Description

Technical Field

[0001] This invention relates to a device, particularly a fertilization device, and especially a device for uniformly and quantitatively fertilizing tea plants. Background Technology

[0002] As an important economic crop, the yield and quality of tea directly affect the economic benefits of tea farmers and the sustainable development of the tea industry. Scientific fertilization is one of the core aspects of tea garden management, significantly impacting bud break rate, 100-bud weight, internal substance accumulation, and stress resistance. Traditional tea garden fertilization methods mainly rely on manual spreading or simple mechanical application, which have many technical shortcomings that urgently need to be addressed.

[0003] 1) First, the uniformity of fertilization is poor. Manual fertilization is greatly affected by the physical strength, experience, and subjective judgment of the workers, which easily leads to uneven distribution of fertilizer, over-application, or omissions. This results in significant spatial differences in soil fertility in tea gardens. In some areas, excessive fertilization may cause root burn, soil salinization, and nutrient loss, while in other areas, insufficient nutrients may lead to weak growth and low yield. Ultimately, this results in inconsistent yield and quality in the overall tea garden, making it impossible to achieve standardized production.

[0004] 2) Secondly, the precision of fertilizer application control is low. Traditional methods make it difficult to accurately control the amount of fertilizer applied per unit area. Often, it is estimated based on experience, which involves a large degree of randomness. Excessive fertilization not only increases production costs but also leads to fertilizer waste and serious environmental non-point source pollution, such as eutrophication of water bodies. Insufficient fertilization, on the other hand, cannot meet the growth needs of tea trees and affects their normal growth and development. Therefore, achieving quantitative fertilization is the key to improving fertilizer utilization and practicing the green agricultural concept of "reduced application and increased efficiency".

[0005] 3) Finally, operational efficiency and labor costs are prominent issues. With changes in the rural labor force structure, agricultural labor costs are constantly rising. The traditional fertilization model that relies on manual labor is inefficient and labor-intensive, which has become a bottleneck restricting the large-scale and intensive development of tea gardens.

[0006] Therefore, there is an urgent need in this field for a new type of fertilization equipment specifically designed for tea gardens, in order to achieve mechanization and precision in tea garden fertilization, thereby improving fertilizer utilization, ensuring stable tea quality, reducing production costs, and reducing environmental pollution.

[0007] Chinese utility model patent CN 218941750 U discloses a tea tree fertilization device. This device includes a cart, a controller, steering wheels, a liquid fertilizer tank, a water pump, a battery, a drive motor, drive wheels, and an injection device. The controller is mounted on the handle of the cart, the injection device is located to the left of the handle, the liquid fertilizer tank is located to the left of the injection device, the water pump is located above the liquid fertilizer tank and connected to the injection device via a hose, the battery is located to the left of the liquid fertilizer tank, and the drive motor is located below the battery. The drive motor is connected to the drive wheels via a chain. This device uses an injection method for fertilization, which has low efficiency and injects liquid fertilizer directly into the tea tree roots, potentially causing excessive concentration and root burn. It is not suitable for efficient fertilization of large areas of tea trees. Summary of the Invention

[0008] The present invention aims to overcome the shortcomings of the prior art by providing a tea uniform and quantitative fertilization device that can efficiently and precisely apply fertilizer to large-area tea gardens, thus meeting the needs for efficient, precise, quantitative, and economical fertilization of large-scale tea gardens.

[0009] The technical solution adopted by this invention to solve its technical problem is as follows: This tea uniform quantitative fertilization equipment includes a base frame, on which a soil-shoveling uniform quantitative fertilization device and a soil-returning device located behind the soil-shoveling uniform quantitative fertilization device are installed; the soil-shoveling uniform quantitative fertilization device includes a pair of opposing vertical rods, the bottom ends of which are fixed with trenching shovels, the heads of which are pointed and curved downwards; a support is installed on the base frame, and a fertilizer granule holding box is installed on the support; both sides of the bottom of the fertilizer granule holding box are provided with hoppers, and both sides of the hoppers are fixed with opposing cylinders that are laterally connected to the hoppers; a right-handed spiral propulsion blade is installed inside the left cylinder, and a right-handed spiral propulsion blade is installed inside the right cylinder. Equipped with left-handed spiral propulsion blades, the fertilizer granule container has channels at the bottom that connect to the two cylindrical sections on either side. Conveying pipes are fixed to the bottom of both hoppers, and the discharge ends of these pipes are fixed to the back of the trenching shovels on either side. The backfilling device includes a pair of opposing support plates fixed to the base frame. Covering plates are fixed to the bottom of both support plates, each consisting of two flat plates arranged in a conical shape with a larger outer end and a smaller inner end. Drive wheels are rotatably connected to both sides of the base frame. A transmission system is installed on the base frame to synchronously drive the drive wheels and the right-handed and left-handed spiral propulsion blades. Handles are installed on both sides of the base frame. The function of the soil-shoveling and uniformly metering fertilizer application device here is to dig trenches in the soil, and then apply fertilizer evenly and quantitatively while the equipment is moving. The function of the soil return device is to backfill the excavated soil into the trenches, preventing fertilizer particles from being trapped in the air and losing their fertility, and also preventing soil erosion. The function of the transmission system is to provide power for the movement of the equipment and the dropping of fertilizer particles. The function of the handle is to provide support and steering for the equipment. The working principle of the soil-shoveling and uniformly metering fertilizer application device is as follows: the trenching shovel is embedded in the soil layer, and the drive wheel drives the equipment to move, so that the trenching shovel can dig trenches in the soil layer. At this time, the fertilizer particles in the fertilizer particle collection box fall into the cylinder through the channel. Because the right-hand and left-hand spiral propulsion blades rotate in opposite directions, the right-hand... When the left-hand and right-hand spiral propulsion blades rotate in the same direction, the fertilizer particles in the left cylinder are pushed into the left hopper, while the fertilizer particles in the right cylinder are pushed into the right hopper. Finally, they all fall through the conveying pipes to the back of the two trenching shovels. The right-hand and left-hand spiral propulsion blades have a spiral pushing function, achieving a uniform and quantitative distribution of fertilizer particles. The working principle of the soil return device is as follows: the soil return device has two flat plates with a larger outer opening and a smaller inner opening. The soil on both sides of the trench can be continuously pushed back into the trench by the two flat plates to return the fertilized trench. This uniform and quantitative fertilization equipment for tea plants uses a method of passing through the tea tree in the middle, opening trenches on both sides of the tea tree, and uniformly and quantitatively applying fertilizer to the tea tree.

[0010] Further improvements include a sprinkler system installed on the base frame. This system includes a water tank fixed to the frame, umbrella-shaped nozzles fixed to the frame behind each of the two soil-covering boards, and a suction pipe fixed to the water tank. Connecting pipes connect the two umbrella-shaped nozzles to the suction pipes, and a water pump is installed on the suction pipes. The purpose of this sprinkler system is to spray water onto the fertilizer granules buried in the soil, ensuring partial dissolution and allowing the tea trees to absorb the nutrients. This prevents fertilizer granules from remaining undissolved in dry soil for extended periods, which could hinder nutrient absorption by the tea trees and cause soil compaction. This combination of fertilization and watering significantly improves fertilizer utilization, enabling the tea trees to quickly obtain nutrients and grow vigorously.

[0011] Further improvements were made to the transmission system, which includes a first rotating shaft rotatably connected to the base frame. Two hoppers, two cylinders, two right-handed spiral propulsion blades, and two conveying pipes are located on the bottom left side of the fertilizer granule container. The discharge ends of the two left-hand conveying pipes are located at the back of the left-hand trenching shovel. Two hoppers, two cylinders, two left-handed spiral propulsion blades, and two conveying pipes are located on the bottom right side of the fertilizer granule container. The discharge ends of the two right-hand conveying pipes are located at the back of the right-hand trenching shovel. A pair of opposing second rotating shafts are rotatably connected to the support frame, driving the right-handed and left-handed spiral propulsion blades to rotate synchronously. First sprockets are mounted on both drive wheels, and a pair of opposing second sprockets are mounted on the first rotating shaft. A second sprocket is installed between each of the two first sprockets and the two second sprockets. A chain has two second shafts, each with a third sprocket mounted on it. A third chain is installed between the two third sprockets. A fourth sprocket is mounted on the second shaft. A fifth sprocket is mounted on the first shaft. A fourth chain is installed between the fourth and fifth sprockets. A reducer is fixed on each of the two support plates. A drive motor is fixed to the top of each reducer. The shafts of the two drive motors are fixed together with the input shafts of the two reducers. A sixth sprocket is fixed to the output shafts of the two reducers. A pair of opposing seventh sprockets are mounted on the first shaft. A fifth chain is installed between the two sixth sprockets and the two seventh sprockets. The function of the transmission system here is to coordinate the operation of the equipment, the movement of the drive wheels, and the falling of fertilizer granules, thereby ensuring uniform and quantitative application of fertilizer granules. The working principle of the transmission system is as follows: starting the drive motor, the reducer provides strong torque, which in turn rotates the sixth sprocket, driving the fifth chain, which in turn drives the seventh sprocket, which in turn drives the first shaft. The rotation of the first shaft synchronously drives the second sprocket, which in turn drives the first chain, which in turn drives the first sprocket, causing the drive wheels on both sides to rotate synchronously to move the equipment. Simultaneously, the rotation of the first shaft synchronously drives the fifth sprocket, which in turn drives the second shaft via the fourth chain. The second shafts on both sides, driven by the third chain, rotate synchronously, driving the right-hand and left-hand spiral propulsion blades within the four cylinders to rotate and uniformly and quantitatively feed fertilizer granules. The purpose of having two cylinders and two right-hand spiral propulsion blades on the left side, and two cylinders and two left-hand spiral propulsion blades on the right side, is to ensure smoother and more uniform fertilizer granule falling, as the spiral propulsion blades have the characteristic of equal-quantity feeding.

[0012] Further improvements include rear wheel compaction support assemblies on both sides of the rear end of the base frame. Each rear wheel compaction support assembly includes a swing arm hinged to the base frame, with a pressure roller rotatably connected to the end of the swing arm. A rod is fixed to the swing arm and inserted into the base frame, with a nut threaded onto the rod to secure it to the base frame. The function of these rear wheel compaction support assemblies is to provide rear-end support for the entire equipment, reducing the force required by the user during operation and lowering their workload. Furthermore, the pressure roller compacts the backfill soil, preventing soil erosion during rain due to loose soil.

[0013] To further improve the design, a vibrator is installed on top of the fertilizer granule container. The vibrator's function is to vibrate the container, causing the fertilizer granules to fall according to a regular vibration pattern, preventing them from accumulating and getting stuck. The vibrator is a commercially available product; options include those from Foshan Yunque Vibrator Co., Ltd., and Henan Gongwei Machinery Equipment Co., Ltd.

[0014] Further improvements include a conical guide plate at the bottom of the fertilizer granule container, wider at the top and narrower at the bottom. The guide plate has four through holes, each corresponding to one of the four channels. The purpose of the conical guide plate and through holes is to ensure that all fertilizer granules in the container are completely discharged. This prevents granules from remaining on the flat bottom surface, where prolonged retention can cause them to absorb water and soften, adhering to the container and contaminating the fertilizer granule transport process, as well as contaminating new batches and hindering stable granule delivery.

[0015] Further improvements include the addition of a self-lubricating layer on the inner contour surfaces of the four cylinders. This self-lubricating layer ensures that the outer contours of the right-hand and left-hand spiral propulsion blades fit tightly against the inner contour surfaces of the cylinders during operation. This prevents fertilizer granules from getting stuck in gaps between the blades and the cylinders, ensuring stable and precise delivery. Furthermore, the self-lubricating layer reduces frictional resistance and noise during operation of the right-hand and left-hand spiral propulsion blades. This self-lubricating layer is made of tin bronze.

[0016] Further improvements include a drive wheel comprising a circular frame, with a set of horizontal blocks evenly distributed around the center of the frame fixed on its outer contour surface. The function of the circular frame and horizontal blocks is to greatly increase the equipment's grip, preventing the drive wheel from slipping during operation. They also ensure that the speed of the drive wheel is proportional to the amount of fertilizer granules falling, allowing the equipment to apply fertilizer while moving, thus achieving uniform and quantitative fertilizer application.

[0017] Further improvements include a hinged cover plate at the top of the fertilizer granule container; and alloy heads installed at the ends of both trenching shovels. The cover plate serves to shield the fertilizer granules, preventing debris such as leaves and twigs from falling into the container and affecting the efficient, quantitative propulsion of the right-hand and left-hand spiral propulsion blades, thus preventing jamming. The alloy heads provide exceptional hardness to the trenching shovel heads, allowing them to easily push aside stones in the soil without deformation. This enables the equipment to operate in environments with poor soil conditions and abundant debris. The alloy heads are made of tungsten carbide.

[0018] Further improvements include a rechargeable lithium battery fixed to the top of the cover plate, a left-turn button switch on the left handle, a right-turn button switch on the right handle, and a speed control knob on the right handle. The rechargeable lithium battery is connected to the drive motor, water pump, left-turn button switches, right-turn button switches, and speed control knob via wiring. The rechargeable lithium battery powers the drive motor and water pump, allowing the equipment to move without being limited by the power cord, thus broadening its application scenarios. The left-turn button rotates the right drive wheel, facilitating left-turn adjustments; the right-turn button rotates the left drive wheel, facilitating right-turn adjustments; and the speed control knob controls the synchronous speed of the two drive wheels, allowing for easy speed adjustment.

[0019] The beneficial effects of this invention are:

[0020] 1) The soil-shoveling and uniformly metered fertilizer application device can dig trenches in the soil, and then the equipment moves while uniformly and quantitatively applying fertilizer;

[0021] 2) The backfilling device can backfill the excavated soil into the trench, preventing fertilizer particles from being trapped in the air and thus causing fertilizer loss, and also preventing soil erosion.

[0022] 3) The transmission system enables coordinated operation between the movement of the drive wheels and the falling of fertilizer granules during equipment operation, thereby ensuring uniform and quantitative application of fertilizer granules;

[0023] 4) The rear wheel compaction support assembly can provide rear-end support for the entire equipment, which can reduce the support force required by the user when operating the equipment, reduce the user's labor intensity, and the pressure roller can compact the backfill soil to prevent soil erosion caused by rain due to loose soil.

[0024] 5) The alloy head makes the trenching shovel's head very hard. When encountering stones in the soil, the alloy head can easily push the stones aside without deforming the trenching shovel's head. Thus, the alloy head allows the equipment to operate in environments with poor soil quality and many stones. Attached Figure Description

[0041] Both sides of the rear end of the base frame 1 are provided with rear wheel compaction support assemblies 8; the rear wheel compaction support assembly 8 includes a swing arm 8-1 hinged to the base frame 1, a pressure roller 8-2 rotatably connected to the tail end of the swing arm 8-1, an insertion rod 8-3 fixed on the swing arm 8-1 and inserted into the base frame 1, and a nut 8-4 threadedly connected to the insertion rod 8-3 to fasten the insertion rod 8-3 to the base frame 1.

[0042] A vibrator 9 is installed on the top of the fertilizer granule container 2-4.

[0043] The bottom of the fertilizer granule container 2-4 is equipped with a conical guide plate 2-4b with a larger opening at the top and a smaller opening at the bottom. The conical guide plate 2-4b has four through holes 2-4c that are respectively paired with the four channels 2-4a.

[0044] A self-lubricating layer 2-6a is provided on the inner contour surface of the four cylinders 2-6.

[0045] The drive wheel 4 includes a circular frame 4-1, and a set of transverse blocks 4-1a are evenly distributed in the center of the circular frame 4-1 and fixed on the outer contour surface of the circular frame 4-1.

[0046] The top of the fertilizer granule container 2-3 is hinged with a cover plate 10; the head ends of the two trenching shovels 2-2 are each equipped with an alloy head 2-2a.

[0047] A rechargeable lithium battery 11 is fixed on the top of the cover plate 10. A left turn button switch 12 is installed on the left handle 6, a right turn button switch 13 is installed on the right handle 6, and a speed control knob 14 is installed on the right handle 6. The rechargeable lithium battery 11 is connected to the drive motor 5-11, the water pump 7-5, the left turn button switch 12, the right turn button switch 13, and the speed control knob 14.

[0048] The working principle of this invention: Rotating the speed control knob 14 (to control the equipment's movement speed according to the user's working conditions; the faster the movement speed, the more fertilizer granules will fall synchronously), starts the drive motors 5-11 on both sides, thereby using the reducer 5-10 to provide strong torque, which in turn rotates the sixth sprocket 5-12, driving the fifth chain 5-14 to rotate, which in turn drives the seventh sprocket 5-13 to rotate, which in turn drives the first shaft 5-1 to rotate. The rotation of the first shaft 5-1 synchronously drives the second sprockets 5-3 on both sides to rotate, which in turn drives the first chain 5-4 to rotate, which in turn drives the first sprocket 5-2 to rotate, thus causing the drive wheels 4 on both sides to rotate synchronously to move the equipment. At the same time, the rotation of the first shaft 5-2 synchronously drives the fifth sprocket 5-8 to rotate, which in turn drives the second shaft 5-15 on one side to rotate via the fourth chain 5-9. The second shafts 5-15 on both sides are driven by the third chain 5-6, causing the two second shafts 5-15 to rotate synchronously, thereby synchronously driving the four cylinders 2-6 inside. The right-hand spiral propulsion blades 2-7 and 2-8 rotate, causing the fertilizer granules in the fertilizer granule container 2-4 to fall through the channel 2-4a into the cylinder 2-6. Because the right-hand spiral propulsion blades 2-7 and 2-8 rotate in opposite directions, when they rotate in the same direction, the fertilizer granules in the two left cylinders 2-6 are pushed into the two left hoppers 2-5, while the fertilizer granules in the two right cylinders 2-6 are pushed into the left hoppers 2-5. The fertilizer particles are pushed into the two lower hoppers 2-5 on the right side, and then fall through the conveying pipes 2-5a to the back of the two trenching shovels 2-2. During the movement of the equipment, the soil covering plates 3-2 on both sides will backfill the excavated soil into the trench, burying the fertilizer particles. At the same time, the water pump 7-5 is started, and water is pumped through the liquid extraction pipe 7-3 and transported through the connecting pipe 7-4. The water is then sprayed onto the backfilled soil through the umbrella-shaped nozzles 7-2 on both sides. Finally, the backfilled soil is pressed down once by the pressure roller 8-2 (e.g., ...). Figure 10 As shown in the figure, this device avoids soil erosion, enabling it to move, operate, fertilize, backfill, spray, and compact simultaneously. The process is automated, highly efficient, and produces uniform and quantitative fertilization with good results, making it worthy of widespread application.

[0049] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art will understand that various changes in form and detail are possible within the scope of the claims.
