Description

Technical Field

[0001] This invention relates to the field of grain conveying technology, and in particular to a grain conveying and unloading device. Background Technology

[0002] Grains encompass a wide range, including rice, wheat, millet, soybeans, and other miscellaneous grains, primarily plant seeds and fruits. Currently, existing grain silos are generally constructed of concrete or welded steel plates. To increase grain storage capacity, grain silos are taking up increasingly larger areas, which presents challenges when transporting grain to them. Due to the large area of ​​the silos, grain needs to be constantly moved inside to fill them. The current method typically involves driving transport vehicles directly into the silo, then manually or with a forklift to spread the grain. However, since the forklift needs to rotate inside the silo, this takes too much time and reduces work efficiency.

[0003] Furthermore, in most grain silos, grain is typically transported from the top to the silo during storage. Some methods involve installing conveyors on the top of the silo, which are manually controlled. Since it's inconvenient to observe the transport process within the silo, personnel must constantly monitor the situation, consuming significant time and reducing efficiency. Alternatively, sensors can be installed on the silo or conveyor to assess the grain transport status. However, the large amount of dust generated during transport can interfere with sensor readings, further hindering efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a grain conveying and unloading device to solve the problem of low working efficiency in existing grain conveying methods.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A grain conveying and unloading device includes:

[0007] The grain silo has a conveyor for transporting grain on one side of its top. The conveyor has multiple discharge ports for discharging grain, and the top surface of the grain silo has multiple inlets for entering grain distributed in a grid pattern. A conveying mechanism spans across the top of the grain silo and slides back and forth on the top of the grain silo. Grain discharged from each of the discharge ports is discharged into the grain silo from the inlets through the conveying mechanism.

[0008] A pneumatic mechanism is fixedly installed on the conveying mechanism, which blows the grain in the conveying mechanism from the feed inlet into the grain silo; a discharge mechanism is fixedly installed at the bottom of the conveying mechanism, through which the grain is discharged from the feed inlet into the grain silo; an opening and closing mechanism is fixedly installed at each feed inlet to control the opening and closing of the feed inlet.

[0009] Furthermore, the conveying mechanism includes a truss spanning the top of the grain silo, a conveying channel fixedly installed on the truss for conveying grain, and an auger rotatably installed in the conveying channel. The discharge mechanism and the pneumatic mechanism are respectively connected and installed at the bottom and top of the conveying channel.

[0010] Furthermore, the discharge mechanism includes a discharge cylinder fixedly installed at the bottom of the conveying channel, a sleeve lifted and lowered inside the discharge cylinder, and a lifting component lifted and lowered inside the sleeve. A baffle is arranged in a ring inside the sleeve, and the lifting component stops discharging after rising to abut against the baffle.

[0012] Furthermore, the lifting component is connected to a material pipe for grain flow, the top of the baffle is set as an inclined surface, and a roller is rotatably mounted on the lifting component, the roller rolling vertically along the inner side wall of the sleeve.

[0013] A first stop is fixedly provided on the inner side wall of the discharge cylinder, and a second stop is fixedly provided on the inner side wall of the sleeve, which is opposite to the first stop. A groove adapted to the first stop is opened on the top of the sleeve. The discharge stops when the second stop rises to coincide with the first stop.

[0014] Furthermore, the lifting component includes a top plate and a bottom plate that are lifted and lowered within the sleeve, and a support column that is fixedly disposed between the top plate and the bottom plate. The top plate rises and abuts against the baffle. A conical groove for grain to pass through is provided vertically through the top plate. The top of the material pipe and the bottom of the conical groove are connected. The bottom of the material pipe is rotatably disposed on the bottom plate.

[0015] Furthermore, a fastener is rotatably mounted on the base plate, and an elbow for discharging grain is fixedly mounted on the fastener. The elbow is connected to the feed pipe and bends toward the central axis of the base plate. A conical block to assist the grain in falling is mounted on the central axis of the top plate.

[0016] Furthermore, the fastener includes a fixing block fixedly mounted on the base plate, a connecting rod rotatably mounted on the fixing block, and a knob screwed onto the fixing block. The fixing block and the connecting rod are respectively provided with protrusions, and the two protrusions are engaged. The knob and the fixing block clamp the connecting rod, and the elbow is fixedly connected to the connecting rod.

[0017] The bottom of the sleeve is bent inward and a support block is provided, and a spring is provided between the support block and the top plate.

[0018] Furthermore, the pneumatic mechanism includes a fan fixedly mounted on the top of the truss and joints arranged on the conveying channel. The joints and the fan are connected by a duct, and the joints are inclined.

[0019] Furthermore, the opening and closing mechanism includes a support frame fixedly mounted on the grain silo, a second drive cylinder rotatably mounted on the support frame, a swing rod rotatably mounted on the support frame, and a cover fixedly mounted on the swing rod, wherein the cover coincides with the feed inlet;

[0020] The second drive cylinder has a first transmission rod and a second transmission rod rotatably mounted on its drive rod. The first transmission rod is rotatably mounted on the swing rod, and the second transmission rod is rotatably mounted on the support frame.

[0021] Furthermore, the top of the grain silo is covered with a track for the conveying mechanism to move, and a guide wheel assembly is rotatably mounted on the conveying mechanism, the guide wheel assembly being driven by a motor;

[0022] The tracks are arranged in at least two sets, and the guide wheel sets are arranged in at least four sets, which are arranged opposite to each other at both ends of the conveying mechanism.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The grain conveying and unloading device of this invention uses a conveying mechanism that spans across the top of the grain silo to ensure that grain can be conveyed to every position inside the silo, reducing the need for manual spreading of grain inside the silo. A pneumatic mechanism ensures that any grain remaining in the conveying mechanism is blown into the silo, preventing spoilage. A discharge mechanism ensures that material can only be discharged after it extends into the silo, and automatically stops discharging when the silo is full. An opening and closing mechanism works in conjunction with the discharge mechanism to ensure the silo's inlet is sealed, preventing water leakage and grain spoilage.

[0025] Furthermore, the coordinated design of the feed pipe and elbows ensures that the grain can be conveyed to the bottom of the base plate. As the grain pile grows higher, it can lift the lifting component, thereby stopping the discharge. The spring design ensures that when there is no grain in the conveying pipe, the spring drives the lifting component to lift, which can also stop the discharge and facilitates movement to the next feed inlet. The fasteners ensure that the elbow can be adjusted in angle, thereby controlling the position of the grain conveying. The conical groove design prevents grain residue on the top plate from affecting the contact between the top plate and the baffle. The rollers assist in the lifting of the lifting component, reduce friction, and ensure that the grain can lift the lifting component. Attached Figure Description

[0052] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0053] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "back" appear, indicating orientation or positional relationship, these are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0055] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] This embodiment relates to a grain conveying and unloading device, the overall structure of which is as follows: Figure 1 and Figure 2 As shown, it includes a grain bin 1, a conveying mechanism 5, a pneumatic mechanism 6, a discharge mechanism 7, and an opening and closing mechanism 8.

[0057] The grain silo 1 has a conveyor 2 for transporting grain on one side of its top. The conveyor 2 has multiple discharge ports 3 for discharging grain. The top surface of the grain silo 1 has multiple feed ports 4 for entering grain. The conveying mechanism 5 spans the top of the grain silo 1 and slides back and forth on the top of the grain silo 1. Grain discharged from each discharge port 3 is discharged into the grain silo 1 through the feed port 4 via the conveying mechanism 5. The pneumatic mechanism 6 is fixedly installed on the conveying mechanism 5. The pneumatic mechanism 6 blows the grain in the conveying mechanism 5 to be discharged into the grain silo 1 through the feed port 4. The discharge mechanism 7 is fixedly installed at the bottom of the conveying mechanism 5. Grain is discharged into the grain silo 1 through the discharge mechanism 7 from the feed port 4. The opening and closing mechanism 8 is fixedly installed at each feed port 4 to control the opening and closing of the feed port 4.

[0058] It is worth mentioning that in this embodiment, the grain silo 1 is a rectangular grain silo 1, which facilitates the reciprocating sliding of the conveying mechanism 5 on the top of the grain silo 1. The conveyor 2 can be a scraper conveyor 2, which is located on one side of the top of the grain silo 1. Multiple discharge ports 3 are arranged along the length of the conveyor 2. When the conveying mechanism 5 moves to each discharge port 3, the grain can enter the conveying mechanism 5 from the discharge port 3. Then, each discharge mechanism 7 discharges the grain from each inlet 4 into the grain silo 1. That is to say, each discharge mechanism 7 and each inlet 4 are connected. The discharge port 3 and feed port 4 overlap, so that the grain discharged from the discharge port 3 can be transported to the feed port 4 through the conveying mechanism 5. A valve can be installed at the discharge port 3 of the conveyor 2 to facilitate control of whether the discharge port 3 discharges. Multiple sets of discharge mechanisms 7 are set and arranged along the length of the conveying mechanism 5. Therefore, the grid-distributed feed ports 4 can ensure that multiple sets of discharge mechanisms 7 and each row of feed ports 4 overlap. The pneumatic mechanism 6 is connected to the conveying mechanism 5. If there is residual grain in the conveyor 2, the pneumatic mechanism 6 can blow the residual grain into the grain bin 1. The opening and closing mechanism 8 can flip at the feed port 4. When the discharge mechanism 7 moves to the feed port 4, the opening and closing mechanism 8 opens and the discharge mechanism 7 extends into the feed port 4 to discharge.

[0059] Based on the above overall introduction, this embodiment presents an exemplary structure of the grain conveying and unloading device, such as... Figure 2 , Figure 3 and Figure 5 As shown, the conveying mechanism 5 includes a truss 501 spanning the top of the grain silo 1, a conveying channel 502 fixedly mounted on the truss 501 for conveying grain, and an auger 503 rotatably mounted within the conveying channel 502. A discharge mechanism 7 and a pneumatic mechanism 6 are respectively connected to the bottom and top of the conveying channel 502. A track 9 for the conveying mechanism 5 to move is laid on the top of the grain silo 1. A guide wheel assembly 10 is rotatably mounted on the conveying mechanism 5. The guide wheel assembly 10 is driven by a motor. At least two sets of tracks 9 are arranged opposite each other, and at least four sets of guide wheel assemblies 10 are arranged opposite each other at both ends of the conveying mechanism 5.

[0060] It should be noted that, in order to facilitate the movement of the conveying mechanism 5, two trusses 501 are arranged opposite each other on the top of the grain bin 1 in this embodiment. Four sets of guide wheels 10 are respectively arranged at both ends of the length direction of the truss 501 and are arranged opposite each other, which can drive the truss 501 to move. The four sets of guide wheels 10 slide back and forth along the track 9. Motors are installed on the guide wheels 10 at both ends of the truss 501, and the truss 501 is driven to move by the motors, ensuring that the truss 501 remains parallel when moving. The conveying channel 502 is along the truss 501. 1. Lay along the length direction, the auger 503 rotates in the conveying channel 502, the auger 503 drives the grain to be discharged from each discharge mechanism 7, the central shaft of the auger 503 extends from the conveying channel 502, a motor is installed on the conveying channel 502, the motor and the central shaft of the auger 503 are fixedly connected, the motor can drive the auger 503 to rotate, the pneumatic mechanism 6 is fixedly installed on the truss 501, which is convenient to connect with the conveying channel 502, and the discharge mechanism 7 is installed at the bottom of the conveying channel 502, which is convenient to discharge the grain from the discharge mechanism 7.

[0061] To facilitate the discharge of grain from the conveyor channel 502 into the grain silo 1, preferably, as follows: Figure 7 , Figure 8 and Figure 10 As shown, the discharge mechanism 7 includes a discharge cylinder 701 fixedly installed at the bottom of the conveying channel 502, a sleeve 702 lifted and lowered inside the discharge cylinder 701, and a lifting member 703 lifted and lowered inside the sleeve 702. A baffle 704 is arranged in a ring inside the sleeve 702. The lifting member 703 stops discharging after rising to abut against the baffle 704. A guide rod 705 is fixedly installed on the outer wall of the sleeve 702. The guide rod 705 is slidably installed on the outer wall of the discharge cylinder 701. A linear bearing 706 is fixedly installed on the outer wall of the discharge cylinder 701. The guide rod 705 is slidably installed inside the linear bearing 706. A first drive cylinder 707 is fixedly installed on the discharge cylinder 701 to drive the sleeve 702 to rise and fall.

[0062] It should be noted that the top of the discharge cylinder 701 is fixedly installed at the bottom of the conveying channel 502. An opening is provided at the bottom of the conveying channel 502, and the discharge cylinder 701 is installed at this opening. Grain is discharged through the discharge cylinder 701 from the opening. The sleeve 702 moves up and down within the discharge cylinder 701. When the sleeve 702 descends, it extends into the grain bin 1 from the inlet 4 for discharge. When the sleeve 702 rises, it retracts from the inlet 4, facilitating the movement of the conveying mechanism 5. A baffle 704 is installed along the inner wall of the sleeve 702. After the lifting component 703 rises, it contacts the baffle 704. At this time, the lifting component 703 and the baffle 704 block the sleeve 702, stopping the discharge. When grain enters the sleeve 702 from the discharge cylinder 701, due to gravity, the grain falls behind the lifting component 703 and... The lifting component 703 is pushed down, and then the grain is discharged from the lifting component 703, thereby realizing the discharge. The guide rod 705 and the linear guide rail can improve the stability of the lifting of the sleeve 702. A fixing plate can be welded to the outer wall of the sleeve 702, and the guide rod 705 can be installed on the fixing plate. A fixing plate is also set on the discharge cylinder 701. The linear bearing 706 passes through the fixing plate, and the guide rod 705 passes through the linear bearing 706 to ensure that the sleeve 702 can only perform lifting and lowering movements. The cylinder body of the first drive cylinder 707 is fixedly installed on the sleeve 702, and the drive rod of the first drive cylinder 707 is fixedly installed on the sleeve 702. The extension and retraction of the drive rod of the first drive cylinder 707 can drive the sleeve 702 to lift and lower, thereby realizing the feeding of material from the conveying channel 502 to the feed port 4.

[0063] To ensure the smoothness of the lifting component 703 during lifting, as a preferred embodiment, such as Figure 11 and Figure 12 As shown, in this embodiment, a feed pipe 708 for grain flow is connected to the lifting component 703. The top of the baffle 704 is set as an inclined surface. Rollers 709 are rotatably mounted on the lifting component 703, and the rollers 709 roll vertically along the inner wall of the sleeve 702. Specifically, the top of the feed pipe 708 is installed on the upper part of the lifting component 703 and is connected to the lifting component 703. When the grain falls into the lifting component 703, it is discharged from the feed pipe into the grain bin 1. A column can be vertically mounted on the lifting component 703, and two rollers 709 are rotatably mounted on the column. The two rollers 709 are vertically mounted and roll along the inner wall of the sleeve 702 to ensure the smoothness of the lifting component 703 during lifting and lowering and reduce friction.

[0064] To ensure that the discharge mechanism 7 does not discharge material while the conveyor mechanism 5 is moving, as a preferred embodiment, such as Figure 9 and Figure 10As shown, in this embodiment, a first stop 714 is fixedly provided on the inner wall of the discharge cylinder 701, and a second stop 715 opposite to the first stop 714 is fixedly provided on the inner wall of the sleeve 702. A groove 716 adapted to the first stop 714 is provided on the top of the sleeve 702. Discharge stops when the second stop 715 rises to overlap with the first stop 714. Specifically, the first stop 714 occupies half of the circular cross-section of the discharge cylinder 701, and the second baffle 704 occupies half of the circular cross-section of the sleeve 702. The first stop 714 and the second stop 715 are arranged opposite to each other. When the first drive cylinder 707 drives the sleeve 702 to rise, the groove 716 on the sleeve 702 inserts into the first stop 714, from... Figure 9 It can be seen that at this time, the first stop 714 and the second stop 715 are parallel, which can prevent the grain from being discharged from the sleeve 702. The sleeve 702 rises and comes out from the feed port 4, which facilitates the movement of the conveying mechanism 5 and can also prevent the material from being discharged. When the first drive cylinder 707 drives the sleeve 702 to descend, the first stop 714 and the second stop 715 separate. The first stop 714 and the second stop 715 are set as inclined surfaces, which can avoid residual grain. The grain falls from the first stop 714 to the second stop 715 in sequence, and then is discharged from the lifting component 703.

[0065] To ensure that the grain is discharged from the lifting component 703, preferably, as follows: Figure 12 and Figure 13 As shown, in this embodiment, the lifting component 703 includes a top plate 7031 and a bottom plate 7032 that are lifted and lowered within the sleeve 702, and a support column 7033 that is fixedly disposed between the top plate 7031 and the bottom plate 7032. The top plate 7031 rises and abuts against the baffle 704. The top plate 7031 is provided with a conical groove 7034 that allows grains to pass through. The top of the material pipe 708 is connected to the bottom of the conical groove 7034. The bottom of the material pipe 708 is rotatably disposed on the bottom plate 7032.

[0066] It should be noted that the top plate 7031 and the bottom plate 7032 are arranged in parallel. The support column 7033 is used to support the top plate 7031 and the bottom plate 7032. The material pipe 708 is located between the top plate 7031 and the bottom plate 7032. After the top plate 7031 and the baffle 704 abut, the conical groove 7034 is covered by the baffle 704, thus stopping the discharge. The baffle 704 is set as an inclined surface to avoid residual grain. The conical groove 7034 is also set to avoid residual grain on the top plate 7031. When the top plate 7031... As the grain descends, it falls from the baffle 704 onto the top plate 7031. The conical groove 7034 on the top plate 7031 discharges the grain into the feed pipe 708, and then from the feed pipe 708 into the grain bin 1. The bottom of the feed pipe 708 is installed on the bottom plate 7032 to ensure that the grain discharged from the feed pipe 708 falls on the lower part of the bottom plate 7032. As the grain gradually rises in the grain bin 1, it can lift the bottom plate 7032. At the same time, the roller 709 rotates, causing the top plate 7031 and the baffle 704 to come into contact. After contact, the discharge stops.

[0067] To ensure that the grains fall under the bottom plate 7032, as a preferred embodiment, such as Figure 11 As shown, in this embodiment, a fastener 710 is rotatably provided on the base plate 7032, and an elbow 711 for discharging grain is fixedly provided on the fastener 710. The elbow 711 is connected to the feed pipe 708, and the elbow 711 bends toward the central axis of the base plate 7032. A conical block 717 for assisting grain to fall is provided on the central axis of the top plate 7031. Specifically, fastener 710 fixes elbow 711 to base plate 7032. Grain discharged from feed pipe 708 is discharged into grain bin 1 through elbow 711. The purpose of elbow 711 bending towards the central axis of base plate 7032 is to ensure that grain falls into the lower part of base plate 7032. The conical block 717 is set to prevent grain from being stuck on top plate 7031 when it is flat. The conical block 717 ensures that grain flows into conical groove 7034. Therefore, the conical block 717 can prevent grain from remaining on top plate 7031. Fastener 710 can also adjust the angle of elbow 711 to ensure that elbow 711 is fixed in a certain position, thereby achieving different angles of elbow 711 towards the central axis of base plate 7032.

[0068] To enable the elbow 711 to be angle-adjustable, as a preferred embodiment, such as... Figure 14As shown, in this embodiment, the fastener 710 includes a fixing block 7101 fixedly mounted on the base plate 7032, a connecting rod 7102 rotatably mounted on the fixing block 7101, and a knob 7103 screwed onto the fixing block 7101. The fixing block 7101 and the connecting rod 7102 are respectively provided with protrusions 7104, and the two protrusions 7104 are engaged. The knob 7103 and the fixing block 7101 clamp the connecting rod 7102. The elbow 711 is fixedly connected to the connecting rod 7102. The bottom of the sleeve 702 is bent inward to provide a support block 712. A spring 713 is provided between the support block 712 and the top plate 7031.

[0069] It should be noted that the fixing block 7101 can be welded to the edge of the base plate 7032. The connecting rod 7102 rotates on the fixing block 7101, and the elbow 711 is mounted on the connecting rod 7102. When the connecting rod 7102 rotates, it can drive the elbow 711 to rotate. When it is necessary to fix the elbow 711, simply turn the knob 7103. Because the knob 7103 passes through the connecting rod 7102 and is screwed to the fixing block 7101, turning the knob 7103 can clamp the connecting rod 7102 onto the fixing block 7101. In order to improve the friction between the connecting rod 7102 and the fixing block 7101, corrugated protrusions 7104 are provided on the circumference of the connecting rod 7102 and the fixing block 7101. The engagement of the protrusions 7104 can ensure that the elbow 711 will not rotate after being fixed, thus improving stability. In addition, from Figure 12 As can be seen, the support block 712 is located at the bottom of the inner wall of the sleeve 702, and the spring 713 is used to support the top plate 7031. When there is no grain in the sleeve 702, the spring 713 can support the lifting component 703 to rise, so as to avoid the conveying mechanism 5 from being affected when it moves. The spring 713 can be installed with different spring coefficients or not installed at all, depending on the actual situation, because it needs to be controlled according to the amount of grain conveyed. The purpose is to ensure that the spring 713 can be compressed when the grain falls, that is, the lifting component 703 can descend.

[0070] To ensure that no grain remains in the conveying channel 502, preferably, as follows: Figure 6 As shown, in this embodiment, the pneumatic mechanism 6 includes a fan 601 fixedly mounted on the top of the truss 501 and connectors 602 arranged on the conveying channel 502. The connectors 602 and the fan 601 are connected by an air duct 603, and the connectors 602 are inclined.

The connectors 602 are inserted through the top of the conveying channel 502, and the inclined direction of the connectors 602 is also towards the end away from the inlet, ensuring that the airflow direction is the same as the conveying direction of the auger 503. Multiple connectors 602 are arranged to improve the blowing efficiency. The multiple connectors 602 are connected by the air duct 603 to ensure that the fan 601 can deliver airflow to each connector 602.

[0071] To ensure the sealing effect of the grain silo 1 and facilitate the insertion of the discharge mechanism 7 into the inlet 4, preferably, as follows: Figure 4 As shown, in this embodiment, the opening and closing mechanism 8 includes a support frame 801 fixedly mounted on the grain silo 1, a second drive cylinder 802 rotatably mounted on the support frame 801, a swing rod 803 rotatably mounted on the support frame 801, and a cover 804 fixedly mounted on the swing rod 803. The cover 804 coincides with the feed inlet 4. A first transmission rod 805 and a second transmission rod 806 are rotatably mounted on the drive rod of the second drive cylinder 802. The first transmission rod 805 is rotatably mounted on the swing rod 803, and the second transmission rod 806 is rotatably mounted on the support frame 801.

[0072] It should be noted that the support frame 801 is located on one side of the feed inlet 4. The cylinder body of the second drive cylinder 802 is rotatably connected to the support frame 801. The first drive cylinder 707 and the second drive cylinder 802 can be hydraulic cylinders for easy control. The cover 804 rotates with the swing rod 803. When it rotates to a vertical position, the feed inlet 4 is opened. The opposite rotation closes the feed inlet 4. The two ends of the second transmission rod 806 are connected to the drive rod shafts of the swing rod 803 and the second drive cylinder 802, respectively. When the drive rod of the second drive cylinder 802 retracts, the second transmission rod 806 can pull the swing rod 803 to rotate upward, thereby opening the feed inlet 4. The two ends of the first transmission rod 805 are connected to the drive rod of the second drive cylinder 802 and the shaft of the support frame 801. When the second transmission rod 806 pulls the swing rod 803 to rotate, the first transmission rod 805 rotates accordingly, which can improve the stability of the swing rod 803 during rotation and avoid dead points that could cause jamming.

[0073] In this embodiment, the grain conveying and feeding device spans the top of the grain silo 1 via a conveying mechanism 5, ensuring that grain can be conveyed to every location within the grain silo 1, reducing the need for manual spreading of grain within the grain silo 1. The pneumatic mechanism 6 ensures that any remaining grain within the conveying mechanism 5 can be blown into the grain silo 1, preventing spoilage of the grain remaining in the conveying mechanism 5. The discharge mechanism 7 ensures that material can only be discharged after it extends into the grain silo 1, and automatically stops discharging once the grain silo 1 is full. The opening and closing mechanism 8 works in conjunction with the discharge mechanism 7 to open and close, ensuring that the inlet 4 of the grain silo 1 is sealed, preventing water leakage and spoilage of the grain within the grain silo 1.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
