Abstract
Description
Technical Field
[0001] This utility model relates to a flat warehouse discharge device, and more particularly to a flat warehouse suspension discharge mechanism, belonging to the field of silo discharge technology for slab materials. Background Technology
[0002] The storage yards of flat warehouses are rectangular, with a width often reaching 30-40 meters, and there is a trend towards wider yards, sometimes exceeding 200 meters in depth. A dedicated unloading machine is required for material discharge. Chinese utility model patent CN 205346364U discloses a track-type unloading machine applied to the bottom of a flat warehouse. This machine can unload materials with good flowability, such as soybeans. However, when flat warehouses store highly compacted materials like soybean meal, the material becomes severely compacted after accumulation, losing its flowability and becoming a solid, concrete-like mass, making it difficult for the aforementioned unloading machine to complete the unloading task.
[0003] Chinese utility model patent CN116002405B discloses a high-layer caking material discharge machine, a flat warehouse discharge system, and a discharge method. It includes a main frame extending laterally and supported by rollers on the ground. A traveling mechanism and a discharge machine discharging material into a central pit are mounted on the main frame. A auger for breaking the caking layer is installed at the top of the main frame. As the main frame moves forward, the auger inserts itself into the caking material at a higher elevation, rotating and reciprocating laterally, creating continuous transverse breaks on the upper material layer's surface to cause it to collapse. The collapsed material is then transported to the central pit by the discharge machine. This technical solution still has the following problems: 1. It requires a 3-4 meter deep pit along the centerline of the flat warehouse floor, with a scraper conveyor installed within; this involves a huge amount of engineering work and investment. Even with a maintenance access, the underground depth of over 200 meters is still very inconvenient; and poor ventilation poses a certain danger. 2. Multiple chains extending along the entire length of the flat warehouse need to be buried in the ground to pull the main frame. Since these chains are buried under the material layer, they are prone to contamination or poor lubrication, and rust is likely to occur over time. Furthermore, malfunctions are difficult to repair. 3. A high degree of flatness is required for the flat warehouse floor.
[0004] With the increasing consumption and storage of soybean meal in my country, there is an urgent need to find reliable solutions for the construction of new warehouses and for breaking up and removing high-density, compacted materials such as soybean meal from warehouses. Utility Model Content
[0005] The purpose of this utility model is to overcome the problems existing in the prior art and provide a suspended warehouse exit mechanism for flat warehouses, which can eliminate the need for a central pit and ground walking and exit mechanisms, thereby reducing the investment in flat warehouses.
[0006] To solve the above technical problems, this utility model provides a suspended discharge mechanism for a flat warehouse, comprising a traveling trolley extending along the width of the flat warehouse. The traveling trolley includes two parallel traveling beams, the two ends of which are connected as one unit by longitudinal short traveling beams. The bottom of the two short traveling beams is provided with traveling rollers. Multiple isosceles triangular frames with their apexes pointing downwards are fixed between the bottom of the two traveling beams. The lower end of each isosceles triangular frame is hinged with a double-headed screw. The lower end of each double-headed screw is hinged to the top center of a breaker frame. The lower end of the breaker frame is suspended by a bottom main beam through multiple bottom hangers. The front and rear sides of the bottom main beam are respectively provided with transverse augers extending along the full width of the flat warehouse. Multiple longitudinal supports are welded to the top of the bottom main beam. The transverse augers are suspended below the ends of each longitudinal support. The outer periphery of the transverse augers is symmetrically wound with positive and negative spiral blades that discharge towards the center.
[0007] Furthermore, the middle part of the transverse auger is connected by an auger intermediate shaft, the middle section of which passes through the output hole of the transverse auger reducer and is connected by a key, and the input end of the transverse auger reducer is driven by the transverse auger motor.
[0008] Furthermore, a lifting mechanism extending between the positive and negative spiral blades of the transverse auger is provided, extending to the space between the two trolley crossbeams.
[0009] Furthermore, the lifting mechanism includes a lifting head sprocket, lifting chains, and a modified downward sprocket. The modified downward sprockets are respectively loosely fitted on the intermediate shaft of the auger via bearings and located on both sides of the transverse auger reducer. A hopper is provided in the middle between the two traveling beams. A head wheel axle parallel to the traveling beam is provided above or on the upper part of the hopper. A pair of lifting head sprockets are fixed on the head wheel axle. The bottoms of the two lifting head sprockets are located in the hopper. The two ends of the head wheel axle extend to the outside of the hopper and are respectively supported on the head wheel bracket via bearing seats. The upper ends of the two lifting chains pass around the lifting head sprockets, and the lower ends of the two lifting chains pass around the modified downward sprockets on the front and rear sides. Multiple bidirectional buckets are evenly provided along the circumference of the two lifting chains.
[0010] Furthermore, one end of the head wheel shaft passes through the output hole of the lifting reducer, the input end of the lifting reducer is driven by the lifting motor, a torque arm is hinged to the lower part of the housing of the lifting reducer, the lower end of the torque arm is hinged to the head wheel bracket, the bottom of the head wheel bracket is supported on the stool frame, and the lower end of the stool frame is fixed to the top center of the arch-breaking swing frame.
[0011] Furthermore, the two ends of the bidirectional bucket are provided with flared openings, and the middle part is provided with a partition plate and has an axisymmetric structure with the partition plate as the boundary. The outer wall of the bidirectional bucket facing the lifting chain is symmetrically provided with bucket support plates. The outer ends of the two bucket support plates are fixedly connected with bucket chain links. The length direction of the bucket chain links is perpendicular to the partition plate and is evenly connected in the chain links of the lifting chain.
[0012] Furthermore, when the bidirectional bucket rises with the lifting chain, the middle partition of the bidirectional bucket is in a horizontal state, the space above the middle partition carries materials, and the space below the middle partition is idle; when the bidirectional bucket reaches the top of the head sprocket, the middle partition is in a vertical state, and the lower edge of the flared mouth becomes a downward slope.
[0013] Furthermore, the bucket support plate is perpendicular to the middle partition and extends into the bidirectional bucket cavity, where it is welded to the middle partition and the inner wall on the other side. Multiple bucket reinforcing rods are also welded between the inner walls of the flared opening.
[0014] Furthermore, one end of the chain pin of the bucket chain link is fixed with a bucket guide wheel, and one side of the lifting chain's upward and downward sections are respectively provided with chain guide rails. Each bucket guide wheel is embedded in the guide groove of the chain guide rail, and the two chain guide rails are fixedly connected to the arch-breaking swing frame.
[0015] Furthermore, the bottom ends of the two head wheel supports are connected as a whole by a transverse frame, and the lower outer wall of the hopper is connected to the transverse frame.
[0016] The head wheel bracket has a head wheel bracket lug welded to its middle outer wall. A tensioning cylinder is hinged to the head wheel bracket lug. The lower end of the tensioning cylinder is hinged to the middle of the upper end of the stool frame.
[0017] The outer walls of the front and rear sides of the head wheel bracket are respectively welded with head wheel bracket guide ears. A head wheel guide rod is fixed in the head wheel bracket guide ears. The lower end of the head wheel guide rod is inserted into the head wheel guide seat. The head wheel guide seat is fixed to the upper corner of the stool frame.
[0018] Compared with the existing technology, this utility model has achieved the following beneficial effects: 1. It eliminates the traditional 3-4 meter deep central pit of the flat warehouse and only requires an exposed central shallow trough. It eliminates the need to install hundreds of discharge gates that need to be opened and closed along the upper end of the central pit, simplifying the moisture-proof measures. It also eliminates facilities such as buried scraper conveyors, sliding contact line power supply devices, and maintenance channels in the pit, saving more than 2 million yuan in civil construction costs for a new flat warehouse.
[0019] 2. Traditional ground equipment, including the ground main frame, wheels and drive mechanism, and discharge scraper, has been eliminated. At least four traction chains more than 200 meters long pre-embedded under the material and the pre-embedded shallow trenches on the ground have also been eliminated, avoiding contamination of the material and corrosion of the equipment itself, reducing the failure rate, and saving approximately RMB 1 million in equipment investment costs.
[0020] 3. The arch-breaking and scraping mechanism moves synchronously with the transverse auger and the central lifting mechanism, reducing the power consumption of ground equipment movement and eliminating speed errors in the supports of each piece of equipment, thus simplifying control requirements.
[0021] 4. The ground-moving unloading machine has high requirements for the flatness of the ground, otherwise the unloading machine cannot move normally, which is especially difficult for flat warehouses with a width of nearly 40 meters; This utility model greatly reduces the requirements for the flatness of the ground in flat warehouses. Even if the ground is not flat, it will not affect the normal discharge. At most, there will be a little more residue on the ground; In particular, it greatly reduces the renovation cost for many old flat warehouses.
[0022] 5. The technical solution of this utility model has all equipment located above ground and outside the material pile, making maintenance and repair very convenient. It will not cause pollution and does not require entering a hidden space for maintenance, thus providing good convenience and safety. Attached Figure Description

[0039] In the following description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device must have a specific orientation.
[0040] For ease of description and understanding, the longitudinal depth of the flat warehouse is referred to as the "front" and "back" directions, and the width direction of the flat warehouse, i.e. the lateral direction of the discharge machine, is referred to as the "left" and "right" directions; the direction facing the material when the equipment is working is simply referred to as the "front" and the direction away from the material is simply referred to as the "back".
[0041] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0043] like Figures 1 to 8 As shown, the suspended warehouse unloading mechanism of this utility model includes an arch-breaking swing frame 1 suspended below the traveling trolley 2, and the traveling trolley 2 and the arch-breaking swing frame 1 extend along the width direction of the flat warehouse.
[0044] Multiple isosceles triangular frames 3 with their vertices pointing downwards are fixed between the bottom of the two overhead crane beams 2a. The top center of the arch-breaking swing frame 1 is hinged to the vertices of the corresponding isosceles triangular frames 3 by multiple double-headed screws 4. The adjustment of the double-headed screws 4 can ensure that the top surface of the arch-breaking swing frame 1 is horizontal, suspending the weight of the arch-breaking swing frame 1 while making the center of gravity of the arch-breaking swing frame 1 fall on the mid-section between the two overhead crane beams 2a; and also enabling the arch-breaking swing frame 1 to support the equipment on it and swing backward at a certain angle.
[0045] The arch-breaking swing frame 1 is matched to the width of the flat warehouse and is suspended by the overhead crane 2, moving forward along the depth direction of the flat warehouse, i.e., towards the material pile. When the arch-breaking mechanism contacts the material pile, the arch-breaking swing frame 1 has the ability to swing at an angle. On the one hand, it has self-adaptive capability, and on the other hand, the tilted arch-breaking swing frame 1 automatically has a counterweight function, so that the arch-breaking mechanism presses against the slope of the material pile for easy scraping. Due to the added weight of the bottom transverse auger and the middle lifting mechanism on the arch-breaking swing frame 1, the arch-breaking swing frame 1 is more stable. Under the appropriate speed of the overhead crane 2, the tilt angle of the arch-breaking swing frame 1 is minimal, or it can remain in a vertical position while moving forward.
[0046] The lower end of the arch-breaking swing frame 1 is suspended by multiple bottom hangers 1a, with a bottom main beam 5 extending along the length of the arch-breaking swing frame 1. Transverse augers 8 extending along the full width of the flat warehouse are respectively installed on the front and rear sides of the bottom main beam 5. Multiple longitudinal supports 5a are welded to the top of the bottom main beam 5, and the transverse augers 8 are suspended below the ends of each longitudinal support 5a by multiple hangers. Positive and negative spiral blades are symmetrically wound around the outer periphery of the transverse augers 8 in the width direction of the flat warehouse. When the transverse augers 8 rotate, the positive and negative spiral blades convey the material in the width direction of the flat warehouse towards the center.
[0047] The middle part of the transverse auger 8 is connected by the auger intermediate shaft, which is a precision-machined optical shaft, and positive and negative spiral blades are arranged on both sides of it.
[0048] The middle section of the auger's intermediate shaft passes through the output hole of the transverse auger reducer 7 and is connected by a key. The input end of the transverse auger reducer 7 is connected to the output end of the transverse auger motor 6. After being reduced in speed by the transverse auger reducer 7, the transverse auger motor 6 drives the rotation of the transverse auger 8. The positive and negative spiral blades on the transverse auger 8 convey the material in the width direction towards the middle.
[0049] The transverse auger reducer 7 has a lifting mechanism with a downward sprocket 22 on each side. The downward sprocket 22 is loosely mounted on the auger intermediate shaft through bearings. The auger intermediate shaft not only serves to center the two downward sprockets 22, but also allows the downward sprockets 22 to rotate relative to the auger intermediate shaft.
[0050] A hopper 15 is provided in the middle between the two overhead crane beams 2a. A head wheel axle 19 parallel to the overhead crane beams 2a is provided on the upper part or above the hopper 15. A pair of lifting head sprockets 20 are fixed on the head wheel axle 19. The bottom of the two lifting head sprockets 20 is located in the hopper 15. The two ends of the head wheel axle 19 extend to the outside of the hopper 15 and are supported on the head wheel bracket 13 by bearing seats. The head wheel bracket 13 supports the top of the stool frame 9. The lower end of the stool frame 9 is fixed to the top center of the arch breaking swing frame 1.
[0051] One end of the head wheel shaft 19 passes through the output hole of the lifting reducer 17. The input end of the lifting reducer 17 is driven by the lifting motor 16. A torque arm 18 is hinged to the lower part of the housing of the lifting reducer 17. The lower end of the torque arm 18 is hinged to the head wheel bracket 13 to counteract the output torque of the lifting reducer 17.
[0052] The upper ends of the two lifting chains 21 pass over the lifting head sprocket 20, the diameter of which is much larger than that of the downward sprocket 22, so that the upper and lower straight sections of the two lifting chains 21 are parallel to each other and extend along the vertical line. The lower ends of the two lifting chains 21 pass over the downward sprockets 22 on the front and rear sides, respectively. Multiple bidirectional buckets 24 are evenly provided along the circumference of the two lifting chains 21.
[0053] A discharge chute is provided along the centerline of the width direction of the flat warehouse. The width and depth of the discharge chute match the rotation trajectory of the bidirectional bucket 24 at the bottom and extend along the entire length of the flat warehouse. The transverse auger 8 conveys the material in the width direction to the discharge chute in the middle, and the bidirectional bucket 24 lifts it to a high position.
[0054] like Figure 7 , Figure 8 As shown, the bidirectional bucket 24 has flared openings 24a at both ends and a central partition 24b in the middle, forming an axisymmetric structure with the partition 24b as the boundary. The outer wall of the bidirectional bucket 24 facing the lifting chain 21 has symmetrically arranged bucket support plates 24c. The outer ends of the two bucket support plates 24c are bent and connected to the bent portions of the bucket chain links 24d by bolts, thus fixing the bucket chain links 24d to the outer ends of the bucket support plates 24c. The length direction of the bucket chain links 24d is perpendicular to the partition 24b and is evenly connected to the links of the lifting chain 21, causing the lifting chain 21 to drive each bidirectional bucket 24 forward.
[0055] When the bidirectional bucket 24 reaches the discharge chute, it is located below the bottom horizontal section of the lifting chain 21, and the flared opening 24a facing the forward direction takes in the material. When the bidirectional bucket 24 passes the lower sprocket 22 and is in the upper section of the lifting chain 21, the flared opening 24a carrying the material faces upward, the middle partition 24b is in a horizontal state, and the lower flared opening 24a is left idle facing downward.
[0056] When the bidirectional hopper 24 reaches the top of the head sprocket, the middle partition 24b is in a vertical state, and the lower edge of the flared mouth 24a forms a 30° inclination angle with the horizontal plane, which facilitates the material to slide out and fall into the collection hopper 15 below.
[0057] The bucket support plate 24c is perpendicular to the middle partition plate 24b and extends into the inner cavity of the bidirectional bucket 24, where it is welded to the middle partition plate 24b and the inner wall on the other side. During manufacturing, a complete bucket support plate 24c can be used, which is welded to the two side wall plates of the flared opening 24a and extends to the outside of the inner corner wall plate and is bent so as to connect with the bent part of the bucket chain link 24d. The bucket support plate 24c has holes in both the inner and outer parts of the flared opening 24a to reduce weight.
[0058] Multiple bucket reinforcing rods 24e are welded between the inner walls of the flared opening 24a. For example, four bucket reinforcing rods 24e are provided along the length of the flared opening 24a to improve the strength of the bidirectional bucket 24 and reduce deformation.
[0059] One end of the chain pin of the bucket chain link 24d is fixed with a bucket guide wheel 24f. Chain guide rails 23 are provided on one side of the upward and downward sections of the lifting chain. The lower part of the chain guide rail 23 is fixed to the arch-breaking swing frame 1, and the upper part of the chain guide rail 23 is fixed to the outer wall of the bench frame 9. When each bidirectional bucket 24 moves upward, the four bucket guide wheels 24f at both ends of its back are respectively embedded in the guide grooves of the chain guide rail 23, ensuring the smooth operation of the lifting chain 21 and the bidirectional buckets 24.
[0060] The bottom ends of the two-wheel support 13 are connected as a whole by the transverse frame 14, and the lower outer wall of the hopper 15 is connected to the transverse frame 14.
[0061] A head wheel bracket ear seat is welded to the outer wall of the middle part of the head wheel bracket 13. A tensioning cylinder 10 is hinged to the head wheel bracket ear seat. The lower end of the tensioning cylinder 10 is hinged to the middle of the upper end of the stool frame 9. Head wheel bracket guide ears are welded to the outer walls of the front and rear sides of the head wheel bracket 13 respectively. A head wheel guide rod 12 is fixed in the head wheel bracket guide ear. The lower end of the head wheel guide rod 12 is inserted into the head wheel guide seat 11. The head wheel guide seat 11 is fixed to the upper corner of the stool frame 9.
[0062] The piston rods of the tensioning cylinders 10 on both sides extend synchronously, lifting the two head wheel supports 13 upwards. The head wheel shaft 19 and the two lifting head sprockets 20 move upwards, keeping the lifting chain 21 under appropriate tension. The head wheel guide rod 12 moves linearly along the head wheel guide seat 11 to ensure the direction during tensioning. During the tensioning and floating process, the collection hopper 15 maintains a constant relative position with the head wheel shaft 19 and the lifting head sprockets 20. The lifting motor 16 and the lifting reducer 17 also rise and fall with the head wheel support 13.
[0063] The stool frame 9 and its tensioning cylinder 10 and head wheel guide seat 11 swing back and forth with the arch-breaking swing frame 1, and the weight of the hopper 15, head wheel shaft 19, lifting head sprocket 20, lifting motor 16, lifting reducer 17, head wheel bracket 13, the tension of the lifting chain 21 and the weight of each bidirectional bucket 24 on it all fall on the arch-breaking swing frame 1.
[0064] A transfer conveyor 25 is provided between the two overhead crane beams 2a, which moves with the overhead crane 2. The inlet of the transfer conveyor 25 receives the material flowing out of the lower port of the hopper 15. The transfer conveyor 25 extends along the length of the overhead crane beam 2a, and its outlet extends outward and upward and connects with the longitudinal conveyor. The longitudinal conveyor is installed on the wall of the flat warehouse.
