Description

Technical Field

[0001] This invention relates to the field of moisture measuring instruments, specifically a moisture measuring instrument for cotton testing. Background Technology

[0002] Cotton typically contains moisture, and the moisture content directly affects its quality and weight. During cotton transportation, it's usually necessary to test the moisture content to determine the amount of cotton being transported. Current methods for cotton moisture detection typically use resistance methods, which utilize the different resistance values ​​between two electrodes for cotton with varying moisture content. By analyzing the relationship between voltage, humidity, and resistance, the moisture content of the cotton can be determined.

[0003] Cotton testing typically involves extracting cotton samples and then testing them using a fixed-cavity moisture analyzer, or directly using electrode pins inserted into bagged cotton to detect moisture content based on the resistance of the pins. While fixed-cavity moisture analyzers offer high accuracy, they require cotton sampling, which is often limited to the surface of the conveying cotton, making the process complex. While electrode pin testing allows for deeper sampling of the conveying cotton and is simpler, it is often limited to bagged cotton and has lower accuracy. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a moisture meter for cotton testing, which has the advantages of simple operation, convenient for deep cotton testing, good testing effect, and high testing accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a moisture meter for cotton detection, comprising a detection block, a conical head fixedly connected to the bottom of the detection block, a control lever fixedly connected to the top of the detection block, a cotton-feathering nail fixedly connected to the top of the detection block, the detection block including an outer cavity wall, an outer blocking ring movably connected inside the detection block, a first telescopic rod disposed between the outer blocking ring and the detection block, a second telescopic rod fixedly connected inside the detection block, a push plate fixedly connected to the top of the second telescopic rod, a top driving block fixedly connected to the outside of the control lever, a top pressure rod rotatably connected to the outside of the top driving block, a buffer protrusion fixedly connected to the top of the top driving block, and a moisture detection mechanism disposed between the detection block and the top pressure rod.

[0006] Preferably, the control lever and the detection block are coaxial, the first telescopic rod is used to drive the outer blocking ring to slide up and down inside the outer cavity wall of the detection block, and five loop pins are provided, which are centrally symmetrically arranged around the inside of the outer blocking ring.

[0007] Preferably, at least six sets of the first telescopic rods are provided, and the first telescopic rods are symmetrically distributed inside the detection block. Three sets of the second telescopic rods are provided. The second telescopic rods are used to drive the push plate to move on the top of the detection block. The control lever and the felting nail penetrate the push plate. The felting nail extends from the inside of the detection block to the top of the detection block. The outer diameter of the push plate and the inner diameter of the outer barrier ring are adapted to each other.

[0008] Preferably, the moisture detection mechanism includes a lower electrode plate and an upper electrode plate. The lower electrode plate is fixedly connected to the top of the push plate, and the upper electrode plate is fixedly connected to the bottom of the top pressure rod. A pressure sensor and a temperature sensor are provided on the top of the lower electrode plate. The pressure sensor, temperature sensor, lower electrode plate, and upper electrode plate are electrically connected to a power control board. A support block is provided between the power control board and the detection block.

[0009] Preferably, a flexible power cable is provided between the pressure sensor, temperature sensor, lower electrode plate, and power control board.

[0010] Preferably, six top pressure rods are provided, symmetrically distributed on the outside of the top drive block. A hydraulic drive rod is provided between the top drive block and the top pressure rods, which is used to control the top pressure rods to flip outward and cover the top of the outer barrier ring or to control the top pressure rods to retract inside the top drive block.

[0011] Preferably, the longitudinal cross-section of the top drive block and the buffer bump is prismatic.

[0012] Preferably, the control lever is used to connect to an external hydraulic drive cylinder, which controls the up-and-down movement of the detection block via the control lever. The detection block is located at the top of the cotton conveyor belt.

[0013] Beneficial effects:

[0014] 1. This moisture meter for cotton testing uses a top-mounted pin on the detection block that inserts into the cotton. The pin rotates the cotton inside, separating it from the outer cotton. An outer barrier ring isolates the separated cotton by the pin's rotation. Simultaneously, the top drive block controls a pressure rod to flip downwards. The pressure rod, in conjunction with the outer barrier ring, creates a testing space containing the sampled cotton separated by the pin. This completes the sampling and separation of the cotton to be tested. The entire device facilitates deep sampling and separation of cotton, enabling deep cotton testing. Furthermore, the operation is simple, with low requirements on the overall external condition of the cotton. Therefore, it is convenient for testing cotton under different conveying conditions, thus facilitating moisture detection and effectively improving the device's performance.

[0015] 2. This moisture meter for cotton detection uses a second telescopic rod to push a pressure plate up and down inside the outer barrier ring. This causes the lower and upper electrode plates to work together to compress the cotton, facilitating moisture detection. Pressure and temperature sensors simultaneously detect the cotton's pressure and temperature. Voltage is applied between the lower and upper electrode plates, and the resistance between them is measured. The moisture content of the cotton is determined by the relationship between voltage, humidity, temperature, and resistance. This allows for direct moisture detection inside the cotton. Compared to existing pin-type moisture detectors, this instrument provides an independent detection space, effectively controlling or detecting various parameters, thus ensuring higher detection accuracy, improving detection results, avoiding the hassle of sampling, and increasing detection efficiency.

[0016] 3. The moisture meter for cotton detection, by setting a conical head and a buffer protrusion, facilitates the downward pushing of the detection block. At the same time, the top pressure rod is retracted inside the top drive block, and the second telescopic rod pushes the push plate outward outside the tufting nail, so that the cotton wrapped around the tufting nail is pushed out. Then, when the control rod moves outward, the buffer protrusion detects the damping of the outward movement, and the push plate prevents the tufting nail from continuing to wrap the cotton, which facilitates the removal of the detection block and effectively ensures the use effect of the device.

[0023] 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.

[0024] Example 1

[0025] Please see Figure 1-5 A moisture meter for cotton detection includes a detection block 1, a conical head 2 fixedly connected to the bottom of the detection block 1, a control lever 3 fixedly connected to the top of the detection block 1, a tufting nail 4 fixedly connected to the top of the detection block 1, the detection block 1 including an outer cavity wall, an outer blocking ring 5 movably connected inside the detection block 1, a first telescopic rod 6 disposed between the outer blocking ring 5 and the detection block 1, a second telescopic rod 7 fixedly connected inside the detection block 1, a push plate 8 fixedly connected to the top of the second telescopic rod 7, a top drive block 14 fixedly connected to the outside of the control lever 3, a top pressure rod 15 rotatably connected to the outside of the top drive block 14, a buffer protrusion 17 fixedly connected to the top of the top drive block 14, and a moisture detection mechanism disposed between the detection block 1 and the top pressure rod 15.

[0026] refer to Figure 5 The control lever 3 and the detection block 1 are coaxial. The first telescopic rod 6 is used to drive the outer barrier ring 5 to slide up and down inside the outer cavity wall of the detection block 1. Five loop pins 4 are provided, which are centrally symmetrically arranged around the inside of the outer barrier ring 5. The outer barrier ring 5 extends and moves to the outside of the detection block 1 to form a moisture detection space.

[0027] At least six sets of first telescopic rods 6 are provided, and the first telescopic rods 6 are symmetrically distributed inside the detection block 1. Three sets of second telescopic rods 7 are provided. The second telescopic rods 7 are used to drive the push plate 8 to move on the top of the detection block 1. The control rod 3 and the felting nail 4 pass through the push plate 8. The felting nail 4 extends from the inside of the detection block 1 to the top of the detection block 1. The outer diameter of the push plate 8 and the inner diameter of the outer barrier ring 5 are matched.

[0028] The overall longitudinal cross-section of the top drive block 14 and the buffer protrusion 17 is prismatic, making both the insertion end and the extraction end of the device conical, which facilitates the insertion or removal of the detection block 1.

[0029] The control lever 3 is used to connect to an external hydraulic drive cylinder. The hydraulic drive cylinder controls the up and down movement of the detection block 1 through the control lever 3. The detection block 1 is located at the top of the cotton conveyor belt.

[0030] The testing process includes a hydraulically driven cylinder controlling the insertion of the testing block 1 into the cotton conveying system via a control lever 3, and a conical head 2 reducing the resistance of the testing block 1 into the cotton, facilitating the detection of the cotton's depth.

[0031] When the detection block 1 is deeply inserted into the cotton, the cotton at the rear of the detection block 1 presses against the vicinity of the control lever 3 under mutual pressure, and then the detection block 1 is pulled backward. The top of the detection block 1, the tufted nail 4, penetrates into the cotton. Then the detection block 1 is rotated, and the tufted nail 4 drives the cotton inside to rotate, separating it from the outer cotton. Then the first telescopic rod 6 controls the outer blocking ring 5 to push towards the top of the detection block 1. The outer blocking ring 5 isolates the cotton separated by the rotating tufted nail 4. At the same time, the top drive block 14 controls the top pressure rod 15 to flip downward. The top pressure rod 15, together with the outer blocking ring 5, constructs the space to be tested. The space to be tested contains the sampled cotton separated by the tufted nail 4, thus completing the sampling and separation of the cotton to be tested.

[0032] The overall device facilitates deep sampling and separation of cotton, and makes it easy to test deep cotton. At the same time, the overall operation is simple and has low requirements for the overall external condition of the cotton. Therefore, it is convenient to test cotton in different conveying states, and thus facilitates the detection of cotton moisture, effectively improving the use effect of the device.

[0033] Example 2

[0034] Please see Figure 1-5 A moisture meter for cotton detection includes a detection block 1, a conical head 2 fixedly connected to the bottom of the detection block 1, a control lever 3 fixedly connected to the top of the detection block 1, a tufting nail 4 fixedly connected to the top of the detection block 1, the detection block 1 including an outer cavity wall, an outer blocking ring 5 movably connected inside the detection block 1, a first telescopic rod 6 disposed between the outer blocking ring 5 and the detection block 1, a second telescopic rod 7 fixedly connected inside the detection block 1, a push plate 8 fixedly connected to the top of the second telescopic rod 7, a top drive block 14 fixedly connected to the outside of the control lever 3, a top pressure rod 15 rotatably connected to the outside of the top drive block 14, a buffer protrusion 17 fixedly connected to the top of the top drive block 14, and a moisture detection mechanism disposed between the detection block 1 and the top pressure rod 15.

[0035] The moisture detection mechanism includes a lower electrode plate 9 and an upper electrode plate 16. The lower electrode plate 9 is fixedly connected to the top of the push plate 8, and the upper electrode plate 16 is fixedly connected to the bottom of the top pressure rod 15. A pressure sensor 10 and a temperature sensor 11 are provided on the top of the lower electrode plate 9. The pressure sensor 10, the temperature sensor 11, the lower electrode plate 9 and the upper electrode plate 16 are electrically connected to a power control board 12. A support block 13 is provided between the power control board 12 and the detection block 1.

[0036] A flexible power cable is provided between the pressure sensor 10, the temperature sensor 11, the lower electrode plate 9, and the power control board 12.

[0037] There are six top pressure rods 15, symmetrically distributed on the outside of the top drive block 14. A hydraulic drive rod is provided between the top drive block 14 and the top pressure rods 15, which is used to control the top pressure rods 15 to flip outward and press against the top of the outer barrier ring 5 or to control the top pressure rods 15 to retract inside the top drive block 14.

[0038] Based on Embodiment 1, the distinguishing feature lies in the detection process. During detection, the second telescopic rod 7 pushes the pressing plate 8 up and down inside the outer barrier ring 5, causing the lower electrode plate 9 and the upper electrode plate 16 to cooperate in squeezing the cotton, facilitating the detection of cotton moisture. The pressure sensor 10 and the temperature sensor 11 simultaneously detect the pressure and temperature of the cotton. The density of the cotton is determined by sensing the pressure of the cotton. A voltage is applied to the lower electrode plate 9 and the upper electrode plate 16, and the resistance between the lower electrode plate 9 and the upper electrode plate 16 is detected. The moisture content of the cotton is determined by the relationship between voltage, humidity, temperature, and resistance.

[0039] It facilitates direct moisture detection inside the cotton and, compared to existing pin-type moisture detectors, provides an independent detection space, enabling effective control or detection of various parameters, thereby ensuring higher detection accuracy, improving detection results, avoiding the hassle of sampling and detection, and increasing detection efficiency.

[0040] When the test is completed, continue to push the test block 1 downwards, while simultaneously retracting the top pressure rod 15 inside the top drive block 14. The second telescopic rod 7 pushes the push plate 8 outwards outside the loop pin 4, causing the cotton wrapped around the loop pin 4 to be pushed out. At the same time, the control lever 3 moves outwards, and the buffer protrusion 17 detects the damping of the outward movement. The push plate 8 prevents the loop pin 4 from continuing to wrap the cotton, making it easy to remove the test block 1 and effectively ensuring the performance of the device.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
