Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a fertilizer application device for tea tree planting. Background Technology

[0002] Currently, the most common fertilization methods in tea tree cultivation are trench fertilization or rotary tillage fertilization. These methods often have problems such as insufficient fertilization depth, uneven mixing of fertilizer and soil, and easy damage to tea tree roots, making it difficult to meet the requirements of modern tea gardens for deep and precise fertilization.

[0003] Chinese invention patent application CN116508425A discloses a high-pressure soil loosening and fertilizer injection machine. This device uses a fertilizer injection component set between an upper and lower sealing cylinder. The high-pressure gas accumulated in the inner cavity of the fertilizer injection component pushes the fertilizer to burst out, causing the fertilizer to scatter into the surrounding soil, thereby expanding the fertilization area and promoting the full mixing of fertilizer and soil. Although this technology realizes fertilization by using high-pressure gas blasting, its structure is relatively complex and has high requirements for sealing performance. At the same time, in practical applications, it is difficult to accurately control the fertilization depth and uniformity, and the blasting impact can easily damage the tea tree root system.

[0004] Chinese utility model patent CN220935530U discloses a layered air-explosion device for deep tillage of forest land. The device uses a gasoline engine to drive a compressor to compress air and releases high-pressure gas through an air-explosion pipe to achieve deep soil loosening. Although the device can achieve deep soil loosening, it is not suitable for fertilization operations in tea plantation environments where root protection is required due to the bulky equipment, high noise, high energy consumption, and insufficient control precision during fertilization.

[0005] The two designs above achieve fertilization or soil loosening through high-pressure gas blasting and gas blasting, respectively. Although each has its advantages, they both have drawbacks such as complex equipment structure, insufficient control precision, and potential damage to tea tree roots. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a fertilization device for tea tree planting to solve the above-mentioned problems.

[0007] The purpose of this utility model is achieved through the following technical solution: a fertilizer application device for tea tree leaves, comprising a pressure tank, the top of which is connected to an external material and gas supply system via a pipe, a feed pipe fixedly connected to the bottom of the pressure tank via a pipe, a fertilizer application pipe fixedly connected to the end of the feed pipe away from the pressure tank, a gearbox fixedly connected to the top of the fertilizer application pipe, a small gear rotatably connected inside the gearbox, a large gear meshing with the outer end of the small gear, a feed rod fixedly connected to the large gear, a drill bit fixedly connected to the bottom end of the feed rod via a thread, an end cap fixedly connected to the top of the gearbox, a motor fixedly connected to the top of the end cap at a position corresponding to the small gear, a screw tube fixedly connected to the outer end of the fertilizer application pipe, a limit ring threadedly connected to the outer end of the screw tube, and the external material and gas supply system being used to supply materials and gas to the pressure tank, wherein the materials are in powder form and the gas is high-pressure gas.

[0008] The outer end of the drill bit has a conical structure, with the smaller diameter end of the conical structure facing away from the feed rod. A butterfly valve is fixedly connected to the pipe between the pressure tank and the feed pipe.

[0009] A screw is fixedly connected to the outer end of the feed rod, and the distance between the outer end of the screw and the inner wall of the fertilizer pipe is 5 to 10 millimeters.

[0010] An anti-rotation blade is fixedly connected to the outer end of the fertilizer pipe near the drill bit. The anti-rotation blade consists of multiple blades, and the length direction of the blades is set along the axis of the fertilizer pipe.

[0011] A drilling screw is fixedly connected to the outer end of the drill bit, and a fastening nut is provided at the top of the drill bit, and the fastening nut is threadedly connected to the feed rod.

[0012] The thickness of the pinion along its axis is several times that of the gearbox along its axis, and the gearbox can slide back and forth along the feed rod axis at the outer end of the pinion.

[0013] A handle is fixedly connected to the outer end of the fertilizer pipe near the gearbox, and the fertilizer pipe and the gearbox are fixedly connected by a flange.

[0014] The diameter of the outer end of the drill bit tip is larger than the diameter of the outer end of the fertilizer pipe bottom, and a shoulder strap is fixedly connected to the pressure tank.

[0015] The effective volume inside the pressure tank is more than four times the effective volume inside the fertilizer application pipe.

[0016] The beneficial effects of this utility model are:

[0017] First, the device adopts a reasonable ratio design between the volume of the pressure tank with a large effective volume and the volume of the fertilizer pipe, so that the pressure tank can store sufficient high-pressure gas and powdered materials, thereby ensuring a continuous and stable supply of materials during the fertilization process. The high-pressure gas and materials are fully mixed and accumulated in the pressure tank, providing a continuous driving force for the spraying process, ensuring that the materials are sprayed out evenly and achieving the effect of deep fertilization.

[0018] Secondly, through the precise transmission between the small and large gears in the gearbox, the feed rod drives the drill head to rotate stably and drill downwards. The drill head, combined with the spiral cutting structure of the drilling screw, can efficiently break up the soil, reduce drilling resistance, and enable the equipment to work smoothly even in harder soil. At the same time, the auger screw ensures that the material in the fertilizer pipe can be evenly pushed along the pipe during the drilling process, further ensuring sufficient material discharge and achieving efficient material conveying and discharge.

[0019] Furthermore, the anti-rotation blades prevent the fertilizer application tube from rotating relative to the drill bit by generating friction with the surrounding soil, thus ensuring that the fertilizer application tube and the drill bit always maintain a stable and fixed positional relationship. This design effectively ensures that the size of the spray channel formed is stable, so that high-pressure gas and materials can be sprayed evenly and accurately to the target soil area, achieving the purpose of precision fertilization.

[0020] In addition, the device is designed with the convenience of on-site operation in mind. The shoulder straps and handles make the equipment more flexible when moving and positioning it in the field. The flange connection structure ensures a firm fit between the components, which helps operators to adjust the fertilization depth and control the operation process more easily, thereby improving the overall operating efficiency and safety.

[0021] Finally, by using high-pressure gas to spray powdered materials, not only is the fertilizer evenly distributed deep within the soil, but the release of the high-pressure gas also loosens the soil. Compared to traditional trenching or rotary tillage fertilization, this deep fertilization method can achieve deeper and more precise fertilization without damaging the tea tree root system, promoting healthy growth of tea trees and improving fertilizer utilization and fertilization effect.

[0022] In summary, this utility model has significant advantages and practical value in improving the stability of material supply, efficient drilling and conveying, anti-rotation control, ease of operation, and deep and precise fertilization. It can effectively improve the fertilization effect of tea leaves in practical applications, promote the growth of tea trees and increase yield. Attached Figure Description

[0037] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0038] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0039] Example 1

[0040] like Figures 1 to 12 As shown, the fertilization device for tea tree leaf planting used in this embodiment includes the following main components:

[0041] The top of the pressure tank 1 is connected to an external material and gas supply system via a pipe to receive powdered materials (such as organic fertilizer) and high-pressure gas; the bottom of the tank is fixedly connected to the feed pipe 2 via a pipe.

[0042] One end of the feed pipe 2 is fixedly connected to the bottom of the pressure tank 1, and the other end is fixedly connected to the fertilizer pipe 3 away from the pressure tank 1, which is used to transmit materials and high-pressure gas.

[0043] The far end of the fertilizer pipe 3 is connected to the feed pipe 2, and the top end is fixedly connected to the gearbox 4 through a flange. A handle is fixedly connected to the outer end of the fertilizer pipe 3 near the gearbox 4, which makes it easy for the operator to hold and adjust the fertilization depth. At the same time, the effective volume inside the fertilizer pipe 3 is smaller than that of the pressure tank 1, and its volume ratio is controlled to be more than four times that of the effective volume of the pressure tank 1.

[0044] The gearbox 4 is fixedly connected to the top of the fertilizer pipe 3. It has a drive transmission mechanism inside, and a small gear 5 is rotatably connected inside. The small gear 5 meshes with a large gear 6 at its outer end. An end cover 9 is fixedly connected to the outer side of the top of the gearbox 4. A motor 10 is fixedly connected to the end cover 9 at a corresponding position to drive the transmission system.

[0045] The small gear 5 is located inside the gearbox 4, and its thickness along its axis is twice that of the large gear 6 along its axis, thus ensuring stable transmission. After the large gear 6 meshes with the small gear 5, it is fixedly connected to the feed rod 7 and can slide back and forth along the axis of the feed rod 7 to achieve fine-tuning of its position.

[0046] The feed rod 7 is fixedly connected to the large gear 6, and the bottom end of the feed rod is fixedly connected to the drill head 8 by a thread. The feed rod 7 serves as a component for transmitting rotational force and also realizes displacement adjustment during the drilling process.

[0047] The bottom of the drill bit 8 is fixedly connected to the feed rod 7 by threads; its outer end is designed as a tapered structure, and the end with the smaller diameter of the tapered structure faces away from the feed rod 7, which helps to reduce resistance when drilling into the soil; in addition, the diameter of the outer end of the top of the drill bit 8 is larger than the diameter of the outer end of the bottom of the fertilizer tube 3.

[0048] The outer end of the fertilizer pipe 3 is fixedly connected to a screw pipe 11. The outer end of the screw pipe 11 is connected to a limit ring 12 by a thread. The limit ring 12 plays a role in controlling the position of the fertilizer pipe 3 relative to the drill head 8 during operation, ensuring that a suitable gap can be formed between the fertilizer pipe 3 and the drill head 8 during drilling.

[0049] The butterfly valve is fixedly connected to the pipeline between the pressure tank 1 and the feed pipe 2. The butterfly valve is used to open or close the pipeline at the appropriate time to ensure that the powdered material and high-pressure gas in the pressure tank 1 can smoothly enter the fertilizer pipe 3 at the predetermined time.

[0050] The shoulder strap is fixedly connected to the pressure tank 1, making it easy for operators to carry and move the device when working in the field.

[0051] Work process

[0052] Filling materials and gases

[0053] Before use, powdered materials (such as organic fertilizer) and high-pressure gas are filled into the pressure tank 1 through an external material and gas supply system. The high-pressure gas and powdered materials are fully mixed and accumulated in the pressure tank 1 to form a predetermined pressure state.

[0054] Positioning and preparing for drilling

[0055] The operator carries the device and fixes the shoulder strap to the pressure tank 1 for easy carrying during field operations. After selecting the target fertilization location, the drill head 8 (with a conical outer end design) is placed on the soil surface to ensure full contact with the soil.

[0056] Start the transmission system

[0057] After the motor 10 is started, the motor 10 drives the small gear 5 in the gearbox 4 to rotate through the end cover 9. The small gear 5, with its larger thickness, stably drives the large gear 6 that meshes with it to rotate. At the same time, the large gear 6 and the feed rod 7 are linked together.

[0058] Drilling and synchronous descent

[0059] Driven by the transmission system, the feed rod 7 and the drill head 8 connected to it begin to rotate and drill into the soil. At the same time, since the fertilizer pipe 3 and the gearbox 4 are fixedly connected by a flange and are equipped with a handle, the fertilizer pipe 3 moves downward synchronously with the drill head 8 to maintain the overall structural coordination.

[0060] Limit control and formation of ejection channel

[0061] When the drill bit 8 reaches the set depth during the rotary drilling process, the limiting ring 12 (fixed to the outer end of the fertilizer pipe 3 by the screw tube 11) first contacts the soil surface, thereby restricting the fertilizer pipe 3 from continuing to move downward. At this time, the drill bit 8 continues to drill, driving the feed rod 7 and the large gear 6 to move downward together until the bottom end of the large gear 6 abuts against the inner wall of the gearbox 4, so that a gap is formed between the bottom end of the fertilizer pipe 3 and the top end of the drill bit 8.

[0062] Release materials and high-pressure gas

[0063] After the spraying channel is formed, the operator or automatic control device opens the butterfly valve, so that the high-pressure gas and powdered material in the pressure tank 1 are transported into the fertilizer pipe 3 through the feed pipe 2. Through the gap formed between the fertilizer pipe 3 and the drill head 8, the high-pressure gas pushes the powdered material to be sprayed evenly into the surrounding soil, so as to achieve deep fertilization.

[0064] Subsequent material handling and repetitive operations

[0065] To remove any remaining material that has not been completely sprayed out of the fertilizer pipe 3, the motor 10 continues to drive the transmission system, causing the feed rod 7 to rotate continuously, thereby further pushing out the remaining material. After the operation is completed, the device can be repositioned as needed to repeat the above filling, drilling and spraying process to complete the fertilization task at multiple work points.

[0066] Since the effective volume of the pressure tank 1 is at least four times that of the fertilizer pipe 3, the pressure tank 1 can store enough high-pressure gas and powdered materials, thereby ensuring that the spraying process has a long-lasting and stable pressure and continuous feeding capacity.

[0067] The drill head 8 adopts a conical structure design, with its smaller diameter end facing away from the feed rod 7, which helps to reduce drilling resistance and achieve efficient soil penetration. At the same time, the outer diameter of the top end of the drill head 8 is larger than the outer diameter of the bottom end of the fertilizer pipe 3, ensuring the formation of the spray channel and the uniform discharge of materials.

[0068] The transmission design of the small gear 5 and the large gear 6 in the gearbox 4, wherein the thickness of the small gear 5 is twice the thickness of the large gear 6, and the large gear 6 can slide along the axis of the feed rod 7, so that the transmission system remains stable and precise during rotation, which is beneficial to controlling the drilling depth and the downward movement distance of the fertilizer pipe 3.

[0069] The fertilizer pipe 3 is fixedly connected to the gearbox 4 via a flange, and a handle is fixedly connected to one end near the gearbox 4, which makes it easy for the operator to adjust the fertilization depth and hold the equipment stably during operation, ensuring the accuracy and safety of the operation.

[0070] The butterfly valve allows for the timed release of high-pressure gas and materials from the pressure tank 1. When drilling reaches the set depth and forms a spray channel, the powdered material and gas are quickly and evenly sprayed into the soil to achieve deep fertilization, while minimizing disturbance to the tea tree roots during operation.

[0071] The shoulder strap design fixedly connected to the pressure tank 1 facilitates carrying and deployment during on-site operations, improving the mobility and ease of use of the equipment.

[0072] In summary, this embodiment, through the reasonable configuration of the pressure tank 1, feed pipe 2, fertilizer pipe 3, gearbox 4, pinion 5, gear 6, feed rod 7, drill head 8, end cover 9, motor 10, solenoid 11, and limit ring 12, and in conjunction with auxiliary components such as butterfly valve and shoulder belt, achieves efficient, deep, and uniform fertilization operations. It not only ensures the full utilization of materials and gas, but also effectively reduces damage to the tea tree root system, and has significant practical value and promotion prospects.

[0073] Example 2

[0074] like Figures 1 to 12 As shown, this embodiment, based on the basic structure of embodiment 1, includes the following three improved components in addition to the following: pressure tank 1, feed pipe 2, fertilizer pipe 3, gearbox 4, pinion 5, gear 6, feed rod 7, drill head 8, end cap 9, motor 10, solenoid 11, limit ring 12, butterfly valve, and shoulder strap:

[0075] The screw 13 is fixedly connected to the outer end of the feed rod 7. Its installation position maintains a gap of 5 to 10 mm between its outer end and the inner wall of the fertilizer pipe 3. This design is beneficial to further push out the powdery material that has not been completely sprayed out in the fertilizer pipe 3 through the spiral conveying action of the screw 13 during drilling and material discharge, thereby improving the material conveying efficiency and discharge integrity.

[0076] To address the issue of the fertilizer application pipe 3 rotating with the drill head 8 during drilling, an anti-rotation blade 14 is fixedly connected to the outer end of the fertilizer application pipe 3 near the drill head 8. The anti-rotation blade 14 consists of multiple blades, and the length direction of each blade is set along the axis of the fertilizer application pipe 3. This anti-rotation structure prevents the fertilizer application pipe 3 from undergoing relative displacement due to the rotation of the drill head 8 by generating friction with the surrounding soil, thus ensuring the stability of the fertilizer application channel.

[0077] A drilling screw 15 is fixedly connected to the outer end of the drill head 8. The drilling screw 15 assists the drill head 8 in cutting the soil during the drilling process through its helical structure, making the drilling smoother. At the same time, a fastening nut is provided at the contact position at the top of the drill head 8. The fastening nut is threadedly connected to the feed rod 7, which not only ensures the reliable fixing of the drilling screw 15 and the drill head 8, but also facilitates the transmission of the rotational force of the feed rod 7, ensuring the overall transmission synchronization.

[0078] The remaining structure is the same as in Example 1, including:

[0079] The top of the pressure tank 1 is connected to an external material and gas supply system through a pipe, which supplies powdered materials (such as organic fertilizer) and high-pressure gas into the pressure tank 1;

[0080] The feed pipe 2 is fixedly connected to the bottom of the pressure tank 1 to transfer materials and gas to the fertilizer pipe 3;

[0081] The fertilizer pipe 3 is fixedly connected to the gearbox 4 via a flange, and a handle is provided on the outer end near the gearbox 4 to facilitate the operator in adjusting the fertilization depth.

[0082] The small gear 5 inside the gearbox 4 meshes with the large gear 6. The large gear 6 is fixedly connected to the feed rod 7 and can slide along the axial direction of the feed rod 7.

[0083] The outer end of the drill bit 8 adopts a tapered structure, with the smaller diameter end of the tapered structure facing away from the feed rod 7, and the outer diameter of its top end is larger than the outer diameter of the bottom end of the fertilizer tube 3.

[0084] The spiral tube 11 and the limiting ring 12 are used together to control the downward movement distance of the fertilizer pipe 3 during drilling;

[0085] The butterfly valve is fixedly installed on the pipeline between the pressure tank 1 and the feed pipe 2 to control the release of high-pressure gas and materials;

[0086] The shoulder straps are installed on the pressure tank 1 for easy on-site handling and arrangement.

[0087] Work process

[0088] Powdered material and high-pressure gas are simultaneously fed into pressure tank 1 through an external material and gas supply system, where the material and gas accumulate and form sufficient pressure.

[0089] The operator uses the shoulder straps fixed on the pressure tank 1 to carry the device to the work site. After selecting a suitable position, the drill head 8 is placed on the target soil surface. After starting the motor 10, the motor 10 drives the small gear 5 in the gearbox 4 to rotate through the end cover 9, thereby causing the large gear 6 and the feed rod 7 to rotate together, driving the drill head 8 to start rotating and drilling into the soil.

[0090] As the drill head 8 rotates, the auger screw 13 fixed to the outer end of the feed rod 7 begins to rotate synchronously. Its spiral structure, together with the feed rod 7, evenly conveys the internal material along the direction of the fertilizer pipe 3. The drilling screw 15 fixedly connected to the outer end of the drill head 8 effectively breaks up the soil by means of its thread cutting action, making the drilling process smoother. At the same time, the fastening nut set at the top of the drill head 8 and the threaded connection with the feed rod 7 ensure the tight cooperation between the various transmission components.

[0091] During the rotation of the drill head 8, the fertilizer pipe 3 is moved downward along the feed rod 7 until the limiting ring 12 contacts the soil surface, restricting the fertilizer pipe 3 from moving further downward. During this process, the anti-rotation blade 14 prevents the fertilizer pipe 3 from rotating relative to the drill head 8 through friction with the surrounding soil, ensuring that the fertilizer pipe 3 remains in a fixed position, so that a stable ejection channel can be formed between the drill head 8 and the fertilizer pipe 3.

[0092] As the drill head 8, feed rod 7, and large gear 6 continue to move downwards together until the bottom of the large gear 6 abuts against the inner wall of the gearbox 4, opening the gap between the bottom of the fertilizer pipe 3 and the top of the drill head 8, the operator or automatic control system will activate the butterfly valve. The high-pressure gas and powdered material accumulated in the pressure tank 1 will enter the fertilizer pipe 3 along the feed pipe 2 under pressure, and be evenly sprayed out through the gap between the fertilizer pipe 3 and the drill head 8, entering the surrounding soil to achieve a deep fertilization effect.

[0093] Subsequently, the motor 10 continues to drive the entire transmission system. The feed rod 7, together with the auger screw 13 fixed at its outer end, the drill head 8, and the drill screw 15 fixedly connected to the outside, rotate together to further push and discharge the powdery material that has not been completely sprayed out of the fertilizer pipe 3, thereby ensuring the thoroughness of the fertilization process.

[0094] During use, powdered materials, such as powdered organic fertilizer and high-pressure gas, are supplied to the pressure tank 1 through an external material and gas supply system. The high-pressure gas and materials accumulate in the pressure tank 1.

[0095] Next, a suitable location is found, and the drill head 8 is placed on the ground surface where fertilization is needed. At this time, the fertilizer pipe 3 is pressed against the top of the drill head 8 under the action of gravity, preventing soil from entering between the fertilizer pipe 3 and the drill head 8 during the drilling process. Then, the motor 10 drives the small gear 5 to rotate, which in turn drives the large gear 6 and the feed rod 7 to rotate together. The feed rod 7 then drives the drill head 8 to rotate. When the drill head 8 rotates, it drills into the ground through the drilling screw 15 until the limiting ring 12 is pressed against the ground surface. During this process, the fertilizer pipe 3 can be pushed down by stepping on the limiting ring 12.

[0096] During the drilling process, the drilling head 8 drives the fertilizer pipe 3 to move downward together. When the limiting ring 12 comes into contact with the ground surface, the drilling head 8 continues to drill. At this time, the drilling head 8, the feed rod 7 and the large gear 6 move downward together until the bottom of the large gear 6 comes into contact with the inner wall of the gearbox 4. At this time, the bottom of the large gear 6 is flush with the bottom of the small gear 5. At this time, the bottom of the fertilizer pipe 3 and the top of the drilling head 8 are opened.

[0097] Then, the butterfly valve is opened, and the compressed gas and waste in the pressure tank 1 enter the fertilizer pipe 3 through the feed pipe 2 under the pressure of the compressed gas. Then, it is sprayed out from between the fertilizer pipe 3 and the drill head 8 into the surrounding soil.

[0098] Then, the motor 10 continues to drive the feed rod 7, the auger screw 13, the drill head 8 and the drill screw 15 to rotate, pushing the material that has not been completely sprayed out of the fertilizer pipe 3 out of the fertilizer pipe 3;

[0099] Fertilizer can then be applied to the soil again through the pressure tank 1 as needed;

[0100] During the drilling process of the drill bit 8, the anti-rotation blade 14 interacts with the surrounding soil to prevent the fertilizer pipe 3 from rotating with the drill bit 8. When in use, the position of the limiting ring 12 on the screw tube 11 can be adjusted by rotating the limiting ring 12, thereby adjusting the depth of the fertilizer pipe 3 inserted into the soil.

[0101] After use, pull the fertilizer pipe 3 upwards to lift it off the ground, then you can work again.

[0102] By releasing powdered fertilizer with compressed gas, the fertilizer can be better integrated into the soil. The release of compressed gas into the soil can loosen and aerate the soil. At the same time, fertilization by drilling is more effective than conventional trenching or rotary tillage, allowing for deeper fertilization and reducing damage to the tea plant roots.

[0103] Depending on the soil conditions and operational requirements, the depth of the fertilizer application tube 3 inserted into the soil can be precisely controlled by adjusting the position of the limiting ring 12 on the screw tube 11. After the operation is completed, the device can be refilled with materials as needed and the fertilization operation can be carried out again at the next operation point.

[0104] The screw 13, which is fixedly connected to the outer end of the feed rod 7, uses its spiral structure to further push and discharge the material that has not been completely sprayed out in the fertilizer pipe 3, ensuring full utilization of the material and a more uniform spraying effect.

[0105] The anti-rotation blade 14, which is fixedly connected to the outer end of the fertilizer pipe 3 near the drill head 8, consists of multiple blades arranged along the axis of the fertilizer pipe 3. It effectively prevents the fertilizer pipe 3 from shifting due to rotation during drilling, thus ensuring the stability of the spray channel and the accuracy of fertilization.

[0106] The drilling screw 15 fixedly connected to the outer end of the drill head 8 and the fastening nut on its top are threadedly connected to the feed rod 7, which enables the drill head 8 to efficiently cut the soil during rotation, achieve reliable transmission in conjunction with the feed rod 7, and ensure that all transmission components work in a coordinated manner.

[0107] Through the synergistic effect of the aforementioned improved components, the fertilizer application pipe 3 and the drill head 8 are moved down synchronously and stably connected during the drilling process, ensuring the formation of a suitable spray channel. High-pressure gas and powdered materials are evenly released in this channel, allowing the fertilizer to better integrate into the soil. At the same time, the compressed gas released into the soil loosens the soil, thereby achieving a deeper and more precise fertilization effect than conventional trenching or rotary tillage, and effectively reducing damage to the tea tree roots.

[0108] In addition to inheriting the design of shoulder straps, butterfly valves, flange connection handles, etc. from Embodiment 1 for easy handling and operation, Embodiment 2 adds auxiliary conveying and anti-rotation mechanisms, enabling the equipment to adapt to different soil conditions in field operations, further improving the applicability and operational efficiency of the equipment.

[0109] In summary, based on Example 1, Example 2 further improves the overall performance of material conveying, drilling, and anti-rotation control by adding the auger screw 13, anti-rotation blades 14, and drilling screw 15 and their fastening structures. This enables the equipment to release powdered materials into the soil more efficiently and evenly during deep fertilization, ensuring fertilization depth and uniformity, while effectively protecting the tea tree root system. It has significant practical and promotional value.

It should be understood that the present utility model is not limited to the form disclosed herein and should not be regarded as an exclusion of other embodiments. It can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or related technologies or knowledge.
