Description

Technical Field

[0001] The invention relates to the field of plant cultivation, in particular to an intelligent root layer infiltration irrigation and fertilization system. Background Art

[0002] Plant cultivation requires fertilization to increase crop yield and quality, while protecting soil health. The main purpose of plant fertilization is to increase crop yield, improve crop quality, improve soil fertility and improve economic benefits. The basis for fertilization includes soil fertility level, crop type, target yield, climate environment and fertilizer characteristics, so as to select appropriate fertilizers, estimate the required fertilizer dosage, and determine the fertilization time and fertilization mode. According to the different fertilization time, it can be divided into base fertilizer and topdressing; according to the different fertilization modes, it can be divided into broadcasting, flushing, hole application, strip application, etc. Broadcasting and flushing are conducive to the diffusion of nutrients and are easy to apply, but the nutrient loss is large and the utilization rate is low; hole application and strip application have less nutrient loss and high utilization rate, but they consume a certain amount of mechanical energy. With the development of modern precision agriculture, precision fertilization has also developed rapidly and will become an important fertilization mode.

[0003] Fertilizers are divided into two types: solid waste and liquid fertilizers. Liquid fertilizers usually contain a large amount of essential nutrients, such as nitrogen, phosphorus, potassium, calcium, magnesium, iron, zinc, etc., and in order to meet the needs of crops at different growth stages, some liquid fertilizers also add ingredients such as amino acids, which help to improve the yield and quality of crops. In contrast, the nutrients in solid fertilizers are relatively single, and due to low utilization, the nutrients in them cannot be fully absorbed by crops, resulting in nutrient imbalance in the soil and affecting crop yields. Liquid fertilizers are superior to solid fertilizers in terms of nutrient richness, crop absorption, ease of use, and nutrient utilization. Therefore, liquid fertilizers are becoming more and more widely used, but the existing liquid fertilizers still have the following problems in plant cultivation:

[0004] At different growth stages of existing plants, the length of the roots of plants in the soil varies. Operators use nozzles to spray fluid fertilizers on the plants. During the spraying process, part of the fluid fertilizer is sprayed on the leaves of the plants and easily evaporates with the heat, resulting in a waste of the fluid fertilizer, while the remaining fluid fertilizer flows into the soil along the branches. Some plants with too long roots cannot absorb the fluid fertilizer, affecting the cultivation effect of the plants. Therefore, it is very necessary to involve an intelligent root layer infiltration and fertilization system for use in the existing plant cultivation field. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art, the root length of plants in the soil varies at different growth stages of existing plants. Operators use nozzles to spray fluid fertilizers on the plants. During the spraying process, part of the fluid fertilizer is sprayed on the leaves of the plants and easily evaporates with the heat, resulting in a waste of the fluid fertilizer, while the remaining part of the fluid fertilizer flows into the soil along the branches.

[0016] 1. The present invention controls the switch of the valve according to the position of the plant cultivated in the cultivation room on the cultivation box, so that the connection pipe controls the flow with the branch pipe, and according to the length of the plant root system, the cylinder is started, so that the piston rod drives the traction block to move downward, and the traction block drives the fixed block on the connection rod to move downward.

On the inner side of the compression spring 71, the guide block 63 is fixedly equipped with a horizontal block 72, the horizontal block 72 is fixedly equipped with an assembly block 73, the assembly block 73 is fixedly equipped with a liquid spray head 50, the inner wall of the operating chamber 13 is fixedly equipped with multiple groups of vertical blocks 51, each group of vertical blocks 51 has two, and the surface of the vertical block 51 is fixedly equipped with an arc block 52, the roller 70 is sequentially fitted with the surface of the vertical block 51 and the arc block 52, the cylinder 32 is started, so that the piston rod 33 drives the traction block 40 downward The traction block 40 drives the fixed block 42 on the connecting rod 41 to move downward. When the fixed block 42 moves downward, the roller 70 fits with the surface of the vertical block 51 and the arc block 52 in turn. When the roller 70 fits with the arc block 52, the roller 70 is stressed, so that the guide rod 62 moves on the fixed block 42, the telescopic spring 71 is telescoped, the guide block 63 drives the assembly block 73 on the horizontal block 72 to move back and forth, and the assembly block 73 drives the liquid spray head 50 to move back and forth.

[0042] Reference Figure 4 The inner wall of the operating room 13 is fixedly equipped with multiple water storage boxes 53, and the inner walls of the water storage boxes 53 are fixedly equipped with multiple partitions 60. The inner walls of the water storage boxes 53 are provided with multiple through holes 61, and the through holes 61 are located on one side of the partitions 60, and the through holes 61 are connected with the cultivation room 12. When the roller 70 and the arc block 52 are fitted, the spray head 50 is correspondingly located between the two water storage boxes 53, and one end of the spray head 50 is close to the through hole 61. When the roller 70 and the arc block 52 are fitted, it is convenient for liquid fertilizer to enter the water storage box 53 through the spray head 50, and then enter the cultivation room 12 through the through hole 61, so as to perform root layer infiltration irrigation on the plants cultivated in the cultivation room 12.

[0043] Reference Figure 1 and Figure 2 as well as Figure 6A connecting pipe 20 is fixedly mounted on the delivery pipe 10, and a plurality of connecting heads 21 are fixedly mounted on the connecting pipe 20. A branch pipe 23 is fixedly mounted on one end of the connecting head 21, and a hose 30 is fixedly mounted on one end of the branch pipe 23. One end of the hose 30 is fixedly mounted with the spray head 50. A valve 22 is mounted on the connecting head 21. According to the position of the plant cultivated in the cultivation chamber 12 on the cultivation box 11, the switch of the valve 22 is controlled so that the connection pipe 20 controls the flow with the branch pipe 23. The liquid fertilizer enters the connecting pipe 20 through the delivery pipe 10, enters the branch pipe 23 through the connecting pipe 20, and then enters the hose 30 through the branch pipe 23. Finally, the liquid fertilizer is sprayed into the water storage box 53 through the spray head 50. Since the water storage box 53 is separated into a plurality of through-holes 61 by a partition plate 60, the sprayed liquid fertilizer flows into the plant root system in the cultivation chamber 12 through the through-holes 61, thereby improving the use effect of the liquid fertilizer and avoiding the waste of the liquid fertilizer.

[0044] Working principle: According to the position of the plant cultivated in the cultivation chamber 12 on the cultivation box 11, the switch of the valve 22 is controlled, so that the connecting pipe 20 controls the flow with the branch pipe 23. According to the length of the plant root system, the cylinder 32 is started, so that the piston rod 33 drives the traction block 40 to move downward, and the traction block 40 drives the fixed block 42 on the connecting rod 41 to move downward. When the fixed block 42 moves downward, the roller 70 is sequentially fitted with the surface of the vertical block 51 and the arc block 52. When the roller 70 is fitted with the arc block 52, the roller 70 is stressed, so that the guide rod 62 moves on the fixed block 42, the telescopic spring 71 is extended and retracted, and the guide block 63 is moved downward. The assembly block 73 on the horizontal block 72 is driven to move back and forth, and the assembly block 73 drives the spray head 50 to move back and forth. When the roller 70 is fitted with the arc block 52, the liquid fertilizer enters the connecting pipe 20 through the delivery pipe 10, enters the branch pipe 23 from the connecting pipe 20, and then enters the hose 30 from the branch pipe 23. Finally, the liquid fertilizer is sprayed into the water storage box 53 through the spray head 50. Since the water storage box 53 is separated into multiple through holes 61 by the partition plate 60, the sprayed liquid fertilizer flows into the plant root system in the cultivation chamber 12 through the through hole 61, thereby improving the use effect of the liquid fertilizer and avoiding the waste of liquid fertilizer.

[0045] Example 2

[0046] like Figures 1 to 3As shown, it is a schematic diagram of the structure of an intelligent root layer infiltration fertilization system according to another preferred embodiment of the present invention. Liquid fertilizer enters the cultivation chamber 12 through the through-hole 61. Due to the low penetration efficiency of liquid fertilizer in the soil, the liquid fertilizer will also bring out a part of the soil and flow out to the water storage box 53 in the operating chamber 13, causing soil loss and reducing the operating effect. Therefore, based on Example 1, the device is improved, and a plurality of filter boxes 43 are fixedly installed on the inner wall of the cultivation chamber 12. The through-holes 61 are all located on the inner side of the filter boxes 43 at the connecting parts of the cultivation chamber 12, and the filter boxes 43 are all provided with infiltration holes.

[0047] Working principle: Liquid fertilizer infiltrates the plant roots in the cultivation chamber 12 through the infiltration holes on the filter box 43. The infiltration holes on the filter box 43 can block the soil from entering the water storage box 53, reducing soil loss and improving the operation effect on plant cultivation.

[0048] Example 3

[0049] like Figure 7 and Figure 8 As shown, it is a schematic diagram of the structure of an intelligent root layer infiltration fertilization system in another preferred embodiment of the present invention. The telescopic spring 71 is easily deformed after long-term use, which increases the replacement cost of the telescopic spring 71. Therefore, with the cooperation of Example 1 and Example 2, the device is improved. The fixed block 42 is movably equipped with a correction block 82, one end of the correction block 82 is fixedly equipped with a mounting block 83, one end of the mounting block 83 is fixedly equipped with an extension block 90 located above the fixed block 42, the surface of the extension block 90 is fixedly equipped with a traction rack 91, the other end of the correction block 82 is fixedly equipped with an operating plate 92, and the guide block 63 is fixedly equipped with a plurality of guide plates 93. A fixed plate 93 is fixedly mounted, and a first adjusting block 94 is movably mounted on the operating plate 92, and an assembly rod 96 is fixedly mounted on one end of the first adjusting block 94, and a second adjusting block 95 is movably mounted on the fixed plate 93, and one end of the second adjusting block 95 is movably assembled with the assembly rod 96 on the first adjusting block 94, and an operating block 80 is fixedly mounted on the bottom of the traction block 40, and an operating motor 81 is fixedly mounted on the operating block 80, and a rotating rod 97 is fixedly mounted on the output end of the operating motor 81, and the rotating rod 97 movably penetrates the operating block 80, and a plurality of transmission gears 98 corresponding to the tooth pattern assembled with the traction rack 91 are fixedly mounted on the rotating rod 97.

[0050] The work moves away, and the roller 70 is subjected to force, so that the distance between the fixed block 42 and the guide block 63 changes, and the assembly rod 96 on the first adjusting block 94 and the second adjusting block 95 move, and are gradually in a stretched state. When the telescopic spring 71 is stretched for a long time and causes deformation, the operating motor 81 is started, so that the rotating rod 97 drives the transmission gear 98 to rotate, and the transmission gear 98 drives the traction rack 91 to move, and the traction rack 91 drives the mounting block 83 on the extension block 90 to move, so that the correction block 82 moves on the fixed block 42, and the assembly rod 96 on the first adjusting block 94 and the second adjusting block 95 move, and are also gradually in a stretched state, so that the guide block 63 can move toward the fixed block 42, which helps to slow down the deformation of the telescopic spring 71, improve the service life, and reduce the cost of use.
