A collection component 2 for cleaning the sampling rod 106 is slidably arranged on the sampling component 1, and the collection component 2 automatically takes out the soil in the sampling rod 106, facilitating the collection by the staff.

[0020] The sampling assembly 1 includes a support frame 101. Two lifting frames 102 are slidably arranged on the support frame 101. The two lifting frames 102 are arranged mirror-symmetrically on the support frame 101. An installation block 103 is rotatably arranged on the lifting frame 102. A sampling motor 104 is arranged in the installation block 103. An electromagnet block 111 is arranged on the output shaft of the sampling motor 104. Two fixing frames 112 are arranged at the upper end of the support frame 101. A collection assembly 2 is slidably arranged in the fixing frames 112. A positioning plate 107 is slidably arranged on the fixing frames 112. When the two positioning plates 107 approach each other, the sampling motor 104 is fixed to prevent the sampling motor 104 from deflecting due to vibration during the process of driving the sampling rod 106 to work. A lengthening rod 105 is detachably arranged on the electromagnet block 111. During transportation, the position of the lengthening rod 105 may shift. Both the upper ends of the sampling rod 106 and the lengthening rod 105 are provided with a connection cavity 109 and threads. The lower end of the lengthening rod 105 is provided with a connection groove. When it is necessary to install the lengthening rod 105 or the sampling rod 106 on the sampling motor 104, the connection cavity 109 on the lengthening rod 105 or the sampling rod 106 is inserted into the electromagnet block 111, and the electromagnet block 111 is driven to work. The electromagnet block 111 fixes the lengthening rod 105 or the sampling rod 106. The sampling motor 104 is driven to rotate, and the sampling motor 104 drives the lengthening rod 105 and the sampling rod 106 to rotate. When it is necessary to install the lengthening rod 105 on the sampling rod 106 or another lengthening rod 105, the upper end of the sampling rod 106 is inserted into the connection groove, and the fixation is achieved by tightening the threads. The number of lengthening rods 105 is adjusted according to the depth of the sample to be taken, so as to adjust the depth of the sampling rod 106. A drill bit 108 is arranged at the lower end of the sampling rod 106 to improve the efficiency of the sampling rod 106 drilling into the soil. The lengthening rod 105 is hollow, and the lower end of the sampling rod 106 is hollow. The sampled soil enters the sampling rod 106 and the lengthening rod 105. A cover plate 110 is detachably arranged on the sampling rod 106. After the cover plate 110 is removed, the sample soil in the sampling rod 106 is taken out.

[0021] The collection component 2 includes a first sliding frame 201 slidably mounted on the fixed frame 112. A recovery frame 202 is arranged on the first sliding frame 201.

The second electromagnet blocks 208 are inserted into the cover plate 110. When the second electromagnet blocks 208 are driven, the second electromagnet blocks 208 fix the cover plate 110. When the sliding rod 203 is driven to slide on the recovery frame 202, the sliding rod 203 drives the second electromagnet blocks 208 to move, and the second electromagnet blocks 208 remove the cover plate 110 from the sampling rod 106. A second sliding frame 206 is slidably arranged at the lower end of the recovery frame 202. A scraper 207 is slidably arranged on the second sliding frame 206. After the scraper 207 is inserted into the sampling rod 106, the second sliding frame 206 is driven to slide in the recovery frame 202, and the second sliding frame 206 drives the scraper 207 to slide in the sampling rod 106 to push out the sample soil in the sampling rod 106. Sliding blocks 204 are slidably arranged on both sides of the recovery frame 202. Cleaning heads 205 are arranged on the sliding blocks 204. The cleaning heads 205 flush the outside of the sampling rod 106 to complete the cleaning of the sampling rod 106 and improve the long-term working efficiency of the device.

First, install the sampling rod 106 on the first electromagnet block 111, insert the first electromagnet block 111 into the connection cavity 109, and drive the first electromagnet block 111 to work. The first electromagnet block 111 adsorbs the connection cavity 109. First, fix the first electromagnet block 111 and the connection cavity 109. Then drive the sampling motor 104 to work. The sampling motor 104 drives the first electromagnet block 111 to rotate. The first electromagnet block 111 drives the sampling rod 106 to rotate. The sampling rod 106 drives the drill bit 108 to rotate. At the same time, drive the lifting frame 102 to slide on the support frame 101. The lifting frame 102 drives the sampling motor 104 and the sampling rod 106 to drill into the ground to sample the soil. When it is necessary to increase the sampling depth of the sampling rod 106, drill the sampling rod 106 into the soil, turn off the first electromagnet block 111, release the fixation between the first electromagnet block 111 and the sampling rod 106, drive the lifting frame 102 to reset. Then insert the connection groove at the lower end of the extension rod 105 onto the thread at the upper end of the sampling rod 106, and then rotate the extension rod 105. The connection groove of the extension rod 105 is tightened with the thread at the upper end of the sampling rod 106 to fix the extension rod 105 and the sampling rod 106. Drive the lifting frame 102 to move on the support frame 101. The lifting frame 102 drives the sampling motor 104 and the first electromagnet block 111 to be inserted into the connection cavity 109 at the upper end of the extension rod 105, and drive the first electromagnet block 111. The first electromagnet block 111 adsorbs the extension rod 105 to fix the first electromagnet block 111 and the extension rod 105. Multiple groups of extension rods 105 are provided. The multiple groups of extension rods 105 are connected by connection grooves and threads to adjust the depth of the sampling rod 106.

[0023] After sampling is completed, all the extension rods 105 are removed. The sampling rod 106 with the sample is fixed to the electromagnet block one 111. The mounting block 103 is driven to rotate on the lifting frame 102. The mounting block 103 drives the sampling rod 106 to rotate, so that the axis of the sampling rod 106 is aligned with the axis of the recovery frame 202.

The sampling motor 104 is driven to work. The sampling motor 104 drives the sampling rod 106 to rotate, so that the sampling rod 106 drives the cover plate 110 to align with the electromagnet block two 208. The sliding rod 203 is driven to slide on the recovery frame 202. The sliding rod 203 drives the electromagnet block two 208 to insert into the cover plate 110. The electromagnet block two 208 is driven to work. The electromagnet block two 208 is fixed to the cover plate 110. The sliding rod 203 is driven to reset. The sliding rod 203 and the electromagnet block two 208 remove the cover plate 110 from the sampling rod 106. The sampling motor 104 is driven to rotate. The sampling motor 104 drives the sampling rod 106 to rotate. The end of the sampling rod 106 provided with the cover plate 110 is aligned with the scraper 207. The scraper 207 is driven to slide in the sliding frame two 206. The scraper 207 inserts into the sampling rod 106. The sliding frame two 206 is driven to slide in the recovery frame 202. The sliding frame two 206 drives the scraper 207 to move. The scraper 207 pushes out the soil in the sampling rod 106, realizing the extraction of the sample. Subsequently, the sampling motor 104 is reversed, and the sliding rod 203 is driven to install the cover plate 110 back onto the sampling rod 106, and the sampling work continues.

[0024] When the sampling rod 106 needs to be cleaned, the sliding frame one 201 is reset. The sliding block 204 is driven to slide on the recovery frame 202. The recovery frame 202 drives the cleaning head 205 to move to the position where the sampling rod 106 needs to be cleaned. The cleaning head 205 is driven to work. The cleaning head 205 cleans the sampling rod 106. During the movement of the present utility model, in order to prevent the mounting block 103 and the lifting frame 102 from deflecting, the positioning plate 107 is driven to fit with the sampling motor 104. The positioning plate 107 fixes the sampling motor 104, realizing the fixation of the lifting frame 102 and the mounting block 103.
