Description

Technical Field

[0001] This utility model belongs to the field of coal testing, specifically relating to a sample receiving device for coal testing with an openable structure. Background Technology

[0002] The core purpose of coal sampling is to support multiple dimensions, including quality assurance, fair trade, environmental compliance, safe production, and scientific research. Simultaneously, by retaining samples, key indicators such as calorific value, ash content, sulfur content, and moisture can be measured to clarify the coal's combustion efficiency, pollutant emission potential, and industrial applicability. Coal mining companies can optimize mining plans through sampling, such as adjusting washing processes based on coal stratification; power companies can adjust boiler combustion parameters to improve energy efficiency.

[0003] In order to ensure sample diversity and improve sample reliability, multiple batches and multiple sample points are often used when sampling coal. Then, the collected samples are stored in different sample containers and locked. The sample containers are then transported to the manufacturer to be tested, the containers are opened, and samples are taken from inside the sample containers.

[0004] Currently, when taking samples, the sampling bucket lid is often opened manually. This method is inefficient. When using a machine to open the lid, there is a problem that the lid and bucket are too tightly closed and cannot be properly separated. This can cause the machine to drag the entire bucket, resulting in a safety accident. Therefore, there is an urgent need for a coal testing sampling device with a lid opening structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, which is that manually opening the sampling bucket lid is inefficient and that using a machine to open the lid can cause safety accidents because the lid and bucket are too tightly closed and cannot be properly separated, thus dragging the entire bucket with the opening machine. Therefore, this invention provides a coal testing sampling device with a lid opening structure.

[0006] To achieve the above-mentioned objectives, the technical solution of this utility model is: a coal testing sample receiving device with an openable structure, including a support frame, an electric turntable rotatably connected to the lower part of the support frame, a sample storage bucket assembly for storing coal samples on the electric turntable, an openable assembly on the support frame above the side of the electric turntable, and a control cabinet electrically connected to the openable assembly.

[0007] The opening assembly includes a linear motor fixedly installed on the upper part of the support frame. A guide rail is fixedly installed on the output end of the linear motor. An electric block that can move up and down along the guide rail is slidably arranged on the guide rail. Symmetrically arranged lifting components are installed on the side of the electric block facing the sample storage container assembly.

[0008] In the above-mentioned coal testing sample receiving device with an openable structure, the sample storage barrel assembly includes a barrel body, a barrel cover is provided on the upper part of the barrel body, a connecting column is fixedly connected to the upper part of the barrel cover, and a shell with a diameter larger than the connecting column is provided at the top of the connecting column.

[0009] In the aforementioned coal testing sample receiving device with an openable structure, the electric turntable has more than one hole for accommodating the barrel. At the same time, positioning marks corresponding to the holes are installed on the side of the electric turntable, and a position sensor for identifying the positioning marks is installed on one side of the support frame.

[0010] In the above-mentioned coal testing sample receiving device with an open cover structure, a connecting frame is installed on the front and back sides of the two lifting components, and a controller is fixedly installed on the upper part of the connecting frame. The controller is equipped with a transmitting coil inside.

[0011] In the above-mentioned coal testing sample receiving device with an openable structure, the supporting component includes side plates installed on the connecting frame, and a support plate is integrally formed on the opposite surfaces of the two side plates, and a retaining strip is integrally formed on the upper part of each side plate.

[0012] In the above-mentioned coal testing sample receiving device with an openable structure, more than one circular slot is provided on the opposite sides of the two card strips, and slots for accommodating the card strips are provided on both sides of the electric block. Mounting holes are provided on the electric block, and the mounting holes are divided into threaded parts and unthreaded parts. The unthreaded parts of the two mounting holes are arranged opposite each other.

[0013] In the above-mentioned coal testing sample receiving device with an open cover structure, the threaded portions of the two mounting holes are threadedly connected with bolts, and springs are fixedly connected to the opposite surfaces of the two bolts. Limiting balls are fixedly connected to the ends of the two springs away from the corresponding bolts, and the springs are disposed in the unthreaded portions of the corresponding mounting holes.

[0014] Compared with the prior art, the coal testing sample receiving device with an openable structure of this utility model has at least the following beneficial effects:

[0015] 1. This utility model discloses a coal testing sample receiving device with an opening structure. By setting up the opening component, the support plate in the opening component is controlled by the control cabinet to move, causing the barrel lid to move and detach from the upper part of the barrel body, thus realizing the opening of the barrel body. The operation is simple. When the barrel body and the barrel lid are too tightly fitted, and the support plate moves the entire sample storage barrel assembly, the limiting ball is subjected to excessive force and disengages from the circular slot, causing the lifting component to detach from the electric block. While the lifting component moves normally, the sample storage barrel assembly does not move, avoiding the safety accident caused by the support plate lifting the sample storage barrel assembly. This improves the safety of the opening component during the opening process. At the same time, the compression of the spring can be adjusted according to the coal content in the sample storage barrel assembly to adjust the maximum lifting force of the lifting component. This avoids the phenomenon that when the coal content in the sample storage barrel assembly is too low, the lifting component lifts the sample storage barrel assembly but still does not detach from the electric block, thus expanding the applicability of the opening component.

[0016] 2. The coal testing sample receiving device with an openable structure of this utility model, by setting the lifting component to be detachable on the electric block, allows the limiting ball to be re-engaged into the circular slot by the bolt after the lifting component is detached from the electric block, thereby realizing the cyclic use of the lifting component and improving its service life.

[0029] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the coal testing sample receiving device with an openable structure according to this utility model.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] This embodiment discloses a coal testing sample receiving device with an opening structure. By setting up the opening assembly 6, the support plate 664 in the opening assembly 6 is controlled by the control cabinet 5 to move, causing the barrel lid 42 to move away from the upper part of the barrel body 41, thus opening the barrel body 41. When the barrel body 41 and the barrel lid 42 are too tightly fitted, and the support plate 664 moves the entire sample storage barrel assembly 4, the limiting ball 68 experiences excessive force and disengages from the circular groove 661, causing the lifting component 66 to disengage from the electric block 6. 3. While the lifting component 66 moves normally, the sample storage container assembly 4 does not move, preventing the support plate 664 from lifting the sample storage container assembly 4 and causing a safety accident. This improves the safety of the opening component 6 during the opening process. Simultaneously, the compression of the spring 69 can be adjusted according to the coal content inside the sample storage container assembly 4 to adjust the maximum lifting force of the lifting component 66. This prevents the phenomenon where, when the coal content inside the sample storage container assembly 4 is too low, the lifting component 66 lifts the sample storage container assembly 4 but remains attached to the electric block 63, thus expanding the applicability of the opening component 6. (Refer to...) Figures 1-7 The system mainly includes a support frame 1, with an electric turntable 2 rotatably connected to the lower part of the support frame 1. A sample storage container assembly 4 for storing coal samples is mounted on the electric turntable 2. A control cabinet 5 is fixedly connected to the upper surface of the support frame 1, and a lid-opening assembly 6 for opening the sample storage container assembly 4 is electrically connected to the lower part of the control cabinet 5. The control cabinet 5 uses a conventional industrial electrical control cabinet, typically implemented using a PLC, which is a conventional and mature industrial control method. Furthermore, this control method is not the focus of this invention; therefore, the control cabinet 5 will not be described in detail here.

[0032] like Figure 1 , Figure 2 and Figure 5 It is known that the sample storage container assembly 4 includes a container body 41, a container cover 42 is provided on the upper part of the container body 41, a connecting post 45 is fixedly connected to the upper part of the container cover 42, a housing 43 with a diameter larger than the connecting post 45 is provided at the top of the connecting post 45, a coil 46 is fixedly installed inside the housing 43, an identification cover 44 is fixedly installed on the upper part of the housing 43, an RFID tag (the RFID tag has a built-in passive chip, which is an existing device and will not be described in detail) is provided inside the housing 43, and the coil 46 is electrically connected to the passive chip built into the RFID tag.

[0033] like Figure 1It is known that the electric turntable 2 has more than one hole for accommodating the barrel 41. Simultaneously, positioning marks 3 are installed on the side of the electric turntable 2, corresponding to each hole. A position sensor 7 for identifying the positioning marks 3 is installed on one side of the support frame 1. The position sensor 7 is a conventional sensor, and its main purpose is: when the electric turntable 2 rotates, the position sensor 7 detects the arrival of the positioning mark 3 and stops the rotation of the electric turntable 2, achieving a fixed-angle rotation of the electric turntable 2. This ensures that the position of the sample storage barrel assembly 4, to be opened, remains constant, facilitating subsequent opening by the lid-opening assembly 6. It should be noted that when the position sensor 7 detects the positioning mark 3, firstly, it stops the rotation of the electric turntable 2; secondly, it transmits an electrical signal to the inside of the control cabinet 5, and the control cabinet 5 activates the lid-opening assembly 6 to open the lid.

[0034] like Figure 3 and Figure 7 It is understood that the opening assembly 6 includes a linear motor 61 fixedly installed on the upper part of the support frame 1. A guide rail 62 is fixedly installed on the output end of the linear motor 61. An electric block 63 that can move up and down along the guide rail 62 is slidably arranged on the guide rail 62. Symmetrically arranged lifting members 66 are installed on the side of the electric block 63 facing the sample storage container assembly 4. A connecting frame 65 is installed on the front and back of the two lifting members 66. A controller 64 is fixedly installed on the upper part of the connecting frame 65. A transmitting coil is provided inside the controller 64. When the controller 64 approaches the coil 46, the transmitting coil in the controller 64 is energized to form a magnetic field. The transmitting coil inside the controller 64 provides power to the coil 46 through the magnetic field. Its wireless charging method is a common electromagnetic principle, which will not be elaborated here. After the coil 46 generates power, it provides power to the passive chip built into the RFID tag and sends a signal to the reader. The reader decodes the signal and sends it to the database for storage.

[0035] It should be noted that: controller 64 is the aforementioned reader / writer, and the database uses a relational model to organize data, storing data in rows and columns, with data linked through foreign keys, etc. Since the database is existing technology, it will not be described in detail.

[0036] By setting an RFID tag in each of the sample storage barrel components 4, when the controller 64 opens the sample storage barrel component 4, a signal is sent to the database, and the sampling personnel can directly learn about the coal mining situation inside the sample storage barrel component 4 (such as mining location, mining time, etc.) from the database.

[0037] like Figure 3It is understood that the lifting component 66 includes side plates 663 mounted on the connecting frame 65. Support plates 664 are integrally formed on the opposing surfaces of the two side plates 663, and locking strips 662 are integrally formed on the upper part of each side plate 663. When it is necessary to lift the bucket lid 42 away from the upper part of the bucket body 41, after the control cabinet 5 receives the electrical signal from the position sensor 7, the control cabinet 5 starts the electric block 63 to move downwards a certain distance. Subsequently, it controls the linear motor 61 to start, driving the guide rail 62 towards the sample storage bucket assembly 4, causing the lifting component 66 to move to the lower part of the housing 43. At this moment, the lifting component 66 is directly above the coil 46. The linear motor 61 and the lifting component 66 are controlled to be turned off for a period of time. Subsequently, by starting the linear motor 61 and the electric block 63 to move in opposite directions simultaneously, the lid opening assembly 6 drives the bucket lid 42 to move obliquely, thus opening the sample storage bucket assembly 4.

[0038] like Figure 3 and Figure 6 It is known that the two card strips 662 have more than one circular slot 661 on their opposite sides, and the electric block 63 has slots 67 on both sides to accommodate the card strips 662. The electric block 63 has mounting holes 611, which are divided into threaded and unthreaded parts. The unthreaded parts of the two mounting holes 611 are arranged opposite each other. The threaded parts of the two mounting holes 611 are threadedly connected to bolts 610. The opposite surfaces of the two bolts 610 are fixedly connected to springs 69. The ends of the two springs 69 away from the corresponding bolts 610 are fixedly connected to limit balls 68. The springs 69 are arranged in the unthreaded parts of the corresponding mounting holes 611. The depth of the circular groove 661 is 1 / 3 of the diameter of the limiting ball 68. Setting the depth of the circular groove 661 to 1 / 3 of the diameter of the limiting ball 68 prevents the limiting ball 68 from getting too stuck inside the circular groove 661. When the side plate 663 is subjected to excessive force, the limiting ball 68 cannot stably detach from the interior of the circular groove 661. In other words, it ensures that when the side plate 663 is subjected to excessive force, the limiting ball 68 can smoothly detach from the interior of the circular groove 661, thereby protecting the side plate 663.

[0039] By making the lifting component 66 detachable from the electric block 63, after the lifting component 66 is detached from the electric block 63, the limiting ball 68 can be driven to re-enter the circular slot 661 by the bolt 610, thereby realizing the cyclic use of the lifting component 66 and improving its service life.

[0040] The working principle of the coal testing sample receiving device with an openable structure of this utility model is as follows:

[0041] When it is necessary to use this device to open the lid;

[0042] First, multiple sample storage container assemblies 4 are placed sequentially on the electric turntable 2. Then, the electric turntable 2 is started via an external power source. The electric turntable 2 drives the positioning marker 3 to rotate. After the positioning marker 3 rotates to the position of the position sensor 7, the electric turntable 2 stops rotating. The position sensor 7 triggers the lid opening assembly 6 via the control cabinet 5, starting the linear motor 61. The linear motor 61 drives the guide rail 62 to move, and the movement of the guide rail 62 drives the electric block 63 to move. The movement of the electric block 63 causes the mounting hole 611 to move, the movement of the mounting hole 611 causes the bolt 610 to move, the movement of the bolt 610 causes the spring 69 to move, the movement of the spring 69 causes the limiting ball 68 to move, the movement of the limiting ball 68 causes the circular slot 661 to move, the movement of the circular slot 661 causes the locking strip 662 to move, the movement of the locking strip 662 causes the side plate 663 to move, and the movement of the side plate 663 causes the support plate 664 to move.

[0043] When it is necessary to install the lifting member 66 on the electric block 63;

[0044] First, the lifting member 66 is moved by an external force. When the lifting member 66 moves and the circular slot 661 moves to coincide with the corresponding mounting hole 611, the bolt 610 is moved by an external tool. The bolt 610 moves and the limiting ball 68 moves and the limiting ball 68 moves to press the circular slot 661.
