Description

Technical Field

[0001] This utility model relates to the technical field of asphalt sampling equipment, specifically an asphalt sampler for testing modified asphalt. Background Technology

[0002] Modified asphalt requires sampling and testing during storage at the production plant or upon delivery and acceptance. Modified asphalt comes in various forms, including viscous, liquid, and emulsion. Therefore, asphalt samplers have been developed.

[0003] Existing asphalt samplers require a lot of effort to pull up, which affects the sampling work of the staff. Therefore, some people have thought of setting the pull rod of the lifting piston as a screw, and rotating the screw to drive the piston up and down. For example, Chinese utility model patent with announcement number CN215574008U discloses an asphalt sampler for modified asphalt testing.

[0004] However, in actual use, it is found that the above-mentioned modified asphalt sampler is difficult to sample modified asphalt at different depths. When sampling, the top bucket needs to be directly inserted into the asphalt. However, because the top bucket has an opening for sucking up the asphalt, the asphalt above will directly enter through the opening when it is inserted. Even if the sampler is inserted into the asphalt at a relatively deep depth, a large amount of upper asphalt will still enter the sampling bucket when sucking up, which is very inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide an asphalt sampler for testing modified asphalt, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an asphalt sampler for testing modified asphalt, comprising a sampling cylinder and a piston disposed inside the sampling cylinder.

[0007] The sampling cylinder has a connecting sleeve at the bottom, and a suction head is located below the connecting sleeve. A suction port is opened on the side of the suction head, and several plugs that mate with the suction port are located on the side of the piston. These plugs are inserted into the suction port. By inserting the plugs into the suction port, the upper layer of asphalt can be effectively prevented from directly entering the sampling cylinder from the suction port when the modified asphalt is inserted.

[0008] A screw and a positioning rod are fixed above the piston, both passing through the top of the sampling cylinder. A threaded sleeve is threadedly connected to the outer side of the screw, and the threaded sleeve is rotatably connected to the sampling cylinder. The threaded sleeve is rotatably connected to the sampling cylinder via an annular rotating shaft. By rotating the threaded sleeve, the threaded sleeve drives the screw to move up and down, which in turn drives the piston to move up and down, thereby achieving the function of sucking up asphalt.

[0009] As a preferred embodiment of this utility model, the sampling tube is provided with an observation window on the front and a scale on the side of the observation window, which allows staff to easily view the inside of the sampling tube.

[0010] As a preferred embodiment of this invention, a handle is fixed to the side of the sampling cylinder near the top, and the handle is mainly provided to facilitate the staff to pick up the device.

[0011] As a preferred embodiment of this invention, the sampling cylinder is fixed with an installation ring near the bottom, and the connecting sleeve is threaded onto the installation ring, thereby enabling the suction head to be detachable.

[0012] As a preferred embodiment of this invention, a protective cover is provided on the outside of the suction head. The protective cover is used to protect the suction head and can be removed during use, as the protective cover is secured to the suction head.

[0013] As a preferred embodiment of this utility model, several auxiliary blocks are fixed on the outer side of the threaded sleeve. The auxiliary blocks are mainly designed to facilitate the rotation of the threaded sleeve by the operator.

[0014] As a preferred embodiment of this invention, the suction head is conical, which facilitates insertion into asphalt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a plug on the piston and a suction port on the side of the conical suction head that mates with the plug. When not drawing asphalt, the plug is inserted into the suction port to prevent asphalt from directly entering the sampling cylinder. After the sampling cylinder is inserted to a certain depth, the threaded sleeve is rotated, and the screw drives the piston to draw up the asphalt. This allows the sampling cylinder to draw up asphalt at different depths, thus improving the practicality of the device. Attached Figure Description

[0025] Please see Figure 1-4 This utility model provides a technical solution: an asphalt sampler for testing modified asphalt, including a sampling cylinder 100 and a piston 300 disposed inside the sampling cylinder 100.

[0026] The sampling cylinder 100 has a connecting sleeve 200 at its bottom, and a suction head 201 is located below the connecting sleeve 200. The suction head 201 has a suction port 2011 on its side, and the piston 300 has several plugs 3001 on its side that mate with the suction port 2011. The plugs 3001 are inserted into the suction port 2011. By inserting the plugs into the suction port 2011, it is effectively prevented that the upper layer of asphalt directly enters the sampling cylinder 100 from the suction port 2011 when the modified asphalt is inserted.

[0027] A screw 301 and a positioning rod 302 are fixed above the piston 300. Both the screw 301 and the positioning rod 302 pass through the top of the sampling cylinder 100. A threaded sleeve 400 is threadedly connected to the outer side of the screw 301, and the threaded sleeve 400 is rotatably connected to the sampling cylinder 100. The threaded sleeve 400 is rotatably connected to the sampling cylinder 100 via an annular rotating shaft. By rotating the threaded sleeve 400, the threaded sleeve 400 drives the screw 301 to move up and down, which in turn drives the piston 301 to move up and down, thereby achieving the function of sucking up asphalt.

[0028] Furthermore, the sampling tube 100 is provided with an observation window 101 on the front and a scale on the side of the observation window 101. The observation window 101 allows staff to easily view the inside of the sampling tube 100.

[0029] Furthermore, a handle 102 is fixed on the side of the sampling cylinder 100 near the top. The handle 102 is mainly designed to make it easier for staff to pick up the device.

[0030] Furthermore, a mounting ring 103 is fixed near the bottom of the sampling cylinder 100, and the connecting sleeve 200 is threaded onto the mounting ring 103, thereby enabling the suction head 201 to be detachable.

[0031] Furthermore, a protective cover 500 is provided on the outside of the suction head 201. The protective cover 500 is used to protect the suction head 201. It can be removed during use, as the protective cover 500 is attached to the suction head 201.

[0032] Furthermore, several auxiliary blocks 401 are fixed on the outside of the threaded sleeve 400. The auxiliary blocks 401 are mainly designed to facilitate the rotation of the threaded sleeve 400 by the operator.

[0033] Furthermore, the suction head 201 is conical, which is mainly to facilitate insertion into the asphalt.

[0034] In summary, when using this device, simply remove the protective cover 500 from the suction head 201, and then insert the suction head 201 into the modified asphalt. Since the blocking block 3001 on the piston 300 is inserted into the suction port 2011, it can effectively prevent the upper layer of asphalt from directly entering the sampling cylinder 100. After inserting to a certain depth, use the auxiliary block 401 to rotate the threaded sleeve 400, so that the threaded sleeve 400 drives the screw 301 to move upward, and use the screw 301 to drive the piston 300 to move upward, so that the asphalt enters the sampling cylinder 100 from the suction port 2011, thereby realizing the sampling of modified asphalt at different depths.

[0035] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
