[0027] like Figures 1-8 As shown, this utility model embodiment provides an orchard precision fertilization device with controllable ditch depth, including a movable frame 100 for supporting the overall device. The upper end of the movable frame 100 is provided with a fertilizer storage hopper 200 for storing fertilizer. Both sides of the movable frame 100 are provided with ditching sections 400 for ditching operations. The ditching sections 400 are movably locked to the end of the fertilizer pipe 210 provided at the lower end of the movable frame 100. The fertilizer pipe 210 is connected to the fertilizer storage hopper 200.

[0028] The trenching section 400 includes a trenching plow 410 for trenching operations on the ground surface and a support frame 420 disposed inside the trenching plow 410 for supporting the trenching plow 410. The upper end of the support frame 420 is evenly provided with positioning holes 430 for mounting the trenching plow 410. The support legs disposed inside the trenching plow 410 are connected and fixed to the positioning holes 430 by bolts.

[0029] The upper end of the support frame 420 is evenly provided with positioning holes 430 for installing the furrowing plow 410. By connecting and fixing the support legs to different positioning holes 430, the height of the furrowing plow 410 can be adjusted, thereby flexibly controlling the furrowing depth. This is suitable for different types of fruit trees at different growth stages and meets diverse fertilization needs. Both sides of the mobile frame 100 are provided with furrowing sections 400, allowing the device to perform bilateral furrowing operations simultaneously during movement, greatly improving work efficiency. Since the furrowing sections 400 can be quickly disassembled and installed according to actual needs, the device's operational flexibility and adaptability to different environmental conditions are enhanced. By movably locking the furrowing section 400 to the end of the fertilizer pipe 210 located at the lower end of the mobile frame 100, and connecting the fertilizer pipe 210 to the fertilizer storage hopper 200, it is ensured that fertilizer can be directly applied to the pre-set position, improving the accuracy and efficiency of fertilization. This helps fruit trees better absorb nutrients, and precise fertilization not only reduces fertilizer waste but also lowers costs.

[0030] The support frame 420 is snapped onto one side of the fertilizer pipe 210, and one side of the support frame 420 is provided with an arc opening that matches the fertilizer pipe 210. It is fixedly installed at the end of the fertilizer pipe 210 by a U-shaped clamp 460, which facilitates the installation and fixation of the support frame 420.

[0031] The upper end of the support frame 420 is fitted with a traction rod 450 for traction, and the other end of the traction rod 450 is equipped with a soil covering plate 440 for covering soil. The two sets of soil covering plates 440 are arranged at an angle, which can be used to cover soil immediately after trenching and fertilization. The entire process of trenching, fertilization and soil covering can be completed in one go, which simplifies the operation process, greatly improves work efficiency, reduces labor costs and enhances the versatility and adaptability of the equipment.

[0032] The upper end of the support frame 420 is evenly provided with adjustment holes 421 for adjusting the height of the traction rod 450. The traction rod 450 is installed inside the adjustment hole 421 by fixing bolts. The installation method of the traction rod 450 can be adjusted according to actual needs to adapt to the working requirements of different depths.

[0033] The fertilizer storage hopper 200 is equipped with a stirring frame 240 for stirring the fertilizer inside. The rod ends of the stirring frame 240 are mounted on both sides of the fertilizer storage hopper 200 via bearings, and one end is connected to the output end of the drive box 110 via a transmission structure 250. The transmission structure 250 is driven by a sprocket and a chain. The stirring frame 240 can continuously stir the fertilizer inside the fertilizer storage hopper 200, effectively preventing the fertilizer from clumping or separating due to long-term storage, ensuring the consistency and uniformity of fertilizer composition each time it is applied, and improving the fluidity of the fertilizer, ensuring a smoother and more efficient fertilization process. The use of a sprocket and a chain as the transmission structure 250 has high transmission efficiency and stability, and can also withstand a large load.

[0034] The lower end of the fertilizer storage hopper 200 is equipped with a screw conveyor 220 for conveying materials. The screw conveyor 220 is installed inside the fertilizer pipe 210. One end of the fertilizer pipe 210 is equipped with a fertilizer outlet 230 for discharging materials. The fertilizer outlet 230 is connected to the inner cavity of the fertilizer pipe 210. The design of the screw conveyor 220 ensures that fertilizer can be transferred from the fertilizer storage hopper 200 to the fertilizer pipe 210 in a uniform and controllable manner, and finally accurately discharged through the fertilizer outlet 230. This greatly improves the accuracy and consistency of fertilization, so that each fruit tree can receive an appropriate amount of nutrients. The conveying method of the screw conveyor 220 can effectively control the output amount and speed of fertilizer, avoiding the fertilizer waste that may occur in the traditional fertilization process. At the same time, since the fertilizer outlet 230 is directly connected to the inner cavity of the fertilizer pipe 210, it ensures that the fertilizer can quickly and accurately reach the predetermined position, further improving the fertilizer utilization rate.

[0035] Two sets of spiral conveyor rods 220 are provided, and the inner ends of the two sets of spiral conveyor rods 220 and the stirring frame 240 are provided with transmission sprockets 221 for driving the spiral conveyor rods 220 to rotate. The transmission sprockets 221 are driven to rotate by the transmission chain 260 fitted on the upper end.

[0036] One end of the mobile frame 100 is provided with a front wheel 130 for assisting the mobile frame 100 in moving. A vertical frame 120 is provided on one side of the front wheel 130 for mounting and supporting the front wheel 130. The vertical frame 120 is fixedly installed on one side of the mobile frame 100 by bolts. A lifting part 300 is provided at the lower middle part of the mobile frame 100 for assisting the mobile frame 100 in moving. When the traction device moves the entire equipment, the front wheel 130 assists in moving.

[0037] The lifting unit 300 includes a McDham wheel 310 for assisting the movement of the mobile frame 100 and a fixed frame 330 on one side for mounting the McDham wheel 310. A connecting plate 340 is bolted to the fixed frame 330. The height of the fixed frame 330 is adjusted by a hydraulic rod 360 fixedly mounted on one side of the connecting plate 340. The hydraulic rod 360 is fixed by a U-shaped clamp 350 and adjusted by a traction device. The McDham wheel 310, with its unique structural design, provides excellent traction and maneuverability on various complex terrains. Combined with the design of the fixed frame 330 and the connecting plate 340, the entire device can not only move stably within the orchard but also adapt to different terrains. The adaptability to varying ground conditions, such as slopes and uneven surfaces, greatly enhances the equipment's versatility and flexibility. Through the coordinated use of the hydraulic rod 360 and the connecting plate 340, the height of the fixed frame 330 and the McDam wheels 310 mounted on it can be precisely adjusted. This allows operators to make fine adjustments according to specific operational needs, ensuring consistent and accurate fertilization depth, improving fertilization efficiency, and guaranteeing equipment stability. It also reduces safety risks caused by equipment tilting or instability. Furthermore, when the equipment is moved for extended periods, the hydraulic rod 360 can be extended, allowing the McDam wheels 310 and the front wheels 130 to work together for support, raising the rear trenching section 400 for easier equipment movement and preventing damage to the trenching section 400.

[0038] A movable frame 320 for mounting the McDam wheel 310 is movably mounted on one side of the fixed frame 330. The movable frame 320 is movably fitted onto the upper end of the limiting rod 331 set on one side of the fixed frame 330. A lifting spring 332 for protecting and buffering the movable frame 320 is movably mounted on the upper end of the limiting rod 331, so that the McDam wheel 310 can be adjusted up and down according to changes in terrain. This greatly enhances the device's adaptability to uneven ground, ensures stability and smoothness when traveling in complex terrain, and reduces bumps caused by changes in terrain. When the equipment travels on rough or hard ground, the lifting spring 332 can absorb the impact force, reduce the vibration transmitted to the entire device, and protect the internal components of the device from damage.

[0039] The working principle of a precision fertilization device for orchards with controllable ditch depth: The upper end of the support frame 420 is evenly provided with positioning holes 430 for installing the ditching plow 410. By connecting and fixing the support legs to different positioning holes 430, the height of the ditching plow 410 can be adjusted, thus flexibly controlling the ditch depth. This is suitable for different types of fruit trees at different growth stages, meeting diverse fertilization needs. The movable frame 100 has ditching sections 400 on both sides, allowing the device to perform bilateral ditching operations simultaneously during movement, greatly improving efficiency. To improve work efficiency, the trenching section 400 can be quickly disassembled and installed according to actual needs, enhancing the operational flexibility of the device and its adaptability to different environmental conditions. By movably mounting the trenching section 400 to the end of the fertilizer pipe 210 located at the lower end of the mobile frame 100, and connecting the fertilizer pipe 210 to the fertilizer storage hopper 200, it is ensured that fertilizer can be directly applied to the pre-set position, improving the accuracy and efficiency of fertilization. This helps fruit trees absorb nutrients better, and precise fertilization not only reduces fertilizer waste but also lowers costs.
