Description

Technical Field

[0001] This invention relates to a device, particularly a fertilization device, and especially a multi-purpose tea fertilizer applicator. Background Technology

[0002] As an important economic crop, the quality and yield of tea leaves directly determine the economic benefits for growers. During the growth cycle of tea trees and the processing of tea leaves, a sufficient and balanced supply of nutrients is the core foundation for ensuring high-quality and high-yield tea. Therefore, scientific and efficient fertilization has always been a top priority in tea garden management.

[0003] Traditional tea tree fertilization methods rely heavily on experience and generally have the following problems: 1) Extensive fertilization methods and low fertilizer utilization: Currently, most tea gardens still use manual or simple mechanical application methods to apply fertilizer directly to the soil surface. This method easily leads to the loss of fertilizer, especially soluble nutrients such as nitrogen and potassium, due to volatilization, leaching, and surface runoff. Studies have shown that the utilization rate of nitrogen fertilizer in the current season is usually only 30%-40%, which not only causes huge waste of resources and increased production costs, but also leads to serious non-point source pollution, threatening the surrounding water bodies and ecological environment. 2) Neglecting root zone fertilization and soil health: The absorbing roots of tea trees are mainly located in specific soil layers. Traditional surface-spread fertilizers are difficult for the roots to absorb effectively, and long-term shallow application will cause the roots to rise to the surface, reducing the tea tree's drought and cold resistance. In addition, long-term excessive application of chemical fertilizers will aggravate soil acidification and compaction, destroy the soil aggregate structure, inhibit the activity of soil microbial communities, thereby deteriorating the rhizosphere environment for tea tree growth and forming a vicious cycle of "the more fertilizer, the worse the soil". 3) High labor costs and low operational efficiency: Manual fertilization is labor-intensive and inefficient, and it is difficult to ensure the uniformity of fertilization, which cannot meet the management needs of modern large-scale tea gardens.

[0004] Chinese utility model patent CN 208638975 U discloses a tea tree fertilization device. The device includes a frame with casters at the bottom and a fertilizer tank on the frame. The fertilizer tank has a feed inlet at its top and two oppositely rotating conveyor screws inside, connected to a motor via belt drive. Two discharge ports are located on the front side wall of the fertilizer tank, connected to the two conveyor screws. Each discharge port has a control valve and a guide tube connected to it. A telescopic tube connects to the guide tube and then to a bendable discharge pipe. The device also includes a push rod connected to the frame. This device can only perform shallow surface fertilization, leading to significant fertilizer loss and deteriorating the rhizosphere environment for tea tree growth. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the prior art by providing a multi-purpose tea fertilizer applicator that can loosen the soil and apply fertilizer in equal proportions, thereby meeting the needs of high fertilization efficiency, uniform nutrient absorption, and good growth of tea trees.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: This multi-purpose tea fertilizer applicator includes a base, a soil loosening device at the front end of the base, a fertilizer applicator located at the rear end of the soil loosening device on the base, and a soil covering device located at the rear end of the fertilizer applicator on the base. The soil loosening device includes a support block longitudinally slidably connected to the base, a first rotating shaft rotatably connected to the support block, and a set of evenly spaced soil loosening rollers fixed on the first rotating shaft. An electric cylinder for driving the support block to move up and down is fixed on the base. The fertilizer applicator includes a set of vertical rods, each with a trenching shovel fixed to its bottom end. The head of each trenching shovel is pointed and curved downwards. A container for loading fertilizer granules is installed on the base, and a hopper corresponding to the number and position of the trenching shovels is provided at the bottom of the container. The device has a set of through holes that connect to each hopper. Each hopper has a rotating shaft installed inside, and each rotating shaft has a set of actuating blades evenly distributed along the center of the rotating shaft. The inner wall of each hopper has an arc surface that matches the outer contour of the actuating blades. Each hopper has a conveying pipe fixed to its bottom, and the discharge end of each conveying pipe is fixed to the back of each trenching shovel. The soil covering device includes inclined rods fixed to each vertical rod. Each inclined rod has a soil covering disc fixed to the bottom of it, located behind the trenching shovel. Each soil covering disc consists of two circular plates, which are arranged in a conical shape with a larger outer end and a smaller inner end. Front driving wheels are rotatably connected to both sides of the base. A transmission system is installed on the base to synchronously drive the first rotating shaft, the rotating shaft, and the front driving wheels to rotate. Handles are installed on both sides of the base.The function of the soil loosening device here is to loosen the soil, which is beneficial for the respiration of tea tree roots and the absorption of nutrients. The function of the fertilization device here is to dig trenches in the loosened soil, and then apply fertilizer evenly and quantitatively while the machine is moving. The function of the soil covering device here is to backfill the shoveled soil into the trenches, so as to prevent fertilizer particles from being trapped in the air and losing their fertility, and to prevent soil erosion. The function of the transmission system here is to enable the front drive wheel, the soil loosening roller, and the actuating blades to move synchronously, so that the machine can coordinate a series of operations such as moving forward, loosening soil, digging trenches, fertilizing, and backfilling. The function of the electric cylinder here is to drive the soil loosening roller to move downward and loosen the soil when the machine is running, and to drive the soil loosening roller to move upward when the machine moves to another location, so as to prevent the soil loosening roller from hitting hardened ground. The working principle of the soil loosening device here is: the first rotating shaft rotates at high speed, thereby driving each soil loosening roller to rotate at high speed. The machine rotates, and then the electric cylinder drives the support block to move down, thereby loosening the soil layer, which is beneficial to the respiration of the tea tree roots and the absorption of nutrients. The working principle of the fertilization device is as follows: the trenching shovel is embedded in the soil layer, and the front driving wheel drives the machine to move, so that the trenching shovel can dig trenches in the soil layer. At this time, the fertilizer granules in the holding box fall into the feeding hopper through the through hole. Then, each rotating shaft is driven to rotate through the fifth rotating shaft, so that each blade rotates and conveys the fertilizer in equal portions. The fertilizer is then discharged from the conveying pipe and falls onto the back of the trenching shovel. The working principle of the soil covering device is as follows: the soil covering device has two circular plates with larger outer ends and smaller inner ends. Soil on both sides of the trench can be pushed back into the trench by the two circular plates to back the soil in the fertilized trench. The handle is used to support the machine and control the direction. This multi-purpose tea fertilizer uses multiple parallel trenches to dig between two rows of tea trees and apply fertilizer evenly and quantitatively.

[0007] Further improvements include a pruning device mounted on the base. This device comprises a bracket fixed to the base, with a second rotating shaft rotatably connected to the bracket. On both sides of the second rotating shaft are third rotating shafts, angled to the second shaft and rotatably connected to the bracket. Universal joints are installed between the two second and three rotating shafts. Cutting saw blades are fixed to the outer ends of the two second rotating shafts, arranged in a figure-eight configuration. A transmission system synchronously drives the second rotating shafts to rotate at high speed. The function of this pruning device is to prune the sides of the tea bushes, preventing them from being squeezed between rows of tea bushes and hindering movement. Pruning the sides also promotes the growth of the tea bush tips, thus benefiting the overall growth of the tea bushes. The figure-eight configuration of the two cutting saw blades allows for downward slant pruning, preventing the tips from being cut and promoting healthy growth. The universal joints allow the force transmitted by the second rotating shafts to be transferred to the third rotating shafts, thereby driving the cutting saw blades to rotate.

[0008] Further improvements include a rear-wheel drive device at the rear end of the base; the rear-wheel drive device includes a set of rear wheel assemblies evenly distributed along the width of the base; the rear wheel assembly includes a wheel frame hinged to the base, a rear driving wheel mounted on the wheel frame, a first block hinged to the base, a second block rotatably connected to the wheel frame, a threaded rod fixed to the second block, the threaded rod inserted into the first block, a compression spring sleeved on the threaded rod between the bottom surface of the first block and the second block, and an adjusting nut threadedly connected to the threaded rod; each rear driving wheel is synchronously driven to rotate through a transmission system. The function of the rear-wheel drive unit here is to provide directional support to the rear of the machine, making the machine more stable and providing more precise guidance during operation. The function of the first block, the second block, the threaded rod, and the compression spring is to make the rear of the machine move elastically, reducing vibration and improving stability. When the soil is hard and the trenching head cannot dig a deep trench, the rear-wheel drive unit can be pressed down to allow the trenching head to poke downwards, thus enabling smooth and efficient trenching. The function of the adjusting nut here is to adjust the angle of the rear moving wheel, thereby adapting to different terrains, especially on slightly sloping terrain, to prevent the device from tipping down or tilting up.

[0009] Further improvements include a transmission system comprising a set of reducers fixed to a base, with a drive motor fixed to the top of each reducer. The shaft of each drive motor is coupled to the input shaft of each reducer. A first sprocket is mounted on the output shaft of each reducer. A fourth shaft is rotatably connected to the base, and a set of second sprockets is mounted on the fourth shaft. A first chain is installed between each first sprocket and each second sprocket. A third sprocket is mounted on the fourth shaft. A fourth sprocket is mounted on the shaft of each rear driving wheel, and a second chain is installed between each third sprocket and each fourth sprocket. A fifth shaft is rotatably connected to the base, synchronously driving the rotation of each shaft. A fifth sprocket is mounted on the fifth shaft. A sixth sprocket is mounted on the fourth shaft, and a third chain is installed between each fifth sprocket and each sixth sprocket. A seventh sprocket is mounted on the shaft of each of the two front driving wheels. A seventh sprocket is mounted on the shaft of the fifth shaft. The device is equipped with a pair of opposing eighth sprockets. A fourth chain is installed between each of the two seventh and eighth sprockets. A set of ninth sprockets is mounted on the second shaft, and a set of tenth sprockets is mounted on the fifth shaft. A fifth chain is installed between each ninth and tenth sprocket. The number of teeth on the tenth sprockets is greater than that on the ninth sprockets. A sixth shaft is rotatably connected to the support block, and an eleventh sprocket is mounted on the sixth shaft. A twelfth sprocket is mounted on the first shaft, and a sixth chain is installed between the eleventh and twelfth sprockets. A first bevel gear is fixed to the sixth shaft. A splined shaft is rotatably connected to the support block, and a second bevel gear meshing with the first bevel gear is fixed to the bottom end of the splined shaft. A cage is fixed to the base, and a splined sleeve that inserts into the splined shaft is rotatably connected to the cage. A third bevel gear is fixed to the second shaft, and a fourth bevel gear meshing with the third bevel gear is fixed to the splined sleeve.The function of the transmission system here is to coordinate the rotation of the front and rear driving wheels with the falling fertilizer granules during machine operation, and to simultaneously operate the loosening roller and cutting saw blade. This not only loosens the soil and applies fertilizer quantitatively and evenly, but also allows for simultaneous pruning of both sides of the tea trees. The working principle of the transmission system is as follows: Starting the drive motor drives the reducer to provide strong torque and rotate the first sprocket. The rotation of the first sprocket, through the transmission of force from the first chain, causes the second sprocket to rotate, which in turn drives the fourth shaft. The rotation of the fourth shaft simultaneously drives the third and sixth sprockets, which, through the transmission of force from the second and third chains, cause the fourth and fifth sprockets to rotate. This, in turn, simultaneously drives the rear driving wheel and the fifth shaft. The rotation of the fifth shaft simultaneously drives the eighth and tenth sprockets, which, through the transmission of force from the fourth and fifth chains, cause the seventh and ninth sprockets to rotate. This, in turn, simultaneously drives the front driving wheel and the second shaft to rotate, and starts the high-speed rotation of the cutting saw blade. The rotation of the second shaft... The system synchronously drives the third bevel gear to rotate, which in turn drives the fourth bevel gear, which in turn drives the spline sleeve to rotate. The spline sleeve then drives the spline shaft to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear then drives the first bevel gear to rotate, which in turn synchronously drives the sixth shaft to rotate, which in turn drives the eleventh sprocket to rotate. The rotation of the eleventh sprocket, through the force transmission of the sixth chain, causes the twelfth sprocket to rotate, which in turn drives the first shaft to rotate, which in turn synchronously drives each loosening roller to rotate at high speed, thus performing a synchronous soil loosening operation. The reason why the tenth sprocket has more teeth than the ninth sprocket is that it can increase the speed of the second shaft, thereby increasing the speed of the cutting saw blade and the loosening roller, improving the cutting effect on the side of the tea tree and the soil loosening effect. The function of the spline shaft and spline sleeve is to ensure that the rotation of the loosening roller is not affected when it moves up and down, that is, the loosening roller can move up and down while rotating. The front and rear driving wheels can roll, thus achieving four-wheel drive operation of the machine, which not only avoids slippage but also makes the movement more stable.

[0010] Further improvements include the installation of a vibrator on the material container; a conical plate with a wider top and narrower bottom is installed at the bottom of the container, with a set of discharge holes corresponding to the various through holes. The vibrator's function is to vibrate the container, causing the fertilizer granules inside to vibrate and fall regularly, 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. The conical plate and discharge holes ensure that all fertilizer granules are completely discharged from the container, preventing some granules from remaining on the flat bottom surface. This prevents granules from absorbing water, softening, and adhering to the container, which would contaminate the fertilizer granule transport and the next batch, hindering stable fertilizer granule transport.

[0011] Further improvements include the addition of protective covers at the sides of both cutting saw blades, fixed to the material container. These covers serve a safety function, preventing accidental injury to operators.

[0012] As a further improvement, a cover plate is hinged to the top of the material container. The purpose of this cover plate is to prevent branches and dead leaves from falling into the material container, thereby affecting the even distribution of fertilizer granules.

[0013] Further improvements include a self-lubricating layer on the inner wall of the hopper. This self-lubricating layer ensures that the agitator blades adhere to the inner wall of the hopper, preventing fertilizer particles from getting stuck in the gap between the inner wall and the outer contour of the agitator blades. This allows the agitator blades to rotate more smoothly, preventing jamming and making the movement of the fertilizer particles smoother. This self-lubricating layer is made of tin bronze.

[0014] Further improvements include the addition of an alloy cover to the head of each trenching shovel. The purpose of this alloy cover is to make the trenching shovel head extremely hard. When encountering stones in the soil, the alloy cover can easily push the stones aside without deforming the shovel head. This allows the machine to operate in environments with poor soil conditions and many stones. The alloy cover is made of tungsten carbide.

[0015] Further improvements include a rechargeable lithium battery fixed to the material container, and a power switch, speed control knob, and lifting switch mounted on the handle. The rechargeable lithium battery is connected to the drive motor, electric cylinder, power switch, speed control knob, and lifting switch via wiring. The rechargeable lithium battery provides power to the drive motor and electric cylinder, allowing the machine's movement distance to be unrestricted by the power cord, thus broadening its application scenarios. The power switch controls the on / off operation of the drive motor and electric cylinder. The speed control knob regulates the synchronous speed of the front and rear moving wheels, allowing for convenient speed adjustment. The lifting switch controls the up / down movement of the support block, thereby adjusting the up / down movement of the loosening roller.

[0016] The beneficial effects of this invention are: 1) The soil loosening device can loosen the soil, which is beneficial for the respiration of tea tree roots and the absorption of nutrients; 2) The fertilization device here can shovel trenches into the loosened soil layer, and then the machine moves while applying fertilizer evenly and quantitatively; 3) The soil covering device can backfill the excavated soil into the trench, preventing fertilizer particles from being trapped in the air and thus avoiding fertilizer loss and soil erosion. 4) The transmission system enables the machine to operate in coordination with the rotation of the front and rear moving wheels and the falling of fertilizer particles, and can simultaneously perform soil loosening roller and cutting saw blade, thus not only loosening the soil and applying fertilizer quantitatively and evenly, but also pruning the tea trees on both sides at the same time.

[0017] 5) The vibrator can vibrate the container, causing the fertilizer granules inside to vibrate regularly and fall, avoiding the problem of them piling up and getting stuck. Attached Figure Description

The rotation of the first sprocket 6-3 will transmit force through the first chain 6-6 and cause the second sprocket 6-5 to rotate, thereby driving the fourth shaft 6-4 to rotate. The rotation of the fourth shaft 6-4 will synchronously drive the third sprocket 6-7 and the sixth sprocket 6-8. The rotation of sprocket 12, through the transmission of force via the second chain 6-9 and the third chain 6-13, causes the fourth sprocket 6-8 and the fifth sprocket 6-11 to rotate, thereby synchronously driving the rear drive wheel 9-1b and the fifth shaft 6-10 to rotate. When the fifth shaft 6-10 rotates, it synchronously drives the eighth sprocket 6-15 and the tenth sprocket 6-18 to rotate, thus, through the transmission of force via the fourth chain 6-16 and the fifth chain 6-19, causing the seventh sprocket 6-14 and the ninth sprocket 6-17 to rotate. The synchronous drive of the front drive wheel 5 and the second rotating shaft 8-2 causes them to rotate synchronously, and starts the high-speed rotation of the cutting saw blade 8-5. The rotation of the second rotating shaft 8-2 synchronously drives the third bevel gear 6-28 to rotate, which in turn drives the fourth bevel gear 6-29 to rotate, thereby driving the spline sleeve 6-27 to rotate. The spline sleeve 6-27 then drives the spline shaft 6-24 to rotate, which in turn drives the second bevel gear 6-25 to rotate, and the second bevel gear 6-25 then drives the first bevel gear 6-23 to rotate, thus... The sixth rotating shaft 6-30 is driven to rotate, which in turn drives the eleventh sprocket 6-20 to rotate. The rotation of the eleventh sprocket 6-20, through the force transmitted to the sixth chain 6-22, causes the twelfth sprocket 6-21 to rotate, thereby driving the first rotating shaft 2-2 to rotate. This, in turn, drives each loosening cutter 2-3 to rotate at high speed. Then, the lifting switch 17 (or control switch) is pressed quickly, which drives the support block 2-1 to move down through the electric cylinder 2-4, causing the loosening cutters 2-3 to contact the soil layer and loosen the soil (e.g., ...). Figure 10As shown), while the soil is being loosened, the trenching shovel 3-2 is embedded into the soil layer, and the machine moves synchronously, thus the trenching shovel 3-2 digs a trench in the soil layer. At this time, the fertilizer granules in the material box 3-3 fall into the feed hopper 3-4 through the discharge holes 3a-3b and the through hole 3-3a. At the same time, each rotating shaft 3-5 has been synchronously driven to rotate by the fifth rotating shaft 6-10, thus the blades 3-6 rotate and convey fertilizer granules in equal portions, which are then discharged through the conveying pipe 3-7 and fall into the trench dug by the trenching shovel 3-2. Subsequently, the soil on both sides of the trench is pushed back into the trench by the two circular plates 4-2a, and the fertilized trench is backfilled. During the movement of the machine, the cutting saw blades 8-5 on both sides rotate at high speed synchronously and prune the side ends of the tea trees on both sides (such as...). Figure 11 As shown in the figure, this invention can simultaneously loosen the soil, dig trenches, apply fertilizer in equal portions, backfill the soil, and prune the side ends of the tea trees. It not only has high fertilization efficiency and low tea tree planting costs, but also enables the tea trees to absorb fertilizer well and grow rapidly after pruning. It is worth promoting and applying.
