Description

Technical Field

[0001] This utility model relates to the field of tea planting equipment technology, specifically a portable ditch opener for fertilizing tea gardens in mountainous areas. Background Technology

[0002] In the management of mountain tea gardens, fertilization is an important part of the work, and trenching is a key step before fertilization. Mountain tea gardens have complex terrain, large undulations, and narrow and rugged roads, making it difficult for traditional large trenching machinery to enter the tea gardens. Even if they can enter, the mountainous terrain limits their operation, resulting in low trenching efficiency and easy damage to the tea trees and soil structure.

[0003] First, manual ditching is extremely inefficient. Mountainous tea gardens are vast, with complex terrain, significant elevation changes, and narrow, rugged roads. Relying on manual hoeing to dig sections one by one to complete the ditching of the entire tea garden is extremely time-consuming, making it difficult to prepare for fertilization in time for the agricultural season, thus affecting the tea tree's growth cycle. Second, labor costs are too high. Hiring a large number of people to ditch requires paying high labor costs, significantly increasing the production costs of the tea garden.

[0004] Furthermore, the quality of manual trenching is difficult to guarantee. Differences in physical strength and skill level among different operators result in inconsistent trench depth and width, failing to meet uniform standards. This, in turn, affects the even distribution of fertilizer and the absorption of nutrients by tea trees, reducing the effectiveness of fertilization.

[0005] In view of this, we propose a portable furrow opener for fertilizing tea gardens in mountainous areas. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a portable trencher for fertilizing tea gardens in mountainous areas.

[0007] The technical solution of this utility model is:

[0008] A portable ditcher for fertilizing tea plantations in mountainous areas includes a mounting frame. A central shaft is rotatably mounted within the mounting frame, and an auger blade is fixedly connected to the outer circumference of the central shaft. The auger blade is conical, with a smaller diameter near the front end. A drive motor with an output shaft coaxially fixed to the central shaft is mounted on the rear side of the mounting frame. An L-shaped frame is fixedly connected to the front of the mounting frame, and a support wheel is rotatably mounted on the bottom of the L-shaped frame. A handle is hinged to the top of the mounting frame via a hinge seat. A mounting box is fixedly connected to the rear outer wall of the mounting frame, and a battery is fixedly installed inside the mounting box. By setting a rotating central shaft within the mounting frame and connecting it to the conical auger blade, the drive motor drives the central shaft to rotate, enabling effective ditching. The conical design allows the front end to easily cut into the soil during ditching, while the rear end widens the trench, improving ditching efficiency and quality.

[0009] As a preferred technical solution, the handle includes a connecting block hinged to the hinge seat, a lower connecting rod fixedly connected to the top of the connecting block, and a double fork fixedly connected to the top of the lower connecting rod. This ensures a stable connection between the handle and the mounting frame while providing a certain degree of rotational flexibility, allowing operators to adjust the handle angle according to different working postures and operating habits for a more comfortable and efficient operating experience.

[0010] As a preferred technical solution, a telescopic rod is slidably connected inside the lower connecting rod, and the top of the telescopic rod is inserted into the bottom of the double fork rod. This allows the length of the handle to be adjusted, increasing convenience during use.

[0011] As a preferred technical solution, both the lower connecting rod and the double fork rod have a slot inside for insertion into the telescopic rod, and each slot contains a spring. The springs provide a cushioning effect to the handlebar, increasing comfort during pushing and pulling.

[0012] As a preferred technical solution, two limiting sleeves are fixedly connected to the outer circumference of the telescopic rod, ensuring that the telescopic rod remains detached from the lower connecting rod and the double fork rod during use. This prevents the telescopic rod from accidentally detaching during handle length adjustment or use, improving the safety and reliability of the handle structure.

[0013] As a preferred technical solution, an anti-slip sleeve is fixedly installed at both ends of the double fork away from the telescopic rod, and the outer circumferential wall of the anti-slip sleeve is provided with anti-slip teeth. This greatly increases the friction between the operator's hand and the handle.

[0014] As a preferred technical solution, a support block is fixedly connected to each of the four corners of the top of the mounting frame. When the handle is horizontal, the top of the connecting block is lower than the top of the support block. When the trencher is not in use and needs to be placed, the support block can provide stable support for the trencher, keeping it in a stable position and preventing it from tipping over and being damaged due to unstable placement. It should be added that when in use, the auger blades should be placed upwards.

[0015] As a preferred technical solution, the bottom of the support wheel is flush with the bottom of the front side of the mounting frame. This design ensures that the trencher remains stable during movement, preventing tilting or wobbling caused by the inconsistent height between the support wheel and the bottom of the mounting frame, thus ensuring the straightness of the trenching operation and the flatness of the trench.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a rotating central shaft within a mounting frame, connected to conical auger blades. A drive motor rotates the central shaft, enabling efficient trenching. The conical design allows the front end to easily cut into the soil during trenching, while the rear end widens the trench, improving trenching efficiency and quality. Attached Figure Description

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A portable ditch opener for fertilizing tea plantations in mountainous areas includes a mounting frame 1. A central shaft 20 is rotatably mounted inside the mounting frame 1. An auger blade 2 is fixedly connected to the outer circumference of the central shaft 20. The auger blade 2 is conical, with a smaller diameter at the front end. A drive motor 10, with its output shaft coaxially fixed to the central shaft 20, is mounted on the rear side of the mounting frame 1. An L-shaped frame 5 is fixedly connected to the front of the mounting frame 1, with a support wheel 50 rotatably mounted at the bottom of the L-shaped frame 5. A handle 3 is hinged to the top of the mounting frame 1 via a hinge seat 11. A mounting box 12 is fixedly connected to the rear outer wall of the mounting frame 1, and a battery is fixedly installed inside the mounting box 12. By setting a rotating central shaft 20 inside the mounting frame 1 and connecting it to the conical auger blade 2, the drive motor 10 drives the central shaft 20 to rotate, enabling effective ditching operations. The conical design allows the front end to easily cut into the soil during ditching, while the rear end widens the trench, improving ditching efficiency and quality.

[0027] In a preferred embodiment, the handle 3 includes a connecting block 30 hinged to the hinge seat 11. A lower connecting rod 31 is fixedly connected to the top of the connecting block 30, and a double fork rod 34 is fixedly fixed to the top of the lower connecting rod 31. This ensures a stable connection between the handle 3 and the mounting bracket 1 while providing a certain degree of rotational flexibility, allowing operators to adjust the angle of the handle 3 according to different working postures and operating habits for a more comfortable and efficient operating experience.

[0028] In a preferred embodiment, a telescopic rod 32 is slidably connected inside the lower connecting rod 31, and the top of the telescopic rod 32 is inserted into the bottom of the double fork rod 34. This allows the length of the handle 3 to be adjusted, increasing convenience during use.

[0029] In a preferred embodiment, both the lower connecting rod 31 and the double fork rod 34 have a slot for insertion into the telescopic rod 32, and each slot contains a spring 310. The springs 310 provide a cushioning effect to the handle 3, increasing comfort during pushing and pulling.

[0030] In a preferred embodiment, two limiting sleeves 33 are fixedly connected to the outer circumference of the telescopic rod 32. During use, the telescopic rod 32 remains connected to the lower connecting rod 31 and the double fork rod 34. This prevents the telescopic rod 32 from accidentally detaching during handle length adjustment or use, thus improving the safety and reliability of the handle 3 structure.

[0031] In a preferred embodiment, each end of the double fork 34 away from the telescopic rod 32 is fixedly equipped with an anti-slip sleeve 35, and the outer circumference of the anti-slip sleeve 35 is provided with anti-slip teeth. This greatly increases the friction between the operator's hand and the handle 3.

[0032] In a preferred embodiment, a support block 4 is fixedly connected to each of the four corners of the top of the mounting frame 1. When the handle 3 is horizontal, the top of the connecting block 30 is lower than the top of the support block 4. When the trencher is not in use and needs to be placed, the support block 4 can provide stable support for the trencher, keeping it in a stable position and preventing it from tipping over and being damaged due to unstable placement. It should be added that when in use, the auger blade 2 should be placed upwards.

[0033] As a preferred embodiment, the bottom of the support wheel 50 is flush with the bottom of the front side of the mounting frame 1. This design ensures that the trencher remains stable during movement, preventing tilting or wobbling caused by the inconsistent height between the support wheel 50 and the bottom of the mounting frame 1, thus ensuring the straightness of the trenching operation and the flatness of the trench.

[0034] When using this portable ditch opener for fertilizing tea gardens in mountainous areas, firstly, the drive motor 10, powered by a battery inside the mounting box 12, is turned on. The output shaft of the drive motor 10 drives the auger blades 2, which are coaxially fixed with the central shaft 20, to rotate. Because the auger blades 2 are conical and have a smaller diameter near the front end, the front end of the auger blades 2 can easily cut into the soil when the operator pushes the ditch opener forward. As the ditch opener moves and the auger blades 2 continue to rotate, the rear end gradually widens the trench, completing the ditching operation.

[0035] During trenching, the support wheels 50 at the bottom of the L-shaped frame 5 are flush with the front bottom of the mounting frame 1, providing stable support for the trencher and ensuring its stability during movement. This prevents tilting or wobbling and ensures the straightness of the trench and the flatness of the trench. When the trencher is not in use, the auger blades 2 are placed upwards. The support blocks 4 at the four corners of the top of the mounting frame 1 keep the trencher stable, preventing it from tipping over and being damaged, while also protecting the handle 3.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
