Description

Technical Field

[0001] The present invention relates to the technical field of agricultural equipment, and particularly relates to a precise fertilization device for ecological environment protection. Background Art

[0002] With the development of agricultural technology, precise fertilization technology plays an important role in improving crop yield and quality, saving resources and protecting the environment. The precise fertilization device ensures that crops receive appropriate nutrient supply by controlling the amount and application position of fertilizers, while reducing fertilizer waste and environmental pollution.

[0003] Existing precise fertilization devices are mostly fixed, relying on pipeline systems for fertilizer transportation and distribution. Although such devices can achieve drip irrigation or sprinkler fertilization at fixed positions of plants, there are some obvious deficiencies. Firstly, laying pipelines in the early stage requires a large amount of materials and labor, resulting in high costs. Secondly, due to the long pipelines, maintenance and detection work are cumbersome, increasing the difficulty of daily management. In addition, after the fertilizer is dissolved in water, even with a filtering device, there will still be residual fertilizer in the pipeline that has not been discharged after fertilization. Long-term accumulation is likely to cause precipitation and block the pipeline, affecting the uniformity of fertilization. The fertilizer concentration is too high at the precipitation site, while too low at other sites, which will lead to uneven growth of crops. Summary of the Invention

[0004] In order to overcome the above technical problems, the purpose of the present invention is to provide a precise fertilization device for ecological environment protection.

Two first ring frames 430 are provided and are respectively fixed to the outer walls of the second water pipe 413 and the third water pipe 421. A fourth spring 431 is fixed to the outer wall of the first ring frame 430. The other end of the fourth spring 431 is fixedly connected to a second ring frame 432.

Two spring telescopic rods 436 are provided and are respectively rotated on the outer walls of two of the sliding frames 433. A pull ring 437 is fixed to one end of the spring telescopic rod 436.

[0080] Specifically, during operation, the vehicle body 110 drives to drive the precise fertilization mechanism 100 to move to a designated position. According to the position of the plants, the position of the circular frame 220 is adjusted. When it is necessary to adjust the position of a certain circular frame 220, the first motor 230 drives to drive the spur gear 231 to mesh with the rack 212, so that the arc-shaped frame 235 moves to the corresponding position of the circular frame 220. The second electric telescopic rod 340 drives to drive the first slide rail 210 to move upward until one end of the first L-shaped frame 112 contacts one end of the inclined rod 234. One end of the inclined rod 234 is squeezed to drive the arc-shaped frame 235 to slide towards the circular frame 220. The arc-shaped frame 235 squeezes one end of the U-shaped frame 223, so that the other end is separated from the first square hole 211. The first motor 230 drives to drive the circular frame 220 clamped by the arc-shaped frame 235 to be adjusted to the designated position. After the adjustment, the soil is detected to see if fertilization is needed. The second electric telescopic rod 340 drives to drive the first slide rail 210 to move downward until the soil NPK sensor 227 is inserted into the soil. Through the analysis of the soil NPK sensor 227, when it is analyzed that all the juxtaposed plants need fertilization, the second motor 330 drives to drive the square frame 332 to rotate and contact the surface of one end of the first square rod 310. The first square rod 310 is squeezed and slides towards one side of the circular frame 220 until the second round hole 314 corresponds to the first round hole 221. The mixture of fertilizer and water flows out from the storage tank 120, flows into the first water pipe 410 along the filter screen replacement mechanism 400, and then flows into the first round hole 221 from the first water pipe 410 and drips out from the nozzles at the bottom of the circular frame 220. When the soil NPK sensor 227 analyzes that only individual plants need fertilization, the first motor 230 drives to drive the square plate 321 to move to the corresponding position of the circular frame 220 above the plant to be fertilized. The first electric telescopic rod 322 drives to drive the second inclined block 323 to move downward until it contacts the first inclined block 311, so that the first inclined block 311 slides towards the second L-shaped frame 313 until the second round hole 314 corresponds to the second square hole 225, and then the material can be discharged. When it is necessary to replace the filter screen pipe 440, pull out the pull ring 437 and twist it to separate the third square rod 438 from a group of square blocks 435, release the limit between two adjacent sliding frames 433, and pull the handle 445 in the direction of the pull ring 437. The V-shaped frame 444 contacts the outer wall of the sliding frame 433, so that the sliding frame 433 slides to one side, separating the second ring frame 432 from the outer wall of the filter screen pipe 440, and then the filter screen pipe 440 can be taken out. When installing, install it from the other end of the sliding frame 433. The V-shaped frame 444 contacts the outer wall of one end of the sliding frame 433, so that the sliding frame 433 slides to one side, pulling the filter screen pipe 440 to the inside of the second ring frame 432. Due to the rebound of the fourth spring 431, the second ring frame 432 is inserted into the filter screen pipe 440, and a seal is provided inside the second ring frame 432 to prevent leakage. After installation, pull out the pull ring 437 and twist it to insert the third square rod 438 into a group of square blocks 435 to limit the two sliding frames 433.

[0083] In this embodiment, according to the position of the plant, the position of the circular frame 220 is adjusted.

The second electric telescopic rod 340 drives the first slide rail 210 to move upward until one end of the L-shaped frame 112 contacts one end of the inclined rod 234. One end of the inclined rod 234 is squeezed to drive the arc-shaped frame 235 to slide towards the circular frame 220. The arc-shaped frame 235 squeezes one end of the U-shaped frame 223, so that the other end is separated from the square hole 211. The first motor 230 drives the circular frame 220 clamped by the arc-shaped frame 235 to be adjusted to the designated position. By adjusting the position of the circular frame 220 according to the position of the vegetation for precise drip irrigation and measurement, it can ensure that water is directly delivered to the roots of the plants, reduce water evaporation and waste, improve irrigation efficiency.

The second electric telescopic rod 340 drives the first slide rail 210 to move downward until the soil NPK sensor 227 is inserted into the soil. Through analysis by the soil NPK sensor 227, when it is analyzed that all the juxtaposed plants need fertilization, the second motor 330 drives the square frame 332 to rotate and contact the surface of one end of the first square rod 310. The first square rod 310 is squeezed and slides towards the side of the circular frame 220 until it reaches the position corresponding to the first round hole 221 at 228. The mixture of fertilizer and water flows out from the storage tank 120, flows into the first water pipe 410 along the filter screen replacement mechanism 400, then flows into the first round hole 221 from the first water pipe 410, and drips out from the nozzles at the bottom of the circular frame 220. When the soil NPK sensor 227 analyzes that only individual plants need fertilization, the first motor 230 drives the square plate 321 to move to the position of the circular frame 220 corresponding to the plant that needs fertilization above. The first electric telescopic rod 322 drives the second inclined block 323 to move downward until it contacts the first inclined block 311, causing the first inclined block 311 to slide towards the second L-shaped frame 313 until 228 corresponds to the second square hole 225, and then the material can be discharged. Through the precise feeding mechanism 300, the soil can be detected. Based on the detection results, unified fertilization or individual fertilization can be carried out, avoiding the waste of fertilizer. At the same time, it avoids excessive fertilizer in local soil, resulting in salt accumulation in the soil, causing soil salinization and affecting the normal growth of crops, effectively improving the accuracy of drip irrigation.

[0086] Embodiment 2

[0087] As Figures 8-9 shown, the filter screen replacement mechanism 400 includes the following parts: There are two first ring frames 430, which are respectively fixed on the outer walls of the second water pipe 413 and the third water pipe 421. The fourth spring 431 is fixed on the outer wall of the first ring frame 430, and the other end of the fourth spring 431 is fixedly connected with the second ring frame 432. The inner wall of the second ring frame 432 is slidably inserted with the outer wall of the filter screen pipe 440. There are two sliding frames 433, which are fixedly arranged on the outer wall of the second ring frame 432 at equal angles. And a semi-circular groove 434 is opened on one side outer wall of one end of the sliding frame 433. A group of squares 435 are arranged and fixed inside the semi-circular groove 434. There are two spring telescopic rods 436, which are respectively rotated on the outer walls of two of the sliding frames 433. A pull ring 437 is fixed at one end of the spring telescopic rod 436. There are two third square rods 438, which are fixedly arranged at equal intervals on the outer wall of the pull ring 437 at both sides. And the outer wall of the third square rod 438 is slidably inserted between a group of squares 435. The third ring frame 441 is clamped on the outer wall of the filter screen pipe 440. Two second slide rails 442 are fixedly connected to the outer wall of the third ring frame 441 at equal angles. And one end of the V-shaped frame 444 is slidably inserted into the second slide rail 442. A fifth spring 443 is fixedly connected between the outer wall of the V-shaped frame 444 and the inner wall of the second slide rail 442. A handle 445 is fixed on the outer wall of the V-shaped frame 444.

[0088] During specific implementation, when the filter screen tube 440 needs to be replaced, pull out the pull ring 437 and twist it to separate the third square rod 438 from a group of square blocks 435, releasing the limit between two adjacent sliding brackets 433. Pull the grip 445 in the direction of the pull ring 437. The V-shaped bracket 444 contacts the outer wall of the sliding bracket 433, causing the sliding bracket 433 to slide to one side, separating the second ring bracket 432 from the outer wall of the filter screen tube 440, and then the filter screen tube 440 can be taken out. During installation, install it from the other end of the sliding bracket 433. The V-shaped bracket 444 contacts the outer wall of one end of the sliding bracket 433, causing the sliding bracket 433 to slide to one side, pulling the filter screen tube 440 to the inside of the second ring bracket 432. Due to the rebound of the fourth spring 431, the second ring bracket 432 is inserted into the filter screen tube 440. Moreover, a seal is provided inside the second ring bracket 432 to prevent leakage. After installation, pull out the pull ring 437 and twist it to insert the third square rod 438 into a group of square blocks 435, limiting the two sliding brackets 433. Through the filter screen replacement mechanism 400, personnel can conveniently and quickly replace the filter screen tube 440 without the assistance of other tools and without much effort, effectively improving the replacement efficiency and convenience.
