Description

Technical Field

[0001] The invention relates to the field related to seedling raising experiments, and in particular to an ecological agricultural seedling raising experiment device and method based on physical ultrasonic detection. Background Art

[0002] Seedling cultivation means the cultivation of seedlings. Its original meaning refers to the cultivation of seedlings in a nursery, hotbed or greenhouse in preparation for transplanting into the land for planting. It can also refer to the stage when various organisms are artificially protected when they are small until they can survive independently.

[0003] In order to experiment with the optimal amount of nutrients required by seedlings during their growth, an agricultural seedling experimental device based on physical ultrasonic detection is disclosed, with announcement number: CN108592832B. The device can realize the addition of nutrient solution to the seedlings and can change the amount of nutrient solution added, but has the disadvantage that "each row of seedling trays corresponds to a nutrient solution supply tube, and each nutrient solution supply tube corresponds to an infusion pump, which can facilitate the comparative experiment of different nutrient solutions on seedling growth". The cost of this method is relatively high, and the test values ​​required in some large-scale cultivation are not accurate, so the number of tests required is relatively large. For example, if an infusion pump is set for each culture tray, the procurement cost and debugging cost are very high.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] For example, see Figures 1 to 14, an ecological agricultural seedling experimental device based on physical ultrasonic detection, comprising a machine base 1 and a No. 1 support plate 2 fixed on the machine base 1; a convex block 204 arranged on the No. 1 support plate 2 and formed integrally with it, a No. 2 support plate 4 is arranged on the convex block 204, a slider 401 is fixed on the No. 2 support plate 4, and the No. 2 support plate 4 slides with a slide rail 202 opened on the convex block 204 through the slider 401; two storage boxes 5 fixed on the top of the No. 2 support plate 4, and the tops of the two storage boxes 5 are fixed with No. 2 conveying pipes 502 connected thereto, and the No. 2 conveying pipes 502 are located on both sides of the No. 2 support plate 4, and the storage boxes 5 are connected to the pressure assembly on the No. 2 support plate 4 fixed on the machine base 1; an equidistant translation assembly installed on the No. 2 support plate 4, and the equidistant translation assembly is connected to the pressure assembly.

[0033] In the embodiment of the present invention, the rice seedlings are planted in the culture piece 3, and then the culture piece 3 is placed on the magnet 201 arranged on the No. 1 support plate 2. The iron sheet at the bottom of the culture piece 3 is adsorbed by the magnet 201 to achieve the positioning of the culture piece 3, so as to ensure that the culture piece 3 is in an equidistant state on the No. 1 support plate 2; when the equidistant translation component is working, it drives the No. 2 support plate 4 to move equidistantly and intermittently along the length direction of the slide rail 202, and at the same time drives the pressurizing component to work, and pressurizes the storage box 5 through the pressurizing component, and drives the liquid stored in the storage box 5 to flow into the culture piece 3 through the No. 2 delivery pipe 502 through the atmospheric pressure; so as to achieve that the No. 2 support plate 4 is between the two culture pieces 3 during the interval of translation. When the No. 2 support plate 4 is 4 is between the two culture pieces 3, liquid is added to the culture piece 3, the liquid is obtained by mixing nutrient solution and water, and its concentration is base 1: base 1; when the second support plate 4 is between the two culture pieces 3, the solenoid valve is driven to open by the ultrasonic transmitter 7, and the ultrasonic transmitter 7 can collect various data of the seedlings; the basic principle of ultrasonic technology is the premise for determining the moisture content of fruits and vegetables, the propagation speed of ultrasonic waves in different media is different, and water is one of the main components of most fruits and vegetables; it can be inferred that there is a certain relationship between the moisture content of fruits and vegetables and the propagation speed of ultrasonic waves in them, therefore, by measuring the propagation speed of ultrasonic waves in the sample, the moisture content of fruits and vegetables can be indirectly calculated.

[0034] Secondly, the application of ultrasonic technology in the determination of moisture content in fruits and vegetables is highly efficient. Traditional measurement methods usually require destructive treatment of fruit and vegetable samples, such as drying or grinding into powder, in order to determine the moisture content; these treatments are not only time-consuming, but also easily lead to loss of food quality; while ultrasonic technology can directly measure samples without any destructive treatment, greatly improving the efficiency of measurement.

[0035] At the same time, ultrasonic technology is also characterized by high precision and repeatability. Factors such as the short wavelength of ultrasonic waves, the choice of frequency, and the design of the probe will affect the measurement results. By rationally selecting the characteristics of ultrasonic waves and optimizing the measurement conditions, more accurate measurement results can be obtained. In addition, the repeatability of ultrasonic measurements is also very high, and the measurement results of the same sample have very small deviations in multiple measurements, providing reliable data support.

[0036] The equidistant translation assembly includes a No. 3 transmission rod 13 rotatably mounted on one side of the No. 2 support plate 4, and an incomplete gear 16 is coaxially fixed on the No. 3 transmission rod 13, and the incomplete gear 16 cooperates with the No. 1 rack plate 203 fixed on the protrusion 204; a motor 8 is also fixed to one side of the No. 2 support plate 4, and the output shaft of the motor 8 is connected to the No. 3 transmission rod 13 through a synchronous belt, and the No. 3 transmission rod 13 is connected to the pressurizing assembly.

[0037] In the embodiment of the present invention, when the motor 8 is working, its output shaft drives the third transmission rod 13 to rotate through the synchronous belt. When the third transmission rod 13 rotates, it drives the incomplete gear 16 coaxially fixed therewith to rotate. When the toothed part of the incomplete gear 16 rotates to mesh with the first rack plate 203, it continues to rotate to drive the incomplete gear 16 to translate, so as to drive the third transmission rod 13 and the second support plate 4 to move horizontally; when the toothed part of the incomplete gear 16 disengages from the first rack plate 203, the incomplete gear 16, the third transmission rod 13, and the second support plate 4 stop translating, and this period is the intermittent period.

[0038] Embodiment 2 is different from Embodiment 1 in that: the pressurizing assembly includes a No. 2 transmission rod 12 rotatably mounted on one side of the No. 2 support plate 4, the No. 2 transmission rod 12 is connected to the No. 3 transmission rod 13 via a No. 1 transmission chain 14, the No. 2 transmission rod 12 is sleeved with two stepping gears 17, the No. 2 transmission rod 12 is equidistantly fixed with transmission bars 1201 on the circumference, the transmission bars 1201 are slidably matched with the transmission grooves 1701 provided in the stepping gears 17, and the stepping gears 17 are ... sleeved with two stepping gears 17. The tooth length on 7 is set to increase in one direction, and the increase is at least three teeth at a time; an adjustment component is also installed on one side of the No. 2 support plate 4, and the adjustment component is connected to the stepping gear 17; receiving plates 15 are also fixed on both sides of the No. 2 support plate 4, and air cylinders 11 are fixed on the two receiving plates 15, and the air outlet end of the air cylinder 11 is connected to the storage box 5 through the No. 1 delivery pipe 501; wherein, the air cylinder movable rod 1103 of the air cylinder 11 cooperates with the stepping gear 17 through a transmission assembly.

[0039] The thickness of the first gear 1001 is the thickness of the 17 teeth of the stepping gear.

[0040] In the embodiment of the present invention, when the third transmission rod 13 rotates, the second transmission rod 12 is driven to rotate through the first transmission chain 14, and when the second transmission rod 12 rotates, the stepping gear 17 is driven to rotate through the cooperation of the transmission bar 1201 and the transmission groove 1701. The function of the transmission groove 1701 and the transmission bar 1201 is that when the second transmission rod 12 rotates, the stepping gear 17 is driven to rotate synchronously, and the stepping gear 17 can slide along the axial direction of the second transmission rod 12, and does not deviate from the synchronous rotation during the sliding period; when the stepping gear 17 rotates The gas cylinder movable rod 1103 of the gas cylinder 11 is driven by the transmission component to move toward the gas outlet end, so that the gas is injected into the storage box 5 through the piston inside it and the No. 1 delivery pipe 501, so that the positive pressure inside the storage box 5 is increased, and when the electric solenoid valve is opened, the liquid inside is sprayed into the culture piece 3; wherein, the movement stroke of the gas cylinder movable rod 1103 is the amount of positive pressure applied to the storage box 5, and the transmission ratio between the stepping gear 17 and the transmission component can be adjusted by the adjustment component to achieve the purpose of adjusting the stroke of the gas cylinder movable rod 1103.

[0041] Furthermore, the thickness of the first gear 1001 is the thickness of the teeth of the stepping gear 17 which increases / decreases gradually. For example, the thickness of the stepping gear 17 increases / decreases gradually by 3 cm each time, and the thickness of the first gear 1001 is 3 cm.

[0042] The adjustment assembly includes a bidirectional screw rod 9 rotatably mounted on one side of the No. 2 support plate 4, and the bidirectional screw rod 9 is sleeved with two threaded sleeves 901 that are threadedly matched with it. A transmission plate 902 is rotatably mounted on the two threaded sleeves 901, and the transmission plate 902 is rotatably connected to the stepping gear 17; the bidirectional screw rod 9 is connected to the No. 2 transmission rod 12 or the No. 3 transmission rod 13 through a synchronous belt.

[0043] In an embodiment of the present invention, when the third transmission rod 13 or the second transmission rod 12 rotates, the bidirectional screw rod 9 is driven to rotate through the synchronous belt. When the bidirectional screw rod 9 rotates, the two threaded sleeves 901 are driven to move in relative / opposite directions through the threaded cooperation with the two threaded sleeves 901; when the two threaded sleeves 901 move in opposite directions, the transmission plate 902 drives the two stepping gears 17 to follow the movement, thereby adjusting the transmission with the transmission assembly, and the adjustment method will be described in detail in the subsequent transmission assembly; wherein, the synchronous belt in the present invention is not shown in the figure.

[0044] The transmission assembly includes two No. 1 transmission rods 10 rotatably mounted on opposite sides of two receiving plates 15, and a No. 1 gear 1001 is coaxially fixed to the opposite ends of the two No. 1 transmission rods 10, and the No. 1 gear 1001 cooperates with the stepping gear 17; a No. 2 gear 1002 is also coaxially fixed on the two No. 1 transmission rods 10, and the No. 2 gear 1002 is meshed with a rack groove 1104 opened at the bottom of the air cylinder active rod 1103; a guide rod 1101 fixed to the air cylinder active rod 1103 is slidably mounted on one side of the air cylinder active rod 1103, and a spring 1102 is sleeved on the guide rod 1101.

[0045] In the embodiment of the present invention, when the stepping gear 17 rotates, it drives the No. 1 gear 1001 and the No. 1 transmission rod 10 to rotate, and when the No. 1 transmission rod 10 rotates, it drives the No. 2 gear 1002 to rotate synchronously. When the No. 2 gear 1002 rotates, it drives the cylinder movable rod 1103 to move through the rack groove 1104 meshing therewith, so as to add pressure to the storage box 5. When the cylinder movable rod 1103 moves, it also drives the guide rod 1101 to move, and at the same time compresses the spring 1102, so that the spring 1102 reserves a certain amount of elastic potential energy. When the No. 1 gear 1001 is out of mesh with the stepping gear 17, the elastic potential energy of the spring 1102 is released to drive the guide rod 1101 and the cylinder movable rod 1103 to reset; please refer to Figures 8 to 12 , since the length of the teeth of the stepping gear 17 is set to increase / decrease, when the stepping gear 17 is moving, the number of teeth of the stepping gear 17 meshing with the No. 1 gear 1001 will be gradually adjusted; for example, before adjustment, the stepping gear 17 rotates one circle through three of its racks and meshes with the No. 1 gear 1001 and drives the No. 1 gear 1001 to rotate a certain angle. After adjustment, six teeth are meshed with the No. 1 gear 1001, and so on. The transmission between the No. 1 gear 1001 and the stepping gear 17 will gradually increase as the position of the stepping gear 17 is adjusted; the effect achieved is that the more the angle / number of circles the No. 1 gear 1001 rotates, the greater the movement stroke of the cylinder active rod 1103 will be, and then the increase in the storage box 5 will be increased. The amount of pressure will be greater, and the adjustment of the stepping gear 17 is based on the rotation of the two-way screw 9, and the rotation of the two-way screw 9 is driven by the rotation of the No. 3 transmission rod 13, and the rotation of the No. 3 transmission rod 13 will be meshed with the No. 1 rack plate 203 through the incomplete gear 16. In other words, the No. 2 support plate 4 is intermittent and equidistant. At the same time, the amount of pressurization into the storage box 5 is gradually adjusted. The amount of pressurization corresponds to the liquid nutrient solution sprayed through the No. 2 delivery pipe 502, so as to add liquid to the culture piece 3 in turn, and the amount added each time is quantitatively increased based on the amount added last time. For example, 30g is added for the first time, 60g for the second time, 90g for the third time, and 120g for the fourth time.

[0046] A controller 6 is fixed to one side of the second support plate 4 , and the ultrasonic transmitter 7 and the motor 8 are electrically connected to the controller 6 via wires.

[0047] In an embodiment of the present invention, the controller 6 is connected to a computer, and the electronic equipment and components required to be driven and controlled involved in the present invention are not limited to the ultrasonic transmitter 7 and the motor 8, and the remaining components required to be driven and controlled are all electrically connected to the controller 6.

[0048] Embodiment 3, this embodiment is another way to replace the stepping gear 17, and its distinguishing feature is that: the pressure component also includes a gear roller 20, and the gear roller 20 is circumferentially equidistantly provided with a plurality of teeth 2001, and the plurality of teeth 2001 are all slidably connected to the gear roller 20, and the plurality of teeth 2001 are each provided with a threaded hole, and a screw rod 2002 with a threaded fit is installed inside the plurality of teeth 2001, and the screw rod 2002 is rotatably connected to the gear roller 20; two limit rollers 200 are rotatably installed at one end of the gear roller 20 3 and a transmission plate 2005, a plurality of screw rods 2002 and the transmission plate 2005 and the limiting roller 2003 are connected by a No. 2 transmission chain 2004, a No. 3 gear 2007 is rotatably mounted on one side of the No. 2 support plate 4, the No. 3 gear 2007 cooperates with a No. 2 rack plate 2008 fixed on the No. 1 support plate 2, and the No. 3 gear 2007 and the transmission plate 2005 are connected by a No. 3 transmission chain 2006; wherein the pitch of the plurality of screw rods 2002 gradually increases along one direction.

[0049] In the embodiment of the present invention, the No. 3 transmission chain 2006 between the No. 3 gear 2007 and the transmission disk 2005 is installed / removed according to the actual use situation; when the No. 3 transmission chain 2006 is installed, when the No. 2 support plate 4 moves, the No. 3 gear 2007 is driven to follow the movement, and the No. 3 gear 2007 rotates when it is meshed with the No. 2 rack plate 2008. When the No. 3 gear 2007 rotates, the transmission disk 2005 is driven to rotate through the No. 3 transmission chain 2006. When the transmission disk 2005 rotates, the plurality of lead screws 2002 are synchronously driven to rotate. The lead screws 2002 synchronously drive the plurality of teeth 2001 toward the transmission disk 2005 through the thread matching with the thread, and because the pitch of the lead screw 2002 is gradually increased, that is to say, the speed of movement is increased. The degree gradually increases, so that after the transmission plate 2005 rotates a specified number of times, multiple teeth 2001 all move to the end of the stroke, so that the tooth roller 20 and the tooth 2001 form a complete "gear"; when replacing the stepping gear 17 through this embodiment, the installation is kept consistent, and the transmission groove 1701 is set in the tooth roller 20 to sleeve the tooth roller 20 on the No. 2 transmission rod 12, but the difference is that when this implementation method is adopted, the adjustment component does not need to work, and then the synchronous belt between the two-way screw rod 9 and the No. 2 transmission rod 12 or the No. 3 transmission rod 13 needs to be removed; in summary, when this implementation method is adopted, the synchronous belt between the two-way screw rod 9 and the No. 3 transmission rod 13 or the No. 2 transmission rod 12 needs to be removed, and the No. 3 transmission chain 2006 needs to be installed at the same time.

[0050] The present invention also provides an ecological agricultural seedling cultivation experimental method based on physical ultrasonic detection, which uses the ecological agricultural seedling cultivation experimental device based on physical ultrasonic detection, including the following steps: Step 1, planting the seedlings in the culture piece 3, and then installing the culture piece 3 on the No. 1 support plate 2, and arranging them equidistantly; Step 2, driving the No. 2 support plate 4 and the storage box 5 to move equidistantly through the cooperation of the pressurizing component and the equidistant translation component, and adding nutrient solution to the culture piece 3 intermittently and equidistantly; Step 3, the added nutrient solution is gradually increased / decreased by a specified amount by the pressurizing component.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
