Description

Technical Field

[0001] This invention relates to the technical field of paddy field mud layer thickness measurement equipment, specifically a paddy field mud layer thickness measurement device with a detection sensor structure. Background Technology

[0002] The equipment for measuring the thickness of the mud layer in paddy field soil mainly refers to the instrument used to measure the thickness of the mud layer in paddy field soil. The measurement of the thickness of the mud layer in paddy field soil refers to determining the vertical depth of the mud layer (humus layer, leaching layer and parent material layer) through professional tools or methods, thereby assessing soil fertility and tillage performance.

[0003] Existing Chinese patent CN102147225A, published on August 10, 2011, discloses a multifunctional soil thickness measuring instrument, which includes a base, a retractable observation tube, and a measuring scale. The bottom surface of the base is flat, and a vertical through hole is provided on the base. Both ends of the observation tube are closed, and the lower end of the observation tube is fixedly installed in the through hole. The upper end of the scale is located inside the observation tube, and the lower end extends vertically out from the lower end of the observation tube.

[0004] However, in actual use, the above-mentioned device requires a retractable observation tube and measuring scale for measurement. The tube is inserted into the muddy soil layer at the foot of the paddy field for measurement. When the measurement is confirmed, personnel need to bend over and check it with their naked eyes. The device cannot be effectively automated. When measuring at multiple points, it is laborious and inefficient for personnel.

[0005] Therefore, it is necessary to provide a novel device for measuring the thickness of the muddy soil layer at the foot of paddy fields with a detection sensor structure to solve the above-mentioned technical problems. Summary of the Invention

[0012] Furthermore, the lifting and measuring mechanism includes a measuring and mounting arm plate, which is welded to the hollow upper body. A linear screw body with a dustproof folded cloth is installed in the front groove of the measuring and mounting arm plate by screws. A screw motor is fixed to the upper end of the linear screw body with a dustproof folded cloth, and a screw slider is installed at the front end of the linear screw body with a dustproof folded cloth.

[0013] Furthermore, the spray rinsing mechanism includes a hollow spray hood, which is fixedly connected to the lower end of the measuring mounting arm plate.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-8 The present invention provides a technical solution: a device for measuring the thickness of the mud layer in paddy field mud foot soil with a detection sensor structure, including an upper body for measuring the thickness of the mud layer in paddy field mud foot soil, a lower body for measuring the thickness of the mud layer in paddy field mud foot soil, a lifting and measuring mechanism, a spraying and rinsing mechanism, and an infrared sensing and measuring mechanism.

[0022] The lower body of the paddy field mud layer thickness measuring machine is welded to the lower end of the upper body of the paddy field mud layer thickness measuring machine, allowing for stable installation. The lower body can slide and move through the plowed paddy field. The upper body includes a hollow upper body 8, inside which a rechargeable battery is installed with screws. The rechargeable battery can be charged and discharged. A control panel 7 is fixedly attached to a groove at the upper end of the hollow upper body 8 for easy operation. The control panel 7 and the rechargeable battery are electrically connected via a connecting wire for effective power supply. A push handle 81 is fixedly attached to the rear end of the hollow upper body 8 for easy gripping and pushing. Inspection panels are installed on the inner sides of both ends of the hollow upper body 8 with screws, allowing for easy access and maintenance of the internal components using tools.

[0023] The measuring device for measuring the thickness of the muddy soil layer in paddy fields includes a hollow base shell 2 and a pneumatic sliding mechanism. A cross-shaped smooth sleeve 21 is movably installed in the center of the hollow base shell 2. When exposed, the cross-shaped smooth sleeve 21 can contact the soil in the paddy field. The bottom of the cross-shaped smooth sleeve 21 is smooth, effectively reducing friction during pushing, thus allowing for stable pushing. Universal wheel storage slots 28 are provided at the four corners of the lower end of the hollow base shell 2 for storage. A movable lifting and storage mechanism is installed at the upper end of the hollow base shell 2. When moving on land, the movable lifting and storage mechanism can be exposed on the hollow base shell 2 and then pushed for movement. When moving in paddy fields, it can be stored in the hollow base shell 2, allowing for pushing using the exposed cross-shaped smooth sleeve 21. This facilitates the movement of personnel for multi-point measurements, making measurement movement more efficient. The movable lifting and storage mechanism includes a double-hole movable panel 13. Universal wheel mounting columns 11 are welded to the four corners of the lower end of the double-hole movable panel 13. When the double-hole movable panel 13 is raised or lowered, it can be positioned and raised via the four universal wheel mounting columns 11, making the raising and lowering more stable. The lower end of the universal wheel mounting columns 11 passes through the universal wheel storage groove 28 and is rotatably mounted with a swivel universal wheel 1. The swivel universal wheel 1 at the lower end of the universal wheel mounting columns 11 allows for movement and turning on the road surface. Movable lifting mechanisms are welded to the middle of both sides of the lower end of the double-hole movable panel 13. The movable lifting rod 15 can drive the double-hole movable panel 13 to rise and fall when it is raised and lowered. The lower end of the movable lifting rod 15 is fixedly connected to the first coupling 14. The movable lifting rod 15 can be raised and lowered through the raising and lowering of the first coupling 14. The lower end of the first coupling 14 is fixedly connected to the first electric telescopic cylinder 12. When the telescopic rod of the first electric telescopic cylinder 12 is raised and lowered, it can drive the first coupling 14 to rise and fall. The first electric telescopic cylinder 12 is installed on the hollow base shell 2 by screws. The first electric telescopic cylinder 12 can stably extend and retract on the hollow base shell 2. The pneumatic sliding mechanism includes an air pump 22, which can be stably mounted on the hollow base housing 2 using screws. An air supply bend 23 is screwed onto the exhaust end of the air pump 22, supplying air to the air supply bend 23. The other end of the air supply bend 23 passes through the hollow base housing 2 and is fixedly connected to an inflatable airbag 24. The air supply bend 23 can stably inflate the inflatable airbag 24 on the hollow base housing 2. A positioning moving plate 25 is fixedly connected to the lower end of the inflatable airbag 24. When the inflatable airbag 24 is inflated, it expands, causing the positioning moving plate 25 to move downwards. The lower end of the positioning moving plate 25 is fixedly connected to the cross-shaped smooth sleeve 21. The cross-shaped smooth sleeve 21 can be exposed, facilitating contact and sliding with the paddy field soil. Four symmetrical positioning vertical rods 27 are sleeved on the inner sides of both ends of the positioning moving plate 25. The positioning vertical rods 27 are welded to the inner wall of the hollow base shell 2. The positioning moving plate 25 can be positioned and moved on the four fixed positioning vertical rods 27 inside the hollow base shell 2. A resisting spring 26 is fixed between the hollow base shell 2 and the positioning moving plate 25. When the positioning moving plate 25 moves downward, it can cause the resisting spring 26 to deform and extend. When the expansion resistance of the inflatable airbag 24 disappears, the resisting spring 26 can pull the positioning moving plate 25 to deform and return to its original position inside the hollow base shell 2.

[0024] Example 2 like Figure 1 , Figure 6 , Figure 7 and Figure 8The lifting and measuring mechanism is welded to the inner front end of the upper body of the paddy field mud layer thickness measuring machine, allowing for stable installation. The lifting and measuring mechanism can be raised and lowered during measurement. The lifting and measuring mechanism includes a measuring mounting arm plate 53, with a groove on the inner front end for limiting installation. The measuring mounting arm plate 53 is welded to the hollow upper body 8 for stable installation. A linear screw body 5 with a dustproof folded cloth is installed in the groove at the front end of the measuring mounting arm plate 53 via screws. The dustproof folded cloth on the inner side of the linear screw body 5 effectively prevents external soil from entering, effectively protecting the dustproof folded cloth. The dustproof folding cloth linear screw machine body 5 has a screw motor 51 fixedly connected to the upper end of the screw motor 5. When the output shaft of the screw motor 51 rotates, it can drive the coupling to rotate. The coupling can drive the internal screw of the dustproof folding cloth linear screw machine body 5 to rotate in both directions. The front end of the dustproof folding cloth linear screw machine body 5 is equipped with a screw slider 52. When the internal screw of the dustproof folding cloth linear screw machine body 5 rotates in both directions, it can drive the screw slider 52 to rise and fall. The screw slider 52 can drive the infrared sensing measurement mechanism to rise and fall, which can measure the thickness of the mud layer of paddy field mud.

[0025] The infrared sensing measurement mechanism is mounted on the movable end of the lifting measurement mechanism with screws and can be installed and removed using tools. The infrared sensing measurement mechanism can measure the thickness of the mud layer in paddy field mud. The mechanism includes a right-angle mounting plate 44, which is mounted on a lead screw slider 52 with screws. The lead screw slider 52 can change the position of the right-angle mounting plate 44 during lifting and lowering. A positioning shaft 43 is welded to the lower end of the right-angle mounting plate 44, which can drive the positioning shaft 43 to lift and lower. An infrared sensor 4 is mounted on the outer side of the positioning shaft 43 on the right-angle mounting plate 44 with screws. The infrared sensor 4 emits infrared light for distance detection. A contact sensing component is threaded to the lower circumference of the positioning shaft 43. The contact sensing component can move downwards during descent of the positioning shaft 43. The device is lowered and inserted into the muddy soil layer at the foot of the paddy field. When the contact sensing component is blocked by pressure, the surface has reached the bottom. A movable sensing disc 41 is sleeved around the periphery of the positioning shaft 43. Due to the obstruction of the muddy soil layer at the foot of the paddy field, the movable sensing disc 41 can change its height on the positioning shaft 43. Then the infrared sensor 4 can sense the distance between them. By subtracting the sensing distance during measurement from the original detection distance, the depth data of the muddy soil layer at the foot of the paddy field can be directly obtained, making the detection more convenient and efficient. Temperature and humidity sensors 45 and pH sensors 46 are symmetrically installed on both sides of the lower end of the movable sensing disc 41. The temperature and humidity sensors 45 and pH sensors 46 at the lower end of the movable sensing disc 41 can effectively sense the temperature, humidity and pH data of the soil, making the overall detection more comprehensive and efficient. Infrared sensor 4, temperature and humidity sensor 45, and pH sensor 46 are electrically connected to control panel 7 via connecting cables, and can be effectively controlled through control panel 7.

[0026] The contact sensing component includes a hollow pressure plate 42. A pressure sensor 421 is sleeved on the inner side of the lower end of the hollow pressure plate 42. When the hollow pressure plate 42 moves the pressure sensor 421 downward and encounters an obstruction, the pressure sensor 421 will be subjected to obstruction pressure. The pressure sensor 421 can then transmit data signals to the control panel 7. When the control panel 7 receives the data, it stops the rotation of the lead screw motor 51. A data cable source 423 is fixedly connected to the upper end of the pressure sensor 421. The pressure sensor 421 can effectively transmit data signals through the data cable source 423. An assembly screw hole 422 is provided on the inner side of the upper end of the hollow pressure plate 42 for limited installation. The hollow pressure plate 42 is threadedly connected to the positioning shaft 43 through the assembly screw hole 422 for easy installation and removal by personnel. The data cable source 423 is electrically connected to the control panel 7 through a connecting wire, which can effectively transmit electrical signals.

[0027] Example 3 like Figure 1 and Figure 6 The spray rinsing mechanism is installed and connected to the lower rear side of the lifting and measuring mechanism, allowing for stable placement and spray rinsing. The spray rinsing mechanism includes a hollow spray hood 3, which is fixedly attached to the lower end of the measuring mounting arm plate 53 for stable installation. A perforated panel 31 is fixedly attached to the inner front side of the hollow spray hood 3, allowing water inside the hood 3 to be effectively sprayed out through the mesh of the perforated panel 31. The water sprayed from the perforated panel 31 can rinse the lower part of the positioning shaft 43. A rubber hose 62 is fixedly connected to the rear end of the hollow spray hood 3, allowing the hood 3 to receive water from the rubber hose 62. An output right-angle pipe 61 is installed at the other end of the rubber hose 62 via screws, allowing the rubber hose 62 to receive water from the water source. The water source is input through the right-angle tube 61. The other end of the right-angle tube 61 is equipped with a delivery pump 6 via screws. The right-angle tube 61 can receive the water source delivered by the delivery pump 6. The suction end of the delivery pump 6 is equipped with a bend pipe via screws. The delivery pump 6 can extract water source through the bend pipe. The other end of the bend pipe is equipped with a water extraction pipe 91 via screws. The bend pipe can extract water source through the water extraction pipe 91. A hollow water tank 9 is fixedly connected to the periphery of the water extraction pipe 91. The water extraction pipe 91 can extract water source inside the hollow water tank 9. The lower end of the hollow water tank 9 is installed on the hollow base shell 2 via screws for easy installation and removal. The upper end of the hollow water tank 9 is threadedly connected to a tank cover 92. When the tank cover 92 is opened, water source can be added to the hollow water tank 9.

[0028] Working principle: When walking on land, the first electric telescopic cylinder 12 is activated through the control panel 7, the universal wheel 1 is unfolded and rotated, and the equipment is pushed to the edge of the paddy field. After entering the paddy field, the universal wheel is retracted to the storage tank 28, the air pump 22 is activated, the inflatable airbag 24 pushes the cross smooth sleeve 21 to extend, and the device is switched to the gliding mode. Personnel push the equipment to move in the paddy field.

[0029] Upon reaching the measurement point, the lifting and measuring mechanism is activated via the control panel 7. The lead screw motor 51 drives the lead screw slider 52 and the infrared sensing measuring mechanism to descend. The movable sensing sleeve 41 first contacts the surface of the mud layer and positions itself according to the surface height. The positioning shaft 43 continues to descend, and the pressure sensor 421 of the contact sensing component contacts the bottom of the mud layer. When the pressure reaches 5N, a signal is sent to the control panel 7, and the lead screw motor 51 stops. The infrared sensor 4 measures the distance to the movable sensing sleeve 41. The control panel 7 automatically calculates and displays the mud layer thickness. At the same time, the temperature and humidity sensor 45 and the pH sensor 46 detect soil parameters and display them synchronously on the control panel 7.

[0030] After the measurement is completed, the spray rinsing mechanism is started. The delivery pump 6 draws water from the hollow water tank 9 and forms water mist through the rubber hose 62 and the hollow spray hood 3's perforated panel 31 to clean the dirt on components such as the positioning shaft 43 and pressure sensor 421. After cleaning, the control panel 7 automatically stores the measurement data. Personnel then push the equipment to the next measurement point and repeat the above process.

[0031] The wiring diagrams of the first electric telescopic cylinder 12, air pump 22, lead screw motor 51, delivery pump 6, infrared sensor 4, pressure sensor 421, temperature and humidity sensor 45, pH sensor 46, and control panel 7 in this invention are common knowledge in the field, and their working principles are known technologies. The corresponding models can be selected according to actual usage requirements, so the control method and wiring layout will not be explained in detail.
