Description

Technical Field

[0001] This utility model relates to tobacco seedling leaf trimming machinery, specifically a bridge-type leaf trimming machine. Background Technology

[0002] Floating seedling raising for flue-cured tobacco is a currently advanced seedling raising method. It uses floating seedling trays within a nutrient solution tank to cultivate sufficient, uniform, disease-free, and robust seedlings of the appropriate age for field transplanting. During the cultivation process, workers typically move a frame back and forth along the sides of the tank, while a leaf-cutting machine reciprocates in the middle to cut the leaves. However, the tobacco seedlings close to the sides of the tank tend to grow outwards and branch outwards. Existing leaf-cutting machines, such as the device with publication number CN219352452U, are... Figure 1 As shown, the following problems exist: (1) The tobacco seedlings at both ends are not completely cut. After the bridge-type leaf cutter is used to cut the seedlings, the two sides still need to be trimmed separately by hand; (2) The tobacco seedlings at the stem end often block the front of the wheel. This will either crush the seedlings or get caught in the wheel, affecting the efficiency of moving forward; (3) The height adjustment of the leaf cutter is controlled by the equipment on the leaf cutter (such as the threaded rod connecting the handwheel). This requires a high level of skill from the leaf cutter, and some leaf cutters without height adjustment equipment are not convenient to use. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a bridge-type leaf shearing machine, which improves upon the technical defects of the existing bridge-type leaf shearing machine, with a simple structure, reasonable design, convenient use, and significantly improved work efficiency.

[0004] This utility model is achieved through the following technical solution: a bridge-type leaf trimmer, including a frame, a reciprocating motion box, a shearing device and a moving wheel. The bottom of the frame is provided with a connecting plate extending inward. The moving wheel is provided with a protective plate on the side near the pool sill. Both the moving wheel and the protective plate are mounted on the connecting plate.

[0005] A further preferred technical solution is that the protective plate has inwardly inclined folded edges on both sides.

[0006] A further preferred technical solution is that a triangular brace connects the connecting plate to the frame.

[0007] A further preferred technical solution is that: the upper part of the vertical rod of the frame is provided with a height adjustment plate, and the height adjustment plate is provided with a plurality of vertical connection holes; the horizontal rod of the frame is connected to the height adjustment plate by a fastener, and the fastener is provided with a connection hole, which is bolted to the corresponding vertical connection hole of the height adjustment plate as needed.

[0008] The advantages of this utility model are:

[0009] (1) Install a protective plate on the inside of the moving wheel to prevent the tobacco seedlings from being crushed or rolled into the wheel during the journey.

[0010] (2) A connecting plate extending inward is provided at the bottom of the frame, and the moving wheels are installed on the inner side of the connecting plate so that the reciprocating machine box can cut to the edge of the pool, and the tobacco seedlings at both ends can also be completely trimmed.

[0011] (3) By setting folded edges on the protective plate, the tobacco leaves can be blocked more smoothly.

[0012] (4) Triangular bracing is installed between the connecting plate and the frame to make the structure more stable.

[0013] (5) The problem of adjusting the height is solved by a simple height adjustment plate. It is economical and practical. It can also be used on leaf trimmers without height adjustment function, making it more widely applicable and saving costs. Attached Figure Description
