Description

Technical Field

[0001] This invention relates to the field of red bean tree fertilization technology, specifically to an organic fertilizer application device for red bean tree planting. Background Technology

[0002] As a tree species with both ecological and economic value, the red bean tree requires a high degree of uniformity in nutrient supply during its growth, especially in the root fertilization stage, which directly affects root absorption efficiency and tree growth. Currently, the commonly used organic fertilizer application methods in red bean tree cultivation rely heavily on traditional manual trenching or ordinary agricultural machinery fertilization devices, which cannot meet the precision requirements of ring trench fertilization and have many technical shortcomings in practical applications.

[0003] Regarding circular trenching and positioning, existing fertilization devices generally lack the function of centering the trench around the red bean tree. When digging the circular trench, it is impossible to ensure that the trench is centered on the red bean tree, which easily leads to trench displacement and uneven distance between the trench and the roots. This results in an unbalanced distribution of organic fertilizer around the roots, with some areas having excess nutrients and others insufficient, seriously affecting the fertilization effect and thus restricting the balanced growth of the red bean tree. At the same time, most devices require separate trenching and burying operations, and additional manpower or equipment is needed to backfill the soil after trenching. This not only increases labor and time costs, but may also lead to fertilizer loss or volatilization due to untimely burying, reducing fertilizer utilization.

[0004] In terms of fertilizer delivery and blockage handling, traditional fertilization devices rely heavily on gravity in pipelines or simple spiral propulsion for organic fertilizer delivery, lacking efficient auxiliary delivery mechanisms. When the organic fertilizer has a high moisture content or uneven particle size, it is prone to stagnation and blockage in the outlet cylinder, fertilization fittings, and fertilization nozzles, leading to fertilization interruptions. Furthermore, existing devices lack automatic unblocking functions, requiring manual disassembly and cleaning after blockage, which not only affects operational efficiency but also increases maintenance difficulty. In addition, the fertilization mode of the fertilization nozzles is mostly continuous discharge, making it difficult to achieve precise, targeted fertilization, easily resulting in fertilizer waste. This lack of precision is particularly pronounced in scenarios involving fertilizing specific areas around the roots of red bean trees.

[0005] In terms of terrain adaptability and equipment flexibility, existing trenching fertilization equipment lacks ground contour-following capabilities. When operating in uneven planting areas such as mountains and slopes, it is impossible to adjust the trenching angle and depth according to the ground slope, resulting in inconsistent trench depths. This not only affects the burial depth of organic fertilizer but may also damage the shallow root system of the red bean tree, further affecting nutrient absorption. Furthermore, in most devices, the trenching module is fixedly connected to the frame, making it impossible to extend or retract. When moving the equipment in narrow planting areas or forest passages, its large size makes passage difficult. Moreover, subsequent maintenance and repair of the trenching module requires disassembling numerous parts, making the operation cumbersome and inconvenient.

[0006] In summary, current organic fertilizer application devices for red bean tree planting have significant shortcomings in terms of precision of circular trenching, fertilization efficiency, blockage handling, terrain adaptability, and equipment flexibility. There is an urgent need to develop a fertilizer application device with functions such as circular positioning, integrated trenching and burying, efficient transportation, automatic unblocking, and flexible adjustment to overcome the deficiencies of existing technologies and meet the actual needs of precise fertilization for red bean trees. Summary of the Invention

[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an organic fertilizer application device for planting red bean trees. Through the integrated trenching and burying module, it can perform circular trenching and simultaneous burying centered on the red bean tree. It also features a red bean tree positioning function, ensuring that the circular trench is centered on the red bean tree, guaranteeing a uniform distance between the trench and the tree's roots. This allows for even distribution of organic fertilizer around the tree's roots, improving the uniformity and equidistant nature of fertilization. The device achieves center positioning through contact with the red bean tree surface, ensuring the circular trench is centered on the tree and that the organic fertilizer is evenly distributed around the roots, avoiding uneven fertilization caused by trench misalignment.

[0008] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an organic fertilizer application device for planting red bean trees, comprising: The frame fixed to the fertilizer application machinery; A fertilization module is installed on the frame and is used to fertilize the roots of the red bean tree.

[0010] Preferably, a fan unit is fixedly connected to the side of the frame, and the fan unit is fixedly connected to the bottom of the outlet cylinder through a pneumatic pipe; The fan unit injects airflow into the discharge cylinder through the air pipe, so that the airflow carries organic fertilizer through the fertilizer pipe and discharges it to the fertilizer nozzle for orderly fertilization.

[0011] Preferably, at least three fertilizer nozzles are fixedly connected to the top of each of the three nozzles with a pulse nozzle, and at least three pulse nozzles are connected to the air outlet of the blower unit through a pulse tube. The blower unit injects pulsed airflow into the fertilizer nozzle through a pulse tube, enabling the pulsed airflow to perform pulsed, targeted fertilization of the organic fertilizer inside the fertilizer nozzle, and to perform pulsed unblocking operations when the organic fertilizer clogs the fertilizer nozzle.

[0012] Preferably, the trenching and burying integrated module includes an arc-shaped block, a motor for driving the arc-shaped block in an arc shape, and a feeding cylinder for driving the arc-shaped block to feed onto the fertilized surface. The bottom of the arc-shaped block is detachably equipped with at least three mounting brackets, which are arranged in an equidistant ring. The bottom of the at least three mounting brackets is hinged with three inclined U-shaped shovels, and torsion springs are installed at the hinges of the at least three U-shaped shovels. At least three fertilizer nozzles are respectively installed at the ends of the three U-shaped shovels.

[0013] Preferably, an arc-shaped guide rail block is slidably connected to the top of the arc-shaped block, and a gear disk for arc-shaped movement of the arc-shaped block is fixedly connected to the bottom of the motor. The outer surface of the arc-shaped block is provided with a set of teeth that mesh with the outer surface of the gear disk. The top of the arc-shaped guide block is fixedly connected to a mounting bracket, which includes a sliding frame and a fixed frame slidably connected to the sliding frame via a guide rod, and the motor is fixed to the top of the fixed frame; the feed cylinder is fixed to the sliding frame and is used to drive the fixed frame to feed.

[0014] Preferably, an arc-shaped positioning block is mounted on the top of the arc-shaped guide block via a telescopic frame with adjustable length, and several rotating rollers are rotatably connected inside the arc-shaped positioning block. The arc-shaped positioning block is aligned with the axis of the arc-shaped block. In the early stage of fertilization, the arc-shaped positioning block is used to make the axis of the red bean tree coincide with the axis of the arc-shaped block by contacting the outer surface of the red bean tree.

[0015] Preferably, the frame is provided with an adjustment module for extending and adjusting the trenching and burying integrated module; The adjustment module is used to extend or adjust the angle of the integrated trenching and burial module. The adjustment module includes two guide rails fixed to the bottom of one side of the frame. A sliding block is slidably connected to one side of each of the two guide rails. An auxiliary frame is rotatably connected to one side of each of the two sliding blocks via a rotating shaft. A transmission shaft is rotatably connected between the two auxiliary frames.

[0016] Beneficial effects Compared with the prior art, the present invention provides an organic fertilizer application device for planting red bean trees, which has the following beneficial effects: This invention utilizes an integrated trenching and burial module to perform circular trenching and simultaneous burial centered on a red bean tree. It also features a red bean tree positioning function, ensuring the circular trench is centered on the tree and maintains a uniform distance from the tree's roots. This allows for even distribution of organic fertilizer around the tree's roots, improving the uniformity and equidistant nature of fertilization. The module achieves centering by contacting the tree's surface, ensuring the trench is centered on the tree and that the organic fertilizer is evenly distributed around the roots. This avoids uneven fertilization caused by trench misalignment, and the soil naturally falls back into the fertilization trench, simultaneously completing the organic fertilizer burial process. This eliminates the need for a separate burial step, reducing labor and time costs.

[0017] This invention, through the setting of an arc-shaped positioning block, ensures that when the fertilization device makes a circular groove with the red bean tree as the center, the circular groove is opened with the red bean tree as the center, thus ensuring the uniformity and equidistantness of the fertilization in the circular groove. This solves the problem that existing equipment, due to the lack of positioning function, makes the circular groove not centered on the red bean tree, which affects the effect of subsequent circular groove fertilization.

[0018] This invention allows for the extension and adjustment of the trenching and burying integrated module via an adjustment module. This not only reduces the size of the equipment and improves its operation in different forestry or planting areas, but also facilitates the inspection and maintenance of the trenching and burying integrated module by staff, enhancing the ease of use of the equipment. The angle of the integrated trenching and burying module can be adjusted by the adjustment module, so that the integrated trenching and burying module can carry out circular trenching work for ground with different slopes. This solves the problem that the existing trenching fertilization equipment lacks ground contouring function, resulting in the trench depth being uneven, which affects subsequent fertilization.

[0021] 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.

[0022] Example 1: See attached document Figures 1 to 10 An organic fertilizer application device for planting red bean trees, comprising: A frame 100 fixed to the fertilizer application machinery; Fertilizer module 200 is installed on frame 100 and is used to apply fertilizer to the roots of red bean trees. The trenching and burying integrated module 300 is installed on one side of the frame 100. The trenching and burying integrated module 300 is used to open fertilizer trenches at the fertilizer application location and simultaneously bury the trenches containing fertilizer. The integrated trenching and burying module 300 allows for circular trenching and simultaneous burying centered on the red bean tree. It also features a red bean tree positioning function, ensuring that the circular trench is centered on the red bean tree and that the distance between the trench and the tree's roots is uniform. This results in the organic fertilizer being evenly distributed around the tree's roots, improving the uniformity and equidistant nature of fertilization. By contacting the surface of the red bean tree to achieve center positioning, the circular trench is ensured to be centered on the red bean tree, so that the organic fertilizer is evenly distributed around the roots, avoiding uneven fertilization caused by trench displacement. The soil can naturally fall back into the fertilization trench, completing the organic fertilizer burial simultaneously, eliminating the need for a separate burial process and reducing labor and time costs.

[0023] See attached document Figures 1 to 5 The fertilization module 200 includes at least three fertilization nozzles 201 and a fertilizer bin 202 fixed to the top of the frame 100. The bottom of the fertilizer bin 202 is fixedly connected to an outlet cylinder 203, which is connected to the inside of the at least three fertilization nozzles 201 through a fertilization pipe fitting. The organic fertilizer stored inside the fertilizer bin 202 is transported through the discharge tube 203 to at least three fertilizer nozzles 201 for fertilization. The fertilizer application fitting consists of a multi-port fitting and several fertilizer application tubes. One end of the multi-port fitting is connected to the bottom of the outlet cylinder 203, and the remaining ports are connected to different fertilizer application tubes. The other end of each fertilizer application tube is connected to a corresponding fertilizer nozzle 201. This structural design enables communication between the outlet cylinder 203 and at least three fertilizer nozzles 201, allowing organic fertilizer to be simultaneously delivered to multiple fertilizer nozzles 201, meeting the needs of simultaneous fertilization at multiple points and improving fertilization efficiency.

[0024] The inside of the discharge cylinder 203 is provided with a spiral drive shaft 204 for orderly discharge of organic fertilizer inside the fertilizer bin 202 through the discharge cylinder 203; The screw drive shaft 204 adopts an existing auger-type drive frame structure, and its power source is an electric motor. After the electric motor starts, it drives the screw drive shaft 204 to rotate. Utilizing the propulsive action of the screw blades, the organic fertilizer stored inside the fertilizer bin 202 is stably and orderly transported to the discharge cylinder 203, forming a continuous and uniform organic fertilizer supply flow. This prevents fertilizer from accumulating in the fertilizer bin 202 or interrupting the transport, ensuring the continuity of subsequent fertilization operations.

[0025] See attached document Figure 4 and Figure 5 A fan unit 205 is fixedly connected to the side of the frame 100. The fan unit 205 is fixedly connected to the bottom of the outlet cylinder 203 through the air pipe 206. The fan unit 205 injects airflow into the outlet cylinder 203 through the air pipe 206, so that the airflow carries organic fertilizer through the fertilizer pipe and is discharged to the fertilizer nozzle 201 for orderly fertilization. After the blower unit 205 starts, the generated airflow is delivered to the bottom of the outlet cylinder 203 through the pneumatic duct 206. The airflow creates a certain pressure within the outlet cylinder 203, propelling the organic fertilizer delivered by the spiral drive shaft 204, causing it to flow rapidly along the fertilization pipe and finally exit from the fertilization nozzle 201. This airflow-assisted method effectively improves the problem of poor organic fertilizer flow, preventing organic fertilizer from stagnating or clogging within the fertilization pipe, ensuring that the organic fertilizer reaches the fertilization location accurately and orderly, and improving fertilization precision.

[0026] Most existing fertilization devices rely solely on gravity transport of organic fertilizer through pipelines. When fertilization locations are dispersed and pipeline layouts are complex, organic fertilizer tends to accumulate within the pipelines due to insufficient flowability, making uniform replenishment impossible. This device overcomes the limitations of pipeline layout and organic fertilizer flowability by using airflow-assisted transport. Even under complex pipeline layout conditions, it can ensure stable delivery of organic fertilizer, solving the problem of low fertilization precision.

[0027] See attached document Figure 2 and Figure 3 At least three fertilizer nozzles 201 are fixedly connected to pulse nozzles 207 at their tops, and at least three pulse nozzles 207 are connected to the air outlet of the blower unit 205 through pulse pipes. The blower unit 205 injects pulsed airflow into the fertilizer nozzles 201 through the pulse pipes, enabling the pulsed airflow to perform pulsed targeted fertilization of the organic fertilizer inside the fertilizer nozzles 201 and to perform pulsed unblocking when the organic fertilizer clogs the fertilizer nozzles 201. The airflow generated by the blower unit 205 is also delivered to the pulse nozzles 207 through the pulse pipes, and the pulse nozzles 207 convert the airflow into pulsed airflow and inject it into the fertilizer nozzles 201. The pulsed airflow propels the organic fertilizer inside the fertilizer nozzles 201 out in a pulsed manner, allowing the organic fertilizer to accurately fall on the designated fertilization area, reducing fertilizer waste and improving fertilizer utilization, especially suitable for the precise fertilization needs of specific areas around the roots of red bean trees.

[0028] When organic fertilizer becomes clogged inside the fertilizer nozzle 201, the high-pressure impact of the pulsed airflow can disperse the clogged organic fertilizer, quickly restoring the unobstructed flow of the fertilizer nozzle 201. No manual disassembly and cleaning is required, reducing maintenance costs, ensuring smooth fertilization operations, and preventing uneven fertilization caused by clogged fertilizer nozzles 201.

[0029] See attached document Figure 2 , Figure 3 and Figures 7 to 10 The trenching and burying integrated module 300 includes an arc-shaped block 301, a motor 302 for driving the arc-shaped block 301 in an arc shape, and a feeding cylinder 303 for driving the arc-shaped block 301 to feed onto the fertilized ground. Motor 302 and feed cylinder 303 control: Motor 302 is a reversible electric motor, and feed cylinder 303 is a standard pneumatic actuator. Both are electrically connected to the external electrical control system mounted on the frame 100 or the fertilizer applicator. The electrical control system uses existing connection and coding methods to precisely control the rotation direction and speed of motor 302, as well as the extension and retraction amount and speed of feed cylinder 303. Motor 302 drives the arc-shaped block 301 to perform arc-shaped motion, while feed cylinder 303 drives the arc-shaped block 301 to feed towards the ground. The two work together to achieve precise control of the circular trenching operation.

[0030] The movement parameters of the arc-shaped block 301 are as follows: The opening angle of the arc-shaped block 301 is designed to be 90 degrees. This opening angle facilitates the wrapping of the red bean tree in the central area of ​​the arc-shaped block 301, providing suitable operating space for circular trenching. The movement angle range of the arc-shaped block 301 is set to be greater than or equal to 120 degrees and less than 270 degrees. When the three U-shaped shovels 305 rotate with the arc-shaped block 301 by more than or equal to 120 degrees, the movement trajectories of the three U-shaped shovels 305 can be pieced together to form a complete circle, thereby realizing circular fertilization operation without driving the arc-shaped block 301 to rotate a full circle, effectively shortening the trenching time and improving the efficiency of trenching and fertilization.

[0031] At least three mounting brackets 304 are detachably mounted on the bottom of the arc-shaped block 301, and the three mounting brackets 304 are arranged in an equidistant ring. At least three inclined U-shaped shovels 305 are hinged to the bottom of the at least three mounting brackets 304, and torsion springs are installed at the hinges of the at least three U-shaped shovels 305. At least three fertilizer nozzles 201 are respectively installed at the ends of the three U-shaped shovels 305. U-shaped shovel 305 installation and trenching principle: The U-shaped shovel 305 is detachably installed at the bottom of the arc-shaped block 301 via the mounting bracket 304. The mounting bracket 304 is arranged in an equidistant ring to ensure that the three U-shaped shovels 305 are evenly distributed at the bottom of the arc-shaped block 301. The U-shaped shovel 305 is designed to be inclined. When the arc-shaped block 301 moves in an arc shape under the drive of the motor 302, and is simultaneously fed into the ground under the drive of the feed cylinder 303, the inclined U-shaped shovel 305 contacts the ground and cuts into the soil. As the arc-shaped block 301 moves, the U-shaped shovel 305 continuously digs the soil, forming a circular fertilization trench.

[0032] Soil extraction and burial function: The U-shaped structure of the U-shaped shovel 305 has a guiding function. During the trenching process, the excavated soil moves upward along the inner wall of the U-shaped shovel 305 and is extracted from the end of the U-shaped shovel 305. When the fertilizer nozzle 201 delivers organic fertilizer into the fertilizer trench, with the continuous movement of the U-shaped shovel 305, the extracted soil will naturally fall back into the fertilizer trench, simultaneously burying the trench where organic fertilizer has been added. This achieves integrated trenching, fertilization, and burial operations, reducing the time and labor costs of separate burial processes.

[0033] The torsion spring has a dual function: Installing a torsion spring at the hinge of the U-shaped shovel 305 serves two purposes. First, when the U-shaped shovel 305 encounters obstacles such as roots or stones in the soil during trenching, the torsion spring undergoes elastic deformation, causing the U-shaped shovel 305 to rotate slightly around the hinge point. This adjusts the angle of the U-shaped shovel 305 to avoid obstacles, preventing damage and ensuring the continuity of trenching operations, thus improving trenching effectiveness and adaptability to complex soil environments. Second, when the U-shaped shovel 305 completes trenching and fertilization and returns to its original position, the elastic restoring force of the torsion spring maintains appropriate pressure between the U-shaped shovel 305 and the ground, gently pressing the fertilization trench after covering with soil. This enhances the contact tightness between the soil and the organic fertilizer, further improving the effect of buried fertilization and promoting the decomposition and absorption of organic fertilizer.

[0034] See attached document Figure 2 , Figure 3 and Figures 7 to 10 The top of the arc block 301 is slidably connected to an arc guide block 306, and the bottom of the motor 302 is fixedly connected to a gear disk 307 for the arc movement of the arc block 301. The outer surface of the arc block 301 is provided with a set of teeth that mesh with the outer surface of the gear disk 307. The motor 302 drives the toothed disc 307 to rotate, and finally drives the arc block 301 to move in a ring through the tooth assembly, thus driving at least three U-shaped shovels 305 to move in a ring, forming a ring grooving operation. The top of the arc-shaped guide block 306 is fixedly connected to a mounting bracket 308. The mounting bracket 308 includes a sliding frame and a fixed frame that is slidably connected to the sliding frame via a guide rod. The motor 302 is fixed to the top of the fixed frame. The air inlet cylinder 303 is fixed to the sliding frame and is used to drive the fixed frame to feed the air. The mounting bracket 308 is used for the installation of the motor 302 and the air inlet cylinder 303, which facilitates the motor 302 to drive the arc block 301 to perform arc-shaped movement, forming a circular trenching operation. The air inlet cylinder 303 drives the arc block 301 to perform feeding movement at the trenching position on the ground, forming a circular trenching operation and trenching at different depths.

[0035] Example 2: The difference from Example 1 is that; See attached document Figure 2 , Figure 3 and Figures 7 to 10 The top of the arc-shaped guide block 306 is equipped with an arc-shaped positioning block 309 via a telescopic frame with adjustable length, and the arc-shaped positioning block 309 is rotatably connected to several rotating rollers inside. The protective function of the rotating rollers: Several rotating rollers are rotatably connected inside the arc-shaped positioning block 309. The rotating rollers are made of smooth metal or engineering plastic. When the equipment performs positioning operations, the arc-shaped positioning block 309 contacts the outer surface of the red bean tree. The rotating rollers can rotate with the relative movement of the arc-shaped positioning block 309 and the red bean tree, converting sliding friction into rolling friction. This greatly reduces the friction between the arc-shaped positioning block 309 and the surface of the red bean tree, avoiding scratches or damage to the bark of the red bean tree and protecting its growth.

[0036] Adjustable telescopic frame: The telescopic frame adopts an existing adjustable-length telescopic support structure, and its length can be adjusted by bolt fixing or hydraulic drive. When it is necessary to replace the arc-shaped block 301 with one of different diameters to accommodate red bean trees of different diameters at breast height, the relative position between the arc-shaped positioning block 309 and the arc-shaped block 301 can be adjusted by adjusting the length of the telescopic frame. This ensures that the arc-shaped positioning block 309 can always make precise contact with the outer surface of the red bean tree, guaranteeing the effectiveness of the positioning function and improving the applicability of the device to red bean trees of different sizes. The arc-shaped positioning block 309 and the arc-shaped block 301 have their axes coincided. In the early stage of fertilization, the arc-shaped positioning block 309 is used to make the red bean tree and the arc-shaped block 301 coincide by contacting the outer surface of the red bean tree. The arc-shaped positioning block 309 and the arc-shaped block 301 are designed with their axes coincident. In the early stages of fertilization, the arc-shaped positioning block 309 is placed in contact with the outer surface of the red bean tree. Because their axes coincide, the axis of the arc-shaped block 301 is aligned with the center of the red bean tree. When the arc-shaped block 301 drives the U-shaped shovel plate 305 to create a circular trench, the trench is centered on the red bean tree, ensuring a uniform distance between the trench and the tree's roots. This allows the organic fertilizer to be evenly distributed around the tree's roots, improving the uniformity and equidistant nature of fertilization. This design solves the problem of existing equipment lacking a positioning function, causing the center of the circular trench to deviate from the red bean tree, thus affecting subsequent fertilization effectiveness.

[0037] Example 3: The difference from Example 1 is that; See attached document Figures 6 to 10 The frame 100 is provided with an adjustment module 400 for extending and adjusting the trenching and burying integrated module 300; the adjustment module 400 is used to extend or adjust the angle of the trenching and burying integrated module 300. By adjusting the extension of the trenching and burying integrated module 300 through the adjustment module 400, not only can the size of the equipment be reduced and its operation in different forestry or planting areas be improved, but it also facilitates the inspection and maintenance of the trenching and burying integrated module 300 by the staff in the later stage, and enhances the convenience of using the equipment. The angle of the trenching and burying integrated module 300 can be adjusted by the adjustment module 400 so that the trenching and burying integrated module 300 can perform circular trenching work for ground with different slopes. This solves the problem that the existing trenching fertilization equipment lacks ground contouring function, resulting in the trench depth being inconsistent and affecting subsequent fertilization.

[0038] The adjustment module 400 includes two guide rail frames 401 fixed to the bottom of one side of the frame 100. A sliding block 402 is slidably connected to one side of each of the two guide rail frames 401. An auxiliary frame 403 is rotatably connected to one side of each of the two sliding blocks 402 via a rotating shaft. A drive shaft 404 is rotatably connected between the two auxiliary frames 403. An adjustment cylinder 405 is hinged to the inner top of the frame 100. The telescopic end of the adjustment cylinder 405 is rotatably connected to the drive shaft 404. The sliding frame of the mounting bracket 308 is fixed between the two auxiliary frames 403. Driving principle of adjusting cylinder 405: Adjusting cylinder 405 is electrically connected to the electrical control system mounted on the frame 100 or the fertilizer applicator, and is controlled using existing connection and coding methods. The electrical control system controls the extension and retraction of adjusting cylinder 405. The extension and retraction end of adjusting cylinder 405 is rotatably connected to drive shaft 404. When adjusting cylinder 405 extends or retracts, it drives drive shaft 404 to rotate around the hinge point between auxiliary frame 403 and sliding block 402, thereby causing auxiliary frame 403 to adjust its fan-shaped angle around the axis of rotation on sliding block 402. Since the trenching and burying integrated module 300 is fixed to auxiliary frame 403 by mounting bracket 308, the angle adjustment of auxiliary frame 403 will synchronously drive the trenching and burying integrated module 300 to adjust its angle, enabling the trenching and burying integrated module 300 to adapt to different slopes and ensure that fertilizer trenches with uniform depth can still be dug on sloping terrain.

[0039] Height adjustment of sliding block 402 and guide rail 401: Sliding block 402 is slidably connected to guide rail 401 and can move up and down along guide rail 401. By driving sliding block 402 to slide on guide rail 401, the initial height of auxiliary frame 403 can be adjusted, thereby adjusting the initial height of trenching and burial integrated module 300. This height adjustment function, combined with the angle adjustment function of adjusting cylinder 405, enables adjusting module 400 to perform multi-dimensional adjustment of trenching and burial integrated module 300 in the angle and vertical direction, reducing dependence on feed cylinder 303 in trenching and burial integrated module 300, and reducing equipment manufacturing cost and maintenance difficulty; Both guide rails 401 are fixedly connected to springs 406 for pressing the sliding block 402 upwards. By fixing springs 406 to the guide rails 401, with one end connected to the guide rail 401 and the other end connected to the sliding block 402, the springs 406 are always in a state of pressing the sliding block 402 upwards. When the adjusting cylinder 405 retracts to drive the trenching and burial integrated module 300 to reset, the upward force of the springs 406 pushes the sliding block 402 upwards along the guide rails 401, causing the auxiliary frame 403 and the trenching and burial integrated module 300 to rise and reset first. After rising to a certain height, the adjusting cylinder 405 continues to retract, causing the auxiliary frame 403 and the trenching and burial integrated module 300 to flip and reset, ultimately achieving an orderly storage process of "rising and resetting - flipping and resetting" for the trenching and burial integrated module 300, reducing storage space and facilitating equipment transportation and storage. Both guide rail brackets 401 have a U-shaped limiting block 407 detachably fixed on one side, and the U-shaped limiting block 407 is used to guide the drive shaft 404. The U-shaped limiting block 407 is detachably fixed to one side of the guide rail frame 401. Its installation position is precisely calculated so that the distance between the U-shaped limiting block 407 and the sliding block 402 is equal to the length of the auxiliary frame 403. When the adjusting cylinder 405 drives the drive shaft 404 and the auxiliary frame 403 to a horizontal position, the drive shaft 404 is exactly at the top end of the U-shaped limiting block 407. At this time, if the adjusting cylinder 405 continues to lift, the drive shaft 404 will move downward along the U-shaped groove of the U-shaped limiting block 407, driving the auxiliary frame 403 and the trenching and burying integrated module 300 to descend synchronously. This achieves integrated operation where the trenching and burying integrated module 300 flips and extends before quickly descending to the trenching position, ensuring precise start-up of trenching operations and improving the ease of operation of the equipment.

[0040] Advantages of Extension and Adjustment: The extension and adjustment module 400 allows the trenching and burying integrated module 300 to be extended and adjusted. During equipment transportation or movement in narrow forestry or planting areas, the module 300 can be retracted for storage, reducing the overall size of the equipment and improving its mobility in complex environments. Simultaneously, the retracted state facilitates the inspection and maintenance of the module's components, reducing space limitations for maintenance operations and enhancing ease of use and maintenance efficiency.
