Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of heat tracing sampling technology, and more specifically to a low-temperature anti-icing spiral sampling head with heat tracing function. Background Technology
[0002] The anti-icing spiral sampling head is a professional sampling device designed for cold environments. By combining a spiral structure with heat tracing technology, it solves the sampling problem caused by material freezing at low temperatures. It is suitable for multiple fields such as coal, photovoltaic, and chemical industries. It can effectively ensure the flowability of the sampled material and prevent the sampled material from freezing during transportation.
[0003] Traditional equipment often uses fixed-power heating cables, which cannot dynamically adjust the heating power according to the ambient temperature. For example, in environments below -10℃, the sleeve wall temperature may fall below the freezing point due to insufficient heating power, causing the material to freeze. In extremely cold regions (such as Heilongjiang and northeastern Inner Mongolia), traditional heating systems cannot even maintain basic anti-icing requirements, causing the equipment to completely malfunction. In traditional anti-icing devices, the heating cable is placed inside the sampling device, which may cause the heating temperature to directly contact the sampled material, resulting in the melting of moisture in the material and affecting the accuracy of the sampling.
[0004] A search revealed Chinese Patent Publication No. CN201420139393.X, which discloses a low-temperature anti-icing spiral sampling head. The head includes a sampling head body, with a spiral drill rod at one end and a cutter head at the lower end. The spiral drill rod is characterized by having a sleeve, inside which is a constant-temperature heating cable evenly distributed in a spiral pattern. The constant-temperature heating cable passes through the sleeve and is connected to an external power source.
[0005] When the device in the aforementioned patent is used for sampling in a low-temperature environment, the constant temperature tracing cable is installed inside the sleeve. This causes the tracing cable to come into direct contact with the sampled material. The operation of the constant temperature tracing cable will heat the sampled material, which will affect the quality of the material and cause inaccurate detection of the sampled material. In addition, when the device in the aforementioned patent is used for sampling, the sampled material can only be discharged by reversing the auger rod, which cannot effectively achieve continuous sampling. Utility Model Content
[0006] The purpose of this invention is to provide a low-temperature, anti-icing spiral sampling head with heat tracing function. In this device, the heat tracing cable is installed on the fixed shell and the protective shell, which effectively ensures the temperature variation effect of the sampling head and the sampling device. During sampling, the spiral blades are rotated by a drive motor, which transfers the sampled material to the sample storage hood. When the spiral blades rotate, the semi-circular gear on the output shaft of the drive motor meshes with the gear ring, thereby effectively driving the rotating shell to rotate. When the second discharge port on the rotating shell coincides with the first discharge port, the material in the sample storage hood is discharged between the two annular plates, which can effectively achieve the effect of continuous sampling, thus solving the problems of the aforementioned background technology.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A low-temperature anti-icing spiral sampling head with heat tracing function includes a sampling component; the sampling component includes a fixed shell; a sample storage cover is fixedly installed at one end inside the fixed shell; a U-shaped first discharge port is opened at the bottom of the sample storage cover; a rotating shell is fitted at the end of the fixed shell away from the sample storage cover; the inner diameter of the rotating shell is the same as the outer diameter of the sample storage cover; two annular plates are integrally formed on the outside of the rotating shell; the diameter of the annular plates is the same as the inner diameter of the fixed shell.
[0009] The rotating shell has a toothed ring integrally formed at the end away from the sample storage cover; the rotating shell has a second discharge port with the same structure as the sample storage cover on its side wall; the fixed shell has a movable door installed on its bottom side wall; the movable door is located between two annular plates.

[0012] As a further technical solution of this utility model, the heating component is installed on the top of the fixing component; the fixing component includes a fixing frame; one side of the fixing frame is fixedly installed with the fixing shell; the extension plate on the fixing frame is fixedly installed with the side wall of the mounting tube.
[0013] As a further technical solution of this utility model, a drive motor is fixedly installed on the side of the fixed frame away from the fixed shell; the output shaft of the drive motor passes through the fixed frame and a semi-circular gear is fixedly installed thereon; the semi-circular gear meshes with a gear ring; the end of the output shaft of the drive motor is fixedly installed with the rotating shaft of the spiral blade.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. In use, the protective shell with an opening is inserted into the material to be sampled. The sampled material comes into contact with the spiral blades through the opening. The rotation of the spiral blades transfers the material to the sample storage hood. During the sampling process, the controller heats the heating cable through wires. The heating cable is attached to the surface of the protective shell and the fixed shell, thereby transferring the heat in the heating cable to the inside of the protective shell and the fixed shell, thus preventing the sampled material from freezing.
[0017] 2. In the sampling process of this utility model, during the process of driving the spiral blades to rotate, the semi-circular gear installed on the output shaft of the drive motor meshes with the gear ring at the end of the rotating shell, thereby effectively realizing the rotation of the rotating shell along the fixed shell through the annular plate. During the rotation of the rotating shell, when the second discharge port opened on the rotating shell coincides with the first discharge port opened on the side wall of the sample storage hood, the material inside the sample storage hood is discharged to the outside of the rotating shell through the first discharge port and the second discharge port and is located between the two annular plates. By opening the movable door opened at the bottom of the fixed shell, the material can be removed, thus effectively achieving continuous sampling.
[0018] 3. In this utility model, during sampling, the temperature in the sampling head and sampling components can be increased or decreased by manually controlling the controller, thereby effectively ensuring that the internal temperature of the sampling head is controlled within a suitable range during sampling, thus ensuring the quality and efficiency of sampling.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-9In this embodiment of the present invention, the low-temperature anti-icing spiral sampling head with heat tracing function includes a sampling component 3; the sampling component 3 includes a fixed shell 30; a sample storage cover 32 is fixedly installed at one end inside the fixed shell 30; a U-shaped first discharge port 37 is opened at the bottom of the sample storage cover 32; a rotating shell 33 is fitted inside the fixed shell 30 at the end away from the sample storage cover 32; the inner diameter of the rotating shell 33 is the same as the outer diameter of the sample storage cover 32; two annular plates 34 are integrally provided on the outside of the rotating shell 33; the diameter of the annular plates 34 is the same as the inner diameter of the fixed shell 30.
[0031] The rotating shell 33 has a toothed ring 35 integrally formed at the end away from the sample storage cover 32; the rotating shell 33 has a second discharge port 36 with the same structure as the sample storage cover 32 on its side wall; the fixed shell 30 has a movable door 31 installed on its bottom side wall; the movable door 31 is located between two annular plates 34.
[0032] The sampling head 2 is fixedly installed at one end of the fixed shell 30; the sampling head 2 includes a protective shell 20; the protective shell 20 is arranged in a stepped shape; the protective shell 20 has multiple openings 23 at the end away from the sampling component 3; a spiral blade 22 is installed inside the protective shell 20, and the spiral blade 22 also penetrates the sample storage cover 32 and the rotating shell 33.
[0033] By adopting the above technical solution, during use, the end of the protective shell 20 with the opening 23 is inserted into the material to be sampled. The sampled material comes into contact with the spiral blade 22 through the opening 23. Through the rotation of the spiral blade 22, the material is transferred to the sample storage hood 32. During the sampling process, the controller 50 heats the heating cable 21 through the wire 51. The heating cable 21 is attached to the surface of the protective shell 20 and the fixed shell 30, thereby transferring the heat in the heating cable 21 to the inside of the protective shell 20 and the fixed shell 30 through heat transfer, thus preventing the sampled material from freezing.
[0034] In this embodiment, the sampling head 2 further includes two sets of symmetrically arranged heat tracing cables 21; the heat tracing cables 21 are fitted and installed in close contact with the protective shell 20 and the fixed shell 30; one end of the heat tracing cable 21 is fixedly installed with the protective shell 20; the other end is connected to the heating component 5; the heating component 5 includes a controller 50; the controller 50 has wires 51 connected to the two sets of heat tracing cables 21 symmetrically arranged on both sides.
[0035] In this embodiment, the heating component 5 is installed on the top of the fixing component 4; the fixing component 4 includes a fixing frame 40; one side of the fixing frame 40 is fixedly installed with the fixing shell 30; the extension plate on the fixing frame 40 is fixedly installed with the side wall of the mounting tube 1.
[0036] By adopting the above technical solution, during the sampling process, the drive motor 41 drives the spiral blade 22 to rotate. During the sampling process, the semi-circular gear 42 installed on the output shaft of the drive motor 41 meshes with the gear ring 35 at the end of the rotating shell 33, thereby effectively realizing the rotation of the rotating shell 33 along the fixed shell 30 through the annular plate 34. During the rotation of the rotating shell 33, when the second discharge port 36 opened on the rotating shell 33 coincides with the first discharge port 37 opened on the side wall of the sample storage cover 32, the material inside the sample storage cover 32 is discharged to the outside of the rotating shell 33 through the first discharge port 37 and the second discharge port 36, and is located between the two annular plates 34. By opening the movable door 31 opened at the bottom of the fixed shell 30, the material can be removed. This can also effectively achieve continuous sampling.
[0037] Furthermore, a drive motor 41 is fixedly installed on the side of the fixed frame 40 away from the fixed housing 30; the output shaft of the drive motor 41 passes through the fixed frame 40 and a semi-circular gear 42 is fixedly installed thereon; the semi-circular gear 42 meshes with the gear ring 35; the end of the output shaft of the drive motor 41 is fixedly installed with the rotating shaft of the spiral blade 22.
[0038] In this embodiment, the side of the mounting bracket 40, on which the drive motor 41 is installed, away from the mounting shell 30 is fixedly installed with the mounting tube 1; the bottom of the mounting tube 1 is fixedly installed with the mobile device.

[0040] The working principle of this utility model is as follows: When in use, the end of the protective shell 20 with the opening 23 is inserted into the material to be sampled. The sampled material comes into contact with the spiral blade 22 through the opening 23. Through the rotation of the spiral blade 22, the material is transferred to the sample storage hood 32. During the sampling process, the controller 50 heats the heating cable 21 through the wire 51. The heating cable 21 is attached to the surface of the protective shell 20 and the fixed shell 30, so that the heat in the heating cable 21 is transferred to the inside of the protective shell 20 and the fixed shell 30 through heat transfer, thus preventing the sampled material from freezing.
[0041] During the sampling process, the drive motor 41 drives the spiral blade 22 to rotate. During the sampling process, the semi-circular gear 42 installed on the output shaft of the drive motor 41 meshes with the gear ring 35 at the end of the rotating shell 33, thereby effectively realizing the rotation of the rotating shell 33 along the fixed shell 30 through the annular plate 34. During the rotation of the rotating shell 33, when the second discharge port 36 opened on the rotating shell 33 coincides with the first discharge port 37 opened on the side wall of the sample storage cover 32, the material inside the sample storage cover 32 is discharged to the outside of the rotating shell 33 through the first discharge port 37 and the second discharge port 36, and is located between the two annular plates 34. By opening the movable door 31 opened at the bottom of the fixed shell 30, the material can be removed. This can also effectively achieve continuous sampling.
[0042] During sampling, the temperature in the sampling head 2 and the sampling component 3 can be increased or decreased by manually controlling the controller 50, thereby effectively ensuring that the internal temperature of the sampling head is controlled within a suitable range during sampling, thus ensuring the quality and efficiency of sampling.
