Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material arch breaking, in particular to a flat warehouse suspended arch breaking device. BACKGROUND

[0002] The flat warehouse is a warehouse for stacking materials. The stacking yard of the flat warehouse is rectangular, and the width of the stacking yard is relatively wide, often reaching 30-40 meters, and the depth sometimes reaches more than 200 meters. A plurality of grooves are arranged at the bottom of the flat warehouse, and a gate is arranged at the top of each groove. A conveying belt is arranged in each groove. The gate at the top of each groove is closed in normal times. When it is necessary to output materials, the gate is opened. An unloading conveying device moves the materials at the bottom of the stacked materials into the grooves, and auxiliary materials flow into the grooves. After the materials fall onto the conveying belt, the materials are output by the conveying belt in the grooves.

[0003] When it is necessary to output high-bonding materials such as soybean meal stored in the flat warehouse, the materials are severely bonded after being stacked, and lose fluidity. After the ordinary unloading machine conveys the materials at the bottom in the horizontal direction into the grooves, the unloading conveying device digs a cavity at the bottom of the materials. The other parts of the materials are in a bonded state, which causes the materials above not to fall down. (This part of the bonded materials will be above the unloading machine vertically as the unloading machine moves.) The unloading conveying device cannot convey these materials towards the grooves.

[0004] To solve the above problems, the prior art, such as Chinese Patent Application No. 202310166651.7, discloses a flat warehouse arch breaking unloading machine, an arch breaking unloading system, and an arch breaking unloading method. An arch breaking device is arranged on the unloading machine. The arch breaking device can break the bonded materials in the flat warehouse. The broken materials recover fluidity and fall to the ground. Then the unloading machine moves the broken materials into the grooves.

[0005] However, the arch breaking structure is arranged on the unloading machine that carries the materials. Since the height of the unloading machine is much lower than the height of the materials, the arch breaking structure cannot sufficiently break the materials above that are stacked and bonded in advance. (This part of the bonded materials will be above the unloading machine vertically as the unloading machine moves.) The arch breaking structure can only break the bonded materials around the unloading machine. The materials at positions where the arch breaking structure cannot work may still be in a bonded state. If it is necessary to break the bonded materials in a larger range, the arch breaking structure needs to be arranged very large. In order to sufficiently break the materials above in front of the unloading machine, the arch breaking structure needs to be arranged very high to break the materials stacked high above. However, if the arch breaking structure is arranged in this way, the overall center of gravity of the unloading machine and the arch breaking structure will be very high. Such equipment is difficult to move stably, and is also easy to tip over during operation. SUMMARY

[0031] The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0032] Example 1:

[0033] In existing technology, flat warehouses are used to store materials. These warehouses typically have a trench with a gate above it and a conveyor belt running through the trench. When materials need to be removed from 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 enter the trench, a discharge machine is required. Current discharge machines have a pre-set track on the warehouse floor. The machine moves along the track via a traveling mechanism, and its conveying mechanism transports the materials towards the trench. However, some materials may harden after prolonged accumulation, and the discharge machine, compared to the materials accumulated on the sides, requires a more efficient system. The material is very short, and the discharge machine can only pass through the bottom of the accumulated material. Therefore, existing technologies have incorporated an arch-breaking structure into the discharge machine. However, existing arch-breaking structures can only break up and crush material near the discharge machine. If the existing arch-breaking structure is very long, long enough to fully break up the accumulated material in front of the discharge machine's direction of travel, then the center of gravity of the discharge machine with the arch-breaking structure will be very high. The entire discharge machine, including the arch-breaking structure, is prone to tipping over due to the high center of gravity, which is unstable for the output material. To solve this problem, Embodiment 1 of this invention provides a suspended arch-breaking device for flat warehouses, such as... Figures 1 to 5 As shown, it includes a boom assembly 1 and a scraper 2 for breaking up clumped materials; after the top of the boom assembly 1 is installed on the traveling mechanism on the top of the flat warehouse, the bottom of the boom assembly 1 can extend to the bottom of the flat warehouse; the scraper 2 is fixed on the boom assembly 1.

[0034] The suspended arch-breaking device for flat warehouses provided in Embodiment 1 of this invention requires the use of a traveling mechanism and an outlet machine during operation. The boom device 1 is suspended from the traveling mechanism (such as a crane) at the top of the flat warehouse. The traveling mechanism moves in the same direction as the extension of the trough at the bottom of the flat warehouse. A conventional outlet machine is normally installed above the trough. The traveling mechanism and the outlet machine move synchronously during operation. The traveling mechanism first drives the scraper device 2 to break up the arches in the material. Then, the outlet machine moves to the area where the arches have been broken up and moves the material into the trough. When the traveling mechanism moves, the scraper device 2 fixed on the boom device 1 also moves synchronously. The scraper device 2 moves in the direction of travel of the outlet machine. All the caking material in the warehouse is broken up. Compared with the prior art, the scraping device 2 in this embodiment is attached to the walking mechanism and is not connected to the discharge machine as a whole. Therefore, the center of gravity of the discharge machine will not be too high due to the excessive height of the scraping device 2 (the discharge machine adopts the existing mature discharge machine without the arch-breaking structure). In addition, in this embodiment, the scraping device 2 can start from the top of the material piled up in the flat warehouse and perform sufficient arch-breaking operation on the upper front side of the discharge machine in the direction of travel. This can avoid the situation where there is still caking material that does not fall to the vicinity of the discharge machine after the arch-breaking structure breaks up the caking material near the discharge machine.

[0035] The suspended arch-breaking device for flat warehouses provided by this invention solves the problem in the prior art that the caking material above the warehouse conveying device cannot be fully broken up in advance. The device proposed in the embodiments of this invention enables the arch-breaking device to stably and fully break up the caking material.

[0036] Since the boom device 1 needs to fix the scraper device 2, the boom device 1 is rigid (serving as a structural support for the scraper device 2). When the traveling mechanism moves, the top of the boom device 1 receives a force in the direction of movement of the traveling mechanism, and the bottom of the boom device 1 receives a force in the opposite direction of movement of the traveling mechanism due to contact with the accumulated material. If the boom device 1 needs to remain vertical, the connection between the boom device 1 and the traveling mechanism will be subjected to a large force. If the boom device 1 is directly fixed to the traveling mechanism, the rigid boom device 1 is easily bent. After the boom device 1 is bent, it will affect the normal operation of the equipment. In order to enable the boom device 1 to operate normally after suspending the machine body on the traveling mechanism, as a preferred solution, in this embodiment, the boom device 1 includes an upper connecting component 11 for connecting the traveling mechanism and a boom component body 12; the scraper device 2 is fixed on the boom component body 12; the upper connecting component 11 and the boom component body 12 are rotatably connected by a rotatable structure; the rotating shaft of the rotatable structure is horizontal and perpendicular to the traveling direction of the traveling mechanism. The rotatable structure of the upper connecting component 11 allows the bottom of the boom device 1 (boom assembly body 12 and scraper device 2 fixed on boom assembly body 12) to be subjected to the reaction force of the material. The boom device 1 and the traveling mechanism rotate through the upper connecting component 11, thereby causing the boom device 1 to tilt. The reaction force of the material on the boom device becomes an upward supporting force. The upward component of this supporting force in the vertical direction is offset by the weight of the boom device 1 itself. After part of the weight component of this supporting force is offset, the force against the direction of travel of the traveling mechanism will be reduced. As a result, the force at the connection between the boom device 1 and the traveling mechanism is reduced, and the overall equipment can be more stable and less prone to bending.

[0037] If a large anti-bridging unit, or many anti-bridging units, are installed on the entire boom assembly 12 to effectively break up the caking material near the boom device 1, then due to the large structure of the anti-bridging unit, it will have a significant weight. This necessitates high structural strength for the boom device 1 and the connection between the boom device 1 and the flat-top traveling mechanism, increasing the cost of the boom device 1. Furthermore, if the anti-bridging unit is very large, when the equipment moves with the flat-top traveling mechanism, the contact between the anti-bridging unit and the caking material will cause significant damage. With multiple contact surfaces, the traveling mechanism requires significant force to insert part of the arch-breaking unit into the caking material. If there are many arch-breaking units, and one of them is damaged, the damaged arch-breaking unit 21 will become a resistance to the overall movement of the equipment. To optimize this structure, as a preferred solution, 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 moving mechanism 21 allows the scraper assembly body 22 to move, which reduces the structural weight required by the boom device 1. On the other hand, as a structure that can move actively, the scraper assembly body 22 can break up large areas of caking material with a smaller volume and fewer components. Because the number of scraper assembly bodies 22 is smaller, the probability of failure is also reduced, and the overall maintenance cost of the equipment is lower. The scraper assembly body 22 can break up the caking material near the boom assembly body 12 through the moving mechanism 21, so that the boom assembly body 12 moves synchronously in front of and above the direction of travel of the discharge machine. In this way, the scraper assembly body 22 can fully break up the caking material in front of and above the direction of travel of the discharge machine.

[0038] To specifically realize the function of the mobile device 21 in moving the scraper assembly body 22, as a preferred embodiment, in this embodiment, the mobile device 21 includes a fixed frame 211, a walking drive assembly 212, a slide rail 213, and a slide 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 slide 214 is slidably fixed on the slide rail 213; the walking drive assembly 212 can drive the slide 214 to slide along the slide rail 213; and the scraper assembly body 22 is fixed on the slide 214. The fixing frame 211 can extend the structure of the boom assembly body 12, so that more structures can be fixed on the boom assembly body 12. The walking drive component 212 moves by moving the slide 214 located on the slide rail 213, so that when the slide 214 reciprocates on the slide rail 213, the scraper assembly body 22 fixed on the slide 214 changes position relative to the boom assembly body 12.

[0039] The function of the walking drive assembly 212 is to drive the carriage 214 to move relative to the slide rail 213. Many existing technologies exist for this purpose. As a preferred embodiment, the walking drive assembly 212 includes a walking motor 2121, a walking reducer 2122, several driven sprockets 2123, a drive chain 2124, and a traction chain fixing bracket assembly 2125. The traction chain fixing bracket assembly 2125 is fixed to the fixing frame 211. The walking motor 2121, the walking reducer 2122... 122. The driven sprocket 2123 is fixed on the traction chain fixing bracket assembly 2125; the travel reducer 2122 is fixed in cooperation with the travel motor 2121; the drive sprocket 2126 is fixed on the output shaft of the travel 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 sprocket 2123; the carriage 214 is fixedly connected to the drive chain 2124. When the scraper assembly body 22 needs to be moved, the travel motor 2121 is controlled to work, causing the travel reducer 2122 to work. The drive sprocket 2126 fixed on the travel reducer 2122 rotates. The rotation of the drive sprocket 2126 drives the drive chain 2124 to move. The drive chain 2124 drives the driven sprocket 2123 to rotate. The driven sprocket is used to guide the movement direction of the drive chain 2124 (the movement direction is consistent with the extension direction of the slide rail 213). The carriage 214 is fixed on the drive chain 2124. The movement of the drive chain 2124 drives the carriage 214 to move on the slide rail 213. The walking drive component 212 is not necessarily a chain drive structure; it can also be a steel rope and turntable structure. The steel rope is fixed to the slide 214, and the rotation of the turntable drives the steel rope wound on the turntable to move. The movement of the steel rope pulls the slide 214 to move on the slide rail 213. Furthermore, with the introduction of the walking drive component 212, the scraper component body 22 does not need to have an independent arch-breaking function. The scraper component body 22 can be a scraper, and the movement of the slide 214 relative to the slide rail 213 breaks the arch of the material.

[0040] As a preferred embodiment, in this case, 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 213 can use a common infrared sensor or ultrasonic sensor 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, which is electrically connected to a travel motor 2121. The external control device controls the travel motor 2121 based on the feedback signal from the position sensing component 2131, thereby more precisely controlling the sliding direction of the carriage 214 relative to the slide rail 213.

[0041] The slide rail can extend vertically or horizontally, and the carriage 214 can move along the extension direction of the slide rail 213. These two movements can achieve different technical effects. In this embodiment, the slide rail 213 is arranged to extend vertically. Since the carriage 214 is vertical relative to the moving direction of the slide rail 213, the scraper assembly body 22 fixed on the carriage 214 is designed to fully break up the material on one surface of the flat warehouse. Its structure for breaking up the material is horizontally extended.

[0042] The arch-breaking structure of the scraper assembly body 22 extends laterally, meaning that the entire structure of the scraper assembly body 22 will be completely inside the hardened material during the process of breaking up the hardened material; in order to facilitate the vertical movement of the scraper assembly body 22 along the slide rail 213, the walking drive assembly 213 is provided with two slide rails 213 in this embodiment (e.g., Figure 2 , 5 Two slide rails 213 each have a carriage 214, and the two carriages 214 are connected by a drive chain 2124. The walking drive assembly 213 moves the carriages 214 by moving the drive chain. When one carriage 214 moves vertically upward, the other carriage moves vertically downward. The carriage 214 fixed on the other side of the drive chain 2124 and the structure fixed on the carriage 214 can act as a counterweight to assist the walking motor 2121. The walking motor 2121 only needs to overcome the resistance of the slab material on the scraping assembly body 22, and does not need to... To overcome the weight of the scraper assembly body 22 each time it is moved vertically upward, the driving force required by the walking motor 2121 is small. The combination of a slide rail and a carriage on each side will not result in a waste of resources, 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 carriage 214 on the other side to move relative to the slide rail 213, so that the scraper assembly body 22 fixed on this side can break the arch of the material.

[0043] 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 1When 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 (the driving structure is always higher than the top of the slab material), so it can always remain above the top of the material and therefore will not directly contact the slab material.

[0044] 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.

[0045] In summary, this invention provides a suspended arch-breaking device for flat warehouses, relating to the field of material arch-breaking technology. It includes a suspension rod device and a scraper for breaking up caking materials. The top of the suspension rod device is mounted on a traveling mechanism on the top of the flat warehouse, and the bottom of the suspension rod device extends to the bottom of the flat warehouse. The scraper is fixed to the suspension rod device. This suspended arch-breaking device for flat warehouses solves the problem in the prior art where arch-breaking devices cannot adequately break up caking materials located above the outgoing conveyor. This invention enables the arch-breaking device to stably and adequately break up caking materials.
