Description

Technical Field

[0001] The invention relates to the technical field of agricultural scientific research instruments, and in particular to an instrument for measuring the compactness of corn husks. Background Art

[0002] Corn husk, also known as corn husk, corn cob husk, corn skin, is the outer covering of the corn cob. From a botanical point of view, the corn cob is a modified side stem, and the husk is a modified leaf of corn.

[0003] The mechanized production of corn has become an inevitable trend. However, there are still many factors that restrict the mechanical harvesting of corn grains, such as harvesting machinery and variety suitability. The moisture content of corn grains at maturity is an important factor that determines the effect of mechanical harvesting of corn grains, and the characteristics of corn husks directly affect the dehydration of grains, the moisture content of grains, and the falling of grains during harvesting, which in turn affects the breakage of grains. Therefore, the characteristics of corn husks have always been an important part of studying the mechanical harvesting characteristics of corn.

[0004] Some studies have confirmed that increasing the number of corn husk layers or the dry weight of husks will affect the dehydration rate of kernels, while husks that are too thick, too long or too short are not conducive to the growth and development of the cob and harvesting. It can be seen that the number of corn husks and the degree of wrapping on the cob directly affect the moisture content of corn kernels and mechanical harvesting. Too many, too thick or too tight husks will affect the efficiency of manual or mechanical harvesting.

[0005] Corn husk compactness is an important observation object and is of great significance to agricultural production and scientific research. However, there is a lack of measurement equipment, which brings certain challenges to related research and practice. Summary of the invention

[0030] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Original Based on the embodiments of the present invention described, the present invention can be applied to some embodiments of the present invention, but not all embodiments. All other embodiments obtained by ordinary technicians in the field are within the scope of protection of the present invention.

[0031] In view of the defects and problems of the prior art, the present application provides a corn husk compactness measuring instrument, comprising: an instrument housing, a main circuit board, a retractable probe, a probe head, an input device and a display device;

[0032] The main circuit board is built into the instrument housing and controls the connection with the retractable probe so that the retractable probe can generate a retractable movement relative to the first surface of the instrument housing;

[0033] The probe is arranged at an end of the retractable probe away from the first surface, and is used to contact the corn husk, collect pressure signals, and transmit the pressure signals to the main circuit board, convert them into quantitative values ​​of the compactness of the corn husk, and display them on the display screen of the display device;

[0034] The display screen of the display device is arranged on the second surface of the instrument housing;

[0035] The input device is arranged on the third surface of the instrument housing, and is used to receive operations from a user (such as an agricultural producer or a scientific researcher) so that the main circuit board can generate control instructions for the retractable probe; or to receive recorded data input by the user so that the storage device on the main circuit board can record it.

[0036] Specifically, a controller is integrated on the main circuit board. The controller can be a control chip such as FPGA, CPLD, etc., which is used to control the entire function of the instrument, including signal input, acquisition, transmission, digital signal processing, screen display, etc.

[0037] The retractable probe is controlled by a transmission device such as a motor, and can move relative to the first surface after the main circuit board issues a control instruction for extension or retraction.

[0038] The probe can be selected from a variety of shapes, including cylindrical and conical. The radius of the cylindrical probe is adjustable.

[0039] In specific application scenarios, the conical probe is used when the top of the corn ear husk is tightly closed. The sharp top can be inserted between the husks to avoid damage to the husks caused by manual pulling, which affects the compactness measurement. The cylindrical probe can be used when the husks are loose. When the corn husks are loose and the opening is large, it can be replaced with a cylindrical probe with a larger radius to prevent the inability to measure due to the lack of pressure.

[0040] Optionally, the cylindrical probe can be designed as several probes with different radii. When the corn husk is loose and has a large opening, it can be replaced with a probe with a larger radius to prevent the failure to measure due to the lack of pressure. Alternatively, the cylindrical probe can be integrated with a metal sheet with an adjustable radius, so that the contact can be adjusted in real time according to the opening of the corn husk.

[0041] More specifically, the corn husk compactness measuring instrument converts physical pressure into electrical signals through a pressure sensor (sensing the pressure exerted when the probe contacts the corn husk). Husks with high compactness respond less to pressure, showing lower deformation or higher compressive strength, and the sensor will receive a stronger electrical signal; while husks with low compactness show larger deformation or lower compressive strength, and the electrical signal is weaker. The main circuit board amplifies, converts and processes these weak electrical signals, and finally converts the signals into data through an analog-to-digital converter to calculate the corn husk compactness. The calculation results will show The value is displayed on the instrument’s display screen for the user to read.

[0042] The input device may include: buttons and / or knobs and / or keyboards and / or touch screens. The user can control the retractable probe or input recorded data. The recorded data may be a combination of one or more data such as time, location, weather conditions (such as temperature and humidity), corn husk batch or serial number, etc. The input device is arranged on the third surface, preferably, the first surface faces the corn husk, and the third surface faces the user.

[0043] The display screen of the display device can display the quantitative value of the corn husk compactness, or display the recorded data input by the user in combination, and the display mode can be but not limited to text, numbers and charts. The second surface, preferably, also needs to face the user, and the second surface can be the same surface as the third surface.

[0044] The following is an explanation of two implementations of this instrument project in conjunction with the more detailed drawings of this application. The instruments in these two implementations are named Type I and Type II, respectively.

[0045] Figures 1 to 5 This is a related drawing of device type I.

[0046] This instrument is designed to be small and lightweight, and is designed to facilitate researchers to measure bract compactness anytime and anywhere. The instrument is small and can be easily put into a pocket for handheld operation. Its unique sensor design and adjustable top radius ensure that the radius of the sensor can be recorded while measuring bract compactness, thereby more accurately describing the bract condition.

[0047] In terms of the display system, the instrument can display basic information such as time, and can also record environmental information such as coordinates and save them together with the compactness data. In this way, users can not only obtain real-time bract compactness data during the measurement process, but also view historical measurement values ​​without exporting the data.

[0048] In addition, the instrument is waterproof and dustproof, suitable for outdoor use. Whether it is windy, rainy or dusty, it will not affect the normal operation of the instrument. In terms of data storage, the instrument is equipped with a memory card. Users can manually enter other information, such as plant number, temperature during measurement, etc., and save it together with the compactness data to facilitate subsequent data analysis and processing.

[0049] Figure 6 Device type II is illustrated.

[0050] Compared with the device type I, the corn husk compactness meter of device type II has been greatly improved in function and performance. In addition to all the functions of type I, type II also integrates GPS positioning function. Through the GPS module, the instrument can accurately record the measurement location and time, and display it in two marking modes: longitude and latitude and administrative division address. In this way, users can not only understand the distribution of husk compactness, but also associate geographical location information with it, further integrating the data.

[0051] At the same time, the Type II corn husk compactness meter also supports networking, and data can be easily exported to mobile phones. Users can view and manage measurement data simply through the mobile phone application, without complicated data cable connections or cumbersome data export steps. If conditions permit, in the case of a wireless network, the instrument also supports wireless transmission, which further simplifies the operation process and equipment structure.

[0052] In summary, the instrument of the present application has the advantages of small size, light weight, accurate measurement, convenient data recording and anti- waterproof The instrument is designed to be easy to hold and can be easily put into a pocket, suitable for use in the field. Real-time measurement greatly improves the convenience and efficiency of measurement. During the measurement process, the instrument automatically records the maximum value of husk pressure to ensure the accuracy of the results. At the same time, the equipped memory card allows the user to manually enter other relevant information, such as plant number and temperature during measurement, to facilitate subsequent data processing and analysis. The waterproof and dustproof design of the instrument enables it to work normally in various harsh outdoor conditions, enhancing durability and service life. This instrument can help measure the compactness of corn husks and provide support for related research on corn.
