Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection device technology, and in particular to a sampling device for testing. Background Technology
[0002] Testing and sampling are crucial steps in ensuring project quality and construction safety, necessitating the sampling and testing of various raw materials used in the project. Cement, for example, is a vital raw material. When sampling cement, a certain amount of cement from a bag is typically mixed thoroughly using a sampling device, and then a specific quantity is taken for testing. However, some existing sampling devices involve manually puncturing the cement bags and placing the cement into the sampling equipment. Because cement is powdery, this process easily causes cement to fly everywhere, leading to environmental pollution and leaving workers with a large amount of dust on their noses and bodies.

[0032] Example 1
[0033] like Figures 1-4 As shown, the sampling device used in this utility model for testing includes a sealable box 1. The box 1 includes a door 11. A stirring component is provided inside the box 1. A hook 3 is provided on the top of the box 1. The box 1 also includes a bag-breaking component 4. The bag-breaking component 4 can approach and move away from the bottom of the hook 3. A discharge pipe 12 is provided at the bottom of the box 1. The discharge pipe 12 is equipped with a valve.
[0034] Specifically, in this embodiment, a rectangular box 1 is used. A door 11 is hinged to the front of the box 1. Both the door 11 and the discharge pipe 12 can be closed. The opening direction of the door 11 is not limited; this embodiment uses an outward opening method and can be locked by a bolt. The size of the door 11 is set according to actual needs. An observation window 111 is provided on the door 11 to facilitate confirmation of bag breaking. Bag breaking components 4 are provided on both sides of the box 1 in the width direction. The bag breaking component 4 includes a second mounting plate 41 and several piercing elements 42, such as... Figure 4 As shown, the piercing elements 42 are arranged along the thickness and / or height direction of the box body 1. In this embodiment, the bag-breaking component 4 on one side includes a cuboid second mounting plate 41. The length direction of the second mounting plate 41 is arranged along the thickness direction of the box body 1. A row of piercing elements 42 is provided on the second mounting plate 41. The piercing elements 42 of the bag-breaking components 4 on both sides are staggered in height, as shown. Figure 2 As shown, the second mounting plate 41 is connected to a second telescopic component 43, which is used to move the bag-breaking component 4 closer to and away from the hook 3 in order to break the bagged sample.
[0035] Support legs 13 are provided around the perimeter of the housing 1. The bottom surface of the housing 1 is funnel-shaped, and the bottom of the funnel corresponds to the discharge pipe 12. Figure 2 As shown.
[0036] The top of the housing 1 is provided with a first telescopic component 31, which is connected to a first mounting plate 32. The first mounting plate 32 is provided with a plurality of hooks 3, which are arranged along the width direction of the housing 1, such as... Figure 2 As shown, the hook 3 is positioned facing or away from the bag-breaking component 4. Since bagged samples are typically wider and narrower, this arrangement facilitates positioning the bagged sample with its width facing the puncture component 42, enabling better and more efficient bag breaking. The first mounting plate 32 is equipped with a guide frame 33, and the housing 1 is equipped with guide rods 34 arranged along the lifting direction of the hook 3. Figure 3 As shown, the lifting of the hook 3 enables the guide frame 33 to move longitudinally along the guide rod 34. That is, the lifting of the hook 3 is guided by the guide frame 33 and the guide rod 34 to prevent the bag-breaking component 4 from failing to break the bag effectively. The guide frame 33 and the guide rod 34 are provided on at least both sides of the first mounting plate 32.
[0037] The stirring component includes a drive unit 21, a rotating shaft 22, and blades 23. The drive unit 21 can be a motor that replaces the rotating shaft 22 to rotate, thereby enabling the blades 23 to stir the sample. The specific form of the blades 23 is determined according to actual needs. The height of the stirring component is set according to actual needs to avoid interference from bagged samples.
[0038] In some alternative embodiments, the hook 3 can be extended or retracted by means of existing technologies such as hydraulic cylinders, screws, electric motors, pneumatic cylinders, etc.
[0039] In some alternative embodiments, each hook 3 may be a single hook or a combination of hooks.
[0040] In some alternative embodiments, a bag-breaking component 4 may also be provided on the back of the box 1.
[0041] The sampling device for testing described in this utility model allows bagged samples to be suspended from hooks 3 via an openable door 11. When placing the sample, the bag-breaking component 4 can be kept away to ensure operational safety. The door 11 can be closed to create a sealed environment within the container 1. The movable bag-breaking component 4 is used to break the bagged sample, allowing it to fall into the container 1 where it can be stirred by a mixing component. After being thoroughly mixed, the sample is discharged through the discharge pipe 12. This device effectively completes the mixing and sampling of powdered raw materials, avoids dust dispersion, reduces environmental pollution, lowers the health risks and workload of operators, and features a simple structure and convenient use.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
