Description

Technical Field

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

[0002] During concrete production, it is necessary to sample the powder materials to ensure that the quality and performance of the concrete meet the requirements.

[0003] Chinese Patent Publication No. CN219608485U discloses a concrete powder sampling device, including a base plate, a lifting mechanism on the top of the base plate, a lifting plate on the lifting mechanism, a drive cylinder on the top of one end of the lifting plate, and a sampling cylinder fixedly connected to the bottom of one end of the lifting plate. In this invention, the lifting mechanism drives the lifting plate and sampling cylinder downwards, causing the bottom end of the sampling cylinder to insert into the powder in the concrete powder storage cylinder. At this time, a bottom sealing plate blocks the bottom of the sampling cylinder's inner cavity to prevent powder from entering. When the bottom end of the sampling cylinder is inserted to the predetermined sampling height of the powder, an electric push rod drives a spiral conveying rod and the bottom sealing plate to extend from the bottom end of the sampling cylinder. A second motor drives the spiral conveying rod to rotate and sample the powder, achieving the function of sampling powder at a predetermined depth and improving the sampling accuracy of the concrete powder sampling device.

[0004] However, this device has the following drawbacks in use: Although it can sample concrete powder using the combination of a sampling cylinder and a screw conveyor, when used in deeper storage silos, the sampling cylinder and screw conveyor need to be extended, which increases the production cost of the device. Furthermore, the extended sampling cylinder and screw conveyor make it difficult to move the device. To address these drawbacks, we propose a powder sampling device for concrete production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a powder sampling device for concrete production.

[0006] To address the problems existing in the prior art, this utility model adopts the following technical solution: a powder sampling device for concrete production, comprising:

[0007] A guide cylinder, which is installed on an external conveying cylinder, includes a connecting cylinder, and a clearance cylinder and an assembly cylinder respectively fixedly installed on the surface of the connecting cylinder;

[0008] The sampling structure includes a sampling cylinder, a receiving assembly disposed inside the sampling cylinder, a storage assembly disposed on the surface of the sampling cylinder, and an assembly assembly disposed between the sampling cylinder and the assembly cylinder.

[0009] The receiving assembly includes an electric telescopic rod fixedly installed at the left end of the sampling cylinder, a sleeve fixedly installed at the telescopic end of the electric telescopic rod, a guide rod slidably installed on the inner wall of the sleeve, and a sampling frame fixedly installed at the right end of the guide rod. The surface of the guide rod is provided with a rotating component that can drive the sampling frame to rotate.

[0010] The rotating component includes a guide block fixedly mounted on the surface of the guide rod, a handle fixedly mounted on the upper surface of the guide block, and a transverse guide groove and an arc groove respectively opened on the surface of the sampling cylinder, wherein the guide groove and the arc groove are interconnected.

[0011] Preferably, the inner wall of the sleeve is provided with a compression spring, and the other end of the compression spring is fixedly connected to the left end of the guide rod.

[0012] Preferably, both the guide groove and the arc-shaped groove allow the guide block to pass through.

[0013] Preferably, the assembly assembly includes a first flange fixedly installed at the left end of the assembly cylinder and a second flange fixedly installed at the right end of the sampling cylinder.

[0014] Preferably, a sealing plate is fixedly installed at the right end of the sampling frame, and the inner diameters of the assembly cylinder and the clearance cylinder are adapted to the outer diameter of the sealing plate.

[0015] Preferably, the storage assembly includes a funnel fixedly installed on the surface of the sampling cylinder, and the surface of the funnel is threadedly connected to the storage cylinder.

[0016] Preferably, one end of the funnel extends into the interior of the sampling tube and communicates with the interior of the sampling tube.

[0017] Preferably, the assembly cylinder and the clearance cylinder are located on the same central axis.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting up a sampling structure and a guide cylinder, the guide cylinder is installed on the external conveying cylinder. Then, the sampling cylinder and the assembly cylinder are installed as one unit using an assembly structure. When the external conveying cylinder transports powder, the powder will pass through the guide cylinder. Then, the electric telescopic rod in the sampling structure can drive the sampling frame to extend into the connecting cylinder. At this time, the sampling frame can collect the powder that has passed through the connecting cylinder into the sampling frame, thereby sampling the powder. Compared with the existing technology, this device installs the guide cylinder on the external conveying cylinder, so the powder can be sampled at any time as it is conveyed. Moreover, as the powder is conveyed, the amount of powder in the external storage bin can be reduced, so powder at different depths can be sampled. This device is not only simple in structure and low in production cost, but also breaks the existing technology of using the combination of a sampling cylinder and a spiral conveying rod to sample concrete powder. Therefore, there is no need to move the device, which facilitates operation.

[0020] 2. By setting up a receiving component and a rotating part, after the sampling frame has finished sampling, the rotating part can drive the guide frame to rotate 180 degrees, thereby driving the synchronous sampling frame to rotate, forcing the powder in the sampling frame to pour into the funnel and enter the storage cylinder for storage. The operator only needs to unscrew the storage cylinder out of the funnel to take out the sample, which facilitates the retrieval of the sample. Attached Figure Description

Storage cylinder. Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a powder sampling device in concrete production, comprising: a guide cylinder and a sampling structure.

[0030] See Figure 5 The guide cylinder is installed on the external conveying cylinder. It includes a connecting cylinder 1, and a clearance cylinder 2 and an assembly cylinder 3 respectively fixedly installed on the surface of the connecting cylinder 1. The assembly cylinder 3 and the clearance cylinder 2 are located on the same central axis, and both the assembly cylinder 3 and the clearance cylinder 2 are connected to the interior of the connecting cylinder 1.

[0031] See Figure 1-3The sampling structure includes a sampling cylinder 4, a receiving component disposed inside the sampling cylinder 4, a storage component disposed on the surface of the sampling cylinder 4, and an assembly component disposed between the sampling cylinder 4 and the assembly cylinder 3.

[0032] The assembly assembly includes a first flange 14 fixedly installed on the left end of the assembly cylinder 3 and a second flange 15 fixedly installed on the right end of the sampling cylinder 4. After the first flange 14 and the second flange 15 are connected by bolts, the sampling cylinder 4 and the assembly cylinder 3 can be fixed as one unit.

[0033] See Figure 3 The receiving assembly includes an electric telescopic rod 5 fixedly installed on the left end of the sampling cylinder 4, a sleeve 6 fixedly installed on the telescopic end of the electric telescopic rod 5, a guide rod 7 slidably installed on the inner wall of the sleeve 6, and a sampling frame 8 fixedly installed on the right end of the guide rod 7. A sealing plate 16 is fixedly installed on the right end of the sampling frame 8, and the inner diameters of the assembly cylinder 3 and the clearance cylinder 2 are both adapted to the outer diameter of the sealing plate 16.

[0034] After the sampling cylinder 4 and the assembly cylinder 3 are assembled into one unit, the guide cylinder is then installed on the external conveying cylinder. When the external conveying cylinder transports powder, the powder will pass through the guide cylinder. Then, the electric telescopic rod 5 in the sampling structure can drive the sampling frame 8 to extend into the connecting cylinder 1. The sealing plate 16 will enter the avoidance cylinder 2. At this time, the sampling frame 8 can collect the powder that has passed through the connecting cylinder 1 into the sampling frame 8, so that the powder can be sampled. After sampling, the electric telescopic rod 5 is driven to reset, so that the sampling frame 8 can be reset to the sampling cylinder 4. At this time, the sealing plate 16 can seal the assembly cylinder 3 to prevent the powder from entering the sampling cylinder 4.

[0035] See Figure 2-4 The surface of the guide rod 7 is provided with a rotating component that can drive the sampling frame 8 to rotate. The rotating component includes a guide block 9 fixedly installed on the surface of the guide rod 7, a handle 10 fixedly installed on the upper surface of the guide block 9, and a transverse guide groove 11 and an arc groove 12 respectively opened on the surface of the sampling cylinder 4. The guide groove 11 and the arc groove 12 are interconnected, and both the guide groove 11 and the arc groove 12 allow the guide block 9 to pass through. When the electric telescopic rod 5 drives the sampling frame 8 to extend into the connecting cylinder 1, the guide block 9 will slide along the inner wall of the guide groove 11, thereby limiting the running trajectory of the sampling frame 8.

[0036] A compression spring 13 is provided on the inner wall of the sleeve 6. One end of the compression spring 13 overlaps with the inner wall of the sleeve 6, and the other end of the compression spring 13 is fixedly connected to the left end of the guide rod 7. Pulling the handle 10 to the left can drive the guide block 9 to move synchronously. At this time, the compression spring 13 is in a contracted state. Then, the handle 10 can be rotated to drive the guide block 9 into the arc groove 12. Then, rotating the handle 10 can drive the guide block 9 to rotate 180 degrees along the inner wall of the arc groove 12, thereby driving the guide rod 7 and the sampling frame 8 to rotate synchronously.

[0037] See Figure 1-3 The storage assembly includes a funnel 17 fixedly installed on the surface of the sampling cylinder 4. A storage cylinder 18 is threadedly connected to the surface of the funnel 17. One end of the funnel 17 extends into the interior of the sampling cylinder 4 and communicates with the interior of the sampling cylinder 4. When the sampling frame 8 is rotated 180 degrees, the powder in the sampling frame 8 can be forced to pour into the funnel 17 and leak into the storage cylinder 18 for storage. The operator only needs to unscrew the storage cylinder 18 out of the funnel 17 to take out the sample, which facilitates the retrieval of the sample.

[0038] Compared with existing technologies, this device installs the guide cylinder on the external conveying cylinder, so the powder can be sampled at any time as it is conveyed. Furthermore, as the powder is conveyed, the amount of powder in the external storage bin decreases, allowing sampling of powder at different depths. This device is not only simple in structure and low in production cost, but it also breaks away from the existing technology of using a sampling cylinder and a spiral conveying rod to sample concrete powder. Therefore, there is no need to move the device, which facilitates operation.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
