Description

Technical Field

[0001] This utility model relates to the field of cement sampling technology, and in particular to a sampling device for concrete cementitious materials upon arrival at the site. Background Technology

[0002] Concrete, as a primary building material, is mainly composed of cement, aggregate, fine sand, and water, mixed in a specific ratio. Different buildings have different requirements for concrete, primarily differing in the specific gravity of cement and aggregate. Before concrete preparation, the project supervisor must sample and seal the cement for subsequent testing. Samplers are typically used for cement sampling and testing. Existing technologies include manual and automatic samplers. For large-scale sampling, automatic samplers are generally required. However, existing automatic samplers are less flexible and convenient than manual samplers, are typically fixed in place, and are only suitable for a single work scenario: cement delivery pipes, bagged cement, or bulk cement, thus limiting their use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Reference Figure 1-3 A concrete cementitious material sampling device includes a robotic arm 3 and a conveying hose 4. One end of the robotic arm 3 is provided with a clamping seat 2, and a vision sensor 21 is provided on one side of the clamping seat 2. The vision sensor 21 is connected to a processor, which controls the adjustment of the robotic arm 3 to perform automatic sampling. A sampling tube 1 is provided on the clamping seat 2, and one end of the sampling tube 1 is connected to the conveying hose 4. One end of the conveying hose 4 is connected to a sample retention component 5.

[0020] The sampling tube 1 includes a spiral conveying rod 11 and a puncture tube 12. The puncture tube 12 has a sampling port and a puncture cone at one end. The sampling port is close to the puncture cone end. The other end of the puncture tube 12 has a motor 15. The output shaft of the motor 15 is connected to the spiral conveying rod 11. A cavity for accommodating the spiral conveying rod 11 is opened inside the puncture tube 12. The conveying hose 4 communicates with the cavity inside the puncture tube 12. One end of the spiral conveying rod 11 extends to the sampling port for sampling concrete and conveying it through the spiral conveying rod 11.

[0021] The puncture tube 12 is provided with a sliding sleeve 14, and a buffer spring 13 is provided on one side of the sliding sleeve 14. The sliding sleeve 14 is detachably and fixedly connected to the clamping seat 2. The sliding sleeve 14 is slidably connected to the puncture tube 12. The puncture tube 12 is provided with a fixing ring that is fixedly connected to the buffer spring 13. One end of the buffer spring 13 is connected to the sliding sleeve 14. The sliding sleeve 14 and the puncture tube 12 can slide relative to each other. The buffer spring 13 provides buffer protection. As needed, a damping plate can be provided between the sliding sleeve 14 and the puncture tube 12.

[0022] The sample retention assembly 5 includes a collection hopper 51 and a bayonet 52. A detection box 41 is provided on the upper side of the collection hopper 51. The top of the detection box 41 is connected to the conveying hose 4. The conveying hose 4 is connected to the collection hopper 51 through the detection box 41. A microwave solid flow meter 42 is provided on one side of the detection box 41 for detecting the amount of cement powder sampled in the detection box 41. The microwave solid flow meter 42 is used for online flow measurement of solids in metal pipelines. All powders, dust, chips and particles can be repeatedly measured. The measurement range is from kilograms per hour to tons per hour. The microwave solid flow meter 42 is suitable for online measurement in pneumatic conveying or free fall processes.

[0023] A sealing container 7 is detachably installed on the lower side of the bayonet 52 for sealing cement samples. The collection hopper 51 is connected to the sealing container 7. The sealing container 7 is equipped with a seal and label to ensure that the sealing container 7 is clean, dry, moisture-proof, airtight, not easily damaged, and does not affect the performance of cement.

[0024] A guide plate 53 is provided on the inner side of the collection hopper 51. The guide plate 53 is located on the outlet side of the detection box 41. A bellows 55 is connected to the collection hopper 51. The air outlet of the bellows 55 is located on the other side of the guide plate 53. A filter screen 54 is provided on the inner side of the bellows 55. A fan 56 is provided on the upper side of the bellows 55. When the fan 56 is working, it generates a forward or reverse airflow, which is introduced into the collection hopper 51 through the bellows 55 to clean the cement powder in the conveying hose 4 and the sampling tube 1.

[0025] In this embodiment, after the powder tanker vehicle is loaded, the robotic arm 3 works, controlling the sampling tube 1 to approach the sample, the piercing cone is inserted into the cement sample, the motor 15 controls the spiral conveying rod 11 to rotate, and the cement sample is extracted through the sampling port and sent into the conveying hose 4. After passing through the detection box 41, it falls into the collection hopper 51 and is finally sent into the sealing tank 7. During the sampling process, some cement powder remains in the pipeline. The blower 56 draws in or sends in air, generating airflow in the conveying hose 4 and the sampling tube 1 to clean up the residual cement powder. When the blower 56 draws in air, the airflow enters through the sampling port and sucks the cement powder in the conveying hose 4 and the sampling tube 1 into the collection hopper 51. The guide plate 53 interferes with the airflow and, together with the filter screen 54, intercepts the cement powder. Finally, the powder falls into the sealing tank 7.

[0026] When the pipeline is blocked and the air extraction by the blower 56 is restricted, the sealing port 52 is blocked, and the blower 56 sends air into the collection hopper 51 to blow the cement powder out through the sampling port. If necessary, a mesh bag or filter device is installed at the sampling port to intercept the cement powder.

[0027] When the screw conveyor 11 is sampling, the blower 56 is generally not working to avoid interfering with the cement in the powder hopper and affecting the sampling quantity of the sampling tube 1. After the screw conveyor 11 stops sampling, the blower 56 works intermittently to generate pulsating airflow to collect or clean the cement powder, so that the cement can be concentrated in the collection hopper 51 and fall into the storage tank 7.
