Description

Technical Field

[0001] This utility model relates to a needle-plate type soil disturbance profile measuring device. Background Technology

[0002] Deep tillage, as an important method of conservation tillage, can improve soil structure, reduce soil strength, eliminate soil compaction, and loosen the soil without turning it over, thereby forming a loose and deep topsoil layer. This improves soil moisture infiltration, promotes crop root growth, and increases crop yield. Many scholars have studied the tillage quality of deep tillage. In these studies, soil looseness, specific resistance, and soil disturbance coefficient are key parameters for evaluating tillage effectiveness. Accurate acquisition of these parameters requires precise soil disturbance profile measurement, which in turn relies on a reliable soil disturbance profile measurement device.

[0003] Many scholars have measured soil disturbance profiles, typically using simple macroscopic soil disturbance profile measuring instruments made of wooden strips (these instruments are prone to loosening). Soil disturbance parameters from deep tillage were obtained in trench experiments. However, in field trials, the wooden strips are easily damaged by soil adhesion or mechanical impact, requiring frequent maintenance or replacement. Furthermore, the wooden strips are susceptible to expansion and deformation due to humidity, and are easily deformed by external forces (such as soil resistance and operational vibrations). They also decay easily after long-term use, indicating insufficient durability. Summary of the Invention

[0004] This invention provides a needle-plate type soil disturbance profile measuring device to solve the problems existing in the prior art.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A needle-plate type soil disturbance profile measuring device includes a reading panel, steel rods, and a frame. The reading panel is vertically mounted on the frame and can move horizontally in the X and Y directions on the frame. Several steel rods are arranged side by side on one side of the reading surface of the reading panel. A stepped surface is provided on the reading surface of the reading panel, and all the steel rods vertically penetrate the stepped surface.

[0007] Furthermore, the device is also equipped with a needle lifting plate, which is horizontally placed on one side of the reading surface in the reading panel, and all the steel rods pass through the needle lifting plate.

[0008] Furthermore, the top of the steel rod is provided with a cap, the diameter of which is larger than the diameter of the hole in the lifting pin plate.

[0009] Furthermore, the device is also provided with an X slide rail, a Y slide rail and a rectangular frame. The X slide rail is fixed on the frame, the rectangular frame is slidably connected to the X slide rail, the Y slide rail is fixed on the rectangular frame, and the reading panel is slidably connected to the Y slide rail.

[0010] Furthermore, a level is provided on the surface of the step.

[0011] This utility model has the following beneficial effects:

[0012] This invention is not easily damaged, requires no frequent maintenance, is easy to manufacture and use, has good durability, and provides good performance. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 This utility model discloses a needle-plate type soil disturbance profile measuring device, comprising a reading panel 1, a steel rod 2, and a frame 3. The reading panel 1 is vertically mounted on the frame 3 and can move horizontally in the X and Y directions on the frame 3. Numerical values ​​are marked on one end face of the reading panel 1, forming a reading surface. The range of these values ​​is -450 to 400 mm (measuring height), and the range can be marked according to actual needs. The numerical markings are located in the center of the reading panel 1. For better and more intuitive reading, a horizontal line can be drawn on one side of each scale. The numerical values ​​can be directly engraved on the reading panel 1 or printed on paper and then pasted onto the reading panel 1.

[0018] Several steel rods 2 are arranged side by side on one side of the reading surface of the reading panel 1. A stepped surface 11 is provided at the bottom of the reading surface of the reading panel 1, and all the steel rods 2 vertically penetrate the stepped surface 11. The steel rods 2 are fitted with a clearance fit with the stepped surface 11, and the steel rods 2 are in a free-falling state. A level 12 is also provided on the stepped surface 11.

[0019] To facilitate the lifting of all the steel rods 2 at once, the device is also equipped with a lifting plate 4. The lifting plate 4 is horizontally placed on one side of the reading surface in the reading panel 1, and all the steel rods 2 pass through the lifting plate 4. The steel rods 2 and the lifting plate 4 are fitted with a clearance fit.

[0020] A headstock 21 is provided at the top of the steel rod 2. The diameter of the headstock 21 is larger than the diameter of the hole in the lifting plate 4. With this structure, the lifting plate 4 can be moved up directly. After the lifting plate contacts the headstock 21, the lifting plate 4 can be moved up further to lift all the steel rods 2.

[0021] The head 21 can be formed by attaching a rubber sleeve to the steel rod 2, or it can be formed by directly thickening the top end of the steel rod 2.

[0022] To enable the reading panel 1 to move horizontally in the X and Y directions on the frame 3, the device is also equipped with an X slide rail 31, a Y slide rail 32 and a rectangular frame 33. The X slide rail 31 is fixed on the frame 3, the rectangular frame 33 is slidably connected to the X slide rail 31, the Y slide rail 32 is fixed on the rectangular frame 33, the Y slide rail 32 is perpendicular to the X slide rail 31, and the reading panel 1 is slidably connected to the Y slide rail 32.

[0023] After deep tillage, the device is placed horizontally along the direction of deep tillage to measure the upper contour of soil disturbance. The frame 3 is placed above the deep tillage furrow, and the center of the reading panel 1 is aligned with the furrow by moving the slide rails. The frame 3 is adjusted (by placing soil blocks or installing adjustable legs on the frame) to make the entire device level (observe the level using the level instrument 12). The lifting plate 4 is used to fully lift the steel rod, and the lifting grid is gently lowered so that the bottom of the steel rod rests on the surface of the deep tillage furrow.

[0024] A camera is used to take pictures of the reading panel directly. The photos are then imported into AutoCAD software. The positions of the steel rod vertices are drawn sequentially using the polyline command. The coordinates of the polyline points are then extracted using the LIST command in AutoCAD software. Combined with the panel scale, the upper profile of the soil disturbance can be obtained. After obtaining the upper profile of the soil disturbance, the disturbed soil is gently removed, and the profilometer is placed vertically on the trench to measure the lower profile of the soil disturbance.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
