[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present disclosure clearer, the embodiments of the present disclosure are further described in detail below with reference to the embodiments and drawings, and the schematic embodiments and their descriptions are only used to explain the embodiments of the present disclosure, and not as a limitation of the embodiments of the present disclosure.

[0027] As Figure 1 shown, the high-efficiency tree planting and maintaining device for landscaping engineering of the application includes a fertilizer storage box 1, a quantitative feeding cylinder 2, a rotary digging tree planting head 3, a support 4 and a fertilizer conveying pipeline 5. The above-mentioned parts will be introduced in detail below.

[0028] The fertilizer storage box 1 in the device is a closed container for storing the fertilizer to be fed. A filling port is arranged at the top of the container for facilitating regular addition of fertilizer, and the bottom of the container is connected to the quantitative feeding cylinder 2, so as to realize continuous conveying of the fertilizer to the subsequent components. In order to prevent the fertilizer from being dampened by moisture, a moisture-proof structure can be arranged in the storage box, for example, a ventilation plate is arranged at the bottom or a moisture-absorbing material is laid on the wall surface of the box. In addition, a heating sheet can be additionally arranged outside the container to prevent the generation of condensed water, so as to ensure that the fertilizer is always in a suitable working state.

[0029] The quantitative feeding barrel 2 is one of the core components of the device, responsible for implementing the quantitative feeding of fertilizer. The quantitative feeding barrel 2 is internally installed with a screw propulsion mechanism 21, which uses a motor-driven rotating rod as the power source, and uses a push piece with a spiral groove to uniformly push the fertilizer entering from the fertilizer storage box 1 forward. In addition, one end of the quantitative feeding barrel 2 is connected to the fertilizer conveying pipeline 5, and the other end is fixed to the support 4, wherein the discharge port 22 adopts a special adjustable opening design (for details, please refer to Figure 4 ). This design allows the opening size to be adjusted by manual adjustment or an automatic control system to change the amount of fertilizer output each time. For example, when the saplings are larger, the user can increase the speed of the screw propulsion mechanism 21 and expand the opening size through the controller 12, while for smaller plants, the operating parameters are correspondingly reduced, thereby adapting to different planting scenarios and requirements.

[0030] The rotary digging tree planting head 3 is mainly used in the work process of digging planting holes in the soil. This component has a solid outer shell and a sharp soil drilling bit, which can easily cut into different types of soil layers to complete the excavation task. In terms of specific structure, the rotary digging tree planting head 3 is also specially provided with a fertilization area in communication with the fertilizer conveying pipeline 5, which directly applies the fertilizer transmitted through the fertilizer conveying pipeline 5 to the pre-set position in the dug hole during tree planting. The rotary digging tree planting head 3 is driven by an independent power source, and its overall height can be flexibly raised or lowered according to actual conditions to adapt to the specific needs of different types of trees for planting depth.

[0031] The support 4 is used to firmly support the entire device and maintain a reasonable layout between the components. Its basic structure is a stable frame composed of a group of combined horizontal and vertical beam structures, with the fertilizer storage box 1 and the quantitative feeding barrel 2 placed on top, and the rotary digging tree planting head 3 connected at the bottom, while ensuring that the relative positions of these components remain unchanged and have good synchronization. Considering the actual situation that the terrain may be complex, the bottom of the support 4 is equipped with walking wheels or other ground fixation facilities, which facilitate the quick transfer of the entire set of equipment by the staff according to demand or the fixation of the equipment at a fixed point in the work area for continued implementation of tasks.

[0032] The fertilizer conveying pipeline 5 connects the quantitative feeding barrel 2 and the rotary digging tree planting head 3, forming the transmission path inside the entire device, accurately guiding the fertilizer output from the quantitative feeding barrel 2 to the designated fertilization site. Such a pipeline is generally made of materials that are flexible and have excellent anti-aging ability, meeting the conveying pressure conditions while also considering certain stretching and bending performance to adapt to the physical impact caused by changes in the positional relationship between components during device operation. At the same time, the surface of the pipeline is usually coated with a corrosion-resistant coating to avoid damage and failure due to long-term erosion by strong chemical fertilizers.

[0033] Next, it explains how to solve the technical problem of avoiding fertilizer waste or excess by means of this feature. The key component in the device, the quantitative feeding cylinder 2, relies on its embedded screw propulsion mechanism 21 to ensure that each portion of fertilizer can be pushed at a uniform speed to the downstream link and eventually applied to the planting point. At the same time, due to the adjustable size of the discharge port 22, the operator can explicitly set the upper limit of the single delivery dose according to the different specifications of the planted trees. In this way, not only can the phenomenon of random spreading of fertilizer be eliminated, but also the required nutrients can be accurately matched for specific plants, thereby greatly reducing unnecessary consumption and environmental burden. In addition, since the entire process is carried out within a visible and controllable range, the probability of fertilizer over-standard due to judgment errors can also be significantly reduced, effectively achieving the goal of resource conservation.

[0034] As Figure 3 shown, in one embodiment, the fertilizer storage box 1 of the high-efficiency tree planting and maintenance device for landscaping engineering of the present application is provided with an inclined guide plate 6 at the bottom. The main function of the inclined guide plate 6 is to guide the fertilizer stored in the fertilizer storage box 1 to flow smoothly into the quantitative feeding cylinder 2 and to minimize fertilizer residue as much as possible, thereby improving the operating efficiency of the equipment. The inclined guide plate 6 forms an integrated structure with the fertilizer storage box 1 or is installed at the bottom area of the fertilizer storage box 1 through a detachable connection method, ensuring that it can guide the fertilizer to the outlet direction under the action of gravity. This position design fully utilizes the natural inclination force and material distribution characteristics to provide more reliable protection for the fertilization process.

[0035] For example, the inclined guide plate 6 can be made of stainless steel or other moisture-proof and corrosion-resistant materials, and its angle range can be adjusted between 10 degrees and 30 degrees to adapt to different types of fertilizer particle sizes, while ensuring that there is no obvious gap or blocking structure between the installed guide plate and the fertilizer storage box 1 to smoothly complete the fertilizer conveying work. The connection method between parts can also be further selected in the form of riveting or welding to ensure the overall stability.

[0036] As Figure 4As shown, in one embodiment, the quantitative feeding barrel 2 of the high-efficiency tree planting and maintenance device for landscaping engineering of the present application comprises a screw propulsion mechanism 21, which controls the fertilizer delivery rate by adjusting the rotation speed to meet the fertilizer amount requirement. The quantitative feeding barrel 2 is installed on the support 4 and is in communication with the fertilizer storage tank 1, and the fertilizer enters the inside of the quantitative feeding barrel 2 under the action of gravity. Among them, the screw propulsion mechanism 21 is composed of a variable frequency motor 7 and a screw shaft 8, and the two are connected to each other through a transmission assembly. The variable frequency motor 7 is installed at a position close to the upper end of the quantitative feeding barrel 2, and the screw shaft 8 is located in the cavity of the quantitative feeding barrel 2 and is arranged along the longitudinal axis thereof. Specifically, by adjusting the working parameters of the variable frequency motor 7, the rotation speed of the screw shaft 8 can be changed, thereby realizing precise control of the fertilizer pushing amount. At the same time, the outlet end of the quantitative feeding barrel 2 is provided with a discharge port 22 with adjustable size, which is used to further optimize the single fertilizer amount in combination with the rotation speed of the screw shaft 8.

[0037] For example, an industrial-grade AC frequency converter and a driving motor can be selected to form a power regulation system, which is connected to the external controller 12 and adjusts the output frequency according to the set program, finally realizing stepless adjustment of the rotation speed of the variable frequency motor 7. This way makes the screw shaft 8 able to change within a stable range, adapting to the fertilizer requirements of different plant types, and also facilitating collaborative work with other functional modules.

[0038] As shown in Figure 2 and Figure 4 As shown, in one embodiment, the discharge port 22 of the high-efficiency tree planting and maintenance device for landscaping engineering of the present application adopts a manually adjustable design to flexibly adjust the single feeding amount of the fertilizer. The discharge port 22 realizes manual adjustment of the opening size by mechanical means, and the scale identification disc 9 is used to assist the operator to quickly and intuitively judge the current opening size. The scale identification disc 9 is accurately installed on the outside of the discharge port 22, and the numerical value marked thereon corresponds one-to-one to the actual opening size of the discharge port 22, thereby improving the adjustment accuracy and avoiding operation deviation caused by human experience.

[0039] Specifically, the structure of the manually adjustable discharge port 22 mainly includes two parts: a movable plate that can be rotated and adjusted and a fixed plate. These two parts form the two side limiting boundaries of the discharge port 22, and the distance between them determines the width of the fertilizer outlet. Among them, the fixed plate is located at one end close to the bottom of the quantitative feeding barrel 2 and is in communication with the inner cavity thereof, while the movable plate is fixed near the fixed plate through a connecting piece and moves around a rotation axis, and the end thereof is equipped with a scale disc for identifying the relative position. In addition, in order to ensure the convenience of operation, an adjustment handle is stretched out from the outside of the quantitative feeding barrel 2, which is convenient for the user to control.

[0040] For example, the movable plate and the fixed plate can be connected through a form-fitting connection in the form of an embedded sliding groove, ensuring stable adjustment range and no shaking. At the same time, the scale mark disc 9 is directly combined with the rotating shaft through a concentric fixing mode, facilitating synchronous display of the opening value corresponding to the change in angle. The design of such a mechanical structure can reliably operate and meet the needs of long-term outdoor work.

[0041] As shown in Figure 4 In one embodiment, the high-efficiency tree planting and maintenance device for landscaping engineering of the present application is characterized in that the middle part of the fertilizer conveying pipeline 5 is provided with a flow sensor 11 for real-time monitoring of the fertilizer conveying amount, and linkage adjustment between the flow sensor 11 and the working state of the fertilization module is realized through a controller 12. By embedding the flow sensor 11 inside the fertilizer conveying pipeline 5 or attaching it to the outer wall of the pipeline, the use amount data of the fertilizer during conveying can be accurately collected. Specifically, the flow sensor 11 can be selected based on electromagnetic induction or differential pressure principle, which can convert the detected data into an electrical signal and transmit it to the controller 12 for analysis and judgment, thereby providing accurate reference for the work of the quantitative feeding barrel 2.

[0042] The controller 12 is electrically connected with the flow sensor 11 to receive and process the monitored flow information, and outputs adjustment instructions to each key component of the fertilization module, such as the screw propulsion mechanism 21 of the quantitative feeding barrel 2 and the adjustable opening size of the discharge port 22, through the preset algorithm. The above design realizes a closed-loop adjustment system from data collection to control feedback.

[0043] For example, the flow sensor 11 can be arranged in the specified area of the middle part of the fertilizer conveying pipeline 5 through the fixing clamp 13, ensuring good contact with the fluid in the pipeline while not affecting the structural integrity of the pipeline. At this time, the controller 12 receives the sensor signal through the circuit connection and sends corresponding adjustment instructions to modify the speed of the screw propulsion mechanism 21 or adjust the opening degree of the discharge port 22, so as to ensure that the amount of fertilizer in conveying meets the expected set value.

[0044] As shown in Figure 4 In one embodiment, the support 4 of the high-efficiency tree planting and maintenance device for landscaping engineering of the present application is designed to have multiple sets of fixing clamps 13. These fixing clamps 13 are arranged at specific positions on the support 4 and are respectively used for mounting the fertilizer storage box 1, the quantitative feeding barrel 2 and the fertilizer conveying pipeline 5, thereby improving the degree of close cooperation between the components. Among them, the number and distribution of the fixing clamps 13 can be adjusted adaptively according to different sizes and models of fertilization equipment. This setting can ensure the stability of each component during use, while enhancing the overall rigidity and reliability of the structure of the entire device.

[0045] The fixed clamp 13 is composed of adjustable clamp arms and locking units. The clamp arms wrap around the outer wall of the corresponding component, and the locking units fix them at a predetermined position on the support 4. Specifically, the fixed clamp 13 is divided into several combinations: one part is used to fix the fertilizer storage tank 1 at the bottom, so that it is vertically stable on the top of the support 4; another part is installed on the outer periphery of the quantitative feeding barrel 2 near the side of the screw propulsion mechanism 21, and is fixed in the middle of the support 4 to ensure horizontal stability; and the other part is used to support the fertilizer conveying pipeline 5, and multiple clamps are distributed along the pipeline direction to prevent the pipeline from moving or falling off due to bending or vibration. For example, in the technical implementation, the fixed clamp 13 can be designed in a way of elastic material or nested connection to adapt to the surface requirements of components with different diameters or shapes, thereby improving compatibility and assembly flexibility.

[0046] As shown in Figure 4 In one embodiment, the high-efficiency tree planting and maintenance device for landscaping engineering of the present application is characterized in that a buffer hopper 14 is arranged between the fertilizer conveying pipeline 5 and the rotary digging tree planting head 3. This design ensures that the fertilizer can be uniformly dispersed to the target area in different soil environments. The buffer hopper 14, as an intermediate structure, is installed between the end of the fertilizer conveying pipeline 5 and the feeding port of the rotary digging tree planting head 3, forming a transition connection between them. The buffer hopper 14 is composed of a main structure with a wide top and a narrow bottom. This structure can temporarily store the fertilizer transmitted from the fertilizer conveying pipeline 5 and guide it into the target fertilization path inside the rotary digging tree planting head 3 with more stable flow and state. By optimizing the connectivity between the end of the fertilizer conveying pipeline and the rotary digging tree planting head 3, the adaptability of the equipment to complex construction environments is improved.

[0047] For example, a hopper structure made of metal or engineering plastic with adjustable openings can be used to meet the design requirements. Specifically, the top flange of the buffer hopper 14 is firmly connected to the fertilizer conveying pipeline 5 through bolts or quick-mounting clamps, and the bottom discharge port 22 is connected to the feeding end interface of the rotary digging tree planting head 3. In addition, in order to ensure smooth flow of the fertilizer, anti-blocking baffles or guide vanes can be added to the inner cavity of the buffer hopper 14 to adjust the material flow direction.

[0048] As shown in Figure 1As shown, in one embodiment, the quantitative feeding barrel 2 of the high-efficiency tree planting and maintenance device for landscaping engineering of the present application is provided with a structure for facilitating the monitoring of the internal fertilizer storage state, specifically, an observation window 16 is additionally provided on the outer wall of the quantitative feeding barrel 2, which is used to real-time master the state and inventory of the fertilizer in the barrel. This structure can effectively prompt the user to take appropriate measures in time when the fertilizer is about to run out or clogging occurs, ensuring the continuity and accuracy of the fertilization process. Since the observation window 16 is directly fixed to the external position of the quantitative feeding barrel 2, it will not cause any interference to the internal fertilizer pushing mechanism.

[0049] Specifically, the observation window 16 can be made of transparent material and embedded in the side of the shell of the quantitative feeding barrel 2, for example, tempered glass or other materials with high wear resistance and good transparency, and tightly connected with the barrel body through a sealing ring to ensure the safety and sealing of the overall structure. In addition, the observation window 16 can also be designed in the form of a scale mark, further facilitating accurate estimation of the remaining capacity in the barrel. In order to enhance the durability and protection ability, in one embodiment, a protective frame can be additionally provided outside the observation window 16, so as to avoid mechanical damage from the outside.

[0050] For example, the transparent window piece is fixed to the specified area of the quantitative feeding barrel 2 through a bolt assembly, and the sealing effect is strengthened by using epoxy glue or other industrial adhesives. This technical solution not only meets the functional requirements, but also ensures the stable operation conditions of the entire maintenance device.

[0051] As shown, Figure 4 In one embodiment, the outlet position of the quantitative feeding barrel 2 of the high-efficiency tree planting and maintenance device for landscaping engineering of the present application is provided with a stirring homogenizer 17 for further optimizing the fertilization process. Specifically, the stirring homogenizer 17 is installed at the outlet of the quantitative feeding barrel 2 and communicates with the fertilizer conveying pipeline 5, and can directly act on the fertilizer about to enter the fertilizer conveying pipeline 5, preventing the internal caked material from affecting the uniformity of fertilization. The design of this component ensures that the fertilizer can still maintain an ideal particle state after passing through the quantitative feeding barrel 2, effectively reducing the flow instability or excessive accumulation problems that may be caused by caking. Since the stirring homogenizer 17 is located in the key connection area between the quantitative feeding barrel 2 and the fertilizer conveying pipeline 5, its operation needs to closely match the working rhythm of the screw propelling mechanism 21, so as to ensure the coordination of the entire device.

[0052] Specifically, the mixing and homogenizing unit 17 consists of multiple sets of staggered small-sized blades, driven by an independent power transmission unit. This power unit can be fixed in place via a reserved space on the support 4 and coupled to the power source of the entire device. For example, when the screw propulsion mechanism 21 gradually pushes the fertilizer towards the outlet side, the mixing and homogenizing unit 17 rotates at a specific frequency, using the cutting and crushing effect of the blades to disperse hard lumps in the fertilizer, making the processed fertilizer finer and more suitable for transport. This structural design meets the requirements for precise fertilization and avoids operational interruptions due to outlet blockage.

[0053] like Figure 2 As shown in one embodiment, the support 4 of the efficient tree planting and maintenance device for landscaping projects of this application integrates a weighing unit 18. The weighing unit 18 is located on the support 4 near the fertilizer storage tank 1, and is mainly used to monitor in real time the change in the weight of the remaining fertilizer after it passes through the quantitative dispensing cylinder 2 from the fertilizer storage tank 1. Specifically, the device utilizes the relative positional relationship between the weighing unit 18 and the fertilizer storage tank 1 to accurately capture the weight reduction caused by fertilization, and transmits this data to the control system for analysis and feedback. By monitoring the weight information during the dispensing process in real time, the problem of excessive or insufficient fertilizer caused by traditional manual estimation or mechanical parameter errors is avoided.

[0054] Furthermore, the weighing unit 18 consists of a high-precision sensing element and a signal processing module. The high-precision sensing element is fixed to a specific area on the bracket 4 to support the fertilizer storage tank 1 and directly senses its weight changes. Simultaneously, the signal processing module is connected to the sensing element via wiring to achieve data acquisition, transmission, and storage functions, thereby ensuring the entire device has reliable data feedback capabilities. For example, the weighing unit 18 can be embedded into the bracket 4 and securely connected by mounting a base plate, the base plate design of which must ensure it can withstand the pressure from the fertilizer storage tank 1 and maintain high measurement accuracy.

[0055] Specifically, an installation cavity can be reserved inside the bracket 4 to accommodate the various components of the weighing unit 18, and they can be fixed by bolts or clips. Subsequently, a force transmission component is installed in the supporting part of the fertilizer storage tank 1 to accurately apply the weight of the fertilizer to the sensing element to complete the measurement. This forms an integrated layout scheme that meets the requirements of structural compactness and functionality.

[0056] In actual operation, when the device is in use, the fertilizer in the fertilizer storage tank 1 flows into the quantitative feeding cylinder 2 by gravity, the screw propulsion mechanism 21 starts to uniformly push the fertilizer, and the discharge port 22 with adjustable opening size controls the amount of fertilizer released each time. Then, the quantitatively released fertilizer is transmitted to the set fertilization area inside the rotary digging tree planting head 3 through the fertilizer conveying pipeline 5. At the same time, the rotary digging tree planting head 3 digs a hole suitable for tree planting in the soil, ensuring that the fertilizer can be directly placed in the area required by the tree root system. The support 4 plays a fixing and supporting role in this process, keeping the positions of the components stable and cooperating with each other to achieve efficient tree planting and maintenance work.

[0057] The above is the preferred embodiment of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, several improvements and refinements can be made, which should also be considered within the scope of protection of the present application.
