Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, and in particular to a novel sampling device. Background Technology

[0002] Coal sampling is a crucial step in the coal testing process. From an error analysis perspective, if variance is used to quantify error, the sampling stage accounts for as much as 80% of the total error. In scenarios where coal is transported by train or truck, the traditional sampling method for deep coal seams usually involves manually removing the surface coal before sampling.

[0003] However, this traditional method has many drawbacks. Not only is the sampling efficiency low, but it also requires a lot of manpower and time. In addition, the labor intensity is high, which is a huge test of the physical strength of the sampling personnel. At the same time, there are certain safety hazards, and the personal safety of the sampling personnel cannot be fully guaranteed.

[0004] Therefore, this utility model provides a novel sampling device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a new type of sampling device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a novel sampling device, comprising an outer cylinder body,

[0007] An inner cylinder body is slidably installed inside the outer cylinder body;

[0008] The inner cylinder body is equipped with a spiral sampling mechanism, which includes a screw. The screw is rotatably connected to the inner cylinder body. Equally spaced spiral blades are fixedly connected to the outside of the screw. A sampling probe extending to the outside of the inner cylinder body is fixedly connected to one end of the bottom of the screw.

[0009] A drive adjustment mechanism is installed above the inner cylinder body. The drive adjustment mechanism includes a rotating rod. A handwheel is installed above the inner cylinder body. An anti-slip grip rod is fixedly connected to the top of the handwheel. A rotating rod is fixedly connected to the bottom of the handwheel's shaft. One bottom end of the rotating rod is fixedly connected to one top end of the screw.

[0010] In a preferred embodiment, the inner wall of the inner cylinder body is provided with an inner cylinder inner wall, and the inner wall of the inner cylinder can be filled with heat-insulating and sealing materials, thereby improving the sealing effect of the inner cylinder body when in use. The top of the inner cylinder body is provided with a first cavity, and the bottom of the inner cylinder body is provided with a second cavity. The design of the first cavity and the second cavity facilitates normal sampling and processing.

[0011] In a preferred embodiment, a collar is installed at the top of the inner cylinder body and outside the screw. A bearing is installed at the top of the collar. One end of the bottom of the rotating rod extends into the collar. The collar and bearing are used to limit the movement of the screw and the rotating rod. A fixing plate is installed at the connection between the screw and the sampling probe. Infrared sensors are installed at the top of the fixing plate and on both sides of the screw. The fixing plate facilitates the normal installation of the infrared sensors, which are used for remote monitoring and processing.

[0012] In a preferred embodiment, the handwheel has multiple mounting holes inside, and a limiting rod is installed inside the mounting holes. The top of the inner wall of the inner cylinder has multiple mounting slots that are installed in conjunction with the limiting rods. When the entire device is not in operation, the limiting rods are inserted into the mounting holes and mounting slots in sequence to further position the spiral sampling mechanism.

[0013] In a preferred embodiment, a control panel is installed on the outside of the inner cylinder body. The infrared sensor is electrically connected to the control panel. The control panel is used to control the operation of the infrared sensor, realizing unified management of the power equipment. The infrared sensor can be replaced with distance sensors, position sensors, or other devices, and can be flexibly replaced as needed, facilitating real-time monitoring and processing of on-site operations by remote personnel.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By configuring an inner cylinder body, an outer cylinder body, and a drive adjustment mechanism, the spiral sampling device is operated as follows: First, the outer cylinder body is placed stably above the material. Then, the inner cylinder body, equipped with the spiral sampling mechanism, is inserted into the outer cylinder body. It is then slowly and steadily inserted downwards. Once the inner cylinder body is inserted to a sufficient depth, the operator turns the handwheel clockwise. The material, under the force of the rotating spiral blades, gradually enters the inner cylinder body. Due to the extremely small gap between the spiral blades and the inner cylinder body, the material entering the inner cylinder body is effectively prevented from falling. Afterwards, the inner cylinder body is slowly lifted, and the handwheel is rotated in the opposite direction, causing the material in the inner cylinder body to pour into the material collection bucket, thus completing the sampling operation. This device innovatively employs a single... The spiral mechanical structure allows this tool to easily and freely penetrate deep into train carriages to accurately collect deep coal samples. Its flexibility and convenience are particularly outstanding in actual operation. It perfectly adapts to any type of train or truck carriage, regardless of its size or shape. Even when sampling the surface of a coal pile, it can obtain coal samples at full depth. During the descaling process, operators can flexibly and precisely control the thickness of the surface coal removed according to actual needs. This effectively avoids situations where the coal sample collected cannot accurately represent the true quality of the entire batch due to long-distance transportation or rain immersion, successfully filling a gap in the domestic market.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1-4As shown, this embodiment provides a technical solution: a novel sampling device, including an outer cylinder body 2, with an inner cylinder body 1 slidably installed inside the outer cylinder body 2; the outer cylinder body 2 is a columnar body with a diameter of 17cm and a height of 30cm, and a cover plate with an outer diameter of 33cm and an inner diameter of 17cm is installed on the upper and lower parts of the columnar body to facilitate the insertion of the inner cylinder body 1 into the outer cylinder body 1;

[0029] In this design, a spiral sampling mechanism is installed inside the inner cylinder body 1. The spiral sampling mechanism includes a screw 12, which is rotatably connected inside the inner cylinder body 1. Equally spaced spiral blades 13 are fixedly connected to the outside of the screw 12. A sampling probe 15 extending to the outside of the inner cylinder body 1 is fixedly connected to one end of the bottom of the screw 12. The inner cylinder body 1 is composed of a cylindrical barrel with a diameter of 17cm and a height of 100cm. A ring 35 is welded on the top of the barrel. A bearing 36 is installed inside the ring 35. The bearing 36 mainly serves to fix the screw 12, making it easier for the operator to rotate the screw 12 and extract representative samples more easily and conveniently.

[0030] In this design, a drive adjustment mechanism 3 is installed above the inner cylinder body 1. The drive adjustment mechanism 3 includes a rotating rod 31. A handwheel 32 is installed above the inner cylinder body 1. An anti-slip grip rod 33 is fixedly connected to the top of the handwheel 32. The rotating rod 31 is fixedly connected to the bottom of the shaft of the handwheel 32. One bottom end of the rotating rod 31 is fixedly connected to one top end of the screw 12. The screw sampling mechanism body is a 134cm long structure with a 100cm long spiral blade 13. The diameter of the spiral blade 13 is similar to that of the inner cylinder body 1. A handwheel 32 is installed at the rear end. By rotating the handwheel 32 clockwise, the spiral blade 13 is driven to rotate, thereby taking a representative sample from inside the material through the spiral structure.

[0031] Going further, such as Figures 1-4 As shown: In this solution, the inner wall of the inner cylinder body 1 is provided with an inner cylinder inner wall 11, and the inner cylinder inner wall 11 can be filled with heat insulation and sealing materials, thereby improving the sealing effect of the inner cylinder body 1 when in use.

[0032] In this design, a first cavity is provided at the top of the inner cylinder body 1, and a second cavity is provided at the bottom of the inner cylinder body 1. The design of the first and second cavities facilitates normal sampling and processing.

[0033] In this design, the handwheel 32 has multiple mounting holes 34 inside, and a limit rod is installed inside the mounting hole 34. The top of the inner wall 11 of the inner cylinder has multiple mounting slots 37 that are installed in conjunction with the limit rod. When the entire equipment is not in operation, the limit rod is inserted into the mounting hole 34 and the mounting slot 37 in sequence to further position the spiral sampling mechanism.

[0034] Furthermore, as shown in the figure Figure 3 As shown: In this scheme, a collar 35 is installed on the top of the inner cylinder body 1 and outside the screw 12. A bearing 36 is installed on the top of the collar 35. One end of the bottom of the rotating rod 31 extends into the collar 35. The collar 35 and the bearing 36 are used to limit the movement of the screw 12 and the rotating rod 31.

[0035] Going further, such as Figures 1-4 As shown, in this scheme, a fixing plate 14 is installed at the connection between the screw 12 and the sampling probe 15. Infrared sensors 16 are installed on the top of the fixing plate 14 and on both sides of the screw 12. The fixing plate 14 facilitates the normal installation of the infrared sensors 16, which are used for remote monitoring and processing.

[0036] In this solution, a control panel is installed on the outside of the inner cylinder body 1. The infrared sensor 16 is electrically connected to the control panel. The control panel is used to control the operation of the infrared sensor 16, realizing unified management of the power equipment.

[0037] Working principle:

[0038] like Figures 1-4 As shown:

[0039] By setting up an inner cylinder body 1, an outer cylinder body 2, and a drive adjustment mechanism 3, a collar 35 and a bearing 36 are used to limit the movement of the screw 12 and the rotating rod 31.

[0040] The outer cylinder body 2 is a column with a diameter of 17cm and a height of 30cm. The upper and lower parts of the column are each fitted with a cover plate with an outer diameter of 33cm and an inner diameter of 17cm to facilitate the insertion of the inner cylinder body 1 into the outer cylinder body 1.

[0041] The inner cylinder body 1 consists of a cylindrical barrel with a diameter of 17cm and a height of 100cm. A ring 35 is welded on the top of the barrel, and a bearing 36 is installed inside the ring 35. The bearing 36 mainly serves to fix the screw 12, making it easier for the operator to rotate the screw 12 and take out representative samples more easily and conveniently.

[0042] The main body of the screw sampling mechanism is a 134cm long structure with a 100cm long spiral blade 13. The diameter of the spiral blade 13 is similar to that of the inner cylinder body 1. A handwheel 32 is installed at the rear end. By rotating the handwheel 32 clockwise, the spiral blade 13 is driven to rotate, thereby taking a representative sample from inside the material through the spiral structure.

[0043] The inner wall 11 of the inner cylinder can be filled with heat-insulating and sealing materials to improve the sealing effect of the inner cylinder body 1 during use. The top of the inner cylinder body 1 is provided with a first cavity and the bottom of the inner cylinder body 1 is provided with a second cavity. The design of the first cavity and the second cavity facilitates normal sampling and processing.

[0044] The mounting plate 14 facilitates the normal installation of the infrared sensor 16, which is used for remote monitoring and processing.

[0045] The handwheel 32 has multiple mounting holes 34 inside, and a limit rod is installed inside the mounting hole 34. The top of the inner wall 11 of the inner cylinder has multiple mounting slots 37 that are installed in conjunction with the limit rod. When the whole equipment is not in operation, the limit rod is inserted into the mounting hole 34 and the mounting slot 37 in sequence to further position the spiral sampling mechanism.

[0046] The control panel is used to control the operation of the infrared sensor 16, realizing unified management of power equipment. The infrared sensor 16 can be replaced with distance sensors, position sensors, and other devices, and can be flexibly replaced as needed, facilitating remote staff to perform real-time monitoring and processing of on-site operations.

[0047] When using this spiral sampling device, first place the outer cylinder body 2 stably above the material. Then, insert the inner cylinder body 1, which is equipped with the spiral sampling mechanism, into the outer cylinder body 2. Next, slowly and steadily insert it downwards. When the inner cylinder body 1 is inserted to a sufficient depth, the operator turns the handwheel 32 clockwise. At this time, the material will gradually enter the inner cylinder body 1 under the force of the rotating spiral blade 13. Since the gap between the spiral blade 13 and the inner cylinder body 1 is extremely small, the material entering the inner cylinder body 1 can effectively avoid falling. Then, slowly lift the inner cylinder body 1 and rotate the handwheel 32 in the opposite direction to pour the material in the inner cylinder body 1 into the material collection bucket, thereby completing the sampling operation.

[0048] The beneficial effects of the technical solution of this invention are as follows:

[0049] 1. The screw sampling mechanism features a clever and lightweight portable design, making it easy for operators to carry and operate;

[0050] 2. This screw sampling mechanism can adapt to sampling work in train carriages and automobile carriages of various sizes and shapes;

[0051] 3. The screw sampling mechanism adopts a screw blade design, which can effectively ensure that the sample is not spilled and ensure the representativeness of the sample.

[0052] 4. During the surface removal sampling process, operators can use this new sampling mechanism to flexibly and accurately control the thickness of the surface coal to be removed according to actual needs. This effectively avoids situations where the coal sample cannot accurately represent the true quality of the entire batch of coal due to long-distance transportation or rain immersion, thus successfully filling a gap in the domestic market.

[0053] This innovative device employs a single-helix mechanical structure, allowing it to easily and freely penetrate deep into train carriages for precise sampling of deep coal. Its flexibility and convenience are particularly noteworthy in practical operation. It perfectly adapts to any type of train or truck carriage, regardless of size or shape. Furthermore, it can obtain full-depth coal samples even when sampling the surface of coal piles. During the descaling process, operators can flexibly and precisely control the thickness of the surface coal removed according to actual needs. This effectively prevents the collected coal samples from failing to accurately represent the true quality of the entire batch of coal due to long-distance transportation or rain immersion, successfully filling a gap in the domestic market.

[0054] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
