Description

Technical Field

[0001] This invention relates to the field of pruning machinery, and more particularly to a tea tree pruning machine. Background Technology

[0002] Tea tree pruning isn't about aesthetics. Spring pruning primarily aims to tidy up the canopy, rejuvenate the tree, and reduce canopy height, creating a suitable canopy height and a neat picking surface for easier harvesting and improved labor productivity. Secondly, tea tree pruning helps regulate the balance between the above-ground and underground parts of the tea tree, that is, the balance between branches, leaves, and roots. The above-ground and underground parts of the tea tree are an interdependent whole, maintaining a balance that is both contradictory and unified. Traditionally, tea tree pruning is usually done manually by hand or with a pruning machine on the back, sweeping horizontally. This method not only results in uneven sweeping of the tea tree top but is also labor-intensive. After a day's work, workers suffer from back pain and need to rest before continuing to work, reducing labor efficiency.

[0003] Chinese utility model patent CN 203340776 U discloses a tea tree pruning machine, which includes a gasoline engine, a transmission box, a left operating handle, blades, a guide plate, a right operating handle, and a right operating handle baffle. The exhaust port of the gasoline engine is equipped with a muffler, and the muffler is equipped with a replaceable exhaust gas purification device. The tea tree pruning machine is equipped with an adjustable shoulder strap. The left operating handle is fixedly connected to the transmission box through a shock absorber, and the left operating handle is equipped with a clutch handle and a control switch. This tea tree pruning machine uses a hand-held, sweeping method for pruning, which is labor-intensive, results in uneven pruning of the tea tree tops, and has low work efficiency, making it unsuitable for large-area, high-efficiency pruning of tea trees. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art by providing a tea tree pruning machine that is highly efficient in pruning the top of tea trees, prunes neatly, and sprays nutrient solution onto the pruning area immediately after pruning to promote better tea growth. This machine meets the needs of simultaneous tea pruning and nutrient spraying for better tea growth.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: This tea tree pruning machine includes a support, a trolley handle fixed on the support, rotating shafts rotatably connected to both ends of the support, wheels mounted on both rotating shafts, and first chain gears mounted on both rotating shafts. A pair of symmetrically arranged drive motors are fixed to the top of the support, and second chain gears are fixed to the rotation speeds of both drive motors. A first chain is installed between the first chain gears and the second chain gears. A pruning mechanism is installed at the head end of the support, and a spraying mechanism mounted on the support is provided between the pruning mechanism and the trolley handle. The pruning mechanism includes a vertical mounting frame fixed to the support, and three horizontally evenly arranged first, second, and third rotating shafts rotatably connected to the vertical mounting frame. Cutting blades are provided at the bottom ends of the first, second, and third rotating shafts. A first pulley and a second pulley are fixed on the first rotating shaft, arranged vertically and horizontally. A third and fourth pulley are fixed on the shaft, one above the other. A fifth pulley is fixed on the third shaft. A high-speed spindle motor is fixed on the support. A sixth pulley is fixed on the shaft of the high-speed spindle motor. A first belt is installed between the sixth pulley and the first pulley. A second belt is installed between the second pulley and the fourth pulley. A third belt is installed between the third pulley and the fifth pulley. The spraying mechanism includes a crossbeam fixed on the support. A vertical main pipe is fixed on the crossbeam. A horizontal pipe is fixed on the vertical main pipe. A set of vertical auxiliary pipes evenly distributed along the length of the horizontal pipe is fixed on the horizontal pipe. A spray head is fixed at the bottom of each vertical auxiliary pipe. A liquid tank is provided on the support. A connecting pipe is installed between the bottom of the liquid tank and the vertical main pipe. A delivery pump is installed on the connecting pipe. An on / off switch is installed on the trolley handle. The on / off switch is connected to the wiring of the drive motor and the high-speed spindle motor.The push handle here controls the direction of the tea pruning machine. The shaft, wheels, first chain gear, drive motor, second chain gear, and first chain drive the two wheels to rotate, allowing the tea pruning machine to move forward at a constant speed without manual pushing. The drive motor can be replaced with a gasoline engine as the power source. The pruning mechanism here allows for efficient, rapid, and even pruning of the tea tree tips. The spraying mechanism sprays nutrient solution onto the freshly pruned tea tree tips, promoting faster healing, stimulating the growth of lateral buds and shoots, and resulting in more and stronger tea bushes. The pruning mechanism works as follows: A high-speed main shaft motor is started, which drives the first rotating shaft to rotate at high speed via a first belt. The high-speed rotation of the first rotating shaft drives the second rotating shaft to rotate at high speed synchronously via a second belt. The high-speed rotation of the second rotating shaft then drives the third rotating shaft to rotate at high speed synchronously via a third belt, thereby synchronously driving each cutting blade to rotate at high speed to cut the top of the tea tree. The spraying mechanism works as follows: A delivery pump is started, drawing nutrient solution from the liquid tank and delivering it through a connecting pipe to the vertical main pipe, which then flows through a horizontal pipe to each vertical auxiliary pipe. Finally, nutrient solution is sprayed from each spray head onto the pruned top of the tea tree.

[0006] Further improvements include a horizontal plate on the side of the vertical mounting frame, on which a fourth, fifth, and sixth rotating shaft are rotatably connected. A square rod is fixed to the top of each of the fourth, fifth, and sixth rotating shafts. Square guide holes are opened on the bottom surfaces of the first, second, and third rotating shafts, and each square rod is inserted into one of these guide holes. A pair of opposing threaded rods are fixed to the horizontal plate. A seventh and eighth rotating shaft are rotatably connected to the vertical mounting frame, with two threaded rods threaded into them respectively. A third chain gear is installed on both the seventh and eighth rotating shafts. A servo motor is mounted on the vertical mounting frame, and a fourth chain gear is fixed to the shaft of the servo motor. A second chain is installed between the two third chain gears and the fourth chain gear. Cutting blades are installed at the bottom of the fourth, fifth, and sixth rotating shafts respectively. The horizontal plate, fourth, fifth, and sixth rotating shafts, the square rod, the square guide hole, the threaded rod, the seventh and eighth rotating shafts, the third chain gear, the servo motor, the fourth chain gear, and the second chain are used to control the height of the cutting blade, thus adapting to the pruning of tea tree tips at different heights. The working principle is as follows: Starting the servo motor drives the fourth chain gear to rotate, which in turn drives the second chain to rotate. The rotation of the second chain synchronously drives the third chain gear to rotate, which in turn drives the seventh and eighth rotating shafts to rotate. Since the threaded rod is fixed to the horizontal plate, the rotation of the seventh and eighth rotating shafts causes the threaded rod to move up and down, which in turn causes the horizontal plate to move up and down, and finally, it causes the cutting blade to move up and down. Because the square rod can move through the square guide hole, the rotation of the first, second, and third rotating shafts drives the cutting blade to rotate at high speed.

[0007] Further improvements include the installation of a high-capacity rechargeable battery on the support, which is connected to the circuit breaker, drive motor, and high-speed spindle motor. The purpose of this high-capacity battery is to provide power to the tea tree pruning machine, reducing its impact on terrain and enhancing its versatility, making it suitable for pruning tea trees in various terrains.

[0008] Further improvements include a set of transverse grooves evenly distributed along the center of each wheel on its outer contour. These transverse grooves significantly increase wheel friction, preventing slippage between the wheels and the ground during tea tree pruning machine operation (e.g., ...). Figure 7 (As shown).

[0009] Further improvements include the addition of auxiliary supports fixed to the main support on opposite sides of the two wheels, with auxiliary wheels mounted on both supports. The purpose of these auxiliary supports and wheels is to provide balanced support for the tea tree pruning machine, eliminating the need for manual assistance as with a single-sided two-wheel design, thus significantly reducing the labor intensity during tea tree top pruning.

[0010] Further improvements include the installation of an anti-slip rubber sleeve on the cart handle, with a set of notches on the sleeve. The purpose of the anti-slip rubber sleeve and notches is to greatly increase the grip on the cart handle, thereby facilitating control of the tea tree pruning machine's movement direction.

[0011] Further improvements include the addition of a self-lubricating layer on the inner contour surface of each square guide hole. The purpose of this self-lubricating layer is to reduce frictional resistance when the square rod moves across the square guide holes, resulting in smoother up-and-down movement of the cutting blade. This self-lubricating layer is made of tin bronze.

[0012] Further improvements include the addition of covers on both sides of the support to enclose the first chain. The purpose of these covers is to protect the first chain from tea tree debris, preventing it from interfering with the normal operation of the first chain and its gears, and avoiding jamming. Figure 4 (As shown).

[0013] Further improvements include a cover fixed to the support to enclose the pruning and spraying mechanisms, with a liquid collection tank installed on top of the cover. The purpose of this cover is to protect the pruning and spraying mechanisms from excessive tea tree debris, preventing them from getting stuck on the belts and affecting efficiency. Furthermore, the liquid collection tank, located on top of the cover, allows for a larger volume and holds more nutrient solution without interfering with the efficient operation of the pruning and spraying mechanisms.

[0014] Further improvements include the installation of a lifting switch on the trolley handle to control the forward and reverse rotation of the servo motor. This lifting switch is connected to the high-capacity rechargeable battery and the servo motor circuitry. The function of this lifting switch is to facilitate the forward and reverse rotation of the servo motor, thereby controlling the rotation of the second chain, the up and down movement of the horizontal plate, and ultimately the height of the cutting blades, allowing for convenient control of pruning the tea bush tips at different heights.

[0015] The beneficial effects of this invention are: 1) The two wheels can be driven to rotate through the shaft, wheels, first chain gear, drive motor, second chain gear, and first chain, so that the tea tree pruning machine can move forward at a constant speed without manual pushing; 2) The pruning mechanism enables efficient, rapid, and even pruning of the tea tree tips; 3) The spraying system can spray nutrient solution on the top of the tea tree after it has been pruned, which makes the pruned area heal faster, stimulates the growth of lateral buds and shoots, and makes the tree form more and stronger branches. 4) The height of the cutting blade can be controlled by the horizontal plate, the fourth rotating shaft, the fifth rotating shaft, the sixth rotating shaft, the square rod, the square guide hole, the threaded rod, the seventh rotating shaft, the eighth rotating shaft, the third chain gear, the servo motor, the fourth chain gear, and the second chain, so as to adapt to the pruning of tea tree tops of different heights.

[0018] The present invention will be further described below with reference to the accompanying drawings: Referring to the attached diagram: This tea tree pruning machine includes a support 1, a trolley handle 2 fixed on the support 1, and rotating shafts 3 rotatably connected to both ends of the support 1.

An on / off switch 11 is installed on the trolley handle 2. The on / off switch 11 is connected to the drive motor 6 and the high-speed spindle motor 9-6.

[0019] A horizontal plate 9-9 is provided on the side of the vertical mounting bracket 9-1. A fourth rotating shaft 9-10, a fifth rotating shaft 9-11, and a sixth rotating shaft 9-12 are rotatably connected to the horizontal plate 9-9. A square rod 9-13 is fixed to the top of each of the four rotating shafts 9-10, 9-11, and 9-12. Square guide holes 9-20 are opened on the bottom surfaces of the first rotating shaft 9-2, the second rotating shaft 9-3, and the third rotating shaft 9-4. Each square rod 9-13 is inserted into a square guide hole 9-20. A pair of opposing threaded rods 9-22 are fixed to the horizontal plate 9-9. A seventh rotating shaft 9 is rotatably connected to the vertical mounting bracket 9-1. -14 and the eighth shaft 9-15, two threaded rods 9-22 are threaded to the seventh shaft 9-14 and the eighth shaft 9-15 respectively. The seventh shaft 9-14 and the eighth shaft 9-15 are each equipped with a third chain gear 9-16. The vertical mounting bracket 9-1 is equipped with a servo motor 9-17. The shaft of the servo motor 9-17 is fixed with a fourth chain gear 9-18. A second chain 9-19 is installed between the two third chain gears 9-16 and the fourth chain gear 9-18. The cutting blades 9-5 are respectively installed at the bottom of the fourth shaft 9-10, the fifth shaft 9-11 and the sixth shaft 9-12.

[0020] A high-capacity rechargeable battery 12 is installed on the support 1. The high-capacity rechargeable battery 12 is connected to the circuit of the shut-off switch 11, the drive motor 6, and the high-speed spindle motor 9-6.

[0021] The outer contour of the two wheels 4 is provided with a set of transverse grooves 4-1 evenly distributed along the center of the wheels 4.

[0022] Auxiliary supports 13 fixed on the support 1 are provided on opposite sides of the two wheels 4, and auxiliary wheels 14 are installed on both auxiliary supports 13.

[0023] The trolley handle 2 is fitted with an anti-slip rubber sleeve 2-1, and the anti-slip rubber sleeve 2-1 has a set of notches 2-1a.

[0024] Each square guide hole 9-20 has a self-lubricating layer 9-20a on its inner contour surface.

[0025] Both sides of the support 1 are fixed with covers 15 that cover the first chain 8 respectively.

[0026] A cover 16 is fixed on the support 1 to cover the trimming mechanism 9 and the spraying mechanism 10, and a liquid tank 10-6 is installed on the top of the cover 16.

[0027] The trolley handle 2 is equipped with a lifting switch 17 that controls the forward and reverse rotation of the servo motor 9-17. The lifting switch 17 is connected to the high-capacity rechargeable battery 12 and the wiring of the servo motor 9-17.

[0028] The working principle of this invention is as follows: In use, first press the lifting switch 17 to start the servo motor 9-17. The servo motor 9-17 drives the fourth chain gear 9-18 to rotate, which in turn drives the second chain 9-19 to rotate. The rotation of the second chain 9-19 synchronously drives the two third chain gears 9-16 to rotate, which in turn synchronously drives the seventh rotating shaft 9-14 and the eighth rotating shaft 9-15 to rotate. Since the threaded rod 9-22 is fixed at the horizontal plate 9-9, the rotation of the seventh rotating shaft 9-14 and the eighth rotating shaft 9-15 will cause the threaded rod 9-22 to move up and down. This causes the horizontal plate 9-9 to move up and down, and finally, it causes the cutting blade 9-5 to move up and down to adjust its position. After the cutting blade 9-5 is in position, the start / stop switch 11 is pressed, thereby starting the high-speed spindle motor 9-6 and the drive motors 6 on both sides. The drive motors 6 drive the two wheels 4 to rotate synchronously through the first chains 8 on both sides, thereby driving the tea tree pruning machine to move at a uniform speed. The high-speed spindle motor 9-6 drives the first rotating shaft 9-2 to rotate at high speed through the first belt 9-7. The high-speed rotation of the first rotating shaft 9-2 is then synchronized through the second belt 9-21. The high-speed rotation of the second shaft 9-3, via the third belt 9-8, causes the third shaft 9-4 to rotate at high speed. This rotation, in turn, drives the square rods 9-13 to rotate at high speed through the square guide holes 9-20. Finally, this rotation drives the fourth shaft 9-10, the fifth shaft 9-11, and the sixth shaft 9-12 to rotate at high speed, thereby causing the cutting blades 9-5 to rotate at high speed. Thus, the tea tree pruning machine moves while efficiently and evenly pruning the top of the tea tree 18. After pruning the tea tree 18, the machine will start simultaneously. The delivery pump 10-8 draws nutrient solution from the liquid tank 10-6 (which is already filled with nutrient solution) and delivers it through the connecting pipe 10-7 to the vertical main pipe 10-2. It then flows through the horizontal pipe 10-3 to each vertical auxiliary pipe 10-4. Finally, the nutrient solution is sprayed onto the top of the pruned tea tree through each sprinkler head 10-5, ensuring immediate nutrient absorption by the pruned area. This promotes faster repair, stimulates the growth of lateral buds and shoots, and results in more and stronger branches (such as...). Figure 10 As shown in the figure, it is worth promoting and applying.
