Description

Technical Field

[0001] This utility model relates to a sampling device for testing and inspecting finished products in a sand and gravel plant. Background Technology

[0002] In the production and quality control of sand and gravel aggregates, sampling and testing of the finished stockpile is a crucial step in ensuring product quality meets standards. Currently, common sampling methods include manual shoveling or sampling on the surface of the stockpile or at conveyor belt transfer points. These traditional methods have significant limitations:

[0003] Insufficient representativeness: Surface sampling cannot obtain samples from the interior of the stockpile, especially from different depths. Sand and gravel are prone to segregation during stockpiling, where large and small particles aggregate separately, resulting in significant differences in particle size distribution between the surface and interior. Taking only surface samples cannot accurately reflect the overall quality of the entire batch of material.

[0004] The operation is highly arbitrary: the sampling depth, location and quantity of manual shovel sampling are difficult to standardize and unify, and rely too much on the experience of the operators, resulting in poor repeatability and comparability of sampling results, which affects the accuracy and impartiality of the test data.

[0005] Efficiency and safety issues: Obtaining deep samples often requires the use of machinery to excavate the material pile, which is inefficient, costly, and poses certain safety risks.

[0006] Therefore, there is an urgent need in this field for a sampling device for testing and inspecting finished products from sand and gravel plants that can quickly, accurately, and systematically obtain samples from sand and gravel piles at a specified depth. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a sampling device for testing and inspecting finished products in sand and gravel plants that can quickly, accurately, and systematically obtain samples from sand and gravel piles at a specified depth.

[0008] To solve the above problems, the present invention adopts the following technical solution:

[0009] A sampling device for testing and inspecting finished products in a sand and gravel plant, comprising:

[0010] A sampling tube is provided, with a tube head detachably installed at one end and a holding rod fixedly installed at the other end. By applying force with the holding rod, the tube head is inserted from the surface of the sand and gravel pile to a predetermined depth. A sampling port is provided on the outer wall of the sampling tube. The holding rod is laser-engraved with scales to mark the insertion depth.

[0011] A rotating rod coaxially passes through the holding rod. One end of the rotating rod extends to the outside of the holding rod and is fixed with a vertical handle perpendicular to the axis of the rotating rod. The other end of the rotating rod is inserted into the sampling tube and a sampling cup is detachably installed at this end. The sampling cup has a feed inlet on its wall. When the feed inlet corresponds to the sampling port, the sand and gravel sample falls into the sampling cup through the sampling port.

[0012] A bearing is fitted between the slewing rod and the gripping rod.

[0013] Preferably, the tube head is conical, and the diameter of the tube head gradually decreases in the direction away from the sampling tube.

[0014] Preferably, the end of the sampling tube furthest from the tube head is a tapered portion, and the end of the tapered portion is fixed to the holding rod.

[0015] Preferably, two or more fins are arranged in a ring around the outer wall of the sampling tube, with the axis of the sampling tube as the center point. The fins are inserted into the sand and gravel pile along with the sampling tube to prevent the sampling tube from rotating.

[0016] Preferably, an anti-slip handle sleeve is fixedly fitted at the end of the handle rod, and a marking point is provided on the surface of the anti-slip handle sleeve, the marking point corresponding to the material inlet. A marking arrow is provided at one end of the vertical grip, and when the marking arrow points to the marking point, the material inlet is closed by the cup wall of the sampling cup.

[0017] Preferably, a baffle is provided on the shaft of the rotary rod, and the end of the rotary rod away from the vertical handle is coaxially inserted into the sampling cup. A nut is installed on the end of the rotary rod inserted into the sampling cup. A sealing gasket is sandwiched between the baffle and the sampling cup, and the outer wall of the sealing gasket forms a seal with the inner wall of the sampling tube.

[0018] Preferably, a retaining ring is provided at a position outside the handle rod of the rotary rod, and a bolt is fitted between the retaining ring and the rotary rod.

[0019] The beneficial effects of this utility model are:

[0020] This device, with its graduated handle and sampling tube, allows for precise control of the insertion depth, making it easy to obtain sand and gravel samples from the surface, middle, and even bottom layers of a stockpile.

[0021] This fundamentally solves the industry pain point of insufficient representativeness of surface sampling, and can truly reflect the particle size distribution and quality status of different areas inside the stockpile, providing the most reliable data foundation for quality control.

[0022] It integrates insertion, sampling, and retrieval functions, with a simple and smooth operation process that can be quickly completed by a single person.

[0023] The fins effectively prevent the sampling tube from rotating during insertion, ensuring that the sampling port always faces upwards and avoiding misoperation.

[0024] The open and closed status of the sampling cup is clearly displayed by marking points and arrows, preventing sampling or tipping in the wrong position and further improving the accuracy and success rate of sampling. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] See Figures 1 to 7 The sampling device for testing and inspecting finished products in a sand and gravel plant, as shown, includes:

[0041] The sampling tube 1 has a tube head 2 detachably installed at one end and a holding rod 3 fixedly installed at the other end. By applying force through the holding rod 3, the tube head 2 is inserted from the surface of the sand and gravel pile to a predetermined depth. The outer wall of the sampling tube 1 is provided with a sampling port 11. The holding rod 3 is laser-engraved with scales to mark the insertion depth.

[0042] A rotating rod 4 coaxially passes through the holding rod 3. One end of the rotating rod 4 extends to the outside of the holding rod 3, and a vertical handle 41 is fixed to this end. The vertical handle 41 is perpendicular to the axis of the rotating rod 4. The other end of the rotating rod 4 is inserted into the sampling tube 1, and a sampling cup 5 is detachably installed at this end. The sampling cup 5 has a feed inlet 51 on its wall. When the feed inlet 51 corresponds to the sampling port 11, the sand and gravel sample falls into the sampling cup 5 through the sampling port 11.

[0043] A bearing 42 is fitted between the slewing rod 4 and the holding rod 3.

[0044] The method for sampling sand and gravel particles using this equipment is as follows:

[0045] First, with the sampling port 11 facing upwards, insert the sampling tube 1 into the sand and gravel pile. During the insertion process, hold the handle 3 and apply pushing force through the vertical grip 41 to insert the sampling tube 1 to the predetermined depth.

[0046] After insertion, rotate the vertical handle 41 1 to 3 times to align the feed inlet 51 with the take-up inlet 11, allowing the sand and gravel particles to enter the sampling cup 5.

[0047] Pull the handle 3 outwards to complete the sampling.

[0048] When it is necessary to remove the sample, there are two removal methods:

[0049] The first method involves rotating the feed inlet 51 to correspond with the take-up inlet 11, then turning the take-up inlet 11 downwards and pouring out the sample.

[0050] The second method is to remove the tube head 2 and then pour out the sample from the sampling cup 5.

[0051] Preferably, the tube head 2 is conical, and the diameter of the tube head 2 gradually decreases in the direction away from the sampling tube 1.

[0052] The conical design of the tube head 2 reduces insertion resistance when inserting into a pile of sand and gravel.

[0053] See Figure 1 and Figure 7 As shown, the end of the sampling tube 1 away from the tube head 2 is a tapered portion 121, and the end of the tapered portion 121 is fixed to the holding rod 3.

[0054] The design of the tapered section 121 reduces resistance when exiting the sampling tube 1.

[0055] See Figure 1As shown, two or more fins 131 are arranged in a ring around the axis of the sampling tube 1 on the outer wall of the sampling tube 1. The fins 131 are inserted into the sand and gravel pile along with the sampling tube 1 to prevent the sampling tube from rotating.

[0056] In the above technical solution, the fin 131 is to prevent the sampling tube 1 from rotating and to ensure that the sampling port 11 always faces upward.

[0057] See Figure 1 and Figure 4 As shown, an anti-slip handle sleeve 31 is fixedly fitted at the end of the handle 3. Marking points 32 are provided on the surface of the anti-slip handle sleeve 31, and the marking points 32 correspond to the material inlet 11. A marking arrow 410 is provided at one end of the vertical grip 41. When the marking arrow 410 points to the marking point 32, the material inlet 11 is closed by the cup wall of the sampling cup 5.

[0058] The above technical solution mainly involves marking the position of the material inlet 11.

[0059] See Figure 6 As shown, a baffle 43 is provided on the shaft of the rotary rod 4. The end of the rotary rod 4 away from the vertical handle 41 is coaxially inserted into the sampling cup 5. A nut 44 is installed on the end of the rotary rod 4 inserted into the sampling cup 5. A sealing gasket 45 is sandwiched between the baffle 43 and the sampling cup 5. The outer wall of the sealing gasket 45 forms a seal with the inner wall of the sampling tube 1.

[0060] In the above technical solution, the connection between the sampling device 5 and the rotating rod 4 is completed by installing the nut 44.

[0061] The sealing gasket 45 is designed to prevent fine sand or powder particles from entering the bearing 42.

[0062] See Figure 4 As shown, a retaining ring 46 is provided at a position outside the holding rod 3 on the rotary rod 4, and a bolt 47 is fitted between the retaining ring 46 and the rotary rod 4.

[0063] When an axial thrust is applied through the vertical grip 41, the bearing 42 is prone to dislodging due to force. Therefore, the aforementioned retaining ring 46 is provided. When a thrust is applied, the retaining ring 46 limits the axial displacement of the rotary rod 4 to prevent the bearing 42 from dislodging.
