Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment technology, and in particular to a soil loosening and fertilization device and method for fruit tree planting. Background Technology

[0002] Before planting fruit trees, compacted soil needs to be loosened to improve its fluffiness and facilitate the survival and growth of the fruit trees. After planting, fruit trees need to absorb and consume a large amount of nutrients, and absorbing nutrients from the soil is one of the important ways for fruit trees to obtain nutrients. However, the content of various nutrients provided by the soil is relatively fixed. Therefore, in order to promote better growth of fruit trees after planting, the land needs to be pre-fertilized before planting so that the fertilizer can be integrated with the soil, increase the nutrients in the soil, facilitate the absorption of nutrients by the fruit trees after planting, and benefit the growth of the fruit trees.

[0003] Existing fertilization methods include trench fertilization, whole-orchard fertilization, and hole fertilization.

[0041] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0042] This embodiment describes a soil loosening and fertilization device and method for fruit tree planting, which relates to the field of agricultural machinery and equipment technology. It integrates a trench fertilization component 100, a hole fertilization component 200, and a whole-orchard fertilization component 300 on a vehicle frame 400, which can loosen and fertilize the forest soil in multiple layers.

[0043] Please see Figures 1 to 8 This embodiment discloses a soil loosening and fertilization device for fruit tree planting, comprising: a trench fertilization component 100, a hole fertilization component 200, a whole-orchard fertilization component 300, and a frame 400. The frame 400 can be simultaneously connected to the trench fertilization component 100, the hole fertilization component 200, and the whole-orchard fertilization component 300, providing connection and support. The trench fertilization component 100 can create trenches in the orchard for fertilization, the hole fertilization component 200 can perform drilling and hole fertilization operations, and the whole-orchard fertilization component can perform soil loosening and whole-orchard fertilization operations. The multiple components coordinate with each other to fertilize the orchard while loosening the soil.

[0044] The hole application component 200 includes a rotatable hole drilling unit 210, a lifting unit 220, and a fertilization unit 230. The fertilization unit 230 includes a fertilizer storage cylinder 231 and a spiral blade 232. The spiral blade 232 is disposed in the fertilizer storage cylinder 231 and is tightly fitted with the inner wall of the fertilizer storage cylinder 231 to form a spiral conveying structure. The middle part of the hole drilling unit 210 is rotatably connected to the spiral blade 232. The hole drilling unit 210 can drive the spiral blade 232 to rotate synchronously, realizing the conveying of organic fertilizer located in the fertilizer storage cylinder 231. When the hole drilling unit 210 rotates in the forward direction, it can drill holes at the bottom of the channel. The hole drilling unit 210 drives the spiral blade 232 to rotate in the forward direction, which can push the organic fertilizer in the fertilizer storage cylinder 231 from bottom to top, preventing the organic fertilizer from flowing down while stirring the organic fertilizer and promoting the uniform dispersion of the organic fertilizer. The drilling unit 210 rotates in the opposite direction, which drives the spiral blade 232 to rotate in the opposite direction. The spiral blade 232 pushes the organic fertilizer in the fertilizer storage cylinder 231 from top to bottom. By controlling the number of rotations of the spiral blade 232, the organic fertilizer can be quantitatively output into the hole.

[0045] The lifting unit 220 is fixedly connected to the drilling unit 210 and the fertilizer storage cylinder 231 respectively. The lifting unit 220 can drive the drilling unit 210 and the fertilizer storage cylinder 231 to rise and fall relative to each other, which serves as the feed motion during drilling and controls the depth of the hole.

[0046] The whole-field fertilization assembly 300 includes a rotatable spiked roller 310 and a support 320. The spiked roller 310 is rotatably connected to the support 320. The spiked roller 310 rolls on the ground, breaking up compacted soil and loosening it. The spiked roller 310 is hollow, with a storage cavity 311 for storing quick-acting fertilizer formed in the middle. The surface of the spiked roller 310 is provided with multiple discharge holes 312 that communicate with the storage cavity 311. As the spiked roller 310 rotates, the quick-acting fertilizer can be discharged from the discharge holes 312, completing the fertilization of the soil surface.

[0047] The frame 400 is connected to the trench fertilization assembly 100, the lifting unit 220, and the support 320. The trench fertilization assembly 100 is located at the head of the frame 400 and can pre-drill trenches. The lifting unit 220 is set perpendicular to the frame 400 and can control the raising and lowering of the hole drill unit 210 relative to the ground to complete the feeding motion of the hole drill. The support 320 is located at the rear of the vehicle body and can be mounted on the spiked roller 310 at the rear of the vehicle body to complete the leveling of the land.

[0048] It should be noted that a fertilizer box is provided on one side of the fertilizer storage cylinder 231. The fertilizer box is connected to the fertilizer storage cylinder 231 through a hose, and organic fertilizer can be added to the fertilizer storage cylinder 231 as needed to ensure a continuous supply of fertilizer in the fertilizer storage cylinder 231.

[0049] In some embodiments, please refer to Figure 2 and Figure 3 The drilling unit 210 includes a rotatable shaft 211 and a spiral drill bit 212. The spiral drill bit 212 is connected to the bottom of the shaft 211, and the spiral blades 232 are connected to the middle of the shaft 211. The relatively rotating shaft 211 can simultaneously drive the spiral blades 232 located in the middle and the spiral drill bit 212 located at the bottom to rotate, thus completing the corresponding operation.

[0050] The spiral blades 232 and the spiral drill bit 212 rotate in the same direction. The shaft 211 rotates in the forward direction, and the spiral drill bit 212 rotates in the forward direction, which can push the soil in the hole from bottom to top, thus completing the formation of the hole. The spiral blades 232 can push the organic fertilizer in the fertilizer storage cylinder 231 from bottom to top, while hindering the discharge of organic fertilizer and stirring the organic fertilizer to promote the uniform dispersion of organic fertilizer.

[0051] The shaft 211 rotates in the opposite direction, and the spiral blades 232 push the organic fertilizer in the fertilizer storage cylinder 231 from top to bottom. The organic fertilizer falls into the hole and comes into contact with the spiral drill bit 212. The spiral drill bit 212 reverses, which can input the organic fertilizer into the bottom of the hole.

[0052] In practical implementation, a servo motor is installed at the top of the rotating shaft 211. The servo motor is rotatably connected to the rotating shaft 211 and can control the direction and speed of the rotating shaft 211. The housing of the servo motor is connected to the lifting unit 220 through a connecting bracket to complete its fixation.

[0053] In some embodiments, please continue reading Figure 2 and Figure 3 The lifting unit 220 includes a lifting frame 221 and a movable lifting component 222. The lifting component 222 is a slider that cooperates with the lifting frame 221. The slider is slidably engaged with the lifting frame 221. The rotating shaft 211 and the fertilizer storage cylinder 231 are respectively connected to the slider. The slider can drive the rotating shaft 211 and the fertilizer storage cylinder 231 to move up and down synchronously, thereby realizing the control of the feeding motion.

[0054] In practical implementation, a drive unit is provided between the slider and the lifting frame 221. The drive unit can be a linear drive component such as a hydraulic rod or an electric push rod. The two ends of the linear drive component are connected to the frame 400 and the slider, respectively. The linear drive component can push the slider to move vertically along the lifting frame 221. The drive unit can also be a ball screw drive structure or a chain drive structure. The ball screw drive structure or the chain drive structure can directly drive the slider to move vertically along the lifting frame 221.

[0055] In some embodiments, please refer to Figures 4 to 6 The piercing roller 310 includes a roller body 313 and a central shaft 314. The central shaft 314 is axially inserted into the roller body 313 and fixedly connected to the roller body 313. Both ends of the central shaft 314 are rotatably connected to the bracket 320, which can ensure that the piercing roller 310 can rotate stably during operation. The combination of the roller body 313 and the central shaft 314 ensures the stability of the equipment during operation, avoids jamming or instability under high load or long-term operation, improves work efficiency and reduces the occurrence of mechanical failures.

[0056] The surface of the roller body 313 is provided with multiple roller spikes along the tangential direction of the roller body 313. The multiple roller spikes are equidistantly arranged around the roller body 313. When the roller body 313 rotates relative to the ground, under the action of its own weight, the roller spikes can penetrate into the soil, break up the compacted soil, leave holes in the soil, loosen the soil, and improve the aeration of the forest soil.

[0057] As a further embodiment, the central shaft 314 is provided with stirring blades 315 in the storage cavity 311 of the roller body 313. Multiple stirring blades 315 are arranged axially and at intervals along the central shaft 314. The central shaft 314 and the roller body 313 rotate relative to the support 320. The quick-acting fertilizer in the storage cavity 311 is always located at the bottom of the storage cavity 311 under the action of gravity. The stirring blades 315 can fully stir and break up the quick-acting fertilizer, ensuring its uniform distribution within the storage cavity 311. The stirring blades 315 also ensure that the fertilizer remains in a loose state, preventing caking or sedimentation, thus improving the fertilizer's fluidity. This allows the fertilizer to smoothly pass through the discharge hole 312 and enter the soil during fertilization, improving the smoothness and efficiency of the fertilization process.

[0058] In some embodiments, please refer to Figure 6 The roller body 313 has an openable and closable sealing door 316 in the middle. The sealing door 316 is detachably connected to the roller body 313 and can be connected to the roller body 313 by a buckle. During the fertilization process, the operator can add fertilizer to the roller body 313 to ensure that the fertilizer in the roller body 313 is always sufficient.

[0059] In some embodiments, please refer to Figure 2 A soil loosening and fertilization device for fruit tree planting also includes a spraying assembly 500, which comprises a spraying unit fixedly connected to a support 320. The spraying unit can evenly spray fast-acting fertilizer onto the soil surface or around the roots of the fruit trees. The sprayed water increases the moisture content of the soil surface, helping to improve soil structure and making the soil more suitable for root growth. Moist soil helps improve the solubility and absorbability of fertilizer, thereby enhancing fertilizer utilization efficiency.

[0060] In practical implementation, the spraying unit includes a spraying bracket 320 connected to a support 320 and spraying heads. Multiple spraying heads are installed on the spraying bracket 320, which is positioned behind the spiked roller 310. Water sprayed from the spraying heads can cover the soil treated by the spiked roller 310. The spraying assembly 500 also includes a water storage tank, which can continuously supply pressurized water to the spraying heads.

[0061] In some embodiments, please refer to Figure 1 and Figure 7The trench fertilization assembly 100 includes a trenching disc 110 and a fertilizer conveying unit 120. The cooperation between the trenching disc 110 and the fertilizer conveying unit 120 allows the trenching and fertilization processes to be performed continuously within the same operation. The trenching disc 110 and the fertilizer conveying unit 120 are sequentially connected to the frame 400 along its direction of movement. The trenching disc 110 first creates trenches in the soil, and then the fertilizer conveying unit 120 precisely delivers fertilizer into the trenches. This sequential operation reduces repetitive work and wasted time. The trench fertilization assembly 100 improves the overall efficiency of fertilization operations, making the fertilization process faster, more continuous, and more coordinated, reducing unnecessary pauses and repetitive operations, and improving overall operational efficiency.

[0062] In practical implementation, the trenching disc 110 is equipped with trenching teeth around its perimeter. Driven by an engine, the trenching disc 110 rotates at high speed, and the trenching teeth directly act on the soil, creating trenches in the land. The fertilizer conveying unit 120 is existing technology. The fertilizer conveying unit 120 includes a ground wheel and a fertilizer box. A fertilizer discharge device is connected to the lower part of the fertilizer box. At least one fertilizer discharge device is provided, and a discharge shaft connects the discharge devices. A discharge sprocket is connected to the left end of the discharge shaft. The discharge sprocket is connected to a ground wheel sprocket mounted on the ground wheel via a discharge transmission chain. A fertilizer delivery pipe is connected to the lower part of the fertilizer discharge device. The fertilizer delivery pipe is positioned opposite the trenching disc 110 and can output fertilizer into the trenches. The ground wheel is located on one side of the frame 400 and can contact the ground. The amount of fertilizer delivered is controlled by the number of rotations of the ground wheel.

[0063] In some embodiments, please refer to Figure 1 A soil loosening and fertilization device for fruit tree planting also includes a soil covering component 600 positioned between the hole application component 200 and the whole-orchard fertilization component 300. The soil covering component 600 includes soil covering plates 610 connected to the frame 400. The soil covering plates 610 are in two sets and are arranged in an inverted V-shape. The soil covering plates 610 can turn over the soil that has been turned out to the sides of the trench by the trenching plate 110 and push it back into the trench, completing the initial burial of the trench. Next, after the spiked roller 310 rolls over, the forest land can be completely leveled.

[0064] This embodiment describes a method for loosening soil and fertilizing fruit trees, which utilizes a device for loosening soil and fertilizing fruit trees, and includes the following steps:

[0065] S1: Trenching and Fertilizing

[0066] In forest clearings, a trench is created using the trench fertilization component 100, and fertilizer is evenly spread into the trench. The trench fertilization step is mainly used to improve soil permeability and provide basic nutrients.

[0067] Detailed process:

[0068] Trenching operation:

[0069] The furrowing disc 110 of the furrow fertilization component 100 is first driven by the frame 400 to open a strip-shaped furrow on the soil surface. The furrowing disc 110 forms regular grooves in the soil, and the furrowing depth and width can be adjusted according to the soil type (such as loose soil or heavy clay soil) to ensure that the furrow can accommodate an appropriate amount of fertilizer without damaging the basic structure of the soil.

[0070] Fertilization procedure:

[0071] While the furrows are being dug, the fertilizer delivery unit 120 evenly spreads fertilizer into the furrows according to the preset fertilizer type and dosage. The fertilizer can be organic fertilizer, compound fertilizer, or a special fertilizer customized according to the crop's needs. At this stage, the amount, type, and distribution of fertilizer are precisely controlled to ensure the uniformity and effectiveness of fertilization.

[0072] The creation of trenches helps loosen the soil, improves soil aeration, and increases the space for root respiration. Trench fertilization allows fertilizer to be concentrated around the roots, avoiding waste and improving fertilizer utilization.

[0073] S2: Fertilizer application through holes

[0074] The hole drilling unit 210 drills multiple holes at the bottom of the trench and injects organic fertilizer into these holes in a measured amount through the spiral blades 232. The hole fertilization step ensures that the fertilizer penetrates deep into the soil so that the fruit tree roots can better absorb nutrients.

[0075] Detailed process:

[0076] Forward drilling:

[0077] The shaft 211 of the hole-drilling unit 210 drives the auger bit 212 to rotate clockwise along the bottom of the trench, creating multiple regular holes in the soil. These holes are typically located at the bottom of the trench, and their depth and number can be adjusted according to soil type and the needs of the fruit trees. The clockwise rotation allows the drill bit to easily penetrate the soil without causing excessive soil disturbance.

[0078] Reverse fertilization:

[0079] After drilling the holes, the drilling unit 210 reverses, causing the spiral blades 232 to rotate and transport fertilizer from the fertilizer storage cylinder 231 into the drilled holes. The spiral blades 232 can quantitatively control the amount of fertilizer input, ensuring that the amount of fertilizer in each hole is uniform and avoiding fertilizer waste.

[0080] Application of organic fertilizer:

[0081] The fertilizers applied are usually organic, such as compost, humus, or bio-organic fertilizers. Because organic fertilizers have a longer release period, they decompose gradually in the soil, providing a continuous supply of nutrients to the fruit trees. Through this method of fertilization, organic fertilizers can penetrate deeper into the soil, promoting root growth in the fruit trees.

[0082] Fertilizer can be applied through planting holes, allowing it to penetrate deep into the active areas of the fruit tree's root system, thereby promoting root growth and efficient nutrient absorption. The quantitative output function of the spiral blade 232 ensures the accuracy of fertilizer application in each planting hole, avoiding over- or under-fertilization and improving fertilizer utilization.

[0083] S3: Fertilize the entire garden

[0084] The 310 licker roller assembly loosens the soil and applies fast-acting fertilizer throughout the orchard, comprehensively improving soil structure and providing fruit trees with readily available nutrients.

[0085] Detailed process:

[0086] Soil loosening operation:

[0087] The spiked roller 310 assembly consists of multiple metal spikes. The roller body 313 rotates to pierce the soil surface, breaking up clumps and loosening the soil. This process helps improve soil aeration and water permeability, making it easier for air, rainwater, and fertilizers to reach the roots of fruit trees, promoting healthy root growth.

[0088] Fertilization procedure:

[0089] The licker roller 310 not only loosens the soil but also stores fast-acting fertilizer. As the licker roller 310 rotates, the fertilizer is evenly released onto the soil surface through the discharge hole 312 of the roller body 313. The fast-acting fertilizer can dissolve quickly and be absorbed by the fruit tree roots, providing the fruit trees with the nutrients they need in the short term, especially during the fruit tree growing season or fruit enlargement period.

[0090] The 310 licker roller's soil-loosening function ensures improved soil structure, allowing roots to expand more easily and enabling water and oxygen to penetrate the root zone more fully.

[0091] The combination of trench fertilization, hole fertilization, and whole-orchard fertilization gradually improves soil permeability, looseness, and water retention capacity, thereby enhancing the overall quality of the soil.

[0092] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of the present invention.
