[0002] Soil sampling refers to the method of collecting soil samples, including the layout and sampling techniques of the samples. The sampling of profile soil samples should be carried out after the profile observation and recording are completed. Before sampling, the profile should be repaired and cleaned, and the topmost loose soil should be removed. Then, samples should be taken from the central typical part layer by layer from top to bottom.
[0003] When the existing simple drilling equipment is used for soil sampling in a desert environment, the drill bit of the existing drilling equipment is mostly extended downward by mechanically applying gravity to the drill bit, which makes the equipment as a whole bulky. However, under normal circumstances, due to the influence of the drilling environment, it is necessary to manually press down the drill bit to facilitate flexible control and sampling operations. However, the simple use of automated mechanical downward pressure is not convenient for a single worker to carry, transport and operate. Utility Model Content

[0020] like Figure 1-3 As shown, a simple drilling device for soil sampling in a desert environment in this embodiment includes a bracket 1, a mounting frame 2 is fixedly connected to the bottom end of the bracket 1, a bottom frame 3 is sleeved on the end of the mounting frame 2, and a group of mounting seats are installed on the left and right sides of the upper surface of the mounting frame 2 and the left and right sides of the upper surface of the bottom frame 3, a spring rod 4 is installed on the left and right sides of the surface of the mounting frame 2 and the bottom frame 3 through the mounting seats, and a mounting table 5 is installed on the surface of the spring rod 4 through a shaft sleeve, and the two are movably sleeved and connected by means of the shaft sleeve, and the spring rod 4 is used to cooperate with the mounting frame 2 and the bottom frame 3 to movably support the mounting table 5. A through hole is provided on the surface of the mounting platform 5, and a motor 9 is fixedly connected to the upper surface of the mounting platform 5. The motor 9 needs to be a motor with forward and reverse control, and the output shaft of the motor 9 is inserted and penetrates the inside of the through hole provided on the surface of the mounting platform 5, and the motor 9 provides power for the operation of the drill bit 10. An extension shaft 6 is extended and installed on the rear surface of the mounting platform 5, and the extension shaft 6 forms an L-shaped structure. An adjustment frame 7 is installed on the surface of the mounting frame 2 and on the side opposite to the mounting platform 5. A through groove is provided on the surface of the adjusting frame 7 from top to bottom, and the end of the extension shaft 6 extends into the interior of the adjusting frame 7 and is limited by the through groove for use.
[0021] Furthermore, a sleeve shaft 13 is sleeved at the end of the output shaft of the motor 9, and a drill bit 10 is inserted into the bottom end of the sleeve shaft 13, and a bolt 14 is installed on the surface of the sleeve shaft 13 and the top of the drill bit 10 extending into the sleeve shaft 13 through a screw hole, that is, a part of the shaft rod at the top of the entire probe 10 is inserted into the sleeve shaft 13 to form a sleeve effect, which is beneficial for the sleeve shaft 13 and the bolt 14 to freely disassemble and assemble the drill bit 10, thereby facilitating the replacement of the drill bit 10.
[0022] Furthermore, a group of rollers are rotatably connected to one side surface of the base frame 3, and a support shaft 11 and a sight ring 12 are fixedly connected to the other side surface, and the sight ring 12 is in the same vertical line as the motor 9. The sight ring 12 is used to make it easier for staff to identify the position.
[0023] Furthermore, the caliber of the sight ring 12 is larger than the diameter of the drill bit 10, and the drill bit 10 and the sight ring 12 are on the same vertical line. The drill bit 10 and the sight ring 12 overlap vertically, which facilitates the workers to perform drilling work accurately.
[0024] Furthermore, the outer surface of the mounting frame 2 is rotatably connected with a pressure rod 8, which can be connected with the help of a universal joint so that the pressure rod 8 has better mobility, and the rear end surface of the pressure rod 8 fits the end surface of the extension shaft 6 and is on the outer side of the adjustment frame 7. Similar to the principle of a lever, the pressure rod 8 is combined into a lever to press down the mounting platform 5 with effort.
[0025] Furthermore, the support shaft 11 is located on the left and right sides of the bottom surface of the base frame 3, and the sight ring 12 is located in the middle of the support shafts 11 on the left and right sides. The sight ring 12 is used to aim at the predetermined drilling position on the ground to facilitate drilling and sampling work.
[0026] Furthermore, the sleeve of the mounting platform 5 is located at the rear side of the bottom surface, and the bottom end of the sleeve is connected to the spring top of the spring rod 4, that is, the sleeve and the spring top form a connection effect, so that the movement of the entire mounting platform 5 is affected by the extension shaft 6 while being affected by the spring elastic force of the spring rod 4.
[0027] The method of using this embodiment is: when using, please refer to Figure 1-3First, the staff needs to manually push the bracket 1 to the pre-surveyed sampling location. The entire drilling device is arranged vertically, and the bottom of the drill bit 10 is in contact with the ground. Affected by the ground support, the mounting table 5 moves upward, so that the spring is stretched, and the reaction force of the spring is downward, so that the sight ring 12 overlaps and aims at the predetermined sampling point. Then the staff manually starts the motor 9, and the output shaft of the motor 9 rotates, thereby driving the drill bit 10 installed at the end of the output shaft of the motor 9 to rotate, and the drill bit 10 penetrates through the inside of the sight ring 12 to drill into the ground. During the drilling process on the ground, the staff manually presses the pressure rod 8 downward, and controls the extension shaft 6 to move downward inside the adjustment frame 7 through the pressing of the pressure rod 8, thereby synchronously driving the two ends of the mounting frame 2 to move downward inside the two ends of the corresponding base frame 3, thereby controlling the position of the mounting platform 5 to move downward synchronously. At this time, in addition to the manual force of pressing down the mounting platform 5 with the help of the lever principle, the spring return torque of the spring rod 4 is downward, thereby saving manpower. With the help of the downward movement of the mounting platform 5, the drill bit 10 is driven to extend synchronously into the ground, thereby completing the predetermined drilling work for sampling. It should be noted that when the drill bit 10 rotates downward a certain distance, the spring of the entire spring rod 4 will be compressed, and the elastic force will be upward. Due to the interaction between the drill bit 10 and the soil, the elastic force does not affect the drill bit 10 from continuing to move downward. When the drill bit 10 reverses and needs to come out of the soil, the extension shaft 6 is lifted up, carrying the spring elastic force to move upward, thereby achieving the effect of saving manpower again. However, the spring resistance is relatively large in the final stage of the reversal of the drill bit 10, and a large torque needs to be applied to complete the removal of the drill bit 10 from the soil.
[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
