Description

Technical Field

[0001] This invention relates to the field of warehouse unloading technology, specifically to a suspended arch-breaking unloading machine for flat warehouses. Background Technology

[0002] A flat warehouse is a type of warehouse used for storing materials. The storage yard of a flat warehouse is rectangular, with a width that is often 30 to 40 meters and a depth that can sometimes reach more than 200 meters. Several trenches are set at the bottom of the flat warehouse, and gates are set at the top of the trenches. Conveyor belts are installed in the trenches. The gates at the top of the trenches are normally closed. When materials need to be discharged, the gates will open, and the discharge machine will move the materials at the bottom of the storage yard into the trenches. The auxiliary materials will flow into the trenches, and after the materials fall onto the conveyor belt, the materials will be discharged using the conveyor belt in the trenches.

[0003] When it is necessary to output highly caking materials such as soybean meal stored in flat warehouses, the materials become severely caking and lose their fluidity after being piled up. After the ordinary warehouse discharge machine transports the material horizontally at the bottom into the trough, the warehouse discharge machine will dig out a cavity at the bottom of the material, and the rest of the material will remain in a caking state.

[0004] To solve the above problems, the prior art, such as the arch-breaking and unloading machine, arch-breaking and unloading system and arch-breaking and unloading method disclosed in Chinese Patent Application No. 202310166651.7, proposes an unloading machine and an arch-breaking structure that can first break the arches of the accumulated materials, making the hardened materials flowable, and then use the unloading machine to move the flowable materials into the trench.

[0005] However, the above method has drawbacks. Its arch-breaking structure cannot completely break up all the materials in the warehouse because it extends to the bottom of the discharge machine. It only breaks up the materials near the discharge machine. However, due to the high height of the material pile in the flat warehouse, the arch-breaking structure cannot completely break up the hardened material on top of the pile, creating cavities (this hardened material will be located vertically above the discharge machine as it moves). If this hardened material collapses, the material accelerated by gravity will crash into the discharge machine. The impact of the high-energy material on the discharge machine may damage it.

Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the protection scope of the present invention.

[0038] Example 1:

[0039] In existing technology, flat warehouses are used to store materials. A trench is located inside the warehouse, with a gate above the trench and a conveyor belt inside. When materials need to be transported out of the warehouse, the gate is opened to allow the materials to enter the trench, and then the conveyor belt outputs the materials. To ensure that all materials in the warehouse enter the trench, a discharge device is required. During operation, the discharge device moves along the bottom of the accumulated materials, transporting them to the trench of the warehouse. This requires the materials to have good flowability. However, some materials may harden after long-term storage. Even after the discharge device removes the hardened material from the bottom, the remaining material may still remain hardened. Existing anti-bridging devices may cause the discharge device to penetrate into the bottom of the accumulated material when breaking the hardened material. If the hardened material collapses, the falling material above the discharge device may damage it. To solve this problem, Embodiment 1 of this invention provides a suspended anti-bridging discharge machine for flat warehouses, such as... Figures 1 to 9 As shown, it includes a boom device 1, a scraper device 2 for breaking up clumped materials, and an auger device 3 for conveying and transferring materials; the top of the boom device 1 is installed on the traveling mechanism on the top of the flat warehouse, and the bottom of the boom device 1 can extend to the bottom of the flat warehouse; the scraper device 2 is fixed on the boom device 1; the auger device 3 is fixedly installed at the bottom of the boom device 1.

[0040] In the flat warehouse suspended arch-breaking and unloading machine provided in Embodiment 1 of the present invention, the boom device 1 needs to be suspended from the traveling mechanism (such as a crane) on the top of the flat warehouse during operation. The unloading auger device 3 is fixed to the boom device 1. When the traveling mechanism on the top of the flat warehouse moves, the unloading auger device 3 will move accordingly. The unloading auger device 3 is initially set at the bottom of the inner side of the flat warehouse and is suspended by the boom device 1. The traveling mechanism on the top of the flat warehouse is fixed to the top of the flat warehouse, and the height of the material piled up inside the flat warehouse is lower than that of the traveling mechanism on the top of the flat warehouse. When the traveling mechanism on the top of the flat warehouse moves, the unloading auger device 3 will move with the traveling mechanism on the top of the flat warehouse, and the scraper device 2 fixed to the boom device 1 will also move with the movement of the traveling mechanism (the scraper device 2 exists in the prior art). The existing scraping device 2, assembled onto the boom device 1, can achieve the arch-breaking operation of caking materials. The scraping device 2 can pre-stir the material in the direction of travel of the auger device 3 (i.e., the caking material above the auger device 3 is broken by the scraping device 2, and the broken material falls to a place that can be pushed by the auger device 3). The material broken by the scraping device 2 will not fall onto the auger device 3 as a whole caking solid, thus avoiding damage to the auger device 3. Compared with the existing technology, the arch-breaking structure is based on the structure extending from the auger device 3. In this embodiment, since the boom device 1 extends from the top of the flat warehouse to the bottom of the flat warehouse, it can completely and more thoroughly break the arches of the material in front of the upper side in the direction of travel of the auger device.

[0041] The arch-breaking structure fixed to the discharge device in the prior art cannot be set too large, because if it is set too large, it will affect the normal movement of the discharge device. If the arch-breaking structure is set too high, the center of gravity of the discharge device and the arch-breaking device as a whole will be very high, which will make the discharge device easy to tip over during movement.

[0042] In this embodiment, since the auger device 3 is suspended from the traveling mechanism on the top of the flat warehouse by the boom device 1, and the driving force is provided by the traveling mechanism on the top of the flat warehouse, there will be no tipping phenomenon. The scraper device 2 fixed on the boom device 1 can fully pre-break the arches of the material on the upper side in front of the auger device 3 in the direction of travel, thus preventing the lumpy material from falling directly onto the auger device 3 in a large solid form. Furthermore, by adjusting the structure of the scraper device 2, the material in front of the auger device 3 in the direction of travel can be broken up by the scraper device 2 first, becoming free-flowing particles before falling down, and then the auger device 3 moves to this position. This further prevents the broken material from hitting the auger device 3, thereby further preventing the auger device 3 from being damaged by the lumpy material.

[0043] The suspended arch-breaking discharge machine for flat warehouses provided by this invention solves the problem in the prior art that the discharge device is easily damaged by collapsing slab materials during operation. The device proposed in Embodiment 1 of this invention can prevent the slab materials from collapsing and damaging the discharge device during operation.

[0044] Since the auger device 3 is suspended from the traveling mechanism on the top of the external flat warehouse by the boom device 1, after the auger device 3 comes into contact with the accumulated material, the auger device 3 and the traveling mechanism on the top of the flat warehouse will jointly apply force to the boom device 1. These two forces are in different directions, and the boom device 1 needs to remain vertical. The two opposing forces may cause the boom device 1 to break. Therefore, to avoid the breakage of the boom device 1, as a preferred solution in this embodiment, the boom device 1 includes an upper connecting assembly 11 for connecting the traveling mechanism, a boom assembly body 12, and a lower connecting assembly 13; the scraper device 2 is fixed on the boom assembly body 12; the upper connecting assembly 11 and the boom assembly body 12 are rotatably connected by a rotatable structure; the lower connecting assembly 13 and the boom assembly body 12 are rotatably connected by a rotatable structure; the auger device 3 is fixedly connected to the lower connecting assembly 12; the rotating shafts of all the rotatable structures are parallel to each other; the rotating shafts of the rotatable structures are perpendicular to the traveling direction of the traveling mechanism. When the traveling mechanism at the top of the flat warehouse applies force to the boom device 1, causing the boom device 1 to move along with the traveling mechanism at the top of the flat warehouse, the scraper device 2 will be subjected to the reaction force of the accumulated material. This reaction force will be adjusted by the rotatable structure 12 between the boom device 1 and the traveling mechanism at the top of the flat warehouse. At this time, the boom device 1 will no longer be in a vertical state. The boom device 1, the auger device 3, and the scraper device 2 will generate a horizontal component of their own weight due to their tilted posture. This force will offset the reaction force from the accumulated material on the auger device, instead of letting the connection between the boom device 1 and the traveling mechanism at the top of the flat warehouse bear the reaction force from the auger device alone. Therefore, the existence of the rotatable structure of the upper connecting component 11 and the lower connecting component 13 can make the boom device 1 more stable. The rotatable connection between the auger device 3 and the lower connecting component 13 can ensure that the side of the auger device 3 used to move the material is always facing the material, preventing the auger device 3 from failing to properly transport the material to the trench after the boom device 1 is tilted.

[0045] Because the bunker is very tall and contains a lot of material, it is impractical to install many arch-breaking structures on the entire boom assembly 1. Furthermore, multiple arch-breaking structures would require the boom assembly 1 to have very high strength to support the entire structure. In this embodiment, the scraping device 2 includes a moving device 21 and a scraping component body 22 that can transform the caking material into a loose state. The moving device 21 is fixed to the boom assembly body 12; the scraping component body 22 is fixed to the moving device 21; the moving device 21 can drive the scraping component body 22 to move. The scraping component body 22 serves as a structural unit for breaking up caking materials. The scraping component body 22 moves via the moving device 21, which is fixed to the boom assembly 1. The scraping component body 22 can move near the boom assembly 1 via the moving device 21. The boom assembly 1 extends from the top to the bottom of the bunker, so the moving device 21 can fully break up the arches around the boom assembly 1 using the scraping component body 22.

[0046] For the aforementioned moving device 21, in order to specifically realize the movement of the scraper assembly body 22 through the moving device 21, as a preferred embodiment, the moving device 21 includes a fixed frame 211, a walking drive assembly 212, a slide rail 213, and a carriage 214; the fixed frame 211 is fixed on the boom assembly body 12; the walking drive assembly 212 is fixed on the fixed frame 211; the slide rail 213 is fixed on the fixed frame 211; the carriage 214 is slidably fixed on the slide rail 213; the walking drive assembly 212 can drive the carriage 214 to slide along the slide rail 213; and the scraper assembly body 22 is fixed on the carriage 214. The scraper assembly body 22 is fixed on the slide 214. When the slide 214 moves on the slide rail 213, the scraper assembly body 22 will move along the extension direction of the slide 214 relative to the slide rail 213 (the travel drive assembly 212 can drive the slide 214 on the slide rail 213 to move along the slide rail 213, which is the prior art, such as using steel cable traction or using cylinder push).

[0047] To specifically realize the movement of the carriage 214 relative to the slide rail 213 by the walking drive assembly 212, in this embodiment, the walking drive assembly 212 includes a walking motor 2121, a walking reducer 2122, a plurality of driven sprockets 2123, a drive chain 2124, and a traction chain fixing bracket assembly 2125; the traction chain fixing bracket assembly 2125 is fixed on the fixing frame 211; the walking motor 2121, the walking reducer 2122, and the driven sprockets 2123 are fixed on the traction chain fixing bracket assembly 2125; the walking reducer 2122 is fixedly engaged with the walking motor 2121; a drive sprocket 2126 is fixed on the output shaft of the walking reducer 2122; the drive sprocket 2126 meshes with the drive chain 2124; the drive sprocket 2126 can drive the drive chain 2124 to move; the drive chain 2124 meshes with the driven sprockets 2123; and the carriage 214 is fixedly connected to the drive chain 2124. The rotation of the travel motor 2121 drives the rotation of the travel reducer 2122, which in turn drives the rotation of the drive sprocket 2126. The drive chain 2124 is meshed with the drive sprocket 2126 and the driven sprocket 2123. The driven sprocket 2123 tensions and steers the drive chain 2124. The rotation of the drive sprocket 2126 causes the drive chain 2124 to move, thereby moving the carriage 214 fixed to the drive chain 2124 (the direction in which the drive chain 2124 pulls the carriage 214 is towards the extension direction of the slide rail). This allows the slide 214 to move on the slide rail 213; (chain drive is the preferred solution in this embodiment. The walking drive component 212 is not necessarily a chain structure, such as a wire rope and drum structure. Driving the slide 214 on the slide rail 213 by pulling the end of the wire rope can also achieve the same driving effect.) With the walking drive component 212, the scraper assembly body 22 itself does not necessarily need to have the function of breaking the arch. Its structure can achieve the function of breaking the arch of the scraper assembly body 22 by moving the scraper assembly body 22 through the moving device 21.

[0048] As a preferred embodiment, in this embodiment, a position sensing component 2131 is provided on the slide rail 213; the position sensing component 2131 can sense the position of the carriage 214 on the slide rail 213. The position sensing component 2131 can monitor the position of the carriage 214 relative to the slide rail 213 (the position sensing component 213 can use a common infrared sensor or ultrasonic sensor in the prior art to detect the position of the carriage 214 on the slide rail 213, which is prior art and will not be described in detail here). The position sensing component 2131 is electrically connected to an external control device, and the external control device is electrically connected to a walking motor 2121. The walking motor 2121 is controlled according to the feedback signal of the position sensing component 2131, thereby more precisely controlling the sliding direction of the carriage 214 relative to the slide rail 213.

[0049] As a preferred embodiment, in this case, the slide rail 213 extends vertically. Since the slide rail 213 extends vertically, the movement direction of the carriage 214 relative to the slide rail 213 is also vertical. Its specific structure is as follows... Figure 8 As shown. Since the sliding carriage 214 moves vertically relative to the sliding rail 213, the scraper assembly body 22 fixed on the sliding carriage 214 is designed to fully break up the arches of the material on one side of the flat warehouse. Its arch-breaking structure extends laterally, and this laterally extended structure may be completely inside the accumulated material. Its advantage is that the entire sliding carriage 214 has such... Figure 8 In the middle, the chain 2124 driven by the walking motor 2121 hangs vertically at both ends, and the slide 214 is fixed at the hanging part of the chain 2124. When one slide 214 moves vertically downward or upward, the slide 214 fixed on the other side of the chain 2124 and the structure fixed on the slide 214 can act as a counterweight to assist the walking motor 2121 in working. The walking motor 2121 only needs to overcome the resistance of the caking material on the scraper assembly body 22, and does not need to overcome the weight of the scraper assembly body 22 itself each time it moves vertically upward. The driving force required by the walking motor 2121 is small. A slide 214 is set on each side because after the equipment moves from one side of the flat warehouse to the other side, the equipment does not need to return through the walking mechanism on the top of the flat warehouse. When the walking mechanism moves the equipment in the opposite direction, the equipment can also use the slide 214 on the other side and the scraper assembly body 22 fixed on this side to break up the material arch.

[0050] However, the above method presents a problem: the scraper assembly body 22 itself has a drive structure, but this drive structure does not have the function of breaking up material bridging. When the drive component of the scraper assembly body 22 encounters caking material, it will have difficulty moving. To avoid this situation, another preferred solution is that, in this embodiment, the slide rail 213 extends horizontally. The slide rail 213 extends horizontally (this horizontal direction is perpendicular to the horizontal direction of the top traveling mechanism), so the movement direction of the carriage 214 relative to the slide rail 213 is horizontal. Its specific structure is as follows... Figure 1 As shown; Figure 1 When the equipment is working, the drive structure of the scraper assembly body 22 is positioned above the accumulated material. The core part of the scraper assembly body 22 used for breaking arches extends vertically, allowing the scraper assembly body 22 to fully scrape one surface when it moves horizontally with the slide 214. Due to the vertically extending structure of the scraper assembly body 22, its drive structure can be located at one end in the vertical direction. Figure 1 The middle part is located at the top vertically, so it can always remain above the top of the material and therefore will not directly contact the caking material.

[0051] To ensure that the scraping device 2 can be stably fixed on the support rod 11, in this embodiment, the discharge auger device 3 includes a main frame assembly 31 and a discharge auger assembly 32; the main frame assembly 31 is fixed on the lower connecting assembly 13; the discharge auger assembly 32 is fixed on the main frame assembly 31; the discharge auger assembly 32 includes a discharge auger 321, an auger support 322, a conveyor reducer 323, and a conveyor motor 324; the conveyor motor 324 and the conveyor reducer 323 are fixed on the main frame assembly 31; the conveyor motor 324 and the conveyor reducer 323 are fixed together; the output shaft of the conveyor reducer 323 is connected to the discharge auger 321; the rotating shaft of the discharge auger 321 is horizontal; the auger support 322 is fixed on the main frame assembly 31; the discharge auger 321 and the auger support 322 are rotatably connected. The conveyor motor 324 rotates, driving the main shaft of the conveyor reducer 323 to rotate. The main shaft of the conveyor reducer 323 is connected to the discharge auger 321, driving the discharge auger 321 to rotate along its main shaft. The discharge auger 321 is an auger that pushes the material in one direction when it rotates. The end point of the push of the discharge auger 321 is at the groove opened in the flat warehouse. The auger support 322 is used to stably fix the auger support 322 on the main frame assembly 31.

[0052] Compared to existing hopper discharge machines, the discharge device in this embodiment is suspended rather than fixed to a ground track. Furthermore, the rotatable structure in this embodiment means the distance between the discharge device and the ground may change. Uneven ground can also cause the discharge auger 3 to collide with the ground. To prevent damage to the discharge auger 3 during its detachment and return to the ground, in this embodiment, the main frame assembly 31 includes a main frame structural member 311, a baffle plate 312, and anti-scratch casters. The main frame structural member 311 is fixed to the lower connecting assembly 13; the baffle plate 312 is fixed to the main frame structural member 311; and the anti-scratch casters are fixed to the main frame structural member 311. The anti-scratch casters prevent the remaining parts of the discharge auger 3 from directly contacting the ground. Baffles are a common structure in outgoing conveyors, used to assist the outgoing auger in conveying (guiding) materials; anti-scratch casters ensure that the outgoing auger device 3 always makes priority contact with the ground when the distance between the outgoing auger device 3 and the ground changes, thereby preventing the rest of the outgoing auger device 3 from colliding with the ground and being damaged.

[0053] In a preferred embodiment, the scraper assembly body 22 includes a scraper bracket 221, a rotating scraper assembly 222 with a rotating shaft, a fixed scraper assembly 223, several scraper support assemblies 224, a rotating scraper reducer 225, and a rotating scraper motor 226. The scraper support assemblies 224, the rotating scraper reducer 225, and the rotating scraper motor 226 are fixed on the scraper bracket 221. The rotating scraper reducer 225 and the rotating scraper motor 226 are fixed together. The rotating shaft of the rotating scraper reducer 225 is coaxial with and fixedly connected to the rotating shaft of the rotating scraper assembly 222. The rotating scraper reducer 225 can drive the rotating scraper assembly 222 to rotate along the rotating shaft. The scraper support assemblies 224 are rotatably connected to the rotating scraper assembly 222. The fixed scraper assembly 223 is fixed on the scraper bracket 221. When the rotary scraper motor 226 is working, it can drive the rotary scraper assembly 222 to rotate. The rotation of the rotary scraper assembly 222 will break the arches of the caking material. The fixed scraper assembly 223 applies pressure to the caking material by the scraper assembly body 22 moving with the slide relative to the slide rail, thereby breaking the arches of the material. The scraper assembly body 22 itself does not have the ability to break the arches. The fixed scraper assembly 223 can be covered on the structure that cannot actively break the arches of the caking material (such as covering the rotary scraper reducer 225 and rotary scraper motor 226, as well as the scraper support assembly 224, which will enter the caking material). This makes these structures unable to break the arches of the caking material after being submerged in the material pile, thus forming greater resistance. For structures that will not be submerged in the caking material pile, the fixed scraper assembly 223 structure does not need to be set outside the structure.

[0054] Compared to existing silo unloading machines, the unloading device in this embodiment is suspended. Since the ground inside the flat silo may not be flat, and the height of the silo cannot be precisely determined initially, the lower connecting component 13 includes a height adjustment component 131 and an elastic buffer component 132. The height adjustment component 131 adjusts the height of the lowest point of the lower connecting component 13 from the ground. The elastic buffer component 132 buffers the upward force from the lowest point of the lower connecting component 13. The unloading auger device 3 is fixed at the lowest point of the lower connecting component 13. The height adjustment component 131 allows for pre-adjustment of the overall height of the equipment, ensuring the bottom of the unloading auger device 3 is flush with the ground. The elastic buffer component 132 provides cushioning for any protrusions or depressions in the flat silo ground, allowing the unloading auger device 3 to automatically adjust its distance from the top of the flat silo within its movement range.
