Abstract
Description
Technical Field
[0001] This application relates to the field of grain sampling technology, and in particular to an automatic sampling and sorting system. Background Technology
[0002] Currently, warehousing companies store grain using shallow circular silos, large-diameter silos, and vertical silos. Before grain is stored, its quality must be inspected to determine the purchase price and storage conditions based on data on impurities, moisture content, and bulk density. Previously, inspection methods primarily involved sampling the grain transported in vehicles. This method required the vehicle to be parked for sampling, resulting in a lengthy sampling time and making continuous sampling difficult, thus slowing down the inspection process and severely impacting grain receiving efficiency. Utility Model Content
[0003] To address the problem of long sampling times in the past, improve inspection speed, and increase grain collection efficiency, this application provides an automatic sampling and sorting system.
[0004] The automatic sampling and sorting system provided in this application adopts the following technical solution.
[0005] An automatic sampling and sorting system includes a conveyor for transporting grain, a sampler, a divider, and a collector;
[0006] The sampler is located at the end of the conveyor. The sampler includes a moving mechanism and a sampling hopper that is moved along the lateral direction of the conveyor by the moving mechanism. The sampling hopper is connected to a divider through a sampling tube. The divider is used to divide the grain conveyed by the sampling tube. The collector is used to collect the grain after it has been divided by the divider.
[0007] By adopting the above technical solution, and by setting up samplers, dividers, and collectors during the conveyor transport process, i.e. the grain entering the warehouse, automatic sampling and sorting can be achieved during the grain entering the warehouse. The technical solution of this application can automatically sample and sort grain during the grain entering the warehouse, thereby improving the sampling and sorting inspection speed and grain collection efficiency.
[0008] Optionally, the conveyor may include a belt conveyor.
[0009] By adopting the above technical solutions, belt conveyors have advantages such as large conveying capacity, simple structure, convenient maintenance, and standardized components. They can be used to convey loose materials (such as bulk grain) and can achieve rapid, continuous and stable conveying of grain.
[0010] Optionally, the moving mechanism includes a moving bracket, on which a sampling motor, a driving sprocket, a driven sprocket, and a chain mounted on the driving sprocket and the driven sprocket are provided. The driving sprocket is driven to rotate by the sampling motor, and the sampling bucket is connected to the chain.
[0011] By adopting the above technical solution, the sampling bucket is moved by a sprocket and chain, which is simple and reliable.
[0012] Optionally, the sampling hopper is located at the bottom of the movable support and is connected to the chain via a suspension rod.
[0013] Optionally, the boom is provided with a rolling support wheel, which is rotatably mounted on the movable support.
[0014] By adopting the above technical solution, the sampling bucket and the chain are connected by a suspension rod, and the suspension rod is supported on the movable support by a rolling support wheel. The rolling support wheel plays a supporting role, thus realizing the movable setting of the sampling bucket on the movable support and the movement of the sampling bucket under the drive of the chain.
[0015] Optionally, the movable support is provided with a protective cover.
[0016] By adopting the above technical solution and setting up the protective cover, the exposed components, such as the sampling motor, drive sprocket, driven sprocket, and chain, are all covered by the protective cover, which provides protection, waterproofing, dustproofing, and moisture-proofing for all exposed electrical equipment and components, and prevents the rotating parts from rotating inflexibly or getting stuck.
[0017] Optionally, a baffle is provided on the side of the conveyor's conveying end. When the sampling hopper moves to the side of the conveyor's conveying end, the baffle blocks the entrance of the sampling hopper, and the sampling hopper and the baffle are sealed together.
[0018] By adopting the above technical solution, when the sampling hopper moves to the side of the conveyor end, that is, close to the end of the moving support, the baffle blocks the entrance of the sampling hopper. In other words, the entrance of the sampling hopper is blocked by the baffle, and no more grain will enter, so sampling will no longer be carried out.
[0019] Optionally, the moving mechanism is equipped with a limit safety switch and a proximity switch for detecting the sampling hopper.
[0020] Optionally, the collector may include a rotary sample collector.
[0021] Optionally, the automatic sampling and sorting system also includes a return feeder, which includes a return pipe for discharging excess grain from the divider.
[0022] In summary, this application includes at least the following beneficial effects:
[0023] During the grain conveying process via a belt conveyor, i.e., the grain entering the warehouse, the present application utilizes a sampler, a divider, and a collector to achieve automatic sampling and division of the grain during the grain conveying process. Furthermore, the inclusion of a return feeder allows excess grain to be returned to the grain warehouse. The technical solution of this application enables automatic sampling and division of the grain during the grain conveying process, quickly cutting the entire cross-section of the grain laterally. This results in highly representative samples, improves the sampling and division speed, and enhances grain collection efficiency. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] The following is in conjunction with the appendix Figs. 1 to 4 This application will be described in further detail.
[0032] This application discloses an automatic sampling and sorting system.
[0033] Reference Figs. 1 to 4 An automatic sampling and sorting system includes a conveyor 1 for transporting grain, a sampler, a divider 16, and a collector 17.
[0034] The conveyor 1 includes a belt conveyor. The end of the conveyor 1 is located above the grain silo 2. The conveyor 1 enables the transport of grain, i.e., the grain entering the silo. The belt conveyor has the advantages of large conveying capacity, simple structure, convenient maintenance and standardized parts. It is used to transport loose materials (such as bulk grain) and can realize the rapid, continuous and stable transport of grain. When the bulk grain is transported to the end by the belt conveyor, it falls automatically and has a certain initial velocity, falling in a parabolic trajectory.
[0035] The sampler is located at the end of the conveyor 1. The sampler includes a moving mechanism and a sampling hopper 3, which is moved laterally along the conveyor 1 by the moving mechanism. The moving mechanism includes a moving support 4, which is arranged laterally along the conveyor 1 and located above the end of the conveyor 1. A drive sprocket 5 and a driven sprocket 6 are respectively installed at both ends of the moving support 4. Chains 7 are mounted on the drive sprocket 5 and driven sprocket 6 for transmission. A sampling motor 8, which drives the drive sprocket 5 to rotate, is mounted on the moving support 4. The sampling motor 8 is a dust explosion-proof motor. The sampling hopper 3 is located at the bottom of the moving support 4. The top of the sampling hopper 3 is connected to the chain 7 via two suspension rods 9. Rolling support wheels 10 are provided on both sides of the suspension rods 9, and the rolling support wheels 10 are rolled on the moving support 4. The sampling hopper 3 is connected to the chain 7 via the suspension rods 9, and the suspension rods 9 are supported on the moving support 4 by the rolling support wheels 10. The rolling support wheels 10 provide support, thus enabling the sampling hopper 3 to be moved and positioned on the moving support 4. The sprocket and chain 7, when rotated by the sampling motor 8, drive the sprocket to rotate, which in turn moves the suspension rod 9, allowing the sampling bucket 3 to move laterally along the conveyor 1. The lateral movement of the sampling bucket 3 is a full-section cutting type, quickly cutting the entire cross-section of grain laterally, resulting in highly representative samples. When not in use, the sampling bucket 3 rests at both ends of the moving support 4, outside the grain flow, minimizing the impact of the cutting speed on the grain flow. The sampling bucket 3 is made of stainless steel.
[0036] The movable support 4 is equipped with a protective cover 11, which uses a quick-connect method for easy installation and disassembly. The protective cover 11 covers exposed components such as the sampling motor 8, drive sprocket 5, driven sprocket 6, and chain 7, providing protection against water, dust, and moisture for all exposed electrical equipment and components, preventing stiff rotation and jamming of rotating parts.
[0037] Baffles 12 are provided on both sides of the conveying end of the conveyor 1. When the sampling hopper 3 moves to the position on both sides of the conveying end of the conveyor 1, that is, close to the two ends of the moving support 4, the baffles 12 block the entrance of the sampling hopper 3. The entrance of the sampling hopper 3, that is, the side facing the baffle 12, is provided with a sealing structure, such as a sealing ring 13, which is sealed with the baffle 12. That is, the entrance of the sampling hopper 3 is blocked by the baffle 12, and no more grain will enter, and no more sampling will be performed.
[0038] The sampling hopper 3 is inclined on one side near the conveyor 1, and the bottom of the sampling hopper 3 is tapered. By inclining one side, the longitudinal section of the sampling hopper 3 is tapered, that is, the bottom of the sampling hopper 3 is tapered, which facilitates the collection and sampling of grain by the sampling hopper 3.
[0039] The movable support 4 is equipped with limit safety switches 14 and proximity switches near both ends for detecting the sampling hopper 3. The limit safety switches 14 can stop the movement of the sampling hopper 3, ensuring that the sampling hopper 3 stops safely at the designated position. The proximity switches also have a zero-speed detection function, which facilitates speed detection.
[0040] The sampling hopper 3 is connected to the divider 16 via the sampling tube 15. The divider 16 can be a rotary divider. The divider 16 is used to divide the grain delivered by the sampling tube 15. The divider 16 and the pipe are sealed and dustproof, can be cleaned by itself, and can be disassembled at any time for easy inspection and cleaning. The divider 16 can adjust the division ratio as needed to meet the sampling volume requirements according to different flow rates.
[0041] Collector 17 is connected to divider 16 via collection tube 18 and is used to collect the grain after it has been divided by divider 16. Collector 17 can be a rotary sample collector. Collector 17 has twelve digits and collects samples for laboratory analysis to determine grain quality. Collector 17 is dustproof and moisture-proof, and can automatically switch between multiple containers to collect the final grain sample. Collector 17 is fully sealed to prevent dust and moisture loss. Collector 17 includes sample collection bottles and a sealed, dustproof cabinet for holding the sample collection bottles, with a suitable door of sufficient area for removing the sample collection bottles. The sample collection bottles are placed on a motor-driven, rotating disc, and the speed of collecting experimental samples is adjustable. The disc conveyor moves the sample collection bottles, delivering the sample into the bottles without spillage or grain dust generation, and the seal is reliable.
[0042] The automatic sampling and sorting system also includes a return feeder 19, which includes a return pipe. One end of the return pipe is connected to a divider 16, which is used to discharge excess grain that has been divided by the divider 16 into the silo. By setting up the discharge pipe, excess grain during sampling is sent to the silo 2.
[0043] Through the technical solution of this application, during the process of grain being transported by the belt conveyor, i.e. during the grain entering the warehouse, the automatic sampling and sorting of grain is achieved by setting up a sampler, a divider 16, and a collector 17. Furthermore, through the setting up a return feeder 19, excess grain can be sent to the grain silo 2. The technical solution of this application can automatically sample and sort grain during the process of grain entering the warehouse, quickly cut the grain from the entire cross section laterally, resulting in strong sample representativeness, improving the sampling and sorting speed, and improving grain collection efficiency.
