Description

Technical Field

[0001] The utility model relates to the technical field of engineering supervision sampling, in particular to an engineering supervision sampling device. Background Art

[0002] Engineering supervision refers to a professional service activity in which a supervision unit with relevant qualifications is entrusted by the construction unit to monitor the construction of the contractor on behalf of Party A in accordance with the state-approved project construction documents, relevant laws and regulations on engineering construction, engineering supervision contracts and other engineering construction contracts. Engineering supervision plays an important role in engineering construction. It can help the construction unit effectively control the quality, progress and cost of the project, improve the efficiency and management level of the project construction, and at the same time, engineering supervision also helps to ensure construction safety and reduce the occurrence of engineering disputes.

[0003] When sampling coarse and fine aggregates, since the aggregates at the construction site are usually stacked according to categories, in order to ensure the accuracy and representativeness of the sampling, it is necessary to uniformly sample the periphery and interior of the stacked aggregates. This can ensure that the sampled aggregates have the same source and properties, thereby avoiding differences caused by different sampling locations.

[0004] Most existing aggregate sampling devices use a hollow metal tube with a cone head. When sampling, it is manually inserted into the pile of materials. When the tube is pulled out, the sampled material will be brought out from the inside of the tube. However, due to the different coarseness of aggregates, it is difficult for sampling personnel to completely insert the hollow metal tube into the pile for coarser aggregates, resulting in inconsistent sampling of peripheral and internal materials during sampling.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 and Figure 3As shown, an engineering supervision sampling device includes a power mechanism 1, which includes a housing 11 and a motor 12, and the motor 12 is fixed in the housing 11; a collecting component 2, which includes a first conveying pipe 21 and a first connecting shaft 22 opposite to its axis. The top of the first conveying pipe 21 is fixedly installed at the axis of the bottom end of the housing 11, and a discharge port 222 is provided on the side surface of the first conveying pipe 21 close to the housing 11. A first conveying leaf 221 is installed on the outer surface of the first connecting shaft 22, and a first conveying blade 221 is provided on the bottom end of the first connecting shaft 22. Threaded hole 223; stepper drill bit 3, the stepper drill bit 3 is threadedly installed in the first threaded hole 223 through the second threaded rod 31, and the motor 12 is set to drive the first connecting shaft 22 to drive the stepper drill bit 3 to drill and excavate the material pile first. As the first connecting shaft 22 rotates, the first conveying blade 221 is driven to convey the material upward, and the conveyed aggregate falls out from the discharge port 222 at the upper end of the first conveying pipe 21. In this way, mechanical power is used instead of traditional manual mining, which is more efficient and labor-saving, and eliminates the problem of manual inability to insert the sampling instrument into the material pile.

[0026] like Figure 3 and Figure 4 As shown, a first connecting thread 224 is provided on the end of the first delivery pipe 21 away from the housing 11; a second connecting thread 231 adapted to the first connecting thread 224 is provided on the outer wall of the top of the second delivery pipe 23, and a third connecting thread 2311 adapted to the second connecting thread 231 is provided on the inner wall of the bottom of the second delivery pipe 23; the second connecting shaft 24 is threadedly connected to the first threaded hole 223 through the first threaded rod 242 at its top, and a second threaded hole 243 adapted to the first threaded rod 242 is provided at the bottom of the second connecting shaft 24, and the second The connecting shaft 24 is threadedly connected to the first threaded hole 223 at the bottom of the first connecting shaft 22 through the first threaded rod 242, and the first threaded rod 242 is also adapted to the second threaded hole 243, thereby realizing the lengthening function, and the required length can be adjusted according to the size of the material pile. At the same time, the second conveying pipe 23 is threadedly connected to the first connecting thread 224 at the bottom of the first conveying pipe 21 through the second connecting thread 231, thereby realizing the sectioning effect and facilitating the removal of the second conveying pipe 23, thereby facilitating the cleaning of the internal second connecting shaft 24 and the second conveying leaf 241.

[0027] like Figure 1 and Figure 6 As shown, the diameter area of ​​the step drill bit 3 near the second threaded rod 31 is larger than the diameter area of ​​the second delivery pipe 23. In this way, when the step drill bit 3 is drilling in front, it ensures that the second delivery pipe 23 and the first delivery pipe 21 behind can have enough space to follow up.

[0028] like Figure 1 and Figure 5As shown, the aggregate assembly 4 includes a discharge nozzle 41 and an aggregate box 42. The discharge nozzle 41 is fixedly installed on the first conveying pipe 21, and the discharge nozzle 41 is located at the lower end of the discharge port 222; the discharge nozzle 41 and the aggregate box 42 are symmetrically provided with connecting holes 43 on the end surfaces close to each other; the two opposite connecting holes 43 are threadedly connected by handle screws 44. By setting up the aggregate box 42, it is convenient to centrally process the sampled aggregates. When the sampling is completed, the aggregate box 42 is removed to facilitate the next operation.

[0029] like Figure 1 and Figure 2 The housing 11 is symmetrically provided with third connecting shafts 111 at both ends along its vertical direction; the third connecting shafts 111 are symmetrically provided with mounting ring grooves 112 in pairs, and the two pairs of mounting ring grooves 112 are hingedly provided with a first handle 113 and a second handle 114, respectively. When the first handle 113 and the second handle 114 are used, since the first handle 113 and the second handle 114 can rotate coaxially, the first handle 113 and the second handle 114 are opened in a direction away from each other when in use, and the user holds and presses down the first handle 113 and the second handle 114 with both hands. Hand 114, insert the entire device into the material pile for sampling, so that the force effect is better. On the contrary, when the device is carried, the first handle 113 and the second handle 114 can be combined for easy picking. By arranging the limiting rods 115 symmetrically installed on both sides of the two third connecting shafts 111 on the casing 11, when the first handle 113 and the second handle 114 are pressed down, the limiting rods 115 play a limiting locking function. By arranging the first handle 113 and the second handle 114 to be provided with an anti-slip cover 116, an anti-slip effect is achieved to prevent the hand from slipping during use.

[0030] The working principle of the present invention is as follows: when in use, the first handle 113 and the second handle 114 are opened respectively, so that the first handle 113 and the second handle 114 are limited by the limiting rod 115, and the motor 12 is started to drive the stepping drill bit 3 under the collecting assembly 2 to perform drilling operations. As the stepping drill bit 3 drills the material pile, the sample is guided upward through the first conveying leaf 221 until it falls from the discharge port 222 into the collection box 42. In order to facilitate sustainable and rapid operation, the collection box 42 is threadedly connected to the discharge nozzle 41 through the handle screw 44, so that the collection box 42 can be directly removed and replaced when the last sampling operation is completed.

[0031] At the same time, this device achieves the effect of adding sections by setting a second connecting shaft 24 and a second conveying pipe 23. The top of the second connecting shaft 24 is equipped with a first threaded hole 223 that is compatible with the bottom end of the first connecting shaft 22, and the bottom end of the second connecting shaft 24 is provided with a second threaded hole 243 that is compatible with the first threaded rod 242. The upper outer wall of the second conveying pipe 23 is provided with a second connecting thread 231 that is compatible with the first connecting thread 224 at the bottom of the first connecting shaft 22, and the bottom inner wall of the second conveying pipe 23 is provided with a third connecting thread 2311 that is compatible with the second connecting thread 231. When facing material piles of different depths, the use requirements can be met by adding sections of the second connecting shaft 24 and the second conveying pipe 23.
