A soil sampling device for forestry protection

Abstract

The present invention relates to the field of soil sampling and detection technology, and specifically to a soil sampling device for forestry protection, comprising a connecting frame, a cylinder is fixedly connected to the top of the connecting frame, and a connecting plate is fixedly connected to the output end of the cylinder. Since the upper end of the rotating shaft is fixedly connected to one end of the push rod one, the rotating shaft drives the push rod one to rotate clockwise when it rotates clockwise, and since the other end of the push rod one is rotatably connected to the sliding block, the sliding block is driven to rotate together when the push rod one rotates clockwise. Due to the limiting effect of the slide rail on the sliding block, the sliding block drives the slide rail to slide on the connecting plate when it rotates. Since the slide rail is rotatably connected to one end of the push rod two, and the other end of the push rod two is rotatably connected to the U-shaped rod, and the two ends of the U-shaped rod are respectively fixedly connected with cover plates, so when the slide rail slides, it pushes the push rod two to rotate, so that the U-shaped rod moves upward and then drives the cover plate to move upward. The soil in the sampling barrel can be compacted by the movement of the cover plate, which is convenient to carry.

Description

Technical Field

[0001] The invention relates to the technical field of soil sampling and detection, in particular to a soil sampling device used for forestry protection. Background Art

[0002] In the work of forestry protection, it is necessary to test the cultivated soil. One of the steps of soil testing is to detect pests or visible impurities in the soil.

[0003] The existing Chinese patent application with publication number CN115993264A is supported on the ground by a support frame, and the connecting belt is installed on the support frame and can move horizontally relative to the support frame. The sampling barrel has a sampling cavity with an opening facing downward and can pass through a first through hole. The sampling barrel can move vertically relative to the support frame and has a sampling position and a sampling position. When the sampling barrel is located at the sampling position, the sampling barrel can extend into the soil on the ground so that the soil adheres to the cavity wall of the sampling cavity, thereby completing the sampling of the soil. When the sampling barrel is located at the unloading position, the sampling barrel is separated from the ground and is located above the connecting belt. The unloading part can move to the bottom of the sampling barrel so that the soil in the sampling cavity can fall onto the unloading part. Since pests and visible impurities in the soil can be observed by the naked eye, the user can directly observe the soil on the unloading part to complete the preliminary detection of the soil, which is convenient and quick.

[0004] However, the invention has the following main disadvantages in actual use:

[0005] 1. After sampling, the soil is relatively loose and not convenient to carry for further monitoring.

[0006] 2. When sampling the soil, the sampling depth is small, and it is not possible to fully understand the impurities on the soil surface. Summary of the invention

The sliding rod is also slidably connected with a plurality of right-angled triangle blocks, and the right-angled triangle blocks are fixedly connected to one end of a primary spring, and the other end of the primary spring is fixedly connected to the sliding rod.

[0018] Furthermore, the secondary driven component includes:

[0019] An annular rod, the annular rod is rotatably connected to the lower end of the connecting plate, the upper end of the annular rod is fixedly connected to a plurality of rectangular blocks, the outer side of the annular rod is fixedly connected to a gear ring, two gears 2 are symmetrically arranged in the radial direction of the gear ring, the gear 2 is meshed with the gear ring, a rotating shaft is slidably connected to the gear 2, the rotating shaft is rotatably connected to the connecting plate, the upper end of the gear 2 is fixedly connected to one end of a reset spring, the other end of the reset spring is fixedly connected to the lower end of the connecting plate, and the reset spring is sleeved on the rotating shaft.

[0020] Furthermore, the edges of the upper ends of the two gears are fixedly connected with push rods, and the middle positions of the front and rear ends of the connecting plate are fixedly connected with right-angled trapezoidal blocks.

[0026] A sampling barrel, the sampling barrel is fixedly connected to the lower end of the connecting plate, the sampling barrel is arranged at the axial position of the annular rod, a soil inlet is opened at the bottom of the sampling barrel, the upper end of the pipe sleeve abuts against the lower end of the sampling barrel, the upper end of the rotating shaft is fixedly connected to one end of the push rod one, the other end of the push rod one is rotatably connected to a slider, the slider is slidably connected to the slide rail, the slide rail is slidably connected to the upper end of the connecting plate, the slide rail is rotatably connected to one end of the push rod two, the other end of the push rod two is rotatably connected to the U-shaped rod, the two ends of the U-shaped rod are respectively fixedly connected to cover plates, and the cover plates are slidably arranged in the sampling barrel.

[0028] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0029] 1. When the slide rail slides to the position corresponding to the triangular lock block at one end of the lock rod, the triangular lock block is pushed open. At this time, the secondary spring is compressed and the slide rail continues to move. When the slide rail is separated from the triangular lock block, the secondary spring is restored, and gear two stops rotating. At this time, the slide rail stops moving. Due to the limiting effect of the triangular lock block, the slide rail is in a stationary state. When the connecting plate moves upward, when the circular top block moves to the position corresponding to the rectangular top block, the rectangular top block squeezes the circular top block to the right, causing the lock rod to move to the right, and the secondary spring is stretched, causing the slide rail to separate from the triangular lock block. Under the action of the reset spring, the slide rail returns to its original position. At the same time, the cover moves downward, causing the cover to squeeze the soil in the sampling barrel, so that the soil sample is compacted.

[0030] 2. When the cylinder extends, the connecting plate moves downward. Since gear one is meshed with the rack, during the downward movement of the connecting plate, gear one rotates clockwise and drives the driven shaft one fixedly connected thereto to rotate. Since the first synchronous wheels are fixedly connected to the two ends of the driven shaft one, the first synchronous wheel is driven to rotate when the driven shaft one rotates. Through the transmission effect of the synchronous belt, the second synchronous wheel fixedly connected to the driven shaft two is driven to rotate, and then the driven shaft two is driven to rotate clockwise. Through the meshing action of gear one and the rack, gear one rolls downward, driving the drill body to rotate downward. When the drill bit is long enough, soil from deeper layers can be obtained, making the soil monitoring more comprehensive.

[0031] 3. Since the upper end of the rotating shaft is fixedly connected to one end of the push rod 1, the rotating shaft drives the push rod 1 to rotate clockwise when it rotates clockwise. Since the other end of the push rod 1 is rotatably connected to the slider, the push rod 1 drives the slider to rotate together when it rotates clockwise. Due to the limiting effect of the slide rail on the slider, the slider drives the slide rail to slide on the connecting plate when it rotates. Since the slide rail is rotatably connected to one end of the push rod 2, and the other end of the push rod 2 is rotatably connected to the U-shaped rod, and the two ends of the U-shaped rod are respectively fixedly connected to the cover plate, the slide rail pushes the push rod 2 to rotate when it slides, so that the U-shaped rod moves upward and then drives the cover plate to move upward. When the push rod on the gear 2 rotates to the position of the right-angle trapezoidal block When the U-shaped rod is lifted up, the push rod is squeezed, causing the second gear to slide downward on the rotating shaft, causing the rotating shaft to disengage from the gear ring. At the same time, due to the rotation of the rotating shaft, the slide rail moves forward until the second gear stops rotating, thereby increasing the angle between the push rod and the slide rail, thereby lifting the U-shaped rod, causing the U-shaped rod to drive the cover plate fixedly connected thereto to move upward until the second gear is completely disengaged from the gear ring. When the soil sampling is completed, the connecting plate moves upward, and the soil is transported and conveyed by the drill body and the anti-falling effect of the pipe sleeve on the soil, so that the soil enters the sampling barrel through the soil material entrance. This arrangement makes soil sampling convenient and quick, and reduces the trouble of manual operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The driven mechanism 4 comprises:

[0053] Two primary driven assemblies 41 are arranged at the front and rear sides of the connecting plate 3 , and a secondary driven assembly 42 is rotatably connected to the center position of the lower end of the connecting plate 3 .

[0054] When sampling the soil, the cylinder 2 is started so that the output end of the cylinder 2 pushes the connecting plate 3 out. During this process, since the cylinder 2 is fixed on the connecting frame 1, the position of the cylinder 2 relative to the connecting frame 1 is stable, and the working effect of the cylinder 2 can be achieved. The output end of the cylinder 2 is fixedly connected to the connecting plate 3, so the cylinder 2 drives the connecting plate 3 to move together when extending and retracting, so that the connecting plate 3 slides on the connecting frame 1. The connecting plate 3 slides on the connecting frame 1, so that the driven component on the connecting plate 3 rotates and drives the secondary driven component 42 to rotate, thereby causing the drill bit to rotate, thereby sampling the soil and transporting the sample soil to the storage component for studying the sample soil.

[0055] The upper end of the connecting plate 3 is fixedly connected to one end of two connecting rods 31, and the other ends of the two connecting rods 31 are respectively fixedly connected to the two ends of the connecting block 32, and the upper end of the connecting block 32 is fixedly connected to the output end of the cylinder 2. Two clamping blocks 33 are longitudinally arranged on the left and right sides of the connecting plate 3.

[0056] Since the output end of the cylinder 2 is fixedly connected to the upper end of the connecting block 32, the two ends of the connecting block 32 are respectively fixedly connected to one end of the two connecting rods 31, and the other ends of the two connecting rods 31 are fixedly connected to the upper end of the connecting plate 3, the connecting block 32 is driven to move together when the cylinder 2 is extended or retracted, and then the connecting block 32 drives the connecting rods 31 and the connecting plate 3 to move together, and the direction of movement is stable and reliable.

[0058] Gear 1 411, the gear 1 411 is fixedly connected to the middle position of the driven shaft 1 412, the driven shaft 1 412 is rotatably connected to the left side of the lower end of the connecting plate 3, the first synchronous wheels 413 are fixedly connected to the positions of the two ends of the driven shaft 1 412, a rack 414 is fixedly connected to the inner side of the left end of the connecting frame 1, the gear 1 411 is meshed with the rack 414, the lower end of the connecting plate 3 is also rotatably connected to the driven shaft 2 415, the driven shaft 2 415 is arranged at the lower right corner of the driven shaft 1 412, the driven shaft 2 415 is fixedly connected to the second synchronous wheel 416 near the two ends, the second synchronous wheel 416 and the first synchronous wheel 413 are driven by a synchronous belt 417.

[0059] When the cylinder 2 extends, the connecting plate 3 moves downward. Since the gear 1 411 is meshed with the rack 414, during the downward movement of the connecting plate 3, the gear 1 411 rotates clockwise and drives the driven shaft 1 412 fixedly connected thereto to rotate. Since the first synchronous wheels 413 are fixedly connected to both ends of the driven shaft 1 412, the first synchronous wheel 413 is driven to rotate when the driven shaft 1 412 rotates. Through the transmission effect of the synchronous belt 417, the second synchronous wheel 416 fixedly connected to the driven shaft 2 415 is driven to rotate, thereby driving the driven shaft 2 415 to rotate clockwise. When the cylinder 2 contracts, the connecting plate 3 moves upward. Since the gear 1 411 is meshed with the rack 414, during the downward movement of the connecting plate 3, the gear 1 411 rotates counterclockwise and drives the driven shaft 1 412 fixedly connected thereto to rotate. Since the first synchronous wheels 413 are fixedly connected to the two ends of the driven shaft 1 412 respectively, when the driven shaft 1 412 rotates, the first synchronous wheel 413 is driven to rotate. Through the transmission effect of the synchronous belt 417, the second synchronous wheel 416 fixedly connected to the driven shaft 2 415 is driven to rotate, thereby driving the driven shaft 2 415 to rotate counterclockwise.

[0060] Reference Figure 3 As shown, the primary driven component 41 also includes:

[0061] The two ends of the driven shaft 2 415 are respectively fixedly connected with push rods 418, and the lower end of the connecting plate 3 is rotatably connected with two L rods 4181, and the two L rods 4181 are arranged on the lower sides of the two ends of the driven shaft 1 412. The lower end of the connecting plate 3 is also slidably connected with two sliding rods 419, and the two sliding rods 419 are respectively arranged on the upper side of the driven shaft 1 412, and the sliding rod 419 is fixedly connected with a convex shaft 4191.

[0062] The two ends of the driven shaft 415 are respectively fixedly connected with push rods 418, so that the driven shaft 415 drives the push rod 418 to rotate together when it rotates. The lower end of the connecting plate 3 is rotatably connected to two L rods 4181, and the two L rods 4181 are arranged on the lower sides of the two ends of the driven shaft 1 412. The lower end of the connecting plate 3 is also slidably connected to two sliding rods 419, and the two sliding rods 419 are respectively arranged on the upper side of the driven shaft 1 412. The sliding rod 419 is fixedly connected with a convex shaft 419, so that the connecting plate 3 drives the L rod 4181, the push rod 418 and the sliding rod 419 to move together during the movement, and the push rods 418 fixedly connected at the two ends of the driven shaft 2 415 are driven to rotate by the rotation of the driven shaft 2 415.

[0063] Reference Figure 4As shown, a slide groove 4182 is provided at one end of the L rod 4181, and a protrusion 4192 is fixedly connected to the sliding rod 419, and the protrusion 4192 is slidably connected in the slide groove 4182, and the other end of the L rod 4181 abuts against the upper side of the end of the push rod 52, and the lower side of the other end of the push rod 418 abuts against the convex shaft 4191, and a plurality of right-angled triangle blocks 4193 are also slidably connected to the sliding rod 419, and the right-angled triangle blocks 4193 are fixedly connected to one end of a primary spring 4194, and the other end of the primary spring 4194 is fixedly connected to the sliding rod 419.

[0064] Since the other end of the L rod 4181 is in contact with the upper side of the push rod 152, and the lower side of the other end of the push rod 418 is in contact with the protrusion 4192, when the push rod 418 rotates clockwise, when one end of the push rod 418 is just disengaged from the protrusion 4192, the other end of the push rod 418 is just in contact with the L rod 4181, so that during the rotation of the push rod 418, the L rod 4181 is pushed to rotate counterclockwise. Since the protrusion 4192 is slidably connected in the sliding groove 4182, the sliding rod 419 is driven to slide leftward when the L rod 4181 rotates counterclockwise. When the push rod 418 is disengaged from the L rod 4181, one end of the push rod 418 is just in contact with the protrusion 4192. The push rod 418 abuts against the shaft 4191, thereby pushing the sliding rod 419 to move to the right. During the counterclockwise rotation of the push rod 418, when one end of the push rod 418 just disengages from the protrusion 4192, the other end of the push rod 418 just abuts against the L rod 4181, thereby pushing the L rod 4181 to rotate clockwise during the rotation of the push rod 418. Since the protrusion 4192 is slidably connected in the slide groove 4182, the L rod 4181 drives the sliding rod 419 to slide to the right when it rotates clockwise. When the push rod 418 disengages from the L rod 4181, one end of the push rod 418 just abuts against the protruding shaft 4191, thereby pushing the sliding rod 419 to move to the left.

[0065] Reference Figure 5 As shown, the secondary driven component 42 includes:

[0066] An annular rod 421, which is rotatably connected to the lower end of the connecting plate 3, and a plurality of rectangular blocks 422 are fixedly connected to the upper end of the annular rod 421, and a gear ring 423 is fixedly connected to the outer side of the annular rod 421, and two gears 424 are symmetrically arranged in the radial direction of the gear ring 423, and the gears 424 are meshed with the gear ring 423, and a rotating shaft 425 is slidably connected to the gear 424, and the rotating shaft 425 is rotatably connected to the connecting plate 3, and the upper end of the gear 424 is fixedly connected to one end of a return spring 426, and the other end of the return spring 426 is fixedly connected to the lower end of the connecting plate 3, and the return spring 426 is sleeved on the rotating shaft 425.

[0067] When the sliding rods 419 at the front and rear ends of the connecting plate 3 slide to the left, the inclined surface of the right-angled triangle block 4193 on the front sliding rod 419 is squeezed by the rectangular block 422, and slides on the sliding rod 419, so that the primary spring 4194 is compressed. At the same time, the right-angled surface of the right-angled triangle block 4193 on the rear sliding rod 419 of the connecting plate 3 is squeezed by the rectangular block 422, and the right-angled triangle block 4193 is stationary relative to the sliding rod 419, pushing the annular rod 421 to rotate counterclockwise. When the sliding rods 419 at the front and rear ends of the connecting plate 3 slide to the right, the rear The inclined surface of the right-angled triangle block 4193 on the end sliding rod 419 is squeezed by the rectangular block 422, and slides on the sliding rod 419, so that the primary spring 4194 is compressed. At the same time, the right-angled surface of the right-angled triangle block 4193 on the sliding rod 419 at the front end of the connecting plate 3 is squeezed by the rectangular block 422. The right-angled triangle block 4193 is stationary relative to the sliding rod 419, pushing the annular rod 421 to rotate counterclockwise, thereby driving the gear ring 423 to rotate, and through the meshing action of the gear ring 423 and gear two 424, gear two 424 rotates clockwise.

[0068] Reference Figure 6 As shown, a push rod 427 is fixedly connected to the edge of the upper end of each gear 424, and a right-angled trapezoidal block 34 is fixedly connected to the middle position of the front and rear ends of the connecting plate 3.

[0069] When the gear 2 424 rotates clockwise, it drives the push rod 427 to rotate. When the push rod 427 rotates to the position of the right-angled trapezoidal block 34, due to the limiting effect of the inclined surface of the right-angled trapezoidal block 34, the push rod 427 drives the gear 2 424 to slide on the rotating shaft 425, the reset spring 426 is stretched, and the gear 2 424 stops rotating.

[0071] The soil drill bit assembly 6 includes:

[0072] The sleeve 61 is fixedly connected to the bracket 4211 . The sleeve 61 is concentrically arranged with the annular rod 421 . The upper end of the sleeve 61 and the inside of the sleeve 61 are fixedly connected with a drill body 62 .

[0073] When the annular rod 421 rotates counterclockwise, it drives the bracket 4211 to rotate together. Since the sleeve 61 and the annular rod 421 are concentrically arranged, and the drill body 62 is fixedly connected to the sleeve 61, when the annular rod 421 rotates, it drives the sleeve 61 and the drill body 62 to rotate together to achieve soil sampling.

[0075] A sampling barrel 51, wherein the sampling barrel 51 is fixedly connected to the lower end of the connecting plate 3, the sampling barrel 51 is arranged at the axial position of the annular rod 421, a soil material inlet 511 is provided at the bottom of the sampling barrel 51, the upper end of the pipe sleeve 61 abuts against the lower end of the sampling barrel 51, the upper end of the rotating shaft 425 is fixedly connected to one end of the push rod 1 52, the other end of the push rod 1 52 is rotatably connected to a slider 53, the slider 53 is slidably connected to a slide rail 54, the slide rail 54 is slidably connected to the upper end of the connecting plate 3, the slide rail 54 is rotatably connected to one end of the push rod 2 55, the other end of the push rod 2 55 is rotatably connected to a U-shaped rod 56, the two ends of the U-shaped rod 56 are respectively fixedly connected to cover plates 57, and the cover plates 57 are slidably arranged in the sampling barrel 51.

[0076] Because the upper end of the rotating shaft 425 is fixedly connected to one end of the push rod 1 52, the rotating shaft 425 drives the push rod 1 52 to rotate clockwise when it rotates clockwise. Because the other end of the push rod 1 52 is rotationally connected to the slider 53, the push rod 1 52 drives the slider 53 to rotate together when it rotates clockwise. Due to the limiting effect of the slide rail 54 on the slider 53, the slider 53 drives the slide rail 54 to slide on the connecting plate 3 when it rotates. Because the slide rail 54 is rotationally connected to one end of the push rod 2 55, and the other end of the push rod 2 55 is rotationally connected to the U-shaped rod 56, and the two ends of the U-shaped rod 56 are respectively fixedly connected with the cover plate 57. Therefore, when the slide rail 54 slides, it pushes the push rod 2 55 to rotate, so that the U-shaped rod 56 moves upward and drives the cover plate 57 to move upward. When the rod 427 rotates to the position of the right-angled trapezoidal block 34, the push rod 427 is squeezed, causing the gear 2 424 to slide downward on the rotating shaft 425, causing the rotating shaft 425 to disengage from the gear ring 423. At the same time, due to the rotation of the rotating shaft 425, the slide rail 54 moves forward until the gear 2 424 stops rotating, thereby increasing the angle between the push rod 2 55 and the slide rail 54, thereby lifting the U-shaped rod 56, causing the U-shaped rod to drive the cover plate 57 fixedly connected thereto to move upward until the gear 2 424 is completely disengaged from the gear ring 423. When the soil sampling is completed, the connecting plate moves upward, and the soil is transported and conveyed by the drill bit body 62 and the anti-falling effect of the pipe sleeve 61, so that the soil enters the sampling barrel 51 through the soil inlet 511.

[0077] The connecting plate 3 is also slidably connected to a locking rod 35, one end of which corresponds to the position of the slide rail 54, one end of which is fixedly connected to a triangular locking block 36, and the other end of which is fixedly connected to a circular top block 37. A secondary spring 38 is sleeved on the locking rod 35, and a rectangular top block 11 is fixedly connected to the connecting frame 1.

[0078] When the slide rail 54 slides to the position corresponding to the triangular lock block 36 at one end of the locking rod 35, the triangular lock block 36 is pushed open, and the secondary spring 38 is compressed at this time, and the slide rail 54 continues to move. When the slide rail 54 is separated from the triangular lock block 36, the secondary spring 38 is restored, and the gear 2 424 stops rotating. At this time, the slide rail 54 stops moving. Due to the limiting effect of the triangular lock block 36, the slide rail 54 is in a stationary state. When the connecting plate 3 moves upward, when the circular top block 37 moves to the position corresponding to the rectangular top block 11, the rectangular top block 11 squeezes the circular top block 37 to the right, so that the locking rod 35 moves to the right, and the secondary spring 38 is stretched, so that the slide rail 54 is separated from the triangular lock block 36. Under the action of the reset spring 426, the slide rail 54 returns to its original position. At the same time, the cover plate 57 moves downward, so that the cover plate squeezes the soil in the sampling barrel 51, so that the soil sample is compacted.
