Description

Technical Field

[0001] This invention relates to the field of soil testing equipment technology, and more specifically to a device for rapid testing of soil at different depths. Background Technology

[0002] Crops cannot grow without soil. How to quickly and accurately detect soil fertility information is crucial to improving crop yield. Existing soil testing devices mainly collect data at specific depths during the soil testing process, which cannot provide a comprehensive understanding of soil information.

[0003] To address this, the present invention designs a rapid soil stratification detection device that can quickly detect soil at different depths during the drilling process. Furthermore, after the detection is completed, the soil in the drill pipe can be pushed back into the field, thus protecting soil resources. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid soil stratification detection device to solve the problems mentioned in the background art above.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rapid soil stratification detection device includes a stratification detection mechanism, a lifting mechanism, a variable amplitude mechanism, and a rotating mechanism. The stratification detection mechanism houses a detection probe connected to a near-infrared spectrometer. The probe passes through a hole in the upper end cover and a drill pipe drive shaft, and is positioned between an outer tube and an inner tube. The drill pipe drive shaft is a hollow shaft with a threaded hole at the bottom, and is bolted to the outer tube. The inner tube is a transparent acrylic tube. The outer tube has a spiral-shaped soil-cutting blade on its outer surface. The ends of the outer and inner tubes are threadedly connected to a drill bit, forming a drill pipe. A motor I and a hydraulic cylinder are mounted on the upper part of the stratification detection mechanism. Gear I is mounted on the output end of motor I, meshing with gear II mounted on the drill pipe drive shaft. A push rod is mounted on the piston end of the hydraulic cylinder. The drill pipe drive shaft is supported by drill pipe supports I and II and fixed to a connecting plate with bolts. The stratification detection mechanism is fixed to the lead screw seat of the lifting mechanism via the connecting plate.

[0007] Preferably, a motor II is installed above the lifting mechanism and fixed on a motor base, and the output end of motor II is connected to a lead screw through a coupling.

[0008] Preferably, the lifting mechanism is connected to the bracket of the luffing mechanism via a square tube bracket; the luffing mechanism is equipped with two position sensors, which are fixed on the sensor bracket.

[0009] Preferably, the amplitude-changing mechanism is welded to the slewing table of the slewing mechanism via a square tube support.

[0010] The soil stratification rapid detection device provided by the present invention, as described above, has the following beneficial effects:

[0011] 1. The detection probe of this invention is located between the outer tube and the inner tube, which can realize rapid detection of soil at different depths during the drilling process. At the same time, the detection probe does not come into contact with the soil during the detection process, thus improving its service life.

[0012] 2. The inner tube of this invention is equipped with a push rod, which can push the soil in the inner tube back to the field after the test is completed, thus protecting soil resources;

The stratification detection mechanism (1) houses a detection probe (102), which is connected to a near-infrared spectrometer (116). The probe passes through a hole in the upper end cover (107) and a drill drive shaft (113), and is positioned between the outer tube (115) and the inner tube (103). The near-infrared spectrometer (116) is mounted on the upper end cover (107). The drill drive shaft (113) is a hollow shaft with four threaded holes evenly distributed below, corresponding to the four threaded holes on the upper part of the outer tube (115) and connected by bolts.

The layer detection mechanism (1) is fixed to the screw seat (203) of the lifting mechanism (2) by the connecting plate (109).

[0026] like Figure 5 As shown, a motor II (204) is installed above the lifting mechanism (2) and fixed on the motor base (205). The output end of the motor II (204) is connected to the lead screw (202) through a coupling (206). The guide rail (210) is fixed on the square tube bracket (211). Bearing seats I (207) and II (201) are installed at the upper and lower ends of the guide rail (210). The motor base (205) is fixed on the bearing seat (207) by bolts. A lead screw nut seat (209) is installed on the lead screw (202). The lead screw nut seat (209) is installed on the lead screw seat (203). The lead screw seat (203) is fixed on the slider (208) by bolts. The slider (208) can slide up and down along the guide rail (210).

[0027] like Figure 1 and Figure 6As shown, the lifting mechanism (2) is connected to the bracket (304) of the luffing mechanism (3) via a square tube bracket (211); the luffing mechanism (3) is equipped with two position sensors (314), which are fixed on both sides of the sensor bracket (301). The sensor bracket (301) is a 90° arc and has a slot on it; the sensor bracket (301) is fixed to the bearing bracket (312) and the square tube support (311) by bolts; the bearing bracket (312) is equipped with two bearings (308) to support shaft I (302), and clamping brackets (303) are fixed at both ends of shaft I (302). There are four clamping brackets (303), all welded to the bracket (304). A sensing plate (313) is fixed to the left end of shaft I (302) to determine the current angle state of the amplitude-changing mechanism (3). The remaining two clamping brackets (303) clamp the end of shaft II (305). A fisheye connector (306) is fixed in the middle of shaft II (305). The end of the fisheye connector (306) is connected to the connecting rod II (307) by a thread. The connecting rod II (307) is connected to the connecting rod I (309) by a pin. The other end of the connecting rod I (309) is fixed to the left end of the power input shaft I (310).

[0028] like Figure 1 , Figure 7 and Figure 8 As shown, the variable amplitude mechanism (3) is welded to the rotary table (404) of the rotary mechanism (4) via a square tube support (311); the rotary table (404) is bolted to the cylindrical gear II (407), the cylindrical gear II (407) meshes with the cylindrical gear I (406), and the cylindrical gear I (406) is fixed on the power input shaft II (408); the outer surface of the cylindrical gear II (407) has grooves, which combine with the grooves on the inner surface of the outer ring (402) to form a ball channel; the outer ring (402) is bolted to the lower support (401), the lower support (401) is bolted to the lower end cover (409); the upper support (403) is bolted to the lower support (401), and the upper support (403) is bolted to the upper end cover (405).

Then the hydraulic cylinder (117) starts to work, so that the piston of the hydraulic cylinder (117) is at the top. Then the motor II (204) starts to work, driving the lead screw (202) to rotate, thereby causing the layer detection mechanism (1) to move downward in a straight line with the slider (208). When the drill bit (101) is about to contact the soil, the motor I (108) starts to work, driving the drill pipe to drive the rotating shaft. (113) Rotate, thereby driving the drill pipe to rotate and enter the soil; during the soil entry process, the near-infrared spectrometer (116) starts to work, the detection probe (102) emits near-infrared light and receives the reflected near-infrared light, after measuring the soil information within a certain depth range, motor I (108) stops working, motor II (204) reverses, causing the layer detection mechanism (1) to move upward in a straight line, at the same time, the hydraulic cylinder (117) starts to work, the piston of the hydraulic cylinder (117) drives the push rod (114) to move downward, discharging the soil in the inner tube (103); after the drill bit (101) of the layer detection mechanism (1) rises to a certain height above the ground, motor II (204) stops working.

[0030] When encountering complex terrain, power can be transmitted to the power input shaft II (408) to rotate the turntable (404) to a suitable angle, and then the above steps can be repeated to test the soil at a certain depth range.
