Description

Technical Field

[0001] The invention patent relates to the technical field of agricultural irrigation and fertilization, and specifically, to a water-saving irrigation and fertilization device for agricultural planting. Background Art

[0002] In the development of modern agriculture, irrigation and fertilization technology is a key factor in improving the yield and quality of agricultural crops, and it is also the core focus of agricultural scientific research and practice. Traditional agricultural irrigation and fertilization methods mainly rely on extensive modes of artificial fertilizer spreading and flooding. The traditional method not only causes uneven distribution of fertilizers, but also makes it difficult to accurately meet the differentiated nutrient needs of crops at different growth stages, which can easily cause soil nutrient imbalance, local excess or deficiency of fertility, and seriously affect the healthy growth and uniform development of crops; and a large amount of water resources are also wasted ineffectively, and the irrigation efficiency is extremely low. At the same time, it causes a series of serious problems such as soil compaction, nutrient loss and environmental pollution, which greatly restricts the sustainable development of agriculture.

[0003] With the development of agricultural modernization, many irrigation and fertilization technologies have emerged, bringing innovative opportunities for agricultural production. However, an in-depth analysis of the various irrigation and fertilization equipment on the current market shows that there are still many defects that need to be overcome. For example: some equipment in the existing technology lacks precise dosage control and uniform distribution mechanism in the fertilization process, resulting in significant differences in fertilizer content in various parts of the field and uneven crop growth. This not only reduces the overall quality of agricultural products, but also increases the management costs and operating risks of growers; some other equipment has failed to fully consider the diversity of different crop varieties and planting spacing in design, and it is difficult to flexibly adjust the fertilization layout and irrigation range, which greatly reduces its applicability when facing complex and changeable agricultural planting scenarios, and cannot effectively meet the actual production needs of farmers.

[0004] At the same time, many existing devices also perform poorly in terms of water-saving performance. For example, the water spraying range is narrow and the spraying uniformity is poor, resulting in a large amount of water resources failing to effectively cover the crop root area, causing serious waste. It is also impossible to create a stable and suitable moisture environment for the crop roots, greatly weakening the growth vitality and stress resistance of crops. What is particularly critical is that most equipment fails to properly coordinate the contradictory relationship between the mobility and operational stability of the device in the overall structural design. In actual agricultural production, it is difficult to balance the frequent equipment movement requirements with the high-precision, continuous and stable irrigation and fertilization operation requirements, which makes the equipment easily damaged and the accuracy reduced during frequent movement, seriously affecting the operating efficiency and equipment life, and indirectly pushing up the cost of agricultural production.

[0005] In addition, existing technologies have significant shortcomings in achieving coordinated operation of sprinkler irrigation and fertilization. Most equipment is difficult to accurately and in real time regulate the amount of sprinkler irrigation water and the dosage and frequency of fertilization according to the dynamic water and fertilizer requirements of crop growth, making it difficult to achieve efficient matching and synergy between the two, and unable to provide the best water and fertilizer supply conditions for crop growth, which seriously limits the improvement of agricultural production efficiency and the process of sustainable development.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0035] Reference Figure 1-Figure 7 As shown, the following are preferred embodiments provided by the present invention.

[0036] Example 1: Figure 1-Figure 5As shown, the scheme of this embodiment 1 provides a water-saving irrigation and fertilization device for agricultural planting, the structural design of the device includes a frame 1, a lifting mechanism 2 is installed on the frame 1, a fertilizer delivery component 3 is installed at the bottom of the lifting mechanism 2, a fertilizer box 4 is installed on one side of the lifting mechanism 2, a fertilizer discharge component 6 is installed at the bottom of the fertilizer box 4, a plurality of feed pipes 5 connected to the inside of the fertilizer box 4 are arranged at the bottom of the fertilizer box 4, a water tank 7 is installed on one side of the fertilizer box 4, a water pump 8 is connected to one side of the water tank 7, a base frame 9 is installed at the bottom of the frame 1 at the bottom of the water tank 7, a water spraying mechanism 10 is installed on the base frame 9, one end of the water spraying mechanism 10 is connected to a sealing component 11, and one end of the sealing component 11 is connected to the water delivery end of the water pump 8 through a pipeline.

[0037] In specific implementation, it is connected to the traction equipment through the frame 1. When irrigation and fertilization are carried out, first, the fertilizer delivery component 3 adjusts the spacing between each fertilizer pipe 308 according to the width of the gully to be fertilized, and then operates through the lifting mechanism 2 to make the bottom end of the fertilizer delivery component 3 inserted into the soil after rotary tillage. Then, the fertilizer discharge component 6 operates to discharge the fertilizer in the fertilizer box 4 from the feed pipe 5, enters the fertilizer pipe 308, and falls into the soil. At the same time, the water pump 8 operates to pump the water in the water tank 7 into the water spraying mechanism 10, and sprays it from each nozzle 1003. The third motor 1001 in the water spraying mechanism 10 operates, so that each nozzle 1003 can swing during the water spraying process, thereby increasing the water spraying range and the uniformity of the water spraying, ensuring that the fertilizer in the soil can contact with the water immersed in the soil, so that the fertilizer melts in the soil, thereby ensuring the effectiveness of the fertilizer, avoiding volatilization due to light, and improving the fertilization effect.

[0038] Among them, the lifting mechanism 2 includes multiple component structures such as a hydraulic pump 201, a hydraulic rod 202, a fixed frame 203, a first guide rod 204 and a side plate 205. The hydraulic pump 201 is directly fixed on the frame 1 by bolts, and the hydraulic pump 201 is connected to the hydraulic rod 202 through a pipeline. A group of fixed frames 203 are installed at the bottom of the hydraulic rod 202, and the first guide rod 204 slidably connected to the frame 1 is symmetrically installed on the top of the fixed frame 203. A group of side plates 205 are respectively installed at both ends of the bottom of the fixed frame 203, and fertilizer delivery components 3 are installed on the two side plates 205. The lifting mechanism 2 is used to cooperate with the fertilizer delivery component 3 to operate, so that the fertilizer delivery operation is more coordinated and more widely adapted to the fertilization needs of different soil depths.

[0039] During specific implementation, the hydraulic pump 201 is operated to make the hydraulic rod 202 extend and retract, and under the guidance of the two first guide rods 204, the fixed frame 203 can be stably raised and lowered, so that the height of the fertilizer delivery component 3 can be adjusted, so that the height of the fertilizer delivery component 3 can be adjusted according to the fertilization depth. At the same time, when the device is moved, the fertilizer delivery component 3 is at an appropriate height to avoid collision during movement.

[0040] The fertilizer delivery component 3 includes a first motor 301, a first screw rod 302, a second screw rod 303, a sliding bar 304, a slider 305, a connecting block 306, a connecting terminal 307 and a fertilizer pipe 308. The first motor 301 is fixedly mounted on the corresponding side plate 205 by fastening bolts. The number of the first screw rod 302 and the second screw rod 303 is multiple and staggered. Each of the first screw rod 302 and the second screw rod 303 is installed with a slider 305 slidably connected to the sliding bar 304, wherein a first screw rod 302 at the end is connected to the output end of the first motor 301, and each slider 305 is installed with a connecting block 306, a connecting terminal 307 is installed on one side of the connecting block 306, and a fertilizer pipe 308 is connected to the bottom end of the connecting terminal 307. The hydraulic pump 201 in the lifting mechanism 2 controls the extension and retraction of the hydraulic rod 202 to accurately adjust the height of the fertilizer delivery component 3 to adapt to the fertilization depth.

[0041] During specific implementation, after the device is powered, the first motor 301 is operated to cause the first screw 302 and the second screw 303 to rotate synchronously. Since the directions of the threads on the first screw 302 and the second screw 303 are oppositely distributed, the sliders 305 are moved closer to or away from each other along the slide rod 304, so that the distance between the fertilizer tubes 308 can be adjusted synchronously, thereby achieving the adjustment of the fertilizer spacing.

[0042] The connection ends 307 are respectively matched with the corresponding feed pipes 5 , and a corrugated hose is connected between each connection end 307 and the feed pipe 5 .

[0043] Among them, the fertilizer discharge component 6 includes a second motor 601, a rotating rod 602, a discharge roller 603 and a material receiving trough 604. The second motor 601 is installed at the bottom end of the outer side of the fertilizer box 4, wherein a group of rotating rods 602 for rotation are connected to the output end of the second motor 601, and a discharge roller 603 for discharging is coaxially fixed on the rotating rod 602. A plurality of material receiving troughs 604 are evenly arranged on the discharge roller 603, and the material can pass through the discharge roller 603 and spray out from the positions of the plurality of material receiving troughs 604. Among them, a sound insulation cover for noise reduction is arranged on the outside of the second motor 601, and sound insulation cotton and sound insulation felt are arranged inside the sound insulation cover, so as to effectively reduce the noise of the second motor 601 during movement.

[0044] During specific implementation, the second motor 601 is operated to make the rotating rod 602 drive the discharge roller 603 to rotate, so that each receiving trough 604 takes the fertilizer in the fertilizer box 4 in turn, aligns it with the discharge pipe 5 by rotation, and discharges it from the discharge pipe 5, so that the fertilizer can be discharged intermittently, avoiding continuous discharge of fertilizer, causing waste, and thus avoiding the situation of excessive fertilizer effect.

[0045] The water spraying mechanism 10 includes a third motor 1001, a water pipe 1002 and a nozzle 1003. The third motor 1001 is installed on the base frame 9. The output end of the third motor 1001 is connected to the water pipe 1002. A plurality of nozzles 1003 are evenly installed at the bottom end of the water pipe 1002. The operation of the third motor 1001 drives the water pipe 1002 to rotate, thereby realizing the swing of each nozzle 1003 to expand the water spraying range.

[0046] In specific implementation, the third motor 1001 is operated to make the water pipe 1002 rotate back and forth, so that the nozzles 1003 at the bottom swing back and forth, thereby increasing the water spraying range and uniformity, thereby avoiding water waste and improving water-saving effects.

[0047] The sealing assembly 11 includes a shaft seal 1101 and a fixed pipe 1102. The shaft seal 1101 is rotatably installed at one end of the water pipe 1002. The fixed pipe 1102 is coaxially installed in the shaft seal 1101. The fixed pipe 1102 is connected to the water delivery end of the water pump 8 with a water pipe. The shaft seal 1101 and the water pipe 1002 and the fixed pipe 1102 are all rotatably connected to achieve sealing of the water pipe 1002. When the water pipe 1002 rotates, the fixed pipe 1102 can be prevented from rotating, thereby preventing the water pipe from twisting and ensuring stable water delivery through the water pipe.

[0048] During specific implementation, the water in the water tank 7 is transported to the fixed pipe 1102 through the operation of the water pump 8, and then enters the water delivery pipe 1002. During the rotation of the water delivery pipe 1002, the water delivery pipe is prevented from twisting under the connection of the shaft seal 1101, thereby ensuring the stability of water delivery.

[0049] Embodiment 2:

[0050] like Figure 1 , Figure 6 and Figure 7 As shown, the scheme of this embodiment 2 provides a water-saving irrigation and fertilization device for agricultural planting, which differs from the embodiment 1 in that: a first electrode sheet 14 and an elastic electrode sheet 15 for controlling the operation of the water pump 8 are installed on one side of the bottom end of the fertilizer box 4, the first electrode sheet 14 is arranged above the elastic electrode sheet 15, and a fixed block 16 is arranged below the elastic electrode sheet 15, and three guide holes are opened on the fixed block 16. The first electrode sheet 14 and the elastic electrode sheet 15 form a control switch of the water pump 8. When the elastic electrode sheet 15 is under pressure and connected to the first electrode sheet 14, the water pump 8 can be operated, and when the elastic electrode sheet 15 is not under pressure, the elastic electrode sheet 15 automatically performs elastic recovery and separates from the first electrode sheet 14 to form a circuit break, so that the water pump 8 stops running.

[0051] An opening and closing control mechanism 12 is installed on the fixed block 16. The opening and closing control mechanism 12 is slidably matched with the three guide holes. The bottom end of the opening and closing control mechanism 12 is matched with a cam 13 installed at the end of the rotating rod 602. The guide holes are used to slide the connection with the opening and closing control mechanism 12, so that when the bottom of the opening and closing control mechanism 12 is subjected to pressure, it can automatically move upward, thereby squeezing the elastic pole piece 15. When the pressure on the bottom of the opening and closing control mechanism 12 disappears, the potential energy of the internal spring 1203 is released, so that the opening and closing control mechanism 12 automatically descends and slides to reset.

[0052] Among them, the opening and closing control mechanism 12 includes multiple components such as a push rod 1201, a push head 1202, a spring 1203, a force ring 1204 and a second guide rod 1205. The push rod 1201 is directly inserted into the guide hole in the middle. A group of push heads 1202 are installed on the top of the push rod 1201. The spring 1203 is sleeved on the push rod 1201. A force ring 1204 is installed at the bottom of the push rod 1201. The top of the force ring 1204 is symmetrically installed with a second guide rod 1205 that slides with the other two guide holes.

[0053] During specific implementation, the second motor 601 is operated, and the cam 13 is rotated during intermittent discharging. When the cam 13 squeezes the force ring 1204, the push rod 1201 rises, and the push head 1202 squeezes the elastic pole piece 15, so that the elastic pole piece 15 is connected to the first electrode piece 14, so that the water pump 8 is powered on and operated. When the connection between the cam 13 and the force ring 1204 is disconnected, the elastic pole piece 15 rebounds and the spring 1203 is reset, so that the water pump 8 stops running, so that intermittent water spraying is achieved during water spraying, and continuous water spraying causes the water spraying range to be covered, thereby ensuring the uniformity of water spraying, reducing the amount of water used for irrigation, and improving the irrigation water-saving effect in the agricultural planting process.

[0054] Working principle:

[0055] When the present invention is used for irrigation and fertilization, it is connected to the traction equipment through the frame 1. First, the fertilizer conveying component 3 adjusts the spacing between the fertilizer pipes 308 according to the width of the gully for fertilization, and then operates through the lifting mechanism 2 to make the bottom end of the fertilizer conveying component 3 inserted into the soil after rotary tillage. Then, the fertilizer discharge component 6 operates to discharge the fertilizer in the fertilizer box 4 from the feed pipe 5, enters the fertilizer pipe 308, and falls into the soil. At the same time, the second motor 601 operates, and the cam 13 rotates during the intermittent discharge process. When the cam 13 squeezes the force ring 1204, the push rod 1201 rises, and the push head 1202 squeezes the elastic pole piece 15, so that the elastic pole piece 15 is connected to the first electrode piece 14, so that the water pump 8 is powered on and operates. When the connection between 04 is disconnected, the elastic pole piece 15 rebounds and the spring 1203 is reset, so that the water pump 8 stops running, so that intermittent water spraying is achieved during water spraying, and continuous water spraying causes the water spraying range to be covered, thereby ensuring the uniformity of water spraying, reducing the amount of water used for irrigation, and improving the irrigation water-saving effect in the agricultural planting process. The water in the water tank 7 is intermittently pumped to the water spraying mechanism 10, and sprayed from each nozzle 1003. The third motor 1001 in the water spraying mechanism 10 is operated, so that each nozzle 1003 can swing during the water spraying process, thereby improving the water spraying range and uniformity, ensuring that the fertilizer in the soil can contact with the water immersed in the soil, so that the fertilizer melts in the soil, thereby ensuring the effectiveness of the fertilizer, avoiding volatilization due to light, and improving the fertilization effect.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
