[0002] A land quadrat is a specific area of ​​land set up in various fields such as land surveys and ecological research to obtain representative land-related information. It is a sampling survey method. Through detailed study of these quadrats, the land conditions of the entire study area can be inferred. Usually, it is also necessary to collect land samples. A soil drill can be used to drill holes at selected locations within the quadrat to collect samples. According to predetermined depth intervals, the soil extracted by the soil drill is collected in layers into different sample bags.

[0003] In existing grassland surveys, sampling is mostly done by using measuring tapes or stakes to define the area. Flexible parts not only have the risk of falling off and deforming, but are also troublesome to store or lay. Furthermore, soil sampling is also troublesome, as it is difficult to visually list and observe patterns at different vertical heights, and the soil needs to be repeatedly filled.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A quadrat sampling tool for grassland survey includes a quadrat ruler 1 and a central plate 5. Both sides of the quadrat ruler 1 are provided with connecting holes. A hollow pin 2 is rotatably connected to the inner side of the quadrat ruler 1. A connecting pin 3 is threaded to the bottom of the hollow pin 2. A piercing cone 4 is provided at the bottom of the connecting pin 3. The piercing cone 4 and the connecting pin 3 are integrally formed. A sampling cylinder 6 is provided on the inner side of the central plate 5.

[0027] The middle plate 5 includes a chassis 501, an extension frame 502 is bolted to the top of the chassis 501, a top plate 503 is bolted to the top of the extension frame 502, a diagonal frame 504 is rotatably connected to the top of the chassis 501, a plug rod 505 is provided on the inner side of the diagonal frame 504, and the inner side of the top plate 503 is movably connected to the sampling cylinder 6.

[0028] In this embodiment: By setting up a sample square ruler 1, when in use, according to the required frame size, a corresponding number of sample square rulers 1 are selected to form a rectangle. Hollow pins 2 are inserted into the inner side of the sample square ruler 1, and the connecting pins 3 are screwed into the inner side of the hollow pins 2 to complete the installation between the sample square rulers 1. At the same time, the piercing cone 4 is connected, and during operation, the piercing cone 4 is inserted into the ground to complete the frame of the rectangular sample square position. The middle plate 5, through the extension frame 502 and the top plate 503, can easily fix the position of the sampling tube 6, so that it is located in the center of the rectangular sample square position. When in use, the base plate 501 is inserted into the inner side of the diagonal hollow pin 2 through the insertion rod 505 at the bottom of the diagonal frame 504 to complete the installation of the structure, and can also limit the shape of the rectangular sample square formed by the sample square ruler 1.

[0029] Specifically, such as Figure 2 As shown, the sampling tube 6 includes a square tube 601, and an integrally formed partition 602 is provided in the middle of the inner wall of the square tube 601. A blade 603 is provided on the left side of the bottom of the partition 602.

[0030] Specifically, such as Figure 2 As shown, a separator 604 is bolted to the left side of the square tube 601. The inner side of the separator 604 is filled with viscous oil. A piston 605 is slidably connected to the inner side of the separator 604. A force-bearing rod 606 is bolted to the top of the piston 605.

[0031] Specifically, such as Figure 2 As shown, a rubber stopper 607 is provided on the left side of the blade 603, and the outer side of the rubber stopper 607 is in close contact with the isolation plate 604.

[0032] In this embodiment: by setting up a sampling cylinder 6, when in use, squeezing or hammering the sampling cylinder 6 from the top down can insert it into the soil. The soil will be placed vertically on the right side of the partition 602 of the square cylinder 601. Then, pressing down the force rod 606 pushes the internal viscous oil through the piston 605, causing it to push the blade 603 to cut the soil through the rubber stopper 607. Then, the sampling cylinder 6 is pulled out, and the soil on the right side of the partition 602 of the square cylinder 601 can be discharged at once. It also allows personnel to visually observe soil samples at different vertical heights.

[0033] Specifically, such as Figure 5 As shown, a sliding sleeve 7 is bolted to the inner side of the top plate 503, and the inner side of the sliding sleeve 7 is slidably connected to the sampling cylinder 6.

[0034] Specifically, such as Figure 2 As shown, a pusher 8 is slidably connected to the right side of the inner wall of the square tube 601, a paddle 9 is bolted to the right side of the pusher 8, and a hammer block 10 is bolted to the top of the square tube 601.

[0035] In this embodiment: by setting the sliding sleeve 7, the movement of the sampling cylinder 6 can be limited, and it can be limited to a vertical movement position. The push plate 8 and the paddle plate 9 can facilitate the pushing out of the pattern stored inside the square cylinder 601. The set hammer block 10 can facilitate the presence of a hammer, pressure device or manual pressing position at the top of the structure, so as to facilitate the pulling action.

[0036] Specifically, such as Figure 2 As shown, a contact frame 11 is bolted to the inner wall of the isolation plate 604, and a limit spring 12 is bolted to the top of the contact frame 11. The top of the limit spring 12 is in contact with the piston 605.

[0037] Specifically, such as Figure 4 As shown, the diagonal bracket 504 is rotatably connected to the chassis 501 on the side closest to the chassis 501 via a pivot. The diagonal bracket 504 has through slots on the middle of its inner side and on the side furthest from the chassis 501, and the insert rod 505 is rotatably connected to the inner side of the through slot.

[0038] In this embodiment: by setting the contact frame 11 in conjunction with the limiting spring 12, it is convenient to deform and store force when the piston 605 is pressed down, and to rebound and reset the piston 605 and the rubber plug 607 when the force is stopped. The through groove and multiple insert rods 505 can be used to facilitate the use of rectangular areas formed by different numbers of sample rulers 1.

[0039] Working principle: When sampling quadrats, according to the required frame size, select the appropriate number of quadrats 1 to form a rectangle. Hollow pins 2 are inserted into the inside of quadrats 1, and connecting pins 3 are screwed into the inside of hollow pins 2 to complete the installation of quadrats 1. As needed, piercing cones 4 are inserted into the ground to frame the position of the quadrat rectangle. The base 501 is inserted into the inside of the diagonal hollow pins 2 through the insertion rods 505 at the bottom of the diagonal frame 504 to complete the installation of the structure. At the same time, the rectangular quadrat shape formed by the quadrats 1 is defined. Force is applied vertically downward to the sampling cylinder 6 until it is inserted into the soil. The soil will be placed vertically on the right side of the partition 602 of the square cylinder 601. Then, the force rod 606 is pressed down, and the piston 605 pushes the internal viscous oil through the rubber stopper 607 to push the blade 603 to cut the soil. Then, the sampling cylinder 6 is pulled out, and the pusher 8 is pushed by the lever 9 to push the soil on the right side of the partition 602 of the square cylinder 601 to be discharged at one time.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
