Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and in particular to a portable tobacco topping and bud-suppressing machine. Background Technology

[0002] The tobacco industry is a vital pillar of my country's economy and a significant pathway to increasing farmers' income. Its stable development is closely linked to the economic stability and prosperity of some provinces and cities in my country. Topping is a common technique in flue-cured tobacco production to promote leaf maturation and improve yield and quality. However, while removing apical dominance, topping also leads to nutrient redistribution, promoting axillary bud growth, which is detrimental to the growth and opening of upper leaves, severely impacting yield and quality. Therefore, while topping, it is also necessary to promptly remove side shoots and suppress buds. If this is not done in time, the upper leaves will suffer from insufficient nutrition, resulting in small, lightweight leaves, and thinner lower and middle leaves, further reducing yield and quality. Currently, topping and bud suppression in flue-cured tobacco are carried out in two separate steps: first, the top of the tobacco plant is cut off with a knife; then, a bud-suppressing agent is sprayed onto the toppled plant, or the axillary buds are removed by hand or knife after they have grown larger. The topping and bud removal of flue-cured tobacco are still mainly carried out by traditional manual step-by-step operations. This is not only labor-intensive and inefficient, but also lacks standardization and the buds are not completely suppressed, which seriously affects the yield and quality of tobacco leaves.

[0003] With my country's economic development, a phenomenon of "tobacco cultivation in the north and tobacco planting in the south" has gradually emerged. To date, the southwestern tobacco-growing region remains my country's main tobacco-producing area, accounting for approximately 60% of the national tobacco planting area. The western tobacco-growing region has diverse land types, primarily consisting of plains, hills, and plateaus. Significant topographical differences result in a highly integrated agricultural system and a wide variety of tobacco varieties.

[0004] In the device disclosed in patent number CN202011080124.7 that simultaneously performs topping and bud removal of tobacco, multiple electrical components are required to implement the topping and bud removal processes. Furthermore, the bud-suppressing agent can only be sprayed in a fixed direction, failing to evenly spray the cut surface of the topping stem, resulting in poor bud-suppressing effects. Therefore, this solution proposes a portable topping and bud-suppressing device for flue-cured tobacco. Summary of the Invention

[0005] The purpose of this invention is to provide a portable tobacco topping and bud-suppressing machine. This invention can complete the two important processes of topping and bud-suppressing in tobacco production in one go. During the process, the tobacco stalk can be manually held and broken after being positioned, and the bud-suppressing agent is automatically sprayed at the broken position, reducing the intensity of manual labor and improving work efficiency. The manual action can generate a linkage effect, and the automatic drive of breaking and return can be triggered during the linkage process. After returning to the position, the bud-suppressing agent can be automatically sprayed.

[0006] To achieve the above objectives, the present invention provides a portable tobacco topping and bud-suppressing machine, comprising: a topping mechanism, a bud-suppressing mechanism, and a handheld frame. The handheld frame is equipped with a topping mechanism for breaking tobacco stalks. The topping mechanism includes an upper breaking mechanism, a lower breaking mechanism, and a driving mechanism. Both the upper and lower breaking mechanisms can be linked together to grip the tobacco stalk. The driving mechanism is used to drive the upper and lower breaking mechanisms to rotate relative to each other and break the tobacco stalk. The handheld frame is also equipped with a bud-suppressing mechanism that triggers automatic spraying of a bud-suppressing agent after the tobacco stalk is broken.

[0007] Furthermore, the lower breaking mechanism includes a mechanical claw, a lower breaking mechanism component, and a slider. The lower breaking mechanism component is mounted on a handheld frame, and the slider is slidably connected to the lower breaking mechanism component. The front end of the mechanical claw is an arc-shaped gripper, the rear end is curved, and a kidney-shaped movable groove is provided. The two mechanical claws are symmetrically arranged, and their middle parts are hinged to the lower breaking mechanism component. The rear ends are stacked to make the movable grooves correspond to each other. A rotating bolt placed in the two movable grooves is installed on the slider.

[0008] Furthermore, the upper breaking mechanism includes an outer sleeve, an upper breaking mechanism component, a slider, and a mechanical claw. The outer sleeve is mounted on the handheld frame. The bottom of the upper breaking mechanism component is provided with an ear plate hinged to the outer sleeve. The slider is slidably connected to the upper breaking mechanism component. The front end of the mechanical claw is an arc-shaped gripper, and the rear end is curved and has a kidney-shaped movable groove. The two mechanical claws are symmetrically arranged, and their middle parts are both hinged to the upper breaking mechanism component. The rear ends are stacked so that the movable grooves correspond to each other. The slider is equipped with rotating bolts placed in the two movable grooves.

[0009] Furthermore, the drive mechanism includes a motor, a half gear, and a gear. The half gear is installed at the bottom of the ear plate of the upper component of the breaking mechanism with the outer sleeve as the center. A gear that meshes with the half gear is installed on the output shaft of the motor.

[0010] Furthermore, the top-setting mechanism also includes a linkage mechanism, which includes a small pull rod, a connecting plate, a large pull rod, and a hand lever. There are two sets of small pull rods, which are slidably connected to the upper and lower components of the breaking mechanism, respectively. Both small pull rods are fixedly connected to the sliders inside the upper and lower components of the breaking mechanism. A large pull rod is slidably connected inside the outer sleeve, and the large pull rod and the small pull rod are connected in a hinged manner through the connecting plate. The large pull rod and the small pull rod on the lower component of the breaking mechanism are connected to the hand lever.

[0011] Furthermore, a spring is also provided inside the outer sleeve to abut against the large pull rod.

[0012] Furthermore, the bud-suppressing mechanism includes a nozzle, a fixed rigid tube, a solenoid valve, and a sprayer. The fixed rigid tube is fixedly installed on the lower component of the breaking mechanism. A nozzle corresponding to the front end of the mechanical claw is installed on the fixed rigid tube. The fixed rigid tube is connected to the solenoid valve on the sprayer through a drug delivery tube.

[0013] Furthermore, the sprayer includes a medicine tank, a pump, a battery, a switch, and a controller. The pump is installed inside the medicine tank, and the pump's outlet is connected to a medicine delivery pipe. The medicine tank contains a battery, which is connected to the pump via a switch, and the switch is connected to the controller.

[0014] Furthermore, a first limit switch is installed on the upper component of the breaking mechanism, which is used to stop the motor when the upper component of the breaking mechanism flips and touches the handheld frame, thus completing the top-hitting work.

[0015] Furthermore, a second limit switch is installed on the lower component of the breaking mechanism. After the upper component of the breaking mechanism is contacted and flipped, the controller controls the solenoid valve of the sprout inhibitor to open and carry out the spraying of the sprout inhibitor.

[0016] Beneficial effects of this invention: This invention can complete the two important processes of topping and bud suppression in flue-cured tobacco production in one go. During the process, the tobacco stalk can be broken by manually determining the position and holding it, and the bud suppression agent is automatically sprayed at the broken position, which reduces the intensity of manual labor and improves work efficiency. During the process of manually driving a single action, a linkage effect can be generated, and the automatic drive of breaking and returning to the original position can be triggered during the linkage process. After returning to the original position, the bud inhibitor can be automatically sprayed. Attached Figure Description

[0021] like Figure 1-6 As shown, a portable tobacco topping and bud-suppressing machine includes: a topping mechanism, a bud-suppressing mechanism, and a handheld frame 10. The handheld frame 10 is equipped with a topping mechanism for breaking tobacco stalks. The topping mechanism includes an upper breaking mechanism, a lower breaking mechanism, and a driving mechanism. Both the upper and lower breaking mechanisms can be linked to grip the tobacco stalk. The driving mechanism drives the upper and lower breaking mechanisms to flip relative to each other, breaking the tobacco stalk. The handheld frame 10 is also equipped with a bud-suppressing mechanism that triggers the automatic spraying of a bud-suppressing agent after the tobacco stalk is broken. Specifically, the handheld frame 10 is hollow to reduce the weight of the handheld component. The handheld frame 10 and the linked mechanisms can be equipped with sensors, limit switches 22, or proximity switches to trigger the driving mechanism to start or stop after a specified action is completed, and to automatically spray or stop the bud-suppressing agent.

[0022] In this embodiment, the lower breaking mechanism includes a mechanical claw 16, a lower breaking mechanism component 21, and a slider 23. The lower breaking mechanism component 21 is mounted on the handheld frame 10, and the slider 23 is slidably connected to the lower breaking mechanism component 21. The front end of the mechanical claw 16 is an arc-shaped gripper, the rear end is curved, and a kidney-shaped movable groove 33 is provided. The two mechanical claws 16 are symmetrically arranged, and the middle part is hinged to the lower breaking mechanism component 21. The rear ends are stacked to make the movable grooves 33 correspond to each other. The slider 23 is equipped with rotating bolts placed in the two movable grooves 33.

[0023] In this embodiment, the upper breaking mechanism includes an outer sleeve 28, an upper breaking mechanism component 17, a slider 23, and a mechanical claw 16. The outer sleeve 28 is mounted on the handheld frame 10. The bottom of the upper breaking mechanism component 17 is provided with an ear plate hinged to the outer sleeve 28. The slider 23 is slidably connected to the upper breaking mechanism component 17. The front end of the mechanical claw 16 is an arc-shaped gripper, and the rear end is curved, with a kidney-shaped movable groove 33. Two mechanical claws 16 are symmetrically arranged, both hinged to the upper breaking mechanism component 17 in the middle, and their rear ends are stacked to correspond to each other's movable grooves 33. Rotating bolts placed in the two movable grooves 33 are installed on the slider 23. The mechanical claw 16 is connected to the upper breaking mechanism component 17 and the lower breaking mechanism component 21 by bolts. The large pull rods 26 and the small pull rods 24 are bonded to the connecting plate 25 by adhesive. The motor 4 frame is connected to the handheld frame 10 by screws. Specifically, as shown... Figure 2 As shown, grooves are provided on the upper component 17 and the lower component 21 of the breaking mechanism. A slider 23 is slidably connected in the groove. A protruding bolt hole is provided on the left hinge point of the mechanical claw 16, so that the installation position of the left mechanical claw 16 is higher than that of the right mechanical claw 16. This facilitates the formation of an interlaced stacking arrangement at the tail of the mechanical claw 16, and makes it easy to limit the mechanical claw 16 after the rotating bolt is inserted.

[0024] In this embodiment, the drive mechanism includes a motor 4, a half gear, and a gear 7, wherein the half gear is fitted with an outer sleeve 28. The bottom of the ear plate of the component 17 of the breaking mechanism is mounted at the center. A gear 7 that meshes with the half gear is mounted on the output shaft of the motor 4. The motor 4 is mounted on the handheld frame 10 via the motor frame 8. The output shaft of the motor 4 is connected to the gear 7 by screws, and the transmission gear 7 is connected to the shaft of the gear 7 by a key. The half gear at the flip point is connected to the component 17 of the breaking mechanism by adhesive.

[0025] In this embodiment, the top-setting mechanism further includes a linkage mechanism, which includes a small pull rod 24, a connecting plate 25, a large pull rod 26, and a hand lever 9. Two sets of small pull rods 24 are provided, each slidably connected to the upper component 17 and lower component 21 of the breaking mechanism, respectively. Both small pull rods 24 are fixedly connected to sliders 23 within the upper component 17 and lower component 21 of the breaking mechanism. The large pull rod 26 is slidably connected within the outer sleeve 28, and the large pull rod 26 is hinged to the small pull rods 24 via the connecting plate 25. The large pull rod 26 and the small pull rods 24 on the lower component 21 of the breaking mechanism are connected to the hand lever 9. In other embodiments, a spring 34 is also provided within the outer sleeve 28, abutting against the large pull rod 26. Specifically, the upper component 17 and lower component 21 of the breaking mechanism have sliding holes along their tails. Small pull rods 24 pass through these holes and connect to the slider 23. A connecting spring 34 is installed between the outer sleeve 28 and the large pull rod 26. After the top-setting is completed, releasing the hand lever 9 causes the large pull rod 26 to return to its original position under the force of the spring 34, simultaneously driving the two small pull rods 24 connected to the large pull rod 26 by the connecting plate 25 to return to their original positions. This causes the mechanical claws 16 fixed to the upper and lower components of the breaking mechanism to open. Driven by the hand lever 9, both the large pull rod 26 and the small pull rods 24 on the lower component 21 of the breaking mechanism can be driven simultaneously. This causes the small pull rods 24 to pull the slider 23, dragging the two mechanical claws 16 backward. Rotating the bolt allows it to contact the rear side of the kidney-shaped movable groove 33, driving the mechanical claws 16. This creates a driving force at the tails of the mechanical claws 16, causing them to come together and grip the tobacco stick. This ensures a stable grip on the tobacco stick after the action is performed.

[0026] In this embodiment, the bud-suppressing mechanism includes a nozzle 19, a fixed rigid tube 20, a solenoid valve 5, and a sprayer. The fixed rigid tube 20 is fixedly installed on the lower component 21 of the breaking mechanism. The nozzle 19 corresponding to the front end of the mechanical claw 16 is installed on the fixed rigid tube 20. The fixed rigid tube 20 is connected to the solenoid valve 5 on the sprayer through the drug delivery tube 13.

[0027] In this embodiment, the sprayer includes a medicine tank, a pump, a battery, a switch, and a controller 14. The pump is installed inside the medicine tank, and the pump's outlet is connected to a delivery pipe 13. The medicine tank contains a battery, which is connected to the pump via a switch, which in turn is connected to the controller 14. The manual sprayer 12 stores a sprout inhibitor. This type of sprayer contains a pump and a battery, which can be powered by charging. This type of sprayer is readily available for purchase. The manual sprayer 12 uses electricity to increase internal pressure, thereby outputting the stored sprout inhibitor from the delivery pipe 13.

[0028] In this embodiment, a first limit switch 22 is installed on the upper component 17 of the breaking mechanism. This switch stops the motor 4 after the upper component 17 flips and touches the handheld frame 10, completing the topping operation. A second limit switch 22 is installed on the lower component 21 of the breaking mechanism. This switch, upon contact with the flipped upper component 17, causes the controller 14 to open the solenoid valve 5 to spray the sprout inhibitor. Both the first and second limit switches 22 are connected to the controller 14, allowing the controller 14 to control the motor 4, pump, and solenoid valve 5 after the first and second limit switches are activated.

[0029] In other embodiments, a button 11 can be set on the handheld frame 10 and connected to the controller 14 by wires and motor 4. The state of the button 11 is transmitted to the controller 14, and then the control information of the controller 14 is transmitted to each reaction component: solenoid valve 5 and motor 4 to complete the topping and bud suppression work.

[0030] In other embodiments, the topping mechanism includes a half gear 3, a mechanical claw 16, an upper component of the breaking mechanism 17, a fixing bolt 18, a lower component of the breaking mechanism 21, a limit switch 22, a slider 23, a small pull rod 24, a connecting plate 25, a large pull rod 26, a washer 27, an outer sleeve 28, and a spring 34. When performing the topping operation, pulling the lever 9 causes the two mechanical claws 16 of the upper and lower components of the topping mechanism to close simultaneously, gripping the tobacco rod. Then, pressing the button 11 causes the motor 4 to rotate forward, driving the upper component of the breaking mechanism 17 to flip and perform the topping operation. At this time, the mechanical claws 16 of the lower component of the breaking mechanism 21 remain closed, stabilizing the tobacco rod and ensuring the normal completion of the topping operation. When the upper component of the breaking mechanism 17 triggers the limit switch 1, the controller 14 controls the motor 4 to stop. After the sprout inhibitor is sprayed, the motor 4 reverses, driving the upper component of the breaking mechanism 17 back to its original position. After touching the limit switch 2, the motor 4 stops, completing the topping operation.

[0031] The bud-suppressing mechanism includes a manual sprayer 12, a delivery tube 13, a controller 14, a solenoid valve 5, a fixed rigid tube 20, and a nozzle 19. When the component 17 on the breaking mechanism triggers the limit switch 1, the controller 14 controls the solenoid valve 5 of the bud-suppressing agent to open and spray the bud-suppressing agent. After a set time, the solenoid valve 5 closes and the motor 4 reverses, completing the bud-suppressing agent spraying operation.

[0032] The reset component includes a hand lever 9, a large pull rod 26, an outer sleeve 28, and a spring 34. After the topping and bud suppression work is completed, releasing the hand lever 9 will cause the mechanical claw 16 to open under the elastic force of the connecting spring 34.

[0033] During operation, the operator carries a manual sprayer 12 and holds the topping and bud-suppressing device. The operator places the desired topping section of the tobacco stem between the mechanical claws 16, pulls the lever 9 to close the claws 16, and then presses button 11. The motor 4 rotates forward, causing the upper component 17 of the breaking mechanism to flip and perform the topping operation. When the upper component 17 of the breaking mechanism triggers the limit switch 1, the controller 14 stops the motor 4 and simultaneously opens the bud-suppressing agent solenoid valve 5 to spray the agent. After a set time, the bud-suppressing agent solenoid valve 5 closes, the motor 4 reverses, and the upper component 17 of the breaking mechanism returns to its original position. Touching the limit switch 22 stops the motor 4, completing one topping and bud-suppressing cycle. During the return process, the lever 9 can be released, causing the mechanical claws 16 to open under the elastic force of the connecting spring 34.

[0034] This invention can complete the two important processes of topping and bud suppression in flue-cured tobacco production in one go. During the process, the tobacco stalk can be broken by manually determining the position and holding it, and the bud suppression agent can be automatically sprayed at the broken position, which reduces the intensity of manual labor and improves work efficiency. The manual action can generate a linkage effect, and the automatic drive of breaking and return can be triggered during the linkage. After returning to the position, the bud suppression agent can be automatically sprayed.

[0035] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
