Description

Technical Field

[0001] This utility model relates to the technical field of coal samplers, and in particular to a multifunctional coal sampler. Background Technology

[0002] A coal sampler is a device specifically designed to collect representative samples from coal. Through a specific mechanical structure or automated device, it extracts a certain number of samples from a large quantity of coal material during production, transportation, storage, and processing, according to preset sampling standards, for subsequent coal quality analysis.

[0003] Currently, traditional coal samplers are often custom-made to a fixed size, which greatly limits their installation and use in different working environments. In the confined space of coal storage silos, large, fixed-size samplers are difficult to deploy flexibly; while when sampling deep into the coal pile is required, small samplers, due to their fixed length, cannot meet the sampling depth requirements, necessitating manual excavation, which increases operational risks and reduces sampling efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a multifunctional coal sampler. Through the setting of the installation mechanism and the fixing mechanism, not only is the stable installation of the sampler achieved, but the flexibility and applicability of the sampler are also improved. It can be adjusted according to different installation requirements to ensure the stable installation of the sampler.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a multifunctional coal sampler, comprising: a driving component, a sampling tube, a discharge tube, a sampling rod, and an installation mechanism. The sampling tube is installed at the bottom of the driving component, the discharge tube is fixed to the outer wall of the sampling tube, and the sampling rod is connected to the rotation shaft of the driving component. The installation mechanism includes an upper mounting base, a first spring, a fixing ball, a fixing ring, a lower mounting base, and a second spring. The upper mounting base is installed on the outer wall of the sampling rod, the first spring is sleeved inside the upper mounting base, the fixing ball is installed inside the upper mounting base, the fixing ring is installed inside the upper mounting base, the lower mounting base is installed inside the upper mounting base, the second spring is sleeved inside the lower mounting base, and a locking hole is provided on the outer wall of the lower mounting base.

[0007] In addition, the multifunctional coal sampler proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the sampling tube is equipped with a fixing mechanism on its exterior. The fixing mechanism includes a connecting tube, a pad, a fastener, a bolt, a fixing block, and a rotating shaft. The connecting tube is installed at the bottom of the sampling tube, the pad is fitted on the outer wall of the connecting tube, the fastener is fitted on the outer wall of the pad, the bolt is threaded to the fastener, and the bolt passes through the fastener and is connected to the fixing block. The rotating shaft is rotatably connected inside the fixing block.

[0009] Specifically, the outer wall of the upper mounting base is fitted with an anti-slip block.

[0010] Specifically, a handle is fixed to the outer wall of the sampling tube.

[0011] Specifically, a sealing ring is fitted on the outer wall of the connecting pipe.

[0012] Specifically, a washer is fitted on the outer wall of the bolt.

[0013] Compared with existing technologies, this utility model has the following advantages: This multifunctional coal sampler, through the design of its installation and fixing mechanisms, not only achieves stable installation but also improves its flexibility and applicability. The sampling rod is connected to the rotating shaft of the drive component, allowing the sampling tube to easily penetrate deep into the coal pile for sampling. The upper mounting seat, first spring, fixing ball, fixing ring, lower mounting seat, and second spring in the installation mechanism work together to adjust for different installation requirements, ensuring a stable installation of the sampler. Simultaneously, the connecting pipe, pad, fasteners, bolts, fixing block, and rotating shaft in the fixing mechanism further enhance the stability and reliability of the sampler, enabling it to be effectively used in various operating environments.

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] A multifunctional coal sampler according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown in the figure, a multifunctional coal sampler according to an embodiment of the present invention includes: a driving component 1, a sampling tube 2, a discharge tube 3, a sampling rod 6, and an installation mechanism 7.

[0024] The sampling tube 2 is installed at the bottom of the drive component 1, the discharge tube 3 is fixed to the outer wall of the sampling tube 2, the sampling rod 6 is connected to the rotation shaft of the drive component 1, and the mounting mechanism 7 includes an upper mounting base 71, a first spring 72, a fixed ball 73, a fixed ring 74, a lower mounting base 76, and a second spring 77.

[0025] The upper mounting base 71 is installed on the outer wall of the sampling rod 6, the first spring 72 is sleeved inside the upper mounting base 71, the fixing ball 73 is installed inside the upper mounting base 71, the fixing ring 74 is installed inside the upper mounting base 71, the lower mounting base 76 is installed inside the upper mounting base 71, the second spring 77 is sleeved inside the lower mounting base 76, and the outer wall of the lower mounting base 76 is provided with a locking hole 78.

[0026] The outer wall of the upper mounting base 71 is fitted with an anti-slip block 75.

[0027] Specifically, when it is necessary to increase the length of the sampling rod 6 in the sampler, the upper mounting base 71 is first separated from the lower mounting base 76, and then one end of the other sampling rod 6 is inserted into the lower mounting base 76. At this time, the fixing ball 73 is locked into the locking hole 78 of the lower mounting base 76 under the action of the first spring 72, realizing the quick connection of the sampling rod 6. The anti-sliding block 75 increases the stability of the sampling rod 6 during connection and prevents the sampling rod 6 from falling off during use.

[0028] In one embodiment of this application, such as Figure 3 As shown, a fixing mechanism 8 is provided on the outside of the sampling tube 2. The fixing mechanism 8 includes a connecting tube 81, a pad 82, a fastener 83, a bolt 84, a fixing block 86, and a rotating shaft 87. The connecting tube 81 is installed at the bottom of the sampling tube 2. The pad 82 is sleeved on the outer wall of the connecting tube 81. The fastener 83 is sleeved on the outer wall of the pad 82. The bolt 84 is threadedly connected to the fastener 83. The bolt 84 passes through the fastener 83 and is connected to the fixing block 86. The rotating shaft 87 is rotatably connected inside the fixing block 86.

[0029] A washer 85 is fitted on the outer wall of bolt 84.

[0030] Specifically, when it is necessary to connect and fix the connecting pipe 81 to the sampling pipe 2, first align the two pipes, then put the fixing mechanism 8 on the outer wall of the connecting pipe 81, then tighten the fastener 83 so that the pad 82 is tightly attached to the outer wall of the sampling pipe 2, then rotate the bolt 84 so that the bolt 84 passes through the fastener 83 and is tightly connected to the fixing block 86. At this time, turn the fixing block 86, and the fixing block 86 rotates around the rotating shaft 87, which drives the bolt 84 to pull the fastener 83 tight. The fastener 83 squeezes the pad 82, and the pad 82 generates friction on the sampling pipe 2, so as to achieve a tight connection between the sampling pipe 2 and the connecting pipe 81 and avoid shaking or falling off during the sampling process. The use of the pad 85 increases the service life of the fastener 83.

[0031] In one embodiment of this application, such as Figure 1 As shown, a handle 4 is fixed to the outer wall of the sampling tube 2.

[0032] Understandably, the handle 4 makes it easier for operators to move and transport the sampling tube 2, thus improving the ease of use of the sampler.

[0033] In one embodiment of this application, such as Figure 1 As shown, a sealing ring 5 is fitted on the outer wall of the connecting pipe 81.

[0034] Understandably, the sealing ring 5 increases the sealing at the connection between the connecting pipe 81 and the sampling pipe 2, preventing coal leakage during sampling and affecting the sampling results.

[0035] Working principle: During use, the operator starts the drive unit 1, which drives the sampling rod 6 to rotate. The sampling rod 6 drives the sampling tube 2 to penetrate into the coal for sampling. After sampling, the coal sample inside the sampling tube 2 is discharged through the discharge pipe 3 for subsequent analysis. When it is necessary to increase the length of the sampling rod 6 in the sampler, first separate the upper mounting base 71 from the lower mounting base 76, and then insert one end of the other sampling rod 6 into the lower mounting base 76. At this time, the fixing ball 73 is engaged in the locking hole 78 of the lower mounting base 76 under the action of the first spring 72, realizing the quick connection of the sampling rod 6. The anti-slip block 75 increases the stability of the sampling rod 6 during connection and avoids... If the sampling rod 6 falls off during use, and it is necessary to connect and fix the connecting tube 81 to the sampling tube 2, first align the two tubes, then put the fixing mechanism 8 on the outer wall of the connecting tube 81, then tighten the fastener 83 so that the pad 82 is tightly attached to the outer wall of the sampling tube 2, then rotate the bolt 84 so that the bolt 84 passes through the fastener 83 and is tightly connected to the fixing block 86. At this time, turn the fixing block 86, and the fixing block 86 rotates around the rotating shaft 87, which drives the bolt 84 to pull the fastener 83 tight. The fastener 83 squeezes the pad 82, and the pad 82 generates friction on the sampling tube 2, so as to achieve a tight connection between the sampling tube 2 and the connecting tube 81 and avoid shaking or falling off during the sampling process.
