Description

Technical Field

[0001] This utility model relates to the field of material feeding hopper technology, and in particular to a material feeding hopper for a grain storage silo. Background Technology

[0002] In grain storage and unloading operations, the unloading hopper of the storage silo is a key piece of equipment connecting the silo body and downstream conveying, and its operational stability directly affects the efficiency of grain unloading and the quality of storage.

[0003] Especially during the rainy season and other high-humidity environments, even if the warehouse doors are tightly closed, humid air can still seep in through the gaps and vents. As soon as you enter the warehouse, you can feel a stuffy, damp atmosphere. Every day when we check the corn, we can feel the kernels sticking together when we grab a handful. The corn that used to be perfectly dry can now be seen to have small clumps when rubbed between our hands. These corn kernels are porous and absorb moisture very quickly. Before long, they clump together into hard clumps with a diameter of several millimeters to several centimeters. When feeding the corn, we use a traditional funnel that relies on gravity to discharge the corn. These clumps of corn simply cannot go down and are all blocked at the funnel cone and the discharge port, forming layers of air gaps. Especially at the corners of the funnel and the discharge port, the damp corn sticks to the walls and, over time, forms thick clumps, making the passage narrower and narrower, and sometimes it is completely blocked. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grain storage bin discharge funnel, which solves the technical problem that corn easily clumps together in humid environments, causing blockage of the discharge funnel.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A grain storage bin discharge hopper includes a storage bin hopper with a discharge port fixedly installed at the bottom. A guide plate is fixedly installed at the lower end of the discharge port, and a column groove is formed inside the guide plate. A drive motor is fixedly installed at the lower end of the guide plate, and a rotating shaft is installed on the output end of the drive motor. The rotating shaft is rotatably installed in the column groove, and a spiral blade is fixedly installed on the rotating shaft. Crushing bars are fixedly installed at equal intervals on the rotating shaft, and power supplies are symmetrically fixedly installed on the rotating shaft. Power lines are installed on the opposite ends of the two power supplies, and both power lines are internally installed in the rotating shaft. A heating rod is connected between the two power lines and is internally installed in the rotating shaft. This discharge design ensures that the material always flows smoothly along the outlet, guaranteeing unobstructed discharge.

[0007] Preferably, a first fixing ring is fixedly installed on the feeding port, a telescopic mesh cover is fixedly installed at the lower end of the first fixing ring, a second fixing ring is fixedly installed at the lower end of the telescopic mesh cover, a first magnetic ring is fixedly installed at the lower end of the first fixing ring, and a second magnetic ring is fixedly installed at the upper end of the second fixing ring. The second magnetic ring and the first magnetic ring are magnetically connected, which facilitates easy loading and unloading and avoids the problem of large-area dust diffusion when corn is fed.

[0008] Preferably, side blocks are symmetrically fixedly installed on the side wall of the discharge port, and screws are rotatably installed inside each of the two side blocks. Both screws are in contact with the second fixing ring. Through an alternative positioning scheme, the expansion and storage of the telescopic mesh cover is more convenient, and the applicability of the equipment is enhanced.

[0009] Preferably, an internal threaded ring is rotatably installed at the lower end of the second fixing ring, and an external threaded ring is fixedly installed on the side wall of the discharge port. The internal threaded ring is threaded onto the external threaded ring. This alternative positioning scheme makes the unfolding and storage of the telescopic mesh cover more convenient and further enhances the applicability of the equipment.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The grain storage hopper's discharge hopper, through the forced pushing of spiral blades, the pre-dispersing of crushing bars, and the heating and heat transfer design of heating rods, can actively break up small-sized clumps of corn and destroy their structure. At the same time, it reduces the surface humidity of the spiral blades and crushing bars to reduce adhesion, effectively ensuring a smooth corn discharge process, avoiding local accumulation and blockage, and improving discharge efficiency and stability.

[0023] This application provides a grain storage bin discharge funnel that effectively solves the problem of corn easily clumping in humid environments, causing blockages in the discharge funnel. The grain storage bin discharge funnel, through the forced pushing of spiral blades, the pre-dispersion of crushing strips, and the heating and heat transfer design of heating rods, can actively break up small-sized clumps of corn and destroy the clumping structure. At the same time, it reduces the surface humidity of the spiral blades and crushing strips to reduce adhesion, effectively ensuring a smooth corn discharge process, avoiding local accumulation and blockage, and improving discharge efficiency and stability.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the technical solution in this application embodiment effectively solves the technical problem that corn easily clumps in a humid environment, causing blockage of the discharge hopper. The overall idea is as follows: A grain storage hopper discharge hopper includes a storage hopper 1. A discharge port 2 is fixedly installed at the bottom of the storage hopper 1. A guide plate 3 is fixedly installed at the lower end of the discharge port 2. A column groove 4 is opened inside the guide plate 3. A drive motor 5 is fixedly installed at the lower end of the guide plate 3. A rotating shaft 6 is installed on the output end of the drive motor 5. The rotating shaft 6 is rotatably installed in the column groove 4. Spiral blades 7 are fixedly installed on the rotating shaft 6. Crushing bars 8 are fixedly installed at equal intervals on the rotating shaft 6. Power supplies 9 are symmetrically fixedly installed on the rotating shaft 6. Power lines 10 are installed on the opposite ends of the two power supplies 9. Both power lines 10 are internally installed in the rotating shaft 6. A heating rod 11 is connected between the two power lines 10. The heating rod 11 is internally installed in the rotating shaft 6. When it is necessary to discharge the corn stored in the storage hopper 1, the drive motor 5 can be started. Under the action of the drive motor 5... The rotating shaft 6 will rotate, which in turn will cause the spiral blades 7 to rotate inside the feed inlet 2. The rotation of the spiral blades 7 will feed the corn inside the storage hopper 1, and the corn will fall onto the guide plates 3 and be discharged through the two guide plates 3. Through the design of the spiral blades 7, the impeller can rotate continuously or the spiral blades can push the corn to actively break up small clumps. At the same time, the continuous mechanical thrust will break up the clump structure, ensuring that the material always flows smoothly along the outlet. When the rotating shaft 6 rotates, it will drive the crushing bar 8 to rotate simultaneously. The rotation of the crushing bar 8 can pre-disperse the corn at the bottom discharge port of the heating rod 11, thereby guiding the corn to fall evenly into the feeder and avoiding local accumulation. When feeding, the power supply 9 can be turned on. At this time, the power supply 9 will power the heating rod 11 through the power cord 10, thereby heating the heating rod 11 to a temperature of 30-35℃. The heat is transferred through the rotating shaft 6 to the spiral blades 7 and the crushing bar 8 to reduce the surface humidity and further reduce adhesion.

[0025] A first fixing ring 12 is fixedly installed on the discharge port 2. A telescopic mesh cover 13 is fixedly installed on the lower end of the first fixing ring 12. A second fixing ring 14 is fixedly installed on the lower end of the telescopic mesh cover 13. A first magnetic ring 15 is fixedly installed on the lower end of the first fixing ring 12. A second magnetic ring 16 is fixedly installed on the upper end of the second fixing ring 14. The second magnetic ring 16 and the first magnetic ring 15 are magnetically connected. When discharging the material, the second magnetic ring 16 can be removed from the first magnetic ring 15 to release the magnetic attraction between them. Then, under the action of gravity, the telescopic mesh cover 13 will extend to guide the corn and avoid the problem of large-area dust diffusion when the corn is discharged.

[0026] Example 2: Figure 8As shown, side blocks 17 are symmetrically fixedly installed on the side wall of the discharge port 2. Screws 18 are rotatably installed inside both side blocks 17. Both screws 18 are in contact with the second fixing ring 14. Based on embodiment 1, this embodiment replaces the first magnetic ring 15 and the second magnetic ring 16 with side blocks 17 and screws 18. When it is necessary to unfold the telescopic mesh cover 13, the two screws 18 can be rotated on the two side blocks 17 respectively. The rotation of the two screws 18 will release the restriction on the second fixing ring 14, and then the telescopic mesh cover 13 can be extended to guide the corn.

[0027] Example 3: As Figure 9 As shown, an internal threaded ring 19 is rotatably mounted on the lower end of the second fixed ring 14, and an external threaded ring 20 is fixedly mounted on the side wall of the discharge port 2. The internal threaded ring 19 is threaded onto the external threaded ring 20. Based on embodiment 1, this embodiment replaces the first magnetic ring 15 and the second magnetic ring 16 with the internal threaded ring 19 and the external threaded ring 20. When it is necessary to unfold the telescopic mesh cover 13, the internal threaded ring 19 can be rotated on the external threaded ring 20. When the internal threaded ring 19 is separated from the external threaded ring 20, the telescopic mesh cover 13 can be extended to guide the corn.

[0028] To address the problems existing in the prior art, this utility model provides a grain storage bin discharge funnel. This grain storage bin discharge funnel, through the forced pushing of spiral blades, the pre-dispersion of crushing strips, and the heating and heat transfer design of heating rods, can actively break up small-sized clumps of corn and destroy the clump structure. At the same time, it reduces the surface humidity of the spiral blades and crushing strips to reduce adhesion, effectively ensuring a smooth corn discharge process, avoiding local accumulation and blockage, and improving discharge efficiency and stability.

[0029] Working principle:

[0030] The first step involves discharging corn stored in the storage hopper 1 by starting the drive motor 5. The drive motor 5 will then rotate the rotating shaft 6, which in turn will cause the spiral blades 7 to rotate inside the discharge port 2. The rotation of the spiral blades 7 will then discharge the corn from the storage hopper 1, causing it to fall onto the guide plates 3 and be discharged through the two guide plates 3. Through the design of the spiral blades 7, the continuous rotation of the impeller or the forced pushing of the spiral blades can actively break up small clumps, while continuous mechanical pushing... The force breaks up the agglomerated structure, ensuring that the material always flows smoothly along the outlet. When the rotating shaft 6 rotates, it will drive the crushing bar 8 to rotate synchronously. Under the rotation of the crushing bar 8, the corn at the bottom outlet of the heating rod 11 can be pre-dispersed, thereby guiding the corn to fall evenly into the feeder and avoiding local accumulation. When feeding, the power supply 9 can be turned on. At this time, the power supply 9 will power the heating rod 11 through the power cord 10, thereby heating the heating rod 11 to a temperature of 30-35℃. The heat is transferred through the rotating shaft 6 to the spiral blades 7 and the crushing bar 8 to reduce the surface humidity and further reduce adhesion.

[0031] The second step is to remove the second magnetic ring 16 from the first magnetic ring 15 when discharging the material, thereby releasing the magnetic attraction between them. Then, under the action of gravity, the telescopic mesh cover 13 will extend to guide the corn and avoid the problem of large-scale dust spread when discharging the corn.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
