Description

Technical Field

[0001] The utility model relates to the technical field of concrete aggregate sampling, and more specifically to a concrete raw material silo sampling device. Background Art

[0002] The raw materials for making concrete mainly include sand, cement and aggregate. When making concrete, water, aggregate, cement and sand are mixed together in a certain proportion and stirred in a mixer to make cement concrete. Aggregates play a very important role in concrete, so the quality of the produced concrete is closely related to aggregates. Aggregates not only play a filling role in concrete, but also serve as the skeleton of concrete to improve the strength of concrete. Nowadays, some civil engineering construction sites will sample and test aggregates to ensure the quality of aggregates used in making concrete.

[0003] At present, when sampling and testing aggregates, some places still use manual sampling from the aggregate pile, which wastes manpower when sampling. Construction sites with better conditions use some sampling devices to sample on site, which can reduce the workload of workers to a certain extent. However, many existing sampling devices have relatively simple structures and cumbersome operating steps, and cannot sample and test aggregates that are being used in production. Sampling and testing requires a lot of time, which affects production progress.

[0004] Therefore, it is difficult for traditional aggregate sampling devices to sample aggregates used in production and the sampling efficiency is low. Utility Model Content

[0005] The utility model provides a concrete raw material storage bin sampling device, which solves the problems of low efficiency and poor sealing performance of the existing concrete raw material storage bin sampling device, which is easy to cause environmental pollution.

[0014] The utility model discloses a concrete raw material silo sampling device, which can effectively collect the powder dropped during the sampling process of the sampling rod by installing an adapter box on the silo, and can quickly clean the powder in the adapter box by disassembling the adapter box.

[0026] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model.

[0027] See also Figure 1 , and combined with Figure 2 As shown, a concrete raw material silo sampling device of the present invention is used to be installed on a silo 3 and is used to sample and test the concrete raw materials in the silo 3.

[0028] Specifically, the concrete raw material silo sampling device of the utility model comprises an adapter box 1 and a sampler 2. The adapter box 1 is detachably and sealedly mounted on the silo 3 to isolate and prevent the problem of sample leakage during the sampling process.

[0029] Specifically, the sampler 2 includes a through tube 21, a sampling rod 22 and a driving cylinder 23. The driving cylinder 23 is installed on the through tube 21. The sampling rod 22 is inserted into the through tube 21. The through tube 21 is inserted into the adapter box 1 and extends into the silo 3. The end of the sampling rod 22 is connected to an external rotating head 24. The sampling rod 22 is provided with an adapter 25. The telescopic head of the driving cylinder 23 is connected to the sampling rod 22 via the adapter 25.

[0030] When sampling is not being done, the telescopic head of the driving cylinder 23 is in an extended state. At this time, the sampling end of the sampling rod 22 is retracted in the through tube 21 to keep the sampling end of the sampling rod 22 in a sealed state to avoid contamination, which may lead to the problem of contamination of the raw materials in the silo 3 during the sampling process. When sampling, the telescopic head of the driving cylinder 23 can be retracted to drive the sampling rod 22 to move into the silo 3. When the end of the sampling rod 22 is inserted into the silo 3, the sample is obtained through the sampling end of the sampling rod 22. At the same time, the driving cylinder 23 is extended to allow the sampling rod 22 to move in the through tube 21 away from the silo 3. When it moves to a certain position, the sampling rod 22 is driven to rotate by the rotating head 24, so that the material on the sampling rod 22 is poured downward, thereby achieving the purpose of automatic sampling.

[0031] During the sampling process, the design of the adapter box 1 allows for quick disassembly of the external structure, making it easy to modify and disassemble. At the same time, during the movement of the sampling rod 22, it is unavoidable that external vibrations may cause the material on the sampling rod 22 to fall. The structural design of the adapter box 1 allows for effective collection of the powder that falls during the sampling process of the sampling rod 22. By disassembling the adapter box 1, the powder in the adapter box 1 can be quickly cleaned.

[0032] The utility model provides a concrete raw material silo sampling device. By installing an adapter box 1 on the silo 3, the powder dropped during the sampling process of the sampling rod 22 can be effectively collected. By disassembling the adapter box 1, the powder in the adapter box 1 can be quickly cleaned. At the same time, due to the structural arrangement of the adapter box 1 and the through-tube 21, the sampling process is sealed throughout, effectively reducing the pollution of dust to the outside world. At the same time, the driving cylinder 23 can drive the sampling rod 22 to move relative to the silo 3, so as to realize its automatic sampling. At the same time, combined with the structure of the rotating head 24, the automatic unloading of the sample on the sampling rod 22 can be completed through the rotating head 24. It is convenient and quick to use and has a compact structure.

[0033] Specifically, the adapter sleeve 28 of the utility model is sleeved on the sampling rod 22 , the adapter 25 is arranged on the adapter sleeve 28 , and the telescopic head of the driving cylinder 23 is hinged to the adapter 25 .

[0034] like Figure 2 As shown, the adapter box 1 of the present invention is provided with a receiving cavity 11 , and a through hole 12 is provided at the end of the adapter box 1 close to the silo 3 to facilitate the insertion or withdrawal of the sampling rod 22 .

[0035] Preferably, a sealing gasket is provided between the adapter box 1 and the silo 3 of the utility model, and a discharge port 26 is provided on the outer edge surface of the end of the through-tube 21 away from the silo 3, the discharge port 26 is externally connected to a conical sampling outlet 27, and an electromagnetic control valve 41 is provided at the end of the sampling outlet 27. The quantitative delivery of the sample can be achieved through the electromagnetic control valve 41 at the discharge port 26 and the sampling outlet 27, which is convenient to use and has high automation intensity.

[0036] The end of the through-tube 21 of the present invention facing away from the silo 3 is provided with a sealing plug, the sampling rod 22 penetrates the sealing plug, and the end of the sampling rod 22 is provided with a carrying bucket 4 to facilitate carrying samples and materials and avoid the loss of materials. Preferably, the carrying bucket 4 is arc-shaped.

[0037] The utility model provides a concrete raw material silo sampling device. By installing an adapter box 1 on the silo 3, the powder dropped during the sampling process of the sampling rod 22 can be effectively collected. By disassembling the adapter box 1, the powder in the adapter box 1 can be quickly cleaned. At the same time, due to the structural arrangement of the adapter box 1 and the through-tube 21, the sampling process is sealed throughout, effectively reducing the pollution of dust to the outside world. At the same time, the driving cylinder 23 can drive the sampling rod 22 to move relative to the silo 3, so as to realize its automatic sampling. At the same time, combined with the structure of the rotating head 24, the automatic unloading of the sample on the sampling rod 22 can be completed through the rotating head 24. It is convenient and quick to use and has a compact structure.

[0038] Finally, the method of this application is only a preferred implementation scheme and is not intended to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
