Description

Technical Field

[0001] This utility model relates to the field of soil sampling device technology, and in particular to a convenient agricultural soil sampling device. Background Technology

[0002] Soil sampling is a crucial step in soil information acquisition technology. To determine the sufficiency of soil nutrients in an overall area, it is necessary to correctly collect soil samples and conduct tests and analyses. Statistical methods are generally used to analyze the statistical values ​​of the sample test results in order to estimate the nutrient status of the entire area.

[0003] In current rural areas, soil sampling is typically carried out using a support frame to hold the soil sampler in place. The screw is then rotated to extend the sampler deeper into the soil for sampling. However, in practice, rural soil becomes quite loose due to prolonged cultivation. When supported by the frame, the frame is prone to tilting, which affects the accuracy of the sampling and presents certain shortcomings.

[0004] Therefore, a convenient soil sampling device for agricultural use is provided to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to provide a convenient agricultural soil sampling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example:

[0029] Reference Figure 1-4 A convenient agricultural soil sampling device includes a mounting plate 1, and further includes: a lead screw 2 threadedly connected to the mounting plate 1, with a soil sampler 4 connected to one end of the lead screw 2; multiple sets of support legs 101 rotatably connected to the mounting plate 1; a sliding block 5 connected to the support legs 101, with a cavity inside the sliding block 5; a slot 502 disposed on the sliding block 5, communicating with the cavity; a ground nail 6 slidably connected within the cavity; a spring 8 sleeved on the ground nail 6, located within the cavity, which can compress and stretch the spring 8 by the movement of the ground nail 6 within the cavity; and a locking block 7 fixedly connected to the ground nail 6. 7 can enter the slot 502. The support leg 101 is provided with a sliding groove 102. The sliding block 5 is slidably connected in the sliding groove 102. The support leg 101 is provided with two sets of limiting grooves 103. The sliding block 5 is provided with an insertion hole 501. The screw 9 is slidably connected in the insertion hole 501. The screw 9 is threadedly connected in the limiting groove 103. The screw rod 2 is fixedly connected to the mounting base 201. The soil sampler 4 is threadedly connected in the mounting base 201. The screw rod 2 is threadedly connected to the screw rod 3. One end of the screw rod 3 is located in the soil sampler 4. A pusher block is fixedly connected to the end of the screw rod 3 located in the soil sampler 4. Both the screw rod 2 and the screw rod 3 are connected to handles.

[0030] The support leg 101 in this device has a limited range of rotation within the mounting plate 1, which facilitates storage and support for use.

[0031] In practical use, the soil sampler 4 is installed in the mounting base 201. Then, the device can be moved to the rural land to be sampled, and the support leg 101 is rotated. Figure 1As shown, make the mounting plate 1 as level as possible with the ground. Then, rotate and remove the screw 9, which was initially located in the upper limiting groove 103. Next, pull the locking block 7 upwards to place the ground nail 6 into the cavity. At this time, the spring 8 is in a compressed state. Then, rotate the locking block 7 to lock it into the locking groove 502. Now, move the sliding block 5 downwards to make it contact the ground. At this time, the insertion hole 501 is coaxial with the lower limiting groove 103. Then, the sliding block 5 can be adjusted using the screw 9. Once fixed, the locking block 7 can be rotated out of the locking slot 502. At this time, under the action of the spring 8, the ground nail 6 will quickly extend from the sliding block 5 and enter the ground, thereby increasing the stability of the support leg 101 with the ground. After all three sets of support legs 101 are fixed, the screw rod 12 can be rotated to sample through the soil sampler 4. After sampling, the screw rod 12 is reversed to pull the soil sampler 4 out of the soil. Then, the soil extracted by the soil sampler 4 is squeezed out by rotating the screw rod 23. At this time, the sampling is completed.

[0032] After sampling is completed, the slider 5 is reset and can then be moved to sample the next location.

[0033] The spring component 8 of this device can be elongated instead of compressed, and the specific method can be selected according to the requirements.

[0034] This utility model utilizes a ground stake 6 that slides within a sliding block 5. During use, by pulling the ground stake 6, the spring 8 causes the ground stake 6 to move quickly, allowing it to be quickly inserted into the soil. This improves the stability of the support leg 101, reduces the possibility of tilting, and facilitates its use in rural soil sampling.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
