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.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a soil sampling device for farmland improvement: a soil sampling device for farmland improvement, including a sampler 1 for collecting soil samples, the sampler 1 including:

[0027] The main component 11 includes an inner rod 112 that is slidably installed through the upper end of the outer rod 111, handles 113 installed on both sides of the upper end of the inner rod 112, and a fixing frame 118 fixed to the lower outer wall of the outer rod 111.

[0028] The mounting assembly 12 includes a mounting base 121 mounted on the lower end of the outer rod 111, three circumferentially distributed balls 122 movably mounted inside the outer wall of the mounting base 121, a guide rod 123 slidably mounted through the lower end of the mounting base 121, a guide sleeve 124 fixed to the outer wall of the lower end of the guide rod 123, and a spring 125 sleeved on the guide rod 123.

[0029] The sampling assembly 13 includes a sampling head 131 mounted on a mounting base 121, and three circumferentially distributed mounting holes 132 on the sampling head 131 that cooperate with the ball bearings 122.

[0030] In this embodiment, after the sampling head 131 is fitted onto the mounting base 121, the spring 125 pushes the guide sleeve 124 to squeeze the ball 122, causing the ball 122 to move outward and embed into the mounting hole 132, thereby fixing the sampling component 13 onto the mounting component 12. Furthermore, the sampler 1 can be disassembled into four parts: the main component 11, the mounting component 12, the sampling component 13, and the auxiliary component 14, making it convenient to carry when used outdoors.

[0031] Specifically, the mounting assembly 12 also includes a pull rod 126 fixed to the upper end of the guide rod 123, and waist-shaped holes 127 opened at both ends of the mounting base 121, with the end of the pull rod 126 passing through the waist-shaped hole 127.

[0032] In this embodiment, by pulling the pull rod 126 to slide along the waist-shaped hole 127, the pull rod 126 drives the guide sleeve 124 to disengage from the ball 122 through the guide rod 123, so that the ball 122 can move inward, thereby allowing the sampling component 13 to be removed from or installed on the mounting component 12.

[0033] Specifically, the main body component 11 also includes a number of adjustment holes 114 evenly distributed on the outer rod 111, a spring plate 115 installed inside the inner rod 112, with the outer wall of the left end of the spring plate 115 fixed to the inner wall of the inner rod 112, and a protrusion 116 fixed to the outer wall of the right end of the spring plate 115, with the protrusion 116 penetrating the inner rod 112 and extending into the adjustment hole 114.

[0034] In this embodiment, by pressing the protrusion 116 to squeeze the spring sheet 115, the protrusion 116 is disengaged from the adjustment hole 114, thereby allowing the inner rod 112 to be pulled out from the outer rod 111. When pulled to a suitable length, the spring sheet 115 pushes the protrusion 116 into the corresponding adjustment hole 114, thereby fixing the inner rod 112 and the outer rod 111. The length of the sampler 1 can be adjusted and fixed to adapt to different situations.

[0035] Specifically, the main body component 11 also includes a threaded hole 117 opened inside the upper end of the inner rod 112, and the grip 113 is threadedly installed in the threaded hole 117.

[0036] In this embodiment, the grip 113 can be detached from the outer rod 111.

[0037] Specifically, the sampler 1 also includes a frame 141 fitted and installed at the lower end of the outer rod 111, an extension frame 142 fixed to the outer walls at both ends of the frame 141, a pedal 143 installed at the upper end of the extension frame 142, and grooves 144 opened on the outer walls of the four corners of the frame 141.

[0038] In this embodiment, when the soil is hard, the auxiliary component 14 can be stepped on forcefully to make the sampling component 13 penetrate deeper into the soil.

[0039] Specifically, the sampler 1 also includes bolts 15 installed through the four corners of the fixing frame 118, and the lower end of the bolts 15 penetrates the upper end of the mounting base 121, with nuts 16 threaded onto the bolts 15.

[0040] In this embodiment, the main component 11 and the mounting component 12 are fixed together by an auxiliary component 14 and bolts 15, and the auxiliary component 14 can also be fixed at the same time.

[0041] The working principle and usage process of this utility model are as follows: First, by pulling the pull rod 126, it slides along the waist-shaped hole 127. At the same time, the pull rod 126 drives the guide sleeve 124 to disengage from the ball 122 through the guide rod 123, so that the ball 122 can move inward, thereby allowing the sampling head 131 to be sleeved and installed on the mounting base 121.

[0042] Then, the pulled rod 126 is released and the guide sleeve 124 is pushed by the pressure of the spring 125 to squeeze the ball 122, so that the ball 122 moves outward and is embedded in the mounting hole 132, thereby fixing the sampling component 13 on the mounting component 12.

[0043] Finally, by pressing the protrusion 116 to squeeze the spring sheet 115, the protrusion 116 is disengaged from the adjustment hole 114, so that the inner rod 112 can be pulled out from the outer rod 111. When it is pulled out to a suitable length, the spring sheet 115 pushes the protrusion 116 into the corresponding adjustment hole 114 by the pressure of the spring, thereby fixing the inner rod 112 and the outer rod 111. The length of the sampler 1 can be adjusted and fixed to adapt to different situations.
