Description

Technical Field

[0001] The invention relates to the technical field of planting equipment, in particular to a spray device for barley germination. Background Art

[0002] Barley germination is a process that requires demanding environmental conditions. Humidity requirements vary at different stages of germination. In the early stages of germination, the seeds require higher humidity to activate internal physiological processes and promote germination. As the malt grows, the humidity requirement decreases moderately in the middle stages. Finally, in the late stages of germination, humidity needs to be further reduced to prevent malt rot caused by excessive humidity.

[0003] Traditional barley germination equipment often has difficulty in accurately controlling environmental conditions such as humidity, temperature, and ventilation. Some devices may not be able to provide precise humidity regulation for different stages of barley germination, resulting in low germination rates or uneven malt quality. In terms of temperature control, there is a lack of effective heating and cooling methods to cope with changes in different ambient temperatures. Moreover, in the ventilation design, there may be problems with insufficient oxygen supply or poor carbon dioxide discharge.

[0004] Furthermore, existing spray equipment often lacks the flexibility to adjust spray parameters, such as spray height, nozzle specifications, and spray flow rate, based on the actual growth conditions of the barley. This can result in uneven spraying, waste water resources, and even damage to barley seeds or malt due to improper spraying, affecting the success rate and quality of germination. Summary of the Invention

[0011] The spray control strategy formulation module calculates and analyzes the humidity value of each monitoring point in each cultivation chamber corresponding to each monitoring period, and obtains the spray flow adjustment amount of each monitoring point in each cultivation chamber corresponding to each monitoring period.

[0012] Furthermore, a feeding trough is provided inside the cultivation rack, and a plurality of water leakage mesh holes are provided at the bottom of the inner wall of the feeding trough.

[0013] Furthermore, a micro motor is fixedly provided on one side of the mounting frame, and gears are fixedly provided on the output shaft of the micro motor and one end of the spray rack, and the tooth surfaces of the two gears are meshed for transmission.

[0014] Furthermore, a water inlet channel is provided on one side of the mounting frame, and the interior of the water inlet channel is respectively connected to the interior of several detachable spray card blocks, and the water inlet channel and the channels connecting the interiors of several detachable spray card blocks are both provided with automatic switching valves.

[0015] Furthermore, a sliding block is slidingly provided on the back of the mounting frame, and one side of the sliding block is connected to one end of the water supply flexible pipe. The back of the sliding block is also connected to a water-conducting spring tube, and the interior of the water-conducting spring tube is connected to the interior of the water supply flexible pipe through the sliding block. A spring is fixedly provided on one side of the back of the mounting frame, and one end of the spring is fixedly connected to the other side of the sliding block. One end of the water-conducting spring tube extends to the back of the incubator.

[0016] Furthermore, a drainage chute is provided inside the partition, and collection pipes are fixedly provided on both sides of the back side of the partition, and the upper ends of the two collection pipes are connected to the low-level side inside the drainage chute. A water tank is also movably provided at the bottom of the incubator, and the interior of the water tank is connected to the bottom ends of the two collection pipes.

[0018] Furthermore, the calculation and analysis is performed based on the humidity value corresponding to each monitoring point in each incubation chamber and each monitoring period. The specific calculation and analysis method is as follows:

[0019] The humidity threshold is set according to the germination status of the barley in each cultivation chamber. The humidity value of each monitoring point in each cultivation chamber corresponding to each monitoring period collected by real-time monitoring is calculated with the set humidity threshold to obtain the humidity deviation of each monitoring point in each cultivation chamber corresponding to each monitoring period, which is recorded as SPij. At the same time, the corresponding spray flow change is obtained according to the empirical correspondence table between humidity deviation and spray flow change, which is recorded as ΔQ. The maximum spray flow rate is determined according to the selected atomizing nozzle, which is recorded as Q max ; Wherein, i = 1, 2, ..., n, i represents the number of each monitoring point, n represents the total number of monitoring point numbers, j = 1, 2, ..., m, j represents the number of each monitoring period, m represents the total number of monitoring period numbers;

[0021] The integral time constant for eliminating steady-state errors is set based on historical experience, recorded as JT. The spray integral coefficient K for each monitoring point in each incubation chamber and each monitoring period is obtained by comparing the spray proportional coefficient for each monitoring point in each incubation chamber and the integral time constant for eliminating steady-state errors. i ;

[0022] By extracting the humidity values ​​at different time points from the monitored data, and then calculating the humidity deviation change rate by numerical difference method, the humidity deviation change rate of each monitoring point in each incubation chamber corresponding to each monitoring period is obtained, which is recorded as SBij;

[0023] The spray flow rate at each monitoring time point is measured in real time by a flow sensor installed inside the water-conducting spring tube. The difference between the spray flow rate values ​​at monitoring time points t1 and t2 is calculated and divided by the time interval between t1 and t2 to obtain the spray flow rate change rate for each monitoring point in each incubation chamber and each monitoring period, which is recorded as PLij.

[0024] According to the formula Calculate the spray differential coefficient K for each monitoring point in each incubation chamber and each monitoring period d ;

[0025] Finally, according to the formula Calculate the spray flow adjustment amount QTij for each monitoring point in each incubation chamber and each monitoring period. If the spray flow adjustment amount QTij for a monitoring point in a certain incubation chamber and a monitoring period is a positive number, it means that the spray flow in the incubation chamber corresponding to the monitoring point in the detection period is increased by QTij. Otherwise, it means that the spray flow in the incubation chamber corresponding to the monitoring point in the detection period is reduced by QTij.

[0026] The beneficial effects achieved by the present invention using the above structure are as follows:

[0027] 1. In the present invention, the interior of the incubator is divided into several incubation chambers by a number of partitions. Each incubation chamber can form a relatively stable microenvironment, which facilitates the individual regulation of humidity, temperature, ventilation and other conditions, and is conducive to accurately meeting the needs of barley at different growth stages, thereby improving the overall success rate and quality consistency of barley germination.

[0028] 2. By filling the discharge trough inside the cultivation rack with soil and burying barley seeds, and then slidingly connecting the two sides of the cultivation rack between the two connecting slide rails, the cultivation rack is flexibly installed inside the cultivation chamber.

[0029] 3. When spraying the barley seeds inside the cultivation rack, the movable rack is driven by the linear slide rail to slide back and forth directly above the cultivation rack. The spray rack inside the mounting rack and the spray structure formed by the detachable spray card and the atomizing nozzle are used to spray the barley seeds inside the cultivation rack. The height of the mounting rack is adjusted by the linear slide rail 2 according to the germination status of the barley, so that the spray component can flexibly adjust the spray status according to malt in different germination status, thereby greatly improving the success rate of barley germination.

[0030] 4.

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 making creative efforts are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0044] Example 1:

[0045] See also Figures 1 to 8 As shown, a spray device for barley germination includes a cultivation box 1. The interior of the cultivation box 1 is fixedly provided with a plurality of partitions 2 arranged vertically. The plurality of partitions 2 divide the interior of the cultivation box 1 into a plurality of cultivation chambers 3. The front surfaces of the plurality of cultivation chambers 3 are rotatably provided with a flip cover 4. A controller 26 is also fixedly provided on the right side of the cultivation box 1. Each cultivation chamber 3 can form a relatively stable microenvironment, which facilitates the individual regulation of humidity, temperature, ventilation and other conditions, thereby facilitating the precise meeting of the needs of barley at different growth stages, thereby improving the overall success rate and quality consistency of barley germination. A discharge assembly is provided in each of the cultivation chambers 3, and a spray assembly 7 is provided above the discharge assembly.

[0046] Specifically, the discharge assembly includes a cultivation rack 6, and connecting slide rails 5 are fixedly provided on the left and right sides of the inner wall of the cultivation chamber 3, and a cultivation rack 6 is slidably provided between the two opposite sides of the connecting slide rails 5, wherein a discharge trough is provided inside the cultivation rack 6, and a plurality of water leakage mesh holes are provided at the bottom of the inner wall of the discharge trough; by filling the discharge trough inside the cultivation rack 6 with soil and burying barley seeds, and then slidingly connecting the two sides of the cultivation rack 6 between the two connecting slide rails 5, the flexible installation of the cultivation rack 6 inside the cultivation chamber 3 is completed, and the cultivation rack 6 can be flexibly installed in the cultivation chamber 3 through the connecting slide rails 5, which facilitates the discharge and material removal operations. The water-leakage mesh at the bottom of the discharge trough can discharge excess water in time to prevent the barley from becoming moldy or rotting due to water accumulation, maintain the air permeability and appropriate humidity of the soil and barley seeds in the cultivation rack 6, provide good physical conditions for the germination of the barley seeds, and help to improve the germination rate; finally, the front of the cultivation chamber 3 is sealed by turning the cover plate 4, so that the barley seeds can be germinated in an independent and closed cultivation chamber 3, and independent spray control is performed according to the germination state of the barley in different cultivation chambers 3, thereby greatly improving the spray control effect during the barley germination process and improving the barley germination success rate.

[0047] Specifically, the spray assembly 7 includes a mounting frame 11 and a spray frame 12. Linear slide rails 8 are fixedly provided on the left and right sides of the inner wall of the cultivation chamber 3, and movable frames 9 are slidably provided on the opposite sides of the two linear slide rails 8. Linear slide rails 10 are fixedly provided on the opposite sides of the two movable frames 9, and a mounting frame 11 is slidably provided between the opposite sides of the two linear slide rails 10. The linear slide rails 10 can adjust the height of the mounting frame 11 and adjust the spray height according to the different germination states of the barley. For example, in the early stage of germination, the malt is shorter, and the spray height can be appropriately lowered to make the droplets fall on the seeds more accurately; As the malt grows, the spray height is increased to ensure that the droplets can evenly cover the malt. This flexible height adjustment can improve the spray effect and promote the healthy growth of barley. A spray rack 12 is rotatably provided inside the mounting frame 11, and a micro motor 15 is fixedly provided on one side of the mounting frame 11. The output shaft of the micro motor 15 and one end of the spray rack 12 are fixedly provided with gears, and the tooth surfaces of the two gears are meshed for transmission. The spray rack 12 is controlled to rotate inside the mounting frame 11 by the output shaft of the micro motor 15 using the gears that mesh with each other, so that nozzles of different specifications and sizes can be selected.

[0048] Furthermore, a plurality of detachable spray blocks 13 are clamped on the outer peripheral surface of the spray rack 12, and a plurality of atomizing nozzles 14 are fixedly provided on one side of the plurality of detachable spray blocks 13, wherein the atomizing nozzles 14 provided on each detachable spray block 13 have different atomizing diameter specifications. The atomizing nozzles 14 with corresponding atomizing diameter specifications are operated according to the germination state of the barley. The atomizing nozzles 14 with different atomizing diameter specifications are provided on the detachable spray block 13, and suitable nozzles can be selected according to the different stages of barley germination. In the early stage of germination, nozzles with finer atomizing diameters are used to gently cover the seeds with water to avoid damaging the seeds; in the late stage of germination, nozzles with slightly coarser atomizing diameters are used to ensure that water can penetrate into the malt layer to meet its growth needs. This diversified selection of nozzles improves the adaptability and accuracy of the spray, and helps to improve the success rate of barley germination.

[0049] Furthermore, a water inlet channel 27 is provided on one side of the mounting frame 11, and the interior of the water inlet channel 27 is respectively connected to the interior of several detachable spray blocks 13. The water inlet channel 27 and the channels connecting the interiors of several detachable spray blocks 13 are all provided with automatic switching valves. At each time, the barley can only be sprayed through the detachable spray block 13 and the atomizing nozzle 14 facing directly downward on the spray rack 12, avoiding the waste of water resources and ensuring the accuracy of the spray, so that the barley in each cultivation chamber 3 can get an appropriate amount of water supply.

[0050] Furthermore, a sliding block 16 is slidably provided on the back of the mounting frame 11, and one side of the sliding block 16 is connected to one end of the water supply flexible tube 17. A water-conducting spring tube 18 is also connected to the back of the sliding block 16, and the interior of the water-conducting spring tube 18 is connected to the interior of the water supply flexible tube 17 through the sliding block 16. A spring 19 is fixedly provided on one side of the back of the mounting frame 11, and one end of the spring 19 is fixedly connected to the other side of the sliding block 16. One end of the water-conducting spring tube 18 extends to the back of the incubator 1;

[0051] It should be noted that when spraying the barley seeds inside the cultivation rack 6, the movable rack 9 is driven by the linear slide rail 18 to slide back and forth directly above the cultivation rack 6, and the spray rack 12 inside the mounting rack 11 and the spray structure formed by the detachable spray block 13 and the atomizing nozzle 14 are used to spray the barley seeds inside the cultivation rack 6. The height of the mounting rack 11 is adjusted by the linear slide rail 2 10 according to the germination state of the barley, so that the spray component 7 can flexibly adjust the spray state for malt in different germination states, thereby greatly improving the success rate of barley germination.

[0052] Furthermore, a drainage chute 23 is provided inside the partition 2, and collecting pipes 24 are fixedly provided on both sides of the back side of the partition 2, and the upper ends of the two collecting pipes 24 are connected to the low-level side inside the drainage chute 23. A water storage tank 25 is also movably provided at the bottom of the incubation box 1, and the interior of the water storage tank 25 is connected to the bottom ends of the two collecting pipes 24; the water dripping from the inside of the incubation rack 6 is automatically collected by the drainage chute 23 provided inside the partition 2, and sent to the inside of the water storage tank 25 for centralized storage, avoiding excess water accumulation inside the incubation chamber 3, which not only avoids the adverse effects of excess water accumulation in the incubation chamber 3 on barley growth, but also realizes the recycling of water resources and saves water, while reducing the workload of manual cleaning of accumulated water, thereby improving the practicality and convenience of the device.

Electric heating wires are fixedly provided on the bottom of the several partitions 2 and the top of the inner wall of the cultivation box 1. The electric heating wires are used to increase the temperature of the barley during germination to meet the temperature requirements of barley germination, especially in cold weather or when the ambient temperature is low, to ensure that the barley can germinate within a suitable temperature range, thereby improving the germination efficiency and quality; in conjunction with the ventilation racks 22 on both sides and the air inlet duct 20 and the exhaust duct 21, the temperature of the barley during germination is lowered and regulated, and ventilation control is achieved inside the cultivation chamber 3 at the same time, so that air circulation in the cultivation chamber 3 can be achieved, ensuring that the barley has sufficient oxygen supply during the germination process, while discharging carbon dioxide produced by respiration, maintaining a good gas environment, and being conducive to aerobic respiration and normal growth of the barley.

[0054] In summary, the barley germination spray device proposed in the present invention provides suitable environmental conditions for barley germination in all aspects, including the division of the cultivation space, the material discharge and spraying method, the drainage system, and the ventilation and heating control, through the careful design of various structures. It can significantly improve the success rate and quality of barley germination, and at the same time has the advantages of easy operation and resource conservation, and has high practicality and innovation.

[0055] Example 2:

[0056] See also Figure 9 As shown, specifically, this embodiment is a further explanation of the spray control in the above embodiment 1. The controller 26 is further provided with a cultivation state parameter acquisition module and a spray control strategy formulation module;

[0057] The cultivation state parameter acquisition module monitors and collects data on the humidity values ​​corresponding to each monitoring point in each cultivation chamber 3 and each monitoring period through a plurality of humidity sensors distributed inside each cultivation chamber 3, and obtains the humidity values ​​corresponding to each monitoring point in each cultivation chamber 3 and each monitoring period;

[0058] The spray control strategy formulation module calculates and analyzes the humidity value of each monitoring point in each cultivation chamber 3 and each monitoring period, and obtains the spray flow adjustment amount of each monitoring point in each cultivation chamber 3 and each monitoring period. The specific calculation and analysis method is as follows:

[0059] The humidity threshold is set according to the germination state of the barley in each cultivation chamber 3. For example, in the early germination stage, since the seeds require a higher humidity to start the germination process, the relative humidity threshold range can be set to 80%-90%; in the middle germination stage, as the malt grows, the humidity requirement is slightly lower, and the threshold range is adjusted to 70%-80%; in the late germination stage, in order to prevent the malt from rotting, the humidity is further reduced, and the threshold range is set to 60%-70%;

[0060] The humidity value of each monitoring point in each cultivation chamber 3 corresponding to each monitoring period collected by real-time monitoring is calculated by difference calculation with the set humidity threshold value to obtain the humidity deviation of each monitoring point in each cultivation chamber 3 corresponding to each monitoring period, which is recorded as SPij. At the same time, according to the empirical correspondence table between humidity deviation and spray flow rate change, the corresponding spray flow rate change is obtained, which is recorded as ΔQ. The maximum spray flow rate is determined according to the selected atomizing nozzle 14, which is recorded as Q max ; Wherein, i=1,2,…,n, i represents the number of each monitoring point, n represents the total number of each monitoring point number, j=1,2,…,m, j represents the number of each monitoring period, m represents the total number of each monitoring period number.

[0061] According to the formula Calculate the spray ratio coefficient K of each monitoring point in each incubation chamber 3 corresponding to each monitoring period p ;

[0062] The integral time constant for eliminating steady-state errors is set based on historical experience, denoted as JT. The spray integral coefficient K for each monitoring point in each monitoring period in each incubation chamber 3 is obtained by comparing the spray proportional coefficient and the integral time constant for eliminating steady-state errors. i ;

[0063] By extracting the humidity values ​​at different time points from the monitored data, and then calculating the humidity deviation change rate by the numerical difference method, the humidity deviation change rate of each monitoring point in each incubation chamber 3 corresponding to each monitoring period is obtained, which is recorded as SBij;

[0064] The spray flow rate at each monitoring time point is measured in real time by a flow sensor installed inside the water-conducting spring tube 18. The difference between the spray flow rate values ​​at monitoring time points t1 and t2 is calculated and divided by the time interval between t1 and t2 to obtain the spray flow rate change rate for each monitoring point in each incubation chamber 3 and each monitoring period, which is recorded as PLij.

[0065] According to the formula Calculate the spray differential coefficient K of each monitoring point in each incubation chamber 3 corresponding to each monitoring period d ;

[0066] Finally, according to the formula Calculate the spray flow adjustment amount QTij for each monitoring point in each incubation chamber 3 and each monitoring period. If the spray flow adjustment amount QTij for a monitoring point in a monitoring period in a certain incubation chamber 3 is a positive number, it means that the spray flow in the corresponding monitoring point in the incubation chamber 3 during the detection period is increased by QTij. Otherwise, it means that the spray flow in the corresponding monitoring point in the incubation chamber 3 during the detection period is reduced by QTij.

[0067] In a specific embodiment, the present invention provides a humidity sensor inside each cultivation chamber, which can accurately monitor the humidity value of each cultivation chamber at different time periods, providing a data basis for subsequent precise control. Based on these humidity data, the spray control strategy formulation module can set a humidity threshold according to the different humidity requirements of barley at different germination stages, for example, the humidity threshold in the early germination stage is 80%-90%, etc.; by calculating the difference between the real-time humidity value and the threshold to obtain a humidity deviation, and then combining it with an empirical correspondence table to obtain the spray flow change, and considering the maximum spray flow of the atomizing nozzle, the spray ratio coefficient is calculated. The method of setting the humidity threshold in stages according to the germination state of the barley can ensure that there is a suitable humidity environment at each stage of barley germination, meet its growth needs, and improve the germination success rate;

[0068] In addition, the integral time constant is set according to historical experience, and the spray integral coefficient is obtained by comparing it with the spray proportional coefficient. At the same time, the humidity deviation change rate is calculated using the numerical difference method, and the spray flow change rate is measured by the flow sensor to calculate the spray differential coefficient. Finally, the spray flow adjustment amount of each cultivation chamber in each monitoring period is calculated according to the relevant formula. The spray flow rate can be flexibly adjusted according to the actual humidity conditions of each cultivation chamber, avoiding the adverse effects of excessively high or low humidity on barley germination. Whether increasing or decreasing the spray flow rate, it can be precisely controlled to ensure that the barley in each cultivation chamber can grow in a suitable humidity environment. At the same time, factors such as the elimination of steady-state errors and the spray flow change rate are taken into consideration, realizing scientific, efficient and precise spray control, greatly improving the controllability and success rate of the barley germination process.
