When the rotary cylinder 10 needs to be detached, the user only needs to press the spring ball to withdraw the ball of the spring ball from the positioning hole, and the locking between the rotary cylinder 10 and the dual-joint rotary head 50 is released. When the rotary cylinder 10 is assembled with the double-joint rotary head 50, the upper end of the cylinder body 13 firstly extends into the positioning groove 53, the balls of the spring balls move to be in contact with the groove wall of the positioning groove 53, the balls are extruded and contracted by the groove wall of the positioning groove 53 along with the penetration of the cylinder body 13, and when the balls move to the positioning hole, the balls are embedded into the positioning hole under the action of the elastic force of the spring, so that the locking of the cylinder body 13 and the double-joint rotary head 50 is realized through the matching of the balls and the hole wall of the positioning hole.

The second connecting portion 52 includes a plurality of first limiting teeth 521, a limiting cavity (not shown in the figure) is formed between two adjacent first limiting teeth 521, and the fourth connecting portion 311 includes a plurality of second limiting teeth 3111 corresponding to the limiting cavity, as shown in fig. 3, when the second limiting teeth 3111 are located in the limiting cavity, the second limiting teeth 3111 are engaged with the first limiting teeth 521, and the rotary dual joint rotary head 50 can drive the second limiting teeth 3111 to rotate through the first limiting teeth 521, so as to rotate the screw 31. After the second spacing tooth 3111 withdraws from the spacing cavity, the second spacing tooth 3111 separates from the first spacing tooth 521, and the dual-joint rotating head 50 rotates, so that the screw 31 cannot rotate.

Further, in order to facilitate stable engagement between the second limiting tooth 3111 and the first limiting tooth 521, as shown in fig. 2 and fig. 3, a stopping portion 312 is disposed at an end portion of an upper end of the screw 31, the stopping portion 312 is located in the second hole section 55, a diameter of the stopping portion 312 is larger than a diameter of the first hole section 54 and smaller than a diameter of the second hole section 55, and a limiting table 56 is formed at a boundary of the first hole section 54 and the second hole section 55.

It should be noted that when the fourth connecting portion 311 is engaged with the second connecting portion 52, the upper end of the cylinder 13 exits the positioning groove 53.

In order to ensure that the material cup 20 has a large stroke in the cylinder 13, as shown in fig. 4, a groove 141 is formed at one end of the drill 14 connected to the cylinder 13, a lower end of the screw 31 extends into the groove 141, a bearing 142 is sleeved outside the screw 31, and the screw 31 and the drill 14 are rotatably matched through the bearing 142. Since the lower end of the screw 31 is protruded into the groove 141, the cup 20 can be moved toward the end of the lower end of the cylinder 13 as much as possible when the cup 20 is moved downward in the cylinder 13.

Further, as shown in fig. 4, a sealing ring 143 is provided at an opening end of the groove 141 to seal the bearing. Optionally, the sealing ring 143 is a teflon sealing ring, which has good lubricating property and wear resistance.

Further, in order to facilitate the axial support of the screw 31, a rotating ball 144 is disposed between the lower end of the screw 31 and the bottom of the groove 141.

As shown in fig. 5, a notch 21 is formed at the bottom of the cup 20, the notch 21 is blocked by an insert plate 22, and the insert plate 22 is detachably connected with the cup 20. When the material cup 20 moves to the discharging position, the gap 21 corresponds to the discharging port 12, and the inserting plate 22 is pulled away, so that the collected sand sample has better fluidity, and the sand sample can flow out of the cylinder 13 through the gap 21 and the discharging port 12 by virtue of the flowing characteristic of the sand sample per se through the gap 21 and the discharging port 12 to be collected by a collecting device (not shown in the figure). This kind of design can realize not taking out the collection that realizes husky appearance under the condition of material cup 20, has improved sample efficiency. It should be noted that, when the inserting plate 22 opens the gap 21, in order to prevent the sand sample from falling into the barrel 13 from the gap between the cup 20 and the barrel 13, a part of the inserting plate 22 may be overlapped on the bottom of the cup 20, that is, a part of the inserting plate 22 is inserted into the gap 21, and the sand sample can flow into the collecting device through the gap 21, the inserting plate 22 and the discharge hole 12.

After the sediment (i.e. sand sample) of the internal sand bag is taken out at certain intervals, one sample is taken out each time, and the rose willow leaves contained in the internal sand bag are carefully picked out by using tweezers on site or after being taken back to a laboratory. The leaves of the salix integra with different depths are selected for AMS carbon for 14 years, so that the specific age of the salix integra sand bag formation and development can be known. As the granularity change of the deposited sand from top to bottom in the sand bag section can reflect the evolution process of regional material sources and the wind sand environment, the obtained deposited sand is subjected to granularity characteristic analysis on a laser granularity meter. Wherein changes in the fine particle fraction of <10 μm record changes in the source, and changes in the coarse particle fraction >100 μm record changes in regional sand blast activity intensity. For the selected rose willow leaves, the isotope mass spectrometer can be used for analyzing the change of the content of the organic carbon isotope delta 13C, and the index is related to the regional moisture condition. The low delta 13C content indicates that the profile rose willow is in a humid environment during the deposition period, the carbon dioxide concentration and the temperature in the atmosphere are increased, and the value is larger. According to the deposited sand size characteristics of the salix mongolica sand bag and the change of the content of the organic carbon isotope delta 13C of the salix mongolica leaves buried at different depths, and the formation ages of different salix mongolica layers, the environmental change information stored in the salix mongolica sand bag can be extracted.
