Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and in particular to a soil sampling and detection device for soil remediation. Background Art

[0002] Soil environmental monitoring refers to the determination of representative values ​​of factors that affect soil environmental quality. Acidic or alkaline soils will reduce the effectiveness of soil nutrients to varying degrees, making it difficult to form a good soil structure and severely inhibiting the activity of soil microorganisms, thereby affecting the growth and development of various crops. Soil acidity and alkalinity play a key role in the planting industry. Currently, when sampling soil, it is necessary to sample soil at different depths and then insert a detection cone into the soil for testing.

[0003] Existing soil sampling and testing devices usually insert a hollow pipe into the soil for soil collection. When the hollow pipe is filled with soil and soil is extracted from the soil, the soil is likely to slide inside the pipe, resulting in soil loss and poor sampling effect. In addition, the position of the soil inside the hollow pipe will change during the sliding process, making it inconvenient for users to judge the depth of the soil sample obtained in the soil, further reducing the detection effect. Summary of the invention

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a soil sampling and detection device for soil remediation, which effectively prevents the soil from sliding inside the hollow pipe due to the action of gravity, prevents the soil position from changing, and ensures that the user can judge the depth of the soil sample in the soil.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A soil sampling and detection device for soil remediation comprises a fixed frame, a first electric push rod fixedly connected to the top of the fixed frame, the push rod vertically extending downward into the fixed frame, and a detection rod fixedly connected to the bottom end of the push rod; a second electric push rod fixedly connected to the inner top wall of the detection rod, the push rod vertically extending downward, and a driving rod fixedly connected to the bottom end of the push rod; the driving rod is provided with a slide groove, sampling boxes arranged at equal distances are inserted on the left and right sides of the detection rod, an inclined groove is provided on one side of the sampling box, two groups of sliding rods arranged at equal distances are fixed in the slide groove, and the sliding rod is located in the inclined groove; the first electric push rod drives the second detection rod to insert into the soil, and the second electric push rod drives the sampling box to insert into the soil for sampling, a driving structure is installed at the bottom of the fixed frame, the driving structure is connected to the detection cone, and the driving structure drives the detection cone to insert into the sampling box to detect the soil inside.

[0007] A horizontal mounting plate is provided at the bottom of the fixed frame, and the driving structure includes a rotating disk, the bottom of the rotating disk is rotatably connected to the mounting plate, and a motor fixedly connected to the fixed frame is inserted on the left side, and the output shaft of the motor is meshed with the rotating disk through a gear.

[0008] The mounting plate is interspersed with two slide plates slidably connected thereto, the two slide plates are respectively fixedly connected to the two detection cones, the tops of the two slide plates are in contact with the inner side of the rotating disk, the inner wall of the rotating disk is fixedly connected to a plurality of arc blocks, and a spring is sleeved on the detection cone.

[0009] The motor drives the rotating disk to rotate, and the arc-shaped block on the inner wall of the rotating disk pushes the sliding plate to move left and right, thereby driving the detection cone to move left and right.

[0010] The inner wall of the detection rod is fixedly connected to two third electric push rods, the top end of the third electric push rod is fixedly connected to a square rod, and the round rods arranged at equal distances are fixedly connected to the square rod; the inner wall of the sampling box is interspersed with a cleaning block slidably connected to it, and an L-shaped groove is provided on the cleaning block, and the round rods are inserted into the L-shaped groove; the third electric push rod drives the square rod to move up and down, drives the round rod to slide along the L-shaped groove, and then drives the cleaning block to slide left and right along the inner wall of the sampling box for cleaning.

[0012] The front side of the fixing frame is fixedly connected with a controller, and the controller is electrically connected with the first electric push rod, the second electric push rod and the third electric push rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention replaces the existing method of collecting soil through a hollow pipe, effectively preventing the soil from sliding inside the hollow pipe due to gravity, preventing the soil position from changing, and causing the user to be unable to judge the depth of the soil sample in the soil. After the sampling box of the device is inserted into the soil, the user turns on the first electric push rod again, and the first electric push rod will drive the detection rod to move downward. During the descent of the detection rod, the sampling box will also descend. After the sampling box descends, the soil inside the sampling box will be cut off from the soil outside, thereby effectively preventing the viscosity of the soil in the sampling box from causing the soil inside the sampling box to be lost during the process of the sampling box shrinking into the detection rod, thereby improving the practicality of the device.

[0020] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0021] like Figure 1-4 As shown, a soil sampling and testing device for soil remediation includes a fixed frame 1. The fixed frame 1 is a rectangular frame structure, which is composed of a horizontal top frame and left and right vertical frames vertically fixed on both sides of the horizontal top frame.

[0022] The horizontal top frame of the fixed frame 1 is interspersed with a first electric push rod 2 fixedly connected thereto, the first electric push rod 2 is vertically arranged, the bottom end of the first electric push rod 2 is fixedly connected to a detection rod 3, the inner top wall of the detection rod 3 is fixedly connected to a second electric push rod 4, the second electric push rod 4 is vertically arranged, and the bottom end of the second electric push rod 4 is fixedly connected to a driving rod 5.

[0023] Two slide grooves 6 are provided on the front of the driving rod 5, and sampling boxes 7 arranged at equal distances are inserted on both the left and right sides of the detection rod 3. An inclined groove 8 is provided on one side of the sampling box 7. Two groups of slide bars 9 arranged at equal distances are fixedly connected to the front of the two slide grooves 6. The slide bars 9 are located in the inclined grooves 8, and the inner wall of the inclined grooves 8 is in contact with the slide bars 9. The inner side of the left and right vertical frames of the fixed frame 1 is fixedly connected with a mounting plate 10, and two detection cones 11 slidably connected to the inner side of the mounting plate 10 are inserted, and a driving structure 12 is provided on the mounting plate 10, and the bottom of the driving structure 12 is respectively connected to the two detection cones 11.

[0024] When in use, the device is first placed above the soil to be detected, and then the user starts the first electric push rod 2, which drives the detection rod 3 to be inserted into the soil. After the detection rod 3 is completely inserted into the soil, the user starts the second electric push rod 4, which drives the driving rod 5 to descend after it is started, and drives the slide bar 9 to descend during the descent of the driving rod 5. After the slide bar 9 descends, it squeezes the inner wall of the chute 8 in contact with it, and after the chute 8 is squeezed, it drives the corresponding sampling box 7 to be inserted into the soil. After the sampling box 7 is inserted into the soil, the soil enters the sampling box 7 to complete the collection of the soil. At this time, the user reversely starts the second electric push rod 4, and the second electric push rod 4 drives the slide bar 9 to slide in the opposite direction along the inner wall of the chute 8, and then re-enters the sampling box 7 into the detection rod 3, and then reversely opens the first electric push rod 2, and the first electric push rod 2 drives the detection rod 3 to be pulled out of the soil. In the process of extracting from the soil, the user starts the driving structure 12, and the driving structure 12 drives the detection cone 11 to reciprocate left and right. When each sampling box 7 passes through one side of the detection cone 11 and is aligned with it, the detection cone 11 will be inserted into the sampling box 7. After the detection cone 11 contacts the soil inside the sampling box 7, the soil is detected. The present invention replaces the existing method of collecting soil through a hollow pipe, effectively avoiding the situation that the soil slides inside the hollow pipe due to the action of gravity, avoiding the change of the soil position, resulting in the user being unable to judge the depth of the soil sample in the soil, and after the sampling box 7 of the device is inserted into the soil, the user starts the first electric push rod 2 again, and the first electric push rod 2 drives the detection rod 3 to move downward. During the descent of the detection rod 3, the sampling box 7 will descend. After the sampling box 7 descends, the soil inside the sampling box 7 will be cut off from the soil outside, thereby effectively avoiding the situation that the viscosity between the soils causes the soil inside the sampling box 7 to be lost during the process of the sampling box 7 shrinking into the detection rod 3, thereby improving the practicality of the device.

[0025] like Figure 1-3 As shown, the driving structure 12 includes a rotating disk 121, the bottom of which is rotatably connected to the mounting plate 10, a motor 122 fixedly connected to the fixed frame 1 is inserted on the left side of the fixed frame 1, the output shaft of the motor 122 is meshed with the rotating disk 121 through a gear, and two slide plates 123 slidably connected to the mounting plate 10 are inserted on the top of the mounting plate 10, the opposite sides of the two slide plates 123 are respectively fixedly connected to the two detection cones 11, the tops of the two slide plates 123 are in contact with the inner side of the rotating disk 121, and two arc blocks 124 are fixedly connected to the inner wall of the rotating disk 121, and springs 125 are provided on the two detection cones 11.

[0026] When in use, start the motor 122. After the motor 122 is started, it will drive the gear to rotate. After the gear rotates, it will drive the rotating disk 121 to rotate. After the rotating disk 121 rotates, it will drive the arc block 124 to rotate. After the arc block 124 rotates, the slide plate 123 will continuously slide over the arc block 124. During the sliding process of the slide plate 123 along the arc block 124, the slide plate 123 will be displaced. After the slide plate 123 is displaced, it will drive the detection cone 11 to slide until the slide plate 123 slides over the arc block 124. At this time, the slide plate 123 loses the support of the arc block 124, and the elastic force of the spring 125 will reset the slide plate 123 and drive the detection cone 11 to run in the opposite direction, thereby achieving the purpose of driving the detection cone 11 to reciprocate left and right.

[0027] like Figure 4 As shown, the inner wall of the detection rod 3 is fixedly connected with two third electric push rods 13, the top ends of the two third electric push rods 13 are fixedly connected with square rods 14, and the two square rods 14 are fixedly connected with round rods 15 arranged at equal distances, and the inner wall of the sampling box 7 is interspersed with a cleaning block 16 slidably connected thereto, and an L-shaped groove 17 is provided on the cleaning block 16, and one end of the back of the round rod 15 contacts the inner wall of the L-shaped groove 17. After the soil detection inside the sampling box 7 is completed, the user starts the third electric push rod 13, and the third electric push rod 13 will drive the square rod 14 to rise, and the square rod 14 will drive the round rod 15 to squeeze the inner wall of the L-shaped groove 17 during the rising process, and the inner wall of the L-shaped groove 17 will then drive the cleaning block 16 to slide along the inner wall of the sampling box 7 after being squeezed, and the cleaning block 16 will push the soil inside the sampling box 7 out during the sliding process, thereby cleaning the sampling box 7, making it convenient for the user to use the device again, thereby improving the practicality of the device.

[0028] like Figure 1 , Figure 2 As shown, a controller 18 is fixedly connected to the front of the fixing frame 1, and the output end of the controller 18 is respectively electrically connected to the first electric push rod 2, the second electric push rod 4 and the third electric push rod 13. The controller 18 fixedly connected to the front of the fixing frame 1 can facilitate the user to control the first electric push rod 2, the second electric push rod 4 and the third electric push rod 13, thereby improving the practicality of the device.

[0029] like Figure 1 , Figure 2 As shown, a handle 19 is fixedly connected to the top of the fixing frame 1, and an anti-slip pattern is provided on the surface of the handle 19. The handle 19 fixedly connected to the top of the fixing frame 1 can facilitate the user to carry the device, thereby improving the portability of the device.

[0030] The working principle and working process of the present invention are as follows:

[0031] When in use, first place the device above the soil to be detected, then the user starts the first electric push rod 2, the first electric push rod 2 drives the detection rod 3 to be inserted into the soil, after the detection rod 3 completely enters the soil, the user starts the second electric push rod 4, after the second electric push rod 4 is started, it will drive the driving rod 5 to descend, and during the descent of the driving rod 5, it will drive the sliding rod 9 to descend, and after the sliding rod 9 descends, it will squeeze the inner wall of the inclined groove 8 in contact with it, and after the inclined groove 8 is squeezed, it will drive the corresponding sampling box 7 to be inserted into the soil, after the sampling box 7 is inserted into the soil, the soil will enter the sampling box 7 and complete the collection of the soil, at this time, the user starts the second electric push rod 4 in the reverse direction, the second electric push rod 4 will drive the sliding rod 9 to slide in the reverse direction along the inner wall of the inclined groove 8, and then re-enter the sampling box 7 into the detection rod 3, and then reversely open the first electric push rod 2, the first electric push rod 2 drives the detection rod 3 to be pulled out of the soil.

[0032] And in the process of extracting from the soil, the user starts the motor 122. After the motor 122 is started, it drives the gear to rotate. After the gear rotates, it drives the rotating disk 121 to rotate. After the rotating disk 121 rotates, it drives the arc block 124 to rotate. After the arc block 124 rotates, the slide plate 123 will continue to slide over the arc block 124. In the process of sliding into the arc block 124, the slide plate 123 is displaced. After the slide plate 123 is displaced, it drives the detection cone 11 to slide until the slide plate 123 slides over the arc block 124. At this time, the slide plate 123 loses the support of the arc block 124, and the elastic force of the spring 125 will reset the slide plate 123 and drive the detection cone 11 to run in the opposite direction, thereby achieving the purpose of driving the detection cone 11 to reciprocate left and right. When each sampling box 7 passes through one side of the detection cone 11 and is aligned with it, the detection cone 11 will be inserted into the sampling box 7. After the detection cone 11 contacts the soil inside the sampling box 7, the soil is detected.

[0033] The process replaces the existing method of collecting soil through a hollow pipe, effectively preventing the soil from sliding inside the hollow pipe due to gravity, preventing the soil position from changing, and causing the user to be unable to judge the depth of the soil sample in the soil. After the sampling box 7 of the device is inserted into the soil, the user turns on the first electric push rod 2 again, and the first electric push rod 2 will drive the detection rod 3 to move downward. During the descent of the detection rod 3, the sampling box 7 will also descend. After the sampling box 7 descends, the soil inside the sampling box 7 will be cut off from the soil outside, thereby effectively preventing the viscosity of the soil from causing the soil inside the sampling box 7 to be lost during the process of the sampling box 7 shrinking into the detection rod 3, thereby improving the practicability of the device.

[0034] The present invention effectively prevents the soil from sliding inside the hollow pipe due to the effect of gravity, prevents the soil position from changing, and ensures that the user can judge the depth of the soil sample in the soil.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
