Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a mangrove wetland sampling device. Background Art

[0002] Due to the complex environment of mangrove wetlands and the densely intertwined root systems in the soil, traditional sampling tools often have difficulty penetrating these root systems, resulting in many difficulties in the sampling process. Sampling personnel often need to spend a lot of physical strength and time to barely obtain a small amount of soil samples, and the sampling depth is often limited, which cannot meet the requirements of scientific research or environmental monitoring for soil sample depth and representativeness.

[0003] And when encountering thick or dense root systems, traditional sampling tools are often blocked because they cannot cut through the roots, and even lead to sampling failure. This not only wastes time and resources, but may also cause unnecessary damage to the mangrove ecological environment. Therefore, there is an urgent need for a new type of equipment that can efficiently and smoothly penetrate the mangrove root system and achieve deep sampling, so a mangrove wetland sampling equipment is proposed.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-10The present invention provides a technical solution: a mangrove wetland sampling device, comprising a sampling barrel 1 with a rectangular cross section, wherein a sampling cavity 101 for collecting soil samples is arranged inside the sampling barrel 1, and a cutting assembly 2 for cutting mangrove roots in the soil is arranged on the sampling barrel 1, wherein the cutting assembly 2 comprises two blades 201 and two rotating plates 202, wherein the two blades 201 are respectively arranged at the lower ends of the front and rear side walls of the sampling barrel 1, and the middle parts of the two blades 201 are both rotatably connected to the side walls of the sampling barrel 1, and the two rotating plates 202 are respectively arranged at the upper ends of the front and rear side walls of the sampling barrel 1, and the middle parts of the two rotating plates 202 are both rotatably connected to the side walls of the sampling barrel 1; two connecting rods 203 are arranged between the blades 201 and the rotating plates 202 on the same side, wherein the blades 201, the rotating plates 202 and the two connecting rods 203 form a quadrilateral structure, and the ends of the connecting rods 203 are both rotatably connected to the blades 201 and the rotating plates 202;

[0031] Wherein, pedals 204 for driving the blade 201 and the rotating plate 202 to rotate are arranged on both sides of the upper end of the sampling tube 1 .

[0032] like Figure 1 , 5 As shown, in order to be able to drive the blade 201 on the cutting assembly 2 to rotate by stepping on the pedal 204, specifically, the cutting assembly 2 also includes a rotating shaft 205, and the rotating shaft 205 is rotatably connected to the upper end of the sampling tube 101, and the two pedals 204 are respectively fixedly connected to the two ends of the rotating shaft 205, and two large gears 206 are fixedly sleeved on the side wall of the rotating shaft 205, and small gears 207 are fixedly connected to the rotating shafts of the two rotating plates 202, and the two large gears 206 are correspondingly meshed with the small gears 207 on the same side.

[0033] Working process:

[0034] When using the mangrove wetland sampling device, the user first aligns the sampling tube 1 with the ground position where sampling is required. Then, the user steps on any pedal 204 with one foot to apply downward force to the sampling tube 1 so that it can be smoothly inserted into the ground. During the insertion process, if there is resistance to sliding downward, especially when encountering the root system of the mangrove, the user needs to continue to step on the pedal 204 downward and rotate the pedal 204 back and forth with the foot at the same time. At this time, the pedal 204 will rotate with the rotating shaft 205. The large gear 206 on the rotating shaft 205 will rotate accordingly, and through the meshing transmission with the small gear 207, drive the rotating plate 202 to rotate. The rotating plate 202 drives the blade 201 to perform dynamic cutting under the sampling tube 1 through the transmission action of the connecting rod 203. The rotation of the blade 201 can effectively cut off the encountered root system, thereby ensuring that the sampling tube 1 can continue to be smoothly inserted downward. Through this process, the user can successfully collect the required soil samples while avoiding the interference of the mangrove root system on the sampling process.

[0035] like Fig.10 As shown, in order to fix the pedal 204 on the rotating shaft 205, specifically, both ends of the rotating shaft 205 are fixedly connected with the plug-in shaft 7, the pedal 204 is sleeved on the plug-in shaft 7, a limiting groove 8 is provided on the side wall of the rotating shaft 205, one end of the pedal 204 is plugged into the inside of the limiting groove 8, and the end of the plug-in shaft 7 away from the rotating shaft 205 is connected with a nut 9 through threaded engagement;

[0036] When using the mangrove wetland sampling device, first ensure that the pedal 204 is correctly installed on the rotating shaft 205. The pedal 204 is sleeved on the plug-in shaft 7 and fastened at the end of the plug-in shaft 7 by the nut 9. At the same time, one end of the pedal 204 is inserted into the limiting groove 8 to ensure the stability and reliability of the pedal 204 when rotating.

[0037] like Figure 1 , 2 As shown in FIG9 , in order to cut off the roots on the left and right sides of the sampling tube 1 so as to facilitate the further downward insertion of the sampling tube 1, specifically, the left and right sides of the lower end of the sampling tube 1 are fixedly connected with guide plates 3, and the lower end surface of the guide plate 3 is a conical blade-like structure;

[0038] like Fig. 9As shown, line segment g represents the root system, point a is the intersection of the root system g and the guide plate 3, and the sampling tube 1 is aligned with the ground position where sampling is required. In the process of inserting the sampling tube 1 downward, the guide plate 3 at its lower end first contacts the soil and the root system. The lower end surface of the guide plate 3 is a conical blade-like structure with a certain cutting ability. For thinner roots, the lower end surface of the guide plate 3 can directly cut them off at the intersection a. If a thicker root system that is difficult to cut is encountered, the blade-like structure of the guide plate 3 will push the root system to one side at point a, so that the point a position of the root system gradually moves to the bottom of the blade 201.

[0039] At this time, the user continues to step down and rotate the pedal 204, and through the transmission of the rotating shaft 205, the large gear 206 and the small gear 207, the blade 201 is driven to perform dynamic cutting under the sampling tube 1. The rotation of the blade 201 can effectively cut the root system below it, including those roots that are supported to one side by the guide plate 3. In this way, the sampling tube 1 can continue to be inserted downward smoothly until the required sampling depth is reached. In the whole process, the synergistic effect of the guide plate 3 and the blade 201 ensures that the sampling tube 1 can successfully penetrate the root system of the mangrove and collect the required soil samples.

[0040] like Figure 7 and 8 As shown, in order to further improve the efficiency of root cutting, specifically, a rotation groove 102 for installing a blade 201 is opened on the side wall of the sampling tube 1, and both sides of the blade 201 are in an arc shape with the rotation axis of the blade 201 as the center, and both sides of the rotation groove 102 are adapted to the arc-shaped structure on both sides of the blade 201.

[0041] Specifically, the lower end surface of the blade 201 is in an arc shape, and both ends of the lower end surface of the blade 201 are provided with a “V”-shaped cutout 2011 .

[0042] like Figure 7 As shown, when the root system is supported by the guide plate to the bottom of the blade 201, the root system will be directly below the cutout 2011. At this time, when the blade 201 rotates (as shown in FIG. Figure 8 As shown in the figure, when the position of the incision 2011 moves downward, the incision 2011 cuts off the root system, thereby further improving the efficiency of cutting off the root system.

[0043] like Figure 1-4 As shown, when the sampling tube 1 is taken out from the ground, in order to prevent the soil in the sampling cavity 101 from falling out from the lower end, specifically, side cavities 103 are provided on both the left and right sides of the sampling tube 1, and a baffle 4 is provided inside the sampling cavity 101. A avoidance opening 401 is provided on the side wall of the baffle 4, and both ends of the baffle 4 extend into the corresponding side cavities 103 respectively;

[0044] Drawstrings 5 ​​are provided at both ends of the baffle plate 4 and inside the side cavity 103 . One end of the drawstring 5 away from the baffle plate 4 extends upward out of the side cavity 103 and is fixedly connected to a drawstring handle 6 .

[0045] like Figure 3 As shown, when the sampling tube 1 is inserted downward into the ground for sampling, the handle 6 on the right is pulled to cause the baffle 4 to slide toward the right side cavity 103. When the handle 6 on the left is against the inside of the left side cavity 103, the avoidance opening 401 is aligned with the sampling cavity 101. At this time, the soil can enter the interior of the sampling cavity 101 from the lower end of the sampling cavity 101. After the sampling tube 1 is inserted into a suitable position on the ground, the handle 6 on the left is pulled upward. At this time, the handle 6 on the left pulls the baffle 4 toward the left side cavity 103 through the pull rope 5. In this way, the avoidance opening 401 slides into the left side cavity 103. When the handle 6 on the right is against the mouth of the right side cavity 103, the baffle 4 blocks the bottom of the sampling cavity 101. In this state, when the sampling tube 1 is taken out from the bottom, the soil in the sampling cavity 101 can be prevented from falling out from the lower end.

[0046] Specifically, the baffle 4 is made of flexible aluminum alloy.

[0047] In addition, if Figure 5 As shown, in order to facilitate the removal of the soil collected in the sampling cavity 101, a rotating plate 104 is provided on one side of the sampling tube 1, and the side cavity 103 of the side is opened inside the rotating plate 104. The lower end of the rotating plate 104 is rotatably connected to the side wall of the sampling tube 1, and the upper end of the rotating plate 104 is fixed to the sampling tube 1 by bolts. When the bolts are loosened, the rotating plate 104 can be rotated to the position shown in FIG. Figure 5 In the state shown, one side of the sampling cavity 101 is opened, and the sampler 12 is inserted into the sampling cavity 101 horizontally, so that the soil in the sampling cavity 101 can be extracted, which is convenient and easy.

[0048] Specifically, the upper end of the sampling tube 1 is fixedly connected to a support rod 10 , the lower end of the support rod 10 can be engaged with the sampling tube 1 in the form of a thread, and the upper end of the support rod 10 is fixedly connected to a handle 11 .

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
