Description

Technical Field

[0001] This utility model belongs to the technical field of automotive sampling machine components, specifically a sampling head structure for a gantry-type automotive sampling machine. Background Technology

[0002] A gantry truck sampler is a coal sampling device that mainly consists of a feeding system, a sample grading system, a sampling system, and a control system. When sampling coal on a train, the train is first driven into the gantry sampler, then the sampling head is inserted into the coal in the cargo box, and the sampling system is started to collect the sample. Common sampling systems typically use a screw conveyor to form the sample, and the entire screw conveyor sampling component, also known as the sampling head, is one of the most important components of the gantry sampler.

[0003] In the existing technology, the sampling head structure of a gantry-type vehicle sampling machine with announcement number CN222895916U can form a horizontal limit between the cover and the first sleeve by inserting the set plug strip and the rectangular plug. Then, by using the insertion between the transverse slot and the transverse locking head, a vertical limit can be formed between the cover and the first sleeve, thereby completing the assembly and fixation of the two. However, in use, the protective hollow rod of the auger is usually disassembled and installed directly by disassembling the components. This makes it impossible to flexibly adjust and quickly lock the height of the protective hollow rod of the sampling head. As a result, the height of the protective hollow rod cannot be flexibly adjusted according to the material depth or sampling requirements, which limits the adaptability of the sampling operation. The fixed structure needs to be repeatedly disassembled and installed, which increases the complexity of operation and time cost. Moreover, frequent disassembly can easily lead to component wear, affecting the structural stability and sealing, and ultimately reducing sampling efficiency and equipment lifespan. To address these issues, we provide a sampling head structure for a gantry-type vehicle sampling machine. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of flexible adjustment and quick locking of the height of the hollow rod in the sampling head protection, as well as the quick disassembly of the sampling head, a sampling head structure for a gantry-type vehicle sampling machine is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A sampling head structure for a gantry-type vehicle sampling machine includes: The protective shell has first sliding grooves on both sides, a first mounting frame is fixedly installed on the upper end of the protective shell, and fixing bolts are threaded to both sides of the first mounting frame. The protective shell has a groove inside. A disassembly assembly, installed at the inner top of the groove, is used for disassembling and maintaining the sampling head.

[0006] Preferably, the disassembly assembly includes: A first motor is bolted to the top of the groove. The output end of the first motor is splined to a first rotating rod. A turntable is fixedly mounted at one end of the first rotating rod. A first limiting block is fixedly mounted on the surface of the turntable.

[0007] Preferably, the surface of the first limiting block is connected to a second mounting frame via a first limiting groove, and a first slider is fixedly mounted on both sides of the second mounting frame, the first slider slidingly adapting to the first sliding groove.

[0008] Preferably, it further includes: A sampling component is installed at the lower end of the second mounting frame and is used to sample materials.

[0009] Preferably, the sampling component includes: A connecting frame is bolted to the lower end of the second mounting frame. A second motor is bolted inside the connecting frame. A second rotating rod is fixedly mounted on one end of the second motor. An auger is fixedly mounted on one end of the second rotating rod.

[0010] Preferably, it further includes: A protective adjustment component is installed at the lower end of the connecting frame and is used to adjust the height of the protective hollow rod.

[0011] Preferably, the protective adjustment component includes: The sampling hollow rod is bolted to the lower end of the connecting frame. The sampling hollow rod has a circular groove inside, which is partially adapted to the auger. Second limiting blocks are fixedly installed on both sides of the sampling hollow rod. Multiple slots are opened on the surface of the second limiting blocks. The surface of the second limiting blocks is connected to the protective hollow rod through the second limiting slot.

[0012] Preferably, the inner wall of the protective hollow rod is provided with a first circular hole, and a frame is fixedly installed on both sides of the protective hollow rod. The inner wall of the frame is provided with a second sliding groove, and one side of the frame is provided with a second circular hole.

[0013] Preferably, a movable rod is provided inside the second circular hole, a pull plate is fixedly installed at one end of the movable rod, an adjusting plate is fixedly installed at the other end of the movable rod, and second sliders are fixedly installed on both sides of the adjusting plate, the second sliders being slidably adapted to the second sliding groove.

[0014] Preferably, an adjustment rod is fixedly installed at the other end of the adjustment plate, a plug is fixedly installed at one end of the adjustment rod, and the plug is partially adapted to the slot. A return spring is provided on the surface of the movable rod, one end of the return spring is fixedly connected to the inside of the frame, and the other end is fixedly connected to the adjustment plate.

[0015] The beneficial effects of this utility model are: The protective adjustment component of this utility model, by pulling the pull plate, causes the movable rod to move the adjustment plate, which in turn compresses the return spring. This, in turn, causes the adjustment plate to move the adjustment rod, which in turn moves the plug, allowing the plug to move out of the slot and release the restriction on the protective hollow rod. This adjusts the height of the protective hollow rod. Finally, the return spring's elasticity allows the plug to be inserted into the slot, fixing the protective hollow rod in place. This provides flexible adjustment and quick locking of the height of the sampling head's protective hollow rod, adapting to sampling needs at different depths while ensuring operational stability through the spring self-locking mechanism, significantly improving the adaptability and safety of sampling operations.

[0016] The disassembly assembly of this utility model uses an external power source connected to a first motor to drive a first rotating rod to rotate, which in turn drives a turntable to rotate, which in turn drives a first limiting block to rotate. This causes the first limiting block to move out of the first limiting groove, releasing the restriction on the second mounting frame. This allows for the rapid disassembly of the sampling head, facilitating subsequent maintenance and replacement, improving equipment maintenance efficiency, and reducing operational difficulty.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] Example 1: Please see Figures 1 to 6 This utility model provides a sampling head structure for a gantry-type vehicle sampling machine, comprising: The protective shell 1 has first sliding grooves 2 on both sides. A first mounting frame 3 is fixedly installed on the upper end of the protective shell 1, and fixing bolts are threaded to both sides of the first mounting frame 3. A groove is opened inside the protective shell 1. A disassembly component 4 is installed in the top of the groove for disassembling and maintaining the sampling head. A sampling component 5 is installed at the lower end of the second mounting frame 406 for sampling materials. A protective adjustment component 6 is installed at the lower end of the connecting frame 501 for adjusting the height of the protective hollow rod 605.

[0022] In this embodiment, the height of the sampling head protective hollow rod 605 is first flexibly adjusted and quickly locked by the protective adjustment component 6, which can not only adapt to the sampling needs of different depths, but also ensure the stability of the working state through the spring self-locking mechanism; secondly, the sampling component 5 enables uniform sampling of coal materials; and then the disassembly component 4 enables quick disassembly of the sampling head, which facilitates subsequent maintenance and replacement, improves equipment maintenance efficiency and reduces operation difficulty.

[0023] Example 2: Based on Embodiment 1, the disassembly component 4 is further disclosed.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the disassembly component 4 includes: A first motor 401 is bolted to the top of the groove. The output end of the first motor 401 is splined to a first rotating rod 402. A turntable 403 is fixedly mounted on one end of the first rotating rod 402. A first limiting block 404 is fixedly mounted on the surface of the turntable 403. A second mounting frame 406 is connected to the surface of the first limiting block 404 through a first limiting groove 405. First sliders 407 are fixedly mounted on both sides of the second mounting frame 406. The first sliders 407 slide and adapt to the first sliding groove 2.

[0025] In this embodiment, the first motor 401 is connected to an external power source to drive the first rotating rod 402 to rotate, which in turn drives the turntable 403 to rotate. The turntable 403 then drives the first limiting block 404 to rotate, causing the first limiting block 404 to move out of the first limiting groove 405 and release the restriction on the second mounting frame 406. This allows for the rapid disassembly of the sampling head, facilitating subsequent maintenance and replacement, improving equipment maintenance efficiency, and reducing operational difficulty.

[0026] Example 3: Based on Embodiment 1, sampling component 5 is further disclosed.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, sampling component 5 includes: A connecting frame 501 is bolted to the lower end of the second mounting frame 406. A second motor 502 is bolted inside the connecting frame 501. A second rotating rod 503 is fixedly mounted on one end of the second motor 502. An auger 504 is fixedly mounted on one end of the second rotating rod 503.

[0028] In this embodiment, the second motor 502 is connected to an external power source to drive the second rotating rod 503 to rotate, and the second rotating rod 503 drives the auger 504 to rotate, conveying the material into the sampling hollow rod 601. The sampling hollow rod 601 discharges the sampled material, thereby achieving the function of uniformly sampling the coal material.

[0029] Example 4: Based on Embodiment 1, a protective adjustment component 6 is further disclosed.

[0030] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the protective adjustment component 6 includes: A sampling hollow rod 601 is bolted to the lower end of the connecting frame 501. The sampling hollow rod 601 has a circular groove inside, which partially fits the auger 504. Second limiting blocks 602 are fixedly installed on both sides of the sampling hollow rod 601. Multiple slots 603 are formed on the surface of the second limiting blocks 602. A protective hollow rod 605 is connected to the surface of the second limiting blocks 602 through the second limiting slots 604. A first circular hole 606 is formed on the inner wall of the protective hollow rod 605. A frame 607 is fixedly installed on both sides of the protective hollow rod 605. A second sliding groove 608 is formed on the inner wall of the frame 607. A second circular hole 609 is formed on one side of the frame 607. A movable rod 610 is provided inside the two circular holes 609. A pull plate 611 is fixedly installed at one end of the movable rod 610, and an adjusting plate 612 is fixedly installed at the other end of the movable rod 610. Second sliders 613 are fixedly installed on both sides of the adjusting plate 612. The second sliders 613 are slidably adapted to the second slide groove 608. An adjusting rod 614 is fixedly installed at the other end of the adjusting plate 612. A plug 615 is fixedly installed at one end of the adjusting rod 614, and the plug 615 is partially adapted to the slot 603. A return spring 616 is provided on the surface of the movable rod 610. One end of the return spring 616 is fixedly connected to the inside of the frame 607, and the other end is fixedly connected to the adjusting plate 612.

[0031] In this embodiment, by pulling the pull plate 611, the movable rod 610 moves the adjusting plate 612, which in turn compresses the return spring 616. This, in turn, causes the adjusting plate 612 to move the adjusting rod 614, which in turn moves the plug 615, causing the plug 615 to move out of the slot 603. This releases the restriction on the protective hollow rod 605, adjusts the height of the protective hollow rod 605, and finally, the spring force of the return spring 616 causes the plug 615 to be inserted into the slot 603, fixing the protective hollow rod 605 in place. This achieves flexible adjustment and quick locking of the height of the sampling head's protective hollow rod 605, adapting to sampling needs at different depths while ensuring the stability of the working state through the spring self-locking mechanism, significantly improving the adaptability and safety of sampling operations.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
