Description

Technical Field

[0001] The present invention relates to the technical field of agricultural implements, and in particular, to an inclined cutting topping and bud suppressing device. Background Art

[0002] During the tobacco planting process, the topping and bud suppressing operation is a key link to ensure the quality and yield of tobacco leaves, directly affecting the final economic value of tobacco leaves. According to the agronomic requirements of tobacco planting, the topping and bud suppressing operation needs to be completed on the same day, and the shorter the interval time between topping and bud suppressing operations, the better the effect. Existing tobacco topping and bud suppressing equipment usually mainly adopts a flat cutting structure. The flat cut stubble after cutting will cause the tobacco stalk to be hollow when rainwater falls later, thus affecting the growth of tobacco leaves.

[0003] For example: Chinese Patent (Publication No. CN 117530068 A, Publication Date: February 9, 2024) discloses a tobacco topping, bud suppressing and collecting integrated machine, including a moving mechanism, a topping mechanism, a bud suppressing mechanism, and a collecting mechanism. The topping mechanism is fixedly arranged at the front end of the moving mechanism and is used for clamping and cutting the apical bud of the tobacco plant and transporting the cut apical bud of the tobacco plant to the collecting mechanism; the bud suppressing mechanism is fixedly arranged at the rear end of the moving mechanism and is used for spraying a bud suppressing agent on the tobacco plant after cutting the apical bud of the tobacco plant. Although the above solution can realize the functions of tobacco topping, bud suppressing and collecting, the bud suppressing agent is sprayed, which is easy to cause liquid splashing and there is a phenomenon of uneven spraying; when using a disc cutter for topping, it is easy to produce a stubble, and rainwater will infect the wound and cause hollow stem disease. In addition, there is a problem that the tobacco stalk is easy to shake during topping. Summary of the Invention

[0036] Embodiment 1:

[0037] This embodiment provides an inclined topping and bud suppressing device, as Figures 1 - 4 shown, which includes a tobacco stalk supporting device 11, a topping mechanism 1, a bud suppressing mechanism 3, and a fireworks collecting device 2. The tobacco stalk supporting device 11 can straighten the tobacco stalk and keep it in an upright state, guiding it into the topping area; the topping mechanism 1 located in the topping area is installed obliquely, so that an inclined cut is formed at the top of the tobacco stalk, which is beneficial to rainwater drainage and reduces the risk of disease infection; the bud suppressing mechanism 3 is arranged behind the topping mechanism 1 and can carry out bud suppressing operation immediately after topping; and the fireworks collecting device 2 realizes fireworks collection while topping.

[0038] In this embodiment, the tobacco stalk supporting device 11 includes two symmetrically arranged tobacco stalk supporting components. The tobacco stalk supporting components include hook parts, and the two hook parts form a V-shaped guiding space; the rear side of the hook part is a horizontal section, and there is a certain gap between the two horizontal sections, forming a channel for the tobacco stalk to pass through; the setting direction of the horizontal section is along the front-back direction of the device.

[0039] As Figures 1 - 4 shown, the topping mechanism 1 includes a topping moving knife 13, a topping fixed knife 14, and a topping motor 12. The topping fixed knife 14 is fixed to the horizontal section of one of the tobacco stalk supporting components. According to the moving direction of the device, the topping fixed knife 14 in this embodiment is installed on the left tobacco stalk supporting component; the inner side surface of the front end of the topping fixed knife 14 is an inclined knife surface, and the inclined knife surface cooperates with the tobacco stalk supporting component on its opposite side to gradually guide the tobacco stalk to the rear side of the topping fixed knife 14, so as to fix the tobacco stalk together with the horizontal section of the tobacco stalk supporting component on the opposite side, facilitating the cutting of the topping moving knife 13; the topping fixed knife 14 plays a fixing role. Due to the existence of its inclined knife surface, it can gradually lock the topped tobacco stalk to avoid the tobacco stalk shaking during topping and can form a regular inclined fracture.

[0040] The topping moving knife 13 is arranged above the topping fixed knife 14. In order to make the tobacco stalk form an inclined fracture, the topping moving knife 13 is inclined; according to the moving direction of the device, the left end of the topping moving knife 13 is lower than the right end, according toFigure 2 and Figure 4 In the shown view direction, the left end of the topping moving knife 13 is higher than the right end. The angle between the topping moving knife 13 and the horizontal plane is an acute angle, and this angle meets the rainwater drainage requirements.

[0041] The topping moving knife 13 is driven by a topping motor 12 to rotate. The topping motor 12 is arranged above the topping moving knife 13, and the output end of the topping motor 12 is connected to the middle position of the topping moving knife 13, and the axis of the topping motor 12 is perpendicular to the knife surface of the topping moving knife 13; when the topping motor 12 rotates, the topping moving knife 13 rotates around the axis of the topping motor 12 to cut off the fireworks at the top of the tobacco stalk. In this embodiment, the topping fixed knife 14 and the lifter 11 cooperate to fix the tobacco stalk, which can ensure the accuracy of the cutting of the topping moving knife 13 and make the cut of the tobacco stalk consistent.

[0042] In order to reduce the risk of wound infection of the cut tobacco stalk, the topping moving knife 13 and the topping motor 12 in this embodiment are installed in an inclined manner, so that the cut of the tobacco stalk is in a downward inclined state. Among them, the topping moving knife 13 is installed on the power output shaft of the topping motor 12, and the motor output shaft is installed with a fixed bearing seat 15 to ensure the smooth and efficient rotation process of the moving knife.

[0043] In the moving direction of the device, a bud suppressing mechanism 3 is arranged at the rear side of the lifter 11 and the topping mechanism 1. The bud suppressing mechanism 3 in this embodiment is installed adjacent to the topping mechanism 1, and can perform bud suppressing treatment immediately after topping, improving work efficiency. As Figure 3 and Figure 4 shown, the bud suppressing mechanism 3 includes a rolling brush 31, a touch switch 32 and a bud suppressing agent medicine box 33. The touch switch 32 is arranged at the rear end of the lifter 11, and its installation position is slightly lower than the topping moving knife 13, so that the tobacco plant after topping can smoothly touch the touch switch 32. The touch switch 32 can adopt a travel switch.

[0044] The bud suppressing agent medicine box 33 is installed at the rear side of the mounting bracket 43. The bud suppressing agent medicine box 33 contains the bud suppressing agent. The bud suppressing agent medicine box 33 is led to the rolling brush 31 through a pipeline, and a valve is installed on the pipeline. Both the touch switch 32 and the valve are connected to the control system; when the tobacco plant touches the touch switch 32, the control system sends a signal to open the valve, and the bud suppressing agent flows along the pipeline to the rolling brush 31.

[0045] The rolling brush 31 is installed at the rear side of the touch switch 32 through a bracket. In this embodiment, a group of horizontally arranged rolling brushes 31 are arranged at the rear side of the touch switch 32, and a group of vertically installed rolling brushes 31 are arranged on each side of the horizontal rolling brush 31. The horizontal rolling brush 31 is used to apply the bud suppressing agent to the top of the tobacco plant, and the vertical rolling brush 31 is used to apply the bud suppressing agent to the side of the tobacco plant. The bud suppressing agent is applied to the tobacco plant in multiple directions through the cooperation of the horizontal rolling brush 31 and the vertical rolling brush 31, improving the bud suppressing effect. And, in this embodiment, the bud suppressing agent is applied by smearing, which can avoid the splashing of the liquid medicine compared with the spraying method.

[0046] The two sets of vertical rotary brushes 31 are parallel to each other and have a certain spacing, which allows the tobacco plants to pass through smoothly. During the movement of the device, the tobacco plants come into contact with the rotary brushes 31, causing the rotary brushes 31 to rotate and realizing the smearing action.

[0047] In order to collect the tobacco flowers while topping, a tobacco flower collecting device 2 is provided in this embodiment. The tobacco flower collecting device 2 includes a collecting flap 21 and a collecting container 22. As Figure 4 shown, the collecting flap 21 is installed on the back side of the topping moving knife 13 (the side opposite to the cutting surface) and is perpendicular to the knife surface of the topping moving knife 13; the collecting flap 21 is symmetrically arranged with respect to the topping motor 12 and maintains the same inclination angle as the topping motor 12. When the topping motor 12 drives the topping moving knife 13 to rotate, the collecting flap 21 rotates together with the topping moving knife 13, and is used to cooperatively guide the tobacco flowers to deviate from the cutting direction and be thrown towards the collecting side, that is, the tobacco flowers to be cut off are thrown into the collecting container 22.

[0048] The shape of the collecting flap 21 can be set arbitrarily. For example, the unilateral collecting flap 21 can be rectangular, trapezoidal or triangular, etc. In order to effectively collect the tobacco flowers, the collecting container 22 is arranged on the lower side of the lower end of the topping moving knife 13; among them, the collecting container 22 can be a collecting basket, a collecting box, a collecting bag or other containers with a loading capacity.

[0049] The topping mechanism 1, the tobacco stalk supporting device 11, and the bud suppressing mechanism 3 are all installed on the lifting mechanism 4, and their heights can be adjusted to meet the operation requirements of tobacco plants at different heights. As Figures 1 - 4 shown, the lifting mechanism 4 of this embodiment includes a mounting frame 43, a lifting motor 42 and a parallelogram mechanism 41. The topping mechanism 1 and the tobacco stalk supporting device 11 are both connected to the mounting frame 43. A set of parallelogram mechanisms 41 are installed at both ends of the mounting frame 43, and the two sets of parallelogram mechanisms 41 are connected by a connecting rod; the fixed end of the lifting motor 42 is installed at the middle position of the connecting rod, and the driving end of the lifting motor 42 is hinged to the mounting frame 43.

[0050] Among them, the lifting motor 42 is a linear motor, which can drive the mounting frame 43 and its upper components to move up and down under the action of the parallelogram mechanism 41; the parallelogram mechanism 41 has a stable structure and is convenient for controlling the verticality and stability of the lifting.

[0051] The working process of the topping and bud suppressing device in this embodiment is as follows:

[0052] (1) Tobacco stalk supporting and guiding:

[0053] The topping and bud suppressing device travels along the ridge, and the tobacco stalk supporting device 11 straightens the tobacco stalks and guides them into the topping area, so that the tobacco plants reach the topping fixed knife 14 stably.

[0054] (2) Inclined topping:

[0055] The topping fixed knife 14 cooperates with the lifter 11 to fix the tobacco plant. The topping moving knife 13 rotates around the motor shaft and tilts to cut off the top flower bud under the drive of the topping motor 12, forming a downward-tilted incision at the top of the tobacco plant. The cut flower bud is thrown into the collection container 22 under the guidance of the collection paddle 21, realizing topping and synchronous collection.

[0056] (3) Applying bud inhibitor:

[0057] After the topped tobacco stalk passes through the topping area, it triggers the travel switch, and the bud inhibitor is evenly applied to the tobacco plant by the horizontal and vertical brush rollers 31.

[0058] It should be noted that according to the change in the height of the tobacco plant, the heights of topping and bud inhibition can be adjusted through the lifting mechanism 4 to ensure the accuracy of the operation.

[0059] The topping and bud inhibition device of this embodiment simultaneously has the functions of topping, bud inhibition, and flower bud collection. The topping and bud inhibition are linked and controlled for synchronous operation. The inclined topping structure ensures a reasonable incision direction. Combined with the automatically triggered bud inhibition mechanism 3 of the coating type, it realizes a comprehensive bud inhibition treatment for the topping part; cooperating with the lifting mechanism 4, it adapts to the operation requirements of different plant heights; and through the flower bud collection device 2, it realizes the efficient and centralized recovery of flower buds.

[0060] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
