Description

Technical Field

[0001] The invention belongs to the technical field of planting and fertilization, and specifically relates to an intelligent fertilizer applicator for tea planting and production. Background Art

[0002] Tea planting mainly consists of three important links: fertilization, weeding and pruning. Among them, tea fertilization is divided into: base fertilizer: mainly carried out in winter or early spring to supplement soil nutrients; topdressing: carried out during the vigorous growth period of tea trees to supplement the nutrients needed for growth; foliar fertilizer: by spraying nutrients on the leaves, it can quickly supplement the nutrients needed for tea tree growth; and, according to the depth of fertilization, it is divided into: base fertilizer: applied to the soil, the depth is generally 15-20cm; topdressing: applied to the soil, the depth is generally 5-10cm.

[0003] In the process of large-scale fertilization of tea, the following problems will be encountered:

[0004] Manual fertilization requires digging, spreading fertilizer, and backfilling. The labor efficiency is low, resulting in a long fertilization cycle. If it rains during the rainy season, the fertilization cycle will be further extended, resulting in uneven growth of the same batch of tea leaves.

[0005] Excessive fertilization will cause poor growth or even death of tea trees; while too little fertilization will lead to an imbalance of nutrients, affecting the growth of tea trees and the quality of tea leaves;

[0006] Improper fertilization methods will lead to reduced fertilizer utilization and affect the growth of tea trees. For example, if the fertilization location is too close to the roots of the tea trees, the fertilizer will burn the roots of the tea trees. Moreover, if the fertilizer particles are too large, the fertilizer will be difficult to dissolve and will not be absorbed by the tea trees in time, causing poor growth of the tea trees and even diseases and pests.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] An intelligent fertilizer applicator for tea planting and production, as shown in the accompanying drawings of the specification Figure 1-Figure 11 As shown, the fertilizer vehicle 1 includes a fertilizer application vehicle 1 and a storage box 11, and the fertilizer application vehicle 1 moves in the tea garden by carrying fertilizer through the storage box 11; the fertilizer application vehicle 1 is a conventional human-controlled moving vehicle; and further includes:

[0041] A support frame 12 is installed on the fertilizer vehicle 1, and a storage box 11 is installed on the support frame 12. A camera 13 is provided on the fertilizer vehicle 1; a rotating shaft 14 is rotatably connected to one side of the support frame 12, and the rotating shaft 14 is connected to a motor 15 arranged in the support frame 12, and a rotating wheel 16 is provided at a position of the rotating shaft 14 away from the support frame 12; a spiral blade 17 is provided on the rotating shaft 14, and a sleeve 18 is provided on the support frame 12, and the spiral blade 17 is located between the rotating shaft 14 and the sleeve 18, and the sleeve 18 is connected to the storage box 11 through a pipeline; workers observe the image taken by the camera 13 through the screen on the fertilizer vehicle 1, that is, the part of the tea tree close to the root, which is convenient for workers to observe;

[0042] Conveyor belt 2, conveyor belt 2 is arranged above the rotating wheel 16, and conveyor belt 2 rotates in an arc track, and the rotating wheel 16 rotates by contacting the bottom of conveyor belt 2; baffles 21 are arranged on both sides of conveyor belt 2, and conveyor belt 2 is rotatably connected to baffles 21, and one end of conveyor belt 2 is provided with a shovel board 22; vibration blocks 23 are evenly arranged at the position of baffle 21 away from rotating wheel 16, and vibration blocks 23 contact depressions 24 arranged on the surface of conveyor belt 2, and depressions 24 are wavy; shovel board 22 is fixed to support frame 12 by hardware, and shovel board 22 can be adjusted in height to meet the requirements of different fertilization depths and improve the convenience of use; camera 13 is located on the side of baffle 21 close to the rhizome of tea tree, which is convenient for camera 13 to shoot at close range;

[0043] The fixed shaft 25 is arranged at one end of the conveyor belt 2 away from the scraper plate 22, and the fixed shaft 25 is rotatably connected with a covering plate 26 through a torsion spring; the covering plate 26 is T-shaped, and one end of the covering plate 26 contacts the depression 24, and the other end extends into the soil.

[0044] Specific work flow: When the worker pushes the fertilizer cart 1 close to the roots of the tea trees, the worker observes the rhizomes of the tea trees through the camera 13. On the one hand, the worker can conveniently understand the growth of the roots of the tea trees without bending over. On the other hand, the worker can freely control the distance between the fertilization position and the roots of the tea trees according to the captured images to avoid the fertilizer from corroding and damaging the roots of the tea trees due to the fertilization too close, thereby improving the fertilization effect and promoting the growth of the tea trees.

[0045] After determining the fertilization position or the fertilization path of the fertilizer spreading vehicle 1, the worker first adjusts the height position of the shovel board 22 according to the fertilization depth requirement, and then drives the fertilizer spreading vehicle 1 to move. The shovel board 22 shovels the soil according to the set depth, so that a gully is formed under the rotating wheel 16 and the sleeve 18, thereby achieving the purpose of ditching; the motor 15 drives the spiral blade 17 to rotate in the sleeve 18 through the rotating shaft 14, and the sleeve 18 is fixed. The fertilizer in the storage box 11 enters between the sleeve 18 and the rotating shaft 14 through the pipeline and is moved by the spiral blade 1 7 is transported to the top of the gully until the fertilizer is sprinkled in the gully; while fertilizing, the rotating shaft 14 drives the conveyor belt 2 to operate through the rotating wheel 16, and after the soil on the shovel plate 22 falls on the conveyor belt 2, the soil is transported to the soil cover plate 26 and falls as the conveyor belt 2 moves, completing the backfilling of the ditch after fertilization; through the above method, soil digging, fertilization and backfilling are integrated to improve the fertilization efficiency, thereby avoiding the extension of the fertilization cycle and the sudden rainy weather, resulting in inconsistent fertilization time for the same batch of tea trees, resulting in inconsistent growth conditions;

[0046] Moreover, the rotating shaft 14 is a common component between the conveyor belt 2 and the spiral blade 17. When the speed of the spiral blade 17 is increased, the speed of the fertilizer conveying and spreading is increased, and the speed of the soil shovel plate 22 and the conveyor belt 2 digging and backfilling is also increased. For example, if the fertilizer is spread quickly, the speed of digging and backfilling will increase together. If the fertilizer is spread slowly, the speed of digging and backfilling will also slow down accordingly, so as to avoid the situation that the speeds of the two are not uniform, resulting in excessive or insufficient fertilization, thereby improving the uniformity of fertilization, further promoting the uniformity of the growth of tea trees, and reducing the possibility of uneven quality of tea leaves after picking.

[0047] Moreover, during the conveyor belt 2 conveys soil, the conveyor belt 2 is restricted by the baffle 21, which can effectively block the soil and prevent it from falling from the edges of both sides of the conveyor belt 2, resulting in insufficient backfill and fertilizer exposure, thereby improving the backfill effect and thus improving the fertilization effect; if the soil is in the form of a large block, the backfill effect of the soil is poor, and it is easy to get stuck between the conveyor belt 2 and the cover plate 26 due to its large volume, affecting the subsequent backfill of the soil; therefore, when the depression 24 on the conveyor belt 2 passes through the vibrating block 23, the vibrating block 23 extends into the depression 24 The movement process of moving toward and away from the depression 24 causes the part of the conveyor belt 2 close to the vibration block 23 to rise suddenly, and is limited by the clamping effect of the vibration block 23 in the depression 24. After the conveyor belt 2 rises for a certain distance, it stops, and the soil on the conveyor belt 2 is lifted up and falls down, so as to achieve the purpose of breaking up large pieces of soil by vibration, reduce the volume of lumps in the soil, and improve the backfilling effect. Moreover, when the soil is lifted up, it will be blocked by the baffle 21 to prevent it from falling from both sides of the conveyor belt 2, so as to maintain the amount of soil transported and ensure that the amount of soil transported can well backfill the gully;

[0048] After the soil is backfilled, if the backfilled soil is too loose, it is easy to cause the soil to be washed away when it rains, resulting in the fertilizer being exposed or washed away together, and the loss of soil at the roots of the tea trees will also cause changes in the soil structure, resulting in the soil being unable to fix and support the tea trees, resulting in the collapse of the tea trees, etc.; therefore, when the depression 24 passes through the fixed axis 25, one end of the covering plate 26 extends into the depression 24 and moves between adjacent depressions 24, and is squeezed and rotated along the axis of the fixed axis 25, so that the other end of the covering plate 26 is lifted away from the soil; the covering plate 26 passes over the adjacent depressions 24 and extends into the depression 24 again, and the covering plate 26 is no longer squeezed and reversed to reset, and the other end of the covering plate 26 reverses and hits the backfilled soil, which improves the backfilling effect while reinforcing the soil structure after fertilization and excavation, thereby improving the fertilization effect.

[0049] Embodiment 2:

[0050] On the basis of the first embodiment, a feeding plate 3 is provided on one side of the sleeve 18 close to the rotating wheel 16, and a feeding port 31 is provided at the bottom of the feeding plate 3; a feeding column 32 is slidably connected to one side of the feeding plate 3 through a spring, two feeding columns 32 form a group, and the number is provided in multiple groups, and the feeding columns 32 slide into the feeding plate 3; the surface of the feeding column 32 is evenly provided with receiving grooves 33, and a crushing rod 34 is hinged in the receiving groove 33 through a torsion spring;

[0051] One end of the spiral blade 17 slides on the unloading plate 3, and the spiral blade 17 is evenly provided with a driving groove 35, the top of the unloading column 32 is located in the driving groove 35, the surface of the unloading column 32 contacts one of the inner walls on both sides of the driving groove 35, and a ball 36 is provided at the center of the top of the unloading column 32; the rotation direction of each group of unloading columns 32 is opposite; a water supply box 37 is provided in the fertilizer spreading vehicle 1, and the unloading plate 3 is provided with nozzles 38 on both sides of the unloading port 31, and the water supply box 37 and the nozzle 38 are connected by a pipe; the driving groove 35 contains three inner walls, two of which are the inner walls on the left and right sides, and one is the inner wall at the deep end; the water supply box 37 is a conventional water tank water supply device, which contains a water pump for supplying water to the nozzle 38 through a pipe;

[0052] The crushing rods 34 in each group of material discharge columns 32 are arranged in a staggered manner, and the crushing rod 34 in one material discharge column 32 is located in the middle of two crushing rods 34 in another material discharge column 32; the material discharge column 32 is provided with an extrusion bar 39 between adjacent crushing rods 34, and the surface of the extrusion bar 39 is serrated, and the extrusion bar 39 is away from the crushing rod 34.

[0053] Specific working process: During the fertilization process, if the fertilizer particles are large or form lumps due to placement or other reasons, the fertilizer needs to be broken up to reduce the particle size of the fertilizer, so as to achieve the effect of promoting the fertilizer to be absorbed by the roots and stems of the tea tree; therefore, the spiral blade 17 rotates, and the unloading plate 3 remains fixed, and when the spiral blade 17 approaches the unloading column 32, the unloading column 32 extends into the driving groove 35, and the ball 36 contacts the inner wall deep inside the driving groove 35, and the two adjacent unloading columns 32 contact the inner walls of the adjacent driving grooves 35 that are close to each other, that is, the first unloading column 32 contacts the right inner wall of the first driving groove 35, and the second unloading column 32 contacts the left inner wall of the second driving groove 35 The spiral blade 17 rotates, and the right inner wall drives the first feeding column 32 to rotate forward through friction, and the left inner wall drives the second feeding column 32 to rotate reversely, so that the two adjacent feeding columns 32 rotate in opposite directions; when the spiral blade 17 transports the fertilizer to the feeding port 31, the fertilizer contacts the two feeding columns 32 rotating in opposite directions, and the two feeding columns 32 rotating in opposite directions push the fertilizer to the middle of the two feeding columns 32 through the serrated extrusion strips 39, and then pass through after being squeezed and crushed, and then discharged from the feeding port 31 and dropped into the gully, thereby reducing the fertilizer particle size, promoting the tea tree to absorb the fertilizer, improving the fertilization effect, and thus improving the convenience of using the fertilizer spreader;

[0054] The feeding column 32 drives the crushing rod 34 to rotate. During the rotation of the crushing rod 34 on the adjacent feeding column 32, the fertilizer is continuously struck and stirred to further break up the fertilizer, reduce the particle size of the fertilizer, and promote the absorption of the fertilizer; and, the end of the spiral blade 17 that contacts the feeding plate 3 rotates close to the feeding column 32, and the feeding column 32 is squeezed by the driving groove 35, driving the crushing rod 34 to continuously retract into the feeding plate 3; the crushing rod 34 is squeezed by the feeding plate 3 and then swings in the receiving groove 33 until the crushing rod 34 swings into the receiving groove 33 to complete the storage, and the feeding column 32 is also retracted into the feeding plate 3, so that the spiral blade 17 can pass over the feeding column 32 while scraping the surface of the feeding plate 3 to avoid the residue and adhesion of the fertilizer, improve the cleaning degree, and avoid the residual invalid fertilizer to affect the fertilization effect of the tea tree;

[0055] Moreover, when the material discharge column 32 is retracted into the material discharge plate 3, the material discharge plate 3 scrapes and cleans the material discharge column 32, and the storage groove 33 scrapes and cleans the crushing rod 34, which further reduces the fertilizer residue and improves the convenience of cleaning the fertilizer spreader after use, thereby improving the practicality; when the material discharge column 32 moves along the driving groove 35, the left inner wall of the driving groove 35 drives the material discharge column 32 to rotate through friction, while the inner wall at the deep end squeezes the material discharge column 32 to retract into the material discharge plate 3, and the ball bearing 36 is provided to realize the material discharge column 32 slidingly retracting into the material discharge plate 3 while rotating, and can also reduce the friction between the top of the material discharge column 32 and the inner wall at the deep end of the driving groove 35, so as to prevent metal debris generated by excessive friction from mixing into the fertilizer and affecting the fertilization effect;

[0056] When the fertilizer falls from the discharge port 31, the water supply tank 37 supplies water to the nozzle 38. The nozzles 38 on both sides of the discharge port 31 spray water toward the gully while wetting the fertilizer to promote the absorption of the fertilizer. When the soil moisture is good and the fertilizer can be dissolved, the nozzle 38 can be closed. When it is too dry, spraying water helps the fertilizer to be used quickly and improves the fertilization effect. Moreover, if the fertilizer is scattered when it falls due to wind or other reasons, the water sprayed from the nozzles 38 on both sides of the discharge port 31 can block the fertilizer while wetting it to prevent it from scattering. Moreover, the weight of the fertilizer increases after being wetted, so it can fall into the ditch more quickly and be backfilled in time.

[0057] Embodiment three:

[0058] On the basis of the second embodiment, a top cover 4 is provided on the top of the scraping blade 22, and a transmission belt 41 is rotatably connected to the hollow interior of the scraping blade 22, the rotation track of the transmission belt 41 is a triangle, and the transmission belt 41 is connected to the conveyor belt 2 through a belt; a slide groove 42 is provided on the top of the scraping blade 22, and a slide frame 43 is slidably connected in the slide groove 42; a slide rod 44 is slidably connected to the center of the slide frame 43, one end of the slide rod 44 is rotatably connected to one side of the transmission belt 41, and the other end passes through the slide frame 43 and is located in the top cover 4;

[0059] A grille 45 is provided at one end of the top cover 4 close to the conveyor belt 2, and a telescopic plate 46 is rotatably connected to the shovel board 22, one end of the telescopic plate 46 is located at the bottom of the grille 45, and the other end is rotatably connected to the top of the slide bar 44; the telescopic plate 46 is a conventional plate with a telescopic function, for example, a small plate is slidably connected in a large hollow plate, so that the small plate can be telescoped in the large hollow plate;

[0060] A dustproof cloth 47 is rolled up at one end of the scraper plate 22 away from the grille 45, and one end of the dustproof cloth 47 is connected to the telescopic plate 46; a rubber strip 48 is provided on the dustproof cloth 47, and a clamping ring 49 is provided on the top of the sliding frame 43, and the clamping ring 49 is located on the side of the sliding rod 44 away from the grille 45, and the rubber strip 48 moves inside the clamping ring 49.

[0061] Specific working process: the conveyor belt 2 is driven by the belt drive transmission belt 41, and the transmission belt 41 drives the slide bar 44 to move. Since the slide bar 44 is set to slide up and down in the slide frame 43, when the transmission belt 41 drives the slide bar 44 to approach the conveyor belt 2 obliquely upward, the slide bar 44 remains in a vertical state, and the soil on the shovel plate 22 is pushed onto the conveyor belt 2, thereby improving the conveying effect of the soil and preventing the soil from being shoveled onto the conveyor belt 2 due to moisture, stickiness or excessive weight, thereby improving the soil backfilling efficiency and further improving the fertilization effect; After the soil is pushed onto the conveyor belt 2, the transmission belt 41 rotates. Since the transmission belt 41 and the slide bar 44 are slidably connected, and the movement trajectory of the transmission belt 41 is a right triangle, the transmission belt 41 first drives the slide bar 44 to descend in the slide frame 43, and the slide bar 44 gradually retracts into the soil-shoveling plate 22 to prevent the slide bar 44 from pushing the soil in the opposite direction or blocking the moving soil when returning to the soil-shoveling plate 22; after the slide bar 44 retracts into the soil-shoveling plate 22, the transmission belt 41 drives the slide bar 44 to return away from the conveyor belt 2, completing a soil-moving work cycle;

[0062] When the slide bar 44 moves close to the grille 45, the slide bar 44 rises and drives the telescopic plate 46 from a horizontal state to an inclined state, and the telescopic plate 46 begins to shrink, squeezing the soil between the slide bar 44 and the grille 45 to pass through the grille 45, and the grille 45 divides and crushes the large pieces of soil, reducing the volume of the soil fragments, facilitating subsequent crushing, improving the backfilling effect, and thus improving the fertilization effect; when the slide bar 44 returns after approaching the grille 45, the slide bar 44 descends, and the telescopic plate 46 continues to shrink until the slide bar 44 is reset away from the grille 45, and the telescopic plate 46 becomes an extended state, ready for the next squeezing and crushing of the soil;

[0063] Furthermore, when the slide bar 44 is pushing the soil, the shovel board 22 will continue to shovel the soil. Due to the provision of the dustproof cloth 47, the dustproof cloth 47 can block the space at the bottom of the slide groove 42 and the telescopic plate 46 to prevent soil from entering and hindering the reset and movement of the slide bar 44 and the telescopic plate 46, thereby improving the convenience of use; through the cooperation between the rubber strip 48 and the clamping ring 49, when the slide bar 44 rises and stretches the dustproof cloth 47, the dustproof cloth 47 drives the rubber strip 48 to continuously pass through the clamping ring 49, so that the dustproof cloth 47 is close to the shovel The top of the earth plate 22 and one side of the slide bar 44 move, increasing the volume of the soil contained in the earth shoveling plate 22 and the top cover 4, improving the soil moving efficiency and avoiding affecting the soil shoveling; moreover, the provision of the dustproof cloth 47 can also prevent the soil from adhering to the top of the earth shoveling plate 22 to form lumps. After the dustproof cloth 47 contacts the soil, the surface of the earth shoveling plate 22 scratches the dustproof cloth 47 during the retraction process, and the soil adhered to its surface is scraped off, thereby avoiding the soil sticking to the earth shoveling plate 22 and affecting the trenching and soil transporting work of the earth shoveling plate 22.

[0066] A limiting ring 54 is provided on one side of the baffle 21, and an opening is provided on the top of the limiting ring 54, and the inner ring of the conveyor belt 2 slides on the surface of the limiting ring 54; nozzles 55 are evenly provided on the support frame 12, and the nozzles 55 are tilted to point to the bottom of the conveyor belt 2 near the cover plate 26, and the nozzles 55 are connected to the water supply tank 37; the surface of the rotating wheel 16 contacts the depression 24, and the surface of the rotating wheel 16 is evenly provided with sliding plates 56, a spring is provided between the sliding plates 56 and the rotating wheel 16, and a sponge 57 is provided on the sliding plates 56; a guide plate 58 is provided on the sleeve 18, and the inclined surface of the guide plate 58 contacts the sliding plate 56;

[0067] A groove 6 is formed at a portion of the covering plate 26 near the depression 24; a scraper block 61 is slidably connected to one end of the covering plate 26 via a spring, and the scraper block 61 slides into the covering plate 26;

[0068] The bottom of the cover plate 26 is evenly hinged with a counterweight 62, and the counterweight 62 is conical.

[0069] Specific working process: when the vibration block 23 squeezes the conveyor belt 2 to descend, the conveyor belt 2 carries the squeezing rod 53 to contact the fixed plate 52 until the fixed plate 52 blocks the movement of the squeezing rod 53, and the conveyor belt 2 continues to approach the fixed plate 52, so that the squeezing rod 53 drives one end of the squeezing plate 51 to extend out of the sliding frame 5; the squeezing plates 51 on both sides of the recess 24 extend out to squeeze the soil fragments in the recess 24, and the soil is further crushed with the vibration to improve the soil backfilling effect, thereby improving the fertilization effect; and the soil is divided by the grid 45, and the squeezing plate 51 squeezes and the conveyor belt 2 vibrates to crush the soil fragments from large to small, thereby improving the soil crushing efficiency, and can also ensure that the soil is closely combined with each other after backfilling to bury the fertilizer, and can also avoid changes in the soil structure, resulting in unstable tea tree planting.

[0070] By setting the limiting ring 54, the conveyor belt 2 is not limited by the limiting ring 54 when contacting the vibration block 23; while the conveyor belt 2 is limited by the limiting ring 54 when contacting the rotating wheel 16, so as to avoid the situation that the conveyor belt 2 sometimes rotates and sometimes does not rotate due to insufficient friction generated by the contact between the conveyor belt 2 and the rotating wheel 16, thereby improving the conveying effect of the conveyor belt 2 on the soil; and if the conveyor belt 2 is driven by the driving device alone, the weight of the fertilizer spreader will be increased, resulting in inconvenience in its movement in the tea garden, affecting the fertilization efficiency;

[0071] Furthermore, when the depression 24 on the surface of the conveyor belt 2 is engaged with the surface of the runner 16, the driving ability of the runner 16 on the conveyor belt 2 can be increased, and the weight of the conveyor belt 2 carrying the transported soil can be increased, thereby meeting the requirements for the conveying weight and capacity of the conveyor belt 2 during rapid fertilization, and improving the practicality of the fertilizer spreader; when the conveyor belt 2 runs close to the nozzle 55, the water supply box 37 sprays water to the conveyor belt 2 through the nozzle 55 at one side edge of the conveyor belt 2, and the water flow flushes the surface of the conveyor belt 2 and the depression 24 to prevent the conveyor belt 2 from adhering to the soil and affecting the backfill; after the water flow is flushed, it falls on the tea tree with inertia, and while flushing and cleaning the conveyor belt 2, it can also water the tea tree, which is helpful for the tea tree to decompose and absorb the fertilizer; the water flows down along the tea tree to the rhizome, achieving a moistening effect, preventing the fertilizer from burning the roots, diluting the salt in the soil, and reducing the damage to the root system, thereby improving the fertilization effect;

[0072] After the conveyor belt 2 is flushed, the rotating wheel 16 drives the sponge 57 to contact the surface of the conveyor belt 2 and the depression 24 through the sliding piece 56. When the sliding piece 56 passes through the guide plate 58, it is guided by the inclined surface of the guide plate 58 and moves laterally on the rotating wheel 16. It moves and resets due to the influence of the spring reset, so that the sliding piece 56 can move back and forth laterally on the rotating wheel 16, and the sliding piece 56 drives the sponge 57 to reciprocate and wipe the surface of the conveyor belt 2 and the depression 24, thereby reducing the soil residue on the conveyor belt 2 and avoiding the soil from sticking to the conveyor belt 2, which affects the backfilling. The surface of the conveyor belt 2 can also be wiped dry by the sponge 57 to further prevent the soil from sticking.

[0073] By setting a scraper 61, the scraper 61 scrapes along the surface of the depression 24 to scrape off the soil adhered to it, thereby improving the cleanliness of the conveyor belt 2, facilitating subsequent flushing, and improving the cleaning effect; then the portion between the adjacent depressions 24 of the conveyor belt 2 contacts and squeezes one end of the covering plate 26, squeezing it up, and the covering plate 26 drives the counterweight 62 to rise and release the soil, and the soil on the conveyor belt 2 and the scraped soil fall into the gully through the groove 6, completing the backfilling work of burying the fertilizer; after the covering plate 26 passes over, it is reset, and the covering plate 26 slaps the backfilled soil to compact it, and penetrates into the soil through the conical counterweight 62, and a small conical groove is dug out in the backfilled soil, which is convenient for subsequent rainfall or watering to complete the water storage work; and the dug conical groove is close to the roots of the tea trees, which is more conducive to the tea trees absorbing water and improving the surrounding soil conditions.
