Description

Technical Field

[0001] This invention relates to the field of irrigation equipment technology, specifically to a water-saving, integrated water and fertilizer irrigation device for corn. Background Technology

[0002] With the development of modern agriculture towards large-scale and intensive operations, the requirements for water and fertilizer utilization efficiency in corn planting are continuously increasing. Water-saving integrated water and fertilizer irrigation technology can achieve simultaneous water and fertilizer supply, improve corn yield and water resource utilization rate, and is increasingly widely used in field planting. Therefore, efficient and stable water-saving integrated water and fertilizer irrigation devices for corn are needed for precise irrigation operations.

[0003] However, existing irrigation devices often use a one-time feeding method to add fertilizer, which can easily lead to insufficient dissolution and clumping after the fertilizer is added in a concentrated manner. This makes it difficult for the fertilizer to mix thoroughly with the water, which not only reduces the quality of water-fertilizer mixing but also wastes fertilizer and results in low water-fertilizer utilization. Summary of the Invention

[0004] The purpose of this invention is to provide a water-saving fertigation device for corn. By setting up a feeding section, it solves the problem that existing irrigation devices often add fertilizer in a one-time feeding manner, which easily leads to insufficient dissolution and clumping of fertilizer after concentrated feeding. This makes it difficult for fertilizer to mix fully with water, which not only reduces the quality of water-fertilizer mixing but also wastes fertilizer and results in low water-fertilizer utilization.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a water-saving, integrated water and fertilizer irrigation device for corn, comprising a trolley and a mixing cylinder fixedly connected to the top of the trolley, and further comprising: an irrigation section mounted on the trolley; a feeding section mounted on the mixing cylinder; a mixing section disposed within the mixing cylinder; a flushing section disposed within the mixing cylinder; the feeding section comprising a feeding assembly mounted on the mixing cylinder; and a power assembly disposed within the mixing cylinder; the feeding assembly comprising a plurality of feeding boxes fixedly connected to the inner wall of the mixing cylinder, each feeding box having a plurality of feeding ports on its bottom inner wall, each feeding box having a sliding groove, and each sliding groove having a rectangular limiting plate slidably connected thereto, the rectangular limiting plates being... Each of the several feeding plates is fixedly connected to one of the adjacent sides. The adjacent sides of the feeding plates extend to the outside of several feeding boxes. The feeding plates are slidably connected to the feeding boxes. Each feeding plate has several feeding ports II. Elastic elements are provided in several sliding grooves. There are four feeding boxes arranged in a circular array. The several feeding ports II on each feeding plate are adapted to the several feeding ports I in the corresponding feeding box. The elastic elements include spring damping rods respectively provided in several sliding grooves. The adjacent sides of the several spring damping rods are fixedly connected to several rectangular limiting plates. The distant sides of the several spring damping rods are fixedly connected to the inner walls of the distant sides of the several sliding grooves.

[0007] Furthermore, the irrigation unit includes a water pump fixedly connected to the top of the cart, the water inlet of the water pump is connected to the mixing cylinder, the water outlet of the water pump is connected to a solenoid valve, and the right side of the solenoid valve is connected to an irrigation pipe.

[0008] Furthermore, the mixing section includes a transmission assembly disposed inside the mixing cylinder; and a mixing assembly disposed on the transmission assembly.

[0009] Furthermore, the flushing section includes a flushing assembly disposed inside the mixing cylinder; and an extrusion assembly disposed on the flushing assembly.

[0010] Furthermore, the power assembly includes a support plate fixedly connected between several feeding boxes. A motor is fixedly connected to the top of the support plate. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The bottom of the rotating shaft passes through the support plate and extends outward. The rotating shaft is rotatably connected to the support plate. An extrusion protrusion is fixedly connected to the outer wall of the rotating shaft. The extrusion protrusion is adapted to several feeding plates.

[0011] Furthermore, the transmission assembly includes two circular plates disposed at the bottom of the rotating shaft. The top of the upper circular plate is fixedly connected to the bottom of the rotating shaft. A plurality of guide rods are fixedly connected between the two circular plates. A circular cylinder is fixedly connected to the bottom inner wall of the mixing cylinder. A support rod is fixedly connected to the bottom inner wall of the circular cylinder. The top of the support rod passes through the lower circular plate. The support rod is rotatably connected to the lower circular plate. Two rectangular shells are slidably connected to the outer walls of the plurality of guide rods. An inclined transmission block is disposed within each of the two rectangular shells. Both inclined transmission blocks are fixedly connected to the support rod. A transmission block is disposed within each of the two inclined transmission blocks. The front side of each transmission block is fixedly connected to the rectangular shell. The top of the support rod is rotatably connected to the bottom of the upper circular plate. The support rod passes through the two rectangular shells, and the two rectangular shells are in contact with the support rod.

[0012] Furthermore, the mixing assembly includes several stirring shafts fixedly connected to the outer walls of two rectangular shells, and several C-shaped stirring paddles fixedly connected to the outer walls of the stirring shafts; each rectangular shell is provided with four stirring shafts arranged in a circumferential array, and each stirring shaft is provided with four C-shaped stirring paddles.

[0013] Furthermore, the flushing assembly includes several flushing holes formed on the outer wall of the cylindrical tube, an extrusion plate is slidably connected to the outer wall of the support rod, a spring is sleeved on the outer wall of the support rod, the top of the spring is fixedly connected to the extrusion plate, and the bottom of the spring is fixedly connected to the bottom inner wall of the cylindrical tube; the extrusion plate is located inside the cylindrical tube and in contact with it, and the spring is located below the extrusion plate.

[0014] Furthermore, the extrusion assembly includes a triangular protruding ring fixedly connected to the top of the extrusion plate, and an extrusion ring fixedly connected to the bottom of the circular plate below, the extrusion ring being adapted to the triangular protruding ring; both the triangular protruding ring and the extrusion ring are sleeved on the support rod.

[0015] Furthermore, the solenoid valve used in this device is a 2W-025-08 solenoid valve. Its working principle is to rely on the electromagnetic attraction generated after being energized to drive the valve core to move, thereby changing the on / off state of the channel inside the valve. When the power is off, the channel is closed again by relying on the internal spring to reset, thereby realizing the automatic control of the flow of water and fertilizer liquid.

[0016] The present invention has the following beneficial effects:

[0017] (1) By setting up a feeding section, water-soluble fertilizer and water are first added to the feeding box and mixing cylinder respectively during use. The motor drives the extrusion protrusion to rotate. Through the combination of extrusion and reset, the feeding plate moves back and forth, so that the upper and lower feeding ports periodically overlap and stagger, realizing the intermittent and multiple addition of fertilizer to the mixing cylinder. This avoids the fertilizer being added in one go, which leads to insufficient dissolution and clumping. It makes the fertilizer and water mix more thoroughly and evenly, improves the quality of water-fertilizer mixing, reduces fertilizer waste, and improves water-fertilizer utilization.

[0018] (2) By setting up a mixing section, when the rotating shaft rotates, the circular plate and guide rod drive the rectangular shell to make a circular motion around the support rod. Then, the stirring shaft drives the C-shaped stirring paddle to stir the water and fertilizer in the mixing cylinder. At the same time, under the cooperation of the inclined transmission block, the transmission block makes the rectangular shell drive the stirring paddle to move up and down synchronously, realizing compound motion stirring. This allows the stirring paddle to rotate in a circle and move up and down simultaneously, greatly expanding the stirring coverage area, making the fertilizer and water mix more fully and evenly, effectively preventing fertilizer from settling and clumping, and further improving the quality of water and fertilizer mixing.

[0019] (3) By setting up a flushing part, the lower circular plate rotates and drives the extrusion ring to rotate. The extrusion ring continuously squeezes the triangular protrusion ring through the inclined surface, causing the extrusion plate to slide up and down along the support rod. This causes the liquid in the circular cylinder to be repeatedly squeezed out and sucked in through the flushing hole, thereby achieving a circulating flushing of the bottom of the mixing cylinder. This continuous flushing of the bottom of the mixing cylinder effectively prevents water-soluble fertilizer from settling and clumping, ensuring that the bottom material can also fully participate in the mixing, and further improving the uniformity of water-fertilizer mixing.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The mixing unit 3 includes a transmission assembly 31 disposed inside the mixing cylinder 112; and a mixing assembly 32 disposed on the transmission assembly 31. The transmission assembly 31 includes two circular plates 311 disposed at the bottom of the rotating shaft 223. The top of the upper circular plate 311 is fixedly connected to the bottom of the rotating shaft 223. Several guide rods 312 are fixedly connected between the two circular plates 311. A circular cylinder 313 is fixedly connected to the bottom inner wall of the mixing cylinder 112. A support rod 314 is fixedly connected to the bottom inner wall of the circular cylinder 313.

The top of the support rod 314 is rotatably connected to the bottom of the circular plate 311 located above. The support rod 314 passes through the two rectangular shells 315, and the two rectangular shells 315 are in contact with the support rod 314. The mixing component 32 includes several stirring shafts 321 that are fixedly connected to the outer walls of the two rectangular shells 315 respectively. Several C-shaped stirring paddles 322 are fixedly connected to the outer walls of the stirring shafts 321. Each rectangular shell 315 is provided with four stirring shafts 321 arranged in a circumferential array. Each stirring shaft 321 is provided with four C-shaped stirring paddles 322. By setting the mixing part 3, the stirring paddles can simultaneously rotate in a circle and move up and down, greatly expanding the mixing coverage area, making the fertilizer and water mix more thoroughly and evenly, effectively preventing fertilizer sedimentation and clumping, and further improving the quality of water and fertilizer mixing.

[0036] The flushing section 4 includes a flushing assembly 41 disposed inside the mixing cylinder 112; and an extrusion assembly 42 disposed on the flushing assembly 41. The flushing assembly 41 includes a plurality of flushing holes 411 formed on the outer wall of the cylindrical cylinder 313. An extrusion plate 412 is slidably connected to the outer wall of the support rod 314. A spring 413 is sleeved on the outer wall of the support rod 314. The top of the spring 413 is fixedly connected to the extrusion plate 412, and the bottom of the spring 413 is fixedly connected to the bottom inner wall of the cylindrical cylinder 313. The extrusion plate 412 is located inside the cylindrical cylinder 313. In contact, spring 413 is located below extrusion plate 412. Extrusion assembly 42 includes a triangular protruding ring 421 fixedly connected to the top of extrusion plate 412. Extrusion ring 422 is fixedly connected to the bottom of circular plate 311 located below. Extrusion ring 422 is adapted to triangular protruding ring 421. Both triangular protruding ring 421 and extrusion ring 422 are sleeved on support rod 314. By setting flushing part 4, the bottom of mixing cylinder 112 is continuously flushed, which effectively avoids water-soluble fertilizer from settling and clumping, and ensures that the bottom material can also fully participate in mixing, further improving the uniformity of water and fertilizer mixing.

[0037] It should be noted that the water pump 113, solenoid valve 114 and motor 222 in this application can all be automatically controlled by using a program set in the control panel and inputting relevant parameters as needed. This control method can be achieved using existing technologies, such as PLC.

[0038] In use, water-soluble fertilizer is added to the four feeding boxes 211, followed by water to the mixing cylinder 112. Then, the motor 222 is started, which drives the extrusion protrusion 224 to rotate via the rotating shaft 223. At this time, the extrusion protrusion 224 extrudes the feeding plate 215, causing the feeding plate 215 to push the rectangular limiting plate 214 into the slide groove 213. The rectangular limiting plate 214 extrudes the spring damping rod 217, causing the spring damping rod 217 to deform and generate elastic force. At this time, the feeding plate 215 drives several feeding ports 216 to the feeding boxes. Several discharge ports 212 on 211 overlap. At this time, water-soluble fertilizer falls into the mixing cylinder 112 through several overlapping discharge ports 216 and several discharge ports 212. When the extrusion protrusion 224 passes through the discharge plate 215, the extrusion force on the spring damping rod 217 disappears and the elastic force is released. The elastic force acts on the rectangular limiting plate 214. The rectangular limiting plate 214 pushes the discharge plate 215 to reset, so that several discharge ports 216 and several discharge ports 212 are staggered again, so that water-soluble fertilizer is added into the mixing cylinder 112 in sequence and repeatedly.

[0039] During the rotation of the rotating shaft 223, the rotating shaft 223 drives the four guide rods 312 to rotate through the corresponding circular plate 311. The guide rods 312 drive the circular plate 311 located below to rotate on the support rod 314. At this time, the four guide rods 312 drive the two rectangular shells 315 to perform circular motion on the support rod 314. The rectangular shells 315 drive the C-shaped stirring paddle 322 to perform circular motion in the mixing cylinder 112 through the stirring shaft 321, thereby stirring the water and water-soluble fertilizer in the mixing cylinder 112. During this process, the rectangular shells 315 drive the transmission block 317 to move in the inclined transmission block 316. Under the action of the inclined transmission block 316, the rectangular shells 315 are prompted to move up and down on the support rod 314, which is coordinated with the circular motion, thereby increasing the stirring range.

[0040] During the rotation of the lower circular plate 311, the circular plate 311 drives the extrusion ring 422 to rotate and is extruded by the inclined surface of the triangular convex ring 421, causing the triangular convex ring 421 to move downward. The triangular convex ring 421 pushes the extrusion plate 412 to slide downward on the support rod 314, thereby quickly extruding the contents of the circular cylinder 313 through the four flushing holes 411, thus flushing the bottom of the mixing cylinder 112. During this process, the spring 413 is compressed by the extrusion plate 412, deforms and generates elastic force. When the extrusion ring 422 passes the triangular convex ring 421, the extrusion force on the spring 413 disappears, releasing the elastic force. The elastic force acts on the extrusion plate 412, causing the extrusion plate 412 to return to its original position. At this time, the extrusion plate 412 draws water back into the circular cylinder 313 through the four flushing holes 411, thereby repeatedly flushing the bottom of the mixing cylinder 112 to prevent the deposition of water-soluble fertilizer.

[0041] By activating the solenoid valve 114 and the water pump 113, the water pump 113 draws out the dissolved water and water-soluble fertilizer from the mixing cylinder 112 and injects them into the irrigation pipe 115 through the solenoid valve 114, thereby irrigating the corn.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
