DETAILED DESCRIPTION
[0036] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only 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 skilled in the art belong to the protection scope of the embodiments of the present utility model.
[0037] Please refer to Figure 1 , Figure 1 A three-dimensional structure schematic diagram of a soil sample preparation and material distribution device is provided in the embodiments of the present utility model, and the material distribution device comprises a hopper 1, a material distribution component 2 and a driving mechanism 3.
[0038] The hopper 1 can be provided as an inverted conical structure, such as a quadrangular pyramid or a conical structure. The hopper 1 is used for containing soil particles to be prepared, and the hopper 1 is provided with a discharge port 4 for discharging the soil particles. The discharge port 4 can be arranged at the bottom center of the hopper 1. The soil particles in the hopper 1 are collected to the discharge port 4 under the action of gravity, which is convenient for subsequent discharging.
[0039] The material distribution component 2 can be made of metal material or plastic material, and the processing surface has high smoothness, which is convenient for the distribution of soil particles. The material distribution component 2 is provided with a plurality of material distribution channels 5 distributed radially from the center to the periphery, and the middle part of the plurality of material distribution channels 5 is provided with a blocking part close to the discharge port 4. The cross section of the material distribution channel 5 can be in a U-shaped structure or a V-shaped structure, and the horizontal height of the material distribution channel 5 gradually decreases along the length direction. The radial layout can make the soil particles discharged from the discharge port 4 more evenly distributed into each material distribution channel, so as to achieve the purpose of uniform distribution of materials. As shown in Figure 1 A sampling port 9 can be vertically arranged at the bottom of each material distribution channel 5, which is convenient for the sampling and distribution of soil particles.
[0040] The driving mechanism 3 is arranged at the outer periphery of the hopper 1 or the material distribution component 2. The driving mechanism 3 is used for driving the vertical movement of the hopper 1 and / or the material distribution component 2. When the discharge port 4 is separated from the blocking part to a predetermined distance, the soil particles are evenly distributed to the plurality of material distribution channels 5. The driving mechanism 3 can be a telescopic mechanism driven by a motor, or can be a pneumatic cylinder or an oil cylinder, and can also be configured as a mechanism for lifting the hopper 1. The driving mechanism 3 can separate the hopper 1 and the material distribution component 2 in the vertical direction, and is not limited specifically herein. When the driving mechanism 3 is configured as a telescopic mechanism, a plurality of driving mechanisms 3, for example, 2-4, can be arranged along the axial center line of the hopper 1 in a ring shape based on actual needs. The hopper 1 can be fastened, and the material distribution component 2 is driven to move vertically by the driving mechanism 3. The material distribution component 2 can be fixed, and the hopper 1 is driven to move vertically by the driving mechanism 3. Of course, the hopper 1 and the material distribution component 2 can also be driven to move vertically at the same time, so as to separate them to a predetermined distance.
[0041] The working process of the material distribution device will be described as follows: when the driving mechanism 3 is not started, the soil particles are restricted in the hopper 1 and cannot enter the material distribution channels 5 because the blocking part of the material distribution part 2 is close to the discharge port 4 of the hopper 1. When soil sampling needs to be implemented, the driving mechanism 3 is started, and the driving mechanism 3 drives the hopper 1 and / or the material distribution part 2 to move in the set direction (vertical direction). With the movement, the distance between the discharge port 4 and the blocking part gradually reaches the preset distance. At this time, the soil particles contained in the hopper 1 begin to flow into the multiple material distribution channels 5 distributed radially in the material distribution part 2 under the action of gravity, and then the uniform distribution of soil particles is completed. The whole process does not need manual intervention for material distribution, avoids the material distribution error caused by manual operation, effectively improves the accuracy of soil sampling and material distribution, and enables the subsequent sampling to be better based on the accurate soil particles.
[0042] It should be noted that the number of material distribution channels 5 can be set based on actual needs, and is not specifically limited here. For example, to meet the detection requirements of GB-NY / T1211.1-2006, the material distribution channels 5 can be set to four. Please refer to Figure 2 To make the soil particles flow and distribute evenly, the cross section of the material distribution channel 5 can be set to a V-shaped structure.
[0043] For example, please refer to Figures 1-3 The driving mechanism 3 includes a first telescopic device 12 and a second telescopic device 13.
[0044] The first telescopic device 12 is installed below the hopper 1 and located on one side of the vertical center line of the hopper 1. The second telescopic device 13 is installed below the hopper 1 and located on the other side of the vertical center line of the hopper 1. The first telescopic device 12 and the second telescopic device 13 are used to push the hopper 1 to move synchronously in the vertical direction. The first telescopic device 12 and the second telescopic device 13 are both configured as air cylinders with guide rods. Each air cylinder is connected to an air compressor and a corresponding electromagnetic valve. The first telescopic device 12 and the second telescopic device 13 are controlled to perform synchronous extension and contraction actions through the corresponding electromagnetic valves. The symmetrical layout can provide stable and balanced support force for the hopper 1, ensure that the hopper 1 does not tilt during vertical movement due to uneven force, ensure that the hopper 1 and the blocking part of the material distribution part 2 always maintain a precise relative positional relationship, realize uniform and accurate distribution of soil particles, and ensure the reliability of the hopper 1 during movement.
[0045] It can be understood that when the first and second extenders 12 and 13 are used to lift the hopper 1, the first and second extenders 12 and 13 can be installed under the hopper 1 through the support, the upper edge of the hopper 1 is provided with an outwardly folded outer edge, and the telescopic rods of the first and second extenders 12 and 13 are in close contact with the outer edge of the hopper 1 to lift it. Since soil particles may adhere to the inner wall of the hopper 1 during the sampling process, based on the direct lifting of the hopper 1 by the first and second extenders 12 and 13, the hopper 1 can be lifted and lowered quickly multiple times after the sample is divided by controlling the driving cylinder, so as to apply vibration to the hopper 1, shake off the soil particles adhering to the hopper 1, ensure the cleanliness of the hopper 1, and reduce the possibility of cross-contamination of different types of soil particles during sample division.
[0046] In actual application, during the driving of the hopper 1 to move vertically, the telescopic rods of the first and second extenders 12 and 13 simply rely on the contact with the bottom of the hopper 1 to apply force, which may cause uneven force on the hopper 1. Based on this, the driving mechanism 3 further comprises first and second top blocks 14 and 16. The first top block 14 is installed on the telescopic rod (or piston rod) of the first extender 12, and the first top block 14 is provided with a first fitting part 15 fitted to the outer surface of the hopper 1; the second top block 16 is installed on the telescopic rod of the second extender 13, and the second top block 16 is provided with a second fitting part 17 fitted to the outer surface of the hopper 1. As shown in Figures 1-3 The first and second fitting parts 15 and 17 are arranged according to the outer peripheral curvature of the hopper 1, and the force is uniformly transmitted to the hopper 1 when the hopper 1 is lifted, so as to ensure stable force on the hopper 1 and further improve the stability of the movement of the hopper 1. Of course, two convex points can also be arranged on the first and second top blocks 14 and 16 respectively, and the convex points are used to closely contact the hopper 1 to lift it, so that a multi-point support structure is formed when the first and second extenders 12 and 13 lift the hopper 1. This kind of way can reduce the processing difficulty of the first and second top blocks 14 and 16, and also improve the stability of the lifting of the hopper 1.
[0047] Further, the distance between the discharge port 4 and the blocking part after being separated will affect the flow rate of the soil particles, and the flow rate will affect the sample division accuracy of the soil particles. Based on this, the lifting stroke of the driving mechanism 3 on the hopper 1 can be adjusted, the extension length of the first and second extenders 12 and 13 can be adjusted, and the installation position of the first and second top blocks 14 and 16 can also be adjusted. For example, a first waist-shaped hole movably installed on the first extender 12 is arranged on the first top block 14; a second waist-shaped hole movably installed on the second extender 13 is arranged on the second top block 16. The horizontal installation position of the first top block 14 can be adjusted through the first waist-shaped hole; similarly, the horizontal installation position of the second top block 16 can be adjusted through the second waist-shaped hole, so that the separation distance between the hopper 1 and the blocking part is adjustable. The separation distance can be considered comprehensively based on the sample division time and the sample division accuracy, which will not be described in detail here.
[0048] Since the soil particles are separated based on the material flow channel 5, the soil particles will fall in a dispersed and disordered state, which is easy to cause the soil particles to scatter everywhere. Based on this, in a specific embodiment, the material separating device further comprises a material falling guide plate 10.
[0049] The material falling guide plate 10 is installed at the bottom of the material separating component 2, and a plurality of discharge pipes 18 are provided on the material falling guide plate 10, each of which is connected to each material flow channel 5. Please continue to refer to Figures 1-2 A sampling port 9 can be provided at the bottom of each material flow channel 5, and each discharge pipe 18 is connected to the corresponding sampling port 9. Through the receiving and guiding effect of the material falling guide plate 10, the soil particles flowing out of the material flow channel 5 can be quickly gathered and orderly introduced into the discharge pipe 18, effectively avoiding sample scattering, keeping the working area clean, reducing sample loss, and ensuring the accuracy of sample preparation.
[0050] Further, please refer to Figure 3 , the material separating device further comprises an outer support cylinder 11, which is a hollow pipe structure. The outer support cylinder 11 is sleeved on the material separating component 2, and the top of the outer support cylinder 11 is used to place the hopper 1. A plurality of threaded holes can be provided on the outer periphery of the material separating block 6 of the material separating component 2, and a plurality of through holes corresponding to the threaded holes are provided on the outer periphery of the outer support cylinder 11. The threaded holes are screwed through by bolts, thereby achieving the installation of the outer support cylinder 11 and the material separating component 2. Through the fixed support of the outer support cylinder 11 to the hopper 1 and the material separating component 2, the material separating process can be protected, ensuring that the accuracy of the material separating process is not affected, and effectively improving the reliability of the soil sample preparation and material separation.
[0051] Specifically, the material separating component 2 can be processed as an integrated structure; or it can be processed in a split structure and then assembled into an integrated mechanism, please refer to Figures 4-5 , the material separating component 2 is provided with a material separating block 6 and a blocking block 8, and the split structure can reduce the processing difficulty of the material separating component 2.
[0052] The material separating block 6 is provided with a plurality of upwardly protruding ridges 7 in a central annular array, and the material flow channels 5 are formed between adjacent ridges 7; the blocking block 8 is installed in the middle of the material separating block 6, and the upper part of the blocking block 8 protrudes from the material separating block 6 to form a blocking part. The connection between the blocking block 8 and the material separating block 6 adopts a tight embedded structure, a recessed mounting hole can be processed in the middle of the material separating block 6, and the blocking block 8 is connected to the bottom of the material separating block 6 through fasteners, so as to ensure that the blocking block 8 and the material separating block 6 are seamlessly connected and prevent soil particles from seeping into the gap during the material separating process.
[0053] The upper part of the blocking block 8 is in a conical structure, the top of the conical structure is sharp, and it can be more accurately aligned with the center of the discharge port 4, effectively reducing the problem of loose sealing caused by position deviation during sealing. At the same time, the soil particles can improve the uniformity of the material separation when the soil particles are separated.
[0054] When the soil particles are sampled, the soil particles are automatically discharged from the hopper 1 under the action of gravity, and the soil particles are evenly divided into four parts under the action of the conical head, and the four soil particles are dropped into the four discharge pipes 18 of the discharge guide plate 10 under the action of gravity. Figures 1-3 The discharge guide plate 10 shown includes four discharge pipes 18, two of which are used for sampling, and the other two are used for discarding, and the samples are further processed.
