Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of grain silo unloading equipment, specifically to a shallow circular silo multi-point unloading center guide device. Background Technology
[0002] Shallow round silos are storage facilities used to store granular materials, especially grains. In the process of grain storage and processing, the design and management of the warehouse have an important impact on grain quality and storage efficiency. Traditional grain silo unloading systems generally adopt a single-point unloading method. Although this method is relatively simple, it often encounters a variety of problems in actual operation, the most critical of which is uneven material distribution.
[0003] Because grains vary in size, they accelerate at different rates. Feeding from a single chute can easily cause grain grading, affecting the uniformity of the grain. Furthermore, the high feeding speed from a single chute can cause the grain to break upon impact with the bottom of the grain silo, affecting the yield of high-quality grain. In addition, the scattered grain has an angle of repose and cannot fill the grain silo, resulting in wasted space. Therefore, a device is needed to solve these problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a shallow circular silo multi-point unloading center guide device, which solves the problems of uneven material distribution leading to easy breakage and easy waste of space inside the grain silo.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a shallow circular silo multi-point unloading center guide device, including a discharge pipe, the discharge pipe penetrating the top of the shallow circular silo for inputting grain, the bottom of the discharge pipe being connected to a center guide pipe, and the inner wall of the center guide pipe being provided with a buffer mechanism to reduce grain breakage;
[0006] One side of the feeding pipe is connected to a feeding pipe. There are multiple feeding pipes arranged radially along the axis of the feeding pipe. The outer wall of the feeding pipe is provided with a connecting port. The connecting port is connected to the inside of the feeding pipe to discharge material into the inside of the feeding pipe. The surface of the connecting port is provided with a baffle through a rotating shaft to close the connecting port.
[0007] The feed pipe is equipped with a conversion mechanism to close the bottom central guide pipe, and the inner wall of the central guide pipe is provided with multiple discharge ports to discharge grain.
[0008] Optionally, the buffer mechanism includes a buffer hopper and a collection hopper. The buffer hopper is inverted conical and is disposed on the axis of the central guide pipe. The collection hopper is inverted conical and is disposed on the inner wall of the central guide pipe to collect grain. Both the bottom of the buffer hopper and the bottom of the collection hopper are provided with through holes to allow grain to leak out.
[0009] Optionally, the collecting hopper is located below the buffer hopper, and there are multiple collecting hoppers and buffer hoppers, with each collecting hopper and buffer hopper forming a group.
[0010] Optionally, the conversion mechanism includes a fixed end, a movable end, and a first telescopic rod. The fixed end is fixedly connected to the inside of the feeding tube, and the movable end is sleeved inside the fixed end and can move up and down. The first telescopic rod is fixedly connected to the inner wall of the fixed end, and the telescopic end of the first telescopic rod is fixedly connected to the top of the movable end. The movable end fits against the inside of the feeding tube to seal the feeding tube.
[0011] Optionally, the outer surface of the feed tube is connected to a second telescopic rod via a rotating shaft. The telescopic end of the second telescopic rod is connected to a baffle via a connecting rod. The second telescopic rod is used to control the opening and closing of the baffle.
[0012] Optionally, a clearance groove is provided at the top of the end of the fabric tube near the feed tube to avoid the second telescopic rod.
[0013] Optionally, a dust removal mechanism is provided at the end of the fabric tube away from the discharge tube to reduce dust during the discharge process. The dust removal mechanism includes an air extraction pipe and a flow guide. The flow guide is conical and is provided at one end of the fabric tube. The air extraction pipe is located in the middle of the flow guide and extends through the flow guide to remove dust.
[0014] Optionally, a steel wire rope is provided on one side of the feeding pipe, and the end of the steel wire rope away from the feeding pipe is fixedly connected to the upper surface of the feeding pipe.
[0015] This utility model provides a shallow circular silo multi-point unloading center guide device, which has the following beneficial effects:
[0016] 1. Through the coordinated arrangement of the feeding pipe, distribution pipe, central guide pipe, and conversion mechanism, during the feeding process inside the grain silo, the conversion mechanism can close the central guide pipe, allowing the grain to be transported from the side distribution pipe to the periphery of the grain silo. The repeated opening and closing of the conversion mechanism can continuously change the feeding of the grain silo around the central distribution pipe and distribution pipe, thereby making the distribution of grain more uniform and reducing the occurrence of grading.
[0017] 2. Through the coordinated design of the feeding pipe, central guide pipe, and buffer mechanism, during the central feeding process, the grain falling from the central guide pipe will accumulate in the buffer mechanism. The collision between the grain in the buffer mechanism and the grain above reduces the falling speed of the grain, thereby reducing the possibility of grain damage caused by impact with the grain silo floor and improving the integrity of the grain particles. At the same time, after the central feeding, a layer of grain can be laid at the bottom of the grain silo to provide cushioning when the feeding pipe is feeding, reducing the possibility of grain falling from the feeding pipe and being damaged by impact with the ground.
[0018] 3. Through the coordinated arrangement of feeding pipes, connecting ports, and baffles, multiple feeding pipes can be used to feed grain sequentially. By feeding grain in a circumferential manner, the grain can be distributed more evenly within the grain silo. At the same time, the feeding pipes are located on the outside of the feeding pipes, so that the grain silo can be filled as much as possible when feeding through the feeding pipes, preventing the possibility of wasting space due to the grain not being completely filled on the top wall of the grain silo if only the center is fed.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0027] Please see Figures 1 to 6 This utility model provides a technical solution: a shallow circular silo multi-point unloading center guide device, including a discharge pipe 1, which passes through the top of the shallow circular silo to input grain, and a center guide pipe 2 connected to the bottom of the discharge pipe 1. The inner wall of the center guide pipe 2 is provided with a buffer mechanism to reduce grain breakage.
[0028] A feeding pipe 3 is connected to one side of the feeding pipe 1. There are multiple feeding pipes 3, which are arranged radially along the axis of the feeding pipe 1. The outer wall of the feeding pipe 1 is provided with a connecting port 4. The connecting port 4 is connected to the inside of the feeding pipe 3 to discharge the material into the inside of the feeding pipe 3. The surface of the connecting port 4 is provided with a baffle 5 through a rotating shaft to close the connecting port 4.
[0029] The feed pipe 1 is equipped with a conversion mechanism to close the bottom central guide pipe 2. The inner wall of the central guide pipe 2 is provided with multiple discharge ports 16 for discharging grain.
[0030] Grain enters from the top feed pipe 1, flows along the feed pipe 1 into the bottom central guide pipe 2, and is then transported from the central guide pipe 2 to the ground of the grain silo. The internal buffer mechanism provides cushioning during the grain's fall, reducing the possibility of grain breakage. After the baffle 5 is opened, grain can enter the distribution pipe 3 through the side connection port 4. The distribution pipe 3 can transport the grain to the periphery of the grain silo. The distribution pipe 3 and the central guide pipe 2 alternate feeding, which allows the grain to be continuously fed alternately between the center and the periphery of the grain silo, which helps to improve the uniformity of grain distribution within the grain silo. The switching mechanism can control the opening and closing of the central guide pipe 2, thereby controlling the falling position of the grain. The outside of the central guide pipe 2 is also equipped with a duct for air guidance.
[0031] In this embodiment, as a preferred option, the buffer mechanism includes a buffer hopper 6 and a collecting hopper 7. The buffer hopper 6 is arranged in an inverted cone shape on the axis of the central guide pipe 2, and the collecting hopper 7 is arranged in an inverted cone shape on the inner wall of the central guide pipe 2 to collect grain. Both the bottom of the buffer hopper 6 and the bottom of the collecting hopper 7 are provided with through holes to allow grain to leak out. The collecting hopper 7 is located below the buffer hopper 6. There are multiple collecting hoppers 7 and buffer hoppers 6, and each collecting hopper 7 and buffer hopper 6 are arranged as a group.
[0032] The diameter of the top of the buffer hopper 6 is smaller than the diameter of the central guide pipe 2, and the bottom has an opening with a diameter smaller than the top diameter. During the falling process, some grain will accumulate in the buffer hopper 6, thus forming a buffer section to buffer the grain above. At the same time, due to the opening at the bottom, the grain in the buffer hopper 6 will also gradually fall, and the grain falling from above will fill the buffer hopper 6 again. The diameter of the top of the collecting hopper 7 is the same as the diameter of the central guide pipe 2. The grain passing through the buffer section will be dispersed around the buffer section. The collecting hopper 7 gathers the grain from the surrounding area, causing the grain to fall from the center of the collecting hopper 7 and fall again into the buffer hopper 6 below. The buffer hopper 6 and the collecting hopper 7 are alternately set to buffer the grain in the central guide pipe 2.
[0033] In this embodiment, as a preferred option, the conversion mechanism includes a fixed end 8, a movable end 9, and a first telescopic rod 10. The fixed end 8 is fixedly connected to the inside of the feed tube 1, and the movable end 9 is sleeved inside the fixed end 8 and can move up and down. The first telescopic rod 10 is fixedly connected to the inner wall of the fixed end 8, and the telescopic end of the first telescopic rod 10 is fixedly connected to the top of the movable end 9. The movable end 9 fits against the inside of the feed tube 1 to close the feed tube 1.
[0034] The fixed end 8 is fixedly installed inside the feed pipe 1. The end of the first telescopic rod 10 is connected to the fixed end 8, and the telescopic part is connected to the movable end 9. When the first telescopic rod 10 is retracted, the movable end 9 can be stored inside the fixed end 8, so that there is a gap between the movable end 9 and the inner wall of the feed pipe 1, allowing the grain to fall into the central guide pipe 2 through the gap. After the telescopic part extends, it will push the movable end 9 downward, so that the movable end 9 fits together with the feed pipe 1, preventing the grain from entering the central guide pipe 2. After the grain accumulates in the feed pipe 1, it will be transported to the periphery of the grain bin through the side distribution pipe 3, thereby reducing the occurrence of grain grading due to gravity.
[0035] In this embodiment, as a preferred option, the outer surface of the feeding pipe 1 is connected to a second telescopic rod 11 via a rotating shaft. The telescopic end of the second telescopic rod 11 is connected to the baffle 5 via a connecting rod. The second telescopic rod 11 is used to control the opening and closing of the baffle 5. An avoidance groove 12 is provided on the top of the end of the feeding pipe 3 near the feeding pipe 1 to avoid the second telescopic rod 11.
[0036] The second telescopic rod 11 can drive the connecting rod to move, so that the connecting rod pulls up the baffle 5. When the second telescopic rod 11 extends, the connecting rod can press the baffle 5 onto the connecting port 4 to prevent the grain from overflowing from the connecting port 4 into the feeding pipe 3.
[0037] In this embodiment, as a preferred option, a dust removal mechanism is provided at the end of the material distribution pipe 3 away from the material feeding pipe 1 to reduce dust during the feeding process. The dust removal mechanism includes an air extraction pipe 13 and a flow guide 14. The flow guide 14 is cone-shaped and is provided at one end of the material distribution pipe 3. The air extraction pipe 13 is located in the middle of the flow guide 14 and extends through the flow guide 14 to remove dust.
[0038] During the grain's descent, the guide section 14 can guide the grain to fall in a hollow cylindrical shape. The dust generated during the descent will accumulate in the middle, and the exhaust pipe 13 can extract the gas in the middle position, thereby reducing the dust in the grain silo.
[0039] In this embodiment, as a preferred option, a steel wire rope 15 is provided on one side of the feeding pipe 1, and the end of the steel wire rope 15 away from the feeding pipe 1 is fixedly connected to the upper surface of the feeding pipe 3.
[0040] The wire rope 15 is pulled diagonally on the cloth tube 3 to reduce the downward displacement of the cloth tube 3 due to gravity and improve the overall strength of the device. A winding mechanism can also be set at the top of the wire rope 15. At the same time, a cornering mechanism is set on the cloth tube 3. The tilt angle of the cloth tube 3 can be adjusted by the length of the winding wire rope 15.
[0041] In this invention, the working steps of the device are as follows:
[0042] 1. When in use, connect the feeding pipe 1 to the external input pipe and feed the grain into the feeding pipe 1. At this time, the first telescopic rod 10 is retracted and the movable end 9 is retracted into the fixed end 8. The second telescopic rod 11 is extended so that the baffle 5 closes the connecting port 4. At this time, the grain in the feeding pipe 1 will enter the central guide pipe 2 along the feeding pipe 1. After being buffered by the buffer hopper 6 and the collection hopper 7, it falls onto the ground of the grain bin.
[0043] 2. After laying a layer on the grain warehouse floor, the first telescopic rod 10 extends, so that the movable end 9 extends from the fixed end 8 to close the bottom of the feeding pipe 1. At the same time, the second telescopic rod 11 retracts into one of the feeding pipes 3, so that the baffle 5 opens one of the connecting ports 4, so that the grain in the feeding pipe 1 is transported to one of the feeding pipes 3, and the grain is transported to the periphery of the grain warehouse through the feeding pipe 3.
[0044] 3. After conveying for a period of time, the baffle 5 inside one of the feeding pipes 3 is closed, and the baffle 5 inside another feeding pipe 3 is opened, so that the grain falls from the other feeding pipe 3. This process is repeated until the grain is circulated and discharged from multiple feeding pipes 3 in sequence. After the discharge is completed, the baffle 5 is closed again. At this time, the first telescopic rod 10 retracts and the movable end 9 is retracted into the fixed end 8, so that the grain is conveyed from the discharge pipe 1 to the central guide pipe 2 for central discharge again.
[0045] 4. After the central feeding is completed, the grain is then transported to the feeding pipe 3 for feeding around the perimeter. This process is repeated until the grain silo is full.
[0046] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
