Description

Technical Field

[0001] This utility model relates to the field of soil sampling equipment technology, and in particular to an electric soil sampler. Background Technology

[0002] In soil-related research and testing, soil sampling is a crucial step in obtaining basic data. Electric soil samplers, with their advantages of high sampling efficiency and labor-saving operation, have gradually replaced traditional manual samplers and are widely used in various scenarios. Existing electric soil samplers typically consist of a power unit, transmission mechanism, sampling cylinder, and handheld support. During operation, the power unit drives the transmission mechanism to rotate the sampling cylinder and drill downwards into the soil, collecting soil samples through the cavity of the sampling cylinder.

[0003] However, because soil samples adhere tightly to the inner wall of the sampling tube due to factors such as compression and humidity, after sampling, operators need to use tools (such as push rods) to forcibly peel the soil sample from the sampling tube. This is not only cumbersome and time-consuming, but also easily leads to soil sample breakage and disordered stratification, damaging the original structure and state of the soil sample, and thus affecting the accuracy of subsequent test data.

[0004] Therefore, in view of the above situation, there is an urgent need to develop an electric soil sampler to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide an electric soil sampler, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electric soil sampler includes a support plate, a motor fixedly connected to the bottom end of the support plate, a fixed cylinder fixedly connected to the drive end of the motor, a drill cylinder slidably connected to the inner wall of the fixed cylinder, and a fixing component provided between the fixed cylinder and the drill cylinder. The bottom end of the drill cylinder has drill teeth, and the inner wall of the drill cylinder has a placement groove. The bottom end of the placement groove has multiple evenly distributed slots. The inner wall of the placement groove has multiple interlocking semi-sampling cylinders slidably connected to it. A connecting component is provided between adjacent semi-sampling cylinders. The lower end of each semi-sampling cylinder is fixedly connected to a clamp head, and the clamp head engages with the slot.

[0008] In a further technical solution, a handle is fixedly connected to the inner wall of each of the semi-sampling cylinders.

[0009] In a further technical solution, the fixing component includes a first locking hole, a locking bolt, a second locking hole, a limiting rod, and a limiting groove; the fixing cylinder has a plurality of circumferentially evenly distributed first locking holes, and the drill cylinder has a plurality of circumferentially evenly distributed second locking holes, and the second locking holes correspond one-to-one with the first locking holes, and the first locking holes and the second locking holes are internally threaded with locking bolts.

[0010] In a further technical solution, the inner wall of the fixed cylinder is provided with a plurality of circumferentially evenly distributed limiting grooves, and the outer wall of the drill cylinder is fixedly connected with a plurality of circumferentially evenly distributed limiting rods, and the limiting rods are slidably connected to the limiting grooves.

[0011] A further technical solution is that when the top of the fixed cylinder abuts against the upper surface of the semi-sampling cylinder, the center lines of the first locking hole and the corresponding second locking hole are collinear.

[0012] In a further technical solution, the connecting component includes a T-slot and a T-plate; a T-plate is fixedly connected to the side of the half-sampling cylinder, and a T-slot is opened on the side of the adjacent half-sampling cylinder, and the T-slot and the T-plate are slidably connected.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. The fixed cylinder is attached to the drill pipe, and the fixed cylinder and the drill pipe are fixed together by the fixing component. The fixed cylinder is driven by the motor to rotate, and the fixed cylinder drives the drill pipe to rotate. The drill pipe drives the semi-sampling cylinder to rotate through the cooperation of the chuck and the slot. By manually supporting and pressing the support plate, the drill pipe is pushed forward and soil samples are collected through the semi-sampling cylinder. The semi-sampling cylinder is pulled out by the handle, and then the two semi-sampling cylinders are slid apart to completely remove the soil sample, thus preserving the original structure and state of the soil sample, which is beneficial to the accuracy of subsequent test data.

[0015] 2. Fit the fixed sleeve onto the outer wall of the drill barrel. During this process, align the limiting rod with the limiting groove and slide the limiting rod along the inner wall of the limiting groove until the top of the fixed sleeve abuts against the half-sampling cylinder. Then screw the locking bolt into the first locking hole and the second locking hole to fix the drill barrel and the fixed sleeve together. The operation is simple and quick.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] like Figures 1-5 As shown, this utility model embodiment provides an electric soil sampler, including a support plate 1. A motor 2 is fixedly connected to the bottom end of the support plate 1. A fixed cylinder 3 is fixedly connected to the drive end of the motor 2. A drill cylinder 4 is slidably connected to the inner wall of the fixed cylinder 3. A fixing component 6 is provided between the fixed cylinder 3 and the drill cylinder 4. Drill teeth 5 are provided at the bottom end of the drill cylinder 4. A placement groove 7 is provided on the inner wall of the drill cylinder 4. A plurality of evenly distributed slots 10 are provided at the bottom end of the placement groove 7. A plurality of interconnected semi-sampling cylinders 8 are slidably connected to the inner wall of the placement groove 7. A connecting component 11 is provided between adjacent semi-sampling cylinders 8. A clamping head 9 is fixedly connected to the lower end of each semi-sampling cylinder 8, and the clamping head 9 engages with the slot 10.

[0026] Furthermore, each of the semi-sampling cylinders 8 is fixedly connected to a handle 12, which facilitates pulling the semi-sampling cylinder 8 out of the drill cylinder 4.

[0027] like Figures 1-4As shown, the fixing component 6 includes a first locking hole 61, a locking bolt 62, a second locking hole 63, a limiting rod 64, and a limiting groove 65; the fixing cylinder 3 has a plurality of circumferentially evenly distributed first locking holes 61, and the drill cylinder 4 has a plurality of circumferentially evenly distributed second locking holes 63, and the second locking holes 63 correspond one-to-one with the first locking holes 61, and the first locking holes 61 and the second locking holes 63 are internally threaded with locking bolts 62.

[0028] Furthermore, the inner wall of the fixed cylinder 3 is provided with a plurality of circumferentially evenly distributed limiting grooves 65, and the outer wall of the drill cylinder 4 is fixedly connected with a plurality of circumferentially evenly distributed limiting rods 64, and the limiting rods 64 are slidably connected to the limiting grooves 65.

[0029] Furthermore, when the top end of the fixed cylinder 3 abuts against the upper end face of the semi-sampling cylinder 8, the axis of the first locking hole 61 and the corresponding second locking hole 63 are collinear, thereby enabling quick alignment of the first locking hole 61 and the second locking hole 63, which facilitates screwing the locking bolt 62 into the first locking hole 61 and the second locking hole 63, thereby improving work efficiency.

[0030] In practical application, the fixing cylinder 3 is sleeved on the outer wall of the drill cylinder 4. During this process, the limiting rod 64 is aligned with the limiting groove 65, and the limiting rod 64 slides along the inner wall of the limiting groove 65 until the top of the fixing cylinder 3 abuts against the semi-sampling cylinder 8. Then, the locking bolt 62 is screwed into the first locking hole 61 and the second locking hole 63, thereby fixing the drill cylinder 4 and the fixing cylinder 3 together.

[0031] like Figure 5 As shown, the connecting assembly 11 includes a T-slot 111 and a T-plate 112; the T-plate 112 is fixedly connected to the side of the half-sampling cylinder 8, and the adjacent half-sampling cylinder 8 has a T-slot 111 on its side, and the T-slot 111 and the T-plate 112 are slidably connected.

[0032] In practical application, first place one half-sampling cylinder 8 into the placement groove 7 until the clip 9 is inserted into the slot 10. Then, continue to insert the other half-sampling cylinder 8 into the placement groove 7, and insert the T-shaped plate 112 into the T-shaped groove 111 until the clip 9 on the half-sampling cylinder 8 is inserted into the corresponding slot 10.

[0033] In this embodiment of the invention, a fixed cylinder 3 is sleeved onto a drill cylinder 4, and the fixed cylinder 3 and the drill cylinder 4 are fixed together by a fixing component 6. The fixed cylinder 3 is driven to rotate by the drive end of the motor 2, which in turn drives the drill cylinder 4 to rotate. The drill cylinder 4 drives the semi-sampling cylinder 8 to rotate through the cooperation of the chuck 9 and the chuck 10. By manually supporting and pressing the support plate 1, the drill cylinder 4 is pushed forward and soil samples are collected through the semi-sampling cylinder 8. The semi-sampling cylinder 8 is pulled out by the handle 12, and then the two semi-sampling cylinders are... 8. Slide the tubes apart to completely extract the soil sample, thus preserving the original structure and state of the soil sample, which is beneficial to the accuracy of subsequent test data; fit the fixing tube 3 onto the outer wall of the drill tube 4. During this process, align the limiting rod 64 with the limiting groove 65 and slide the limiting rod 64 along the inner wall of the limiting groove 65 until the top of the fixing tube 3 abuts against the half-sampling tube 8. Then screw the locking bolt 62 into the first locking hole 61 and the second locking hole 63 to fix the drill tube 4 and the fixing tube 3 together. The operation is simple and quick.

[0034] The working principle of this utility model is as follows: the semi-sampling cylinder 8 is placed in the placement groove 7, and the clamp 9 engages with the groove 10. Then, the fixing cylinder 3 is sleeved on the drill cylinder 4, and the fixing cylinder 3 and the drill cylinder 4 are fixed together by the fixing component 6. Then, the support plate 1 is supported and pressed. The drive end of the motor 2 drives the fixing cylinder 3 to rotate, and the fixing cylinder 3 drives the drill cylinder 4 to rotate. The drill cylinder 4 drives the semi-sampling cylinder 8 to rotate by the cooperation of the clamp 9 and the groove 10, thereby pushing the drill cylinder 4 to feed and collect soil samples through the semi-sampling cylinder 8. After sampling is completed, the device is pulled out, and then the fixing cylinder 3 is removed. Then, the semi-sampling cylinder 8 is pulled out by the handle 12, and then the two semi-sampling cylinders 8 are slid apart to completely extract the soil sample.

[0035] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
