Technical Field

[0001] The present invention relates to the technical field of terminal loading and unloading equipment, in particular to a bulk grain terminal loading and unloading ship dual-purpose machine. Background Art

[0002] The dual-purpose loading and unloading machine for bulk grain terminals is a large-scale mechanical equipment used in bulk grain terminals, integrating the functions of bulk grain loading and unloading. Continuous loaders include chain bucket loaders, screw loaders, bucket wheel loaders, and entrainer loaders. The core function of the dual-purpose machine is to achieve efficient two-way loading and unloading operations through a single device, solving the pain point that traditional terminals need to be equipped with unloaders and loaders separately, thereby optimizing port operating efficiency and costs.

[0003] Among them, when loading and unloading grain, a spiral loader is often used. When unloading, the grain in the ship usually needs to be transported vertically, but some grains have poor fluidity, such as corn, brown rice, etc. When the spiral blades rotate, due to the large friction between the grain particles, it may be difficult to push some particles to move, causing some particles to accumulate at the bottom of the spiral blades. This may cause the spiral blades to squeeze the accumulated particles when rotating, causing them to be damaged, affecting the integrity of the grain. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a bulk grain terminal loading and unloading dual-purpose machine, comprising a conveyor body and a frame, wherein the top of the conveyor body is fixedly connected to a discharge hopper, the bottom of the conveyor body is rotatably connected to the outer wall of the frame, and the bottom of the conveyor body is rotatably connected to a support frame; The loading and unloading mechanism has a shifting assembly installed at the bottom thereof, and a discharge assembly is rotatably provided at the side wall thereof, and the shifting assembly is used for conveying grain; A conveying mechanism, which is installed on the inner wall of the discharge assembly and is used to load or unload grain; and An anti-blocking mechanism is located on the inner wall of the conveying mechanism and is used to squeeze out lumps in the grain; A conical sleeve is provided at the bottom of the conveyor body, a connecting rod is slidably connected to the inner wall of the conical sleeve, and a spring extrusion ring is slidably connected to the inner wall of the conical sleeve; Among them, grain is loaded or unloaded on the ship through the loading and unloading mechanism and the conveying mechanism. During the unloading process, the anti-blocking mechanism is used to reduce the friction between the grain particles, enhance the fluidity of the grain particles, and effectively prevent the poor fluidity of the grain particles from causing the accumulation of particles, causing the particles to be squeezed and easily cause the particles to be damaged, thereby ensuring the integrity of the grain particles and allowing the conveying mechanism to transport the grain quickly.

[0005] Preferably, the loading and unloading mechanism includes: A shifting assembly, the outer wall of which is rotatably arranged with the bottom of the conveyor body, for conveying grain; A discharge assembly, the inner wall of which is rotatably arranged with the bottom of the conveyor body, is used to guide the flow of grain; When loading is required, the grain is sent into the discharge assembly through the shifting assembly, enters the conveying mechanism through the discharge assembly, and is then discharged into the cabin through the conveying mechanism.

[0006] Preferably, the conveying mechanism comprises: A driving assembly is fixed to the inner wall of the support frame through a fixing member and is used to control the moving direction of the grain; The fixing member includes a material delivery pipe fixedly connected to the inner wall of the support frame, and a rotating rod is rotatably connected to the inner wall of the material delivery pipe; A feed assembly is rotatably arranged on the outer wall of the delivery pipe by a rotating member and is used to fill the driving assembly; The rotating member includes a spiral cylinder rotatably connected to the outer wall of the material conveying pipeline, and a gear ring is fixedly connected to the outer wall of the spiral cylinder; Among them, when unloading is required, the driving component and the feeding component are started, and the driving component and the feeding component are rotated in opposite directions, and the grain is fed into the spiral drum through the feeding component. Finally, the driving component transports the grain upward and transports the grain to the conveyor body. Finally, the conveyor body is started to transport the grain and complete the unloading in the cabin.

[0007] Preferably, the anti-blocking mechanism includes: An air jet assembly is rotatably arranged on the inner wall of the conical sleeve through a support member and is used to disperse grain particles; The support member includes a concave-convex ring rotatably connected to the inner wall of the conical sleeve, and eight blocking rods are fixedly connected to the top of the spring extrusion ring; An extrusion assembly is fixedly arranged at the bottom of the spring extrusion ring through a connecting piece and is used to squeeze out lumps in the grain particles; The connecting member includes two F-shaped rods fixedly connected to the bottom of the spring extrusion ring, and four blocking frames are fixedly connected to the outer wall of the rotating rod; Among them, when the driving component rotates, the jet component will be squeezed, and high-pressure gas will be sprayed towards the grain particles, which will promote the dispersion of particles, reduce the friction between grain particles, enhance the fluidity of grain particles, and facilitate the transportation of particles. At the same time, it will drive the extrusion component to move, squeezing the particles that have agglomerated into lumps, effectively preventing grain from clumping. The agglomerates have poor fluidity and are easily blocked in the spiral barrel, affecting the transportation of grain.

[0008] Preferably, the shifting assembly includes a hydraulic cylinder fixedly connected to the inner wall of the frame, a traverse rod is slidably connected to the inner wall of the frame, and a push rod is rotatably connected to the bottom of the conveyor body; The output end of the side wall of the hydraulic cylinder is fixedly connected to the side wall of the transverse rod, and the side of the transverse rod away from the hydraulic cylinder is rotatably connected to the inner wall of the push rod; Among them, by retracting the hydraulic cylinder, the transverse rod is pulled away from the material conveying pipeline, the push rod is rotated, the inclination angle between the push rod and the conveyor body is changed, the conveyor body is pulled to rotate, the right side of the conveyor body is lowered, the support frame and the material conveying pipeline are lowered, the material conveying pipeline enters the cabin, and the drive assembly is lowered.

[0009] Preferably, the discharge assembly includes an inclined plate fixedly connected to the inner wall of the support frame, a spring slide is slidably connected to the inner wall of the inclined plate, and a roller is rotatably connected to the inner wall of the spring slide.

[0010] Preferably, the driving assembly includes a motor 1 fixedly connected to the top of the support frame, the bottom output end of the motor 1 is fixedly connected to the top of the rotating rod, and a spiral auger is fixedly connected to the outer wall of the rotating rod; Among them, when the material conveying pipeline is lowered and extended into the cabin, the material is supplied to the material conveying pipeline by starting the feeding component, and then the spiral auger is rotated by starting the motor to convey the material upward.

[0011] Preferably, the feeding assembly includes a second motor fixedly connected to the outer wall of the feeding pipe, the bottom output end of the second motor is fixedly connected to a gear rod, and the outer wall of the gear rod is meshed with the outer wall of the gear ring; A connecting frame is fixedly connected to the side wall of the conveyor body, a motor 3 is fixedly connected to the side wall of the connecting frame, and an output end of the motor 3 is fixedly connected to the side wall of the support frame; Among them, when the feeding pipeline descends and the spiral drum is extended into the cabin, the gear rod is driven to rotate by starting motor 2, and the gear rod drives the gear ring to rotate, so that the spiral drum rotates, and the spiral drum rotates in the opposite direction of rotation to the spiral auger. Through the rotation of the spiral drum, the grain particles are sent into the interior of the spiral drum. At the same time, the spiral auger is rotated to vertically transport the grain particles entering the spiral drum upward. The grain transported to the top of the feeding pipeline will be discharged through the opening of the feeding pipeline to the top of the inclined plate and the spring slide plate, and slide along the inclined surface of the inclined plate to the conveyor body. Finally, the conveyor body is started to transport the grain, completing the unloading in the cabin.

[0012] Preferably, the jet assembly includes eight exhaust pipes connected through the inner wall of the conical sleeve, the inner walls of the eight exhaust pipes are slidably connected to the outer walls of the eight blocking rods, and the outer wall of the connecting rod is fixedly connected to the inner wall of the concave-convex ring; The top of the connecting rod is fixedly connected to the bottom of the rotating rod, and the inner wall of the conical sleeve and the spiral cylinder are both provided with special-shaped grooves; Among them, when the rotating rod rotates, it will drive the connecting rod to rotate, causing the concave-convex ring to rotate. When the convex position of the concave-convex ring contacts the bottom of the spring extrusion ring, the spring extrusion ring will be lifted up, accumulating rebound force. After the spring extrusion ring rises to cover the special-shaped groove, it will squeeze the gas in the conical sleeve. At this time, the squeezed gas will be blocked by the blocking rod, so the gas pressure will increase. As the blocking rod continues to move, the blocking rod will separate from the exhaust pipe, leaving a gap between the two. The high-pressure gas will be ejected through the gap towards the grain particles in the spiral barrel. When the convex position of the concave-convex ring separates from the spring extrusion ring, the rebound of the spring extrusion ring The force will be released, allowing the spring extrusion ring to return to its position, allowing the special-shaped groove to connect with the top of the spring extrusion ring again, and the external gas will enter the conical sleeve through the special-shaped groove to replenish the gas until the concave-convex ring lifts the spring extrusion ring again, and so on. High-pressure gas is continuously sprayed to the grain particles. The high-pressure gas will penetrate into the gaps between the grain particles to form an air cushion effect, reduce the friction between the grain particles, enhance the fluidity of the grain particles, and facilitate the conveying of the grains by the spiral auger. It can effectively prevent the poor fluidity of the grain particles from causing the particles to accumulate at the bottom of the spiral auger, causing the particles to be squeezed and easily damaged, thereby ensuring the integrity of the grain particles.

[0013] Preferably, the extrusion assembly includes a sliding frame slidably connected to the inner wall of the rotating rod, the outer wall of the sliding frame is slidably connected to the inner wall of the connecting rod, and the outer walls of the four blocking frames are slidably connected to two sliding blocking rods; Eight sliding sleeves are fixedly connected to the inner wall of the rotating rod, and spring blocks are slidably connected to the inner walls of the eight sliding sleeves. The side walls of the eight spring blocks are fixedly connected to the side walls of the sliding blocking rod; When the grain particles accumulate in the cabin and the grain accumulates in a cone shape, the grain accumulated at the bottom is prone to agglomeration, and the agglomerates have poor fluidity, which can easily cause blockage. When the spring extrusion ring rises, it will drive the F-shaped rod to rise. As the F-shaped rod continues to move, the F-shaped rod will contact the sliding frame, pushing the sliding frame to rise, and the sliding frame will push the spring block and the sliding baffle rod to rise, allowing the spring block to accumulate rebound force. When the spring extrusion ring falls, the rebound force of the spring block will be released, pushing the sliding baffle rod down. When the agglomerated grain particles are conveyed by the spiral auger, larger agglomerates will be blocked by the sliding baffle rod and the blocking frame. When the sliding baffle rod rises and falls, the distance between the sliding baffle rod and the blocking frame will change. When the agglomerate moves to the middle of the blocking frame and the sliding baffle rod, the sliding baffle rod will squeeze the agglomerate, disperse the agglomerate, restore the fluidity of the grain particles, and effectively prevent grain from agglomerating. However, the poor fluidity of the agglomerate can easily cause the agglomerate to be blocked in the spiral barrel, affecting the transportation of grain.

[0014] The present invention has the following beneficial effects: (1) When the present invention is used, when it is necessary to unload the material from the ship, the material delivery pipe is moved into the cabin by moving the assembly, and then the motor 1 and the motor 2 are started to rotate the spiral drum and the spiral auger, and the driving assembly and the feeding assembly are used to make the two rotate in opposite directions, and the grain is delivered to the conveyor body to complete the unloading in the cabin. When the rotating rod rotates, it will drive the connecting rod to rotate, and the concave and convex rings will rotate, and the extrusion push assembly will rise, squeezing the gas, and finally the high-pressure gas will be sprayed toward the grain particles, penetrating into the gaps between the grain particles to form an air cushion effect, reducing the friction between the grain particles, enhancing the fluidity of the grain particles, and facilitating the conveyance of the particles by the spiral auger, effectively preventing the poor fluidity of the grain particles from causing the particles to accumulate at the bottom of the spiral auger, causing the particles to be squeezed and easily damaged, thereby ensuring the integrity of the grain particles.

[0015] (2) The present invention aims to solve the problem that grain particles accumulate in the cabin and the grain accumulation is in a cone shape. The grain accumulated at the bottom is easy to clump, and the agglomerates have poor fluidity and are easy to cause blockage. When the spring extrusion ring rises, it will drive the F-shaped rod to rise, pushing the sliding frame to rise. The sliding frame will push the spring block and the sliding baffle to rise. When the spring extrusion ring falls, the sliding baffle will fall, and the agglomerated grain will be blocked by the sliding baffle and the baffle. In the process of the sliding baffle rising and falling, the agglomerates will be squeezed to disperse the agglomerates, restore the fluidity of the grain particles, and effectively prevent the agglomerates from agglomerating. The agglomerates have poor fluidity and are easy to cause the agglomerates to be blocked in the spiral barrel, affecting the transportation of the grain.

[0016] (3) In the present invention, after the spring extrusion ring rises to cover the special-shaped groove, the external gas will enter the bottom of the spring extrusion ring through the special-shaped groove. When the rebound force of the spring extrusion ring is released, the spring extrusion ring will fall, which will squeeze the gas and discharge it from the special-shaped groove. Since the special-shaped groove has multiple complex flow channels, the flow speed of the gas will be slowed down, thereby slowing down the descending speed of the spring extrusion ring and the descending speed of the sliding baffle, effectively preventing the rebound force of the spring block from being released too quickly and the sliding baffle from falling quickly, which will produce a large impact force on the grain particles and cause damage to the grain particles.

[0017] (4) When the ship's cabin needs to be loaded, the present invention raises the right side of the conveyor body by moving the assembly, so that the support frame rises, and the grain is sent into the feeding pipe through the conveyor body. At this time, the motor is started to reverse the rotation of the rotating rod and the spiral auger, and the grain is transported downward, and the grain particles are discharged from the opening of the spiral barrel into the ship's cabin. At the same time, the rotating rod also drives the concave and convex ring to rotate, so that the spring extrusion ring rises, and the exhaust pipe sprays high-pressure gas towards the descending grain particles, which will slow down the descending speed of the grain particles and effectively prevent the grain particles from falling too fast and causing impact on the top of the conical sleeve, which may easily cause damage to the surface of the grain particles and affect subsequent transportation and storage.

During the unloading process, the friction between the grain particles is reduced by the anti-blocking mechanism 3, the fluidity of the grain particles is enhanced, and the poor fluidity of the grain particles is effectively prevented, which leads to the accumulation of particles and the squeezing of the particles, which easily leads to the breakage of the particles. The integrity of the grain particles is ensured, and the conveying mechanism 2 can quickly convey the grain.

[0024] The conveying mechanism 2 includes: The driving assembly 21 is fixed to the inner wall of the support frame 121 through a fixing member and is used to control the movement direction of the grain; The fixing member includes a material delivery pipe 211 fixedly connected to the inner wall of the support frame 121, and a rotating rod 212 is rotatably connected to the inner wall of the material delivery pipe 211; The feeding assembly 22 is rotatably arranged on the outer wall of the feeding pipe 211 by a rotating member, and is used to fill the driving assembly 21; The rotating member includes a spiral cylinder 221 rotatably connected to the outer wall of the material delivery pipe 211, and a gear ring 222 is fixedly connected to the outer wall of the spiral cylinder 221; Among them, when unloading is required, the driving component 21 and the feeding component 22 are started, and the driving component 21 and the feeding component 22 are rotated in opposite directions, and the grain is supplied into the spiral drum 221 through the feeding component 22, and finally the driving component 21 transports the grain upward and transports the grain to the conveyor body 111, and finally the conveyor body 111 is started to transport the grain, completing the unloading in the cabin.

At the same time, it will drive the extrusion component 32 to move, squeezing the particles that have agglomerated into blocks, effectively preventing the grain from agglomerating. The fluidity of the agglomerates is poor, and the agglomerates are easily blocked in the spiral barrel 221, affecting the transportation of the grain.

[0026] For example 2, please refer to Figures 1-11 The present invention is a dual-purpose machine for loading and unloading ships at a bulk grain terminal. Based on Example 1, the shifting assembly 11 includes a hydraulic cylinder 114 fixedly connected to the inner wall of a frame 113, a transverse rod 115 slidably connected to the inner wall of the frame 113, and a push rod 116 rotatably connected to the bottom of the conveyor body 111; The output end of the side wall of the hydraulic cylinder 114 is fixedly connected to the side wall of the transverse rod 115, and the side of the transverse rod 115 away from the hydraulic cylinder 114 is rotatably connected to the inner wall of the push rod 116; Among them, by retracting the hydraulic cylinder 114, the transverse rod 115 is pulled away from the material delivery pipe 211, the push rod 116 is rotated, the inclination angle between the push rod 116 and the conveyor body 111 is changed, and the conveyor body 111 is pulled to rotate, so that the right side of the conveyor body 111 is lowered, the support frame 121 and the material delivery pipe 211 are lowered, the material delivery pipe 211 enters the cabin, and the drive assembly 21 is lowered.

[0027] The discharge assembly 12 includes an inclined plate 122 fixedly connected to the inner wall of the support frame 121 , a spring slide 123 is slidably connected to the inner wall of the inclined plate 122 , and a roller 124 is rotatably connected to the inner wall of the spring slide 123 .

[0028] The driving assembly 21 includes a motor 213 fixedly connected to the top of the support frame 121. The bottom output end of the motor 213 is fixedly connected to the top of the rotating rod 212. The outer wall of the rotating rod 212 is fixedly connected to a spiral auger 214. Among them, when the material delivery pipe 211 is lowered and extended into the cabin, the material is supplied to the material delivery pipe 211 by starting the feeding component 22, and then the motor 213 is started to rotate, so that the spiral auger 214 rotates and the material is transported upward.

[0029] The feed assembly 22 includes a second motor 223 fixedly connected to the outer wall of the feed pipe 211. The bottom output end of the second motor 223 is fixedly connected to a gear rod 224. The outer wall of the gear rod 224 is meshed with the outer wall of the gear ring 222. The side wall of the conveyor body 111 is fixedly connected to a connecting frame 225, the side wall of the connecting frame 225 is fixedly connected to a motor 3 226, and the output end of the motor 3 226 is fixedly connected to the side wall of the support frame 121; Among them, when the feeding pipe 211 descends and the spiral drum 221 is extended into the cabin, the gear rod 224 is driven to rotate by starting the second motor 223, and the gear rod 224 drives the gear ring 222 to rotate, so that the spiral drum 221 rotates, and the spiral drum 221 rotates in the opposite direction of rotation to the spiral auger 214. Through the rotation of the spiral drum 221, the grain particles are sent into the interior of the spiral drum 221. At the same time, the spiral auger 214 is rotated to vertically transport the grain particles entering the spiral drum 221. The grain transported to the top of the feeding pipe 211 will be discharged through the opening of the feeding pipe 211 to the top of the inclined plate 122 and the spring slide plate 123, and slide along the inclined surface of the inclined plate 122 to the conveyor body 111. Finally, the conveyor body 111 is started to transport the grain, completing the unloading in the cabin.

[0030] The jet assembly 31 includes eight exhaust pipes 316 that are connected to the inner wall of the conical sleeve 311. The inner walls of the eight exhaust pipes 316 are slidably connected to the outer walls of the eight blocking rods 315. The outer wall of the connecting rod 312 is fixedly connected to the inner wall of the concave-convex ring 314. The top of the connecting rod 312 is fixedly connected to the bottom of the rotating rod 212, and the inner walls of the conical sleeve 311 and the spiral cylinder 221 are both provided with special-shaped grooves 317; When the rotating rod 212 rotates, the connecting rod 312 is driven to rotate, causing the concave-convex ring 314 to rotate. When the raised position of the concave-convex ring 314 contacts the bottom of the spring extrusion ring 313, the spring extrusion ring 313 is lifted up, accumulating rebound force. After the spring extrusion ring 313 rises and covers the special-shaped groove 317, it will squeeze the gas in the conical sleeve 311. At this time, the squeezed gas will be blocked by the blocking rod 315, so the gas pressure will increase. As the blocking rod 315 continues to move, the blocking rod 315 will separate from the exhaust pipe 316, leaving a gap between the two. The high-pressure gas will be ejected through the gap towards the food particles in the spiral cylinder 221. When the raised position of the concave-convex ring 314 separates from the spring extrusion ring 313, The rebound force of the spring extrusion ring 313 will be released, allowing the spring extrusion ring 313 to return to its original position, allowing the special-shaped groove 317 to connect with the top of the spring extrusion ring 313 again, and the external gas will enter the conical sleeve 311 through the special-shaped groove 317 to replenish the gas until the concave-convex ring 314 lifts the spring extrusion ring 313 again, and so on. High-pressure gas is continuously sprayed to the grain particles, and the high-pressure gas will penetrate into the gaps between the grain particles to form an air cushion effect, reduce the friction between the grain particles, enhance the fluidity of the grain particles, and facilitate the particles to be transported by the spiral auger 214, effectively preventing the poor fluidity of the grain particles from causing the particles to accumulate at the bottom of the spiral auger 214, causing the particles to be squeezed, which can easily cause the particles to be damaged, thereby ensuring the integrity of the grain particles.

[0031] The extrusion assembly 32 includes a sliding frame 322 slidably connected to the inner wall of the rotating rod 212. The outer wall of the sliding frame 322 is slidably connected to the inner wall of the connecting rod 312. The outer walls of the four blocking frames 323 are each slidably connected to two sliding blocking rods 324. Eight sliding sleeves 325 are fixedly connected to the inner wall of the rotating rod 212. The inner walls of the eight sliding sleeves 325 are all slidably connected to spring blocks 326. The side walls of the eight spring blocks 326 are all fixedly connected to the side walls of the sliding blocking rod 324. The spring block 326 and the sliding block 324 are pushed up by the spring extrusion ring 313, and the spring block 326 and the sliding block 324 are pushed up by the spring extrusion ring 313. The movable baffle 324 descends, and when the agglomerated grain particles are conveyed by the spiral auger 214, the larger agglomerates will be blocked by the sliding baffle 324 and the blocking frame 323. When the sliding baffle 324 rises and falls, the distance between the sliding baffle 324 and the blocking frame 323 will change. When the agglomerate moves to the middle of the blocking frame 323 and the sliding baffle 324, the sliding baffle 324 will squeeze the agglomerate to disperse it, restore the fluidity of the grain particles, and effectively prevent the grain from agglomerating. However, the agglomerate has poor fluidity, which can easily cause the agglomerate to be blocked in the spiral barrel 221, affecting the conveyance of the grain.

[0033] A specific application of this embodiment is as follows: when the present invention is used, the operator moves the device to the vicinity of the ship that needs to be loaded or unloaded. When the ship needs to be unloaded, the hydraulic cylinder 114 is retracted to pull the transverse rod 115 away from the conveying pipe 211, so that the push rod 116 rotates, the inclination angle between the push rod 116 and the conveyor body 111 is changed, and the conveyor body 111 is pulled to rotate, so that the right side of the conveyor body 111 drops, and the support frame 121 and the conveying pipe 211 drop, so that the conveying pipe 211 enters the cabin. At the same time, the motor 223 is started to drive the support frame 121 to rotate toward the conveyor body 111, so that the support frame 121 remains in a vertical state. Figure 10 As shown, when the support frame 121 rotates, the roller 124 contacts the conveyor body 111, causing the spring slide 123 to be squeezed and retracted into the roller 124, accumulating rebound force; After that, the motor 1 213 is started to drive the rotating rod 212 to rotate, so that the auger 214 rotates. At the same time, the motor 223 is started to drive the gear rod 224 to rotate, so that the gear rod 224 drives the gear ring 222 to rotate, so that the spiral drum 221 rotates, and the spiral drum 221 rotates in the opposite direction to the spiral auger 214. Through the rotation of the spiral drum 221, the grain particles are sent into the interior of the spiral drum 221. At the same time, the auger 214 is rotated to vertically transport the grain particles entering the spiral drum 221. The grain transported to the top of the feeding pipe 211 will be discharged through the opening of the feeding pipe 211 to the top of the inclined plate 122 and the spring slide plate 123, and slide along the inclined surface of the inclined plate 122 to the conveyor body 111. Finally, the conveyor body 111 is started to transport the grain, completing the unloading of the ship cabin. When the rotating rod 212 rotates, it drives the connecting rod 312 to rotate, causing the concave-convex ring 314 to rotate. When the convex position of the concave-convex ring 314 contacts the bottom of the spring extrusion ring 313, the spring extrusion ring 313 will be pushed up, accumulating rebound force. After the spring extrusion ring 313 rises and covers the special-shaped groove 317, it will squeeze the gas in the conical sleeve 311. At this time, the squeezed gas will be blocked by the blocking rod 315, so the gas pressure will increase. As the blocking rod 315 continues to move, the blocking rod 315 will separate from the exhaust pipe 316, leaving a gap between the two, and the high-pressure gas will be sprayed toward the food particles in the spiral cylinder 221 through the gap. When the convex position of the concave-convex ring 314 separates from the spring extrusion ring 313, the spring extrusion ring 313 will be pushed up, accumulating rebound force. The spring extrusion ring 313 is released to return to its original position, and the special-shaped groove 317 is connected to the top of the spring extrusion ring 313 again. The external gas enters the conical sleeve 311 through the special-shaped groove 317 to replenish the gas until the concave-convex ring 314 lifts the spring extrusion ring 313 again. This reciprocating process continuously sprays high-pressure gas to the grain particles. The high-pressure gas penetrates into the gaps between the grain particles, forming an air cushion effect, reducing the friction between the grain particles, enhancing the fluidity of the grain particles, and facilitating the conveyance of the grain particles by the spiral auger 214. It effectively prevents the poor fluidity of the grain particles from accumulating at the bottom of the spiral auger 214, causing the particles to be squeezed and easily damaged, thereby ensuring the integrity of the grain particles. Secondly, in order to solve the problem that grain particles accumulate in the cabin and the grain accumulates in a cone shape, the grain accumulated at the bottom is easy to clump, and the agglomerates have poor fluidity and are easy to cause blockage, when the spring extrusion ring 313 rises, it will drive the F-shaped rod 321 to rise. As the F-shaped rod 321 continues to move, the F-shaped rod 321 will contact the sliding frame 322, pushing the sliding frame 322 to rise, and the sliding frame 322 will push the spring block 326 and the sliding blocking rod 324 to rise, allowing the spring block 326 to accumulate rebound force. When the spring extrusion ring 313 falls, the rebound force of the spring block 326 will be released, pushing the sliding frame 322 to rise. When the movable blocking rod 324 descends, and the agglomerated grain particles are conveyed by the spiral auger 214, the larger agglomerates will be blocked by the sliding blocking rod 324 and the blocking frame 323. When the sliding blocking rod 324 rises and falls, the distance between the sliding blocking rod 324 and the blocking frame 323 changes. When the agglomerates move between the blocking frame 323 and the sliding blocking rod 324, the sliding blocking rod 324 will squeeze the agglomerates to disperse them, restore the fluidity of the grain particles, and effectively prevent the agglomerates from agglomerating. The poor fluidity of the agglomerates can easily cause the agglomerates to be blocked in the spiral drum 221, affecting the conveyance of the grain. Secondly, after the spring extrusion ring 313 rises and covers the special-shaped groove 317, external gas will enter the bottom of the spring extrusion ring 313 through the special-shaped groove 317. When the spring extrusion ring 313 is released, the spring extrusion ring 313 is lowered, which squeezes the gas at the bottom of the spring extrusion ring 313 and discharges it from the special-shaped groove 317. Since the special-shaped groove 317 has multiple complex flow channels, the flow speed of the gas is slowed down, thereby slowing down the descending speed of the spring extrusion ring 313 and the descending speed of the sliding stop rod 324, effectively preventing the rebound force of the spring block 326 from being released too quickly. The rapid descent of the sliding stop rod 324 generates a large impact force on the grain particles, causing damage to the grain particles. Secondly, when it is necessary to load the cabin, the hydraulic cylinder 114 is started to extend and push the traverse rod 115 to move, and the push rod 116 is pushed to rotate, so that the conveyor body 111 rotates, and the right side of the conveyor body 111 is raised, so that the support frame 121 rises, and the motor 3 226 is started again to rotate the support frame 121 so that the support frame 121 remains vertical, as shown in FIG. Figure 3As shown, at this time, the rebound force of the spring slide 123 is released, causing it to return to its original position, allowing the roller 124 to contact the conveyor body 111. At this time, by throwing food into the discharge hopper 112, the food falls on the conveyor body 111. By starting the conveyor body 111 to rotate in the opposite direction again, the food is transported to the feeding pipe 211. The food moves to the top of the spring slide 123 and the inclined plate 122 and is fed into the feeding pipe 211. At this time, the motor 1 213 is started to reverse the rotation rod 212 and the spiral auger 214 to transport the food downward, and the food particles will be discharged from the opening of the spiral drum 221 into the cabin. At the same time, the rotation rod 212 will also drive the concave-convex ring 314 to rotate, causing the spring extrusion ring 313 to rise, allowing the exhaust pipe 316 to spray high-pressure gas towards the descending food particles, thereby slowing down the descending speed of the food particles, effectively preventing the food particles from descending too fast and causing impact on the top of the conical sleeve 311, which may easily cause damage to the surface of the food particles and affect subsequent storage.
