Technical Field

[0001] This utility model specifically relates to a sampling device for testing saline soil, belonging to the technical field of saline soil sampling equipment. Background Technology

[0002] Saline soil refers to soil containing excessive soluble salts or exchangeable sodium ions, which alters its physical and chemical properties and adversely affects plant growth and engineering construction. It is widely distributed in arid and semi-arid regions, coastal areas, and some irrigated agricultural areas around the world. It is a type of soil with special engineering characteristics and ecological impacts. In order to better sample saline soil, a saline soil testing sampling device is needed, such as the saline soil testing sampling device mentioned in authorization announcement number CN219121744U, which includes a base plate, with ground nails slidably connected to the side of the base plate, casters fixedly connected to the bottom surface of the base plate, and sampling components provided on the top surface of the base plate.

[0003] However, existing technologies still have the following problems:

[0004] This device can be used to sample saline soil. During sampling, the location of the sampling device is defined by inserting ground nails into the ground. In actual application, it requires a lot of time for staff, which reduces the efficiency of sampling. After sampling the saline soil, the sampling tube is not easy to rotate as needed. If the saline soil in the sampling tube is not removed in time, it is easy to fall out, which is not user-friendly.

[0005] To address the aforementioned problems, the inventors have proposed a sampling device for testing saline soil. Utility Model Content

A positioning screw is threaded through one side surface of the first vertical plate. A ground-inserting mechanism is provided on one side surface of the first vertical plate. The ground-inserting mechanism includes a first moving block that is slidably connected to one side surface of the first vertical plate. A pressing handle is fixedly connected to one side surface of the first moving block. A second moving block is fixedly connected to one end of the pressing handle. The bottom surface of the second moving block is flush with the first vertical plate. The bottom surface of the moving block is fixedly connected with a grounding rod, and the top surface of the supporting base plate is fixedly connected with a second vertical plate. A guide mechanism is provided on one side of the second vertical plate, and a lifting plate is slidably connected to one side of the second vertical plate. A rotating rod is movably connected to one side of the lifting plate through a bearing. A sampling mechanism is provided at one end of the rotating rod, and limiting mechanisms are provided on both sides of the rotating rod. The limiting mechanism includes a limiting box fixedly connected to the two sides of the rotating rod through a connecting rod. A moving plate is slidably connected to the inner cavity of the limiting box, and a limiting post is fixedly connected through one side of the moving plate. A limiting spring is provided in the inner cavity of the limiting box.

[0008] Preferably, in order to better guide the position of the grounding rod, a fixing block is fixedly connected to the outer surface of the support base plate, and a through hole matching the structural size of the grounding rod is opened through the top surface of the fixing block, and a grounding cone is fixedly connected to the bottom end of the grounding rod.

[0009] Preferably, in order to better improve the stability of the movement of the first moving block and the second moving block, the horizontal cross-section of the first moving block and the horizontal cross-section of the second moving block are both of the U-shaped structure, and guide blocks are fixedly connected to the back-to-back side surfaces of the first moving block and the second moving block, and guide grooves matching the structural dimensions of the guide blocks are opened on the opposite side surfaces of the first vertical plate and the second vertical plate.

[0010] Preferably, in order to better limit the position of the grounding mechanism by means of the positioning screw, a rotating rod is fixedly connected to the outer surface of one end of the positioning screw, and a threaded hole matching the structural size of the positioning screw is opened on one side surface of the first moving block.

[0011] Preferably, in order to better drive the rotation of the lead screw, the guiding mechanism includes a guide box that is fixedly connected to one side surface of the second vertical plate, a servo motor is fixedly connected to the top of the guide box, and the lead screw is provided in the inner cavity of the guide box.

[0012] Preferably, in order to drive the lifting plate assembly to move up and down by rotating the lead screw, one end of the lead screw is fixedly connected to the output end of the servo motor, and the end of the lead screw away from the servo motor is movably connected to the guide box through a bearing. A sleeve block is fixedly connected to one side surface of the lifting plate, and the sleeve block is threadedly connected to the outer surface of the lead screw.

[0013] Preferably, in order to better remove the saline soil inside the sampling tube, the sampling mechanism includes a sampling tube fixedly connected to one end of a rotating rod, an upper and lower rods slidably connected through the top of the sampling tube, a push plate fixedly connected to the bottom of the upper and lower rods, a return spring sleeved on the outer surface of the upper and lower rods, and a pressure plate fixedly connected to the top of the upper and lower rods.

A limiting hole matching the structural size of the limiting column is opened on one side surface of the lifting plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] By setting up a ground-insertion mechanism, which includes a first moving block, a pressing handle, a second moving block, and a ground-insertion rod, guide blocks are fixedly connected to the back-to-back surfaces of the first and second moving blocks. Guide grooves matching the structural dimensions of the guide blocks are opened on the opposite surfaces of the first and second vertical plates. This design allows the first and second moving blocks to slide stably up and down along the guide grooves. The operator only needs to press down the handle to drive the first and second moving blocks to move downward, thereby inserting the ground-insertion rod into the ground. The operation is simple and convenient, improving the efficiency of limiting the position of the sampling device and thus improving the sampling efficiency.

[0017] By incorporating a rotating rod and a limiting mechanism, the sampling mechanism can be easily rotated, ensuring that the opening of the sampling tube faces upwards after sampling. This prevents the saline soil from falling out if it is not removed from the sampling tube in time, making the process more user-friendly. After the rotating rod and sampling mechanism are rotated, the limiting pin in the limiting mechanism re-inserts into the limiting hole on the surface of the lifting plate, thereby limiting the rotating rod and changing the orientation of the sampling tube opening.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6As shown, a sampling device for testing saline soil includes a supporting base plate 1. Rollers 2 are fixedly connected to the four corners of the bottom surface of the supporting base plate 1. A first vertical plate 3 is fixedly connected to the top surface of the supporting base plate 1. A positioning screw 4 is threaded through one side surface of the first vertical plate 3. A rotating rod is fixedly connected to the outer surface of one end of the positioning screw 4. A threaded hole matching the structural dimensions of the positioning screw 4 is opened on one side surface of a first moving block 51. Rotating the positioning screw 4 by the rotating rod can limit the position of the ground insertion mechanism 5 and prevent it from falling easily. A ground insertion mechanism 5 is provided on one side surface of the first vertical plate 3. The ground insertion mechanism 5 includes a first moving block 51 that is slidably connected to one side surface of the first vertical plate 3. A pressing handle 52 is fixedly connected to one side surface of the first moving block 51. A second moving block 53 is fixedly connected to one end of the pressing handle 52. The horizontal cross-sections of the first moving block 51 and the second moving block 53 are both U-shaped. The first moving block 51 and the second moving block 53 are connected in a U-shape. Guide blocks 55 are fixedly connected to the opposite side surfaces of block 53. Guide grooves matching the structural dimensions of guide blocks 55 are opened on the opposite side surfaces of the first vertical plate 3 and the second vertical plate 6. Pressing down the handle 52 will drive the first moving block 51 and the second moving block 53 to move downward. Guide grooves matching the structural dimensions of guide blocks 55 are opened on the opposite side surfaces of the first vertical plate 3 and the second vertical plate 6. Guide blocks 55 slide in the guide grooves, so that the first moving block 51 and the second moving block 53 can slide up and down stably along the guide grooves. Grounding rods 54 are fixedly connected to the bottom surface of the second moving block 53 and the bottom surface of the first moving block 51. Fixing blocks 12 are fixedly connected to the outer surface of the support base plate 1. A through hole matching the structural dimensions of grounding rods 54 is opened on the top surface of fixing blocks 12. Grounding cones are fixedly connected to the bottom end of grounding rods 54. Grounding rods 54 are inserted into the soil through grounding cones to limit the position of the sampling device.

[0027] A second vertical plate 6 is fixedly connected to the top surface of the support base plate 1. A guide mechanism 7 is provided on one side of the second vertical plate 6. The guide mechanism 7 includes a guide box 71 that is fixedly connected to one side surface of the second vertical plate 6. A servo motor 72 is fixedly connected to the top of the guide box 71. A lead screw 73 is provided in the inner cavity of the guide box 71. One end of the lead screw 73 is fixedly connected to the output end of the servo motor 72. The end of the lead screw 73 away from the servo motor 72 is movably connected to the guide box 71 through a bearing. A sleeve block 74 is fixedly connected to one side surface of the lifting plate 8. The sleeve block 74 is threadedly connected to the outer surface of the lead screw 73. The servo motor 72 drives the lead screw 73 to rotate. Since the sleeve block 74 is threadedly connected to the lead screw 73, when the lead screw 73 rotates, the sleeve block 74 will move up and down along the lead screw 73, thereby driving the lifting plate 8 to slide against the side surface of the second vertical plate 6, realizing the lifting movement of the lifting plate 8.

[0028] A lifting plate 8 is slidably connected to one side of the second vertical plate 6. A rotating rod 9 is movably connected to one side of the lifting plate 8 via a bearing. A sampling mechanism 10 is provided at one end of the rotating rod 9. The sampling mechanism 10 includes a sampling cylinder 101 fixedly connected to one end of the rotating rod 9. An upper and lower rod 102 is slidably connected through the top of the sampling cylinder 101. A push plate 103 is fixedly connected to the bottom of the upper and lower rod 102. A return spring 104 is fitted onto the outer surface of the upper and lower rod 102. A pressure plate 105 is fixedly connected to the top of the upper and lower rod 102. After the sampling cylinder 101 samples the saline soil, the worker presses down on the pressure plate 105 fixedly connected to the top of the upper and lower rod 102, which is slidably connected through the top of the sampling cylinder 101. The upper and lower rod 102 moves downward accordingly. The push plate 103, which is fixedly connected to the bottom of the upper and lower rod 102, also moves downward, pushing the saline soil out of the sampling cylinder 101.

[0029] Limiting mechanisms 11 are provided on both sides of the rotating rod 9. Each limiting mechanism 11 includes a limiting box 111 fixedly connected to both sides of the rotating rod 9 via a connecting rod. A movable plate 112 is slidably connected to the inner cavity of the limiting box 111. A limiting post 113 is fixedly connected through one side of the movable plate 112. A pulling rod 115 is fixedly connected to the outer surface of one end of the limiting post 113. The end of the limiting post 113 away from the pulling rod 115 is movably connected through the limiting box 111. The lifting plate 8 is located on one side... The surface is provided with a limiting hole that matches the structural dimensions of the limiting post 113. The limiting post 113 is moved by pulling the pulling rod 115. At this time, the moving plate 112 moves and compresses the limiting spring 114. The limiting spring 114 deforms and generates elastic force. The limiting spring 114 is provided in the inner cavity of the limiting box 111. One end of the limiting spring 114 is fixedly connected to the moving plate 112, and the other end of the limiting spring 114 away from the moving plate 112 is fixedly connected to the limiting box 111.

[0030] It should be noted that: all electrical components in this case, such as the servo motor 72, and their compatible power supplies should be connected by wires by those skilled in the art. In addition, a suitable controller, such as a PLC controller or a microcontroller, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, which outlines the sequential working order of each electrical component to complete the electrical connection. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0031] Working principle: When in use, the staff can easily push the entire saline soil testing sampling device to the target sampling point by using the rollers 2 that are fixedly connected to the four corners of the bottom surface of the support base plate 1.

[0032] Furthermore, the positioning screw 4 is rotated to move it away from the first moving block 51. The operator holds the pressing handle 52 with both hands and presses it down. One end of the pressing handle 52 is fixedly connected to the second moving block 53, and the other end is fixedly connected to the first moving block 51. Therefore, pressing the pressing handle 52 down will drive the first moving block 51 and the second moving block 53 to move down. Since the first moving block 51 and the second moving block 53 are both fixedly connected to the opposite side surfaces, and the opposite side surfaces of the first vertical plate 3 and the second vertical plate 6 are both provided with guide grooves that match the structural dimensions of the guide block 55, the guide block 55 slides in the guide groove, so that the first moving block 51 and the second moving block 53 can slide up and down stably along the guide groove.

[0033] Furthermore, as the first moving block 51 and the second moving block 53 move downwards, the ground-inserting rods 54, which are fixedly connected to their bottom surfaces, also move downwards. A fixing block 12 is fixedly connected to the outer surface of the support base plate 1. A through hole matching the structural dimensions of the ground-inserting rod 54 is opened through the top surface of the fixing block 12. The ground-inserting rod 54 passes through the through hole and is inserted into the ground. A ground-inserting cone is fixedly connected to the bottom end of the ground-inserting rod 54, allowing it to be inserted into the ground more easily, thereby firmly fixing the device at the sampling point.

[0034] Furthermore, after the device is fixed, the staff starts the servo motor 72, which drives the lead screw 73 to rotate. Since the sleeve block 74 is threadedly connected to the lead screw 73, the sleeve block 74 will move up and down along the lead screw 73 when the lead screw 73 rotates, thereby driving the lifting plate 8 to slide against the surface of the second vertical plate 6, realizing the lifting movement of the lifting plate 8, and then adjusting the height of the sampling mechanism 10 connected to the lifting plate 8, inserting the sampling cylinder 101 into the soil to sample the saline soil.

[0035] Furthermore, similarly, the servo motor 72 drives the lead screw 73 to rotate in the opposite direction, removing the sampling cylinder 101 from the saline soil. The staff presses down on the pressure plate 105 fixedly connected to the top of the upper and lower rods 102 that are slidably connected through the top of the sampling cylinder 101. The upper and lower rods 102 move downwards accordingly. The bottom of the upper and lower rods 102 is fixedly connected to the push plate 103, which also moves downwards, pushing the saline soil out of the sampling cylinder 101.

[0036] Furthermore, if the saline soil placement device is not removed in time, the sampling cylinder 101 can be rotated, and the movement of the limiting column 113 can be pulled by the pulling rod 115. At this time, the moving plate 112 moves and squeezes the limiting spring 114. The limiting spring 114 deforms and generates elastic force, and the limiting column 113 leaves the limiting hole on the surface of the lifting plate 8.

[0037] Furthermore, the rotating rod 9 and the sampling cylinder 101 can be rotated so that the opening of the sampling cylinder 101 faces upward. At this time, the pulling rod 115 is released, the limiting spring 114 returns to its original state, and drives the movement of the moving plate 112, so that the limiting post 113 is reinserted into the limiting hole to limit the position of the rotating rod 9.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
