Description

Technical Field

[0001] This invention relates to the field of bulk grain unloading technology, specifically a bulk grain unloading machine. Background Technology

[0002] The status of grain trade in the international market is constantly rising, and the scale of trade is continuously expanding. At the same time, the global shipping industry is rapidly developing towards bulk grain handling, which makes bulk grain unloaders, as a high-performance continuous bulk cargo unloading machine, highly favored by ports, placing higher demands on their unloading efficiency and performance.

[0003] When unloading materials like wheat using a screw conveyor, the lifting section is vertically positioned. As the screw structure lifts the grain upwards for unloading, the grain is subjected to both upward screw thrust and centrifugal force generated by the rotation of the screw structure, causing it to flow outwards. This can lead to the material accumulating on the outer edge of the screw conveyor under the influence of centrifugal force and adhering tightly to the pipe wall. This can result in excessive friction between the material and the pipe wall, causing the material to become stuck between the screw conveyor and the pipe wall, resulting in grinding and shearing. This affects not only the unloading efficiency but also the integrity and quality of the material. Summary of the Invention

[0004] The purpose of this invention is to provide a special unloader for bulk grain to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0022] Furthermore, the top rotating disk is fixedly connected to the output end of motor two, and the bottom rotating disk is rotatably connected to the bottom inner wall of the rotating cylinder;

[0023] A screw conveyor is fixedly connected between the two rotating discs, and the screw conveyor is eccentrically positioned relative to the rotating discs.

[0024] Furthermore, the flexible layer is fixedly connected to the outer surface of the auger;

[0025] The elastic component includes a plurality of fixed cylinders fixedly connected to the outer surface of the auger, the plurality of fixed cylinders being arranged at equal intervals along the spiral line of the outer surface of the auger;

[0026] A spring shaft is slidably connected inside the fixed cylinder. The elastic end of the spring shaft is fixedly connected to the inner wall of the fixed cylinder. A threaded groove is opened on the outer surface of the spring shaft. A fixed plate is fixedly connected to the end of the spring shaft away from the fixed cylinder.

[0027] Furthermore, a sliding groove is provided on the side wall of the elastic spiral ring at the bottom of the fixed plate, and a T-shaped rod is fixedly connected to the bottom of the fixed plate, with the T-shaped rod slidably connected inside the sliding groove;

[0028] The limiting assembly includes a protruding rod that is slidably connected inside the threaded groove, a rotating ring that is fixedly connected to the side wall of the protruding rod, and a limiting ring that is rotatably connected to the outer surface of the rotating ring.

[0029] The limiting ring has three support rods fixedly connected to its side wall. The end of the support rod away from the limiting ring is fixedly connected to the side wall of the auger. The outer surface of the rotating ring has a long rod fixedly connected to it.

[0030] Furthermore, the flipping assembly includes a limiting block fixedly connected to the bottom outer wall of the rotating ring, a flipping plate rotatably connected to the side wall of the limiting block, a return spring fixedly connected to the top of the flipping plate, and the top of the return spring fixedly connected to the rotating ring.

[0031] Furthermore, the tops of several fixed shafts are fixedly connected to the arc surface of the auger;

[0032] The sliding assembly includes a curved plate slidably connected to the outer surface of the fixed shaft, the sidewall of the curved plate being in contact with the sidewall of the long rod;

[0033] The curved plate has a long groove on its side wall, and two rotating bars are slidably connected inside the long groove. The top of the rotating bars is rotatably connected to the arc surface of the auger.

[0034] A push spring is fixedly connected between the two rotating bars, and a push plate is fixedly connected to the bottom of the rotating bars.

[0035] The present invention has the following beneficial effects:

[0036] 1. This invention, through an auxiliary component, utilizes the recesses formed by the flexible layer to actively guide materials away from the inner wall of the discharge pipe. This reduces the accumulation of materials near the inner wall of the discharge pipe due to centrifugal force during the auger's rotation. It also reduces the frictional resistance between the material and the inner wall of the discharge pipe caused by centrifugal force during vertical discharge, as well as the possibility of some materials getting stuck. This prevents grinding and shearing of the material during discharge, thereby improving discharge efficiency while enhancing the integrity and quality of the material.

[0037] 2. In this invention, through the flipping component and the limiting component, when the rotating ring rotates, it will drive the flipping plate to rotate synchronously through the limiting block. At this time, the flipping plate will rotate on the surface of the limiting block under the elastic release of the bending spring. The rotating flipping plate will rotate to the recess formed by the flexible layer. At this time, the flipping plate will form a blocking layer in the recess of the flexible layer. By blocking the material in the recess, the backflow of material under the action of gravity or centrifugal force when the material slides into the recess formed by the flipping plate can be reduced. This reduces the backflow of material during vertical unloading, improves the stability of the material during transportation, and improves the subsequent unloading efficiency.

[0038] 3. In this invention, through the sliding component and the flipping component, when the flexible layer is reset, the spring shaft will push the elastic spiral ring under the release of its own spring potential energy, causing it to drive the flexible layer to reset. Since the side wall of the push plate is blocked by the accumulated material, the rotating bar can push the accumulated material to both sides under the release of the spring potential energy, so that the material can be distributed on the surface of the flexible layer during the unloading process. This reduces the material accumulation on the side wall of the flipping plate due to the obstruction of the flexible layer, and reduces the intermittent unloading caused by the accumulation of material due to the obstruction of the flipping plate. This improves the continuity and smoothness of the unloading process and enhances the unloading efficiency.

[0039] 4. In this invention, because the push plate is blocked by the accumulated material on both sides, the rotating bar can slowly open under the release of the spring potential energy. Since the long rod rotates faster with the rotating ring while the opening speed of the push plate and the rotating bar is slower, the slow sliding of the bending plate is likely to be in the top area of ​​the flexible layer after the flexible layer and the long rod are reset. By slowly resetting the rotating bar and the bending plate, the jumping of the material after the flexible layer is reset can be reduced due to the fast reset speed of the flexible layer and the eccentric movement of the auger. By blocking the material at the top of the material, the impact of the jumping of the material on the unloading speed with the rotation of the auger can be reduced, and the stability of the material position and the continuity of unloading can be further enhanced.

[0040] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0067] The sliding component 31 is mounted on the outer surface of the fixed shaft 301.

[0068] Support assembly 11 includes a motor 111 fixedly connected to the top of the main body 1. A drive rod 112 is fixedly connected to the output end of the motor 111. A gear is fixedly connected to the end of the drive rod 112 away from the motor 111.

[0069] The rotating assembly 12 includes a rotating cylinder 121 rotatably connected to the bottom of the discharge pipe 101. The outer surface of the rotating cylinder 121 is meshed with a gear, and a plurality of inlets 122 are opened on the outer surface of the rotating cylinder 121.

[0070] The auxiliary component 13 includes a second motor 131 fixedly connected to the top outer wall of the main body 1, and two rotating disks 132 are provided at the bottom of the second motor 131.

[0071] The top rotating disk 132 is fixedly connected to the output end of the second motor 131, and the bottom rotating disk 132 is rotatably connected to the bottom inner wall of the rotating cylinder 121.

[0072] A screw conveyor 133 is fixedly connected between the two rotating disks 132. The screw conveyor 133 and the rotating disks 132 are eccentrically positioned. When the first motor 111 is working, it drives the rotating cylinder 121 to rotate through the drive rod 112 and gear. At the same time, the second motor 131 is started. When the second motor 131 rotates, it drives the screw conveyor 133 to rotate through the rotating disks 132. At this time, the rotating cylinder 121 and the screw conveyor 133 will rotate in opposite directions.

[0073] The flexible layer 201 is fixedly connected to the outer surface of the auger 133;

[0074] The elastic component 21 includes a plurality of fixed cylinders 211 fixedly connected to the outer surface of the auger 133, and the plurality of fixed cylinders 211 are arranged at equal intervals along the spiral line of the outer surface of the auger 133.

[0075] A spring shaft 212 is slidably connected inside the fixed cylinder 211. The elastic end of the spring shaft 212 is fixedly connected to the inner wall of the fixed cylinder 211. A threaded groove is opened on the outer surface of the spring shaft 212. A fixed plate 213 is fixedly connected to the end of the spring shaft 212 away from the fixed cylinder 211. When the spring shaft 212 slides, it will slide inside the fixed cylinder 211. When the spring shaft 212 slides, the protrusion inside the rotating ring 221 will be guided by the threaded groove on the surface of the spring shaft 212, so that the rotating ring 221 will rotate when the spring shaft 212 slides. When the rotating ring 221 rotates, it will drive the flip plate 232 to rotate synchronously through the limit block 231.

[0076] A sliding groove is provided on the side wall of the elastic spiral ring 202 at the bottom of the fixed plate 213, and a T-shaped rod is fixedly connected to the bottom of the fixed plate 213. The T-shaped rod is slidably connected inside the sliding groove.

[0077] The limiting component 22 includes a protruding rod that is slidably connected inside the threaded groove. A rotating ring 221 is fixedly connected to the side wall of the protruding rod, and a limiting ring 222 is rotatably connected to the outer surface of the rotating ring 221.

[0078] Among them, the side wall of the limiting ring 222 is fixedly connected with three support rods, and the end of the support rod away from the limiting ring 222 is fixedly connected to the side wall of the auger 133. The outer surface of the rotating ring 221 is fixedly connected with a long rod 223.

[0079] The flipping assembly 23 includes a limiting block 231 fixedly connected to the bottom outer wall of the rotating ring 221. A flipping plate 232 is rotatably connected to the side wall of the limiting block 231. A return spring is fixedly connected to the top of the flipping plate 232. The top of the return spring is fixedly connected to the rotating ring 221. When the rotating ring 221 rotates during the sliding of the spring shaft 212, the rotation of the rotating ring 221 will drive the long rod 223 to rotate synchronously. When the long rod 223 rotates, it will push the top of the bending plate 311 to slide downward on the surface of the fixed shaft 301. When the bending plate 311 slides downward, it will squeeze the side walls of the two rotating bars 312, causing the two rotating bars 312 to rotate relative to each other. At this time, the pushing spring between the two rotating bars 312 will be in a compressed state.

[0080] The tops of several fixed shafts 301 are fixedly connected to the arc surface of the auger 133, such as... Figure 6 As shown in B;

[0081] The sliding assembly 31 includes a curved plate 311 that is slidably connected to the outer surface of the fixed shaft 301, and the sidewall of the curved plate 311 is in contact with the sidewall of the long rod 223.

[0082] Among them, the side wall of the curved plate 311 is provided with a long groove, and two rotating bars 312 are slidably connected inside the long groove. The top of the rotating bars 312 is rotatably connected to the arc surface of the auger 133.

[0083] A push spring is fixedly connected between the two rotating bars 312, and a push plate 313 is fixedly connected to the bottom of the rotating bars 312. When the two rotating bars 312 rotate and close, the push plate 313 will be inserted into the accumulated material. Then, when the flexible layer 201 is reset, the spring shaft 212 will push the elastic spiral ring 202 under the release of its own spring potential energy, so that it will drive the flexible layer 201 to reset.

[0084] In use, firstly, the discharge pipe located on the outer surface of the conical cylinder at the top of the discharge pipe 101 is connected to the horizontal screw conveyor on the unloading machine. Then, the main body 1 is connected to the drive equipment on the unloading ship. The drive equipment then drives the main body 1 to insert the rotating drum 121 into the grain inside the ship's hull. Then, the first motor 111 is started. When the first motor 111 is working, it drives the rotating drum 121 to rotate through the drive rod 112 and gear. At the same time, the second motor 131 is started. When the second motor 131 rotates, it drives the auger 133 to rotate through the rotating disk 132. At this time, the rotating drum 121 and the auger 133 rotate in opposite directions. The rotation of the rotating drum 121 can collect the grain into the rotating drum 121 through the feed port 122 and be vertically transported into the horizontal screw conveyor by the rotating auger 133, thus completing the unloading of the grain.

[0085] When motor 131 drives the rotating disk 132 to rotate, the auger 133 and the rotating disk 132 are eccentrically positioned. As motor 131 drives the rotating disk 132 to rotate, the rotation of the rotating disk 132 causes the auger 133 to move eccentrically within the discharge pipe 101. When the auger 133 moves eccentrically within the discharge pipe 101, its rotation, through the flexible layer 201 and the elastic spiral ring 202, vertically conveys the material. Simultaneously, the eccentric rotation of the auger 133 causes the inner wall of the discharge pipe 101 to periodically compress the elastic spiral ring 202. When one side of the elastic spiral ring 202 is compressed due to the eccentric rotation of the auger 133, the flexible layer 201 will... The flexible layer 201 relaxes and becomes concave, allowing the vertically conveyed material to slide down into the concave area formed by it under its own gravity. The concave area formed by the flexible layer 201 actively guides the material away from the inner wall of the discharge pipe 101, reducing the accumulation of material near the inner wall of the discharge pipe 101 due to centrifugal force when the auger 133 rotates. This also reduces the frictional resistance between the material and the inner wall of the discharge pipe 101 caused by centrifugal force during vertical discharge, as well as the possibility of some material getting stuck. This reduces the risk of grinding and shearing the material during discharge, thus improving discharge efficiency while also enhancing the integrity and quality of the material.

[0086] When the elastic spiral ring 202 is squeezed by the inner wall of the discharge pipe 101 under the eccentric motion of the auger 133, the elastic spiral ring 202 will slide by squeezing the spring shaft 212 through the fixed plate 213. When the spring shaft 212 slides, it will slide inside the fixed cylinder 211. When the spring shaft 212 slides, the protrusion inside the rotating ring 221 will be guided by the thread groove on the surface of the spring shaft 212, so that the rotating ring 221 will rotate when the spring shaft 212 slides. When the rotating ring 221 rotates, it will drive the flipping plate 232 to rotate synchronously through the limit block 231. At this time, the flip plate 232 will rotate on the surface of the limit block 231 under the elastic release of the bending spring. The rotating flip plate 232 will rotate to the recess formed by the flexible layer 201. At this time, the flip plate 232 will form a blocking layer in the recess of the flexible layer 201. The blocking of the flip plate 232 in the recess can reduce the backflow of material under the action of gravity or centrifugal force when the material slides into the recess formed by the flexible layer 201. This reduces the backflow of material during vertical unloading, improves the stability of material during conveying, and improves the subsequent unloading efficiency.

[0087] When the rotating ring 221 rotates while sliding on the spring shaft 212, the rotation of the rotating ring 221 will drive the long rod 223 to rotate synchronously. When the long rod 223 rotates, it will push the top of the bending plate 311, causing it to slide downward on the surface of the fixed shaft 301. When the bending plate 311 slides downward, it will squeeze the side walls of the two rotating bars 312, causing the two rotating bars 312 to rotate relative to each other. At this time, the push spring between the two rotating bars 312 will be in a compressed state. When the two rotating bars 312 rotate and close, the push plate 313 will be inserted into the accumulated material. Subsequently, when the flexible layer 201 resets, the spring shaft 212 will be in its own spring. The release of potential energy pushes the elastic spiral ring 202, causing it to reset the flexible layer 201. Because the side wall of the push plate 313 is blocked by the accumulated material, the rotating bar 312 can push the accumulated material to both sides under the release of the potential energy of the push spring. This allows the material to be distributed on the surface of the flexible layer 201 during the unloading process, reducing the material accumulation on the side wall of the flip plate 232 caused by the obstruction of the flip plate 232 in the recess of the flexible layer 201. This also reduces the intermittent unloading caused by the obstruction of the flip plate 232, thereby improving the continuity and smoothness of the unloading process and enhancing the unloading efficiency.

[0088] Because the push plate 313 is blocked by the accumulated material on both sides, the rotating bar 312 can slowly open under the release of the spring potential energy. Since the long rod 223 rotates faster with the rotating ring 221, while the opening speed of the push plate 313 and the rotating bar 312 is slower, the bending plate 311 will slowly slide in the top area of ​​the flexible layer 201 after the flexible layer 201 and the long rod 223 are reset. Through the slow reset of the rotating bar 312 and the bending plate 311, the jumping of the material after the flexible layer 201 is reset can be reduced due to the fast reset speed of the flexible layer 201 and the eccentric movement of the auger 133. By blocking the material at the top of the material, the impact of the jumping of the material on the unloading speed of the auger 133 can be reduced, and the stability of the material position and the continuity of unloading can be further enhanced.

[0089] When resetting, the two rotating bars 312 push the bending plate 311 upward through their side walls to reset.

[0090] It should be noted that the two push plates 313 will be in a relatively circular state when the rotating bar 312 is closed, so that the two rotating bars 312 will not be in a parallel state, thereby reducing the impact on the subsequent reset and the stable operation of pushing the bending plate 311 to move upward when the two rotating bars 312 rotate relative to each other.
