Technical Field
[0001] This utility model relates to the field of grain processing technology, specifically to a grain drying and detection device for grain processing. Background Technology
[0002] Food crops are a general term for cereal crops, tuber crops, and legume crops. For example, when processing corn kernels, it is necessary to test the dryness of the corn kernels.
[0003] When using traditional testing devices, staff move the device to the location where corn kernels are stored, insert the probe into the corn pile to analyze its moisture content, and then compare the results to determine the dryness of the corn kernels.
[0004] However, because the probe on the device is relatively long, it is easy for the long probe to collide with external objects during transport, especially the detection end of the probe. Once subjected to external impact, the internal sensor components may be displaced or malfunction, directly affecting the subsequent detection accuracy, thus making it inconvenient to carry the detection device. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a grain drying detection device for grain processing. It solves the problem that the overall length of the probe on the device is relatively long, which makes it easy for the long probe to collide with external objects during transport. Once subjected to external impact, the internal sensor elements may be displaced or malfunction, making it inconvenient to carry the detection device.

[0011] Beneficial effects
[0012] This utility model provides a grain drying detection device for grain processing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Because the probe on the device is relatively long, it is easy for the long probe to collide with external objects during transport. Once subjected to external impact, the internal sensor components may shift or malfunction, making it inconvenient to carry the detection device.
[0021] In view of this, the present invention provides a grain drying detection device for grain processing. By cooperating with hollow column, upright rod, screw, threaded hole, limiting block and limiting groove, the overall length of the probe is reduced. This solves the problem that the overall length of the probe on the device is relatively long, which makes it easy for the long probe to collide with external objects during the carrying process. Once subjected to external impact, the internal sensor elements may be displaced or malfunction, making it inconvenient to carry the detection device.
[0022] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.
[0023] Example 1, by Figure 1-4It is understood that the grain drying and detection device for grain processing in this case includes a shell 1, a cover plate 2 fixedly connected to the front of the shell 1, a handle 3 fixedly connected to the bottom of the shell 1, a moisture sensor 18 provided on the top of the shell 1, and a telescopic structure provided on the top of the shell 1; the telescopic structure includes a hollow column 11, a vertical rod 12, a screw 13, a threaded hole 14, a limiting block 15, and a limiting groove 16; the hollow column 11 is fixedly connected to the top of the shell 1, the vertical rod 12 is sleeved on the inner wall of the hollow column 11, the top of the vertical rod 12 is fixedly connected to the bottom of the moisture sensor 18, the inner wall of the vertical rod 12 has a threaded hole 14, the surface of the hollow column 11 is threadedly connected to the screw 13, the outer wall of the screw 13 is threadedly connected to the inner wall of the threaded hole 14, the bottom of the vertical rod 12 is fixedly connected to the limiting block 15, the inner wall of the hollow column 11 has a limiting groove 16, and the outer wall of the limiting block 15 is slidably engaged with the inner wall of the limiting groove 16;
[0024] In the specific implementation process, it is worth noting that the outer wall of the handle 3 is covered with an anti-slip rubber sleeve, and the surface has an arc-shaped groove to fit the palm, so that there is no fatigue when holding it for a long time. The hollow column 11, the upright rod 12 and the moisture sensor 18 form the probe. The moisture sensor 18 is a Decagon5TM model. The moisture sensor 18 can be connected to the upright rod 12 by bolts. The outer shell 1 and the cover plate 2 can be connected by bolts. A rubber gasket is set between the two to improve the sealing between them. The rubber gasket can be made of silicone rubber. By turning the bolts, the operator can replace the moisture sensor 18 or disassemble the cover plate 2 to repair or replace the components inside the outer shell 1.
[0025] When the detection device is in operation, the operator first moves the entire device to the location of the corn pile. Then, the operator rotates the screws 13 on both sides, causing the screws 13 to rotate within the hollow column 11 and move out of the threaded hole 14. After this, the operator moves the upright rod 12, which moves within the hollow column 11 and drives the limiting block 15 to move. The limiting block 15, located in the limiting groove 16, limits the movement of the upright rod 12, thereby moving the moisture sensor 18 and removing the upright rod 12. Finally, the operator rotates the screws 13 again, rotating them back into the upright rod. The pole 12 is fixed in the threaded hole 14 at the bottom of the pole 12. After that, the worker holds the handle 3 and moves the handle 3, thereby moving the outer shell 1. The outer shell 1 moves the moisture sensor 18 and inserts the moisture sensor 18 into the corn pile to start analyzing the moisture of the corn and thus detect the dryness. After the test is completed, the worker takes the moisture sensor 18 out of the corn pile and repeats the above steps to move the pole 12 back into the hollow column 11. The screw 13 is rotated into the threaded hole 14 above the pole 12 to reduce the overall length of the probe.
[0026] Furthermore, a sealing ring 17 is fixedly connected to the upper part of the inner wall of the hollow column 11, and the inner wall of the sealing ring 17 is attached to the outer wall of the upright 12.
[0027] In the specific implementation process, it is worth noting that the sealing ring 17 is made of fluororubber. The sealing ring 17 can prevent grain dust from entering the interior of the hollow column 11, avoid dust accumulation affecting the sliding of the upright 12, and increase the sealing between the hollow column 11 and the upright 12.
[0028] Furthermore, the inner wall of the outer casing 1 is respectively fixed with a signal acquisition module 4, a power supply module 5, a signal analysis and processing module 6, and an input / output module 7, and the front of the cover plate 2 is respectively fixed with a control button 8 and an LED display module 9.
[0029] In the specific implementation process, it is worth noting that the power supply module 5 provides power to the entire detection device, the signal acquisition module 4 is an STM32L051C8T6, the power supply module 5 is a TP4056+XL6009 combination module, the signal analysis and processing module 6 is an STM32F407VET6, the input / output module 7 is a PCF8574TI / O expansion module, the LED display module 9 is an MC-7825G, the signal output terminal of the moisture sensor 18 is connected to the PA0ADC input pin of the signal acquisition module 4 to realize the acquisition of moisture analog signals, the signal acquisition module 4 establishes serial communication with the USART3RX / TX pin of the signal analysis and processing module through the TX / RX pin of USART2 to transmit the acquired data, the signal analysis and processing module connects to the SPI interface of the LED display module 9 through the SCLK / MOSI pin of SPI1 to complete the detection data display drive, at the same time, its I2C1 SDA / SCL pin is connected to the 2C interface of the input / output module 7, and the input pin of the input / output module 7 is connected to the control button 8 for command input;
[0030] After the signal acquisition module 4 is initialized, it monitors the 0-3.3V analog signal output by the moisture sensor 18 in real time. The built-in 12-bit ADC quantizes the signal at a sampling rate of 384kHz, converting the physical quantity of moisture into a digital signal. Subsequently, the signal acquisition module 4 continuously sends the digital signal to the USART3 interface of the signal analysis and processing module 6 via the USART2 interface according to a preset communication protocol (e.g., baud rate 9600bps), completing the transmission of raw data. Upon receiving the data, the signal analysis and processing module 6 activates its built-in moisture-temperature compensation algorithm, combining the ambient temperature parameters (acquired by the auxiliary temperature sensor) to correct the raw data, eliminating errors caused by temperature fluctuations (e.g., accuracy correction within the 0℃-50℃ range). The processed moisture value (accuracy ±0.8%) is sent to the LED display module 9 via the SPI1 interface, driving it to display in real time in digital form. On the other hand, it is compared with the moisture threshold preset by the control button 8 (instruction transmitted through the input / output module 7). If the threshold is exceeded, an alarm signal is triggered. The input / output module 7 maintains communication with the signal analysis and processing module 6 through the I2C interface. Throughout the operation, all modules maintain consistent signal reference levels through a unified ground circuit design. The LED display module 9 displays the current moisture value, threshold, and equipment status in real time. The control button 8 serves as the core of human-machine interaction, allowing staff to intervene at any time to adjust the detection parameters, ensuring efficient and accurate operation of the device in grain drying detection scenarios.
[0031] Furthermore, a charging port 10 is fixedly connected to the side wall of the outer casing 1;
[0032] In the specific implementation process, it is worth noting that the recommended model for charging port 10 is a Micro-USB female connector (such as the BM10B-7.2-2P model). This model has a small interface size, supports 5V / 2A fast charging, and has a reverse insertion protection design, making it suitable for portable devices. The connection method between charging port 10 and power module 5 is as follows: the VCC pin of charging port 10 is directly connected to the Vin input terminal of the TP4056 charging management module in the power module, and the GND pin shares the same ground with the GND pin of TP4056. At the same time, the ID pin of charging port 10 is left floating. In this way, when an external charger is plugged into charging port 10, electrical energy can be used to charge the lithium battery through the TP4056 module, realizing efficient connection between the power module and external power supply. When the power module 5 is out of power, the staff can charge the power module 5 through charging port 10.
[0033] Example 2, by Figure 1-4It can be seen that the front of the cover plate 2 is provided with an anti-accidental collision structure; the anti-accidental collision structure includes a cover body 19, a connecting ear 20, a horizontal block 21 and a stud 22; the cover body 19 is hinged to the lower front of the cover plate 2, the side wall of the cover body 19 is fixedly connected with the connecting ear 20, the front of the cover plate 2 is fixedly connected with the horizontal block 21 near the connecting ear 20, and the inner wall of the horizontal block 21 and the inner wall of the connecting ear 20 are respectively threaded with studs 22;
[0034] In the specific implementation process, it is worth noting that the cover 19 is made of transparent PC material (2mm thick). When the detection device is working, the operator first rotates the knob on the top of the stud 22, thereby rotating the stud 22 out of the connecting ear 20 and fixing the cover 19. The cover 19 is then opened to expose the control button 8. The operator starts the entire device through the control button 8. After completion, the operator rotates the cover 19 back to the initial position and rotates the stud 22 back into the connecting ear 20 to fix the cover 19. When the device is working, the cover 19 covers the control button 8 to prevent the operator from accidentally touching the control button 8. When the device is finished working, the above steps are repeated. The operator closes the entire device through the control button 8, thus achieving the function of covering the control button 8 during the operation of the detection device.
[0035] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
