Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf production, in particular to a tool for cleaning the bottom leaves of tobacco leaves. Background Art

[0002] Tobacco bottom leaves refer to the lower leaves of the tobacco plant close to the ground. Usually, due to insufficient light and weak photosynthesis, tobacco bottom leaves are thin, contain less substances, and have relatively poor quality. For example, the nicotine and sugar content is not ideal, which makes it difficult to meet the requirements of the cigarette industry. In addition, because the bottom leaves are close to the ground, they are easily attacked by pathogens and pests in the soil, and the risk of infection is high. Therefore, they have disadvantages such as poor quality and susceptibility to diseases. At the same time, removing the bottom leaves can increase the ventilation and air permeability of the tobacco field, allowing the middle and upper leaves to receive more light, thereby improving the quality of the middle and upper tobacco leaves. Therefore, it is urgent to provide a tool that can quickly and easily remove the bottom leaves of tobacco leaves. Utility Model Content

DETAILED DESCRIPTION

[0012] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0013] As shown in the figure, the utility model proposes a tool for removing the bottom leaves of tobacco leaves, including an inverted L-shaped bracket 1 and a pull rod 2, the pull rod 2 is connected to the inner side of the vertical end of the bracket 1 through a positioning plate 3, the lower side of the horizontal end of the bracket 1 is connected to the pull rod handle 5 through two compression springs 4, the top of the pull rod 2 is connected to one side of the pull rod handle 5, an upper limit plate 6 is arranged at the bottom of the vertical end of the bracket 1, a fixed knife spacer 9 is connected to the side of the bracket 1 below the upper limit plate 6, a plurality of fixed knives 7 are equidistantly sleeved on the fixed knife spacer 9, a movable knife slide 10 is arranged outside the pull rod 2 below the upper limit plate 6, a plurality of movable knives 8 are equidistantly connected to the outside of the movable knife slide 10, each movable knife 8 is separated by a movable knife spacer 11, the movable knife spacer 11 is sleeved on the outside of the movable knife slide 10, and a lower limit plate 15 is arranged at the bottom of the fixed knife spacer 9 and the movable knife slide 10.

[0014] The number of the movable knives 8 is one less than the number of the fixed knives 7, and in a static state, the movable knives 8 correspond one by one to the fixed knives 7 from bottom to top until the second fixed knives 7 from the top.

[0015] The distance between two adjacent fixed knives 7 is fixed at 30 mm, and the distance between two adjacent movable knives 8 is 30 mm.

[0016] An upper washer 13 and a lower washer 14 are arranged at the connection positions between the two sides of the fixed knife 7 and the fixed knife spacer 9 .

[0017] A moving knife sliding sleeve 12 is arranged inside the moving knife 8 and the moving knife spacer sleeve 11 , and the moving knife sliding rod 10 passes through the moving knife sliding sleeve 12 , so that the moving knife sliding sleeve 12 can move vertically on the moving knife sliding rod 10 .

[0018] The fixed knife is connected to the bottom of the bracket, and the movable knife is connected to the bottom of the pull rod. The bracket and the pull rod are fixed at a distance by a positioning plate. The fixed knife is separated by a fixed knife spacer to ensure that the distance between each fixed knife is consistent. The compression spring is between the bracket handle and the pull rod handle. In a non-working state, the compression spring will not be compressed. When the pull rod handle is held tightly, the compression spring is compressed, and the movable knife is driven to move upward by pulling the pull rod handle to intersect with the fixed knife, thereby achieving the purpose of removing the invalid bottom leaves of tobacco leaves. At the same time, the movable knife is separated by a movable knife spacer to ensure that the distance between each movable knife is consistent. In order to ensure that the up and down movement of the movable knife blade is in a stable and reliable state, a movable knife sliding sleeve is built in the movable knife and the movable knife spacer, and the movable knife sliding rod passes through the movable knife sliding sleeve, and limit plates are set at both ends of the sliding rod.
