Description

Technical Field

[0001] This invention belongs to the field of vegetable planting technology, and in particular relates to an integrated fertilizer, water and air application device for vegetables. Background Technology

[0002] In the field of greenhouse vegetable cultivation, fertigation technology is of great significance for improving vegetable yield and quality and optimizing resource utilization efficiency. Currently, greenhouse vegetable cultivation methods are diverse, encompassing traditional soil cultivation, soilless cultivation using substrates such as peat moss and vermiculite, soilless cultivation with rock wool nutrient solutions, and organic ecological soilless cultivation. Irrigation methods primarily employ furrow irrigation and drip irrigation, while fertilization methods include nutrient solution application, manual application of solid fertilizer, or fertigation. During the greenhouse overwintering period, carbon dioxide supplementation is often achieved through methods such as gas cylinders, combustion, or chemical reactions.

[0003] In the field of integrated fertigation systems, most devices are temporarily assembled from independent components such as water pumps, filters, fertilizer tanks, venturi systems, and aeration equipment. This piecemeal structure has many drawbacks: First, the assembly and debugging of each component is complex, requiring significant manpower and time, and the connections are prone to leaks, leading to fertilizer, water, or gas leakage, which reduces the stability and reliability of the system. Second, the combination of independent components makes the entire device bulky and space-consuming, which undoubtedly increases the difficulty of layout for greenhouses with limited space. Third, the high cost of purchasing and maintaining multiple independent components greatly limits the widespread application of this technology among farmers.

[0004] Given the aforementioned shortcomings of existing integrated fertilizer, water, and air application devices for vegetables, there is an urgent practical need to develop a compact, stable, and low-cost integrated fertilizer, water, and air application device for vegetables. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a compact, stable and low-cost integrated fertilizer, water and air application device for vegetables.

[0006] Technical solution: A vegetable fertigation device comprising a mounting base, an irrigation pump, an irrigation pipeline, and a fertilizer storage mechanism. The mounting base is in the form of two steps, with the irrigation pump located at the edge of the lower step. The irrigation pipeline is connected to the irrigation pump, and the mounting base supports the irrigation pipeline. The fertilizer storage mechanism is located on the upper step of the mounting base and is connected to the irrigation pipeline. The fertilizer storage mechanism can continuously provide liquid fertilizer to the irrigation pipeline, and the irrigation pipeline can automatically draw the fertilizer and gas from the fertilizer storage mechanism into the irrigation pipeline. The irrigation pipeline has a filtration function.

[0007] In one embodiment, the irrigation pipeline includes an irrigation water pipe and, from left to right, a pressure relief valve, a Y-type filter, a Venturi tube I, a flow meter, a pressure gauge, and a Venturi tube II installed on the irrigation water pipe. The fertilizer storage mechanism is connected to the Venturi tube I, and the Venturi tube II is provided with an air inlet for connecting to the oxygenation module.

[0008] In one embodiment, the irrigation pipeline is also equipped with an air intake structure, which includes an air intake hopper, an air intake fan, a filter plate, and a one-way structure. The air intake hopper is connected to the air intake port of the Venturi tube II by a thread, and the bottom of the air intake hopper is recessed downwards. The air intake fan is installed on the top of the air intake hopper. The filter plate is disposed inside the air intake hopper, and the bottom of the air intake hopper is provided with a one-way structure, which prevents the liquid in the irrigation pipe from being discharged through the air intake port.

[0009] In one embodiment, the unidirectional structure includes a conical block and a spring. The conical block is slidably disposed in the lower part of the air intake hopper. The conical block retracts upward and blocks the opening at the bottom of the air intake hopper. The spring is connected between the bottom of the conical block and the air intake hopper.

[0010] In one embodiment, the fertilizer storage mechanism includes a support frame, a fertilizer storage tank, an inlet pipe, a Y-shaped connecting pipe, valves, a stirring motor, and stirring blades. The support frame is mounted on a stepped mounting base. There are two fertilizer storage tanks, symmetrically arranged on the support frame. Each fertilizer storage tank has an inlet pipe at its upper part, and the lower parts of the fertilizer storage tanks are connected by a Y-shaped connecting pipe. The common end of the Y-shaped connecting pipe is connected to and communicates with a Venturi tube I. There are two valves, located at the bifurcation of the Y-shaped connecting pipe. By opening the corresponding Y-shaped connecting pipe, the corresponding fertilizer storage tank is connected to the Venturi tube I. There are two stirring motors, each fixedly connected to the bottom of the fertilizer storage tank. The stirring blades are connected to the output shaft of the stirring motor and extend upward into the fertilizer storage tank. The connection between the stirring blades and the fertilizer storage tank is sealed.

[0011] In one embodiment, the fertilizer storage mechanism further includes a storage tank, a partition, a baffle plate, a gear ring, a feeding motor, and a pinion. The storage tank is located on top of the fertilizer storage tank, and a support frame supports the storage tank. The partition is located inside the storage tank and divides the storage tank into two equal spaces. Discharge holes are provided at the bottom of the storage tank on both sides of the partition, and the two discharge holes are equidistant from the axis of the storage tank. The baffle plate is rotatably located between the storage tank and the fertilizer storage tank. The baffle plate has a feeding hole, which can overlap or partially overlap with the discharge hole during rotation. A gear ring is circumferentially arranged on the outer side of the baffle plate. The feeding motor is located above the outer side of the fertilizer storage tank. The pinion is keyed to the output shaft of the feeding motor, and the pinion meshes with the gear ring.

[0012] In one embodiment, the device further includes a detachable filter and a mating nut. The detachable filter is connected to the bifurcation of the Y-shaped connecting pipe. Both ends of the detachable filter have external threads on their outer surfaces. The outer surface of the Y-shaped connecting pipe at the mating point with the detachable filter also has external threads. The mating nut is threaded to both ends of the detachable filter. When the detachable filter is mated with the Y-shaped connecting pipe, the mating nut is screwed onto the mating point of the external threads.

[0013] In one embodiment, the detachable filters are arranged in two groups, and are installed on the support frame at the Y-shaped connecting pipe. The two detachable filters in each group are rotatably connected by a shaft, and the positions of the two detachable filters can be interchanged.

[0014] Compared with the prior art, the present invention has the following advantages: the integrated installation of various modules provides great convenience during equipment maintenance; the irrigation pipeline ensures a continuous supply of liquid, and the fertilizer storage mechanism can achieve a continuous supply of fertilizer, improving the efficiency and quality of equipment operation; when the removable filter becomes clogged, the connecting nut is screwed onto the removable filter, and then the two removable filters are rotated 180° to interchange their positions, a new removable filter is installed, and the clogged removable filter is cleaned, further ensuring the sustainability of equipment operation.

Detailed Implementation

[0025] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0026] Please refer to the following: Figures 1-8 The present invention provides an integrated fertilizer, water, and air application device for vegetables. This integrated fertilizer, water, and air application device includes a mounting base plate 1, an irrigation pump 2, an irrigation pipeline 3, and a fertilizer storage mechanism 4. The mounting base plate 1 is in the form of two steps. The irrigation pump 2 is located on the top left side of the lower step, with an inlet on the left and an outlet on the right. The irrigation pipeline 3 is connected to the outlet on the right side of the irrigation pump 2. The mounting base plate 1 supports the irrigation pipeline 3. The irrigation pipeline 3 automatically draws fertilizer and gas from the fertilizer storage mechanism 4 into its interior through Bernoulli's principle. The irrigation pipeline 3 has a filtration function. The fertilizer storage mechanism 4 is located on the upper step of the mounting base plate 1 and is connected to the irrigation pipeline 3. The fertilizer storage mechanism 4 continuously provides liquid fertilizer to the irrigation pipeline 3.

[0027] This embodiment provides a vegetable fertilizer, water, and gas integrated application device. Compared with the prior art, the integrated installation of the device provides great convenience during equipment maintenance. When irrigation and fertilization are required, the fertilizer is first prepared in the fertilizer storage mechanism 4, and then the irrigation pump 2 is started to work. The irrigation pump 2 draws water into the irrigation pipeline 3. When the water passes through the irrigation pipeline 3, it is filtered and fertilizer and gas are added. Then it is discharged into the irrigation branch pipe to irrigate the vegetables. The continuous supply of fertilizer can ensure the efficiency of fertilization and improve the quality of fertilization.

[0028] In a preferred embodiment, the irrigation pipe 3 can be adopted as follows: Figure 2 The structure shown includes an irrigation pipe 31 and, from left to right, a pressure relief valve 32 for stabilizing the pressure inside the pipe, a Y-type filter 33 for filtering impurities and preventing pipe blockage and which is removable, a Venturi tube I 34 for accelerating the flow rate and reducing the fluid pressure to achieve negative pressure suction, a flow meter 35 for recording the liquid flow rate, a pressure gauge 36 for monitoring the pressure, and a Venturi tube II 37. The fertilizer storage mechanism 4 is connected to the Venturi tube I 34, and the Venturi tube II 37 is provided with an air inlet for connecting to the oxygenation module.

[0029] In a preferred embodiment, the intake structure 38 can adopt the following... Figures 3-5 As shown in the diagram, the irrigation pipe 3 is also equipped with an air intake structure 38, which includes an air intake hopper 381, an air intake fan 382, ​​a filter plate 383, and a one-way structure. The air intake hopper 381 is connected to the air inlet of the Venturi tube II 37 via threads. If the air intake hopper 381 becomes blocked, it can be unscrewed for unblocking. The bottom of the air intake hopper 381 is recessed downwards to accelerate the speed at which gas enters the irrigation pipe 3. The air intake fan 382 is installed on the top of the air intake hopper 381 to facilitate the intake of gas into the air intake hopper 381 and expand the intake area. The filter plate... 383 is installed inside the air inlet 381 to filter the inhaled gas and prevent the air inlet 381 from becoming clogged. The bottom of the air inlet 381 is provided with a one-way structure, which prevents the liquid in the irrigation pipe 31 from being discharged through the air inlet. The one-way structure includes a conical block 384 and a spring 385. The conical block 384 is slidably installed in the lower part of the air inlet 381. The conical block 384 retracts upward and blocks the opening at the bottom of the air inlet 381. The conical block 384 can only move downward. The spring 385 is connected between the bottom of the conical block 384 and the air inlet 381.

[0030] Irrigation pipe 3: Liquid enters irrigation pipe 31 through irrigation pump 2. If the pressure in the pipe is too high, it can be relieved through pressure relief valve 32. Liquid enters Venturi tube I 34 through Y-type filter 33. The liquid flow rate increases and negative pressure is generated, which draws the fertilizer in fertilizer storage device 4 into Venturi tube I 34. Then the liquid passes through Venturi tube II 37 again. The flow rate increases and negative pressure is generated, which pulls the cone block 384 downward. The spring 385 deforms. The outside gas is filtered through filter plate 383 and then enters Venturi tube II 37 through air inlet hopper 381, where it mixes with the liquid in Venturi tube II 37.

[0031] In a preferred embodiment, the fertilizer storage mechanism 4 can be adopted as follows: Figures 6-7The structure shown includes a fertilizer storage mechanism 4 comprising a support frame 41, fertilizer tanks 42, an inlet pipe 43, a Y-shaped connecting pipe 44, a valve 45, a stirring motor 46, and stirring blades 47. The support frame 41 is mounted on a stepped base plate 1. Two fertilizer tanks 42 are symmetrically arranged on the support frame 41. Each fertilizer tank 42 has an inlet pipe 43 at its upper part, which connects to an external liquid injection device via a flange. A Y-shaped connecting pipe 44 connects the lower parts of the fertilizer tanks 42, with the common end of the Y-shaped connecting pipe 44 connected to and communicating with a Venturi tube I 34. Fertilizer in the fertilizer tanks 42 is supplied via the Y-shaped connecting pipe 44. A Y-shaped connecting pipe 44 enters into a Venturi tube I 34; two valves 45 are located at the bifurcation of the Y-shaped connecting pipe 44, connecting the corresponding fertilizer storage tank 42 to the Venturi tube I 34 by opening the corresponding Y-shaped connecting pipe 44, and the two valves 45 do not open simultaneously; two stirring motors 46 are fixedly connected to the bottom of the fertilizer storage tank 42; stirring blades 47 are connected to the output shaft of the stirring motors 46 and extend upward into the fertilizer storage tank 42, with a sealed connection between the stirring blades 47 and the fertilizer storage tank 42, and the stirring blades 47 are rotated by controlling the rotation of the stirring motors 46. The fertilizer can be evenly mixed, while soluble fertilizers are dispersed to prevent pipe blockage. The fertilizer storage mechanism 4 also includes a storage tank 48, a partition 49, a baffle plate 411, a gear ring 413, a feeding motor 414, and a pinion 415. The storage tank 48 is located on top of the fertilizer storage tank 42 and is used to store fertilizers to be added later. The support frame 41 supports the storage tank 48. The partition 49 is located inside the storage tank 48 and divides the storage tank 48 into two equal spaces. The two spaces can store different types of fertilizers. The bottom of the storage tank 48 on both sides of the partition 49 is provided with a discharge hole 410. Each discharge hole 410 is equidistant from the axis of the storage tank 48; a baffle plate 411 is rotatably disposed between the storage tank 48 and the fertilizer storage tank 42, and a discharge hole 412 is provided on the baffle plate 411. The discharge hole 412 can overlap or partially overlap with the discharge hole 410 during rotation, so that fertilizer in the storage tank 48 can be added into the fertilizer storage tank 42. A gear ring 413 is provided on the outer circumferential side of the baffle plate 411; a feeding motor 414 is disposed above the outer side of the fertilizer storage tank 42; a pinion 415 is keyed to the output shaft of the feeding motor 414, and the pinion 415 meshes with the gear ring 413.

[0032] Fertilizer storage mechanism 4: During irrigation, fertilizer is added to two spaces within the storage tank 48. Depending on the type of fertilizer to be added, the feeding motor 414 rotates clockwise or counterclockwise, causing the baffle plate 411 to rotate clockwise or counterclockwise, which in turn rotates the feeding hole 412 clockwise or counterclockwise. The feeding hole 412 then aligns with different discharge holes 410, allowing fertilizer from the corresponding space to be released into the fertilizer storage tank 42. Simultaneously, the stirring motor 46 drives the stirring blades 47 to rotate, uniformly mixing the fertilizer within the storage tank 42. When the fertilizer is prepared and irrigation begins, as the liquid flows through the irrigation pipeline 3, valve 45 on one of the fertilizer storage tanks 42 is opened. The fertilizer in the storage tank 42 is then added to the irrigation pipeline 3 through the Y-shaped connecting pipe 44. After the fertilizer in the storage tank 42 is used up, valve 45 on the storage tank 42 is closed, and valve 45 on the other storage tank 42 is opened. Fertilizer is then prepared for the used storage tank 42. This process ensures a continuous supply of fertilizer, improving the efficiency and quality of the equipment.

[0033] In a preferred embodiment, the method may be as follows: Figures 8-9 The structure shown also includes a detachable filter 416 and a connecting nut 418. The detachable filter 416 is connected to the bifurcation of the Y-shaped connecting pipe 44 and is used to filter the outflowing fertilizer to prevent undissolved fertilizer from clogging the pipe. Both ends of the detachable filter 416 have external threads 417 on their outer surfaces, and the outer surface of the Y-shaped connecting pipe 44 at the joint with the detachable filter 416 also has external threads 417. The connecting nut 418 is threaded to both ends of the detachable filter 416. When the detachable filter 416 is connected to the Y-shaped connecting pipe 44, the connecting nut 418 is screwed onto the joint of the external threads 417. When the external thread 417 on 16 is engaged, the detachable filter 416 can be replaced. The detachable filters 416 are arranged in pairs, with a total of two pairs, which are respectively installed on the support frame 41 at the Y-type connecting pipe 44. The two detachable filters 416 in each pair are rotatably connected by a shaft, and the positions of the two detachable filters 416 can be interchanged. When the detachable filter 416 becomes clogged, the mating nut 418 is screwed onto the detachable filter 416, and then the two detachable filters 416 are rotated 180° to interchange their positions. Then, a new detachable filter 416 is installed, and the clogged detachable filter 416 is cleaned to further ensure the sustainability of the equipment operation.
