[0030] refer to Figures 1 to 4 This utility model provides a sample reduction device, which includes a box body 1, a cover body 2, a quartering assembly 3, and a connecting assembly 4. The box body 1 has a receiving cavity 11 for receiving samples. The cover body 2 covers the box body 1. The quartering assembly 3 is detachably disposed between the box body 1 and the cover body 2. The quartering assembly includes four identical partition boxes 31, which are used to divide the receiving cavity 11 into four parts. Each partition box 31 includes a base plate 32 and a side plate assembly 33. The side plate assembly 33 is disposed on the bottom surface of the base plate 32, and the top surface of the base plate 32 is... The cover 2 is detachably connected to the side plate assembly 33, which encloses to form a partition groove 34. The opening of the partition groove 34 faces the bottom of the receiving cavity 11. The side plate assembly 33 extends into the receiving cavity 11 and abuts against the bottom surface of the receiving cavity 11. The connecting assembly 4 includes a locking part 41 and a locking groove 42. The locking part 41 is disposed on the top surface of the base plate 32, and the locking groove 42 is disposed on the bottom surface of the cover 2. The locking part 41 and the locking groove 42 engage. The top surface of the base plate 32 is connected to the cover 2 through the engagement of the locking part 41 and the locking groove 42 to realize the connection between the partition box 31 and the cover 2.

[0031] This invention provides a sample reduction device. By comprising a cover 2, quartering components 3, and a connecting component 4, the sample is mixed when placed in the receiving cavity 11. After the sample is uniformly mixed, the cover 2 and quartering components 3 are detachably connected via the connecting component 4, pressing the four dividing boxes 31 into the receiving cavity 11. After compaction, the box body 1 and cover 2 can be flipped or not, allowing the sample to enter the four dividing boxes 31, thus achieving sample quartering with high uniformity and reducing errors caused by manual sample quartering. Therefore, the sample reduction device of this application can quickly achieve sample quartering, effectively improving sample homogeneity, uniformity, and work efficiency, saving time and effort.

[0032] Specifically, when flipped, the opening of the receiving cavity 11 of the box body 1 faces downward, while the openings of the cover body 2 and the partition box 31 face upward. By setting four independent partition boxes 31, it is beneficial for the sample to flow into the partition box 31 under the action of gravity after flipping. The side wall assembly of the partition box 31 can also effectively prevent cross-contamination between the four samples, reduce sample loss, and reduce error.

[0033] Specifically, the sample is construction sand. The device of this application is used for the index testing of construction sand. With the device of this application, the amount of raw materials required for the index testing of construction sand can be quickly reduced, and the homogeneity of the sand used for testing can be effectively guaranteed when the test data is obtained, thereby improving the accuracy of the test results.

[0034] Furthermore, in the test, the sample can be mixed evenly by connecting the cover 2 and the box 1, and then shaking the cover 2 and the box 1.

[0035] Specifically, the box body 1, cover body 2, four-part components 3 and connecting components 4 are made of stainless steel or other corrosion-resistant metal materials.

[0036] refer to Figures 3 to 4 The side panel assembly 33 includes a first side panel 331, a second side panel 332, and a third side panel 333. The first side panel 331, the second side panel 332, and the third side panel 333 are all disposed at one end of the substrate 32. The second side panel 332 is disposed between the first side panel 331 and the third side panel 333. The first side panel 331 and the third side panel 333 are connected, and the first side panel 331, the second side panel 332, and the third side panel 333 enclose and form a partition groove 34.

[0037] refer to Figure 5 and Figure 6 The bottom of the first side plate 331 and the third side plate 333 are both provided with a bevel 334 so that after the four partition boxes 31 are assembled, the two adjacent first side plates 331 and the two adjacent third side plates 333 each form a cutting edge.

[0038] Specifically, the inclined angle of the slope 334 is 45 degrees. By making a 45-degree inclined slope 334 on the top edge of the first side plate 331 and the third side plate 333, a cutting edge is formed after assembly, which is convenient for dividing the construction sand material.

[0039] refer to Figure 3 and Figure 4 The cavity 11 is cylindrical, the substrate 32 is fan-shaped, and the first side plate 331, the second side plate 332 and the third side plate 333 surround to form a fan-shaped partition groove 34.

[0040] refer to Figure 3 and Figure 4 The substrate 32 and the partition groove 34 are concentrically arranged. The central angle of the substrate 32 is the same as that of the partition groove 34, and the radius of the substrate 32 is greater than that of the partition groove 34, so that the substrate 32 extends radially relative to the partition groove 34 and forms a continuous fan-shaped annular mounting flange 35. When the four partition boxes 31 are assembled together, the four fan-shaped annular mounting flanges 35 surround and form a circle. The annular mounting flange 35 is placed on the top of the box body 1 to support the partition box 31.

[0041] Specifically, the central angle of the substrate 32 and the dividing groove is 90 degrees, the lengths of the first side plate 331 and the third side plate 333 are equal, and the second side plate 332 is arc-shaped.

[0042] Furthermore, the length of the first side plate 331 is less than the radius of the substrate 32, the length of the first side plate 331 is half the diameter of the receiving cavity 11, the radius of the substrate 32 is half the diameter of the cover 2, and the sum of the outer perimeters of the four partition boxes 31 after assembly, that is, the sum of the outer perimeters of the substrate 32, is the inner perimeter of the cover 2.

[0043] In this embodiment, the inner diameter of the box body 1 is 60mm, the radius of the partition groove 34 is 30mm, the depth of the box body 1 is 25mm, and the depth of the partition groove 34 is 25mm.

[0044] refer to Figure 3 The card part 41 and the card slot 42 are matched. The card part 41 includes a first card block 411 and a second card block 412. The bottom surface of the first card block 411 is fixedly connected to the substrate 32, and the top surface of the first card block 411 is connected to the second card block 412. The width of the second card block 412 is greater than the width of the first card block 411, and the center lines of the second card block 412 and the first card block 411 coincide.

[0045] Specifically, the length direction of the first locking block 411 and the second locking block 412 is aligned with the radial direction of the substrate 32, and the width direction of the first locking block 411 and the second locking block 412 is parallel to the horizontal direction. By setting the width of the second locking block 412 to be greater than the width of the first locking block 411, the card part 41 can be prevented from falling out of the card slot 42. When it is necessary to separate the card part 41 from the card slot 42, the card part 41 is moved along the length direction of the first locking block 411 until it disengages from the card slot 42.

[0046] Specifically, when it is necessary to shake the construction sand evenly, the cover 2 can be replaced with a cover 2 without the slot 42, or the slot 42 of the cover 2 can be blocked to prevent the construction sand from entering the slot 42.

[0047] refer to Figure 1 and Figure 3 The reduction device also includes a level 5, which is located on the top surface of the cover 2. The level 5 allows for easy observation of whether the construction sand sample has been cut or flattened.

[0048] refer to Figure 1 and Figure 3 The top surface of the cover 2 is also provided with a mounting groove 21, and the level 5 is disposed in the mounting groove 21. Specifically, the mounting groove 21 and the level 5 are matched to ensure that the level 5 does not wobble on the cover 2. In this embodiment, both the mounting groove 21 and the level 5 are rectangular parallelepipeds.

[0049] refer to Figure 3 The number of connecting components 4 is four, the number of card parts 41 and card slots 42 are four, the four card parts 41 are respectively connected to the base plate 32 of the four partition boxes 31, and the cover 2 is provided with four card slots 42 spaced apart along the circumference, thereby realizing the connection between the four partition boxes 31 and the base plate 32.
