[0031] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0032] refer to Figures 1 to 6 As shown, an electric powered soil sampler comprises a motor 1 and a sampling tube, wherein the motor 1 is provided with a handle 11, and the sampling tube comprises an outer cylinder 2 and an inner cylinder 3, wherein two second rows of soil holes 31 for soil to enter are provided on the top surface of the inner cylinder 3, and the two second rows of soil holes 31 are located opposite to each other, and a plurality of elastic fenders 32 are provided near the opening of the inner peripheral wall of the inner cylinder 3, and the fenders 32 are inclined upward and have a certain elasticity, so that when soil enters the inner cylinder 3 from below, the fenders 32 will not block the soil, and when soil falls out of the inner cylinder 3, the soil will not fall due to the blocking of the fenders 32; a connecting rod 33 of a certain length is vertically welded at the center position of the top surface of the inner cylinder 3, and the end of the connecting rod 33 away from the inner cylinder 3 is connected to the output end of the motor 1;

[0033] The outer cylinder 2 is provided with a connecting hole at the center of the top surface, and the outer cylinder 2 is movably mounted on the outside of the inner cylinder 3 through the connecting hole and the connecting rod 33. The length of the outer cylinder 2 is greater than the length of the inner cylinder 3. The top surface of the outer cylinder 2 is also provided with two second rows of soil holes 21 for soil entry, and the second row of soil holes 21 corresponds to the position of the first row of soil holes 31, and the first row of soil holes 31 and the second row of soil holes 21 have the same shape and size. The bottom of the outer cylinder 3 is provided with a sharp blade 22, and the blade 22 is a sawtooth A mounting rod 23 of a certain length is vertically welded at the center of the top surface of the outer cylinder 2. The interior of the mounting rod 23 is hollow and is sleeved outside the connecting rod 33. A through hole 231 is provided at the end of the mounting rod 23 away from the outer cylinder 2. A fixing pin 24 is slidably penetrated in the through hole 231. A first pin hole 332 and a second pin hole 333 are provided at the corresponding position of the connecting rod 33 for inserting the fixing pin 24. The first pin hole 332 and the second pin hole 333 are cross-shaped. Figure 4 As shown, when the fixing pin 24 passes through the through hole 231 and the first pin hole 332, the first soil row hole 31 and the second soil row hole 21 are aligned. The fixing pin 24 fixes the mounting rod 23 outside the connecting rod 33, so that the outer cylinder 2 and the inner cylinder 3 rotate simultaneously through the connecting rod 33 with the motor 1.

[0034] The end of the connecting rod 33 away from the inner cylinder 3 is also connected to the extension rod 4, and the extension rod 4 is connected to the connecting rod 33 through a connecting assembly. The connecting assembly includes a mounting sleeve 41 and a threaded connecting column 42. The mounting sleeve 41 is welded to the end of the extension rod 4 away from the output end of the motor 1. The inner wall of the mounting sleeve 41 is provided with an internal thread. The end of the connecting rod 33 away from the inner cylinder 3 is recessed inward to form a cylindrical groove 331. The inner circumferential wall of the groove 331 is provided with an internal thread. The outer circumferential wall of the end of the connecting rod 33 away from the inner cylinder 3 is also provided with an external thread. The internal thread on the inner wall of the mounting sleeve 41 is connected to the connecting rod 33 away from the inner cylinder 3. The external thread on one end of the cylinder 3 matches, and the inner diameter of the mounting sleeve 41 is the same as the diameter of the connecting rod 33. A vertical threaded connecting column 42 is welded at the center position of the inner upper surface of the mounting sleeve 41. The diameter of the threaded connecting column 42 is the same as the diameter of the groove 331, and the thread of the threaded connecting column 42 matches the internal thread on the inner wall of the groove 331. The extension rod 4 and the connecting rod 33 are fixedly connected at one end away from the inner cylinder 3 through the connecting assembly, and then the end of the extension rod 4 away from the connection with the connecting rod 33 is connected to the output end of the motor 1, so that when the depth of the sampling tube inserted into the soil can be adjusted, the sampler can sample and detect soils of different depths.

[0035] In this embodiment, when the connecting rod 33 is connected to the output end of the motor 1 through the extension rod 4, the sampling tube can sample deeper soil. However, since the length of the mounting rod 23 has not changed, the end of the mounting rod 23 with the fixed plug 24 is likely to enter the sampling hole during soil sampling, making it impossible for the staff to operate the outer cylinder 2 through the mounting rod 23. Therefore, when necessary, an extension sub-rod is also connected to the end of the rotating rod 23 away from the outer cylinder 2. The interior of the extension sub-rod is empty and can also be sleeved on the outside of the connecting rod 33. The length of the extension sub-rod is the same as that of the extension rod 4. When the extension rod 4 and the extension sub-rod are installed on the connecting rod 33 and the mounting rod 23 at the same time, the extension rod 4 and one end are also provided with a first plug sub-hole and a second plug sub-hole. The end of the extension sub-rod close to the motor 1 is provided with a sub-through hole. The first plug sub-hole and the second plug sub-hole are also Figure 4 The cross-shaped cross shown in the figure enables the sampling passage to perform depth sampling through the extension rod 4 and the extension sub-rod, and the extension sub-rod can also fix the position of the outer cylinder 2 through the fixing pin 24.

[0036] In this embodiment, a conical protrusion with a pointed end facing downward may be provided on the top surface of the inner cylinder 3 between the two second rows of soil holes 31, and the edge where the conical protrusion contacts the top surface of the inner cylinder 3 is located at the inner edge of the two second rows of soil holes 31. When the soil is discharged through the second rows of soil holes 31, the conical protrusion can allow the soil at the center of the inner cylinder 3 to be discharged through the second rows of soil holes 31, thereby preventing the soil from accumulating at the center of the inner cylinder 3.

[0037] Working principle: When soil sampling is required, first adjust the positions of the outer cylinder 2 and the inner cylinder 3 so that the positions of the first row of soil holes 31 and the second row of soil holes 21 are aligned, and then insert the fixing pin 24 into the through hole 231 and the pin hole 332 to fix the outer cylinder 2. Then the staff inserts the blade 22 into the soil through the handle 11, and then starts the motor 1 to rotate, thereby driving the outer cylinder 2 and the inner cylinder 3 to rotate and penetrate into the ground through the connecting rod 33. When the sampling cylinder does not reach the specified position, the excess soil enters the inner cylinder 3 from the bottom. Since the mud guard 32 is tilted upward, the excess soil is discharged from the sampling cylinder through the first row of soil holes 31 and the second row of soil holes 21. When it reaches the specified position, first pull out the fixing pin 24, then rotate the mounting rod 23 90 degrees, and then Drive the outer cylinder 2 to rotate 90 degrees, and then insert the fixed pin 24 into the through hole 231 and the second pin hole 333. Since the outer cylinder 2 rotates 90 degrees, the side wall of the outer cylinder 2 without the second row of soil holes 21 blocks the first row of soil holes 31 on the inner cylinder 3. At this time, the staff pulls the connecting rod 33 upward to drive the sampling tube to move and move the sampling tube out of the underground. The mud guard 32 has a certain elasticity to block the soil of the inner cylinder 3, thereby preventing the sampling tube from falling during the upward movement, resulting in sampling failure. If deeper soil sampling is to be carried out, it is only necessary to install the extension rod 4 and the extension sub-rod together with the connecting rod 33 and the mounting rod 23, and then the end of the extension rod 4 away from the connecting component is connected to the output end of the motor 1 to continue sampling.

[0038] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
