Description

Technical Field

[0001] This utility model relates to the field of industrial auxiliary structure technology, specifically to a bench structure for a leaf-laying platform. Background Technology

[0002] A leaf-laying machine is a device that evenly and quantitatively lays tobacco leaves on a conveyor belt, commonly used in the pre-treatment stage of tobacco processing, such as leaf threshing and re-drying. Existing leaf-laying machines can adjust and control the amount and speed of leaf laying, and can also be integrated with intelligent raw tobacco preparation systems to achieve automated operation, improve the uniformity of material feeding, and increase production efficiency.

[0003] During production, to ensure the effective leaf spreading of the leaf spreader, staff need to continuously observe the uniformity of the leaf spreading on the conveyor belt. To reduce the workload of staff and mitigate the decline in work accuracy and efficiency caused by fatigue from prolonged work, staff typically move movable chairs to a location such as the aisle next to the leaf spreader before the start of each shift, so they can sit and work after production begins. Furthermore, staff must remove the movable chairs before cleaning the production area after each shift. However, moving the movable chairs back and forth is inconvenient, takes up considerable space, and failure to remove them promptly after production can hinder cleaning and obstruct movement in the aisles. In addition, because the placement of the movable chairs is not fixed, there is a safety hazard if the chairs are placed too close to the leaf spreader, potentially causing staff sitting on them to accidentally come into contact with machine components (such as the conveyor belt). Utility Model Content

[0004] This invention aims to overcome the shortcomings of the existing technology by providing a foldable bench for a leaf-picking, re-drying, and leaf-laying machine.

[0005] The present invention adopts the following technical solution to solve the technical problem: a foldable bench for a leaf-picking, re-drying and leaf-laying machine, wherein the leaf-picking, re-drying and leaf-laying machine is provided with a side panel as a frame, including ear pieces, a rotating shaft assembly, a bench body and a support plate; A pair of ear pieces are symmetrically arranged on both sides of the stool body; each ear piece includes an installation part and a connecting part. The installation part is fitted and fixed to the side wall, and its end near the stool body is folded towards the side away from the side wall to form the connecting part; a limiting vertical hole is opened on the upper edge of the connecting part, and a limiting hole is opened outward from the top of the limiting vertical hole towards the side away from the side wall. The rotating shaft assembly is symmetrically fixed on both sides of the stool body. A pair of rotating shaft assemblies are respectively installed in a pair of limiting vertical holes or a pair of limiting holes. The rotating shaft assembly can slide up and down along the limiting vertical holes when the stool body is upright, and can be located in the limiting holes when the stool body is laid flat. The support plate is fixedly installed at the bottom of the stool body. When the stool body is laid flat, a gap is left between it and the side wall, and when the stool body is laid flat, the support plate presses against the side wall.

[0006] Furthermore, the rotating shaft assembly is a cylindrical shaft with one side flattened to form a platform structure; When the stool body is upright, the pivot assembly is engaged and locked into the limiting vertical hole, and the platform structure fits against the side wall of the limiting vertical hole near the side wall.

[0007] Furthermore, it also includes connecting bolts; a through mounting hole is provided on the mounting part, and the connecting bolt passes through the mounting hole and engages with the side panel thread to fasten it, thereby fixing the lug to the side panel.

[0008] Furthermore, the mounting hole is an elongated oval hole arranged vertically along its length.

[0009] Furthermore, the mounting part has two mounting holes arranged vertically.

[0010] Furthermore, the edge of the limiting hole near the side panel is an upright straight edge, the top and the other side edges together form an outwardly convex arc edge, and the bottom edge is a horizontal straight edge.

[0011] Furthermore, the main body of the stool is formed by welding steel pipes and steel plates.

[0012] This utility model provides a foldable stool for a leaf-picking, re-drying, and leaf-laying machine, which has the following beneficial effects: 1. The main body of the stool of this utility model can be rotated into an upright state by the pivot assembly and slid down along the side along the limiting vertical hole for storage, reducing the operation or transportation space occupied by the foldable stool and avoiding obstruction of operation or transportation, making it suitable for narrow working environments; the main body of the stool can also slide up the pivot assembly into the limiting hole and then be rotated and limited to a flat position, providing a seating position for workers, reducing the fatigue of workers during long-term work, improving the efficiency of workers, and reducing work errors caused by fatigue.

[0013] 2. The platform structure of the rotating shaft assembly of this utility model enables the rotating shaft assembly to be engaged and locked into the limiting vertical hole when the stool body is upright, and to slide up and down along the limiting vertical hole. When the stool body is laid flat, the rotating shaft assembly is limited to the limiting hole, preventing the stool body from changing from a flat state to an upright state without human operation, which could cause workers to fall or get too close to the leaf-laying machine, thus ensuring the stability of the foldable stool during operation.

[0014] 3. The mounting hole of this utility model is an elongated oval hole arranged vertically along its length. The mounting height of the ear piece can be adjusted, so that the mounting height of the stool body can adapt to the seating needs of staff of different heights, and has good adaptability.

[0015] 4. This utility model has a simple structure and low manufacturing cost. It can be implemented by modifying existing equipment. Compared with movable seats, it does not require back-and-forth transportation and is more convenient to use, thus having good practicality. Attached Figure Description
