Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling for soil detection, in particular to a soil sampling device for forest ecological soil detection. Background Art

[0002] Forestry pests and diseases will directly cause significant economic losses, and the damage to the ecological environment is even more inestimable. The spread of forestry pests and diseases is rapid, which will pose a huge threat to forest resources and natural landscapes. Therefore, it is necessary to monitor forestry pests in a timely and accurate manner.

[0003] The prior art discloses a soil sampling device for garden soil detection with the patent number CN107014638B, including a bottom plate and a vertical frame integrally formed on one side of the top of the bottom plate. One end of the bottom plate is provided with a pulley, and pedals are integrally formed on both sides of the bottom plate. A storage box is installed at the top of the bottom plate and away from the pulley. A kit is installed inside the top of the vertical frame. A screw rod is inserted through the inner side of the kit. The kit includes a threaded cylinder body. A transmission gear disc is integrally formed at the middle position outside the threaded cylinder body, and limiting rings are further provided at the top and bottom of the transmission gear disc. The limiting rings and the outside of the threaded cylinder body are of an integrally formed structure. A limiting snap ring is sleeved outside the limiting ring, and the limiting snap ring is fixed inside the vertical frame. The screw rod and the threaded cylinder body are of a threaded connection structure. A limiting sleeve is installed at the bottom on the right side of the top of the vertical frame, and the limiting sleeve is sleeved outside the screw rod. The bottom end of the screw rod is threadedly installed with a soil sampling cylinder body. A scale and a motor are respectively installed on the top of the vertical frame from left to right. The scale is located at a position close to the screw rod and is vertically arranged. However, since the scale of this device is located at a position close to the screw rod and is vertically arranged, the scale of this device can only be vertically arranged with the horizontal ground. When the device takes soil on an inclined ground, the scale changes from a vertical state to an inclined state. At this time, the staff can only judge the moving length of the soil sampling cylinder body after entering the soil layer through the scale, and cannot judge the horizontal moving length component and the vertical moving length component of the soil sampling cylinder body after entering the soil layer, that is, cannot judge the precise position of the soil sampling cylinder body in the soil layer. If the sampling position is not accurate enough, it may affect the subsequent soil detection work, and the use has limitations. Summary of the Utility Model

[0020] Embodiment

[0021] Please refer to Figures 1-3 As shown, in this embodiment, a soil sampling device for forestry ecological soil detection is provided. The measuring mechanism is arranged at one end of the top of the soil sampling device body 1. The measuring mechanism includes an angle indicating plate 21, a protractor 22, a damping rotating shaft 23, a through hole 24 and a level 25. The rear end of the angle indicating plate 21 is in sliding contact with the front end of the protractor 22, and the center of the rear end of the angle indicating plate 21 is movably connected to the center of the lower part of the protractor 22 through the damping rotating shaft 23. A through hole 24 is also formed in the middle of the protractor 22, and a level 25 is fixedly connected between the inner walls on both sides of the through hole 24.

[0022] Furthermore, the top end of the scale 3 installed on the soil sampling device body 1 is fixedly connected to the center of the bottom end of the angle indicating plate 21.

[0023] Furthermore, the angle indicating plate 21 is in the shape of a flat long strip, and the angle indicating plate 21 always remains perpendicular to the scale 3. The two ends of the angle indicating plate 21 are in the shape of sharp corners, and the two ends of the angle indicating plate 21 are symmetrically distributed with respect to the scale 3.

[0024] Furthermore, the protractor 22 is in a semi-circular shape, and the protractor 22 can rotate circumferentially around the damping rotating shaft 23.

[0025] Furthermore, the right-angle side of the protractor 22 always remains parallel to the level 25.

[0026] Furthermore, an air bubble is arranged in the level 25, and the position of the air bubble in the level 25 can be used to judge whether the right-angle side of the protractor 22 is horizontal.

[0027] Please refer to Figures 1-3As shown, in practice, the soil-taking device body 1 is used for soil-taking operations, and the measuring mechanism is used to measure the degree of inclination of the scale 3. When the soil-taking device body 1 is placed on the inclined ground 5 for soil-taking operations, the moving length of the soil-taking cylinder 4 installed on the soil-taking device body 1 after entering the soil layer is recorded as S. Since the moving directions of the scale 3 and the soil-taking cylinder 4 are parallel, S can be obtained through the scale reading of the scale 3. The horizontal moving length component of the soil-taking cylinder 4 after entering the soil layer is recorded as X, and the vertical moving length component of the soil-taking cylinder 4 after entering the soil layer is recorded as Y. First, let the right-angled side of the protractor 22 face downward, and let the protractor 22 rotate around the damping shaft 23 until the right-angled side of the protractor 22 remains horizontal. When the air in the level 25 When the bubble moves to the center of the level 25, it can be determined that the right-angled side of the protractor 22 remains horizontal. At this time, the angle indicator plate 21 will indicate a scale on the protractor 22. The scale is read and the angle value is recorded as Q. Finally, through the geometric relationship and trigonometric function relationship, it can be known that the inclination angle of the ruler 3 is also Q. The horizontal movement length component can also be obtained as: X = SsinQ, and the vertical movement length component is: Y = ScosQ. The precise position of the soil-taking cylinder 4 in the soil layer can be determined based on S and Q. It is worth mentioning that if the horizontal movement length component or the vertical movement length component is predetermined in advance, and Q is obtained in combination with the measuring mechanism, S can also be obtained in reverse through the geometric relationship and trigonometric function relationship. Overall, the device has a simple structure and is easy to use. When performing soil-taking operations on different inclined grounds 5, the precise position of the soil-taking cylinder 4 in the soil layer can be determined, which is beneficial to subsequent soil detection work.
