Description

Technical Field

[0001] The present invention relates to the technical field of garden soil detection, and specifically relates to a detector for detecting the quality of garden soil. Background Art

[0002] The construction of garden landscapes and the growth of garden plants are inseparable from the soil. Therefore, it is necessary to detect the garden soil. Reasonable detection of the garden soil can enable the administrator to more intuitively understand the soil fertility, pH value, and pollution situation, which is convenient for the administrator to formulate a more reasonable garden construction plan. When conducting soil detection, the pH value of the soil is an extremely important indicator. The pH value of the soil not only affects the growth of plants but also affects the soil structure. When detecting the pH value of the soil, a soil quality detector is required. When detecting the pH value of the soil, the soil sample and deionized water need to be mixed in a certain proportion (1:2.5 or 1:5). After mixing the sample and the liquid, a pH meter is used for detection. If the operator does not mix them enough during the mixing process, it will affect the final detection result of the pH meter. To overcome the above defects, in the prior art 1 (a Chinese patent application with the application number 202320637712.9 and the application date of March 28, 2023), a portable soil acidity detector is provided. It is provided with a stirring mechanism for mixing the solution in the container. At the same time, the entire detector integrates the detection part and the solution treatment part into one, which not only makes the operation more convenient, but also has a small volume and is easy to carry, making the detection result more accurate. In the prior art 2 (a Chinese patent application with the application number 202410655621.7 and the application date of May 24, 2024), a soil detection device and detection method for soil improvement are provided. It is provided with a rotating assembly. When the servo motor is started, the rotating shaft rotates, and then the U-shaped frame rotates. Cooperating with the top plate, the warehouse cover, the L-shaped frame, and the servo motor, the rotating rod and the driving gear rotate. Cooperating with the rotating cylinder, the driven gear, and the large ring block, the large stirring paddle and the large rack fully mix and stir the soil sample to be detected and the detection liquid agent inside the dissolution warehouse, making the detection result more accurate. In the prior art 3 (a Chinese patent application with the application number 202323122492.5 and the application date of November 20, 2023), a soil acid-base detection device is provided. During its use, the soil sample and water in the detection beaker are stirred and mixed by a first rotating rod that can move up and down and multiple stirring cutters. The stirring and mixing will be relatively uniform, and it can effectively reduce the time required for mixing, improve the mixing efficiency, and further improve the efficiency of soil acid-base detection. At the same time, it can effectively reduce the workload of experimental personnel and has strong practicability.

[0003] During the detection process, the mixing depth of the sample and the reagent is of utmost importance. However, the detection device in the above application does not have a multiple mixing structure during use, and the mixing depth is still insufficient. Therefore, when the pH meter is used for detection, the detection result will still be biased, which will affect the operator's judgment of the detection result and bring unnecessary trouble to the soil detection process. Summary of the Invention

[0004] The purpose of the present invention is to provide a detector for detecting the quality of garden soil, so as to solve the problem that in the above background technology, during use, it does not have a multiple mixing structure, the mixing depth is still insufficient, and when the pH meter is used for detection, the detection result will still be biased, which will affect the operator's judgment of the detection result and bring unnecessary trouble to the soil detection process.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A detector for detecting the quality of garden soil includes a detection bottle. The surface of the detection bottle is movably connected with a bottle cap, and a pH meter is arranged inside the bottle cap. A liquid adding pipe is fixedly connected to the surface of the bottle cap, and a pipe cap is movably arranged on the surface of the liquid adding pipe. The inside of the bottle cap is connected with a working rod through a reciprocating component, a mixing blade is fixedly connected to the surface of the working rod, and a lower connecting rod is fixedly connected to the inner wall of the bottle cap. The inside of the bottle cap is connected with a connecting plate through a lifting component, the connecting plate is connected with a cleaning plate through a swinging component, and a brush is arranged on the surface of the cleaning plate. An auxiliary block is fixedly connected to the inner wall of the cleaning plate.

[0006] Preferably, the reciprocating component includes a pressing rod slidably arranged inside the bottle cap. The upper end of the pressing rod is located outside the bottle cap, and a pressing plate is fixedly connected to the upper end of the pressing rod. The pressing rods are symmetrically distributed on both sides of the pressing plate.

[0007] Preferably, a stress plate is fixedly connected to the surface of the working rod. The stress plate is spiral, and the stress plates correspond to the pressing rods one by one. The upper surface of the stress plate is in contact with the lower surface of the pressing rod. A partition plate is fixedly connected to the surface of the pressing rod, and the partition plate is located below the bottle cap.

[0008] Preferably, the mixing blades are equally spaced on the surface of the working rod. A torsion spring for elastic reset is fixedly connected to the surface of the working rod, and the other side of the torsion spring is fixedly connected to the inner wall of the bottle cap.

[0009] Preferably, the lifting component includes a connecting rod fixedly connected to the surface of the working rod, and a first magnet is fixedly connected to the upper surface of the connecting rod.

[0010] Preferably, the lower connecting rod penetrates through the inside of the connecting plate, and the front view of the connecting plate is an inverted "L" structure. Moreover, a second magnet is fixedly connected to the lower surface of the connecting plate, and the position of the lower connecting rod below the connecting plate is convex.

[0011] Preferably, the magnetic pole on the lower surface of the second magnet is the same as the magnetic pole on the upper surface of the first magnet. An auxiliary plate is fixedly connected to the surface of the lower connecting rod, and the auxiliary plate is located above the connecting plate. Moreover, a connecting spring is fixedly connected between the lower surface of the auxiliary plate and the connecting plate.

[0012] Preferably, the swinging assembly includes an external connecting block fixedly connected to the surface of the connecting plate. A limiting rod is fixedly connected to the inner wall of the cleaning plate, and the limiting rod penetrates through the inside of the external connecting block. Moreover, a deep groove is formed on the inner wall of the cleaning plate. A pushing rod is fixedly connected to the lower surface of the left lower connecting rod, and the left view of the pushing rod is an inverted "L" structure.

[0013] Preferably, the end of the pushing rod is located inside the deep groove. The external connecting blocks are symmetrically distributed on both sides of the cleaning plate. Moreover, a reset spring is fixedly connected to the surface of the left external connecting block, and the other side of the reset spring is fixedly connected to the inner wall of the cleaning plate. A stress rod is fixedly connected to the inner wall of the deep groove, and the stress rods are distributed in a staggered manner inside the deep groove.

[0014] Preferably, the cleaning plate is circular in structure. The auxiliary blocks are evenly distributed at equal angles on the inner wall of the cleaning plate, and both the upper and lower sides of the auxiliary blocks are inclined.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: With a novel structural design, by means of the provided reciprocating mechanism, the working rod and the mixing blades can rotate reciprocally inside the detection bottle. Compared with the unidirectional rotation of the mixing blades, the reciprocally rotating mixing blades can better mix the sample and the reagent, making the final detection result of the pH meter more accurate and the data more precise. When the working rod rotates, the connecting plate and the cleaning plate will move vertically. At this time, the auxiliary blocks on the inner wall of the cleaning plate also play a role in turning over the material, that is, the cleaning plate and the auxiliary blocks play a role in side-assisted stirring, enabling the detection bottle to have a multi-mixing structure. Finally, when the pH meter is detecting, the detection result is more accurate, no detection deviation will occur, the trouble of soil detection is reduced, and the work efficiency is improved. The specific content is as follows: When in use, for the detector for detecting the quality of garden soil, pour the soil sample and reagent into the detection bottle, and then screw on the bottle cap. At this time, the pressing plate on the surface of the bottle cap can be pressed, and then the pressing rod will push the stress plate. At this time, under the action of the pressing rod and the torsion spring, the stress plate, the working rod and the mixing blade will rotate reciprocally inside the bottle cap. Compared with the unidirectional rotation of the mixing blade, the reciprocally rotating mixing blade can better mix the sample and the reagent, making the detection result of the final pH meter more accurate.

[0016] Furthermore, the working rod and the mixing blade are symmetrically distributed on both sides of the bottle cap, which can better mix the materials and improve the working efficiency.

[0017] When the working rod of the detector for detecting the quality of garden soil rotates, it will drive the connecting rod to rotate synchronously. At this time, the first magnet on the surface of the connecting rod will intermittently approach the second magnet on the lower surface of the connecting plate. As a result, the connecting plate will be intermittently subjected to the mutually repulsive magnetic force. At this time, under the action of the mutually repulsive magnetic force, the auxiliary plate and the connecting spring, the connecting plate will perform reciprocating linear motion in the vertical direction. The connecting plate will drive the cleaning plate to move synchronously through the external block and the limiting rod. At this time, the cleaning plate will turn the mixed materials through the auxiliary block on its inner wall. At this time, the auxiliary block plays a role in side auxiliary stirring, making the detection bottle have a multi-mixing structure, and finally making the detection result of the pH meter more accurate when detecting.

[0018] Furthermore, the auxiliary blocks are equidistantly distributed on the inner wall of the cleaning plate, optimizing the effect of turning the materials.

[0019] When the cleaning plate of the detector for detecting the quality of garden soil rises, it will drive the stress rod inside the deep groove to move synchronously. Then, the push rod on the lower surface of the left lower connecting rod will intermittently push the stress rod. At this time, under the action of the thrust, the limiting rod, the external block and the return spring, the stress rod and the cleaning plate are in a state of reciprocating rotation. As a result, the auxiliary block on the inner wall of the cleaning plate can better turn the materials, optimizing the mixing effect.

[0020] Furthermore, when the cleaning plate moves, it will clean the inner wall of the detection bottle through the brush on its surface. As a result, after the detection is completed, the operator can clean the detection bottle more conveniently. After removing the bottle cap, there are no other parts inside the detection bottle, and the cleaning process is more convenient. Then, the operator only needs to clean the bottle cap.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides the following technical solution: A detector for detecting the quality of garden soil.

[0025] Embodiment 1: By providing a reciprocally rotatable working rod 5 and mixing blade 6, the soil sample and the reagent can be deeply mixed, such as Figures 1 - 5As shown in the figure, it includes a detection bottle 1, a bottle cap 2 is movably connected to the surface of the detection bottle 1, a pH meter 3 is arranged inside the bottle cap 2, a liquid adding tube 4 is fixedly connected to the surface of the bottle cap 2, and a tube cap 27 is movably arranged on the surface of the liquid adding tube 4; a working rod 5 is connected to the inside of the bottle cap 2 through a reciprocating assembly, a mixing blade 6 is fixedly connected to the surface of the working rod 5, and a lower connecting rod 15 is fixedly connected to the inner wall of the bottle cap 2; the reciprocating assembly includes a pressing rod 8 slidably arranged inside the bottle cap 2, the upper end of the pressing rod 8 is located outside the bottle cap 2, a pressing plate 7 is fixedly connected to the upper end of the pressing rod 8, and the pressing rods 8 are symmetrically distributed on both sides of the pressing plate 7.

[0026] A stress plate 9 is fixedly connected to the surface of the working rod 5, the stress plate 9 is spiral, the stress plates 9 correspond to the pressing rods 8 one by one, the upper surface of the stress plate 9 is attached to the lower surface of the pressing rod 8, a partition plate 10 is fixedly connected to the surface of the pressing rod 8, the partition plate 10 is located below the bottle cap 2, the mixing blades 6 are equidistantly distributed on the surface of the working rod 5, a torsion spring 11 that plays an elastic reset role is fixedly connected to the surface of the working rod 5, and the other side of the torsion spring 11 is fixedly connected to the inner wall of the bottle cap 2.

[0027] When in use, pour the soil sample and the reagent into the detection bottle 1, and then rotate and screw on the bottle cap 2. At this time, the pressing plate 7 on the surface of the bottle cap 2 can be pressed, and then the pressing rod 8 will push the stress plate 9. When the stress plate 9 is pushed, the stress plate 9 drives the working rod 5 and the mixing blade 6 to rotate. At this time, the torsion spring 11 is stretched. After releasing the pressing plate 7, the stress plate 9, the working rod 5 and the mixing blade 6 rotate back under the action of the torsion spring 11, and then the pressing rod 8 and the pressing plate 7 are pushed back to their original positions. Repeating the above process, the working rod 5 and the mixing blade 6 are in a reciprocating rotation state. At this time, compared with the unidirectional rotation of the mixing blade 6, the reciprocatingly rotating mixing blade 6 can better mix the sample and the reagent, making the final detection result of the pH meter 3 more accurate. The working rod 5 and the mixing blade 6 are symmetrically distributed on both sides of the bottle cap 2, which can better mix the materials and improve the working efficiency.

[0028] Embodiment 2: Different from Embodiment 1, by providing the cleaning plate 14 and the auxiliary block 25 on the inner wall of the cleaning plate 14, it plays a role in laterally assisting in turning over and mixing the materials, as Figures 6 - 7 shown, a connecting plate 16 is connected to the inside of the bottle cap 2 through a lifting assembly, a cleaning plate 14 is connected to the surface of the connecting plate 16 through a swinging assembly, and a brush is arranged on the surface of the cleaning plate 14; an auxiliary block 25 is fixedly connected to the inner wall of the cleaning plate 14.

[0029] The lifting component includes a connecting rod 12 fixedly connected to the surface of the working rod 5. A first magnet 13 is fixedly connected to the upper surface of the connecting rod 12. The lower connecting rod 15 passes through the inside of the connecting plate 16. The front view of the connecting plate 16 is an inverted "L" structure. A second magnet 19 is fixedly connected to the lower surface of the connecting plate 16. The position of the lower connecting rod 15 below the connecting plate 16 is convex. The magnetic pole on the lower surface of the second magnet 19 is the same as the magnetic pole on the upper surface of the first magnet 13. An auxiliary plate 17 is fixedly connected to the surface of the lower connecting rod 15. The auxiliary plate 17 is located above the connecting plate 16. A connecting spring 18 is fixedly connected between the lower surface of the auxiliary plate 17 and the connecting plate 16.

[0030] When the working rod 5 rotates, it will drive the connecting rod 12 to rotate synchronously. At this time, the first magnet 13 on the surface of the connecting rod 12 will intermittently approach the second magnet 19 on the lower surface of the connecting plate 16. When the first magnet 13 approaches the second magnet 19, under the action of the repulsive magnetic force, the connecting plate 16 slides upward on the surface of the lower connecting rod 15. At this time, the auxiliary plate 17 will compress the connecting spring 18. When the first magnet 13 moves away from the second magnet 19, the repulsive magnetic force acting on the connecting plate 16 decreases. At this time, the connecting plate 16 descends under the action of the connecting spring 18. Repeating the above process, the connecting plate 16 makes a reciprocating linear motion in the vertical direction. The connecting plate 16 will drive the cleaning plate 14 to move synchronously through the external connecting block 20 and the limiting rod 21. At this time, the cleaning plate 14 will turn the mixed material through the auxiliary block 25 on its inner wall. At this time, the auxiliary block 25 plays a role in side auxiliary stirring, making the detection bottle 1 have a multi-mixing structure, and finally making the detection result of the pH meter 3 more accurate when detecting.

[0031] Embodiment 3: Different from Embodiment 2, by providing a swinging component, the cleaning plate 14 can be in a rotating state during the rising and falling processes, optimizing the mixing effect and improving the accuracy of the detection result. As Figures 8 - 10 shown, the swinging component includes an external connecting block 20 fixedly connected to the surface of the connecting plate 16. A limiting rod 21 is fixedly connected to the inner wall of the cleaning plate 14. The limiting rod 21 passes through the inside of the external connecting block 20. A deep groove 26 is formed on the inner wall of the cleaning plate 14. A push rod 23 is fixedly connected to the lower surface of the left lower connecting rod 15. The left view of the push rod 23 is an inverted "L" structure.

[0032] The end of the push rod 23 is located inside the deep groove 26. The external connection blocks 20 are symmetrically distributed on both sides of the cleaning plate 14. A return spring 22 is fixedly connected to the surface of the left external connection block 20, and the other side of the return spring 22 is fixedly connected to the inner wall of the cleaning plate 14. A stress rod 24 is fixedly connected to the inner wall of the deep groove 26, and the stress rods 24 are staggeredly distributed inside the deep groove 26. The cleaning plate 14 is of a circular structure. The auxiliary blocks 25 are equally angularly distributed on the inner wall of the cleaning plate 14, and both the upper and lower sides of the auxiliary blocks 25 are inclined.

[0033] During the upward or downward movement of the cleaning plate 14, it will drive the stress rods 24 inside the deep groove 26 to move synchronously. Consequently, the push rod 23 on the lower surface of the left lower connecting rod 15 will intermittently push the stress rods 24. When the stress rods 24 are pushed, the cleaning plate 14 will rotate while the external connection blocks 20 remain stationary. As a result, the return spring 22 is compressed. When the stress rods 24 continue to move until they are no longer in contact with the push rod 23, the cleaning plate 14 rotates back under the action of the return spring 22. Repeating the above process, the stress rods 24 and the cleaning plate 14 are in a reciprocating rotation state under the action of the thrust force, the limiting rods 21, the external connection blocks 20, and the return spring 22. Thus, the auxiliary blocks 25 on the inner wall of the cleaning plate 14 can better turn over the materials, optimizing the mixing effect.

[0034] Embodiment 4: Different from Embodiment 3, by providing the cleaning plate 14, the inner wall of the test bottle 1 can be cleaned. While the cleaning plate 14 moves, it will clean the inner wall of the test bottle 1 through the brushes on its surface. Consequently, after the test is completed, the operator can clean the test bottle 1 more conveniently. At the same time, after removing the bottle cap 2, there are no other parts inside the test bottle 1, making the cleaning process more convenient. Then, the operator only needs to clean the bottle cap 2.

[0035] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
