Description

Technical Field

[0001] This invention relates to the field of seedling planting technology, specifically to a high-efficiency fertilization device for afforestation seedlings. Background Technology

[0002] Afforestation refers to taking certain measures in areas where there is no vegetation or sparse vegetation, through artificial planting of trees or promoting the restoration of natural ecology, in order to increase vegetation coverage, protect the environment and increase ecological benefits. Greening and afforestation is one of the important measures for mankind to cope with climate change, protect the environment and maintain ecological balance. Among them, the placement of seedlings is an important link.

[0003] Seedlings are tree seedlings with roots and trunks. All seedlings cultivated in nurseries, regardless of age, are called seedlings before they leave the nursery. In the afforestation process, in order to promote the growth of seedlings, fertilizers and nutrient solutions are needed to deliver nutrients to them when the seedlings or seeds are planted in the soil. The soil needs to be turned over before fertilization.

[0004] Currently, soil loosening and fertilization are mainly carried out manually and mechanically. Manually loosening the soil and fertilizing is time-consuming, labor-intensive, and results in uneven fertilization. Mechanized methods of loosening soil and fertilizing require the use of different equipment in sequence, which has certain shortcomings in terms of work efficiency and fertilizer application effect. At the same time, the existing fertilization equipment has relatively limited functions, and the nutrient solution spraying range is not flexible enough. It often uses high-point spraying, which results in some loss of nutrient solution due to evaporation. In addition, the existing equipment cannot switch between liquid and solid fertilizers, thus limiting its operational capabilities.

[0005] Therefore, the present invention aims to provide an efficient fertilization device for afforestation seedlings, which improves upon existing technology through diversified functional design. Summary of the Invention

[0020] Preferably, the atomizer is connected to the interior of the storage tank via a connecting pipe.

[0021] Working principle: The seedling fertilization device provided by this invention mainly includes the following working steps in practical application:

[0022] Step 1: Preliminary preparation: Before the equipment starts working, it is necessary to add granular fertilizer and soil nutrient solution, and check all electrical and mechanical components of the equipment to ensure that there are no faults. To add solid granular fertilizer, simply open the top cover of the storage cylinder. To add soil nutrient solution, open the injection port on one side of the top of the storage tank. After completing the preliminary operation steps, you can proceed to the subsequent operation.

[0023] Step 2, Soil Loosening: In this step, when the vehicle moves to the corresponding position, the electric push rod is activated, causing it to move downwards. Under the push of the electric push rod, the push plate simultaneously presses against the connecting plate, causing the connecting plate to move downwards as well. This allows the bottom of the multi-column frame to emerge from the center of the annular cylinder, approaching the soil surface. At this point, the fifth motor installed at the top of the multi-column frame is activated, driving the screw fixedly connected to its output end to rotate. Under meshing action, the threaded block connected to the screw's outer wall moves. As the threaded block moves downwards, the four mounting brackets gradually unfold under the support of the struts. Then, by activating two of the sixth motors, the loosening cutter wheels can be driven to rotate, while the other two sixth motors... The cross shovels installed under the machine are stationary. When the four mounting frames are unfolded, the fourth motor is started, which drives the second pulley fixedly connected to its output end to rotate. The second pulley drives the first pulley to rotate, which in turn drives the rotating column to rotate, causing the entire multi-column frame to rotate. At this time, the electric push rod is started again, which makes the rotating multi-column frame press against the soil surface. With the cooperation of the loosening blade and the cross shovels, the soil is loosened. In actual work, the loosening range of the soil can be expanded or reduced by controlling the movement of the threaded block, while the loosening depth can be adjusted by controlling the extension length of the electric push rod, which improves the loosening flexibility and meets the loosening needs of actual afforestation sites.

[0024] Step 3: Near-ground spraying of soil nutrient solution: After loosening the soil, the spray head is activated to spray nutrient solution close to the soil surface. During the spraying process, the lower spraying distance reduces the evaporation loss of the liquid nutrient solution, improving the problem of large soil nutrient solution loss caused by the higher spraying position of traditional spraying devices. By activating the third motor, the first gear fixedly connected to its output end can be driven to rotate. Under the driving action of the first gear, the clamping ring will rotate, which will drive multiple ring-shaped second gears to rotate, causing the spray head to swing at a certain angle, improving the uniformity of spraying and increasing the spraying range, making it more flexible and controllable.

[0025] Step 4: Fertilization of the main body of the seedlings: After the seedlings are planted, fertilization of the main body of the seedlings can be carried out through the multi-angle atomizing spraying mechanism set at the front of the vehicle top. At this time, seedling nutrient solution needs to be added into the storage tank. In actual processing, by starting the atomizer, the seedling nutrient solution in the storage tank can be atomized and sprayed out through the nozzle. By starting the fan, the atomized seedling nutrient solution can be blown a longer distance. By starting the second motor, the tilt angle of the fan can be changed, making the spraying angle of the seedling nutrient solution flexible and variable. In conjunction with the first motor driving the first bevel gear to rotate, and the first bevel gear driving the second bevel gear to rotate, the main spraying direction of the atomizer can be adjusted. Compared with traditional seedling fertilization devices, it can evenly spray all parts of the seedling body, improving the spraying efficiency of the seedling nutrient solution.

[0026] Step 5: Solid fertilizer application: When solid fertilizer needs to be applied, the fixed box installed on one side of the fixed box is started, which drives the connecting rod fixedly connected to its output end to rotate. The worm gears set at equal intervals on the connecting rod drive the worm wheel meshing with it to rotate, and drive the auger blade fixedly connected to the top of the worm wheel to rotate. When the auger blade rotates, the solid soil fertilizer that enters the application cylinder from the storage cylinder through the conveying pipe will be continuously conveyed upward until it is applied from the discharge port and falls into the loosened soil. This completes the application of solid granular fertilizer. By controlling the rotation of the seventh motor, the amount of solid granular fertilizer applied at the same location can be controlled, realizing the precise quantitative application of solid fertilizer.

[0027] The high-efficiency fertilization device for afforestation seedlings provided by this invention can realize the integrated operation of loosening soil and fertilizing soil in afforestation sites. It integrates both solid and liquid fertilizers and can also add nutrient solution to seedlings after planting. It has high operation efficiency, good functionality, and good application effect in afforestation and tree planting operations.

[0028] This invention provides a high-efficiency fertilization device for afforestation seedlings. It has the following beneficial effects:

[0029] 1. This invention, by setting up a near-ground spraying mechanism, after the soil loosening operation is completed, can spray nutrient solution by activating the spray head at a position close to the soil surface. During the spraying process, the lower spraying distance reduces the evaporation loss of the liquid nutrient solution, improving the problem of large soil nutrient solution loss caused by the higher spraying position in traditional spraying devices. By activating the third motor, the first gear fixedly connected to its output end can be driven to rotate. Under the driving action of the first gear, the clamping ring will rotate, which will drive multiple ring-shaped second gears to rotate, causing the spray head to swing at a certain angle, improving the spraying uniformity of the device, increasing the spraying range, and making it more flexible and controllable.

[0030] 2. This invention, by setting up an adjustable soil loosening mechanism, presses the rotating multi-column frame against the soil surface and loosens the soil with the cooperation of the loosening blade wheel and the cross shovel. The loosening range can be expanded or reduced by controlling the movement of the threaded block, and the loosening depth can be adjusted by controlling the extension length of the electric push rod, which improves the flexibility of soil loosening and meets the soil loosening needs of actual afforestation sites.

[0031] 3. This invention, by setting up a granular fertilizer dispensing mechanism, allows for the dispensing of solid fertilizer when the fixed box installed on one side of the fixed box is activated. This activates the fixed box, which drives the connecting rod fixedly connected to its output end to rotate. The worm gears, which are equidistantly arranged on the connecting rod, drive the worm wheel meshing with it to rotate, and in turn drive the auger blade fixedly connected to the top of the worm wheel to rotate. When the auger blade rotates, the solid soil fertilizer that enters the dispensing cylinder from the storage cylinder through the conveying pipe is continuously conveyed upwards until it is dispensed from the outlet and falls into the loosened soil, thus completing the dispensing of solid granular fertilizer. By controlling the rotation of the seventh motor, the amount of solid granular fertilizer dispensed at the same location can be controlled, achieving precise quantitative application of solid fertilizer.

[0032] 4. This invention, through the coordinated operation of multiple functional mechanisms, can achieve integrated soil loosening and fertilization in afforestation sites. It integrates both solid and liquid fertilizers, and can also administer nutrient solution to seedlings after planting. The spraying angle of the nutrient solution is flexible and variable. Compared with traditional seedling fertilization devices, it can evenly spray all parts of the seedling body, improving the spraying efficiency of the nutrient solution. The device has high overall functionality and good application effect in afforestation and tree planting operations. Attached Figure Description

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example:

[0050] Please see the appendix Figure 1 -Appendix Figure 14 This invention provides a high-efficiency fertilization device for afforestation seedlings, comprising a vehicle body 1, a multi-angle atomizing spraying mechanism 2 for atomizing and spraying soil nutrient solution at the front top of the vehicle body 1; a near-ground spraying mechanism 3, which is located at the middle top of the vehicle body 1 for storing and spraying soil nutrient solution; an adjustable soil loosening mechanism 4, which is located at the middle of the near-ground spraying mechanism 3 for loosening the soil to be fertilized; and a granular fertilizer dispensing mechanism 5, which is located at the rear top of the vehicle body 1 for quantitative dispensing of solid granular fertilizer.

[0051] For further details, please refer to the appendix. Figure 4 -Appendix Figure 5The multi-angle atomizing spraying mechanism 2 includes a fixed cover 201, which is fixedly connected to the front top of the vehicle body 1. A first motor 202 is fixedly installed inside one end of the fixed cover 201. A first bevel gear 203 is fixedly connected to the output end of the first motor 202. A second bevel gear 204 is rotatably connected to the upper end of the fixed cover 201. The first bevel gear 203 and the second bevel gear 204 are meshed. The top end of the second bevel gear 204 passes through the upper part of the fixed cover 201 and is fixedly connected to an atomizer 205. The output port of the atomizer 205 is connected to a nozzle 206. A fixed ring 207 is fixedly connected to the front end of the nozzle 206. A fan 208 is installed inside the fixed ring 207. A second motor 209 is fixedly installed on one side of the fixed ring 207. The output end of the second motor 209 passes through one side of the fixed ring 207 and is fixedly connected to one side of the fan 208. The other side of the fan 208 is rotatably connected to the inside side of the fixed ring 207.

[0052] Specifically, when fertilizing the seedlings after planting, nutrient solution needs to be added to the storage tank 301. During the actual process, the atomizer 205 is activated to atomize the nutrient solution inside the storage tank 301 and spray it out through the nozzle 206. The blower 208 is then activated to blow the atomized nutrient solution a further distance. The second motor 209 is activated to change the tilt angle of the blower 208, making the spraying angle of the nutrient solution flexible and variable. Combined with the first motor 202 driving the first bevel gear 203 to rotate, and the first bevel gear 203 driving the second bevel gear 204 to rotate, the main spraying direction of the atomizer 205 can be adjusted. Compared with traditional seedling fertilization devices, this allows for uniform spraying of all parts of the seedling, improving the spraying efficiency of the nutrient solution.

[0053] For further details, please refer to the appendix. Figure 6 -Appendix Figure 8 The near-ground spraying mechanism 3 includes a storage tank 301, an annular cylinder 302 connected to the bottom end of the storage tank 301, a toothed ring 303 rotatably connected to the bottom end of the annular cylinder 302, a third motor 304 fixedly installed on one side of the bottom end of the annular cylinder 302, a first gear 305 fixedly connected to the output end of the third motor 304, the first gear 305 meshing with the teeth on the inner wall of the toothed ring 303, a plurality of second gears 306 rotatably connected at equal intervals near the outer edge of the bottom end of the annular cylinder 302, the second gears 306 meshing with the teeth on the outer wall of the toothed ring 303, a spray head 307 fixedly connected to the bottom end of the second gears 306, and the spray head 307 communicating with the interior of the annular cylinder 302 through a connecting pipe 308;

[0054] Specifically, after the soil loosening work is completed, the spray head 307 is activated to spray nutrient solution close to the soil surface. During the spraying process, the lower spraying distance reduces the evaporation loss of the liquid nutrient solution, improving the problem of large nutrient solution loss in soil caused by the higher spraying position of traditional spraying devices. By activating the third motor 304, the first gear 305 fixedly connected to its output end can be driven to rotate. Under the driving action of the first gear 305, the clamping ring 303 will rotate, driving multiple ring-shaped second gears 306 to rotate, causing the spray head 307 to swing at a certain angle, improving the uniformity of spraying, increasing the spraying range, and making it more flexible and controllable.

[0055] For further details, please refer to the appendix. Figure 9 -Appendix Figure 10 The adjustable soil loosening mechanism 4 includes a fixed frame 401, an electric push rod 402 is installed at the top of the fixed frame 401, a connecting plate 403 is slidably connected inside the fixed frame 401, a rotating column 404 is rotatably connected to one side of the connecting plate 403, a first pulley 405 is fixedly connected to the top of the rotating column 404, a fourth motor 406 is fixedly installed on the other side of the connecting plate 403, a second pulley 407 is fixedly connected to the output end of the fourth motor 406, the first pulley 405 and the second pulley 407 are connected by a belt, a push frame plate 408 is fixedly connected to the top of the connecting plate 403, and the front end of the electric push rod 402 passes through the fixed frame 401 and is fixedly connected to the top of the push frame plate 408.

[0056] The bottom end of the rotating column 404 is fixedly connected to a multi-column frame 409. The top of the multi-column frame 409 is fixedly installed with a fifth motor 410. The output end of the fifth motor 410 is fixedly connected to a screw 411. A threaded block 412 is threadedly connected to the outer wall of the screw 411. Mounting frames 413 are rotatably connected to the lower part of the multi-column frame 409. Several cross shovels 415 are fixedly connected at equal intervals to the bottom of two opposite mounting frames 413. A sixth motor 416 is fixedly installed on one side of the other two opposite mounting frames 413. A soil loosening cutter wheel 417 is fixedly connected to the output end of the sixth motor 416. One end of the soil loosening cutter wheel 417 is rotatably connected to the inside side of the mounting frame 413. Support rods 414 are rotatably connected to the four sides of the threaded block 412. One end of the support rods 414 is rotatably connected to the top of the mounting frame 413 on the same side.

[0057] In this embodiment, when soil loosening is required, the electric push rod 402 is activated, causing its rod to move downwards. Under the pushing action of the electric push rod 402, the push plate 408 simultaneously presses against the connecting plate 403, causing the connecting plate 403 to also move downwards. This allows the bottom end of the multi-column frame 409 to pass through the middle of the annular cylinder 302 and approach the soil surface. At this time, the fifth motor 410 installed at the top of the multi-column frame 409 is activated, driving the screw 411 fixedly connected to its output end to rotate. Under meshing action, the threaded block 412 threaded to the outer wall of the screw 411 moves. When the threaded block 412 moves downwards, under the spreading action of the support rod 414, the four mounting brackets 413 gradually unfold. At this time, by activating two of the sixth motors 416, the loosening cutter wheel 417 can be driven to rotate, while the other two sixth motors... The cross shovel 415 installed under 416 is stationary. When the four mounting frames 413 are unfolded, the fourth motor 406 is started, which drives the second pulley 407 fixedly connected to its output end to rotate. The second pulley 407 drives the first pulley 405 to rotate, which in turn drives the rotating column 404 to rotate, thus rotating the entire multi-column frame 409. At this time, the electric push rod 402 is started again, which makes the rotating multi-column frame 409 press against the soil surface. With the cooperation of the loosening blade wheel 417 and the cross shovel 415, the soil is loosened. In actual work, the loosening range of the soil can be expanded or reduced by controlling the movement of the threaded block 412, while the loosening depth can be adjusted by controlling the extension length of the electric push rod 402, which improves the flexibility of loosening the soil and meets the operational needs of actual afforestation sites.
