Description

Technical Field

[0001] This utility model relates to the field of hopper technology, specifically to an unmanned hopper that prevents clogging. Background Technology

[0002] A hopper is a material conveying device that uniformly and continuously transports materials from storage containers to the next processing stage. It is widely used in industries such as chemical, building materials, and food processing, ensuring the continuity and efficiency of the production process. It typically consists of a frame, a feeding mechanism, and a limiting and supporting mechanism. The frame supports the entire hopper; the feeding mechanism includes the hopper and a turntable assembly, allowing the hopper to slide on the turntable assembly for replacement; the limiting and supporting mechanism restricts the position of the hopper, ensuring smooth material flow.

[0003] However, existing unmanned feeding hoppers designed to prevent clogging not only cause material buildup when feeding materials with high moisture content or inherent stickiness, leading to material adhering to the inner wall of the hopper and gradually forming a material layer, but also cause complete blockage when feeding materials with uneven particle shape and size, as large pieces of material tend to get stuck at the hopper opening and chute corners. Utility Model Content

[0004] This invention provides an unmanned feeding hopper that prevents clogging, which can crush materials to uniform size and prevent the gradual accumulation of material layers at the feed inlet, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an unmanned unblocking feeding hopper, including a top plate, with support columns fixedly connected to the four corners of the top plate, a material box fixedly connected to the top of the top plate, a discharge port at the bottom of the material box, an opening and closing component at the bottom of the discharge port, a partition on the outside of the discharge port, with the four corners of the partition fixedly connected to the support columns, a crushing mechanism to prevent clogging of the feeding hopper inside the material box, and a control mechanism with remote control function on one side of the material box.

[0006] Preferably, the opening and closing component includes two opening and closing hoppers disposed at the bottom of the discharge port. Two fixing blocks are fixedly connected to one side of the top of each of the two opening and closing hoppers. A first rotating shaft is fixedly connected inside each fixing block. The end of the first rotating shaft away from the fixing block is rotatably connected to the discharge port. A first gear is fixedly connected to the side of the fixing block away from the discharge port. The first gears mesh in pairs. A hydraulic cylinder is rotatably connected to the bottom of one of the opening and closing hoppers. The end of the hydraulic cylinder away from the opening and closing hopper is rotatably connected to the partition.

[0007] Preferably, the crushing mechanism includes two second rotating shafts rotatably mounted inside the material box. Crushing rollers are fixedly connected to the outer surface of the middle part of each of the two second rotating shafts. One end of each of the two second rotating shafts passes through the material box and extends to a second gear. The two second gears are respectively fixed to the outer surface of the second rotating shafts and mesh with each other. A motor is installed at the end of one of the second rotating shafts away from the second gear. The motor is fixedly connected to the output end of the material box. A rotating component is provided on one side of one of the second gears.

[0008] Preferably, the rotating component includes a first synchronous wheel fixedly mounted on the outer surface of the second rotating shaft. The first synchronous wheel is connected to the second synchronous wheel via a synchronous belt. A third rotating shaft is fixedly connected to the center of the second synchronous wheel. One end of the third rotating shaft passes through the connecting frame and extends into the interior of the discharge port. A stirring blade is fixedly connected to the third rotating shaft inside the discharge port. The connecting frame is fixedly connected to the discharge port.

[0009] Preferably, each of the two crushing rollers is provided with an inclined plate at its top, and the inclined plate is fixedly connected to the material box.

[0010] Preferably, the control mechanism includes a control box fixedly installed on one side of the material bin, six radar rangefinders fixedly connected to the bottom of the partition, traffic lights fixedly connected to one side of each of the two support columns, an audible and visual alarm fixedly installed on the support columns near the traffic lights, and a camera provided on one side of one of the radar rangefinders, the camera being fixedly connected to the partition.

[0011] This utility model has the following beneficial effects: 1. Through the combined action of the top plate, support column, material box, discharge port, opening and closing parts, partition, crushing mechanism and control mechanism, the material inside the material box can be squeezed and crushed, so that the volume of the material tends to be uniform, avoiding large pieces of material from getting stuck at the hopper opening or chute corners, and avoiding fine powder filling the gaps and forming bridging, which would cause the hopper to be blocked.

[0012] 2. Through the combined action of the top plate, support column, material box, discharge port, opening and closing parts, partition, crushing mechanism and control mechanism, the material at the discharge port can be continuously stirred and scraped, avoiding the problem of materials with high moisture content or sticky material adhering to the inner wall of the hopper, gradually forming a material layer accumulation, and as the accumulation thickness increases, the material channel narrows and eventually becomes completely blocked.

[0020] The opening and closing component 5 includes two opening and closing buckets 51 located at the bottom of the discharge port 4. Two fixing blocks 52 are fixedly connected to one side of the top of each of the two opening and closing buckets 51. A first rotating shaft 53 is fixedly connected inside each fixing block 52, which enables the opening and closing buckets 51 to rotate around the first rotating shaft 53. The end of the first rotating shaft 53 away from the fixing block 52 is rotatably connected to the discharge port 4. A first gear 54 is fixedly connected to the side of the fixing block 52 away from the discharge port 4. The first gears 54 mesh in pairs, which can control the two opening and closing buckets 51 to rotate synchronously, thereby achieving the purpose of controlling the two opening and closing buckets 51 to open and close. A hydraulic cylinder 55 is rotatably connected to the bottom of one of the opening and closing buckets 51. The end of the hydraulic cylinder 55 away from the opening and closing bucket 51 is rotatably connected to the partition plate 6.

[0021] The crushing mechanism 7 includes two second rotating shafts 71 rotatably mounted inside the material box 3. Crushing rollers 72 are fixedly connected to the outer surface of the middle part of the two second rotating shafts 71. One end of each of the two second rotating shafts 71 passes through the material box 3 and extends to the second gear 73. The two second gears 73 are respectively fixed to the outer surface of the second rotating shafts 71. The two second gears 73 mesh with each other, which enables the two crushing rollers 72 to rotate synchronously in opposite directions, thereby crushing the material. A motor 74 is installed at the end of one of the second rotating shafts 71 away from the second gear 73. The motor 74 is fixedly connected to the output end of the material box 3. A rotating part 75 is provided on one side of one of the second gears 73, which can stir the material at the discharge port 4.

[0022] In this embodiment: a drive motor 74 drives one of the second rotating shafts 71 to rotate. While the second rotating shaft 71 rotates, it drives the other second rotating shaft 71 to rotate in the opposite direction through the cooperation of the second gear 73. While the two second rotating shafts 71 rotate, they drive the crushing rollers 72 respectively. The two crushing rollers 72 continuously crush the material. Then, the hydraulic cylinder 55 is activated. The telescopic end of the hydraulic cylinder 55 pulls one of the opening buckets 51 to rotate and open. While the opening bucket 51 rotates, it drives the other locking bucket to rotate and open through the first gear 54. The crushed material falls into the vehicle through the discharge port 4.
