Description

Technical Field

[0001] The utility model relates to the technical field of sampling tools, in particular to a portable sampling device. Background Art

[0002] The portable sampling device is a specialized sampling tool. Recycled plastics are processed into granules and packaged in standard ton bags, each containing approximately 0.6 tons of pellets. Finished product quality sampling is required after production. Due to the large packaging volume, inspectors are currently only able to sample the surface. Granulated materials can be affected by factors such as ambient temperature, humidity, and equipment stability. Only surface samples cannot accurately assess quality reliability. Furthermore, quantitative sampling is impossible, and secondary manual interference increases quality control risks and the risk of after-sales complaints.

[0003] Therefore, it is very important to design a sampling tool that can be quantitative and has a wide sampling range. Utility Model Content

[0004] The purpose of the utility model is to provide a portable sampling device to solve the technical problem that the portable sampling device in the prior art can only take surface samples but cannot take quantitative samples.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The utility model provides a portable sampling device, comprising a sampling barrel, a pointed sampling nozzle at one end of the sampling barrel, a transparent observation window on the sampling barrel; scale lines are provided on one side edge of the observation window; and a feed valve is provided between the sampling barrel and the sampling nozzle, which can be opened and closed under material resistance and dead weight.

[0007] The portable sampling device provided by the utility model includes a pointed sampling nozzle located at one end of the sampling barrel, which reduces material stress and makes it easier for the sampler to extend downward, so that samples at different levels can be taken; it includes a transparent observation window arranged on the sampling barrel, which is convenient for observing the position of the internal material; and a scale line is set on the edge of the observation window. The container scale is determined by converting the granulation amount density to achieve quantitative sampling. By arranging a feed valve between the sampling barrel and the sampling nozzle, the valve is automatically opened and closed by the resistance of the material and its own gravity, thereby preventing the sample from falling from the sampler.

[0008] As a further improvement of the present invention, the feed valve includes at least two arc-shaped valve plates evenly arranged along the circumferential direction of the sampling cylinder. All of the valve plates are connected to the sampling cylinder in a limited rotation manner and can be flipped upward to a vertical state or flipped downward to a horizontal state relative to the bottom end of the sampling cylinder; when the valve plates are rotated to a horizontal position, all of the valve plates are pieced together to form the shape of the inner cavity of the sampling cylinder.

[0009] The portable sampling device provided by the utility model is provided with multiple flippable valve plates. When the sample is inserted downward, the valve plates are pushed down by the material to flip open, thereby entering the sampling tube. Then, when the sample is pulled out, the valve plates flip back under the action of gravity, thereby closing the bag mouth of the sampling tube, thereby automatically preventing the sample from falling after sampling.

[0010] As a further improvement of the present invention, the number of the valve plates is three.

[0011] As a further improvement of the present invention, the valve plate is made of aluminum alloy.

[0012] As a further improvement of the present invention, a handle for gripping is further provided on the upper portion of the sampling cylinder.

[0013] As a further improvement of the present invention, the two ends of the scale line are respectively arranged corresponding to the two ends of the observation window.

[0023] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1 As shown, in this embodiment, the utility model provides a sampling portable device, including a sampling barrel 1 with a accommodating cavity, a pointed sampling nozzle 2 is provided at one end of the sampling barrel 1 for quickly entering into different depths of the material, and a discharge port 7 is provided at the other end for discharging the material after sampling; the sampling barrel 1 is also provided with a transparent observation window 3 through which the internal accommodating cavity can be seen; further, the observation window 3 is a long strip window structure, and the length direction extends along the length direction of the sampling barrel 1; considering the volume of the sampling barrel 1 and the sampling amount, the two ends of the observation window 3 are respectively located at the lower and upper parts of the sampling barrel 1, so that the length of the observation window 3 is not less than 1 / 2 of the length of the sampling barrel 1, which is convenient for observing the sampling situation and can be observed whether the sampling barrel 1 samples more or less.

[0026] In this embodiment, the observation window 3 is made of transparent glass.

[0027] In order to facilitate accurate measurement of the sampling amount, in this embodiment, a scale line 4 is provided on one side edge of the observation window 3. Through this structural arrangement, the scale line where the material is located can be read in real time while observing the position of the material in the accommodating chamber, and then the material volume can be calculated based on the position of the scale line, thereby calculating the volume of the material taken and realizing quantitative sampling; in this embodiment, it also includes a feed valve 5 arranged between the sampling cylinder 1 and the sampling nozzle 2, which can open and close under the material resistance and its own weight.

[0028] The portable sampling device provided by the utility model includes a pointed sampling nozzle 2 located at one end of the sampling tube 1, which reduces material stress and makes it easier for the sampler to extend downward, so that samples at different levels can be taken; it includes a transparent observation window 3 arranged on the sampling tube 1, which is convenient for observing the position of the internal material; and a scale line 4 is set on the edge of the observation window 3, and the container scale is determined by the granulation density conversion to achieve quantitative sampling. By arranging a feed valve 5 between the sampling tube 1 and the sampling nozzle 2, the valve is automatically opened and closed by the resistance of the material and its own gravity, thereby preventing the sample from falling from the sampler.

[0029] Example 2:

[0030] In this embodiment, if Figure 1 and Figure 2 As shown, the pointed sampling nozzle 2 is an unsealed inverted cone structure. Figure 1 As shown, the front side of the pointed sampling nozzle 2 is an inverted triangle structure, and both sides are arc-shaped structures; Figure 2 As shown, the side portion of the pointed sampling nozzle 2 is an inverted triangle structure, and the edge portion is an arc structure.

[0031] By setting all sides of the pointed sampling nozzle 2 into an arc structure and the overall shape of an inverted cone, the resistance of the sampling portable device when inserted into the material is reduced, which facilitates better entry into the material. By inserting it into different depths, it is ensured that materials at different depths are extracted. By taking samples at different positions, the reliability of the measurement can be evaluated more scientifically.

[0032] like Figure 1 As shown, in this embodiment, the diameter of the top of the pointed sampling nozzle 2 is 10 cm, the sampling tube 1 is a cylindrical structure, and the diameter is also 10 cm; the height of the pointed sampling nozzle 2 is 7 cm.

[0033] Example 3:

[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, the feed valve 5 includes at least two arc-shaped valve discs 51 evenly arranged along the circumferential direction of the sampling cylinder 1. All the valve discs 51 are connected to the sampling cylinder 1 in a limited rotation manner, and can be flipped upward to a vertical state or flipped downward to a horizontal state relative to the bottom end of the sampling cylinder 1; when the valve disc 51 is rotated to a horizontal position, all the valve discs 51 are pieced together to form the shape of the inner cavity of the sampling cylinder 1, and the bottom inlet of the accommodating cavity of the sampling cylinder 1 is easily closed. When the valve disc 51 is rotated to a vertical position, the bottom inlet of the sampling cylinder 1 is opened, so that the material can enter the accommodating cavity through the inlet to complete the sampling.

[0035] The portable sampling device provided by the present invention is provided with multiple flippable valve plates 51. When the sample is inserted downward, the valve plates 51 are pushed down by the material to flip open, thereby entering the sampling tube. Then, when the sample is pulled out, the valve plates 51 flip back under the action of gravity, thereby closing the bag mouth of the sampling tube, thereby automatically preventing the sample from falling after sampling.

[0036] As an optional embodiment of the present invention, in order to facilitate processing and facilitate the rapid opening and closing of the inlet, the number of valve plates 51 is preferably more than 2, such as 3, 4 or 5 or more; of course, considering that the structure is too complicated when there are too many valve plates 51, in this embodiment, the number of valve plates 51 is three.

[0037] The three valve discs 51 are arranged at an angle of 120 degrees.

[0038] In this embodiment, the valve plate 51 is made of aluminum alloy.

[0039] It should be noted that the sampling tube 1 can be made of the same material as the valve plate 51 , or can be made of a different material.

[0040] The portable sampling device of the utility model adopts a sealed sampling method, thereby avoiding other influencing factors during the sampling process and improving measurement accuracy.

[0041] Example 4:

[0042] In this embodiment, in order to facilitate gripping and operation, as Figure 1 As shown, a handle 6 for gripping is further provided on the upper portion of the sampling tube 1 .

[0043] Specifically, such as Figure 2 As shown, the handle 6 is a round rod structure, symmetrically arranged on two opposite sides of the sampling tube 1, so as to be convenient for holding on both sides.

[0044] The handle 6 has a diameter of 3 cm, which is a specification for easy gripping.

[0045] Example 5:

[0046] In this embodiment, two ends of the scale line 4 are respectively arranged corresponding to two ends of the observation window 3 .

[0047] That is to say, the top of the observation window 3 is aligned with the top edge of the scale line 4, and the bottom of the observation window 3 is aligned with the bottom of the scale line 4. Through this structural setting, the material can be within the visible range.

[0048] In this embodiment, the lowest scale of the scale line 4 is 0.5L, the highest scale is 3.5L, and the accuracy is 0.1L.

[0049] When in use, the material mass can be calculated by reading the scale position of the material in the sampling tube 1, combining the diameter specification of the sampling tube 1 and the material density. Quantitative sampling can be performed according to the sampling requirements to avoid human interference in subsequent weighing.

[0050] When the portable sampling device of the utility model is used, the experimental sampling personnel can use this portable sampling device to achieve different levels of quantitative sampling according to the sampling situation, and better evaluate the quality data of the sample. The specific operation steps are as follows:

[0051] Step 1: Find the granulated material to be sampled, hold the handle 6 tightly with both hands, and align the pointed sampling nozzle 2 with the granulated material;

[0052] Step 2: Press the handle 6 firmly to slowly insert the sampling device into the granulated material. Use the tip of the pointed sampling nozzle 2 to reduce the resistance during the pressing process, making it easier for the sampling device to enter the sample. As the sampling device goes deeper, the resistance will become greater. At the same time, you can rotate the handle 6 left and right appropriately to reduce the resistance and make it easier to enter the sample.

[0053] Step 3: The feed valve 5 is squeezed by the sample, and the valve plate 51 automatically opens and expands to both sides, allowing the sample to enter the sampling tube 1;

[0054] Step 4: Since the observation window 3 is made of transparent glass, the position of the granulated sample in the sampling tube 1 can be observed. Simultaneously observe the container scale line 4 and quantitatively take samples (0.5L-3.5L, accuracy 0.1L).

[0055] Step 5: When the sample reaches the designated scale line 4, the experimenter pulls the handle 6 upwards by hand, rotating it while pulling it out. The rotation amplitude and pulling force should be light. The synchronous feed valve 5 will automatically fall down and close under the gravity of the sample to prevent the sample from leaking out.

[0056] Step 6: The experimenter finds the sample container and places it on the platform. Then, holding the portable sampling device with both hands, they point the discharge port 7 of the portable sampling device toward the transparent sampling bag. Tilt the portable sampling device so that the sample slowly flows out of the discharge port 7 into the transparent sampling bag. Avoid spilling the sample during the pouring process. Finally, wipe the portable sampling device clean, take protective measures, and proceed to the next experimental sampling.
