Description

Technical Field

[0001] This utility model relates to a sample inspection and reduction operation device, and in particular to a handheld sample cutting and reduction device. Background Technology

[0002] Iron ore, coal, alloys, etc. are important raw materials for the steel industry. When conducting inspections, they need to be crushed, mixed multiple times, and reduced to the required sample size before being tested.

[0003] To ensure the sample quantity meets the requirements for sample preparation and testing, Sample 01 needs to be thoroughly mixed before the sample quantity for sample preparation and testing is determined through a reduction operation. Currently, in China, the reduction of Sample 01 is generally performed using the conical quartering method (cross reduction method) or the divisor reduction method. The conical quartering method is complex and labor-intensive; while the divisor reduction method has limitations and is not suitable for wet or viscous substances. Existing conical quartering methods (such as...) Figure 1 As shown), the mixed sample 01 is shaped into a frustum cone, and then divided into four nearly equal parts along lines A and B (e.g., Figure 2 As shown in the figure, portions a and c are combined into sample ac, and portions b and d are combined into sample bd. If the sample size of sample ac or sample bd is too large and still cannot meet the requirements for sample preparation and testing, then sample ac or sample bd needs to be further reduced until sample 01 meets the requirements for sample preparation and testing.

[0004] The above methods are complex and labor-intensive, especially when dealing with wet or viscous substances, where the reduction process is extremely tedious. To date, there are no simple, rapid reduction devices or methods available, nor are there any published papers on them. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a handheld sample cutting and reducing device that, while fulfilling the reducing function, solves the shortcomings of traditional conical quartering and dichotomous reducing methods when reducing wet and viscous substances, thereby achieving the goals of meeting reducing requirements, reducing the labor intensity of employees, and improving work efficiency.

[0006] The purpose of this utility model is achieved as follows: A handheld sample cutting and reducing device includes a cutter and a tray below the cutter. The cutter is equipped with a frame and a handle. The frame is composed of a cutting plate and a tail plate arranged parallel to both sides, and the discharge port is an open design. The tray has closed panels on three sides and an opening on one side. The cutter is placed inside the tray, and the discharge port of the cutter is on the same side as the opening.

[0007] Furthermore, the cutter has at least two frames arranged in parallel, and the width of the frame is equal to the distance between the outer walls of the adjacent cutting plates between the frames.

[0008] Furthermore, the inner width of the tray is greater than the width of the cutter, with the extra width being the width of an inner groove in the frame.

[0009] This invention possesses all the functions of the conical quartering method (cross-shaped reduction method) and the divisor reduction method. It uses the divisor to cut the sample into multiple strips, meeting the sample reduction volume requirements. At the same time, it solves the shortcomings of the traditional conical quartering method and divisor reduction method when reducing wet and viscous substances, thus achieving the purpose of meeting the reduction requirements, reducing the labor intensity of employees, and improving work efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. See also Figure 3 , Figure 4 , Figure 5 and Figure 6A handheld sample cutter / reducer includes a cutter 1 and a tray 2 below the cutter 1. The cutter 1 is equipped with a frame 11 and a handle 12. The frame 11 is composed of cutting plates 101 and a tail plate 102 arranged parallel to each other on both sides, and the discharge port 103 is an open design. There are at least two frames 11 in the cutter 1, which are arranged parallel to each other. The width inside the frame 11 is equal to the distance between the outer walls of the adjacent cutting plates 101 between the frames 11. The handle 12 is connected to the upper middle section of the frame 11. The cutting plates 101 of the frame 11 are parallel to each other and perpendicular to the bottom surface of the tray 2. The tray 2 is equipped with closed panels on three sides and an opening 201 on one side. The cutter 1 is placed inside the tray 2, and the discharge port 103 of the cutter 1 is on the same side as the opening 201. The inner width of the tray 2 is greater than the width of the cutter 1, and the extra width is the width of the inner groove of the frame 11, to ensure that the remaining sample 3 and the sample of the reduction waste 4 are equal after reduction.

[0018] Example: In operation, sample 01 is first mixed and spread evenly in tray 2. The operator holds handle 12 and inserts cutter 1 into sample 01 mixed and spread evenly in tray 2 along one side wall of tray 2, ensuring that the bottom surface of frame 11 in cutter 1 is in contact with the bottom surface of tray 2, dividing sample 01 into multiple strips. The operator then holds handle 12 and pushes cutter 1 towards opening 201 of tray 2, removing the reduced waste material 4 cut from cutter 1 out of tray 2. The sample at the interval in tray 2 is the remaining sample 3 after reduction (e.g., Figure 6 As shown), the final goal is to reduce the sample size of sample 01. This utility model is a combined structure, consisting of a cutter 1 and a tray 2. The cutter 1 is equipped with a frame 11 and a handle 12. The frame 11 is composed of cutting plates 101 and a tail plate 102 arranged parallel to both sides, and the discharge port 103 is an open design. The handle 12 is connected to the upper middle section of the frame 11 by welding or bolting. The tray 2 has closed panels on three sides and an opening 201 on one side. The cutter 1 is placed inside the tray 2, and the discharge port 103 of the cutter 1 is on the same side as the opening 201. During manufacturing, the height of the frame 11 in the cutter 1 should be greater than the height of the panels of the tray 2 to ensure that the material does not overflow from the top surface of the frame 11.

[0019] After processing with a handheld sample cutter and reducer, the shortcomings of traditional conical quartering and dichotomy methods for reducing wet and viscous substances are resolved. This improves work efficiency and reduces the labor intensity of operators.

[0020] This invention enables the cutting and reduction of samples, especially for wet and viscous substances, achieving rapid separation while facilitating the cleaning of the reduction tools. This reduces sample mixing and contamination, thus achieving a practical and efficient working goal. It can be used in industries such as mining, docks, steel, coking, coal, metallurgy, and chemicals for sample reduction during sampling and testing.
