Description

Technical Field

[0001] The invention belongs to the technical field of sampling equipment, and in particular relates to an ecological geological survey sampling device. Background Art

[0002] Ecological geological survey is an environmental geological survey and research work that serves ecological construction and protection. It specializes in investigating and studying the mutual influence between the geological environment and the survival and evolution of the biological world. Ecological geological surveys often involve soil sampling, and comprehensive analysis of the soil can reveal the soil conditions of the area.

[0003] In the prior art, soil sampling is usually performed using a sampling drill, which is convenient, labor-saving and quick. However, the sampling drill is inserted into the soil in a spiral descending manner. Since the surface soil is relatively loose, when drilling the surface soil, the upper soil will be disturbed as the sampling drill rotates, and the upper soil will move to the lower layer with the sampling drill, destroying the original hierarchical relationship of the soil and affecting the accuracy of sampling. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an ecological geological survey sampling device to solve the problem that when the existing sampling device is performing soil sampling, the rotation of the sampling drill will disturb the upper soil layer, and the upper soil layer will move to the lower layer with the sampling drill.

[0005] The present invention solves the above technical problems by the following technical means:

[0006] An ecological geological survey sampling device comprises a base plate and a support leg, wherein a circular hole is arranged in the middle of the base plate, an angle adjustment mechanism is arranged in the circular hole, a base is arranged at the bottom of the angle adjustment mechanism, a guide cylinder is fixedly connected to the base, a first strip opening and a second strip opening are symmetrically arranged on the wall of the guide cylinder, a sampling cylinder is movably arranged inside the guide cylinder, a through hole for the sampling cylinder to pass through is arranged on the base, a cylinder cap is arranged on the top of the sampling cylinder, a fixing plate is arranged on the top of the cylinder cap, a guide hole is arranged on the fixing plate, and a pulling rope is fixedly connected to the top of the guide plate; a one-way ratchet mechanism is arranged on the base, and the one-way ratchet mechanism comprises a shell A partition is provided inside the shell, which divides the shell into a first chamber and a second chamber. A ratchet is provided in the first chamber, and the rotating shaft of the ratchet extends to the second chamber. A check pawl and an active rocker are provided in the first chamber, and the active ratchet is provided on the active rocker; a steel chain is wound around the rotating shaft, a guide shaft is provided in the second chamber, and the guide shaft is connected to the shell bearing. An outlet is provided on the top of the shell, one end of the steel chain is fixedly connected to the rotating shaft, and the other end is guided by the guide shaft and extends from the outlet to the outside of the shell, and passes through the first strip opening, the guide hole, and the second strip opening of the guide cylinder in sequence, and is finally fixed on the base.

[0007] On the basis of the above technical solution, the present invention also makes the following improvements:

[0008] Furthermore, the outer circular side wall of the upper half of the sampling tube is provided with an external thread, and a cavity is provided in the base. The cavity is provided with a first gear, a second gear and a third gear meshing in sequence. The first gear and the second gear are connected to the base bearing through a shaft rod. The middle part of the third gear is provided with an internal thread matching the external thread. The internal thread hole of the third gear is aligned with the through hole of the base. The third gear is located in the cavity and rotates. The tube cap is rotatably connected to the top of the sampling tube, and the sampling tube can rotate along the axis. The shaft rod of the third gear extends to the outside of the top of the base. The end of the shaft rod is detachably connected with a cylindrical cam mechanism. The cylindrical cam mechanism can convert linear motion into rotational motion. The cylindrical cam mechanism is aligned with the active swing rod. The active swing rod can squeeze the cylindrical cam mechanism by swinging downward. The third gear can drive the sampling tube to rotate and move downward, thereby increasing the downward squeezing force, which is convenient for the sampling tube to be inserted into the lower soil.

[0009] Furthermore, the middle portion of the non-return pawl is rotatably connected to the side wall in the first chamber, and a clutch column is provided at the tail end of the non-return pawl, and the end of the clutch column extends to the outside of the shell, and the non-return pawl can be rotated by pressing the clutch column.

[0010] Furthermore, a handle is provided at the tail end of the active swing arm, and a rubber pad is provided on the handle.

[0011] Furthermore, an exhaust hole is provided on the tube cap to avoid vacuum phenomenon.

[0012] The beneficial effects of the present invention are as follows: the active swing arm is swung to drive the rotating shaft to rotate, so that the steel chain can be easily rolled up on the rotating shaft, and the sampling tube can be driven to slide downward along the guide tube under the squeezing of the rolled-up steel chain, thereby forcing the sampling tube to be vertically inserted into the soil, reducing the disturbance to the soil layer so as to obtain the original soil and ensure the vertical stratification of the soil.
