The invention is described in the following statement:
A Device Used to Take Samples of Desert Soil
Field of the Invention The present utility model relates to the technical field of soil sampling, specifically to a device used to take samples of desert soil.
Background of the Invention Desert soil, also known as "drought soil", is a kind of regional soil o developed in drought regions, which is also found covered by temperate desert vegetation. Crops growing in this kind of soil are drought-enduring. Specifically, this kind of soil includes grey desert soil, grey-brown desert soil, brown desert soil, etc. Desert soil is distributed in Africa, America, Australia and Central Asia, accounting for about one tenth of the world's continental area. In China, desert soil is mainly distributed in the northwestern regions including Xinjiang, Gansu, Qinghai and Ningxia. Currently, desert soil is mostly sampled by means of excavation and extraction. Extracted soil is often mixed without stratification. As a result, when detecting components in sampled soil, it is impossible to determine the depth of each component in the undisturbed stratum, and the o precision in detection is compromised. The patent with the authorization number of CN212363725U discloses a device used to take samples of desert soil. The above problems are well solved by providing a helical blade on the sampling drilling rod. However, in the technical solution of the patent, to pull out the sampling drilling rod at the end of sampling, two jacks are provided on the base. Due to limited lifting distance of the jack, it is difficult to completely pull the sampling drilling rod out and manual pulling is required; it is also difficult to ensure simultaneous jacking of the jacks, and the operation is quite troublesome.
Summary The present utility model aims to provide a device used to take samples of desert soil, which is easy to use and requiring no manual pulling when pulling out the sampling drilling rod, and thus reduces the labor intensity of the operator. The embodiments of the present utility model are realized through the following technical solution: A device used to take samples of desert soil, comprising a sampling syringe, with a base provided at the bottom of the sampling syringe; a support plate is o installed in the middle of the sampling syringe; a roller tube is connected between the support plate and the top wall of the sampling syringe; a lifting screw is threaded to the inside of the roller tube; a sampling drilling rod is connected to the bottom of the lifting screw; a helical blade is installed on the side wall of the sampling drilling rod; a bevel gear is installed at the center of the roller tube; a drive rod is screwed into the side wall of the sampling syringe; a bevel pinion is engaged with the bevel gear at the inner end of the drive rod; a motor is connected to the outer end of the drive rod; a battery pack is installed on the side wall of the sampling syringe; a battery supplying power to the motor is provided inside the battery pack; a spur gear is installed at the upper end of the roller tube; a rack is installed on one side of the spur gear, engaged with the spur gear; an inserted link is connected to the side of the rack far away from the spur gear; the inserted link slides into or out of the side wall of the sampling syringe; a spring is pressed between the inner wall of the sampling syringe and the rack; the spring is arranged on the inserted link; a turn plate is provided at the top of the lifting screw; a ring plate is connected to the turn plate, which can be disassembled; a guide rod is installed on both sides of the lifting screw; the guide rod is threaded onto the top of the sampling syringe; and the ring plate slides into or out of the guide rod. Preferably, several positioning holes are arranged circumferentially on the outer edge of the turn plate; and a registration mast is mounted on the inner edge of the ring plate on opposite sides to fit the positioning hole. Preferably, a stop dog is provided at the outer end of the inserted link; and a pull ring is installed on the stop dog. A limited post is provided on the side of the stop dog close to the sampling syringe; and a spacing hole is provided on the side of the sampling syringe to fit the limited post. Preferably, the lifting screw is connected to the sampling drilling rod with a flange. Preferably, several pins are provided at the bottom of the base. Preferably, the bottom of the sampling drilling rod is a conical structure. The present utility model at least has the following advantages and beneficial effects: in the present utility model, the ring plate and the guide rod are removed when running the sampling drilling rod into the soil to take samples. The roller tube cannot rotate because the spur gear on the roller tube is engaged with the rack; in this case, the turn plate is screwed to easily drive the sampling drilling rod downwards to take samples; after sampling, the guide rod and the ring plate are re-installed, and the inserted link is pulled to disengage the rack from the spur gear; with the motor started, the bevel gear and the bevel pinion drive the roller tube to rotate. As the lifting screw is threaded onto the roller tube, the roller tube, when rolling, pushes the lifting screw to move upwards with the constraint of the guide rod. Accordingly, the sampling drilling rod is pulled out of the soil without manual force by the operator, and thus the labor intensity of the operator is reduced.

Detailed Description of the Preferred Embodiments As shown in Fig. 1-3, a device used to take samples of desert soil, comprising the sampling syringe 1; the base 2 is provided at the bottom of the sampling syringe 1. It is easily understood that the diameter of the base 2 is much larger than that of the sampling syringe 1 to ensure high support stability. Several pins 23 are provided at the bottom of the base 2. The pin 23 can be inserted into the soil 25 to prevent displacement of the device in use. The support plate 3 is installed in the middle of the sampling syringe 1. The roller tube 4 is connected between the support plate 3 and the top wall of the sampling syringe 1. Rolling connection is realized by using a bearing to ensure smooth rotation of the roller tube 4. The lifting screw 5 is threaded to the inside of the roller tube 4. The sampling drilling rod 6 is connected to the bottom of the lifting screw 5. Specifically, the lifting screw 5 is connected to the sampling drilling rod 6 with the flange 22. The flange 22 is used to prevent the contact between the sampled soil 25 and the lifting screw 5, so as to avoid rough movement of the lifting screw 5 contaminated by the soil 25. The helical blade 7 is installed on the side wall of the sampling drilling rod 6. As in prior art, the helical blade 7 stratifies the sampled soil 25. The bottom of the sampling drilling rod is a conical structure which facilitates sinking of the sampling drilling rod 6.
The bevel gear 8 is installed at the center of the roller tube 4. The drive rod
10 is screwed into the side wall of the sampling syringe 1. The bevel pinion 9 is
engaged with the bevel gear 8 at the inner end of the drive rod 10. The motor 11
is connected to the outer end of the drive rod 10. The battery pack 12 is installed
on the side wall of the sampling syringe 1. The battery pack 12 can be welded to
the side wall of the sampling syringe 1. The battery supplying power to the
motor 11 is provided inside the battery pack 12. The output rotation speed of the
motor 11 is reduced through the bevel gear 8 and the bevel pinion 9 and acts on
the roller tube 4, and drives the roller tube 4 to rotate.
The spur gear 13 is installed at the upper end of the roller tube 4. The rack
14 is installed on one side of the spur gear 13, engaged with the spur gear 13.
The inserted link 15 is connected to the side of the rack 14 far away from the
spur gear 13. The inserted link 15 slides into or out of the side wall of the
sampling syringe 1. The spring 24 is pressed between the inner wall of the
sampling syringe 1 and the rack 14. The spring 24 is arranged on the inserted
link 15. The stop dog 16 is provided at the outer end of the inserted link 15. The
pull ring 17 is installed on the stop dog 16 to pull the inserted link 15 and drive
the rack 14 away from the spur gear 13.
In this embodiment, the limited post 18 is provided on the side of the stop
dog 16 close to the sampling syringe 1. The spacing hole is provided on the side of the sampling syringe 1 to fit the limited post 18. It shall be noted that, when the rack 14 and the spur gear 13 are engaged, the limited post 18 fits the spacing hole. When the inserted link 15 is pulled to disengage the rack 14 from the spur gear 13, the inserted link is rotated so that the end face of the limited post 18 is pressed against the side wall of the sampling syringe, so as to avoid the rebound of the rack 14 under the action of the spring 24. In this way, the operator no longer needs to use the hands to pull the inserted link 15 all the time when rotating the roller tube 4, providing convenience for use. The turn plate 19 is installed on the top of the lifting screw 5. The ring plate o 20 is connected to the turn plate 19. Specifically, several positioning holes 191 are arranged circumferentially on the outer edge of the turn plate 19; and the registration mast 201 is mounted on the inner edge of the ring plate 20 on opposite sides to fit the positioning hole 191. With this layout, it is easy and fast to assemble and disassemble the ring plate 20 and the turn plate 19. The guide rod 21 is installed on both sides of the lifting screw 5; the guide rod 21 is threaded onto the top of the sampling syringe 1, that is, the top of the sampling syringe 1 with a threaded hole connecting the guide rod 21, and the ring plate 20 slides into or out of the guide rod 21. The method for use of the present utility model is as follows: before sampling, as in prior art, a sampling hole is formed with a drilling device, and proper amount of water is injected into the sampling hole for wetting; in sampling, the guide rod 21 and the ring plate 20 are first removed, so that the rack 14 and the spur gear 13 are engaged to prevent rotation of the roller tube 4; the turn plate 19 is screwed to raise the lifting screw 5 to its limit position; the pin 23 is inserted into the sampling position and the base 2 and the soil 25 are closely attached to form a stable support. In this case, the turn plate 19 is screwed to sink the sampling drilling rod 6 for sample taking. After sampling is completed, the guide rod 21 and the ring plate 20 are re-installed. It shall be noted that, when the ring plate 20 and the guide rod 21 are re-installed, the guide rod 21 is inserted into the ring plate 20, and the guide rod 21 is aligned to the threaded hole in the sampling syringe for connection; then, the registration mast 201 on the ring plate 20 is fit with the nearest spacing hole 191 in the turning plate 19. In this case, if the guide rod 21 is not aligned to the threaded hole for connection, the turn plate 19 can be rotated as necessary to align the guide rod 21 to the threaded hole for connection. With alignment performed, the guide rod 21 is connected to and fixed in the threaded hole; in the following step, the inserted link 15 is pulled to disengage the rack 14 from the spur gear 14. The inserted link 15 is rotated to press the end face of the o limited post 18 against the sampling syringe 1, then the operator can relax the hold. with the motor 11 started, the bevel gear 8 and the bevel pinion 9 drive the roller tube 4 to rotate. As the lifting screw 5 is threaded onto the roller tube 4, the roller tube 4, when rolling, pushes the lifting screw 5 to move upwards with the constraint of the guide rod 21. Accordingly, the sampling drilling rod 6 is pulled out of the soil 25 without manual force by the operator, and thus the labor intensity of the operator is reduced. The above embodiment is just a preferable embodiment of the present utility model, which does not restrict the present utility model, and for those of skill in the art, the present utility model can be varied and changed. Any modifications, equivalent replacements, improvements, etc. under the spirit and principle of the present utility model shall be included and protected by the present utility model.
