Description

Technical Field

[0001] This utility model relates to the technical field of tobacco field implements, specifically to a device that integrates tobacco topping and bud suppression with tobacco seed collection. Background Technology

[0002] Due to rising labor costs and technological advancements, Western countries pioneered the mechanization of topping and bud suppression, achieving full mechanization by the 1960s. They primarily developed large-scale equipment and focused on multi-functionality, high speed, wide coverage, precision, and electromechanical-hydraulic integration. However, European and American equipment is unsuitable for my country's hilly and mountainous terrain, and its design is mainly geared towards flat field operations. While topping efficiency is high, a fixed height can lead to damage to the top leaves. Furthermore, the diversity and complexity of tall crops necessitate more customized and adaptable topping and bud suppression machines to meet the different growth habits and environmental requirements of various plants. For example, crops such as tobacco, cotton, and corn have different growth characteristics, requiring topping and bud suppression machines to be flexible and adjustable to improve yield and quality.

[0003] A prior art patent (CN207476301U) discloses a method comprising a first spray head, a second spray head, a sprout inhibitor delivery pipe, and a disinfectant delivery pipe, as well as a first and second pair of hinged shear blades. The first shear blade is connected to a first shear handle, and the second shear blade is connected to a second shear handle. The first spray head is mounted on the first shear blade, and the second spray head is mounted on the second shear blade, both of which are connected to the sprout inhibitor delivery pipe. A sponge block is provided on the side of the second shear blade that cuts against the first shear blade, and a disinfectant spray hole is provided on the second spray head opposite the sponge block, connected to the disinfectant delivery pipe. This method reduces manual labor, improves efficiency, and continuously disinfects the blades during pruning to prevent virus transmission and increase the yield of tobacco crops.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] Currently, topping of tall crops mainly relies on manual labor, followed by pruning and bud suppression. These operations need to be completed on the same day and cannot be done simultaneously. Manual topping is labor-intensive, and workers are often exposed to harmful chemicals, which affects their health.

[0006] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a device that integrates tobacco topping and bud suppression with tobacco firework collection. This solves the problem that in traditional technologies, topping of tall crops mainly relies on manual labor, followed by pruning and bud suppression. The operation must be completed on the same day and cannot be carried out simultaneously. Manual topping is labor-intensive, and workers are often exposed to harmful chemicals, which affects their health.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] The device integrates tobacco topping and bud suppression with plant collection, including a gantry frame. The gantry frame has a lifting frame that moves vertically up and down via a lifting structure. Below the lifting frame, two converging rods are arranged side by side, gradually widening in the forward direction, and forming a plant guide channel through the area between the two converging rods.

[0010] The lifting frame is equipped with a rotatable top-pressing blade in the area above the plant guide channel, and a fireworks collection box located on one side of the top-pressing blade is fixed to the lower end of the lifting frame.

[0011] The lifting frame is equipped with a sprout inhibitor nozzle in the area between the tail ends of the two gathering rods.

[0012] As an optimized solution, the top-tapping cutter includes a vertically rotating shaft, and baffles are vertically fixed to the opposite side walls of the shaft near its lower end, with a cutting edge fixed to the lower surface of the baffles.

[0013] As an optimized solution, the baffle is vertically fixed to the outer wall of the rotating front with a limiting plate.

[0014] As an optimized solution, ventilation holes are evenly distributed on the baffle.

[0015] As an optimized solution, the lifting frame is fixedly connected to a motor via a motor mount, the output end of the motor is connected to a speed reducer, and the upper end of the rotating shaft is connected to the output end of the speed reducer.

[0016] As an optimized solution, two sets of parallel four-bar linkages are arranged side by side on the gantry frame. The two ends of the two sets of parallel four-bar linkages are respectively hinged to the gantry frame and the lifting frame. A lifting electric cylinder is hinged to each set of parallel four-bar linkages on the gantry frame, and the extension end of the lifting electric cylinder is hinged to the parallel four-bar linkage.

[0017] As an optimized solution, the upper port of the fireworks collection box is open, and a baffle at a 90° angle is fixedly connected to the upper port of the fireworks collection box.

[0018] As an optimized solution, a horizontal shaft is fixedly connected to the lifting frame, a rotating sleeve is rotatably mounted on the horizontal shaft, an opening rod located in the plant guide channel is vertically fixedly connected to the side wall of the rotating sleeve, and a DC normally closed solenoid valve is fixedly connected to the area of ​​the lifting frame above the horizontal shaft. When the opening rod abuts against the contact end of the DC normally closed solenoid valve, the DC normally closed solenoid valve is opened.

[0019] As an optimized solution, an arc-shaped rod is fixed to the lower end of the opening rod in the forward direction.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The gantry frame is connected to the traction equipment. The gantry frame moves across the tobacco ridge. The operator controls the height of the lifting frame by adjusting the stroke of the lifting cylinder to adapt to different tobacco plant height requirements. After the integrated device is adjusted to the appropriate height (tobacco topping position height), the gantry frame moves in a straight line across the ridge. Two gathering rods gather the tobacco plants into the plant guide channel. As the machine moves forward, the motor drives the topping blade to rotate, realizing the topping work by cutting the tobacco plants with its bottom blade.

[0022] The combination of the rotation of the top blade and the forward motion of the whole machine causes the cut fireworks to move in a parabolic motion to one side along the center line of the device. Under the constraint of gravity, the fireworks will fall into the fireworks collection box, thus realizing the collection of fireworks.

[0023] After the fireworks are cut off, the smoke stick continues to move backward along the center line of the device until it reaches the position of the sprout suppressant nozzle. When the smoke stick continues to move backward until it begins to touch the arc-shaped rod at the lower end of the opening rod, the top of the opening rod touches the DC normally closed solenoid valve due to the leverage effect. The DC normally closed solenoid valve opens, and the sprout suppressant nozzle begins to spray the sprout suppressant onto the top section of the smoke stick, thus achieving the sprout suppressant work. Due to the action of gravity, the opening rod returns to its original position, the DC normally closed solenoid valve returns to its original position, and the sprout suppressant nozzle stops spraying, completing one sprout suppressant work cycle.

[0024] The baffle uses a mesh structure because it needs to minimize air resistance to the rotational motion of the cut fireworks as it is stirred into the fireworks collection box. The limiting plates at both ends are mainly used to prevent the fireworks from moving radially along the rotation axis during this process. Attached Figure Description

Detailed Implementation

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0032] like Figures 1 to 4 As shown, the device integrates tobacco topping and bud suppression with plant collection, including a gantry frame 1. The gantry frame 1 has a lifting frame 5 that moves vertically up and down via a lifting structure. Below the lifting frame 5, two gathering rods 4 are arranged side by side. The two gathering rods 4 are arranged in a gradually expanding manner along the forward direction, and a plant guide channel is formed through the area between the two gathering rods 4.

[0033] The lifting frame 5 is equipped with a rotatable top knife 6 in the area above the plant guide channel, and a fireworks collection box 7 located on one side of the top knife 6 is fixed to the lower end of the lifting frame 5.

[0034] The lifting frame 5 is equipped with a sprout inhibitor nozzle 20 in the area between the tails of the two gathering rods 4.

[0035] The top-attacking cutter 6 includes a vertically rotating shaft 8. Baffles 12 are vertically fixed to the opposite side walls of the shaft 8 near its lower end. A blade 10 is fixed to the lower surface of the baffles 12.

[0036] The baffle 12 is vertically fixed to the outer wall of the rotating front, and the limiting plate 11 is fixed to it.

[0037] Ventilation holes 9 are evenly distributed on the baffle 12.

[0038] The lifting frame 5 is fixedly connected to the motor 14 via the motor base 13. The output end of the motor 14 is connected to the reducer 15, and the upper end of the rotating shaft 8 is connected to the output end of the reducer 15.

[0039] Two sets of parallel four-bar linkages 2 are arranged side by side on the gantry frame 1. The two ends of the two sets of parallel four-bar linkages 2 are respectively hinged to the gantry frame 1 and the lifting frame 5. A lifting electric cylinder 3 is hinged to each set of parallel four-bar linkages 2 on the gantry frame 1. The extension and retraction ends of the lifting electric cylinder 3 are hinged to the parallel four-bar linkages 2.

[0040] The upper port of the fireworks collection box 7 is open, and a baffle 12 at a 90° angle is fixedly connected to the upper port of the fireworks collection box 7.

[0041] A horizontal shaft 16 is fixedly connected to the lifting frame 5. A rotating sleeve 17 is rotatably mounted on the horizontal shaft 16. An opening rod 19 located in the plant guide channel is vertically fixedly connected to the side wall of the rotating sleeve 17. A DC normally closed solenoid valve 18 is fixedly connected to the area of ​​the lifting frame 5 above the horizontal shaft 16. When the contact end of the opening rod 19 abuts against the DC normally closed solenoid valve 18, the DC normally closed solenoid valve 18 is opened.

[0042] The outlet of the normally closed DC solenoid valve 18 is connected to the inlet of the sprout inhibitor nozzle 20 via a pipe, and the inlet of the normally closed DC solenoid valve 18 is connected to the outlet of the medicine tank, which is housed in the traction device or the main control box.

[0043] An arc-shaped rod is fixed to the lower end of the opening lever 19 in the forward direction.

[0044] The working principle of this device is as follows:

[0045] The gantry frame 1 is connected to the traction equipment. The gantry frame 1 travels across the tobacco ridge. The operator controls the height of the lifting frame 5 by controlling the stroke of the lifting cylinder 3 to adapt to different tobacco plant height requirements. After the integrated device is adjusted to the appropriate height (tobacco topping position height), the gantry frame 1 travels in a straight line across the ridge. The two gathering rods 4 gather the tobacco plants in the plant guide channel. As the machine moves forward, the motor 14 drives the topping blade 6 to rotate, realizing the topping work by cutting the fireworks with its bottom blade 10.

[0046] The combination of the rotation of the top blade 6 and the forward motion of the whole machine causes the cut fireworks to move in a parabolic motion to one side along the center line of the device. Under the constraint of gravity, the fireworks will fall into the fireworks collection box 7, thus realizing the collection of fireworks.

[0047] After the fireworks are cut off, the smoke stick continues to move backward along the center line of the device until it reaches the position of the sprout suppressant nozzle 20. When the smoke stick continues to move backward until it begins to touch the arc-shaped rod at the lower end of the opening rod 19, the top of the opening rod 19 touches the DC normally closed solenoid valve 18 due to the leverage effect. The DC normally closed solenoid valve 18 opens, and the sprout suppressant nozzle 20 begins to spray the sprout suppressant onto the top section of the smoke stick, thus realizing the sprout suppressing work. Due to the action of gravity, the opening rod 19 returns to its original position, the DC normally closed solenoid valve 18 returns to its original position, and the sprout suppressant nozzle 20 stops spraying, completing one sprout suppressing work cycle.

[0048] The baffle 12 adopts a mesh structure because it needs to minimize the air resistance to its rotational motion during the process of agitating the cut fireworks into the fireworks collection box 7. The limiting plates 11 at both ends are mainly used to prevent the fireworks from moving radially along the rotation axis 8 during this process.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
