Technical Field

[0001] The utility model relates to the field of sampling equipment, in particular to a handheld soil extraction device. Background Technique

[0002] During the process of collecting soil by existing soil collection devices, most of them are unable to sample the soil in layers. As a result, during the process of extracting soil samples, it is impossible to relatively accurately grasp the conditions of the soil at different depths in the soil, and the gradual change of soil pollution is unknown. This leads to the need for multiple samplings during the sampling process to preliminarily judge the soil pollution situation, resulting in low sampling efficiency. Among them, a soil sample collection device with the application number "CN202221649901.X", the utility model is provided with a second motor. The bottom output end of the second motor is connected with a transmission shaft, and a cleaning blade is installed below the device box at the bottom end of the transmission shaft. Thus, it is convenient to clean the collection area with the cleaning blade before collecting soil, making the subsequent soil collection more convenient; through a plurality of collection grooves evenly arranged at different heights on the surface of the mounting plate, it is convenient to sample the soil at different depths, effectively reducing repetitive work and improving work efficiency. However, there are still certain deficiencies in the use of this device: due to the large volume and weight of this sample collection device, when sampling in complex terrain environments such as jungles or mountains, this device is not easy to carry and use, so its applicable range is limited to a certain extent.

[0022] Please refer to Figure 1 , Figure 2 , the sampling assembly 100 includes a handle 101, a connecting rod 102 is installed in the middle of the handle 101, a sampling cylinder 103 is installed at the bottom end of the connecting rod 102, a conical head 104 is installed at the bottom end of the sampling cylinder 103, and a spiral blade 105 is fixedly installed on the surface of the sampling cylinder 103.

[0023] During specific use: a connecting rod 102 is installed in the middle of the handle 101, and a sampling cylinder 103 is installed at the bottom end of the connecting rod 102. When sampling is required, hold the handle 101 so that the conical head 104 at the bottom end of the sampling cylinder 103 is inserted into the ground, and rotate the handle 101 so that the sampling cylinder 103 is driven to rotate through the connecting rod 102. The sampling cylinder 103 drills into the soil through the spiral blade 105 on the surface. During the drilling process, soil samples are collected through the sampling cylinder 103, and the spiral blade 105 conveys the excess soil upward, facilitating drilling. The device has a simple structure, small size, light weight and is convenient to carry, and is suitable for use in different sampling environments.

[0024] Please refer to Figure 2, the connecting component 200 includes a connecting ring 201 connected to the bottom end of the connecting rod 102. A connecting seat 202 is installed at the top of the sampling cylinder 103. Connecting holes 203 are correspondingly formed on the surfaces of the connecting ring 201 and the connecting seat 202, and a connecting bolt 204 is connected inside the connecting holes 203.

[0025] During specific use: the connecting ring 201 is installed at the bottom end of the connecting rod 102. Connecting holes 203 are correspondingly formed on the surface of the connecting seat 202 at the top of the sampling cylinder 103. The connecting bolt 204 is inserted into the connecting holes 203 to fix the connecting rod 102 and the sampling cylinder 103. After sampling, the connecting bolt 204 is unscrewed to facilitate the disassembly of the sampling cylinder 103 and the connecting rod 102, which is convenient for carrying.

[0026] Please refer to Figure 3 , an installation box 300 is installed in the middle of the handle 101. A limiting block 301 is rotatably installed inside the installation box 300. Tooth grooves 302 are formed on both sides of the surface of the limiting block 301. A gear 303 is installed at the top end of the connecting rod 102. The gear 303 is arranged inside the installation box 300 and meshed with one side of the tooth grooves 302. A lever 304 is installed at the bottom of the installation box 300. The lever 304 is fixedly connected to the limiting block 301. An installation cavity 305 is formed inside the installation box 300. A spring 306 is installed inside the installation cavity 305. One end of the spring 306 is connected to a limiting ball 307. Two limiting grooves 308 are formed on the back of the limiting block 301. The limiting ball 307 is inserted into the limiting grooves 308.

[0027] During specific use: An installation box 300 is installed in the middle of the handle 101. A limiting block 301 is rotatably installed inside the installation box 300. Tooth grooves 302 are formed on both sides of the surface of the limiting block 301. A gear 303 connected to the top of the connecting rod 102 is arranged in the installation box 300 and meshes with the tooth groove 302 on one side of the limiting block 301. By rotating the lever 304, the limiting block 301 is driven to rotate, so that the tooth groove 302 on one side of the adjusting limiting block 301 corresponds to and meshes with the gear 303. A limiting ball 307 is connected to the inside of the installation cavity 305 through a spring 306. The limiting ball 307 is inserted into one of the limiting grooves 308 formed on the back of the limiting block 301. When the lever 304 drives the limiting block 301 to rotate, the limiting block 301 pushes the limiting ball 307 to move towards the inner wall of the installation cavity 305. When the adjustment of the limiting block 301 is completed, the spring 306 pushes the limiting ball 307 to be inserted into the limiting groove 308, and the limiting block 301 is limited by the limiting ball 307. When the handle 101 drives the connecting rod 102 to rotate and drill, the gear 303 at the top of the connecting rod 102 can only rotate in one direction due to the limitation of the limiting block 301 inside the installation box 300. By reciprocally swinging the handle 101, the sampling cylinder 103 at the bottom of the connecting rod 102 can be continuously drilled. After drilling is completed, the lever 304 is toggled to rotate the limiting block 301 so that the tooth groove 302 on the other side meshes with the gear 303. At this time, the handle 101 drives the connecting rod 102 to rotate in the reverse direction, so that the sampling cylinder 103 is taken out upward.

[0028] Please refer to Figure 1 , Figure 4 , the connecting rod 102 is composed of a first support rod 1021 and a second support rod 1022. The second support rod 1022 is inserted inside the first support rod 1021. A locking sleeve 1023 is installed at the top of the first support rod 1021. Scale lines 400 are engraved on the surfaces of the first support rod 1021 and the second support rod 1022.

[0029] During specific use: The connecting rod 102 includes a second support rod 1022 sleeved inside the first support rod 1021. The second support rod 1022 is locked in the first support rod 1021 through the locking sleeve 1023 at the top of the first support rod 1021. The first support rod 1021 and the second support rod 1022 can be telescopically adjusted, which is convenient for sampling soil at different depths. The scale lines 400 engraved on the surfaces of the first support rod 1021 and the second support rod 1022 are convenient for knowing the drilling depth.

[0030] Please refer to Figure 1 , Figure 3 , the surface of the handle 101 is provided with anti-slip grooves 500.

[0031] During specific use: The anti-slip grooves 500 on the surface of the handle 101 can increase the friction with the hand, which is convenient for gripping the handle 101.

[0032] A connecting rod 102 is installed in the middle of the handle 101, and a sampling cylinder 103 is installed at the bottom end of the connecting rod 102. When sampling is required, hold the handle 101 so that the cone head 104 at the bottom end of the sampling cylinder 103 is inserted into the ground, and rotate the handle 101 to drive the sampling cylinder 103 to rotate through the connecting rod 102. The sampling cylinder 103 drills into the soil through the spiral blades 105 on the surface. During the drilling process, soil samples are collected through the sampling cylinder 103, and the spiral blades 105 convey the excess soil upward to facilitate drilling. The device has a simple structure, small volume, light weight and is convenient to carry, and is suitable for use in different sampling environments.
