[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] like Figure 1-Figure 2 As shown, an embodiment of the present application provides an online lateral tobacco leaf sampling device for threshing and redrying, which is applied to a threshing and redrying production line. After the tobacco leaves are threshed and stemmed, in order to ensure the stability of the tobacco leaf quality, it is necessary to sample the produced tobacco leaves and conduct a size structure inspection. In the sampling process, a certain amount of tobacco leaves are manually taken directly from the tobacco leaf conveyor belt. After the tobacco leaves are threshed, large, medium and small pieces of tobacco leaves are distributed in the tobacco leaves, which causes the tobacco leaves transported on the conveyor belt to be stratified. Therefore, when the tobacco leaves are manually taken, the distribution of large, medium and small pieces in the taken tobacco leaf samples is uneven. For example, more large tobacco leaves may be taken, or more small tobacco leaves may be taken, which cannot truly reflect the distribution of tobacco leaves of various sizes actually transported on the conveyor belt. Therefore, the objective accuracy of the detection result is insufficient. The online lateral tobacco leaf sampling device for threshing and redrying of the present application aims to be more uniform when sampling, and truly reflect the composition of tobacco leaves of various sizes in the transported tobacco leaves.

[0023] The lateral tobacco leaf sampling device for threshing and redrying comprises a frame 1 and a belt conveyor 6, wherein the frame 1 is arranged on the conveying path of tobacco leaves. Preferably, the lateral tobacco leaf sampling device for threshing and redrying is suitable for tobacco leaves that are conveyed in a falling manner. For example, there are two sections of conveying belts along the conveying path of tobacco leaves, and the heights of the conveying belts of the two sections are different. Tobacco leaves fall freely from the conveying belt of the front section to the conveying belt of the rear section. The lateral tobacco leaf sampling device for threshing and redrying is arranged on the free-falling path of tobacco leaves, and tobacco leaves can pass through the space on the frame 1. The belt conveyor 6 can be adjusted. The belt conveyor 6 is arranged on the frame 1, and the belt conveyor 6 can move back and forth along the frame 1. When the belt conveyor 6 moves to the first position, the belt conveyor 6 stops the freely falling tobacco leaves, so that the tobacco leaves fall on the belt conveyor 6, and then the tobacco leaves can be sampled evenly. When the belt conveyor 6 moves to the second position, the belt conveyor 6 avoids the freely falling tobacco leaves, so that the tobacco leaves continue to be conveyed normally. Through this method, the belt conveyor 6 is moved to realize the sampling of tobacco leaves, the sampling is more uniform, and can truly reflect the structural distribution of tobacco leaves of various sizes in the produced tobacco leaves.

[0024] In this embodiment, a cylinder 4 is provided on the frame 1, and the cylinder 4 drives the belt conveyor 6 to move back and forth. The structure is simple and the driving operation is smoother. When it is necessary to take a tobacco leaf sample, the cylinder 4 drives the belt conveyor 6 to the first position. When the sampling is completed, the cylinder 4 drives the belt conveyor 6 to the second position.

[0025] Preferably, the belt conveyor 6 can be horizontally movably arranged on the frame 1, and the movement of the belt conveyor 6 on the frame 1 is carried out along the horizontal direction, which is beneficial to reducing the load of the cylinder 4, and the movement is also more stable to avoid tobacco leaves falling.

[0026] Along the moving direction of the belt conveyor 6, a slide bar 2 is arranged on the frame 1, and the slide bar 2 is arranged in a straight line. A slider 3 is arranged at the bottom of the belt conveyor 6, and the slider 3 can move linearly along the slide bar 2. Under the mutual cooperation of the slider 3 and the slide bar 2, the reciprocating movement of the belt conveyor 6 is made straighter and more stable. More preferably, the number of sliders 3 is two, and the two sliders 3 are arranged at intervals at the bottom of the belt conveyor 6. The arrangement direction of the two sliders 3 and the reciprocating movement square of the belt conveyor 6 are parallel to each other, and the two sliders 3 and the slide bar 2 are limited to each other, which further improves the straightness of the movement of the belt conveyor 6, and the movement of the belt conveyor 6 is also more stable.

[0027] In this embodiment, a hanging bracket 7 is also provided on the belt conveyor 6, and a caster 8 is provided on the hanging bracket 7. The caster 8 can slide on the frame 1. Under the action of the caster 8, it is helpful to reduce the resistance of the reciprocating movement of the belt conveyor 6, so that the reciprocating movement of the belt conveyor 6 is smoother, and the smoothness of the equipment operation is improved.

[0028] Preferably, the number of casters 8 is two, and the two casters 8 are arranged at intervals along the moving direction of the belt conveyor 6. The arrangement direction of the two casters 8 and the moving direction of the belt conveyor 6 on the frame 1 are parallel to each other. In this way, the two casters 8 are arranged at intervals, which further improves the stability of the belt conveyor 6 during movement. In order to prevent the belt conveyor 6 from tipping over, in this embodiment, two brackets 7 can be provided, and one bracket 7 can be provided, and two casters 8 can be provided on one bracket 7. The layout can be carried out according to the actual situation. Design, in this embodiment, an elevated frame is provided on the frame 1, the elevated frame extends upward from the top of the frame 1, the casters 8 slide along the top of the elevated frame, the top of the elevated frame forms a structure similar to a beam and has a certain length, the two casters 8 can reciprocate along the top of the elevated frame, the elevated frame is higher than the frame 1, and the bracket 7 also extends upward from the top of the belt conveyor 6, so that the belt conveyor 6 is conducive to maintaining a horizontal state, making the entire movement and adjustment process of the belt conveyor 6 more stable, and through the cooperation of the elevated frame and the bracket 7, the layout design of the equipment space is convenient.

[0029] In this embodiment, along the conveying direction of the belt conveyor 6, the slider 3 is arranged close to one end of the belt conveyor 6, and the hanger 7 is arranged close to the other end of the belt conveyor 6, so that the two supporting points are respectively close to the two ends of the belt conveyor 6. In this way, the support for the belt conveyor 6 is more stable. In addition, the hanger 7 forms a hanging bearing mode for the belt conveyor 6, and the center of gravity is more stable, which prevents the belt conveyor 6 from tipping over during the movement.

[0030] In some examples, one cylinder 4 can be provided, and the reciprocating action of the cylinder 4 enables the belt conveyor 6 to be reciprocated and adjusted. Preferably, a plurality of cylinders 4 are provided, and the plurality of cylinders 4 are distributed on both sides of the belt conveyor 6 along the way on the frame 1. In this embodiment, the conveying direction of the belt conveyor 6 is the length direction, which can also be described as the along-way direction. On the frame 1, cylinders 4 are arranged on both sides of the belt conveyor 6 along the way, and the axes of the output ends of the cylinders 4 on both sides are horizontally arranged, but the output ends of the cylinders 4 on both sides are in opposite directions. In this way, the movement of the belt conveyor 6 is realized by the mutual cooperation of the cylinders 4 on both sides, so that the movement and adjustment of the belt conveyor 6 are smoother and more stable. More preferably, the cylinders 4 on each side are evenly spaced along the length direction of the belt conveyor 6, so as to further improve the stability of the force applied to the belt conveyor 6.

[0031] Preferably, the belt conveyor 6 may include a trough body with upper and lower openings, in which a conveying belt and a motor 5 are arranged, and the conveying belt is driven by the motor 5. Tobacco discharge outlets are respectively arranged at both ends of the length of the trough body to discharge the received tobacco leaves outward, thereby improving the convenience of the tobacco sampling process.
