Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically a deep soil sampler. Background Technology

[0002] A deep soil sampler is a device specifically designed to obtain samples from deeper soil layers. It is typically powered by gasoline or electric power and incorporates a modular design to adapt to complex geological conditions. These tools can quickly penetrate various soil types, including loam, clay, and sand, and maintain the original structure of the sample through a columnar sampling method, avoiding compression and contamination.

[0003] The patent with publication number CN222013561U mentions a deep soil sampler, including a lifting drive device, a steel rope, and a triangular steel pipe frame. A lifting lug is fixedly connected to the end of the steel rope away from the lifting drive device. A drilling cylinder is fixedly connected to the outside of the lifting lug. A slot is formed on the inner side of the drilling cylinder, and a locking block is provided inside the slot. A connecting shaft is provided between a group of locking blocks, and a reversible blade is sleeved on the outside of the connecting shaft. In this invention, the structure composed of the drilling cylinder, the reversible blade, and the cable forms a semi-closed state on the lower cross-section of the cylinder. The soil above the cylinder remains stable under the support of the lower horizontal blade. This enables the deep soil sampler to fix deep, loose soil or soil with high water content inside the sampling tube, solving the problem of weak adhesion between deep soil and the sampling tube, which prevents soil sampling.

[0004] The inventors have discovered at least the following problems in the prior art: The existing deep soil sampler can make the blades press against the loose soil layer by flipping the shaft during use, but it requires an external hand crank to drive it, which will cause the soil to be cut off before it enters the cylinder, thus making it inconvenient to use. In addition, after the collection is completed, since the soil can only be removed from the bottom of the collection tube, some soil will stick to the inside of the tube when the soil is removed, which makes it inconvenient to remove the soil.

[0005] Therefore, this solution provides a deep soil sampler to address the aforementioned problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a deep soil sampler to solve the problems in the existing technology, such as the reliance on external hand-crank drive causing premature soil separation, and the easy adhesion and inconvenience of cleaning when soil is taken from one side of the bottom of the sampling tube.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows: A deep soil sampler includes a drill cylinder mechanism, a connecting mechanism at the top of the drill cylinder mechanism, a sealing mechanism and a driving mechanism inside the drill cylinder mechanism, the sealing mechanism being located at the bottom of the driving mechanism; the drill cylinder mechanism includes a drilled cylinder body, the connecting mechanism includes a connecting cover; the sealing mechanism includes a support frame and four flaps arranged around the support frame, and a knob is provided at the bottom of the support frame; the driving mechanism includes a top plate and a connecting column fixedly connected to the bottom of the top plate, and a linkage plate slidably connected around the connecting column.

[0009] Preferably, the bottom of the connecting column is fixedly connected to a support frame, the support frame has a through hole extending vertically, the top of the connecting column has a notch, and a pressure plate is slidably connected vertically inside the connecting column.

[0010] Preferably, two symmetrical sliding blocks are slidably connected below the top plate, and a connecting rod is rotatably connected below the sliding blocks. The connecting rod is located inside the notch, and the bottom of the connecting rod is rotatably connected above the pressure plate.

[0011] Preferably, the bottom of the pressure plate is fixedly connected to four evenly distributed racks, the bottom of the racks are through holes, and the top of the linkage plate is fixedly connected to two symmetrical abutments, the top of the abutments engaging with the outer periphery of the connecting rod.

[0012] Preferably, a flap shaft is fixedly connected to one side of the flap, a gear is fixedly connected to one end of the flap shaft, the gear meshes with a rack, the flap shaft and the gear are rotatably connected inside the support frame, a limit block is fixedly connected to the outside of the support frame, the limit block cooperates with the flap, and the top of the knob is fixedly connected to the rack.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] According to the appendix Figure 1 - Figure 5 As shown, this utility model provides a deep soil sampler, including a drill cylinder mechanism 1, a connecting mechanism 2 is provided at the top of the drill cylinder mechanism 1, and a sealing mechanism 3 and a driving mechanism 4 are provided inside the drill cylinder mechanism 1. The sealing mechanism 3 is located at the bottom of the driving mechanism 4. Drilling mechanism 1 includes a drilling cylinder 11, and connecting mechanism 2 includes a connecting cover 21; The blocking mechanism 3 includes a support frame 31 and four flaps 35 arranged around the support frame 31. A knob 34 is provided at the bottom of the support frame 31. The drive mechanism 4 includes a top plate 41 and a connecting column 43 fixedly connected to the bottom of the top plate 41. A linkage plate 44 is slidably connected to the periphery of the connecting column 43. The drill cylinder mechanism 1 is a collection cylinder used in the prior art to carry the collected soil.

[0022] In a further embodiment, the bottom of the connecting cover 21 is provided with a quick-release slot 22 that is evenly distributed around it, and the top of the top plate 41 is fixedly connected with a card block 42 that is evenly distributed around it, and the card block 42 fits into the quick-release slot 22.

[0023] In this embodiment, the card block 42 can be inserted into the quick-release slot 22 first, and then the top plate 41 can be rotated so that the card block 42 can engage with the quick-release slot 22, thereby allowing for quick disassembly and removal of the soil from the bottom of the linkage plate 44 and the support frame 31 and the flip plate 35.

[0024] In a further embodiment, a support frame 31 is fixedly connected to the bottom of the connecting column 43. The support frame 31 has a through-hole 33, and a notch 431 is opened at the top of the connecting column 43. A pressure plate 48 is slidably connected to the inside of the connecting column 43.

[0025] In this embodiment, the connecting column 43 has a hole with the same diameter as the pressure plate 48 inside, so that the pressure plate 48 can slide.

[0026] In a further embodiment, two symmetrical slide blocks 46 are slidably connected below the top plate 41, and a connecting rod 47 is rotatably connected below the slide blocks 46. The connecting rod 47 is located inside the notch 431, and the bottom of the connecting rod 47 is rotatably connected above the pressure plate 48.

[0027] In this embodiment, the top plate 41 is provided with a spring in the groove where the slide block 46 slides, so that the two slide blocks 46 are always kept away from each other, thereby keeping the connecting rod 47 in an inclined state.

[0028] In a further embodiment, four evenly distributed racks 49 are fixedly connected to the bottom of the pressure plate 48, the bottom of the racks 49 are through the insertion hole 33, and two symmetrical abutments 45 are fixedly connected to the top of the linkage disc 44, the top of the abutments 45 are engaged with the periphery of the connecting rod 47.

[0029] In this embodiment, the abutment 45 is closely attached to the outer periphery of the connecting column 43, and in conjunction with the inclined connecting rod 47, the slide 46 will move towards the center when the linkage plate 44 and the abutment 45 move upward, and then the pressure plate 48 and the rack 49 will be pressed down by one end of the connecting rod 47.

[0030] In a further embodiment, a flap shaft 36 is fixedly connected to one side of the flap 35, and a gear 37 is fixedly connected to one end of the flap shaft 36. The gear 37 meshes with a rack 49. Both the flap shaft 36 and the gear 37 are rotatably connected inside the support frame 31. A limit block 32 is fixedly connected to the outside of the support frame 31. The limit block 32 cooperates with the flap 35. The top of the knob 34 is fixedly connected to the rack 49.

[0031] In this embodiment, the bottom of the knob 34 has a protrusion for easy rotation, and its top has four pillars that can engage with the rack 49. When the rack 49 moves down, the knob 34 moves down synchronously. During the downward movement of the rack 49, the gear 37 rotates, thereby causing the flap 35 to rotate and close the periphery of the support frame 31, thereby cutting off the soil from the bottom of the borehole cylinder 11 and sealing it. The limiting block 32 is used to limit the flap 35 after it rotates.

[0032] In a further embodiment, the connecting cover 21 is bolted to the top of the drilled cylinder 11, and a connecting piece 23 is fixedly connected to the top of the connecting cover 21. Drill teeth 13 are provided at the bottom of the drilled cylinder 11, and a limiting ring 12 is fixedly connected to the inner side of the drilled cylinder 11. The limiting ring 12 is located above the periphery of the support frame 31.

[0033] In this embodiment, the connector 23 is used to connect to the output end of an external drilling device, thereby allowing the connector 2 and the drill barrel mechanism 1 to rotate into the borehole for data collection.

[0034] The working principle of this utility model is as follows: When the connector 23 connects to the external drilling equipment, the connecting mechanism 2 and the drill cylinder mechanism 1 are inserted into the deep hole, allowing the soil in the deep hole to enter the interior of the drill cylinder 11. At this time, the soil will pass around the sealing mechanism 3 and continuously push up the linkage plate 44, causing the linkage plate 44 to move upward until the abutment 45 at the top of the linkage plate 44 contacts the outer periphery of the connecting rod 47. This will cause the slide 46 at the top of the connecting rod 47 to move towards the center, and then the other end of the connecting rod 47 will be pressed downward, causing the pressure plate 48 and the rack 49 to slide downward inside the connecting column 43. This will cause the bottom end of the rack 49 to mesh with the gear 37, causing the flap 35 to rotate around the flap shaft 36, thereby closing the periphery of the support frame 31. Thus, the closing can be performed automatically without manual control, sealing the bottom of the drill cylinder 11, making it more convenient to use and avoiding empty sampling. In addition, after the collection is completed, the support frame 31, the connecting column 43 and the top plate 41 can be rotated by rotating the knob 34, so that the card block 42 can be released from the restriction of the quick release slot 22. Then, by pulling the knob 34, the soil collected between the support frame 31 and the flip plate 35 and the linkage plate 44 can be quickly and easily removed.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
