Description

Technical Field

[0001] The invention relates to the field of deep soil loosening and deep application of water and fertilizer, and more specifically to a device for combining deep soil loosening and water and fertilizer driven by air pressure. Background Art

[0002] In agricultural production, deep soil loosening is an important measure to improve soil permeability and water storage capacity and promote the growth of plant roots. Traditional soil deep loosening methods often rely on mechanical plowing or rotary tillage. These methods can improve soil structure to a certain extent, but they have disadvantages such as high energy consumption, severe soil compaction below the plow bottom, great damage to soil structure, and low work efficiency.

[0003] In the existing technology, for example, in the document with the announcement number CN222090088U, a soil aeration device is specifically disclosed, in which the device lifts up the inner aeration tube through an electric telescopic rod, and the second aeration hole of the outer aeration tube coincides with the first aeration hole of the inner aeration tube to start aeration, thereby increasing the gap between soil particles, thereby achieving the purpose of loosening the soil. However, although this method has achieved certain effects in loosening the soil, in actual operation, the operator often needs to inject nutrients into the soil again after the soil is loosened.

[0004] However, this step-by-step operation method increases the complexity of the operation. The operator needs to perform soil loosening and nutrient supplementation steps separately, which is not only time-consuming and labor-intensive, but also reduces work efficiency, because each time the soil is loosened, it is necessary to wait for the nutrient agent to be injected again, which leads to the extension of the entire operation process. Therefore, a pneumatically driven soil deep loosening and water-fertilizer combined device is designed. Summary of the invention

[0024] In the prior art, deep loosening and liquid fertilizer are generally performed in steps, which increases the complexity of the operation. The operator needs to perform two steps, deep loosening the soil and adding liquid fertilizer, respectively. This is not only time-consuming and labor-intensive, but also reduces work efficiency, because after each loosening of the soil, it is necessary to wait for liquid fertilizer to be injected again, which prolongs the entire operation time and reduces work efficiency.

[0025] In order to solve the above problems, the present application provides an air pressure driven soil deep loosening and water-fertilizer combined device, which can use air pressure to deep loosen the soil and inject liquid fertilizer into the soil while loosening the soil, thereby simplifying the operation process and improving work efficiency. At the same time, the device should also be easy to operate, easy to maintain, and highly adaptable to meet the needs of different soil types and crop growth.

[0038] A second spring 312 is fixedly connected to the top of the inner wall of the insertion rod 302, and a plurality of first fixed beads 313 are fixedly connected to the circumferential outer wall of the second spring 312. A first steel wire rope 314 is fixedly connected between two adjacent first fixed beads 313.

[0039] The inner wall of the insertion rod 302 is slidably connected to the first piston 308, and the circumferential outer wall of the first piston 308 is fixedly connected to a plurality of second sealing rings 316, the second sealing ring 316 is slidably connected to the inner wall of the insertion rod 302, the bottom of the first piston 308 is fixedly connected to the third spring 317, the inner wall of the insertion rod 302 is fixedly connected to the tray 321, the bottom of the third spring 317 is fixedly connected to the tray 321, the circumferential outer wall of the third spring 317 is fixedly connected to a plurality of second fixing beads 318, a second steel wire rope 319 is fixedly connected between two adjacent second fixing beads 318, the inner wall of the insertion rod 302 is provided with a plurality of guide holes 320, and the second branch pipe 307 is located between the first piston 308 and the second piston 309.

[0040] When the first piston 308 reaches below the guide hole 320, the compressed air and liquid fertilizer in the insertion rod 302 are ejected through the guide hole 320 and the injection hole 322, impacting the soil and loosening it, while the liquid fertilizer diffuses in the soil. After the injection is completed, the hydraulic rod 106 drives the insertion rod 302 to be withdrawn, and the first piston 308 slides up to a position under the elastic force of the third spring 317, and the second piston 309 slides up to a limit position under the pulling force of the second spring 312.

[0041] In addition, this embodiment provides a gas pressure driven soil deep loosening and water and fertilizer combined device, which also includes the following structure on the basis of the third embodiment: The inner wall of the liquid guiding tube 206 is fixedly connected to a supporting filter plate 208, the outer wall of the supporting filter plate 208 is fixedly connected to a plurality of bristles 209, the outer wall of the supporting filter plate 208 is fixedly connected to a cam rod 212, the circumferential outer wall of the cam rod 212 is provided with a spiral groove 213, the inner wall of the spiral groove 213 is slidably connected to a protrusion 214, the circumferential outer wall of the cam rod 212 is slidably connected to a filter plate 210, the inner wall of the filter plate 210 is fixedly connected to the protrusion 214, and the outer wall of the filter plate 210 is provided with a plurality of arc holes 211.

[0042] An installation groove 215 is provided on the outer wall of the cam rod 212, and a slide rod 216 is fixedly connected to the inner wall of the installation groove 215. A first spring 217 is sleeved on the circumferential outer wall of the slide rod 216. A slider 218 is slidably connected to the circumferential outer wall of the slide rod 216. The end of the slider 218 extends to the outside of the cam rod 212, one end of the first spring 217 is fixedly connected to the inner wall of the cam rod 212, and the other end of the first spring 217 is fixedly connected to the slider 218.

[0043] The particles in the liquid fertilizer are filtered through the arc holes 211 on the filter disc 210, thereby ensuring the purity of the fertilizer. When the arc holes 211 are blocked, the filter disc 210 can automatically rotate under the action of water pressure and cooperate with the bristles 209 for cleaning, thereby avoiding the blockage problem caused by the accumulation of particles. During the cleaning process, the rotation of the filter disc 210 and the design of the arc holes 211 make it easier for the bristles 209 to be inserted into the arc holes 211, thereby improving the cleaning efficiency. When the filter disc 210 moves, the spring can be compressed and reset under the action of the spring elastic force, thereby facilitating the cleaning of particles in the liquid guide cylinder 206. When the arc hole 211 on the filter disc 210 is clogged, under the action of water pressure, the filter disc 210 drives the protrusion 214 to slide along the inner wall of the spiral groove 213 on the cam rod 212, so that the filter disc 210 rotates during the movement. The rotating filter disc 210 and the bristles 209 produce friction, so that the bristles 209 can be smoothly inserted into the arc hole 211 to clean the particles inside the arc hole 211. At the same time, the rotating filter disc 210 can make the bristles 209 move in the arc hole 211. This dynamic process ensures that there will be no continuous blockage points in the arc hole 211, and avoids the situation where the bristles 209 are blocked in the arc hole 211 due to replacing particles, resulting in the inability of the liquid to pass through the filter disc 210 smoothly. When the filter disc 210 moves, it can push the slider 218 to slide along the slide rod 216 and compress the first spring 217. After a single injection of liquid fertilizer, at this time, under the elastic force of the first spring 217, the slider 218 pushes the filter disc 210 in the opposite direction along the slide rod 216 to move, so that the filter disc 210 is out of contact with the bristles 209. By removing the cylinder cover, the particulate matter in the liquid guide cylinder 206 can be cleaned.

[0044] The device is not only suitable for the application of liquid fertilizer, but also can realize the combined use of irrigation water and biogas slurry.

[0045] Working principle: First, install the mounting frame 101 on the mobile vehicle, then connect the end of the second air pipe 202 to the pressurized air pipe equipped on the mobile vehicle to ensure smooth air pressure transmission; at the same time, connect the end of the third material pipe 207 to the liquid infusion pipe storing liquid fertilizer on the mobile vehicle to ensure the supply of liquid fertilizer; Subsequently, the liquid fertilizer delivery process is started, and the liquid fertilizer is quantitatively delivered to the third material pipe 207, and smoothly enters the liquid guide cylinder 206, and then enters the second material pipe 204, and flows into the first material pipe 203 after being regulated by the first one-way valve 205. Then, the liquid fertilizer is delivered to the inside of the insertion rod 302 through the first material pipe 203 and the second branch pipe 307, and is stored in the space between the first piston 308 and the second piston 309; The compressed air is transported to the first air pipe 201 through the second air pipe 202, and the compressed air is transported to the inside of the plug rod 302 through the first air pipe 201 and the first branch pipe 304. At this time, the second piston 309 slides downward along the inner wall of the plug rod 302 under the push of the compressed air, so that the second spring 312 is stretched. When the second piston 309 slides, the liquid fertilizer is compressed until the first steel wire rope 314 is fully stretched. The first piston 308 slides downward along the plug rod 302 and compresses the third spring 317. Under the elastic force of the third spring 317, the air inside the plug rod 302 is fully compressed; The connecting frame 107 is pushed downward by the hydraulic rod 106, and the second connecting plate 109 is driven to move through the first connecting plate 108. The second connecting plate 109 drives the insertion rod 302 to move downward through the connecting shaft 110. When the insertion rod 302 moves, it drives the first branch pipe 304 and the second branch pipe 307 to move downward along the extension hole 103 respectively. When the sealing sleeve 306 at the bottom of the conveying sleeve 301 contacts the ground, the connecting shaft 110 drives the insertion rod 302 to be inserted into the soil. When the first piston 308 slides to below the guide hole 320, the compressed air and the compressed liquid fertilizer in the plug rod 302 are sprayed out through the guide hole 320 and the injection hole 322 on the plug nozzle 310, and the compressed air impacts the soil, making the soil looser. At the same time, driven by the compressed air, the liquid fertilizer diffuses inside the soil. After injection, the hydraulic rod 106 drives the insertion rod 302 to be pulled out from the soil. At this time, under the elastic force of the compressed third spring 317, the first piston 308 slides upward along the insertion rod 302 until the second steel wire rope 319 is fully straightened, thereby positioning the position of the first piston 308. At the same time, under the pulling force of the second spring 312, the second piston 309 slides upward along the insertion rod 302 until it contacts the limiting ring 311, thereby limiting the position of the second piston 309.
