Technical Field

[0001] The utility model relates to the technical field of soil sampling, and more specifically to a soil sampling device for the acceptance of soil and water conservation work. Background Art

[0002] Soil and water conservation is the cause of preventing and controlling soil erosion, protecting, improving and rationally using soil and water resources, improving land productivity, and establishing a good ecological environment. It refers to the preventive and control measures taken for soil erosion caused by natural factors and human activities. In the acceptance operation of soil and water conservation work, it is usually necessary to use a soil sampling device to sample the soil for subsequent monitoring and acceptance.

[0003] A soil sampling device for the acceptance of soil and water conservation work with the publication number of CN219573555U includes a carrier plate. Handlebars are evenly distributed on both side walls of the carrier plate. A driving motor is fixed in the middle of the lower end of the carrier plate. A sampling cylinder is installed at the lower end of the driving motor. A soil receiving cavity is formed in the sampling cylinder. Drill teeth are evenly distributed at the lower end of the sampling cylinder. Laser distance sensors are installed on both sides of the lower end of the carrier plate. The beneficial effects are as follows: Through the design of the carrier plate, handlebars, control unit, driving motor, sampling cylinder and laser distance sensor, the soil sampling device can use electronic equipment to measure the sampling depth.

[0004] When the soil sampling device proposed in the above patent document is actually used, after sampling the soil, the sampling cylinder needs to be directly pulled out of the soil. However, since the bottom of the sampling cylinder is an open structure, part of the soil will fall from the bottom of the sampling cylinder when the sampling cylinder moves upward, resulting in incomplete sampled soil and increasing the operation difficulty of soil sampling. Therefore, it is necessary to improve the disadvantages of this sampling device. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] Referring to Figures 1-5 , the present utility model provides a soil sampling device for the acceptance of soil and water conservation work, including a support base 1. A fixed frame 2 is fixedly connected to the upper surface of the support base 1. A driving mechanism 3 is arranged on the upper surface of the fixed frame 2, and a driving screw 9 is rotatably arranged on the lower surface of the fixed frame 2. A driving motor 302 is fixedly installed on the upper surface of the driving box 301. The output shaft of the driving motor 302 extends into the interior of the driving box 301 and is fixed with a driving gear 303. The top end of the driving screw 9 extends into the interior of the driving box 301 and is fixedly connected with a driven gear 304. The driving gear 303 meshes with the driven gear 304.

[0028] A lifting sleeve 4 is threadedly connected to the surface of the driving screw 9. Two limiting rods 12 are fixedly connected to the lower surface of the fixed frame 2.

The size of the limiting through holes matches that of the limiting rods 12. The limiting movable plate 13 is slidably connected to the surface of the limiting rods 12 through the limiting through holes.

[0029] It should be noted that when the lifting sleeve 4 moves up and down, it drives the limiting movable plate 13 to slide on the surfaces of the two limiting rods 12, which can play a role in limiting and guiding the lifting sleeve 4, so that the lifting sleeve 4 maintains a vertical movement, facilitating sampling at different depths in the soil.

[0030] A sampling cylinder 5 is fixedly connected to the bottom end of the lifting sleeve 4. A plurality of pointed blocks 11 are fixedly connected to the bottom end of the sampling cylinder 5. The plurality of pointed blocks 11 are evenly distributed in a circular array at the bottom end of the sampling cylinder 5. By providing the plurality of pointed blocks 11, it is convenient to insert the sampling cylinder 5 into the soil.

[0031] Scale lines are fixedly arranged on the surface of the sampling cylinder 5. The sampling cylinder 5 is used for sampling soil. Through the above technical solutions, after the sampling cylinder 5 is inserted into the soil, the staff can adjust the insertion depth of the sampling cylinder 5 by observing the scale lines.

[0032] It should be noted that by setting the driving mechanism 3, the driving screw 9 and the lifting sleeve 4, when sampling the soil, first, the driving motor 302 drives the driving gear 303 to rotate, which in turn drives the driven gear 304 and the driving screw 9 to rotate, and then drives the lifting sleeve 4 to move downward on the surface of the driving screw 9. The lifting sleeve 4 drives the sampling cylinder 5 to move downward and insert into the soil. The staff controls the sampling depth by observing the scale line on the surface of the sampling cylinder 5.

[0033] A limiting mechanism 6 is arranged on the inner wall of the sampling cylinder 5. The limiting mechanism 6 is used to squeeze and limit the sampled soil. The limiting mechanism 6 includes an annular limiting shell 601 fixedly connected to the inner wall of the sampling cylinder 5. Two symmetrically positioned rectangular mounting holes 602 are formed on the surface of the annular limiting shell 601. A rubber air cushion 603 is fixedly connected to the inner wall of the rectangular mounting hole 602. A communicating air pipe is fixedly arranged between the two rubber air cushions 603. By arranging the communicating air pipe between the two rubber air cushions 603, the two rubber air cushions 603 can be internally communicated with each other through the communicating air pipe.

[0034] An air inlet connecting pipe 604 is fixedly embedded in the upper surface of the sampling cylinder 5. The bottom end of the air inlet connecting pipe 604 extends into the interior of one rubber air cushion 603. A one-way air inlet valve 607 is fixedly arranged on the surface of the air inlet connecting pipe 604. The one-way air inlet valve 607 is used for one-way air inlet into the rubber air cushion 603.

[0035] The driving mechanism 3 includes a driving box 301. An air pump 7 is fixedly arranged on the inner wall of the driving box 301. The output end of the air pump 7 is fixedly provided with an air inlet pipe 10. The air inlet end of the air inlet pipe 10 away from the air pump 7 extends to the outside of the driving box 301. The output end of the air pump 7 is fixedly connected with a guiding air hose 8. The end of the guiding air hose 8 away from the air pump 7 extends to the outside of the driving box 301 and is fixedly connected to the input end of the air inlet connecting pipe 604.

[0036] An exhaust pipe 605 is fixedly embedded in the upper surface of the sampling cylinder 5. The bottom end of the exhaust pipe 605 extends into the interior of the other rubber air cushion 603, and a pressure relief valve 606 is fixedly arranged on the surface of the exhaust pipe 605.

[0037] After inserting the sampling cylinder 5 into the specified sampling depth on the ground, the air pump 7 can be used to generate gas, and the gas is transported into the two rubber air cushions 603 inside the sampling cylinder 5 through the air guide hose 8. The rubber air cushions 603 expand after being inflated, so as to use the two rubber air cushions 603 to squeeze the soil in the sampling cylinder 5, and then generate two opposite-direction pressures on the soil, so that the soil is squeezed and limited inside the sampling cylinder 5, so that the soil is not likely to fall during the upward movement of the sampling cylinder 5. Then, reverse the drive motor 302, use the drive screw 9 to drive the sampling cylinder 5 to move upward and reset, take out the sampling cylinder 5 from the ground, and then open the pressure relief valve 606 on the surface of the exhaust pipe 605 to relieve the pressure and deflate the rubber air cushion 603, so as to facilitate the staff to unload the soil in the sampling cylinder 5.

The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
