Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural power machinery technology, specifically to an intelligent detection track-type rice breeding fertilizer applicator and its breeding rack. Background Technology

[0002] Rice breeding is a core technological support for strengthening national food security, promoting sustainable agriculture, and increasing farmers' income. Modern breeding focuses on the integration of multiple genes, such as high yield, high quality, disease and pest resistance, and stress tolerance, to continuously improve the yield, yield stability, and resource utilization efficiency of new varieties. However, in large-scale breeding facilities, the concentration of the culture medium is an "invisible lever" that determines the uniformity and potential of seedlings: too high a concentration can easily "burn" the seedlings, while too low a concentration can cause stunted growth, both of which make it difficult to fully express the gene potential.

[0003] Actual operation revealed that the primary factor causing the low concentration was not the formula, but the delivery system. In order to achieve uniform liquid distribution in the breeding tank, the nozzle orifice was designed to be extremely fine: it can accurately control the amount and form a layered fine flow covering the entire width of the tank. However, the nozzle is immersed in the culture medium for a long time, and inorganic salts and organic matter repeatedly crystallize and deposit inside and outside the micropores, which can easily cause blockage, resulting in local interruption of liquid supply and the formation of "concentration depressions" in the tank.

[0004] Existing technologies typically involve equidistantly spaced concentration probes within the tank. When a concentration at a certain point is detected to be below a threshold, a backup nozzle is switched on. The blind spot of this strategy is that the number of probes is limited. When blockage occurs between the probes but has not yet affected the location of the probes, the system cannot detect it in time, and the concentration difference is continuously amplified, ultimately leading to uneven growth of seedlings in the same batch. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent detection track-type rice breeding fertilizer applicator and its breeding rack to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0011] An elastic trigger assembly is connected to the linear drive module. The elastic trigger assembly is provided with a first convex shaft that can move within the retaining groove. The trigger assembly has two states: energy storage and energy release. In the energy release state, the first convex shaft can cooperate with the retaining groove to drive the transmission structure to move.

[0012] An electric telescopic rod is connected to the linear drive module and electrically connected to the intelligent concentration detection device installed in the breeding trough. The electric telescopic rod can drive the elastic trigger component to move.

[0013] As a further embodiment of the present invention: a drive plate is fixed on the linear drive module, a sliding groove is provided on the drive plate, and a slider connected to the pump assembly is slidably installed in the sliding groove;

[0014] The slider is rotatably mounted with abutting wheels, which roll in cooperation with guides located on both sides of the breeding trough, thereby driving the slider to move upward.

[0015] As a further embodiment of the present invention: the pumping assembly includes a pumping device and a connecting pipe fixedly connected to the linear drive module, and a cylindrical connector is provided at one end of the connecting pipe away from the pumping device. The drainage channel is disposed in the cylindrical connector and communicates with the connecting pipe.

[0016] The rotating component includes a connecting seat that rotates and fits with the cylindrical connector, and the drainage channel can guide the culture medium through the connecting seat into one of the sets of nozzles.

[0017] As a further embodiment of the present invention: the transmission structure includes a gear fixedly connected coaxially to the connecting seat and a rack plate meshing with the gear, wherein the rack plate is provided with a guide groove and the retaining groove;

[0018] The two sets of grooved wheels mounted on the linear drive module can roll within the guide groove.

[0019] As a further embodiment of the present invention: the elastic triggering component includes:

[0020] A pressure feedback structure is connected to the connecting pipe, and one end of the pressure feedback structure is provided with a hook part;

[0021] An energy storage structure connected to the linear drive module, wherein the energy storage structure is provided with a second convex shaft and a first convex shaft, and the hook portion is capable of driving the energy storage structure to move.

[0022] A side plate is mounted on the linear drive module. The side plate is provided with a guide groove, which is rolledly connected to the second cam shaft.

[0023] As a further embodiment of the present invention: the pressure feedback structure includes a connecting sleeve fixedly installed on the linear drive module, the connecting sleeve being connected to the connecting pipe, and a sealing plug being slidably installed inside the connecting sleeve, the sealing plug being provided with a first hook plate penetrating the connecting sleeve, and the hooking part being formed at the end of the first hook plate away from the sealing plug.

[0024] As a further embodiment of the present invention: the energy storage structure includes a transverse frame disposed on the linear drive module, the transverse frame being provided with a sliding connection portion and the first convex shaft, the sliding connection portion being able to slide within a guide member connecting the linear drive module;

[0025] The energy storage structure also includes a vertical groove arranged along the length of the transverse frame, and a lifting component is slidably installed in the vertical groove. The lifting component is rotatably connected to the second convex shaft.

[0026] A vertical shaft is also provided in the vertical groove, and a cylindrical spring is sleeved on the vertical shaft. One end of the cylindrical spring is connected to the end of the vertical groove, and the other end is connected to the lifting component.

[0027] As a further embodiment of the present invention: the guide groove includes an inverted "V" shaped groove disposed on the side plate, and the cylindrical spring can be compressed when the second convex shaft moves from the "V" shaped groove toward the center.

[0028] A breeding rack, including the aforementioned intelligent detection track-type rice breeding fertilizer applicator, further includes:

[0029] The support frame has multiple sets of breeding troughs installed on it, and adjacent sets of breeding troughs are spatially staggered.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] This allows the switching of the nozzles to be controlled by two methods: concentration detection control and pressure change control. The two work together to maintain the consistency of the culture solution concentration in the breeding tank to the greatest extent possible, ensuring the consistent growth and development of rice seedlings and providing a stable culture solution supply system for breeding.

[0032] With the designed elastic triggering component, firstly, although slight pressure changes in the connecting pipe will cause the first hook plate to move, as long as the pressure in the connecting pipe does not reach the preset value, the elastic force provided by the cylindrical spring can reset the first hook plate, thereby reducing the occurrence of false triggering. Secondly, in the energy storage state, the elastic force provided by the cylindrical spring can act in the opposite direction on the sealing plug, so that the pressure in the connecting pipe remains increased, and under the action of pressure, there is a probability of pushing out the crystallized material in the nozzle, thus having a certain self-clearing effect. At the same time, if clearing cannot be achieved, the nozzle can also automatically switch to prevent the pipeline from leaking due to excessive pressure. In addition, the nozzle can ensure the stability of the culture medium addition to the greatest extent by rapidly rotating and switching, ensuring that the culture medium concentration in the breeding tank is consistent.

Detailed Implementation

[0043] 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.

[0044] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0045] Please see Figures 1-9 In this embodiment of the invention, an intelligent detection track-type rice breeding fertilizer applicator is installed on the side of the breeding trough 2, and includes: a pump assembly, a rotating component, a transmission structure, an elastic trigger assembly, and an electric telescopic rod 25.

[0046] The pump assembly is connected to the linear drive module 3 located on the side of the breeding tank 2, and the outlet end of the pump assembly is provided with a drainage channel 1001.

[0047] The linear drive module 3 is fixed with a drive plate 4, and the drive plate 4 is provided with a slide groove 401. A slider 6 connected to the pump assembly is slidably installed in the slide groove 401.

[0048] The slider 6 is rotatably mounted with an abutment wheel 7. The abutment wheel 7 rolls in cooperation with the guides 5 arranged on both sides of the breeding trough 2, which can drive the slider 6 to move upward. Specifically, the end of the guide 5 is provided with an inclined part 501, which can guide the abutment wheel 7 to move upward.

[0049] In this embodiment, in the initial state, the abutting wheel 7 is on the guide 5. At this time, the abutting wheel 7 and the guide 5 cooperate to make the slider 6 be in the upper part of the slide groove 401. In this state, the rotating nozzle 12 is above the liquid surface of the culture medium in the breeding tank 2. That is, when the nozzle 12 does not add culture medium to the breeding tank 2, the nozzle 12 will not combine with calcium and magnesium ions and carbonates in the culture medium due to long-term immersion in the culture medium, and form calcium sulfate or calcium carbonate crystals inside and outside the nozzle 12. This reduces the speed at which the nozzle 12 is blocked, and makes its speed when adding culture medium to the breeding tank 2 more uniform.

[0050] Furthermore, when it is necessary to add culture medium into the breeding tank 2, the linear drive module 3 is controlled to move. At this time, the drive plate 4 can drive the slider 6 to move along the length direction of the breeding tank 2, and the abutment wheel 7 can move along the inclined part 501, so that the slider 6 moves downward. At the same time, the nozzle 12 can be immersed in the culture medium in the breeding tank 2 to perform the culture medium injection action.

[0051] Please see Figures 5-7 The pumping assembly includes a pumping device 8 and a connecting pipe 9 fixedly connected to the linear drive module 3. A cylindrical connector 10 is provided at one end of the connecting pipe 9 away from the pumping device 8. The drainage channel 1001 is disposed in the cylindrical connector 10 and communicates with the connecting pipe 9. The connecting pipe 9 is connected to the pumping device 8 through a flexible hose.

[0052] The rotating component is rotatably connected to the pump assembly, and two sets of nozzles 12 are detachably mounted on the rotating component;

[0053] The rotating component includes a connecting seat 11 that rotatably engages with the cylindrical connector 10, and the drainage channel 1001 can guide the culture medium through the connecting seat 11 into one of the sets of nozzles 12.

[0054] In use, the connecting seat 11 can rotate relative to the cylindrical connecting head 10, and the connecting seat 11 is provided with two sets of liquid outlets. The two sets of liquid outlets are connected to two sets of nozzles 12 through conduits. In the initial state, only one set of nozzles 12 can be submerged below the surface of the culture medium in the breeding tank 2, while the other set of nozzles 12 is above the surface of the culture medium in the breeding tank 2. When the nozzles 12 below the surface of the culture medium in the breeding tank 2 become blocked due to crystallization, the elastic trigger component and transmission structure will be activated, thereby switching the positions of the two sets of nozzles 12. This allows the unblocked nozzles 12 to quickly switch to the surface of the culture medium in the breeding tank 2, thus ensuring the continuity of culture medium addition and preventing uneven distribution of culture medium in the breeding tank 2, which would lead to inconsistent growth of rice seedlings.

[0055] For example, the angle formed by the connecting seat 11 to the two sets of nozzles 12 is preferably 180° or 90°. When the angle is 180°, the connecting seat 11 will rotate 180° when the two sets of nozzles 12 are switched. At this time, the blocked nozzle 12 after switching is at the highest point of its stroke, which makes it convenient for maintenance personnel to disassemble and clean it.

[0056] When the angle is 90°, the connecting seat 11 will rotate 90° when the two sets of nozzles 12 are switched. At this time, when the nozzle 12 moves to the end of the stroke along with the linear drive module 3, the horizontally placed blocked nozzle 12 can be directly inserted into the cleaning device (not shown in the figure) set on the side of the breeding tank 2, thereby realizing the automatic cleaning of the blocked nozzle 12 by the cleaning device.

[0057] Please see Figure 5 , Figures 7-8 The transmission structure is connected to the connecting seat 11, and the transmission structure is provided with a retaining groove 1402;

[0058] The transmission structure includes a gear 13 coaxially and fixedly connected to the connecting seat 11 and a rack plate 14 meshing with the gear 13. The rack plate 14 is provided with a guide groove 1401.

[0059] The two sets of grooved wheels 15 mounted on the linear drive module 3 can roll within the guide groove 1401.

[0060] When the elastic trigger component is activated, it can drive the rack plate 14 to move laterally. At this time, the rack plate 14 and the gear 13 are in a meshing state, causing the connecting seat 11 to rotate, thereby realizing the position switching of the two sets of nozzles 12. Specifically, in this embodiment, the connecting seat 11 is provided with two sets of connection ports. In the initial state, the drainage channel 1001 is in communication with one set of connection ports, so that when the culture medium is pumped into the connecting pipe 9, it can enter the nozzle 12 located below through the drainage channel 1001. During the rotation of the connecting seat 11, the two sets of connection ports will be misaligned with the drainage channel 1001. When the other set of connection ports coincides with the drainage channel 1001, the culture medium can be pumped towards the other set of nozzles 12, thereby realizing the addition of the culture medium.

[0061] The elastic trigger component is connected to the linear drive module 3. The elastic trigger component is provided with a first convex shaft 1601 that can move within the retaining groove 1402. The trigger component has two states: energy storage and energy release. In the energy release state, the first convex shaft 1601 can cooperate with the retaining groove 1402 to drive the transmission structure to move.

[0062] The elastic trigger component includes:

[0063] A pressure feedback structure is connected to the connecting pipe 9. One end of the pressure feedback structure is provided with a hooking part. Specifically, the pressure feedback structure includes a connecting sleeve 22 fixedly installed on the linear drive module 3. The connecting sleeve 22 is connected to the connecting pipe 9, and a sealing plug 23 is slidably installed inside the connecting sleeve 22. A first hook plate 24 is provided on the sealing plug 23, which penetrates the connecting sleeve 22. The hooking part is formed at the end of the first hook plate 24 away from the sealing plug 23.

[0064] When the nozzle 12 below the culture medium level in the breeding tank 2 becomes blocked during use, the pressure in the connecting pipe 9 increases due to the continuous operation of the pumping device 8. At this time, the connecting sleeve 22 is connected to the connecting pipe 9, and under the pressure, the sealing plug 23 moves along the inside of the connecting sleeve 22, which in turn drives the first hook plate 24 to move. When the first hook plate 24 moves, it can drive the energy storage structure into the energy storage state. When the energy storage structure enters the energy release state, it drives the transmission structure to operate, thereby realizing the switching of the two sets of nozzles 12. That is, the switching of nozzles 12 depends on the pressure in the connecting pipe 9.

[0065] An energy storage structure connected to the linear drive module 3 is provided with a second convex shaft 2001. The energy storage structure includes a transverse frame 16 provided on the linear drive module 3. The transverse frame 16 is provided with a sliding connection part 1602 and the first convex shaft 1601. The sliding connection part 1602 can slide within the guide member 17 connected to the linear drive module 3.

[0066] The energy storage structure also includes a vertical groove arranged along the length of the transverse frame 16, and a lifting component 20 is slidably installed in the vertical groove. The lifting component 20 is rotatably connected to the second convex shaft 2001.

[0067] A vertical shaft 19 is also provided in the vertical groove, and a cylindrical spring 18 is sleeved on the vertical shaft 19. One end of the cylindrical spring 18 is connected to the end of the vertical groove, and the other end is connected to the lifting component 20.

[0068] The side plate 21 is mounted on the linear drive module 3. The side plate 21 is provided with a guide groove, which is tactilely connected to the second convex shaft 2001. The guide groove includes an inverted "V" shaped groove on the side plate 21. When the second convex shaft 2001 moves from the "V" shaped groove toward the center, the cylindrical spring 18 can be compressed. The "V" shaped groove is composed of a first inclined groove 2101 and a second inclined groove 2102. The first inclined groove 2101 and the second inclined groove 2102 form a downwardly extending protrusion.

[0069] In the initial state, the second convex shaft 2001 is located at the end of the second inclined groove 2102 away from the first inclined groove 2101. At this time, the cylindrical spring 18 is in a compressed state, and the first convex shaft 1601 is located at one end of the holding groove 1402. When one set of nozzles 12 becomes blocked, the pressure in the connecting pipe 9 will increase, causing the transverse frame 16 to move laterally under the drive of the first hook plate 24, and causing the second convex shaft 2001 to move towards the protrusion along the length direction of the second inclined groove 2102. During this process, the cylindrical spring 18 is further compressed (i.e., in an energy-storing state), and The first convex shaft 1601 moves within the retaining groove 1402, keeping the rack plate 14 stationary. When the second convex shaft 2001 moves past the protrusion, the cylindrical spring 18 can actively release elastic potential energy (i.e., energy release state), driving the second convex shaft 2001 to move along the first inclined groove 2101. At this time, the first convex shaft 1601 moves to the end of the retaining groove 1402, so that when the second convex shaft 2001 moves along the first inclined groove 2101 and actively drives the transverse frame 16 to move laterally, the rack plate 14 will also drive the gear 13 to rotate, thereby driving the two sets of nozzles 12 to switch.

[0070] It should be noted that stop plates (not shown in the figure) are also provided on both sides of the rack plate 14. In the initial state, one side of the rack plate 14 abuts against the stop plate. At this time, the first convex shaft 1601 is in the holding groove 1402 near the end of the set of stop plates, so that the rack plate 14 is locked in this state, thereby improving the stability of the nozzle 12 in the initial state. Similarly, after the nozzle 12 is switched, the other side of the rack plate 14 abuts against another set of stop plates, and the first convex shaft 1601 is in the other side of the holding groove 1402, which can also lock the rack plate 14. This ensures that the nozzle 12 is in a stable state after the position is switched, and also prevents the nozzle 12 from rotating excessively.

[0071] Based on the above settings, firstly, although slight pressure changes in the connecting pipe 9 will cause the first hook plate 24 to move, as long as the pressure in the connecting pipe 9 does not reach the preset value, the elastic force provided by the columnar spring 18 can reset the first hook plate 24, thereby reducing the occurrence of false triggering. Secondly, in the energy storage state, the elastic force provided by the columnar spring 18 can act in the opposite direction on the sealing plug 23, so that the pressure in the connecting pipe 9 remains increased, and under the action of pressure, there is a probability of pushing out the crystallized material in the nozzle 12, thus having a certain self-unblocking effect. At the same time, if unblocking cannot be achieved, the nozzle 12 can also automatically switch to prevent the pipeline from leaking due to excessive pressure. In addition, the nozzle 12 can ensure the stability of the culture medium addition to the greatest extent by rapidly rotating and switching, ensuring that the concentration of the culture medium in the breeding tank 2 is consistent.

[0072] Please see Figure 5 , Figure 9 The electric telescopic rod 25 is connected to the linear drive module 3 and electrically connected to the intelligent concentration detection device (not shown in the figure) installed in the breeding trough 2. The moving end of the electric telescopic rod 25 is fixed with a second hook plate 26. When the electric telescopic rod 25 moves, the second hook plate 26 can drive the transverse frame 16 to move.

[0073] When the intelligent concentration detection device detects that the concentration of the culture medium in the breeding tank 2 is lower than the preset value, it sends the detection result signal to the electric telescopic rod 25, which can actively control the movement of the electric telescopic rod 25, so that the transverse frame 16 can move laterally under the pull of the second hook plate 26, thereby enabling the two sets of nozzles 12 to switch.

[0074] The intelligent concentration detection device is a combination of a refractometer and an intelligent control module. The refractometer is an application of existing technology, utilizing the critical angle measurement principle. It integrates a light source, a prism, and an image detector. By measuring the critical angle, it determines the refractive index of the liquid and then calculates the concentration parameter of the solution. The intelligent control module is a threshold intelligent comparison module. When the intelligent comparison module determines that the concentration parameter of the current culture medium is lower than the preset value, it sends a signal to the electric telescopic rod 25 to activate it.

[0075] Among them, the threshold intelligent comparison module is also a very mature existing technology. The programmable logic controller used in this application is based on the IEC61131-3 standard. It is an intelligent comparison module based on CODESYS comparison instructions. In the field of automation control, CODESYS provides a variety of comparison instructions for comparing numerical values, strings, arrays, etc.

[0076] With the above settings, the switching of nozzle 12 can be controlled by two methods, including concentration detection control and pressure change control. The two work together to maintain the consistency of the culture medium concentration in the breeding tank 2 to the greatest extent, ensuring the consistent growth and development of rice seedlings and providing a stable culture medium supply system for breeding.

[0077] Please see Figure 1 As an embodiment of the present invention, a breeding rack is also proposed, including the aforementioned intelligent detection track-type rice breeding fertilizer applicator, and further including: a support 1, on which multiple sets of the aforementioned breeding troughs 2 are installed, and adjacent sets of breeding troughs 2 are spatially staggered. By making adjacent sets of breeding troughs 2 spatially staggered, rice seedlings can obtain higher growth space and the overall height of the breeding rack can be lowered, so that the breeders can more easily observe the breeding situation. Moreover, the staggered arrangement can allow rice seedlings to obtain more sufficient light, which is more conducive to the growth of rice seedlings.

[0078] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0079] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
