Abstract
Description
Technical Field

[0002] The detection and monitoring of temperature and humidity during the storage of finished grains are important measures to ensure the quality and safety of grains. The storage temperature of finished grains should be maintained within an appropriate range to prevent the occurrence of mildew, pests, and other quality problems. Generally, it is more appropriate to control the temperature of grain storage below 20 degrees Celsius.
[0003] Activities of mildew or fungi, occurrence of pests, uneven ventilation, irrigation, etc. can all cause local temperature rise or abnormality inside the finished grain stack. There may be tiny humid areas inside the stack, providing conditions for the growth of mildew or fungi; these microorganisms can reproduce in the grains, generate heat, and cause local temperature rise. The stored finished grains may be invaded by pests, the activities of insects will generate heat, and they may gather inside the stack, resulting in local temperature rise. Poor ventilation systems or uneven ventilation may cause different temperatures in different areas of the stack, and some areas may not receive sufficient ventilation, leading to local temperature rise. Waterlogging caused by rain leakage at some positions in the granary may lead to local humidity and heat generation, thus affecting the quality of grains.

[0039] Figures 1-9 As shown, it is a preferred embodiment of the intelligent finished grain tray capable of measuring the temperature inside the loaded grain pile. The intelligent finished grain tray capable of measuring the temperature inside the loaded grain pile includes several groups of laser distance measuring mechanisms, a temperature measuring cable 13, a tray base 4, and a control unit.
[0040] Combined with Figures 1-3As shown, each set of the laser distance measuring mechanism includes a laser distance measuring rod 1, a stop rod 3, a connecting rod 6, a servo 8 and a motor 7.
[0041] The tray base 4 is provided with a plurality of hollow channels 5. The connecting rod is arranged in the hollow channel 5. One end of the connecting rod is connected to the laser distance measuring rod 1, and the other end is connected to the stop rod 3. The laser distance measuring rod 1 and the stop rod 3 are correspondingly arranged on both sides of the tray base 4. The servo 8 is connected to the connecting rod 6 and is used to drive the connecting rod 6 to rotate, so as to drive the laser distance measuring rod 1 and the stop rod 3 to swing laterally synchronously, and scan the side wall of the finished grain pile in a linear scanning manner. A plurality of laser distance measuring modules 11 are longitudinally arranged on the laser distance measuring rod 1. The laser distance measuring module 11 is used to measure the depth information of the gap between the finished grain bags and transmit it to the control unit. The stop rod 3 is used to cooperate with the laser distance measuring rod 1 to limit the detection range of the laser distance measuring rod 1.
[0042] Preferably, the laser distance measuring rod 1 and the stop rod 3 have the same size specifications, and the laser distance measuring rod 1 and the stop rod 3 always remain parallel and are driven by the same servo 8. The synchronous rotation of the laser distance measuring rod 1 and the stop rod 3 is controlled by the drive of the servo 8, so that the distance information collected by the laser distance measuring module 11 can be kept within the depth range of the grain pile, ensuring that the laser distance measuring module 11 does not collect a distance exceeding the width of the grain pile.
[0043] The middle part of the laser distance measuring rod 1 is hollow and is provided with a moving channel for the temperature measuring cable 13. A channel communicating with the inside of the laser distance measuring rod 1 is arranged inside the connecting rod. The motor 7 is used to drive the temperature measuring cable 13 to move along the channels inside the connecting rod and the laser distance measuring rod 1.
[0044] In an embodiment of the present invention, there are two sets of laser distance measuring mechanisms, and the working space is separated. The two laser distance measuring rods 1 can increase the scanning area when working and find a more suitable grain pile gap. The number of laser distance measuring mechanisms can be adjusted according to the size of the tray.
[0045] Further, the distance measuring rod group is divided into two parts, namely a distance measuring module rod and a stop rod. The distance measuring module rod and the stop rod realize synchronous parallel rotation through two rotating shafts connected to the same servo. After receiving the temperature measuring instruction, the two groups of distance measuring rod groups respectively drive the servo to scan the length of the grain pile gap within their jurisdiction once, and then the deepest gap between the grain bags can be sensed from the side.
[0046] The control unit is respectively connected to the laser ranging module 11, the steering gear 8, the motor 7, and the temperature measuring cable 13. After the control unit receives the depth information detected by the laser ranging rod 1 and determines the deepest gap between the finished grain bags and its position information, it controls the steering gear 8 to return the laser ranging rod 1 and the blocking rod 3 to the position of the deepest gap between the finished grain bags, controls the laser ranging module 11 corresponding to the position of the deepest gap between the finished grain bags to be turned off, controls the motor 7 to drive the temperature measuring cable 13 to pass through the laser ranging module 11 corresponding to the position of the deepest gap between the finished grain bags and extend into the deepest gap between the finished grain bags to sense the temperature inside the grain pile here and transmit the temperature data to the control unit.
[0047] The grain tray adopted in the present invention can monitor the temperature inside the grain pile it bears. After detecting the depth information of the gap between the finished grain bags through the laser ranging rod 1 and determining the deepest gap between the finished grain bags and its position information, it drives the temperature measuring cable 13 to pass through the laser ranging module 11 corresponding to the position of the deepest gap between the finished grain bags and extend into the deepest gap between the finished grain bags to sense the temperature inside the grain pile here and transmit the temperature data to the control unit, which can provide more accurate and detailed temperature parameters of each grain pile in the granary for the granary management personnel, can manage the granary more effectively, and achieve the purpose of saving grain and reducing losses during the warehousing stage.
[0048] Combined Figures 4-8 As shown, according to this embodiment, preferably, a plurality of guiding mechanisms are further provided along the longitudinal direction of the laser ranging rod 1; one guiding mechanism is matched with one laser ranging module 11; each guiding mechanism includes a guiding channel 12, a gear 14, and a driving motor; the guiding channel 12 is installed on the through hole of the laser ranging rod 1, and the guiding channel 12 is a hollow structure including a bent section 9 and a straight rod section 10; the upper surface of the guiding channel 12 is provided with a tooth-shaped structure; the driving motor and the gear 14 are installed on the laser ranging rod 1, the gear 14 meshes with the tooth-shaped structure, the driving motor is connected to the gear 14, and the driving motor drives the gear 14 to rotate, thereby driving the guiding channel 12 to stretch from one side of the laser ranging rod 1 to the other side; the temperature measuring cable 13 moves along the connecting rod 6 and the channel inside the laser ranging rod 1, enters through the bent section 9, passes through the straight rod section 10 and then penetrates out, and extends into the gap between the grain bags; the driving motor is connected to the control unit.
[0049] In an embodiment of the present invention, a guiding channel 12 is provided 2 cm above each laser ranging module 11. The driving motor drives the gear 14 to enable the guiding channel 12 to extend into the gap of the grain pile and serve as a constraint channel for guiding the temperature measuring cable 13. The width of the internal channel of the guiding channel 12 is slightly larger than the diameter of the temperature measuring cable 13, which can ensure the smooth sliding of the temperature measuring cable 13.
[0050] The multiple guiding mechanisms of the laser distance measuring rod 1 of the present invention facilitate the smooth arrival of the temperature measuring cable 13 at the deepest gap position between the finished grain bags.
[0051] In an embodiment of the present invention, each of the guiding mechanisms includes two gears 14; the gears 14 are respectively arranged on both sides of the laser distance measuring rod 1, and are both engaged with the toothed structure. The gears 14 are respectively connected to the driving motors and are driven by the driving motors to control the forward and backward movement of the guiding channel 12. The two gears 14 control the forward and backward movement of the guiding channel 12 more conveniently and quickly.
[0052] According to this embodiment, preferably, it further includes several elevation rods 2; the elevation rods 2 are arranged on the tray base 4.
[0053] In an embodiment of the present invention, the number of the elevation rods 2 is four, and the four elevation rods 2 are respectively vertically arranged at the four corners of the tray base 4. The height of the elevation rods 2 is the same as that of the laser distance measuring rod 1. The elevation rods 2 can help the granary management personnel control the height of the grain pile, so that the height of the grain pile matches the height of the laser distance measuring rod 1, which is more conducive to measuring the temperature of the grain pile. The part of the grain pile exceeding the recommended height cannot sense its temperature, and there is a risk of the grain pile tilting and collapsing. The elevation rods 2 keep the grain at a convenient height for measurement and also keep the grain pile in a more reasonable center of gravity so that the grain pile is not prone to tilting and collapsing. And compared with the traditional grain tray, the grain tray designed by the present invention can more effectively reduce the probability of the grain pile tilting and collapsing.
[0054] According to this embodiment, preferably, the control unit is a single-chip microcomputer.
[0055] Combined Figure 9 As shown, a measuring method for an intelligent finished grain tray capable of measuring the temperature inside the carried grain pile includes the following steps:
[0056] The control unit controls the steering gear 8 to drive the connecting rod 6 to rotate, thereby driving the laser distance measuring rod 1 and the blocking rod 3 to swing horizontally synchronously, and scanning the side wall of the finished grain pile in a linear scanning manner. The laser distance measuring module 11 measures the depth information of the gap between the finished grain bags and transmits it to the control unit;
[0057] After the control unit receives the depth information detected by the laser distance measuring rod 1 and determines the deepest gap between the finished grain bags and its position information, it controls the steering gear 8 to return the laser distance measuring rod 1 and the blocking rod 3 to the position of the deepest gap between the finished grain bags, and controls the laser distance measuring module 11 corresponding to this deepest gap between the finished grain bags to close. It controls the motor 7 to drive the temperature measuring cable 13 to pass through the laser distance measuring module 11 corresponding to this deepest gap between the finished grain bags and extend into this deepest gap between the finished grain bags to sense the temperature inside the grain pile here and transmit the temperature data to the control unit.
[0058] According to this embodiment, preferably, it further includes a guiding step:
[0059] The control unit controls the laser ranging module 11 corresponding to the position of the deepest gap between the finished grain bags to be turned off, and controls the drive motor of the guiding mechanism matched with the laser ranging module 11 to drive the gear 14 to rotate, thereby driving the guiding channel 12 to extend from one side of the laser ranging rod 1 to the other side;
[0060] The control unit controls the motor 7 to drive the temperature measuring cable 13 to move along the channels inside the connecting rod 6 and the laser ranging rod 1, enter from the bending section 9, pass through the straight rod section 10 and then pass out, and extend into the deepest gap between the finished grain bags.
[0061] The usage process of the present invention:
[0062] When the finished grain is put into the warehouse, the staff compares with the elevation rod 2 to stack the grain, stacks the grain on the tray base 4 and completes the discharge of the grain pile in the whole granary through the machine. After the stacking work is completed, the administrator can issue a temperature measurement instruction as needed. After receiving the temperature measurement instruction, the control unit controls the steering gear 8 to rotate, and at the same time turns on all the laser ranging modules 11. The laser ranging rod 1 can sense the depth of all the gaps between the grain bags when sweeping across the side of the finished grain pile driven by the steering gear 8, and saves the gap between the grain bags at each position in the database. After completing a round of scanning, the position of the deepest gap between the grain bags in the middle of the grain pile can be obtained. Control the steering gear 8 to make the laser ranging rod 1 rotate to the position of the deepest gap, and control the temperature measuring cable 13 in the laser ranging rod 1 to extend through the motor; control the drive motor of the guiding mechanism matched with the laser ranging module 11 to drive the gear 14 to rotate, thereby driving the guiding channel 12 to extend from one side of the laser ranging rod 1 to the other side; the control unit controls the motor 7 to drive the temperature measuring cable 13 to move along the channels inside the connecting rod 6 and the laser ranging rod 1, enter from the bending section 9, pass through the straight rod section 10 and then pass out, and extend into the deepest gap between the finished grain bags to sense the temperature inside the grain pile at this place and transmit the temperature data to the control unit. The control unit is connected to the granary control system and transmits the temperature information to the control system.
[0063] The present invention scans the side wall of the grain pile through the laser ranging mechanism to obtain the position of the deepest gap between the grain bags. The laser ranging rod 1 returns to this position again and controls the movement of the corresponding guiding channel 12 at this position so that the temperature cable 13 can extend into the grain pile gap along the guiding channel 12, sense the temperature inside the grain pile and transmit it back to the control system terminal, so that the management personnel can obtain the accurate temperature inside the grain pile.
