Technical Field

[0001] The utility model relates to the field of sampler devices, in particular to a soil sampler. Background Art

[0002] Patent 201820422011.2 discloses a soil sampler for construction. This patent requires manual pressing of the sampling tube into the soil, and controls the depth of the sampling tube according to the scale value on the outer wall of the bottom of the sampling tube. Since the setting position of the scale value is far away from the human grip, when the person bends over to use the sampling device, the line of sight will observe the scale from top to bottom, making it impossible to accurately control the depth of the sampling tube screwed into the soil. In addition, some people with poor eyesight also affect the depth of the sampling tube screwed into the soil, which has an adverse effect on soil sampling.

[0003] Therefore, those skilled in the art urgently need to provide a soil sampler that can accurately control the depth of the sampling tube screwed into the soil and reduce the error caused by manually screwing the sampling tube into the soil. Utility Model Content

[0004] The utility model aims to provide a soil sampler which can accurately control the depth of a sampling tube screwed into the soil and reduce the error caused by artificially screwing the sampling tube into the soil.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] like Figure 1-2As shown, a soil sampler includes a sampling tube 1, an electric telescopic rod 2, a motor 4, a support plate 6, a top plate 3 and a pressure plate assembly 5, wherein the top of the support plate 6 is fixedly connected to two electric telescopic rods 2, the tops of the movable ends of the two electric telescopic rods 2 are fixedly connected to the two ends of the bottom of the top plate 3, the middle position of the bottom of the top plate 3 is fixedly connected to the motor 4, the output shaft of the motor 4 is fixedly connected to the top of the sampling tube 1, the sampling tube 1 is movably connected to the pressure plate assembly 5, the electric telescopic rod 2 is electrically connected to a PLC controller, and the PLC controller is installed on the top of the support plate 6;

[0022] Specifically, the initial position of this device is that the bottom of the sampling tube 1 is flush with the horizontal plane of the support plate 6. The electric telescopic rod 2 is controlled by the PLC controller to retract at the initial position. The retraction amount of the electric telescopic rod 2 is the depth of the sampling tube 1 screwed into the soil, thereby accurately controlling the soil sampling amount of the sampling tube 1.

[0023] The pressure plate assembly 5 includes a pressure plate 51, pillars 52, a ring 53 and a handle 54. The pressure plate 51 is located inside the sampling tube 1. A plurality of pillars 52 are fixedly connected to the top of the pressure plate 51. A through hole is opened at the top of the sampling tube 1. The pillars 52 pass through the through hole. The top of the pillars 52 is fixedly connected to the ring 53. The outer side of the ring 53 is fixedly connected to the handle 54.

[0024] Specifically, when the electric telescopic rod 2 is retracted in the initial position, the motor 4 is turned on, and the output shaft of the motor 4 drives the sampling tube 1 to rotate, so that the sampling tube 1 can be screwed into the soil for sampling; at the same time, the pressure plate 51 is pushed up by the soil. During the whole process, the length of the designed support 52 does not affect the extension and retraction of the electric telescopic rod 2; when the sampling is completed, the PLC controller controls the electric telescopic rod 2 to extend, so that the sampling tube 1 is moved out of the soil, and continues to extend to a certain height, and the collection box is placed on the support plate 6. The handle 54 on the outside of the ring 53 is pressed, so that the soil collected in the sampling tube 1 can be pushed out and dropped into the collection box.

[0025] The pressing plate 51 matches the inner diameter of the sampling tube 1 , so that the soil in the sampling tube can be pushed out by the pressing plate.

[0026] The length of the support 52 matches the height of the sampling tube 1 , and the length of the support 52 does not affect the extension and retraction of the electric telescopic rod 2 .

[0027] The inner diameter of the ring 53 is larger than the outer diameter of the output shaft of the motor 4 , so that the ring 53 and the output shaft of the motor do not affect each other's work.

[0028] A circular hole is opened in the middle of the support plate 6 and is located below the sampling tube 1 . The size of the circular hole is larger than the outer diameter of the sampling tube 1 so that the sampling tube can pass through the circular hole and enter the soil.

[0029] A plurality of pointed posts 7 are evenly arranged on the bottom of the support plate 6. The pointed posts 7 are inserted into the soil. The contact area between the support plate and the ground is increased. The insertion of the pointed posts 7 into the soil improves the stability of the device.

[0030] The use process of this utility model is as follows:

[0031] The initial position of the device is that the bottom of the sampling tube 1 is flush with the horizontal surface of the support plate 6. The electric telescopic rod 2 is controlled by the PLC controller to retract at the initial position. The retraction amount of the electric telescopic rod 2 is the depth of the sampling tube 1 screwed into the soil, thereby accurately controlling the soil sampling amount of the sampling tube 1;

[0032] When the electric telescopic rod 2 is retracted in the initial position, the motor 4 is turned on, and the output shaft of the motor 4 drives the sampling tube 1 to rotate, so that the sampling tube 1 can be screwed into the soil for sampling; at the same time, the pressure plate 51 is pushed up by the soil. During the whole process, the length of the designed support 52 does not affect the extension and retraction of the electric telescopic rod 2; when the sampling is completed, the PLC controller controls the electric telescopic rod 2 to extend, so that the sampling tube 1 is moved out of the soil, and continues to extend to a certain height, and the collection box is placed on the support plate 6. The handle 54 on the outside of the ring 53 is pressed, so that the soil collected in the sampling tube 1 can be pushed out and dropped into the collection box; when used next time, the device is reset to the initial position.
