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 has relatively strict requirements on environmental conditions. In terms of humidity, barley has different requirements for humidity at different stages of germination. In the early stage of germination, the seeds need higher humidity to activate internal physiological activities and promote germination. As the malt grows, the humidity requirement is moderately reduced in the middle stage. In the late stage of germination, in order to prevent the malt from rotting due to too high humidity, the humidity needs to be further reduced.

[0003] Traditional barley germination equipment often finds it difficult to accurately control 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 rate 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 ventilation design, there may be problems with insufficient oxygen supply or poor carbon dioxide discharge.

[0004] In addition, in terms of spraying devices, existing equipment is usually unable to flexibly adjust spraying parameters according to the actual growth status of barley, such as spraying height, nozzle specifications and spraying flow rate, etc. This may cause uneven spraying, waste of water resources, and even damage 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 feed trough is arranged inside the cultivation rack, and a plurality of water leakage mesh holes are arranged at the bottom of the inner wall of the feed trough.

[0013] Furthermore, a micro motor is fixedly arranged on one side of the mounting frame, and gears are fixedly arranged 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.

[0019] The humidity threshold is set according to the germination state of 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, according to the empirical correspondence table of humidity deviation and spray flow change, the corresponding spray flow change is obtained, which is recorded as ΔQ.

[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.

[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.

[0029] 3. When spraying the barley seeds inside the cultivation rack, the movable rack is driven by the linear slide rail 1 to slide back and forth directly above the cultivation rack, and the spray structure formed by the spray rack inside the mounting rack and the detachable spray block and the atomizing nozzle is coordinated to spray the barley seeds inside the cultivation rack.

[0046] Specifically, the material discharge component 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 the cultivation rack 6 is slidably provided between the two opposite sides of the two connecting slide rails 5, wherein a material 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 material discharge trough; by filling the material 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 respectively, the cultivation rack 6 is flexibly installed inside the cultivation chamber 3, and the cultivation rack 6 can be flexibly installed in the cultivation chamber 3 through the connecting slide rails 5, which facilitates the material discharge and material retrieval operations. The water-leakage mesh at the bottom of the discharge trough can discharge excess water in time to prevent the barley from getting moldy or rotting due to water accumulation, maintain the air permeability and suitable 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 closed by turning the cover plate 4, so that the barley seeds can be in an independently closed cultivation chamber 3 for germination treatment, 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 10 are fixedly provided on the opposite sides of the two movable frames 9, and mounting frames 11 are 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 raised 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 arranged inside the mounting frame 11, and a micro motor 15 is fixedly arranged 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 arranged with gears, and the tooth surfaces of the two gears are meshed for transmission. The output shaft of the micro motor 15 uses the gears that mesh with each other to control the spray rack 12 to rotate inside the mounting frame 11, so that nozzles of different specifications and sizes can be selected.

The atomizing nozzles 14 with different atomizing diameter specifications are arranged on the detachable spray block 13, and suitable nozzles can be selected according to different stages of barley germination. In the early stage of germination, nozzles with finer atomizing diameters are used to allow water to gently cover the seeds and avoid damage to 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 nozzle selection improves the adaptability and accuracy of the spray, and helps to improve the success rate of barley germination.

[0050] Further, 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 pipe 17, and a water guide spring pipe 18 is also connected to the back of the sliding block 16, and the interior of the water guide spring pipe 18 is connected to the interior of the water supply flexible pipe 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, and one end of the water guide spring pipe 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 8 to slide back and forth just 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 cooperated to spray the barley seeds inside the cultivation rack 6, and the height of the mounting rack 11 is adjusted by the linear slide rail 10 according to the germination state of the barley, so that the spray component 7 can flexibly adjust the spray state of 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 side inside the drainage chute 23. A water storage tank 25 is also movably provided at the bottom of the cultivation 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 cultivation 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, so as to avoid the accumulation of excess water inside the cultivation chamber 3, which not only avoids the adverse effect of the accumulation of excess water in the cultivation chamber 3 on the growth of barley, 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 bottoms of the plurality of partitions 2 and the tops of the inner walls of the cultivation box 1. The temperature of the barley during germination is increased and regulated by the electric heating wires 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 and improve the germination efficiency and quality; the temperature of the barley during germination is decreased and regulated in cooperation with the ventilation racks 22 on both sides and the air inlet duct 20 and the exhaust duct 21, and ventilation control inside the cultivation chamber 3 is realized at the same time, so that air circulation in the cultivation chamber 3 can be realized, ensuring that the barley has sufficient oxygen supply during the germination process, and at the same time, discharging carbon dioxide produced by respiration, maintaining a good gas environment, and being conducive to aerobic respiration and normal growth of barley.

At the same time, it has the advantages of easy operation and resource saving, and has high practicality and innovation.

[0055] Embodiment 2:

[0056] See also Fig. 9 As shown, specifically, this embodiment is a further description of the spray control in the above-mentioned embodiment 1, and 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 ​​of each monitoring point and each monitoring period in each cultivation chamber 3 through a plurality of humidity sensors distributed inside each cultivation chamber 3, and obtains the humidity values ​​of each monitoring point and each monitoring period in each cultivation chamber 3;

[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 corresponding to each monitoring point in each cultivation chamber 3 and each monitoring period collected by real-time monitoring is calculated by difference with the set humidity threshold value, and the humidity deviation corresponding to each monitoring point in each cultivation chamber 3 and each monitoring period is obtained, which is recorded as SPij. At the same time, according to the empirical correspondence table of humidity deviation and spray flow change, the corresponding spray flow change is obtained, which is recorded as ΔQ. The maximum spray flow 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 numbers of each monitoring point, j=1,2,…,m, j represents the number of each monitoring period, m represents the total number of numbers of each monitoring period.

[0061] According to the formula Calculate the spray ratio coefficient K of each monitoring point in each cultivation 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 corresponding to each monitoring point in each monitoring period in each incubation chamber 3 is obtained by comparing the spray proportional coefficient corresponding to each monitoring point in each incubation chamber 3 with 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 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 the monitoring time points t1 and t2 is calculated and then divided by the time interval between t1 and t2 to obtain the spray flow rate change rate at each monitoring point in each cultivation 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 certain incubation chamber 3 and a monitoring period 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 can accurately monitor the humidity value of each cultivation chamber at different time periods by arranging a humidity sensor inside each cultivation chamber, thereby providing a data basis for subsequent precise control. Based on these humidity data, the spray control strategy formulation module can set the humidity threshold according to the different humidity requirements of barley at different germination periods, for example, the humidity threshold at the initial germination stage is 80%-90%, etc.; the humidity deviation is obtained by performing a difference calculation between the real-time humidity value and the threshold, and then the spray flow rate change is obtained by combining the empirical corresponding table, and the maximum spray flow rate of the atomizing nozzle is considered, and then the spray ratio coefficient is calculated. The method of setting the humidity threshold in stages according to the germination state of 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 by 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 considered to achieve scientific, efficient and precise spray control, which greatly improves the controllability and success rate of the barley germination process.
