory monitoring methods typically rely on periodic manual inspections or simple sensor detection, which suffer from inefficiency, insufficient accuracy, and the inability to provide real-time alerts. For example, manual inspections are prone to omissions or delays, while simple sensors may fail due to material characteristics (such as particle size and density) or environmental factors (such as dust and humidity). Therefore, developing a device that can accurately monitor material inventory and provide timely alerts is of significant practical importance. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a material shortage early warning device for a material storage box. The device includes a lead screw, a lead screw nut, a limit switch, and a movable plate. When real-time monitoring of the material in the storage box is required, employees do not need to manually inspect the storage box periodically. The drive motor rotates the lead screw, causing the limit switch, movable contact rod, and lower movable plate inside the housing to descend together. The lower movable plate presses against the material in the storage box, and the top of the movable contact rod presses against the limit switch contact. The limit switch then sends a signal, stopping the motor and indicating whether the material in the storage box has reached a pre-set warning threshold.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A material shortage early warning device for a material storage box includes a material storage box. A lead screw is vertically rotatably mounted on a support plate on the side of the material storage box. A lead screw nut is matched on the lead screw. A connecting plate on the side of the lead screw nut passes through a through groove and connects to an early warning triggering mechanism. The early warning triggering mechanism includes a housing. A limit switch is installed inside the housing. The contact of the limit switch faces a movable contact rod below. A lower movable plate for pressing the material in the material storage box is installed at the bottom of the movable contact rod. When the lead screw rotates, the lead screw nut drives the early warning triggering mechanism to move up and down in the vertical direction.

[0006] As a further improvement to the above solution, the movable contact rod passes vertically through the partition inside the housing, and a rod body is provided on the plate in the middle of the movable contact rod, with a first spring provided on the rod body.

[0007] As a further improvement to the above solution, a bearing is provided between the lead screw and the support plate, and the lower end of the lead screw is connected to the motor output shaft.

[0008] As a further improvement to the above solution, the insert block provided on the side of the connecting plate is matched with the locking block on the outer wall of the housing, and the insert block has a T-shaped block structure.

[0009] As a further improvement to the above solution, a baffle plate is provided in the through groove and below the connecting plate. The baffle plate is made of stainless steel in a folded plate shape.

[0010] As a further improvement to the above solution, a pushing mechanism is provided on the connecting plate. The pushing mechanism includes a connecting sleeve fitted on the connecting plate, a tube provided at the lower part of the connecting sleeve, a telescopic rod provided inside the tube, and a pushing plate provided at the bottom of the telescopic rod.

[0011] As a further improvement to the above solution, a second spring is provided inside the tube, and the pusher plate has an L-shaped plate structure.

[0012] As a further improvement to the above solution, the guide sleeve provided on the side of the lead screw nut is fitted onto the guide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This application is equipped with a lead screw, lead screw nut, limit switch, and movable plate. When it is necessary to monitor the material in the material storage box in real time, employees do not need to personally go to the material storage box for periodic inspections. The drive motor causes the lead screw to rotate, which in turn causes the limit switch, movable contact rod, and lower movable plate inside the housing to descend together until the lower movable plate touches the material in the material storage box. The top of the movable contact rod touches the contact of the limit switch, and the limit switch sends a signal to stop the motor and know whether the material in the material storage box has reached the pre-set warning threshold.
