Description

Technical Field

[0001] The invention relates to the technical field of fertilization devices, and in particular to a uniform fertilization device for forest management. Background Art

[0002] The nutrient content in forest soil is limited, especially in artificial forests or degraded forests. Excessive logging, soil erosion or nutrient loss often lead to insufficient soil fertility. Fertilization can supplement soil nutrients and promote the rapid and healthy growth of trees. Through fertilization regulation, the yield and quality of tree wood can be increased, and the fruit yield and quality of fruit economic forests can be improved. The disease, insect and stress resistance of trees can be improved, the carbon fixation capacity of forests can be enhanced, and the overall ecosystem service function can be improved. For barren hills and slopes with soil degradation or damaged forests, fertilization can accelerate the vegetation recovery process and improve the ecological environment. Forests are widely distributed and the terrain is diverse, so it is difficult for mechanical equipment to fully cover them. Different tree species and soil types have different nutrient requirements, so more precise fertilization methods are needed.

[0003] In the process of fertilizing tree species and soil, a fertilization device is one of the indispensable devices. Most of the fertilization devices on the market are not suitable for various terrain conditions and plant types, and fertilizing a large area cannot reduce the possibility of fertilizer dispersion or weathering. Therefore, a forest management uniform fertilization device is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a uniform fertilization device for forest management.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A uniform fertilization device for forest management comprises a support unit and a fertilization unit, two groups of fertilization units are arranged in parallel at both ends of the support unit, the fertilization unit comprises a fertilization pipe and an auxiliary material mechanism vertically inserted downwardly into the bottom of the fertilization pipe, a series pipe is inserted into the lower end surface of the auxiliary material mechanism, a pressing mechanism is arranged on the top of the series pipe, a bottom mounting piece is installed at the bottom of the series pipe, and a discharging mechanism is inserted into the inner cavity of the bottom mounting piece; The auxiliary material mechanism includes a material receiving tray and a ring array of mounting tubes arranged at the bottom of the material receiving tray, a funnel is clamped between three groups of the mounting tubes, and the bottom of the funnel is connected to the upper end surface of the dispersion mechanism.

[0006] Preferably, the dispersion mechanism comprises an assembly disk and a sleeve ring opened below the assembly disk, and a limiting ring block is arranged in an annular array on the outer end wall of the sleeve ring.

[0007] Preferably, the number of openings of the installation cylinder and the limiting ring block is the same, and the two are perpendicular to each other. There is a certain distance between the bottom of the installation cylinder and the upper end surface of the limiting ring block. The fertilizer to be fertilized enters the inner cavity of the fertilization tube downward and directly enters the inner cavity of the pressing mechanism downward. The auxiliary ingredients to be mixed with the fertilizer are poured into the upper part of the material receiving plate, and they will pass through the inner cavity of the installation cylinder and be discharged downward. Because the spraying position directly below the installation cylinder is consistent with the upper end surface of the limiting ring block, the auxiliary ingredients discharged from the inner cavity of the installation cylinder fall into the position directly above the limiting ring block, and the auxiliary ingredients blocked by the falling of the limiting ring block are The ingredients will fall in an irregular pattern, mixing and covering the auxiliary ingredients with the fertilizer on the soil or plants. This irregular diffusion pattern can better mix the auxiliary ingredients with the fertilizer to achieve a wider coverage and more uniform distribution of fertilization effects. The independent channel design for fertilization and auxiliary ingredients avoids blockage or waste during the premixing process. At the same time, direct mixing on the soil or plants reduces the intermediate links and improves fertilization efficiency. Through uniform distribution and mixing, fertilizer waste or local damage to plants and soil caused by the accumulation of a single fertilizer is avoided, resource utilization is improved, and negative impacts on the environment are reduced.

[0008] Preferably, the pressing mechanism comprises a storage bin and an internal frame installed on both sides of the inner cavity wall of the storage bin, and the inner end surface of the internal frame protrudes inwardly to provide a pushing motor.

[0009] Preferably, the storage bin is inserted through the sleeve ring from bottom to top and then enters the inner cavity of the funnel. The bottom of the storage bin is connected to the inner cavity of the series tube, and the fertilizer dropped downward from the fertilization tube will enter the inner cavity of the storage bin. Because the capacity of the fertilizer entering the inner cavity of the storage bin is large, the fertilizer will be squeezed in the inner cavity of the storage bin through the built-in frames arranged on both sides and the continuous peristalsis of the driving motor. During the extrusion process, the downward impact force of the fertilizer can be increased, and it can be effectively squeezed so that the fertilizer can be directly discharged downward from the discharge port. The dynamic process of peristaltic extrusion avoids the accumulation or blockage of the fertilizer in the discharge channel. The downward impact force generated during the extrusion process enhances the permeability of the fertilizer, especially in relatively compact soil, which can better help the fertilizer enter the soil and improve the fertilization effect. The fertilizer is quickly and smoothly discharged from the discharge port, which improves the fertilization efficiency. The extrusion process fully compresses and adjusts the fertilizer to ensure that the density and speed of the discharged fertilizer are relatively uniform, which helps to achieve a more uniform soil covering effect.

[0010] Preferably, the discharging mechanism includes a discharging frame and a discharging port opened in the middle position of the discharging frame, and the other three side end surfaces of the discharging frame away from the connecting horizontal bar are all provided with outriggers that diverge outward, and the lower end surface of the outriggers is arranged with discharging nozzles, and because the discharging nozzles arranged on the lower end surface of the outriggers are arranged in increasing height from inside to outside, the output ports of the outriggers on the outer sides are closer to the fertilization target, and the design realizes the layered discharge of fertilizer from the inside to the outside through the increasing height arrangement of the output ports of the discharging nozzles on the lower end surface of the outriggers, so that the area covered by the fertilizer is gradually expanded, which is suitable for fertilizing a large area; because the output ports of the outriggers on the outer sides are arranged in increasing height from inside to outside, the output ports of the outriggers are closer to the fertilization target. Closer to the fertilization target, the outer fertilizer can contact the target soil or plant more accurately, thereby optimizing the distribution of fertilizer and avoiding unnecessary waste; the incremental arrangement structure enables the fertilizer to be discharged evenly in different areas, reducing the problem of fertilizer concentration or sparseness caused by different discharge heights, and further improving the fertilization effect; the incremental design can effectively adapt to areas with undulating terrain, ensuring that the fertilizer can cover fertilization targets of various heights and positions, expanding the application scenarios of the equipment; the multi-level discharge method with the outer side closer to the target shortens the path of fertilizer to the target, reduces the possibility of fertilizer dispersion or weathering, and improves fertilization efficiency.

[0011] Preferably, the discharge nozzles provided on the lower end surface of the outrigger are arranged in increasing height from the inside to the outside.

[0012] Preferably, the series tubes penetrate downward through the inner cavity of the bottom mounting member, and the outer end walls of the series tubes are fitted to the inner cavity walls of the discharge port. When it is necessary to evenly fertilize plants or soil in a larger range, it is only necessary to block the bottom of the discharge port and connect the bottom end surface of the storage bin to the top of the discharge rack. At this time, the inner cavity, the outrigger and the discharge nozzle of the storage bin are interconnected, and the fertilizer can be evenly fertilized on a large area of ​​the soil or plants through the discharge nozzles arranged and distributed around the discharge rack. By blocking the bottom of the discharge port and changing the connection method of the device, the switching of the fertilization mode is achieved to adapt to fertilization scenes of different ranges and needs and enhance the versatility of the equipment. Due to the surrounding distribution design of the discharge nozzles, fertilizer can be discharged at multiple points to avoid excessive local fertility or waste caused by concentrated fertilization, ensuring more even fertilizer coverage. No complicated modification or additional devices are required, and the switching of large-area fertilization function can be completed through simple connection adjustment, which is convenient and quick.

[0013] Preferably, the support unit includes a positioning mechanism and a handheld positioning frame installed on both sides of the edge position of the outer end surface of the positioning mechanism, and the inner cavity of the positioning mechanism is laterally interspersed with connecting horizontal bars. The staff can hold both sides of the handheld positioning frame with both hands, and press the rear end surface of the positioning mechanism against the front chest of the staff, and use the hands, chest and positioning mechanism to form a stable triangular support structure. The staff can decide to hold any one of the upper and lower groups of handheld positioning frames according to their own usage habits. When the staff holds the upper handheld positioning frame, the working height of the overall device is reduced, but the stability in the working state is improved, especially during the fertilization process, it can effectively reduce the shaking of the equipment and improve the safety and comfort of use. When the staff holds the lower handheld positioning frame, the working height of the overall device is increased, and the fertilization unit of the overall device is in a tilted downward state due to its large weight and the fertilization material passes through its inner cavity, which is convenient for fertilizing fertilizers with higher water content, making it more suitable for processing fertilizers with high water content, ensuring uniform fertilization and convenient operation. The equipment design fully considers the usage habits of the staff, and provides higher flexibility by adjusting the handheld position and the support method to meet the needs of different operating environments.

[0014] Preferably, the positioning mechanism includes a mounting box and a built-in groove formed on the inner end wall of the mounting box, the inner cavity wall of the built-in groove is arranged with blocking pieces, and the side end face of the mounting box is provided with edge openings. When it is necessary to irrigate the plants in the forest, it is only necessary to insert the water pipe through the inner cavity of the built-in groove near the end of the staff, and the irrigation water flow can flow outward from the inner cavity of the built-in groove. At this time, the irrigation water will pass through the gaps between the multiple groups of blocking pieces arranged in an arranged manner, thereby blocking the passing irrigation water flow and disrupting the flow rate of the water discharged from the inner cavity of the built-in groove. The blocking and disrupting functions of gaps between multiple sets of blocking parts can effectively reduce the flow rate of water and make the water discharge more evenly, which is helpful to achieve uniform watering of plants and avoid excessive watering or local water accumulation. The gaps between multiple sets of blocking parts arranged in an array can disrupt the flow rate of discharged water and reduce the impact force of water flow, protect plants and their surrounding soil structure, reduce the risk of soil loss or plant root exposure due to strong water flow, can adapt to the irrigation needs of different plants in the forest, and by controlling the distribution and flow rate of water, it is suitable for various terrain conditions and plant types.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. It is convenient to fertilize fertilizers with higher water content, making it more suitable for handling fertilizers with high water content, ensuring uniform fertilization and convenient operation. The equipment design fully considers the usage habits of the staff and provides higher flexibility by adjusting the hand-held position and support method to meet the needs of different operating environments.

[0016] 2. When it is necessary to water the plants in the forest, it can effectively reduce the water flow rate and make the water discharge more evenly, which is helpful to achieve uniform watering of the plants and avoid excessive watering or local water accumulation. The gaps between the multiple groups of blocking parts arranged can disrupt the discharged water flow rate, reduce the impact force of the water flow, protect the plants and the surrounding soil structure, reduce the risk of soil loss or plant root exposure caused by strong water flow, and can adapt to the irrigation needs of different plants in the forest. By controlling the distribution and flow rate of the water flow, it is suitable for various terrain conditions and plant types.

[0017] 3. The auxiliary ingredients blocked by the falling of the restricted ring blocks will fall in an irregular pattern, and the auxiliary ingredients will be mixed and covered with the fertilizer on the soil or plants. This irregular diffusion pattern can better mix the auxiliary ingredients with the fertilizer to achieve a wider coverage and more uniform distribution of fertilization effects. The independent channel design of fertilization and auxiliary ingredients avoids blockage or waste in the premixing process. At the same time, direct mixing on the soil or plants reduces the intermediate links and improves the fertilization efficiency. Through uniform distribution and mixing, it avoids fertilizer waste or local damage to plants and soil caused by the accumulation of a single fertilizer, improves resource utilization, and reduces the negative impact on the environment.

[0018] 4. It can avoid the accumulation or blockage of fertilizer in the discharge channel. The downward impact force generated during the extrusion process enhances the permeability of the fertilizer, especially in relatively compact soil, which can better help the fertilizer enter the soil and improve the fertilization effect. The extrusion process fully compresses and adjusts the fertilizer to ensure that the density and speed of the discharged fertilizer are relatively uniform, which helps to achieve a more uniform soil coverage effect.

[0019] 5. By blocking the bottom of the discharge port and changing the connection method of the device, the fertilization mode can be switched to adapt to fertilization scenarios of different ranges and needs, and the versatility of the equipment can be enhanced. Due to the surrounding distribution design of the discharge nozzle, fertilizer can be discharged at multiple points, avoiding excessive local fertility or waste caused by concentrated fertilization, ensuring more uniform fertilizer coverage, without complex modification or additional devices, and switching of large-area fertilization function can be completed through simple connection adjustment, which is convenient and fast.

[0020] 6. Through the incremental arrangement of the discharge nozzle output ports on the lower end surface of the outrigger, the design realizes the layered discharge of fertilizer from the inside to the outside, so that the area covered by the fertilizer is gradually expanded, which is suitable for fertilizing a large area.

[0021] 7. The incremental arrangement structure enables fertilizer to be discharged evenly in different areas, reducing the problem of fertilizer concentration or sparseness caused by different discharge heights, further improving the fertilization effect. The incremental design can effectively adapt to areas with undulating terrain, ensuring that fertilizer can cover fertilization targets of various heights and positions, expanding the application scenarios of the equipment. The multi-level and outer discharge method closer to the target shortens the path of fertilizer to the target, reduces the possibility of fertilizer dispersion or weathering, and improves fertilization efficiency.

DETAILED DESCRIPTION

A funnel 223 is clamped between three groups of mounting tubes 222 . The bottom of the funnel 223 is connected to the upper end surface of the dispersion mechanism 224 .

[0026] The dispersion mechanism 224 includes an assembly plate 2241 and a sleeve ring 2242 opened below the assembly plate 2241 . The outer end wall of the sleeve ring 2242 is provided with a limiting ring block 2243 in an annular array.

[0027] The number of openings of the installation cylinder 222 and the limiting ring block 2243 is the same, and the two are perpendicular to each other. There is a certain distance between the bottom of the installation cylinder 222 and the upper end surface of the limiting ring block 2243. The fertilizer to be fertilized enters the inner cavity of the fertilizer pipe 21 downward, and directly enters the inner cavity of the pressing mechanism 24 downward. The auxiliary ingredients that need to be mixed with the fertilizer are poured into the upper part of the material receiving plate 221, and they will pass through the inner cavity of the installation cylinder 222 and be discharged downward. Because the ejection position directly below the installation cylinder 222 is consistent with the upper end surface of the limiting ring block 2243, the auxiliary ingredients discharged from the inner cavity of the installation cylinder 222 fall into the position directly above the limiting ring block 2243. The auxiliary ingredients blocked by the falling restriction ring block 2243 will fall in an irregular pattern, and the auxiliary ingredients will be mixed and covered with the fertilizer on the soil or plants. This irregular diffusion pattern can better mix the auxiliary ingredients with the fertilizer to achieve a fertilization effect with wider coverage and more uniform distribution. The independent channel design of fertilization and auxiliary ingredients avoids blockage or waste in the premixing process. At the same time, direct mixing on the soil or plants reduces the intermediate links and improves the fertilization efficiency. Through uniform distribution and mixing, fertilizer waste or local damage to plants and soil caused by the accumulation of a single fertilizer is avoided, resource utilization is improved, and the negative impact on the environment is reduced.

[0028] In the second embodiment, the pressing mechanism 24 includes a storage bin 241 and an internal frame 242 installed on both sides of the inner cavity wall of the storage bin 241. The inner end surface of the internal frame 242 protrudes inwardly to set a pushing motor 243; the storage bin 241 passes through the sleeve ring 2242 from bottom to top and then enters the inner cavity of the funnel 223. The bottom of the storage bin 241 is connected with the inner cavity of the series pipe 23. The fertilizer dropped downward from the fertilizer pipe 21 will enter the inner cavity of the storage bin 241. Since the capacity of the fertilizer entering the inner cavity of the storage bin 241 is large, it will be squeezed in the inner cavity of the storage bin 241 through the continuous peristalsis of the internal frame 242 and the pushing motor 243 set on both sides. During the process, the downward impact force of the fertilizer can be increased, and it can be effectively squeezed so that the fertilizer is directly discharged downward from the discharge port 262. The dynamic process of peristaltic extrusion can avoid the accumulation or blockage of fertilizer in the discharge channel. The downward impact force generated during the extrusion process enhances the permeability of the fertilizer, especially in relatively compact soil, which can better help the fertilizer enter the soil and improve the fertilization effect. The fertilizer is quickly and smoothly discharged from the discharge port 262, which improves the fertilization efficiency. The extrusion process fully compresses and adjusts the fertilizer to ensure that the density and speed of the discharged fertilizer are relatively uniform, which helps to achieve a more uniform soil coverage effect.

[0029] In the third embodiment, the discharging mechanism 26 comprises a discharging frame 261 and a discharging port 262 provided in the middle of the discharging frame 261. The other three side end surfaces of the discharging frame 261 away from the connecting horizontal bar 13 are all provided with outriggers 263 which diverge outwards. The lower end surface of the outriggers 263 is provided with discharging nozzles 264. Moreover, since the discharging nozzles 264 provided on the lower end surface of the outriggers 263 are arranged in a height increasing manner from inside to outside, the output ports of the discharging nozzles 264 on the outer side are closer to the fertilization target. Through the height increasing arrangement of the output ports of the discharging nozzles 264 on the lower end surface of the outriggers 263, the design realizes the layered discharge of fertilizer from inside to outside, so that the area covered by the fertilizer is gradually expanded, which is suitable for fertilization in a large area. fertilizer; because the output ports of the discharge nozzles 264 on the outside are closer to the fertilization target, the outer fertilizer can contact the target soil or plants more accurately, thereby optimizing the distribution of the fertilizer and avoiding unnecessary waste; the incremental arrangement structure enables the fertilizer to be discharged evenly in different areas, reducing the problem of fertilizer concentration or sparseness caused by different discharge heights, and further improving the fertilization effect; the incremental design can effectively adapt to areas with undulating terrain, ensuring that the fertilizer can cover fertilization targets of various heights and positions, expanding the application scenarios of the equipment; the multi-level discharge method with the outside closer to the target shortens the path of the fertilizer to the target, reduces the possibility of fertilizer dispersion or weathering, and improves the fertilization efficiency.

[0030] Embodiment 4, the discharge nozzle 264 provided on the lower end face of the outrigger 263 is arranged in increasing height from the inside to the outside, the series pipe 23 passes downward through the inner cavity of the bottom mounting member 25, and the outer end wall of the series pipe 23 is in contact with the inner cavity wall of the discharge port 262. When it is necessary to evenly fertilize plants or soil in a larger range, it is only necessary to block the bottom of the discharge port 262 and connect the bottom end face of the storage bin 241 to the top of the discharge rack 261. At this time, the inner cavity of the storage bin 241, the outrigger 263 and the discharge nozzle 264 are interconnected, and the fertilizer can be arranged around and distributed in the discharge port 262. The discharge nozzles 264 around the material rack 261 apply fertilizer to the soil or plants over a large area evenly. By blocking the bottom of the discharge port 262 and changing the connection method of the device, the fertilization mode can be switched to adapt to fertilization scenarios of different ranges and needs and enhance the versatility of the equipment. Due to the surrounding distribution design of the discharge nozzles 264, fertilizer can be discharged at multiple points to avoid excessive local fertility or waste caused by concentrated fertilization, ensuring more even fertilizer coverage. No complicated modification or additional devices are required, and the switching of large-area fertilization function can be completed through simple connection adjustments, which is convenient and quick.

[0031] Embodiment 5, the support unit 1 includes a positioning mechanism 11 and a handheld positioning frame 12 installed on both sides of the edge position of the outer end surface of the positioning mechanism 11, and the inner cavity of the positioning mechanism 11 is transversely interspersed with a connecting horizontal bar 13. The staff can hold both sides of the handheld positioning frame 12 with both hands, and press the rear end surface of the positioning mechanism 11 against the front chest of the staff, using the hands, chest and positioning mechanism 11 to form a stable triangular support structure. The staff can decide to hold any one of the upper and lower groups of handheld positioning frames 12 according to their own usage habits. When the staff holds the upper handheld positioning frame 12, the working height of the overall device is reduced, but during work The stability in the state is improved, especially in the fertilization process, it can effectively reduce the shaking of the equipment, improve the safety and comfort of use, when the staff holds the hand-held positioning frame 12 below, the working height of the whole device is increased, and the fertilization unit 2 of the whole device is in a tilted downward state due to its large weight and the fertilizer material passes through its inner cavity, which is convenient for fertilizing fertilizers with higher water content, making it more suitable for processing fertilizers with high water content, ensuring uniform fertilization and convenient operation. The equipment design fully considers the usage habits of the staff, and provides higher flexibility by adjusting the hand-held position and support method to meet the needs of different operating environments.

[0032] Embodiment 6, the positioning mechanism 11 comprises a mounting box 111 and a built-in groove 112 provided on the inner end wall of the mounting box 111, the inner cavity wall of the built-in groove 112 is arranged with blocking members 113, and the side end face of the mounting box 111 is provided with an edge opening 114. When it is necessary to irrigate the plants in the forest, it is only necessary to insert the water pipe through the inner cavity of the built-in groove 112 near the end of the staff, and the irrigation water flow can flow outward from the inner cavity of the built-in groove 112. At this time, the irrigation water will pass through the gaps between the multiple groups of blocking members 113 arranged in an arranged manner, thereby blocking the irrigation water flow passing through, and disrupting the irrigation water flow flowing through the built-in groove 11 The water velocity discharged from the inner cavity can be effectively reduced by the blocking and disturbing functions of the gaps of the multiple groups of blocking members 113, so that the water can be discharged more evenly, which is helpful to achieve uniform watering of the plants and avoid excessive watering or local water accumulation.

By controlling the distribution and flow rate of the water flow, it is suitable for various terrain conditions and plant types.

[0033] In summary, a uniform fertilization device for forest management comprises a support unit 1 and a fertilization unit 2. Two groups of fertilization units 2 are arranged in parallel at both ends of the support unit 1. The fertilization unit 2 comprises a fertilization pipe 21 and an auxiliary material mechanism 22 vertically inserted into the bottom of the fertilization pipe 21. A series pipe 23 is inserted into the lower end surface of the auxiliary material mechanism 22. A pressing mechanism 24 is arranged on the top of the series pipe 23. A bottom mounting member 25 is installed at the bottom of the series pipe 23. A discharging mechanism 26 is inserted into the inner cavity of the bottom mounting member 25. The staff can hold both sides of the handheld positioning frame 12 with both hands, and press the rear end surface of the positioning mechanism 11 against the front chest of the staff, so as to form a stable triangular support structure between the hands, the chest and the positioning mechanism 11. The staff can decide whether to hold the upper and lower groups of the handheld fertilization frame 12 according to their own usage habits. Any group of handheld positioning frames 12, when the staff holds the upper handheld positioning frame 12, the working height of the whole device is reduced, but the stability in the working state is improved, especially in the process of fertilization, it can effectively reduce the shaking of the equipment and improve the safety and comfort of use. When the staff holds the lower handheld positioning frame 12, the working height of the whole device is increased, and the fertilization unit 2 of the whole device is in a tilted downward state due to its large weight and the fertilizer material passing through its inner cavity, which is convenient for fertilizing fertilizers with higher water content, making it more suitable for handling fertilizers with high water content, ensuring uniform fertilization and convenient operation. The equipment design fully considers the use habits of the staff, and provides higher flexibility by adjusting the handheld position and the support method to meet the needs of different operating environments; When it is necessary to irrigate the plants in the forest, it is only necessary to insert the water pipe through the inner cavity of the built-in groove 112 near the end of the staff, and the irrigation water flow can flow outward from the inner cavity of the built-in groove 112. At this time, the irrigation water will pass through the gaps between the multiple groups of blocking members 113 arranged in an arranged manner, block the passing irrigation water flow, and disrupt the flow rate of the water discharged from the inner cavity of the built-in groove 112. The blocking and flow-disturbing functions of the gaps between the multiple groups of blocking members 113 can effectively reduce the flow rate of the water flow, so that the water flow can be discharged more evenly, which is helpful to achieve uniform irrigation of the plants and avoid excessive irrigation or local water accumulation. The gaps between the multiple groups of blocking members 113 arranged in an arranged manner can disrupt the flow rate of the discharged water flow, reduce the impact force of the water flow, protect the plants and the surrounding soil structure, reduce the risk of soil loss or plant root exposure caused by strong water flow, and can adapt to the irrigation needs of different plants in the forest. By controlling the distribution and flow rate of the water flow, it is suitable for various terrain conditions and plant types; The fertilizer to be applied is passed downward into the inner cavity of the fertilizer pipe 21, and directly passed downward into the inner cavity of the pressing mechanism 24. The auxiliary ingredients to be mixed with the fertilizer are poured into the upper part of the material receiving plate 221, and they will pass through the inner cavity of the mounting tube 222 and be discharged downward. Since the ejection position directly below the mounting tube 222 is consistent with the upper end surface of the limiting ring block 2243, the dropping position of the auxiliary ingredients discharged from the inner cavity of the mounting tube 222 is directly above the limiting ring block 2243, and the auxiliary ingredients blocked by the falling of the limiting ring block 2243 will fall in all directions in an irregular pattern. , the auxiliary ingredients are mixed with the fertilizer for fertilization on the soil or plants for covering. This irregular diffusion pattern can better mix the auxiliary ingredients with the fertilizer, achieving a wider coverage and more uniform distribution of fertilization effects. The independent channel design of fertilization and auxiliary ingredients avoids blockage or waste in the premixing process. At the same time, direct mixing on the soil or plants reduces the intermediate links and improves the fertilization efficiency. Through uniform distribution and mixing, it avoids fertilizer waste or local damage to plants and soil caused by the accumulation of a single fertilizer, improves resource utilization, and reduces the negative impact on the environment. The fertilizer dropped downward from the fertilizer pipe 21 will enter the inner cavity of the storage bin 241. Since the capacity of the fertilizer entering the inner cavity of the storage bin 241 is relatively large, the fertilizer will be squeezed in the inner cavity of the storage bin 241 through the continuous peristalsis of the built-in frames 242 and the driving motor 243 arranged on both sides. During the squeezing process, the downward impact force of the fertilizer can be increased, and it can be effectively squeezed so that the fertilizer can be directly discharged downward from the discharge port 262. Through the dynamic process of peristaltic squeezing, the accumulation or blockage of the fertilizer in the discharge channel is avoided. The downward impact force generated during the squeezing process enhances the permeability of the fertilizer, especially in relatively compact soil, which can better help the fertilizer enter the soil and improve the fertilization effect. The fertilizer is quickly and smoothly discharged from the discharge port 262, which improves the fertilization efficiency. The extrusion process fully compresses and adjusts the fertilizer to ensure that the density and speed of the discharged fertilizer are relatively uniform, which helps to achieve a more uniform soil coverage effect. When it is necessary to uniformly fertilize plants or soil in a larger range, it is only necessary to block the bottom of the discharge port 262 and connect the bottom end surface of the storage bin 241 to the top of the discharge rack 261. At this time, the inner cavity of the storage bin 241, the outrigger 263 and the discharge nozzle 264 are interconnected, and the fertilizer can be uniformly fertilized on a large area of ​​the soil or plants through the discharge nozzles 264 arranged and distributed around the discharge rack 261. By blocking the bottom of the discharge port 262 and changing the connection method of the device, the switching of the fertilization mode is realized to adapt to fertilization scenes of different ranges and needs, and enhance the versatility of the equipment. Due to the surrounding distribution design of the discharge nozzle 264, the fertilizer can be discharged at multiple points to avoid the phenomenon of excessive local fertility or waste caused by concentrated fertilization, ensuring more uniform fertilizer coverage. No complicated modification or additional devices are required, and the switching of the large-area fertilization function can be completed by simple connection adjustment, which is convenient and fast. Furthermore, since the discharge nozzles 264 disposed on the lower end surface of the outrigger 263 are arranged in a height increasing manner from the inside to the outside, the output ports of the discharge nozzles 264 on the outer side are closer to the fertilization target. Through the height increasing arrangement of the output ports of the discharge nozzles 264 on the lower end surface of the outrigger 263, the design realizes the layered discharge of fertilizer from the inside to the outside, so that the area covered by the fertilizer is gradually expanded, which is suitable for fertilizing a large area. Since the output ports of the discharge nozzles 264 on the outer sides are closer to the fertilization target, the outer fertilizer can contact the target soil or plants more accurately, thereby optimizing the distribution of the fertilizer and avoiding unnecessary waste; The incremental arrangement structure allows fertilizer to be evenly discharged in different areas, reducing the problem of fertilizer concentration or sparseness caused by different discharge heights, and further improving the fertilization effect; The incremental design can effectively adapt to areas with undulating terrain, ensuring that fertilizer can cover fertilization targets at various heights and locations, expanding the application scenarios of the equipment; The multi-level discharge method with the outer side closer to the target shortens the path of fertilizer to reach the target, reduces the possibility of fertilizer dispersion or weathering, and improves fertilization efficiency.
