Description

Technical Field

[0001] The invention belongs to the technical field of automated planting, and in particular relates to a high-quality and high-yield planting system for sprout vegetables. Background Art

[0002] At present, the market demand for traditional sprout products is large, but the quality is low and unstable. There are problems such as the use of additives that are not conducive to food safety. The production method is mainly manual and simple machine substitution. In addition to soybean sprouts and mung bean sprouts, other production methods such as pea sprouts, garlic sprouts, leek sprouts, toon sprouts, and radish sprouts are all produced by manual and machine-assisted methods. Producers generally face the dilemma of high costs, low efficiency, and difficulty in survival. Even producers with a certain scale find it difficult to ensure stable product quality, which seriously affects the market size and market reputation. There is a serious gap between industrial development and the value of sprouts, and the development of the industry lags seriously behind market demand.

[0003] In addition, the existing sprout planting technology mainly adopts medium planting or fixed suspended planting. In order to improve the yield and quality of sprouts, groundwater is used for medium-free irrigation. Although these methods have improved the competitiveness of the products, there are also a series of problems that restrict their further efficient production and standardized planting. First of all, although the traditional fixed suspended planting has solved the problem of low space utilization to a certain extent, its planting structure usually relies on a fixed irrigation and lighting system. Pipes and sprinklers need to be distributed to each planting point, resulting in complex maintenance and high system costs. At the same time, the traditional suspended planting method lacks effective standardized control, and the spraying equipment is difficult to accurately adjust according to the specific needs of different planting areas. It is easy to have problems such as uneven water supply, insufficient or excessive light, which further affects the growth uniformity and yield of crops.

[0004] Secondly, although the use of groundwater has the advantages of low cost and constant temperature throughout the year, its hardness is greatly affected by seasonal and precipitation fluctuations. When the calcium and magnesium ion content in groundwater is high, the viscosity and surface tension of the water body increase, which will directly lead to an increase in the particle size of the droplets sprayed by the sprinkler. Large droplets are not easily absorbed by crops, which may lead to uneven irrigation effects and affect the growth of sprouts. When the water temperature drops, the viscosity of the water body increases further, which will also affect the atomization effect. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to provide a high-quality and high-yield planting system for sprouts, solve the problems of low efficiency, difficult maintenance, insufficient production standardization, etc. in the existing planting technology, and at the same time change the problem that the traditional spray system cannot effectively control the droplet particle size.

[0039] The working principle of the present technical solution is as follows: start the temperature / humidity control system 8 to adjust the temperature and humidity parameters in the planting workshop 1; confirm the normal operation of the annular hanging assembly line 2, the multi-level flat planting tray 3 and the equipment in each functional area for water replenishment, light replenishment, harvesting, etc.; the seeds are sent from the seed bank to the germination workshop, and the sprout seeds are evenly spread in the flat planting tray 31 by the automatic seeder, and stacked for germination; after germination, the flat planting tray 31 is transferred to the racking machine, and the racking machine puts the flat planting tray 31 on each layer of the tray of the single-column planting rack 32, the annular hanging assembly line 2 system is automatically started, and the multi-level flat planting tray 3 starts to move slowly along the set path; the system starts the water replenishment process according to the set time and conditions, and the self-adjusting atomizing nozzle 42 automatically adjusts the nozzle aperture according to the real-time detected water hardness, temperature and nutrient solution ratio to ensure the appropriate droplet particle size; the light replenishment equipment automatically adjusts the light intensity according to the growth stage and actual needs of the crop to ensure that each flat planting tray can receive uniform light; the automated control system monitors the environmental parameters and temperature of the planting space in real time , humidity, water quality, etc., and make corresponding adjustments to ensure the constancy and standardization of the sprout growth environment; if it is detected that the water hardness or temperature changes greatly, the system will automatically adjust the droplet size to ensure the effect of sprinkler irrigation; when the sprouts reach the harvesting conditions, the multi-level flat planting tray 3 automatically moves to the set harvesting point through the circular hanging assembly line 2; at the harvesting point, the automatic sprout harvester automatically picks the crops, harvests the sprouts of the same specifications and automatically divides them by weight, and sends them to the automatic packaging machine, and the packaged finished vegetables are put into the fresh-keeping warehouse; the flat planting tray 3 1 together with the residue (roots and residual stems of plants) are sent to the cleaning workshop, and the flat planting tray 31 and the residue are separated after cleaning. The flat planting tray 31 is disinfected and sent back to the germination room for recycling. The roots and residual stems of plants are dried and dehydrated in the drying workshop and then sent to the feed processing workshop; Through this system, the planting process of sprouts is highly automated, and the planting efficiency and yield are significantly improved. The system realizes dynamic adjustment of the droplet particle size through precise control of water hardness and nutrient solution concentration, ensuring the growth standardization and high yield of sprouts;

[0040] When adjusting the droplet particle size sprayed by the self-adjusting atomizing nozzle 42, the automatic control system receives and processes the water temperature signal and the water hardness signal, as well as the data signal of different viscosities generated by the different ingredients of the preset water body, and controls the running state of the servo motor 24. The servo motor 24 drives the driving gear 23 to rotate, so that the driving gear 23 engages and drives the driven gear 22 to rotate, and the driven gear 22 drives the adjusting section 12 to rotate, and a spiral pair motion is generated between the rotating adjusting section 12 and the connecting section 11, thereby driving the moving section 13 to move. When the moving section 13 moves, the nozzle end of the adjustable nozzle can be adjusted. 21. The variable spiral plate 18 releases elastic potential energy or is elastically deformed by being squeezed. When the adjustable nozzle end 21 is deformed, the minimum inner diameter of the adjustable nozzle end 21 changes, thereby changing the inner hole of the water nozzle of the new mist spray area 4, thereby changing the droplet particle size; when the variable spiral plate 18 is deformed, the change of the spiral angle of the variable spiral plate 18 and the change of the width and depth of the spiral plate groove will cause the droplet particle size to change accordingly. The function of the spiral plate is to guide the fluid to produce rotational motion inside the nozzle. The rotational motion can increase the turbulence of the fluid, thereby promoting the breakup and atomization of the liquid.
