Description

Technical Field

[0001] This utility model relates to the conveying and storage of materials, and more particularly to a flat-bed feeding device. Background Technology

[0002] Existing feeding equipment for storing materials (e.g., grains) in warehouses typically uses a conveyor to transport materials from the outside to the warehouse, and then opens a discharge port at the bottom to allow the materials to fall, thus stacking and storing them in the warehouse. This mechanical method replaces the previous manual method of transporting materials to the warehouse.

[0003] However, existing feeding equipment only has a single fixed discharge port. When the material falls from the discharge port, it will accumulate at a fixed point, that is, the material is concentrated below the discharge port, forming a cone shape. In order to avoid wasting space and reduce the possibility of silo overflow, personnel need to enter the warehouse to push the accumulated material flat, that is, silo leveling operation. This is not only time-consuming and labor-intensive, but also poses the risk of personnel being buried alive by the material or encountering dust explosion. Summary of the Invention

[0004] To address the problem that existing feeding equipment requires additional personnel to level the materials, which is time-consuming, labor-intensive, and carries the risk of burying materials alive, the purpose of this invention is to propose a leveling feeding device that can evenly disperse materials during input, thereby avoiding fixed-point accumulation and eliminating the need for additional manpower for leveling operations.

[0005] The present invention provides a leveling and feeding device for a warehouse, comprising: at least one conveying device for conveying material along a feeding direction and having a plurality of spaced-apart distributing ports; and a plurality of distributing devices, each distributing device corresponding to one of the distributing ports, and each distributing device corresponding to at least one sprinkling port for conveying material from the corresponding distributing port along an extending direction. Each distributing device can convey material from the corresponding distributing port along an extending direction to at least one sprinkling port, allowing the material to leave the leveling and feeding device from the sprinkling port. The feeding direction intersects the extending direction, allowing the sprinkling ports of the plurality of distributing devices to be located at different positions within the warehouse.

[0006] The several material distribution devices are located on both sides of the conveying device.

[0007] Each of the material distribution devices includes a conveying channel and a feeding mechanism. The conveying channel is located between the material distribution port and the spraying port along the extending direction, and the feeding mechanism is used to convey the material in the conveying channel to the spraying port.

[0008] The feeding mechanism is a screw feeder.

[0009] The material distribution device includes a spraying mechanism, with at least one spraying nozzle located on the spraying mechanism. The spraying mechanism can rotate to drive the spraying nozzle to move, causing the material to leave the leveling and feeding equipment in different directions. The spraying mechanism is provided with a rotating shaft and several spraying nozzles, which are arranged at equal angles around the rotating shaft.

[0010] The conveying device includes several gates, each gate being used to close a corresponding material dispensing port. Each gate is electrically connected to a controller and can control the opening and closing of each gate.

[0011] The conveying device includes a chain conveyor.

[0012] The flatbed feeding equipment also includes several conveying devices arranged in parallel, and several material distribution devices distributed below these conveying devices.

[0013] Compared to existing feeding equipment that discharges material at a single fixed point and requires personnel to enter the warehouse for leveling operations, the advantage of this leveling feeding equipment is that it uses a series of distributing devices distributed through a corresponding conveying device. These distributing devices deliver the material along an extension direction intersecting with the feeding direction of the conveying device to the sprinkling port for spraying, filling different areas of the warehouse. As a result, the material can be piled up more evenly in the warehouse, thus eliminating the need for leveling operations. This not only saves manpower and time costs associated with leveling operations but also avoids the risks of personnel being buried alive by materials or dust explosions. Therefore, this invention provides a leveling feeding equipment that improves cost-effectiveness and safety. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model are further described below with reference to the accompanying drawings:

[0025] like Figure 1 and Figure 2 As shown, a preferred embodiment of the flattening and feeding device of this utility model is: installed in a warehouse, used to convey and fill materials into the warehouse. In this preferred embodiment, the conveying and filling of grain G into the grain silo 90 is used as an example. The flattening and feeding device includes two conveying devices 10 and several distributing devices 20, which are distributed below the two conveying devices 10.

[0026] like Figure 1 and Figure 2 As shown, the two conveying devices 10 are arranged at intervals. Each conveying device 10 extends from the outside of the grain silo 90, passes through the interior of the grain silo 90, and extends out from the other side of the grain silo 90. One end of each conveying device 10 is located outside the grain silo 90, allowing personnel to place grain G into the conveying device 10. Specifically, a hopper can be provided to input grain G into the conveying device 10. The conveying device 10 is used to convey material, i.e., grain G, along a feeding direction. The two conveying devices 10 are respectively provided with several spaced-apart distributing ports 11 and several distributing devices 20, with the distributing devices 20 respectively corresponding to the distributing ports 11. Figure 2 , Figure 3 , Figure 4 As shown, the grain G conveyed by the conveying device 10 can be distributed to several of the distributing devices 20 through the several distributing ports 11.

[0027] The plurality of distributing devices 20 are respectively configured corresponding to the plurality of distributing ports 11 of the two conveying devices 10, specifically configured at the bottom, to receive the grain G falling from the plurality of distributing ports 11 respectively; wherein, each of the conveying devices 10 conveys the grain G along a feeding direction D1; the plurality of distributing devices 20 are respectively configured with at least one sprinkling port 41 for conveying the grain G from the corresponding distributing port 11 along an extension direction. In this embodiment, each of the distributing devices 20 can convey the grain G from the corresponding distributing port 11 along an extension direction D2 to at least one sprinkling port 41 of the distributing device 20, so that the grain G leaves the leveling and feeding equipment from the sprinkling port 41 and enters the grain silo 90; the extension direction D2 of the plurality of distributing devices 20 intersects with the feeding direction D1 and is different from each other, so that the sprinkling ports 41 of the plurality of distributing devices 20 are located at different positions within the grain silo 90.

[0028] In the preferred embodiment of this utility model, such as Figure 5 and Figure 6 As shown, each of the material distribution devices 20 includes a sprinkling mechanism 40, which has two sprinkling ports 41. Each of the material distribution devices 20 also has a driving mechanism 30. The sprinkling mechanism 40 is connected to the driving mechanism 30 and can be driven by the driving mechanism 30 to rotate, so as to throw the grain G out from the two sprinkling ports 41.

[0029] The specific structure of each material distribution device 20 conveying along the extension direction D2 is a conveying channel 50 and a feeding mechanism 60, such as... Figure 5 and Figure 6 As shown, the conveying channel 50 is disposed along the extension direction D2 between the corresponding material distribution port 11 (not shown) and the spraying port 41 of the spraying mechanism 40. The feeding mechanism 60 is disposed in the conveying channel 50 and connected to the driving mechanism 30. It can be driven to convey the material from one end of the conveying channel 50 corresponding to the material distribution port 11 to the other end of the conveying channel 50 corresponding to the spraying mechanism 40, and spray the grain G through the spraying port 41.

[0030] In actual filling, it can be as follows: Figure 8 , Figure 9 , Figure 10 As shown, after the grain G is conveyed into the grain silo 90 by the conveying device 10, it can be distributed to the distributing devices 20 through the distributing ports 11. The distributing devices 20 sequentially fill different areas of the grain silo 90 with the grain G. Specifically, the grain G can be filled first by distributing it close to the distributing devices 20. See [link to relevant documentation]. Figure 8 On the right side, when the grain level on the right side of the grain silo is high (G), see [reference needed]. Figure 9 and Figure 10 As shown, then through the location Figure 9 In the center, and nearFigure 10 The feeding devices 20 on the left side fill the grains G until all the grains G are filled into the grain silo 90, or when the grain silo 90 is nearly full, the filling operation is completed.

[0031] Compared to existing feeding equipment that discharges material at a single fixed point and requires personnel to enter the warehouse for leveling operations, this utility model distributes several material distribution devices 20 below the conveying device 10. These devices distribute the material along different extension directions D2 that intersect with the feeding direction D1 of the conveying device 10 and are delivered to the sprinkling port 41 for sprinkling. This allows the material to fill different areas of the warehouse, thereby accumulating the material more evenly within the warehouse. This eliminates the need for leveling operations, saving manpower and time costs associated with leveling operations and avoiding the risks of personnel being buried alive by materials or experiencing dust explosions. This provides a leveling and feeding equipment that improves cost-effectiveness and safety.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, several distributing devices 20 are located on both sides of the corresponding conveying device 10, which can expand the coverage area and ensure that the leveling feeding equipment fills the grain G into different areas of the grain silo 90, thereby maximizing the use of the space inside the grain silo 90. The extending direction D2 of the several distributing devices 20 is as follows: Figure 1 and Figure 2 As shown, they are parallel to each other, or as... Figure 11 The other embodiment shown is bifurcated, and both can achieve the effect of filling grain G into different areas, and are not limited to a specific relationship.

[0033] Furthermore, in a preferred embodiment of this utility model, the sprinkling mechanism 40 is provided with a rotating shaft 42 and several sprinkling nozzles 41, which are arranged at equal angles around the rotating shaft 42. By using the sprinkling mechanism 40, which can be driven to rotate by the driving mechanism 30, the sprinkling nozzles 41 are directed in different directions to sprinkle the grain G outwards, improving the effect of evenly accumulating the grain G within the grain silo 90. In addition, the rotational speed of the sprinkling mechanism 40 can be adjusted by the driving mechanism 30 to control the distance the grain G is sprinkled outwards, thus distributing the accumulated grain G more evenly.

[0034] Furthermore, the sprinkling mechanism 40 is provided with two sprinkling ports 41, and the two sprinkling ports 41 are arranged at equal angles with the rotating shaft 42 as the center. In this way, when the grain G is sprinkled outward, it can be evenly sprinkled in different directions through the two sprinkling ports 41, so that the sprinkled grain G is more evenly piled in the grain silo 90. In other embodiments, the number of sprinkling ports can be one or more. The three or more sprinkling ports can also be arranged at equal angles with the rotating shaft 42 as the center, and all of them can sprinkle the grain G. The number of sprinkling ports is not limited to the preferred embodiment of this utility model.

[0035] Specifically, in this embodiment, the sprinkling mechanism 40 includes two sprinkling troughs 43 connected to the rotating shaft 42, and two sprinkling ports 41 respectively formed at the ends of the two sprinkling troughs 43 away from the rotating shaft 42. When the grain G is conveyed to the outlet of the conveying channel 50 through the feeding mechanism 60, it can enter the sprinkling trough 43 through the opening at the top of the sprinkling trough 43 and be sprayed outward through the sprinkling ports 41 on the outer periphery.

[0036] In other embodiments, the sprinkling mechanism 40 may also adopt other structures, such as using a pipeline structure to transport grain G, or setting one or more sprinkling ports. As long as the sprinkling mechanism 40 has at least one sprinkling port that can sprinkle grain G outward in different directions, the aforementioned effect of more evenly accumulating grain G can be achieved. The specific structure of the sprinkling mechanism 40 is not limited to the above.

[0037] In addition, such as Figure 5 and Figure 6 As shown, the drive mechanism 30 specifically includes a motor 31 and a reducer 32. The reducer 32 is connected to the motor 31, and the rotating shaft 42 of the sprinkling mechanism 40 is connected to the reducer 32. The feeding mechanism 60 adopts a screw feeder. The motor 31 and the feeding mechanism 60 are arranged in a nearly horizontal direction, while the rotating shaft 42 is arranged in a nearly vertical direction. The direction of the output of the motor 31 is adjusted by the reducer 32 so that the rotating shaft 42 can be driven by the drive mechanism 30. In other embodiments, the sprinkling mechanism 40 and the feeding mechanism 60 can also be driven by two motors or other drivers respectively according to the setting requirements, and are not limited to the preferred embodiment of this utility model.

[0038] Preferably, each of the conveying devices 10 includes a plurality of gates 14, such as Figure 3 and Figure 4As shown, each gate 14 is used to open or close one of the corresponding dispensing ports 11. This allows personnel to visually inspect the filling status of each area within the grain silo 90, or to install one or more sensors 80, and to control each gate 14 accordingly. This enables the dispensing device 20 to distribute grain G to areas with available space, and stops dispensing grain G to areas with higher accumulation.

[0039] like Figure 7 As shown, the leveling and feeding device also includes a controller 70, which is electrically connected to the plurality of gates 14 to control the opening and closing of each gate 14. The controller 70 is also electrically connected to the aforementioned sensor 80; the electrical connection can be wired or wireless. The controller 70 can act as a central controller, controlling the opening and closing of each gate 14 to determine whether the grain G is distributed to the corresponding dispensing device 20 through each dispensing port 11. In other embodiments, several controllers can also control several gates separately.

[0040] In addition, in other embodiments, the size of the several distributing ports 11 can also be designed. For example, when conveying a large amount of grain G, by designing the distributing port 11 near the front end of the conveying device 10 to be smaller, the grain G can be controlled to continue to be conveyed towards the rear end, which can also achieve the effect of distributing materials. It is not limited to the design of the several gates 14.

[0041] like Figure 3 and Figure 4 As shown, the gate 14 specifically includes a pressure cylinder 141 and a door plate 142. The door plate 142 is connected to the pressure cylinder 141 and has a door plate opening 143. The pressure cylinder 141 is electrically connected to the controller 70. By controlling the pressure cylinder 141 to drive the door plate 142 to move back and forth, the door plate opening 143 on the door plate 142 is aligned vertically with the corresponding material dispensing port 11, thereby opening the material dispensing port 11.

[0042] In a preferred embodiment of the present invention, each conveying device 10 includes a conveyor 12 and a plurality of hoppers 13. The plurality of hoppers 13 are spaced apart below the conveyor 12. Each gate 14 is located between the conveyor 12 and one of the corresponding hoppers 13. The plurality of distributing ports 11 are formed at the bottom of the plurality of hoppers 13. The arrangement of the hoppers 13 ensures that the grain G falls into the distributing device 20 in a concentrated manner and is less likely to spill out.

[0043] The conveyor 12 can be an existing chain conveyor, such as... Figure 3 and Figure 4As shown, the conveyor 12 includes a track 15, a conveyor chain 16, and several scrapers 17. The track 15 is used to hold grain G, and the bottom of the track 15 is provided with several track openings 151, which correspond to several dispensing ports 11. The conveyor chain 16 is arranged along the track 15 and can be driven by a motor and sprocket to circulate along the track 15. The several scrapers 17 are arranged at intervals on the conveyor chain 16 and can be driven by the conveyor chain 16 to move along the bottom of the track 15, thereby pushing the grain G to achieve the conveying effect.

[0044] Furthermore, such as Figure 1 and Figures 8 to 10 As shown, in a preferred embodiment of the present invention, each conveying device 10 has a first end and a second end that are positioned opposite each other in the feeding direction D1. The first end may be provided with the aforementioned feed hopper for feeding grain G, and the second end may be provided with an overflow discharge mechanism 18 that connects to the outside of the conveying device 10. The overflow discharge mechanism 18 may specifically be provided with a hopper, a discharge pipe, or an opening, as long as it can connect the inside and outside of the conveying device 10.

[0045] If the conveying device 10 or the distributing device 20 malfunctions, for example, if the conveying device 10 or the distributing device 20 fails to stop properly after the silo is full, or if the conveying device 10 fails to properly distribute the grain G to the distributing device 20 during filling, the conveying device 10 can directly discharge the grain G from the second end through the overflow discharge mechanism 18 to avoid silo bursting or damage to related mechanisms due to being filled with grain G.

[0046] In addition, in a preferred embodiment of the present invention, two parallel conveying devices 10 are included, and several material distribution devices 20 are distributed below the two conveying devices 10; in other embodiments, the number and length of the conveying devices 10 and the number of the material distribution devices 20 can be determined according to the length, width and other dimensions of the silo 90, and are not limited to a specific number and size.

[0047] The above-described preferred embodiment of the present invention is illustrated by taking grain G being filled into the grain silo 90 as an example. However, in practical applications, the material filled into the warehouse by the leveling and feeding device of the present invention can also be other powdery or granular materials, all of which can achieve the effect of automatic leveling and eliminating the need for personnel to perform leveling operations. The application form is not limited to the preferred embodiment of the present invention.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical solution provided by the present utility model shall still fall within the scope of the technical solution of the present utility model.
