Description

Technical Field

[0001] This utility model relates to the field of grain storage technology, specifically to a grain storage container equipped with a sampling device. Background Technology

[0002] Grain reserves are of great significance for ensuring food security, responding to risks, and protecting people's livelihoods. Currently, containerized grain storage is widely used for its convenience in loading, unloading, and transportation. However, containerized grain storage requires improvements in grain quality, prevention of mold and pests, and enhanced intelligent management. To address these issues, it is necessary to sample and test the grain stored in the containers, and to monitor for mold and spoilage in a timely manner to ensure grain safety and improve its quality.

[0003] In existing technologies, sampling and testing grain inside grain storage containers presents the following technical problems:

[0004] First, current sampling techniques are inconvenient. Grain storage containers are large and difficult to access. Furthermore, if sampling tools are carried manually and samples are taken by hand, it is not only labor-intensive and cumbersome, but also inefficient and prone to accidents such as dropping sampling equipment.

[0005] Second, the existing technology has a low level of automation. There is a need to develop a sampling device that can be integrated into grain storage containers, which not only eliminates the need for handling and additional storage, allowing for transport with the container and immediate use; but also enables automatic sampling and can collect multiple samples at once, facilitating subsequent analysis of multiple samples. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a grain storage container equipped with a sampling device that has a simple and compact structure, high integration, high degree of automation, convenient sampling and the ability to take multiple samples at one time.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A grain storage container equipped with a sampling device has a sampling port on its top and a sealing cover at the sampling port. The sampling device is installed on the inner side of the sealing cover. The sampling device includes a sampling tube, a driving mechanism, and multiple sample storage compartments arranged along the height of the sampling tube. The multiple sample storage compartments are all connected to the hollow sampling tube. The driving mechanism can drive the sampling tube to move up and down. The bottom of the sampling tube is provided with a grain guiding part. During operation, the driving mechanism drives the sampling tube to be vertically downward and repeatedly inserted into the grain pile so that the grain enters the sampling tube through the grain guiding part and finally enters the multiple sample storage compartments to complete the sampling.

[0009] As a further improvement to the above technical solution:

[0010] The drive mechanism includes a swing arm, a mounting rod, and a motor assembly. The motor assembly is connected to the mounting rod and a sealing cover. One end of the swing arm is connected to the drive end of the motor assembly, and the other end is hinged to the top of the sampling tube.

[0011] An extension rod assembly is fixed on the inner side of the sealing cover. The extension rod assembly is detachably connected to the drive mechanism for removing the sampling device after sampling. The extension rod assembly includes a vertical rod perpendicular to the sealing cover and a horizontal rod perpendicularly connected to the bottom of the vertical rod. The end of the horizontal rod is provided with a threaded portion, and the end of the mounting rod is provided with a fixing hole for the threaded portion to pass through and be fixed by a nut.

[0012] The grain guiding part includes an inclined shovel with a side opening. A movable base plate that can be flipped up and down is hinged to the bottom of the opening of the inclined shovel. A vertical screw is provided on the movable base plate for adjusting the tilt angle of the movable base plate by rotating the screw.

[0013] The inclined shovel has multiple transverse support ribs at its side opening, and these support ribs are arranged at intervals.

[0014] Each sampling tube is equipped with a fence assembly at the opening connecting it to each of the sample storage bins to slow down the speed at which grain enters the sample storage bins.

[0015] The sampling tube has multiple observation holes with a diameter smaller than that of the grains, for observing the condition of the grains inside the sampling tube.

[0016] Each of the sample storage compartments is provided with a sampling port on its side wall, and the sampling port is provided with a movable locking cover for opening and pouring out the grain samples collected in the sample storage compartment.

[0017] The sealing cover is provided with a locking assembly for sealing and locking the sealing cover. A detachable battery assembly is also provided on the inner side of the sealing cover, and a switch assembly is also provided on the outer side of the sealing cover. The sampling device is electrically connected to the switch assembly and the battery assembly respectively.

[0018] The sealing cover is also provided with a sealing ring on the contact surface with the grain storage container.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] First, the grain storage container of this utility model has a high degree of integration. It not only has a sampling port and a sealing cover, but also integrates a sampling device. When not sampling, the sampling device is sealed inside the grain storage container. When sampling is required, the sealing cover needs to be opened to carry out the sampling operation, which completely avoids the drawbacks of existing technologies that require manual carrying of sampling tools, as well as the inability to store and transport sampling tools.

[0021] Secondly, the grain storage container of this utility model has a high degree of automation. During sampling operations, the sealed cover needs to be opened, and the sampling device can automatically take samples instead of manually reaching into the container. This makes the sampling operation convenient, quick, and efficient, greatly reducing the workload and avoiding the risk of accidents.

[0022] Third, the grain storage container of this utility model has multiple sample storage compartments set along the height direction of the sampling tube, and multiple samples can be collected by repeatedly inserting it vertically downwards. It can collect a large amount of samples at one time and a large number of samples, and can achieve grain sampling at different heights and positions, which facilitates subsequent analysis of multiple samples and greatly improves the effectiveness and scientific nature of grain testing and monitoring.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] like Figures 1 to 5 As shown, this embodiment features a grain storage container equipped with a sampling device. The top of the container has a sampling port with a sealing cover 1. A sampling device 2 is installed on the inner side of the sealing cover 1. The sampling device 2 includes a sampling tube 21, a driving mechanism 22, and multiple sample storage chambers 23 arranged along the height of the sampling tube 21. All sample storage chambers 23 are connected to the hollow sampling tube 21. The driving mechanism 22 drives the sampling tube 21 to move up and down. A grain guiding section 211 is provided at the bottom of the sampling tube 21. During operation, the driving mechanism 22 drives the sampling tube 21 vertically downwards, repeatedly inserting it into the grain pile to allow the grain to enter the sampling tube 21 through the grain guiding section 211 and ultimately into the multiple sample storage chambers 23 to complete the sampling. The specific implementation principle is as follows:

[0034] In this embodiment, only a portion of the grain storage container is shown. The grain storage container is as follows: Figure 1As shown in Figure A, a sampling port is provided on the top of the grain storage container, and a sealing cover 1 is provided at the sampling port. Normally, when not sampling is being performed, the sealing cover 1 seals the sampling port for easy grain storage. When sampling is required, the sealing cover 1 is opened, and the sampling device 2 installed on the inner side of the sealing cover 1 will sample the grain below. Specifically: the drive mechanism 22 drives the sampling tube 21 to move vertically downwards, and the sampling tube 21 is vertically and continuously inserted into the grain pile. Under continuous pressure, the grain is forced into the sampling tube 21 through the grain guide 211. During the continuous insertion, the grain in the sampling tube 21 is continuously squeezed upwards, eventually causing the grain to sequentially enter multiple storage bins 23. Then, the drive mechanism 22 drives the sampling tube 21 to move upwards and retract, completing the sampling.

[0035] Through the above-mentioned special scientific design, it has the following technical advantages:

[0036] First, the grain storage container of this utility model has a high degree of integration. It not only has a sampling port and a sealing cover 1, but also integrates a sampling device 2. When not sampling, the sampling device 2 is sealed inside the grain storage container. When sampling is required, the sealing cover 1 needs to be opened to carry out the sampling operation, which completely avoids the drawbacks of existing technologies that require manual carrying of sampling tools, fixed storage, and transportation of sampling tools.

[0037] Secondly, the grain storage container of this utility model has a high degree of automation. During sampling operations, the sealing cover 1 needs to be opened, and the sampling device 2 can automatically sample, instead of manually reaching into the container to take samples. This makes the sampling operation convenient and quick, with high work efficiency, greatly reducing the amount of labor and avoiding the risk of accidents.

[0038] Third, the grain storage container of this utility model has multiple sample storage compartments 23 set along the height direction of the sampling tube 21, and multiple samples can be sampled by repeatedly inserting it vertically downwards. It can sample a large amount of grain at one time and collect a large number of samples. It can also achieve grain sampling at different heights and positions, which facilitates subsequent analysis of multiple samples and greatly improves the effectiveness and scientific nature of grain testing and monitoring.

[0039] In this embodiment, the drive mechanism 22 includes a swing rod 221, a mounting rod 223, and a motor assembly 222. The motor assembly 222 is connected to the sealing cover 1 via the mounting rod 223. One end of the swing rod 221 is connected to the drive end of the motor assembly 222, and the other end is hinged to the top of the sampling tube 21. The motor assembly 222 is a mature existing product with its own reducer. By driving the forward and reverse rotation of the motor assembly 222, the swing rod 221 can move up and down, thereby driving the sampling tube 21 to move up and down. Of course, in other embodiments, other drive mechanisms 22 can also be provided, such as telescopic hydraulic cylinders or telescopic pneumatic cylinders, which are arranged vertically, with the telescopic drive end connected to the top of the sampling tube 21. They can also drive the sampling tube 21 to move up and down repeatedly, and all of these should fall within the protection scope of this utility model. The mounting rod 223 extends the installation distance and extends into the box, making it easier for the sampling tube 21 to be as close as possible to the grain, facilitating the sampling operation.

[0040] In this embodiment, an extension rod assembly 11 is fixed to the inner side of the sealing cover 1. The extension rod assembly 11 is detachably connected to the drive mechanism 22 for removing the sampling device 2 after sampling. The extension rod assembly 11 includes a vertical rod 111 perpendicular to the sealing cover 1 and a horizontal rod 112 perpendicularly connected to the bottom of the vertical rod 111. The end of the horizontal rod 112 is provided with a threaded part, and the end of the mounting rod 223 is provided with a fixing hole for the threaded part to pass through and be fixed by a nut. After the sealing cover 1 is opened, the horizontal rod 112 extends downward and into the box, making it easier for the sampling tube 21 to be as close as possible to the grain, facilitating the sampling operation. After the sealing cover 1 is closed, the vertical rod 111 extends to the side, creating an installation space, allowing the sampling device 2 to be flipped and folded together with the sealing cover 1, so that the flipped sampling device 2 will not collide with the sealing cover 1 or the top surface of the box. After sampling is completed, the sampling device 2 can be removed by loosening the nut, and then the sample can be collected by emptying the container.

[0041] In this embodiment, the grain guiding part 211 includes an inclined shovel with a side opening. A movable base plate 212 that can be flipped up and down is hinged to the bottom of the opening of the inclined shovel. A vertical screw 213 is provided on the movable base plate 212 for adjusting the inclination angle of the movable base plate 212 by rotating the screw 213. The design of the inclined shovel serves two purposes: first, it creates a guiding effect, facilitating the rapid entry of grain into the sampling tube 21; second, it increases the opening area of ​​the sampling tube 21, making it easier for grain from different positions to enter the sampling tube 21. Of course, depending on the humidity and type of stored grain (such as the grain size of different rice grains), the screw 213 can be rotated to raise or lower the movable base plate 212, thereby adjusting the speed at which the grain enters the sampling tube 21 by adjusting the inclination angle of the movable base plate 212.

[0042] In this embodiment, multiple transverse support ribs 214 are provided at the side opening of the tilting shovel. The multiple support ribs 214 are arranged at intervals, which can effectively support the tilting shovel with a large opening.

[0043] In this embodiment, each opening of the sampling tube 21 connected to each sample storage bin 23 is equipped with a fence assembly 3 to slow down the speed at which grain enters the sample storage bin 23. The design of the fence assembly 3 allows the grain to pass through the fence spacing and enter the sample storage bin 23, while slowing down the entry speed. This further ensures that during continuous insertion, the grain in the sampling tube 21 is continuously squeezed and surges upward, ultimately allowing the grain to enter multiple sample storage bins 23 sequentially.

[0044] In this embodiment, the sampling tube 21 is provided with a plurality of observation holes 215 with a diameter smaller than that of the grain grains, for observing the condition of the grain inside the sampling tube 21.

[0045] In this embodiment, each sample storage compartment 23 has a sampling port on its side wall, and a movable locking cover 231 is provided at the sampling port for pouring out the grain sample collected in the sample storage compartment 23 after opening. In this embodiment, the locking cover 231 is detachably locked to the side wall of the sample storage compartment 23 by screws.

[0046] In this embodiment, the sealing cover 1 is provided with a locking assembly 12 for sealing and locking the sealing cover 1. A detachable battery assembly 13 is also provided on the inner side of the sealing cover 1, and a switch assembly is provided on the outer side of the sealing cover 1. The sampling device 2 is electrically connected to both the switch assembly and the battery assembly 13. The battery assembly 13 provides power to the switch assembly and the sampling device 2, and can be removed for charging independently. After opening the sealing cover 1, operating the switch assembly will drive the sampling device 2 to perform the sampling operation.

[0047] In this embodiment, a sealing element is also provided on the contact surface between the sealing cover 1 and the grain storage container. The sealing element includes, but is not limited to, a rubber ring and a silicone ring.

[0048] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
