[0001] This utility model relates to the field of concrete sampling technology, specifically a concrete mortar sample sampling device. Background Technology

[0002] A concrete mixing plant is a building material manufacturing equipment consisting of five major systems: a mixing host, a material weighing system, a material conveying system, a material storage system, and a control system, as well as other auxiliary facilities. Its main working principle is to use cement as a binder to mix raw materials such as sand, gravel, lime, and cinders, and finally produce concrete, which is used as a wall material in construction. Before the concrete is used, it needs to be tested to prevent poor concrete quality from causing building collapse. Therefore, a concrete mortar sampling device is needed.

[0003] After each sampling of concrete mortar, the inside of the sampling device usually needs to be cleaned; otherwise, the concrete mortar will solidify inside the sampling device, affecting its next use. However, current sampling devices are usually integrated, making it difficult to clean the sampling device after each use, and the inside of the sampling device is difficult to clean thoroughly, affecting its next use.

[0004] Therefore, we propose a concrete mortar sampling device to address the problems mentioned above. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0020] Embodiments of this utility model: This utility model provides a concrete mortar sample taking device, including a sampling cylinder 1, the bottom of which is open for taking concrete mortar samples; the upper part of the sampling cylinder 1 has a sampling port 2, which allows the sampled mortar concrete to be discharged. A rotating rod 3 is located at the center of the sampling cylinder 1. It should be noted that the rotating rod 3 can not only rotate inside the sampling cylinder 1, but can also be disassembled from the sampling cylinder 1 to facilitate subsequent cleaning. A spiral blade 4 is fixed on the rotating rod 3 and is located inside the sampling cylinder 1. As the rotating rod 3 drives the spiral blade 4 to rotate, the concrete mortar can be conveyed upward with the spiral blade 4. It should be noted that the outer wall of the spiral blade 4 is in contact with the inner circumferential wall of the sampling cylinder 1 to prevent the mortar from falling during the conveying process. A spiral sampling channel 5 is formed between the spiral blade 4 and the inner circumferential wall of the sampling cylinder 1. Through the sampling channel 5, the concrete mortar can be conveyed upward with the sampling channel 5 and taken out from the sampling port 2, thereby completing the sampling work. A drainage pipe 8 is detachably installed at sampling port 2. The drainage pipe 8 allows concrete mortar to be drained to a designated location. In detail, one end of the drainage pipe 8 is fixed with a threaded connector 801, which is threadedly connected to the sampling port 2. The threaded connector 801 allows for quick disassembly of the drainage pipe 8, providing convenience for staff. The top of the rotating rod 3 is detachably mounted with a rotating component 6 through the sampling cylinder 1, and the rotating component 6 is located at the top of the sampling cylinder 1. The rotating component 6 facilitates the rotation of the rotating rod 3, thus providing convenience for the staff. In detail: The rotating assembly 6 includes a mounting part 601, and a plurality of connecting plates 602 are fixed at equal intervals on the circumferential surface of the mounting part 601. One end of the plurality of connecting plates 602 is fixed to the same rotating ring 603, and a handle 604 is fixed to the top of the rotating ring 603. A rotating sleeve 605 is rotatably mounted on the handle 604. When the operator holds the rotating sleeve 605 and rotates the handle 604, the rotating sleeve 605 can rotate on the handle 604. The handle 604 can drive the rotating ring 603 to rotate, so that the rotating ring 603 drives the same mounting part 601 to rotate through the plurality of connecting plates 602, so that the mounting part 601 can drive the rotating rod 3 to rotate. A stepped hole 606 is provided at the center of the mounting component 601, and a first threaded groove 301 is fixed at the top of the rotating rod 3. When the stepped hole 606 and the first threaded groove 301 are aligned, the first fixing bolt (usually referring to an internal hex bolt) 607 passes through the stepped hole 606 and is threaded into the inside of the first threaded groove 301, thereby fastening the mounting component 601. Conversely, when the first fixing bolt 607 is removed from the inside of the first threaded groove 301, the rotating rod 3 can fall out of the sampling cylinder 1 due to its own gravity, making disassembly convenient and facilitating subsequent cleaning work.

[0021] It should be noted that: a locking hole 608 is provided at the center of the bottom of the mounting part 601, and the top of the rotating rod 3 is conveniently mounted inside the locking hole 608; it should be noted that: several locking parts 609 are evenly fixed on the inner circumferential wall of the locking hole 608, and a certain gap is left between two adjacent locking parts 609; several locking grooves 302 are evenly provided on the top of the rotating rod 3 along the circumferential direction. When the rotating rod 3 is inserted into the locking hole 608, several locking parts 609 are also inserted into the corresponding locking grooves 302, thereby playing a locking role and preventing the rotating rod 3 and the rotating assembly 6 from rotating in opposite directions; The bottom of the mounting component 601 is equipped with a sliding component 610, and the top of the sampling cylinder 1 is fixed with a support base 7. The support base 7 is coaxially arranged with the rotating rod 3. The top of the support base 7 is provided with a "ring"-shaped groove 701, and the sliding component 610 is slidably installed inside the groove 701. Through the cooperation between the sliding component 610 and the groove 701, the rotating component 6 can rotate smoothly, reducing friction and making it less prone to jamming.

[0022] In detail: the sliding component 610 includes a number of placement grooves 6101 equidistantly opened along the circumferential direction at the bottom of the mounting component 601, and the placement grooves 6101 are arranged in a "hemispherical" shape. Each placement groove 6101 has a ball bearing 6102 rolled inside it. It should be noted that one-third of the ball bearing 6102 is rolled inside the sliding groove 701. During the rotation of the rotating component 6, the friction is small and it is not easy to jam.

[0023] An annular baffle 6103 is provided between the mounting component 601 and the support base 7. It should be noted that: several limiting grooves 6104 are equally spaced along the circumferential direction on the annular baffle 6103, and the diameter of the limiting grooves 6104 is smaller than the diameter of the ball 6102. The limiting grooves 6104 limit the ball 6102 and prevent the ball 6102 from derailing during use. The annular baffle 6103 is also provided with a number of mounting holes 6105 at equal intervals along the circumference, and the mounting holes 6105 and the limiting grooves 6104 are staggered. The bottom end of the mounting part 601 is provided with a number of second threaded grooves 6106 at equal intervals along the circumference. Each second fixing bolt 6107 passes through the mounting hole 6105 and is threadedly connected to the second threaded groove 6106, thereby fastening the annular baffle 6103 and preventing the annular baffle 6103 from falling off during use.

[0024] When sampling concrete mortar: First, insert the bottom end of the sampling cylinder 1 into the concrete mortar, and then rotate the rotating component 6. During the rotation of the rotating component 6 and the rotating rod 3, several balls 6102 can also be driven to roll inside the slide groove 701. This allows the rotating rod 3 to drive the spiral blade 4 to rotate inside the sampling cylinder 1. During the rotation of the spiral blade 4, the concrete mortar can be transported, so that the concrete mortar can be transported along the sampling channel 5 to the sampling port 2. The sample taken out is transported to the designated position through the sampling port 2 and the drainage pipe 8 in sequence.

[0025] When cleaning is required after sampling the concrete mortar: use a wrench to loosen the first fixing bolt 607. If the bottom end of the first fixing bolt 607 is removed from the inside of the first threaded groove 301, the rotating rod 3 will fall downwards due to its own gravity, so that the rotating rod 3 can drive the spiral blade 4 to fall out of the inside of the sampling cylinder 1, so that the spiral blade 4 is separated from the sampling cylinder 1. The sampling cylinder 1 and the spiral blade 4 can be cleaned separately, which is convenient and provides convenience for the staff.
