Description

Technical Field

[0001] This invention relates to a device for supplying bulk materials to a conveyor, and more particularly to a bulk grain hopper for a grain terminal. Background Technology

[0002] Bulk grain hoppers used at grain terminals are key equipment for handling and transferring bulk grains, seeds, and other dry bulk materials. They play a central role in the grain storage and logistics chain, particularly in the stages of unloading grain from transport ships to warehouses or loading grain from warehouses onto transport vehicles. However, a significant drawback of traditional bulk grain hopper designs is their excessively large top opening (e.g., 7m x 7m). While this design facilitates rapid flow of bulk grain, it also exposes the hopper to rainwater intrusion when operating outdoors. Rainwater entering the hopper increases the moisture content of the grain, potentially leading to mold or rot, posing a significant threat to grain quality and food safety.

[0003] To overcome this challenge, the industry commonly uses fixed or movable iron covers or awnings to waterproof the bulk grain hoppers. While these covers or awnings largely prevent rainwater from directly entering the hoppers, they introduce new problems. First, the wide surface created when the awning is extended easily collects rainwater, causing puddles to form on its surface. Second, after severe weather, when the awning needs to be retracted, the accumulated rainwater may suddenly pour down, flowing directly into the bulk grain hopper, unexpectedly increasing the probability of the grain becoming damp and thus exacerbating the risk of grain quality damage. Summary of the Invention

[0004] In view of this, the present invention provides a bulk grain hopper for grain terminals, which can overcome the disadvantages of existing bulk grain hoppers where rainwater easily accumulates on the surface of the rain canopy to form a pond when the rain canopy is set up above it for rain protection, and when the rain canopy is taken down, the accumulated water may suddenly pour down and flow directly into the bulk grain hopper, resulting in damage to the quality of the grain.

[0005] The technical solution of the present invention is as follows: a bulk grain funnel for a grain terminal, comprising a bulk grain funnel body, a placement seat, a fixed seat, a drive motor I, a rotating seat, a telescopic tube, a cylinder, an insert rod, a support assembly, and a rainproof mechanism. The placement seat and the fixed seat are symmetrically connected to the bulk grain funnel body. The drive motor I is connected to the fixed seat. The rotating seat is rotatably connected to the fixed seat, and the rotation shaft of the rotating seat is connected to the output shaft of the drive motor I. Two telescopic tubes are respectively placed on the two placement seats, and the ends of the telescopic tubes are rotatably connected to the rotating seat. The cylinder is rotatably connected to the rotating seat, and the telescopic rod of the cylinder is rotatably connected to the bottom surface of the telescopic tube. The insert rod is connected to the end of one of the telescopic tubes, and the end of the other telescopic tube has a round hole adapted to the insert rod. The bulk grain funnel body is provided with a support assembly and a rainproof mechanism.

[0006] Furthermore, the support assembly includes a connecting seat, a winch I, and a fixing block. The connecting seat is symmetrically connected to the bulk grain hopper body, the winch I is installed on the top surface of the connecting seat, the fixing block is connected to the end of the telescopic pipe, and the end of the wire rope of the winch I is connected to the fixing block.

[0007] Furthermore, the rain-proof mechanism includes a support plate, a rotating rod, a rain-proof cloth, a drive motor II, a guide rail, a sliding rod, a pulling component, and a fixing component. The support plate is symmetrically connected to the bulk grain hopper body, the rotating rod is rotatably connected to the support plate, the rain-proof cloth is wrapped around the rotating rod, the drive motor II is connected to the bulk grain hopper body, and the end of the rotating rod is connected to the output shaft of the drive motor II. The guide rail is symmetrically connected to the bulk grain hopper body, the sliding rod is slidably connected to the guide rail, and the end of the rain-proof cloth is connected to the sliding rod. The pulling component is used to pull the sliding rod to move, and the fixing component is used to fix the position of the rain-proof cloth.

[0008] Furthermore, the pulling assembly includes a fixed plate and a winch II. The fixed plate is connected to the bulk grain hopper body, and the winch II is symmetrically connected to the fixed plate. The wire rope of the winch II slides through the side of the guide rail and is connected to the sliding rod.

[0009] Furthermore, the fixing component includes round blocks and guide plates. The round blocks are symmetrically and spaced apart on both sides of the rainproof cloth, and the guide plates are symmetrically connected to the bulk grain funnel body. The guide plates are in contact with the round blocks, and the guide rail has guide grooves and straight grooves.

[0010] Furthermore, it also includes an electric push rod I and a vertical rod. The electric push rod I is connected to one of the fixed blocks, and the vertical rod is connected to the telescopic rod of the electric push rod I. A limit groove is opened on the push rod.

[0011] Furthermore, it also includes a stabilizing component, which includes a support column I, an electric push rod II, a pressure rod I, a support column II, an electric push rod III, a pressure rod II, and a stop rod. The support column I is symmetrically connected to the top surface of the fixed plate, the electric push rod II is connected to the support column I, the pressure rod I is connected to the telescopic rod of the electric push rod II, the support column II is symmetrically connected to the bulk grain funnel body, the electric push rod III is connected to the support column II, the pressure rod II is connected to the telescopic rod of the electric push rod III, and the stop rod is connected to the top surface of the guide rail.

[0012] Furthermore, it also includes a connecting plate I, a scraper, a connecting plate II, and rollers. The connecting plate I is connected to the bulk grain funnel body, the scraper is connected to the bottom surface of the connecting plate I and the scraper is in contact with the surface of the rainproof cloth, the connecting plate II is connected to the bulk grain funnel body and the top surface of the connecting plate II is in contact with the surface of the rainproof cloth, and the rollers are rotatably connected to the side of the connecting plate I and the top surface of the connecting plate II respectively, and both rollers are in contact with the surface of the rainproof cloth.

[0013] The beneficial effects are as follows: By controlling the upward rotation of the telescopic tube, the rainproof cloth can be compressed into a four-sided pyramid shape to cover the main body of the bulk grain funnel. At the same time, the telescopic tube can drive the fixed block to move upward and straighten the wire rope of the winch I. This allows the two telescopic tubes and the wire ropes on the two winches I to act as the four edges of the aforementioned four-sided pyramid to support and stabilize the rainproof cloth, preventing rainwater from accumulating on the rainproof cloth and ensuring the quality of the grain inside the bulk grain funnel.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example: A bulk grain funnel for a grain wharf, such as... Figures 1-5 As shown, the hopper includes a bulk grain funnel body 1, a placement seat 2, a fixed seat 3, a drive motor I 4, a rotating seat 5, a telescopic tube 6, a cylinder 7, an insert rod 8, a support assembly, and a rainproof mechanism. A conveyor can be installed below the bulk grain funnel body 1. When the valve at the bottom of the bulk grain funnel body 1 is opened, the grain inside the bulk grain funnel body 1 can fall down into the conveyor, which can then transport the grain away. Placement seats 2 are connected to the left and right sides of the upper part of the bulk grain funnel body 1. The top surface of the placement seat 2 has multiple arc-shaped grooves. Fixed seats 3 are connected to the left front side and right rear side of the upper part of the bulk grain funnel body 1. There are two fixed seats 3. The drive motor I 4 is connected to the lower part of the fixed seat 3, and the rotating seat 5 is rotatably connected to the upper part of the fixed seat 3 and rotates. The lower end of the rotating shaft of seat 5 is connected to the output shaft of drive motor I4. Two telescopic tubes 6 are placed in the placement slots of two placement seats 2 respectively. The telescopic tubes 6 correspond one-to-one with the rotating seats 5, and the ends of the telescopic tubes 6 are rotatably connected to their corresponding rotating seats 5. Each telescopic tube 6 is equipped with a spring so that the telescopic tube 6 can automatically reset after extension and retraction. The sides of the two rotating seats 5 near the telescopic tubes 6 are rotatably connected to cylinders 7, and the telescopic rods of the cylinders 7 are rotatably connected to the bottom surface of the telescopic tubes 6. The rear end of the telescopic tube 6 on the left is connected to a rod 8, and the front end of the telescopic tube 6 on the right has a round hole 9 that matches the rod 8. The left side of the round hole 9 is arc-shaped, which makes it easy for the end of the rod 8 to be inserted into the round hole 9. The bulk grain funnel body 1 is equipped with a support assembly and a rainproof mechanism.

[0026] like Figure 2 As shown, the support assembly includes a connecting seat 10, a winch I 11, and a fixing block 12. The left rear side and right front side of the upper part of the bulk grain funnel body 1 are both connected to the connecting seat 10. There are two connecting seats 10. The two connecting seats 10 and the two fixing seats 3 are arranged in a rectangular shape. The winch I 11 is installed on the top surface of the connecting seat 10. The ends of the telescopic tube 6 away from the corresponding rotating seat 5 are all connected to the fixing blocks 12. There are two fixing blocks 12. The two fixing blocks 12 correspond one-to-one with the two winches I 11, and the ends of the wire ropes of the winches I 11 are fixedly connected to their corresponding fixing blocks 12.

[0027] like Figure 4 and Figure 5As shown, the rain-proof mechanism includes a support plate 13, a rotating rod 14, a rainproof cloth 15, a drive motor II 16, a guide rail 17, a sliding rod 18, a pulling assembly, and a fixing assembly. Support plates 13 are symmetrically connected to the upper rear side of the bulk grain funnel body 1. A rotating rod 14 is rotatably connected between the upper parts of the two support plates 13. The rainproof cloth 15 is wrapped around the rotating rod 14. The drive motor II 16 is connected to the upper right rear side of the bulk grain funnel body 1, and the right end of the rotating rod 14 is connected to the output shaft of the drive motor II 16. The upper part of the hopper body 1 is symmetrically connected with guide rails 17. The front end of the guide rails 17 is curved downwards. A sliding rod 18 is slidably connected between the two guide rails 17. The sliding rod 18 is in the shape of an inverted U. The end of the rainproof cloth 15 away from the rotating rod 14 is connected to the rear side of the sliding rod 18. The pulling component is used to pull the sliding rod 18 to move, and the fixing component is used to fix the position of the rainproof cloth 15. The pulling component includes a fixing plate 19 and a winch II 20. The fixing plate 19 is connected to the upper part of the bulk grain hopper body 1. On the front side, the front end of the guide rail 17 is fixedly connected to the top surface of the fixed plate 19. Winches II 20 are symmetrically connected to the bottom surface of the fixed plate 19. Winches II 20 correspond one-to-one with guide rails 17. The wire rope of winch II 20 slides through the front side of its corresponding guide rail 17, and the end of the wire rope of winch II 20 is connected to the front side of the sliding rod 18. The fixing assembly includes round blocks 21 and guide plates 22. Multiple round blocks 21 are spaced apart on both sides of the rainproof cloth 15. The left and right sides of the upper rear side of the bulk grain funnel body 1... Each guide rail 15 is connected to two guide plates 22. The rear side of each guide rail 17 has a guide groove 23, and the middle of each guide rail 17 has a slot 24. When the rain cover 15 is pulled forward and unfolded, the round block 21 can pass between the two guide plates 22. Through the squeezing and guiding of the two guide plates 22, the round block 21 can rotate from a vertical state to a horizontal state and slide into the slot 24 through the guide groove 23. The slot 24 can limit the round block 21, thereby fixing the left and right sides of the rain cover 15.

[0028] When in use, the bulk grain funnel body 1 can be used for temporary storage of grain. Simultaneously, the lower valve of the bulk grain funnel body 1 can be opened, allowing the grain inside to fall down its inner wall onto a conveyor for transport. When the bulk grain funnel body 1 is not in use or during rainy weather, the drive motor II 16 can be controlled to drive the rotating rod 14 to release the rain cover 15. Simultaneously, the winch II 20 can be controlled to wind up the wire rope, thereby pulling the sliding rod 18 forward along the guide rail 17. The sliding rod 18 pulls the front end of the rain cover 15 forward, causing the rain cover 15 to unfold and block the top of the bulk grain funnel body 1. At this time, the rain cover 15 can drive the circular block 21 on it to move forward. The circular block 21 will pass through two guide plates 22. During this process, the two guide plates 22 can guide the round block 21 and squeeze the round block 21 to rotate from a vertical state to a horizontal state. Then, the round block 21 will slide into the straight groove 24 through the guide groove 23 and move forward along the straight groove 24. At this time, the straight groove 24 can limit the round block 21 in the vertical direction, so as to prevent gaps from appearing between the left and right sides of the rainproof cloth 15 and the top surface of the bulk grain funnel body 1. Since the front end of the guide rail 17 is curved downward, the sliding rod 18 can eventually rotate from a vertical state to a horizontal state along the front end of the guide rail 17, so that the side of the sliding rod 18 contacts the top surface of the fixed plate 19, thereby preventing gaps from appearing between the front side of the rainproof cloth 15 and the top surface of the bulk grain funnel body 1, thus ensuring that the rainproof cloth 15 has a good rainproof effect.Subsequently, the rotating base 5 can be driven to rotate horizontally by the drive motor I4 by 45 degrees. The rotating base 5 can drive the telescopic tubes 6 on the left and right sides to rotate horizontally by 45 degrees. Since the telescopic tubes 6 on the left and right sides are diagonally arranged, the ends of the telescopic tubes 6 on the left and right sides that are away from the rotating base 5 will gradually move closer. At the same time, the ends of the telescopic tubes 6 on the left and right sides that are away from the rotating base 5 will drive the two fixed blocks 12 to gradually move closer. Simultaneously, the winch I11 can be controlled to release the wire rope on it, so as not to affect the movement of the fixed blocks 12, until the ends of the telescopic tubes 6 on the left and right sides that are away from the rotating base 5 have moved to the center point above the bulk grain funnel body 1, and the insertion rod 8 can be accurately inserted into the round Inside hole 9, because a spring is installed inside telescopic tube 6, even if there is a small error when inserting rod 8 is aligned with round hole 9, the right end of inserting rod 8 will contact the arc surface on the left side of round hole 9. Under the squeezing and guiding action of the arc surface, telescopic tube 6 can slightly extend and retract to assist inserting rod 8 in accurately inserting into round hole 9. This completes the docking of two telescopic tubes 6. Then, the telescopic rod of cylinder 7 is extended, and cylinder 7 can drive the telescopic tubes 6 on both sides to rotate upward around rotating seat 5. The ends of the telescopic tubes 6 on both sides away from rotating seat 5 will also drive the two fixed blocks 12 to move upward (the wire rope on winch I 11 is always taut). This allows the center of the unfolded portion of the rainproof cloth 15 to be lifted upwards. The rainproof cloth 15 has a certain degree of elasticity, and at this time, the unfolded portion of the rainproof cloth 15 can cover the bulk grain funnel body 1 in the shape of a four-sided pyramid. The steel wire ropes on the two telescopic pipes 6 and the two winches I11 act as the four edges of the pyramid, allowing rainwater to slide down along the top surface of the rainproof cloth 15 and preventing rainwater accumulation on it. After the rain stops, the telescopic rod of the cylinder 7 can be shortened, and the cylinder 7 can drive the telescopic pipes 6 on both sides to rotate downwards around the rotating seat 5 to reset. The ends of the telescopic pipes 6 on both sides away from the rotating seat 5 will... The two fixed blocks 12 move downwards to reset, allowing the unfolded part of the rainproof cloth 15 to recover due to gravity and its own elasticity. Then, the drive motor I4 drives the rotating seat 5 to rotate horizontally by 45 degrees to reset. The rotating seat 5 can drive the telescopic tubes 6 on both sides to rotate horizontally by 45 degrees back to the placement seat 2, separating the insertion rod 8 from the round hole 9. At the same time, the winch I11 can be controlled to rewind and reset the steel wire rope on it. Finally, the winch II20 is controlled to loosen the steel wire rope on it, and the drive motor II16 is controlled to drive the rotating rod 14 to rotate in reverse to rewind the rainproof cloth 15, which can pull the sliding rod 18 to move backwards along the guide rail 17 to reset.

[0029] like Figure 6As shown, it also includes an electric push rod I 25 and a vertical rod 26. The electric push rod I 25 is connected to the fixing block 12 on the right side. The vertical rod 26 is connected to the telescopic rod of the electric push rod I 25. The insertion rod 8 has a limiting groove 27. When the insertion rod 8 is inserted into the round hole 9, the limiting groove 27 is located directly below the vertical rod 26. At this time, the electric push rod I 25 can drive the vertical rod 26 to move downward, so that the lower end of the vertical rod 26 extends into the limiting groove 27, thereby preventing the insertion rod 8 from detaching from the round hole 9 and ensuring the stability of the rainproof cloth 15 after it unfolds into a four-sided pyramid shape.

[0030] like Figure 7 and Figure 8 As shown, it also includes a stabilizing assembly, which includes support column I 28, electric push rod II 29, pressure rod I 30, support column II 31, electric push rod III 32, pressure rod II 33, and a stop rod 34. Two support columns I 28 are connected to the left and right sides of the top surface of the fixing plate 19. The electric push rod II 29 is connected to the support column I 28 and is inclined. A pressure rod I 30 connects the telescopic rods of the two electric push rods II 29. Four support columns II 31 are connected to the upper left and right sides of the bulk grain funnel body 1 at intervals. Electric push rods III 32 are connected to the support column II 31 and are also inclined. A pressure rod connects the telescopic rods of the four electric push rods III 32. II33 and the abutment rod 34 are connected to the top surface of the guide rail 17. The abutment rod 34 has a groove on its side near the pressure rod II33 so that when the telescopic rod of the electric push rod III32 is extended, it can drive the pressure rod II33 to move into the groove of the abutment rod 34. When the rain cover 15 is unfolded into a four-sided pyramid shape, the electric push rod II29 can be controlled to drive the pressure rod I30 to move diagonally downward, so that the pressure rod I30 presses against the top surface of the sliding rod 18. At the same time, the electric push rod III32 can be controlled to drive the pressure rod II33 to move diagonally downward until it contacts the abutment rod 34. The pressure rod II33 and the abutment rod 34 cooperate to clamp the left and right sides of the rain cover 15, which can further stabilize the position of the rain cover 15 and prevent the rain cover 15 from being blown over by strong winds.

[0031] like Figure 9As shown, it also includes a connecting plate I 35, a scraper 36, a connecting plate II 37, and rollers 38. The connecting plate I 35 is connected to the upper rear side of the bulk grain funnel body 1. The scraper 36 is connected to the bottom surface of the connecting plate I 35 and contacts the top surface of the rainproof cloth 15. The connecting plate II 37 is connected to the upper rear side of the bulk grain funnel body 1. The connecting plate II 37 is located in front of and below the connecting plate I 35, and the top surface of the connecting plate II 37 contacts the bottom surface of the rainproof cloth 15. The upper part of the connecting plate II 37 has a Y-shaped opening. Rollers 38 are rotatably connected to the front right side of the connecting plate I 35 and the upper left side of the connecting plate II 37. The right roller 38 presses against the right side of the top surface of the rainproof cloth 15, and the left roller 38 abuts against the rainproof cloth 15. On the left side of the bottom surface of the tarpaulin 15, both rollers 38 are located in the opening at the top of the connecting plate II 37. When the rotating rod 14 is reversing to roll up the tarpaulin 15, since a small amount of rainwater will inevitably remain on the top surface of the tarpaulin 15, under the support of the connecting plate II 37, the top surface of the tarpaulin 15 will pass under the scraper 36 and stick to the bottom surface of the scraper 36. Therefore, the scraper 36 can scrape off the rainwater adhering to the top surface of the tarpaulin 15. At the same time, under the squeezing action of the two rollers 38, the part of the tarpaulin 15 below the scraper 36 can be in a state of left-high and right-low. The rainwater scraped off by the scraper 36 can slide down to the right along the top surface of the tarpaulin 15, which can prevent rainwater from entering the bulk grain funnel body 1.

[0032] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
