Description

Technical Field

[0001] The present invention belongs to the technical field of soil detection, and in particular relates to a soil detection probe. Background Art

[0002] Soil testing is crucial in fields such as agriculture and environmental protection. Its accuracy and efficiency are directly related to scientific assessments of the soil environment and the effectiveness of subsequent management measures. However, traditional soil testing tools, particularly soil testing probes, have exposed significant shortcomings in practical applications, affecting both accuracy and efficiency.

[0003] After traditional soil detection probes are inserted into the soil, it is often difficult to control the time to pull them out, which affects the accuracy of the information they extract from the soil. At the same time, in actual use, the detection head of the detection rod is easily contaminated with mud after being inserted into the soil, which requires frequent cleaning and maintenance of the probe during use, which not only increases the workload but may also reduce work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a soil detection probe to solve the problems mentioned in the background technology.

The two cams are engaged with each other, and a control component for controlling the rotation of the rotating shaft is installed on the lower side of the shell, and a driving component for controlling the up and down movement of the vertical rod is installed on the inner side of the shell. A liquid tank is also fixed to the inner wall of the shell, and a filling port connected to the interior of the liquid tank is installed on the side of the shell. A cover matching the filling port is provided on the outer side of the filling port. A circular ring is fixed on the lower side of the cleaning brush group, and a plurality of circumferentially distributed pressurized nozzles are installed on the upper side of the circular ring. The pressurized nozzles are connected to the liquid tank pipeline, and a pressurizing component for pressurizing the inside of the liquid tank is provided on the inner side of the shell;

[0007] The control assembly includes a spur gear, which is fixed concentrically with one of the rotating shafts, a sliding rod is installed on the inner side of the shell for sliding up and down, a plurality of limit plates are installed on the upper side of the slide rod at even intervals, the spur gear is transmission-connected to the limit plate, a C-shaped groove is provided on the side of the shell, a push rod is horizontally fixed on the upper side of the slide rod, the push rod matches the C-shaped groove, a baffle is provided on the side of the C-shaped groove and is fixed to the inner wall of the shell, and a return spring is fixed between the baffle and the push rod.

[0009] The pressurizing assembly includes an air pump and an air pump rod. The air pump is fixedly connected to the outer shell. A crankshaft rod connected to it is rotatably installed on the side of the upper sprocket. A connecting rod is eccentrically connected to the upper side of the crankshaft rod. The other end of the connecting rod is connected to the air pump rod. The output end of the air pump is connected to the upper pipeline inside the liquid tank. An air inlet hole is opened on the side wall of the outer shell.

[0010] A normally open push switch is fixed inside the housing, the normally open push switch matches the C-shaped groove, and the normally open push switch is electrically connected to the control panel.

[0011] A rubber sealing ring matching the vertical rod is fixedly installed at the connection portion between the shell and the vertical rod.

[0012] A through groove communicating with the liquid tank is vertically provided on the outer side surface, and a transparent observation window is installed on the inner side of the through groove.

[0013] The upper side of the vertical rod extends out of the top of the shell, and a top plate is fixedly installed on the top of the vertical rod.

[0014] Support seats are evenly fixed on the bottom of the shell.

[0015] The control component can retract or horizontally open the brush head when needed, which is convenient for controlling the use of the cleaning brush group. The driving component is used to control the up and down movement of the vertical rod and the detection probe.

While making the control component simple to operate, it can also effectively improve the stability of the cleaning brush group, reduce the workload of detecting probe cleaning, and improve detection efficiency.

[0016] The design of driving the vertical rod up and down through the sprocket, chain, straight notch and control rod allows the motor to accurately control the vertical position of the vertical rod as needed. It also makes the structure of the drive component simple and compact, and has a long operating range, which helps to reduce the overall size of the equipment. At the same time, the chain drive system composed of sprockets and chains is relatively simple to maintain, can more effectively transmit power, and reduce energy loss.

[0017] The air pump, air rod, crankshaft and connecting rod enable the pressure component to be linked to the upper sprocket when the drive component is working, converting the circular motion of the sprocket into the up and down reciprocating motion of the air rod, thereby being used to inflate and pressurize the interior of the liquid tank, so that the cleaning fluid or lubricant can be sprayed out smoothly, achieving synchronous control while reducing the power source of the equipment, thereby helping to reduce the production cost of the equipment;

[0018] The normally open push switch matched with the C-shaped groove enables the push rod to control the operation of the cleaning brush group, and can synchronously control the drive component to drive the vertical rod up and down, so as to control the brush head to clean the detection probe up and down, thereby improving the convenience of using the equipment;

[0019] The use of rubber sealing rings ensures the sealing of the vertical rod when it moves up and down, prevents soil or moisture from entering the inside of the casing, and improves the durability of the equipment. The transparent observation window allows the user to observe the remaining amount of liquid in the liquid tank at any time, which is convenient for timely refilling and reduces the workload of maintenance. The vertical rod extending from the top of the casing and the design of the top plate allow the user to directly apply pressure to the top plate, thereby directly driving the detection probe to be inserted into the inside of the soil to be inspected, thereby reducing the working intensity of the drive component and helping to extend the service life of the equipment. The support seat can increase the contact area between the bottom of the casing and the soil, so that the equipment can avoid sinking as a whole when the detection probe is pulled out upwards, while also increasing the stability of the equipment and making it more convenient to use.

DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-7As shown, a soil detection probe includes a shell 1, a control panel 2 is installed on the outside of the shell 1, and a timing module is built into the control panel 2. A vertical rod 3 is installed on the inside of the shell 1 for sliding up and down. A detection probe 4 electrically connected to the control panel 2 is fixed on the lower side of the vertical rod 3. A group of cleaning brushes are installed in the four directions of the front, back, left and right of the detection probe 4. The cleaning brush group includes a rotating shaft 5, which is rotatably installed on the lower side of the inner part of the shell 1. A brush head 6 is fixed near the inner side of the rotating shaft 5. Bevel gears 7 are concentrically fixed at both ends of the rotating shaft 5. Two adjacent bevel gears 7 on different rotating shafts 5 They are meshed with each other. A control component for controlling the rotation of the rotating shaft 5 is installed on the lower side of the shell 1. A driving component for controlling the up and down movement of the vertical rod 3 is installed on the inner side of the shell 1. A liquid tank 8 is also fixed to the inner wall of the shell 1. A filling port 9 communicating with the interior of the liquid tank 8 is installed on the side of the shell 1. A cover 10 matching the filling port 9 is provided on the outer side of the filling port 9. A circular ring 11 is fixed to the lower side of the cleaning brush group. A plurality of circumferentially distributed pressurized nozzles 12 are installed on the upper side of the circular ring 11. The pressurized nozzles 12 are connected to the pipeline of the liquid tank 8. A pressurizing component for pressurizing the inside of the liquid tank 8 is provided on the inner side of the shell 1.

[0031] The control component includes a spur gear 13, which is fixed concentrically with one of the rotating shafts 5. A slide rod 14 is installed on the inner side of the shell 1 for sliding up and down. A plurality of limit plates 15 are installed on the upper side of the slide rod 14 at even intervals. The spur gear 13 is transmission-connected to the limit plates 15. A C-shaped groove 16 is provided on the side of the shell 1. A push rod 17 is horizontally fixed on the upper side of the slide rod 14. The push rod 17 matches the C-shaped groove 16. A baffle 18 fixed to the inner wall of the shell 1 is provided on the side of the C-shaped groove 16. A return spring 19 is fixed between the baffle 18 and the push rod 17.

[0032] In the present invention, the shell 1 serves as the main structure of the entire detection probe, protecting the internal components and serving as a support for soil detection. The control panel 2 includes a timing module for setting parameters such as the diving depth and residence time of the detection probe 4. The detection probe 4 is used to actually detect the composition or properties of the soil and is electrically connected to the control panel 2 to transmit data. The cleaning brush group consists of a rotating shaft 5, a bevel gear 7 and a brush head 6. The synchronous rotation in four directions is achieved by the engagement of adjacent bevel gears 7. A pressurized nozzle is a nozzle that does not spray water when there is no pressure and sprays water when pressure is applied.

[0033] The control component can retract or horizontally open the brush head 6 when needed, which is convenient for controlling the use of the cleaning brush group. The driving component is used to control the up and down movement of the vertical rod 3 and the detection probe 4. In conjunction with the control panel 2, the detection probe 4 can be pulled out when and how deep it is inserted into the soil. The brush head 6 can move back and forth to clean the soil residue on the detection probe 4, thereby reducing the detection error of the equipment. The inside of the liquid tank 8 can hold cleaning liquid. The multiple pressurized nozzles distributed around the periphery can cooperate with the pressurized component to spray cleaning liquid on the detection probe 4 when cleaning, so that the detection probe 4 can be brushed clean. The push rod 17 can switch positions at both ends of the C-shaped groove 16, and can effectively limit the slide rod 14 in conjunction with the return spring 19. The cooperation of the multiple spaced limit plates 15 and the spur gear 13 ensures that when the push rod 17 is toggled inside the C-shaped groove 16, the limit plate 15 can always abut against the spur gear 13, thereby effectively limiting the position of the brush head 6. While making the control component simple to operate, it can also effectively improve the stability of the cleaning brush group, reduce the cleaning workload of the detection probe 4, and improve the detection efficiency.

A motor 25 electrically connected to the control panel 2 is fixed on the side of the sprocket 20 on the lower side, and the output end of the motor 25 is transmission-connected to the sprocket 20 on the lower side.

[0035] The design of driving the vertical rod 3 to move up and down through the sprocket 20, chain 21, straight slot 23 and control rod 24 allows the motor 25 to accurately control the up and down position of the vertical rod 3 as needed, and also makes the structure of the drive component simple and compact, and the operating range is long, which helps to reduce the overall size of the equipment. At the same time, the chain transmission system composed of the sprocket 20 and chain 21 is relatively simple to maintain, can more effectively transmit power, and reduce energy loss.
