Description

Technical Field

[0001] The utility model relates to the technical field of soil sample reduction, in particular to a laboratory soil sample reducer. Background Technique

[0002] The main purpose of soil sample reduction is to ensure that while reducing the sample quantity, the representativeness and reliability of the sample are maintained. This helps to reduce the workload of subsequent steps, such as crushing, transportation, etc., thereby accelerating the speed of the entire sample processing. Before each reduction, the sample must be thoroughly mixed to ensure its uniformity. This can be achieved through a mechanical mixer or a specific stirring device. Generally, for soil sample reduction, the air-dried and crushed sample is repeatedly mixed evenly, then spread into a circle, a cross line is drawn through the center of the circle to divide the circle into four equal parts, two diagonal parts are taken, and the other two parts are discarded. Continue to reduce the sample according to this method until the appropriate soil sample for sample preparation is finally left.

[0003] A soil sample reducer is a scientific device specifically designed to reduce a large amount of soil samples into a small amount of representative samples for subsequent testing and analysis. Among them, the mixer usually includes a rotating drum and multiple stirring blades. These designs ensure that the soil samples can be fully mixed during the processing. The layout of the stirring blades and the rotation speed of the rotating drum are carefully calculated to achieve the best mixing effect. Secondly, the quartering device is an important part of the reducer, which is responsible for evenly dividing the fully mixed soil samples into four parts. Through this division, researchers can obtain representative samples, which is crucial for accurate soil analysis.

[0004] However, for common laboratory soil sample reducers, when reducing soil samples, the soil is likely to stay inside the soil sample reducer, resulting in the accumulation of soil inside the sample reducer and blocking the sample reducer. In view of this, this application proposes a laboratory soil sample reducer. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 , a laboratory soil sample quartering device, including an installation base plate 1, a quartering bucket 2 is fixedly installed on the top of the installation base plate 1, a deflector plate 3 is fixedly installed on the inner side wall of the quartering bucket 2, a four-partition bucket 4 is fixedly installed at the bottom of the deflector plate 3, four separation conduits 5 are fixedly installed at the bottom of the four-partition bucket 4, and a vibration anti-blocking assembly 6 for preventing soil samples from staying and blocking is arranged on the side wall of the quartering bucket 2.

[0023] Among them, the vibration anti-blocking assembly 6 includes four movable rods 61 passing through the surface of the quartering bucket 2. End plates 62 are fixedly installed at both ends of the movable rod 61. A spring 63 is fixedly installed on one side of the end plate 62 located inside the quartering bucket 2, and an impact head 64 is fixedly installed on the other side of the end plate 62 located inside the quartering bucket 2. During installation, first pass the movable rod 61 through one side of the quartering bucket 2, then sleeved the spring 63 on the surface of the movable rod 61 located inside the quartering bucket 2, then weld the end plate 62 to both ends of the movable rod 61, and finally weld the impact head 64 to one side of the end plate 62 located inside the quartering bucket 2.

[0024] Secondly, a spring 63 is sleeved on the surface of a movable rod 61 located inside the riffling bucket 2, and one side of the spring 63 is fixedly connected to the inner side wall of the riffling bucket 2. By means of an end plate 62 outside the riffling bucket 2, the movable rod 61 is pulled outwards, the end plate 62 inside the riffling bucket 2 moves, so that the spring 63 is compressed. When the external pulling of the movable rod 61 is released, the impact head 64 repeatedly impacts the quartering bucket 4 under the action of the spring 63, causing the quartering bucket 4 to vibrate and preventing the soil in the quartering bucket 4 from staying.

[0025] Meanwhile, the quartering bucket 4 includes a bucket body 41 fixedly installed at the bottom of the diversion plate 3. A cross partition plate 42 is fixedly installed on the inner side wall of the bucket body 41. Four output holes 43 are formed in the bottom of the bucket body 41. Four diversion blocks 44 are fixedly installed inside the bucket body 41.

[0026] Among them, the four output holes 43 are respectively located at the bottoms of the four regions of the bucket body 41 separated by the cross partition plate 42, and the bottom openings of the diversion blocks 44 are aligned with the output holes 43. The soil enters the bucket body 41, is divided into four parts by the cross partition plate 42, and enters the inside of the separation conduit 5 through the four output holes 43.

[0027] Secondly, a door opening 201 is formed on the surface of the riffling bucket 2. Four sample cups 7 are placed on the top of the mounting base plate 1, and the four sample cups 7 are respectively located at the bottoms of the four separation conduits 5. The soil falls into the four sample cups 7 through the separation conduits 5.

[0028] Meanwhile, a rotating shaft 8 is placed on the top of the riffling bucket 2. A plug 9 is fixedly installed at the bottom end of the rotating shaft 8, and the plug 9 extends into the quartering bucket 4.

[0029] Among them, stirring blades 10 are fixedly installed on the surface of the rotating shaft 8. A top plate 11 is fixedly installed at the top of the rotating shaft 8. The diameter of the top plate 11 is smaller than the inner diameter of the riffling bucket 2. A handle 12 is fixedly installed on the top of the top plate 11. The rotating shaft 8 is placed inside the diversion plate 3, and the plug 9 blocks the quartering bucket 4, so that the soil will not enter the quartering bucket 4. The rotating shaft 8 rotates, driving the stirring blades 10 to rotate, mixing the soil. After mixing is completed, the rotating shaft 8 is picked up through the handle 12, the plug 9 leaves the quartering bucket 4, and the soil enters the quartering bucket 4 for riffling.

[0030] When this embodiment is in use, the rotating shaft 8 is placed inside the diversion plate 3, and the plug 9 blocks the quartering bucket 4. At this time, the soil is put into the coning and quartering bucket 2 from the top of the coning and quartering bucket 2. The staff drives the rotating shaft 8 to rotate by rotating the handle 12, drives the stirring blades 10 to rotate, mixes the soil, then picks up the rotating shaft 8, the plug 9 leaves the quartering bucket 4, and the soil enters the quartering bucket 4 for quartering. After the soil quartering is completed, the vibration anti-blocking component 6 impacts the quartering bucket 4, drives the quartering bucket 4 to vibrate, so that the soil remaining inside the quartering bucket 4 continues to fall, and enters the four sample cups 7 through the separation conduit 5.
