[0025] The attached figure shows the preferred embodiment of the automatic topping and bud-suppressing device for tobacco. The following is a more detailed description of this application in conjunction with the attached figure.
[0026] Depend on Figs. 1 to 4 As shown, an automatic tobacco topping and bud suppression device includes a U-shaped housing 1 with its opening facing downwards, meaning that the bottom and front and rear sides of the housing 1 are open to facilitate the entry and exit of the top of the tobacco stem. The top or side of the housing 1 is provided with connecting components, such as nut sleeves or insertion holes, which can be installed on a plant protection machine to achieve topping operations at a uniform height.
[0027] The casing 1 is internally fixed with two interval arranged clamping rods 2, the upper part between the two clamping rods 2 is provided with a blade 3, the blade 3 is connected with a servo motor 4, the servo motor 4 is fixedly connected with the casing 1. The top of the tobacco stem enters into the casing 1 through the channel between the two clamping rods 2, when moving to the blade 3, the rotating blade 3 driven by the servo motor 4 cuts off the top of the tobacco stem, achieving the purpose of cutting and suppressing buds.
[0028] Through cutting and suppressing buds, the top end advantage of tobacco can be eliminated, and the accumulation of leaf nutrients can be promoted. Mainly because after the tobacco plant blooms, the top bud will continuously consume a large amount of nutrients, resulting in thin and light middle and lower leaves due to insufficient nutrients. After cutting, the top end advantage is broken, and the nutrients are redistributed to the leaves, promoting leaf dry matter accumulation and improving the development conditions of middle and upper leaves. After cutting, the axillary buds at the leaf axils of the plant will quickly germinate, and if not controlled in time, they will consume a large amount of nutrients, reducing tobacco yield and quality. Through artificial bud removal (such as removing 3-4 cm axillary buds), the regeneration of axillary buds can be effectively inhibited.
[0029] At the same time, it can also reduce the risk of disease transmission. The top bud and the axillary bud are easy to attract pests such as tobacco aphids and tobacco night moths, and become a medium for the spread of viruses such as cucumber mosaic virus. After cutting, such ecological niche is reduced, indirectly inhibiting the spread of diseases.
[0030] In order to facilitate the top of the tobacco stem to enter between the two clamping rods 2, the front end of the clamping rod 2 is outwardly inclined and provided with a guide rod 201, and the two guide rods 201 are arranged in a V shape.
[0031] The top rear end of the casing 1 is provided with a downwardly arranged spray head 12, the spray head 12 is connected with a water or nutrient solution supply system, when the cut tobacco moves below the spray head 12, the spray head 12 sprays water or nutrient solution to it, keeps the cut end moist, accelerates callus formation, and reduces the probability of pathogen (such as bacterial wilt, black tuber disease) invasion. Also, fungicides can be sprayed through the spray head 12 to further prevent diseases. Also, spraying auxin substances (such as naphthalene acetic acid) can simulate the auxin concentration produced by the top bud to inhibit the germination of lateral buds.
[0032] The casing 1 is provided with a sensor 11, the spray head 12 is an electrically controlled spray head, and the sensor 11 is electrically connected with the spray head 12. The sensor 11 is used for detecting the position of the tobacco stem movement, and a light barrier photoelectric sensor can be used. The emitting part and the receiving part of the light barrier photoelectric sensor are arranged on the two sides below the spray head 12.
[0033] In this embodiment, the rear end of the clamping rod 2 is provided with a stop rod 5, the top rear end of the casing 1 is connected with a support frame 10, a rotating shaft 7 is rotatably arranged on the support frame 10, the rotating shaft 7 is fixedly connected with the clamping rod 2 through a connecting rod 6, a sweeping plate 9 is arranged on the rotating shaft 7, and the sensor 11 is arranged on the support frame 10 and cooperates with the sweeping plate 9.
[0034] The sensor 11 is a touch switch, an infrared sensor or a photoelectric sensor. The torsional spring 8 is sleeved on the rotating shaft 7, one end of the torsional spring 8 is fixedly connected with the rotating shaft 7, and the other end of the torsional spring 8 is fixedly connected with the support frame 10. The stop lever 5 is arranged flush with the clamping rod 2. In the free state, the stop lever 5 abuts against the end of the clamping rod 2.
[0035] When the tobacco stem after topping moves to the stop lever 5, the stop lever 5 is pushed to move around the axis of the rotating shaft 7, and the rotating shaft 7 is rotated, the rotating rotating shaft 7 drives the sweeping plate 9 to rotate, when the sweeping plate 9 contacts or blocks the sensor 11, the sensor 11 detects the signal and transmits it to the electrically controlled nozzle 12, and the nozzle 12 sprays the solution.
[0036] By using the arrangement, the tobacco branch number completed in a working cycle can be counted, data acquisition is realized, and the establishment of a big data model in the later period is facilitated, thereby providing important parameter support for intelligent and fine planting.
[0037] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application.
