Description

Technical Field

[0001] This utility model relates to the field of flue-cured tobacco harvesting technology, specifically to a portable hollow flue-cured tobacco grading platform. Background Technology

[0002] Tobacco leaf grading is a crucial link in the purchase and circulation of flue-cured tobacco. Its purpose is to determine and grade the appearance quality indicators of tobacco leaves, such as color, maturity, leaf structure, oil content, identity, and chroma, in accordance with national flue-cured tobacco standards, so as to achieve a balance between high quality and high price and industrial usability.

[0003] During the tobacco grading process, a large number of tobacco leaf fragments and non-tobacco substances (tobacco stems, tobacco dust, ash, debris, mud, etc.) will be scattered and left on the grading worktable or the ground. If they are not collected in a centralized manner, they may be mixed into the graded tobacco leaves, affecting the quality and purity of the tobacco leaves and damaging environmental hygiene.

[0004] On the other hand, the existing flue-cured tobacco grading tables use fully welded connections for all components, resulting in a large overall size and weight. After the purchasing season, multiple people are needed to move and load them onto trucks, which is labor-intensive, occupies transportation space, and is prone to weld cracking due to bumps. When purchasing across different sites, vehicles cannot carry a sufficient number of grading tables at once, causing delays in the purchasing process. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a portable hollow tobacco grading table. The grading table has a simple structure, is easy to use, and can collect tobacco leaf fragments and non-tobacco substances. Moreover, its components can be folded or disassembled, making it easy to carry.

[0006] The technical solution adopted to achieve the above-mentioned objectives of this utility model is as follows:

[0007] A portable perforated tobacco grading table includes an operating table and a ash collection hopper. The operating table includes an operating platform with one or more ash-leaking components. The ash collection hopper is detachably installed on the operating platform and is located directly below one or more ash-leaking components.

[0008] The operating platform has one or more slag leakage ports. The slag leakage component includes a slag leakage frame and a slag leakage structure composed of multiple slag leakage pipes. The multiple slag leakage pipes are distributed at equal intervals, and both ends of each slag leakage pipe are installed on the slag leakage frame. Each slag leakage frame is installed on the corresponding slag leakage port, and each slag leakage structure is located directly below the corresponding slag leakage port.

[0009] Both the slag outlet and the slag frame are square, and the size of the slag outlet matches the size of the slag frame. The top of each slag frame is welded to the bottom of the corresponding slag outlet, and each slag frame and the corresponding slag outlet constitute a slag channel.

[0010] In each of the aforementioned slag-leaking components, multiple slag-leaking pipes are distributed at equal intervals along the length direction of the slag-leaking frame. Multiple through holes are provided on the two side frames of the slag-leaking frame in both length directions. The two ends of each slag-leaking pipe pass through the corresponding two through holes on the two side frames of the slag-leaking frame in both length directions, and each slag-leaking pipe is welded to the side frames of the slag-leaking frame in both length directions.

[0011] It also includes a clamping component. A pair of abutment bars are symmetrically provided at the inlet of the slag hopper. The clamping component includes two pressure rods and two locking components. The operating platform also includes a bracket. The bracket includes a platform support frame. The platform support frame includes two first support rods. The two first support rods are symmetrically fixed to the bottom of the operating platform and are parallel to each other. The two pressure rods are symmetrically distributed between the two first support rods. The ends of the two pressure rods on the same side are respectively hinged to one of the first support rods. The two pressure rods can rotate in a plane perpendicular to the first support rods. The locking parts of the two locking components are respectively installed on the ends of the two pressure rods on the same other side. The locking parts of the two locking components are respectively installed on the other first support rod. The slag hopper inlet is close to the bottom of the operating platform and is located between the two first support plates. The two pressure rods press the two abutment bars on the slag hopper respectively. The other ends of the two pressure rods are locked to the other first support rod by locking components.

[0012] The locking element is a spring pin.

[0013] The platform support frame also includes two symmetrically distributed second support rods, which are located between the two first support rods. The ends of the two second support rods on the same side are respectively fixedly connected to one of the first support rods, and the ends of the two second support rods on the same other side are respectively fixedly connected to the other first support rod. The two second support rods are perpendicular to the two first support rods and are located outside the two pressure rods.

[0014] The support also includes four legs, which are arranged in a square. The upper ends of the four legs are connected to the two first support rods at their respective positions by 90-degree self-locking hinges. The upper ends of the four legs are located at the four corners of the square structure formed by the two second support rods and the two first support rods.

[0015] The slag receiving hopper outlet is equipped with a pull-out gate, and a baffle is provided on the side of the gate opposite to the pull-out side.

[0016] Compared with the prior art, the beneficial effects and advantages of this utility model are as follows:

[0017] 1. The grading station is equipped with a slag leakage port and slag leakage components on the operating platform, and a slag receiving hopper is set below the operating platform. Tobacco leaf fragments and non-tobacco substances are collected in the slag receiving hopper through the slag leakage port and slag leakage components. On the one hand, this prevents tobacco leaf fragments and non-tobacco substances from mixing into the graded tobacco leaves, thereby improving the quality and purity of the tobacco leaf grade and ensuring environmental hygiene. On the other hand, it can also prevent hand cuts during the grading operation and facilitate the grading operation.

[0018] 2. In this grading platform, the slag receiving hopper is detachably installed below the operating platform. At the same time, since the four legs of the support can be folded inward, after the grading operation is completed, the slag receiving hopper can be disassembled and the four legs can be folded up to disassemble and store the entire grading platform. This reduces the labor intensity and transportation space required for handling the grading platform, improves the transfer efficiency of the grading platform, and thus improves the harvesting efficiency of flue-cured tobacco.

[0030] In this embodiment, the support legs 3 are made of stainless steel and have a height of 0.8m. The four support legs 3 are arranged in a square pattern. The upper ends of the four support legs 3 are connected to the corresponding positions on the two first support rods 4 via 90-degree self-locking hinges 6. The upper ends of the four support legs 3 are located at the four corners of the square structure formed by the two second support rods 5 and the two first support rods 4. The four support legs can be folded up using the four 90-degree self-locking hinges 6.

[0031] like Figure 4 and Figure 5 As shown, the operating platform 2 has two symmetrically distributed slag leakage ports 7, which are square in shape. In this embodiment, the length of the slag leakage port 7 is 0.6m and the width is 0.44m.
