A portable soil testing kit

Abstract

The application discloses a portable soil detection box, and relates to the technical field of detection boxes, which comprises a box body, and a partition plate is fixedly installed on the inner wall of the four sides of the box body. When the application is used, soil is put in, and the soil falls on one of the horizontally upward opening filter boxes. The filter box can move back and forth by starting the driving mechanism, so that the soil is screened. The soil can be detected by the detection mechanism. At this time, the impurities fall in the filter box. Then, the filter box containing the impurities is rotated by the rotating mechanism. The clean filter box at the bottom is rotated to the horizontally upward opening state, so that the next detection is facilitated. When the filter box containing the impurities is rotated to the horizontally inverted state, the horizontally inverted filter box can be vibrated by the driving mechanism, so that the filter box is cleaned. In the rotating process of the rotating mechanism, the cleaning mechanism is avoided and the detection mechanism is cleaned at the same time, so that continuous detection is facilitated.

[0002] Soil is generally composed of three phases: solid, liquid, and gas, including minerals, organic matter, water, and air. Before analysis, soil samples need to be processed.

[0018] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily exceeds the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but still fall within the protection scope of this application.

[0019] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-9 The present invention will be further described below.

[0020] This invention discloses a portable soil testing box, including a box body 1. Partitions 6 are fixedly installed on the four inner walls of the box body 1. Four filter boxes 7 are installed on the sides of the partitions 6 through a drive mechanism. A collection block 38 is fixedly installed on the bottom inner wall of the box body 1 below one of the filter boxes 7. A testing mechanism is installed on the collection block 38. A cleaning mechanism is installed on the side of the partitions 6. The cleaning mechanism is installed in conjunction with the drive mechanism. A rotating mechanism is fixedly installed on the side of the box body 1. The rotating mechanism is in conjunction with the drive mechanism. The drive mechanism includes a mounting sleeve 8. The inner wall of the mounting sleeve 8 has four evenly spaced arc-shaped holes 10. A rectangular sleeve 9 is slidably installed in each of the four arc-shaped holes 10. A rectangular rod 15 is slidably installed in each of the four rectangular sleeves 9. The ends of the four rectangular rods 15 that are far apart from each other extend to the outside of the four rectangular sleeves 9 and are fixedly connected to the sides of the four filter boxes 7 respectively. A pressing plate 16 is fixedly installed at the ends of the four rectangular rods 15 that are close to each other. The pressing plate 16 is connected to the side of the rectangular sleeve 9 through a first reset component. The rectangular sleeve 9 is connected to the inner wall of the mounting sleeve 8 through a second reset component. A pressure rod 17 is fixedly installed on the side of each of the four rectangular sleeves 9.

[0021] With the above structure: In use, soil is placed in and falls onto one of the filter boxes 7 with its opening facing upwards. By activating the drive mechanism, the filter box 7 moves back and forth, thus screening the soil. The soil can be detected by the detection mechanism. At this time, impurities fall into the filter box 7. Then, the rotating mechanism drives the filter box 7 containing impurities to rotate. The clean filter box 7 below rotates to the horizontal opening position, which is convenient for the next detection. At the same time, when the filter box 7 containing impurities rotates to the horizontal flip position, the drive mechanism can make the horizontally flipped filter box 7 vibrate, thereby cleaning it. During the rotation of the rotating mechanism, the cleaning mechanism will avoid obstacles and clean the detection mechanism at the same time, which is convenient for continuous detection.

[0022] like Figure 8 and Figure 9 As shown, the drive mechanism includes a circular hole on the side of the partition 6. One end of the mounting sleeve 8 passes through the circular hole and is fixedly fitted with a large gear 49. An internal motor 48 is fixedly installed on the vertical inner wall of the housing 1. The output shaft of the internal motor 48 is fixedly fitted with a small gear 50 that meshes with the large gear 49. A circular groove is provided on the other opposite vertical inner wall of the housing 1, and the other end of the mounting sleeve 8 is rotatably installed in the circular groove. The internal motor 48 can drive the small gear 50 to rotate counterclockwise, and the rotation of the small gear 50 drives the large gear 49 to rotate clockwise, thereby driving the mounting sleeve 8 to rotate. The rotation of the mounting sleeve 8 drives the four rectangular sleeves 9 and the four filter boxes 7 to rotate.

[0023] like Figure 3 and Figure 4As shown, the first reset assembly includes two movable springs 14, which are located on both sides of the rectangular rod 15. One end of each movable spring 14 is fixedly installed on the side of the extrusion plate 16, and the other end of the extrusion plate 16 is fixedly installed on the side of the rectangular sleeve 9. The second reset assembly includes two limiting rods 11 fixedly installed on the inner wall of the mounting sleeve 8. The top of the rectangular sleeve 9 is provided with limiting holes located on both sides of the rectangular rod 15. The two limiting rods 11 are slidably installed in the two limiting holes. Two limiting springs 13 are sleeved on each of the two limiting rods 11. Two limiting blocks 12 are fixedly sleeved on each of the two limiting rods 11. The two ends of the limiting springs 13 are fixedly installed on the sides of the rectangular sleeve 9 and the limiting blocks 12 that are close to each other. During the rotation of the four rectangular sleeves 9, when the positions of the extrusion plate 16 and the push rod 26 are not aligned, the push rod 26 will extrude the extrusion plate 16, causing the rectangular sleeve 9 to move along the direction of the limiting rod 11. The limiting spring 13 will deform, and during the back-and-forth movement of the push rod 26, the extrusion plate 16 and the push rod 26 will be misaligned. Under the action of the limiting spring 13, the extrusion plate 16 and the push rod 26 will be aligned. Similarly, when the positions of the pressure rod 17 and the extrusion column 18 are not aligned, the extrusion column 18 will extrude the pressure rod 17, causing the rectangular sleeve 9 to move along the direction of the limiting rod 11. The limiting spring 13 will deform, and during the rotation of the extrusion column 18, the pressure rod 17 will return to its original shape under the reaction force of the limiting spring 13.

[0024] like Figure 3 and Figure 4As shown, the rotating mechanism includes an external motor 3 fixedly installed on the side of the housing 1. A rotating shaft 20 is fixedly installed on the output shaft of the external motor 3. One end of the rotating shaft 20 passes through the inner wall of the housing 1 and is fixedly sleeved with an intermediate gear 21. Round rods 19, fixedly installed on the inner wall of the housing 1, are provided on both sides of the rotating shaft 20. Side gears 29 are rotatably installed on one end of each round rod 19. The central axes of the two round rods 19, the rotating shaft 20, and the mounting sleeve 8 are located on the same horizontal plane. An extrusion column 18 and an eccentric column 25 are eccentrically installed on the sides of the two side gears 29, respectively. The extrusion column 18 corresponds to the position of the pressure rod 17. By starting the external motor 3, the output shaft of the external motor 3 rotates, driving the rotating shaft 21 to rotate. Shaft 20 and intermediate gear 21 rotate. Intermediate gear 21 drives eccentric column 25 to rotate through a side gear 29. The eccentric column 25 rotates circumferentially to compress the inner wall of slot 27. There is a gap between the top and bottom inner walls of slot 27, which causes U-shaped plate 28 to move back and forth, and in turn causes push rod 26 to move back and forth. When push rod 26 approaches extrusion plate 16, it will drive extrusion plate 16, rectangular rod 15 and filter box 7 to move. Two moving springs 14 deform. When push rod 26 moves away from extrusion plate 16, the extrusion plate 16, rectangular rod 15 and filter box 7 return to their original positions under the action of the two moving springs 14, so that filter box 7 moves back and forth to screen the soil. During the rotation of the intermediate gear 21, the side gear 29 will rotate. The rotation of the side gear 29 will drive the squeezing column 18 to rotate clockwise. The clockwise rotation of the squeezing column 18 will squeeze the pressure rod 17 and make it move downward. The downward movement of the pressure rod 17 will drive the rectangular sleeve 9, the rectangular rod 15 and the flipped filter box 7 to move downward. The four limit springs 13 will deform. When the squeezing column 18 separates from the pressure rod 17, the rectangular sleeve 9 will return to its original shape under the force of the four limit springs 13. This will cause the flipped filter box 7 to hit the L-shaped plate 34, which will vibrate the filter box 7 and cause the impurities stuck on the filter box 7 to fall off, making it easier for the next inspection.

[0025] like Figure 3 and Figure 4 As shown, the rotating mechanism also includes two L-shaped fixed rods 24. The ends of the two L-shaped fixed rods 24 that are close to each other are fixedly installed on the side of the round rod 19 near the eccentric column 25. Slide rods 23 are fixedly installed on the sides of the two L-shaped fixed rods 24 near the extrusion column 18. Sliding sliders 22 are slidably sleeved on the two slide rods 23. U-shaped plates 28 are fixedly installed on the sides of the two sliding sliders 22 that are close to each other. A slot 27 is opened on the side of the U-shaped plate 28 away from the side gear 29. One end of the eccentric column 25 extends into the slot 27. A push rod 26 is fixedly installed on the side of the U-shaped plate 28 near the extrusion plate 16. One end of the push rod 26 contacts the side of the extrusion plate 16.

[0026] like Figure 6 and Figure 7As shown, the testing mechanism includes a conical hole 51 at the top of the collection block 38. The bottom side and the inner walls of the other two sides of the collection block 38 are fixedly connected to the three inner walls of the housing 1. The top of the collection block 38 is fixedly connected to the bottom of the sealing plate 45. The other vertical inner wall of the collection block 38 is fixedly connected to the side of the partition plate 6. The conical hole 51 corresponds to the position of the filter box 7. Discharge holes 53 are provided on the bottom inner wall of the conical hole 51 and the bottom inner wall of the housing 1. Discharge pipes 37 are fixedly installed in the two discharge holes 53. The bottom end of the discharge pipes 37 extends to the outside of the housing 1 and is equipped with a valve. After testing... After completion, soil can be discharged simply by opening the valve. For collection, a collection bottle can be placed below the discharge pipe 37. A detector 36 is fixedly installed on the side of the housing 1. A cavity 40 is formed in the collection block 38. An installation hole 52 communicating with a conical hole 51 is formed on one inner wall of the cavity 40. A sensor 44 is fixedly installed on the top inner wall of the cavity 40 via a fixing block 39. One end of the sensor 44 passes through the installation hole 52 and extends into the conical hole 51, while the other end is connected to the detector 36 via a wire. The detector 36 and sensor 44 allow for the testing of the filtered soil, facilitating its use.

[0027] like Figure 8 and Figure 9 As shown, the cleaning mechanism includes an insertion hole 54 on the side of the partition 6. An L-shaped plate 34 is slidably installed in the insertion hole 54. The top of the L-shaped plate 34 is located above the adjacent filter box 7. Two reset rods 32 are fixedly installed on the side of the partition 6. The L-shaped plate 34 is slidably sleeved on the two reset rods 32. Each of the two reset rods 32 is sleeved with a reset spring 33. One end of the two reset springs 33 is fixedly installed on the side of the partition 6, and the other end of the two reset springs 33 is fixedly installed on the vertical side of the L-shaped plate 34. An L-shaped mounting rod 35 is fixedly installed on the side of the L-shaped plate 34 away from the partition 6. A rotating wheel 47 is rotatably sleeved on the L-shaped mounting rod 35. Four evenly circumferentially arranged right-angled triangular holes 46 are opened on the inner wall of the mounting sleeve 8. The rotating wheel 47 contacts the inner wall of one of the right-angled triangular holes 46. When the mounting sleeve 8 rotates, the inclined inner wall of the right-angled triangular hole 46 presses against the rotating wheel 47, thereby causing the rotating wheel 47 and the L-shaped mounting rod 35 to move away from the partition 6. The movement of the L-shaped mounting rod 35 causes the L-shaped plate 34 to move away from the partition 6. When the rotating wheel 47 separates from the right-angled triangular hole 46, the top of the L-shaped plate 34 is offset from the filter box 7, so as not to affect the uppermost filter box 7 from rotating to the horizontal flip state. When the uppermost mounting sleeve 8 rotates to the horizontal flip state, the vertical side of the other right-angled triangular hole 46 corresponds to the rotating wheel 47. Under the action of the two return springs 33, the sliding sleeve 43 and the L-shaped plate 34 return to their original state.

[0028] like Figure 5 , Figure 6 and Figure 7 As shown, the cleaning mechanism also includes a pull rod 30 rotatably mounted on the side of the L-shaped plate 34. A driving rod 31 is rotatably mounted on the end of the pull rod 30 away from the L-shaped plate 34. A movable hole 55 is provided on the inner wall of the cavity 40. One end of the driving rod 31 passes through the movable hole 55 and is fixedly mounted with a connecting rod 41. A sliding sleeve 43 is slidably mounted in the mounting hole 52. A bristle groove is provided on the annular inner wall of the sliding sleeve 43. Multiple evenly arranged bristles 42 are fixedly mounted in the bristle groove. One end of the sliding sleeve 43 is aligned with the inner wall of the conical hole 51. One end of the sliding sleeve 43 is fixedly connected to the side of the connecting rod 41. The driving rod 31 is slidably connected to the inner wall of the movable hole 55. The movement of the L-shaped plate 34 causes the pull rod 30 to rotate. The rotation of the pull rod 30 pulls the drive rod 31 closer to the L-shaped plate 34. The movement of the drive rod 31 causes the connecting rod 41 and the sliding sleeve 43 to move. The movement of the sliding sleeve 43 causes the brush bristles 42 to move. When the brush bristles 42 contact the sensor 44, the sensor 44 can be cleaned by the brush bristles 42, making it easier to perform the next test.

[0029] like Figure 1 As shown, a handle 5 is fixedly installed on the top of the box 1, four casters 2 are fixedly installed on the bottom of the box 1, and a feed pipe 4 is fixedly installed on the top of the box 1 for feeding materials; the handle 5 and casters 2 make it easy to carry the box 1.

[0030] like Figure 8 As shown, the feed pipe 4 corresponds to the positions of the filter box 7 and the collection block 38. The side of the box body 1 and the partition plate 6 is fixedly installed with a sealing plate 45, which corresponds to the position of the mounting sleeve 8. The side of the sealing plate 45 has two rectangular holes and one clearance hole. The mounting sleeve 8 is rotatably installed in the clearance hole. The two vertically arranged filter boxes 7 are respectively located in the two rectangular holes. By setting the sealing plate 45, the left and right sides of the two vertically arranged filter boxes 7 can be separated, one side is used for filtration and the other side is used for cleaning.

[0031] like Figure 1 As shown, a maintenance door is installed on the side of the housing 1; the maintenance door facilitates the cleaning of impurities later. like Figure 6 As shown, multiple filter boxes 7 have a plurality of evenly spaced filter holes on their bottom inner walls, and the cross-section formed by the groove of the filter box 7 is an isosceles trapezoid. The filter holes are used to filter the soil. Because the cross-section formed by the groove of the filter box 7 is an isosceles trapezoid, impurities inside the filter box 7 will not fall out when the filter box 7 is flipped to a vertical position, thereby preventing impurities from falling into the conical hole 51.

[0032] This application also includes a power bank and a controller for controlling the motor.

[0033] The working principle and usage process of this invention are as follows: During use, soil is fed into the machine through the feed pipe 4, and the soil falls onto one of the filter boxes 7. At this time, the external motor 3 is started, and the output shaft of the external motor 3 rotates, driving the rotating shaft 20 and the intermediate gear 21 to rotate. The intermediate gear 21 drives the eccentric column 25 to rotate through a side gear 29. The eccentric column 25 rotates circumferentially, pressing against the inner wall of the slot 27. A gap remains between the top and bottom inner walls of the slot 27, causing the U-shaped plate 28 to move back and forth, which in turn causes the push rod 26 to move back and forth, bringing the push rod 26 closer to... When the extrusion plate 16 is pressed, it will drive the extrusion plate 16, rectangular rod 15 and filter box 7 to move. The two moving springs 14 will deform. When the push rod 26 moves away from the extrusion plate 16, the extrusion plate 16, rectangular rod 15 and filter box 7 will return to their original positions under the action of the two moving springs 14. This will cause the filter box 7 to move back and forth to screen the soil. Impurities are located on the filter box 7. The screened soil falls into the conical hole 51 through the filter box 7 and is located on the sensor 44. The soil can be detected by the sensor 44 and displayed by the detector 36. After the test is completed, if it is necessary to discharge, simply open the valve to discharge the soil. If it is necessary to collect, a collection bottle can be placed below the discharge pipe 37 for collection. Then, start the internal motor 48 to drive the small gear 50 to rotate counterclockwise. The rotation of the small gear 50 drives the large gear 49 to rotate clockwise, thereby driving the mounting sleeve 8 to rotate. The rotation of the mounting sleeve 8 drives the four rectangular sleeves 9 and the four filter boxes 7 to rotate, thereby causing the filter box 7 containing impurities to rotate 90 degrees. At this time, the filter box 7 at the bottom rotates to a horizontal state. When the mounting sleeve 8 rotates, the inclined inner wall of the right-angled triangular hole 46 will press the rotating wheel 47, thereby causing the rotating wheel 47 and the L-shaped mounting rod 35 to move away from the partition plate 6. The movement of the L-shaped mounting rod 35 drives the L-shaped plate 34 away from the partition plate 6. When the rotating wheel 47 separates from the right-angled triangular hole 46, the top of the L-shaped plate 34 is offset from the filter box 7, so as not to affect the rotation of the uppermost filter box 7 to a horizontal flipped state. Meanwhile, during the rotation of the mounting sleeve 8, the movement of the L-shaped plate 34 causes the two return springs 33 to deform. The movement of the L-shaped plate 34 drives the pull rod 30 to rotate. The rotation of the pull rod 30 pulls the driving rod 31 to move closer to the L-shaped plate 34. The movement of the driving rod 31 drives the connecting rod 41 and the sliding sleeve 43 to move. The movement of the sliding sleeve 43 drives the brush bristles 42 to move. When the brush bristles 42 contact the sensor 44, the sensor 44 can be cleaned by the brush bristles 42, making it easier to detect next time. When the uppermost mounting sleeve 8 rotates to the horizontal flip state, the vertical side of the other right-angled triangular hole 46 corresponds to the rotating wheel 47. Under the action of the two return springs 33, the sliding sleeve 43 and the L-shaped plate 34 return to their original state. Then, soil can be added for testing. After the test is completed, the operation is repeated so that the filter box 7, which initially contained impurities, rotates to a horizontal flipped state. Some impurities will fall off due to gravity. During the rotation of the middle gear 21, the side gear 29 will rotate. The rotation of the side gear 29 will drive the squeezing column 18 to rotate clockwise. The clockwise rotation of the squeezing column 18 will squeeze the pressure rod 17 and make it move downward. The downward movement of the pressure rod 17 will drive the rectangular sleeve 9, the rectangular rod 15, and the flipped filter box 7 to move downward. The four limit springs 13 will deform. When the squeezing column 18 separates from the pressure rod 17, the rectangular sleeve 9 will return to its original shape under the force of the four limit springs 13. This will cause the flipped filter box 7 to hit the L-shaped plate 34, which will vibrate the filter box 7 and cause the impurities stuck on the filter box 7 to fall off, making it easier for the next test. During the rotation of the four rectangular sleeves 9, when the positions of the extrusion plate 16 and the push rod 26 are not aligned, the push rod 26 will extrude the extrusion plate 16, causing the rectangular sleeve 9 to move along the direction of the limiting rod 11. The limiting spring 13 will deform, and during the back-and-forth movement of the push rod 26, the extrusion plate 16 and the push rod 26 will be misaligned. Under the action of the limiting spring 13, the extrusion plate 16 and the push rod 26 will be aligned. Similarly, when the positions of the pressure rod 17 and the extrusion column 18 are not aligned, the extrusion column 18 will extrude the pressure rod 17, causing the rectangular sleeve 9 to move along the direction of the limiting rod 11. The limiting spring 13 will deform, and during the rotation of the extrusion column 18, the pressure rod 17 will return to its original shape under the reaction force of the limiting spring 13.
