Description

Technical Field

[0001] This utility model relates to the field of soil sampling equipment technology, and specifically discloses a soil sampling device for soil testing. Background Technology

[0002] Soil is fundamental to human survival. Whether it is crops or houses, they are all based on soil. Soil condition surveys are the main means of determining the nature of soil in modern agriculture, geology, water conservancy and environmental protection. Before testing, soil samples must first be taken from a specified soil layer in a designated area, and then the samples are tested. When taking samples, soil sampling equipment is usually used to remove the soil from the ground.

[0003] Existing soil sampling equipment typically involves driving the equipment into a designated soil layer, removing all soil from the surface to that layer, and then selecting soil from the designated layer for testing. When the equipment is driven back into the soil, it first contacts the upper soil layer before contacting the designated layer. Soil from other layers adheres to the equipment's casing, resulting in a small amount of soil from those other layers being mixed into the final soil test results, leading to inaccurate results. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a soil sampling device for soil testing, so as to solve the technical problem that when soil testing is carried out, a small amount of soil from other soil layers will be mixed into the soil being tested due to the limitations of the sampling device, which leads to inaccurate soil test results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a soil sampling device for soil testing, comprising a fixed sleeve, a movable block inserted inside the fixed sleeve, a fixed block at one end of the movable block, the outer wall of the movable block fitting against the inner wall of the fixed sleeve, a gap between the fixed block and the fixed sleeve, and storage cavities formed on both the movable block and the fixed block. The fixed block is provided with several sets of pressure-reducing mechanisms for sealing the storage cavities. A push block is slidably mounted inside the storage cavity, and a connecting block is provided at the other end of the movable block, with one end of the push block threaded onto the connecting block. By controlling the pressure-reducing mechanisms, it can be ensured that no soil appears in the storage cavity before the soil sampling device reaches the designated soil layer. Simultaneously, the pressure-reducing mechanisms can be opened, allowing personnel to collect soil, thus ensuring that the soil sampled by the personnel does not contain soil from other soil layers, thereby guaranteeing the accuracy of the test results.

[0006] Furthermore, the load-reducing mechanism includes an inclined block, on which a hinge seat is provided, and a connecting rod is hinged to the hinge seat. The connecting rod is mounted on the movable block; several sets of inclined blocks form a hollow cone. The load-reducing mechanism makes the top of the soil-boring equipment conical, making it easier for workers to press the soil-boring equipment into the ground.

[0007] Furthermore, the hinge seat is provided with a mating block, and the fixed block has a mating groove and a sliding groove. The mating groove communicates with the sliding groove, and the mating block is slidably engaged in the mating groove, which is S-shaped. By engaging the mating block with the mating groove, when the load-reducing mechanism can move from a separated state to a closed state, several sets of inclined blocks can form a closed cone.

[0008] Furthermore, the inner wall of the fixed groove is provided with several sets of limiting blocks, and the outer wall of the movable block is provided with several sets of limiting grooves. The limiting blocks are slidably engaged within the limiting grooves. The limiting grooves are Z-shaped with 90-degree corners, and both ends penetrate the movable block. The cooperation between the limiting blocks and the limiting grooves allows workers to use the soil-boring equipment more conveniently, ensuring the movable block can only move in one direction within the fixed sleeve, thus facilitating worker control of the movable block.

[0009] Furthermore, the push block is equipped with a first grip, the connecting block is fitted with a movable sleeve, and the movable sleeve is equipped with a second grip; the first grip and the second grip have the same structure and can form a cylinder. The first grip and the second grip cooperate to control the push block and the load-reducing mechanism respectively, without affecting the normal use by the operator.

[0010] Furthermore, the push block is provided with two sets of locking blocks, and the connecting block is provided with two sets of locking slots. The two sets of locking blocks are slidably locked into the two sets of locking slots respectively. The locking slot has an L-shaped cross-section, which appears as a fan-shaped ring when viewed from above, and one end of the locking slot passes through the connecting block. The locking blocks and locking slots cooperate to fix the push block and the connecting block, preventing the push block from moving downwards and removing the soil from the storage cavity when filling with soil.

[0011] The working principle and beneficial effects of this solution are as follows:

[0012] In use, the staff first inserts the soil sampling device into the designated area of ​​soil until the storage chamber moves to the designated soil layer. Then, the staff controls the limiting block to move within the limiting groove, allowing the movable block to move downwards. Next, the staff controls the load-reducing mechanism to open, causing several sets of tilting blocks to move between the fixed block and the fixed sleeve. Then, the staff pushes down the first and second grips, causing the movable block to move downwards, moving the soil into the storage chamber. At this point, there will be no soil from other soil layers in the storage chamber. Once the storage chamber is full of soil, the staff controls the load-reducing mechanism to move back to the initial position, separating the storage chamber from the outside. Then, the staff removes the movable block from the fixed sleeve, and then removes the soil from the storage chamber for soil testing. This process avoids the possibility of inaccurate test results due to the presence of soil from other soil layers in the sample.

[0013] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0021] The following detailed description illustrates the specific implementation method:

[0022] Example

[0023] like Figures 1 to 6 As shown, a soil sampling device for soil testing is disclosed, including a fixed sleeve 1, a movable block 2 inserted inside the fixed sleeve 1, a fixed block 3 at one end of the movable block 2, the outer wall of the movable block 2 being tightly fitted to the inner wall of the fixed sleeve 1, and a gap between the outer wall of the fixed block 3 and the inner wall of the fixed sleeve 1. Both the movable block 2 and the fixed block 3 have storage cavities 11, which are connected. A push block 12 is slidably fitted inside the storage cavity 11, with its periphery tightly fitted to the inner wall of the storage cavity 11. A connecting block 15 is provided at the other end of the movable block 2, and one end of the push block 12 is inserted into the connecting block 15. Two sets of locking blocks 14 are provided on the push block 12. Two sets of locking slots 16 are provided in the connecting block 15, and the two sets of locking blocks 14 are slidably fitted into the two sets of locking slots 16 respectively. The locking slots 16 have an L-shaped cross-section and an arc shape when viewed from above. One end of the locking slots 16 is connected to the storage cavity 11. A first gripping rod 13 is fixedly connected to the push block 12. Figure 2 and Figure 4 As shown.

[0024] The fixed block 3 is equipped with several sets of load-reducing mechanisms arranged in a ring on the fixed block 3. The fixed sleeve 1 is chamfered, which cooperates with the load-reducing mechanisms to facilitate the insertion of the soil-taking equipment into the soil. The fixed block is used to prevent the load-reducing mechanisms from protruding from one end of the fixed sleeve 1. The load-reducing mechanism includes inclined blocks 9, which can form a hollow cone. One end of the inclined blocks 9 contacts the fixed block 3. The inclined blocks 9 are equipped with hinge seats 8, and connecting rods 7 are hinged to the hinge seats 8. The connecting rods 7 are inserted into the movable block 2. The fixed block 3 is provided with a sliding groove 4, and the hinge seats 8 are provided with mating blocks 10. The fixed block 3 is provided with a mating groove 5, which is slidably engaged in the mating groove 5. The mating groove 5 is connected to the sliding groove 4, and one section of the mating groove 5 has an S-shaped cross-section. The several sets of inclined blocks 9 seal the storage cavity 11, such as Figure 3 and Figure 5 As shown.

[0025] The fixed sleeve 1 is provided with several sets of limiting blocks 19, and the outer wall of the movable block 2 is provided with several sets of limiting grooves 20. The limiting blocks 19 are slidably fitted into the limiting grooves 20. The limiting grooves 20 are Z-shaped with 90-degree corners. The limiting blocks 19 and the connecting rods 7 are interleaved, and the limiting blocks 19 and the connecting rods 7 do not interfere with each other. A movable sleeve 17 is fitted on the connecting block 15. The movable sleeve 17 contacts the connecting block 15 and the movable block 2. The outer wall of the movable sleeve 17 contacts the inner wall of the fixed sleeve 1. The other ends of the connecting rods 7 are fixedly connected to the movable sleeve 17. A second gripping rod 18 is provided on the movable sleeve 17. A first gripping rod 13 passes through the movable sleeve 17. The first gripping rod 13 and the second gripping rod 18 have the same structure and can form a complete cylinder. The first gripping rod 13 and the second gripping rod 18 always have one surface in contact. Figure 4 As shown.

[0026] In practice

[0027] In use, the operator first inserts the soil sampling device into the soil. At this time, the load-reducing mechanism is at the front end, and together with the chamfer on the fixed sleeve 1, it pushes the soil at the front of the soil sampling device outwards. The front of the soil sampling device is now conical, facilitating the operator's movement to the designated soil layer. When the soil sampling device is inserted into the soil, the limiting block 19 is located within the limiting groove 20, fixing the movable block 2 to the fixed sleeve 1. When the movable block 2 moves downwards, it can move the fixed sleeve 1. After the top of the soil sampling device reaches the designated soil layer, the operator rotates the first grip 13 and the second grip 18. The first grip 13 and the second grip 18 cause the movable block 2 to rotate within the fixed sleeve 1, causing the limiting block 19 to slide within the limiting groove 20. When the movable block 2 moves downwards, the fixed sleeve 1 remains relatively stationary. Then, the operator controls the load-reducing mechanism to open, causing several sets of tilting blocks 9 to separate. At this time, the storage cavity 11 is connected to the outside. The soil sampling device then... Figure 6 As shown, the staff then simultaneously pushes the first grip 13 and the second grip 18 downwards. At this time, the first grip 13 and the second grip 18 remain relatively stationary. Both the first grip 13 and the second grip 18 drive the movable sleeve 17 to move downwards. The movable sleeve 17 drives the movable block 2 and the fixed block 3 to move downwards. The limiting block 19 slides within the limiting groove 20. When the movable block 2 and the fixed block 3 move downwards, the soil will move into the storage cavity 11. At this time, the soil in the storage cavity 11 is all from the designated soil layer, and no soil from other soil layers will be mixed in. When the soil in the storage cavity 11 is sufficient, the staff controls the load-reducing mechanism to seal the storage cavity 11 from the outside. At this time, the first grip 13 and the second grip 18... With the handle 18 flush with the ground, the soil inside the storage chamber 11 is separated from the external soil. Then, the worker removes the movable block 2 from the fixed sleeve 1, and then removes the soil from the storage chamber 11 for testing. If the worker needs deeper soil samples, the movable block 2 is inserted into the fixed sleeve 1, and the above steps are repeated to sample deeper soil. If the worker does not need deeper soil samples, the fixed sleeve 1 can be removed from the ground. When sampling soil from a specific soil layer, the worker can directly extract the soil from that layer without bringing samples from other soil layers, thus avoiding the possibility of inaccurate test results due to the presence of soil from other layers in the sample.

[0028] When removing the movable block 2, the worker pulls the first lever 13 and the second lever 18 to move the movable block 2 and the fixed block 3 upwards, while simultaneously causing the limiting block 19 to slide within the limiting groove 20 until the limiting block 19 moves to one of the corners of the limiting groove 20. At this point, the structure of the soil removal device is as follows: Figure 4As shown, rotate the first grip 13 and the second grip 18 to rotate the movable block 2 within the fixed sleeve 1, and simultaneously rotate the limiting block 19 within the limiting groove 20 until the limiting block 19 moves to another corner. Then, simultaneously pull the first grip 13 and the second grip 18 upwards, moving the movable block 2 upwards within the fixed sleeve 1, and causing the limiting block 19 to slide within the limiting groove 20. Subsequently, the limiting block 19 separates from the limiting groove 20, and finally the movable block 2 separates from the fixed sleeve 1, allowing the worker to remove the soil from the storage chamber 11. When it is necessary to install the movable block 2 within the fixed sleeve 1, simply reverse the operation of removing the movable block 2 to install it within the fixed sleeve 1.

[0029] When removing the soil from the storage cavity 11, the worker first fixes the movable block 2, then rotates the first gripping rod 13 and the second gripping rod 18, causing the push block 12 and the movable sleeve 17 to rotate. The movable sleeve 17 causes the locking block 14 to move within the slot 16 until the locking block 14 moves to the corner of the slot 16. At this point, the first gripping rod 13 can drive the push block 12 to move within the storage cavity 11. Then, the worker pulls the second gripping rod 18 to control the load-reducing mechanism to connect the storage cavity 11 to the outside, causing the tilting block 9 to move to the outer wall of the fixed block 3. Then, the worker pushes the first gripping rod 13, but the second gripping rod 18 remains stationary. The first gripping rod 13 drives the push block... The pusher 12 moves within the storage cavity 11, simultaneously separating the locking block 14 from the slot 16. The pusher 12 then moves the soil out of the storage cavity 11, allowing the operator to test the soil. The operator then pulls the first lever 13 upwards and presses the second lever 18 downwards, moving both the pusher 12 and the load-reducing mechanism to their initial positions. At this point, the locking block 14 is located within the slot 16. The operator then rotates the first lever 13 and the second lever 18, moving the locking block 14 within the slot 16 and fixing the pusher 12 to the connecting block 15. During soil testing, the soil does not contain any other soil layers, ensuring the authenticity of the soil and thus the accuracy of the test results.

[0030] When the load-reducing mechanism opens, the operator controls the second lever 18 to move the movable sleeve 17 and the connecting rod 7 upwards. The other end of the connecting rod 7 moves the inclined block 9 upwards via the hinge seat 8. During the movement of the inclined block 9, one end of the fixed block 3 remains in contact with the inclined block 9. Simultaneously, the inclined block 9 and the hinge seat 8 rotate around one end of the connecting rod 7. The hinge seat 8 causes the mating block 10 to rotate, and the mating block 10 moves within the mating groove 5. When the inclined block 9 is completely vertical, the mating block 10 is located at the connection between the mating groove 5 and the sliding groove 4. The connecting rod 7 continues to move the hinge seat 8 and the inclined block 9 upwards. At this time, the mating block 10 slides within the sliding groove 4, and the inclined block 9 rises between the outer wall of the fixed block 3 and the inner wall of the fixed sleeve 1 until... The tilting block is completely located in the gap between the outer wall of the fixed block 3 and the inner wall of the fixed sleeve 1. At this time, the storage cavity 11 is connected to the outside world, and the soil can be stored in the storage cavity 11. When it is necessary to control the closing of the load reduction mechanism, the operator controls the second grip rod 18 to move downward. The grip rod drives the movable sleeve 17 and the connecting rod 7 to descend. The connecting rod 7 drives the tilting block 9 to descend. The mating block 10 slides in the sliding groove 4 until the mating block 10 moves to the connection between the mating groove 5 and the sliding groove 4. Then the connecting rod 7 continues to descend, and the mating block 10 slides in the mating groove 5. The mating groove 5 causes the mating block 10 and the hinge seat 8 to rotate around the connecting rod 7. The hinge seat 8 drives the tilting block 9 to move until the tilting block 9 returns to its initial state. At this time, several sets of tilting blocks 9 contact each other and form a cone.

It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model.
