Description

Technical Field

[0001] This utility model relates to the technical field of concrete sampling equipment, and in particular to a concrete sampling device. Background Technology

[0002] Concrete is the most widely used man-made composite material in construction engineering. It is mainly composed of cement, sand, stone (aggregate), and water in a certain proportion, which are mixed, poured, and cured to harden. In some cases, admixtures (such as water-reducing agents and antifreeze agents) are added to optimize performance. It is a core material for bridges, buildings, roads, water conservancy projects, etc. Its core advantages are high plasticity, high strength, and good durability: it can be poured into any shape before hardening, and after hardening, it can withstand greater pressure and loads, adapting to different engineering needs (such as C30 concrete for ordinary buildings, and C60 and above high-strength concrete for long-span bridges). According to function, it can be divided into structural concrete, waterproof concrete, and thermal insulation concrete, etc., and according to aggregate type, it can be divided into crushed stone concrete and pebble concrete. Its raw materials are readily available and its cost is controllable. It can also be combined with steel bars to form reinforced concrete, which greatly improves tensile strength. It remains an indispensable basic material in modern engineering construction. When using concrete, it is necessary to conduct sampling tests during use. Generally, when sampling, a shovel or spoon is used to take samples, which results in a small number of samples and makes it difficult to conduct multiple tests. Therefore, a concrete sampling device is used to quickly sample the concrete in the concrete pouring pipe, which makes it convenient to collect the sample amount at one time.

[0003] However, the existing equipment has the following shortcomings: when sampling concrete, the existing equipment makes it difficult to accurately feed the concrete into the concrete pipes due to the different heights of the concrete pipes, resulting in concrete scattering into the box and causing pollution to the equipment.

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

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in smoothly collecting concrete samples from different heights, which causes concrete to easily splash around the equipment and pollute the environment. Therefore, a concrete sampling device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a concrete sampling device, comprising a box, a rotating wheel, a handle, a support, and a feeding device. The handle is fixedly connected to the side of the box, the support is fixedly connected to the lower end of the box, the rotating wheel is installed on the side of the box, and the feeding device is installed on the upper end of the box. The feeding device includes a feeding hopper and a rotating column. The feeding hopper is installed on the upper end of the box, and the rotating column is fixedly connected to the side of the feeding hopper. The rotating column is rotatably connected inside the box. A groove is provided at the end of the rotating column away from the feeding hopper, and a pull rod is slidably connected inside the groove. A turntable is fixedly connected at the end of the pull rod away from the rotating column, and a positioning hole is provided on the surface of the turntable.

[0007] Furthermore, a positioning rod is fixedly connected to the surface of the housing. The positioning rod is inserted into the positioning hole. By setting the positioning rod, the turntable can be limited, reducing the difficulty of limiting the turntable during use.

[0008] Furthermore, a handle is fixedly connected to the end of the turntable away from the pull rod, and the handle facilitates the movement of the turntable.

[0009] Furthermore, a first spring is fixedly connected to the end of the pull rod away from the turntable, and the end of the first spring away from the pull rod is fixedly connected inside the pull groove. The first spring is provided to facilitate the application of a restoring force to the pull rod.

[0010] Furthermore, an auxiliary component is fixedly provided on the surface of the box. The auxiliary component includes a mounting plate and a limiting block. The limiting block is fixedly connected to the surface of the box, and the mounting plate is fixedly connected to the surface of the box. A sliding groove is provided on the side of the limiting block, and a blocking plate is slidably connected inside the sliding groove. By setting the blocking plate, the discharge end of the box can be blocked, reducing the difficulty of blocking the discharge end of the box during use.

[0011] Furthermore, the lower end of the baffle plate abuts against the surface of the box, and a connecting block is fixedly connected to the upper surface of the baffle plate.

[0012] Furthermore, an elastic plate is fixedly connected to the upper end of the connecting block, and the elastic plate can limit the position of the blocking plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a feeding device, the concrete is effectively guided, which plays a role in guiding the material. This reduces the problem that existing equipment cannot accurately feed concrete into the concrete pipe due to the different heights of the concrete pipe when sampling concrete, which causes concrete to scatter into the box and contaminate the equipment. This feeding device realizes the guidance of concrete and improves the stable sampling of the equipment.

[0014] 2. In this utility model, by setting an auxiliary component, the baffle plate is effectively limited, which plays a role in stabilizing the baffle plate. This reduces the problem of existing equipment arbitrarily tilting the equipment or using a shovel to remove concrete when handling concrete. Placing the concrete on the testing platform with a shovel or tilting will cause pollution to the testing platform and affect the equipment's concrete testing. This auxiliary component enables convenient material loading into the box and improves the practicality of the equipment. Attached Figure Description

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a concrete sampling device, including a box 1, a rotating wheel 2, a handle 3, a bracket 4 and a feeding device 5. The handle 3 is fixedly connected to the side of the box 1, the bracket 4 is fixedly connected to the lower end of the box 1, and the rotating wheel 2 is installed on the side of the box 1.

[0020] The container 1 is the core container for concrete sampling. It is made of wear-resistant and impact-resistant metal with a smooth, easy-to-clean inner wall. It can completely hold and store concrete samples, avoiding sample residue or contamination. The casters 2 are installed at the bottom of the container 1 and feature a universal wheel design with a self-locking function, making it easy for users to move the device and fixing its position to prevent slippage during sampling. The handle 3 is made of non-slip rubber, providing a comfortable grip and a leverage point for moving the device, reducing the burden on users when carrying it. The support 4 provides auxiliary support for the container 1 and works with the casters 2 to keep the container 1 level, ensuring that concrete falls evenly into the container during sampling. The feeding device 5 can adjust the feeding angle to adapt to concrete pouring pipes of different heights, preventing concrete from scattering and improving sampling accuracy.

[0021] The specific setup and function of its feeding device 5 and auxiliary components 6 will be explained below.

[0022] In this implementation scheme: the feeding device 5 is installed at the upper end of the box body 1. The feeding device 5 includes a feeding hopper 51 and a rotating column 52. The feeding hopper adopts a funnel-shaped structure with a larger upper opening and a smaller lower opening, which can expand the receiving area and guide the concrete to fall accurately into the box body 1, avoiding spillage. The rotating column 52 is the rotating shaft of the feeding hopper 51 and is rotatably connected to the box body 1, so that the feeding hopper 51 can flexibly adjust its angle to adapt to concrete pouring pipes of different heights and angles. The feeding hopper 51 is installed at the upper end of the box body 1, and the rotating column 52 is fixedly connected to the side of the feeding hopper 51. The rotating column 52 is rotatably connected inside the box body 1. A groove 53 is opened at the end of the rotating column 52 away from the feeding hopper 51. A pull rod 54 is slidably connected inside the groove 53. A turntable 56 is fixedly connected at the end of the pull rod 54 away from the rotating column 52. A positioning hole 57 is opened on the surface of the turntable 56.

[0023] Specifically, a positioning rod 59 is fixedly connected to the surface of the housing 1, and the positioning rod 59 is inserted into the positioning hole 57.

[0024] In this embodiment, by setting the positioning rod 59, the turntable 56 can be limited, reducing the difficulty of limiting the turntable 56 during use.

[0025] Specifically, a handle 58 is fixedly connected to the end of the turntable 56 away from the pull rod 54, and the handle 58 is provided to facilitate the movement of the turntable 56.

[0026] Specifically, a first spring 55 is fixedly connected to the end of the pull rod 54 away from the turntable 56. The end of the first spring 55 away from the pull rod 54 is fixedly connected to the inside of the pull groove 53. The first spring 55 is provided to facilitate the application of a restoring force to the pull rod 54.

[0027] In this implementation scheme: An auxiliary component 6 is fixedly installed on the surface of the box 1. The auxiliary component 6 includes a mounting plate 61 and a limiting block 62. The mounting plate 61 provides limiting support for the elastic plate 65 to ensure that the blocking plate 63 is stable after locking. The limiting block 62 provides sliding guidance for the blocking plate 63 to ensure that the blocking plate 63 moves in a straight line and accurately blocks or opens the discharge end of the box 1. The limiting block 62 is fixedly connected to the surface of the box 1, and the mounting plate 61 is fixedly connected to the surface of the box 1. A sliding groove 66 is opened on the side of the limiting block 62. The blocking plate 63 is slidably connected inside the sliding groove 66. The blocking plate 63 is made of wear-resistant metal material with a smooth surface and can completely block the discharge end of the box 1.

[0028] In this embodiment: by setting the baffle plate 63, the discharge end of the box 1 can be blocked, reducing the difficulty of blocking the discharge end of the box 1 when the equipment is in use.

[0029] Specifically, the lower end of the baffle plate 63 abuts against the surface of the housing 1, and a connecting block 64 is fixedly connected to the upper surface of the baffle plate 63.

[0030] Specifically, an elastic plate 65 is fixedly connected to the upper end of the connecting block 64. The elastic plate 65 can limit the position of the blocking plate 63.

[0031] Working Principle: When using the equipment, the user pushes the housing 1 to the discharge end of the concrete inlet pipe and then starts the concrete inlet to discharge the concrete into the housing 1 for rapid sampling. When receiving the concrete in the discharge pipe, the user pulls the handle 58 to move the turntable 56. The turntable 56 then drives the pull rod 54 to stretch the first spring 55, generating elastic force. The turntable 56 then disengages from the surface of the positioning rod 59, and the feed hopper 51 rotates, causing the rotating column 52 to rotate inside the housing 1 to adjust the feeding angle. By setting up the feeding device 5, the concrete is effectively guided, which reduces the difficulty of accurately feeding concrete into the concrete pipe due to the different heights of the concrete pipe, resulting in concrete scattering into the housing 1 and causing pollution to the equipment. This feeding device 5 guides the concrete and improves the stability of the equipment sampling.

[0032] The user moves the equipment to the testing area and then pulls the connecting block 64 to move the baffle plate 63 in the sliding groove 66 inside the limiting block 62. The baffle plate 63 then disengages from the discharge end, and the elastic plate 65 is then moved to contact the surface of the mounting plate 61, limiting the baffle plate 63. By setting the auxiliary component 6, the baffle plate 63 is effectively limited, which stabilizes the baffle plate 63. This reduces the problem of the existing equipment arbitrarily tilting the equipment or using a shovel to remove the concrete when handling concrete. Placing the equipment on the testing platform with a shovel or tilting the equipment will contaminate the testing platform and affect the equipment's concrete testing. This auxiliary component 6 enables convenient material discharge from the box 1 and improves the practicality of the equipment.

Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
