Description

Technical Field

[0001] This utility model relates to a tobacco leaf topping device, belonging to the technical field of tobacco leaf topping. Background Technology

[0002] In tobacco cultivation, topping is a crucial step in improving yield and quality, preventing nutrient dispersion by removing flower buds. Existing literature (CN213463049U) discloses a tobacco topping device, including a traveling device and a cutting device, a wind duct, a fan, a pesticide tank, and a spray pipe mounted on the traveling device. The wind duct, fan, and cutting device are located at the front end of the traveling device, while the pesticide tank is located at the rear end. The wind duct is angled downwards, and the fan faces the wind duct. A cutting device for cutting tobacco leaves is located below the fan, and the pesticide tank is connected to the spray pipe. However, in this device, the cutting device is installed at the front end of the traveling device, and its structure is only suitable for single rows, resulting in low efficiency. Furthermore, the angled setting of the wind duct means that the downward airflow it generates cannot sufficiently compress the tobacco leaves, leading to missed topping or damage to the leaves during cutting. Utility Model Content

[0003] Based on the above, this utility model provides a tobacco leaf topping device to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a tobacco leaf topping device, comprising: Push frame; The traveling wheels are rotatably mounted on the front center of the push frame; The top-mounting mechanism includes a support frame, a V-shaped plate, a drive motor, and a rotating plate. The support frame is installed on both sides of the push frame, the V-shaped plate is installed on the top outer side of the support frame, the V-shaped plate has a forward-facing V-shaped opening, the drive motor is installed at the rear end of the V-shaped plate, and the rotating plate is installed on the output shaft of the drive motor.

[0005] In one example, it also includes: The blowing mechanism includes a blower and an air guide tube. The blower is fixed to the rear of the push frame. One end of the air guide tube is connected to the blower, and the other end is connected to the air guide cavity inside the V-shaped plate. The air guide cavity is formed on both sides of the V-shaped opening, and multiple air guide ports are opened on both sides of the V-shaped plate. The air guide ports are connected to the air guide cavity.

[0006] In one example, the pusher includes a U-shaped frame, a push rod, and a handrail. The walking wheels are rotatably mounted inside the U-shaped frame, the push rod is inclined at the middle of the rear end of the U-shaped frame, and the handrail is mounted on the top of the push rod.

[0007] In one example, the rear end of the U-shaped frame is provided with a fixing plate, and the hair dryer is mounted on the fixing plate.

[0008] In one example, the rear of the U-shaped frame is inclined downwards and has a support frame with support wheels.

[0009] In one example, the support frame includes a support plate, a sliding sleeve, an adjusting sleeve, a vertical column, and a horizontal beam. The support plate is laterally disposed on both sides of the push frame. The sliding sleeve is slidably mounted on the support plate. The adjusting sleeve is mounted on the side of the sliding sleeve. The vertical column is adjustablely mounted inside the adjusting sleeve. The horizontal beam is disposed on the top outer side of the vertical column. The inner rear end of the V-shaped plate is connected to the horizontal beam.

[0010] The beneficial effects of this invention are as follows: A tobacco leaf topping device is composed of a pusher frame, traveling wheels, and a topping mechanism. The traveling wheels move through the furrows, and during this movement, the top stems of the tobacco plants enter the V-shaped plates, where they are then cut off by rotating blades, thus achieving the topping operation. Compared with existing technologies, this device guides the topping process by installing two V-shaped plates on both sides of the traveling wheels and pusher frame, and the rotating blades rotate synchronously on both sides to cut, completing the topping of two rows in one operation, resulting in higher work efficiency. Furthermore, before cutting, a blowing mechanism blows air vertically downwards, directly and effectively pressing down the tobacco leaves, solving the problem of insufficient oblique wind force leading to tobacco leaf damage or missed topping in existing technologies.

[0012] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 5 This embodiment provides a tobacco leaf topping device, which includes a pusher frame 1, a traveling wheel 2, and a topping mechanism 3.

[0014] The push frame 1 includes a U-shaped frame 11, a push rod 12, and a handrail 13. The traveling wheels 2 are rotatably mounted inside the U-shaped frame 11 via a pivot. The push rod 12 is obliquely fixed to the middle of the rear end of the U-shaped frame 11, and the handrail 13 is mounted on the top of the push rod 12. The forward movement of the traveling wheels 2 can be controlled by the handrail 13.

[0015] To ensure the stability of the movement of the push frame 1, a support frame 15 is installed at the rear of the U-shaped frame 11 at an angle downwards. A support wheel 16 is provided at the bottom of the support frame 15, so that there is a support wheel 16 on each side of the rear end of the push frame 1. The two support wheels 16 and the traveling wheel 2 together form a stable three-point support.

[0016] The top-mounting mechanism 3 includes a support frame 31, a V-shaped plate 32, a drive motor 33, and rotating plates 34. The support frame 31 is installed on both sides of the push frame 1. The V-shaped plate 32 is installed on the top outer side of the support frame 31. The V-shaped plate 32 has a V-shaped opening facing forward. The drive motor 33 is installed at the rear end of the V-shaped plate 32, and its output shaft extends downward to the bottom surface of the V-shaped plate 32. Multiple rotating plates 34 are installed on the output shaft of the drive motor 33, and the drive motor 33 drives the rotating plates 34 to rotate.

[0017] The tobacco leaf topping device is composed of a pusher frame 1, a walking wheel 2, and a topping mechanism 3. The walking wheel 2 moves in the furrow. During the forward movement, the top stems of the tobacco plants enter the V-shaped plate 32 and are then cut off by the rotating blade 34, thereby realizing the topping operation.

[0018] To prevent damage to the tobacco leaves during topping, a blowing and pressing mechanism 4 is also provided, which includes a blower 41 and an air guide 42. A fixing plate 14 is provided at the rear end of the U-shaped frame 11, and the blower 41 is mounted on the fixing plate 14. One end of the air guide 42 is connected to the blower 41, and the other end is connected to the air guide cavity inside the V-shaped plate 32. The air guide cavity is formed inside the V-shaped opening on both sides of the V-shaped plate 32. Correspondingly, at the bottom of the air guide cavity, i.e., on the V-shaped plate 32, multiple air guide ports 43 are provided, and the air guide ports 43 are connected to the air guide cavity. Thus, as the V-shaped plate 32 moves forward, the blower 41 delivers air to the air guide cavity inside the V-shaped plate 32 through the air guide 42, and blows it vertically downward from the air guide ports 43 to blow and press the tobacco leaves on the tobacco plants downward, keeping them as far away from the V-shaped plate 32 as possible to avoid scratching.

[0019] For ease of operation, the support frame 31 includes a support plate 311, a sliding sleeve 312, an adjusting sleeve 313, a vertical column 314, and a transverse beam 315. The support plate 311 is horizontally arranged on both sides of the push frame 1 and is square in shape. The sliding sleeve 312 is slidably and adjustablely mounted on the support plate 311, and the adjusting sleeve 313 is mounted on the side of the sliding sleeve 312. The vertical column 314 is adjustablely mounted inside the adjusting sleeve 313. The transverse beam 315 is located on the top outer side of the vertical column 314, and the rear inner side of the V-shaped plate 32 is connected to the transverse beam 315. The advantages of this structure are that, on the one hand, it avoids the support frame 31 and the V-shaped plate 32 from scratching the tobacco leaves, and on the other hand, the transverse position of the V-shaped plate 32 can be adjusted by the sliding sleeve 312, and the height position of the V-shaped plate 32 can be adjusted by the adjusting sleeve 313, thus adapting to the topping operation of tobacco leaves with different row spacing and different heights.

[0020] For ease of operation, the support frame 31 includes a support plate 311, a sliding sleeve 312, and a mounting plate. The support plate 311 is horizontally fixed on both sides of the push frame 1. The support plate 311 is square in shape. The sliding sleeve 312 is slidably mounted on the support plate 311. The mounting plate is mounted on the side of the sliding sleeve 312. The electric push rod 12 is mounted on the mounting plate. After the sliding sleeve 312 is adjusted to the predetermined position, it is fixed on the support plate 311 by fastening screws, thereby realizing the horizontal adjustment of the fixed position.
