Technical Field
[0001] This utility model relates to the field of asphalt sampling technology, and in particular to an asphalt sampling device. Background Technology
[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It has high viscosity and mostly exists in liquid or semi-solid petroleum form. Asphalt sampling devices are primarily used to inspect the quality of asphalt products, collecting samples for subsequent analysis and testing. They are widely used in asphalt production plants, asphalt transportation, storage, and delivery acceptance.
[0003] Currently, most existing asphalt sampling devices are made of copper. Due to its excellent thermal conductivity, copper can easily cause burns to sampling personnel during high-temperature asphalt sampling. In addition, traditional samplers are often stored upside down in steam ovens, leading to the adhesion of asphalt residue and impurities, which affects the quality of subsequent samples. Utility Model Content
[0004] The technical problem to be solved by this utility model is that in the prior art, asphalt sampling devices are prone to causing burns to the sampling personnel during sampling, and asphalt residue and impurities are prone to adhering to the device after sampling.
[0005] To address the aforementioned technical problems, this utility model provides an asphalt sampling device, comprising a barrel, a sealing assembly, and a hook assembly. The barrel contains a storage cavity for storing asphalt, with a first opening at the bottom and a second opening at the top. The sealing assembly is disposed within the storage cavity, located at the bottom, and slides along the length of the cavity to seal the first opening. The hook assembly includes a first hook and a second hook. The first hook is located at the bottom of the storage cavity, with both ends rotatably connected to the outer wall of the cavity. The second hook is located at the top of the storage cavity, with both ends penetrating the outer wall of the cavity.
[0006] In one embodiment, the sealing assembly includes a fixing member disposed at the bottom end of the storage cavity and connected to the inner wall of the storage cavity. The fixing member has a through hole in its middle part and a clearance hole on the outer periphery of its middle part.
[0007] In one embodiment, the sealing assembly further includes a plug, which is slidably connected to a through hole. One end of the plug is inserted into the storage cavity through the through hole, and the other end is used to seal the first opening.
[0008] In one embodiment, the plug includes a head and a guide portion, both of which are disposed within the storage cavity. The guide portion is inserted into the through hole, and one end of the head is connected to the guide portion, while the other end abuts against the first opening.
[0009] In one embodiment, the outer diameter of the head is larger than the outer diameter of the first opening, and the outer diameter of the head is smaller than the outer diameter of the storage cavity.
[0010] In one embodiment, the first hook is a ring-shaped structure that protrudes outward along the length of the storage cavity. The first hook includes a first hook head and two first extensions. The two first extensions are respectively located at both ends of the first hook head, and one end of each of the two first extensions is fixedly connected to the first hook head.
[0011] In one embodiment, the first hook further includes a locking portion disposed at the end of the first extension away from the first hook head, and the locking portion is disposed on the outer wall of the storage cavity, and the first hook is rotatably connected to the barrel body through the locking portion.
[0012] In one embodiment, the second hook is a ring-shaped protrusion along the length of the storage cavity. The second hook includes a second hook head and two second extensions. The two second extensions are respectively located at both ends of the second hook head, and one end of each of the two second extensions is fixedly connected to the second hook head.
[0013] In one embodiment, the second hook further includes a retaining ring portion, which is disposed at one end of the second extension portion away from the second hook head, and one end of the retaining ring portion passes through the outer wall of the storage cavity, while the other end is fixedly connected to the second extension portion.
[0014] In one embodiment, both the first hook and the second hook are made of high-temperature resistant materials.
[0015] Compared with the prior art, the asphalt sampling device of this utility model has the following advantages: 1) The barrel body, as the main body of the entire device, has a storage cavity inside for storing asphalt samples. The design of the storage cavity takes into account the characteristics of asphalt, especially its viscosity and temperature sensitivity. The first opening at the bottom facilitates the entry of asphalt, while the second opening at the top, when inverted, can drain the asphalt or impurities adhering to the storage cavity, further optimizing the asphalt storage method and reducing asphalt residue and impurity adhesion; 2) The sealing component, located at the bottom of the storage cavity, can slide along the length of the storage cavity, thereby effectively sealing or opening the first opening. This design ensures that the asphalt in the storage cavity will not leak out when sampling is not being performed, maintaining the sealing and safety of the device. At the same time, when sampling is required, the device is inverted, and the weight of the sampler itself moves downward, causing the sealing component to move away from the first opening, thereby opening the first opening and providing space for the asphalt to enter, thus easily enabling the asphalt to enter; 3) The hook assembly, including a first hook and a second hook, are respectively set at the front top of the storage cavity and fixed to the outer wall of the storage cavity in different ways. The two ends of the first hook are rotatably connected to the outer wall of the storage cavity. This design allows the first hook to be adjusted in angle according to time requirements during sampling, facilitating connection with the sampling point or other equipment. The second hook, on the other hand, is directly inserted into the outer wall of the storage cavity. This fixing method is more stable and provides additional support or fixation for the container during sampling. Furthermore, the design of the first and second hooks allows operators to complete asphalt sampling without touching the container. This invention effectively solves the problems in existing asphalt sampling devices, such as the risk of burns to sampling personnel and the presence of asphalt residue and impurities adhering to the device after sampling.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0026] like Figures 1 to 5As shown, the present invention preferably provides an asphalt sampling device, which includes a barrel 1, a sealing component 2, and a hook component 3. The barrel 1 has a storage cavity for storing asphalt inside, with a first opening 11 at the bottom and a second opening 12 at the top. The sealing component 2 is disposed inside the storage cavity and is located at the bottom of the storage cavity. The sealing component 2 slides along the length of the storage cavity to seal the first opening 11. The hook component 3 includes a first hook 31 and a second hook 32. The first hook 31 is disposed at the bottom of the storage cavity and both ends of the first hook 31 are rotatably connected to the outer wall of the storage cavity. The second hook 32 is disposed at the top of the storage cavity and both ends of the second hook 32 are inserted through the outer wall of the storage cavity.
[0027] Based on the aforementioned technical features, the barrel 1 serves as the main body of the entire device. The storage cavity inside the barrel 1 is used to store asphalt samples. The design of the storage cavity takes into account the characteristics of asphalt, particularly its viscosity and temperature sensitivity. The first opening 11 at the bottom facilitates the entry of asphalt, while the second opening 12 at the top, when inverted, can drain asphalt or impurities adhering to the storage cavity, further optimizing the asphalt storage method and reducing asphalt residue and impurity adhesion. The sealing component 2, located at the bottom of the storage cavity, can slide along the length of the cavity, effectively sealing or opening the first opening 11. This design ensures that asphalt in the storage cavity will not leak out when sampling is not being performed, maintaining the device's airtightness and safety. Simultaneously, when sampling is required, the device is inverted, using the sampler's own weight to move downwards, causing the sealing component 2 away from the first opening 11, thereby opening the first opening 11 and providing space for the asphalt to enter, allowing for easy entry. The hook component 3, including a first hook 31 and a second hook 32, is located at the front top of the storage cavity and fixed to the outer wall of the cavity in different ways. The two ends of the first hook 31 are rotatably connected to the outer wall of the storage cavity. This design allows the first hook 31 to be adjusted in angle according to time requirements during sampling, facilitating connection to sampling points or other equipment. The second hook 32, on the other hand, is directly inserted into the outer wall of the storage cavity. This fixing method is more stable and provides additional support or fixation for the container 1 during sampling. Furthermore, the design of the first hook 31 and the second hook 32 allows the operator to complete the asphalt sampling operation without touching the container 1.
[0028] As some embodiments of this utility model, such as Figure 2As shown, the sealing assembly 2 includes a fixing member 21, which is disposed at the bottom end of the storage cavity and connected to the inner wall of the storage cavity. The fixing member 21 has a through hole in its center and a clearance hole on its outer periphery. The main function of the fixing member 21 is to securely install it at the bottom end of the storage cavity, serving as a support structure for the sealing assembly 2. This ensures the stability of the sealing assembly 2 within the storage cavity, preventing it from moving or falling off.
[0029] As some embodiments of this utility model, such as Figure 2 As shown, the sealing assembly 2 also includes a plug 22, which is slidably connected to the through hole. One end of the plug 22 is inserted into the storage cavity through the through hole, and the other end is used to seal the first opening 11. The main function of the plug 22 is to seal the first opening 11 through its slidable connection with the through hole. This slidable connection design allows the operator to flexibly adjust the position of the plug 22 as needed. This adjustability allows the sampling port to lift the plug 22 during sampling, enabling the asphalt to smoothly enter the storage cavity through the clearance hole. After sampling, the plug 22 abuts against the first opening 11 under gravity, preventing asphalt from leaking out.
[0030] As some embodiments of this utility model, such as Figure 2 As shown, the plug 22 includes a head 221 and a guide portion 222, both disposed within the storage cavity. The guide portion 222 is inserted into the through hole. One end of the head 221 is connected to the guide portion 222, and the other end abuts against the first opening 11. Through the arrangement of the head 221 and the guide portion 222, the head 221 is the main sealing part of the plug 22, directly abutting against the first opening 11 to prevent asphalt in the storage cavity from leaking from the first opening 11. The shape and size of the head 221 are typically designed according to the specific dimensions and shape of the first opening 11 to ensure a good sealing effect. The guide portion 222 connects the head 221 and the through hole; it is inserted into the through hole, allowing the plug 22 to slide along the through hole. The length and diameter of the guide portion 222 need to be designed according to the specific dimensions of the through hole to ensure that the plug 22 can be smoothly inserted and slid. The head 221 and the guide portion 222 work together to achieve effective sealing and flexible adjustment of the first opening 11.
[0031] As some embodiments of this utility model, such as Figure 5As shown, the outer diameter of the head 221 is larger than the outer diameter of the first opening 11, while the outer diameter of the head 221 is smaller than the outer diameter of the storage cavity. This design of the outer diameter of the head 221 ensures that the plug 22 can tightly seal the first opening 11 when needed, preventing leakage of substances such as asphalt; simultaneously, it can easily slide along the through-hole when not needed, allowing for flexible switching between opening and closing. This design not only improves the efficiency of the asphalt sampling device but also enhances its safety and reliability.
[0032] As some embodiments of this utility model, such as Figures 3 to 4 As shown, the first hook 31 is a ring-shaped structure that bulges outward along the length of the storage cavity. The first hook 31 includes a first hook head 311 and two first extensions 312, which are respectively located at both ends of the first hook head 311, with one end of each extension fixedly connected to the first hook head 311. The ring-shaped design of the first hook 31 allows the operator to more easily and stably control the balance of the sampler and the transfer of samples. Simultaneously, this design reduces the direct contact area between the first hook 31 and the operator's hands or other objects, making the sample transfer process smoother and preventing sample spillage or contamination. It also reduces the risk of burns and operational errors. As an important component of the sampling device, the first hook 31, with its ring-shaped design bulging outward along the length of the storage cavity and its structure including the first hook head 311 and two first extensions 312, provides strong connection and fixation functions, ensuring the stability and safety of the sampling process.
[0033] As some embodiments of this utility model, such as Figures 3 to 4 As shown, the first hook 31 also includes a locking part 313, which is located at the end of the first extension 312 away from the first hook head 311 and is disposed on the outer wall of the storage cavity. The first hook 31 is rotatably connected to the barrel 1 through the locking part 313. The main function of the locking part 313 is to allow relative rotation between the first hook 31 and the barrel 1, so as to adjust the position and angle of the first hook 31 during sampling or operation, so that the sampler can adapt to different sampling positions.
[0034] As some embodiments of this utility model, such as Figures 3 to 4As shown, the second hook 32 is a ring-shaped protrusion along the length of the storage cavity. The second hook 32 includes a second hook head 321 and two second extensions 322. The two second extensions 322 are located at both ends of the second hook head 321, and one end of each extension 322 is fixedly connected to the second hook head 321. The ring-shaped protrusion of the second hook 32 along the length of the storage cavity also reduces the direct contact area between the first hook 31 and the operator's hand or other objects, making the sample transfer process smoother and preventing sample spillage or contamination. This reduces the risk of burns and operational errors.
[0035] As some embodiments of this utility model, such as Figures 3 to 4 As shown, the second hook 32 also includes a retaining ring 323. The retaining ring 323 is disposed at the end of the second extension 322 away from the second hook head 321, with one end of the retaining ring 323 passing through the outer wall of the storage cavity and the other end fixedly connected to the second extension 322. The main function of the retaining ring 323 is to provide additional fixation and stability. By passing through the outer wall of the storage cavity and being fixedly connected to the second extension 322, the retaining ring 323 ensures that the second hook 32 will not accidentally fall off or loosen during use.
[0036] In some embodiments of this utility model, the first hook 31 and the second hook 32 are both made of high-temperature resistant materials. Asphalt reaches high temperatures during heating and storage. Therefore, the first hook 31 and the second hook 32, which come into contact with it, must be able to withstand these high temperatures without deformation, melting, or performance degradation. High-temperature resistant materials ensure that the hooks maintain stable structure and performance in high-temperature environments. Simultaneously, they prevent operators from directly contacting the high-temperature barrel 1, further ensuring operator safety.
[0037] In summary, this utility model embodiment provides an asphalt sampling device, which has the following advantages compared with the prior art: 1) The barrel 1, as the main body of the entire device, has a storage cavity inside for storing asphalt samples. The design of the storage cavity takes into account the characteristics of asphalt, especially its viscosity and temperature sensitivity. The first opening 11 at the bottom facilitates the entry of asphalt, while the second opening 12 at the top, when inverted, can drain the asphalt or impurities adhering to the storage cavity, further optimizing the asphalt storage method and reducing asphalt residue and impurity adhesion; 2) The sealing component 2 is located at the bottom of the storage cavity and can slide along the length of the storage cavity, thereby effectively sealing or opening the first opening 11. This design ensures that the asphalt in the storage cavity will not leak out when sampling is not being performed, maintaining the sealing and safety of the device. Simultaneously, when sampling is required, the device is inverted, and the sampler's own weight causes it to move downwards, moving the sealing component 2 away from the first opening 11, thereby opening the first opening 11 and providing space for asphalt to enter, thus easily allowing asphalt to enter; 3) Hook assembly 3, which includes a first hook 31 and a second hook 32, respectively set at the front top of the storage cavity and fixed to the outer wall of the storage cavity in different ways. The two ends of the first hook 31 are rotatably connected to the outer wall of the storage cavity. This design allows the first hook 31 to be adjusted in angle according to time requirements during sampling, so as to facilitate connection with the sampling point or other equipment. The second hook 32 is directly inserted into the outer wall of the storage cavity. This fixing method is more stable and can provide additional support or fixation for the barrel 1 during sampling. At the same time, the design of the first hook 31 and the second hook 32 allows the operator to complete the asphalt sampling operation without touching the barrel 1. This utility model effectively solves the problems in the prior art where asphalt sampling devices are prone to causing burns to the sampling personnel during sampling and asphalt residue and impurities are prone to adhering to the device after sampling.
[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
