Description

Technical Field

[0001] The utility model relates to the technical field of agricultural technology detection, and more specifically to a soil sampling device for agricultural technology detection. Background Art

[0002] The soil sampling process in agricultural technology testing refers to the collection of soil samples on agricultural land for soil quality testing. Before collecting the soil, the soil surface needs to be repaired and cleaned, and then the soil is sampled layer by layer from top to bottom. At present, the sampling device in the existing technology often uses a whole circular tubular structure to be manually inserted into the soil for sampling.

[0003] Chinese patent authorization announcement number: CN216361688U provides a soil sampling device for agricultural technology detection. The baffle is extended under the action of a reset spring to close the transmission cavity to prevent the soil collected inside the hollow threaded rod from falling during the lifting process of the hollow threaded rod and the drill bit, resulting in collection failure.

[0004] However, soil sampling and testing usually involves sampling the soil layer by layer from top to bottom, and observing and testing each layer of soil separately. Although the transmission cavity in this scheme can squeeze multiple layers of soil into its inner cavity during the sampling process, it is difficult to completely remove the multiple layers of soil in the inner cavity after sampling. If the soil is poured out by knocking or shaking, the layering of the soil will be destroyed, making it inconvenient to perform layered testing on the extracted soil. Therefore, in view of the above problems, a soil sampling device for agricultural technology testing is proposed. Utility Model Content

[0033] Example:

[0034] See also Figure 1 and 3 A soil sampling device for agricultural technology detection includes a bracket 1, a through hole 2 is opened at the bottom end of the bracket 1, and a support plate 3 is fixedly connected to the inner end of the bracket 1, an electric push rod 4 is installed on the support plate 3, and the output end of the electric push rod 4 is fixedly connected to a mounting plate 5, and a plurality of push rods 6 are fixedly connected to one end of the mounting plate 5, and a sampling component 7 is arranged on the inner side of the bracket 1.

[0035] The soil sampling link in agricultural technical testing refers to the collection of soil samples on agricultural land for soil quality testing. Soil sampling and testing usually involves sampling the soil layer by layer from top to bottom, and observing and testing the soil in each layer separately. The bracket 1 in this solution can be placed vertically or horizontally. The user can place the bracket 1 vertically above the soil to be sampled, and drill the soil through the sampling column 705 in the sampling component 7. After drilling, the user can flip the bracket 1 so that the bracket 1 is placed horizontally, and push out the soil bin 706 used to fill the soil in the sampling column 705 through multiple push rods 6. This arrangement allows the extracted soil to be pushed out completely, and the pushed out soil structure is not destroyed, retaining the layering, so that the user can observe the soil intuitively, and it is also convenient for the user to collect and preserve the soil.

[0036] See also Figure 1-4The sampling assembly 7 includes a servo motor 701 and a limit rod 703, both of which are fixedly connected to the bracket 1, and a reciprocating screw rod 702 is fixedly connected to the output end of the servo motor 701, and the reciprocating screw rod 702 is rotatably connected to the bracket 1 at one end away from the servo motor 701, and the sampling assembly 7 also includes a sampling column 705, and a scale line is engraved on one end of the sampling column 705, and a movable block 704 is fixedly connected to the end of the sampling column 705 away from the scale line, and the movable block 704 matches the reciprocating screw rod 702, and The movable block 704 is slidably connected to the limiting rod 703, and a rectangular groove and a plurality of limiting holes are respectively provided on the sampling column 705. The limiting block is connected to the rectangular groove, and a soil bin 706 matching the rectangular groove is slidably connected to the inner wall of the rectangular groove. A sliding rod 707 is slidably connected in the limiting hole. One end of the sliding rod 707 extends into the rectangular groove and is fixedly connected to the soil bin 706. A plurality of top rods 6 correspond one by one to a plurality of limiting holes. A spring is sleeved on the outer end of the sliding rod 707, and both ends of the spring are respectively fixedly connected to the sliding rod 707 and the inner wall of the limiting hole.

[0037] In this solution, when sampling the soil, the user can place the bracket 1 vertically above the soil to be sampled, and then start the servo motor 701 to drive the reciprocating screw 702 to rotate. The rotation of the reciprocating screw 702 drives the movable block 704 to move downward, and then drives the sampling column 705 to move downward. During the downward movement, the sampling column 705 drives the movable block 704 to slide on the limit rod 703, thereby ensuring the stability of the sampling column 705 during vertical movement. When the sampling column 705 passes through the through hole 2 and is inserted into the soil on the lower side of the bracket 1, the soil will be squeezed into the soil bin 706 in the sampling column 705. As the sampling column 705 extends into the soil, the soil will enter the inner cavity of the soil bin 706 from top to bottom in different layers and finally fill the soil bin 706. At this time, as the reciprocating screw 702 continues to rotate, the sampling column 705 will move upward to reset, and finally leave the soil and return to the inner side of the bracket 1.

[0038] After drilling, the user can flip the bracket 1 to place it horizontally so that the side of the sampling column 705 with the scale lines is facing up, and then the user starts the electric push rod 4 to advance in the direction close to the sampling column 705, thereby pushing the mounting plate 5 and multiple push rods 6 to move. Multiple push rods 6 abut against the sliding rod 707 and push the sliding rod 707 toward the inside of the limiting hole. The sliding rod 707 slides in the limiting hole and moves to the inside of the rectangular groove. While the sliding rod 707 moves, it squeezes the spring, and the sliding rod 707 pushes the soil bin 706 to slide in the rectangular groove and brings the soil bin 706 to the outside of the sampling column 705. At this time, the soil in the soil bin 706 is pushed out and displayed in front of the user. Since the soil is not squeezed during the pushing process, the soil retains a good layering. At the same time, by comparing the scale lines on the sampling column 705, the depth of each layer of soil in the soil bin 706 when it is located underground can also be more accurately judged.

[0039] Working principle:

[0040] When the user samples the soil, the bracket 1 needs to be placed vertically above the soil to be sampled, and then the servo motor 701 is started to drive the reciprocating screw 702 to rotate, and the reciprocating screw 702 drives the movable block 704 to move downward, thereby driving the sampling column 705 to move downward. When the sampling column 705 passes through the through hole 2 and is inserted into the soil on the lower side of the bracket 1, the soil will be squeezed into the soil bin 706 in the sampling column 705. As the sampling column 705 extends into the soil, the soil will enter the inner cavity of the soil bin 706 from top to bottom in different layers and finally fill the soil bin 706. As the reciprocating screw 702 continues to rotate, the sampling column 705 will move upward to reset, and finally leave the soil and return to the inner side of the bracket 1, and then The user can flip the bracket 1 to place it horizontally so that the side of the sampling column 705 with the scale lines faces upward, and then the user starts the electric push rod 4 to advance in the direction close to the sampling column 705, thereby pushing the mounting plate 5 and multiple push rods 6 to move. The multiple push rods 6 abut against the slide bar 707 and push the slide bar 707 toward the inside of the limiting hole. The slide bar 707 slides in the limiting hole and moves to the inside of the rectangular groove. The slide bar 707 squeezes the spring while moving. The slide bar 707 pushes the soil bin 706 to slide in the rectangular groove and brings the soil bin 706 to the outside of the sampling column 705. At this time, the soil in the soil bin 706 is pushed out and displayed in front of the user, and the user can observe, extract or sample soil at different levels.

[0041] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
