The first end of the pry bar 2 is used to be pressed by the operator during the pulling process of the soil drill 3, and the second end of the pry bar 2 is used to be fixedly connected to the top end of the soil drill 3 during the pulling process of the soil drill 3.
[0031] The soil drill auxiliary device provided in this embodiment uses the upper positioning groove 4 and the lower positioning groove 5 on the auxiliary frame 1 to radially limit the soil drill 3, so as to keep the soil drill 3 vertical during the drilling process, eliminating the need for the operator to hold the soil drill 3 by hand and avoiding injury to the hand when the soil drill 3 is struck. It is safe and practical. The pry bar 2 is set on the top of the auxiliary frame 1 during the pulling process of the soil drill 3. The second end of the pry bar 2 is fixedly connected to the top end of the soil drill 3 during the pulling process of the soil drill 3. During the pulling process of the soil drill 3, the operator presses the first end of the pry bar 2 and uses the lever principle to pull the soil drill 3 upward, which saves time and effort and labor.
[0032] As a preferred embodiment of this invention, when using it, first lift the soil drill auxiliary device provided in this embodiment to the designated sampling location, insert the soil drill 3 shallowly into the soil, then put the upper positioning groove 4 and lower positioning groove 5 on the auxiliary frame 1 onto the outside of the soil drill 3, and then, without holding the soil drill 3 by hand, the operator knocks the soil drill 3 into the soil. After the soil drill 3 is stable, the auxiliary frame 1 can be removed, and then the soil drill 3 can be knocked to the depth required for sampling. Then, the auxiliary frame 1 is placed on one side of the soil drill 3, the pry bar 2 is set on the top of the auxiliary frame 1, and the second end of the pry bar 2 is fixedly connected to the top end of the soil drill 3. Then, the operator presses the first end of the pry bar 2 and uses the lever principle to pull the soil drill 3 upward.
[0033] As a preferred embodiment of this invention, the soil drill auxiliary device provided in this embodiment also includes a binding strap 6. The binding strap 6 is used to bind and fix the second end of the pry bar 2 to the top end of the soil drill 3 during the pulling process of the soil drill 3. The structure is simple and easy to assemble and disassemble. It should be noted that the binding strap 6 can be, but is not limited to, using hemp rope or steel wire rope. In this embodiment, the binding strap 6 is made of hemp rope, which facilitates binding and unbinding operations.
[0034] As a preferred embodiment of this invention, the top of the auxiliary frame 1 is provided with a limiting groove 7, which can accommodate the pry bar 2 and radially limit the pry bar 2, effectively preventing the pry bar 2 from deviating and facilitating its use.
[0035] As a preferred embodiment of this invention, the auxiliary frame 1 gradually tapers from the bottom to the top, which can save on manufacturing materials and improve structural stability.
[0036] As a preferred embodiment of this invention, the bottom length of the auxiliary frame 1 is 65cm, the width is 35cm, the overall height of the auxiliary frame 1 is 90cm, the length of the inclined side of the auxiliary frame 1 is 85cm, and the opening width of the upper positioning groove 4 is 6cm, which facilitates use. It should be noted that this embodiment only provides a preferred size for the auxiliary frame 1. In actual application, the above dimensions can be adjusted adaptively according to the operator's actual height, the length of the soil drill 3, and other specific circumstances.
[0037] As a preferred embodiment of this example, the auxiliary frame 1 is a steel frame and the pry bar 2 is a steel pipe, which is convenient to manufacture and use, and convenient for long-term use. It should be noted that this example only provides the preferred materials for the auxiliary frame 1 and the pry bar 2. In actual applications, the auxiliary frame 1 or the pry bar 2 can be made of iron or other materials, depending on the existing production conditions.
[0038] As a preferred embodiment of this invention, the top, middle and bottom of the auxiliary frame 1 are welded together as one piece, which is firmly connected and convenient for long-term use.
[0039] As a preferred embodiment of this invention, a first baffle is bolted to the upper positioning groove 4 at the top of the auxiliary frame 1, and a second baffle is bolted to the lower positioning groove 5 at the bottom of the auxiliary frame 1. After the upper positioning groove 4 and the lower positioning groove 5 on the auxiliary frame 1 are placed on the outside of the soil drill 3, the first baffle and the second baffle are installed so as to cooperate with the upper positioning groove 4 and the lower positioning groove 5 on the auxiliary frame 1 to surround the soil drill 3 in all directions.
[0040] As a preferred embodiment of this example, the length of the pry bar 2 is 360cm, which is convenient and saves effort. It should be noted that this example only provides a preferred size for the pry bar 2. In actual applications, the above dimensions can be adjusted according to the operator's actual height, the length of the soil drill 3, and other specific circumstances.
[0041] As a preferred embodiment of this invention, the pry bar 2 includes several short bars 8, which can be sequentially spliced together to form the pry bar 2, facilitating assembly and disassembly, transportation, and use. In this embodiment, there are three short bars 8, each 120cm long. It should be noted that the 120cm length of the short bars 8 is designed to ignore the length of the nesting and splicing parts between the short bars 8. In practical applications, the short bars 8 need to reserve the length for nesting and splicing with adjacent short bars 8 to ensure that the length of the pry bar 2 after the three short bars 8 are spliced together can be 360cm.
[0042] As a preferred embodiment of this invention, any two adjacent short rods 8 are connected by threads, which provides a stable connection and facilitates use. It should be noted that this embodiment only provides a preferred connection structure for any two adjacent short rods 8. In practical applications, as an optional embodiment, any two adjacent short rods 8 can also adopt connection structures such as snap-fit connection or bolt connection.
[0043] Example 2

It is safe and practical. The pry bar 2 is set on the top of the auxiliary frame 1 during the pulling process of the soil drill 3. The second end of the pry bar 2 is fixedly connected to the top end of the soil drill 3 during the pulling process of the soil drill 3. During the pulling process of the soil drill 3, the operator presses the first end of the pry bar 2 and uses the lever principle to pull the soil drill 3 upward, which saves time and effort and labor.
[0046] In a preferred embodiment of this invention, the soil drill auxiliary device is first lifted to the designated sampling location, and the soil drill 3 is shallowly inserted into the soil. Then, the upper positioning groove 4 and lower positioning groove 5 on the auxiliary frame 1 are placed on the outside of the soil drill 3. Without holding the soil drill 3 by hand, the operator knocks the soil drill 3 into the soil. After the soil drill 3 is stable, the auxiliary frame 1 can be removed. The soil drill 3 is then knocked to the depth required for sampling. The auxiliary frame 1 is then placed on one side of the soil drill 3, and the pry bar 2 is placed on top of the auxiliary frame 1. The second end of the pry bar 2 is fixedly connected to the top of the soil drill 3. Then, the operator presses the first end of the pry bar 2 and uses the lever principle to pull the soil drill 3 upward.
[0047] It should be noted that in the soil sampling assembly provided in this embodiment, the soil drill 3 can be a conventional existing soil drill device. In practical applications, the specific dimensions of the auxiliary frame 1 can be adapted to the specific dimensions of the soil drill 3 to ensure that the auxiliary frame 1 and the soil drill 3 are compatible.
