Description

Technical Field

[0001] This invention relates to the field of planting and cultivation equipment technology, specifically to a soil moisture control and supply device for chili cultivation. Background Technology

[0002] Chili peppers are neither drought-tolerant nor waterlogging-tolerant, and their water requirements vary at different growth stages. Seed germination requires sufficient water absorption, so the soil should be kept at a suitable moisture level. In current agricultural production, soil moisture management mainly relies on traditional irrigation methods (such as drip irrigation, sprinkler irrigation, or manual irrigation). Traditional drip irrigation or sprinkler irrigation is difficult to achieve uniform control of local soil moisture, which can easily lead to uneven moisture levels in the root zone. Especially given the shallow and dense root system of chili peppers, this can cause root rot or drought stress. Irrigation methods also have low water permeability, resulting in large soil runoff and evaporation losses, especially in sandy soils where water is easily lost through infiltration, leading to insufficient utilization.

[0003] In addition, traditional drip irrigation and sprinkler irrigation equipment lacks a flexible liquid mixing system. Nutrient solution and water are mixed. Most irrigation equipment needs to be equipped with an additional stirring device to mix water and nutrient solution, which consumes a lot of energy and has poor mixing uniformity. It is impossible to adjust the irrigation of water and nutrient solution as needed, which reduces the nutrient utilization rate of chili cultivation.

[0004] Based on the above reasons, we proposed a soil moisture control and supply device for chili cultivation. Summary of the Invention

[0073] Working principle:

[0074] The device prepares clean water or nutrient solution through the supply device 10, delivers the water to the irrigation device 30 through the water delivery device 40, and finally uniformly penetrates the water into the soil in the cultivation device 20 through the irrigation device 30, so as to realize precise moisture control. The components work together to form a closed-loop system of "water source preparation-delivery-irrigation-soil moisture retention".

[0075] Water source preparation and mixing: The mixing box 101 is internally provided with a conical mixing cavity 105 with a large top and a small bottom, the cavity is a spiral cavity, and the bottom is connected with a deposition cavity 106. The nutrient cartridge 102 and the clean water cartridge 103 independently store nutrient solution and clean water, the top is connected with the mixing cavity 105 through a connecting pipe, and a suction pump is arranged at the connection. The mixing box discharge valve 104 is provided with a pressurized delivery pump at the bottom, which is connected with the water delivery device 40.

[0076] The clean water is directly connected with the switching valve 403 through the clean water cartridge 103 bottom drain valve without mixing. The nutrient solution is pumped into the mixing cavity 105 by the suction pump according to the proportion of the nutrient solution and the clean water, the liquid flows spirally downward along the spiral cavity, collides and fuses by the centrifugal force and gravity, forms a uniform mixed liquid, and finally deposits in the deposition cavity 106, which is pressurized and delivered to the water delivery device 40 through the mixing box discharge valve 104.

[0077] Water source distribution and delivery: The water pump 401 provides power to deliver the liquid of the supply device 10 to each irrigation device 30 through the delivery pipe 404. The two connecting heads 402 of the switching valve 403 are respectively connected with the clean water cartridge 103 and the mixing box discharge valve 104, and the clean water / nutrient solution is switched by the valve.

[0078] The delivery pipe 404 is horizontally arranged above the cultivation box 201 and is deviated to one side to avoid the growth space of the pepper seedlings, and is connected with the irrigation water inlet head 305 through the adapter pipe 405.

[0079] After the water pump 401 is started, the switching valve 403 selects the water source according to the demand, the liquid flows into the irrigation water inlet head 305 through the delivery pipe 404 and the adapter pipe 405, and is injected downward into the irrigation cotton 310.

[0080] Water penetration and soil irrigation: The frame plate 301 is a back-shaped frame, the bottom and both sides are provided with limiting grooves 308, the sealing plate 302 is inserted into the side slot 306, the irrigation plate 303 is inserted into the middle slot 307, the irrigation cotton 310 is installed in the irrigation plate 303, and the top is fixed by the cover plate 311.

[0081] After the infiltration device 30 is fixed, the soil is filled in the space between the infiltration devices 30, and the pepper seedlings are planted in the soil; the liquid of the water delivery device 40 flows into the infiltration cotton 310 through the infiltration water inlet head 305, and is uniformly penetrated to the surrounding soil through the capillary action of the infiltration cotton 310. Water and nutrient supply through direct contact with the soil can reduce the probability of water evaporation, and at the same time can improve the water absorption efficiency of the pepper seedlings;

[0082] The replacement principle of the infiltration cotton 310 is that the pull handle 304 is connected with the push plate 315 through the screw joint 317, and the old infiltration cotton 310 can be pushed out upward; the new infiltration cotton 310 is guided and installed through the connecting rod 316. Insert the sealing plate 302 and the infiltration plate 303, and after being fixed, the sealing plate 302 is pulled out, so that the infiltration plate 303 is in contact with the soil, and the installation is completed.

[0083] When the infiltration cotton 310 is replaced, the pull handle 304 drives the push plate 315 to extrude the old infiltration cotton 310 to discharge the remaining water, which can improve the water utilization rate.

[0084] During the cultivation of pepper seedlings, the infiltration cotton 310 does not need to be replaced during the cultivation period, and can be replaced after the cultivation is completed or continued to be used after the soil is cleaned; the material of the infiltration cotton 310, such as natural fiber (service life of 3-6 months), synthetic fiber (service life of 1-2 years), and high molecular water gel (service life of 6-12 months), does not need to be replaced halfway; the infiltration device 30 needs to be installed in the cultivation box 201 first, and then the soil is filled.

[0085] The growth cycle of pepper seedlings is divided into two kinds, the complete growth cycle (from sowing to harvesting) is 90-120 days, and the transplanting growth cycle (from sowing to transplanting) is 40-60 days. After the cultivation is completed, the soil in the cultivation box 201 is easy to be hardened (water is difficult to penetrate, the surface is hardened) and salinized (the surface is white and crystallized), the structure is damaged, and if it is continued to be used, it will cause the new crop to grow slowly and the leaves to turn yellow, so it is usually necessary to replace or treat, and the replacement of the soil is the most convenient method;

[0086] The above two growth cycles do not need to replace the infiltration cotton 310 halfway, and the replacement method described in the scheme is carried out when there is no soil, and the replacement principle is not disturbed by the soil.

[0087] The foregoing illustrates and describes embodiments of the present application. However, it is to be understood that the application is not limited to the above-described embodiments, and that various changes and modifications can be suggested to one skilled in the art.
