Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production, in particular to a leaf shearing machine for tobacco processing. Background Technique

[0002] Tobacco is an annual herbaceous plant of the genus Nicotiana in the Solanaceae family. Tobacco is native to South America and is widely cultivated in provinces and regions across China. Tobacco prefers warm and sunny environments, is not cold-tolerant, is relatively heat-tolerant, and likes fertile, deep, and well-drained soil. Tobacco mainly relies on vegetative propagation and sowing for reproduction.

[0003] In order to improve the planting yield of tobacco, during the planting and maintenance of tobacco, it is necessary to regularly shear the tobacco leaves.

[0004] For example, a leaf shearing machine for tobacco processing with the publication number CN214676709U starts a first motor, and the output end of the first motor drives a lead screw to rotate. Through the threaded cooperation between the lead screw and the movable plate, the movable plate is driven to move vertically to adjust the height of the leaf shearing cylinder. When the height of the leaf shearing cylinder is adjusted, a second motor is started, and the output end of the second motor drives the blade to rotate, thereby shearing the tobacco, thus achieving the effect of being applicable to different growth stages of different varieties of tobacco seedlings. However, its device still has certain defects;

[0005] During the planting of tobacco, in addition to regularly shearing the tobacco leaves, it is also necessary to repel insects or increase nutrition for the tobacco. Therefore, it is necessary to spray medicine on the tobacco, and it is impossible to carry out spraying and leaf shearing together, which greatly reduces the work efficiency and increases the labor cost.

[0006] Therefore, we propose a leaf shearing machine for tobacco processing to solve the problems raised above. Content of the Utility Model

[0007] The purpose of the utility model is to provide a leaf shearing machine for tobacco processing to solve the problem that in the planting of tobacco by the existing leaf shearing machines for tobacco processing on the current market, in addition to regularly shearing the tobacco leaves, it is also necessary to repel insects or increase nutrition for the tobacco. Therefore, it is necessary to spray medicine on the tobacco, and it is impossible to carry out spraying and leaf shearing together, which greatly reduces the work efficiency and increases the labor cost.

[0008] To achieve the above object, the utility model provides the following technical solutions: A tobacco leaf shearing machine for tobacco processing, including a leaf shearing mechanism, a ball screw, a connecting strip, and a leaf shearing blade. A rolling wheel mechanism is installed below the leaf shearing mechanism, and a servo motor is installed on the lower surface of the leaf shearing mechanism. Moreover, a ball screw is arranged above the servo motor. A slider is installed on the ball screw, and connecting strips are symmetrically installed on the left and right sides of the slider. Moreover, a movable box is installed at the reverse end of the connecting strip. A limiting rod is installed inside the leaf shearing mechanism, and the limiting rod penetrates through the connecting strip. A fan mechanism is arranged below the connecting strip, and the fan mechanism blows air outwards. Ventilation holes and movable grooves are formed on both the left and right sides of the leaf shearing mechanism. A movable box is installed at the reverse end of the connecting strip, and a leaf shearing blade is installed below the movable box. Moreover, a first medicine box and a second medicine box are arranged inside the leaf shearing blade. A liquid inlet is installed above the second medicine box, and a through hole is formed on one side of the second medicine box close to the first medicine box. A medicine spraying pipe is installed on the front surface of the first medicine box, and an atomizing nozzle is installed below the medicine spraying pipe.

[0011] Preferably, the servo motor is connected to the ball screw through an output shaft, and the ball screw is located inside the leaf shearing mechanism. A sliding connection structure is formed between the ball screw and the slider.

[0012] With the above structural design, when the servo motor is started, the servo motor drives the ball screw to rotate through the output shaft. The ball screw drives the slider to move up and down. The slider drives the movable box to move up and down through the connecting strip, so as to drive the leaf shearing blade on the movable box to move up and down, thus facilitating the shearing of tobacco at different heights.

[0013] Preferably, two limiting rods are provided, and the limiting rods are symmetrically arranged along the center line of the ball screw. Moreover, a sliding connection structure is formed between the limiting rods and the connecting strip.

The leaf shearing and spraying can be carried out together, greatly improving the working efficiency.

[0021] Compared with the prior art, the beneficial effects of the present utility model are:

[0022] 1. When starting the servo motor of the leaf shearing machine for tobacco processing, the servo motor drives the ball screw to rotate through the output shaft.

And a servo motor 3 is installed on the lower surface of the leaf shearing mechanism 1. The upper part of the servo motor 3 is connected to the ball screw 4 through an output shaft, and the ball screw 4 is located inside the leaf shearing mechanism 1. A sliding connection structure is formed between the ball screw 4 and the slider 5. When the servo motor 3 is started, the servo motor 3 drives the ball screw 4 to rotate through the output shaft. The ball screw 4 drives the slider 5 to move up and down. The slider 5 drives the movable box 12 to move up and down through the connecting bar 6, thereby driving the leaf shearing blade 13 on the movable box 12 to move up and down, so as to facilitate shearing tobacco at different heights.
