Description
Technical Field
[0001] The utility model belongs to the technical field of tobacco planting, and particularly relates to a topping device used for tobacco planting. Background Art
[0002] Tobacco is an important economic crop, its leaves used to produce a variety of tobacco products. The quality and yield of tobacco leaves directly impact the quality and economic benefits of these products. To improve tobacco yield and quality, various management techniques are employed in agricultural practices, with topping being a key measure.
[0003] Tobacco topping involves manually removing the growing point and terminal bud at the top of the tobacco plant at a certain growth stage. This process typically occurs before flowering or when the inflorescence is just forming. The main purpose of topping is to suppress apical dominance, promote leaf growth and development, and improve tobacco yield and quality.
[0004] However, when topping is performed manually, the cross-sections produced after topping are mostly irregular. If it rains after topping, rainwater will accumulate in the irregular cross-sections, causing the tobacco leaves to develop hollow core disease, affecting the yield of tobacco leaves. Utility Model Content
[0005] In view of the above shortcomings, the purpose of the present invention is to provide a topping device for tobacco planting to solve the monitoring and early warning problems in the prior art.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Through the above scheme, the cutting component can cut the tobacco rod in the limiting component at an angle to form an inclined cross-section, and make the top of the tobacco rod after topping a smooth inclined shape, reducing the probability of rainwater accumulation in the cut area on rainy days, thereby reducing the probability of hollow disease forming after the tobacco leaves are toppled.
[0009] Furthermore, the support frame is a lifting frame, and a handrail is provided on the support frame.
[0010] Through the above further solution, the support frame is a lifting frame that can adjust the height of the top plate according to the actual growth of tobacco leaves, so that the tobacco rods can be topped at a corresponding height so that the height of the tobacco rods after topping meets the requirements.
[0011] Furthermore, a V-shaped guide groove is provided on the guide plate, the guide groove has an end facing the opening larger than an end facing the limit assembly, and the guide groove is connected to the opening.
[0012] Through the above further solution, the design of the V-shaped guide groove can more accurately guide the tobacco rod into the limiting assembly, thereby limiting the tobacco rod to the cutting area, ensuring that each tobacco leaf can be correctly positioned and processed, and reducing the possibility of misoperation.
[0013] Furthermore, the limiting assembly includes a fixed rod, a fixed block, and a baffle. The guide plate is fixedly connected to a fixed rod on one side of the small end of the guide groove and on both sides of the guide groove.

[0015] Furthermore, the limiting assembly also includes a stopper and a spring. The fixed block is provided with a groove body on the side facing the guide groove. One end of the stopper is rotatably connected to the groove body. The spring is provided in the groove body, one end of which is fixedly connected to the bottom of the groove body, and the other end is fixedly connected to the stopper.
[0016] Through the above further solution, when the cigarette rod enters between the fixed blocks from the guide groove, the cigarette rod is attached to the two blocks, and the blocks rotate into the groove body, so that the spring is subjected to force. After the cigarette rod passes through the blocks, the blocks are reset under the action of the spring. At this time, the cigarette rod is between the baffle and the two blocks and will not come out of the baffle and the two blocks, thereby constraining the position of the cigarette rod and ensuring that the cigarette rod is accurately positioned.
[0017] Furthermore, the cutting assembly includes a U-shaped plate, a telescopic rod and a cutter, the U-shaped plate includes a long vertical plate, a short vertical plate and a horizontal plate, the two ends of the horizontal plate are respectively connected to the end of the long vertical plate and the end of the short vertical plate, the long vertical plate and the horizontal plate are fixedly connected end to end on the lower side of the top plate, the horizontal plate is provided with a telescopic rod inclined through the base, the cutter is fixedly installed on the movable end of the telescopic rod, the short vertical plate is provided with an oblique opening, and one end of the telescopic rod for mounting the cutter passes through the oblique opening to the fixed block.
[0018] Through the above further solution, after the position of the cigarette rod is constrained, the cutter is driven by the telescopic rod to move toward the direction close to the cigarette rod and cut the cigarette rod, thereby achieving the effect of topping.
[0019] Furthermore, four spray pipes penetrating the top plate are provided at the four corners of the top plate, and a plurality of spray heads are provided on the spray pipes at the lower side of the top plate.
[0020] With the above further solution, the design of the spraying pipe and the spraying head enables topping and spraying to be carried out simultaneously.
[0021] Furthermore, wheels are provided at the four corners of the bottom of the support frame for facilitating movement.
[0022] Through the above further solution, the design of the wheels allows the entire topping device to be easily moved in the field, reducing the difficulty and labor intensity of manual handling.
[0023] Compared with the prior art, the beneficial effects of the present invention are:
[0024] The cutting assembly can cut the tobacco stem in the limiting assembly at an angle to form an inclined cross-section, and make the top of the tobacco stem after topping into a smooth inclined shape, thereby reducing the probability of rainwater accumulation in the cut surface on rainy days, and thereby reducing the probability of hollowness forming after the tobacco leaves are toppled.
